Embodiment 1

[0031] Such as figure 1 and 8 As shown, a prefabricated wood structure beam-column planting reinforcement node, including wooden beam 1, wooden column 2, planting reinforcement 3, adhesive 4, assembled connector 5, node fastener 7 and steel backing plate 6, said The wooden beam 1 and the wooden column 2 are connected by an assembled connector 5, a planting bar 3 and a node fastener 7, and the planting bar 3 is planted in the pre-drilled or reserved channel at the end of the beam through an adhesive 4 or In the opened channel, the assembled connector 5 is fixed on the column body through the node fastener 7, and the node fastener 7 is fixed on the side of the wooden column 2 facing away from the wooden beam 1 through the steel backing plate 6, and the beam end is on the The 3 parts of the planting bars are reinforced with self-tapping screws 8 for transverse grains.

[0032] The cross-sectional shape of the wooden beam 1 and the wooden column 2 is square, rectangular or circu...

Embodiment 2

[0036] Such as figure 2 and 9 As shown, the joint structure of the prefabricated wood beam-column planting bar in this embodiment is the same as that in Embodiment 1, the difference is that the prefabricated connectors described in this embodiment are as follows Figure 6 shown.

Embodiment 3

[0038] Such as image 3 and 10 As shown, the joint structure of the prefabricated wood beam-column planting bar in this embodiment is the same as that in Embodiment 1, the difference is that the prefabricated connectors described in this embodiment are as follows Figure 7 shown.

Abstract

The invention discloses an assembly wood structure beam column embedded steel bar joint which comprises a wood beam, a wood column, an embedded steel bar, adhesives, an assembly connector, a joint fastener and a steel base plate. The wood beam is connected with the wood column through the assembly connector, the embedded steel bar and the joint fastener, the embedded steel bar is embedded into a pre-bored or reserved duct or formed channel at a beam end, the assembly connector is fixed to a column body through the joint fastener, the joint fastener is fixed on one side of the wood column back to the wood beam through the steel base plate, and cross grains of the embedded steel bar position at the beam end are strengthened by the aid of self-tapping screws. The joint has high bending resistance, joint stiffness, energy-dissipating capacity and ductility, can ensure a reliable structure under a small earthquake and can also control structural damage when the structure greatly deforms under a large earthquake, and ideal effects of high bearing capacity, high energy dissipation and high ductility are achieved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a wood structure node, in particular to an assembled wood structure beam-column bar planting node. 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 mortise and tenon joints an...
