BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional structure used in gymnasiums, hangars and the like.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Publication No.
A rhombic network skeleton structure described in Japanese Patent No. 6328 is known.

In this three-dimensional structure, equidistant intervals are formed so that a lozenge mesh can be formed by the roof skeleton on each gable side edge (gable portion) and each roof side edge (side portion) of the roof portion forming the gabled surface arch. Each division point is provided. The side pillar supporting the roof side edge and the end of each chord member (frame member) forming the roof frame are V
Shaped gusset plates are used for joining. Further, the intersection of the gauge line of the chord member and the center line of the side pillar is provided so as to be displaced toward the axial center side of the side pillar from the gusset plate mounting surface of the side pillar, and the gusset plate is provided at the axial center of the side pillar. The load acting on the roof portion is processed through the gusset plate so that the gusset plate does not cause problems such as buckling. Further, the intersections and the ridge center of the roof portion are equally divided to provide unit frame bodies, and the roof skeleton can be assembled and constructed sequentially from the roof side edge side toward the ridge center of the roof portion. I am trying.

However, in the above-mentioned conventional three-dimensional structure, it is necessary to attach the V-shaped gusset plate to the side pillar. Therefore, as the simplest method, it is considered that one plate is bent to manufacture a V-shaped gusset plate, and the bent base portion of the gusset plate is brought into contact with the surface of the side pillar to perform welding. However, in this case, it is not possible to weld from the valley side of the bent base portion, and there is no choice but to weld from both outsides of the gusset plate, and moreover, the gap between the gusset plate and the side column is narrow and sufficient penetration is not possible. Since it is not obtained and the welding strength is insufficient, the V-shaped gusset plate cannot be firmly provided on the side pillar.

Therefore, as shown in FIGS. 8 and 9 of Japanese Patent Publication No. 54-16328, two plate members formed in a dogleg shape are used, and one of both plate members is used. One piece was stacked so that the other piece faced in the opposite direction, and the other piece formed a V shape to form one gusset plate.

However, in the above conventional three-dimensional structure, in order to attach the gusset plate to the upper part of the side pillar,
Two supporting rods that extend upward are formed facing the upper ends of the side columns, and one side portion of the gusset plate is engaged between the supporting rods and fastened with a bolt or the like. It is necessary to join between this and the supporting rod by a joining plate. As described above, the configuration of the gusset plate that joins the side portion of the roof portion and the upper portion of the side pillar is complicated, and since the number of used members is large, the gusset plate cannot be easily installed. As a result, there is a problem that the construction cost of the jointed three-dimensional structure is increased in combination with many joints between the roof portion and the side pillars.

The present invention has been made to solve the above problems, and an object thereof is to easily manufacture a gusset plate in the above-mentioned three-dimensional structure with a small number of members, and further, to provide a joint strength between the gusset plate and the side pillar. Is to be able to secure enough.

[0008]

In order to achieve the above object, the present invention comprises a side pillar for supporting a side portion of the roof portion by constructing a roof portion by assembling a plurality of frame members in a mesh shape. While joining the end of the frame member via a gusset plate, the intersection of the gauge line of the frame member and the center line of the side column is shifted to the axial center side of the side column from the gusset plate mounting surface of the side column. In the three-dimensional structure provided as described above, the gusset plate is composed of a pair of mounting plates in the shape of a V to which the ends of the frame members are joined, and one end of each of the mounting plates on the side column side is It is mounted on the gusset plate mounting surface of the side pillars while being separated from each other.

[0009]

According to the above construction, when assembling and constructing a three-dimensional structure, first, a sufficient gap is secured between the pair of mounting plates so that the mounting plates come into contact with the side columns, After the gusset plate is installed by firmly attaching the both mounting plates to each other by welding using the gap, the side pillar is planted, and the end portion of the frame member is joined to the side pillar through the gusset plate. To do.

Further, in the above three-dimensional structure, the intersection of the gauge line of the frame member and the center line of the side pillar is provided so as to be displaced from the gusset plate mounting surface of the side pillar to the axial center side of the side pillar. A load acting on the roof portion is processed through the gusset plate on the axis of the side pillar.

8 ₂ was bonded to the side 23a of the roof 23 via the gusset plate be composed of, it can also be applied to split the side post 11 as in the third embodiment. When the side pillar 11 is composed of a lower side pillar 11a to be planted in the foundation 2 and an upper side pillar 11b joined to the lower side pillar 11a, the upper side pillar 1
Since 1b is joined to the side portion 3a of the roof portion 3 in advance, on-site construction becomes easier than in the cases of the first and second embodiments.

[0028]

As described above, according to the present invention, a plurality of frame members are assembled in a mesh shape to form a roof part, and side pillars for supporting the side parts of the roof part and the end parts of the frame members are formed. While joining through a gusset plate, in the three-dimensional structure provided by shifting the intersection of the gauge line of the frame member and the center line of the side column to the axial center side of the side column from the gusset plate mounting surface of the side column, The gusset plate is composed of a pair of V-shaped mounting plates to which the end portions of the frame members are joined, and one end of each of the mounting plates on the side column side is separated from each other so that the gusset of the side column is formed. Since it was mounted on the plate mounting surface, a sufficient gap was secured between the pair of mounting plates so that both mounting plates abut on the side pillars, and the both mounting plates are welded to the side pillars by utilizing the gaps. Can be firmly attached. Therefore, since the gusset plate can be easily manufactured with a smaller number of members as compared with the conventional case, the manufacturing efficiency can be improved and the cost can be reduced.

Further, since the intersection of the gauge line of the frame member and the center line of the side pillar is provided so as to be displaced from the gusset plate mounting surface of the side pillar toward the shaft center side of the side pillar, The load acting on the roof through the gusset plate can be smoothly processed. Therefore, it is possible to prevent the gusset plate from buckling or cracking due to external force such as seismic force, wind force, uneven load such as snow, as in the conventional case.
