[0001] The present application relates to the technical field of building waterproofing, and in particular to a waterproofing component for gaps in the exterior walls of assembled buildings. Background Art
[0002] When existing prefabricated buildings are overlapped and installed during construction, gaps will form between the upper and lower layers of exterior wall panels. Currently, waterproofing the gaps in the exterior wall panels of prefabricated buildings at home and abroad is a major difficulty. Because there are many gaps, waterproofing is basically done with materials such as sealants, rubber strips, high and low tongues and grooves, and expansion strips.
[0003] The gap waterproofing measures and waterproofing materials currently used are basically flexible materials. If there is movement between the wall panels after the materials solidify, these materials will crack, causing local waterproofing failure and further causing water seepage in the exterior wall. In addition, these materials have poor weather resistance, cannot be replaced at any time, and are not flexible enough. Utility Model Content

[0036] The embodiment of the present application provides a waterproof component for the gap of the outer wall of an assembled building, such as Figure 1-Figure 4 As shown, the waterproof assembly includes two embedded plates 100 and a self-adhesive sealing strip 200. The two embedded plates 100 are used to be embedded in the exterior wall board 1 at the upper and lower sides of the opening of the exterior wall gap 10, respectively. The embedded plates 100 have an inner plate body 110 located on the inner wall of the exterior wall gap 10 and an outer plate body 120 located on the outer wall of the exterior wall board 1. The self-adhesive sealing strip 200 includes a body 210, a first waterproof self-adhesive adhesive 220 and a second waterproof self-adhesive adhesive 230. The cross section of the body 210 is T-shaped. The body 210 includes a cover plate 211 and an insertion strip 212 vertically connected to one side of the cover plate 211. The first waterproof self-adhesive adhesive 220 is arranged on the side of the cover plate 211 facing the insertion strip 212. The second waterproof self-adhesive adhesive 230 covers the outer surface of the insertion strip 212. The insertion strip 212 is used to be inserted into the outer wall gap 10 and is bonded to the two inner plate bodies 110 through the second waterproof self-adhesive adhesive 230; the cover plate 211 is used to cover the outer wall gap 10 and is bonded to the two outer plate bodies 120 through the first waterproof self-adhesive adhesive 220.
[0037] In the embodiment of the present application, the waterproof component forms a smooth interface at the opening of the external wall gap 10 through the embedded plate 100. When installing the self-adhesive sealing strip 200, the insert strip 212 of the main body 210 is inserted into the external wall gap 10 and the cover plate 211 is pressed, so that the insert strip 212 is tightly bonded to the upper and lower inner plates 110 in the external wall gap 10 through the second waterproof self-adhesive 230, so that the cover plate 211 covers the opening of the external wall gap 10, and is tightly bonded to the outer plate body 120 of the outer wall of the external wall board 1 on both sides of the opening through the first waterproof self-adhesive 220, similar to a "bottle stopper" to achieve a sealing and waterproofing effect. After the installation is completed, a rigid and flexible waterproof measure will be formed, which can withstand certain activities and displacements of the building, form multiple waterproof barriers, and solve the possibility of rainwater entering the gap at one time. At the same time, the installation is simple and quick, the waterproof effect is good, and it can be replaced at any time as needed.
[0038] The body 210 of the self-adhesive sealing strip 200 can be made of silicone material, rubber material or aluminum alloy. Preferably, a rubber material with a certain deformation ability is used. The cover plate 211 and the insert strip 212 of the body 210 are an integrated structure and can be formed by extrusion injection molding.
[0039] In one embodiment, if Figure 1-Figure 2 and Figure 4 As shown, the outer surface of the insert 212 is uniformly provided with grooves.
[0040] By providing a groove on the outer surface of the insert 212 , the area and roughness of the outer surface of the insert 212 are increased, thereby improving the bonding strength between the second waterproof self-adhesive 230 and the insert 212 and preventing the second waterproof self-adhesive 230 from falling off the insert 212 .
[0041] In one embodiment, if Figure 1-Figure 3 As shown, one end of the inner panel 110 is connected to one end of the outer panel 120, and the inner panel 110 is perpendicular to the outer panel 120. One end of the inner panel 110 away from the outer panel 120 and one end of the outer panel 120 away from the inner panel 110 are respectively vertically connected with an embedded body 130, and the embedded body 130 is used to be embedded in the exterior wall panel 1.
[0042] Specifically, in one implementation, the cover plate 211 of the body 210 is 60 mm wide, the insertion strip 212 of the body 210 is about 50 mm in the insertion direction, the inner plate 110 of the embedded body 130 is 40 mm wide, the outer plate 120 is 20 mm wide, and the embedded body 130 is 15 mm wide.
[0043] In a specific embodiment, the inner plate body 110 , the outer plate body 120 and the embedded body 130 are an integrated structure, which is convenient for processing and manufacturing, and increases the connection strength between the inner plate body 110 , the outer plate body 120 and the embedded body 130 .
[0044] Specifically, the embedded plate 100 can be formed by stamping and bending a stainless steel plate with a thickness of 1 mm.
[0045] In one embodiment, if Figure 1-Figure 2 and Figure 4 As shown, the waterproof assembly further includes a decorative plate 300 , which is disposed on a side of the cover plate 211 away from the insert strip 212 .
[0046] The decorative plate 300 can cover the cover plate 211 and play a decorative role.
[0047] In a specific embodiment, the color of the decorative panel 300 is the same as the color of the exterior wall panel 1 .
[0048] In some embodiments, Figure 1 and Figure 2 As shown, the waterproof component also includes a water-swellable waterstop strip 400, which is used to be arranged in the outer wall gap 10.
[0049] The water-swellable waterstop strip 400 cooperates with the self-adhesive sealing strip 200 to form a multi-layer waterproof barrier, which can solve the possibility of rainwater entering the gap at one time and eliminate the possibility of water seepage in the gap.
[0050] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0051] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
