Problems solved by technology

[0003] (1) Ordinary plate-type rubber bearings are widely used in road and bridge construction because of their simple structure, convenient installation, and low price, but their horizontal stiffness and horizontal displacement are small, and they cannot be used in areas with a fortification intensity of 7 degrees;
[0004] (2) The horizontal rigidity and horizontal displacement of the lead core and high damping shock-isolation rubber bearing are relatively large, but compared with the lead core and high-damping shock-isolation rubber bearing of ordinary plate bearings, the cost is high, and the production and installation are more complicated The problem

Embodiment 1

[0039] An energy-saving and convenient shock-isolation bearing, which includes a bearing core formed by vulcanization and pressing of multi-layer rubber sheets and thin steel plates. The plate 2 and the outer structural plate 1, the inner structural plate is connected with the support core, and the outer structural plate is installed on the outer side of the inner structural plate;

[0040] The outer surface of the inner structural plate 2 has a plurality of structural protrusions I21, and the inner surface of the outer structural plate 1 has structural grooves 11 corresponding to the structural protrusions I, that is, the outer structural plate and the inner structural plate are assembled together. , the structural bump I21 falls into the structural groove 11, and there is a gap between the structural bump I21 and the structural groove;

[0041] The structural bumps I21 are evenly distributed, and they are arranged in circles, triangles, rectangles or polygons, or orthogonal ...

Embodiment 2

[0046] An energy-saving and convenient seismic isolation support, its structure is basically the same as that of Embodiment 1, the difference is that: the lower end of the support core is provided with a limit combination device, and the upper end of the support core is provided with a structure and a support The same limiting combination device at the lower end of the core. (see attached figure 2 )

Embodiment 3

[0048]An energy-saving and convenient seismic isolation support, its structure is basically the same as that of Embodiment 1, the difference is that: the lower end of the support core is provided with a limit combination device, and the upper end of the support core is provided with a sliding structure device, and the sliding structure device includes a sliding plate 5, a stainless steel plate 6 and an outer connecting steel plate 7 sequentially connected to the upper end of the support core. (see attached Figure 5 )

Abstract

The invention discloses an energy-saving and convenient type shock insulation supporting seat, including a supporting seat core. An anti-slip combination device is arranged at the lower end of the supporting seat core. The anti-slip combination device includes an inner construction plate and an outer construction plate. The inner construction plate is connected with the supporting seat core. The outer construction plate is mountedon the outer side face of the inner construction plate in a matched mode. A plurality of construction lugs are arranged on the outer side face of the inner construction plate. The inner side face of the outer construction plate is provided with a construction groove which is matched correspondingly with the construction lugs. An interspace is left between the construction lugs and the construction groove. According to the energy-saving and convenient type shock insulation supporting seat, the structure is simple, processing and manufacturing are easy, corresponding installation of the supporting seat is convenient and quick, the speed is high, the supporting seat is easy to change and maintain, vertical stiffness is sufficient to withstand the vertical load, and the seismic response of the structurecan be reduced; and phenomena ofslippage, separation,fall and the like caused by excessive large displacement of the supporting seat due tolarge horizontalshear deformation of the bridge superstructurecan be avoided, so that the safety and durability of the bridge structureareimproved to ensure the use safety of the construction of the overall highway bridge structure.

Description

technical field [0001] The invention relates to an anti-vibration and isolation support for bridges, in particular to an energy-saving and convenient anti-vibration support. Background technique [0002] The bridge bearing is an important and key component installed between the bridge superstructure and the abutment. At present, the commonly used bearings include lead core isolation rubber bearings, high damping isolation rubber bearings and ordinary plate rubber bearings, etc.; The problem is: [0003] (1) Ordinary plate-type rubber bearings are widely used in road and bridge construction because of their simple structure, convenient installation, and low price, but their horizontal stiffness and horizontal displacement are small, and they cannot be used in areas with a fortification intensity of 7 degrees; [0004] (2) The horizontal rigidity and horizontal displacement of the lead core and high damping shock-isolation rubber bearing are relatively large, but compared wit...
