Reinforcement treatment structure for joint of baotou beam and hypostyle column of historic building

Abstract

The invention discloses a reinforcement treatment structure for a joint of a baotou beam and a hypostyle column of a historic building. One end of the baotou beam is a through tenon. The hypostyle column is provided with a baotou beam mortise. The through tenon is inserted into the baotou beam mortise and passes through from the other side of the hypostyle column. A crosser is arranged below the baotou beam in parallel. The crosser is composed of a thin section in the middle and thick sections at the two ends of the thin section, wherein the thin section and the thick sections have the same height. A thin section mortise is formed below the baotou beam mortise. The thin section is clamped into the thin section mortise. The thick sections at the two ends are clamped to the two sides of the hypostyle column. On the basis of not changing raw materials and construction technology, the joint of the baotou beam and the hypostyle column of the historic building is reinforced.

Description

technical field [0001] The invention relates to the protection and repair of the joint structure of the head-holding beam and the gold pillar of the ancient building, in particular to the reinforcement treatment structure of the joint of the head-holding beam and the gold pillar of the ancient building. Background technique [0002] In the large wooden frame of ancient buildings, there are many joints where horizontal members and vertical members intersect. The intersection of the step beam and the gold pillar, etc. At present, in the process of protection and repair of large wooden frames of ancient buildings, the phenomenon of tenon pulling out and tenon damage is very prominent, especially at the joints between the head-holding beams and gold pillars of ancient buildings. The reason is that due to the uneven subsidence of the foundation of ancient buildings or the action of horizontal external forces, the tenons (mostly through tenons) between Baotou beams and gold pilla...

AI Technical Summary

Problems solved by technology

The reason is that due to the uneven subsidence of the foundation of ancient buildings or the action of horizontal external forces, the tenons (mostly through tenons) between Baotou beams and gold pillars are easily pulled out, which will weaken the overall stability of the wooden frame. In addition, if the tenon is inserted into the mortise, under the action of long-term external force, the tenon may be damaged due to the extrusion of the mortise, or the tenon may be damaged due to the extrusion of the mortise. Compression deformation reduces the cross-sectional size of itself and leads to subsidence, thereby weakening the connection performance between beams and columns. Especially in the southern part of my country, the large wooden frames of ancient buildings mostly adopt the piercing beam structure, and the beams and beams are connected by through-tenons, which are suitable for For the part that needs to be tied but cannot be installed by the up and down method, the tenon is often made into a shape of big in and small out, also known as big in and small out. It is high in itself, and the part that goes out is halved according to the part that goes in, so it is easier to pull out the tenon

[0003] The mortise and tenon repair of the beams and mortise and tenon of the existing ancient buildings in my country is reinforced by iron nails or angle steel, and the joints of beams, fang and columns are fixed with iron nails, angle steel and flat steel to prevent the tenon and tenon from shifting. These reinforcement measures Although the rigidity is strong, the flexibility and torsion resistance are insufficient; in case of uneven subsidence of the foundation or ground vibration, it is easy to cause the connection between the metal parts and the beams to loosen, resulting in the failure of the reinforcement, so that the safety of the joints is still threatened
