2. Description of the Related Art As a structural member formed by stretching a tensile member such as a steel wire or a steel bar on a frame member such as a steel frame, there is a column 50 as shown in FIG. The pillar 50 includes one continuous frame member 51, horizontal members 52, 52 connected to the frame member 51 so as to be orthogonal to each other at a predetermined interval, and an upper end 51 of the frame member 51.
a from the lower end 51b to four horizontal tension members 53, which are fixedly attached to the tips of the horizontal members 52, 52. This pillar 5
At 0, the buckling of the frame member 51 is prevented by the tension of the tension member 53, so that the frame member 51 can be made thin.

[0003]

In the column 50, since the frame members 51 are vertically continuous, the visual continuity is conscious thereof, and the entire column 50 appears to be a structural column for supporting a load. . For this reason, the column 50 cannot be used in a place where a member having a load supporting capacity is required structurally and where the structural column is required to be omitted in terms of design.

The present invention focuses on the above-mentioned problems of the prior art,
The challenge was to give the observer a visual discontinuity, a sense of design floating,
Another object of the present invention is to provide a structural member having a load supporting ability.

[0005]

In order to solve the above-mentioned problems, in the present invention, two triangular frames are connected to each other, and a predetermined angle of each frame is arranged at both ends so as to be separated from each other. A three-dimensional unit is formed by stretching a tension member between the corners of the three-dimensional frame, a plurality of the three-dimensional units are arranged substantially linearly, connected at the corners of each end, and a predetermined space between the adjacent three-dimensional units is determined. To provide a skeleton structure characterized in that a tension member is stretched over the skeleton structure.

In the frame structure of the present invention, the triangular frame is formed by connecting shaft members so as to form three sides of the triangle, and a plate or other member is provided inside the frame member surrounded by the shaft members. Preferably, no shaft member is provided. Further, the two frames forming the three-dimensional unit are connected so as not to be connected and fixed to the shaft member of another frame. In the two triangular frames linked together, it is preferable that each predetermined side is arranged to be substantially parallel to each other and separated from each other by a predetermined length, and further, each apex angle with respect to each side is separated from each other at both ends. Place and tension members between each corner of both frames to maintain these placements.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments. FIG. 1 is a perspective view of a pillar as one example of a frame structure of the present invention, and FIG. 2 (a) is a front view of the pillar of FIG. 2) is a side view of the column in FIG. FIG. 3 is a perspective view of the three-dimensional unit constituting the pillars of FIGS. 1 and 4, wherein FIG. 3A is a perspective view, FIG. 3B is a horizontal front view from FIG. Is a side view.

In FIG. 1, a pillar 1 is shown in FIGS.
Three three-dimensional units 10 as shown in (c) are arranged substantially linearly in the vertical direction, and the three-dimensional units 10 and 10 adjacent to each other are arranged.
Are connected at their apex angles 25 and 15, and the corners 16a, 16b, 26a, 26b
It is formed by stretching a tension member 18 therebetween. Here, the connection between the adjacent three-dimensional units 10, 10 is performed by a conventional ball joint (not shown) or a cast steel joint (not shown), or via a plate member 40 as shown in FIG. To join.

The pillar 1 has an upper end connected to a ceiling 2, a roof frame (not shown) or a main frame (not shown) via a hinge (not shown), and a lower end thereof to a floor slab 3, It is connected to a foundation beam (not shown) or a main frame via a hinge. Also, in FIG. 1, the three-dimensional units 10, 10 which are vertically adjacent to each other are connected in the same direction. However, as shown in FIG. 4, every other three-dimensional unit 10 is rotated by 90 ° in the assembling direction. May be connected.

In each of the three-dimensional units 10, the two triangular frames 11 and 21 are connected in a ring, and a tension member 17 is stretched between the corners of the triangular frames 11 and 21. More specifically, the triangular frame 11 includes three main members 12, 13, 14 such as a steel frame and a steel pipe so as to form three sides of a triangle.
And the triangular frame 21 is formed in the same manner.
The inside of the triangular frame 11 surrounded by the main members 12, 13, and 14 is not provided with a plate or a shaft member as a reinforcing material, and is passed through the main member 24 of the triangular frame 21, and the triangular frame 11, The main members 21 are connected so as not to be connected and fixed to each other. The linked triangular frame members 11 and 21 are arranged such that the main members 14 and 24 are spaced apart from each other by a predetermined length and are substantially parallel to each other, and the apex angles 15 and 25 are spaced apart from each other at both ends. Then, a tension member 17 is stretched so as to maintain the arrangement of the triangular frames 11 and 21. That is, from the base angles 16a and 16b of the triangular frame 11, tension members 17 are respectively stretched to the base angles 26a and 26b and the vertex 25 of the triangular frame 21 and the vertex angle 15 of the triangular frame 11 is further extended. Thereafter, the tension members 17 are stretched at the base angles 26a and 26b of the triangular frame 21 respectively.

Next, the operation of the column 1 in which a plurality of the three-dimensional units 10 are provided will be described. The load on the ceiling 2 acts from the top angle 15 of the topmost three-dimensional unit 10,
The axial force is transmitted to the main members 12, 13, 14 of the triangular frame 11, acts as tension from the main members 12, 13, 14 to the tension member 17, and further, the main members 22, 2 of the triangular frame 21.
3 and 24 to the apex angle 25. Then, from the apex angle 25, the light is transmitted to the apex angle 15 of the three-dimensional unit 10 therebelow, and similarly transmitted downward.

In the column 1, the adjacent three-dimensional units 10 are connected to each other at the apex angles 15, 25 of the triangular frames 21, 11, so that the three-dimensional units 10 are visually vulnerable to the observer, ie, each three-dimensional unit. In combination with the connecting ring of the units 10, a design floating feeling is given, but at the same time, the tension of the four tension members 18 is acting between the three-dimensional units 10, and this tension restrains the bending of the entire column, and Since bending rigidity and stability are provided, buckling between adjacent three-dimensional units 10 is prevented, and the column 1 can have a sufficient load supporting capacity.

[0013]

According to the skeleton structure of the present invention, a three-dimensional unit is formed by fixing two triangular frames by a tension of a tension member in a continuous ring state in which the respective frame members do not contact each other. The framing material becomes discontinuous at the connecting portion of the framing, and can give the observer a visual discontinuity, that is, a design-like floating feeling. In addition, since the load can be transmitted and supported by the tensile member between the visually discontinuous triangular frames, the frame structure can also have a load supporting ability. In addition, since a tension member is stretched between adjacent three-dimensional units, the frame structure does not buckle due to the tension of the tension member,
Sufficient load supporting ability can be exhibited.
