And a connecting portion 10b which has a connecting function with other members. The fitting portion 10a and the connecting portion 10b are formed to have substantially equal dimensions in the thickness direction, and an inclined portion 10c is formed between the two. Therefore, a step portion 10d is formed between the fitting portion 10a and the inclined portion 10c.

The connecting material fitting portions 7 formed at both ends of the wood material B have a fitting groove 7a for receiving the fitting portion 10a of the end connecting material 10 and a slope of the inclined portion 10c of the end connecting material 10. And a gradient portion 7b having a gradient equal to

As the intermediate material 11, a material having a rectangular cross section is used, and the intermediate material fitting groove 8 is also formed as a rectangular groove capable of receiving the intermediate material 11.

Next, the plurality of wooden materials B constructed as described above are combined with each other, and the end connecting material 10, the intermediate material
One procedure for composing a structural surface using 11 will be described.

First, the connecting members 10 are fitted into the connecting member fitting grooves 7 formed at both ends of the wooden material B, respectively. At this time, the connecting portion 10b of the connecting material 10 projects from both ends in the longitudinal direction of the wooden material B. Also, the intermediate material 11 is fitted into the intermediate material fitting groove 8 formed substantially at the center of the wooden material B,
Next, a new wood material B is arranged so as to face the divided surface 2 of the wood material B in which the connection material 10 and the middle material 11 have been fitted, and the connection material 10 and the middle material 11 are fitted in the respective grooves 7 and 8.

A lateral force is applied to the timber B, and the force causes the existing surface 1a of each of the adjacent wooden materials B to be pressed against the existing surface 1a of the wooden material B that is disposed opposite to the adjacent wooden material B. Are connected to each other.

Thereafter, by sequentially proceeding with the above-mentioned operation, a large number of wooden materials B are connected to each other, whereby the construction surface shown in FIG. 5 can be formed.

In the structure constructed as described above, one continuous connecting portion extending in the direction crossing the wood material B is provided at both ends in the longitudinal direction of the many wood materials B connected in the left-right direction.
10b is provided, and a flat surface of the connecting portion 10b is formed. For this reason, it is possible to absorb the dimensional tolerance in the length direction of the wooden material B by the connecting material 10, and easily carry out the work when joining the constructed structure to other members such as the building frame of the building. It is possible to

In the above-described construction, the unevenness of the wooden material B is exposed on the surface. Therefore, when this construction surface is a wall surface, the unevenness of the wooden material B can be directly expressed as a design on the indoor side. However, as shown in FIG. 7, it is preferable to provide an exterior plate 12 on the outdoor side surface.

As described above, when the plate 12 is provided on the surface of the construction surface, since the flat surface 4 is formed on the top of the wooden material B constituting the construction surface, the plate material 12 is brought into contact with the flat surface 4. It can be easily fixed with screws or nails (not shown). Thus, by attaching the plate 12 to the surface of the wooden material B, a space 13 is formed along the wooden material B by the plate 12 and the adjacent wooden material B, and this space 13 is formed as a ventilation space and a drain space. It is possible to function as.

When the construction surface is used as a wall surface, irregularities are also formed along the wooden material B on the indoor surface of the construction surface, and the irregularities are preferably used as spaces for wiring or piping. . In this case, it is not necessary to attach the entire surface of the wooden material B constituting the structural surface as in the case of the plate material 12 provided on the outdoor side surface.

[0045]

As described in detail above, in the surface structure according to the present invention, the groove is formed by combining the wooden materials aligned in parallel, and the wedge is fitted to the adjacent wooden material. It is possible to press and join the combined grooves together. For this reason, it is possible to form a firmly joined surface without using a metal material such as a reinforcing bar or a nail and an adhesive, and even in a case where the surface is to be removed, a wedge member is required. By removing, the wooden material constituting the surface can be easily removed.

Further, it is possible to manufacture a wood material from a material obtained by dividing a log material into two parts, and it is possible to reduce the loss of wood removal and to perform processing with simple steps. For this reason, when manufacturing wood, it can be processed with a general-purpose machine,
No special equipment is required, and manufacturing costs can be reduced.

The constructed surface has a folded plate-shaped cross section, and the specific strength with respect to the volume can be increased. Further, the space formed along the adjacent wood material can be used as a ventilation space, a drain space, or a space for wiring and piping.

Further, when constructing the surface, it is only necessary to use a wood material and a wedge as components, and the surface can be constructed with extremely few types of components. In addition, the size of the construction surface is determined by the number of wood materials aligned in parallel with the length of the wood material. Therefore, by appropriately setting the length and number of wood materials,
Various construction surfaces can be configured.

When a connecting member is provided in a direction perpendicular to the groove on the surface on which the groove of the wooden material is formed, movement of the connecting member in the direction along the groove is restricted by the connecting material. In addition, it can exert strength against a force acting in a direction along the groove. For this reason, it is possible to exhibit high strength against the out-of-plane bending force with respect to the structured surface.

When the construction surface is used as a wall surface, the timber shaft can be arranged in the vertical direction, which is structurally advantageous as compared with the school type.

Further, when constructing the construction surface, there is no work from the fore edge side of the construction surface, and it is possible to work from the surface side.
For this reason, even if it is a part surrounded by a frame or another construction surface, a construction surface can be constituted inside.

When a plate is provided on the surface of the constructed construction surface, the plate is used to restrain the wooden material so as to secure high strength against axial force, out-of-plane bending force and in-plane shear force. I can do it.
