[0031] The following is combined with Figure 1-5 This application is described in further detail.
[0032] The embodiment of the present application discloses an anti-leakage structure for exterior wall windowsills. Figure 1 The outer wall 1 is made of bricks, and the outer wall 1 is provided with an opening 13 for accommodating the window 2; the anti-leakage structure is arranged at the bottom of the opening 13, and the anti-leakage structure is fixedly connected to the outer wall 1 by mortar.
[0033] Reference Figure 1 The exterior wall window sill anti-leakage structure includes a concrete body 10, which includes a capping strip 3 and a protective block 4. There are two protective blocks 4, which are arranged on both sides of the capping strip 3 along the length of the exterior wall 1. The capping strip 3 and the protective blocks 4 are integrally cast from concrete. The concrete body 10 can be made in a factory or on a construction site, and then transported to the window sill of the exterior wall 1 for installation.
[0034] Reference Figure 2 Along the direction from the inner side 11 to the outer side 12 of the outer wall 1, the elevation of the top strip 3 decreases, the elevation of the protective block 4 is greater than the elevation of the top strip 3, and a concave angle area 5 is formed between the protective block 4 and the top strip 3. The window 2 is fixed between the two protective blocks 4, and the window 2 is fixedly connected to the protective block 4 and the top strip 3.
[0035] Reference Figure 1 and Figure 2 The implementation principle of the exterior wall window sill anti-leakage structure in the embodiment of the present application is as follows:
[0036] Reference Figure 1 and Figure 2 The capping strip 3 of the window sill is designed to be higher inside and lower outside, allowing rainwater to drain promptly from the window sill, reducing the penetration of rainwater into the exterior wall 1 and improving the anti-leakage performance of the window sill area of the exterior wall 1. At the same time, the capping strip 3 and the protective block 4 are integrally formed, thereby reducing the occurrence of cracks in the inner corner area 5 of the window sill of the exterior wall 1 and improving the anti-leakage performance of the inner corner area 5 of the window sill of the exterior wall 1, thereby further improving the anti-leakage performance of the window sill of the exterior wall 1.
[0037] Example 2
[0038] The difference between this embodiment 2 and embodiment 1 is that:
[0039] Reference Figure 3 The anti-leakage structure also includes a waterproof coating layer 6, which is applied to the outer periphery of the concrete body 10. Along the width direction of the exterior wall 1, the inner corner area 5 of the concrete body 10 is provided with an arc-shaped groove 14, which is filled with the waterproof coating layer 6. By brushing the waterproof coating layer 6 on the outer periphery of the concrete body 10, the waterproof performance of the concrete is improved, and the leakage of water on the window sill toward the exterior wall 1 is reduced. At the same time, the arc-shaped groove 14 is provided in the inner corner area 5 of the concrete body 10 to locally increase the thickness of the waterproof coating layer 6; thereby reducing the stress concentration effect of the waterproof coating layer 6 in the inner corner area 5, reducing the cracking of the waterproof coating at the inner corner, and further improving the anti-leakage performance of the window sill of the exterior wall 1.
[0040] Reference Figure 3In this embodiment, the concrete used to cast the protective blocks 4 and capping strips 3 is mixed with tensile-resistant fibers 7. The tensile-resistant fibers 7 can be polypropylene fibers or other synthetic fibers. In this embodiment, the tensile-resistant fibers 7 are polypropylene fibers. Adding polypropylene fibers or other synthetic fibers to concrete can improve the toughness and crack resistance of the concrete, reduce cracks caused by shrinkage and temperature changes, and further enhance the anti-permeability performance of the concrete body 10.
[0041] Example 3
[0042] The difference between this embodiment 3 and embodiment 2 is that:
[0043] Reference Figure 4 The anti-leakage structure also includes a waterstop steel plate 8 and connecting steel bars 9. The waterstop steel plate 8 is embedded in the inner corner area 5 of the concrete body 10. In this embodiment, the waterstop steel plate 8 is formed by bending a sheet of steel and includes a straight section 82 and a chamfered section 83. The straight section 82 has two sections, which are arranged perpendicular to each other. The straight section 82 is disposed in the inner corner area 5 of the concrete body 10, and the chamfered sections 83 are fixed on both sides of the straight section 82 and embedded in the concrete body 10. In this embodiment, the waterstop steel plate 8 is embedded in the middle of the concrete body 10; in other embodiments, the waterstop steel plate 8 can also be embedded on the outer peripheral surface of the concrete body 10. By providing the waterstop steel plate 8 in the inner corner area 5 of the concrete body 10, water on the window sill can be prevented from penetrating into the bricks of the exterior wall 1, thereby further improving the anti-leakage performance of the window sill of the exterior wall 1. The end of the waterstop steel plate 8 is provided with a chamfered portion to further improve the connection strength between the waterstop steel plate 8 and the concrete body 10, so as to give full play to the waterstop performance of the waterstop steel plate 8.
[0044] Reference Figure 4 One end of the connecting steel bar 9 is welded to the waterstop steel plate 8 and the connecting steel bar 9 is embedded in the concrete body 10. The connecting steel bar 9 connects the waterstop steel plate 8 and the concrete body 10 to improve the connection strength between the waterstop steel plate 8 and the concrete body 10, give full play to the synergistic effect of the waterstop steel plate 8 and the concrete body 10, and further improve the anti-leakage performance of the window sill of the exterior wall 1.
[0045] Example 4
[0046] The difference between this embodiment 4 and embodiment 3 is that:
[0047] Reference Figure 5 In this embodiment, the waterstop steel plate 8 can also be buried on the outer peripheral surface of the concrete body 10; that is, when pouring the concrete body 10, the waterstop steel plate 8 acts as a part of the formwork to facilitate the workers to pour the concrete body 10.
[0048] Reference Figure 5Specifically, waterstop steel plate 8 also includes an arcuate segment 81, which is fixedly disposed between two straight segments 82. Arcuate segment 81 is affixed to the sidewalls of arcuate groove 14, while straight segments 82 are affixed to the periphery of protective block 4 and capping strip 3. Waterstop steel plate 8 is affixed to the periphery of concrete body 10 to provide a good water-stopping effect, further improving the anti-leakage performance of the window sill of exterior wall 1.
[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
