Description
Technical field
The present invention relates to a kind of container bottom board and container bottom board unit thereof, the container bottom board that relates in particular to a kind of container bottom board unit of being made by fiber reinforced polymer matrix composite and become by this container bottom board unit spliced.
Background technology
In existing container structure, container bottom structure is main load bearing component.Container bottom structure comprises underframe and is layed in base plate on the chassis of container, and described chassis of container comprises two parallel and bottom side beams of vertical setting, at least one ground central sill that is " Ω " type or yi word pattern that is horizontally set at the some bottom cross beams between two described bottom side beams and vertically arranges.
Container bottom structure is as the main load bearing component of freight container, therefore chassis of container and the intensity and the good presentation quality that are layed in the base plate on the underframe thereof proposed higher requirement.There is the defective of the following aspects in existing container bottom board.
1, environmental-protecting performance: existing container bottom board is mainly wood floors, the long-term hard broadleaf of growing in South East Asia and other hylaeas that relies on is cloned the hardwood such as (Keruing) and A Bidong (Apitong), because the very long and excessive felling of growth cycle of such seeds, cause the large tracts of land of hylaea in the world wide to disappear, the resource worsening shortages, and environmental protection pressure is increasing, and it is the theme that the industry personage is exploring always and assaulting fortified position that material substitutes.
2, lightweight: the density of conventional wooden container bottom board unit causes the freight container overall weight to strengthen about 800KG/ cube, no matter be that vehicular transport or seagoing vessel transportation all waste energy, lightweight direction in container bottom board unit is development tendency.
3, mounting characteristics: conventional wooden container bottom board unit need spread 12 base plates at least in a forty foot equivalent unit, installation procedure is with artificial or equipment bottom board unit to be taped against in the case on the underframe, to plug in pricker location (manually), setting-out all around and hole and locate, hole, spread a plurality of operations such as nail, locking, labour intensity is large, and efficient is low.
4, connecting method: the erection method of traditional container bottom board unit generally is to offer tenon mouth and " Ω " type or yi word pattern ground central sill or bottom side beams angle steel in bottom board unit one side mutually to be spliced by sealant, this erection method can play sealing function by actv., but when adjacent two base plates when being subject to asynchronous application force, the monolithic bottom board unit just can produce the displacement of distortion or trace, and then formation causes local failure or the lamination of adjacent two bottom board unit Contact positions to the extruding of adjacent bottom plates unit.Traditional container bottom board often all is that the local failure owing to the assembly unit interface causes scrapping of base plate, affects base plate service life.
Therefore seek a kind of environmental protection, high-quality, efficient, and have the baseboard material of good processing characteristics, light weight and bottom board unit structure and the connecting method of corresponding construction thereof, become the task of top priority of whole container industry in order to guarantee the harmonious common prosperity of the mankind, nature and development.
