Description

Technical Field

[0001] The utility model relates to the technical field of building shock absorption, in particular to a horizontal limit and energy dissipation device for a shock-isolating building. Background Art

[0002] In the prior art, for example, a three-dimensional seismic isolation bearing with the announcement number CN 113404166B disclosed on the Chinese patent website can only achieve compression and shock absorption in the vertical direction, and the heat generated by the friction of the conical surfaces of the spring group composed of the inner ring and the outer ring during long-term compression and shock absorption will extend to the center of the cross-section of the inner ring and the outer ring, making it difficult to dissipate the internal heat. The heat generated by long-term friction will directly cause the material of the spring group to be "heated", so that the material cannot meet the preset shock absorption mechanical properties. Utility Model Content

[0003] Based on the existing technical problems, the utility model proposes a horizontal limiting and energy dissipation device for a seismic isolation building.

[0004] The utility model provides a horizontal limit and energy dissipation device for a seismic isolation building, comprising a cylinder, wherein the inner wall of the cylinder is respectively provided with a guide sleeve, a spring group, a tension and compression rod and a top plate from left to right.

[0005] The outer surface of the guide sleeve is slidably connected to the inner wall of the cylinder, the inner wall of the spring group is movably connected to the outer surface of the guide sleeve, the outer surface of the tension and compression rod is connected to the inner wall of the guide sleeve and extends to the outside of the cylinder, and the outer surface of the top plate is slidably connected to the inner wall of the cylinder and is elastically supported by the spring group.

[0006] The spring assembly is formed by an inner spring and an outer spring being pressed against each other in the form of a β° cone.

[0007] Preferably, a pulling and pressing flat pad is fixedly sleeved on the outer end surface of the pulling and pressing rod, and when the pulling and pressing flat pad is driven by the pulling and pressing rod to retract and squeeze, it passes through the cylinder and then squeezes the spring group through the top plate.

[0008] Through the above technical solution, the tension and compression flat pad can achieve position limiting during compression and shock absorption and facilitate stable force bearing.

[0009] Preferably, the interior of the tension and compression flat pad is hollow, and a connecting rod is fixedly installed inside the hollow tension and compression flat pad along the axial direction of the tension and compression rod;

[0010] A weight-reducing hole is provided at the axis of the tension and compression rod.

[0011] Through the above technical solution, the hollow tension and compression pads and weight-reducing holes are provided to reduce the weight of the large shock-absorbing support, thereby preventing the tension and compression rods from bending and deforming due to excessive force when placed horizontally for use.

[0012] Preferably, anti-stress grooves are opened inside the inner spring and the outer spring along their circumferential direction, and the internal annular array of the anti-stress grooves is provided with extrusion balls. The extrusion balls in the outer spring are made of cemented carbide, and the extrusion balls in the inner spring are made of cemented carbide or lead balls.

[0013] Through the above technical solution, the anti-stress groove can not only prevent the problem of stress concentration and deformation of the spring group when it is subjected to force, but also guide the heat generated by the friction surface of the spring group out from the notch of the anti-stress groove.

[0014] Preferably, the inner diameter of the inner spring is D1, the outer diameter of the outer spring is D2, the gaps between adjacent outer springs and inner springs are both δ, the free height of the spring group is H0, and the depth of a single inner spring is h.

[0015] Through the above technical solution, the parameters related to the inner spring and the outer spring can be systematized, which is convenient for later production and improvement to provide basic parameters, so that the spring group 3 can obtain the best shock absorption effect.

[0016] Preferably, the value range of β is 12° to 20°.

[0017] The above technical solution makes it easy to obtain the best friction bearing surface.

[0018] Preferably, the wear-resistant layer is made of any one of tungsten, titanium alloy, molybdenum disulfide or cemented carbide material.

[0019] Through the above technical solution, the wear-resistant layer can allow the surface of the cone to be coated with a layer of high-temperature resistant and wear-resistant material to prevent the spring group from being hot-melt-bonded due to excessive friction frequency.

[0020] The beneficial effects of the present invention are:

[0021] 1. By arranging the inner wall of the cylinder to be respectively provided with a guide sleeve, a spring group, a tension and compression rod and a top plate from left to right, the support can have a vibration-absorbing action in both the telescopic and extension directions.

[0022] 2. By coating the conical surface of the spring group with a wear-resistant layer, the wear resistance of the spring group can be increased and the shock absorption performance of the support can be increased. BRIEF DESCRIPTION OF THE DRAWINGS
