Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a building equipped with a retractable roof suitable for sports stadiums and the like.

<Prior Art> In buildings with conventional circular dome-shaped retractable roofs, the slope of the roof is gentle and snow accumulates, and retractable roofs are inferior in strength to fixed roofs. Also, if the snow that has fallen on the roof accumulates beyond a certain level,
There was a drawback that the opening/closing operation itself was impossible. For this reason, some models are equipped with snow melting devices for areas with heavy snowfall. For example, Japanese Patent Application Laid-Open No. 63-63847.

<<Problems to be solved by the invention>> In the above-mentioned conventional building with a circular dome-shaped retractable roof, the cost of heating a large space and installing a snow melting mechanism was enormous.

The purpose of the present invention is to provide a building with a retractable roof that secures the same plane area as the dome type and eliminates the need for a snow melting mechanism.

<Means for Solving the Problems> In order to achieve the above object, the building with the retractable roof of the present invention is constructed by dividing the truncated part of the pyramid-shaped building into a subdivision centered on the beam forming the ridge. It is divided vertically into sections, which can be opened and closed vertically.

《Operation》 Due to its pyramidal shape, natural snow sliding occurs. In addition, the truncated part is designed to be opened and closed, and the opened and closed parts are vertically divided at each corner around the ridge of the building, and when opened and closed, they shield the entrance and side of the building. It's not going to happen.

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

Figure 1 shows a panoramic view of a building 1 according to the present invention, which is shaped like a square pyramid and has an inclination angle of about 45 degrees. The top of the outer wall is truncated at 1/2 the height of the building 1, and steel beams 2 placed at each corner of the square pyramid are exposed above.

That is, the truncated portion 3 without an outer wall forms the open top of the building 1, and this portion is opened and closed by the retractable roof 4. Since the retractable roof 4 covers the truncated portion 3, it forms a square pyramid when the truncated portion 3 is closed. In other words, the retractable roof 4 is composed of small sections obtained by vertically dividing the top of this square pyramid, and these subsections constitute the retractable roof 4 that moves up and down along the steel beam 2. That's what I'm doing. That is, the retractable roof 4 is made by subdividing the truncated part of the square pyramid into each corner.
In other words, it is obtained by vertically dividing the triangular plane formed by the pyramidal sides from the apex to the center of the base.

A small umbrella-shaped top chamber 5 is installed at the top of the building 1 where the steel beams 2 meet in order to cover the joints where these subdivisions that make up the retractable roof 4 meet at the top of the building 1 and improve water resistance. ing.

This retractable roof 4 has rails 6 laid on the steel beams 2.
The door is opened and closed by a moving mechanism such as a guide rail 8 provided on the side wall 7 of the building. Since the building 1 is a square pyramid, the side wall 7 has a waterproof structure on its outer surface.
It can also be called a fixed roof.

The retractable roof 4 is driven by a moving mechanism as shown in FIGS. 2 and below, and bogies 9-9 are mounted above and below the rear surface of the ridge, and guide wheels 10 are mounted at the bottom ends of both wings. A joint beam 11 extending between the steel beams 2 is provided near the upper end of the side wall 7.
Building 1 is now reinforced. Guide rails 8 of the side wall 7 are provided parallel to the steel beam 2 on the left and right sides of the steel beam 2. The retractable roof 4 is a rail 6 of the steel beam 2
Move up and down. In this case, the two bottom wings are supported on the guide rail 8 by means of guide wheels 10.

As shown in Fig. 3, the rails 6 are made of channel steel, and the rails 8
is an anti-lifting wheel 1 which is constructed of H-shaped steel, hangs down from the upper truck 9 or guide wheel 10 to the back surface of its upper edge, and is attached by bending the tip of the hanging end into a hook shape.
2 has been received.

Details of the traveling bogie 9-9 mounted on the ridge of the retractable roof 4 and running on the rails 6 are shown in FIG. A running wheel 14 is pivotally supported at both ends of a bogie frame 13, and an anti-lifting wheel 12 fixed to a rail 6 is provided at the tip of a suspension plate 15 fixedly hanging downward near the center bottom. A pivot 17 is rotatably supported back and forth by an equalizer shaft 16 at the center of the upper side of the bogie frame 13.
A retractable roof 4 is provided, and is pivoted so as to be rotatable left and right by a pivot 18 that spans the front and back of the pivot base 17.
The mounting base 19 is supported.

The shape of the mounting base 19 is mountain-shaped, and the apex thereof is set at a right angle in this example to match the corner angle of the quadrangular pyramid. If it is a triangular pyramid, all you need to do is prepare a mounting base with a 60 degree apex angle. Bolt holes 20 for fixing the retractable roof 4 are bored in the mounting base 19. Each of the retractable roofs 4 is fixed integrally with the truck 9 through the bolt holes 20, and moves together in the direction of movement of the truck 9.

Now, the driving force for the movement is generated by connecting one end of a moving traction member 21 such as a metal rope to the trolley frame 13, and wrapping the other end around a direction changing sheave fixed to the top of the steel beam 2. It is obtained by winding it around a winch installed at the base of 2. Since the inclination angle of the roof of the building 1 is large, the retractable roof 4 opens under its own weight when it is opened, and the winch operates and acts only when it is closed and when the closed state is maintained.

In the configuration described above, by pulling the traction member 21, the retractable roof 4 can be opened and closed up and down, and each adjacent edge can be moved in position when closing, since the mounting base 19 of the trolley 9 can roll around the pivot 18. Some hits can be corrected slightly.

<<Effects>> As described in detail above, the building with the retractable roof of the present invention is constructed in the shape of a pyramid, and the truncated portion of the retractable roof is divided into small sections at each corner with the ridge at the center. Because of this structure, it is easy to make the slope of the roof steep, snow is removed by sliding snow, and the roof can be opened and closed at any time without using a snow melting device. Also, compared to a circular dome-shaped building, the air volume is smaller, so air conditioning costs are also reduced. Furthermore, since it is pyramid-shaped, if it is made into a polygon, the retractable roof can be finely divided into small sections, which is convenient for handling and transportation in terms of construction, and it can be opened and closed separately in small areas. Furthermore, when the retractable roof is fully opened, the retractable roof is located at a corner, so there is no risk of blocking the central part of the side of the building, and openings such as entrances and exits can be placed in the center. Mechanically, there are various effects such as the self-weight of the retractable roof does not act directly on the beams as a roof load, and the self-weight is directly dispersed to a large extent in the direction perpendicular to the foundation without going through the beams. .
