Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to composite materials that form long, thick architectural structural members from relatively short, thin component materials.

Traditionally, this composite material of cypress is made by laminating multiple sheets of constituent materials, protruding and receding each edge alternately to create a non-woven material, and then making a continuous piece of laminated material by butt-jointing each end face. By doing so, some materials are made into long and thick structural materials for construction. However, this synthetic material lacks cushioning properties because each surface is butt-jointed, and moreover, due to the negative force applied to the board surface in the orthogonal direction, the direct overlapping deflection causes peeling on the butt end surface and amplifies it between the upper and lower surfaces. This has the disadvantage of causing an overall peeling phenomenon.

The object of the present invention is to provide an improved composite material to eliminate these drawbacks.

That is, in the synthetic material according to the present invention, the edges are sequentially shifted stepwise to 1! ! It is constructed as a long and thick material by laminating and gluing several pieces of component material, and then consecutively joining the laminated materials with a slight distance between the adjacent end faces of the shifted edges. There is.

This will be explained below based on the illustrated embodiments.

In the illustrated embodiment, the constituent material a and
..., h..., C..., and stack them in the first stage, 4. A composite material is constructed by laminating and adhering B and C and continuously connecting the laminated materials to each other in a second step.

Constituent materials a..., b..., C...
... are relatively short and thin, and all are formed to have the same thickness and length. In the ring direction of each plate, one plate may be used or several plates may be tapped and taped.

A laminated board (see FIG. 2) temporarily bonded with Tetoron-based adhesive or the like can be used.

When forming each of these constituent materials into a laminated material, each edge 6. ......, bl..., C1...
are sequentially shifted in stages between the top and bottom and laminated and bonded. It is preferable that the shifting dimensions are each a fixed dimension,
Alternatively, the laminated materials A, B, and Cd can be formed by dividing each block into upper and lower blocks, and then bonding the upper and lower parts to each other. Each of the laminates A, B, and C is formed to have the same arbitrary thickness.

Next, these laminated materials A, B, and C are

that time,.

There is a slightly wide gap α between each end face,..., A2...
. . , C3 . . . are attached at intervals. This interval is formed in the same way for each layer.

In the synthetic material constructed in this way, the gap α1...

Due to the existence of voids caused by b, . able to demonstrate. These gaps can be created over the entire length of the composite material by adjusting the gap spacing or the thickness of the laminate so that the edge of the top layer of laminate A and the edge of the bottom layer of laminate B are aligned. distribution.

(9) Due to the existence of these gaps, even if the end faces of the constituent materials of each layer are bent due to load, stress that would not build up due to bumping will not occur, and each laminate material A.

Since the bonding portions between B and C exist in a stepwise manner, a pressing force can be applied to each bonding portion between each layer. Therefore, this composite material can have better cushioning properties due to the voids, and can also be made strong without causing delamination.

Note that this synthetic material is used as a structural material for construction such as flooring boards 9, scaffolding boards, columns, beams, etc., and is suitably cut and formed into necessary dimensions according to each use.

As described above, the synthetic material according to the present invention can be formed at low cost because it can be formed using scrap materials, etc., and has sufficient cushioning properties and a strong form that does not cause gradual peeling. Can be done.
