Refrigerated railway car is mainly used in the long-distance transport of fresh and alive perishable freight, and the body construction of refrigerated railway car needs good heat preservation and insulation.Because the volume of refrigerated railway car, load carrying ability and side wall area are all comparatively large, so the heat-proof quality of side wall directly affects the integral heat insulation performance of refrigerated railway car.At present, be mainly filled with the heat insulation material of flame resistance polystyrene and polyurethane integral in the side wall of refrigerated railway car to foam two kinds of structures.
" the heat insulation material structure of flame resistance polystyrene ", between the inside and outside wall board of side wall, be namely filled with the heat insulation material of fritter flame resistance polystyrene, its structure is simple, easy to operate." polyurethane integral foaming structure ", filling between the inside and outside wall board of side wall by polyurethane foams, polyurethane foams foaming is enriched in each corner and is foamed as overall; Very close to each other and density is comparatively large between overall polyurethane foams and the inside and outside wall board of side wall, sealing property is better, and then makes the heat-proof quality of side wall better.
But there is following defect respectively in the heat insulation material of flame resistance polystyrene and the polyurethane integral two kinds of structures that foam:
(1) density of polystyrene material is less, thermal insulation is poor; Meanwhile, there is gap between the block heat insulation material of flame resistance polystyrene and the inside and outside wall board of side wall, easily form circulating air, and then the heat-proof quality of side wall can be reduced.Therefore, adopt the heat-proof quality of flame resistance polystyrene heat insulation material structure poor, and then reduce the macroeconomic performance of refrigerated railway car.
(2) because polyurethane foams has huge swelling force in foaming process, so in order to ensure the stable of side wall, need to be fixed outside the inside and outside wall board of side wall by tooling device.Area due to van cooler side wall is comparatively large and the inside and outside wall board of side wall is swaged plate, therefore the tooling device needed for side wall integral foam of van cooler is comparatively large, and not only complicated structure is expensive, and work-yard needed for tooling device is comparatively large, is not easy to people and uses.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of double thermal insulation composite sidewall for refrigerated railway car.The present invention takes full advantage of the advantage of heat insulation material and heat insulation foaming block, can reduce manufacturing expense on the basis ensureing better heat-proof quality, is convenient to people and uses, and is suitable for promoting.
For reaching above object, double thermal insulation composite sidewall for refrigerated railway car provided by the invention, comprise external wall and inside wall, external wall is fixedly connected with inside wall, and external wall comprises Side fascia, the inner side of Side fascia is provided with connecting framework, connecting framework comprise some connect bones, described external wall also comprises some tie-beams, tie-beam be connected bone one_to_one corresponding, one end that every root connects bone is fixed on Side fascia, and the other end is fixed on corresponding tie-beam; Be filled with heat insulation material between Side fascia and tie-beam, heat insulation material covers all connection bones, and the insulation surface of heat insulation material is concordant with tie-beam;
Described inside wall comprises at least 2 insulating units, and each insulating unit comprises interior panel and is positioned at the heat insulation foaming block inside it, and adjacent 2 insulating units are connected by the mode of overlap joint, and all overlap joint parts are all fixed on the tie-beam of external wall.
