DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0041] Please refer to Figures 1-6In this embodiment of the utility model, a combined building waterproofing board for building engineering includes a waterproofing board body 1, an upper and lower snap-fit ​​structure 2 and a two-sided butt joint structure 3. The waterproofing board body 1 includes a concrete shell 104; the upper and lower snap-fit ​​structure 2 is fixedly installed on the upper and lower surfaces of the concrete shell 104; the two-sided butt joint structure 3 is fixedly installed on the two-sided surfaces of the concrete shell 104.

[0042] Specifically, depending on the size of the building wall area to be covered, select an appropriate number of waterproof board main bodies 1. Several waterproof board main bodies 1 are connected to each other on both sides through the two-sided connecting structure 3 and attached to the surface of the building wall to form a first-level waterproof exterior wall. The upper and lower interlocking structure 2 connects each waterproof board main body 1 vertically and attaches it to the surface of the building wall. They are stacked and spliced ​​step by step and attached to the surface of the building wall to form a relatively integrated waterproof exterior wall. This process shares the burden of the adhesive layer with the wall during the application, preventing individual waterproof board main bodies 1 from detaching from the wall and falling off when the adhesive layer fails, thus reducing the accident rate. At the same time, the upper and lower interlocking structure 2 and the two-sided connecting structure 3 are all sealed and waterproofed, eliminating the need for subsequent waterproof filling and sealing work between the various waterproof board main bodies 1.

[0043] Example 1

[0044] like Figure 5 As shown, in this embodiment, the upper and lower snap-fit ​​structure 2 includes a first sealing strip 201, a snap-fit ​​strip covering groove 202, a snap-fit ​​strip 203, and a first abutting side strip 204. The first sealing strip 201 is fixedly installed on the upper surface of the concrete shell 104; the snap-fit ​​strip covering groove 202 is opened in the middle of the first sealing strip 201; the snap-fit ​​strip 203 is fixedly installed in the middle of the bottom side of the concrete shell 104; and the first abutting side strip 204 is fixedly installed on the front and rear edges of the bottom of the concrete shell 104.

[0045] In this embodiment, when the waterproof membrane bodies 1 are joined together vertically, the elasticity of the No. 1 sealing strip 201 is used to insert the trapezoidal cross-section snap-fit ​​strip 203 into the snap-fit ​​strip covering groove 202. While pressing down, the inclined surface of the bottom side of the No. 1 abutting side strip 204 is used to press against and squeeze both sides of the No. 1 sealing strip 201, so that the No. 1 sealing strip 201 can tightly cover the snap-fit ​​strip 203, achieving a tight snap-fit ​​while providing a sealing effect.

[0046] like Figure 6As shown, in this embodiment, the two-sided mating structure 3 further includes a second sealing strip 301, an insertion groove 302, a limiting side strip 303, an insertion strip 304, and a second abutment side strip 305. The second sealing strip 301 is fixedly installed on one side surface of the concrete shell 104; the insertion groove 302 is opened in the middle of the second sealing strip 301; the limiting side strip 303 is fixedly installed on the front and rear edges of the second sealing strip 301; the insertion strip 304 is fixedly installed on the other side surface of the concrete shell 104; and the second abutment side strip 305 is fixedly installed on the front and rear edges of the other side surface of the concrete shell 104.

[0047] In practice, when the two sides of each waterproof membrane body 1 are joined together, the insertion strip 304 is inserted into the insertion groove 302 from the top and bottom. At the same time, during the insertion process, the second abutment side strip 305 is used to abut against the front and rear sides of the second sealing strip 301 to strengthen the insertion effect between the insertion groove 302 and the insertion strip 304, and at the same time provide a strengthening effect.

[0048] Example 2

[0049] Based on Embodiment 1, this invention supplements the specific method by which the waterproof membrane body 1 itself performs waterproofing work, which was not mentioned in Embodiment 1.

The mesh skeleton 101 is embedded inside the concrete shell 104; the adhesive layer 102 fills each mesh hole of the mesh skeleton 101; the waterproof fabric layer 103 is attached to the front and rear surfaces of the adhesive layer 102; there are several protrusions 105, which are arranged in a rectangular array and fixedly installed on the rear surface of the concrete shell 104; the grooves 106 are formed on the outer surface of the protrusions 105.

[0051] In the embodiment, the grid skeleton 101 is used as the internal skeleton of the concrete shell 104 to strengthen the overall strength of the waterproof plate body 1, the adhesive layer 102 and the waterproof cloth layer 103 are used to provide waterproof effect, and the concrete shell 104 is prevented from being water seepage due to the gap. In production, a waterproof cloth layer 103 is first laid, then the grid skeleton 101 is placed, the adhesive layer 102 is filled in the mesh hole, then a waterproof cloth layer 103 is laid again, the adhesive layer 102 is used to support the front and rear waterproof cloth layers 103 and bond the two waterproof cloth layers 103, and finally the cement is directly poured to completely cover the grid skeleton 101, the adhesive layer 102 and the waterproof cloth layer 103 to form the waterproof plate body 1, so that the pure concrete plate is not too thin and fragile, and when attached to the wall surface, the convex block 105 and the concave and convex groove mark 106 formed on the surface of the convex block 105 are used to increase the roughness of the rear surface of the concrete shell 104, form a concave-convex structure, increase the entanglement effect with the attached adhesive layer, and increase the attachment firmness.
