構成は波トラスであつて一方向に荷重を伝えるこ
とはできるが立体トラスではない。 By the way, a truss was developed in which the upper and lower chord members are connected by a belly member to form a unit frame member, the unit frame members are arranged in a zigzag pattern, and the upper and lower chord members are arranged orthogonally. Its contents have been disclosed. The unit frame materials for this truss can be mass-produced in a factory, and assembly work is easy. However, although its configuration is a wave truss and can transmit loads in one direction, it is not a space truss.
そこでこの発明は前記開示されたトラスを発展
させて立体トラスを構成するようにしたものであ
る。 Therefore, the present invention is an improvement of the above-disclosed truss to form a three-dimensional truss.

成としてある立体トラスである。Structure of the Invention The present invention comprises a unit frame member in which an upper chord member and a lower chord member which are parallel to each other at a constant interval are connected with a belly member which slopes in a zigzag shape when viewed from one side. Arrange multiple pieces in parallel so that the belly members are inclined in a zigzag shape when viewed from the other side, and also connect adjacent upper and lower chord members to determine the position of the upper and lower chord members at the intersection of the belly members. This is a three-dimensional truss in which an upper chord member and a lower chord member are arranged orthogonal to the upper side of the upper chord member and the lower side of the lower chord member and are connected to each other.

ジを重ねた状態で結合される。 In addition, at the position of the upper chord member and the lower chord member that are the intersection points of the belly members 3, the upper chord member 11 or cut T is made by placing two angle irons back to back, orthogonal to the upper side of the upper chord member and the lower side of the lower chord member. An upper chord member and a lower chord member 12 are arranged and connected by bolts, nuts, rivets, etc. At this time, each chord member is joined with its horizontal flanges overlapped.

いては部材数および重量を減少できる。Effects of the Invention This invention has the above-mentioned configuration, and is a combination of a unit frame material and upper and lower chord members perpendicular to the upper and lower chord members of the unit frame material, and by mass producing the unit frame materials, it is possible to save labor in assembling on site. , efficiency can be achieved. In addition, in the conventional example, the upper and lower chord members in one direction do not pass through the nodes of the belly member and the upper and lower chord members, so they do not constitute a three-dimensional truss, whereas in the present invention, the other upper and lower chord members pass through the nodes of the unit frame members, By constructing a three-dimensional truss, the structural strength can be improved, and the number of members and weight can be reduced.
