Assembling type enhanced steel-wood buckling constraint support with tapping screws

Abstract

The invention discloses an assembling type enhanced steel-wood buckling constraint support with tapping screws. The support comprises a core material, a restraining tube and a non-sticking material or an air layer, wherein the non-sticking material or the air layer is arranged between the core material and the restraining tube, the core material comprises connecting segments, transition segments, a core working segment, a limit clamp and stiffening plates, the two ends of the core working segment are connected with the connecting segments through the transition segments, the limiting clamp is arranged in the middle of the core working segment, the transition segments are in an arc shape, connecting bolt holes are formed in the connecting segments, each stiffening plate is perpendicularly arranged between each connecting segment and the corresponding transition segment in the vertical direction, the restraining tube comprises a piece of upper core material laminated wood and a piece of lower core material laminated wood, the wood texture direction of the upper core material laminated wood and the lower core material laminated wood is transverse, and the tapping screws are perpendicularly nailed into the position between the upper core material laminated wood and the lower core material laminated wood. The assembling type enhanced steel-wood buckling constraint support is used in the earthquake region, post-earthquake rehabilitation can be facilitated, and the earthquake damage can be reduced. The assembling type enhanced steel-wood buckling constraint support has the wide application prospect in the moderate and high-rise wood structural buildings.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a buckling constrained support for reducing the impact of earthquake disasters on engineering structures. Background technique [0002] In the field of middle and high-rise wooden structure building design, there is a big gap between my country and developed countries such as Europe and the United States. Therefore, it is necessary to carry out relevant research in the field of mid-rise timber structure design. The frame-bracing structure system of timber structures is one of the lateral force-resisting systems of mid-rise timber structures, and the development of new energy-dissipating braces is a key technical issue in the practical application of the above problems. Research on new energy-dissipating supports can promote the application of modern wood structures in mid- and high-rise building construction, and ensure their safety and stability during use. [0003] At present, m...

Problems solved by technology

[0003] At present, most of the buckling-restrained braces commonly used in engineering in my country are composed of peripheral filled concrete steel pipe restraint components and core components under axial force. This kind of buckling-restrained brace is not only self-heavy, but also takes a long time for concrete pouring and curing, which will seriously affect buckling Production efficiency of constrained supports
