It is apparent that the implementation of the embodiments of the utility model is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the utility model, however, the utility model is capable of other embodiments in addition to those detailed.
The utility model provides a container used for a floor center sill. The container includes a base frame 110, side walls, end walls, and a top wall. The chassis 110, the side walls, the end walls, and the top wall constitute a generally rectangular parallelepiped structure.
As shown in fig. 1 and 2, the underframe 110 includes a bottom cross member 111, a bottom end member (not shown), a bottom side member (not shown), a floor 112, and a floor center member 114. The bottom end beam and the bottom side beam form a closed rectangular structure. The bottom cross member 111 is connected to the bottom side member.
The floor 112 is multi-piece (e.g., 6). The product of the length and width dimensions of each floor panel 112 is approximately 1.22mx 2.44m. A plurality of floor panels 112 are laid on the top surface of the bottom cross member 111 for carrying cargo within the container.
Preferably, as shown in FIG. 1, six floors 112 form a two-row, three-column configuration. Wherein, along the length direction (left and right direction of fig. 1) of the bottom frame 110, three columns of the floor boards 112 are arranged in sequence. The two rows of floor boards 112 are arranged in order along the width direction of the base frame 110 (the up-down direction in fig. 1). Adjacent floor panels 112 may be spaced apart. It will be appreciated that in embodiments not shown, adjacent floor panels may also be spliced. A greater number of floors may also be provided in sequence along the length of the underframe. A greater number of floors may also be provided in sequence along the width of the underframe.
Referring to fig. 2, the lower surface of the floor panel 112 forms a step structure. The step structure forms a gap in the floor 112. The notches are located at opposite ends of the adjacent floor panels 112 in the width direction of the base frame 110. The gap extends through the floor 112 along the length of the chassis 110. Thus, the notches of the adjacent floor panels 112 constitute receiving grooves 113 in the width direction of the base frame 110. The receiving groove 113 has a downward opening.
Preferably, the receiving groove 113 has a cross-sectional structure (the cross-sectional plane is substantially perpendicular to the lengthwise direction of the bottom chassis 110) configured as a substantially rectangular structure. Thereby, the processing of the floor 112 is facilitated.
The floor center sill 114 is constructed in a long strip structure. The floor center sill 114 is disposed along a length direction of the base frame 110, and has a structure of a cross section (the cross section is substantially perpendicular to the length direction of the base frame 110) configured as a rectangular structure. The area of the rectangular structure is slightly smaller than the area of the cross section of the receiving groove 113.
As shown in fig. 2, the floor center sill 114 is lapped to the bottom cross member 111. Preferably, the floor center sill 114 may be glued to the top surface of the bottom cross member 111. Thereby, the connection between the floor center sill 114 and the bottom cross member 111 is secured. In addition, the glue bond facilitates the installation of the floor center sill 114.
The floor center sill 114 is positioned within the receiving groove 113. In this way, the floor center sill 114 supports the adjacent floor panels 112 in the width direction of the base frame 110.
Preferably, the receiving groove 113 is located at a substantially middle position of the bottom chassis 110 in a width direction of the bottom chassis 110. Thus, the floor center sill 114 is located at a substantially middle position of the underframe 110 in the width direction of the underframe 110, and the structure of the underframe 110 is simple.
Preferably, the glue is applied to the surface of the floor center sill 114 facing the floor 112. Thus, the floor center sill 114 is adhered to the receiving groove 113 by glue. Thereby, the connection between the floor center sill 114 and the floor 112 is secured. In addition, the adhesive bonding method facilitates the installation of the floor 112.
The floor center sill 114 is constructed as a continuous fiber reinforced thermoplastic composite. Thus, the floor center sill 114 has high strength, high corrosion resistance, high toughness and high impact resistance. Thereby increasing the service life of the floor center sill 114 and thus the service life of the floor 112.
In the present embodiment, the floor center sill 114 supports the adjacent floor panels 112 in the width direction of the base frame 110. In this way, the floor center sill 114 may cushion the load between the floor and the bottom cross member, reducing wear on the floor 112. The floor center sill 114 is constructed as a continuous fiber reinforced thermoplastic composite material, and the corrosion resistance of the floor center sill 114 is strong, so that the service life of the floor center sill 114 can be prolonged, and the service life of the floor 112 can be further prolonged.
Preferably, the floor center sill 114 is constructed as a continuous fiber reinforced thermoplastic composite unidirectional prepreg tape. Thereby facilitating the material selection of the floor center sill 114.
The reinforcing fibers of the continuous fiber reinforced thermoplastic composite material constituting the floor center sill 114 include at least one of continuous glass fibers, continuous carbon fibers, and continuous aramid fibers. Therefore, the selection of the reinforced material is convenient.
The constituent floor center sills 114 are constructed as continuous fiber reinforced thermoplastic composite pieces. Thus, the floor center sill 114 can be directly installed without surface corrosion prevention treatment such as sanding, primer spraying, intermediate paint spraying and the like during installation, and the installation time is short. In addition, the floor center sill 114 is light in weight and convenient to install.
The matrix of the continuous fiber reinforced thermoplastic composite material constituting the floor center sill 114 includes at least one of PP (Polypropylene), PE (Polyethylene), PA6(Polyamide 6, nylon 6), PET (Polyethylene terephthalate), and PPs (Polyphenylene sulfide). Thus, the selection of the matrix is convenient.
Preferably, the floor center sill 114 is constructed in a multi-layered structure. The multilayer structure is arranged in order in the height direction of the chassis (up-down direction in fig. 2), and the extending directions of the unidirectional prepreg tapes of adjacent layers intersect (for example, the extending directions of the unidirectional prepreg tapes of adjacent layers are 90 °). In this way, the strength of the floor center sill 114 can be further enhanced.
The floor center sill 114 may be formed by a hot press composite process. And then cut to the desired size.
Preferably, the thickness dimension of the floor center sill 114 in the height direction of the base frame 110 ranges from 3mm to 6 mm. Thus, the thickness of the floor center sill 114 can be reduced as much as possible while ensuring the strength of the floor center sill 114. It is further preferred that the thickness dimension of the floor center sill 114 is 4 + -0.3 mm.
Preferably, the width dimension of the floor center sill 114 in the width direction of the underframe 110 is in the range of 40mm-80 mm. Thus, the width of the floor center sill 114 can be reduced as much as possible while ensuring the strength of the floor center sill 114. Further preferably, the width dimension of the floor center sill 114 is 50 ± 2 mm.
Preferably, the lengthwise dimension of the floor center sill 114 along the length of the underframe 110 ranges from 5800mm to 8600 mm. Thus, the floor center sill 114 is adaptable to containers of different sizes.
The utility model also provides a container. The container includes the aforementioned floor center sill 114.
In this embodiment, the container includes the floor center sill 114 described above. The floor center sill 114 supports the adjacent floor panels 112 in the width direction of the base frame 110. In this way, the floor center sill 114 may cushion the load between the floor and the bottom cross member, reducing wear on the floor 112. The floor center sill 114 is constructed as a continuous fiber reinforced thermoplastic composite material, and the corrosion resistance of the floor center sill 114 is strong, so that the service life of the floor center sill 114 can be prolonged, and the service life of the floor 112 can be further prolonged.
