Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, in particular to a prefabricated wall cast-in-place strip reinforcement device. Background Art

[0002] In the vertical structure of prefabricated buildings, the edge columns and corner columns of various shear wall structures are cast-in-place (referred to as vertical cast-in-place strips), and the prefabricated walls that are closely connected to the cast-in-place strips are assembled. Prefabricated walls are assembled at the ends of the cast-in-place strips (corner columns), and cast-in-place strips (straight columns) are arranged on the side of the prefabricated wall away from the corner columns. Before pouring the cast-in-place strips, formwork needs to be installed on both sides of the cast-in-place strips. Independent formwork, primary and secondary keels and tension screws are installed at each cast-in-place strip. The first row of tension screws close to the prefabricated wall needs to be inserted into the prefabricated wall, and the through holes for the tension screws need to be reserved during the deepening and production of the prefabricated wall.

[0003] In actual construction, there is still a phenomenon that the reserved through holes for tension screws on the prefabricated wall are misaligned during the production of prefabricated walls (horizontal deviation, vertical deviation). Once there is deviation in one direction, the template holes cannot correspond to each other during the later installation, resulting in the inability of the tension screws to pass through; new holes are drilled in the template to reinforce the cast-in-place strips, and repeated drilling of holes accelerates the damage of the template and reduces the turnover rate; the construction workers have a weak sense of responsibility, and some of them no longer take reinforcement measures for the misaligned screw eyes in order to speed up the construction progress and facilitate construction. When pouring concrete, mold expansion, mold bursting, and slurry flow occur, and after the mold is removed, problems such as hewing, flatness, and verticality are unqualified. Utility Model Content
