Problems solved by technology

[0007] The reinforcement methods described in the dot-matrix cross-grain reinforced wood structure mortise and tenon joints (patent number 201410831335.8)" and "insert-type horizontal grain reinforced wood structure mortise and tenon joints (patent number 201410830182.5)" are implanted after the tenon is punched. Round rod reinforcements, or slotting and implanting plates for reinforcement, have the disadvantages of complex procedures and high construction difficulty, and the depth of slotting and drilling is relatively large, which destroys the continuity of the tenon wood fibers and weakens the tenon. The flexural bearing capacity of the tenon makes the tenon easy to break when it is bent
[0008] Applying glue on the tenon surface is also a commonly used reinforcement method, but the plane rubber layer formed by this method has high rigidity but limited bearing capacity. The relative rotation angle of the nodes is very small

Abstract

The invention discloses a mortise-tenon joint enhancing device and a using method thereof. The mortise-tenon joint enhancing device comprises a wood column, a wood beam and a rubber layer with bulgedrubber blocks, wherein a mortise is arranged on the wood column; a tenon is arranged on the end of the wood beam; the tenon is matched with the size of the mortise; the tenon is inserted into the mortise; the rubber layer is arranged at a part, contacting with the mortise, of the tenon and is used for fixing the tenon and the mortise; counterbores are arranged on the outer side surface of the tenon and / or the inner side surface of the mortise; the bulged rubber blocks correspond to the positions of the counterbores; and the shapes of the bulged rubber blocks are matched with the shapes of thecounterbores. The mortise-tenon joint enhancing device has the characteristics that the rubber layer with the bulged rubber blocks can effectively prevent a mortise-tenon joint from being damaged by the transverse shearing force, and the mortise-tenon joint enhancing device has simple structure and low manufacturing cost and takes short time.

Description

technical field [0001] The invention relates to the technical field of mortise and tenon joints, in particular to a mortise and tenon joint reinforcement device and a method for using the same. Background technique [0002] Wooden structure is an important form of ancient Chinese architecture, and the use of mortise and tenon joints as the connection method between wooden components is one of the main features of ancient Chinese wooden structure architecture. The mortise and tenon joint is a connection joint formed by the combination of concave and convex between wooden components. The protruding part is called the tenon, and the concave part is called the mortise. [0003] The properties of mortise and tenon joints between beams and columns of timber structures have a very important influence on the load-bearing performance of the overall structure. On the one hand, under vertical load, the mortise and tenon joints between beams and columns resist the vertical load transmi...
