[0032] The baffle 1 can be made of plastic injection molding, and the baffle 1 is arranged on both sides of the post-casting strip 2. The baffles 1 on both sides are symmetrically arranged about the post-casting strip 2, and the facing surfaces of the baffles 1 on both sides are provided with limit grooves 3 along the length direction. The steel cover plate 4 covers the post-casting strip 2, and the two sides of the steel cover plate 4 overlap the corresponding baffle 1; the telescopic component 5 is fixed to the bottom surface of the steel cover plate 4, and the telescopic ends on both sides of the telescopic component 5 are embedded and matched with the corresponding limit grooves 3.

[0033] like Figure 2 and 3 As shown, a docking groove 101 is provided at one end of the baffle 1, and a docking protrusion 102 is provided at the other end. When two adjacent baffles 1 are connected, the docking protrusion 102 at the end thereof is plugged into and matched with the docking groove 101, thereby improving the overall support stability.

[0034] like Figures 1 to 3As shown, the bottom edge of the baffle 1 is provided with a plurality of fixing holes 103 at intervals along the length direction, and the fixing holes 103 are provided with tie screws 6, and the lower ends of the tie screws 6 are fixed with hook plates 7, and the hook plates 7 are against the concrete layers on both sides of the post-casting strip 2; the upper ends of the tie screws 6 are threadedly connected with nuts 8, and the nuts 8 are against the bottom edge of the baffle 1. By rotating the nuts 8, the baffle 1 and the hook plates 7 can be clamped on the concrete layer, thereby achieving the fixing of the baffle 1.

[0035] In this embodiment, the bottom of the limiting groove 3 is provided with anti-skid patterns 301 , and the anti-skid patterns 301 increase the friction force between the limiting groove 3 and the pressing part of the telescopic component 5 to prevent the steel cover plate 4 from moving.

[0036] like Figure 4 and 5 As shown, in this embodiment, the telescopic component 5 includes a sleeve 501, which is fixed to the bottom surface of the steel cover plate 4, and movable rods 502 are inserted at both ends of the sleeve 501, and the movable rod 502 is slidably engaged with the sleeve 501; the movable rod 502 and the sleeve 501 can both be made of square tubes.

[0037] A gear 503 is provided in the middle of the tubular cavity of the sleeve 501, and the gear 503 is fixed on the gear shaft 504. The gear shaft 504 is rotatably connected to the reserved hole on the sleeve 501. Racks 505 are provided on both sides of the gear 503. The gear 503 meshes with the racks 505 on both sides.
