Furthermore, a plurality of plug welding holes are formed in the lower cold-formed steel.
Further, installing support tip and middle part set up the strengthening rib that has the plug welding hole and through plug welding hole and along automobile body length direction side wall stand side plug welding be connected, upper portion cold-formed steel upper edge and lower part cold-formed steel lower limb respectively with along the openly welded connection of automobile body length direction's side wall stand, lower part cold-formed steel is through plug welding hole and along automobile body length direction's side wall lower floor window upper portion crossbeam plug welding be connected.
Furthermore, a plurality of through holes are formed in the upper cold-formed steel, and the side part of the aluminum alloy composite floor is lapped on the mounting support and is connected through rivets.
If adopt traditional crossbeam and ripple floor welding to combine the built-in transition floor structure of dress, not only the construction degree of difficulty is big, the cycle length, the structure is complicated, and the automobile body can appear overweight more, warp great, the unmatched problem of mode, is unfavorable for the synthetic assembly of vehicle and operation, the utility model discloses not only solve the overweight, the problem that the vehicle mode matches of double-deck stainless steel automobile body, reduce the construction degree of difficulty simultaneously, the modularization installation can promote work efficiency by a wide margin, composite floor and installing support can be under construction simultaneously respectively, and synthetic installation back floor region does not warp, need not to adjust and repair, can directly be as guest room floor, simple structure.
