Description

Overload heat-insulating bottom plate of whole-vehicle-level test cabin Technical Field The utility model belongs to the field of test cabins, and particularly relates to an overload heat-insulating bottom plate of a whole-vehicle-level test cabin. Background Environmental test cabins such as a high-low temperature damp-heat test cabin, a constant temperature and constant humidity test cabin and a cold and hot impact test cabin become an indispensable tool for improving the quality of products and improving the production process. In these test cabins, the heavy load-bearing heat-insulating bottom plate is used as an important component of the test cabin, and the heavy load-bearing heat-insulating bottom plate is required to bear concentrated loads generated by large test pieces, personnel walking, vehicle running and the like in the test cabin, and also has good heat-insulating performance so as to ensure the stability and uniformity of the temperature in the test cabin. Therefore, the design of the heavy load bearing heat insulating bottom plate directly influences the accuracy and reliability of the test result. Disclosure of utility model The utility model aims to provide an overload heat-insulating bottom plate of a whole vehicle-level test cabin. The utility model is realized according to the following technical scheme. The utility model provides an overload heat preservation bottom plate of whole car level test cabin, includes the polylith bottom plate, the bottom plate includes a plurality of I-steel supports of parallel arrangement on carbon steel plate and the carbon steel plate of bottom, and the welding of a plurality of parallel channel-section steel is in the same place between the I-steel support of arbitrary adjacent, still the array is provided with the flitch support between the I-steel support of arbitrary adjacent, I-steel support top is provided with the steel sheet, the flitch support with epoxy board and stainless steel checkered plate have been set gradually from down to the steel sheet top, the space intussuseption between carbon steel plate, I-steel support and the epoxy board is filled with polyurethane foaming agent, the I-steel support outside of the outermost both sides of a plurality of I-steel supports sets up the connection channel-section steel that is used for the fixing.
