The upper and lower struts are stretched apart to form a support for the formwork.

Further, the ground is screwed and fixed with a fixing piece, the fixing piece is provided with a hinge ring, and the lower end of the strut is hinged with the hinge ring on the fixing piece.

The technical effect of the present invention is as follows:

1. The formwork of the present invention adopts the inner convex edge and the outer convex edge to reinforce the formwork, and the adjacent formwork is connected by bolts to form a tight and fixed fit at the connecting through holes of the outer convex edge, which is conducive to quick installation to form the required pouring cavity It is especially suitable for the pouring of concrete layers with high pressure such as basements, and the splicing method of the above-mentioned formwork is flexible and can be adapted to various shapes;

2. There are multiple jacks on the formwork. The relatively distributed formwork uses steel bars to pass through the jacks. The two ends of the steel bars have external threads. The two ends of the steel bars are locked on the opposite sides of the formwork with nuts. Left in the concrete layer, the structure of this locking formwork is simple and effective, which can greatly improve the firmness of formwork connection and locking.

3. Arc grooves are distributed laterally on the back of the formwork. Multiple formworks arranged and connected horizontally can be locked by frame rods. The locking parts on the side are connected and locked by T-shaped rods, which can further lock the stirrups of the formwork, thereby improving the bearing capacity of the formwork;

4. The template is equipped with a strut, the upper end of the strut is hinged with the hinge ring, and the lower end is supported on the ground, and the upper strut and the lower strut can be stretched to form a pair of templates when the hydraulic pump is used to deliver hydraulic oil to the hydraulic chamber. The support is tighter, the support is further strengthened for the position where the local bearing capacity is higher, and the expansion and contraction of the upper and lower support rods can be regulated by the hydraulic pump, which is suitable for supports of various lengths.
