Problems solved by technology

Although the isolation (vibration) effect is remarkable, the horizontal direction of the support is relatively soft, and a certain displacement may occur under the action of small earthquakes and moderate earthquakes, that is, the seismic response of the isolation support cannot be controlled in stages
Therefore, the existing seismic isolation rubber bearings have certain limitations in the application of some special buildings with strict displacement requirements.

Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 to Figure 18 As shown, a tension locking device used on a vibration-isolating rubber bearing includes: mounting steel plates 1a, 1b, external sleeves 2a, 2b, large nuts 3a, 3b, threaded screws 4a, 4b, splicing nuts 5a , 5b, tie rod 6.

[0037] like figure 1 , Image 6 The common lead-core rubber support 7 is composed of a connecting plate 8 , a sealing plate 9 , a steel plate 10 , a rubber layer 11 , and a lead core 12 .

[0038] like Figures 14 to 16 As shown, the external sleeve 2 contains threads that can be matched with the threaded screw 4 . like Image 6 , Figure 7 As shown, the lengths of the outer sleeves 2a, 2b are greater than or equal to twice the overhanging lengths of the threaded screws 4a, 4b.

[0039] like figure 1 , figure 2 and Figure 7 As shown, the threaded screws 4a, 4b respectively pass...

Abstract

The invention relates to a pulled locking device for an earthquake isolation rubber bearing. The pulled locking device comprises two installation steel plates (1), fastening pieces, splicing nuts (5) and a pull rod (6). The two installation plates (1) are placed at the upper portion and the lower portion of the rubber bearing respectively and connected with the rubber bearing through bolts. Vertically-corresponding reserved holes are formed in corners of the installation steel plates (1). The fastening pieces are fixed to the upper and lower installation steel plates (1) through the reserved holes. The fastening pieces are connected with the pull rod (6) through the splicing nuts (5). When affected by small-earthquake loads, the whole pulled locking device does not displace under the action of the pull rod (6), a small angle is generated at the top end of the pull rod (6), and the pull rod (6) is pulled; when affected by loads of large-earthquake or loads of larger-earthquake, the pull rod (6) is pulled off, the rubber bearing plays a role in energy dissipation, the bearing displaces horizontally, and secondary control is achieved.

Description

technical field [0001] The invention relates to a tension locking device used on a vibration isolating rubber bearing. Background technique [0002] Under the action of earthquake or other loads, in order to consume energy and reduce damage to the superstructure, the existing vibration isolation rubber bearings often generate large displacements in the horizontal direction. Although the seismic isolation (vibration) effect is remarkable, the bearing is relatively soft in the horizontal direction, and may also have a certain displacement under the action of small earthquakes and moderate earthquakes, that is, the seismic response of the isolation bearing cannot be controlled in stages. Therefore, the existing vibration isolation rubber bearings have certain limitations in the application of some special buildings with strict displacement requirements. SUMMARY OF THE INVENTION [0003] In view of the defects existing in the prior art, the purpose of the present invention is...
