Abstract
The invention relates to a fiber and polytetrafluoroethylene plate rubber combined shock insulation support, and belongs to the field of shock insulation for room buildings. The support mainly comprises rubber layers, fiber layers and polytetrafluoroethylene plates which are staggered and laminated according to a sequence of a first rubber layer, one of the polytetrafluoroethylene plates, a second rubber layer, one of the fiber layers and a third rubber layer; a plurality of layers are laminated, and the rubber layer is arranged on the top, so that a laminated body is formed; end steel plates are respectively arranged on the upper end face and the lower end face of the laminated body, and a rubber protection layer is arranged around the lateral direction of the laminated body; and the final support is formed by vulcanization and bonding. The support is light in weight and low in assembly cost; and the vertical rigidity and the bearing capacity of the support can be changed by adjusting the number of polytetrafluoroethylene plates in the support.
Description
Technical field
The present invention relates to a kind of fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal, belong to building construction shock insulation field.
Background technology
Seismic isolation technology can effectively improve the shock resistance in house, and it utilizes the earthquake isolating equipment that is arranged between superstructure and the basis to absorb seismic energy usually, prolongs the vibration period, reduces the superstructure earthquake response.Area, China villages and small towns earthquake-resistant building ability is generally relatively poor, and it is serious in earthquake, to collapse, and common earthquake isolating equipment is a kind of lamination steel rubber abutments at present; It is from great, cost is high, is primarily aimed at high-rise heavily loaded design of building structures; And the house, villages and small towns is generally in the majority with middle low layer; If the lamination steel rubber abutments is used for the villages and small towns house shock insulation, be a kind of waste unavoidably, this just presses for a kind of earthquake isolating equipment to middle low-rise building of development.
Summary of the invention
To the problems referred to above; The object of the invention is to provide a kind of fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal that can in the low-rise building of villages and small towns, generally use, and this bearing is from heavy and light, and installation cost is low; Simultaneously can be through regulating vertical rigidity and the bearing capacity that the inner polyfluortetraethylene plate quantity of bearing changes bearing; To satisfy the villages and small towns shock insulation demand in number of plies house from different places, rationally select bearing for use thereby reach, the purpose of economical with materials.
For realizing above-mentioned purpose, the present invention takes following technical scheme:
A kind of fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal; It is characterized in that: it mainly comprises rubber layer, fibrage and polyfluortetraethylene plate three parts; The three is staggered superimposed, and superimposed from top to bottom order is followed successively by: rubber layer, polyfluortetraethylene plate, rubber layer, fibrage, rubber layer, and so order coincidence number layer finally finishes with rubber layer; Thereby form superimposed body; Add the end steel plate respectively in the upper and lower end face of superimposed body afterwards, and add rubber cover towards periphery, form through the over cure bonding at last on superimposed side.
Described fibrage is made up of single layer fibre cloth, perhaps the special-purpose adhesive of fiber single layer fibre cloth is made up of for bonding several layers, and described polyfluortetraethylene plate is the polyfluortetraethylene plate through how receiving after the chemical treatment.
Described fiber-the cylindrical or cuboid of polyfluortetraethylene plate building rubber compound shock isolating pedestal.
Described end steel plate is provided with the prepared screw-bolt hole of equidistant layout, is used for firmly being connected with up-down structure.
Described rubber cover and bearing inner rubber fuse, the aging or corrosion of protection internal fiber cloth and polyfluortetraethylene plate.
The density of polyfluortetraethylene plate is generally at 2.10 ~ 2.30g/cm
3Between, be 1/3 ~ 1/4 of steel plate density approximately, the density of cloth is 1.3g/ cm
3, be 1/6 of steel plate density approximately, so fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal has alleviated deadweight greatly, made things convenient for to produce and installed, provide cost savings.Test simultaneously shows; Through regulating the quantity of the inner polyfluortetraethylene plate of bearing, can change fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal vertical rigidity and bearing capacity, and also have shock insulation energy dissipation capacity preferably; Thereby the purpose of low-rise building shock insulation in satisfying is like Fig. 3 ~ Fig. 4.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.

The specific embodiment
Embodiment
As depicted in figs. 1 and 2; A kind of fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal, this bearing comprise rubber layer 2, polyfluortetraethylene plate 3 and fibrage 4 three parts, and the three is staggered superimposed; Superimposed from top to bottom order is followed successively by: rubber layer 2, polyfluortetraethylene plate 3, rubber layer 2, fibrage 4, rubber layer 2; So order coincidence number layer finally finishes with rubber layer, thereby forms superimposed body, adds end steel plate 1 afterwards respectively in the upper and lower end face of superimposed body; And add rubber cover 5 towards periphery on superimposed side, form through the over cure bonding at last.
Superimposed 35 layers altogether of present embodiment shock isolating pedestals, wherein enhancement Layer is 17 layers, comprises 9 strata tetrafluoroethene flaggies and 8 layers of fibrage.When alleviating deadweight, energy-dissipating property is stable, and equivalent damping ratio can reach 9.8%, and Fig. 3 is the hysteresis loop of embodiment shock isolating pedestal shearing strain 250%, and Fig. 4 is the vertical pressure displacement curve of embodiment shock isolating pedestal.
The foregoing description shock isolating pedestal diameter D is 320mm, high 110mm, and rubber layer thickness 3.1mm wherein, the polyfluortetraethylene plate layer thickness is 2mm, and end steel plate thickness is 10mm, and rubber cover thickness is 10mm.Described polyfluortetraethylene plate is to scribble the polyfluortetraethylene plate of bonding adhesive through how receiving surface after the chemical treatment; 6 prepared screw-bolt holes are arranged on the described end steel plate, are evenly to distribute on the circumference of 260mm at diameter, are used for during installation firmly being connected with up-down structure; Described rubber cover and bearing inner rubber fuse, and protect the aging and corrosion of inner polyfluortetraethylene plate.
As a kind of conversion of the embodiment of the invention, the geomery parameter in said fiber-polyfluortetraethylene plate building rubber compound shock isolating pedestal and overlapping layers is several can adjust according to requirement of engineering.
