Anti-bending board

Abstract

The invention discloses an anti-bending board, and belongs to the technical field of boards. According to an existing board, the structural strength is enhanced by arranging a frame, the length of steel tubes in the same direction with the frame is same, the anti-bending performance of the steel tubes is same, and the tubular structures of steel or wood can deform to a certain extent under the action of self gravity and environmental factors along with the extension of the length of the tubular structures, so that the anti-deforming effect of the frame structure is poor. The board comprises aboard body with a flat outline, the board body is fixedly provided with a supporting part formed by combining at least two rod pieces with different lengths in an assembled mode, and the structural strength of the supporting part is greater than the anti-bending strength of the board body. The board has the beneficial effects that in order to reduce the deformation amount of the long rod piece andenhance the structure of the long rod piece, the prone-to-deform section adjacent to the long rod piece, of the short rod piece is fixedly connected to the board body, the anti-bending performance ofthe long rod piece is improved by utilizing the better anti-bending performance of the short rod piece, so that the long rod piece has the structural strength same as that of the short rod piece, andthen the structural strength of the board is improved.

Description

technical field [0001] The invention relates to a bending-resistant board, which belongs to the technical field of boards. Background technique [0002] Conventional rectangular plates are large in size and small in thickness. After the surface is pressed, it is easy to bend and deform. [0003] When wooden boards are affected by humidity, temperature and pressure, warping and deformation will occur. In order to improve the stability of wood dimensions and prevent wood deformation, it is generally relieved by adding adhesives or installing waterproof coatings or soaking in chemicals. But it can only delay the deformation time of the plate, or the anti-deformation effect is poor, and the above-mentioned means need to use more glue and chemical coatings, which will release a large amount of harmful gas, which is not environmentally friendly. [0004] Chinese patent (publication number: CN200982515) discloses a steel wood board, which contains a splint, and a square frame is e...

Problems solved by technology

[0006] However, the steel pipes in the same direction of the framework of this scheme have the same length and are arranged in parallel. The bending resistance of each steel pipe is the same, and the overall bending resistance is limited, which still depends on the bending resistance of the steel pipes of equal length. The extension of the length, whether it is steel or wood, will deform to a certain extent under its own gravity and environmental factors, so the anti-deformation effect of the above-mentioned frame structure is not satisfactory
