A kind of repair structure with inlaid inlaid root of ancient building column

Abstract

The invention provides an ancient building post root bezel setting repairing structure, which consists of a post root and a bezel setting post material, wherein a decayed part of the post root is removed; the bezel setting post material is matched with the removed part; the post root and the bezel setting post material are fixed into a whole with the flat surface through screw bolts and flat steel buckle elements; tongue-and-groove mortises are engraved in positions of the notch vertical surface of the post root and the upper top surface of the bezel setting post material; dovetail grooves are engraved in one end part of a tongue-and-groove tenon; the two ends of the tongue-and-groove tenon are inserted into the corresponding tongue-and-groove mortises; and the bezel setting post material and the post root are fixed in an upper part connecting part. On the basis of insisting not changing original materials and construction processes of an ancient building, the rigidity of the bezel setting connecting part needs to be ensured through the post root bezel setting; and the integrality and the anti-seismic performance of the bezel setting part are also enhanced.

Description

technical field [0001] The invention relates to the protection and repair of the single-step beam and column joint structure on the mountain surface of an ancient building, and specifically refers to the reinforcement and repair of the column roots of the ancient building without changing the raw materials and construction technology. Background technique [0002] A column is a component that bears the upper load vertically in a large wooden frame of an ancient building, and it is one of the most important components that constitute a building. The pillars are in contact with the ground or exposed to the outdoors all the year round, and are eroded by wind and rain, so they are very easy to decay. The wooden pillars concealed in the wall are more likely to decay due to damp, poor ventilation and other reasons. Most of the decay of wooden pillars occurs at the root. In this case, it is necessary to make partial repairs to the decayed part. There are two ways to deal with it:...

AI Technical Summary

Problems solved by technology

[0004] Although this traditional method of enclosing the column root has a certain degree of rigidity, the integrity and anti-seismic performance of the overlapping parts are insufficient, and the phenomenon of displacement of the stubble part is very likely to occur, resulting in uneven stress on the column root. Uniform subsidence or ground vibration can easily cause the stubble-wrapped part of the column to loosen and shift in the up and down or left and right directions, resulting in failure of the reinforcing iron hoop, thus threatening the safety of the joints

Secondly, the overlapping parts are welded with iron hoops, and the iron hoops are easy to rust, and this irreversible reinforcement technology is not only not conducive to the maintenance or replacement of reinforcements, but also not conducive to the protection of columns.
