ーチ材２，３に共通の張力をかけ、両アーチ材２，３に
かかる荷重を共通の張弦で吸収させる。As shown in FIG. 1, the string 7 is stretched in a single strip from one end 2a, 3a of the upper and lower laminated arch materials 2, 3 to the other end 2b, 3b, to strengthen the integration of both arch materials 2, 3. A common tension is applied to both arch materials 2 and 3, and the load applied to both arch materials 2 and 3 is absorbed by the common tension.
この場合、張弦７は上部積層アーチ材２の両端のみで固
定しても、その張力を下部積層アーチ材３に及ぼすこと
が可能である。In this case, even if the tension strings 7 are fixed only at both ends of the upper laminated arch material 2, the tension can be applied to the lower laminated arch material 3.
固定位置は例えば下記添柱８を利用して張る場合も含む
ことは勿論である。Of course, the fixed position also includes the case where the support post 8 described below is used for tensioning, for example.
張弦７による張力は各積層板に及ぼされるので該積層板
相互の密着も図り得る。Since tension by the tension string 7 is applied to each laminate, it is possible to ensure close contact between the laminates.

する。Reference numeral 8 denotes a support post considered as an example of a means for fixing the wooden arch truss of the present invention to the foundation pillar 9, and the support post 8 is attached to the upper laminated arch material 2 and the lower laminated arch material 2 when the wooden arch truss is manufactured in a factory or the like. By fixing it to both ends of the arch material 3 in advance, the wooden arch truss of the present invention can be easily erected on the foundation pillars 9 by simply attaching the foundation pillars 9 to the supporting pillars 8 on-site using hardware or tightening bolts and nuts. It has the advantage of being able to

基礎構造体が簡単に構成できる。In addition, when constructing a wooden arch truss with such a structure on-site, the eave girders 10 are installed horizontally on the foundation columns 9 of the wooden building, and then a plurality of wooden arch trusses are simply installed at regular intervals in a state perpendicular to the eave girders 10. The foundation structure of the roof can be easily constructed by installing them side by side and fixing them to each foundation column and eave girder.
次で、上部積層アーチ材２の上面に母屋たるきを介し長

く貢献できる。Therefore, in this invention, the upper and lower arch materials are formed by laminating and polymerizing an appropriate number of plate materials to form a double arch structure, so compared to, for example, an arch truss in which laminated materials are stretched in an arch shape on a conventional square beam. However, the double laminated structure significantly increases the strength of the roof assembly structure, making it excellent in robustness against earthquakes, snowfall, typhoons, etc.
Because it does not use beam materials, it can greatly contribute to reducing construction costs at a time when lumber prices are soaring.
下部積層アーチ材を用いることで天井が高くとれ、内部
空間を有効に利用することが可能である。By using laminated arch materials at the bottom, the ceiling can be raised high and the interior space can be used effectively.

費を大巾に削減できる。In particular, in this invention, the arch truss is constructed with a double laminate structure of the upper laminated arch material and the lower laminated arch material, so it is possible to construct a roof assembly with sufficient strength by arranging a small number of arch trusses in parallel. The roof assembly can be simplified and lightened, and construction costs can be significantly reduced.

る。Furthermore, in addition to the above-mentioned double laminate structure, the present invention has a structure in which at least one end of the upper laminate arch member and the other end of the upper laminate arch member are pulled by tensioned strings from wires, pipes, etc., so that it is resistant to vertical loads or lateral external forces. It has the effect of absorbing the load and distributing it evenly to the double arch truss, and in addition, it has the advantage of further improving the durability of the double arch truss and enhancing the arch shape retention of the double arch truss. .
