Self-rearranging mortise and tenon joint

Abstract

The invention discloses a self-rearranging mortise and tenon joint which comprises a wooden beam, a wooden column, a mortise and tenon joint body between the beam and the column and a prestress rib. The wooden beam and the wooden column are connected through the mortise and tenon joint body. The prestress rib penetrates through the wooden beam and the wooden column in the longitudinal direction of the wooden beam. The end portion of the prestress rib is fixed on one side, with the back toward the wooden beam, of the wooden column through an anchor plate, an anchor pad plate and an anchor. The self-rearranging mortise and tenon joint has the ideal advantages that strong bending-resistant capacity and energy-consuming-resistant capacity are achieved, the joint can guarantee structure stability under low quake, structure deforms greatly and structure damage is controlled under high quake, and structure self-rearranging effect is achieved after quake.

Description

technical field [0001] The invention belongs to the field of civil engineering, relates to a mortise and tenon joint, in particular to a beam-column mortise-and-mortise joint of a wooden structure of an ancient building, which is mainly (but not exclusively) used for the reinforcement of beam-column mortise-and-mortise joints of existing wooden structures and after earthquake damage. Repair can also be used for the reinforcement of new wooden beam-column tenon-mortise joints. Background technique [0002] Wooden structures in my country have a long history. From ancient palace buildings, temples and halls to residential buildings, a large number of ancient wooden structures are used. At the same time, the ancient wooden structures are widely distributed, almost all over the country. The famous ancient wooden structures that have been passed down to the present are: Beijing Forbidden City, Shanxi Yingxian Wooden Pagoda, Jixian Dule Temple, Chengde Mountain Resort, etc. The wo...

Problems solved by technology

[0005] 1) Not easy to replace and overhaul

For iron reinforced components, it is difficult to replace them due to corrosion problems, and at the same time brings potential safety hazards; for FRP reinforcement methods, since FRP is pasted on the surface of wooden components with structural adhesive, it is difficult to replace, and it is not easy to repair the reinforced parts. overhaul

[0006] 2) The problem of difficult reset after the earthquake still exists

Traditional reinforcement methods can generally improve the stiffness of mortise and tenon joints, and at the same time have a certain energy dissipation capacity, but after the earthquake, there are still residual deformations, and it is still difficult to restore the position, and the repair cost is also high
