Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to a building waterproof wall structure. Background Art

[0002] In the construction field, the waterproof performance of walls is crucial for the durability and living comfort of buildings. However, traditional wall structures usually have some deficiencies in terms of waterproofing. For example, the waterproof layer is prone to aging and cracking, resulting in rainwater penetration, which affects the stability of the wall structure and the indoor environment. During use, moisture easily seeps in from both sides of the wall, affecting the service life of the wall.

[0003] Therefore, developing a new type of waterproof wall structure to improve the waterproof performance of walls has become an urgent problem to be solved in the construction industry. Utility Model Content

[0004] In order to improve the waterproof performance and service life of the wall surface, this application provides a building waterproof wall structure.

[0005] The building waterproof wall structure provided by this application adopts the following technical solution:

The connecting component is arranged between two adjacent wall bodies. The connecting component includes a butyl tape and an anti-cracking member. The butyl tape is adhered to the joint of the two cement fiber lining boards in the two wall bodies. The butyl tape is arranged on the side of the cement fiber lining board close to the cement fiber board with a finish layer. The anti-cracking member is connected between the two cement fiber lining boards in the two wall bodies.

[0007] By adopting the above technical solution, the butyl waterproof tape is bonded between two adjacent cement fiber lining boards, filling the gap between the cement fiber lining boards, which helps to improve the waterproof performance of the wall. The anti-cracking member is connected between two adjacent cement fiber lining boards, which helps to reduce the possibility of the separation of the cement fiber lining boards. Through the mutual cooperation of the wall body and the connecting component, the waterproof performance and service life of the wall surface can be improved.

[0008] Optionally, the edge of the butyl tape is coated with a polymer waterproof material, and the polymer waterproof material is jointly coated at the joint of the butyl waterproof tape and the cement fiber lining board.

[0009] By adopting the above technical solution, the polymer waterproof material forms a waterproof film layer at the edge of the butyl tape, filling the gap between the butyl tape and the cement fiber liner, and also having good stretchability, which helps to further improve the waterproof performance of the wall.

[0010] Optionally, two parallel vertical rectangular steel pipes are arranged between the composite interior wall panel and the cement fiber liner. The exterior of the vertical rectangular steel pipes is coated with fireproof paint. There is a gap between the two vertical rectangular steel pipes. The fireproof rock wool layer is arranged between the two vertical rectangular steel pipes. A wire mesh layer is connected between the two vertical rectangular steel pipes, and the wire mesh layer is arranged on one side of the two vertical rectangular steel pipes close to the composite interior wall panel.

[0011] By adopting the above technical solution, the vertical rectangular steel pipes support the wall, improving the structural strength of the wall, and the wire mesh layer supports and positions the fireproof rock wool layer.

[0012] Optionally, the crack prevention member includes an elastic plate and connecting parts. The elastic plate is arranged in an arc shape. One connecting part is arranged at each end of the elastic plate in the length direction.

[0014] Optionally, a relief groove is formed on one side of the cement fiber board with finish close to the cement fiber liner, and the relief groove is arranged corresponding to the shape and position of the crack prevention member.

[0015] By adopting the above technical solution, the arrangement of the relief groove enables the cement fiber liner to be kept in contact with the cement fiber board with finish, reducing the possibility of protrusions and hollowing on the wall surface.

[0016] Optionally, a waterproof and breathable membrane is laid between the fireproof rock wool layer and the cement fiber liner.

[0017] By adopting the above technical solution, the arrangement of the waterproof and breathable membrane reduces the possibility of moisture seeping into the interior of the wall from the outside, helping to improve the waterproof property of the wall.

[0018] Optionally, a waterproof and airtight membrane is laid between the wire mesh layer and the fireproof rock wool layer.

[0030] Refer to Figure 1, a building waterproof wall structure includes a wall body and a connecting component. The wall body includes a composite inner wall panel 1, a fireproof rock wool layer 2, a cement fiber liner 3, and a cement fiber board with finish 4 arranged in sequence from inside to outside. A plurality of cement fiber liners 3 are laid in the same plane. Two vertical rectangular steel pipes 5 are arranged in parallel between the composite inner wall panel 1 and the cement fiber liner 3, and a fireproof material 6 is thickly coated on the outside of the vertical rectangular steel pipes 5. There is a gap between the two vertical rectangular steel pipes 5, and the fireproof rock wool layer 2 is filled between the two vertical rectangular steel pipes 5.

[0031] Refer to Figure 1 and Figure 2 , a wire mesh layer 13 is connected between the two vertical rectangular steel pipes 5. The wire mesh layer 13 is arranged on the side of the vertical rectangular steel pipes 5 close to the composite inner wall panel 1, and a waterproof and airtight membrane 7 is laid between the wire mesh layer 13 and the fireproof rock wool layer 2. A waterproof and breathable membrane 8 is laid between the two vertical rectangular steel pipes 5, and the waterproof and breathable membrane 8 is clamped between the fireproof rock wool layer 2 and the cement fiber liner 3.

[0032] Refer to Figure 1 and Figure 2 , the connecting component includes a butyl tape 9 and a crack prevention member 10. The butyl tape 9 is bonded to the joints of several adjacent cement fiber liners 3. The butyl tape 9 is simultaneously bonded to two adjacent cement fiber liners 3. The butyl tape 9 is arranged on the side of the cement fiber liner 3 close to the cement fiber board with finish 4. Polymer waterproof materials 14 are coated on the edges at both ends in the width direction of the butyl tape 9. The polymer waterproof materials 14 are jointly coated on the butyl tape 9 and the cement fiber liner 3. The polymer waterproof materials 14 used in the embodiments of the present application include, but are not limited to, materials such as polyacrylate emulsion and ethylene-vinyl acetate copolymer emulsion.

[0033] Refer to Figure 1 and Figure 2 , several crack prevention members 10 are arranged between two adjacent cement fiber liners 3. The crack prevention member 10 includes an elastic plate 101 and connecting parts 102. The elastic plate 101 is arc-shaped and made of an elastic material. One connecting part 102 is arranged at each end in the length direction of the elastic plate 101. Connecting holes 31 for the connecting parts 102 to pass through are opened on the edges of the cement fiber liner 3. The elastic plate 101 is arranged on the side of two adjacent cement fiber liners 3 close to the cement fiber board with finish 4. The two connecting parts 102 at both ends of the elastic plate 101 correspond to the connecting holes 31 on the two adjacent cement fiber liners 3 one by one. The connecting parts 102 pass through the cement fiber liner 3 through the connecting holes 31 and are bent to an angle that fits the cement fiber liner 3.

[0034] Refer to Figure 1 and Figure 2, a relief groove 41 corresponding to the elastic plate 101 is provided on one side of the decorative cement fiber board 4 close to the cement limiting lining board. Structural weatherproof glue 12 is filled between adjacent decorative cement fiber boards 4. A foam rod 11 is provided on the outer edge of the decorative cement fiber board 4 on the outermost circumference, and structural weatherproof glue 12 is bonded between the foam rod 11 and the decorative cement fiber board 4.

[0035] Refer to Figure 1 , the fireproof rock wool layer 2 is arranged between the steel wire mesh layer 13, the cement fiber lining board 3 and the two vertical rectangular steel pipes 5. The steel wire mesh layer 13, the cement fiber lining board 3 and the two vertical rectangular steel pipes 5 support and protect the fireproof rock wool layer 2, which helps to improve the overall strength of the wall structure. The setting of the steel wire mesh layer 13, on the one hand, limits and supports the fireproof rock wool layer 2, and on the other hand, improves the tensile strength of the waterproof and airtight membrane 7, reducing the possibility of cracking caused by wall settlement or temperature change. The waterproof and airtight membrane 7 and the waterproof and breathable membrane 8 are arranged on the opposite sides of the fireproof rock wool layer 2, reducing the possibility of external moisture entering the fireproof rock wool layer 2 and affecting its performance.

[0036] Refer to Figure 1 and Figure 2 , the butyl tape 9 is bonded between the two cement fiber lining boards 3 to achieve waterproof treatment of the gap, reducing the possibility of moisture seeping into the wall along the gap. The polymer waterproof material 14 is evenly coated on the edge of the butyl tape 9 and forms a waterproof film layer on it, covering the tiny gaps and pores on the wall, further effectively preventing water penetration. In addition, the polymer waterproof coating has excellent ductility and aging resistance, and has the characteristics of combining rigidity and flexibility, and can stably fit on the surface of the cement fiber lining board 3 when the cement fiber lining board 3 undergoes minor deformation to achieve its waterproof performance.

[0037] Refer to Figure 1 and Figure 2 , the crack prevention member 10 is connected between two adjacent cement fiber lining boards 3 through the connecting parts 102 at both ends, reducing the possibility of separation of the cement fiber lining board 3. The setting of the elastic plate 101 enables the crack prevention member 10 not to be damaged when the cement fiber lining board 3 deforms at different temperatures. The setting of the relief groove 41 on the decorative cement fiber board 4 enables the decorative cement fiber board 4 to fit flatly with the cement fiber lining board 3, reducing the possibility of wall hollowing. The setting of the foam rod 11 and the structural weatherproof glue 12 realizes the sealing of the edge of the decorative cement lining board, which helps to further improve the waterproof performance of the wall.

[0038] In the embodiment of the present application, the implementation principle of a building waterproof wall structure is as follows: on the one hand, the wire mesh layer 13 limits and supports the fireproof rock wool layer 2, and on the other hand, it improves the tensile strength of the waterproof and vapor barrier film 7. The waterproof and vapor barrier film 7 and the waterproof and breathable film 8 reduce the possibility of external moisture entering the fireproof rock wool layer 2 and affecting its performance. The butyl tape 9 realizes the waterproof treatment of the gap. The polymer waterproof material 14 is evenly coated on the edge of the butyl tape 9 and forms a waterproof film layer thereon, further effectively preventing water penetration. The crack prevention member 10 is connected between two adjacent cement fiber liners 3 through the connecting parts 102 at both ends, reducing the possibility of separation of the cement fiber liners 3.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
