Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated wall panel assembly, specifically to an auxiliary positioning device for prefabricated wall panel assembly. Background Technology

[0002] Precast wall panels are concrete components prefabricated in a factory and are mainly used for the rapid assembly of building walls. During the construction of prefabricated shear wall systems, the wall panel sleeves need to be aligned with the connecting reinforcing bars when hoisting and positioning the wall panels. Due to insufficient visibility at the bottom of the wall panels, ordinary mirrors are often used to assist in providing a clear view so that the wall panel sleeves are aligned with the bottom reinforcing bars.

[0003] An existing precast wall panel auxiliary positioning tool, such as one with patent publication number CN212129980U, hoists the precast wall panel to a safe adjustment position on the working floor. The distance and position of the user from the connecting rebar are visually assessed, and the pitch angle of the observation mirror is adjusted. Holding the first-stage steel pipe of the tool, the observation mirror is moved below the wall panel sleeve. Based on the field of view provided by the tool regarding the wall panel sleeve and the lower connecting rebar, the wall panel sleeve is quickly aligned with the lower rebar. The tool is then removed, completing the wall panel positioning.

[0004] However, this device only uses adjusting bolts to fix the angle of the observation mirror, resulting in poor stability. Utility Model Content

The observation mirror 5 is connected by the connecting frame 4 and moves synchronously relative to the shaft rod 2 by two sets of rotating movable sleeves 3. Then, it is constrained by two sets of hinge frames 6 to move the hinge block 7, so that the telescopic tube 8 and the telescopic rod 9 are rotated accordingly, and the observation mirror 5 is rotated to the corresponding angle in conjunction with the telescopic adjustment. Then, the tightening handle 13 is turned to rotate the tightening screw rod 12. The tightening screw rod 12 is screwed in with the tightening screw sleeve 11 and acts inward to tighten the telescopic rod 9 at this position, so that the telescopic tube 8 and the telescopic rod 9 are relatively fixed, thereby tilting and supporting the observation mirror 5. Then, the user can move the observation mirror 5 to the bottom of the wall panel sleeve by holding the handle structure to provide a field of vision for connecting steel bars and assist in installation.
