Connecting structure of pre-buried steel anchor box

Abstract

The invention discloses a connecting structure of a pre-buried steel anchor box. The connecting structure is arranged on a positioning bar mat between a steel structure pier or a column and a foundation, and comprises a steel anchor box. The steel anchor box comprises a bottom plate, web plates arranged on the side surfaces of the bottom plate and a steel anchor box top surface flange plate arranged on the top surfaces of the web plates; line cones are arranged at corners of the bottom surface of the steel anchor box top surface flange plate and the line cones are suspended to determine the perpendicularity of the steel anchor box; measuring points are arranged at corners of the top surface of the steel anchor box top surface flange plate and coordinates and elevations of the measuring points are measured to determine the levelness and the center position of the steel anchor box top surface flange plate, so that the steel anchor box is positioned accurately. The connecting structure issuitable for a light rail viaduct, solves the problem of high anchor bolt positioning difficulty, heavy workload and low precision in conventional construction, simplifies the construction step of positioning anchor bolts in a construction site and improves the safety stock at reinforced concrete joints.

Description

technical field [0001] The invention relates to the fields of engineering design and construction, in particular to a pre-embedded steel anchor box connection structure. Background technique [0002] In the field of light rail viaducts, steel structure bridges with fast construction and light appearance are more and more widely used. The steel column and the foundation are generally connected by embedded anchor bolts, and the accuracy of the positioning of the embedded anchor bolts is directly related to whether the steel column can be installed correctly, which in turn affects the bridge alignment of the superstructure. [0003] In the past, in the process of pre-embedded anchor bolts, it was generally necessary to locate individual anchor bolts one by one. Since each anchor bolt is independent of each other, the measurement steps during anchor bolt positioning are cumbersome, and large cumulative errors are likely to occur. Verticality and relative position errors are not...
