Detailed Description

The structure of the stable installation type suspended ceiling system applying the technical scheme of the invention is further explained by combining the attached drawings.

As shown in fig. 1, 2 and 3, a novel stable ceiling system includes a stable ceiling structure, specifically including a main beam 1, and when viewed from a cross section, the main beam 1 includes a main beam base 11 for connecting to a suspension rod 4 and a first decoration material joint portion 12 extending from the main beam base 11, the first decoration material joint portion 12 is used for supporting a ceiling decoration material, in this embodiment, the ceiling decoration material is a decoration panel 2, and a panel edge of the decoration panel 2 is supported on the first decoration material joint portion 12. A main beam connection slot 110 with a downward notch is also arranged on the main beam base 11. For the sake of convenience of distinction from the girder connection socket to be mentioned below, the girder connection socket 110 is named a third girder connection socket 110. The third main beam connection slot 110 is located on the first decorator coupler 12. The decorative panel is characterized by further comprising a positioning spring piece 3, wherein the positioning spring piece 3 is used for enabling the head end 311 to be combined with the third main beam connecting slot 110 and enabling the tail end 321 to elastically press against the decorative panel 2 in the installation state, and elastic compression deformation is generated in the vertical direction under the compression action of the third main beam connecting slot 110 and the decorative panel 2, so that downward pressing acting force for fixing the decorative panel 2 on the first decorative material combining part 12 is formed. The third main beam connection slot 110 forms the spring piece combining portion for combining with the head end 311 of the positioning spring piece 3.

Wherein a third main beam connection slot 110 with a downward-arranged notch is further provided on the main beam base 11, and the above-mentioned feature defines that in the ceiling system, the notch of the third main beam connection slot 110 is arranged toward the ground. Thus, the head end 311 of the positioning spring plate 3 needs to be inserted into the third main beam connection slot 110 from bottom to top. When the head end 311 of the positioning spring piece 3 is inserted into the third main beam connecting slot 110, the head end 311 of the positioning spring piece 3 is elastically compressed and deformed to have a tendency of extending upward, so that the head end 311 can approach the bottom 1102 of the third main beam connecting slot 110 as much as possible and cannot easily get over the slot sidewall 1101 of the third main beam connecting slot 110 to be separated from the third main beam connecting slot 110.

The positioning spring pieces 3 are elastically compressible and deformable in the vertical direction under the compression action of the third main beam connecting slot 110 and the decorative panel 2, that is, the positioning spring pieces 3 are provided with an elastic structure capable of being appropriately expanded and contracted in the vertical direction, and the amount of expansion and contraction in the vertical direction can be flexibly adjusted in accordance with the vertical distance between the third main beam connecting slot 110 and the decorative panel 2 supported on the first decorative joint 12. Specifically, as shown in fig. 3, the positioning spring plate 3 is a substantially zigzag sheet metal component, and includes an upper elastic leg 31, a lower elastic leg 32, and a connecting arm 33 connected between the upper elastic leg 31 and the lower elastic leg 32, where the upper elastic leg 31 includes a head end 311 for being combined to the third main beam connecting slot 110, and a bent portion 312 disposed between the head end 311 and the connecting arm 33, and the bent portion 312 is used for being pressed by a hand to drive the head end 311 of the upper elastic leg 31 to move down so as to be combined to the third main beam connecting slot 110; the lower elastic support leg 32 is used for transversely and flatly leaning on the decoration panel 2 to provide stable support for the positioning spring piece 3. According to the above technical solution, in the process of installing the ceiling system, the plate edge of the decorative panel 2 is firstly supported on the first decorative material combining portion 12, then the lower elastic support leg 32 of the positioning spring piece 3 is placed on the decorative panel 2, and the hand applies a downward pressure to the upper elastic support leg 31 by pressing the bending portion 312 downward to make the positioning spring piece 3 generate compressive elastic deformation so that the head end 311 moves downward and is inserted into the third main beam connecting slot 110. The lower elastic legs 32 are stressed and deformed to be transversely and flatly leaned on the decorative panel 2 when the bending part 312 is pressed down by human hands, so that stable support is provided for the positioning spring pieces 3. Of course, in other embodiments, the lower spring leg 32 may already lie transversely flat against the trim panel 2 before being stressed.

According to the above technical solution, firstly, since the notch of the third main beam connecting slot 110 is arranged downward, and the positioning spring piece 3 is matched with an elastic structure which properly extends and contracts in the vertical direction, the head end 311 of the positioning spring piece 3 can be stabilized by the third main beam connecting slot 110, and the head end 311 is prevented from easily separating from the third main beam connecting slot 110 to damage the fixing effect of the positioning spring piece 3 on the decorative panel 2. Therefore, the positioning structure of the positioning spring piece 3 is simple and reliable. Secondly, because the positioning spring pieces 3 can be elastically compressed and deformed in the vertical direction under the compression action of the third main beam connecting slot 110 and the decoration panel 2, this is advantageous in view of the instability of the vertical distance between the third main beam attachment slot 110 and the decorative panel 2 supported by the first decorative material joining portion 12 due to the dimensional errors such as the dimensional errors in the manufacture of the third main beam attachment slot 110, the dimensional errors in the manufacture of the decorative panel 2, and the dimensional errors in the manufacture of the first decorative material joining portion 12, the positioning spring pieces 3 can reliably press and fix the decoration panel 2 on the first decoration material combination part 12, so that the stability of the decoration panel 2 is optimized, and the requirement on the manufacturing precision of the suspended ceiling main beam 1 can be reduced.

According to the above technical solution, since the auxiliary positioning beam 8, the transition connection member 9 and the screw are combined together to randomly define the positioning position of the ceiling main beam 1 on the auxiliary positioning beam 8 and stabilize the horizontal position of the ceiling main beam 1, in this way, the horizontal position of the ceiling main beam 1 can be determined and defined by the auxiliary positioning beam 8 at the installation site, the auxiliary positioning beam 8 provides a horizontal positioning reference for the ceiling main beam 1, and the ceiling main beam 1 can be determined on any position on the auxiliary positioning beam 8, it can be seen that the position of the ceiling main beam 1 in the first axis direction is arbitrarily adjustable, so that the ceiling main beam 1 can be more easily adapted to the size and the installation position of the decoration panel 2 to flexibly adjust the position thereof, especially when the decoration panel 2 has strict matching dimension requirements with the adjacent ceiling main beam 1, the manufacturer can cut the decorative panel 2 into specific specifications according to design requirements in advance in a factory, the space size between the adjacent suspended ceiling main beams 1 does not need to be measured on site one by one, and the decorative panel 2 is cut according to the space size, so that the field installation efficiency is greatly improved, and the requirement on the precision of the matching size of the decorative panel 2 is favorably reduced; secondly, the auxiliary positioning beams 8, the transition connecting pieces 9 and the screws are combined to form a stable space between the front and rear adjacent ceiling main beams 1, so that the decoration panel 2 is stable, and a stable ceiling framework system is formed by the auxiliary positioning beams 8, so that the ceiling main beams 1 and the auxiliary positioning beams 8 can be firstly formed into the ceiling framework system on the ground and then integrally hoisted to a roof under the condition that the field space allows, and the installation is more convenient; in addition, first support arm 91a can connect and fix a position through screw 95 on the furred ceiling girder 1, and second support arm 92 can connect and fix a position through screw 94 connection structure on the auxiliary positioning roof beam 8 makes furred ceiling girder 1 with form firm relation of connection between the auxiliary positioning roof beam 8, be favorable to promoting furred ceiling system's shock resistance, be particularly useful for high-rise building, the many areas of earthquake, the many occasions that the molding of adorning in the big plane furred ceiling changes etc..

As for the connection structure between the suspended ceiling main beam, the auxiliary positioning beam and the transition connecting piece, another technical scheme can be adopted. As shown in fig. 13 and 14, a threaded hole 910a is provided on the first arm 91a of the transition piece 9a, and the first arm 91a is inserted into a main beam connection slot (not shown) of the main ceiling beam 1 and is connected and positioned to any position of the main ceiling beam 1 in the first axial direction by a structure that a screw 95a is screwed into the threaded hole 910 a. In this way, the transition piece 9a can adjust the position of the auxiliary positioning beam 8 in the first axial direction by sliding the first arm 91a in the main beam connection slot when the screw 95a is loosened, and the ceiling main beam 1 is still in the connection relationship with the auxiliary positioning beam 8 without being separated during the whole process, so that the bearing force of the hand on the ceiling main beam 1 during the adjustment process can be reduced. The second arm 92a is provided with a through hole 920a, and the second arm 92 is tightened, connected and positioned to any position of the auxiliary positioning beam 8 in the second axial direction by passing a screw 94a with a screw head or a connecting nut, which can be engaged with the auxiliary beam connecting slot 80, through the through hole 920 a. Thus, when the ceiling main beam 1 needs to be disassembled, the ceiling main beam 1 can be conveniently disassembled by loosening the screws 94 a.

As shown in fig. 8 and 15, a spacer beam 100 is further disposed in a direction perpendicular to the first axial direction (of course, in other embodiments, the spacer beam 100 is further disposed in a direction inclined to the first axial direction), the spacer beam 100 has a profile shape including second decorative material coupling portions (1001, 1002) disposed left and right, the second decorative material coupling portions (1001, 1002) are used to couple the decorative panel 2, and front and rear ends of the spacer beam 100 are respectively lap-joined to the first decorative material coupling portions 12 of the ceiling main beams 1 adjacent in the front and rear direction. According to the above technical solution, firstly, the partition beam 100 is primarily positioned on the first decorative material combining part 12 of the ceiling main beam 1 adjacent in front and back by means of lap joint, for this reason, in the case that the first decorative material combining part 12 extends along the first axial direction, the position of the partition beam 100 in the first axial direction can be set arbitrarily, so that the partition beam can be arranged by adapting to decorative panels 2 with different dimensions or installation positions; secondly, the spacer bar 100 can be further positioned by means of the trim panel 2 arranged adjacently and bonded to the second trim material bonding portion (1001, 1002), so that the mounting and dismounting of the spacer bar 100 is also very convenient.
