Problems solved by technology

[0006] However, since the surface of the grooved core board has grooves, and the grooves run through the front, rear and left and right end faces of the grooved core board, the position of the end faces of the grooved core board is relatively weak, and it is difficult to install the grooved core board. The end face of the grooved core board is cut to form a lap joint to connect other core boards. When cutting, the end face of the grooved core board is very easy to crack and break. Therefore, although the grooved core board of this structure reduces the warpage of the board The problem of deformation, but it is not convenient to set up the overlapping structure between the plates, and it is not convenient for the alignment and splicing of the plates

Embodiment Construction

[0055] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0056] see figure 2 and image 3 As shown, the grooved core board 10 of the present invention is mainly composed of a core board body 11 and a connecting edge 12 arranged on the end surface of the core board body 11. The surface of the core board body 11 is provided with an angle range of 30°. °~90° groove, the connecting edge 12 is provided with a splicing structure for splicing with the adjacent grooved core board (the splicing structure is not shown in the figure). The grooves run through the corresponding end faces of the core board body 11. The core board body 11 is a strip-shaped board body, including a long side and a short side. The grooves include a main groove 131 arranged on the surface of the core board body 11 along the long side. The short sides are disposed on the sub-grooves 132 on the surface of the core board body 1...

Abstract

The invention discloses a groove-type cross-band veneer, and a sheet material prepared from the groove-type cross-band veneer. The groove-type cross-band veneer comprises a cross-band veneer main body, wherein the surface of the cross-band veneer main body is provided with grooves; and connecting edgings arranged on the end surfaces of the cross-band veneer main body; the connecting edgings are also provided with splicing structures used for splicing with adjacent groove-type cross-band veneers. According to a preparation method, the surface of the cross-band veneer main body is provided with the grooves so as to cut connection of surface fiber of the cross-band veneer main body, reduce superposition of buckling deformation of the surface of the cross-band veneer main body, and help to release internal stress of the cross-band veneer main body; the end surface of the cross-band veneer main body are provided with the connecting edgings, the connecting edgings are provided with the splicing structures used for splicing via cutting, and connection of the cross-band veneer main bodies is realized via the connecting edgings, so that cutting of the end surfaces of the cross-band veneer main body is avoided, and the end surfaces of the cross-band veneer main body is protected from being damaged.

Description

technical field [0001] The invention relates to a composite board, in particular to a grooved core board and a board with a grooved core board. Background technique [0002] Most of the wood panels on the market now include solid wood panels and solid wood composite panels. The solid wood panels are entirely made of logs, which consume a large amount of noble logs, have a high cost, and are hard in texture, easy to shrink and swell, and tile-like deformation. The solid wood composite panel is formed by the combination of the glued panel layer, the core panel layer and the bottom panel layer. The panel layer is usually a melamine treated panel layer. The overall plate formed by resin bonding and hot pressing. The bottom layer is usually a balanced moisture-proof paper layer impregnated with melamine resin. Compared with the traditional solid wood plate, the multi-layer solid wood composite plate of this structure improves the strength and durability of the plate. , and accor...
