Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable roof unit constituting a retractable roof (abutment portion between movable roof units, a fixed roof unit and an overlapping portion between movable roof units or movable roof units, movable roof unit). And a roof top structure or a slide part between the leg structure) and a waterproof material, and is mainly applied to a retractable roof of a large building such as a dome structure.

[0002]

2. Description of the Related Art Recently, even in dome-shaped structures, when the weather is good, natural light and outside air are taken in as much as possible.
Various types of retractable roofs have been developed in order to give a feeling of openness.

As for the opening and closing method, the roof is divided into a plurality of roof units and moved along an arcuate track (mainly in the case of a circular dome, etc.) or a parallel track, or a track is provided along the roof surface and overlapped. There are various methods such as.

For example, Nikkei Architecture August 21, 1989 issue (Nikkei BP) pages 108-119,
A sky composed of four roof units, two movable roof units that can move in parallel along a parallel track, and a fixed roof unit on one side and a rotary movable roof unit that can rotate in another direction on the other side. There is a retractable dome roof called the dome.

By the way, in the case of a retractable roof, the periphery of the movable roof unit such as a butting portion between the movable roof units, an overlapping portion between the fixed roof unit and the movable roof unit or between the movable roof units, and a sliding portion above and below the movable roof unit. There is a problem of raining in the section, and in large buildings such as dome structures, rubber waterproofing materials such as chloroprene rubber are used for the abutting part and the overlapping part, or an air tube is installed along the abutting part. And the method of sending air into the air tube.

[0006]

In the case of a rubber waterproof material, the most problematic is the problem of restorability. In order to secure the waterproof property when the roof is closed, it is necessary to apply a pressing force to the abutting part against the waterproof material, but even if the pressing force is removed when the roof is opened, it will not completely return to the original state. However, there is a problem with the water stoppage when closing again.

In particular, in cold regions and the like, in many cases, the rubber is left closed for a long period of time in winter, so that the resilience of rubber and the pressing force become serious problems.

Further, when the building becomes large, the deformation due to wind pressure, the deformation due to the movement of the movable roof unit and the vibration such as an earthquake, the deformation due to the pressing force applied to the abutting portion, etc. also become large. Design becomes difficult.

In the case of using the air tube, in order to ensure the waterproofness, it is necessary to constantly send air by using a fan or the like, which causes problems of running cost and maintenance.

The sliding portion cannot slide the movable roof unit with a structure in which a rubber waterproof material is closely attached, and it is customary to have a structure different from the abutting portion and the overlapping portion.

Further, the butt portion and the overlapped portion also usually have different performances required for water blocking performance, and various types of water blocking materials of different shapes or materials are used for each part around the movable roof unit. In addition to having to prepare a water blocking material, there is a problem that the site work becomes complicated.

The present invention relates to a retractable roof, which has a relatively simple structure, is less likely to deteriorate in terms of waterproofing, and has one type of waterproofing material such as a butt section, an overlapping section, and a sliding section.
It is an object of the present invention to provide an economical waterproof structure applicable to various parts and a waterproof material used therefor.

[0013]

The water blocking structure for a retractable roof in the first invention of the present application is for a butt portion where the ends of the movable roof unit are butted against each other, and the butt portion is provided on each of the facing surfaces. A water blocking material having fins is attached along the fins, and the fins are arranged so as to overlap each other in a plane.

Regarding the abutting portion, there are cases where the movable roof units that move in parallel are abutted, and cases where the movable roof units that turn are abutted.

The waterproof material is continuous along the abutting portion,
The fin pieces alternately project from the facing surfaces of the left and right movable roof units.

Further, in order to effectively prevent the invasion of rainwater and the like into the inside, the fin pieces protruding from the left and right movable roof units form a recess toward the outside air side (usually above). It is preferable to do so, and in this case, this recess can also be used as a gutter.

The recess is formed not only by bending or bending the fin piece itself, but also by projecting the fin piece upward at a predetermined angle with respect to the mounting base portion of the water blocking material so that the fin piece is provided between the fin piece and the mounting base portion. It may be formed with a recess or the like.

A gap may be left between the fin piece of the waterproofing material and the facing surface which overlap with each other in plan view, but the tip of the fin piece is provided on the facing surface for more reliable water tightness. It can be considered that the auxiliary water stop material is brought into contact with and brought into close contact.

For such an auxiliary water blocking material, for example, a fitting portion is formed in the water blocking material, and the auxiliary water blocking material is fitted into the fitting portion to combine the water blocking material and the auxiliary water blocking material. It can also be used in a closed state.

It is desirable that the waterproofing material has excellent weather resistance, for example, a material made of an elastic material made of synthetic rubber such as chloroprene rubber is suitable, but synthetic resin, metal mold material and the like can also be used. .

In the waterproof structure of the openable roof according to the second invention of the present application, the roof is vertically overlapped when the roof is opened, and when the roof is closed, the lower wall of the upper roof unit end and the lower wall of the lower roof unit end rise. This is for overlapping overlapping parts, and a water blocking material having fins is attached to each of the facing surfaces along each overlapping part, and the fins are arranged so as to overlap each other in a plane.

Regarding the overlapping portion, there are cases where the ends of the movable roof units that move in parallel are butted against each other, and there are cases where the ends of the movable roof unit that turns is butted.

The water blocking material is continuous along the overlapping portion, and the fin pieces alternately project from the facing surface.

The intrusion of rainwater into the overlapping portion in this case is mainly due to wind pressure from the bottom to the top or the side of the outside air, and the outside air side (usually downward or side).
It is preferable to form the concave portion toward.

Further, as in the case of the abutting portion, it is conceivable to attach an auxiliary water blocking material to bring the tip of the fin piece into contact.

In the waterproof structure for a retractable roof according to the third invention of the present application, the upper or lower end of the movable roof unit slides in parallel or while turning with respect to the roof top structure or leg structure when the roof is opened or closed. The water blocking member having fins is attached to each of the facing surfaces along the slides, and the fins are arranged so as to overlap each other in a plane.

The movable roof unit is of a type in which the upper end is swiveled around the roof top structure (the lower end is swung along the leg structure) and the upper end is translated along the roof top structure (the lower end is the leg). Parallel roof structure), an arched movable roof unit without a roof top structure translates or swivels along the rails on the structure side wall as a leg structure or on the structure foundation. Etc.

The intrusion of rainwater into the slide portion in this case is mainly due to the wind pressure from the bottom to the top or the side, which is the outside air side, and the recess is formed toward the outside air side (usually downward or sideward). Preferably.

Regarding the slide portion, a gap is formed between the fin piece of the waterproofing material and the facing surface, so that the movable roof unit can be smoothly opened and closed, and rainwater is mainly intruded by the fin pieces that overlap in a plan view. To prevent.

The water blocking material according to the fourth invention of the present application is for use in the water blocking structure of the present application described above, and has a strip plate-shaped mounting base and one protruding side surface of the mounting base.
Alternatively, a plurality of fin pieces are integrally molded with a synthetic polymer material such as synthetic rubber or synthetic resin or a metal material.

Further, a fitting portion for mounting an auxiliary water blocking material is formed on the surface of one side of the fin of the mounting base of the water blocking material, and the auxiliary water blocking material is mounted on this fitting portion if necessary. The tips of the fins of the water blocking material facing each other can be closely attached.

That is, when one type of waterproofing material is commonly used for the abutting portion, the overlapping portion, the sliding portion, etc., the auxiliary waterproofing material is attached only to the necessary portions, and the auxiliary waterproofing material is not required. For, it is possible to attach only the waterproof material.

It is desirable that the auxiliary water blocking material is a synthetic polymer material such as synthetic rubber or synthetic resin, or a foamed material thereof, which can obtain a large deformability. In addition, the shape is preferably a hollow tubular shape, a cylindrical shape, or the like, which is hollow and easily deformed elastically. In that case, it is desirable to provide a partition wall in the hollow portion so that the local deformation does not become too large. .

As for the water blocking material, if a synthetic polymer material such as synthetic rubber or synthetic resin is used, the water blocking material and the auxiliary water blocking material can be integrally molded.

The waterproof structure of the present application is mainly intended for openable roofs of large buildings such as dome structures, but is not limited to these and is applied to openable roofs of various shapes and scales. be able to.
