Description

Beam column node for prefabricated PEC structural system Technical Field The utility model relates to the technical field of assembly type building engineering, in particular to a beam column node for a prefabricated assembly type PEC structure system. Background The partially coated steel-concrete composite structure (PEC structure) is a composite structure formed by binding steel bars between flanges of H-shaped steel and filling concrete, and is applied to the fields of high-rise buildings, large-span structures, engineering reinforcement and the like due to the advantages of high bearing capacity, good ductility, excellent fire resistance and corrosion resistance and the like. The beam column node for the prefabricated PEC structural system is disclosed as the publication number of CN214696131U, and the device is assembled on site after being prefabricated by a factory, but because the prefabricated PEC beam assembly has a certain weight, when the prefabricated PEC beam assembly is installed on a prefabricated PEC column, after the prefabricated PEC beam assembly is lifted, holes on the prefabricated PEC beam assembly are aligned with mounting bolts, and repeated adjustment of staff is required to align all holes with the bolts, so that the overall efficiency is poor. Disclosure of utility model The present utility model aims to provide a beam column node for a prefabricated PEC structural system, which solves the problems set forth in the background art. In order to achieve the aim, the utility model provides the technical scheme that the beam column node for the prefabricated PEC structural system comprises prefabricated PEC columns and prefabricated PEC beam assemblies, wherein auxiliary mechanisms are arranged on the surfaces of the prefabricated PEC beam assemblies, and fixing bolts and nuts are arranged on the prefabricated PEC columns; The auxiliary mechanism comprises: The fixing frames are provided with two groups, and the two groups of fixing frames respectively support the guide rods and the screw rods; the limiting plate is used for limiting the prefabricated PEC beam assembly; The guide rod is used for guiding the limiting plate; and the screw is used for controlling the limiting plate to move. Preferably, the mount is provided with two sets of, two sets of the mount is all fixed on the surface of prefabricating PEC crossbeam assembly, the guide bar is fixed in a set of the inboard of mount, the screw rod runs through another group the mount and rotates with the mount and be connected, the screw rod runs through limiting plate and with limiting plate threaded connection, the guide bar runs through limiting plate and with limiting plate sliding connection, the left side of screw rod is fixed with the knob, rotates through rotating the knob, and control screw rod rotates, can make limiting plate remove to control limiting plate and the fixing bolt and the nut that pass prefabricating PEC crossbeam assembly are contradicted, thereby transversely restrict prefabricating PEC crossbeam assembly and can not take place horizontal aversion, when convenient prefabricating PEC crossbeam assembly butt joint installation, guaranteed prefabricating PEC crossbeam assembly's stability.
