Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building having various types of roofs such as a dome, a shell and an arch, which is useful for forming a large space.

[0002]

2. Description of the Related Art As a building having various types of roof covering a large space, there is known one disclosed in Japanese Patent Publication No. 4943010, that is, one having an arch type roof. This divides the structure for roof construction into two in the arch direction, and the two structure parts are fixed at the upper end (that is, the inner end in the inside and outside direction of the building in plan view) connected to each other. The upper ends of the plurality of structure parts are relatively swingably connected to each other so that the height of the roof top part is changed by undulating and swinging with respect to the parts, and the lower ends of the structure parts (that is, the building in plan view). The outer end (inward and outward direction) is vertically swingable with respect to the fixed part and is supported by the fixed part so as to be relatively movable inward and outward.
To be more specific, after assembling the two structure parts in a state of lying on the ground and connecting the upper ends to each other so that the upper ends can swing, the lower ends of one structure part are fixed and the other structure part is By pulling the lower end toward the lower end of one of the structure parts with a winch through a chain and raising the connecting part at the upper end of the structure part to a predetermined height, and fixing the lower end to the fixed part in that state. By this, an arch-shaped roof having a predetermined height is constructed.

[0003]

However, according to the above-mentioned conventional technique, since the structure portion can be assembled and connected with the structure portion lying down as described above,
Even if the roof is high and has a large span, most of the construction of the structure for roof construction can be done on the ground, and the workability and safety are good, but the chain and winch It was installed only considering the raising of the structure after the body was assembled, and since it is a temporary facility that will be removed after the structure is raised, it was not possible to easily change the roof height after construction. . In other words, there was no idea to change the height of the roof appropriately. Therefore, in the building according to the conventional technology, the internal space, that is, the internal air volume is constant, and as a result, there is no problem when the building is used for a single purpose, but sports such as baseball, soccer, and rugby can be performed. When it is used as an arena for performing, used as a concert hall, or used as an event venue for exhibitions, conferences, etc., in order to increase the utilization rate of the building, it can be used for multiple purposes. , There was an inconvenience. For example, in a building where you can play baseball,
It requires a very high roof height of at least 60m, but in buildings for other sports such as soccer and rugby, concerts and events, such a roof height is not necessary and baseball When a building with a roof height that can be used is used for other purposes, the internal air volume and ceiling height become excessive. Therefore, in a conventional building,
If you make it available for baseball and other uses,
Air-conditioning and lighting when used for purposes other than baseball becomes air-conditioning for excessive internal air volume and lighting from a ceiling that is too high, which unnecessarily increases running costs. In particular, when it is used for a concert, the reverberation time becomes long and it cannot be suitably used. The purpose of the present invention is to
It is a point to provide a roof height variable building that can be easily changed to a roof height according to various uses and can be suitably used for various uses.

[0004]

A feature of a building according to the first aspect of the present invention is that a plurality of structures capable of fixing a structure for roof construction to a fixed portion at outer ends of the roof in a plan view. The structure is divided into body parts, and the height of the roof top changes due to the structure parts wobbling and oscillating with respect to the fixed part in a state where the structure parts are connected to each other at their inner ends. The inner ends of the body parts are connected to each other so that they can swing relative to each other, and the outer ends of each structure part can swing up and down with respect to the fixed part, and are supported by the fixed part so as to be relatively movable in and out of the building. Outside the building, there are provided a slide drive device for changing and fixing the outer ends of the structural parts in the inward and outward directions of the building, and a winch device for vertically swinging and suspendably supporting each structural part. In point.

A feature of the building according to the second aspect of the present invention is that the structure for roof construction is divided into a plurality of structural parts that can be fixed to a fixed portion at the outer ends in the inside and outside directions of the building in plan view, In order to change the height of the roof top by undulating and swinging the structure parts with respect to the fixed part in a state where the structure parts are connected at the inner ends, the inner ends of the plurality of structure parts are Is relatively swingably connected, the outer end of each structure part is vertically swingably supported by the fixed part with respect to the fixed part, and the structure part is configured to be expandable and contractible, outside the building, A winch device for suspending and supporting the structure portion vertically and swingably is provided.

[0006]

According to the first aspect of the present invention, a plurality of structure portions are connected to each other at their inner ends so that they can swing relative to each other, and their outer ends are supported by a fixed portion so that they can swing vertically and move inward and outward. Since the structure for the roof configuration is configured, by moving the outer end of the structure part inward and outward, the structure parts are relatively rocked while the structure parts are undulatingly rocked,
The roof height can be freely changed within a range from zero height to a predetermined maximum height. Since the drive means for oscillating and swinging the structure portion such as the slide drive device and the winch device to change the roof height is arranged outside the building, the slide drive device and the slide drive device can be used without disturbing the use inside the building. A winch device can be permanently installed. Since a slide drive device that directly acts on the moving outer end is provided as a drive means for undulating and swinging the structure portion, the outer end is restrained by the slide drive device to stabilize the movement of the outer end, It is possible to stabilize the ups and downs of the body part. Since a winch device for suspending and supporting the structure part is also provided as a drive means for oscillating the structure part, the undulation range of the structure part can be increased and can be set freely. That is, for example, when only the slide driving device is provided as the driving means, the structure portion cannot be oscillated over the upper and lower sides of the plane connecting the vertical swing fulcrums at the outer ends, but in the present invention, You can do that. Of course, since two types of driving means having different forms are provided, the reliability can be improved.

According to the second aspect of the present invention, a plurality of structure portions are connected to each other so that they can swing relative to each other at their inner ends, and their outer ends can swing up and down to be supported by a fixed portion. Since it is configured to be expandable and contractible to form a structure for roof construction,
By swinging up and down while extending and contracting the outer edge of the structure part as a fulcrum, the structure part collapses most and contracts to the minimum, and the connecting part of multiple structure parts is the floor surface. Zero height located at the bottom of the level above or near it, and the structure part stands up most,
The roof height can be freely changed within a range between the maximum extension and a predetermined maximum height at which the connecting portion is located at the maximum level. Since the winch device for undulating and swinging the structure portion to change the roof height is arranged outside the building, the winch device can be permanently installed without hindering the use inside the building. Since the winch device for suspending and supporting the structure portion is provided as the driving means for oscillating and oscillating the structure portion, the undulating and swinging range of the structure portion can be widened and can be freely set as in the first invention. Can be set.

[0008]

As described above, according to the present invention, the roof height can be changed at any time, and while it can be applied to a use requiring a large space such as baseball, it is suitable for other uses. In addition, it has become possible to provide a roof height variable building that can be effectively used for multiple purposes by displaying the internal air volume and the ceiling height and performing appropriate and economical air conditioning and lighting. Of course, when the structure portion is constructed, the structure portion can be assembled and connected by ground work with good workability by performing the structure portion in a lying state.

As shown in (b), by changing the roof height, the shape of a triangle having two adjacent structure portions 3A in the circumferential direction as two sides, that is, the shape of the wall surface forming material 4 required changes, The wall surface forming material 4 is required to have a function of forming a wall surface while allowing its shape change. The wall surface forming material 4 having the above structure is expanded in the thickness direction by adjusting the amount of air filled inside. It is configured to change the amount to adjust the width. That is, as shown in (a) of FIG. 6, when the roof height is high and the base of the triangle is short, the width is increased by increasing the air filling amount to increase the thickness. If the roof height is low and the base of the triangle is long, as shown in (b) of FIG. 6, reduce the air filling amount and increase the thickness. By reducing the height, the width is made large corresponding to the interval between the structure portions 3A. The above building can be constructed by the following method.
