Description

Technical Field

[0001] The invention relates to the technical field of prefabricated wall panel installation, and more particularly to a prefabricated concrete wall panel auxiliary installation device and a construction method. Background Art

[0002] Precast wall panels are the abbreviation of building partition strips, which are made of lightweight materials or lightweight structures, with mortise and tenon joints and joint grooves on both sides. During the laying of precast concrete wall panels, one construction worker is required to support the precast concrete wall panels to be fixed, and another construction worker applies cement to the joints of the two adjacent precast concrete wall panels. However, during the process of applying cement, the construction worker supporting the precast concrete wall panels may shake, causing the precast concrete wall panels to be fixed to shift, affecting the cement connection effect at the joints, and even the collapse of the precast concrete wall panels to be fixed, affecting the construction progress.

[0003] The existing auxiliary installation device still has the following problems in actual use:

[0004] When installing precast concrete wall panels, since the ground is not level, the wall panels need to be leveled and the bottom of the wall panels need to be elevated. Existing auxiliary installation devices only clamp and fix the precast wall panels through strip extrusion plates. Due to the limitation of the flatness of the ground, the leveling work of the precast concrete wall panels is affected. At the same time, the precast concrete wall panels cannot be elevated, which affects the overall flatness of the precast concrete wall panels.

[0005] Therefore, how to provide a precast concrete wall panel auxiliary installation device that can solve the above-mentioned technical problems is one of the technical problems that urgently need to be solved in this field. Summary of the invention

The purpose is to solve the problem that when the existing precast concrete wall panel is installed, the wall panel needs to be leveled because the ground is not level, and the bottom of the wall panel needs to be raised. The existing auxiliary installation device only clamps and fixes the precast wall panel through a strip extrusion plate, which is limited by the flatness of the ground, thereby affecting the leveling work of the precast concrete wall panel. At the same time, the precast concrete wall panel cannot be raised, thereby affecting the technical problem of the overall flatness of the precast concrete wall panel.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:
