Abstract
The utility model provides a wide seaming device of a plate-type ballastless track, aiming to solve the problems that the wide seaming device in the prior art is bad in waterproofness, and is labour consuming, time-consuming and high in cost while adjusting the longitudinally connected stress. The device includes a plurality of track slabs, the two vertical ends are step-shaped and the upper part of each slab is narrower than the lower part, the step-shaped horizontal planes of the track slab are provided with pre-embedded bolt sleeves, and cover plates are covered on the step-shaped horizontal planes at the opposite sides of the two adjacent track slabs, and water swellable sealing rods are arranged between the step-shaped horizontal planes and the lower end surfaces of the cover plates, threaded holes corresponding to the positions of the pre-embedded bolt sleeves are arranged in the cover plates, fixing bolts are penetrated through the threaded holes and the pre-embedded bolt sleeves, and urethane foams are arranged between the every two adjacent track slabs under the cover plates. The device provided, reasonable and reliable in design, facilitates the adjustment of the longitudinally connected stress due to season temperature difference to prevent the hidden troubles of tracks due to the arching of the track slabs; furthermore, the device improves the water proofing performance and performs sealing protection, therefore, the deice has the advantages of time-labor saving, convenient construction and low cost.
Description
Technical field
The utility model relates to wide jointing apparatus, is specially the wide jointing apparatus of a kind of plate-type slag-free orbit.
Background technology
In the plate-type slag-free orbit system, be example, form by reinforced concrete footing, CA mortar bed (the III template adopts self-compacting concrete), prefabricated road bed board, gapless rail etc. from bottom to top with CRTS II template formula.For globality and the ride comfort of keeping circuit enduringly, design is carried out the pre-stressed longitudinal couplet with the unit precast plate of railway roadbed.
Because the influence that changed by seasonal temperature; The pre-stressed longitudinal of paragraph of growing up joins railway roadbed and can produce bigger vertical extruding force; Special under the effect of summer high temperature, under the effect that longitudinal dilatation is exerted oneself, bed board occurs and encircle generally; Cause bed board to separate (gap occurring), have a strong impact on the ride comfort of traffic safety and circuit with the CA mortar bed.In this case, must carry out suitable adjustment to the vertical prestressing force that joins, and the gap that occurs is implemented the plugging filling maintenance.
For the ease of the vertically operation of connection, reserved the longitudinal slot of broad between road, the unit bed board, after the operation of the vertical couplet of enforcement, need thoroughly seal with cast-in-situ steel reinforced concrete, technical term is called wide joint treatment.
Wide joint treatment has two and mainly acts on, and the one, to indulging the couplet part and indulging couplet stress protection is provided, prevent to indulge the couplet part and become flexible and damage; The 2nd, wide seam scope is filled, prevent in the wide seam of rainwater intake duct bed board with the road bed board under, cause icing frost heave when running into cryogenic conditions, change and vertically join stress even the road bed board is lifted and influences the circuit ride comfort, cause the potential safety hazard of driving accident.
The wide seam construction that adopts at present when receiving the seasonal temperature variation, generally ftractures, intakes; Change when needing that artificial adjustment is vertical to join stress simultaneously at temperature; Need the concrete of longitudinal slot place filling is all chiseled; After readjusting vertical couplet stretcher; Again seal with steel concrete again, and the circuit that thermal stresses causes is arched upward and then causes that the phenomenon of bed board gap carries out the sealing filling and repairing.Every year at least twice, time-consuming and extremely uneconomical.
Summary of the invention
The utility model is time-consuming and problem that cost is high when solving that existing wide jointing apparatus water resistance difference and adjustment are vertical to join stress, provides a kind of plate-type slag-free orbit wide jointing apparatus.
The utility model is to adopt following technical scheme to realize: the wide jointing apparatus of plate-type slag-free orbit; Comprise vertical two ends be stepped and upper width less than some roads bed board of lower width; Be equipped with the pre-embedded bolt sleeve on the ladder horizontal plane of road bed board; And adjacent road bed board is stamped cover plate on the ladder horizontal plane of a side in opposite directions, and and the cover plate lower surface between be provided with the water-swellable sealing rod, have on the cover plate and the corresponding screwed hole in pre-embedded bolt sleeve position; Be installed with set bolt in screwed hole and the pre-embedded bolt sleeve, be provided with polyurethane foam plastics between the adjacent road bed board of under.During operation; Lay plate-type slag-free orbit road bed board according to design, perfusion CA mortar bed is implemented vertical the couplet under the suitable technique condition; The water-swellable sealing rod water-swellable sealing of under; The slit that anti-sealing bleeds between the adjacent road bed board is located, and polyurethane foam plastics seals longitudinal reinforcement and the vertical stretcher that joins simultaneously, further plays sealing function; When joining stress according to the seasonal variations adjusting is vertical, unclamp set bolt and take off cover plate, remove polyurethane foam plastics; The vertical stretcher that joins is adjusted, after the completion again the cast polyurethane foamed plastics will indulge and join reinforcing bar and stretcher sealing, cover cover plate; Tighten set bolt; Adjustment process is time saving and energy saving, can reuse simultaneously, provides cost savings in a large number.
The screwed hole place of cover plate upper end has counterbore, and the cover plate upper surface flushes with bed board upper surface, road, and this structure makes the bed board surfacing, and is more reasonable.
The utility model reasonable in design is reliable; Maintenance work after simplification construction and the operation; Realized that batch production is prefabricated, overcome the workload that cuts and pour into a mould wide joint concrete repeatedly, fundamentally solved the wide seam fluid concrete scene difficulty with maintenance of vibrating; Made things convenient for the vertical adjustment work that joins stress of the temperature difference in season especially, prevented that the railway roadbed plate arch from rising and cause circuit hidden danger to take place; Adopt horizontal bench and water-swellable sealing rod to cooperate and carry out waterproofing work, improved water resistance; Adopt polyurethane to carry out seal protection, have time saving and energy saving, easy construction and the low advantage of cost, be particularly useful for domestic CRTS II of applying and the wide joint treatment of researching and developing central III template formula ballastless track at present.
