[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a prefabricated composite plate reinforcement device, including a steel bar 1, a bent steel bar 2 is fixedly installed on the upper side of the steel bar 1, a screw rod 3 is fixedly installed on the lower side of the steel bar 1, and a compression strip plate 4 is installed on the threaded sleeve of the screw rod 3.

[0026] Specifically, such as Figure 1 As shown, the steel bar 1 is rectangular, and the prefabricated composite panel is stable and will not shake.

[0027] Specifically, the curvature of the bent steel bar 2 is 120 degrees, and the bending point of the bent steel bar 2 is in an arc shape, which is convenient for placing the steel bars.

[0028] Specifically, such as Figure 1 As shown, the pressing strip 4 is a symmetrical oblique contraction structure, which is easy to rotate and saves materials.

[0029] Specifically, such as Figure 1 As shown, the inclined surface of the pressing strip 4 is provided with protective grooves to avoid rotation and slipping.

[0030] Working principle:

[0031] When in use, the prefabricated composite panels are first placed at a certain interval, and the support columns support the prefabricated composite panels. Then, the steel bars 1 are placed between the prefabricated composite panels, and the support panels are placed under the prefabricated composite panels. The support panels are punched and sleeved on the screws 3. Then, the pressing strips 4 are installed and tightened. The prefabricated composite panels and the support panels are pressed. The apex of the bent steel bar 2 is the same height as the apex of the bent steel bar on the side of the prefabricated composite panel. Steel bars are passed through the position of the bent steel bar 2 and then tied. After the steel bars are tied, concrete is poured. The support panels play a sealing role. After drying, the pressing strips 4 and the support panels are removed, and the excess parts of the screws 3 are cut off.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
