Problems solved by technology

[0005] 1) Not easy to replace and overhaul
For iron reinforced components, it is difficult to replace them due to corrosion problems, and at the same time brings potential safety hazards; for FRP reinforcement methods, since FRP is pasted on the surface of wooden components with structural adhesive, it is difficult to replace, and it is not easy to repair the reinforced parts. overhaul
[0006] 2) The problem of difficult reset after the earthquake still exists
Traditional reinforcement methods can generally improve the stiffness of mortise and tenon joints, and at the same time have a certain energy dissipation capacity, but after the earthquake, there are still residual deformations, and it is still difficult to restore the position, and the repair cost is also high
[0007] 3) After reinforcement, it will generally affect the internal appearance of the building
After the traditional method of reinforcement, the general reinforcement materials are exposed at the joints, which will have a certain impact on the appearance of the original building, which does not conform to the principle of repairing the old as the old

Embodiment 1

[0035] Such as Figure 1-7 As shown, a reinforcement and energy dissipation device for mortise joints of a wooden structure includes a wooden beam 1, a wooden column 2, a mortise joint 3, a reinforcement 4, a joint connector 5 and a joint fastener 6. The wooden beam 1 and the wooden column 2 are connected by the tenon-and-mortise joint 3, the upper and lower surfaces or both sides of the beam end of the wooden beam 1 are provided with channels 9, and the planting bars 4 are pre-planted in the channel 9 and pass through the small wood The strip 10 is closed with a special structural glue. One end of the node connector 5 is connected to the planting bar 4, and the other end is connected to the node fastener 6. The node fastener 6 penetrates the shaft of the wooden column 2 and passes through the anchor plate 7. And the block 8 are fixed on the side of the wooden column 2 facing away from the wooden beam 1.

[0036] Such as Figure 8-10 As shown, the node connector 5 is one of stee...

Embodiment 2

[0039] Such as Picture 11 As shown, there is a device for strengthening and energy-consuming damping of wooden structure tenon-and-mortise joints. The rest of the structure is the same as that of Embodiment 1, except that the cross section of the wooden column 2 is square.

Embodiment 3

[0041] Such as Picture 12 with 13 As shown, a device for reinforcing and energy-consuming damping of a tenon-and-mortise joint of a wooden structure, the rest of the structure is the same as that of Embodiment 1, except that the tenon-and-mortise joint 3 is a through tenon.

Abstract

The invention discloses a device for reinforcement, energy dissipation and seismic mitigation of a tenon and mortise joint of a timber structure. The device for reinforcement, energy dissipation and seismic mitigation of the tenon and mortise joint of the timber structure comprises a wood beam, a wood pole, the tenon and mortise joint, embedded steel bars, joint connecting pieces and joint fastening pieces, wherein the wood beam is connected with the wood pole through the tenon and mortise joint, conduits are formed in the upper end surface and the lower end surface of the wood beam or in the two lateral surfaces of the wood beam respectively, the embedded steel bars are embedded in the conduits in advance, the conduits are sealed through small battens and special structural adhesive, one end of each joint connecting piece is connected with a corresponding embedded steel bar, the other end of each joint connecting piece is connected with a corresponding joint fastening piece, and the joint fastening pieces penetrate through the pole body of the wood pole and are fixed on the side, back on to the wood beam, of the wood pole through anchor plates and cushion blocks. The device for reinforcement, energy dissipation and seismic mitigation of the tenon and mortise joint of the timber structure is high in bending resistance, energy-dissipation capacity and ductility, and capable of guaranteeing stability of the structure under the small earthquake condition, achieving serious deformation under the large earthquake condition to control structural damage, and achieving automatic restoration of the structure after an earthquake.

Description

Technical field [0001] The invention belongs to the field of civil engineering and relates to a tenon-and-mortise joint, in particular to a beam-column tenon-and-mortise joint of an ancient building wooden structure, which is mainly (but not exclusively) used for the reinforcement, energy dissipation and shock absorption of the existing wooden structure beam-column tenon joint It can also be used to strengthen and reduce energy consumption and vibration of newly-built wooden beam-column joints. Background technique [0002] my country's wooden architecture has a long history. From ancient palaces, temples and halls to residential buildings, a large number of ancient architectural wooden structures are used. At the same time, ancient architectural wooden structures are widely distributed, almost all over the country. The famous ancient wooden structures that have been passed down to this day are: Forbidden City in Beijing, Muta in Yingxian County in Shanxi, Dule Temple in Jixian Co...
