Description
Technical field
The utility model relates to the ancillary technique of building the road, and is specially a kind of cement concrete pavement space joint.
Background technology
Under normal circumstances, fix after rear cement-concrete road, road surface can be cut out to the space of a lot of rules, play the effect at shrinkage joint, object is because concrete easily shrinks, after a period of time, cement concrete pavement there will be a lot of irregular cracks, so, cut out in advance regular crack, prevent that turtle shell shape crack from appearring in rigid pavement.But due to the long term of the natural causes such as rainwater, purt slurry phenomenon appears in sub-layer, the crack place of rigid pavement is usually first destroyed, and the reinforcing bar at crack place, also by heavy corrosion, has had a strong impact on the application life of concrete road.
Summary of the invention
The purpose of this utility model is to prevent the corrosion failure effect at measures of cracks on concrete pavement place, and a kind of cement concrete pavement space joint is provided.
The utility model is to adopt following technical scheme to realize:
A kind of cement concrete pavement space joint, comprises the space fittings body that utilizes rubber to prepare, and has fixedly crossed some steel fibres and bending is undulatory finer wire in described space fittings body, and space fittings body is all stretched out at the two ends of described steel fibre and finer wire.
In the time laying cement-concrete road, design in advance regular space, concrete road is that one section one section continuity is laid, between section and section, it is road surface space, lay so in the afterbody template of concrete road the last period and place this space joint, the steel fibre and the finer wire that are positioned at so rubber space fittings body one side are squeezed into concrete road, and the steel fibre that is positioned at a side is connected rubber space joint and concrete road with finer wire; While laying next section concrete road, be positioned at so the steel fibre of this rubber space fittings body opposite side and finer wire and squeeze into the head on next section concrete road.Wherein, because steel fibre all becomes ripple bending with finer wire, formed firm being connected with concrete road.Like this; in the space of rubber space fittings body between the two section concrete roads that design; due to the elastic reaction of rubber itself; this position had both had the effect of concrete road surface expansion joint; prevent that concrete road from producing other non-design cracks; also there is waterproof, connect fixed effect, the space place of rigid pavement is protected, effectively prevent the corrosion fragmentation of natural conditions.
The utility model is reasonable in design, simple in structure, makes cement concrete pavement be filled in real sealing at space place, keeps attractive in appearance, increases the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1-space fittings body, 2-steel fibre, 3-finer wire.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of cement concrete pavement space joint, as shown in Figure 1, comprise the space fittings body 1 that utilizes rubber to prepare, described space fittings body 1 is interior has fixedly crossed some steel fibres 2 and bending is undulatory finer wire 3, and space fittings body 1 is all stretched out at the two ends of described steel fibre 2 and finer wire 3.
Described steel fibre 2 and finer wire 3 are spaced apart.Space fittings body 3～5cm is stretched out respectively at the two ends of described steel fibre 2; Space fittings body 5～15cm is stretched out respectively at the two ends of described finer wire 3.The extension elongation of steel fibre and finer wire ensures in its cement concrete that can be inserted into space two ends, makes safe the linking into an integrated entity of concrete of rubber space fittings body and both sides.The elastic reaction of rubber itself, makes this seam can play the effect at shrinkage joint, also can make this seam by the real sealing of rubber stopper, waterproof, anticorrosion.
Claims (3)
1. a cement concrete pavement space joint, it is characterized in that: comprise the space fittings body (1) that utilizes rubber to prepare, fixedly crossed some steel fibres (2) in described space fittings body (1) and bending is undulatory finer wire (3), space fittings body (1) is all stretched out at the two ends of described steel fibre (2) and finer wire (3).
2. cement concrete pavement space joint according to claim 1, is characterized in that: space fittings body (1) 3～5cm is stretched out respectively at the two ends of described steel fibre (2); Space fittings body (1) 5～15cm is stretched out respectively at the two ends of described finer wire (3).
3. cement concrete pavement space joint according to claim 1 and 2, is characterized in that: described steel fibre (2) and finer wire (3) are spaced apart.
