Description

Technical Field

[0001] This utility model relates to the technical field of post-settlement pouring strips for basement exterior walls, specifically a pre-sealing structure for post-settlement pouring strips in basement exterior walls. Background Technology

[0002] Currently, the most effective solution for reducing the adverse effects of shrinkage in concrete structures, applicable both domestically and internationally, is to adopt crack prevention measures. Specifically, the commonly used construction method in my country is to set up post-pouring strips. Post-pouring strips are temporary construction joints left at corresponding positions in the foundation slab, walls, and beams during building construction to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage. According to design or construction specifications, these joints temporarily divide the structure into several parts. After the internal shrinkage of the components, the concrete at the construction joint is poured after a certain period of time to connect the structure into a whole.

[0003] In existing construction methods for pre-sealing post-cast strips in basement exterior walls, fixing clips are typically installed on the side of the baffle facing the post-cast strip. When the baffle contacts the wall of the post-cast strip, the fixing clips are fitted onto the reinforcing bars within the wall to secure the baffle. However, the distribution of reinforcing bars within the wall of the post-cast strip is not uniform. To ensure a tight fixation, the baffle needs to be prefabricated to ensure a tight connection between the clips and the reinforcing bars, increasing construction costs. Furthermore, because the reinforcing bars within the wall of the post-cast strip are flexible, they can deform over time when connected to the clips, leading to gaps between the baffle and the wall, ultimately affecting the sealing of the post-cast strip. Therefore, those skilled in the art provide a construction method for pre-sealing post-cast strips in basement exterior walls to solve the problems mentioned in the background. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a pre-sealing structure for the post-cast strip of a basement exterior wall to resolve the issue of inconsistent reinforcement distribution within the post-cast strip wall. In order to ensure tight fixation, prefabrication of baffles is necessary, ensuring a tight connection between the clamping components and the reinforcement within the post-cast strip wall, which increases construction costs. Furthermore, due to the toughness of the reinforcement within the post-cast strip wall, deformation can occur over time when connected to the clamping components, leading to gaps between the baffle and the wall, ultimately affecting the sealing of the post-cast strip.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-sealing structure for the post-cast strip of a basement exterior wall settlement, comprising an exterior wall, a post-cast strip on the exterior wall, reinforcing bars inside the post-cast strip, a baffle on one side of the exterior wall, a first screw hole in the center of the baffle, a second screw hole around the periphery of the first screw hole, a first six-hole bolt in the first screw hole, a tie rod connected to one end of the first six-hole bolt facing the post-cast strip, pull rings installed at both ends of the tie rod, and a steel rope connected to one end of the second six-hole bolt facing the post-cast strip.

[0008] Preferably, waterproof mortar is provided on both sides of the baffle.

[0009] Preferably, the top of the baffle is provided with a lifting ring, which is concave to facilitate the stacking of the baffles.

[0010] Preferably, the first internal hex bolt is threadedly connected to the first screw hole, and the pull rod is rotatably connected to the first internal hex bolt.

[0011] Preferably, both ends of the steel rope are connected to the second internal hexagonal bolt. The steel rope can pass through multiple reinforcing bars of the inner wall of the post-cast strip. Then, the second internal hexagonal bolt is rotated using tools such as an internal hexagonal wrench, so that the second internal hexagonal bolt moves away from the reinforcing bars of the inner wall of the post-cast strip, so that the steel rope is tightly fitted with the reinforcing bars of the inner wall of the post-cast strip, thereby making the baffle tightly fitted with the outer wall.

[0012] Preferably, the pull ring is slidably sleeved with the steel rope. When the reinforcement of the inner wall of the post-cast strip deforms and the baffle becomes loose, the steel rope can be further contracted by rotating the first inner six-hole bolt, which further strengthens the tightness between the steel rope and the reinforcement of the inner wall of the post-cast strip.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a structure for pre-sealing the post-settlement concrete strip of a basement exterior wall, which has the following advantages:

[0015] Through design, vertical reinforcing bars are installed within the post-cast strip of the exterior wall. A baffle is installed on one side of the post-cast strip. When the baffle is lifted and aligned with the post-cast strip on the exterior wall, a steel cable can pass through multiple reinforcing bars of the post-cast strip. Then, using tools such as an Allen wrench, the second Allen bolt is rotated, moving it away from the reinforcing bars of the post-cast strip, thus ensuring a tight fit between the steel cable and the reinforcing bars. This, in turn, ensures a tight fit between the baffle and the exterior wall. A pull rod with pull rings is connected to the end of the first Allen bolt facing inwards from the post-cast strip. The pull rings at both ends of the pull rod are connected to the steel cable. If the reinforcing bars of the post-cast strip deform and cause the baffle to loosen, rotating the first Allen bolt will further contract the steel cable, further reinforcing the tightness between the steel cable and the reinforcing bars of the post-cast strip.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] This utility model provides a technical solution: a structure for pre-sealing the concrete strip after settlement of the basement exterior wall. Please refer to [link / reference]. Figures 1-4The structure includes an outer wall 1, on which a post-cast strip 2 is provided, and a reinforcing bar 3 is provided inside the post-cast strip 2. A baffle 4 is provided on one side of the outer wall 1, and a first screw hole 402 is provided in the middle of the baffle 4. A second screw hole 403 is provided around the first screw hole 402. A first internal six-hole bolt 6 is provided in the first screw hole 402. A pull rod 7 is connected to one end of the first internal six-hole bolt 6 facing into the post-cast strip 2. Pull rings 701 are installed at both ends of the pull rod 7. A steel rope 9 is connected to one end of the second internal six-hole bolt 8 facing into the post-cast strip 2.

[0023] Waterproof mortar 5 is provided on both sides of the baffle 4. A lifting ring 401 is provided on the top of the baffle 4. The lifting ring 401 is concave to facilitate the stacking of the baffles 4. The first internal hex bolt 6 is threaded into the first screw hole 402. The pull rod 7 is rotatably connected to the first internal hex bolt 6. Both ends of the steel rope 9 are connected to the second internal hex bolt 8. The steel rope 9 can pass through multiple reinforcing bars 3 of the inner wall of the post-cast strip. Then, the second internal hex bolt 8 is rotated using tools such as an internal hex wrench. The movement causes the second inner six-hole bolt 8 to move away from the inner wall reinforcement 3 of the post-pouring strip, so that the steel rope 9 is tightly fitted with the inner wall reinforcement 3 of the post-pouring strip, thereby making the baffle 4 tightly fitted with the outer wall 1. The pull ring 701 is slidably sleeved with the steel rope 9. When the inner wall reinforcement 3 of the post-pouring strip deforms and causes the baffle 4 to loosen, the first inner six-hole bolt 6 can be rotated to further contract the steel rope 9, which further strengthens the tightness between the steel rope 9 and the inner wall reinforcement 3 of the post-pouring strip.

[0024] In this utility model, vertical reinforcing bars 3 are installed in the post-cast strip 2 inside the outer wall 1, and a baffle 4 is installed on one side of the post-cast strip 2. A concave lifting ring 401 is installed on the top of the baffle 4.

[0025] A first screw hole 402 is provided at the middle of the baffle 4, and a second screw hole 403 is provided around the first screw hole 402. A first internal hex bolt 6 is fitted inside the first screw hole 402, and a second internal hex bolt 8 is fitted inside the second screw hole 403.

[0026] Furthermore, the inner ends of two adjacent second internal six-hole bolts 8 are connected to steel ropes 9. When the baffle 4 is lifted and attached to the post-cast strip 2 on the outer wall 1, the steel ropes 9 can pass through multiple post-cast strip inner wall reinforcement bars 3. Then, the second internal six-hole bolts 8 are rotated using tools such as an internal six-hole wrench, causing the second internal six-hole bolts 8 to move away from the post-cast strip inner wall reinforcement bars 3, so that the steel ropes 9 are tightly attached to the post-cast strip inner wall reinforcement bars 3, thereby making the baffle 4 tightly attached to the outer wall 1. Then, the first internal six-hole bolt 6 is rotated. The end of the first internal six-hole bolt 6 facing inwards towards the post-cast strip 2 is connected to a pull rod 7 with pull rings 701. The pull rings 701 at both ends of the pull rod 7 are sleeved with the steel ropes 9. When the post-cast strip inner wall reinforcement bars 3 deform and the baffle 4 becomes loose, the first internal six-hole bolt 6 can be rotated to further contract the steel ropes 9, further reinforcing the tightness between the steel ropes 9 and the post-cast strip inner wall reinforcement bars 3.
