Self-tie steel-wood combined joint and mounting method

Abstract

The invention relates to the field of building structures, and discloses a self-tie steel-wood combined joint and a mounting method. The self-tie steel-wood combined joint comprises a self-tie combined column, combined beams and beam column reinforcing kits. The self-tying combined column comprises a central column body and peripheral tie columns located on the outer side of the central column body, and the central column body and the peripheral tie columns are in mortise and tenon connection to form a square column body. Flange plates of the combined beams are in mortise and tenon connection with webs; The flange plates are in mortise and tenon connection with the peripheral tie columns. Each beam column reinforcing kit comprises two column outer ring plates, and the column outer ring plates are arranged on the self-tie combination column in a sleeving mode and connected with the flange plates through bolts. According to the self-tie combined column, every two surrounding tie columns are tied, the central tie column and the surrounding tie columns are tied mutually, and the integrity and the energy dissipation capacity of members are improved; The energy consumption form of the self-tie combined column is mainly mutual staggered friction of different parts of the self-tie combined column in the vertical direction, and the phenomenon that a single member is damaged can be avoided.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a self-tensioning steel-wood composite node and an installation method. Background technique [0002] Timber structure buildings use wood as the force-bearing member, which has better tensile capacity than concrete materials, is not easy to be brittle, and does not require curing time. As the main material of construction, wood is environmentally friendly, and compared with reinforced concrete buildings and steel structure buildings, it reduces a large amount of carbon emissions. At the same time, the connection characteristics and material characteristics of wooden structure buildings determine its faster construction speed. [0003] However, the connection nodes of existing wooden structures have many components and complex connections, and the cross-section of the column is usually pierced due to the need for connection, which is likely to cause stress concentration; Dissi...

Problems solved by technology

[0003] However, the connection nodes of existing wooden structures have many components and complex connections, and the cross-section of the column is usually pierced due to the need for connection, which is likely to cause stress concentration; Dissipation of earthquake energy leads to problems such as single material used, small parts are easy to break, no recovery ability, and the mechanical properties of wood cannot be maximized in earthquakes.
