Description
Technical field
The utility model relates to box car technical field, particularly relates to a kind of box car composite floor board.
Background technology
Box car has side wall, headwall, floor and roof, and on side wall, have the railway truck of slide and ventipane, in order to load and transport the valuable goods with being afraid of to expose to the sun and rain, along with the quick propelling of China's industrialization and urbanization, ecommerce is flourish, tremendous influence is created to the consumption habit of people, facilitates the develop rapidly of China Logistics industry.Internet+electric business+quick railway transportation becomes a new shipping development branch, safety, fast, efficiently, the railway transportation of environmental protection can better adapt to modern logistics development demand, the research and development of 160km/h box car will be the main vehicles of answering this development of demand, in addition on the one hand along with the development of modern logistics, also heat insulation to the in-built product of box car, impact resistance, wear-resisting antiskid, environmental protection and the performance such as recyclable are had higher requirement, , existing floor mainly contains steel floor and bamboo laminated board two class, although the strength and stiffness requirement that steel floor can meet, but fortunately there is not potential safety hazard in handling goods or goods transport process in antiskid capability, bamboo laminated board has certain antiskid capability, and lighter weight, but its insufficient strength, easily make moist and go mouldy, and then cause rotten, mechanical property reduces, and easily occurs fracture and interlaminar separation, there is potential safety hazard in cargo handing and transportation, the safety of transporting cargo is threatened, and threat traffic safety, simultaneously because the heat-insulating property of steel floor and bamboo laminated board is all poor, the growth requirement of current box car can not be met.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of box car composite floor board, unit composite panel is completely spread in existing box car chassis top surface, mortise-tenon joint or overlap joint between unit composite panel, and unit composite panel adopts glass fiber reinforced polyurethane composite material, meet hardness and shock resistance requirement, avoid potential safety hazard, guarantee the safety of transporting cargo, can also heat-insulating property be improved, meet box car growth requirement.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of box car composite floor board, comprises and is laid on box car underframe on the surface and the unit composite panel uniform along box car length over end sills direction, sealing docking between described adjacent cells composite panel.
Described unit composite panel is fixedly connected with the stringer of underframe by means of countersunk-heat bolt.
Described unit composite panel is glass fiber reinforced polyurethane composite material.
Described adjacent cells composite panel contact surface adopts mortise-tenon joint, and unit composite panel one side is tenon, and an other side is tongue-and-groove.
Bridging arrangement is adopted to connect between described adjacent cells composite panel.
Described unit composite panel upper surface applies polyurethane wear resistant coating
Adopt the beneficial effect that produces of technique scheme to be: by the stringer that the unit composite panel of glass fiber reinforced polyurethane composite material is completely layered on underframe as floor, give full play to the weather-proof of glass fiber reinforced polyurethane composite material and anti-fatigue performance, the mechanical property that floor is stable can be ensured in Long-Time Service process, simultaneously owing to adopting the mode of mortise-tenon joint or overlap joint to be tightly connected between adjacent cells composite panel, floor upper surface and lower surface are without directly through straight joint, improve protection against the tide and the heat-insulating property on floor, in addition on the one hand, unit composite panel upper surface of the present utility model applies polyurethane wear resistant coating, there is certain anti-skidding and wear resisting property, for steel floor and bamboo laminated board, longer service life, the operating needs of box car can be met.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model discloses a kind of box car composite floor board, comprise and be laid on box car underframe on the surface, and the unit composite panel 1 uniform along box car length over end sills direction, described adjacent cells composite panel 1 contact surface adopts mortise-tenon joint (see accompanying drawing 1-3), unit composite panel one side is tenon, an other side is tongue-and-groove, described unit composite panel is fixedly connected with the stringer 3 of underframe by means of countersunk-heat bolt, through hole offered by unit composite panel, in installation process, unit composite panel is fixed on stringer by direct use flathead screw, described unit composite panel 1 is glass fiber reinforced polyurethane composite material, it is indeformable that this kind of composite material has Long-Time Service, good stability of the dimension, there is excellent flame retardance, use safety, the feature of good weatherability, can ensure that a repair in shop phase is not changed, improve stability in use, reduce maintenance cost, owing to needing to use fork truck turnover in box car loading process, and need in box car inside turn, simultaneously in order to the wearing and tearing of prevention unit composite panel, unit composite panel upper surface applies polyurethane wear resistant coating, the service life of extension unit composite panel.
The unit composite panel used in the utility model uses the process of pultrusion and reaction foaming to make, simultaneously in order to two module unit composite panels sealings are embedding and, relative joinery and its construction (see accompanying drawing 1) be set respectively in substrate both sides or adopt bridging arrangement (see accompanying drawing 4), completing when mounted and splice.
In concrete installation process, first according to box car size pay unit composite panel, the unit composite panel both sides produced pre-set the joinery and its construction extruded, then direct unit composite panel of mating formation on box car underframe, unit composite panel is connected with the stringer on underframe by means of flathead screw, adjacent cells composite panel guarantee tenon and tongue-and-groove embedding and put in place, also bridging arrangement can be adopted to connect (see accompanying drawing 4-6), be paved with at the bottom of car, its by the stringer that the unit composite panel of glass fiber reinforced polyurethane composite material is completely layered on underframe as floor, give full play to the weather-proof of glass fiber reinforced polyurethane composite material and anti-fatigue performance, the mechanical property that floor is stable can be ensured in Long-Time Service process, simultaneously owing to adopting the mode of mortise-tenon joint or overlap joint to be tightly connected between adjacent cells composite panel, floor upper surface and lower surface are without directly through straight joint, improve protection against the tide and the heat-insulating property on floor, in addition on the one hand, unit composite panel upper surface of the present utility model applies polyurethane wear resistant coating, there is certain anti-skidding and wear resisting property, for steel floor and bamboo laminated board, longer service life, its density is 0.7-0.9g/cm
3, the operating needs of box car can be met.
