Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a roofing sheet used for cultivation agricultural houses, temporary roofs at construction sites, and the like.

[0002]

[Prior art and its disadvantages]

 Agricultural houses such as vinyl houses for conventional cultivation, temporary roofs at construction sites, etc. are constructed by pipes, and agricultural vinyl sheets are stretched on top of the frameworks, and the required locations are converted to frames. Generally, it is fixed. However, this method has the drawbacks that the material cost of the framework is expensive, the construction is also required to be precise and complicated, and the work of stretching the vinyl sheet is also a fixing work on the side of the lower shed and a framework. It is difficult to fix the required places with special hardware between the plastic sheet and the agricultural vinyl sheet, so it takes time and effort to remove the vinyl sheet suddenly by weather forecast such as wind and snow, and agricultural vinyl sheet by frost damage forecast. It is almost impossible to prevent sudden work such as sudden installation work, and there is no way to prevent it.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention aims to provide a roof sheet that can be easily stretched without a framework and can be easily stretched. Synthetic resin sheets other than vinyl sheets can also be used.

[0004]

[Means for Solving the Problems]

 In the present invention, a reinforcing band such as a flat cord or a piano wire is fixed at predetermined intervals in a predetermined direction of the synthetic resin sheet main body by means of welding or the like, and both ends of the reinforcing band are attached to the ends of the synthetic resin sheet main body. It extends from the edge to form a fixed part, and the synthetic resin sheet body forms an air chamber by welding a plurality of sheets at predetermined intervals to form an air chamber. The roof sheet has the reinforcing band also fixed thereto, so that these air chambers can be freely filled with air.

[0005]

【Example】

 The present invention will be described in more detail with reference to the illustrated embodiment. A reinforcing band 2 such as a flat string or a piano wire is provided at predetermined intervals in a predetermined direction of a synthetic resin sheet body 1 such as a vinyl sheet used for an agricultural vinyl house. Are fixed to each other by welding or the like, and both ends of the reinforcing band 2 are extended from the edge 1 'of the synthetic resin sheet main body 1 to form a fixing portion 2'.

When the reinforcing band 2 is made of a synthetic resin and made of a flat string, it can be fixed directly to the sheet body 1 by welding or the like. However, in the case of a piano wire or the like, the sheet is covered with the piano wire via a welding cloth. Welding with the main body 1.

[0007] The length of the sheet body 1 is set to reach a substantially lower end in the shed direction of both ends to be constructed.

The synthetic resin sheet main body 1 forms air chambers 3, 3... By welding the sheets 1 ", 1" at predetermined intervals as double or triple sheets. The reinforcing strips 2, 2 are also fixed at required welding positions 3, 3,... So that air can be freely filled into the air chambers 3, 3,. General means such as welding and bonding may be used in accordance with the material of (2). If the reinforcing band is a metal such as a piano wire, an auxiliary cloth (not shown) may be welded and fixed so as to enclose the piano wire.

In the air chambers 3, 3,..., A hose 5 having dispersion holes 4, 4,... Is laid so that air flows smoothly, and the air chambers 3, 3,. The base end of the hose 5 of each of the air chambers 3, 3,... Is connected to an air supply pipe 6 via a valve (not shown). Is free.

The synthetic resin sheet main body 1 can be arbitrarily used in a transparent, translucent or opaque manner according to the purpose of use, and the color and the like can be freely selected.

[0011]

[Action]

 Although the present invention is as described above, the single sheet body 1 is mainly used in places other than snowy countries, and the sheet 1 "is doubled and tripled, and the air chambers 3 and 3 are provided. Is mainly used in snowy countries, but may be used elsewhere.

As a specific usage method, a plurality of corresponding columns 8, 8... Are erected, and a wire 9 is stretched between the corresponding columns 8, 8 with a difference in height. The fixing sheet 2 'projecting from both ends of the synthetic resin sheet 1 is fixed to an anchor 13 fixed in the ground or the like, and the reinforcing band 2 is stretched. Adjacent roof sheets shall be stretched with their side edges overlapped.

When a garage or the like is to be made along with an existing building or the like, as shown in FIG. 5, a support member 12 such as an angle, a timber, a pipe, or the like is fixed to the building 11 while the building 11 is attached to the outside of the building. , A wire 9 is stretched opposite to the supports 8, and one fixing portion 2 ′ of the reinforcing band 2 is fixed to the support member 12, and the other fixing portion 2 ′ is fixed to the anchor 13 or the like.

When a round or triangular roof is made, a round or triangular beam 10 (FIGS. 6 and 7) is made of pipe, H-section steel, etc. It is erected, a wire 9 is stretched at a required position of the beam 10, a roof sheet of the present invention is put on the stretched wire 9, and the fixing portion is fixed to an anchor or the like to reinforce. Stretch a belt.

Although not shown, fixing portions 2 ′ at both ends of the roof sheet of the present application are fixed to anchors and the like, and a floating object such as an ad-balun is tied to the center so that only the center is fixed. Elevated temporary roofs can be easily made.

When an air chamber 3 is used, the degree of air filling when snow accumulates can be adjusted so that snow can be easily dropped, and damage due to weight can be minimized. It can be stopped, and when used in a cultivation house for agriculture, etc., it is excellent in heat insulation and heat insulation, suitable for growing plants, and when used as a temporary roof for event venues etc. It becomes something.

[0017]

【effect】

 As described above, in the present invention, a reinforcing band such as a flat string or a piano wire is fixed at predetermined intervals in a predetermined direction of the synthetic resin sheet body by welding or the like, and both ends of the reinforcing band are bonded to the synthetic resin sheet. Since it is extended from the edge of the main body and used as a fixed part, it can be hung on a wire stretched between the columns, the fixed part can be easily stopped and the roof sheet can be stretched, and also removed. In this case, it can be removed by a simple operation that only releases the fixing part, and damage due to wind damage can be minimized.

In the synthetic resin sheet body, the sheets are welded at predetermined intervals with a plurality of sheets to form an air chamber, and the reinforcing band is also fixed to a required welding position of the air chamber. Since the air chamber can be freely filled with air, by adjusting the degree of air filling during snowfall, the snow on the roof sheet loosens and becomes more likely to fall along the slope, causing snow to fall. The roof sheet can be prevented from being damaged, the heat insulation effect is good, and it is excellent in agricultural economy when used as an agricultural house. Of course, the work of stretching and removing can be easily performed.
