Description
Technical field
The utility model belongs to civil engineering, earthquake engineering technical field, is specifically related to a kind of neoprene bearing: be particularly related to a kind of fine and closely woven high-strength steel mesh laminated rubber bases of putting more energy into.
Background technology
China is the new highway bridge of building at present, except having individually the bridge of specific demand, and all the other quite a few employing neoprene bearings.For the non-bearing of putting more energy into, due to the Incoercibility of rubber, rubber deformation only has lateral expansion, inevitable in the larger protruding bulging phenomenon of its surrounding appearance, rubber at protruding drum place can produce larger stretcher strain, thereby it is aging to produce stress, for fear of occur this rough sledding, generally adopt at present adding the steel plate lateral expansion for layer constraint rubber of putting more energy in rubber.But in order to ensure that laminated rubber bearing has enough intensity and lateral deformation that can operative constraint rubber at normal service condition lower steel plate, the thickness of putting more energy into of the steel plate in bearing is generally not less than 2mm, and rubber layer thickness between steel plate will meet certain requirements.Because steel plate does not possess lateral deformation capacity, the horizontal movement ability of board-like bearing can only realize by the lateral deformation of rubber.Consider that the gross thickness of laminated rubber bearing light plate accounts for the large percentage of bearing overall height, in the time that the horizontal movement demand of bearing is larger, the height of bearing must increase obviously.In addition, the mass density of steel plate is larger, and this has also caused the overall weight of laminated rubber bearing larger, causes puzzlement to transport and the installation of bearing.
The more important thing is, under geological process, neoprene bearing bears larger pressure and cuts synergy, but its shear strain ability is limited, and neoprene bearing is cut up owing to not rolling, the destruction such as cause rubber to come unstuck, steel plate is broken.
Therefore,, for above variety of problems, we have designed a kind of novel fine and closely woven high-strength steel mesh laminated rubber bases of putting more energy on the basis of neoprene bearing.
Summary of the invention
For overcome non-put more energy into neoprene bearing exist lateral deformation excessive, the problems such as laminated rubber bearing horizontal movement rubber limited, that may exist comes unstuck, steel plate is broken, the utility model provides one to have constraint rubber deformation, possess higher vertical bearing capacity, meet normal usage function, and can under earthquake or great percussion, be out of shape, rotate by bearing, reduce the light-duty Novel rubber support of superstructure seismic forces on substructure impact.
The fine and closely woven high-strength steel mesh the utility model proposes laminated rubber bases of putting more energy into.Formed by protection rubber 1, inner rubber 2 and fine and closely woven high-strength steel mesh 4; described high-strength fine and closely woven steel screen layer 4 connects to form frame construction by the high tensile steel wire 3 being mutually vertically staggered; described inner rubber 2 and high-strength fine and closely woven steel screen layer 4 are alternately arranged and are bonded from top to bottom; described high-strength fine and closely woven steel screen layer 4 forms reliable bonding with inner rubber 2 through sulfuration, alternately arranges that high-strength fine and closely woven steel screen layer 4 and inner rubber 2 peripheries after bonding are enclosed with protection rubber 1.
In the utility model, described fine and closely woven high-strength steel mesh 4 is worked out by high tensile steel wire 3 colligations, welding or the mode of alternately interting.
The utility model adopts with the alternative traditional laminated rubber bearing light plate of fine and closely woven high-strength steel mesh, and fine and closely woven high-strength steel mesh is embedded in the lateral deformation of rubber bodies internal constraint rubber, and the necessary vertical rigidity of neoprene bearing and supporting capacity are provided.High-strength steel mesh constraint system connects each layer of rubber mutually, and bearing rubber bodies effective layer thickness ratio increases obviously.Under normal operating condition, bearing has the function identical with traditional laminated rubber bearing.Under compared with small earthquake effect, bearing generation shear strain, consumed energy, simultaneously, rubber bodies can provide the girder that restoring force makes bridge in the mechanism of earthquake, can effectively reset with geological process rear support and substantially not depart from jointly, thereby ensures the traffic capacity after bridge shake; Under severe earthquake action, because fine and closely woven high-strength steel mesh has good deformability, energy and the good collaborative work of rubber bodies, can there is moderate finite deformation until upper and lower contact surface comes to nothing and then starts rolling in the utility model, beam body can not reduce suddenly because of bearing generation unstable failure, avoid the seismic forces of superstructure to be delivered to substructure, played function of shock insulation, guaranteed bridge structure safe.Simultaneously, because the utlity model has isotropic feature, bearing is applied widely, and can play a role to the earthquake motion input from all directions, and, compared to traditional laminated rubber bearing, same bearing performance, height of the present utility model more low weight is lighter, and this just facilitates transport and the installation of bearing.
Accordingly, the utility model proposes high tensile steel wire is compiled into fine and closely woven high-strength steel mesh, the steel plate of alternative laminated rubber bearing is put into rubber mold and is poured into rubber molding, is protected at skin parcel rubber.
In the utility model, fine and closely woven high-strength steel mesh is compiled into close net by high tensile steel wire.
The beneficial effects of the utility model are:
1) the fine and closely woven high-strength steel mesh in scheme neoprene bearing has retrained the lateral deformation producing when rubber is subject to load effectively, thereby avoids rubber lateral expansion to cause the excessive acceleration of tensile stress ageing of rubber, has improved vertical bearing capacity and vertical rigidity.
2) horizontal rigidity of scheme neoprene bearing is more soft compared to traditional laminated rubber bearing, in the time that the lateral deformation of scheme bearing is excessive, fine and closely woven high-strength steel mesh can be out of shape with rubber, even can be with rubber bodies one side rolling, and can there is not gauze wire cloth degumming phenomenon in scheme bearing yet.
3) in scheme bearing, the thickness of fine and closely woven high-strength steel mesh is less than the steel plate of laminated rubber bearing, and compared with the laminated rubber bearing of equal height, the scheme bearing inside number of plies of putting more energy into is more, better to the effect of contraction of rubber.Meanwhile, owing to having saved thick and heavy steel plate, scheme bearing is more light.
4) in scheme bearing, fine and closely woven high-strength steel mesh has very strong deformability, under geological process, allow scheme bearing generation moderate finite deformation until upper and lower contact surface comes to nothing and then starts rolling, beam body can not reduce suddenly because of bearing generation unstable failure, avoid the seismic forces of superstructure to be delivered to substructure, play function of shock insulation, guaranteed bridge structure safe.
In a word, the utility model is applicable on the building of railway bridge, road bridge, urban viaduct and various suspension frame structures and so on, and improve and improved the performance of ordinary rubber bearing to a certain extent, distortion and the shock insulation ability of bearing are effectively improved, the shortcoming of having avoided ordinary rubber bearing to exist.

Detailed description of the invention
For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present utility model and beneficial effect more, applicant elaborates the mode with embodiment below by reference to the accompanying drawings, but be not all the restriction to the utility model scheme to the description of embodiment, any done according to the utility model design only for pro forma but not substantial equivalent transformation all should be considered as the technical solution of the utility model category.
Embodiment 1: ask for an interview Fig. 1, Fig. 2, Fig. 3, fine and closely woven high-strength steel mesh is put more energy into laminated rubber bases by protecting rubber 1, inner rubber 2 and fine and closely woven high-strength steel mesh 4 to form.Fine and closely woven high-strength steel mesh 4 is worked out by high tensile steel wire 3, then fine and closely woven one deck rubber one deck high-strength steel mesh 4 is positioned in mould, and finally sulfuration forms entirety, and appearance is wrapped with protection rubber 1.
In the time that scheme bearing bears vertical load, rubber expands laterally, but gather fine and closely woven high-strength steel mesh 4 because inner rubber 2 is interior, effectively retrain the lateral expansion of rubber, vertical compression reduces, necessary vertical rigidity when thereby scheme bearing obtains normal use has been avoided the excessive generation stress of rubber tensile stress problem of aging simultaneously; In the time that scheme bearing is subject to horizontal force action, rubber generation shear strain, meets its horizontal movement needs.
Under earthquake or great percussion, the shear strain of scheme bearing is larger, the upper and lower contact surface of scheme bearing edge starts to come to nothing, in the time that distortion further increases, its whole surface all can depart from roof and floor completely and be the state of toppling, even can roll by occurred level, avoided the earthquake of superstructure or percussion to be delivered to substructure, ensure structural safety.Because fine and closely woven high-strength steel mesh 4 has very strong deformability, lose original form even if scheme bearing occurs to roll, fine and closely woven high-strength steel mesh 4 still can with inner rubber 2 collaborative works, do not affect original performance of scheme bearing.
