Novel damping connecting joint suitable for wood structure beam and column connection

Abstract

The invention discloses a novel damping connecting joint suitable for wood structure beam and column connection, and belongs to the technical field of building structures. The novel damping connectingjoint mainly comprises a wood beam (1), wood columns (2), a wood beam penetrating hole way (3), wood column penetrating hole ways (4), penetrating rebars (5), sealing plates (6) and viscoelasticity dampers (7). Aiming at the problems that a conventional wood structure joint is low in connecting strength and poor in durability, after the penetrating rebars (5) are tensioned, prestressing force isapplied, the penetrating rebars (5) are anchored at the two ends of the beam (1), the connecting strength of the wood structure beam and column connecting joint is greatly improved, large loads can beborne, meanwhile under the earthquake reciprocating action, the viscoelasticity dampers (7) suffer from shear deformation, thus, a large amount of earthquake energy is consumed, and the anti-seismicperformance of the structure is improved; the beam and column joint is hidden, and therefore the specific style and feature of the wood structure can be well kept.

Description

technical field [0001] The invention belongs to the technical field of building structures and relates to a novel anti-seismic connection node of a wooden structure. Background technique [0002] China's wood structure has a history of thousands of years, but due to historical reasons, my country's wood resources have been severely damaged, and with the popularity of reinforced concrete and other building materials, concrete structure buildings and steel structure buildings have gradually replaced wood structure buildings and become the mainstay of construction projects. Mainstream, wood structure construction has stagnated for nearly thirty years. In the past ten years, China's timber industry has developed rapidly, and a large amount of high-quality timber at foreign prices has been imported. When people build houses, they are more and more fond of green, healthy and renewable building materials. Therefore, wooden structures have received people's attention again. . [00...

AI Technical Summary

Problems solved by technology

[0005] The technical problem mainly solved by the present invention is to overcome the disadvantages of low connection strength and poor durability of conventional wooden structure joints, and provide a new type of anti-seismic connection node. At the same time, the anti-seismic performance of the structure is improved. Under the action of wind-induced vibration and earthquake, the damping material can quickly dissipate the energy of wind vibration or earthquake, thereby improving the anti-seismic ability of the structure.
