Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a dome-shaped roof structure, and 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 used for athletic events such as baseball stadiums and track and field stadiums do not have roofs attached to them.

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.

In addition, not only will it be difficult to provide lighting and ventilation inside the venue, but the purpose of competing or watching competitions in a natural environment will be lost.

(Purpose of the Invention) This invention was made in view of the above-mentioned conventional problems.The roof can be attached or detached depending on the weather, allowing natural lighting and ventilation during sunny days, allowing exercise in a natural environment. 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 consisting of a side wall part erected on the ground and a dome-shaped roof part whose periphery is fixed to the side wall part, wherein the roof part is It 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 separated from the support in the expanded state to form the side wall section. It is characterized by being removably locked to.

(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 that is composed of a cylindrical side wall section 10 that stands on the ground and has an open upper end, and a dome-shaped roof section 12 that covers the upper end opening. A stand 14 for accommodating spectators is provided inside the side wall portion 10.

The roof part 12 is formed into a ring shape by combining reinforcing bars in a truss shape, and the outer peripheral edge is fixed to the upper end of the side wall part 10.
It consists of an eaves 16 that extends inward, and a roof member 18 that expands like an umbrella over the inner circumferential edge of the eaves 16 that is open at the center and removably locks the outer circumferential edge.

The roof member 18 is a frame 18 similar to an umbrella used in rainy weather.
The lower end of the rod 18C, which is configured to expand and contract in an umbrella shape and hangs down from the center, is screwed to the tip of the strut 20 that expands and contracts in a multi-stage manner through a joint portion 18d. It is possible to escape.

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 this hangar 22 and the opening/closing lid 24 is closed, it will not interfere with athletic events (see FIG. 3(a)).

On the other hand, in case of rain or rain during a competition, first open the opening/closing lid 24, extend the support column 20, and then open the roof member 1.
8 expands without interfering with the eaves 16. When it rises to a height of 1, it gradually expands (see Figures 3 (b) and (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. 3(d)).

As the locking and fixing means, for example, an electric magnet can be used
6, and by energizing the bone 11 of the roof part 018.
The roof member 18 can be separated by adsorbing and fixing the roof member 18a and stopping the electricity supply.

When the locking and fixing is completed, the threaded connection between the pillar 20 and the roof member 18 is released, the roof member 18 is separated, and then the pillar 20 is contracted, stored in the hangar 22, and the opening/closing lid 24 is closed ( (See Figures 3(e) and (f)).

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

In addition, when repairing the roof member 18, etc., please refer to Fig. 4 (a).
), (b).

First, after opening the lid 24, extend the support 20, raise the roof member 18 to an appropriate height, and expand it.
The roof member 18 expanded by contracting the pillars 20 is positioned on the ground.

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

In 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 may be canceled or canceled due to rain or rain during the competition.
You can continue without stopping.

In addition, the roof member 18 can be contracted and stored during the intermediate seasons other than summer or winter, or during clear weather, so that competitions can be held 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 relatively close to the ground.

In the above embodiment, the outer peripheral edge of the roof member 18 is connected to the eaves 16.
Although the embodiment of the present invention is not limited to this example, the eaves 16 may be omitted and the eaves 16 may be directly locked to the side wall 10.

In addition, the expansion and contraction of the roof member 18 and the expansion and contraction of the pillars 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. becomes.

(Effects of the Invention) As explained above in the embodiments, the dome-shaped roof structure according to the present invention has a roof part that expands and contracts like an umbrella and is removably locked to the side wall part, so that it can be used even in rainy weather. While allowing for athletic competitions, it also allows for this in a natural environment when the weather is clear.

Additionally, since the roof can be retracted and stored underground, it will not interfere with competitions.

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