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 can only be used in simply supported or hinged situations; if the number

Abstract

The invention discloses a fabricated wood structure embedded steel bar joint which comprises a wood beam, a wood column, a beam-end embedded steel bar, a joint connector and a joint fastener. The wood beam and the wood column are connected through the joint connector, the beam-end embedded steel bar and the joint fastener, the beam-end embedded steel bar is embedded into a duct pre-bored or reserved in a beam end or a channel formed in the beam end through structural adhesives, the channel is sealed by a small batten and structural adhesives, the joint connector is fixed onto a column body through the joint fastener, the joint fastener is fixed to one side of the wood column back to the wood beam through an anchor plate and a cushion block, and cross grains of the embedded steel bar of the beam end are enhanced by self-tapping screws. The invention further discloses a construction method of the fabricated wood structure embedded steel bar joint. Structural stability can be ensured under small earthquake, large deformation of a structure can be realized under large earthquake, structural damage can be controlled, and the fabricated wood structure embedded steel bar joint is high in bearing capacity, energy dissipation and ductility.

Description

technical field [0001] The invention belongs to the field of civil engineering, relates to a wood structure node, in particular to an assembled wood structure planting reinforcement node and a construction method thereof. 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 structure. Different from the traditional forms of...
