Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an exterior wall anti-cracking and anti-leakage structure. Background Art

[0002] In the construction industry, the crack resistance and waterproofness of exterior walls are key factors in ensuring building quality and extending the service life of buildings. Traditional exterior wall structures are prone to cracks under the influence of natural factors such as temperature changes, humidity changes and wind loads, leading to leakage problems, which not only affects the beauty and usability of the building, but may also pose a threat to the safety of the building structure.

[0003] At present, waterproofing of building exterior walls is mainly achieved by applying a layer of waterproof mortar on the outside of the building exterior wall. However, in actual use, the waterproof structure on the building exterior wall is still easily affected by the external environment and cracks and falls off, which in turn causes leakage of the building exterior wall, making the use of the building exterior wall less safe. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an external wall anti-cracking and anti-leakage structure which can significantly improve the anti-cracking and anti-leakage performance of the building external wall in view of the current status of the existing technology.

[0005] The present invention is achieved through the following technical solution: The present invention proposes an anti-cracking and anti-leakage structure for an exterior wall, comprising a base wall, a mortar leveling layer is laid on the outside of the base wall, an insulation board is installed on the outside of the mortar leveling layer, an anti-cracking waterproof layer is installed on the outside of the insulation board, and a finishing layer is also laid on the outside of the anti-cracking waterproof layer, wherein the anti-cracking waterproof layer comprises an anti-cracking mortar layer 1 bonded to the outer wall of the insulation board, a reinforcement layer installed on the outside of the anti-cracking mortar layer 1, an anti-cracking mortar layer 2 installed on the outside of the reinforcement layer, and a waterproof membrane installed on the outside of the anti-cracking mortar layer 2.

[0006] By adopting the above technical solution, when the building exterior wall is in use, under the action of the anti-cracking mortar layer 1 and the anti-cracking mortar layer 2, the material's own expansion and contraction properties can be used to resist the expansion and cracking of the building exterior wall waterproof layer caused by changes in the external environmental temperature. At the same time, the reinforcement layer can be used to further increase the tensile strength of the anti-cracking waterproof layer, further resisting the cracking of the anti-cracking waterproof layer. Under the action of the waterproof membrane, the outside of the building exterior wall and the water vapor in the external environment can be completely blocked, avoiding the intrusion of water vapor into the building exterior wall and leakage, thereby making the building exterior wall have better anti-cracking and waterproof performance and safer and more reliable to use. The insulation board ensures the thermal insulation performance of the building exterior wall when in use, and at the same time, the design of the finishing layer can effectively ensure the aesthetics of the building exterior wall.

[0007] Furthermore, the reinforcement layer includes a steel mesh layer 1 bonded to the outer wall of the anti-cracking mortar layer 1, a steel mesh layer 2 bonded to the inner wall of the anti-cracking mortar layer 2, and an alkali-resistant glass fiber mesh cloth installed between the steel mesh layer 1 and the steel mesh layer 2.

[0008] By adopting the above technical solution, the steel mesh layer one, the steel mesh layer two and the alkali-resistant glass fiber mesh cloth all have good tensile properties, so under the action of the reinforcement layer, the crack resistance of the anti-cracking waterproof layer is guaranteed. Since the alkali-resistant glass fiber mesh cloth itself also has good acid and alkali corrosion resistance, the anti-cracking waterproof layer also has certain acid and alkali corrosion resistance.

[0009] Furthermore, the first steel mesh layer and the second steel mesh layer are both woven from steel wires, and the first steel mesh layer and the second steel mesh layer are both in contact with the alkali-resistant glass fiber mesh cloth.

[0010] By adopting the above technical solution, it is possible to ensure that the alkali-resistant glass fiber mesh cloth is reliably installed between the first steel mesh layer and the second steel mesh layer.

[0011] Furthermore, the first steel mesh layer is bonded to the first anti-cracking mortar layer, and the second steel mesh layer is bonded to the second anti-cracking mortar layer.

[0012] By adopting the above technical solution, the reliable installation and laying of the first and second steel mesh layers on the outside of the building exterior wall is ensured.

[0013] Furthermore, the waterproof roll is a waterproof roll made of polyethylene polypropylene, and a connecting component is arranged on the waterproof roll.

[0014] By adopting the above technical solution, the polyethylene polypropylene waterproof membrane has excellent crack resistance and waterproof properties, thereby effectively preventing external water vapor from invading the exterior walls of the building.

[0015] Furthermore, the connection assembly includes a limit bolt installed on the insulation board and a fixing nut installed on one end of the limit bolt facing away from the insulation board.

[0016] By adopting the above technical solution, the connecting assembly is mainly used to achieve reliable limited installation of the waterproof membrane during laying.

[0017] Furthermore, the limiting bolt passes through the insulation board and the anti-cracking waterproof layer, and the fixing nut is located on the outside of the waterproof membrane.

[0018] By adopting the above technical solution, when the fixing nut is tightened, the waterproof membrane can be reliably pressed against the outside of the second anti-cracking mortar layer under the compression action of the fixing nut, thereby achieving reliable positioning of the waterproof membrane after laying.

[0019] Furthermore, a countersunk hole is provided on the insulation board at the position of the limit bolt, the countersunk hole passes through the insulation board, and the size of the countersunk hole matches the size of the limit bolt.

[0020] By adopting the above technical solution, the countersunk hole can ensure that the limiting bolt can pass through easily.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The utility model installs the anti-cracking waterproof layer composed of the anti-cracking mortar layer 1, the anti-cracking mortar layer 2, the reinforcement layer and the waterproof membrane on the outer side of the insulation board of the building exterior wall. When the building exterior wall is in use, the anti-cracking performance and acid and alkali corrosion resistance of the anti-cracking waterproof layer can be effectively increased under the action of the reinforcement layer, the anti-cracking mortar layer 1 and the anti-cracking mortar layer 2. Moreover, the waterproof membrane can effectively block the external water vapor from invading the base wall, avoiding leakage. Therefore, the anti-cracking and anti-leakage performance of the building exterior wall is better when in use, and it is safer and more reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figure 1-Figure 3 As shown, an exterior wall anti-cracking and anti-leakage structure in this embodiment includes a base wall 1, a mortar leveling layer 2 is laid on the outside of the base wall 1, an insulation board 3 is installed on the outside of the insulation board 3, an anti-cracking waterproof layer 4 is installed on the outside of the insulation board 3, and a finishing layer 5 is also laid on the outside of the anti-cracking waterproof layer 4, wherein the anti-cracking waterproof layer 4 includes an anti-cracking mortar layer 1 401 bonded to the outer wall of the insulation board 3, a reinforcement layer 402 installed on the outside of the anti-cracking mortar layer 1 401, an anti-cracking mortar layer 2 403 installed on the outside of the reinforcement layer 402, and a waterproof membrane 404 installed on the outside of the anti-cracking mortar layer 2 403;

[0032] The embodiment of the present invention provides an exterior wall anti-cracking and anti-leakage structure that can significantly improve the anti-cracking and anti-leakage performance of the building exterior wall, thereby solving the problem that in the prior art, when waterproofing the building exterior wall, a layer of waterproof mortar is mainly applied to the outside of the building exterior wall to achieve the purpose of waterproofing the building exterior wall, but in actual use, the waterproof structure on the building exterior wall is still easily affected by the external environment and cracks and falls off, thereby causing leakage of the building exterior wall, making the building exterior wall less safe to use. The embodiment of the present invention is to solve the above problem The overall idea of ​​the problem is: an anti-cracking waterproof layer 4 composed of an anti-cracking mortar layer 1 401, an anti-cracking mortar layer 2 403, a reinforcement layer 402 and a waterproof roll 404 is installed on the outside of the insulation board 3 on the exterior wall of the building, so that when the exterior wall of the building is in use, it can not only effectively increase the crack resistance and acid and alkali corrosion resistance of the anti-cracking waterproof layer 4 under the action of the reinforcement layer 402, the anti-cracking mortar layer 1 401 and the anti-cracking mortar layer 2 403, but also can effectively block external water vapor from invading the base wall 1 under the action of the waterproof roll 404, thereby avoiding leakage.

[0033] like Figure 1-Figure 2 As shown, in this embodiment, the reinforcement layer 402 includes a steel mesh layer 1 4021 bonded to the outer wall of the anti-cracking mortar layer 1 401, a steel mesh layer 2 4023 bonded to the inner wall of the anti-cracking mortar layer 2 403, and an alkali-resistant glass fiber mesh cloth 4022 installed between the steel mesh layer 1 4021 and the steel mesh layer 2 4023.

[0034] As an embodiment, the steel mesh layer 1 4021, the steel mesh layer 2 4023 and the alkali-resistant glass fiber mesh cloth 4022 all have good tensile properties, so under the action of the reinforcement layer 402, the crack resistance of the anti-cracking waterproof layer 4 is guaranteed. Since the alkali-resistant glass fiber mesh cloth 4022 itself also has good acid and alkali corrosion resistance, the anti-cracking waterproof layer 4 also has certain acid and alkali corrosion resistance.

[0035] like Figure 1-Figure 2 As shown, in this embodiment, the first steel mesh layer 4021 and the second steel mesh layer 4023 are both woven with steel wires, and the first steel mesh layer 4021 and the second steel mesh layer 4023 are both in contact with the alkali-resistant glass fiber mesh cloth 4022 .

[0036] As an implementation method, the specific steel mesh layer and the second steel mesh layer 4023 are both woven with stainless steel wire, which can effectively ensure the strength and corrosion resistance of the steel mesh layer 1 4021 and the second steel mesh layer 4023. At the same time, the alkali-resistant glass fiber mesh cloth 4022 is arranged between the steel mesh layer 1 4021 and the second steel mesh layer 4023, which can ensure that the alkali-resistant glass fiber mesh cloth 4022 is reliably pressed and installed between the steel mesh layer 1 4021 and the second steel mesh layer 4023.

[0037] like Figure 1-Figure 2 As shown, in this embodiment, the first steel mesh layer 4021 is bonded to the first anti-cracking mortar layer 401 , and the second steel mesh layer 4023 is bonded to the second anti-cracking mortar layer 403 .

[0038] As an embodiment, when the steel mesh layer 1 4021 and the steel mesh layer 2 4023 are reliably installed and laid on the outside of the building exterior wall, the tensile strength of the crack-resistant waterproof layer 4 can be improved by means of the structure of the steel mesh layer 1 4021 and the steel mesh layer 2 4023 themselves.

[0039] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the waterproof roll 404 is a waterproof roll made of polyethylene polypropylene, and a connecting component 6 is arranged on the waterproof roll 404.

[0040] As an embodiment, the waterproof roll material of polyethylene polypropylene has excellent crack resistance and waterproof properties. Even when the anti-cracking mortar layer 1 401 and the anti-cracking mortar layer 2 403 are thermally blocked and shrunk due to the external ambient temperature, the waterproof roll material 404 is tightly fitted to the exterior wall of the building. Therefore, the waterproof roll material 404 can effectively prevent external water vapor from invading the exterior wall of the building.

[0041] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the connecting assembly 6 includes a limiting bolt 601 installed on the insulation board 3 and a fixing nut 602 installed on the end of the limiting bolt 601 facing away from the insulation board 3.

[0042] As an embodiment, the connecting component 6 is mainly used to achieve reliable limited installation of the waterproof membrane 404 during laying. Before installing the insulation board 3, the limit bolt 601 needs to be passed through the insulation board 3, and then the insulation board 3 is laid and installed. Subsequently, when laying the anti-cracking waterproof layer 4, each part of the anti-cracking waterproof layer 4 passes through the limit bolt 601 at a time until the end of the limit bolt 601 extends out of the waterproof membrane 404. Then, the fixing nut 602 is tightened to achieve the compression and limitation of the waterproof membrane 404.

[0043] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the limiting bolt 601 passes through the insulation board 3 and the anti-cracking waterproof layer 4, and the fixing nut 602 is located on the outside of the waterproof coiled material 404.

[0044] As an embodiment, when the fixing nut 602 is tightened, the waterproof membrane 404 can be reliably pressed against the outside of the second anti-cracking mortar layer 403 under the compression action of the fixing nut 602, thereby achieving reliable positioning of the waterproof membrane 404 after laying.

[0045] like Figure 1 、 Figure 3 and Figure 5 As shown, in this embodiment, a countersunk hole 7 is further provided on the insulation board 3 at the position of the limiting bolt 601 . The countersunk hole 7 passes through the insulation board 3 , and the size of the countersunk hole 7 matches the size of the limiting bolt 601 .

[0046] As an embodiment, the countersunk hole 7 can ensure that the limiting bolt 601 can pass through easily, so as to ensure that the contact surface between the insulation board 3 and the mortar leveling layer 2 is smooth during installation.

[0047] The specific implementation process of this embodiment is as follows: when in use, first lay a mortar leveling layer 2 on the outside of the base wall 1, and then install the insulation board 3 with the connecting assembly 6 on the mortar leveling layer 2 through the plastering mortar, and then just install the anti-cracking waterproof layer 4 and the finishing layer 5 on the outside of the insulation board 3 in sequence, so that the building exterior wall can be put into use. During use, by installing the anti-cracking waterproof layer 4 composed of the anti-cracking mortar layer 1 401, the anti-cracking mortar layer 2 403, the reinforcement layer 402 and the waterproof membrane 404 on the outside of the insulation board 3 on the building exterior wall, the building exterior wall can not only effectively increase the crack resistance and acid and alkali corrosion resistance of the anti-cracking waterproof layer 4 under the action of the reinforcement layer 402, the anti-cracking mortar layer 1 401 and the anti-cracking mortar layer 2 403 when in use, but also can effectively block external water vapor from invading the base wall 1 under the action of the waterproof membrane 404, avoiding leakage, so that the building exterior wall has better anti-cracking and anti-leakage performance when in use, and is safer and more reliable to use.

[0048] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
