Background technology
In design of building structures, effectively earthquake disaster mitigation of shock isolating pedestal is set.
According to the requirement of national regulation " seismic design provision in building code " (GB 50011-2010), at present China in base isolation, to apply maximum be laminated steel plate rubber earthquake isolation support, it has good shock insulation ability, but its deadweight is large and cost is relatively high, mainly for the heavily loaded design of building structures of high level, be not too applicable in median low structure.Therefore, a kind of cheap for middle low-rise building shock insulation development, isolation property is good, conducts oneself with dignity little, and the bearing of easy construction will be an important topic.
Utility model content
The purpose of this utility model is to provide a kind of alternating layers rubber earthquake isolation support, solve existing laminated steel plate rubber earthquake isolation support cost higher, and the large and complex manufacturing technology of bearing quality, is unfavorable for the technical problem of promoting and using at middle low-rise building.
For achieving the above object, the utility model adopts following technical scheme:
A kind of alternating layers rubber earthquake isolation support, it is the support body by middle part, the upper envelope steel plate that main body end face upside arranges, the lower envelope steel plate that main body bottom surface downside arranges, and be coated on support body, the rubber cover of upper envelope steel plate and lower envelope steel plate peripheral side together forms through over cure bonding, described support body comprises the each at least a slice nylon sheet arranging in steel plate and steel plate both sides and a slice nylon cloth at least, described nylon sheet and nylon cloth are superimposed, described steel plate, between nylon sheet and nylon cloth, all separate with sheet rubber, the top layer of described support body and the bottom are all with the superimposed end of sheet rubber.
The cross section of described alternating layers rubber earthquake isolation support is circle, rectangle or other regular polygon.
The thickness of described nylon sheet is 1.7～2.2mm.
The thickness of described nylon cloth is 1.7～2.2mm.
Described upper envelope steel plate and the prepared screw-bolt hole that is respectively equipped with equidistant layout, is fixedly connected with up-down structure on lower envelope steel plate.
Compared with prior art the utlity model has following characteristics and beneficial effect:
It is higher that the utility model has overcome existing laminated steel plate rubber earthquake isolation support cost, and the large and complex manufacturing technology of bearing quality, is unfavorable for the technical problem of promoting and using at middle low-rise building.The utility model adds density compared with the little nylon sheet of steel plate and nylon cloth in support body structure, replaces the steel plate quantity in unit volume, has reduced the deadweight of bearing.
In one timing of steel plate number, reduce the use of nylon cloth, increase the use of nylon sheet, can increase the horizontal rigidity of bearing entirety, can better retrain the horizontal distortion of the upper and lower both sides of nylon sheet sheet rubber, bearing entirety shock insulation energy dissipation capacity is increased, improved vertical rigidity simultaneously, and then improved the vertical bearing capacity of bearing entirety.Bearing rigidity can also adjust to meet by changing the number of plies thickness of nylon cloth, nylon sheet, sheet rubber and steel plate the shock insulation requirement of median low structure.
