[0002] A post-cast strip is a concrete strip of a certain width, reserved within beams, slabs, walls, and other structures, poured after a certain period of time to accommodate factors such as temperature fluctuations, concrete shrinkage, and uneven structural settlement. Post-cast strips can be supported in a variety of ways. Traditionally, formwork support frames remain in place and are removed after the post-cast strip is sealed. However, due to the late pouring time of post-cast strips, the frame rental costs are high. Traditional support frames also occupy a large area, making them inconvenient for other projects such as basement decoration and integrated plumbing. Utility Model Content

[0006] In a preferred embodiment, the distance between two adjacent groups of square steel tube supports along the post-cast strip is ≤3m, and the inner side of the square steel tube supports is 200mm away from the edge of the post-cast strip plate.

[0007] In a preferred embodiment, anchor bars are symmetrically welded to the four corners of the embedded plate. The anchor bars are first-class steel bars with a diameter of 20 mm and a bent hook.

[0008] In a preferred embodiment, the connecting steel pipe includes multiple horizontally arranged first connecting steel pipes, which are evenly spaced along the square steel pipe support. Two second connecting steel pipes are fixed under each first connecting steel pipe, and the two second connecting steel pipes are symmetrically arranged on both sides of the square steel pipe support.

[0015] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0016] Example 1

[0017] like Figures 1 to 2 As shown, the support system for the post-cast strip of the floor slab of the present invention includes: a post-cast strip 3, a square steel pipe support 1, an embedded plate 2 and a connecting steel pipe 6. The embedded plate 2 is fixed in the lower concrete floor slab 4, and the bottom of the embedded plate 2 is welded and fixed to the steel bars of the lower floor slab via anchor bars 21. Multiple groups of square steel pipe supports 1 are evenly spaced on both sides of the post-cast strip 3. There are two square steel pipe supports 1 in each group, and the two square steel pipe supports 1 are symmetrically arranged on both sides of the post-cast strip 3. The lower end of each square steel pipe support 1 is fixed to the embedded plate 2, and the upper end extends into the upper concrete floor slab 5, thereby supporting the floor slabs on both sides of the post-cast strip. Connecting steel pipe 6, multiple connecting steel pipes 6 fixedly connect the square steel pipe support 1 to the surrounding frame 7.
