[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0014] Example: Figure 1 , 2 A system for reinforcing a prefabricated composite floor concrete joint template is shown, comprising a fixing rod 1 and a fixing plate 2, wherein the fixing rod 1 is placed at the upper end of the joint and the fixing rod 1 adopts Φ20HRB400 steel bars, the fixing plate 2 is placed at the lower end of the joint and the fixing plate 2 adopts an L-shaped steel plate, a plurality of reserved bolt holes are arranged on the L-shaped steel plate, a joint template 3 is placed between the joint and the fixing plate 2, the thickness of the joint template 3 is 15 mm, a screw 4 is welded to the lower end of the fixing rod 1, the screw 4 is used to connect the joint template 3 and the fixing plate 2, and is fixed by a nut 5.
[0015] In actual application, the reinforcement system is used to make holes (φ20mm) in the joint formwork 3 at a spacing of 800mm, and a position for the screw rod 4 to pass through is reserved. After the formwork frame is erected, the fixing rod 1 is aligned with the reserved hole and placed on the floor. The first distance from the edge of the formwork is ≤300mm, and then it is arranged at a spacing of 800mm. If it collides with the reserved steel bars of the prefabricated composite plate, it can be adjusted left and right, and the position of the formwork can be re-drilled; after the fixing rod 1 is installed, enter the formwork frame, align the fixing plate 2 with the screw rod 4, and place it in the specified position, ensuring that the pressure edge on both sides is not less than 150mm; use an electric wrench to reinforce the screw rod 4, and then check whether the nut 5 is tightened. Concrete can be poured only after acceptance; after the floor slab concrete reaches the strength that can be disassembled, the formwork reinforcement device is removed synchronously with the formwork frame, the upper steel bars are left in the concrete, and the bottom L-shaped steel plate can be reused.
[0016] The top of the system uses φ20HRB400 steel bars as the pressure plate (prefabricated composite plate) load-bearing structure, with 150mm anchors on both sides of the composite plate. The middle part uses φ14 waste screws as the intermediate tension structure, which are welded and fixed at the intersection. The bottom is fixed with an L-shaped steel plate with holes, with 150mm pressure edges on both sides to form an overall stable load-bearing structure.
[0017] The utility model greatly improves the concrete leakage and misalignment between the prefabricated plate and the cast-in-place part, improves the first-time qualified rate of concrete molding quality, reduces the construction period and cost of later repairs, and at the same time utilizes waste and used screws and nuts to save material costs.
[0018] The above are only implementation methods of the present utility model, and are not intended to limit the patent scope of the present utility model. Any equivalent structure made using the contents of the specification and drawings of the present utility model, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present utility model.
