In the seat fixing method for the air dome of the present invention, the hooking portion 12 having the rope 11 as the core, which is provided at the edge portion of the sheet of the single film or the double film, is fitted into the ridge 21 of the channel 2. When the seat 1 is lifted up by the pressure in the dome, the latching portion 12 is pressed by the stopper 3 and the side surface 22 of the channel and the seat 1 are in close contact with each other.
It is hooked on 21 to secure the seat 1 and airtightness inside the dome. Since the stopper 3 presses the hooking portion 12 in the direction of the ridge 21, that is, toward the side surface of the channel, it does not come off even if the sheet 1 is pulled upward. The connection between the seat 1 and the channel 2 has a simple structure only by locking, and the construction is also simplified.

The specifications of the air dome of this embodiment will be described with reference to FIGS. 1 and 2. This air dome is a composite membrane sheet 1 composed of a translucent outer membrane 13 and an inner membrane 14 fixed by a sheet fixing channel 2 around the dome (indicated by a dotted frame in FIGS. 1 and 2) about 50 m in length. Width 40m x Height 11m
The size of the dome 6 is. In order to inflate the sheet 1, the inside of the dome 6 is always pressurized slightly higher than the outside air pressure. An airtight revolving door 61 is used as an entrance / exit for a person, and a large chamber 62 that can separate the inside and the outside of the dome is provided for an entrance / exit of a truck or the like by a lock type door to maintain the pressurized state in the dome 6. It allows entry and exit from the outside. The degree of pressurization may be +1 to 20% with respect to the external atmospheric pressure in consideration of the surrounding weather conditions. Due to this pressurization, it usually takes 30 minutes or more for the air to escape from each door and the air dome to collapse after releasing the pressurized state.

Regarding illumination, during the daytime, sunlight is taken in through the translucent outer membrane 13 of the sheet 1, and this natural daylight is drawn between the outer membrane 13 and the inner membrane 14 by the sheet 1 as shown in FIG. The dome operation cost is reduced by making the entire dome 6 brighter by irregular reflection. At night, indirect lighting is used by the upward lighting 63. Such lighting is easier on the eyes than direct lighting. For air conditioning,
A two-layer type air conditioner 64 that blows cool air down from the cooling duct 65 above the dome and blows up warm air from the heating duct disposed on the bottom surface of the dome is used, and between the outer membrane 13 and the inner membrane 14 of the double membrane. By filling the lightweight insulation material 15 in, the efficient and economical cooling and heating is realized.

The sheet 1 is, as shown in FIG. 3 (a),
A plurality of sheets are arranged side by side and their side edges are connected as a welded portion 19 to form a film covering the entire air dome. However, if a film covering the entire dome is formed only by welding the sheet 1, it will require unnecessary labor and time for the dome construction work. Therefore, a plurality of films having a certain size should be prepared and the sheet 1 should be prepared.
A part of the connection of the above will be connected at the dome construction site. As shown in FIG. 3 (b), this connection is made by stacking the folded-back portions 16 of the other sheet to which the folded-back portions 16 of the edges of the sheet 1 are connected together, and by inserting the metal plate from the outside of each sheet 1. Tighten the bolt with 17 still pressed.

In the above, in order to achieve the pressurized state in the dome and the efficiency of cooling and heating, it is important to connect the sheet edge portion to the ground surface 41 with airtightness and fix it. In the sheet fixing method of the present invention, as shown in FIG. 4, the airtightness of the sheet edge portion is realized by the close contact between the sheet 1 and the channel 2, and the binding and fixing of the sheet 1 to the ground surface 41 are performed. This is done by pressing the retaining portion 12 provided on the above with the stopper 3 and fitting and sandwiching the retaining portion 12 into the ridge 21 of the channel side surface 22. This sheet fixing method has an advantage of simplifying the construction because of the structural features of the connected state.

The construction procedure will be described. First, as shown in FIG. 5, in the ground surface 41 around the air dome, a continuous groove 4 is dug at a position where the seat 1 is to be fixed, and partitions 47, 47 are set up substantially parallel to each other. After discarding concrete 46 at the bottom to form a flat surface, a block 48 made of concrete is laid and the reinforcing bars 44 including hoop reinforcements, vertical reinforcements, horizontal reinforcements, etc. are assembled. In Japan, it is customary to dig a trench with an inverted trapezoidal cross-section and a wide opening, usually concrete 42 (see Fig. 4).
After pouring and solidifying, the partitions 47, 47 are removed, and the groove 4 except the concrete 42 is filled with earth and sand.

Next, as shown in FIG. 6, the channel 2 is attached to the reinforcing bar 45 so as to be sandwiched by the reinforcing bar 44, and the open end 23 of the channel 2 is leveled so that it is aligned with the ground surface 41. Pour concrete 42 between partitions 47, 47. The channel 2 is manufactured by injection molding of aluminum, and the ridge 21 is provided on the side surface 22 of the channel so as to face outward, and the size thereof is such that the latching portion 12 at the edge of the seat is accommodated. When the curved channel 2 is required, the side surface 22 of the channel 2 having the ridge 21 may be cut out and bent for use. The convex piece 24 on the side surface of the channel 2 plays a role of preventing the channel 2 from coming off by being hooked on the concrete 42.

In this way, as shown in FIG. 7, the engaging portion 12 at the edge of the sheet is inserted into the ridge 21 in the channel 2 fixed to the ground surface 41. The seat hooking portion 12 has a structure in which the rope 11 is wound along the edge of the seat and has a circular section, and since the core is the rope 11, it can be freely bent. Further, as described above, although the sheet 1 of this embodiment is a multi-layered membrane, only the outer membrane 13 at the edge of the sheet is extended to provide the hooking portion 12, and the outer membrane 13 and the edge of the inner membrane 14 are separated from each other. It is open. This is because the dew condensation that occurs between the adventitia 13 and the intima 14 travels down the outer surface of the adventitia 14 and descends downward to drain from the edge of the adventitia 14. Since the outer membrane 13 and the inner membrane 14 are thermally insulated, no condensation occurs on the inner surface of the inner membrane 14.

Finally, as shown in FIG. 4, by inserting the wooden stopper 3 into the channel 2 while maintaining the above-mentioned state, the hook portion 12 of the sheet has the ridge 21 of the channel 2.
Lock it in. When the linear channel 2 is notched and bent, the corners of the stopper 3 are notched so that the end faces of the stopper 3 inserted into the channel 2 are brought into contact with each other to ensure structural strength. To do so.

From the above state, when the sheet 1 is lifted up by the pressure in the dome, it is hooked on the ridge 21 while closely contacting the channel side surface 22 so that the hooking portion 12 is pressed by the stopper 3, The fixation of 1 and the airtightness in the dome can be realized. Since the stopper 3 presses the hook portion 12 laterally, the sheet 1 does not come out upward. Further, the channel 2 itself is also firmly hooked to the concrete 42 by the convex piece 24, so that it cannot be easily pulled out.

The air dome 6 can normally be used without any reinforcement on the seat 1, but in the case of a particularly large air dome or as a measure against strong winds, as shown in FIG. A wire 67 may be suspended on the upper surface. As described above, according to the seat fixing method of the present invention, the construction is simple and the load is continuously distributed over the entire edge portion of the seat, so that there is no problem such as deterioration of the seat due to concentration of stress which is seen in bolt tightening.

As in the conventional case, the surface sandwiched between the channel and the stopper is fixed rather than fixed by bolting. Therefore, the stress caused by pressurizing the inside of the dome is uniformly dispersed over the entire edge portion of the sheet. Therefore, the sheet is not locally deteriorated. for that reason,
The durability of the seat is increased and it becomes possible to provide an economical air dome.
