Description

[Detailed explanation of the invention] "Industrial application field" This invention relates to roof framing materials for building houses.

``Prior art'' As shown in Fig. 3, conventional roof frames and roof frame materials are formed by a land beam A, a gassho B, a core bundle C, a support bundle D, a cane E, etc. Manufacturing and assembling the roof required skill and labor, and it had good ventilation and no fire protection. Furthermore, since the corners of the purlin material F contact the gassho B in a linear manner and it is difficult to make them face each other, it is difficult to improve the connection strength.

``Problems to be solved by the invention'' This idea aims to easily manufacture roof framing materials in a factory, simplify the roof assembly work, and obtain strong fireproof roof construction materials at low cost. .

``Means for solving the problem'' This project involves bonding the end faces and top and bottom surfaces of rectangular pieces of wood to form a multi-layered piece of wood, and then gluing each layer of wood to form an integrated layered piece of wood. and the back surface is the straight grain in the longitudinal direction, the upper and lower surfaces are horizontal in the outer layer material, and are inclined in opposite directions toward the roof in the middle layer material, and the upper surface of the layer material is inclined along the roof. In addition, it is constructed of roof frame members with purlin fitting grooves formed on the same sloped surface.

"Operation" Therefore, when building a house, the pillars 11 are erected, the horizontal lower surfaces of the plurality of layered materials 5 are supported on the pillars 11, and the purlins F are fitted into the purlins fitting grooves 8. A plurality of layered materials 5, 5 are connected by the same purlin material F, and the gassho B, B are supported face-to-face on the upper surface of the same purlin material F, and the roof board 7
It forms the In the outer layer materials 2 and 2 of this layered material 5, the upper and lower surfaces of the rectangular timber 1 are horizontal, and the upper and lower surfaces of the middle layer materials 3 and 4 are inclined in opposite directions toward the roof, and the front surface of the rectangular timber 1 is Since the back side is the main eye in the longitudinal direction, it has high strength against forces in the vertical, horizontal, and perpendicular directions to the roof, and is heavy, so the house 7 is stable and the attic space is partitioned off. This prevents the spread of fire. or,
The layered material 5 is formed by gluing together rectangular wooden boards 1 of a fixed size in a factory.

"Example" A large number of relatively thick rectangular pieces of lumber 1 of the same size are manufactured by sawing thinned wood. This sized lumber 1 has a straight grain 6 in the longitudinal direction on the front and back sides. Layer materials 2, 3, and 4 are formed by arranging such rectangular pieces of wood 1 in the same plane in the longitudinal direction and upper and lower directions, and bonding the end surfaces and upper and lower surfaces with an adhesive. It is best to arrange them in a staggered manner in the upper and lower directions. The layer materials 2, 3, and 4 thus constructed are arranged in multiple layers as shown in FIG. 1 and FIG. The roof is tilted in opposite directions in 7 directions. Then, the outer layer materials 2, 2 and the middle layer materials 3, 4 are bonded together with adhesive to form a layered material 5, and the upper surface of the layered material 5 is inclined along the roof 7, and the lower surface is formed horizontally. . Fitting grooves 8 for the ridgepole F' and the purlin material F are cut into the inclined upper surface 5' at predetermined intervals. The fitting groove 8 is a square groove perpendicular to the inclined upper surface 5', and is a square groove for the purlin material F.
The upper surface of the purlin material F is fitted in the same plane as the inclined upper surface 5', and the upper surface of the purlin material F is inclined in the same direction as the direction of the palms B. The lower surfaces of both ends of the layered material 5 are cut out, and the cutout portions 5'' are supported by girders 9. In the figure, 10 is the ceiling surface of the roof.

``Effects'' Since the present invention is constructed as described above, it does not require any skill to manufacture roof framing materials, and it can be easily manufactured in a factory, and the roof assembly work can be carried out easily and quickly. The house has good stability because it has high strength in the direction and is heavy. In addition, the strength of the connection between the gassho and the main building material can be improved, making it possible to safely attach the roof, and by providing a partition wall in the attic, fire safety can also be increased.
