[0033] The wooden energy-dissipating and shock-absorbing device includes two connecting sections, and the two connecting sections are connected by an energy-dissipating section;
[0034] The energy-dissipating section includes two sections of wooden connectors, which are connected by mild steel shear dampers. The outer ends of the two wooden connectors are respectively provided with dovetail tenons. The connecting sections are respectively provided with dovetail-shaped grooves, and the tenons of the two wooden connecting parts are respectively inserted into the grooves of the two connecting sections.
[0035] The wood connector and the mild steel shear damper are connected by bolts, and a positioning flute-groove is provided between the wood connector and the mild steel shear damper.
[0036] The connecting section is...
Embodiment 1
[0044] Example 1, such as Figure 1 to Figure 5 As shown, the connecting section of this embodiment is a wooden post.
[0045] Wherein, the friction plate 131 is an optional component. The friction plate 131 is connected to the wooden connector 132 through chemical glue or wooden connectors.
Embodiment 2
[0046] Example 2, such as Figure 6 ~ Figure 10 As shown, the connection section of this embodiment is a wooden wall.
[0047] The displacement-load theoretical curve of the friction type wooden energy dissipation shock absorber is as follows: Figure 11 It can be seen that under the action of reciprocating load, the curve is full, indicating that the device has strong energy dissipation performance.

Abstract
The invention discloses a wooden energy dissipation and shock absorption device and a wooden structure system with the same. The wooden energy dissipation and shock absorption device comprises two connecting sections, wherein the two connecting sections are connected through an energy dissipation section. The energy dissipation section comprises two sections of wooden connecting pieces, wherein the two sections of the wooden connecting pieces are connected through soft steel shear dampers, dovetail-shaped tenons are separately arranged at the outer ends of the two wooden connecting pieces, dovetail-shaped grooves are separately formed in the two connecting sections, and the tenons of the two wooden connecting pieces are separately inserted into the grooves of the two connecting sections. The connecting sections are wooden columns or wooden panel walls. When the connecting sections are the wooden columns, friction plates are separately arranged at the outer ends of the two wooden connecting pieces. A main structure of the wooden structure system is rigidly connected with the wooden energy dissipation and shock absorption device. According to the wooden energy dissipation and shock absorption device, earthquake energy can be dissipated, the damage to wooden structure buildings under an earthquake is reduced, and energy dissipation components after the earthquake are convenient toreplace. The wooden energy dissipation and shock absorption device and the wooden structure system with the same can be used for improving the seismic performance of existing wooden structure buildings and building new wooden structure buildings.
Description
technical field [0001] The invention relates to a wooden structure system, in particular to a wooden energy-dissipating and shock-absorbing device and a wooden structure system with the same. Background technique [0002] Timber structure is the structural form adopted by a large number of existing historical relic buildings and new buildings. However, earthquake damage records show that some existing wooden structures have poor seismic performance, and will cause greater damage or even collapse during an earthquake, resulting in huge economic losses and immeasurable cultural losses. At the same time, the seismic performance of newly built wooden structures needs to be further improved. Therefore, the improvement and enhancement of the seismic performance of wooden structures has become one of the important issues to be solved urgently. [0003] At present, for the seismic performance reinforcement of existing wooden structures, reinforcement methods based on component lev...
