  In the case of the present invention, the first fixing member for fixing the net and the second fixing member for fixing the rope are common even if the net and the rope for suppressing the deformation of the sheet subjected to strong wind, for example, receive upward force. Because it is connected via a washer, the fixed state is more stable than in the case of the conventional structure in which the net is fixed independently by the first fixing member and the rope by the second fixing member without using a washer. It can be made. That is, even if one of the fixing members is easily removed, the other fixing member that is difficult to remove makes it difficult to remove one of the fixing members, so that the fixed state can be stabilized.

  According to the third aspect, the sandwiching member presses the end portion of the sheet mainly against the attached surface by the pressing member in which the portion covering the washer is fixed to the attached surface. Therefore, there is no need to provide a fixing hole at the sheet end.

  According to the fourth aspect, for example, even if a strong wind is applied to the seat and a force that moves to the inside of the air dome acts on the seat, the sandwiching member can be prevented from coming out of the pressing member.

  According to claim 5, the first fixing member is configured so that the embedded portion of the first to third fixing members is embedded in the mounting surface, a washer is placed thereon, and the outer peripheral edge of the net is fixed to the washer. The fixing portion is attached to the corresponding embedding portion, the fixing portion of the second fixing member is attached to the corresponding embedding portion so as to fix the end portion of the rope, and the third outer periphery of the sheet is further fixed. The air dome can be assembled by attaching the fixing portion of the fixing member to the corresponding embedded portion. On the other hand, when disassembling the air dome, the fixing portion of each fixing member is removed, and the rope, net, and seat are removed, or in addition, the washer may be removed. Therefore, the embedded portion of each fixing member remains at a predetermined position on the attached surface. At this time, as in the third aspect, as the third fixing member, a configuration is adopted in which the end portion of the sheet is sandwiched between the mounting surface by the sandwiching member and the sandwiching member is pressed from above by the pressing member. Thus, although it is necessary to align the embedded portion and the fixing portion, strict alignment between the fixing member and the sheet can be eliminated, and workability can be improved.

  The present invention will be specifically described below.

  1 is a perspective view showing an example in which the present invention is applied to an air dome for covering a pool, FIG. 2 is a sectional view showing the air dome, and FIG. 3 is a front view showing a fixing structure of the present invention.

  As shown in FIG. 3, the outer peripheral edge 5a of the seat 5 is fixed on the surface 4 to be attached by the seat fixing member 10, and is deformed into a convex shape by blowing air into the inside. The net 6 suppresses the spread of the sheet 5, is provided on the upper side of the sheet 5, and the outer peripheral edge 6 a is fixed on the attached surface 4 by the net fixing member 20. The rope 7 is for fixing the net 6. The rope 7 is provided on the upper side of the net 6 as described above, and the end 7 a is fixed on the attachment surface 4 by the rope fixing member 30. The sheet fixing member 10, the net fixing member 20, and the rope fixing member 30 are fixed to the attached surface 4 via a washer 40 disposed on the attached surface 4.

  The washer 40 is formed in a strip shape in plan view, is spaced along the lower end 3 of the air dome 1, and has a surface to be mounted in a direction crossing the lower end 3 with respect to the longitudinal direction, for example, an orthogonal direction. 4 in the recess 4a. The concave portion 4a has an opening into which the washer 40 just enters, and the depth is set to a dimension such that the flat upper surface 40a of the washer 40 is substantially flush with the upper surface of the mounted surface 4 (see FIG. 3).

  As shown in FIGS. 4 and 5, the sheet fixing member 10 includes a sandwiching member 11 provided substantially parallel to a direction A in which the lower end 3 of the air dome 1 extends, a retaining member 12 that retains the sandwiching member 11 from above, and a retaining member. And anchor bolts 13 for fixing the member 12 to the mounting surface 4.

  The sandwiching member 11 is for winding an outer peripheral edge 5a of the seat 5 on the outer side, and sandwiching the outer peripheral edge 5a between the flush mounting surface 4 or the washer 40, for example, C-shaped steel. In order to increase the area sandwiched between the mounted surface 4 and the washer 40, the opening 11a side is directed upward, and the wide surface 11b opposite to the opening 11a is opposed to the mounted surface 4 and the washer 40. The washer 40 is arranged so as to be substantially orthogonal to the longitudinal direction of the washer 40. The sandwiching member 11 is wound so that the outer peripheral edge 5 a of the sheet 5 covers at least the entire area of the wide surface 11 b and is drawn upward from the outside of the sandwiching member 11. The outer peripheral edge 5a of the sheet 5 may be wound around the sandwiching member 11 in a single, double or more manner in a state where different portions of the outer peripheral edge 5a overlap on the sandwiching member 11.
