Problems solved by technology

Tongzhu is a short column sitting on a shunba beam or a corner beam. When an ancient building is subjected to earthquake force or impact force, the acceleration of ground motion will cause uneven subsidence of the foundation, which will easily cause the tenon between the foot of the Tongzhu column and the beam to pull out. out, thereby weakening the overall stability of the wooden frame; and the oversized mortise is likely to cause serious tilting and skewing of the wooden frame; in addition, the mortise is inserted into the mortise, and under the long-term external force, especially the wind load, the beam frame The main horizontal force of the structure, under the action of wind pressure, the mortise may be damaged due to the extrusion of the mortise, or the cross-sectional size of the tenon may be reduced due to the deformation of the mortise and cause sinking, thereby weakening the connection performance between beams and columns. , in the damage assessment of ancient building protection and repair projects, the damage conditions of Tongzhu and beam joints are very serious
Pulling out the tenon of the child column will tilt the beam frame and roll the purlins, which will lead to the instability of the entire beam frame structure
[0005] At present, the mortise and tenon repair of the beam-column joints of large wooden frames in ancient buildings is reinforced with iron nails or angle steel, and the joints of beams, squares, and columns are fixed with iron nails, angle steel, and flat steel to prevent the tenon and tenon from shifting. Although the reinforcement measures have strong rigidity, they are insufficient in flexibility and torsion resistance; in case of uneven subsidence of the foundation or ground vibration, it is easy to cause loosening of the connection between the metal parts and the beams and columns, resulting in the failure of the reinforcement, so that the safety of the joints is still affected. threaten

Embodiment 1

[0026] According to construction engineering practice and earthquake damage investigation, the seismic performance of short columns is relatively weak. When the foundation of ancient buildings is unevenly settled or encounters earthquakes, explosions, impact forces, typhoons, etc., the mortise poles at the joints of Tongzhu column feet and Shunba beams will It is easy to pull out, causing the child column to tilt and the beam frame to flash; this patented technology can be used for reinforcement treatment when the joint between the child column and the Shunba beam is pulled out or the tenon is damaged.

[0027] (1) Add a wooden component at the joint between the top of the Shunba beam and the double tenon at the foot of the child column, and open a dowel with a rectangular section in the middle of the wooden component, and the thickness dimension is the same as the distance between the double tenons at the foot of the child column. The length is equal to the column diameter of ...

Embodiment 2

[0031] Another site where the anti-seismic performance of ancient buildings is weak is the joint between the corner beam and the foot of the child column. The corner beam is located at the corner of the ancient building plane. According to the earthquake damage investigation, the earthquake damage of the corner column is heavier than that of the inner column, and the earthquake damage of the short column is heavier than that of the ordinary column. The child column here is both a corner column and a short column, so the earthquake damage at this node is the most serious. This patented technology can be used to reinforce the corner beam and child column joints. The reinforcement steps are the same as above. The wooden component and the child column base can be connected with tenon and tenon to strengthen the tie force between the corner beam and the child column foot in the horizontal direction. Strengthen the overall performance and anti-torsion performance of the angle beam ...

Abstract

The invention relates to a reinforcement treatment structure for a joint of a squat queen post and a beam of a historic building. A base of the squat queen post is clamped on the beam by virtue of a wood component, a double tenon is arranged on the base of the squat queen post, a double tenon mortise matched with the double tenon is formed in the beam, and reinforcement is carried out without adopting an iron clasp nail, flat steel or angle steel on the basis that the original material and construction technology are not changed, and only a wood structure is adopted for carrying out reinforcement treatment on the joint of the squat queen post and the beam of the historic building.

Description

technical field [0001] The invention belongs to the protection and repair technology of the column and beam joint structure of the ancient building, and specifically relates to the reinforcement treatment structure of the column and the beam joint of the ancient building. Background technique [0002] Tongzhu is a large wooden component of an ancient building. There are mainly the following explanations for Tongzhu: [0003] (1) In Qing-style architecture, Tongzhu is a general term for small and short columns to distinguish beams and columns, such as long columns such as eaves columns and gold columns. (2) The eaves columns on the upper platform of the pavilion-style building are also called "platform child columns". The diameter of the "children's pillar" of the large-scale building is 6.6 buckets. (3) Tongzhu, also known as "lantern column", is located on the Shunba beam and the corner beam. It belongs to the list of short columns, and its column feet are usually made of...
