Accurate positioning device for hoisting of prefabricated part

Abstract

The invention discloses an accurate positioning device for hoisting of a prefabricated part, and belongs to the technical field of building construction, wherein the accurate positioning device is mainly used for installing of a prefabricated wallboard. The accurate positioning device comprises a U-shaped vertical plate placed on a lower floor, and an inclined angle is chamfered on the inner edge of the upper end of the U-shaped vertical plate. The U-shaped vertical plate is provided with a positioning pin used for fixing the U-shaped vertical plate to the lower floor. A horizontal positioning bottom plate is fixed to the bottom of the U-shaped vertical plate. A first positioning hole matched with an embedded steel bar of the lower floor is formed in the positioning bottom plate. The accurate positioning device for hoisting of the prefabricated part further comprises a limiting positioning sleeve located on the positioning bottom plate and arranged on the embedded steel bar in a sleeving manner. During using, the embedded steel bar is inserted in an embedded connecting sleeve in the prefabricated wallboard, and the limiting positioning sleeve abuts against the lower end face of the connecting sleeve. The accurate positioning device is simple in structure, accurate in positioning and convenient to install, and the installing efficiency of the prefabricated wallboard is greatly improved. According to a novel grouting structure, the connecting strength between the prefabricated wallboard and the lower floor after construction is also guaranteed, and the construction quality is reliable.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a precise positioning device for hoisting prefabricated components mainly used for installing prefabricated wall panels. Background technique [0002] During the hoisting process of the prefabricated reinforced concrete wall panels of prefabricated structures, the prefabricated reinforced concrete wall panels are placed in place by inserting the lower pre-embedded steel bars on the lower concrete floor into the connecting sleeves reserved in the prefabricated reinforced concrete wall panels, and then pass Grout connection sleeve for connection. During the actual hoisting operation, since the connecting sleeve is located in the recess of the lower part of the prefabricated reinforced concrete wall panel, the relative positional relationship between the steel sleeve and the embedded steel bars in the lower layer cannot be directly observed, so the operator needs to le...

Problems solved by technology

During the actual hoisting operation, since the connecting sleeve is located in the recess of the lower part of the prefabricated reinforced concrete wall panel, the relative positional relationship between the steel sleeve and the embedded steel bars in the lower layer cannot be directly observed, so the operator needs to lean over to find the embedded steel bars in the lower layer The relative position of the connecting sleeve with the steel bar can only be completed after the hoisting operation, which leads to the disadvantage of slow hoisting process of the prefabricated reinforced concrete wall panel
