For example, the sidewall of traditional box type semi-trailer box is to add interior exterior skin (steel plate or aluminium sheet) by skeleton structure to constitute side plate, side plate is riveted the formation sidewall each other, this constructional feature of sidewall makes that its thickness is big, deadweight more greatly, easy-maintaining not, and the envelope inner width is restricted, therefore, the sidewall of this skeleton structure market of gradually fading out.The box type semi-trailer box sidewall mainly adopts the side plate of chassis less construction at present, as adopting by the metal surface plate with multiplying plywood, plank, plastic flagstone or other wood-based plates etc. is the composite panel that sandwich was constituted, and the surface metal plate of this composite panel and central layer are bonding by lining cement.This composite panel makes the envelope better appearance because its surfaces externally and internally is all more smooth.
As shown in Figure 1 to Figure 3, adopting the compartment envelope sidewall of exoskeletal side plate vertically to be stitched together by some composite panels 10 usually constitutes, the coupling end of adjacent composite panel 10 connects by interconnecting piece 11, outer connector 12 and rivet 13, makes sidewall after the connection satisfy the strength and stiffness requirement of envelope.But there is following shortcoming in the connection structure of the exoskeletal side plate of existing envelope sidewall:
1, in order to make exoskeletal side plate connection structure satisfy the intensity of envelope, rigidity requirement, the cross-sectional plane of the interconnecting piece 11 of existing compartment envelope sidewall adopts the middle part to the projecting inward wave mode structure in railway carriage or compartment, like this, there is the step that protrudes in the envelope inside surface of side wall, be easy to generate between goods and the sidewall step when making cargo handing to wipe and bump even tighten, oppose side wall structure and goods all damage easily;
2, dwindle the inner width of envelope to the projecting inward side wall construction in railway carriage or compartment, reduced the efficient loading space of envelope.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of large-size box sidewall is provided, solves the above-mentioned defective that prior art exists.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of large-size box sidewall, comprise polylith exoskeletal side plate that splices mutually and the splicing construction that is connected two adjacent exoskeletal side plate splice ends, this splicing construction comprise be clipped in two adjacent exoskeletal side plate splice ends both sides be positioned at case interconnecting piece, be positioned at case outer outer connector and the rivet that is connected this inside and outside attaching parts and exoskeletal side plate splice ends, it is characterized in that: the lap cross-sectional plane of described interconnecting piece and described exoskeletal side plate splice ends is a bellows-shaped.
