Construction method for controlling embedded quality of foundation bolt embedded part

Abstract

The invention provides a construction method for controlling the embedded quality of a foundation bolt embedded part. The construction method comprises the steps that 1, the bolt embedded part is manufactured; 2, after lower concrete is poured firstly, bottom foot sections of a fixing frame and a wire frame are embedded in the pouring process; 3, an upper frame body of the fixing frame and a coilholder are welded, four stand columns of the upper frame body of the fixing frame and the bottom foot sections of the upper frame body are welded and fixed one by one after the lower concrete is finally set, and the height of a top beam of the fixing frame is equal to the designed height of a bolt embedded part steel board; four stand columns of the upper frame body of the coil holder are welded and fixed to the bottom foot sections one by one, and the top beam of the coil holder is higher than the designed height of the bolt embedded part; 4, the axis projection of the embedded part is performed, and an axis mark is made at the top of the coil holder; 5, the bolt embedded part is placed on the fixing frame, and the axis, the elevation and the perpendicularity of the bolt embedded part areadjusted; and 6, upper concrete is poured, the exposed part of the coil holder is cut, and anti-rust treatment on the section is conducted. According to the method, after rolling pouring is carried out, the position of the bolt embedded part is not affected, and the position accuracy of the embedded part is remarkably improved.

Description

technical field [0001] The invention belongs to the technology of anchor bolts in steel structure buildings, and in particular relates to a construction method for pre-embedded quality control of embedded parts of anchor bolts. Background technique [0002] At the current level of installation technology for large embedded parts, the pre-embedded quality problems of steel plate embedded parts are still common, especially the pre-embedded quality of large-sized embedded parts. The current construction method of the anchor bolt embedded parts is: before concrete pouring, the embedded parts are connected and fixed with the steel bars, and concrete pouring is carried out after forming a whole. In the process of pouring concrete, it is inevitable that the external force of vibrating the concrete will cause the displacement of the steel bar, which will lead to the deviation of the position of the embedded parts. Once the axis and elevation deviation of large embedded parts is too...
