Description
Technical Field
[0001] This application relates to the field of building waterproofing technology, and in particular to a waterproofing structure for building exterior walls. Background Technology
[0002] Building exterior walls refer to the building envelope, serving functions such as load-bearing, thermal insulation, sound insulation, and fireproofing. To ensure the strength and durability of building exterior walls, they should have the basic function of preventing rainwater and snowmelt from penetrating the wall, and should also possess properties such as freeze-thaw resistance, high and low temperature resistance, and wind load resistance. Currently, building exterior walls mostly adopt prefabricated structures. After assembly, waterproof adhesive is usually directly filled into the gaps in the exterior wall to achieve waterproofing. However, with the extension of service life, the waterproof adhesive is easily affected by the external environment and is prone to peeling off, resulting in poor waterproofing effect and troublesome maintenance.

[0022] like Figures 1 to 7As shown, this application provides a waterproof structure for an exterior wall of a building, including multiple fixing blocks 1 and multiple first waterproofing mechanisms 2. The multiple fixing blocks 1 are all installed on the inner wall and are arranged at intervals along a first direction and a second direction, respectively. A first waterproofing mechanism 2 is provided between any two adjacent fixing blocks 1 along the first or second direction. The first waterproofing mechanism 2 includes a fixing beam 21, a through hole 22, an inner annular boss 23, a first annular adhesive strip 24, and a pressing assembly 25. The fixing beam 21 connects two fixing blocks 1, the through hole 22 is formed in the fixing beam 21, the inner annular boss 23 is formed on the inner side of the fixing beam 21 and located at one end of the through hole 22 near the inner wall, the first annular adhesive strip 24 is disposed in the through hole 22, and the pressing assembly 25 is installed on the inner wall and configured to press the first annular adhesive strip 24 against the inner annular boss 23.
[0023] It should be noted that the first direction above and below refers to the bidirectional direction along its axis, specifically as follows: Figure 1 The X-axis is shown in the diagram. The second direction, above and below, refers to the bidirectional direction along its axis, specifically as shown in the diagram. Figure 1 The Y-axis is shown below. The third direction below refers to the bidirectional direction along its central axis, specifically as follows: Figure 1 The Z-axis is shown in the figure.
[0024] This application provides a waterproof structure for building exterior walls. When the exterior wall 4 experiences slight movement or the first annular adhesive strip 24 shrinks due to external environmental influences, the clamping component 25 ensures that the first annular adhesive strip 24 remains pressed against the surface of the inner annular protrusion 23. Compared to existing technologies using waterproof adhesive, this provides better waterproofing, significantly reduces maintenance frequency, and improves ease of use. The first annular adhesive strip 24 also seals the through-hole 22, preventing rainwater from seeping between the exterior wall 4 and the interior wall.
[0025] In one embodiment of this application, please refer to Figures 1 to 7 The fixed beam 21 includes a middle beam (not shown in the figure) and two sets of connecting beams (not shown in the figure), with the middle beam installed between the two sets of connecting beams. The middle beam includes two intermediate arms 211, and each set of connecting beams includes two connecting arms 212.
[0026] With this configuration, the fixed beam 21 consists of a middle beam and two sets of connecting beams, which makes installation easier and more convenient compared to a one-piece molded structure.
[0027] In one embodiment of this application, please refer to the following: Figures 1 to 7The intermediate arm 211 includes an intermediate plate 2111 and an inner intermediate protruding plate 2112, the inner intermediate protruding plate 2112 being connected to the end of the intermediate plate 2111 near the inner wall. The connecting arm 212 includes a connecting plate 2121 and an inner connecting protruding plate 2122, the inner connecting protruding plate 2122 being connected to the end of the connecting plate 2121 near the inner wall. The inner annular boss 23 is formed by two inner intermediate protruding plates 2112 and four inner connecting protruding plates 2122.
[0028] With this configuration, the two inner middle protrusions 2112 and the four inner connecting protrusions 2122 can form an inner annular protrusion 23 inside the through hole 22. The clamping assembly 25 holds the first annular rubber strip 24 against the inner annular protrusion 23, which can seal the gap between the clamping assembly 25 and the fixing beam 21, thereby preventing rainwater from seeping between the outer wall 4 and the inner wall.
[0029] In one embodiment of this application, see [reference] Figures 1 to 7 The intermediate arm 211 also includes an intermediate limiting plate 2113, which is connected to the end of the inner intermediate protrusion 2112 away from the intermediate plate 2111, and is bent toward the first annular rubber strip 24 relative to the inner intermediate protrusion 2112. The connecting arm 212 also includes a connecting limiting plate 2123, which is connected to the end of the inner connecting protrusion 2122 away from the connecting plate 2121, and is bent toward the first annular rubber strip 24 relative to the inner connecting protrusion 2122.
[0030] With this configuration, the first annular rubber strip 24 can be limited by the middle limiting plate 2113 and the connecting limiting plate 2123, so that the first annular rubber strip 24 can always abut against the surface of the inner annular boss 23. This helps to improve the structural stability between the first annular rubber strip 24 and the inner annular boss 23 and ensures the waterproof effect.
[0031] In one embodiment of this application, please refer to Figures 1 to 7 The clamping assembly 25 includes multiple clamping elements 251 and a clamping plate 252. The multiple clamping elements 251 are all installed on the inner wall, and the clamping plate 252 is installed on the multiple clamping elements 251 and moves towards the inner wall in a third direction under the drive of the multiple clamping elements 251.
[0032] With this configuration, the pressure plate 252, under the action of multiple clamping elements 251, can always move towards the inner wall in the third direction, thereby ensuring that the first annular adhesive strip 24 always abuts against the inner annular protrusion 23. The first annular adhesive strip 24 can seal the gap between the pressure plate 252 and the inner annular protrusion 23, effectively preventing rainwater penetration and providing a good sealing effect. Furthermore, with multiple clamping elements 251 compared to having only one, the movement of the pressure plate 252 in the third direction is more stable, and the clamping effect of the pressure plate 252 on the first annular adhesive strip 24 is better.
[0033] In one embodiment of this application, please refer to the following: Figures 1 to 7 The clamping component 251 includes a fixed base 2511, a limiting rod 2512, a limiting block 2513, and a first elastic structure 2514. The fixed base 2511 is installed on the inner wall. The limiting rod 2512 passes through the fixed base 2511 and is installed on the clamping plate 252. The limiting block 2513 is installed at the end of the limiting rod 2512 away from the clamping plate 252. The first elastic structure 2514 is sleeved on the limiting rod 2512 and abuts against the fixed base 2511 and the limiting block 2513.
[0034] With this configuration, under the action of the first elastic structure 2514, the limiting block 2513 and the limiting rod 2512 can drive the pressing plate 252 to move towards the inner wall along the third direction, thereby ensuring that the first annular rubber strip 24 always abuts against the inner annular protrusion 23. The limiting rod 2512 guides the movement of the pressing plate 252, helping to improve the stability of the pressing plate 252's movement in the third direction, allowing the pressing plate 252 to stably press the first annular rubber strip 24. The limiting block 2513 limits the first elastic structure 2514, preventing it from detaching from the limiting rod 2512, thus improving the structural stability between the first elastic structure 2514 and the limiting rod 2512. Furthermore, when the first annular rubber strip 24 is damaged, the worker can easily replace it by moving the pressing plate 252 away from the inner wall along the third direction.
[0035] In one embodiment of this application, see [reference] Figures 1 to 7 The first waterproofing mechanism 2 also includes an outer strip-shaped boss 26, which is formed on the outside of the fixed beam 21 and located at the end of the through hole 22 away from the inner annular boss 23. A second waterproofing mechanism 3 is provided between the multiple outer strip-shaped bosses 26 and the outer wall 4.
[0036] With this configuration, the gap between the outer wall 4 and the multiple first waterproof mechanisms 2 can be sealed by the second waterproof mechanism 3 and the multiple outer strip protrusions 26, thus preventing rainwater penetration.
[0037] In one embodiment of this application, please refer to Figures 1 to 7 The intermediate arm 211 also includes an outer intermediate protrusion 2114, which is connected to the end of the intermediate plate 2111 away from the inner intermediate protrusion 2112. The connecting arm 212 also includes an outer connecting protrusion 2124, which is connected to the end of the connecting plate 2121 away from the inner connecting protrusion 2122. The outer strip-shaped protrusion 26 is formed by combining the outer intermediate protrusion 2114 and two outer connecting protrusions 2124.
[0038] With this configuration, the outer middle protrusion 2114 and the two outer connecting protrusions 2124 can enclose and form the outer strip protrusion 26. Through the second waterproof mechanism 3, the gap between the outer strip protrusion 26 and the outer wall 4 can be sealed, thereby preventing rainwater from seeping between the outer wall 4 and the inner wall through the gap between the outer strip protrusion 26 and the outer wall 4.
[0039] In one embodiment of this application, please refer to the following: Figures 1 to 7 The second waterproofing mechanism 3 includes a second annular adhesive strip 31 and a second elastic structure 32. The second annular adhesive strip 31 is disposed between the outer wall 4 and a plurality of outer strip protrusions 26, and the second elastic structure 32 abuts against the second annular adhesive strip 31 and the plurality of outer strip protrusions 26.
[0040] With this configuration, when the exterior wall 4 moves slightly or the second annular adhesive strip 31 shrinks due to the influence of the external environment, the second elastic structure 32 ensures that the second annular adhesive strip 31 is always pressed against the surface of the multiple outer strip protrusions 26. Compared with the existing technology that uses waterproof adhesive, the waterproof effect is better and the number of maintenance times can be reduced.
[0041] Optionally, the second elastic structure 32 is configured as an annular spring.
[0042] like Figures 1 to 7 As shown, the construction method for a waterproof structure of a building exterior wall provided in this application includes at least the following steps: Step S1: Install multiple exterior wall components 4 along the first direction.
[0043] Step S2: Install multiple fixing blocks 1 and multiple first waterproofing mechanisms 2 along the first direction.
[0044] Specifically, during installation, multiple outer wall sections 4 in the first direction are first installed onto the keel of the inner wall, and fixing blocks 1 are installed between adjacent outer wall sections 4. After the fixing blocks 1 are installed, the second annular rubber strip 31 and the second elastic structure 32 are installed. After installation, the intermediate beam is welded to the two connecting beams. After welding, the first annular rubber strip 24 is installed, and the clamping assembly 25 is passed through the through hole 22, and the fixing seat 2511 is installed to the inner wall using external bolts. This process is repeated, and the other outer wall sections 4 in the first direction and the first waterproofing mechanism 2 are installed in the same way.
[0045] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
