Description
Technical field
The invention belongs to logistics equipment field, is related to a kind of complete fabricated no crossbeam 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, essentially added using three stackings on longeron+crossbeam+floor
Structure, between total height reaches 250-300mm, and connected between floor unit, between floor and crossbeam using welding manner.
Existing bottom plate is formed by stacking by longitudinal and transverse beam, three layers of floor, total height >=250mm, and floor and crossbeam, floor
It is welding manner connection between unit.Bottom plate is that three stackings add, and deadweight is larger and vehicle center of gravity raises；Floor unit is guarantee
Water proofing property, it is extremely inefficient more using whole full welds, large-scale automatic welding equipment need to be put into, the strength of materials is had a great influence, simultaneously
Slab element is that adaptation is welded to each other and can not be thinned with beam welding demand, section bar thickness, and it is further to limit light weight effect
Lifting.
The content of the invention
It is an object of the invention to provide a kind of full assembled of aluminium alloy without crossbeam base arrangement, bottom plate is by longeron+floor
（It is longitudinal spliced）Two layers are formed by stacking, and for total height between 180-230mm, center of gravity reduces 70mm；Between floor unit and floor with
All it is connected by screw bolts between longeron, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of full assembled of aluminium alloy is without crossbeam base arrangement, including longeron, floor unit, T-bolt, gib head pressing plate and angular
Connector, directly laying is designed with floor unit along longitudinal spliced floor unit, described floor unit one end on the longeron
End flange structure, coordinate with the floor unit end T-slot of another unit end set, floor unit end T-slot passes through
The T-bolt and it is connected in the Angle connection part of the longeron outside of belly and is connected with longeron, passes through hook between each two Angle connection part
Head pressing plate and T-bolt are connected with longeron top airfoil.
As the further scheme of the present invention：Floor unit end T-slot compresses floor unit end flange, leads to
Cross T-bolt to be connected with longeron, piece together a complete split T-slot, split T-slot passes through T-bolt and the longeron
Connection.
As the further scheme of the present invention：The Angle connection part is fixed on longeron by angle-shaped piece connecting bolt.
As the further scheme of the present invention：The T-bolt connects increase waterproof knot in mosaic after two floor units
Structure and waterproof gluing.
Compared with prior art, the beneficial effects of the invention are as follows：By the way that three stackings of former " longeron+crossbeam+floor " are added
Structure is changed to two layers of overlaying structure of " longeron+floor ", eliminates crossbeam, weight reduces more than 20% on year-on-year basis, and passes through floor
The T-slot structure of unit mosaic, the fabricated construction that floor and longeron beam connected mode are connected by screw bolts, without input
Soldering cramping apparatus and equipment, reduce effect on environment, improving productivity more than 20%.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1~5, in the embodiment of the present invention, a kind of full assembled of aluminium alloy is without crossbeam base arrangement, including longeron
1st, floor unit 2, T-bolt 6, gib head pressing plate 7 and Angle connection part 11, directly laying is along longitudinal spliced on the longeron 1
Floor unit 2, strength and stiffness demand when floor unit 2 has taken into full account carrying in design；The floor unit 2 one
End is designed with the structure of floor unit end flange 5, can coordinate with the floor unit end T-slot 3 of another unit end set, ground
Slab element end T-slot 3 compresses floor unit end flange 5, is connected by T-bolt 6 with longeron 1, piece together one it is complete
Whole split T-slot 9, split T-slot 9 are connected by T-bolt 6 with the longeron 1.
During assembling, every several floor units 2, floor unit end T-slot 3 is by the T-bolt 6 and is connected in vertical
The Angle connection part 11 of the outside of belly of beam 1 is connected with longeron 1, passes through gib head pressing plate 7 and T-bolt between each two Angle connection part 11
6 are connected with the top airfoil of longeron 1；The Angle connection part 13 is fixed on longeron 1 by angle-shaped piece connecting bolt 14.
After the longeron 1 is connected with floor unit 2, you can limit the movement of its Z-direction, ensure that its X is tight to split.
