Description

Technical Field

[0001] The utility model belongs to the technical field of assembled secondary structure construction of building engineering, relates to a method for positioning and assembling high-rise assembled wall panels, and in particular to a device for transferring and positioning high-rise assembled interior wall panels in a narrow space in a building. Background Art

[0002] Some prefabricated buildings adopt cast-in-place concrete shear wall structure as the main structure. Prefabricated wall panels are assembled in the cast-in-place main structure to complete the assembly of the main secondary structure wall panels. The prefabricated internal partition panels are placed flat on a small flatbed and transported to a designated location for installation. A U-shaped card is set on the bottom surface of the upper floor slab at the installation site. The length of the U-shaped card is 100 mm, and the distance between two adjacent U-shaped cards is equal to the width of the prefabricated wall panel. The installation process is as follows: the lower pipe card is pre-placed at the bottom of the prefabricated wall panel, the prefabricated wall panel is erected by manpower, and the wall panel is pried into the installation site of the wall panel little by little with a crowbar. After fine-tuning and confirmation, the pipe card and the floor slab are nailed to the bottom of the prefabricated wall panel with rivets, and the top of the prefabricated wall panel is fixed with the U-shaped card that has been placed. The reserved joints are sealed with special mortar of the same model and strength. This method of transportation, positioning and installation has the following problems: (1) The prefabricated wall panel is an integral The prefabricated wall panels are pressed and have a length close to the floor height, which is more than 2 meters. When transported by traditional flatbed carts, the prefabricated wall panels need to be placed flat on the small flatbed cart, but there are some narrow spaces on the floor. When the flatbed cart with prefabricated wall panels passes through the narrow space, the prefabricated wall panels are easily bumped and damaged. In some places, the cart transporting the wall panels cannot pass; (2) Before installing the prefabricated wall panels, it is necessary to preset U-shaped cards at the designated installation locations of the upper beams or plates, resulting in the wall panels being installed not being able to be moved and installed in a direction perpendicular to the installation wall, but only along the direction of the wall. This is not only time-consuming and labor-intensive, but also requires many prying times with the crowbar, which will also cause certain damage to the bottom of the prefabricated wall panels, affecting their appearance quality; (3) The maximum weight of the prefabricated wall panels is about 0.4 tons. The method of transporting and positioning the prefabricated wall panels in a horizontal position and then standing them upright has the defects of low efficiency and long installation cycle.
