Abstract

The utility model provides a spliced wood board which is formed by inserting everting sharp corner barbs, wherein a group of everting sharp corner barbs formed by obliquely splitting a section of opening from the edge of a body are uniformly distributed at intervals on the butt joint end surfaces of unit wood sheets, the shape of the opening is matched with that of the everting sharp corner barbs, the shape and the distribution positions of the everting sharp corner barbs on the butt joint end surfaces of two adjacent unit wood sheets are the same but the sharp corners are opposite, the everting sharp corner barbs of the two adjacent unit wood sheets are obliquely inserted into the openings of the opposite unit wood sheets corresponding to the everting sharp corners, the other butt joint end surfaces of the two adjacent unit wood sheets are attached together, and an adhesive is further arranged between all the butt joint end surfaces of the two adjacent unit wood sheets for bonding connection. When the everting sharp corner barbs of the butt joint end surfaces of the unit wood sheets are processed, no material is needed to be removed, wood loss is avoided, the total length of the spliced wood sheets is consistent with the accumulated length of the unit wood sheets, and wood resources can be effectively saved.

Description

Spliced wood board adopting everting sharp corner barb for insertion Technical Field The utility model relates to a spliced board, in particular to a spliced board which is spliced by adopting an everting sharp corner barb. Background In order to improve the wood benefit rate, short and narrow wood chips or scraps are further processed and spliced into large-size plates for use, so that the wood waste is reduced, and the resources are saved. At present, most of splicing wood boards on the market are spliced in a finger-shaped inserting mode, namely butt joint end faces of unit wood chips to be spliced are processed into saw-tooth tenons capable of being inserted in a finger-shaped mode by using a milling cutter, then adhesive is coated on the tenons, the unit wood chips coated with the adhesive are spliced into large-size wood boards in the finger-shaped inserting mode, and the splicing wood boards can be completed after the adhesive is fully solidified. When the unit wood pieces of the finger-shaped inserting spliced wood board are processed into the saw-tooth tenons on the butt end surfaces, certain materials are required to be removed, so that part of wood is lost, the splicing length is reduced when the finger-shaped interfaces are adopted for insertion, the total length of the spliced wood board is shorter than the accumulated length of the unit wood pieces, when the spliced wood board is spliced by a plurality of unit wood pieces, the total lost wood is larger, and finally the total length of the obtained spliced wood board is shorter than the accumulated length of the unit wood pieces, so that wood is wasted. Disclosure of utility model The utility model aims to provide a spliced wood board which is spliced by adopting an everting sharp corner barb, any material is not required to be removed when the butt end surfaces of unit wood sheets are processed, wood loss is avoided, and the total length of the spliced wood board is consistent with the accumulated length of the unit wood sheets. The technical scheme adopted by the utility model is as follows: A spliced wood board formed by splicing at least 2 unit wood chips with the same thickness is formed by splicing the unit wood chips, wherein a group of everting sharp angle barbs formed by obliquely splitting a section of opening from the edge of each unit wood chip are uniformly distributed at intervals, the shape of each opening is matched with that of each everting sharp angle barb, the shape and the distribution positions of the everting sharp angle barbs on the butt joint end surfaces of two adjacent unit wood chips are the same but the sharp angles are opposite, the everting sharp angle barbs of the two adjacent unit wood chips are obliquely inserted into the openings of the opposite unit wood chips corresponding to the everting sharp angle barbs, the other butt joint end surfaces of the two adjacent unit wood chips are attached together, and an adhesive is further arranged between all the butt joint end surfaces of the two adjacent unit wood chips for bonding connection. The unit wood pieces of the spliced wood board are spliced in an everting sharp corner barb inserting mode, and are adhered and connected by the aid of the adhesive, when the everting sharp corner barbs of the butt joint end surfaces of the unit wood pieces are processed, only a section of notch is required to be obliquely split to the butt joint end surfaces of the corresponding positions of the unit wood by utilizing a processing cutter in a directional and quantitative mode, so that the everting sharp corner barbs matched with the notch are formed, any material is not required to be removed, wood loss is avoided, the total length of the spliced wood board is consistent with the accumulated length of the unit wood pieces, and wood resources can be effectively saved.
