Ancient building wooden column reinforced through tenon-and-mortise embedded steel bar pier connection

Abstract

The invention provides an ancient building wooden column reinforced through tenon-and-mortise embedded steel bar pier connection. The ancient building wooden column comprises a log column and a new pier connection column, the new pier connection column comprises a new column body and a tenon-and-mortise joint, the tenon-and-mortise joint is arranged on the upper part of the top of the new column body in the vertical direction, a mortise opening is formed in the lower bottom face of the log wooden column, the tenon-and-mortise joint is inserted into the mortise opening in the section of the log column, the log column and the pier connection new column are connected together through a mortise and tenon joint and are reinforced through a set of parallel self-tapping screws in the horizontal direction. On the premise that the bearing capacity of the wooden column is guaranteed, the appearance of the log column is not changed much, and the log column is not prone to being affected by the environment.

Description

technical field [0001] The invention relates to the technical field of protection and restoration of ancient buildings, in particular to a wooden column of ancient buildings strengthened by mortise-and-tenon pier joints. Background technique [0002] At present, in the pier connection reinforcement of traditional round wood columns, most of them are reinforced by wrapping with FRP or steel strips. Common forms include FRP ring-wrapped pier joints and steel strips wrapped pier joints. This form of reinforcement mainly uses FRP and steel strips to increase the stiffness of the pier joints to provide the bearing capacity of round timber columns. This form of reinforcement mainly has the following problems: [0003] (1) Since the steel strip is exposed, it is easily affected by the external environment, causing corrosion during use. [0004] (2) After FRP and steel strips are reinforced, because of the large difference in color and wood, it greatly affects the appearance. [...

AI Technical Summary

Problems solved by technology

[0003] (1) Since the steel strip is exposed outside, it is easily affected by the external environment, which causes corrosion during use

[0004] (2) After FRP and steel strips are reinforced, because of the large difference in color and wood, it greatly affects the appearance

[0005] (3) During the use of the round wooden column after reinforcement, the vertical load will produce a certain bias, and the round wooden column reinforced with FRP and steel strips will have a restriction that the pier connection position cannot be too high
