[0002] In the construction of high-rise buildings, in order to eliminate or reduce the adverse effects of shrinkage deformation and settlement deformation of concrete due to temperature changes on the building, concrete post-casting strips are often set in certain parts of the basement. For example, the patent with publication number CN208379644U discloses a post-casting strip for basement construction, including a post-casting strip body and walls arranged on both sides of the post-casting strip, a bottom plate is arranged below the post-casting strip body, and a water-swelling waterstop strip is arranged on the side of the wall close to the post-casting strip body. The water-swelling waterstop strip is connected to the wall through waterproof glue, and the water-swelling waterstop strip is provided with a number of protrusions away from the wall. When new concrete is poured in the post-casting strip body, when water is about to flow into the gap, the water-swelling waterstop strip will expand to fill the gap between the concrete and the wall, but the waterproof glue and the wall will be unstable, and there are high requirements for the strength and cleanliness of the wall surface. After the waterproof glue ages, it will directly affect the anti-leakage effect.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a bottom plate post-casting belt construction joint anti-seepage structure, including a post-casting belt casting groove 2 between two wall bodies 1, a post-casting belt body 10 is cast in the post-casting belt casting groove 2, a plurality of step grooves 4 are opened on the wall body 1, the step grooves 4 are connected with the post-casting belt casting groove 2, a drainage component is installed in the step groove 4, a plurality of reinforcement components are installed in the post-casting belt casting groove 2, a water absorption component is installed on the reinforcement component, the water absorption component corresponds to the drainage component, and a leakage-proof component is provided between the groove wall of the step groove 4 and the post-casting belt body 10.

[0022] In this embodiment, a bottom plate 3 is installed on the lower side of the post-casting strip casting groove 2, the lower side of the wall 1 is fixedly connected to the bottom plate 3, the drainage component is a drainage groove 8, and the drainage groove 8 is opened at the bottom of the step groove 4. The reinforcement component includes multiple steel meshes 5, the ends of the steel meshes 5 are located in the step groove 4, and the steel meshes 5 are located above the drainage groove 8.

[0023] Specifically, a skeleton can be formed by the steel mesh 5, so that the strength of the post-cast strip body 10 formed by casting is relatively high, and the step structure can prevent the post-cast strip body 10 from falling off from the wall 1.

[0024] The water absorption component includes an insert block 7, which is fixedly connected to the steel mesh 5 and corresponds to the drainage groove 8. A plurality of cotton threads 6 are fixed on the steel mesh 5, and the ends of the cotton threads 6 are fixedly connected to the insert block 7. A plurality of capillary pores are provided in the insert block 7, and the bottoms of the capillary pores are connected to the drainage groove 8.

[0025] Specifically, after pouring is completed, the steel mesh 5, cotton thread 6, etc. will remain in the post-cast strip body 10. At this time, if there is water leakage in the post-cast strip body 10, the water can be absorbed by the cotton thread 6 and the plug 7, and then the water can be gathered in the drainage trough 8, so that the water can be discharged, which can achieve a better waterproof effect.

[0026] The waterproof board 9 is made of a material that swells when exposed to water.

[0027] Specifically, when the gap leaks, the waterproof board 9 can absorb water and swell, thereby playing a waterproof role. When the waterproof board 9 is damaged, the water leaked in the gap can also enter the drainage groove 8, and then can be discharged from the drainage groove 8, thereby ensuring the leakage-proof effect.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
