Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dome roof construction structure and a dome roof construction method using the same.

[0002]

2. Description of the Related Art FIGS. 3 to 5 (FIG. 5 is a view as seen from an arrow C in FIG. 3).
FIG. 4 is an explanatory view conceptually showing a dome roof assembly structure according to a conventional technique. As shown in these drawings, the dome roof assembly structure according to the related art is constructed by a steel truss structure 8.

[0003]

The roof assembling structure of the steel truss structure 8 according to the prior art as described above has a complicated structure and many materials, and because the work is carried out at high places by the scaffolding construction method,
There is a problem that the risk is high and the work time is long.

In view of the above prior art, it is an object of the present invention to provide a dome roof construction structure which has a simple structure and can be constructed quickly and safely and a dome roof construction method using the same.

[0005]

[Means for Solving the Problems] First to achieve the above object
The configuration of the invention of, a plurality of bending members that are bent and formed in an arch shape and are radially arranged so as to overlap at the central portion,
A tension member in which the upper end is attached to the center of the bent member and hangs vertically downward and the lower end is attached to the hub-shaped connecting member,
One end is attached to each of the bending members at two points in the middle thereof and extends in the horizontal direction, and the other end is provided with a compression member attached to each of the connecting members.

According to the second aspect of the invention, a step of radially arranging a plurality of arched bending members so as to overlap each other in the central portion, and attaching an upper end of the tension member to the central portion of the bending material Attaching the lower end to the hub-shaped connecting member,
Attaching one end of each compression member to two points in the middle of each bending member, and attaching the other end of each compression member that extends horizontally to each connecting member, and covering the space between adjacent bending members with a film member. And a step of stretching the film material by applying a tensile force.

[0007]

According to the first and second aspects of the present invention, the bending material serving as the main frame is formed into a dome shape in a radial shape, and is fixed only by a tension material and a compression material from its center, so that the structure is simple and aesthetically pleasing. In addition, the cost can be reduced and the work in high places can be reduced to improve the safety, and the number of steps can be significantly reduced as compared with the conventional one.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a view of the roof building structure according to the present embodiment as seen from the direction of arrow A in FIG. 2, and FIG. 2 is a view taken along the line BB thereof.

As shown in both figures, the plurality of bending members 1 are
It is bent into an arch shape and is radially arranged so as to overlap at the central portion (the center of the roof), and both lower ends of each bending member 1 abut on the foundation structure 2 and stand on the foundation structure 2. I am doing it. The tension member 3 has its upper end attached to the center of the bending member 1 and hangs vertically downward, and its lower end attached to the hub-shaped connecting member 4. One end of each compression member 5 is attached to each of the bending members 1 at two positions along the horizontal direction to extend in the horizontal direction, and the other end is attached to each connecting member 4. Thus, the connecting member 4 located below the center of the dome roof
A compression member 5 whose base end is attached to this connecting member 4
Have a structure in which they radially project horizontally toward the bending material 1 and the respective tip portions are attached to two points in the middle of each bending material 1. The membrane member 6 is attached between the bending members 1 so as to cover the adjacent bending members 1, and the roof structure can be stabilized by applying a tensile force.

If necessary, the lower portion of the bending material 1 is fixed by a wire 7 depending on the load conditions and the scale of the dome.
This wire 7 has one end fixed to the substructure 2 and the other end fixed to the lower part of each bending member 1. In such a dome roof assembly structure, a plurality of bending members 1 are radially arranged, a tension member 3 is installed between the bending member 1 and a connecting member 4 vertically below the central portion of the bending member 1, and the bending member 1 is horizontally arranged from the connecting member 4. It is constructed by arranging the compression members 2 radially in the direction and fixing the compression members 2 to each bending member 1. The membrane material 6 is attached to the roof construction structure in such a state.

According to the present embodiment, as compared with the steel truss structure 8 according to the prior art, the scaffold construction method is completely changed, and the work at a high place by the ground assembly and the lifting construction method is significantly reduced to improve the safety. The time required for construction work can be significantly reduced as well as improved.

[0013]

As described above in detail with reference to the embodiments, according to the present invention, the structure of the frame can be greatly simplified as compared with the conventional structure, and the cost can be reduced accordingly. And work at heights can be significantly reduced,
As a result, safety is greatly improved.
