Anti-floating anchor rod structure of raft board

Abstract

The invention discloses an anti-floating anchor rod structure of a raft board. The anti-floating anchor rod structure comprises an anchor rod (1) and is characterized in that two anchor rod ribs (2) having the same length with the anchor rod (1) are symmetrically arranged in the anchor rod (1). The anchor rod ribs (2) are exposed to the outside of the upper portion of the anchor rod (1), short anchor ribs (3) are welded in lateral mode at the upper ends of the anchor rod ribs (2) through the double-face overlapping welding process, and the short anchor ribs (3) are axially parallel to the anchor rod ribs (2). The anti-floating anchor rod structure is simple in structure and ingenious in design, increases the plane operation space of a basic construction stage on the premise that the construction technical requirement of a building base plate is met, and does not need to arrange split head ribs additionally to temporarily support the distributed ribs on the upper surface of the foundation.

Description

technical field [0001] The invention relates to a building foundation structure, in particular to a raft anti-floating anchor rod structure. Background technique [0002] With the rapid development of the current urban modernization process, super high and super large buildings represented by large shopping malls and exhibition halls have sprung up around people's lives. At the same time, the raft plus anti-floating anchor foundation is widely used in this kind of building structure due to its advantages of deep burial, high rigidity, strong integrity, and good earthquake resistance. In engineering, in order to ensure the good overall performance of the foundation structure and make the raft evenly stressed, the anti-floating anchor rods uniformly arranged in the rock foundation are usually reliably tied to the foundation raft. The knot is mainly realized by the anchoring of the anti-floating anchor rod in the raft. The existing anti-floating anchor anchoring method is to ...

AI Technical Summary

Problems solved by technology

[0003] 1. On the engineering plane where the raft is designed, the distribution density of the anti-floating anchors is relatively high. After being made into the form of curved anchors, the use of space in the working face is severely restricted, and it cannot provide basic support for other mechanical equipment and personnel materials. plane working environment;

[0004] 2. Since the top height of the longitudinal reinforcement of the anchor rod is within 1 / 2~2 / 3 of the height of the raft, it does not reach the height of the distribution of the upper skin of the raft, so it is necessary to additionally set the distribution of the horse stool reinforcement to the upper skin of the raft during construction. tendons for temporary support;

[0005] 3. The longitudinal anchor bar of the anchor rod needs to be bent twice, and the forming surfaces of the two bends are required to be kept in the same plane. The technical standard of processing is relatively high, but the processing conditions on site are not convenient for the implementation of such technical requirements
