Description
Technical field
The invention belongs to logistics equipment field, is related to a kind of complete fabricated compartment bottom plate structure thereof.
Background technology
Floor pan assembly reaches 40%-50% part as weight accounting in compartment assembly, and steel are replaced using aluminum alloy materials
Making has obvious light weight effect.In in the market like product, longitudinal and transverse beam is due to for load part, to reduce welding knot
The loss of strength that structure is brought, thus it is more using the mechanical connection manner such as riveting, be spirally connected between the two pieces, but the connection of floor and crossbeam is general
It is logical to use welding manner, also it is welding manner split between floor unit.
The connection of existing floor and crossbeam uses welding manner more, is also welding manner split between floor unit.
Floor unit is extremely inefficient more using whole full welds to ensure water proofing property, large-scale automatic welding equipment need to be put into, to the strength of materials
Have a great influence, while floor unit is that adaptation is welded to each other and can not be thinned with beam welding demand, section bar thickness, is limited light
Quantification effect is further lifted.
The content of the invention
It is an object of the invention to provide a kind of full Fabricated Bottom Board structure of aluminium alloy, solderless is used between all parts
Connect, fabricated construction connection, improve production efficiency up to more than 20%, reduce loss of strength, weight can reduce 10% on year-on-year basis, with solution
The problem of being proposed in certainly above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of full Fabricated Bottom Board structure of aluminium alloy, including longeron, I-shaped crossbeam, channel crossbar, middle floor, side floor list
Member, gib head pressing plate, T-bolt and angular transition part, the longeron are provided with some spaced apart channel crossbars and I-shaped
Shape crossbeam, the channel crossbar and I-shaped crossbeam bottom are provided with the side floor unit of repetition split, side floor unit one end
Coordinate provided with floor unit end flange structure, and with the T-shaped groove in floor unit end that the other end is provided with, piece together one it is complete
Whole split T-slot；The T-shaped groove in floor unit end is connected by T-bolt and angular transition part with the channel crossbar outside of belly
Connect, be connected by gib head pressing plate and T-bolt with I-shaped crossbeam top airfoil.
As the further scheme of the present invention：Connected between the channel crossbar and longeron by gusset, the I-shaped
Connected between shape crossbeam and longeron by I-beam Angle connection part.
As the further scheme of the present invention：The symmetrical arrangement of side floor unit.
As the further scheme of the present invention：The split T-slot passes through T-bolt and the channel crossbar and I-shaped
Crossbeam connects.
As the further scheme of the present invention：The angular transition part is fixed on channel crossbar by angle-shaped piece connecting bolt
On.
As the further scheme of the present invention：In T-bolt connection after floor and floor side floor unit, by
Mosaic increases flashing member and smears waterproof gluing.
Compared with prior art, the beneficial effects of the invention are as follows：By the T-slot structure of floor unit mosaic, by ground
Plate and crossbeam connected mode are by welding the fabricated construction for being changed to be spirally connected, and without putting into soldering cramping apparatus and equipment, reduce pair
Environment influences, improving productivity more than 20%, and due to the loss of strength without considering welding, therefore crossbeam, floor can be further
It is thinned, weight reduces more than 10% on year-on-year basis.
