Abstract
A connecting device between a floor and a back frame of a container belongs to a technical field of containers, which comprises an aluminum connector, a back door saddle, a thermal insulator, a chock, and a support block. The utility model is characterized in that one end of the aluminum connector is welded with the floor, a clamper on another end thereof is embedded and connected with a clamping groove of the thermal insulator, an upper face of the aluminum connector is a plane or an inverse T-shaped platform (a curtain track can be arranged on a groove formed by the inverse T-shaped platform), and a low face thereof is provided with strengthen bars. The aluminum connector can connect the back door saddle and the floor skillfully, and the utility model has the advantages of simple and reasonable structure, easy production, non water leakage, non thermal conduction and better thermal insulation.
Description
Technical field
The utility model relates to refrigeration or the floor of thermal container and the connecting device between the after-frame, belongs to the container technology field.
Background technology
Existing refrigeration or thermal container doorsill structure as shown in Figure 3, are made up of back threshold, chock, thermal insulation barriers, fasten aluminium, tie bolt etc., and thermal insulation barriers, chock and fasten aluminium adopt tie bolt to be connected and fixed.Because adopt bolted connection, bolt passes heat-insulation layer and stretches out outside the case in case, form heat bridge, the freight container outside heat is imported in the case, influence the temperature in the case; Bolt makes bolt be easy to generate the slit on every side owing to often be subjected to the bump of cargo handing, and the exterior water and air of freight container will enter foaming layer, thereby influences the heat insulation effect of freight container.And bolts assemblies is loaded down with trivial details, time-consuming taking a lot of work.At above defective, for improving the production efficiency of freight container, cost-cutting guarantees refrigeration or thermal container waterproof, heat preservation and insulation simultaneously, and freight container is made enterprise and pressed for the connecting device of researching and developing between a kind of later-model floor and the after-frame.
Summary of the invention
The purpose of this utility model is to provide a kind of economical and practical refrigeration or the floor of thermal container and the connecting device between the after-frame by the improvement to existing refrigeration or thermal container doorsill structure.
The purpose of this utility model is achieved in that the connecting device between container floor and the after-frame, comprise fasten aluminium, back threshold, thermal insulation barriers, cushion block, it is characterized in that being provided with back-up block, fasten aluminium one end and floor welding, the other end is provided with the draw-in groove that is provided with on buckle and the thermal insulation barriers and inlays and be connected, be provided with sealant between fasten aluminium and the thermal insulation barriers, back-up block is arranged on the following of cushion block and the back threshold is welded to connect.
Described fasten aluminium is provided with concaveconvex structure.Described fasten aluminium is flat, and lower surface is provided with reinforced rib.Described fasten aluminium is a projective table type, and lower surface is provided with reinforced rib.Reinforced rib can be square groove or the support of " I " shape.Back-up block and inside and outside threshold are welded to connect, and cushion block is arranged on the back-up block, and fasten aluminium and thermal insulation barriers are played support and heat-blocking action.
The utility model is rational in infrastructure, simple, manufacture easily, thermal insulation barriers adopts draw-in groove to be connected with fasten aluminium, and adds sealant in all parts junctions, effectively prevent the phenomenon of leaking, seeping water between thermal insulation barriers and the fasten aluminium, guaranteed the water-proof, heat-insulating, heat-preserving effect of threshold.Excellent popularization using value and market outlook are arranged.
Description of drawings
Fig. 1 is provided with the structural representation of reinforced rib for the lower surface of flat fasten aluminium of the present utility model;
Fig. 2 is provided with the structural representation of concaveconvex structure for fasten aluminium of the present utility model;
Fig. 3 is the structural representation of connecting device between existing refrigerated container floor and the after-frame;
Among the figure: 1 fasten aluminium, 2 thermal insulation barriers, 3 back thresholds, 4 cushion blocks, 5 floors, 6 back-up blocks, 7 sealants, 8 fasten aluminiums.
The specific embodiment
Embodiment 1:
Referring to Fig. 1, fasten aluminium 1 upper surface is the plane, and lower surface has been provided with the square groove of booster action and the reinforced rib that " I " shape is supported, fasten aluminium 1 one ends are provided with buckle, the draw-in groove of this buckle and thermal insulation barriers 2 is inlayed mutually and is connected, the other end of fasten aluminium 1 and floor 5 overlap joints, and be welded to connect.Below fasten aluminium 1 and thermal insulation barriers 2, resistance to compression cushion block 4 is set, back-up block 6 is set below cushion block 4, back threshold 3 and back-up block 6 assembly weldings.Cushion block 4 and thermal insulation barriers 2 are installed, and draw-in groove is inlayed with the buckle of fasten aluminium 1 and is connected on the thermal insulation barriers 2, and guarantees that thermal insulation barriers 2 and back threshold 3 closely cooperate and correct position.Add sealant 7 in all junctions.
Embodiment 2:
Referring to Fig. 2, the certain position of fasten aluminium 8 upper surfaces is provided with the draw-in groove that two boss form, and this draw-in groove links to each other with groove on the side plate, can be used for the installation of door curtain track, to prevent cooling gas leakage; Fasten aluminium 8 lower surfaces have been provided with the square groove of booster action, and fasten aluminium 8 one ends are provided with buckle, and this buckle is inlayed with the draw-in groove of thermal insulation barriers 2 and is connected, the other end of fasten aluminium 8 and floor 5 overlap joints, and be welded to connect.Below fasten aluminium 8 and thermal insulation barriers 2, resistance to compression cushion block 4 is set, back-up block 6 is set below cushion block 4, back threshold 3 and back-up block 6 assembly weldings.Cushion block 4 and thermal insulation barriers 2 are installed, and draw-in groove is inlayed with the buckle of fasten aluminium 8 and is connected on the thermal insulation barriers 2, and guarantees that thermal insulation barriers 2 and back threshold 3 closely cooperate and correct position.Add sealant 7 in all junctions.
