Abstract
The utility model discloses a stiffness variable shock-reducing and isolating type rubber support capable of preventing cutting and torsion. The rubber support is characterized by consisting of an upper support plate, a rubber plate and a lower support plate, wherein the rubber plate is arranged between the upper support plate and the lower support plate, an upper limit plate is fixed around the upper support plate, a lower limit plate is arranged around the lower support plate, the rubber plate is internally provided with an alloy steel plate, and a plurality of holes are arranged on the alloy steel plate. The rubber support has the advantages that materials are saved, the structure and the process are simple, the processing cost is low, the fixed effect is good, and requirements on stiffness of bridges can be met, etc, therefore, the operability is strong, and the rubber support is suitable for wide promotion and use.
Description
Technical field
The utility model relates to bridge pad, specifically is that a kind of anti-shearing, torsion proof becomes rigidity and subtracts the shock insulation laminated rubber bearing.
Background technology
Along with the further quickening of overhead high-speed railway and other infrastructure construction, the also increase greatly of consumption as the laminated rubber bearing of tie-beam body and bridge pier subtracts the shock insulation purpose in order to reach; The top board and the base plate of the laminated rubber bearing that uses at present are the basin type; Top board and base plate can move certain distance relative to propping up seat body, add man-hour, get a thicker metal sheet; The inboard is milled out a circle or square groove, form the limiting block limit at periphery like this.The top board of said structure and base plate are not only wasted steel, and manufacturing procedure is complicated, and cost of production increases greatly.And its rigidity do not reach some special rigidity requirement yet, and the shear resistant and the antitorque commentaries on classics property of existing bearing are also very poor simultaneously, therefore need make improvements.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, subtracts good, anti-shearing, the antitorque commentaries on classics of isolation property, practices thrift steel, anti-shearing, torsion proof easy to process, that cost is low become rigidity and subtract the shock insulation laminated rubber bearing.
The technical scheme that the utility model is adopted in order to achieve the above object is: a kind of anti-shearing, torsion proof becomes rigidity and subtracts the shock insulation laminated rubber bearing, it is characterized in that by upper bracket plate, rubber tile; Lower support plate is formed; Said rubber tile is arranged between upper bracket plate and the lower support plate, and said upper bracket plate periphery is fixed with the upper limit plate, and the lower support plate periphery is fixed with lower limiting board; Be provided with alloy-steel plate in the said rubber tile, this alloy-steel plate is provided with some holes.
Become rigidity according to described anti-shearing, the torsion proof of the utility model and subtract the shock insulation laminated rubber bearing, it is characterized in that said upper limit plate through screw on the upper bracket plate.
Become rigidity according to described anti-shearing, the torsion proof of the utility model and subtract the shock insulation laminated rubber bearing, it is characterized in that said lower limiting board through screw on lower support plate.
Become rigidity according to described anti-shearing, the torsion proof of the utility model and subtract the shock insulation laminated rubber bearing, it is characterized in that said alloy-steel plate is more than one and is arranged in the rubber tile evenly and at intervals.
Become rigidity according to described anti-shearing, the torsion proof of the utility model and subtract the shock insulation laminated rubber bearing, it is characterized in that the hole on the said two adjacent alloy-steel plates is dislocatedly distributed.
The utility model is provided with some holes on alloy-steel plate, simultaneously the hole on the two adjacent alloy-steel plates is dislocatedly distributed, so contacts close and firm more between rubber tile and the alloy-steel plate; Thereby improved the shear resistant and the antitorque commentaries on classics property of this bearing greatly, it also has economical with materials simultaneously, and simple in structure; Operation is simple, and processing cost is low, good fixing effect; Can arrive the advantages such as rigidity requirement of bridge, so strong operability, be fit to promote the use of widely.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-upper bracket plate, 2-upper limit plate, 3-rubber tile, 4-alloy-steel plate, 5-lower support plate, 6-lower limiting board, 7-hole.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing the utility model:
As shown in Figure 1: a kind of anti-shearing, torsion proof becomes rigidity and subtracts the shock insulation laminated rubber bearing by upper bracket plate 1; Rubber tile 3; Lower support plate 5 is formed. and said rubber tile 3 is arranged between upper bracket plate 1 and the lower support plate 5; Said upper bracket plate 1 periphery is fixed with upper limit plate 2, this upper limit plate 2 through screw on upper bracket plate 1.Lower support plate 5 peripheries are fixed with lower limiting board 6, this lower limiting board 6 also through screw on lower support plate 5.Be provided with alloy-steel plate 4 in the said rubber tile 3, this alloy-steel plate 4 is more than one and is arranged on equably in the rubber tile 3.And this alloy-steel plate 4 is provided with some holes 7, and the hole 7 on the per two adjacent alloy-steel plates all is dislocatedly distributed, and makes the close and firm more that contacts of rubber tile 3 and alloy-steel plate 4 like this, thereby has strengthened its anti-shearing and antitorque commentaries on classics property.
