Top cover type hanging bracket device for hoisting prefabricated stand column reinforcement cage compound formwork

Abstract

The invention discloses a top cover type hanging bracket device for hoisting a prefabricated stand column reinforcement cage compound formwork. The top cover type hanging bracket device for hoisting the prefabricated stand column reinforcement cage compound formwork is of a hollowed-out frame body structure and is used for covering the upper part of a prefabricated stand column reinforcement cagewhen the prefabricated stand column reinforcement cage compound formwork is hoisted; the top cover type hanging bracket device comprises a frame rib plate, an upper panel, a lower panel and lifting lugs, wherein the peripheries of the upper panel and the lower panel are correspondingly connected with the frame rib plate, the upper panel is parallel to the lower panel, when the hanging bracket device is used for hoisting the prefabricated stand column reinforcement cage compound formwork, the lower panel is connected with a stand column formwork, the prefabricated stand column reinforcement cage does not exceed the upper panel, the lifting lugs are connected with the frame rib plate and used for vertically lifting the top cover type hanging bracket device, the top cover type hanging bracketdevice is lifted to the top of the prefabricated stand column steel reinforcement cage and further used for turning over and lifting the vertically-lifted prefabricated stand column steel reinforcement cage. According to the top cover type hanging bracket device for hoisting the prefabricated stand column reinforcement cage compound formwork, the position conflict among a hanging point and rigging with the steel bar extending out of the column top is effectively avoided, the deformation of the steel reinforcement cage and the formwork in a hoisting process is avoided, the rigidity is high, the integrity is good, and the operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roof-type hanger device used for mold clamping and lifting of a prefabricated column reinforcement cage. Background technique [0002] The column is an important part of the bridge structure. In the past, the traditional construction method was cast-in-place, the steel bars were bound on site, and the concrete construction relied on the scaffolding platform. However, this process has disadvantages such as long construction period, high construction cost, and difficult quality assurance. With the promotion of construction industrialization, bridge engineering is gradually replacing traditional crafts with prefabricated assembly construction methods, and columns have also begun to be constructed by factory prefabricated on-site installation. [0003] The column is prefabricated in the factory. First, the column reinforcement cage is made, and then the reinforcement ...

AI Technical Summary

Problems solved by technology

However, due to the opening design at the top of the column formwork, it is difficult to control the deformation of the reinforcement cage and the formwork during the turning and lifting process

In addition, the steel bar at the top of the column protrudes from the formwork, causing the lifting point and sling to conflict with the position of the protruding steel bar, making it difficult to set up and inconvenient to operate
