A variety of three-dimensional truss structures (space frames), which are constructed by three-dimensionally assembling body parts, etc.) and ball joints using connectors, have been developed in the past, but the main one is the so-called melo truss, and Ganto Toyama also developed a unit truss. We have developed a unique three-dimensional truss.
ところで、この種の立体トラス構造物に、たとえば屋根

、建設コストも割高になる。However, in such a structure, it is necessary to install the purlin support member on top of the upper chord of the truss structure, and the purlin support also requires fittings for fixing the member, so the number of parts and joints are significantly increased. Not only will the increase in construction lead to a longer construction period, but the construction cost will also be higher.

構築する。During construction, the unit body of the three-dimensional truss structure is assembled to a thickness that can be transported by lifting waves by attaching purlin materials or ceiling support materials to the upper or lower chord members of the three-dimensional truss structure on the ground. A large-scale three-dimensional truss structure is constructed by lifting a plurality of the units to the installation location using a lifting machine and then joining the units together.
また、必要な場合には、各ユニット体の下側に吊り作業
足場を設置しておけば、ユニット体の設置と同時に作業
足場も設置することができる。Further, if necessary, by installing a suspended work scaffold below each unit body, the work scaffold can be installed at the same time as the unit body is installed.
この発明は以上の構成からなるので以下の効果を有する

定金具が一切不要になり、部材数の節約及び作業の省略
化が図れる。Since shaped steel is used for the upper chord member or lower chord member that constitutes the three-dimensional truss structure, the purlin member or ceiling support member can be directly attached to this member. Therefore, since the upper chord material and the purlin support also serve as the material, the conventional upper chord material in one direction is no longer necessary, and the material for the purlin support and the fixing fittings to fix it are no longer necessary, which saves on the number of parts. And the work can be simplified.

れる。In addition, during construction, the unit body of the three-dimensional truss structure is assembled to an appropriate size by attaching purlin materials or ceiling support materials to the upper or lower chord members of the three-dimensional truss structure on the ground, and the unit is lifted up. Since the three-dimensional truss structure is constructed by lifting it to the installation site using heavy machinery and joining the units together, construction efficiency is extremely high, and construction time and construction costs can be significantly reduced.
