Description

Technical Field

[0001] This utility model relates to the technical field of precast slabs with advanced closure of post-pouring strips, and more specifically, to a structure for advanced closure of vertical post-pouring strips in basements. Background Technology

[0002] In the field of building construction, the sealing process of vertical post-pouring strips in basements has always been a critical and complex step. In order to improve construction efficiency, the post-pouring strips are sealed in advance.

[0003] Currently, precast slabs are used to close post-cast strips. However, the commonly used precast slabs for pre-sealing post-cast strips have insufficient support strength and deformation resistance. For example, CN 222796521 U discloses a pre-sealing structure for vertical post-cast strips in basements, which includes a basement waterproofing layer, pre-cast concrete, concrete reinforcement, steel plate waterstop, post-cast strip area, precast concrete slab, transverse reinforcement, longitudinal reinforcement, and reinforcement anchor rings. The pre-cast concrete is placed on the basement waterproofing layer, and concrete reinforcement and steel plate waterstop are placed inside the pre-cast concrete. The steel plate waterstop is located in the post-cast strip area formed by the pre-cast concrete. The precast concrete slab is placed below the post-cast strip area, and the transverse reinforcement, longitudinal reinforcement, and reinforcement anchor rings are placed inside the precast concrete slab.

[0004] As can be seen from the above-mentioned publicly available scheme, the precast concrete slab is made only of concrete and transverse and longitudinal steel bars, and its thickness is limited, which may lead to insufficient support strength. As a result, the precast concrete slab is easily deformed or broken by compression. Furthermore, the precast concrete slab is hoisted by steel bar anchor rings and then connected to the formwork bolts to fix the formwork position. However, the steel bar anchor rings do not have threaded holes and can only be connected to the formwork bolts by binding and snapping. This not only reduces the formwork support efficiency, but also results in insufficient connection with the formwork bolts, which may cause the formwork to burst when pouring concrete. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a pre-sealed structure for vertical post-cast strips in basements. This pre-sealed structure for vertical post-cast strips in basements, through the first and second reinforcing plates set in the precast slabs, can greatly increase the supporting strength of the concrete slabs and improve the deformation resistance of the precast slabs. Furthermore, through the set embedded pipes and the lifting ring connection holes set in the embedded pipes, it is not only convenient to connect the lifting rings by threads during hoisting, but also convenient to fix the lifting rings to the formwork bolts by threads after disassembly, thereby improving the convenience and firmness of formwork support.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A pre-sealed vertical post-cast strip structure for basements includes pre-cast concrete for the basement, with pre-reserved reinforcing bars and water-stop steel plates fixedly connected internally. A post-cast strip is reserved between two pre-cast concrete sections. A precast slab is fixedly connected to one side of the post-cast strip. A waterproof layer is fixedly connected to the surfaces of the precast slab and the pre-cast concrete. The precast slab includes a concrete slab body, with connecting components on its surface. Horizontal reinforcing bars, vertical reinforcing bars, and reinforcing components are fixedly connected internally to the concrete slab body. This pre-sealed vertical post-cast strip structure significantly increases the support strength of the concrete slab body through the first and second reinforcing plates on the precast slab, while also improving the deformation resistance of the precast slab. Furthermore, the pre-embedded pipes and the lifting ring connection holes on the pre-embedded pipes facilitate threaded connection of the lifting rings during hoisting and allow for easy threaded fixing with the formwork bolts after the lifting rings are disassembled, improving the convenience and stability of formwork support.

[0008] Furthermore, the reinforcing component includes a first reinforcing plate and a second reinforcing plate. The surfaces of the first and second reinforcing plates are fixedly welded to both ends of the transverse reinforcing bars. Both the first and second reinforcing plates are provided with a first plane, a supporting surface, and a second plane. Both the first and second reinforcing plates are steel plates, which can increase the supporting strength and deformation resistance of the precast slab.

[0009] Furthermore, the connecting assembly includes several embedded parts, including anti-slip blocks and embedded tubes. One end of the embedded tube has a lifting ring connection hole, and the inner wall of the lifting ring connection hole is provided with internal threads, which not only facilitates threaded connection with the lifting ring screw, but also facilitates threaded fastening with the template screw later.

[0010] Furthermore, a positioning groove is formed on the surface of the first plane, and the inner wall of the positioning groove is fixedly welded to the surface of the anti-slip block. The positioning groove is polygonal in shape, and the anti-slip block and the positioning groove improve the connection firmness of the embedded pipe.

[0011] Furthermore, the precast slab is made of precast concrete and has a protrusion, abutment and limiting part. The protrusion is located inside the post-pouring strip of the basement and has a limiting function, so that the precast slab does not need to be pre-set with wall tongue and groove when installed.

[0012] Furthermore, the surface of the contact part is fixedly connected to the corner of the pre-poured concrete in the basement. The contact part is an inclined surface, which can increase the contact area and improve the support stability.

[0013] Furthermore, the surface of the limiting part is fixedly connected to the surface of the precast concrete in the basement, which can restrict the closed position of the precast slab.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This scheme can greatly increase the support strength of the concrete slab by setting the first and second reinforcing plates in the precast slab, and at the same time improve the deformation resistance of the precast slab.

[0016] (2) This scheme, through the pre-embedded pipe and the lifting ring connection hole set in the pre-embedded pipe, not only facilitates the threaded connection of the lifting ring during hoisting, but also makes it easy to fix the lifting ring with the template screw thread after disassembly, thereby improving the convenience and firmness of the template support.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 A pre-sealed vertical post-cast strip structure for basements includes pre-cast concrete 1 for the basement. The pre-cast concrete 1 has internally fixedly connected steel bars 11 and a water-stop steel plate 12. The pre-cast steel bars 11 facilitate the connection of the reinforcing bars during the pouring of the post-cast strip 13. A portion of the water-stop steel plate 12 is located within the post-cast strip 13, allowing it to make close contact with the concrete on both sides during the pouring of the post-cast concrete, forming a complete waterproof barrier. A post-cast strip 13 is reserved between the two pre-cast concrete 1s. A precast slab 2 is fixedly connected to one side of the post-cast strip 13. A waterproof layer 14 is fixedly connected to the surfaces of the precast slab 2 and the pre-cast concrete 1. The precast slab 2 includes a concrete slab body 21, and a connecting assembly is provided on the surface of the concrete slab body 21. The connecting assembly includes several embedded parts 5. The anti-slip block 52 and the embedded pipe 51 are provided. One end of the embedded pipe 51 has a lifting ring connection hole 53. The inner wall of the lifting ring connection hole 53 is provided with internal threads, which not only facilitates the threaded connection with the lifting ring screw, but also facilitates the threaded fastening with the template screw later. The concrete slab 21 is internally fixedly connected with transverse steel bars 25, vertical steel bars 26 and reinforcing components. The transverse steel bars 25 and vertical steel bars 26 are bound by iron wire to form a reinforcing steel mesh, which can increase the strength and deformation resistance of the precast slab 2. The reinforcing components include a first reinforcing plate 3 and a second reinforcing plate 4. The surfaces of the first reinforcing plate 3 and the second reinforcing plate 4 are fixedly welded to the two ends of the transverse steel bars 25. The first reinforcing plate 3 and the second reinforcing plate 4 are both provided with a first plane 32, a support surface 33 and a second plane 34. The first reinforcing plate 3 and the second reinforcing plate 4 are both steel plates, which can increase the support strength and deformation resistance of the precast slab 2.

[0027] The surface of the first plane 32 has a positioning groove 31. The inner wall of the positioning groove 31 is fixedly welded to the surface of the anti-slip block 52. The positioning groove 31 is polygonal in shape. The anti-slip block 52 and the positioning groove 31 improve the connection firmness of the embedded pipe 51. The precast slab 2 is made of precast concrete. The precast slab 2 is provided with a protrusion 22, an abutment 23 and a limiting part 24. The protrusion 22 is located inside the post-pouring strip 13 of the basement. The protrusion 22 has a limiting function, so that the precast slab 2 does not need to be pre-set with wall tongue and groove when it is installed.

[0028] The surface of the contact part 23 is fixedly connected to the corner of the precast concrete 1 in the basement. The contact part 23 is an inclined surface, which can increase the contact area and improve the support stability. The surface of the limiting part 24 is fixedly connected to the surface of the precast concrete 1 in the basement, which can limit the closed position of the precast slab 2.

[0029] During construction of the pre-sealed vertical post-cast strip structure of the basement, the horizontal reinforcing bars 25 can be welded and fixed to the first reinforcing plate 3 and the second reinforcing plate 4 first. Then, the vertical reinforcing bars 26 and the horizontal reinforcing bars 25 can be tied together with wire. Next, the anti-sliding block 52 can be installed in the positioning groove 31 and then welded and fixed. Then, concrete can be poured through the precast mold to form the precast slab 2. When the precast slab 2 needs to seal the basement post-cast strip 13, the lifting eye bolt can be threaded and fastened to the embedded pipe 51. Then, the precast slab 2 can be hoisted and placed on one side of the basement post-cast strip 13 and fixed before the waterproof layer 14 is constructed. The first reinforcing plate 3 and the second reinforcing plate 4 set in the precast slab 2 can greatly increase the support strength of the concrete slab 21 and improve the deformation resistance of the precast slab 2. When pouring the basement post-cast strip 13 later, the formwork bolt can be threaded and fastened to the lifting eye connection hole 53 set in each embedded pipe 51. This not only has high formwork efficiency but also high connection strength and facilitates formwork removal.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
