Abstract

The utility model relates to a container with a T-shaped floor center sill. In order to solve the problem that the traditional floor center sill used in the container needs to be provided with a deep tenon port, and the end parts between the adjacent floors can be mutually extruded. The floor center sill of the utility model is composed of a left bottom side, a right bottom side, and a vertical side, wherein the cross sections of the three sides are in a T-shaped structure; a floor on one side of the joint of each longitudinal floor is overlapped on the left bottom side of the floor center sill; the floor on the other side is overlapped on the right bottom side of the floor center sill, and the vertical side of the floor center sill is inserted into the floor joint. The T-shaped floor center sill is made of very thin materials in the utility model, and thus, the deepness of the floor tenon is greatly decreased, and the influence of the tenon on the floor intensity is reduced. In addition, since the two adjacent floors are divided by the vertical surface of the 'T'-shaped floor center sill, the mutual compression between the end surfaces of the adjacent floors can be avoided when the floor is downwards concave, and thus, the damage ratio of the floor can be lowered, and the service life of the container floor is improved.

Description

A kind of freight container that adopts ⊥ type floor central sill

Technical field

The utility model relates to freight container, more particularly, relates to a kind of freight container that adopts ⊥ type floor central sill at floor splicing seams place.

Background technology

Freight container from 1956 since the U.S. at first brings into use, passed through 40 years of development.At present, freight container traffic is widely used in the whole world.Traditional goods general purpose container generally is made up of both walls, door end, front end, top board, floor and underframe.Floor wherein and underframe are formed the carrying structure of goods in the case jointly.As Fig. 1, Fig. 2 and shown in Figure 6, in traditional freight container, underframe is mainly by two bottom side beams 11,12 and form with bottom side beams some horizontal bottom cross beams 3 connected vertically longitudinally; On bottom cross beam, lay the laminated wood floor 2 of 28 millimeters thick then, and clench, can constitute existing certain intensity, have a loading plane of better planeness again by screw 4.

In use, ground or the cabin of depositing freight container have ponding, enter inside damage goods and wood covering for preventing sealing or aqueous vapor, require freight container to have the better seal function.But because the restriction of making apparatus and manufacture craft, floor wherein is spliced by polylith wood covering 2, has a splicing seams between adjacent two floors; Wherein, the splicing seams parallel with bottom cross beam is set on the bottom cross beam, and realizes sealing by the method for playing glue between bottom cross beam and floor; But in common underframe, do not have the 3rd parallel with it beam between the bottom side beams 11,12, that is to say, the splicing seams of parallel floor with bottom side beams does not have beam to support; For addressing this problem, can on bottom cross beam 3, lay vertical with it, a lath that thickness is the 4-5 millimeter in traditional freight container usually as floor central sill 6, between floor central sill and wood covering, break sealant then and seal.Because the floor central sill has certain thickness of slab, for guaranteeing combining closely of wood covering and bottom cross beam surface, need to offer a small stair at the lower surface of wood covering end, be used to claim to offer tenon mouth 81.Wherein, the degree of depth of tenon mouth 81 is greater than the thickness of floor central sill, thus can cause the local reduction of ground plate thickness, the intensity on floor is produced tangible negative effect, a large number of experiments show that because of having offered tenon mouth 81, the floor at splicing seams place is easily damaged.

Another shortcoming of tradition chassis of container is exactly, when filling the turnover of goods or fork truck in the case, bottom cross beam 3 and wood covering 2 can produce concave deformation, makes extruding mutually between the floor of the splicing seams both sides parallel with bottom side beams, thereby causes the floor surface damage at splicing seams place easily.

The utility model content

Above-mentioned defective at prior art, thereby the utility model will solve and use traditional floor central sill need offer the problem that darker tenon mouth can cause the intensity on floor to weaken greatly in freight container, and the problem of damage is pushed, caused easily in the end that also will solve adjacent two floors when using traditional floor central sill mutually.

The technical scheme that its technical matters that solves the utility model adopts is: construct the freight container of a kind of ⊥ of employing type floor central sill, comprise underframe and the floor that is layered on the described underframe; Comprise in the described underframe that two foundation curb girders reach and described two foundation curb girders many foundation crossbeam connected vertically; Described floor is spliced by the polylith plate, and the longitudinal spliced seam between each floor has the floor central sill, and described floor central sill is supported on the described bottom cross beam; Wherein, described floor central sill is made up of left bottom surface, right bottom surface and vertical surface, and it is the structure of ⊥ type that described left bottom surface, right bottom surface and vertical surface constitute the cross section; The floor of described longitudinal spliced seam one side is overlapped on the left bottom surface of described floor central sill, and the floor of opposite side is overlapped on the right bottom surface of described floor central sill, and the vertical surface of described floor central sill then is inserted in the splicing seams of described floor.

In the utility model, be preferably integrative-structure between the left bottom surface of described floor central sill, right bottom surface and the vertical surface.And can to adopt thickness be that the thin materials such as steel, plastics or timber of 0.2-1.6mm are made.So, the degree of depth that can guarantee the floor tenon mouth of the longitudinal spliced seam both sides gap that is not more than 3mm and floor splicing seams is not more than 4mm.

In the utility model, extremely thin because of ⊥ type floor central sill, make that the degree of depth of floor mortise is less, can reduce the influence of mortise to floor intensity; In addition, because separated by the vertical surface of " ⊥ " type floor central sill between adjacent two floors, the mutual extrusion in the time of can avoiding the floor recessed between the adjacent floor, thus can reduce the damage rate on floor, improve the service life of container floor.
