Abstract
The utility model relates to a concrete road surface is polyurethane sword hemp fibre board for expansion joint (E. J. ) belongs to highway and urban road construction technical field, for solving the problem design that the concrete road surface construction used the expansion joint (E. J. ) board to waste time and energy. The utility model discloses constitute by wrapping up layer, bearing stratum and bearing course, the parcel layer be the asphalt felt, be located polyurethane sword hemp fibre board's the outside, the bearing stratum be polyurethane fiber layer, forming by polyurethane matrix and the suppression of modified sisal fiber, the bearing course be the rubber layer, be located polyurethane sword hemp fibre board's centre. The utility model discloses simple structure has good tensile properties, impact resistance and corrosion resistance, is the ideal component that is applicable to the cement concrete pavement expansion joint (E. J. ), and engineering practicability is strong.
Description
Technical field
This utility model belongs to highway and urban road construction technical field, is specifically related to a kind of polyurethane sisal fiber plate, particularly relates to a kind of concrete road surface expansion joint polyurethane sisal fiber plate.
Background technology
Spatial gaps reserved when road surface expansion joint (E.J.) is construction, it is therefore an objective to provide the leeway extended for expanding of concrete slab, thus avoiding producing excessive thermal stress.Stretching seam concrete slab top, position placement tooled joint lath during construction, after concrete setting, the cover-strip stretching seam to be extracted, then pour into joint sealing material, waste time and energy, affect construction speed.Simultaneously, the section that expansion joint (E.J.) spacing is shorter, in use often occur that expansion joint (E.J.) gap increases, the joint slab ability making dependence embedding effect is substantially reduced, and because the foreign material such as joint sealing material is difficult to keep its usefulness, sandstone are convenient to fall in seam, cause the concrete of seaming zone to produce cataclastic failure when swelling blockage, or arch upward, increase the later period maintenance cost of engineering.The natural characteristics such as sisal fiber material has tough and hard wear resistant, and quality is hard and soft, high resilience, will not harden under low temperature, and brittle failure is not gone mouldy, corrosion-resistant, clean, pollution-free, antistatic.It is thus desirable to a kind of new concrete road surface expansion joint polyurethane sisal fiber plate of utility model, to be effectively improved the construction speed of concrete road surface, reduce later period maintenance, to effectively facilitate the development of highway and urban road construction.
Summary of the invention
The purpose of this utility model is to provide a kind of concrete road surface expansion joint polyurethane sisal fiber plate, this polyurethane sisal fiber plate not only can be effectively improved the construction speed of concrete road surface, reduce later period maintenance expense, and simple in construction, easy construction, practical, Technological Economy is feasible.
Technical solution adopted in the utility model is: a kind of concrete road surface expansion joint polyurethane sisal fiber plate, it is made up of integument, supporting course and bearing course；Described integument is asphalt felt, is positioned at the outside of polyurethane sisal fiber plate；Described supporting course is polyurethane fiber layer, polyurethane matrix and modified sisal fiber suppress forming；Described bearing course is rubber layer, is positioned at the centre of polyurethane sisal fiber plate.
Construction usage method of the present utility model is: first polyurethane matrix and modified sisal fiber are suppressed according to the designing requirement of road construction, complete polyurethane fiber layer, rubber layer is placed in the middle of two-layer polyurethane fiber layer, asphalt felt is placed in the outside of two-layer polyurethane fiber layer, asphalt felt is toasted to melting with flame projector, compacting, so as to combine；Then the polyurethane sisal fiber plate of corresponding length and height is intercepted, according to designing requirement at the fixing polyurethane sisal fiber plate of the relevant position of road construction construction；Finally polyurethane sisal fiber plate and concrete are carried out formed by integrally casting.
Operation principle of the present utility model is: a kind of concrete road surface expansion joint polyurethane sisal fiber plate, it is made up of Colophonium carpet veneer, polyurethane fiber layer and rubber layer, having tough and hard wear resistant, quality is hard and soft, high resilience, will not harden under low temperature, the feature of brittle failure, it is possible to the effectively thermal stress of buffering concrete generation, and polyurethane sisal fiber plate and concrete formed by integrally casting, need not take out, accelerate construction speed and workload.
The beneficial effects of the utility model are: a kind of concrete road surface expansion joint polyurethane sisal fiber plate, can be integrated in company with once-pouring of concrete when concrete pavement construction, need not take out, improve construction speed, solve the problem that wastes time and energy when expansion joint plate uses, and simple in construction, easy construction, practical, Technological Economy is feasible.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As shown in FIG. 1 to 3, this utility model one concrete road surface expansion joint polyurethane sisal fiber plate, it is made up of integument, supporting course and bearing course；Described integument is asphalt felt 3, is positioned at the outside of polyurethane sisal fiber plate；Described supporting course is polyurethane fiber layer 2, polyurethane matrix and modified sisal fiber suppress forming；Described bearing course is rubber layer 1, is positioned at the centre of polyurethane sisal fiber plate.
During use, first according to the designing requirement of road construction, polyurethane matrix and modified sisal fiber are suppressed, complete polyurethane fiber layer 2, rubber layer 1 is placed in the middle of two-layer polyurethane fiber layer 2, asphalt felt 3 is placed in the outside of two-layer polyurethane fiber layer 2, toasting asphalt felt 3 to thawing with flame projector, compacting, so as to combine；Then the polyurethane sisal fiber plate of corresponding length and height is intercepted, according to designing requirement at the fixing polyurethane sisal fiber plate of the relevant position of road construction construction；Finally polyurethane sisal fiber plate and concrete 4 are carried out formed by integrally casting.
