[0001] The invention relates to the technical field of template engineering, and more particularly to a reinforcement device and an installation method for a template at a node between a column and a beam. Background Art

[0002] During the formwork reinforcement process of circular column-beam nodes, since the side surfaces of the nodes are curved and beams are anchored into the columns in different directions, it is very difficult to reinforce this area during construction, and quality problems such as leakage and formwork expansion often occur during concrete pouring.

[0003] In order to solve the above construction difficulties, the prior art often uses a steel flat belt to reinforce the arc-shaped template outside the beam-column node. In this way, the steel flat belt can only be used once, and the installation of the steel flat belt is extremely inconvenient, which seriously affects the construction progress and construction cost. Summary of the invention

[0015] In some possible implementations,

[0016] The connecting assembly includes multiple groups of horizontal connecting rods for connecting the inner chord and the outer chord, and connecting rods whose one end is connected to the connection between a horizontal connecting rod and the outer chord and the other end is connected to the connection between another horizontal connecting rod adjacent to the horizontal connecting rod and the inner chord; the connecting rods are multiple groups and form a square connecting frame.

[0042] After the concrete pouring is completed, the bottom truss 1 and the vertical reinforcement truss 2 are removed. Compared with the use of rigid flat belts, the present invention can be reused; the installation is simple and convenient, the construction efficiency is high, and the construction cost is greatly reduced;
