Since when between rib 4, forming urethane 3 by expansion phase wooden rib can be heated to about 80-100 ℃, so the wooden moisture content of bar 4 that helps can overflow from rib 4, thereby forms the gap between rib 4 and urethane 3.Transmit because understand between the inboard of freight container and the outside in above-mentioned gap, heat, make the refrigeration effect of freight container reduce.
2. because refrigerated container disposes a refrigeration system that has an electrical motor, electric current may flow through the rib 4 that is full of moisture, can often cause the short circuit of refrigeration system like this.For the above-mentioned short circuit that prevents to be caused by the rib that is full of moisture, rib 4 should be coated with an insulating tape respectively.
3. the outside face owing to wooden rib 4 is simple flat surface, the diffusion of urethanes when rib 4 can not prevent to form urethane 3 between rib 4.When urethanes spreads as mentioned above like that, will between urethane 3 and rib 4, form the gap, thereby reduce the refrigeration effect of freight container.
Therefore, what the purpose of this invention is to provide a kind of refrigerated container prevents the heat conduction bottom construction, wherein, the problems referred to above that caused by the typical structure with wooden rib can be overcome, this bottom construction has a plurality of synthetic resin sticks, these synthetic resin sticks are applicable to the inboard and the heat conduction between the outside that prevent container base, be convenient to desire the expansion phase of the urethane that forms between the synthetic resin stick, can not cause the gap between synthetic resin stick and urethane and not need to apply insulating tape.
In order to realize above-mentioned purpose, the invention provides a kind of solar heat protection conductive base structure of refrigerated container, this bottom construction comprises rail bar of a plurality of ends, a upper plate that is used to support those end rail bars, a lower plate that is placed on this upper plate below and a space is arranged between the two, with a heavy parts that rises that is used for mentioning freight container with the crotch of weight-lifting equipment or crane, also include: a plurality of sticks made from the synthetic resin foam, these sticks are placed in like this, in the space between the lower plate, make stick separate with fixing compartment, the opposite flank of each stick has groove and injustice; And a plurality of urethane that between stick, form by expansion phase, they are used to support upper plate and prevent at the inboard of container base and the heat conduction between the outside.
Above-mentioned and other purpose, feature and other advantages of the present invention can be from below in conjunction with obtaining clearer understanding, wherein the detailed description of accompanying drawing:
Fig. 1 is the block diagram of the semi-sictional view of typical refrigerated container;
Fig. 2 is the cutaway view of bottom of the typical refrigerated container of Fig. 1, shows to use a plurality of wooden ribs not only to be used for supporting upper plate, and is used for fixing anti-heat conduction urethane;
Fig. 3 is the view corresponding to Fig. 2, but the situation that a plurality of synthetic resin stick used according to the invention replaces wooden rib is shown; With
Fig. 4 is one a block diagram in the stick of the present invention.
Fig. 3 is the cutaway view of bottom with refrigerated container of a plurality of sticks of the present invention.In this figure, label 1 indicates freight container or refrigerated container.The bottom of freight container 1 comprises rail bar 2 at the bottom of the representative type that separates with fixed interval.
Between stick 7, form a plurality of urethane 3 by expansion phase.The side closed contact that vertically is carved with groove of urethane 3 and stick 7.
Lower plate 9 is being supported by a plurality of arrangements angle rod 5 in its lower section.What the base plate of freight container comprised also that a crotch (not shown) that is used to utilize weight-lifting equipment or crane mentions freight container 1 plays heavy parts 10.
When using above-mentioned synthetic resin stick 7 to replace the wooden rib 4 of representative types, the bottom member of freight container has following advantage.
1. because stick 7 of the present invention is different with wooden rib 4, be make with synthetic resin and be not full of moisture, therefore, even stick 7 is heated to high temperature in the expansion phase of the urethanes of urethane 3, can not form the gap between stick 7 and the amino methyl methacrylate layer 3 yet.Therefore, stick 7 makes container base can prevent the inboard of freight container 1 and the heat conduction between the outside, has improved the refrigeration effect of freight container 1 thus.But, the wooden rib 4 of representative type has the moisture content of about 15-20%, thereby in the expansion phase of urethanes can overflow wooden rib 4 and infiltrating in the urethane 3 of moisture content, between rib 4 and urethane 3, form the gap thus, cause by container base generation heat conduction.
2. the synthetic resin of stick 7 of the present invention has excellent insulation property inherently, makes synthetic resin stick 7 not need to be coated with extra insulating tape.But 4 on the wooden rib that is full of moisture content should be coated with insulating tape; Otherwise electric current can flow through rib 4, causes the short circuit of the refrigeration system of freight container.
