Embodiment 1

[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention includes: connector I3, connector II4, steel bracket 5, connector III6, stiffener 51, rectangular steel pipe 7, viscous friction damper 8, metal energy dissipation rod 9, etc.

[0029] The connecting piece II4 is a rectangular frame with an upper opening, and the connecting piece I3 is a rectangular frame with a lower opening. Both openings have ear plates, and bolt holes are reserved on the ear plates. The connecting piece II4 passes through the rectangular frame located on the lower side of the wooden beam. The steel pipe 7 is connected with the connector I3 by the bolt I10 to form a closed rectangular frame, the inner cross-sectional size of the closed rectangular frame is consistent with the cross-sectional size of the wooden beam 1, and the wooden beam 1 is located in the closed rectangular frame to realize fixing. Wherein the rectangular steel pipe 7 reserves a certain gap betwe...

Embodiment 2

[0033] Such as figure 1 , figure 2 , image 3 , Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the energy-dissipating and shock-absorbing devices of the present invention are installed on the upper and lower sides of the wooden beam; the connection method between the device and the structure is the same as that of Embodiment 1.

Embodiment 3

[0035] As preferred in embodiment 1, in the steel support 5, also comprise vertical steel plate, horizontal steel plate is connected on the outer surface of arc-shaped steel plate to be right angle shape, and the lower corner of horizontal steel plate is welded with stiffener 51, stiffener 51 and vertical There is a gap between the outer sides of the vertical steel plate and a part of the inner side of the connector III6, which is consistent with the size of the connector III6, and the connector III6 passes through the gap. combine.

[0036] When the connector III6 is circular, the vertical steel plate is an arc-shaped steel plate, and the surface attached to the wooden column 2 is arc-shaped with the same radius as the wooden column 2 .

[0037] When the present invention is applied in practice, the damping size of the nodes can be controlled by adjusting the thickness of the viscous friction damper 8, and different pretightening forces can be applied by adjusting the tightne...

Abstract

An energy-dissipating damping device suitable for the mortise-tenon joints of the timber structures of ancient buildings comprises connecting parts II and a connecting part III, wherein the upper endsof the connecting parts II are connected with connecting parts I through bolts I to form closed structures fixed around a wooden beam; two ends of the connecting part III are connected through a boltII to form a closed structure fixed around a wooden pillar; the connecting part III is mounted on a steel support frame with a horizontal steel plate; the lower ends of the connecting parts II are connected to the upper surface of a rectangular steel tube; a viscous friction damper is arranged between the upper surface of the steel support frame and the lower surface of the rectangular steel tube; and metal energy-dissipating rods run from the lower surface of the rectangular steel tube to the horizontal steel plate of the steel support frame through the viscous friction damper. Under the action of earthquake, relative sliding occurs between all layers of the viscous friction damper to drive the metal energy-dissipating rods to bend to dissipate energy together. The energy-dissipating damping device has the advantages of strong energy-dissipating capacity and resistant-lateral rigidity, simple structure, convenient mounting, easy replacement and so on.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of wooden structures of ancient buildings, and in particular relates to an energy-dissipating and shock-absorbing device suitable for mortise and tenon joints of wooden structures of ancient buildings. Background technique [0002] Mortise and tenon joints of wooden structures in ancient buildings have typical semi-rigid characteristics. Beams and columns can produce a certain amount of relative rotation at the tenon and tenon joints, and at the same time can bear the bending moment generated by the upper load at both ends. Because of this, tenon and tenon joints have become The position most likely to be damaged in the wooden structure of ancient buildings has been proved to be correct through the damage detection of existing wooden structures of ancient buildings and the analysis of previous test results. Therefore, the reinforcement and repair of mortise and tenon joints in wooden structur...
