Description

[Detailed Description of the Invention] (Object of the Invention) This invention is a laminated board formed by using a paper core as a core material. Provide a paper core laminate base material having a novel structure and a paper core laminate plate using the same, which prevents the occurrence of unevenness on the outer surface of the surface plate, which is the decorative surface, due to embedded trees, etc. It is what

(Prior Art) A laminated plate formed by using a paper core as a core material is widely used for furniture materials, construction materials and the like because of its strength, light weight and low cost. In order to make the structural strength of these laminated structure boards reliable, the classification and structure of the paper core are specified in detail in the Japanese Industrial Standards (JIS.
A6931), and if an optimum strength that conforms to this standard is adopted, it will be an advantageous laminated plate according to each application, but this kind of laminated plate is usually used as it is as a single unit. In many cases, it is often necessary to attach other members or metal fittings to one or both sides, or to perform groove processing or mortise processing to combine fittings and other things, so the core material part, In addition to this paper core, it is often formed in advance by combining wooden pieces such as a splint, a reinforcing piece, and a buried tree, or a crosspiece.

In the case where the core material is formed by combining a wooden piece or a crosspiece such as a splint, a reinforcing piece, or an embedded tree outside the paper core, the splint, the reinforcing piece, the embedded tree, etc. must be spread over the front plate and the back plate. It has a structure as shown in the sectional view of FIG. In the laminated board formed in this way, as long as it is used such that something is combined and hidden on both outer surfaces of the front plate and the back plate of the portion where the splints, reinforcing pieces, embedded trees, etc. are arranged. There is no particular problem,
When something is used that only the back side supports and something else for the other side is combined and the outer side of the front side is the same as it is, in the use state, the part where the splints, reinforcing pieces, buried trees, etc. are arranged and the paper If a flat top surface is not maintained on the flat surface of the core, the product value will be significantly reduced if this phenomenon occurs on a table top, etc. It will not happen.

The cause of the unsteady phenomenon in the splints, reinforcement pieces, and embedded trees that are placed in the core material is received from the outside by the face plate portion with the attached splints, reinforcing pieces, embedded trees, and other areas. The strength against pressure and the degree of influence from natural phenomena such as temperature and humidity are different, and the side plate parts attached such as sprues, reinforcing pieces, and embedded trees are in a fixed state due to the degree of deformation, which is small. It is considered that the other parts of the land become relatively free and become large, and cause the unsealed phenomenon at the boundary of both sides.

Therefore, based on the above knowledge, we worked on the realization of a paper core laminated base material and a paper core laminated board using it that at least prevent the occurrence of unsteady phenomena even on the surface that is visible, We have completed such a new structure.

(Structure of the Invention) As can be understood from the typical embodiment shown in the drawings, the paper core laminated base material of the present invention has a surface plate 1 formed on a decorative outer surface, except the inner surface outer peripheral predetermined width, The entire surface of one side of the paper core 2 is adhered and integrated, and the inner surface of the surface plate 1 is constructed so that no reinforcing material 5 such as a splint, a reinforcing piece, or a buried tree other than the peripheral materials 3, 3 ... Only the other surface of the core 2 is attached to the inner surface of the back plate 4 which is to be bonded and integrated with the surface, and a reinforcing material such as a splint, a reinforcing piece, a buried tree, etc.
5 is a paper core laminated base material which can be formed with the notch 21 according to the shape of 5 ... Or is formed in advance.

The surface board 1 is a natural wood decorative board having an appropriate thickness, or a decorative plywood in which a decorative thin board such as a board is attached and integrated only on the outer side. Similarly, the peripheral material 3 is also a natural wood square or a surface decorative thin board. It is formed from laminated laminated timber lumber.

The paper core 2 is not limited to the honeycomb structure as shown in the perspective view of FIG. 1 and the following drawings, but also has an S-shaped continuous structure, continuous single corrugated cardboard, continuous ribs in parallel, It is possible to adopt various structures such as a continuous fold shape.

The cut portion 21 of the paper core 2 is formed in conformity with the shape of the reinforcing member 5, and is a groove-shaped or hole-shaped reinforcing member such as a groove or a metal member formed on the outside of the back plate 4. The shape and structure of the reinforcing material 5 required for the above will be appropriately determined.

The paper core laminated base material of the present invention thus formed has the back plate 4 shown in the longitudinal sectional view of FIG. 3 laminated and not adhered, that is, one surface side of the paper core is exposed. The exposed surface is cut into a required shape in accordance with the shape and forming position of the reinforcing material 5 which is manufactured by the structure and is determined by the type of product to be completed, and is parallel to one peripheral material 3 in FIG. A cutout portion 21 as shown in the perspective view including the cut surface cut by the above-mentioned method and the longitudinal sectional view of FIG.
21 ... is formed and realized.

Therefore, as the base material, one surface side of the paper core 2 is always provided as a state in which the cutout portions 21, 21, ... Can be formed, or when the product to be manufactured is determined in advance. The corresponding notch 21,
21 ... Can be provided as a cutout.

(Other related inventions) FIG. 4 is a longitudinal sectional view showing the paper core laminated base material thus formed and the reinforcing member 5 shown in the longitudinal sectional view of FIG.
The laminated structure plate in which the attached back plate 4 is adhered and integrated is shown.

That is, the constitution of the laminated structure board using this paper core laminated base material is such that the peripheral materials 3, 3 ... Are attached to and integrated with the outer periphery of the inner surface of the face plate 1 formed on the outer surface of the makeup. 3, 3 ... The entire surface excluding the portion is bonded and integrated with one surface of the paper core 2 formed to have the same thickness as the peripheral material 3, and the inner surface of the surface plate 1 is a splint other than the peripheral material 3. Reinforcing piece, burying tree and other reinforcing material 5 does not abut at all, only the other surface of the paper core 2 is attached to the surface, the pier attached to the inner surface of the back plate 4, the reinforcing piece, The cut portions 21, 21 ... According to the shape of the reinforcing materials 5, 5 ... Are formed, and the other surface of the paper core 2 including the cut portions 21, 21 ,. It is formed by adhering and integrating the inner surface of the back plate 4 to which the reinforcing material 5 such as a reinforcing piece and a buried tree is attached. .

Since the back plate 4 is a plate that is not visible,
The outer surface (the surface that is not adhered to the paper core 2) does not need to be a plate that is particularly finished on the decorative surface like the surface plate 1, and may be appropriately finished according to the grade of the product to be completed. Plywood may be used.

The strength of the reinforcing member 5 is inevitably smaller than that of the member shown in the vertical sectional view of FIG. Not only a rectangular cross section as shown, but also a cross section of a member having a shape corresponding to a reinforcing rib, and a reinforcing member made of metal or other material is added to a surface that does not hinder in some cases. It is desirable to take measures such as appropriately adopting a reinforcing structure such as a structure for strengthening the connection structure with the peripheral members 3, 3, ...

(Effects and Effects) The paper core laminated base material of the present invention having the above-described structure is structured such that the reinforcing material 5 does not contact the inner surface of the surface plate 1, and the outer surface of the surface plate 1 of the product to be manufactured. On the side that becomes the base material, it becomes a basic material that can surely avoid the unsteady phenomenon caused by the reinforcing material 5 that must be placed in the paper core 2, and what kind of manufacturing should be performed. It has a high degree of freedom that it can deal with products freely.

Therefore, the paper core laminate using this paper core laminate base material is such that the reinforcement 5 never affects the surface plate 1 no matter where the reinforcement 5 is arranged. Since it is not used, a table top plate or other product is not used, and it does not cause a rough appearance phenomenon on its surface, so that the value as a product can be increased.

The paper core laminated base material and the paper core laminated board using the same of the present invention having such excellent characteristics can use the existing paper core laminated board manufacturing apparatus as they are and are easy to manufacture. Because of this, it is possible to manufacture at the same cost as this seed plate before.

As mentioned above, the present invention is intended to prevent the unprecedented phenomenon even from the seemingly destined surface of a laminated plate having a paper core as a core material, which is often used as a plate for furniture such as a table. The drawbacks that occur can be reliably avoided with a very characteristic structure, and will be extremely effective in increasing the added value of this type of product.
Moreover, since it can be realized by a simple method which is the same as the conventional method in manufacturing, the cost is not inferior.
