Abstract
The invention relates to a rail bearing trough plate for a concrete sleeper die. Raised fixed rail shoulders are respectively arranged on two sides of a rail bearing trough plate body; positioning devices are arranged at two ends of the bottom of a body; the body takes a steel plate as a skeleton; the outside of the steel plate is wrapped with a plastic elastomer made of polyurethane or vulcanized rubber. Through the adoption of the invention, since the rail bearing trough plate adopts a plastic steel composite technology, the rail bearing trough plate has certain hardness and elasticity, and the purpose of conquering the unyielding with the yielding is achieved; in the tensioning process, the plastic steel rail bearing trough plate can shrink and release stress well, overcomes a counterforce, achieves a favorable protection effect on a product, reduces the rejection rate, improves the economic benefits, and has excellent abrasive resistance, favorable reset elasticity and weather resistance.
Description
Technical field
The present invention relates to a kind of concrete crosstie mould support rail frid.
Background technology
At present, producing the support rail frid in concrete crosstie mould, the support rail frid that particularly prestressed concrete pillow mould uses all adopts steel to make, before the demoulding, deformed bar is put and to be produced stress and shrink, the phenomenon that frequent appearance is fallen to take on by External Force Acting because of fixing track omoplate place, have a strong impact on product quality, gently then need artificial reparation, heavy then scrap; Meanwhile, reaction force is produced, except injuring sleeper omoplate place when pressure is put at the two ends of steel rail frid, also can produce support rail frid premature wear or displacement etc., have a strong impact on product size and presentation quality, need frequent Maintenance and Repair, produce the higher cost of repairs, and normal operation is produced in impact.
Summary of the invention
The object of this invention is to provide the problem that effectively can overcome and fall shoulder by External Force Acting, can overcome again and put the reaction force phenomenon produced in a process, guarantee a kind of concrete crosstie mould support rail frid of concrete crosstie rail support groove dimensional accuracy.
The technical scheme that the present invention takes is: a kind of concrete crosstie mould support rail frid, comprise body, the both sides of body have outstanding fixing track omoplate, and the two ends, bottom of body are provided with positioner, it is characterized in that body is using steel plate as skeleton, is enclosed with plastic elastomeric outside steel plate.
Adopt the present invention; because concrete crosstie mould support rail frid have employed plastic-steel complex technique; there is certain consistency and elasticity; defeat a force with a tenderness, putting in a process, plastic-steel support rail frid can well shrink release stress; the support rail frid overcoming complete steel is putting the reaction force phenomenon produced in a process; good protective effect is served to product, reduces percent defective, improve economic benefit.Also has splendid wearability, good Flexible Reset and weatherability.
Accompanying drawing explanation
Fig. 1 is the present invention's local schematic top plan view when vertically placing for concrete crosstie mould.
Fig. 2 be the present invention when vertically placing for concrete crosstie mould partial side cut open schematic diagram.
Fig. 3 is that the present invention cuts open and shows schematic diagram.
In figure, sequence number represents: body 1, positioner 2, fixing track omoplate 3, steel plate 4 and plastic elastomeric 5.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
With reference to Fig. 1, Fig. 2 and Fig. 3, this concrete crosstie mould support rail frid comprises body 1, the both sides of body 1 have outstanding fixing track omoplate 3, the two ends of the bottom of body 1 are provided with positioner 2, body 1, using steel plate 4 as skeleton, is enclosed with the plastic elastomeric 5 of polyurethane or vulcanized rubber outside steel plate 4.Wherein this concrete crosstie mould is with the thickness of support rail frid light plate 4 at 5 ~ 20mm, and positioner 2 can adopt on screw rod or nut-welding to steel plate 4 fixing; Cast molding or injection mo(u)lding can be adopted.
In above-mentioned; because concrete crosstie mould support rail frid have employed plastic-steel complex technique; there is certain consistency and elasticity; defeat a force with a tenderness, putting in a process, Novel plastic-steel support rail frid can well shrink release stress; overcome steel support rail frid and put the reaction force phenomenon produced in a process; good protective effect is served to product, reduces percent defective, improve economic benefit.Also has splendid wearability, good Flexible Reset and weatherability.
