Assembled semi-rigid wood structure joint

Abstract

The invention discloses an assembled semi-rigid wood structure joint. The assembled semi-rigid wood structure joint comprises a component I, a component II, a bending connecting piece, a shear connecting piece, an assembling piece, a steel cushion plate and connecting bolts, wherein the component I is a wood component, the bending connecting piece and the shear connecting piece are fixedly arranged at the end portion of the component I by adopting a steel plate implanting manner, the bending connecting piece and the shear connecting piece are T-shaped steel, the surfaces of the parts thereof implanted into the wood member are vulcanized with rubber layers, the end portion of the component I is pre-grooved at a steel plate implanting position, and the bending connecting piece and the shear connecting piece are connected through the connecting bolts and the assembling piece; the end portion of the component I can be connected with the side surfaces and the end portion of the component II or can be connected with a concrete foundation. The joint disclosed by the invention has higher bending capacity, joint rigidity, energy dissipation capacity and ductility performance. The joint not only can guarantee the structure stability under small earthquakes, but also can realize the prevention of large deformation of the structure under large earthquakes and control structure damages, and realizes ideal effects of high bearing capacity, high energy dissipation capacity and high ductility.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a wood structure node, in particular to a semi-rigid wood structure node suitable for large-scale wood structures that can be quickly assembled. Background technique [0002] Energy conservation and emission reduction, and the development of green buildings are one of the social tasks that our country urgently needs to vigorously promote. The development of wooden structures meets the needs of "energy saving and resource saving" in buildings. It is of great environmental protection significance and conforms to the basic national policy of energy saving and emission reduction and the establishment of a conservation-oriented society. [0003] Similar to steel structures, modern long-span timber structure joints are the key links of the entire structural system, and play an important role in the bearing capacity, stiffness, and ductility of the entire structur...

Problems solved by technology

Taking the commonly used pin-bolt connection as an example, usually the pin-bolt connection is mainly borne by the bending bearing of fasteners such as pins and the pressure bearing of wood pin grooves. If the number of fasteners is small, the flexural bearing capacity and rotational The rigidity is limited, and it can only be used in simply supported or hinged situations; if the number of fasteners is large, it is easy to cause the joi
