組立方法に問題を生ずることが屡々ある。Compared to buildings that require large spaces such as gymnasiums and music halls, they require a three-dimensional structure, and are often constructed using a three-dimensional truss on one side of the three-dimensional structure. However, conventional space trusses have many nodes where members are concentrated three-dimensionally, which often causes problems in their construction and assembly methods.

少し、製作、施工の簡易をもたらすことに成功した。By the way, in this invention, the entire frame is a three-dimensional frame, but each part of the frame is a 17-sided truss, and in particular, by connecting the main members in the direction with stepped truss beams, it is possible to create a three-dimensional structure. We succeeded in reducing the number of members and joints compared to a truss, simplifying manufacturing and construction.

ることかできる。1 to 4 show an example of a building having a rectangular plane, in which the main member 1 is placed at the twill line position of a square pyramid. This main member 1 transmits the load applied to the frame to the lower frame, for example a column or a V, l::X foundation. The truss beams 2 are parallel to one side of the rectangle, and are arranged in multiple rows in a stepped manner between the main members 1 and in accordance with the slope of the main phase 1. The upper chord members and lower chord members of each adjacent truss beam 2 are alternately connected diagonally by horizontal members 3 to form a truss shape. The truss beam 2 transmits the load of the roof surface to the main member 1 and restrains the main member 1 to produce a three-dimensional effect. When a fixed load is applied, as shown in Fig. 5, the truss beam 2 with a large span near the base exerts a tensile force that restrains the spread of the main member 1.
)・The bending deformation of the truss beam 2 can be reduced, and the beam deflection of the truss beam 2 can be reduced. In addition, the horizontal rigidity of the entire frame can be increased by 1t'6 by the horizontal part arranged in a truss shape, and the 4711i seat J11 of the truss beam 2 can be set by 1.

The main member 1 and the two L/lath beams are connected to each other through a gusset plate 7, and the lattice 6, upper and lower chord members 5, and the upper and lower chord members 5 and the horizontal member 3 are connected through a gusset plate 7, respectively.

減少できる。This invention consists of the above-mentioned structure, and the main member, truss beam, and horizontal member are all configured in a plane, and because of them,
Since the width can be made the same, there are no three-dimensional joints, and there are few component parts, it is easy to fabricate a steel frame, making it suitable for mass production.In addition, it is easy to construct on-site because there are fewer pieces to assemble and fewer joints. 1. The main material that forms the main frame is restrained by truss beams arranged in a stepped manner, so it can be supported by rollers in the Y-bin or twill direction, and the lower structure It has a small impact on the environment, and the foundation structure or substructure can be simplified. On the other hand, in a truss beam, the tensile force that restrains the main member acts and reduces deflection, so the beam height can be reduced and the steel thickness can be reduced.

Furthermore, it is easy to suspend the floor structure from the truss beams arranged in a stair-like manner, and it is possible to easily create a single landing or room with a view of a large space. .
