Description

Reinforced wood composite panel

The invention relates to a plate structure, in particular to a reinforced wood composite board which has both material cost and structural strength.

According to the conventional composite board structure, at least one complete piece of wood is disposed in the middle, and a wooden panel is attached to the surface of the original wood piece, so that the piece of the wood piece is not easily damp and deformed, but the obtaining of the wood is not easy, and the unit price is obtained. High, resulting in a substantial increase in the cost of composite panels, which reduces the acceptance of the general public, and a large number of illegal logging will also cause environmental damage. On the other hand, if the logs are defective, damaged or cracked in production. If the defects or cracks of the logs are directly sandwiched in the wood panel, the body will be partially hollow and have insufficient structural strength, and if the defects, damage or cracks are cut and discarded, the whole block is formed. Cutting the leftover material will cause waste on the wood, and it is limited by the hardness, deformation, volume, variety and other conditions of the log. The type of wood that can be used for the composite board is limited, so it is difficult to combine its production cost and structure. Strength, this is the technical problem that the creative wants to improve.

Looking at the above-mentioned conventional structure is not difficult to find that there are still some shortcomings. The main reasons are as follows:

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a reinforced wood composite panel in view of the above-mentioned shortcomings existing in the prior art.

A composite panel is formed by splicing a plurality of panels, and the panel is obtained from economical wood capable of rapid growth, and the sheet is formed by forming at least one joint surface and at least one connecting side edge, and the plurality of panels The bonding surface is bonded to the connecting side by a plurality of adhesive layers to form an adhesive bond, and a coating layer is formed by extrusion coating on the entire surface of the plate, so that the covering layer completely shields the plate.

Wherein, the plate can be formed with a groove at the recess and the crack, and the groove is filled by the coating layer to increase the bonding strength between the plate and the cladding layer.

Wherein, the sheets are dried before being bonded, and the outer moisture is blocked by the coating layer.

Wherein, the coating layer is formed with a wood grain surface.

Wherein, the plate is formed with a toothed surface at the connecting side, that is, the bonding area of the connecting side can be improved, and the connection positioning effect of the plate is also provided.

Among them, the composite panel can be arranged to form a ceiling, a floor or a wall.

A first main object of the present invention is that the sheet can be cut from rapidly growing economical wood, and the sheet is formed with at least one joint surface and at least one connecting side edge, and the sheet can be matched with the defect of the body. The defective parts such as damage or cracks are processed to form grooves, thereby retaining the bad parts of the sheets, thereby improving the utilization of the sheets, and increasing the range of the wood to be used, and placing the bonded composite sheets into the mold. And pressing the surface of the sheet with a mold to cover the coating layer, and the coating layer can simultaneously fill the groove of the sheet, and the combination of the sheet and the cladding layer can be improved by filling the groove Strength, which can effectively reduce the cost of materials, to improve its practicality.

A second main object of the present invention is that the coating layer can be formed with a wood grain surface. Use wood grain surface to achieve the effect of imitation wood appearance, or surface processing to form different colors or textures, to improve its variability, and also to prevent the corrosion effect of the plate through the coating layer to block moisture, thereby enabling both Its durability and applicability.

Other objects, advantages and novel features of the invention will be apparent from the description and appended claims.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [Simplified Description of the Drawings] for details:

First, please see the first and second figures, a reinforced wood composite panel, The utility model comprises: a composite board 10 and a cladding layer 20, wherein a composite panel 10 is formed by splicing a plurality of panels 11 which are taken from economical wood capable of rapid growth, and the panel 11 is processed and formed. There are at least one joint surface 111 and at least one joint side 112, and the plurality of adhesive sheets 113 are bonded to the joint surface 111 and the joint side 112 by a plurality of adhesive layers 113 to form an adhesive bond, and the panel 11 is connected to the joint side. A toothed surface is formed at the edge 112, that is, the bonding area of the connecting side 112 can be improved, and the connection and positioning effect of the plate 11 is also provided, and the plates 11 are dried before being bonded, and a coating layer is formed. 20 is formed on the entire surface of the sheet 11 by extrusion coating, so that the coating layer 20 completely shields the sheet 11 and blocks the external moisture by the coating layer 20, and the coating layer 20 can fill the sheet 11 a recess and a crack, and the plate 11 can be formed with a groove 114 at the recess and the crack, and the groove 114 is filled by the cover layer 20 to increase the bonding strength between the plate 11 and the cover layer 20, thereby The defective portion of the sheet 11 is retained, thereby improving the effective utilization of the sheet 11 to reduce the production cost of the composite sheet 10. Both structural strength.

The combination of the structures can be viewed from the first figure to the seventh figure. The sheet 11 of the present invention can be cut from the economical wood which grows rapidly, and the sheet 11 is formed with at least one joint surface. 111 and at least one connecting side 112, and the connecting side 112 is formed with a toothed surface, and the plate 11 can be processed to form a groove 114 with a defect such as a defect, a damage or a crack of the body, thereby retaining the plate 11 The bad part, thereby improving the utilization rate of the sheet 11, can also increase the range of the optional wood, and the processed sheet 11 is dried to remove the internal moisture. When the composite board 10 is combined, the adhesive layer is first used. 113 is disposed at the connecting side 112 of the two plates 11, thereby forming the area of the composite plate 10, and simultaneously increasing the bonding area of the connecting side 112 by using the toothed surface, and also having the connection positioning effect of the plate 11. Then, the glue layer 113 is disposed on the joint surface 111 of the plate 11, so that the plates 11 can be stacked and bonded to each other to form the thickness of the composite plate 10, and further the entire composite after bonding. The ply 10 is placed in the mold A, and the surface of the plate 11 is press-coated with the coating layer 20 by the mold A, thereby allowing the plurality of sheets 11 to have an overall surface appearance, and the coating layer 20 can simultaneously Filled in the groove 114 of the plate 11, the bonding strength between the plate 11 and the cladding layer 20 can be improved by filling the groove 114, and the creation uses the plate 11 to replace the log, and can effectively utilize the cutting of the log. By cutting the leftover material, it is also possible to cut the sheet 11 by economical wood which can grow rapidly, which can effectively reduce the material cost and improve its practicability.

For the actual use, the coating layer 20 can be formed with a wood grain surface, and the wood grain surface can be used to achieve the appearance of the original wood, or the surface processing can be formed differently, as shown in Fig. 8 to Fig. 11 .
