Problems solved by technology
[0002] The caravan frame in the prior art is generally provided with a caravan frame. The caravan frame has three types: wooden keel, aluminum alloy keel, and aluminum plate without keel. Among them, the wooden keel has the problems of heavy weight and easy water absorption and aging. The aluminum alloy keel has the problem of easy conduction of heat and the formation of condensed water in the car, and the structure without keel has the disadvantage of insufficient strength and potential safety hazards

The invention discloses a broken bridge type heat insulation box plate, which comprises an inner plate layer, a middle layer and an outer plate layer which are sequentially arranged, the middle layer comprises a heat insulation plate and a broken bridge type keel structure located at the two ends of the heat insulation plate, the broken bridge type keel structure comprises a first keel profile, a second keel profile and a broken bridge connecting piece, the first keel profile is connected with the inner plate layer, the second keel profile is connected with the outer plate layer, and the broken bridge connecting piece is located between the first keel profile and the second keel profile; the first keel profile and the second keel profile are both of an integrated structure and comprise a U-shaped plate and a reinforcing plate, the U-shaped plate comprises a connecting plate and supporting plates located at the two ends of the connecting plate, a dovetail groove is formed in the middle of the side face, close to the connecting plate, of each reinforcing plate, and broken bridge grooves are formed in the two ends of the side face, away from the connecting plate, of each reinforcing plate. According to the broken bridge type heat insulation box plate of the structure, the box plate can effectively prevent condensate water from being generated, the service life is long, and meanwhile the broken bridge type heat insulation box plate has the advantages of being light in weight and high in strength.
Description
technical field [0001] The invention relates to the technical field of box panels for recreational vehicles, in particular to a bridge-breaking type heat-insulating box panel. Background technique [0002] The caravan frame in the prior art is generally provided with a caravan frame. The caravan frame has three types: wooden keel, aluminum alloy keel, and aluminum plate without keel. Among them, the wooden keel has the problems of heavy weight and easy water absorption and aging. The aluminum alloy keel has the problem of easy conduction of heat to form condensed water in the car, and the structure without keel has the disadvantage of insufficient strength and potential safety hazards. For this reason, it is necessary to develop a new type of box board for a caravan, so that the box board can effectively prevent the generation of condensed water, have a long service life, and have the advantages of light weight and high strength. Contents of the invention [0003] The obj...
