Prefabricating device for embedded steel bar structure of stand column bearing platform and construction method of prefabricating device

Abstract

The invention discloses a prefabricating device of a stand column bearing platform embedded steel bar structure and a construction method thereof, the prefabricating device can prefabricate the stand column bearing platform embedded steel bar structure in a factory, so that the embedded steel bar structure, a pile foundation, a foundation pit and other work are synchronously carried out, the on-site installation and welding time is saved, the construction speed is high, and the efficiency is high; the stand column bearing platform embedded steel bar structure is prefabricated in a factory, the steel bar spacing, the plane position and the verticality of the embedded steel bar structure can be accurately controlled, the quality of embedded parts is guaranteed, some common quality problems caused by field welding are avoided, the positioning precision is effectively improved, and guarantee is provided for the follow-up stand column installation quality. According to the method, the problems that the pre-embedded rib structure of the bearing platform is welded, prepared and installed on site, the alignment deviation of the reserved hole of the stand column is large, and the rework rate is high are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a prefabricated device and a construction method for a pre-embedded steel bar structure of a column cap. Background technique [0002] With the acceleration of urbanization and the continuous construction of urban highways in our country, the number of viaducts will continue to increase in the future. At the same time, as the main technological development direction of viaducts, bridge prefabrication and assembly construction technology has become the development trend of viaducts in the future. It gets rid of the traditional technology of column pouring on site, and adopts factory prefabricated columns, on-site hoisting and pre-embedded reinforcement structure on the cap platform. stitching. At present, the manufacturing process of the pre-embedded reinforcement structure on the cap top is on-site welding, that is, the main reinforcement and stirrups of the pre-em...
