Description

A kind of high-damp rubber support
Technical field
The utility model belongs to bearing technical field, particularly relates to a kind of bridge, high-damp rubber support that building engineering field uses.
Background technology
China is seismic activity one of country the most frequently, therefore carries out seismic isolation design to building and bridge and seems extremely important.At present, conventional rubber-like shock isolating pedestal main body is by multilayer rubber and steel plate is superimposed forms through high temperature vulcanized bonding, the viscosity of its elastomeric material is large, and self can absorb energy, has larger ductility, can when earthquake extending structure natural vibration period, reduce geological process power, utilize its energy dissipation behavior to play and subtract function of shock insulation, and total damping can be changed by the ratio of adjustment packing material, make it that there is stronger energy dissipation capacity, compared with the viscous damping of high equivalent weight, play the effect better subtracting shock insulation.High-damp rubber support volume is smaller, can save usage space, constructs also more convenient, so the application of high-damp rubber support is more and more extensive.But, no matter natural rubber bearing (LNR) or common high-damp rubber support (HDR) etc., it is with bolts that it is fixedly connected with mode, as shown in Figure 1, the upper bracket mechanism that the structure forming high-damp rubber support is made up of pre-embedded steel slab at the bottom of beam 1, upper bracket plate 2 and upper strata shrouding 3, the undersetting mechanism be made up of pier top pre-embedded steel slab 9, lower support plate 8 and lower floor's shrouding 7, be fixed on wrapped up by rubber lamination 5 between the two step up the superimposed functional entity formed of steel plate 6; Wherein, what embedded board at the bottom of beam and being provided with between upper bracket plate, between pier top embedded board and lower support plate was made up of anchor bolt 10, sleeve 11 and screw rod 12 is connected and fixed mechanism, is provided with the stationary positioned mechanism be made up of bolt 13 between upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding.In this structure, upper bracket plate 1 and upper strata shrouding 2 are linked together by connecting bolt 13, its process for machining and manufacturing is more loaded down with trivial details, also relatively bother when again bearing being assembled, due to the problem of mismachining tolerance, when multiple bolt screws, can cause the upper bracket plate of bearing and upper strata shrouding not parallel, and cause the overall out-of-flatness of bearing, the discontinuity of bolt when screwing, and the pretightning force of bolt also can cause the stressed also uneven of upper bracket plate and upper strata shrouding, the early damage for bearing has buried hidden danger.
Utility model content
The purpose of this utility model be just to provide a kind of bearing overall performance good, install, convenient disassembly, horizontal force is even, effectively can weaken the high-damp rubber support of different earthquake frequency vibration on the impact of building structure.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of high-damp rubber support, its structure comprises
The upper bracket mechanism be made up of embedded board, upper bracket plate and upper strata shrouding at the bottom of beam,
The undersetting mechanism be made up of pier top embedded board, lower support plate and lower floor's shrouding,
Be fixed on and step up the superimposed functional entity formed of steel plate by r c between the two; Wherein
At the bottom of described beam between embedded board and upper bracket plate, be provided with between pier top embedded board and lower support plate be made up of bolt, sleeve be connected and fixed mechanism, be provided with stationary positioned mechanism between described upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding; It is characterized in that, described stationary positioned mechanism is the some fixing holes be arranged between described upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding and the border matched is that smooth alignment pin is formed.
In addition, the additional technical feature forming above-mentioned high-damp rubber support also comprises:
---described fixing hole inwall is smooth cylinder;
---described fixing hole inwall is provided with thread mechanism;
A kind of high-damp rubber support provided by the utility model compared with prior art has the following advantages: due to between upper bracket plate with upper strata shrouding and lower support plate be connected by alignment pin with the stationary positioned between lower floor shrouding, it is structure and manufacturing process is simple, centering is good not only, but also has the feature of installation, convenient disassembly; More importantly, because the border wall of alignment pin is smooth, to make between connected upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding horizontal force even, and make support body structure smooth; Overcome in prior art and connect produced pretightning force by bolt, the defect that the early stage internal construction of bearing can be caused to destroy, substantially prolongs the bearing life-span; And the horizontal movement that smooth alignment pin can also provide certain corner and cause due to reasons such as temperature deformations, and effectively weaken the impact of different earthquake frequency vibration on building and bridge construction.
Accompanying drawing explanation
Fig. 1: be the structural representation of prior art high-damp rubber support;
Fig. 2: be the structural representation of the high-damp rubber support that the utility model provides.
Detailed description of the invention
Be described further below in conjunction with the concrete structure of the drawings and specific embodiments to a kind of high-damp rubber support provided by the utility model.
As shown in Figure 2, for the structural representation of a kind of high-damp rubber support provided by the utility model, namely form seat structure and comprise the upper bracket mechanism be made up of pre-embedded steel slab at the bottom of beam 1, upper bracket plate 2 and upper strata shrouding 3, the undersetting mechanism be made up of pier top pre-embedded steel slab 9, lower support plate 8 and lower floor's shrouding 7, be fixed on wrapped up by rubber lamination 5 between the two step up the superimposed functional entity formed of steel plate 6; Wherein, embedded board at the bottom of beam and be provided with between upper bracket plate, between pier top embedded board and lower support plate to be made up of anchor bolt 10, sleeve 11 and screw rod 12 and be connected and fixed mechanism respectively at beam body and bridge pier, be provided with stationary positioned mechanism between upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding, this stationary positioned mechanism is the fixing hole 14 of the some inner wall smooths be arranged between above-mentioned upper bracket plate and upper strata shrouding and between lower support plate and lower floor's shrouding and is fixed on wherein and the border matched is smooth alignment pin 15 forms.
In addition, forming above-mentioned high-damp rubber support overall performance to improve further, the large horizontal movement that high earthquake magnitude earthquake is formed can be adapted to, its fixing hole inwall is provided with screw thread 16, namely can greatly improve its displacement effect.
