Abstract
The invention relates to a lamination bitumen vibration isolation cushion which is a low cost vibration isolation cushion suitable for houses in villages and small towns. The vibration isolation cushion comprises a bitumen layer and a metal wire mesh; the metal wire mesh and the bitumen layer are alternately laminated and adhered, and adhesive layers are coated on the upper surface and the lower surface of the bitumen layer; the lamination sequence of the vibration isolation cushion is: the bitumen layer, the metal wire mesh, the bitumen layer and the metal wire mesh, a plurality of layers are laminated according to the sequence, the uppermost layer is the bitumen layer, then a bitumen protective layer is added around the side surface to form the vibration isolation cushion. The vibration isolation cushion has the advantages of low cost and simplicity in installation process, is paved between an upper part structure and a foundation when used to form plane support, and meanwhile has better damping property if local damage does not influence the safety of the whole building.
Description
Technical field:
The present invention relates to a kind of shock insulation pad, is a kind of low cost shock insulation pad that is applicable to the house, villages and small towns.
Background technology:
Shock insulation is to alleviate the effective way that building suffers seismic damage; In the existing building seismic isolation technology; Base isolation is used the most general; And what in base isolation, play a major role is a kind of rubber earthquake isolation support; It is superimposed to form by steel plate and sheet rubber each other; But there is following problem in rubber earthquake isolation support in the shock insulation in house, villages and small towns is used: 1, price is expensive, cost is high; 2, the villages and small towns building construction is generally simpler, and neoprene bearing is constructed, mounting process is complicated; Cause rubber earthquake isolation support to be difficult in the building of villages and small towns, promote the use of thus.
Summary of the invention:
The technical problem that the present invention will solve is: provide a kind of and can satisfy certain damping requirement, cheap, the low cost shock insulation pad that is applicable to the house, villages and small towns.
The technical scheme that addresses the above problem is: a kind of shock insulation pad; Comprise bitumen layer and wire mesh sheet; The bitumen layer that wire mesh sheet and upper and lower surface the scribble adhesive layer bonding that is superimposed each other; Superimposed from bottom to top order is successively: bitumen layer, wire mesh sheet, bitumen layer, wire mesh sheet; Order coincidence number layer like this; The superiors finish with bitumen layer, add the pitch topping in side periphery more afterwards, thereby are integrally formed.
Said adhesive layer is the adhesive bitument primer that is coated on the bitumen layer surface with coated form.
The pitch of said bitumen layer is existing SBS modified bitumen or APP modified bitumen on the market.
Described wire mesh sheet is existing stainless steel or a copper mesh sheet on the market.
The present invention's laminated bituminous shock insulation pad is compared with the rubber earthquake isolation support that oneself has, and the house, villages and small towns is had following advantage:
Laminated bituminous shock insulation pad price cost is generally 15～20 yuan/m
2, and the quotation of rubber earthquake isolation support is at 100 yuan/m
2More than; Adopt the house of technical scheme of the present invention; Compare with the house that adopts rubber earthquake isolation support; Integral body can drop to 1/5 of former cost at least; And for the house of strip foundation; Can between superstructure and basis, all lay the shock insulation pad during use, on the one hand, the foundation that is made up of this shock insulation pad is that face supports; If local damage can't influence the safety of whole building; On the other hand, it is simple to lay mounting process, has further reduced cost; Simultaneously; Whole shock insulation pads are embedded in the soil layer in the use, and variations in temperature is little, and is more favourable to durability.
Below in conjunction with accompanying drawing and embodiment the technical characterictic of the present invention's laminated bituminous shock insulation pad is done further explanation.
Description of drawings:
Fig. 1: the structural representation of laminated bituminous shock insulation pad of the present invention.
Fig. 2: the vertical view of laminated bituminous shock insulation pad of the present invention.
The hysteresis loop of Fig. 3: embodiment 1 laminated bituminous shock insulation pad.
The hysteresis loop of Fig. 4: embodiment 2 laminated bituminous shock insulation pads.
Among the figure: 1, bitumen layer, 2, wire mesh sheet, 3, adhesive layer, 4, the pitch topping
The specific embodiment:
Embodiment 1:
A kind of cross section is rectangular laminated bituminous shock insulation pad; This shock insulation pad is by bitumen layer 1, wire mesh sheet 2 bonding that is superimposed each other of band adhesive layer 3; Superimposed from bottom to top order is successively: bitumen layer 1, wire mesh sheet 2, bitumen layer 1, wire mesh sheet 2; Coincidence number layer like this; The superiors finish with bitumen layer 1; Add pitch topping 4 in side periphery more afterwards, thereby be integrally formed (referring to Fig. 1, Fig. 2).During use, directly it is laid between basis and the superstructure.
The pitch of said bitumen layer 1 is the SBS modified bitumen, bitumen layer thickness 3mm; The stainless steel cloth sheet that described wire mesh sheet 2 adopts specification 14 * 14 order numbers, wire mesh sheet thickness 0.5mm; Said adhesive layer 3 is the adhesive bitument primers that are coated on bitumen layer 1 upper and lower surface with coated form; Said pitch topping 4 thickness 2mm.Superimposed 13 layers altogether on present embodiment laminated bituminous shock insulation pad, overall height is 24mm.
Embodiment 2:
A kind of cross section is rectangular laminated bituminous shock insulation pad; This shock insulation pad is by bitumen layer 1, wire mesh sheet 2 bonding that is superimposed each other of band adhesive layer 3; Superimposed from bottom to top order is successively: bitumen layer 1, wire mesh sheet 2, bitumen layer 1, wire mesh sheet 2; Coincidence number layer like this; The superiors finish with bitumen layer 1; Add pitch topping 4 in side periphery more afterwards, thereby be integrally formed (referring to Fig. 1, Fig. 2).During use, directly it is laid between basis and the superstructure.
The pitch of said bitumen layer 1 is the APP modified bitumen, bitumen layer thickness 3mm; The copper mesh sheet that described wire mesh sheet 2 adopts specification BWG24, wire mesh sheet thickness 1mm; Said adhesive layer 3 is the adhesive bitument primers that are coated on bitumen layer 1 upper and lower surface with coated form; Said pitch topping 4 thickness 2mm.Superimposed 13 layers altogether on present embodiment laminated bituminous shock insulation pad, overall height is 27mm.
Above-mentioned two embodiment laminated bituminous shock insulation pads, in the cost that reduces cost, the hysteresis stable performance, damping ratio remains on 0.227～0.394 scope, has shock insulation energy dissipation capacity preferably, and shown in Figure 3 is the hysteresis loop of embodiment 1 laminated bituminous shock insulation pad.Shown in Figure 4 is the hysteresis loop of embodiment 2 laminated bituminous shock insulation pads.
As a kind of conversion of the embodiment of the invention, bitumen layer thickness, wire mesh sheet thickness and the overlapping layers in the said laminated bituminous shock insulation pad is several can be adjusted according to needing.
