The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0037] like Figures 1 to 5 As shown in the figure, this application provides a concrete anti-seepage construction structure for a bathroom, including: a base plate 1, an anti-seepage barrier 2, and a first water-blocking strip 4. The anti-seepage barrier 2 is disposed on the base plate 1, and the anti-seepage barrier 2 encloses an inner cavity 21 and an opening 22 communicating with the inner cavity 21. A joint surface 3 is formed between the anti-seepage barrier 2 and the base plate 1. The first water-blocking strip 4 extends along the anti-seepage barrier 2 and is disposed through the joint surface 3. One side of the first water-blocking strip 4 along the width direction is located inside the base plate 1, and the other side of the first water-blocking strip 4 along the width direction is located inside the anti-seepage barrier 2. Both ends of the first water-blocking strip 4 along the length direction extend to both sides of the opening 22. The distance between the end of the first water-blocking strip 4 and the thickness end face of the anti-seepage barrier 2 located on the side of the opening 22 is 1cm to 10cm, so that the first water-blocking strip 4 is as close as possible to the opening 22, thereby extending the waterproofing distance. The width of the first water-blocking strip 4 is 4cm to 6cm, and the first water-blocking strip 4 extends 2cm to 3cm beyond the bottom plate 1 along the width direction, thus having a good water-blocking effect.

[0038] This application addresses the problem of water leakage at the joint between the bottom of the concrete curb 2 in the bathroom and the base slab 1 of the main structure. A water-blocking strip is added to the joint surface between the bottom of the curb 2 and the main structure. The first water-blocking strip 4 is installed in the middle of the bathroom wall before the base slab concrete is poured. This can effectively prevent water leakage at the bottom joint of the concrete curb 2 after it is poured. At the same time, the quality of the bottom joint concrete can be controlled according to the height of the first water-blocking strip 4.

[0039] In some possible implementations, the first water-blocking strip 4 is located at the middle of the anti-reflective curb 2 along its thickness direction. Experiments have shown that the water-blocking effect is better when the water-blocking strip is located at the middle of the anti-reflective curb 2.

[0040] In some possible implementations, the first water-stop strip 4 is a metal steel plate with a thickness of 3mm to 4mm. The first water-stop strip 4 serves as a water-stop steel plate. Studies of similar basement waterproof guide wall water-stop steel plates have shown that seepage and leakage are significantly reduced, and the technical system for water-stop steel plates is already quite mature. Therefore, installing a water-stop steel strip at the bottom joint of the bathroom curb 2 can greatly reduce seepage and leakage during water spray tests, reducing subsequent repair costs.

[0041] In some possible implementations, the base plate 1 has a steel reinforcement assembly, to which the first water-retaining strip 4 is fixed. The first water-retaining strip 4 can be fixed to the steel reinforcement assembly by cable ties or wire. Preferably, the first water-retaining strip 4 can be welded to the steel reinforcement assembly. Along the length of the first water-retaining strip 4, a portion (lower edge) of the first water-retaining strip 4 is welded to the steel reinforcement assembly to improve the structural stability of the first water-retaining strip 4 and to prevent it from tipping over or being severely bent and deformed during the pouring of the concrete for the inverted curb 2.

[0042] In some possible implementations, the reinforcing bar assembly (not shown) includes longitudinal bars and stirrups fitted onto the longitudinal bars, forming a reinforcing cage. The arrangement of the longitudinal bars and stirrups is conventional in the art, and its structure will not be described in detail here. The first water-blocking strip 4 is arranged parallel to the longitudinal bars, and its lower edge is supported on the stirrups. The first water-blocking strip 4 is welded to a portion of the stirrups. The first water-blocking strip 4 and the stirrups can be fixed by spot welding.

[0043] In some possible implementations, such as Figure 2 As shown, the first water-blocking strip 4 includes multiple first straight sections 41 and multiple bent sections 42. The bent sections 42 are integral pieces. Each bent section 42 includes two perpendicular second straight sections 421. The two second straight sections 421 are smoothly transitioned by an arc-shaped plate section. The second straight sections 421 and the corresponding first straight sections 41 are sealed together.

[0044] The first water-retaining strip 4 is relatively large and requires multiple structural segments to be spliced ​​together. The first water-retaining strip 4 has only two structural segments: a straight segment 41 and a bent segment 42. At least one straight segment 41 can be placed between two bent segments 42, and adjacent straight segments 41 or adjacent bent segments 42 and straight segments are sealed together. The bent segment 42 is a single piece, formed by directly bending a steel strip, resulting in good structural strength.

[0045] In some possible implementations, the thickness end faces of the first straight section 41 and the second straight section 421 are fitted together, and both sides of the first straight section 41 and the second straight section 421 are fully welded at the splice seam 3 along the thickness direction. Each structural plate segment should be test-welded before welding to adjust the current parameters. Excessive current can easily burn or even burn through the steel plate, while insufficient current makes arc initiation difficult and the weld weak. Adjacent structural plate segments should be fully welded on both sides at the overlap. During welding, a fireproof blanket should be laid underneath and moistened with water to prevent ignition of the wooden formwork and potential fire.

[0046] In some possible implementations, the waterproofing structure of the bathroom concrete curb 2 includes a compensating plate 43. The compensating plate 43 covers the first straight section 41 and the second straight section 421 that are joined together, and covers the gap between the first straight section 41 and the second straight section 421. The periphery of the compensating plate 43 is fully welded to the first straight section 41 and the second straight section 421. The compensating plate 43 can also be a steel plate. One periphery of the compensating plate 43 is fully welded to two adjacent sections of the first water-retaining strip 4, which further improves the sealing performance and enhances the structural strength of the first water-retaining strip 4.

[0047] In some possible implementations, such as Figure 4 As shown, bent edges 4a can be provided on the upper and lower edges of the first water-blocking strip 4, that is, on both sides of the width direction. The bent edges 4a bend towards the inner cavity 21, thereby preventing water from seeping upward or downward.

[0048] In some possible implementations, the waterproofing structure of the bathroom concrete curb includes a second water-retaining strip 5. The second water-retaining strip 5 is located on the side of the first water-retaining strip 4 near the inner cavity 21. The second water-retaining strip 5 penetrates the joint surface 3. One side of the second water-retaining strip 5 is located inside the base plate 1, and the other side is located inside the curb 2. Both ends of the second water-retaining strip 5 extend to both sides of the opening 22. The second water-retaining strip 5 is located inside the first water-retaining strip 4 and is approximately parallel to it. The first water-retaining strip 4 forms the first waterproofing layer, and the second water-retaining strip 5 forms the second waterproofing layer. This double-layer waterproofing structure significantly improves the waterproofing effect.

[0049] like Figure 5As shown, the second water-blocking strip 5 includes a horizontal strip 51 and a vertical strip 52. The horizontal strip 51 is located inside the base plate 1 to prevent water from seeping downwards. The vertical strip 52 is vertically connected to the horizontal strip 51, extends out of the base plate 1, and extends into the anti-reflective curb 2 to block water from seeping along the thickness direction of the anti-reflective curb. The vertical strip 52 is located on the side of the water platform away from the inner cavity 21. The second water-blocking strip 5 can also be a steel plate, or it can be multiple steel plate segments spliced ​​and welded together. The second water-blocking strip 5 is also welded to the reinforcing steel reinforcement, and the stirrups welded to the second water-blocking strip 5 can be staggered from the stirrups welded to the first water-blocking strip 4.

These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
