Description

Technical Field

[0001] This utility model relates to the field of building wall technology, and in particular to a waterproof structure for post-cast strips on basement exterior walls. Background Technology

[0002] In construction engineering, a post-cast strip refers to a temporary strip-shaped gap reserved in a concrete structure. It is primarily used to release stress through phased construction, prevent structural cracking, and ensure overall integrity. During construction, the main structure on both sides is poured first, leaving a specified width. After deformation stabilizes, a second pour of micro-expansion concrete is used to seal the gap, followed by enhanced curing.

[0003] The structure and purpose of a basement dictate the importance of waterproofing, making proper waterproofing a crucial issue. The post-cast strip area is particularly challenging. Because a construction joint exists between the post-cast strip and the shear wall, and both the basement and the post-cast strip are constructed with waterproof concrete, water will preferentially seep in through this joint. This area is the most difficult to waterproof in the basement's exterior walls.

[0004] In existing technologies, waterproofing the gaps in post-cast strips is mostly achieved by adding water-stop steel plates to increase the water penetration path. However, the construction of water-stop steel plates is difficult and cumbersome. They need to be welded to the external wall reinforcement, which can easily damage the external wall reinforcement. Furthermore, the water-stop steel plates are difficult to seal, and if leakage occurs, secondary cleaning of the leakage is required, which increases the amount of construction work and the difficulty of construction.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0021] See Figure 1 and Figure 2This utility model provides a waterproof structure for a post-cast strip on the exterior wall of a basement. The structure includes a wall 4 with a post-cast strip 3 inside. One side of the post-cast strip 3 protrudes from the wall 4, ensuring that a cover plate 1 can be used to waterproof and fix the contact surface between the post-cast strip 3 and the wall 4 on the outside of the wall 4, thus guaranteeing the waterproof effect of the post-cast strip 3. A fixing component is fixed to the wall 4 on the side of the post-cast strip 3 protruding from the wall 4. This fixing component seals and compresses the gap between the post-cast strip 3 and the wall 4, ensuring the waterproof effect. The fixing component also includes components fixed to the wall... The cover plate 1 on the wall 4 has a groove. The part of the post-pouring strip 3 protruding from the wall 4 is set inside the groove. The cover plate 1 presses and seals the post-pouring strip 3 to ensure the waterproof effect of the post-pouring strip 3. The cover plate 1 is slidably provided with a side sealing element 2 inside the groove. The cover plate 1 and the side sealing element 2 cooperate to seal the side wall of the part of the post-pouring strip 3 protruding from the wall 4. The side sealing element 2 contacts and seals the side wall of the post-pouring strip 3, and the cover plate 1 contacts and seals the rear wall of the post-pouring strip 3, ensuring the sealing of the post-pouring strip 3 in three directions and forming a good sealing surface.

[0022] See Figure 1 , Figure 2 and Figure 3 Preferably, the portion of the post-pouring strip 3 protruding from the wall 4 of this utility model is provided with several waterproof grooves 6. The surface of the grooves that contacts the post-pouring strip 3 is provided with waterproof protrusions 13 corresponding to the waterproof grooves 6. The surface of the side seal 2 that contacts the post-pouring strip 3 is also provided with waterproof protrusions 13. The waterproof protrusions 13 are inserted into the interior of the waterproof grooves 6. Through the cooperation of the waterproof grooves 6 and the waterproof protrusions 13, the waterproof protrusions 13 are inserted into the interior of the waterproof grooves 6, forming a curved sealing surface to prevent moisture from entering the interior through gaps and affecting the waterproofing effect. Simultaneously, the portion of the post-pouring strip 3 protruding from the wall 4 is provided with several waterproof grooves 6. The wall 4 is partially covered with a sealing gasket, which can be made of rubber. When the waterproof protrusion 13 is inserted into the waterproof groove 6, the sealing gasket can be pressed into the waterproof groove 6, thereby creating a pressing and sealing effect between the waterproof protrusion 13 and the waterproof groove 6. The sealing gasket is located between the post-pouring strip 3 and the side seal 2 and the cover plate 1. The side edge of the sealing gasket extends between the side seal 2 and the wall 4, thereby ensuring that the sealing gasket can cover and seal all the gaps in the post-pouring strip 3, ensuring the sealing effect of the post-pouring strip 3.

[0023] In addition, the cover plate 1 of this utility model has a fixing hole 11. The cover plate 1 and the fixing hole 11 are connected by a fixing bolt. The fixing bolt passes through the fixing hole 11 and is fixed to the wall 4, so that the cover plate 1 can be stably fixed to the wall 4. A clamping member 5 is slidably provided inside the groove. One end of the clamping member 5 abuts against the side of the side seal 2 away from the post-pouring strip 3. The side wall of the cover plate 1 is provided with a clamping bolt 7 to clamp the clamping member 5 against the side seal 2. The position of the clamping member 5 can be adjusted by the clamping bolt 7, so that the clamping member 5 can be... The side seal 2 is pressed against the side wall of the post-pouring strip 3 to seal the side wall of the post-pouring strip 3. The side seal 2 adopts an elastic structure such as a soft rubber pad. When the clamping bolt 7 presses the side seal 2, the side seal deforms under force, making the clamping force at the contact point between the side seal 2 and the wall 4 more sufficient. Through the elasticity and expansion of the side seal, the elastic material seals and fills the gap between the post-pouring strip and the wall, thereby blocking the water seepage process from the source and ensuring the sealing effect. This further reduces the high cost and complex process of sealing with a water-stop steel plate.

[0024] See Figure 3 and Figure 4 Furthermore, the cover plate 1 of this utility model has a sliding hole 14 and a threaded hole 12 on its side wall. The clamping bolt 7 is screwed into the inside of the threaded hole 12, which facilitates the sealing of the post-cast strip 3 by rotating the clamping bolt 7. The clamping member 5 includes a push plate 51 that abuts against the side sealing member 2. The outer side of the push plate 51 is provided with a sliding post 52 that cooperates with the sliding hole 14. A thrust spring 53 is provided between the sliding post 52 and the sliding hole 14. The thrust spring 53 ensures that the two push plates 51 move outward. At the same time, the position of the push plate 51 is adjusted by rotating the clamping bolt 7 to clamp and fix the side sealing member 2.

[0025] In this embodiment, combined with Figures 1 to 4 When in use, after the post-pouring strip is poured, the side seal 2 is placed inside the groove, and then the side seal 2 and the cover plate 1 are simultaneously placed on the outside of the post-pouring strip 3. At this time, the cover plate 1 is first fixed to the wall 4 by fixing bolts. After fixing, the position of the clamping bolt 7 is adjusted by rotating the clamping bolt 7. The clamping bolt 7 presses the push plate 51, so that the push plate 51 presses the side seal 2, thereby achieving a fixed seal for the post-pouring strip 3. In order to ensure the sealing effect, a sealing gasket can be placed between the cover plate 1 and the post-pouring strip 3 to achieve a good sealing effect for the post-pouring strip 3.

[0026] In summary, this utility model provides a waterproof structure for a basement exterior wall with a post-cast strip, comprising: a wall with a post-cast strip inside, one side of which protrudes from the wall, ensuring that a cover plate can be used to waterproof and fix the contact surface between the post-cast strip and the wall on the outside of the wall, thus ensuring the waterproof effect of the post-cast strip; a fixing component fixed to the wall on the side of the post-cast strip protruding from the wall, which seals and compresses the gap between the post-cast strip and the wall to ensure the waterproof effect; the fixing component includes a cover plate fixed to the wall, the cover plate having a groove, and the portion of the post-cast strip protruding from the wall being disposed inside the groove, thus ensuring the waterproof effect of the post-cast strip.
