Description

DETAILED DESCRIPTION OF THE INVENTION <<Industrial Application Field>> The present invention relates to a dome-shaped roof structure, and more particularly to a dome-shaped roof structure that can be attached or detached depending on the weather.

<<Prior Art and Problems>> As is well known, structures for athletic events such as baseball stadiums and track and field stadiums do not have roofs.

This is intended to allow athletic competitions to be held in as natural a environment as possible, but if it rains or it rains during a competition, the competition must be suspended or canceled.

Therefore, all-weather stadiums have recently been proposed, and for example, air membrane structures are attracting attention.

However, the air membrane structure has the following problems.

In other words, in an air membrane structure, the roof is made of a membrane material made of synthetic resin, etc., and pressurized air that is slightly higher than atmospheric pressure is sealed inside. In order to prevent leakage, the entrance/exit structure becomes complicated.

Furthermore, not only does lighting and ventilation inside the stadium become difficult, but the original purpose of the competition is lost if the competition is held or watched in a natural environment.

<<Purpose of the Invention>> This invention has been made in view of the above-mentioned problems of the conventional technology.The present invention is made in view of the above-mentioned problems of the conventional technology. To provide a dome-shaped roof structure that allows competitions to be held and also in rainy weather.

<<Structure of the Invention>> In order to achieve the above object, the present invention provides a structure comprising a side wall part erected on the ground and a dome-shaped roof member whose periphery is fixed to the side wall part, in which the roof member is , which can be expanded and contracted like an umbrella, and is removably attached to a telescopic support, and is stored underground together with the support in the contracted state, and is separated from the support in the expanded state and attached to the side wall. It is characterized by being removably locked to the section.

Further, the present invention provides a structure comprising a side wall erected on the ground and a dome-shaped roof member whose peripheral edge is fixed to the side wall. A ring-shaped eave is fixedly attached to the roof member, and the roof member can be expanded and contracted like an umbrella, and is removably attached to a telescopic column, and in the contracted state, it can be placed underground together with the column. It is characterized in that it is stored and separated from the pillar in an expanded state, and its outer peripheral edge is removably locked to the eaves so as to cover the central opening of the eaves.

<<Example>> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figures 1 to 4 show an embodiment of the dome-shaped roof structure according to the present invention, with Figure 1 showing how it is used in sunny weather, and Figure 2 showing how it is used in rainy weather. ing.

The dome-shaped roof structure shown in the figure is applied to an athletic stadium consisting of a cylindrical side wall part 10 that stands on the ground and has an open top end, and a dome-shaped roof part 12 that covers the top opening. Inside the side wall portion 10 is a stand 1 for accommodating spectators.
4 is provided.

The roof portion 12 is formed into a ring shape by combining reinforcing bars in a truss shape, has an outer peripheral edge fixed to the upper end of the side wall portion 10, and has an eaves 16 extending inward and a central opening of the eaves 16. It is comprised of a roof member 18 that expands like an umbrella to cover the inner peripheral edge of the central opening and removably locks the outer peripheral edge.

The roof member 18 includes a frame 18a and a sheet 18b similar to an umbrella used in the rain, and can be expanded and expanded into an umbrella shape.
A retractable rod 18 hanging from the center
The lower end of c is screwed through a joint portion 18d to the tip of a column 20 that expands and contracts in multiple stages, making it removable.

The pillars 20 are fixed at their lower ends in a reinforced concrete hangar 22 buried approximately in the center of the stadium surrounded by the side walls 10, and the roof member 18 is in a contracted state together with the pillars 20. ,
If it is stored in the hangar 22 and the opening/closing lid 24 is closed, it will not interfere with athletic events (see Figure 3a).

On the other hand, in case of rain or rain during a competition, first open the opening/closing lid 24, extend the pillars 20, raise the roof member 18 to a height that will not interfere with the eaves 16 even if it is expanded, and then gradually (See Figure 3 b, c).

When the roof member 18 is expanded to its maximum extent, it is lowered slightly and its outer peripheral edge is locked and fixed to the inner peripheral edge of the eaves 16 (see FIG. 3d).

As the locking and fixing means, for example, an electric magnet is provided on the eaves 16, and when energized, the frame 18a of the roof member 18 is attracted and fixed, and when the energization is stopped, the roof member 18 can be separated. do.

After the locking and fixing is completed, the pillar 20 and the roof member 18
After releasing the screw connection and separating the roof member 18, the column 20 is contracted, stored in the hangar 22, and the opening/closing lid 24 is closed (see FIGS. 3e and 3f).

On the other hand, the operation for removing the roof member 18 may be performed by performing the above-described operation procedure in reverse.

Further, when repairing the roof member 18, etc., the operation procedure is as shown in FIGS. 4a and 4b.

First, after opening the lid 24, extend the support 20 and raise the roof member 18 to an appropriate height.
This is expanded, and the support columns 20 are contracted to position the expanded roof member 18 on the ground.

Repairs can be easily carried out in this way without having to work at heights.

In the case of the dome-shaped roof structure having the above-described configuration, by locking and fixing the roof member 18 to the eaves 16 in the expanded state, the competition can be interrupted or canceled even in the event of rain or rain during the competition. You can continue without any trouble.

In addition, the roof member 18 can be retracted and stored during the intermediate seasons other than summer or winter, or during sunny days.
Enable competition in a natural environment.

Furthermore, in the summer when sunlight is strong, the roof member 18 can be locked and fixed to the eaves 16 to block sunlight.

Furthermore, since the roof member 18 can be contracted and stored underground, there is no waste in terms of plane and does not interfere with the competition, and the roof member 18 can be repaired at a height relatively close to the ground.

In addition, although the case where the outer peripheral edge of the roof member 18 is locked and fixed to the inner peripheral edge of the eaves 16 was illustrated in the said Example, the Example of this invention is not limited to this, and the eaves 16
It is also possible to eliminate this and lock it directly to the side wall portion 10.

Furthermore, the expansion and contraction of the roof member 18 and the expansion and contraction of the support columns 20 are performed using hydraulic pressure, electric motors, compressed air, etc., and remote control is also possible by placing sensors such as limit switches at appropriate locations. .

<<Effects of the Invention>> As explained above in the embodiments, the dome-shaped roof structure according to the present invention has a roof member that expands and contracts like an umbrella attached to a side wall or an eave provided at the upper end of the side wall. The removable locking allows for athletic events even in rainy weather, while allowing this to occur in natural conditions in sunny weather.

Furthermore, since the roof members can be condensed and stored underground, there will be no interference with the competition.

Furthermore, unlike air membrane structures, there are no problems with entrance/exit structures, lighting, ventilation, etc.
