Description

[Detailed Description of the Invention] This invention relates to structural materials used as walls, beams, and flooring materials of wooden buildings, and more specifically to panel structural materials formed by combining short, small-diameter trees.

In recent years, the merits of wooden buildings have been reconsidered, but construction using conventional construction methods is costly and takes a long time, so improvements are strongly desired.

In addition, the processing of small-diameter trees such as thinned wood in lumber production is becoming a serious problem nationwide.
There is an urgent need to expand the uses of small diameter trees.

Therefore, it has been considered to use small-diameter wood as a high-value-added housing material, but small-diameter wood has strong curls and twists, making it impossible to use it as a building material as long as it is. Unless this issue is resolved in the near future, we cannot hope for expanded uses for small-diameter trees.

Furthermore, wall materials and ceiling materials in buildings are required not only to have good appearance but also to have a sound absorbing effect.

This idea was made in consideration of the above points, and by using shortened small-diameter wood, it is possible to solve the problems caused by the habit of small-diameter wood, and it is also an interior wall material with excellent sound absorption effect. The purpose of the present invention is to provide a panel structural material that can be used as a ceiling material or as a ceiling material, and that can realize the effective use of small-diameter wood as a building material.

The structure of this invention is to form the side edge materials, braces, and intermediate materials using square timbers with cross-sectional shapes with chamfered corners along the grooves and longitudinal direction, and between the side edge materials arranged parallel to each other on both sides. Arrange multiple sets of crossed braces, fill the spaces between the side edge materials and between the braces with intermediate materials, and fill the overlapping parts of each
The grooves are joined by fitting the grooves, and grooves are formed on the surface by chamfering, and the grooves provide a sound absorbing function.

This invention will be explained below based on the embodiments shown in the accompanying drawings.

As shown in FIG. 1, the panel structure material 1 includes a pair of side edge members 2, a plurality of sets of brace members 3 installed between the side edge members 2, and an intermediate member installed between the side edge members 2 and between the brace members 3. 4, and each of the side edge material 2, brace material 3, and intermediate material 4 is a square material A as shown in FIG.
It is formed using

The above-mentioned square timber A is made of small-diameter wood, and has a cross-sectional shape with a groove B in the longitudinal direction on one side and a groove C on the other side, and chamfers D on the four corner edges along the longitudinal direction. .

The side edge material 2 is made of square material A with the length required for the panel structural material 1, and the brace material 3 is processed into a right-angled V-shape at both ends, and is placed in the center position as shown in FIG. A recessed notch 3a is provided into which the mating braces to be combined in a cross-like manner are fitted.

The intermediate material 4 is a long member 4a that is assembled between the edge materials 2 on both sides.
There are two types of diagonal members 4b, which are assembled between the crossed brace members 3.

The shape and arrangement of the grooves C provided in each of the side edge members 2, the brace members 3, and the intermediate member 4, and the grooves C into which the grooves B fit are shown in the exploded view of FIG. When assembled in the order shown in Fig. 4, the grooves B and C fit into each other as shown in Fig. 4.

As described above, when each groove material is assembled in order, the chamfers D provided on the square material A will be adjacent to each other, and this chamfer D will form the groove 5 on both sides of the panel structural material 1. become.

Due to the presence of the groove 5 formed by the chamfer D, the surface of the panel structural material 1 loses directionality with respect to sound,
The sound absorption effect will be greatly improved.

In addition, the fitting portions of B and groove C are fixed with adhesive, and as shown in FIGS. A bolt 9 may be inserted through a through hole 8 along the longitudinal direction of the intermediate member 7 and the intermediate member 4 and tightened with a nut.

The panel structure material 1 shown in FIG. 1 is used as a wall material of a building, and three sets of crossed brace materials 3 are provided in the longitudinal direction between the side edge materials 2, and each brace material 3 Three long members 4a are installed between each of them, but as shown in Fig. 6, the length can be changed by using two sets of crossed brace members 3 to shorten the length of the beam structure. The size can be freely selected depending on the purpose.

The width of the panel structure material 1 is, for example, about 800 mm, and by incorporating cross brace members between them, the brace members 3 and intermediate members 4 can be used in short lengths, and problems such as the habit of small diameter wood and expansion/contraction can be solved.

Note that the square timber A shown in FIG. 7 is a pillar material 6 in which grooves C are provided on both sides and the panel structural material 1 is used as a wall material. In addition, in order to prevent the occurrence of cracks in each square timber over time, grooves and cuts are made in advance on the square timber.
0 may be entered, and in the case of a groove, a bolt can be passed through. Furthermore, the square timber may be formed by combining two plates back to back.

The panel structure material of this invention has the above-mentioned configuration, and the four peripheral corners of the square timber A made of small-diameter wood are chamfered, and a groove C into which this square fits is provided around the side edge material 2. Then, the brace members 3 and various intermediate materials 4 are processed, and first, both end inclined members 4b are sequentially assembled into the four-sided spaces of the crossed brace members 3 to assemble a square block.

To assemble this block, the intermediate member 4b fitted into the brace member 3 is pressurized from its four peripheries, and the fitting portions of B and C are fixed with adhesive and bolts are also used.

A plurality of blocks as described above are inserted between the side edge members 2, and both end elongated members 4a are installed between the adjacent blocks and between the ends of the side edge members 2, and
Once the fitting portion of the groove C is fixed, the panel structural material 1 as shown in FIG. 1 is assembled.

The above-mentioned panel structural material 1 is used as a wall material or beam material of a wooden building, for example, as shown in FIG. A completely airtight structure and a wall surface with excellent soundproofing effect due to the grooves 5 can be constructed.

Other uses of the panel structural material other than those shown in the drawings include flooring materials, ceiling materials, and the like.

As described above, since this invention has the above configuration, it has the following effects.

(1) Panel structural materials are assembled by combining side edge materials using square timbers, braces, and intermediate materials, resulting in a truss structure with excellent strength, making it possible to use small-diameter wood as structural materials for wooden buildings. This makes it possible to expand the uses of small-diameter wood.

(2) Square timbers can be made into short timbers, making it possible to effectively use small-diameter trees with curls, and also to create vertical, diagonal,
Horizontal combinations can solve the problem of expansion and contraction.

(3) Each joint between the side edge material, bracing, and intermediate material is
Since the panel is sealed by fitting the grooves, the panel becomes a panel with excellent airtightness, and is a building material with excellent cold resistance, wind resistance, fire resistance, sound insulation, and heat insulation effects, and no condensation at all.

(4) Since the corner edges along the length of the square timbers are chamfered, the chamfered portions form grooves when the panel is constructed, and the unevenness of the panel surface greatly improves the soundproofing effect.
