The framed panel 1 is a regular polygonal rigid frame body having an even number of four or more corners, in this example, a regular hexagonal rigid frame body 2, and a regular frame having a peripheral edge attached to the rigid frame body 2. A flexible sheet 3 having a polygonal contour shape, and three linear constant width reinforcing tapes 4 fixed to the flexible sheet 3 along the surface of the flexible sheet 3 are provided. Yes.

  The rigid frame 2 is configured by connecting and fixing linear structural members having the same length, for example, metal pipes to form regular hexagons. The flexible sheet 3 is a sheet formed from a material such as a resin film, a nonwoven fabric, or a woven fabric. The reinforcing tape 4 is a synthetic resin tape having a high tensile strength, and has a tensile strength greater than that of the flexible sheet 3.

  The outer peripheral edges 3 a to 3 f of the flexible sheet 3 are fixed to the frame members 2 a to 2 f that define the respective sides of the rigid frame 2. As a fixing method, for example, attachment holes are formed at regular intervals along the outer peripheral edges 3 a to 3 f of the flexible sheet 3, and the frame members 2 a to 2 f of the rigid frame 2 are attached to the attachment holes at regular intervals. A hook that can be inserted is formed, and these mounting holes can be hung on the hook. The outer peripheral edges 3a to 3f of the flexible sheet 3 may be fixed to the frame members 2a to 2f of the rigid frame 2 at regular intervals using a fastening band or the like. A linear member having a constant width is disposed along each of the outer peripheral edges 3 a to 3 f of the flexible sheet 3, and the flexible member 3 is flexible between the linear member and each frame member 2 a to 2 f of the rigid frame 2. The straight member may be fixed to each frame member 2a to 2f of the rigid frame 2 using a fastening fitting in a state where the outer peripheral edges 3a to 3f of the sheet 3 are sandwiched.

  Each of the reinforcing tapes 4 has a pair of corners in a point-symmetrical position in the flexible sheet 3, that is, between the first corner 3A and the fourth corner 3D in the drawing, the second corner 3B and the second corner 3D. It is fixed to the flexible sheet 3 between the third corner 3E and the third corner 3C and the sixth corner 3F. Both end portions of each reinforcing tape 4 are fixed to the corner portions 3 </ b> A to 3 </ b> F of the rigid frame 2.

  Here, as the wire for tensile reinforcement of the flexible sheet, a reinforcing wire composed of first and second fitting members that sandwich the flexible sheet 3 and can be fitted to each other from both sides of the flexible sheet 3 is used. Thus, the reinforcing wire may be fixed to the flexible sheet.

  In addition, although the flat framed panel 1 of this example is a regular hexagon, a regular tetragon, a regular octagon, etc. may be sufficient.

(Roof structure constructed using flat framed panels)
Next, FIG. 2 is explanatory drawing which shows the roof structure of the agricultural house which used the flat panel 1 with a frame 1 sheet. The roof structure of an agricultural house uses a flat framed panel 1 as a roof panel. The flat frame-equipped panel 1 is supported by a plurality of, in this example, six columns 5a to 5f. The support columns 5a to 5f are fixed to the first to sixth corners 3A to 3F of the regular polygonal rigid frame 2, respectively. The support columns 5a to 5f have the same length, and extend from the framed panel 1 in a right angle direction. One end of a pull wire 6 is connected to the wire hooks 4a and 4b at both ends of each reinforcing tape 4 in the panel 1 with a frame. In FIG. 2, only two tension wires are shown. The other end of the tension wire 6 is fixed in a predetermined tension state to the anchor 7 embedded in the ground, and the reinforcing tape 4 is maintained in the predetermined tension state by the tension wire 6.

Moreover, in the up-down direction (vertical direction) in FIG. 4, it is connected in the state which overlap | superposed one outer peripheral edge of the panel 1 with a frame. Further, in each of the framed panels 1, one end of the tension wire 6 is coupled to both ends of the reinforcing tape 4 except for the corners coupled to the adjacent framed panel 1. The other end is fixed to the anchor 7 embedded in the ground in a predetermined tension state. When viewed from above, each of the pulling wires 6 is pulled linearly in the same direction as the connected reinforcing tape 4, and each of the reinforcing tapes 4 is maintained in a tensile state.

  Here, the triangular gap 10 and the diamond-shaped gap 11 formed between the adjacent flat framed panels 1 may be sealed using the corresponding framed panel. Moreover, by forming a wall surface using a wall surface material such as a vinyl sheet, an agricultural house having an indoor space surrounded by a roof surface and a wall surface composed of a plurality of panels 1 with frames is obtained.
