Abstract
The present invention discloses one kind of no-ring current reinforced truss for double-block sleeper and its production process. The reinforced truss consists of two top main bars and four bottom main bars welded together, as well as end connecting bars, specially shaped connecting bars, S-shaped bars and locating round bars. The reinforced truss has low cost, firm structure and special structural treatment to eliminate the influence of the mutual inductance between the steel bars and the track circuit on the signal transmission length in ballastless track circuit.
Description
Technical field
The present invention relates to double-block type sleeper, especially relate to a kind of no-circulating reinforced truss for double-block sleeper and production method.
Background technology
Double-block type sleeper is to be embedded in the important structure part that is used for fixing fastener, rail and transmission train load in the ballastless track concrete road bed board, the accuracy of gauge when its high-precision manufacturing requirement can guarantee to lay a railway track, the truss bars that exposes can guarantee that the reliability that is tightly linked with the railway roadbed board concrete, non-prestressed structure design can reduce STRESS VARIATION complicated in the railway roadbed and avoid the generation of concrete cracks.
Germany Rehda-2000 rail system can not satisfy the requirement of Chinese track circuit transmission length in our track circuit parameter testing, according to the track circuit transmission principle double-block type sleeper bar construction is analyzed, should eliminate and reduce the influence of electric current mutual inductance in the circuit transmission, to increase the transmission length of track circuit.
Summary of the invention
The purpose of this invention is to provide a kind of influence that reduces electric current mutual inductance in the circuit transmission, strengthen the no-circulating reinforced truss for double-block sleeper of the transmission length of track circuit.
Another object of the present invention provides a kind of no-circulating reinforced truss for double-block sleeper production method simple, that cost is low of constructing.
In order to reach above-mentioned first purpose, the present invention adopts following technical scheme: a kind of no-circulating reinforced truss for double-block sleeper, described steel bar girder is made of four main reinforcements of two main reinforcements in top and bottom surface, between the top of steel bar girder two main reinforcements and the outside, bottom surface two main reinforcements, be welded with respectively and be oblique S shape reinforcing bar, the inboard main reinforcement in truss bottom surface is connected with top two reinforcing bars by deformed bar respectively, is welded with the reinforcing bar that is the ∏ type in the deformed bar left and right sides.
In order to reach above-mentioned second purpose, the present invention adopts following technical scheme: the welding production method of no-circulating reinforced truss for double-block sleeper is:
(1), four longitudinal screw reinforcing bar welding in bottom surface;
(2), two longitudinal screw reinforcing bar welding in top;
(3), by vertical termination dowel four longitudinal reinforcements of top two longitudinal reinforcements and bottom surface are welded;
(4), between the inboard longitudinal reinforcement truss of top two longitudinal reinforcements and bottom surface, weld deformed bar (b);
(5), in compiling the pallet frock, welding is oblique S shape reinforcing bar respectively between steel bar girder top two main reinforcements and the outside, bottom surface two main reinforcements, this S shape bar one-time moulding, this S shape reinforcing bar is connected with indented bars with the electric welding welding, and adds to weld and locate round steel temporarily.
Because the steel bar girder of double-block type sleeper has said structure, its main steel bar stress truss is below track, can not form current loop within the specific limits, promptly constitute no circulation steel bar girder, steel bar girder of the present invention adopts the acyclic muscle special construction of banising, in the time of can satisfying the railway roadbed leak resistance and be 3 Europe, transmission range reaches 1800M, truss bars therefore of the present invention adopts acyclic special structure treatment of banising muscle can eliminate the influence of the mutual inductance of reinforcing bar and the generation of track circuit electric current to no slag track circuit transmission length, its technology is a domestic initiation, and the special tectonic of S type truss arrangement of reinforcement is not seen use at home.The present invention can satisfy the requirement of China's track circuit transmission range.In addition, the construction of the production method of steel bar girder of the present invention is simple, and activity time is short, material is saved, and cost is low.

The specific embodiment
The structure of a kind of no-circulating reinforced truss for double-block sleeper of the present invention such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, described steel bar girder 1 is made of four main reinforcements of two main reinforcements in top and bottom surface, between the top of steel bar girder 1 two main reinforcements and the outside, bottom surface two main reinforcements, be welded with respectively and be oblique S shape reinforcing bar a, the inboard main reinforcement in truss bottom surface is connected with top two reinforcing bars by deformed bar b respectively, is welded with the reinforcing bar c that is the ∏ type in the deformed bar left and right sides.2 is concrete block, and its welding sequence of the production method of this truss is:
(1), four longitudinal screw reinforcing bar welding in bottom surface;
(2), two longitudinal screw reinforcing bar welding in top;
(3), by vertical termination dowel four longitudinal reinforcements of top two longitudinal reinforcements and bottom surface are welded;
(4), welding deformed bar b between top two longitudinal reinforcements and bottom surface four longitudinal reinforcement truss;
(5), in compiling the pallet frock, welding is oblique S shape reinforcing bar a respectively between the top of steel bar girder 1 two main reinforcements and the outside, bottom surface two main reinforcements, this S shape bar one-time moulding, this S shape reinforcing bar are connected with indented bars with the electric welding welding, and add the interim location of weldering round steel.
In order to guarantee in the steel bar girder that reinforcement location and bond pad locations are accurately and reduce the thermal stresses distortion that reinforcing bar causes because of welding, design is also made the specific welding assambly platform, with steel plate and the reinforced frame truss frock pedestal that is welded, its table top 800mm, table top is provided with fixedly longitudinal reinforcement and S type reinforcing bar position and fastening devices.The longitudinal reinforcement location: compile the spacing of pressing double-block type sleeper reinforcement drawing longitudinal reinforcement on pallet longitudinal register angle steel two right-angle sides in welding, quantity is carved into wide 15mm, and the sulculus of dark 6mm vertically falls in the groove so that location during welding.Pendulum, welding steel muscle order: bottom surface longitudinal reinforcement-top longitudinal reinforcement-vertically termination dowel-truss connects round bar.
The welding of double-block type sleeper steel bar girder: in special volume pallet frock, carry out the welding of steel bar girder, tiltedly S shape bar one-time moulding, and it is firm between the indented bars with the electric welding group, and add the interim location of weldering round steel on request, electric current should not be excessive to avoid damaging main muscle during welding, after the welding electric welding scum silica frost is knocked out, the steel bar girder after having welded must carry out the appearance and size inspection.Mutual dislocation between indented bars spacing and indented bars, error are measured with invar tape at ± 1mm, and tiltedly S muscle site error is at ± 3mm, and the whole warpage error in welding back adopts Steel Ruler to measure at ± 2mm.Tiltedly the S muscle is to finish by following steps: prepare, rule, try curved.
