FIG. 1 is a perspective view showing a roof device 2 of an outdoor temporary viewing facility 1, FIG. 2 is a side view, and FIG. 3 is a plan view. As can be seen from these figures, the roof device 2 is, for example, three square pillars 3 adjacent to the rear of the outdoor temporary viewing facility 1.
And the base end of the roof frame 4 is pivotally pivoted up and down at the required height position of the square pillars 3, and the roof frame 4 is connected to the upper end of each square pillar 3 and the roof frame. The wire 6 mounted on the sheaves S1 and S2 provided at the required end of the free end 4 and connected to the winch 5 supports the roof frame 4 so that the elevation angle of the roof frame 4 can be adjusted. Is stretched over.

As shown in FIGS. 4 and 5, each of the rectangular columns 3 is formed by connecting four column members 8 each made of a steel pipe with four horizontal members 9 made of steel pipe at regular intervals in the longitudinal direction. The frame is formed in a square tower shape. In order to frame the support members 8 and the horizontal members 9, as shown in FIG.
Are fixed, and each flange 10 has 90 engagement holes 10a.
The connecting members 11 are fixed to both ends of each horizontal member 9, and each connecting member 11 is provided with a horizontal opening 11 b for fitting the flange 10 and an engaging hole 11 a. The connecting member 11 of the horizontal member 9 is fitted over the flange 10 of the column member 8 and the wedge 12 is inserted over the engagement holes 10a and 11a of the both members, so that the column member 8 and the horizontal member 9 are perpendicular to each other. The towers can be easily and easily formed by the connecting method.

As shown in FIG. 2, each of the square pillars 3 formed in a tower shape as described above is used as an outdoor temporary viewing facility 1 as shown in FIG.
Is connected via a connecting rod 14 to the main body rear support 13.
As shown in FIG. 5A, one end of the connecting rod 14 is fixed to the front horizontal member 9 of each of the square columns 3 in advance, and the connecting fitting 11 is fixed to the other end. The connection fitting 11, the flange 10 fixed to the main body rear column 13, and wedges (not shown) inserted into the engagement holes of the both are connected to the main body rear column 13. Although not shown, the three rectangular columns 3 are connected to each other by an appropriate connecting member.

The roof frame 4 is integrally framed by three vertical frames 15 corresponding to the rectangular pillars 3 and a plurality of horizontal frames 16 connecting these vertical frames 15 as shown in the plan view of FIG. A breath 17 is interposed between the horizontal frames 16. Each of the vertical members 15 includes upper and lower frame members 15a and 15b made of steel pipe and both frame members 1 as shown in FIGS.
And a plurality of connecting plates 15c for connecting the upper frame member 15a and the upper frame member 15a to the base end side of the upper frame member 15a.
A triangular reinforcing frame 22 (see FIG. 4) composed of 15f is formed. As shown in FIG. 6, each cross member 16 includes upper and lower frame members 16a and 16b made of steel pipe, and a plurality of connecting plates 16c that connect the two frame members 16a and 16b.

When the base end of the roof frame 4 is pivotally connected to the square column 3, FIGS.
As shown in (C), the base end side connection plate 15c of each vertical frame 15
And a cylindrical member 19 is fixed to the tip of the mounting plate 18 by penetrating the cylindrical member 19 so as to be orthogonal to the mounting plate 18. 9, the base end of the roof frame 4 is pivotally attached to a required height position of the three rectangular pillars 3 so as to swing up and down.

As shown schematically in FIG. 2, a sheave S2 is attached to each vertical frame 15 of the roof frame 4 at a position closer to the free end of the upper frame member 15a. A wire 6 is mounted on these sheaves S1 and S2, and one end of the wire 6 is fixed to a column member 8 of the square column 3 near the sheave S1, The other end is interlockingly connected to a winch 5 installed at the lower end of the rectangular column 3. Therefore,
By operating the winch 5 to expand and contract the wire 6, it is possible to adjust the elevation angle of the roof frame 4 pivotally attached to the square support 3. The winch 5 is preferably an electric type, but may be a manual type.

The elevation angle of the roof frame 4 is not frequently changed and adjusted, but may be adjusted and set to a desired angle when the outdoor temporary viewing facility 1 is temporarily installed. Is designed so that the base end of each vertical frame 15 is fixed to the square column 3 so that the roof frame 4 does not swing up and down. That is, as shown in FIG. 4, the front end of the frame member 15 d of the reinforcing frame 22 provided at the base end of each vertical frame 15 has a rectangular support after the winch 5 adjusts the elevation angle of the roof frame 4. 3 horizontal member 9 with pipe clamp 20
Is connected and fixed.

The roof sheet 7 is made of a synthetic resin sheet, and is entirely stretched on the lower surface side of the roof frame 4. In order to extend the roof sheet 7 to the roof frame 4, the roof frame 4 is tilted to a position shown by the imaginary line in FIG. 4

If a thick and durable sheet material made of, for example, a nylon sheet is used as the roof sheet 7, the roof frame 4 is blown up by the wind pressure in a strong wind, and its pivotal parts and the like are damaged. In order to avoid the occurrence of such a situation, a sheet material that can break the roof sheet 7 when the wind pressure applied to the roof sheet 7 exceeds a certain level is considered. Good to use.

As shown in FIGS. 1 and 2, the front end of the roof frame 4 is supported by a support member 21 erected on the front side of the outdoor temporary viewing facility 1. The supporting members 21 are provided on both left and right sides of the front end of the outdoor temporary viewing facility 1, and the upper end thereof is connected to the front end of the lower frame member 15b of the vertical frame 15 as shown in FIG. And
The lower end is connected to the main body front support 23 of the outdoor temporary viewing facility 1 as shown in FIG. Such a supporting member 21
In the case where the wire 6 is completely broken, the roof frame 4 can be prevented from dropping.

In FIG. 2, reference numeral 24 denotes an outdoor temporary viewing facility 1
Numeral 25 designates a weight for preventing the blow-up by the wind, which is installed on the front side, and a weight 25 for retaining a rope 26 for pulling each square support 3 backward in order to balance the weight with the roof frame 4.

As described above, the roof device 2 of the outdoor temporary viewing facility 1 includes a plurality of columns 3 and a roof frame 4.
And a simple structure including the roof sheet 7 extending over the wire, the wire 6 and the winch 5, so that the manufacturing is simple and the cost is not increased. A plurality of square columns 3 are erected on the rear side of the equipment 1 and each square column 3 is attached to the rear column 1 of the main body.
3 via a connecting rod 14, and the base end of the roof frame 4 is pivotally mounted at a required height of the square pillars 3, and the roof frame 4 is connected to the upper end of each square pillar 3 and the roof frame. 4, the elevation angle of the roof frame 4 can be adjusted by a wire 6 that is mounted on sheaves S <b> 1 and S <b> 2 and connected to the winch 5, and the roof sheet 7 can be stretched over the roof frame 4. Assembly can be performed easily and easily. Further, the disassembly of the roof device 2 can be performed easily and easily.

The elevation angle of the roof frame 4 is
Can be easily changed and adjusted by the expansion and contraction operation of the wire 6. For example, as shown by the solid line in FIG. 2, the roof frame 4 of the temporary viewing facility installed near the 18th hole of the golf course can make the golf ball fly high in the air clearly visible from the seats. It is preferable to set the angle of elevation such that the front side rises forward from the horizontal posture. The roof frame 4 of the outdoor temporary stage used for an outdoor concert or the like may be in a horizontal posture.

As shown schematically in FIGS. 1 and 2, the outdoor temporary viewing facility 1 includes a step frame, a support member, a horizontal member,
It is composed of a main body 1a framed in a stepped manner by diagonal material or the like, and handrails 1b installed at both left and right ends and a rear end of the main body 1a.
