Description

Technical Field

[0001] The utility model relates to the field of exterior wall waterproofing, in particular to an exterior wall joint waterproofing structure. Background Art

[0002] In modern buildings, the waterproof performance of exterior walls is one of the key factors to ensure building durability and living comfort. Most existing building exterior walls are assembled and connected to the outside of the building using prefabricated exterior wall structures. When assembling such prefabricated exterior wall structures, in order to prevent the prefabricated wall panels from deforming as the structural components deform, the separation seams between each prefabricated panel should not be less than 10mm. The standard separation seam is 20mm, which means that the on-site assembly of prefabricated buildings will leave a large number of assembly seams, which can easily become channels for water penetration.

[0003] After the existing building exterior walls are assembled, they usually need to be filled with waterproof materials and sealed with structural adhesive at the assembly joints to improve the waterproof performance of the building exterior walls. Although this waterproofing operation method can meet conventional waterproofing needs, it is prone to aging after long-term use, resulting in a decrease in the bonding effect of the glue, thereby significantly reducing the waterproof effect of the overall waterproof material.

It is characterized in that a waterproof assembly is fixedly installed in the joint between the insulation board body 2 and the waterproof board assembly.

[0027] The embodiment of the present application provides an exterior wall joint waterproof structure that combines multiple layers of waterproof structures with each other and cooperates with waterproof strips with water-guiding effects to fill gaps to ensure the stability of the overall waterproof effect. This solves the problem in the prior art that conventional filling waterproof materials and sealing structural adhesives are prone to aging after long-term use, resulting in reduced bonding effect of the adhesive, thereby significantly reducing the waterproof effect of the overall waterproof material. The overall idea of this embodiment to solve the above problem is: by setting a waterproof structure consisting of a closed waterproof rubber strip 5, a rubber waterstop 6, a filling protective plate 7, a joint glue 8, an upper waterproof strip 901, a lower waterproof strip 902 and a water-guiding slope 903, the exterior wall of the building can be made into a composite waterproof component using a multi-layer waterproof structure, and cooperate with the joint glue 8 to ensure the overall waterproof effect of the exterior wall of the building. After long-term use, when other parts age and there is water seepage, the built-in upper waterproof strip 901, the lower waterproof strip 902 and the water-guiding slope 903 can guide and discharge the infiltrated water to ensure the waterproof effect of the overall waterproof material.

[0028] like Figure 1 and Figure 2 As shown, the waterproof assembly consists of a closed waterproof rubber strip 5, a rubber waterstop 6 and a filling protective plate 7;

[0029] As an embodiment, the waterproof assembly consisting of a closed waterproof rubber strip 5, a rubber waterstop 6 and a filling protective plate 7 has multiple waterproof effects. At the same time, the filling protective plate 7 can provide a protective effect for the rubber waterstop 6, preventing the rubber waterstop 6 from being worn, thereby ensuring the waterproof effect of the rubber waterstop 6.

[0030] like Figure 1 and Figure 2 As shown, the closed waterproof rubber strip 5 is fixedly installed at the joint between the insulation boards 2;

[0031] As an embodiment, the closed waterproof rubber strip 5 can fill the gaps at the joints between the insulation panels 2 to ensure the sealing effect and provide a layer of sealing and waterproof effect.

[0032] like Figure 1 and Figure 2 As shown, the rubber water stop 6 and the filling protection plate 7 are fixedly installed at the joints between the waterproof board components;

[0033] As an embodiment, the rubber waterstop 6 can provide basic waterproofing effect for the waterproof board assembly, ensuring the overall waterproofing effect of the waterproof board assembly. At the same time, the filling protective plate 7 can provide protective support effect for the rubber waterstop 6, preventing the rubber waterstop 6 from being bumped by the outside, ensuring that the structural shape of the rubber waterstop 6 remains stable, and at the same time ensuring the water-stopping effect of the rubber waterstop 6.

[0034] like Figure 1-Figure 3 As shown, the waterproof board assembly is composed of an inner waterproof board 3 and an outer waterproof board 4;

[0035] As an embodiment, the inner page waterproof board 3 provides bonding connection and internal waterproofing effect for the waterproof board assembly, and the outer page waterproof board 4 provides exterior decoration and external waterproofing effect for the waterproof board assembly, so that the waterproof board assembly can have multiple waterproofing effects, stable bonding effect and appearance decoration effect.

[0036] like Figure 1 and Figure 2 As shown, the upper and lower ends of the rubber water stop 6 are formed with an embedding seat 601, the joints between the inner page waterproof plates 3 are provided with an embedding groove 602 that matches the embedding seat 601, the upper and lower ends of the filling protective plate 7 are formed with a fixing seat 701, and the joints between the outer page waterproof plates 4 are provided with a fixing groove 702 that matches the fixing seat 701;

[0037] As an embodiment, the rubber waterstop 6 with the embedding seat 601 can establish a stable connection relationship with the inner page waterproof board 3 through the embedding groove 601 opened on the inner page waterproof board 3, ensuring the structural connection and usage state of the rubber waterstop 6, thereby ensuring the stability of the waterproof effect of the rubber waterstop 6.

[0039] As an embodiment, the upper waterproof strip 901 and the lower waterproof strip 902 can provide the rubber waterstop 6 and the filling protective plate 7 with anti-seepage effects at the upper and lower ends. When other components such as the waterproof board assembly are aged, water can easily penetrate into the interior of the waterproof board assembly through the gaps between the structures and seep downward, while the upper waterproof strip 901 can guide the seeped water and discharge it to both ends under the action of its water guide slope 903. When the joint glue 8 is aged, water can easily penetrate into the filling protective plate 7 or the rubber waterstop 6 through the gaps at the upper and lower ends of the joint glue 8. Under the water-blocking effect of the rubber waterstop 6, the water will seep downward, while the lower waterproof strip 902 can guide the seeped water and discharge it to both ends under the action of its water guide slope 903. In summary, the upper waterproof strip 901 and the lower waterproof strip 902 can effectively prevent water from continuing to seep in, thereby improving the overall waterproof effect of the waterproof assembly and the waterproof board assembly.

[0040] like Figure 2-Figure 4As shown, the waterproof assembly further includes a joint glue 8 bonded to the joint between the insulation board body 2 and the waterproof board assembly;

[0041] As an embodiment, the joint glue 8 can fill the splicing gaps reserved when the prefabricated insulation board body 2 and the waterproof board assembly are spliced, and can seal the closed waterproof rubber strip 5, rubber water stop 6, filling protective plate 7, upper waterproof strip 901 and lower waterproof strip 902 at the joints to prevent them from contacting with the outside air, thereby reducing their aging degree and increasing their service life, while also providing a layer of waterproof effect.
