Disclosure of Invention

Problems to be solved by the invention

In the pipe supporting tool described in patent document 1, the operator temporarily places the pipe on the first support member (the pipe temporarily placing band) during the pipe work, but in this case, the second support member (the pipe pressing band) is rotated around the axis of the bolt and pressed with one hand, so that a gap is secured between the first support member and the second support member.

In the pipe supporting tool described in patent document 2, although the operator does not need to continuously press the opening and closing member during the pipe work, the first supporting member and the second supporting member must be expanded to fit the pipe (see fig. 3 of the same patent document), and the workability is not necessarily good when one pipe is supported by a plurality of pipe supporting tools, and the structure in which the elastic member is disposed in the first mounting portion or the second mounting portion is not preferable because the number of parts and the number of assembly steps increase.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a pipe support tool having a simple structure and excellent workability in pipe work.

Means for solving the problems

In order to solve the above problem, a pipe support tool according to the present invention includes: the turnbuckle has a base installed on a structure and a pair of opposite pieces extending downwards from the base, a first supporting member having a first installation part and a first supporting part, the first installation part being installed in a manner of abutting against the first opposite piece in the pair of opposite pieces, the first supporting part being disposed below the first installation part, supporting a part of the circumference of a pipeline, a second supporting member having a second installation part and a second supporting part, the second installation part being installed in a manner of abutting against the second opposite piece in the pair of opposite pieces, the second supporting part being disposed below the second installation part, supporting other parts of the circumference of the pipeline and being engaged with the first supporting part, and a fastening member inserted through holes respectively formed in the first opposite piece, the second opposite piece, the first installation part and the second installation part, and fastening the first opposite piece, the second opposite piece, the first mounting part and the second mounting part; the second installation portion is provided with a butt joint piece and an inclined piece, the butt joint piece is in the first opposite piece, the second opposite piece, the first installation portion and the second installation portion under the fastened state with the butt joint of the second opposite piece, the inclined piece extends from the upper portion of the butt joint piece to the upper portion and from the direction that the second opposite piece leaves, the insertion hole of the second installation portion extends from the butt joint piece to the inclined piece and forms.

According to the pipe supporting tool, the second mounting portion is provided with the abutting piece and the inclined piece, the abutting piece abuts against the second opposing piece in a state that the first opposing piece, the second opposing piece, the first mounting portion and the second mounting portion are fastened, the inclined piece extends upwards from the upper part of the abutting piece and in a direction away from the second opposite piece, the insertion hole of the second mounting part is formed by continuing from the abutting piece to the inclined piece, therefore, when the pipeline operation is performed, the operator lifts the second supporting member so that the fastening member relatively moves from the abutting piece side to the inclined piece side in the insertion hole, and the inclined piece is abutted against the second opposite piece without abutting the abutting piece, this allows the pipe to be directly inserted into the pipe support tool with the second support member opened with respect to the first support member, and eliminates the need for the operator to continuously press the second support member during pipe work. Further, since this work can be performed without particularly increasing the number of components and the number of assembly steps as compared with the conventional pipe support tool, the pipe support tool of the present invention can improve the workability of the pipe work with a simple structure.

Preferably, the first mounting portion has a portion abutting against the first opposing piece and the abutting piece have the same or substantially the same size in the vertical direction, so that the turnbuckle can be prevented from being inclined when the fastening member is fastened.

Preferably, the fastening member is composed of a bolt inserted through the insertion holes of the first opposing piece, the second opposing piece, the first mounting portion, and the second mounting portion, and a nut screwed to the bolt, and in this case, if the first opposing piece and the second opposing piece are elastically deformable with respect to the base, a retaining portion that retains elastic deformation of the first opposing piece and the second opposing piece even if the nut is loosened with respect to the bolt is provided in the bolt or the nut, the retaining portion prevents the nut from coming off, and applies an elastic force from the first opposing piece to the first support member in a state where the inclined piece is brought into contact with the second opposing piece and the second support member is opened with respect to the first support member (at the time of temporary construction), the second support member is provided with a spring force from the second opposing piece, and the first support member and the second support member can be prevented from wobbling, thereby further improving the workability of the pipe work.

In this case, if the first mounting portion or the second mounting portion is provided with a recess that accommodates at least a part of the nut in a state of being temporarily fixed to the bolt, even if the operator moves the pipe in order to adjust the position of the pipe in the temporarily fixed state before the nut is completely tightened, the second support member is displaced vertically relative to the first support member, and the nut at least a part of which is accommodated in the recess is hooked in the recess, thereby suppressing the vertical displacement thereof, and therefore, the workability of the pipe work can be further improved.

Further, the first support portion and the second support portion may be provided with an engaging claw and an engaged portion that engage with each other, and when the fastening force of the nut to the bolt is increased, the engaging claw and the engaged portion may be firmly engaged with each other, whereby the engagement of the first support portion and the second support portion can be suppressed from being loosened. In this case, it is preferable that the second support portion is provided with a guide portion for guiding the engagement between the engagement claw and the engaged portion, in order to facilitate the engagement with the first support portion.

In the temporary fixing state before the nut is completely tightened, even if the operator moves the pipe in order to adjust the position of the pipe, the regulating portion provided in the first support portion may regulate the movement of the second support portion in the direction in which the engaging claw and the engaged portion are disengaged from each other, and the regulating portion provided in the first support portion may regulate the movement of the second support portion in the direction in which the engaging claw and the engaged portion are disengaged from each other, thereby preventing the engagement and disengagement during the adjustment of the pipe position, and thus, the workability of the pipe work may be further improved.

Preferably, the base portion may be provided with an insertion hole into which a swivel nut screwed to a suspension bolt fixed to the structure is inserted, the first opposing piece or the second opposing piece may be provided with an anti-drop portion that prevents the swivel nut from dropping out of the insertion hole, and the first opposing piece or the second opposing piece may be further provided with an insertion restriction portion that prevents the suspension bolt from being excessively inserted into the turnbuckle.

A mode for carrying out the present invention will be described based on the drawings.

As shown in fig. 1 and 2, a duct hanger 10 according to the present embodiment is used for hanging an equipment duct P of a building, and includes: a turnbuckle 20 attached to a suspension bolt B whose upper end is fixed to a ceiling or the like of a building, a band piece 30 and a band piece 40, attached to the turnbuckle 20, and a fastening member 50, and tightening (fastening) the turnbuckle 20, the band piece 30, and the band piece 40; the fastening member 50 is composed of a bolt 60 and a nut 70.

The turnbuckle 20 is formed by press working a strip-shaped steel plate, and includes a base portion 21 having a rectangular shape in plan view, and a pair of tightening pieces 22 and 23 extending downward from the base portion 21 and elastically deformable with respect to the base portion 21. An insertion hole 21a into which a rotating nut 24 screwed to the suspension bolt B is inserted is formed in the center of the base 21. A flange portion 24a (see fig. 6 and 9) having a larger diameter than the insertion hole 21a is formed at a lower portion of the swivel nut 24, and when the swivel nut 24 is screwed to the suspension bolt B, the flange portion 24a supports the periphery of the insertion hole 21a of the base portion 21 from below, and the base portion 21 is attached to the structure via the suspension bolt B.

As shown in fig. 3, the tightening piece 22 has: the first pitch portion 22a extends downward from the left edge portion of the base portion 21 (the left edge portion of the base portion 21 in fig. 3) so as to be substantially perpendicular to the base portion 21, the second pitch portion 22b extends obliquely from the lower edge portion of the first pitch portion 22a toward the tightening piece 23, and the overlapping portion 22c extends further downward from the lower edge portion of the second pitch portion 22b and overlaps the band piece 30.

The tightening piece 23 has: the first pitch portion 23a extends downward from the right edge of the base portion 21 (the right edge of the base portion 21 in fig. 3) so as to be substantially perpendicular to the base portion 21, the second pitch portion 23b extends obliquely from the lower edge of the first pitch portion 23a toward the tightening piece 22, and the overlapping portion 23c extends further downward from the lower edge of the second pitch portion 23b and overlaps the band piece 40.

In the first pitch portion 22a and the first pitch portion 23a, a retaining portion 22d and a retaining portion 23d are formed so as to stand below the swivel nut 24 so that the swivel nut 24 does not fall off from the insertion hole 21a, and in the overlapping portion 22c and the overlapping portion 23c, a round hole 22e and a round hole 23e through which the shaft portion 61 of the bolt 60 is inserted are formed.

The band piece 30 is formed by press working a band-shaped steel plate, and as shown in fig. 4, includes a suspending portion 31 and a supporting portion 32, the suspending portion 31 is attached so as to overlap and abut on the overlapping portion 22c of the tightening piece 22, and the supporting portion 32 is provided below the suspending portion 31 and supports a portion of the circumferential surface of the pipe P including the lower end Pa.

The suspending portion 31 has a substantially rectangular flat plate shape with a height dimension h, and the suspending portion 31 is formed with a circular hole 31a through which the shaft portion 61 of the bolt 60 is inserted, and a pair of protruding portions 31b, 31b that protrude outward through the circular hole 31 a. The pair of projections 31b and 31b regulate the rotation (co-rotation) of the head 62 (see fig. 6 to 9) of the bolt 60 when the nut 70 is screwed to the shaft 61 of the bolt 60.

The support portion 32 has: a bent portion 32a bent in an arc shape having a diameter equal to or substantially equal to the outer diameter of the pipe P, an enlarged diameter portion 32b provided between the suspending portion 31 and the bent portion 32a and bent in an arc shape having a diameter larger than the bent portion 32a, and an engaging claw 32c provided at the tip of the bent portion 32a and bent in a hook shape toward the outside of the arc.

The band piece 40 is formed by press working a band-shaped steel plate, and as shown in fig. 5, includes a suspending portion 41 and a supporting portion 42, the suspending portion 41 is attached so as to overlap with the overlapping portion 23c of the tightening piece 23, and the supporting portion 42 is provided below the suspending portion 41 and supports the other portion of the circumferential surface of the pipe P.

The suspending portion 41 is provided with a contact piece 43 and an inclined piece 44, the contact piece 43 contacts the tightening piece 23 in a state where the suspending portion 41 is fastened together with the tightening pieces 22 and 23 and the suspending portion 31 as described later, and the inclined piece 44 extends upward from an upper portion of the contact piece 43 and in a direction away from the tightening piece 23. The contact piece 43 has a substantially rectangular flat plate shape with a height dimension h, similarly to the suspending portion 31, and a long hole 41a through which the shaft portion 61 of the bolt 60 is inserted is formed so as to extend from the contact piece 43 to the inclined piece 44.

The support portion 42 has: a bent portion 42a bent in an arc shape having a diameter equal to or substantially equal to the outer diameter of the pipe P, an enlarged diameter portion 42b provided between the suspending portion 41 and the bent portion 42a and bent in an arc shape having a diameter larger than the bent portion 42a, and a bent portion 42d provided at the tip of the bent portion 42a and having an engaged hole 42c engaged with the engaging claw 32 c. A tapered surface 42e that guides engagement of the engaging claw 32c with the engaged hole 42c is provided on the front end side of the engaged hole 42c inside the bent portion 42 d.

In the bolt 60, the shaft portion 61 having a thread formed around it is inserted through the circular hole 31a of the suspending portion 31, the circular hole 22e of the tightening piece 22, the circular hole 23e of the tightening piece 23, and the long hole 41a of the suspending portion 41 in this order, and the head portion 62 abuts against the suspending portion 31. The nut 70 is screwed to a portion of the shaft portion 61 protruding from the elongated hole 41 a. The shaft portion 61 of the bolt 60 is provided with a retaining portion 61a, and the thread surface of the retaining portion 61a is irregularly processed to retain the nut 70, so that even if the nut 70 is loosened to the retaining portion 61a, the head portion 62 and the nut 70 apply a force toward the inside of the turnbuckle 20 to the tightening piece 22 and the tightening piece 23 via the suspending portion 31 and the suspending portion 41, and the elastic deformation of the tightening pieces 22 and 23 with respect to the base portion 21 is maintained. Then, the suspending portion 31, the tightening piece 22, the tightening piece 23, and the suspending portion 41 are fastened by tightening the nut 70 against the elastic force of the tightening pieces 22, 23.

When performing a pipe work using the pipe supporting tool 10, first, as shown in fig. 6, the operator lifts the band piece 40 so that the shaft portion 61 of the bolt 60 moves relatively from the abutting piece 43 side to the inclined piece 44 side in the elongated hole 41a, and brings the inclined piece 44 into abutment with the tightening piece 23 without bringing the abutting piece 43 into abutment, thereby bringing the band piece 40 into an open state with respect to the band piece 30. At this time, since the urging force (the rightward urging force in fig. 6) generated by the elasticity of the tightening piece 23 acts on the suspending portion 41, the operator pulls down the band piece 40 to move the shaft portion 61 relatively upward in the long hole 41a formed in the abutting piece 43, and then rotates the band piece 40 in the arrow a direction in fig. 6 against the urging force to move the shaft portion 61 relatively upward in the long hole 41a formed in the inclined piece 44.

Next, as shown in fig. 7, the operator temporarily sets the pipe P by inserting the pipe P into the pipe supporting tool 10 from between the band piece 30 and the band piece 40, and supporting a portion of the circumferential surface thereof including the lower end portion Pa by the bent portion 32a of the supporting portion 32.

Next, as shown in fig. 8, the operator turns the band piece 40 in the direction of arrow B to close it while following a trajectory opposite to that in the open state, and as shown in fig. 9, engages the engaging claw 32c with the engaged hole 42c by hooking the engaging claw 32c to the engaged hole 42c while being guided by the tapered surface 42e, thereby tightening the nut 70. When the tightening degree of the nut 70 to the bolt 60 is increased, a force in the arrow C direction acts on the belt piece 40, and therefore the engagement claw 32C and the engaged hole 42C are firmly engaged.

According to the pipe support tool 10 of the present embodiment, the suspending portion 41 is provided with the abutting piece 43 and the inclined piece 44, the abutting piece 43 abuts against the tightening piece 23 in a state where the suspending portion 41 is fastened together with the tightening pieces 22, 23 and the suspending portion 31, the inclined piece 44 extends upward from the upper portion of the abutting piece 43 in a direction away from the tightening piece 23, and the elongated hole 41a through which the shaft portion 61 of the bolt 60 is inserted is formed so as to extend from the abutting piece 43 to the inclined piece 44, so that during pipe work of the pipe P, the worker lifts the strap piece 40 so that the shaft portion 61 of the bolt 60 moves relatively in the elongated hole 41a from the abutting piece 43 side to the inclined piece 44 side, and brings the inclined piece 44 into abutment with the tightening piece 23, thereby directly putting the pipe P into the pipe support tool 10 in a state where the strap piece 40 is opened with respect to the strap piece 30. Therefore, the operator does not need to continuously press the tape piece 40 during the piping work. Further, since this work can be performed without particularly increasing the number of components and the number of assembly steps as compared with the conventional pipe support tool, the pipe support tool 10 can improve the workability of the pipe work with a simple structure.

Further, since the vertical dimension of the portion of the suspending portion 31 that abuts against the tightening piece 22 (the suspending portion 31 as a whole in this case) and the abutting piece 43 is the same h, the turnbuckle 20 can be prevented from being inclined when the fastening member 50 is fastened. That is, as shown in fig. 10, for example, when the dimension of the portion of the suspending portion 31 abutting the tightening piece 22 is larger by Δ h than the dimension of the abutting piece 43, the force of the fastening member 50 acts more widely on the tightening piece 22 than on the tightening piece 23 to tilt the turnbuckle 20 in the clockwise direction, but if the dimension of the portion of the suspending portion 31 abutting the tightening piece 22 and the dimension of the abutting piece 43 are the same or substantially the same as in the present embodiment, the tightening pieces 22, 23 receive the force from the left and right sides similarly, and such tilting is suppressed.

Since the retaining portion 61a is provided in the shaft portion 61 of the bolt 60, the thread surface of the retaining portion 61a is irregularly processed to retain the nut 70, and even if the nut 70 is loosened to the retaining portion 61a, the elastic deformation of the tightening pieces 22 and 23 with respect to the base portion 21 is maintained, so that the nut 70 is prevented from being removed, and in a state where the inclined piece 44 is brought into contact with the tightening piece 23 and the band piece 40 is opened with respect to the band piece 30 (at the time of temporary construction), elastic force is applied from the tightening piece 22 to the band piece 30 and from the tightening piece 23 to the band piece 40, respectively, whereby the play of the band piece 30 and the band piece 40 is suppressed, and the workability of the piping work is further improved.

Further, the belt piece 30 and the belt piece 40 are provided with the engaging claws 32c and the engaged holes 42c that engage with each other, and when the tightening of the nut 70 to the bolt 60 is increased, the engaging claws 32c and the engaged holes 42c are firmly engaged with each other, so that the loosening of the engagement of the belt piece 30 and the belt piece 40 can be suppressed.

Fig. 11 and 12 show modifications of the turnbuckle 20, the band piece 30, and the band piece 40.

In the turnbuckle 20, the retaining portion 22d faces the tightening piece 23, the retaining portion 23d faces the tightening piece 22, and stoppers 22f, 23f longer than the retaining portions 22d, 23d are provided below the retaining portions 22d, 23 d. When the turnbuckle 20 is attached to the suspension bolt B, the suspension bolt B is inserted into the turnbuckle 20 via the swivel nut 24, but if the insertion into the turnbuckle 20 becomes excessive as shown in fig. 13 (a), the elastic deformation of the tightening pieces 22 and 23 is inhibited. However, since the stoppers 22f and 23f prevent this excessive insertion as shown in fig. 13 (B), the elastic deformation of the tightening pieces 22 and 23 is prevented from being hindered by the suspension bolt B and hindering the pipe work.

As shown in fig. 14, the belt piece 30 is provided with a pair of regulating claws 32d, 32d via an engaging claw 32 c. In the pipe work, in the temporarily fixed state before the nut 70 is completely tightened (the state before the tightening degree of the nut 70 with respect to the bolt 60 is increased in fig. 9), the worker moves the pipe P in order to adjust the position of the pipe P, and the band pieces 30 and 40 sometimes collide and move in accordance therewith, but as shown in fig. 15, even if the band piece 40 moves in the arrow D direction with respect to the band piece 30 and tries to shift in the direction of engagement and disengagement of the engagement claw 32c and the engaged hole 42c, the restricting claw 32D provided in the supporting portion 32 abuts against the bent portion 42D and restricts the movement of the supporting portion 42 in the direction of engagement and disengagement thereof, so that the engagement and disengagement can be prevented during the adjustment of the pipe position.

The strap piece 40 is provided with a recess 41b for accommodating a part of the nut 70 in a temporarily fixed state at a position of a lower end of the elongated hole 41 a. In order for the worker to move the pipe P to adjust the position of the pipe P in the temporarily fixed state, as shown in fig. 16, even if the strap piece 40 moves in the direction of the arrow E relative to the strap piece 30 and is displaced vertically, the nut 70 accommodated in the recess 41b is caught by the recess 41b, and the vertical displacement is suppressed, so that the workability of the pipe work can be further improved.

The embodiments for carrying out the present invention have been described above as examples, but the embodiments of the present invention are not limited to the above-described embodiments, and may be appropriately changed or the like within a range not departing from the gist of the present invention.

For example, in the above embodiment, the engaging claws 32c are provided on the belt piece 30 and the engaged holes 42c are provided on the belt piece 40, but the engaging form is not limited to this, and it is needless to say that the engaged holes may be provided on the belt piece 30 and the engaging claws may be provided on the belt piece 40.

In the above embodiment, the shaft portion 61 of the bolt 60 is provided with the retaining portion 61a, and this retaining portion may be provided not on the bolt but on the nut, and the shape, forming position, and number of the restricting claws 32d are not limited to those described above, and may not be claw-shaped as in the restricting portion 32e shown in fig. 17, for example.
