Description

[Detailed Description of the Invention] This invention relates to a structural material used as walls, beams, and flooring materials of wooden buildings, and more specifically, to a panel structural material 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 expensive and takes a long time, so improvements are strongly desired.

In addition, in the production of lumber, the treatment of small-diameter wood such as thinned wood is becoming a serious problem nationwide, and expanding the use of small-diameter wood has become an urgent issue.

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.

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

The structure of this invention is to use square timbers for each of the side edge materials arranged in parallel on both sides, the horizontal beams installed between the side edge materials, and the plate that is incorporated in the area surrounded by the side edge materials and the horizontal beams. It is formed by stacking a plurality of individual plates in which the square pieces are successively connected in parallel by fitting the handle and the handle groove so that the lengthwise direction of the square pieces is arranged in a cross-like manner.

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

As shown in the figure, the panel structural material 1 includes a pair of side edge members 2 arranged in parallel on both sides, a horizontal crosspiece 3 installed between the both side edge members 2, and a portion surrounded by the both side edge members 2 and the horizontal crosspiece 3. It is composed of a plate 4 to be incorporated into the side edge material 2,
Each of the horizontal beam 3 and the plate 4 is formed using a small diameter wooden square.

The side edge material 2 and the horizontal bar 3 are made of a square material with a cross-sectional shape having a handle 5 on one side and a handle groove 6 on the other side, and the horizontal bar 3 has a handle 5 also processed at the end and is arranged in parallel It is assembled into a frame by constructing horizontal beams 3 at both ends and in the middle between the side edge members 2.

In the illustrated case, three horizontal bars 3 are assembled in the intermediate portion by fitting the handle 5 and the handle groove 6 and connecting them in parallel.

The plate 4 is constructed using a split square piece 7 that is obtained by cutting the square piece used for the side edge material 2 and the horizontal beam 3 into one third along the longitudinal direction.

As shown in FIG. 3, the split square material 7 has a handle 7a at one end located in the longitudinal direction of the cross section and a handle groove 7b at the other end, and is chamfered 8 at the corner of one wide side along the longitudinal direction of the cross section. By sequentially fitting the handle 7a and the handle groove 7b and connecting them in parallel, a flat single plate 9 is assembled.

The plate 4 is formed by stacking the three single plates 9 described above.

As shown in FIGS. 1 and 3, the two plates 9 are combined so that the longitudinal directions of the split pieces 7 intersect in order at right angles, and the plates 4 and the side edge pieces 2 It is formed in a size that fits within a rectangular space surrounded by horizontal bars 3.

In the illustrated case, the plate 4 is processed so that the longitudinal direction of the split square material 7 is parallel or perpendicular to the longitudinal direction of the side edge material 2, and the outer peripheral edge thereof has a handle groove 6. A fitting handle 10 is provided, and grooves 11 are formed by chamfering 8 on both sides.

In addition, the fitting portions of the side edge material 2 and the horizontal bar 3, the handles 5 and 10 of the plate 4, and the handle groove 6, the overlapping surfaces of the plate unit 9 forming the plate 4, and the fitting portions of the handle 7a and the handle groove 7b. may be fixed with adhesive, and may be connected with bolts or the like at necessary locations.

FIG. 4 shows the joint structure of the side edge material 2 and the horizontal crosspiece 3 using bolts, and shows the horizontal hole 12 of the side edge material 2 and the horizontal crosspiece 3.
The bolt 14 is inserted along the through hole 13 along the longitudinal direction of the bolt 14.
is inserted and tightened with nuts from both sides.

The combination of each unit 9 in the plate 4 is as follows:
The split square timbers 7 may be processed so that the longitudinal direction thereof is inclined with respect to the vertical direction, and the split square timbers 7 are preferably assembled so that the direction of the wood grain is reversed.

The square materials used for the side edge materials 2 and the horizontal beams 3 are pre-formed with cuts and grooves 15 in order to prevent cracks from occurring over time.
In the case of a groove, it can be used for inserting a bolt.

The panel structural material 1 shown in Fig. 1 is used as a wall material of a building, and both side edge materials 2
Three sets of plates 4 are installed between them.
As shown in FIG. 7, the length can be freely selected depending on the purpose, such as incorporating two sets of plates and using it as a shortened beam structural material.

The width of the panel structure material 1 is, for example, about 800 mm, and by incorporating the horizontal beams 3 and plates 4 between them, it is possible to use short square timbers, and problems such as curling and expansion/contraction of small-diameter wood can be solved.

The square timber shown in FIG. 6 has handle grooves 6 on both sides and is used as a column 16 when the panel structural material 1 is used as a wall material.

The structural material of this invention has the above structure,
A plate 4 is a combination of a side edge material 2, a horizontal bar 3, and a split corner material 7, which are made of a square material made of small-diameter wood and provided with a handle 5 and a handle groove 6.
By sequentially assembling and processing from the four peripheral edges, the fitting parts of the handles 5 and 10 and the handle groove 6 are fixed with adhesive, and by using bolts etc.
A panel structure material 1 as shown in the figure 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 wall surface with a completely airtight structure and excellent soundproofing effect due to the grooves 11 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) The panel structure material is assembled by combining the side edge material using square lumber, intermediate material, and plate, so it has excellent strength, and it is possible to use small-diameter wood as structural material for wooden buildings. It is possible to expand the range of uses.

(2) Since square timbers can be shortened and used, curly small-diameter wood can be used effectively, and the problem of expansion and contraction can be solved by combining vertical and horizontal plates.

(3) Each joint between the side edge material, intermediate material, and plate is sealed by fitting the handle and handle groove, resulting in a panel with excellent airtightness, cold resistance, wind resistance, fire resistance, sound insulation, and heat insulation effects. It has excellent properties and becomes a building material that does not generate any condensation.

(4) When the corner edges along the length of the square timber are chamfered, the chamfered parts will form grooves during panel construction, and the unevenness of the panel surface will greatly improve the soundproofing effect.
