Description

Technical Field

[0001] The utility model relates to a post-casting strip side form device for pre-paving a reverse-adhesive waterproof surface in a basement, and belongs to the technical field of building construction. Background Art

[0002] The post-cast joint is a temporary construction joint left at the corresponding positions of the foundation slab, wall, and beam in accordance with the design or construction specifications. It is designed to prevent harmful cracks that may be caused by uneven shrinkage or settlement of the cast-in-place reinforced concrete structure during construction.

[0003] A post-cast strip side form device for pre-paving an anti-adhesive waterproof surface in a basement disclosed in a Chinese utility model patent with publication number CN209066489U includes a wall and a post-cast strip arranged on the wall. Four connecting blocks are fixedly pre-embedded on the top of the wall. The four connecting blocks are symmetrically arranged on both sides of the post-cast strip, and the tops of the connecting blocks are flush with the top of the wall. The tops of the four connecting blocks are fixedly connected to a cover plate by bolts. A grouting hole connected to the post-cast strip is opened on the top of the cover plate. A sealing mechanism matching the post-cast strip is provided at the bottom of the wall. A plurality of evenly distributed steel bars are provided inside the post-cast strip. The two ends of the plurality of steel bars are respectively fixedly pre-embedded on the wall. Two symmetrically arranged connecting plates are provided on the top of the steel bars. The bottoms of the two connecting plates are fixedly connected to C-shaped clamps.

[0004] In the above reference example, the cover plate needs to be fixed and installed with bolts. For this purpose, connecting blocks that can be connected with the bolts need to be buried on both sides of the post-cast strip. When the cover plate is removed, the connecting blocks also need to be removed. The operation is cumbersome and will leave obvious grooves on the post-cast strip. Therefore, improvement is urgently needed. Utility Model Content

[0005] In order to overcome the shortcoming of complicated disassembly of the existing post-cast strip side formwork device, the utility model designs a post-cast strip side formwork device for pre-paving the reverse-adhesive waterproof surface of the basement, which can reduce the construction requirements and is convenient to operate.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Furthermore, a plurality of strip grooves are provided at intervals on both sides of the top end of the cover plate in the extension direction, and the top ends of the steel wire ropes are clamped and fixed by the second rope clamps after extending out of the strip grooves one by one.

[0009] Furthermore, a plurality of through holes for the steel wire rope to pass through are provided in the extension direction on both sides of the baffle, and the through holes are filled with a rubber sealing ring which is fitted on the steel wire rope.

[0010] Furthermore, a plurality of reinforcing rods which are spaced apart and arranged in parallel with each other are fixed to the bottom end of the baffle plate and the top end of the cover plate.

[0011] Furthermore, a sealing strip is provided at the corner between the post-cast strip body and the baffle.

[0012] Compared with the prior art, the utility model has the following characteristics and beneficial effects:

[0013] The utility model utilizes the cooperation between the steel wire rope, the first rope clamp and the second rope clamp to fix the baffle plate and the cover plate on the upper and lower sides of the post-cast strip respectively, so that there is no need to drill holes on both sides of the post-cast strip to install connecting blocks, which effectively reduces construction requirements and is more convenient to operate. Moreover, the arrangement of the strip groove facilitates disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
