Solid structure with grooves on two opposite surfaces in thickness direction and uses thereof

Abstract

This invention discloses a solid structure with grooves and its use. Wherein the deepness sum of the two grooves on the two opposed faces which compose the thickness of this solid is more the solid's. The direction of the solid structure that is vertical to the groove is easily to be compressed, stretched or bent, which can solve the technique problems caused by the solid heat expansion and cold contraction or the humidity expansion and dry contraction. This solid structure can be applied to the road, the building, the bridge, the rail, the conduit or other telescopic device with long components, which can also be used as the press plate. If the solid material is the timber or the artificial board, the solid structure can also be used for the compound artificial board, the bamboo compound board, the compound floor board, the geothermal board, the core-board, the thick core veneer sheet, the concrete slab, the container, or the compartment bed, the wooden door, the furniture part, the curved veneer sheet, the curved compound sheet, the core board of the compound board pipe besides for board used directly, if the solid material is the wooden board, it can be used for the compound board.

Description

technical field [0001] The invention relates to a solid structure having grooves on two opposing surfaces constituting the thickness, and to the use of the solid structure. technical background [0002] Solids expand and contract with changes in temperature and humidity. For solids with larger sizes and larger elastic modulus, when the volume expansion and contraction caused by changes in temperature and humidity are limited by constraints, the solid Considerable stress will be generated in the solid body, and when this stress exceeds a certain limit, it can lead to the destruction of the solid itself, or the destruction of the constraints that limit its expansion and contraction. Thermal expansion and contraction of roads, bridges, buildings, rails, pipes and other long components are common technical problems in engineering. In the field of wood processing or composite materials, the expansion and shrinkage of solids or thermal expansion and contraction will cause excessi...

AI Technical Summary

Problems solved by technology

When the temperature and humidity change, the expansion and contraction of the solid will not lead to its own destruction, nor will it cause the constraints limiting its expansion and contraction to be destroyed. question
