Abstract
The utility model belongs to maintenance equipment for road construction, and particularly relates to a special quick road slab for expansion joint construction. The special quick road slab comprises a panel in an arch structure straddled on both sides of an expansion joint and a lining plate fixed in the inner surface of the panel and arranged in the same direction with the arch structure. The special quick road slab solves the problem of traffic jam during the existing bridge expansion joint construction, and has the advantages of being simple in structure, convenient to install, stable for running, synchronous for construction and use, long in service life, and the like.
Description
Technical field
The utility model belongs to road construction maintenance equipment, refers to a kind of shrinkage joint special-purpose fast-assembling road slab of constructing especially.
Background technology
Present speedway (especially main line) maintenance of surface work is heavy day by day, be that example describes with Shijiazhuang-Anyang section speedway (be called for short stone peace at a high speed) traffic, this section speedway total length 216.05km, be open to traffic nearly 15 years from December, 1997, because vehicle flowrate is big, reasons such as transportation transfinite, cause bridge expanssion joint the girder steel fracture constantly to occur, concrete breaking, check crack, diseases such as hole groove, especially in recent years, vehicle flowrate continues to increase, 2012 annual average daily traffics are 31800, and the quantity that causes bridge expanssion joint to be changed of excessively travelling of the heavy overloaded vehicle more than 60% increases year by year.The main means that shrinkage joint construction is at present adopted are that half range construction half range is open to traffic, it is long to change the shrinkage joint construction road occupying time under the situation of this kind situation, causing stone peace speedway traffic congestion phenomenon happens occasionally, the bridge administrative staff in the road administration team member of the policeman of high speed Traffic Warden Subteam, road administration group and maintenance work area need the job site for this reason, command the vehicle that relieves traffic congestion.Sometimes, because of vehicle necking down section no thoroughfare herein, vehicle is crowded mutually, cause the vehicle crew to damage to cause injury harmful accident, bring huge pressure to traffic administration, grievous injury efficient, the straightway image of speedway, brought very big negative effect to society.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, mat formation fast, can satisfy vehicle current shrinkage joint under the construction state special-purpose fast-assembling road slab of constructing.
Overall technology design of the present utility model is:
The shrinkage joint special-purpose fast-assembling road slab of constructing comprises straddle mounting in the both sides, shrinkage joint and is the panel of domes, the liner plate that is fixed in panel inner surface and arranges in the same way with domes.
Concrete technical conceive of the present utility model also has:
Be the structural strength of assurance liner plate, and then guarantee that the structural strength of road slab, optimized technical scheme are, described liner plate adopts spring steel for making material.
Be the needs of the structural strength that further satisfies road slab, optimized technical scheme is that liner plate is at least two that arrange along the domes cocurrent and parallel.
Be to realize the tight fit of liner plate and panel, and then the work of assurance is reliable, optimized technical scheme is that described liner plate welds with the panel inner surface employing, bolted a kind of or its combination.
Can use by combination paving on the wide cut road surface for satisfying road slab, optimized technical scheme is that the described liner plate outside extends the outside shirt rim that forms of panel 1 one sides respectively.So in use, itself and the road slab that does not have a shirt rim structure can be overlapped at interval and form continuous structure, complete with the current and road slab structure that satisfies oversize vehicle.
Be difficult for realizing that at liner plate and panel under the situation of welding, optimized technical scheme is that described liner plate and panel inner surface adopt the dormant bolt secure fit.Guaranteeing to satisfy passing through smoothly of vehicle under the smooth situation of panel surface like this.
For the load that panel is born can be transmitted to the road surface, optimized technical scheme is that described panel two ends soffit is provided with horizontal cushion block.
For satisfying the fixing of panel, to realize stablizing under the road slab duty, optimized technical scheme is that the panel two ends offer installing hole.Available fixed component is fixed in the road surface by installing hole with road slab so when needed.
The obtained technological progress of the utility model is:
1, simple, the making and easy for installation of overall structure of the present utility model;
2, because the whole domes that adopt, and in be lined with the liner plate of spring steel quality, make road slab overall construction intensity height, can satisfy the current of large-tonnage vehicle, through experiment, under the construction state, repeatedly use and can satisfy vehicle pass-through and road slab is indeformable;
3, owing to offer installing hole at the road slab two ends, road slab can be fixed in the road surface easily, guarantee the stability of road slab under the use state.
4, the structure design of horizontal cushion block, the load that can effectively road slab be born is transmitted to the road surface, has guaranteed the application life of road slab.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Fig. 3 is the structural representation of another kind of road slab.
Reference numeral in the accompanying drawing is as follows:
1, panel; 2, liner plate; 3, installing hole; 4, horizontal cushion block.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further; but conduct is not to restriction of the present utility model; protection domain of the present utility model is as the criterion with the content of claim record; any equivalence techniques means of making according to manual are replaced, and all do not break away from protection domain of the present utility model.
The overall technology of present embodiment structure as shown, comprising straddle mounting in the both sides, shrinkage joint and be the panel 1 of domes, the liner plate 2 that is fixed in panel 1 inner surface and arranges in the same way with domes.
Described liner plate 2 adopts spring steel for making material.
Liner plate 2 is two that arrange along the domes cocurrent and parallel.
Be to realize the tight fit of liner plate and panel, and then the work of assurance is reliable, optimized technical scheme is that described liner plate 2 adopts with panel 1 inner surface and welds, bolted a kind of or its combination.
Liner plate 2 outsides extend the outside shirt rim that forms of panel 1 one sides respectively.During use, itself and the road slab that does not have a shirt rim structure can be overlapped at interval and form continuous structure, complete with the current and road slab structure that satisfies oversize vehicle.
Described liner plate 2 adopts the dormant bolt secure fit with panel 1 inner surface.
Described panel 1 two ends soffit is provided with horizontal cushion block 4.
Panel 1 two ends offer installing hole 3.Available fixed component is fixed in the road surface by installing hole with road slab so when needed.
