Problems solved by technology

The pre-embedded anchor bolts of the giant column are arranged in a double-circle tangent pattern, and the number of anchor bolts is large, which makes it difficult to install and locate on site; the site is small, there are many types of anchor bolts, and the length is large, so it is necessary to arrange the site reasonably to reduce secondary mishaps; The pile head reinforcement of the concrete floor conflicts with the pre-embedded anchor bolts of the giant columns, and the anchor bolts cannot be installed; 6 layers of steel mesh with a diameter of 40mm are arranged near the anchor bolts of the giant columns of the concrete floor, and the height of each layer is 50mm. It is necessary to control each layer of civil engineering reinforcement The elevation, especially if the top elevation is too large or too small, will eventually affect the penetration of the anchor bolt cap; when the concrete base plate is poured with large volume of concrete, the anchor bolt will be squeezed, which will affect the final positioning accuracy of the anchor bolt

Embodiment Construction

[0030] The following will be described in detail in conjunction with the accompanying drawings in the embodiments of the present invention. It should be stated in advance that the anchor bolt seat in the text is the final forming structure formed by several anchor bolt rods 2 and several anchor bolt frames 3, and the anchor bolt block It is a semi-finished form that is divided again after the anchor bolt seat is pre-assembled, and it can be a single anchor bolt rod 2, anchor bolt frame 3, or an assembled body of multiple anchor bolt rods 2 and anchor bolt frame 3.

[0031] according to figure 1 , figure 2 , image 3 , the present invention provides following construction steps:

[0032] Step S1, place the mold steel plate 1 horizontally on the flat site, and draw the positioning line of the anchor bolt rod 2 and the anchor bolt frame 3 on the upper surface of the mold steel plate 1;

[0033] Step S2, pre-assemble several anchor bolt rods 2 and a plurality of anchor bolt fr...

Abstract

The invention relates to the field of building construction, in particular to a mega column anchor bolt construction method, mainly including: pre-assembling anchor bolts via a support, grouping according to field conditions, transporting in bulk to a mounting site, measuring, assembling in a whole, performing position correction on the anchor bolts via a positioning socket plate so as to completemega column anchor bolt construction. Therefore, the problem with mounting construction and positioning adjusting process of mega column anchor bolts is solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for giant column anchor bolts. Background technique [0002] The Haikou Tower project includes a super high-rise tower whose outer frame columns and steel plate shear walls are connected by base plates and pre-embedded anchors. The pre-embedded anchor bolt group of this project is divided into two parts: the outer frame column of the tower and the shear wall. In the construction of the pre-embedded anchor bolts of the multi-cavity giant column, the pre-embedded anchor bolts used for the giant column of the outer frame of the tower are located at the four corners of the tower plane. Each corner is composed of 37 sets of anchor bolt brackets. After assembly, the double circle specification is Ф10000×6000mm, and there are 896 anchor bolts of M90×5200mm in total. The shear wall anchor group is located in the center of the tower and is arranged in a nine-squ...
