An installation method of a foundation anchor bolt combination support frame for steel structure shear walls and outer frame column feet of super high-rise buildings

Abstract

The invention discloses a mounting method for a sill anchor combined support frame for a steel structure shear wall and an outer frame column base of a super high-rise building. The method comprises the following steps of: S1, paying off at the position of the sill anchor combined support frame after civil foundation bed construction is finished; S2, mounting a transition rack at a proper position; S3, assembling an anchor bolt stock, an anchor bolt and an anchor bolt penetrating rack into an anchor bolt component, and placing the anchor bolt component on the transition rack; S4, preserving slot templates on a steel plate wall or a steel column foot base anti-shear component; S5, performing a primary calibration on the perpendicularity, the planimetric position and the anchor bolt top elevation of the overall anchor bolt component; S6, performing a secondary calibration on the perpendicularity and the elevation of the anchor bolt in the anchor bolt component before pouring concretes; and S8, pouring building foundation concretes. The mounting method has the advantages of assembling the sill anchor combined support off site so as to reduce in-site cross operation, flexibly adjusting the sill anchor combined support according the practical situation on site, greatly improving the construction efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of super high-rise building engineering construction, in particular to an installation method for an anchor-bolt combination support frame used for super high-rise building steel structure shear walls and outer frame column feet. Background technique [0002] Steel structures are known as "green buildings" for their light weight, high strength, and low environmental pollution; they are also known as "sustainable buildings" because of their high material recovery rate and convenient recycling. In recent years, with the continuous improvement of design level and construction technology, super high-rise steel structure has been developed rapidly. The cross-section of the column foot members of this type of steel structure is very large, and there are dozens or hundreds of anchor bolts used for each column foot, forming a bolt group, and the cross-section and length of the anchor bolts are also large, and the si...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to improve the defects existing in the existing construction methods and provide a method for installing the anchor-bolt combined support frame for the steel structure shear wall and outer frame column feet of super high-rise buildings; The method has the advantages of being able to assemble the anchor-bolt combination support frame off-site to reduce on-site cross operations, and flexibly adjust the anchor-bolt combination support frame according to the actual situation on site, which can greatly improve construction efficiency; and the ground used in this method The lower part of the foot-anchor combination support frame is a transition frame whose height can be set arbitrarily, and the upper part is used to fix the anchor bolt sleeve frame and anchor bolt perforation frame, which can be quickly installed, docked, adjusted, and fixed anchor bolts are very suitable for deep foundation reinforcement Dense, complex construction environment such as sump pits and elevator shafts exist locally
