High-rise building frame supported sectional steel concrete girder-like structural transfer floor construction method

Abstract

Disclosed is a construction method of the support frame steel concrete girder structure transfer floor for the high-rise buildings, which relates to the high-rise building structural transferring technology. Reinforced plates are welded on a profiled steel girder column flange plate and a profiled steel column flange plate; a profiled steel column stirrup is machined to an open stirrup which is welded on the reinforced plate. A perforation hole used for the stirrup to be inserted into is preset on the web plate of the profiled steel column; an angle table is welded on the profiled steel column flange plate; reinforced steel bars are in lap welding with the angle table. In the intersection of a non-frame girder and the profiled steel girder, the reinforced steel bars disconnect a bent anchor on the profiled steel girder web plate; wall body reinforced plates are generally welded on the upper flange wall body of the profiled steel girder; both sides of the wall body reinforced steel bars are welded on the wall body reinforced plates. Perforation holes used for the stirrup to be inserted into are prearranged on the upper flange of the profiled steel girder for the reinforced steel bar parts of the upper column and the concealed column of the profiled steel concrete girder; tie bars are welded with the tie bar reinforced plates. Spilt bolts are welded on both sides of the profiled steel web plate to reinforce the profiled steel concrete girder mould plate. The construction method of the support frame steel concrete girder structure transfer floor for the high-rise buildings has the advantages that the important technical problem the support frame steel concrete girder structure transfer floor in the construction process of the high-rise buildings is solved; the intensity, rigidity and the vibration resistance of the profiled steel concrete girder are reinforced.

Description

technical field [0001] The invention relates to high-rise building structure conversion technology, and in particular provides a construction method for a frame-supported steel concrete beam structure transfer layer of a high-rise building, which is suitable for a frame-supported steel concrete beam structure transfer layer. Background technique [0002] The transfer floor is an extremely important structure in high-rise buildings. It can ensure the overall safety of the high-rise building. The structure of the transfer floor is different and its construction methods have their own characteristics. Judging from the existing high-rise buildings with transfer floors at home and abroad, the transfer floor structures mainly include beam type, plate type, box type, truss type and vierendeel truss type. There are also some less commonly used forms, such as arched, combined column, wall, indirect, giant frame and so on. The transfer layer of concrete beam structure is the most wid...

Problems solved by technology

[0011] The purpose of the present invention is to provide a construction method for the transfer layer of frame-supported steel concrete beam structure in high-rise buildings, which overcomes the problem that the stirrup passes through the web of the steel beam in the encrypted area of ​​the steel concrete column at the position of the beam-column joint, and the main reinforcement of the steel concrete beam passes through the wing of the steel column. If the ties in the edge and beam pass through the web of the steel beam, it is necessary to reserve holes for the reinforcement on the web, and the wall reinforcement on the steel concrete beam needs to pass through the upper and lower flanges of the steel beam, and it needs to be placed on the steel beam, Reinforcement holes are reserved in the lower flange, and the bottom reinforcement passes through the web of the steel beam at the intersection of the ordinary non-frame beam and the steel concrete beam, the steel beam, and the joint joint of the column. The strength bolt connection makes it difficult to bind the steel bars in the steel concrete beams, it is difficult to support the formwork of the frame-supported steel concrete beams, and it is difficult to reinforce them. A series of technical problems such as reserving reinforcement holes in the flange
