Abstract

PURPOSE:To provide an optional dome space and an optional outer peripheral part of ready-made unit rings by arranging a large number of the unit rings with curved face plates set on central through hole parts of ring parts on a dome roof face and simultaneously joining the ring parts of the adjacent unit rings with each other. CONSTITUTION:By arranging a curved face plate 3 on a circular or polygonal through hole part provided in the center of a ring part 1, a unit ring A is formed. Thereafter, this unit ring A is arranged on a dome roof face. Thereafter, it is joined through a joint part consisting of a mortice type U bolt and others provided on the ring part 1 of the adjacent ring A. Thereafter, in a circular arc recessed curved face space of four pieces of the adjacent unit rings A, a circular plate 6 is fit. Consequently, by constructing a dome roof by way of combining the ready-made unit rings A, it is possible to improve workability and working precision.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dome structure applied to a multipurpose facility such as an event hall and a stadium.

[0002]

2. Description of the Related Art A conventional structure of this type is constructed by assembling a dome frame, casting concrete on site and applying a roof finishing material to the frame.

[0003]

The above-mentioned conventional dome structure is complicated in construction and requires a lot of labor, and it is difficult to construct a dome roof structure having a desired shape. The present invention has been proposed in view of such circumstances, and an object thereof is to provide a dome structure having a composite structure in which an arbitrary dome space can be obtained by using a ready-made unit ring.

[0004]

In order to achieve the above object, the dome structure according to the present invention has a plurality of unit rings, each having a curved plate set in the central through hole of the ring, arranged on the dome roof surface. In addition to being installed, the ring portions of adjacent unit rings are joined together.

[0005]

According to the present invention, as described above, the unit ring is constructed by setting the curved plate in the through hole provided in the center of the ring portion, and the thus formed multiple unit rings are arranged on the dome roof surface. It is possible to easily form a dome roof surface having a required shape, which is made of a required material, by connecting the adjacent unit rings to each other by setting the size and the number of the unit rings. An arbitrary space can be constructed by freely selecting a combination.

[0006]

The present invention will be described below with reference to the illustrated embodiments. A is a unit ring, which is provided in the center of the ring portion 1 and is provided with a curved plate 3 or a flat plate in a circular or polygonal through hole portion 2. Further, the through hole portion 2 may be filled with a structural material.

The plane shape of the unit ring A is circular,
It is a polygon, and the size of the plane depends on the use of the facility and the scale of the dome.
Is composed of a precast concrete single panel, a metal single panel, a plastic panel, a laminated wood panel, etc. as shown in FIG. 5 (a), or a hollow rib precast concrete panel as shown in FIG. 5 (b), or FIG.
As shown in (c) and FIG. 5 (d), the precast concrete panel 1b or the metal plate 1c is attached to the metal frame 1a. Further, arcuate concave curved surfaces 4 are formed at four corners of the ring portion 1.

The curved plate 3 is made of transparent or translucent glass, synthetic resin plate, metal plate or the like. Thus, the unit ring A is arranged on the roof surface of the dome, and the ring portions 1 of the adjacent unit rings A are provided on the same portion 1 through the joint portion 5 formed by a tenon, mortise type, U bolt, or the like. Curved surface plate 3 in a circular space formed between the arcuate concave curved surfaces 4 of four unit rings A adjacent to each other.
Similarly, a transparent or translucent glass or synthetic resin plate or a circular plate 6 made of a metal plate is fitted. The ring portion 1 may be joined by using welding or an adhesive instead of the joining portion 5.

In principle, the ceiling should not be stretched,
A ceiling material as a non-structural material may be stretched. B in the figure
Is the foundation of the dome structure, C is the floor, D is the wall, E is the auditorium,
F is a peripheral lower structure, and 7 is a wall of the peripheral lower structure.
Since the illustrated embodiment is configured as described above, the dome structure can be constructed by combining the ready-made unit rings A, and the size and number of the unit rings should be appropriately selected. By this, any dome space can be configured.

[0010]

As described above, according to the present invention, a large number of unit rings each having a curved plate set at the center of the ring portion are arranged on the dome roof surface, and the ring portions of adjacent unit rings are mutually connected. Since the dome is constructed by joining the spaces, it is possible to construct a dome roof by combining ready-made unit rings, which improves the workability and the construction accuracy.

Further, an appropriate dome space can be constructed by appropriately selecting the combination of the size and number of the unit rings. Still further according to the invention,
As the unit ring material, it is possible to use almost all materials currently used as building materials.
