Abstract
The utility model relates to an RPC railway ballast trough plate of a railway steel truss girder. A highly reinforcing bar concrete slab of a steel truss girder bridge deck slab is large in self weight, the bridge deck slab can be cracked easily after being pulled, and thus maintaining is difficult. The RPC railway ballast trough plate is provided with an RPC railway ballast trough plate body which is formed by the way that branched blocks are orderly arrayed longitudinally and transversely. The railway ballast trough plate body is provided with longitudinal beam connecting preformed holes. Longitudinal stiffening ribs which are perpendicular to the railway ballast trough plate body and transverse stiffening ribs are arranged at the bottom of the railway ballast trough plate body. A ballast blocking wall and a protecting wall which are vertically arranged in the longitudinal direction are arranged on the two transverse sides of the plate face of the railway ballast trough plate body respectively. According to the RPC railway ballast trough plate of the railway steel truss girder, full-bridge railway ballast trough plates are mutually independently arranged in a blocking mode according to each railway line, so that repairing and maintaining are convenient; longitudinal beams are arranged in a blocking mode according to transportation capability and hoisting construction control sizes, hence, the railway ballast trough plate is merely used as a structure for bearing bridge deck loads and does not participate in overall stress, and the structural stress is clear.
Description
Technical field
the utility model belongs to bridge construction technical field of buildings, is specifically related to a kind of rail iron trusses RPC railway ballast frid.
Background technology
Steel bridge has that span ability is large, suitability for industrialized manufacture, constructability, be easy to the feature of repairing, and is conventional scheme in big or middle span bridge design.Steel purlin is common structure in Longspan Bridge especially, is widely used in the structures such as large-span suspension bridge, cable stayed bridge, steel braced arch, steel truss girder.Traditional open bridge floors girder steel is because noise is large, it is tired easily to produce, track stability is not enough, should not use in High-speed Railway Bridges, on the bridge of steel purlin, railway ballast frid is set, and is designed to the form of tiny fragments of stone, coal, etc. bridge floor for this reason, problem that can efficient solution Cassia tora bridge floor.Railway ballast frid mainly contains the forms such as high armored concrete plate, Orthotropic Steel Bridge Deck+concrete pavement at present.
High armored concrete plate, from great, causes main truss steel using amount to increase; Easy to crack after bridge deck tension, after cracking, structure stress is complicated and uncontrollable, and maintenance difficult has reduced the durability of structure.The Steel Bridge Deck of Orthotropic Steel Bridge Deck+concrete pavement easily produces fatigue, and concrete pavement is easy to crack, maintenance difficult; Concrete pavement and the firm anticorrosion difficulty of bridge floor contact surface; Deadweight is large, main truss steel using amount is large.
RPC (RPC) material is a kind of novel high-strength material, adopts prefabrication, and properties of product are stable, in design, adopt after suitable safety factor, can guarantee not ftracture in normal use procedure, overall performance is good, can meet well functional performance and the durability of structure.Because intensity is high, physical dimension is little compared with conventional concrete railway ballast frid, has alleviated thus dead load, reduces main truss structure steel using amount.
Summary of the invention
The purpose of this utility model is to provide a kind of rail iron trusses RPC railway ballast frid from high, stressed clear and definite, the convenient for maintaining of heavy and light, intensity.
The technical scheme that the utility model adopts is:
A kind of rail iron trusses RPC railway ballast frid, is characterized in that:
The railway ballast frid body that is provided with RPC material, railway ballast frid body is made up of piecemeal, and vertical, horizontal is neatly arranged and is formed railway ballast frid body;
On railway ballast frid body, be provided with longitudinal beam connected preformed hole, the position of longitudinal beam connected preformed hole is corresponding with the fixing peg on longeron, in order to railway ballast frid is fixed on to longeron;
Railway ballast frid body bottom is provided with longitudinal stiffener and the transverse stiffener perpendicular to railway ballast frid body, and longitudinal stiffener and transverse stiffener are orthogonal.
Railway ballast frid body upper face both lateral sides is respectively arranged with vertically longitudinal gear Zha Qiang and protecting wall, adopts the cast in situs of C50 concrete.
Described longitudinal beam connected preformed hole is arranged on the longitudinal stiffener place of railway ballast frid body.
The utlity model has following advantage:
Full-bridge railway ballast frid direction across bridge of the present utility model, by the separate piecemeal layout of carrying out of each railway line, is convenient to maintenance and maintenance; Vertical bridge, to carrying out piecemeal setting by the size of transport capacity and lifting construction control, make railway ballast frid only as bearing the structure of bridge floor load, and it is stressed not participate in entirety, and structure stress is clear and definite.And because piecemeal is arranged and prefabricated railway ballast frid, make to safeguard and change more for convenience, and minimum on railway transport capacity impact.Under regular service conditions, railway ballast frid does not ftracture, and makes the emphasis of waterproof concentrate on the longitudinal piecemeal seam crossing of railway ballast frid, is easy to solve waterproof problem, and structure durability is guaranteed.Because structure has alleviated deadweight, reduce the consumption of main truss steel, there is higher economy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-railway ballast frid body, 2-longitudinal stiffener, 3-longitudinal beam connected preformed hole, 4-transverse stiffener, 5-protecting wall, 6-keeps off Zha Qiang.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of rail iron trusses RPC railway ballast frid that the utility model relates to, be applicable to steel purlin structural bridge, referring to Fig. 1, it is provided with the railway ballast frid body 1 of RPC material, railway ballast frid body 1 is nonintegrated structure, be made up of piecemeal, vertical, horizontal is neatly arranged and is formed railway ballast frid body 1, forms railway deck, suitable bridge is to block length 2.5 m and 3m, direction across bridge is divided into 2 (double track railway, one, every line railways), wide 5.05m.Railway ballast frid body 1 direction across bridge, by the separate piecemeal layout of carrying out of each railway line, is convenient to maintenance and maintenance; Vertical bridge, to for alleviating lifting weight and convenient transportation, also carries out piecemeal layout.On railway ballast frid body 1, be provided with longitudinal beam connected preformed hole 3, the position of longitudinal beam connected preformed hole 3 is corresponding with the fixing peg on longeron, in order to railway ballast frid is fixed on to longeron.Railway ballast frid body 1 bottom is provided with the longitudinal stiffener 2 and transverse stiffener 4 perpendicular to railway ballast frid body 1, and longitudinal stiffener 2 is orthogonal with transverse stiffener 4.Longitudinal beam connected preformed hole 3 is arranged on longitudinal stiffener 2 places of railway ballast frid body 1.Railway ballast frid body 1 upper face both lateral sides is respectively arranged with vertically longitudinal gear tiny fragments of stone, coal, etc. wall 6 and protecting wall 5, adopts C50 concrete to build at the scene.
