A wood structure beam-column joint mortise and tenon joint reinforcement device

Abstract

The present invention discloses a mortise-and-tenon joint reinforcement device for beam-column joints of a wooden structure, which discloses a reinforcement device that supports and reinforces the mortise and tenon joints through the cooperation and insertion of the main ring frame and the auxiliary ring frame, without drilling, and is easy to operate and use. It is characterized in that there is a socket on the main pressure plate, one end of the main ring frame is connected with one side of the main pressure plate, the main ring frame is composed of a plurality of main ring rods, and one end of the main ring rod is equiangular along the socket distribution, the other end of the main ring rod extends away from the main pressure plate first, and then bends inward, the other end of the main ring rod is pointed, and the diameter of the main ring frame gradually decreases from one end to the other end, One end of the two pairs of screws is symmetrically placed on the other side of the main pressure plate, and there is an included angle between the screws and the main pressure plate, and the angle is 45°. The arc-shaped reinforcing plate is placed on a pair of screws, and the arc The convex surface faces the main pressure plate, and the nut is screwed on the screw rod, and the nut is located on the concave side of the arc-shaped reinforcing plate.

Problems solved by technology

[0002] Mortise and tenon is the main structural method of ancient Chinese buildings, furniture and other equipment. It is a connection method that combines concave and convex parts on two components. The protruding part is called tenon or tenon; the concave part is called tenon or tenon. Mortise and mortise, which are characterized by not using nails on objects, reflect ancient Chinese culture and wisdom, while traditional mortise and tenon structures that do not rely on nails have weak bearing capacity and bending resistance at the mortise and tenon joints , easy to be affected by earthquakes and other vibrations, making the mortise and tenon joints loose, and the existing methods are usually reinforced by angle steel, curved steel plate, U-shaped flat steel and iron nails, but this reinforcement method requires screw drilling at the wooden structure , the punching action will damage the wooden structure at the joint, and it is easy to cause cracks in the wooden structure, which will affect the service life of the wooden structure at the mortise and tenon joints.

[0003] The notification number CN102277979A discloses a wood structure mortise and tenon joint reinforced by energy-consuming curved steel plates, including wooden columns, wooden beams and mortise and tenon joints. The wooden columns and wooden beams are connected by mortise and tenon joints. The angle formed by the connection of wooden beams is provided with an arc-shaped steel plate for reinforcement, and the two ends of the arc-shaped steel plate are respectively fixed on the wooden column and the wooden beam by bolts. This reinforcement structure needs to be carried out on the wooden structure of the tenon joint Drilling can easily cause damage to the wooden structure and affect its overall strength

[0004] The notification number CN206636254U discloses a self-resetting structure reinforced by three-dimensional shape memory alloys with mortise and tenon joints, including wooden columns, and a wooden frame formed by connecting wooden columns and wooden beams through mortise and tenon joints. Two arc-shaped strip-shaped alloy sheets are connected to the inner wall of the vertical intersection of the beams, and two strip-shaped alloy sheets are connected to the wooden column at the mortise and tenon joint and the outer wall of the wooden beam, and the arc-shaped strips are respectively penetrated by wood screws. Shaped strip-shaped alloy sheets and strip-shaped alloy sheets are embedded in wooden columns and wooden beams. When installing this reinforcement structure, it is necessary to drill holes in the beams and columns at the mortise and tenon joints, which is easy to damage them, cause cracks, and affect actual service life
