Since the formwork is prone to mold expansion during pouring after fixation, the existing fixed structure is prone to displacement during reinforcement after installation. The mold expansion under the action of concrete makes the shear wall easy to deform. At the same time, the reinforcement strength is not high and the ability to bear weight is small.

[0032] It can be understood that: the clamping rod 1 is a U-shaped structure, and the clamping rod 1 is made of scrap steel bars from the construction site. The scrap steel bars from the construction site are folded and bent into a U-shaped structure. When bending the scrap steel bars, the bending curvature can be set according to actual conditions. The reinforcement 2 is clamped on the clamping rod 1, so that the reinforcement 2 is fastened between the U-shaped clamping rods 1. At the same time, a threaded rod 3 is threadedly penetrated on the reinforcement 2, and the threaded rod 3 also penetrates the casting formwork. The threaded rod 3 is fixed to the casting formwork at the other end by a nut, so that the reinforcement 2 fixes the clamping rod 1 to the casting formwork, and then the clamping rod 1 is fastened by turning the nut, thereby better reinforcing the casting formwork.

[0033] The embodiment of the utility model provides a clamp for reinforcing and preventing the cast-in-place formwork from expanding. The clamping rod 1 is set to be a U-shaped structure, and the reinforcing member 2 is clamped on the clamping member, thereby combining the clamping rod 1 and the clamping member together. Secondly, the clamping rod 1 and the reinforcing member 2 are fixed to the casting formwork according to the threaded rod 3, so that the connection between the clamping rod 1 and the casting formwork is tighter under the action of the threaded rod 3 and the reinforcing member 2, and the formwork is more reinforced and can withstand a greater weight. It is easy to install and has a simple structure. At the same time, the materials used in manufacturing are simple, which saves more materials and thus saves budget.

[0034] According to the construction cast-in-place formwork reinforcement and anti-expansion formwork clamp provided by the embodiment of the utility model, a limiting plate 10 is provided on the clamping rod 1, and the limiting plates 10 are combined on the clamping rod 1 to form a plurality of limiting areas 11, and the plurality of limiting areas 11 are vertically combined in groups of two on the clamping rod 1.

[0035] Figure 1 and Figure 3 A clamp for reinforcing and preventing the expansion of cast-in-place formwork for buildings is implemented in the present invention. A limiting plate 10 is arranged on the clamping rod 1. The limiting plate 10 is a circular ring structure, and the limiting plate 10 is fixedly welded to the clamping rod 1.

In this embodiment, they are vertically combined in pairs, and then the two ends of the bent combination of the clamping rod 1 are combined together. At the same time, the number of combinations is preferably two groups, and the two groups are respectively arranged at the two ends of the clamping rod 1 that are not bent.

[0036] The embodiment of the utility model provides a clamp for reinforcing and preventing the cast-in-place formwork from expanding. A limiting plate 10 is set. A plurality of limiting plates 10 are set on the clamping rod 1. Two limiting plates 10 are combined as a group to form a limiting area 11.

At the same time, two groups of combined limiting areas 11 are preferably set, so that the two ends of the clamping rod 1 are more balanced after fixation, and the force can be better applied to the casting formwork.

[0037] According to the construction cast-in-place formwork reinforcement and anti-expansion formwork clamp provided by the embodiment of the utility model, clamping grooves 21 are opened at both ends of the reinforcement member 2, and the clamping grooves 21 are arc-shaped structures.
