Self-resetting glued wood structure beam-column joint capable of replacing top-bottom friction energy-consuming device

Abstract

The invention discloses a self-resetting glued wood structure beam-column joint capable of replacing top-bottom friction energy-consuming device. The self-resetting glued wood structure beam-column joint comprises a glued wood column, a glued wood beam located on one side of the glued wood column, and two friction energy-consuming devices connecting the glued wood column and the glued wood beam into one body, the two friction energy-consuming devices are respectively arranged on the upper part and the lower part of the glued wood beam, each friction energy-consuming device comprises two internal friction steel plates which are fixed on the glued wood beam are provided with a first friction bolt hole and a first fixing bolt hole, an inner friction end plate connecting the two inner frictionsteel plates into an integral , two outer friction steel plates which are fixed on the gluing wood column are provided with a third friction bolt hole and a third fixing bolt hole, and an external friction connecting steel plate connecting the two outer friction steel plates. The self-resetting glued wood structure beam-column joint can consume the energy under the earthquake action, eliminate orreduce the residual deformation of the assembled wooden structure under the earthquake action.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a self-resetting wooden structure beam-column joint that can replace top and bottom friction energy consumers. Background technique [0002] In order to improve structural construction efficiency and building quality, the state has promulgated a series of documents to vigorously promote the industrialization of construction. The document clearly pointed out that the development of prefabricated buildings is a major change in the construction method and an important measure to promote the structural reform of the supply side and the development of new urbanization. On the other hand, as a building form with a long history and advancing with the times, the wooden structure system has the advantages of flexible design, simple construction, fast construction, good wind and earthquake resistance, high comfort, beautiful structure, energy saving and environmental protection, etc. It can ...

Problems solved by technology

[0004] (1) The connection of prefabricated structural nodes has always been one of the hot issues discussed in the academic and engineering circles, and the application of prefabricated building structures is also limited to a certain extent, and the failure mode of prefabricated wooden structure nodes under earthquake action shows even more Large unpredictability. At the same time, the elastic modulus of wood is relatively low, resulting in large deformation. After the wood structure enters plasticity, the deformation is difficult to recover, and it is easy to form a large residual deformation

[0005] (2) The beam-column connection is the most critical design link in the frame design of the assembled structure. The existing connection forms mostly refer to the node structure of the steel frame, but the wood structure itself does not have the advantages of high strength of the steel structure, and the wood frame beams are commonly used The rigidity of the column joints is small, and it is designed according to the hinged joints in the structural design. The insufficient joint stiffness is a restrictive factor for the wooden frame joints. Setting a large number of supports will have a certain degree of influence on the aesthetics of the structure, which in turn will make the building's performance insufficient. to play
