Abstract
Description
Technical Field
[0001] The utility model belongs to a composite board, in particular to a directly assembled composite board made of discarded wooden boards. Background Art
[0002] Waste wood refers to wood materials that no longer have their original use value due to various reasons after being used in construction, furniture manufacturing, decoration or other related fields. These wood boards may be abandoned due to damage, aging, obsolescence, design changes or leftovers after the completion of the project. If they are not properly handled, it will not only cause a waste of resources, but also may have a negative impact on the environment, such as occupying land space and generating garbage pollution. At present, there are many ways to reuse waste wood. The most common way is to process the recycled waste wood into various environmentally friendly building materials or products, such as particleboard, fiberboard, etc., to achieve resource reuse.
[0003] When manufacturing composite boards, these waste wood boards need to be processed in multiple steps and finally cut and trimmed into boards or strips of required length, width and thickness. Since the waste wood boards themselves have more or less defects, after cutting and trimming, in addition to boards or strips that meet the size requirements, there are also boards or strips of different sizes. The current composite board manufacturing method is difficult to utilize these boards or strips of different sizes, resulting in a very low material utilization rate when using waste wood boards to manufacture composite boards.
[0004] In response to the above situation, the Chinese invention patent with application number 2021103009972 discloses a waste wood strip splicing wood floor and its preparation method, which discloses that the waste wood strips are connected end to end and laid flat, and assembled into a reinforced core board through an adhesive layer, and the top and bottom of the reinforced core board are bonded and assembled with composite panels through an adhesive layer, and the side walls on the opposite side of the reinforced core board and the composite panel are evenly provided with transverse tie grooves arranged perpendicular to the waste wood boards, and the transverse tie grooves are snap-fitted with reinforced tensioning wood strips, and the side walls of the composite panel away from the reinforced core board are sprayed with a protective paint layer. The composite board improves the overall strength and protective performance of the board by strengthening the core board, the composite panel, the tensioning wood strips and the protective paint layer, but such an arrangement will lead to a complex overall structure, many processing steps and high cost; in addition, the splicing method of the reinforced core board adopts the end-to-end splicing of the waste wood boards, and the waste wood boards are evenly laid side by side, and then the adhesive is spread and filled in the gaps between the waste wood boards to form an adhesive layer, so as to fix and limit the waste wood boards and bond them. Although this method is simple in process, the waste wood boards are not strongly correlated, resulting in low overall strength of the reinforced core board. Utility Model Content
[0005] The purpose of the utility model is to overcome the problems of low material utilization rate and high cost in the existing composite board manufacturing using waste wood boards, and to provide a direct-joined composite board with a simplified structure, high material utilization rate and strength, and low cost.
[0006] The utility model solves the technical problem by adopting a technical solution: a straight-jointed composite board comprises a base plate, the base plate is formed by a plurality of straight-jointed wood strips laid flat and joined together, the straight-jointed wood strips are glued together, and a filling protective layer is arranged on the upper and lower surfaces of the base plate.
[0007] Optionally, the base plate is formed by a plurality of straight wooden strips that are staggered and laid flat.
[0008] Optionally, the straight-jointed wooden strips are composed of a plurality of small wooden strips, which are connected end to end with mortise and tenon joints.
[0009] Optionally, there are multiple substrates, which are stacked and glued to each other.
[0010] Optionally, the upper and lower filling protective layers of the substrate are covered with fireproof boards, and the fireproof boards are glued to the filling protective layers.
[0011] The use method and principle of the utility model are as follows: glue is applied to the sides of a plurality of straight-joined wood strips, and the strips are laid flat and joined to form a base plate. Glue is applied to the sides of each straight-joined wood strip, and the straight-joined wood strips are connected more tightly by gluing the sides. A filling protective layer is arranged on the upper and lower sides of the base plate composed of the straight-joined wood strips, and the filling protective layer fills the unevenness of the straight-joined wood strips on the upper and lower sides, and at the same time, the connection between the straight-joined wood strips is further strengthened and the straight-joined wood strips are protected. The above structure does not impose strict requirements on the length, width and thickness of the straight-joined wood strips, and the size can be within a certain range, so that waste wood boards can be processed into more straight-joined wood strips, thereby improving the material utilization rate.
[0012] When processing thinner waste wood boards, the straight wood strips of the base plate adopt a staggered flat structure. When the base plate is partially subjected to external force, the external force can be smoothly spread to the straight wood strips of the entire base plate, and multiple straight wood strips will bear the force together, thereby improving the strength of the base plate;
[0013] When processing thicker waste wood boards, the straight wood strips of the base plate are composed of multiple small wood strips, which are connected end to end with mortise and tenon joints to improve the overall strength of the base plate. When the base plate is partially subjected to external force, the external force can be smoothly diffused to each small wood strip of the base plate, and is jointly borne by multiple small wood strips, thereby improving the strength of the base plate;
[0014] The straight-joined composite board of the utility model can have multiple base plates to increase the overall strength, can also be composited with fireproof boards to increase functionality, and can also be used as a composite material for other boards, so it is very flexible to use.
[0015] Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure, high material utilization rate and strength, low cost, and flexible use. BRIEF DESCRIPTION OF THE DRAWINGS
