Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Example 1:

a dry hook is shown in figure 1-2, and the dry hook 1 is hung on a horizontal keel 2 and used for fixing the upper end and the lower end of a wall brick 6. The horizontal keel 2 is formed by bending a plate and has a right-angle bending structure. The horizontal keel 2 comprises a horizontal plate 21 and a vertical plate 22, the plate surface of the horizontal plate 21 is parallel to the horizontal plane, the plate surface of the vertical plate 22 is parallel to the vertical plane, and the front surface of the vertical plate 22 is a supporting surface. The horizontal plate 21 is provided with at least two long slotted holes, and the long slotted holes are used for adjusting the distance between the wall bricks 6 and the wall body 7. In the construction, the horizontal keel 2 can be replaced by an angle steel section.

In this embodiment, the wall brick 6 is a ceramic brick for an outer wall, and the brick body is thick and has a maximum thickness of about 4 cm. The front surface of the external wall tile 6 has a convex-concave shape, and the surface is glazed. In order to reduce weight and facilitate dry hanging, three through clamping grooves 61 are formed in the upper end face and the lower end face of the outer wall brick 6, and the distance between each clamping groove 61 and the back face of the outer wall brick 6 is about 1 cm.

As shown in fig. 3, the dry hook 1 is integrally formed by a stainless steel plate with a thickness of 0.7 mm. The dry hook 1 is divided into a hook part 12, a back face supporting part 13, a bottom face supporting part 14, a lower pressing part 15 and an upper pressing part 16 from head to tail in sequence. Before the exterior wall tile 6 is dry-hung, the included angle between the bottom surface supporting part 14 and the back surface supporting part 13 is 85 degrees, and the included angle between the bottom surface supporting part 14 and the lower pressing part 15 is 75 degrees.

As shown in fig. 4, the hooking part 12 is a section caught at the upper end of the vertical plate 22 of the horizontal keel 2, and the hooking part 12 has a right-angled hook structure, and the hooking part 12 is caught at the upper end of the vertical plate 22 when the exterior wall tile 6 is dry-hung.

The back support part 13 means a section extending downward and attached to a support surface of the vertical plate 22 of the horizontal keel 2, and the back support part 13 is used to support the back surface of the upper outer wall tile 6.

The bottom surface support portion 14 refers to a section extending toward the front surface of the outer wall tile 6 by a length greater than the distance from the receiving groove 61 of the lower outer wall tile 6 to the back surface thereof. The bottom surface supporting part 14 is used for supporting the bottom surface of the upper layer outer wall brick 6, after the weight of the upper layer outer wall brick 6 is borne, the bottom surface supporting part 14 can bend downwards, the included angle between the bottom surface supporting part 14 and the back surface supporting part 13 is changed from 85 degrees to 88 degrees, and the bottom surface supporting part 14 is close to the horizontal state. It should be noted that the variation of the included angle between the bottom support portion 14 and the back support portion 13 is related to the plate thickness of the dry hook and the weight of the exterior wall tile 6, and the dry hook with larger plate thickness or plate width should be selected for the exterior wall tile 6 with larger weight to ensure the proper support strength and variation of the included angle.

The lower pressing part 15 is a section which extends downwards and slantways towards the wall 7 and extends into the clamping groove 61 of the lower layer external wall tile 6, and the lower pressing part 15 is used for pressing the lower layer external wall tile 6 towards the wall 7. The included angle between the bottom surface supporting part 14 and the lower pressing part 15 in the free state is 75 degrees, when the dry hook 1 is installed, a certain pre-pressure is applied to the side, facing the wall body 7, of the outer wall brick 6 on the lower layer by the lower pressing part 15, and the included angle between the bottom surface supporting part 14 and the lower pressing part 15 is increased accordingly. When the upper outer wall brick 6 is laid, the bottom supporting part 14 bends downwards due to the weight of the upper outer wall brick 6, and drives the lower pressing part 15 to further press the lower outer wall brick 6 towards the wall 7 side, so that the back of the lower outer wall brick 6 is tightly attached to the supporting surface of the vertical plate 22 of the horizontal keel 2. At this time, the angle between the bottom surface supporting portion 14 and the lower pressing portion 15 is further increased.

The upper pressing part 16 is a section which is bent upwards and extends into the clamping groove 61 of the upper outer wall brick 6, and the upper pressing part 16 is used for pressing the upper outer wall brick 6 towards the wall 7 side. The distance between the upper pressing portion 16 and the back support portion 13 is already close to 1 cm before the upper exterior wall tile 6 is put in. After the upper layer outer wall brick 6 is put in, because the included angle between the bottom surface supporting part 14 and the lower pressing part 15 is greatly increased, the bottom surface supporting part 14 takes the contact point between the lower pressing part 15 and the lower layer outer wall brick 6 as a fulcrum, and drives the upper pressing part 16 to rotate towards the wall body 7 side. The lever enlarges the moving stroke of the upper pressing part 16 to the wall body 7 side, so that the upper pressing part 16 can be reliably pressed on the outer wall brick 6 on the upper layer, and the back surface of the outer wall brick 6 on the upper layer is pressed on the supporting surface of the vertical plate 22 of the horizontal keel 2.

According to the structure, the dry hook 1 skillfully utilizes the gravity of the external wall bricks 6 to ensure that the bottom surface supporting part 14, the lower pressing part 15 and the upper pressing part 16 are pressed and positioned in a linkage manner, so that the upper and lower external wall bricks 6 are positioned and fixed.

In the existing dry-hanging construction process, no matter the external wall tiles 6 are dry-hung or the internal and external wall tiles 6 are dry-hung, each external wall tile 6 needs two or four such hanging pieces according to the width, and the adjustment of the hanging pieces only has an effect on the external wall tile 6 and has no effect on the adjacent external wall tiles 6. Therefore, the mounting and the adjustment of the hanging pieces are the most important in the whole dry hanging construction, and the workload is the largest. In order to solve the defects of the existing dry-hanging construction process, the invention also improves the dry-hanging construction process.

A dry-hanging construction process is used for dry hanging of external wall tiles: the method comprises the following steps:

s1: first, the plate-like member 5 is embedded in the wall 7. The angle code 4 is firstly installed on a long slotted hole of the horizontal keel 2 by using the bolt and nut connection pair 3, then the angle code 4 is fixed on the plate-shaped member 5 by means of a laser level meter, the connection position of the horizontal keel 2 on the angle code 4 is adjusted, the supporting surfaces of the vertical plates 22 of each horizontal keel are coplanar, and the upper end surfaces of the vertical plates 22 are parallel and equidistant. It should be noted that the corner brace 4 may also be directly fixed to the wall 7 by expansion bolts. In order to prevent rusting and corrosion, the angle brace 4, the horizontal keel 2 and the used bolt and nut are all galvanized pieces.

S2: hanging dry hooks 1 on a vertical plate 22 of the horizontal keel at intervals, and then inserting a clamping groove 61 at the lower end of the external wall tile 6 into the dry hooks 1 to enable the bottom surface supporting part 14 to support the lower end surface of the external wall tile 6; the upper layer of horizontal keel 2 is hung with the dry hook 1 at intervals, and the lower pressing part of the dry hook 1 is inserted into the clamping groove 61 at the upper end of the external tile 6;

s3: s2 is repeated and the lateral gap of the exterior wall tile 6 is adjusted. After each layer of the external wall bricks 6 is laid, the laying surface of the external wall bricks 6 and the gaps of brick joints are adjusted, and then the dry hanging pieces 1 clamped at the upper ends of the external wall bricks 6 are fixed by spot welding. And then paving the external wall bricks 6 layer by layer from bottom to top to finish the paving of the external wall bricks 6.

The adjustment of the paving surface and the brick joint gap refers to that thinning filler strips are additionally arranged between each bottom surface supporting part 14 and the lower end surface of the external wall brick 6 so as to adjust the levelness and the uniformity of the brick joint of the external wall brick 6; the thinning filler strip is added between each back support part 13 or support surface and the back of the external wall tile, in order to make the front surface of the external wall tile 6 and the laying surface coplanar. Obviously, the small adjustment is beneficial to eliminating the adverse effect of the external wall tile 6 or the dry hook 1 on the laying due to the manufacturing error of the external wall tile or the dry hook.

Compared with the existing construction process, the construction process does not need to adjust the hanging piece and glue application for fixation, and has great superiority in operation and environmental protection. Because this dry couple has the characteristics that the upper bracket pushed down, can fix a position and fix upper and lower outer wall brick 6 simultaneously, consequently every outer wall brick 6 only needs one or two dry couples on average alright completion outer wall brick 6 in the horizontal direction and the ascending location of vertical direction with fixed. Compared with the prior construction process, the use amount and construction amount of the dry hook are reduced by times.

As shown in fig. 4, due to the bottom support 14, the wall tiles 6 in the upper row are protruded by a wall thickness of 0.7mm more than the wall tiles 6 in the lower row. Thus, each row of the external wall bricks 6 has a slight inclination angle inclined towards the wall 7, and the inclination angle enables the front surface of the external wall bricks 6 to incline towards the wall 7, so that the external wall bricks have the function of a sloping surface eave.

As shown in fig. 5, when the raindrops 8 flow from the upper portion to the lower portion of the exterior wall tiles 6, the raindrops 8 are made to make a parabolic motion along the extension direction of the slope by inertia, so as to prevent or reduce the raindrops 8 from flowing to the next row of exterior wall tiles 6. For the external wall tile 6 with the convex-concave shape, the slight inclination angle does not cause influence on vision, but the problem of water feathering shadow is greatly improved.

The construction process can obtain that:

1. the key control points that have the greatest impact on the appearance of the exterior wall tile 6 are the coplanarity of the support surfaces of the horizontal keels and the parallelism and equal distance of the upper end surfaces of the vertical plates. This work is very easily realized through the laser level meter before laying outer wall brick 6, just need not consider the regulation and the installation problem of pendant when laying outer wall brick 6 again, only need from up from down lay outer wall brick 6 by layer, consequently the efficiency of construction obtains improving by a wide margin.

2. The transverse gap of each external tile 6 is determined by the dry hook, and the horizontal and uniform transverse gap can be ensured as long as the dry hook has uniform shape and size, so that the construction progress and quality are ensured.

3. The mounting structure of the dry hook enables each row of outer wall bricks 6 to have a tiny inclined angle inclined towards the wall side, skillfully avoids or reduces the immersion of rainwater on the back of the outer wall bricks 6, and greatly improves the problem of water feathering shadow.

Example 2:

a dry hook according to embodiment 1, unlike embodiment 1, the dry hook 1 according to the present embodiment has the following two differences as shown in fig. 6.

Difference point 1: before the exterior wall tile 6 is dry-hung, the included angle of the hook part 12 is 75 degrees. A tip end guide portion 11 is connected to a tip end of the hook portion 12, and the tip end guide portion 11 extends obliquely downward toward the wall body 7. The head end guide portion 11 functions to guide and spread the hook portion 12, and facilitates the engagement of the hook portion 12 with the vertical plate 22. When clamping, the included angle of the clamping hook part 12 is increased from 75 degrees to 90 degrees, and the vertical plate 22 is clamped in the horizontal direction. Compared with embodiment 1, the hook part 12 is clamped with the vertical plate 22 more firmly, and is not easy to shake.

Difference point 2: the rear end of the upper pressing part 16 is connected with a terminal guide part 17, and the terminal guide part 17 extends obliquely upwards towards the front side of the outer wall brick 6. The end guide portion 17 is used for guiding and opening the upper pressing portion 16, so that the upper outer wall brick 6 can be conveniently placed on the bottom surface supporting portion 14 from top to bottom to complete the positioning of the bottom of the upper outer wall brick 6. In example 1, the distance between the upper pressing portion 16 and the back support portion 13 is only approximately 1 cm and not less than 1 cm before the upper exterior wall tile 6 is placed, which may hinder the placement of the upper exterior wall tile 6. Due to the existence of the tail end guide part 17, the distance between the upper pressing part 16 and the back supporting part 13 can be smaller than 1 cm, so that pre-pressure towards the wall 7 side can be applied to the upper outer wall brick 6 when the upper outer wall brick 6 is put in, and the total pressing force to the upper outer wall brick 6 is increased.

Example 3:

unlike embodiment 2, the dry hook 1 of the present embodiment is different from embodiment 2 in the following points.

As shown in fig. 7, an angular flap 9 is connected to the dry hook 1, and the angular flap 9 is as thick as the dry hook 1. One outer plate surface of the angular folded plate 9 is spot-welded on the lower plate surface of the bottom surface supporting part 14, and the other outer plate surface is coplanar with the plate surface of the back surface supporting part 13 facing the wall body 7.

As can be seen from fig. 8, the supporting strength of the bottom supporting portion 13 to the interior wall brick 10 is enhanced by the one side plate body of the angular folded plate 9 connected with the bottom supporting portion 14, and the other side plate body of the angular folded plate 9 flattens the back of the interior wall brick 10, so as to ensure the perpendicularity of the interior wall brick 10 and the coplanarity with the laying surface. Obviously, the dry hook is suitable for laying indoor wall bricks, and the construction process for laying the indoor wall bricks is basically the same as that in the embodiment 1, and the description is not repeated.

It is worth pointing out that the existing inner wall brick 10 is thin, and there is no prefabricated slot when leaving factory, and it needs to be slotted on site by angle grinder during construction. The non-uniformity of the slotting position is one of the reasons that the existing pendant can only adjust one wall brick but can not adjust the upper layer or the lower layer of the wall brick. Because the upper pressing part 16 and the lower pressing part 15 of the dry hook have elastic force for pressing the wall bricks to the side of the wall 7, the interference that the slotting positions are not uniform can be eliminated, and the wall bricks on the upper layer and the lower layer can be simultaneously positioned and pressed.

The present invention is not described in detail in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
