Abstract
The utility model relates to an integral reinforced concrete surfacing board for the railway crossing, and is suitable for the railway level crossing. The utility model is characterized in that the integral reinforced concrete surfacing board comprises basically a concrete board body and reinforcements; the length of the concrete board body is 2. 5m-3. 5m; the width is 2. 9m-3. 1m, and the thickness is 0. 5m-0. 6m. The front and back ends of the concrete board body are provided with corresponding bearing slots; grooves whose width is 328mm with rectangular gears are symmetrically arranged at the upper surface of the concrete board body along the axial direction of the length; screw bolts for fixing steel rails are embedded in the grooves; the center-to-center space of the two grooves is matched with the space between of the steel rails. The paved railway crossing of the utility model has the advantages of low cost, long service life, small repairing amount, short installation time, smooth railway crossing surface, etc.
Description
Technical field
The utility model is the whole slab of the steel bar concrete of a kind of iron level crossing, is applicable to railway level-crossing.
Background technology
Level crossing form of structure commonly used is employing sleeper slab road junction, and this form of structure is to adopt the oil immersion sleeper under the rail, and sleeper upper berth steel bar concrete slab or stone are made flangeway with relayable rail.Mainly have following shortcoming: application life is short, and railway roadbed is yielding, and maintenance capacity is bigger, and cost is higher, and the set-up time is long, and pavement roughness is unfavorable for vehicle operating etc.
The rubber flooring road junction had been used at railway interests's part road junction afterwards.As the railway rubber wire paving plate that Zhejiang Province balcony railway rubber mat plate factory produces, the patent No. 02307382.9,02235929.x, 02235930.3, this form of structure mainly is to change the steel bar concrete slab in the way of road junction commonly used into rubber flooring.
This form road junction main feature is that maintenance capacity reduces relatively, but cost is too high, general 11000 yuan every meter.
Summary of the invention
The purpose of this utility model is in order to prolong road junction application life, to reduce the road junction maintenance, reduce the road junction cost, shorten the set-up time, guarantee the road junction evenness of road surface, the whole slab of the steel bar concrete of the level crossing that applicability is strong.
The whole slab of the steel bar concrete of level crossing, it is characterized in that: comprise being the concrete plate body of rectangle substantially and being embedded in reinforcing bar in the concrete, the length of concrete plate body is 2.5m-3.5m, width is 2.9m-3.1m, its thickness is 0.5m-0.6m, and its front and back end is provided with corresponding socket joint groove, and the axis direction along its length on the concrete plate body is arranged with the 328mm wide groove of both sides for the band rectangular teeth, groove is embedded with the fixedly bolt of rail, and the center distance of two grooves cooperates with the axis spacing of two rail.
| The utility model effect (8 meters wide road junctions) | Existing road junction commonly used |
| 1, application life is more than 10 | 1, general 5 |
| 2, reduce maintenance, maintenance-free in 10 | 2, general |
| 3, cost is low, about 1000 yuan every meter at | 3, general 2000 yuan every |
| 4, set-up time weak point, per 5 | 4, the general set-up time is more than 8 |
| 5, road junction evenness of road surface, indeformable, vehicle operating is steady | 5, behind the some months, the road surface occurs uneven, influences the operation of vehicle |

The specific embodiment
The whole slab of the steel bar concrete of level crossing, it is characterized in that: comprise being the concrete plate body 5 of rectangle substantially and being embedded in reinforcing bar 10 in the concrete, axis direction along its length on the concrete plate body is arranged with the 328mm wide groove 2 of both sides for the band rectangular teeth, groove is embedded with the fixedly bolt 4 of rail, the center distance of two grooves cooperates with the axis spacing of two rail, the length of concrete plate body is 2.5m-3.5m, width is 2.9m-3.1m, its thickness is 0.5m-0.6m, its front and back end is provided with corresponding socket joint groove 6, and the socket joint groove can adopt triangle, rectangle, various ways such as circular arc.
When making the steel bar concrete slab, must select smooth making place, guarantee its bottom surface levelness, be convenient to the road junction requirement that back railway ballast, gauge level reach the construction of railways standard is installed.Give in the steel bar concrete slab and stay groove width to get 328mm, curve is got 90 millimeters for following strand, generally is not more than this value.Main consider that the road junction uses rear rim groove place easy to wear, width increases, and is no more than 110 millimeters of the width of demand of technical standard.
The basis, road junction makes, and thick 200 millimeters with 37 lime earth, the compacting coefficient reaches 0.9, guarantees that road junction installation back sedimentation is no more than 14 millimeters.
Road junction erection stage and maintenance stage shorten as far as possible, to reduce the road and rail down time.Get all the material therefor utensil ready before general the installation, it is fixing that rail 1 usefulness fastener 9 and nut 8 is installed, and back-grouting adopts high strength rapid hardening concrete then, and all leave suspension hook 3 among flangeway 7. figure in the inboard of two rails, be used for handling install and use install after, redeck after the back-grouting.
