Problems solved by technology
[0002] The side plate and roof foam of the existing refrigerated container larger than 40 feet are divided into three sections of high-pressure foaming at the front, middle and rear. After foaming, the inner wall board and the inner roof board are lapped and connected, and the middle frame lining is used to connect the two high-pressure foams, and secondary foaming is performed. The process is cumbersome, there are many longitudinal lap seams and pull rivets, and the assembly is time-consuming. It is difficult to work together, and it is easy to cause unevenness at the longitudinal overlap between the inner wall panel and the inner roof panel, forming steps, and causing the cargo packaging bag to be scratched and scratched

Embodiment Construction
[0012] Stainless steel plates are selected and TIG welded to form an inner wall plate 1 and an inner roof plate with a longitudinal integral structure, and the TIG weld bead 2 is smooth. The front ends of the inner wall board 1 and the inner top board 14 are respectively connected with the respective front end linings 3 by pull rivets, the rear end of the inner wall board is inserted into the groove of the rear side heat insulating member 5, and the rear end of the inner roof board is connected with the back top lining 15 by pull rivets. One end of the rear roof lining 15 is connected with the rear end pull nail of the inner roof plate 14 , and the other end is inserted into the rear roof heat insulator 16 . The outer wall plate 7 is connected with the two middle frame corner columns 6 and the outer roof plate 13 and the two middle frame lintels 12 first by spot welding, and the two middle frame corner columns are connected with the upper side beam 10 and the lower side beam 11...

This invention relates to cooling container sideboard and top board total foaming process in the technique field of container. The inner wall board and top longitude board are integrated and are separately connected to the front underlay by riveter and the inner wall board back end is inserted to the back heat isolation groove and the inner top board back end is connected to the back top underlay riveter. The outer wallboard is connected to the two middle frame angle column and outer top board, wherein; the two angle columns are connected to the upper and down side beams. Then the high pressure total foaming are processed between the inner and outer sidewall boards and between the inner and outer top boards.
Description
technical field [0001] The invention relates to an integral foaming process for a side plate and a top plate of a refrigerated container larger than 40 feet, and belongs to the technical field of containers.
