Description

Technical Field

[0001] This utility model belongs to the field of post-pouring strip protection technology, and more specifically, it relates to a post-pouring strip protection device for the exterior wall of an underground garage. Background Technology

[0002] In the construction of the exterior walls of underground parking garages, post-cast strip technology is widely used to prevent potential harmful cracks caused by uneven shrinkage or settlement of the cast-in-place reinforced concrete structure. This technology temporarily divides the exterior walls of the underground parking garage into multiple parts, allowing the interior of the exterior walls to shrink naturally. After a period of settling, the construction joints in the exterior walls of the underground parking garage are then filled with concrete, thereby reconnecting the originally scattered structural parts into a whole.

[0003] Currently, the delay in the pouring time of post-pouring strips has caused significant inconvenience to construction. In particular, the post-pouring strips of the exterior walls of underground parking garages, located in the underground area, will directly hinder the backfilling work if they are not closed for a long time, thus delaying the overall construction period. In addition, if the post-pouring strips are left open for a long time, the risk of absorbing debris will be greatly increased, which will not only contaminate the post-pouring strips themselves, but also have an adverse effect on the steel bars reserved inside, thus interfering with subsequent pouring operations. Therefore, in order to ensure the quality and safety of the post-pouring strips, it is urgent to adopt effective protective devices to shield and protect them. Summary of the Invention

[0026] The specific usage and function of this embodiment are as follows: In this utility model, during use, the bottom protective plate 201 is placed between two sets of outer wall sections 1, allowing the connecting seat 401 to slide inside the connecting seat 302. The hexagonal socket bolt 304 is passed through the connecting hole 402 and screwed into the threaded hole 303, thus fixing the connecting screw 403. Then, the threaded cylinder 404 is rotated via the handle 406, causing both sets of threaded cylinders 404 to rotate simultaneously via the sprocket 407 and chain. This causes the two sets of threaded cylinders 404 to shorten the distance between the fixed crossbeam 405 and the protective plate 201 via the connecting screw 403, clamping the outer wall section 1 between the protective plate 201 and the fixed crossbeam 405. This allows the nail body 408 to be inserted into the outer wall section 1, fixing the bottom protective plate 201. Then, the protective plates 201 are fixed sequentially from bottom to top. The water-swellable sealing strip 204 slides into the waterproof groove 205, thereby ensuring the waterproof effect between the two sets of protective plates 201 by utilizing the water-swellable sealing strip 204 and the waterproof groove 205; the water-swellable sealing mortar is poured into the connecting groove A101 and connecting groove B202 to form mortar columns 203; when it is necessary to pour concrete between the two sets of external wall 1 and the post-pouring strip, the internal hex bolt 304 is unscrewed out of the threaded hole 303, so that the connecting seat 302 and the connecting seat 401 are separated, thereby allowing the fixing mechanism 4 to be disassembled and reused; then the concrete is poured between the two sets of external wall 1 and the post-pouring strip, so that the newly poured concrete is tightly connected to the protective plate 201 through the reinforcing steel bar 206, the reinforcing plate 305, and the reinforcing hole 306.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
