Problems solved by technology

[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

Embodiment 1

[0017] Due to factors such as uneven foundation settlement or rollover of eaves and purlins in the outer corridors of ancient buildings, the tenons between the pointed beams and eaves columns are easily pulled out. This patented technology can be used for reinforcement. A wooden component is added above the joint between the pointed beam and the eaves column, and one end is opened with a dovetail tenon, which is inserted into the eaves column to strengthen the horizontal tie force between the eaves column and the eaves column. Open a 20x20 mortise at the position corresponding to the pointed beam and the horizontal tie piece, and fix the pointed beam and the horizontal tie piece with a wooden bolt with a cross-section of 20x20. Fix the flat steel fasteners on the body to strengthen the stiffness of the beam-frame joints and the bending resistance of the beam.

Embodiment 2

[0019] The interspersed Fang in the verandah of ancient buildings, one end of which is inserted into the eaves column, and the other end is inserted into the gold column. Both ends are straight tenons, which are easier to pull out. This patented technology can be used for reinforcement. A wooden member is added above the connection between the interspersed square and the eaves column and the gold column. One end is opened with a dovetail tenon, and it is plugged with the eaves column or gold column to strengthen the eaves column or gold column and the interspersed frame. Horizontal tie force, and then open a 20x20 mortise at the position corresponding to the interspersed square and the horizontal tie, and fix the interspersed square and the horizontal tie with a wooden bolt with a cross-section of 20x20. The flat steel fasteners are fixed on the column at the lower end of the column connection to strengthen the stiffness of the beam-frame joint and the bending resistance of the...

Embodiment 3

[0021] The indoor beams of ancient buildings, such as three-frame beams and five-frame beams, are prone to shifting or pulling out of the mortise and tenon of beams and columns due to the rolling of the upper and lower purlins. This patented technology can be used for reinforcement. Add a wooden member above the connection between the frame beam or five frame beams and the gold column, with a dovetail tenon at one end, and insert it with the gold column to strengthen the horizontal tie force between the gold column and the three frame beams or five frame beams, and then in the three frame Open a 20x20 mortise at the position corresponding to the beam or five-frame beam and the horizontal tie piece, and fix the three-frame or five-frame beam and the horizontal tie piece with a wooden bolt with a cross-section of 20x20. The flat steel fasteners are fixed on the column body at the lower end of the joint with the gold column to strengthen the stiffness of the beam-frame joint and t...

Abstract

Disclosed is a steel-wood composited reinforcement device for ancient wood frames. The steel-wood composited reinforcement device needs not to be fixed with iron cramps or angle steel, horizontal displacement of mortises and tenons can be prevented through wood components, and bending resistance of beams and columns can be improved through steel fasteners. The steel-wood composited reinforcement devcie is high in flexibility, shock resistance and twisting resistance; with the reinforcement technology, maintenance and replacement can be achieved, and protection and renovation of the wood structure is benefited.

Description

technical field [0001] The invention relates to the protection and repair of beam frame structures of ancient buildings, in particular to the reinforcement treatment of nodes of beams and columns of ancient buildings on the basis of not changing raw materials and construction techniques. Background technique [0002] 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 of beam frames is very prominent, especially in the outer corridors 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 between the pointed beams, Baotou beams and eaves columns are easily pulled out. Pulling out the tenons will weaken the overall stability of the wooden frame. In addition, if the mortise is pulled out with too large a size, it is likely to cause serious tilting and skewing of the wooden ...
