Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a membrane structure suitable for use in various events and ceremonies.

[0002]

[Prior Art]

 Conventionally, the membrane structure has generally been designed so that the air pressure in the entire room is higher than the outside air pressure, and the air pressure in the room supports the entire membrane roof, which requires air tightness. There is.

[0003]

[Problems to be solved by the device]

 Therefore, in the conventional membrane structure, it is not possible to open the room to the atmosphere by providing a ventilation window or a daylighting window, and the room tends to become a closed space. In addition, double doors and revolving doors must be installed at the entrance to maintain airtightness, which makes it inconvenient for an unspecified number of people to enter and exit at various events and ceremonies. There are some problems with danger. In addition, the structure of the membrane and the foundation tends to be large in terms of airtightness and buoyancy, which is disadvantageous in terms of construction, dismantling, and transportation, making it unsuitable for short-term events. Hard to be adopted. The present invention has been devised in view of the above circumstances, and an object of the present invention is to open the atmosphere to form an open space and to simplify the structure of the entrance and exit. The purpose is to provide a membrane structure that can be easily disassembled and transported.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a plurality of air tubes, which are arranged at intervals around the room to be defined and form a frame on the side surface and the upper surface of the room to be defined, and between the air tubes. And a film body that cooperates with the air tube to define the interior of the room. Further, the present invention is characterized in that the lower end of each of the air tubes is connected to a weight accommodating container, and a weight is loaded in the container.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of a membrane structure according to an embodiment, FIG. 2 is a plan view, FIG. 3 is a sectional side view, and FIG. 4 is a sectional plan view. 1 is a membrane structure, and the membrane structure 1 has a dome shape. The membrane structure 1 is composed of a large number of skeletonized air tubes 3 and a membrane body 5 stretched between the air tubes 3, and inside the membrane structure 1 is a semicircular indoor space 7. And the ornament 9 is attached to the upper portion of the membrane structure 1. As shown in FIG. 2, the air tubes 3 are arranged at intervals around the indoor space 7 to be defined, and the arcuate tubes 301 that form the skeletons of the side surface and the upper surface of the indoor space 7 to be defined, and each circle. The circular tube 301 is composed of an annular tube 303 that forms a frame at the center of the upper surface of the indoor space 7 to be connected by connecting the upper ends of the arc-shaped tubes 301. The circular tube 301 and the annular tube 303 make up the rigidity of the frame of the membrane structure 1. Is secured.

FIG. 5 is a side view of the lower end of the arc-shaped tube, FIG. 6 is a plan view of the weight-accommodating container, FIG. 7 is a cross-sectional view of the lower end of the arc-shaped tube and a part of the weight-accommodating container, and FIG. The side view for demonstrating supply and discharge of air is shown. The weight storage container 11 is arranged at the lower end of each arcuate tube 301, and the lower end of each arcuate tube 301 is locked to the weight storage container 11. The weight accommodating container 11 is formed in an open basket-like shape upward, and a weight 13 is loaded in the weight accommodating container 11 so that the membrane structure 1 does not move. In this embodiment, as shown in FIG. 7, the anchor bolts 15 are further embedded in the ground from the lower portion of the weight accommodating container 11 to further stabilize the installation of the membrane structure.

As shown in FIG. 8, an air supply / discharge port 21 is provided on the lower surface of the lower end of each arcuate tube 301, and an air supply tube 23 is connected to the air supply / discharge port 21. The tube 23 projects into the weight storage container 11, extends outward from the side portion of the weight storage container 11, and is connected to a blower 25 installed outside the membrane structure 1. The supply and discharge of air to and from the annular tube 303 may be performed by connecting the annular tube 303 to one of the arc-shaped tubes 301 and through this arc-shaped tube 301, or for the exclusive supply and exhaust of the annular tube 303. A tube may be provided and this tube may be used.

Since the present embodiment is configured as described above and the shape of the membrane structure 1 is maintained by the air tubes 301 and 303, it is airtight like a conventional membrane structure that utilizes the air pressure difference between indoor and outdoor. Therefore, it is possible to provide a ventilation window or a daylighting window at a desired position and form an open space. In addition, since airtightness is not required as in the past, the entrance / exit can be configured with a simple opening, and the structure of the entrance / exit can be simplified, which is convenient when an unspecified number of people enter and exit. Further, the connection between the membrane body 5 and the ground side can be simplified as in the embodiment, and the membrane structure 1 can be easily constructed and disassembled by supplying / discharging air to / from the air tubes 301 and 303. It is advantageous in terms of construction, demolition, and transportation, making it suitable for short-term events. Further, a tube 23 for supplying air to each of the air tubes 301 and 303 is projected into the weight accommodating container 11 and extends outward from a side portion of the weight accommodating container 11 so that the outside of the membrane structure 1 is exposed. Since it is connected to the blower 25 by means of, it is advantageous in enhancing the appearance of the structure for supplying air to the air tubes 301, 303.

Although the dome-shaped membrane structure 1 has been described in the embodiment, the shape of the membrane structure 1 is not limited to the dome shape and may be any shape. In addition, in the embodiment, the case where the air tube 3 is configured by the arcuate tube 301 that forms the frame of the side surface and the upper surface of the indoor space 7 and the annular tube 303 that forms the frame of the upper surface center of the indoor space 7 has been described. However, the configuration of the air tube 3 is not limited to the embodiment, for example, by omitting the annular tube 303 or using an air tube having another shape.

[Effect of the device]

 As described above, according to the membrane structure of the present invention, since the frameworks of the side surface and the upper surface of the indoor space are constituted by a large number of air tubes, airtightness is not required unlike the conventional membrane structure. Ventilation windows and daylighting windows can be provided at desired locations, and the entrance / exit structure and the connection between the membrane and the ground side can be simplified, which is advantageous in terms of construction, dismantling, and transportation. Is advantageous in improving the appearance of the structure for supplying air to the air tube.
