Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a building with a retractable roof suitable for an athletic stadium or the like.

(Conventional technology) Recently, all-weather stadiums have been attracting attention, and by focusing on the problems of the air membrane structure, the roof can be partially opened and closed depending on the weather, allowing natural lighting and ventilation on sunny days. In addition, in order to allow athletics to be held even in rainy weather, the present applicant is accommodated by sliding on a fixed roof, and opens and closes an opening in the inner circumference of the fixed roof while being guided by a guide member. He first proposed a retractable dome roof with a movable roof and a movable roof (Japanese Patent Laid-Open No. 61-79099, Japanese Patent Application No. 61-7909).
1-163592).

The retractable dome roof is supported by a reinforcing beam installed at the upper edge of a circular side wall erected on the ground, and an annular beam connecting the bases of several roof support beams extending from this side wall toward the center. The movable roof member opens and closes the donut-shaped fixed roof having a circular opening in the center of the roof.

The details of the roof member are that it is divided into several stages concentrically from the center of the opening in the outer radial direction and stacked, and the outer circumferential side is configured as a lower movable roof and the inner circumferential side is configured as an upper movable roof.
The opening is opened and closed by moving it on the support beam.

In other words, it is a multi-layer V4 structure in which a lower movable roof is superimposed on a fixed roof, and an upper movable roof is superimposed on top of that, and when these are superimposed on the fixed roof, an opening is formed in the center of the dome roof. . When closing this opening, move the movable roof from above the fixed roof! ? I was trying to block fl D.

(Problem to be Solved by the Invention) As described above, in a structure in which a movable roof is superimposed on a fixed roof, the movable roof is multi-staged according to the opening ratio and size of the roof, and each of them is sequentially Overlapping on the fixed roof @
It has a layered structure.

As a result, most of the open areas are limited to openings, which lacks a sense of openness, and it also feels economically expensive to apply to roofs with simple shapes.

The present invention has been made in view of the above circumstances, and its purpose is to provide a building equipped with a retractable roof that avoids complicated configurations such as telescopic beams and overlapping structures between movable roofs, and provides a greater sense of openness.

(Means for Solving the Problems) In order to achieve the above object, the movable roof of the present invention includes a pair of opposing substantially triangular side walls erected on a base, and a pair of substantially triangular side walls erected on a base. It consists of a gable-type retractable roof that covers the area from the top of the side walls to the top of the foundation in multiple stages with multiple movable roofs.

(Function) A retractable roof rises continuously from the ground, foundation, etc. to the ridgepole, and the movable roofs, such as those obtained by horizontally dividing the midway part into multiple stages, are not constrained to each other's positions. By moving freely, you can obtain the same plane space from the ground to the inside of the building, and also freely select the opening position.

(Embodiments) Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings.

FIGS. 1 and 2 show the entire building A. Approximately triangular side walls 1-18 are provided on the left and right, and entrances and exits 2 are provided on the bottom side of the building at the center and left and right sides.

Further, the retractable roof 3 is configured in a gable shape extending from the top of the side wall 1-1a to the base 4 of the building Δ.

In addition, the retractable roof 3 has large beams 6 constructed on the inner surface of each side wall 1-18 and below the rose bed 5 along the contour shape of the side wall.
It is supported by

The girder 6 includes a purlin board 7 and wire bundle 8 passed between the side walls 1-1a.
The spacing in the girder direction is maintained fixed, and the inclination angle is reinforced and maintained by the connecting beam 9. A base 4 is located between the side walls 1 and 1a.
There is an intermediate beam 10 passed from the wire bundle 8 to the wire bundle 8.

Furthermore, the girder 6 has rails 1 installed in three rows in parallel in the beam direction.
There are 1, 11a, and 11b. The retractable roof 3 has three movable roofs 12, 12a divided into three stages in the horizontal direction.
12b are assembled in multiple stages to cover one side of the slope. These movable roofs are constructed of rails 11.1 arranged one after the other from the outside to the inside.
1a and 11b, the roofs 12.12a and 12b slide in parallel from the outside to the inside.

The arrangement of each of the movable roofs 12.12a, 12b described above is partially shown in FIG. 3 from the direction of the side wall 1. As shown in the figure, rails 11.degree. 11a, 11b are laid on the girder 6 from the outside to the inside, and a movable roof 12, 128, 12b is installed on each rail so that it can be moved through an active mechanism 13. That is, the movable roofs 12.12a and 12b are constructed of steel frames,
This is covered with tension membrane or stainless steel board. Each sliding mechanism 13 is arranged above and below both ends in the girder direction.

As shown in Fig. 2, when the outer movable roof 12 and the middle movable roof 12a are moved to the lowest position, and viewed from above across the side walls 1-18, they are sequentially moved from the outside to the inside as shown in Fig. 4. It is mounted on a separate track. Each rail 11. lla,
11b is constructed by attaching a rail to the bracket 14 attached to the girder 6, and the base of the bracket 14 and the side wall 1-1a
A gutter 15 is installed at the corner of the rail rail 11.11a, 11
It is installed in parallel to b. For rain protection, the lower end of the waterproof plate 16, which is curved from the outer surface of the parabet 5 to the inner side of the outer wall 1, is
It is bent into a letter shape to form a gutter 15.

The roof 12b is constructed by extending the front surface, tip end surface, and back surface of each bracket 14 and bending it in a U-shape on the lower bracket 14 along the inside of the outer wall 1. , forming a gutter 15 and having the same structure one after another. In conjunction with the rain closing dance described in Figure 5, Tamedo Dankei 1
3 details are shown.

In addition to the side wall 1 side, the waterproof board 16 is installed on each movable roof 12° 12a.
, 12b also hangs down from the upper edge along the side surface of the end, and has a hanging end facing the gutter 15, and also serves as a drain plate 1.
6b is installed to ensure rain protection.

In addition, although the above rain cover is explained for the side wall 1, the same applies to the side wall 1a.

Next, referring to the sliding mechanism 14, the movable roof 12.
Rails 11° 11a of the framework frame 17 of 12a and 12b,
On the back side of the end near 11b, there is a sliding layer material 1 such as Teflon.
A gripping member 19 in the shape of channel steel is attached,
The tips of the vertical sides of the gripping member 19 are bent inward at right angles, and the bent pieces 20 are attached to the bracket 1 via the sliding material 18.
The movable roof 12 is fixed to the back surfaces of both wing ends on the upper sides of the rails 11.11a and 11b laid on the roof 11, and prevents the movable roof 12 from rising.

In addition, if the sliding part of the rail 11 corrodes and rust occurs, it not only causes abnormal wear of the sliding material 18 on the roof side, but also causes damage to the decoy VJ.
Since the resistance will also be large, if the roof is not frequently closed 131, it is advisable to attach a rust-resistant metal plate 21 such as a stainless steel plate or a brass plate to the sliding surface (upper side) of the rail 11.

As mentioned above, each rail 11. The movable roofs 12, 12a and 12b can be freely moved vertically by a driving force such as a winch or a hydraulic cylinder. For example, as shown in FIG.
When a is moved to overlap the middle stage where it is normally located, only the upper part of the building Δ is opened. Furthermore, as shown in FIG. 7, when the movable roof 12b with its lowermost position as its home position and the movable roof 12a with its intermediate position as its home position are moved to the upper stage, the building A can be seen from the ground.
This results in an opening that is flush with the interior.

The following is also shown in Figures 8 and 9. vJ roof 12.12a, i
The movement mode of 2b will be illustrated below. In all of these examples, the left and right sloped roof surfaces are opened and closed symmetrically, but since the rails of each movable roof are different, it is also possible to open and close them asymmetrically.

Note that the movable roof 12 may have a structure in which the same horizontal length is divided into two or three parts depending on the length to the building.

(Effects) As described in detail in the embodiments above, according to the building equipped with the retractable roof of the present invention, the retractable roof can be freely opened and closed from the building foundation to the top of the building with substantially triangular side walls. Since this retractable roof is composed of movable roofs divided into multiple stages, it is possible to form a free opening from both sides of the building to the top. Therefore, not only can the aperture position be moved and changed depending on the direction of incidence of direct sunlight, but when you can hear the bottom part, the floor surface and the ground surface are on the same plane, giving you a sense of spaciousness and an open feeling. can be changed.

In addition, it does not use complicated mechanisms such as moving 1F7J beams or telescopic beams, and has a simpler structure than dome-shaped shell structures, and there is no fixed roof surrounding the floor, giving it a greater sense of openness. .
