[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a roof sheet (including a garment cloth and a light shielding sheet) tensioning structure for greenhouses, tents, fish farms, outdoor pools and the like. More specifically, the sheet of the roof can be opened by winding the sheet with a take-up rod, and the sheet of the roof can be re-expanded by rewinding with the take-up rod. It is related to the tension structure.

[0002]

2. Description of the Related Art In greenhouses and other greenhouses, one end of a seat fixed to a roof ridge or a sloped portion of the seat is extended in the downward direction and the other end of the seat rolls on the outer surface of the seat. A seat tension structure in which the winding rod is wound around and is detachably supported along the roof hem or the side of the house has been proposed by the inventor in Japanese Patent Publication No. 3-57265. ing. According to this sheet tension structure, when ventilation is performed for controlling humidity and temperature in the greenhouse, the winding rod is removed from the roof hem or the side of the house, and the winding rod is moved along the roof surface. When the roof sheet is opened by rolling in the winding direction of the sheet and the roof sheet is in the original stretched state, the winding rod is rolled in the opposite direction to move the roof hem or the house. It is fixed again to the side of.

FIG. 17 is a partial schematic view of the above-mentioned sheet-sheathed structure of a roof mounted on a vinyl house and seen from the top. As shown in FIG. 17, the end of the transparent vinyl sheet 3 on the ridge side a is fixed to the roof by a fixing member (not shown) parallel to the ridge, and the end of the roof hem side b thereof is fixed on the roof. It is wound around the take-up rod 4, and when the take-up rod 4 is turned as shown by the arrow a, the take-up rod 4 rolls so as to climb the roof surface, whereby the sheet 3 makes the take-up rod 4 ascend. It is wound around the winding rod 4 by the amount moved to. On the other hand, when the take-up rod 4 is turned as indicated by arrow B, the take-up rod 4 rolls down the roof surface, whereby the sheet 3 is re-roofed by the amount of the take-up rod 4 moving downward. Stretched on the surface.

[0004]

In the structure as described above, since the end portion 3a of the seat 3 which intersects the winding rod 4 at a right angle is not reinforced at all, the winding rod 4 is not reinforced. The sheet 3 deteriorates due to repeated winding and lowering, and tears and tears are likely to occur, and the sheet 3 may be torn from this portion. When the sheet 3 is a woven or knitted light-shielding sheet or frosted cloth, it begins to fray from the end of the sheet 3 on the gable side, and the fraying gradually progresses toward the center. FIG. 18 shows a comparative example in which the reinforcing portion is formed by stacking the tape 3b on the end portion of the sheet 3 of FIG. The apparent thickness of the reinforcing portion becomes larger than that of the other portions of the sheet 3 by overlapping 3a. When the reinforcing portion having such a large thickness is provided, as the sheet 3 is wound around the winding rod 4, the reinforcing portion has a larger winding diameter than other portions of the sheet, and thus the winding rod. Since the central portion of 4 is bent downward, the winding rod 4 eventually stops rotating and cannot be wound. It is an object of the present invention to provide a roof sheet configured to be able to be wound up and down by a winding rod as described above, so that the sheet can be smoothly wound by the winding rod and the sheet can be wound smoothly. It is an object of the present invention to provide a seat sheet tension structure for a roof that can prevent the roof from breaking and other deterioration.

A roof sheath according to the present invention
In order to achieve the above-mentioned object, the tot structure has a state in which one end is fixed to a roof ridge or an inclined part and the other end extending in the downward direction of the seat rolls on the outer surface of the seat. And in a structure in which the take-up rod is detachably supported in a state along the roof hem or the side of the house, at least at the portion closer to the wife side of the sheet. Is a cross section that obliquely intersects the winding rod when viewed from the top surface and that has a reinforcement portion that has a larger apparent thickness than the other portions of the seat in a state that extends from the roof hem direction to the ridge direction. is there.

The reinforcing portion may be formed by stacking a cloth or synthetic resin tape on the upper surface or the lower surface of the sheet, and a small diameter rope or string is fixed to the sheet. May be formed by
It can also be implemented by forming by folding. When a cloth or synthetic resin tape is laid on the upper or lower surface of the sheet, all or a part of the tape is adhered, fused, sewn or the adhesive tape. It can also be carried out by forming a sheath portion on the sheet and inserting a tape into the sheath portion. Further, the end portion of the seat on the end side is formed by cutting it so as to cross the winding rod obliquely as viewed from above, and the reinforcing portion is formed along the end portion of the sheet. You may form it.

[0007]

According to the seat tensioning structure of the present invention, since the end portion of the seat is provided with the reinforcing portion having an apparent thickness larger than that of the other portion of the seat, The reinforcing portion prevents the sheet from being deteriorated, and the sheet is not torn or frayed inward from the reinforcing portion. Also,
Since the reinforcing portion having a large thickness intersects the winding rod obliquely when viewed from the top surface and extends in the ridge direction from the roof hem direction, the reinforcing portion having a large thickness is used as the winding rod. When wound, the winding trace becomes spiral.
The reinforcing part does not wrap (does not overlap) even when wound up, or even if it is wrapped, a part of the reinforcing part only wraps a few times and the winding diameter of the part does not become so large. It doesn't become impossible.

FIG. 18 is a partial schematic view of the conventional example seen from the upper surface, and FIG. 18 is a partial plan view showing a comparative example with the sheet tension structure according to the present invention.

In FIGS. 1 and 3, reference numeral 1 designates a palm material 11 forming an upwardly gradual arc shape, a main material 12 fixed on the common material 11 at a predetermined interval, and a main material 12.
The roof frame 13 is composed of a roof frame 13 fixed on the upper part of the roof in a rafter shape at regular intervals, and the palm material 11 is supported by various columns 2.

A ridge member 14 is fixed on the pallet members of the pallet members 11, 11 and a fixing member 15 having a groove with a cross section is fixed on the ridge member 14 along the ridge direction. 3,3
Is a sheet stretched on the roof frame 13 in a state where the ridge-side end is fixed to the fixing member 15 and the end hung toward the roof hem is fixed to the winding rod 4. In this embodiment, a polyolefin-based transparent film having a thickness of about 0.1 to 0.2 mm is used. As shown in FIG. 2, the ridge-side ends of the sheets 3 on both sides of this embodiment are the fixing members 1 as shown in FIG.
It is fixed by stacking it on top of No. 5 and pressing it with a pressing plate 16 and screwing a screw screw 17 into a groove of the fixing member 15 at a predetermined distance from the pressing plate 16. As shown in FIG. 4, the other end of the sheet 3 is wound around a winding rod 4 together with a reinforcing portion 30 which will be described later, and has a slightly smaller diameter than the winding rod 4 and a deep arc-shaped cross section such as a groove. Clip 40 made of synthetic resin
It is fixed to the winding rod 4 by fitting.
Even in the portion where the reinforcing portion 30 is not provided, the clip 40 is fitted to the winding rod 4 at a predetermined interval in a similar manner to fix the sheet 3 to the winding rod 4. 7 is a fixed tension sheet fixed to the side of the greenhouse. As shown in FIG. 5, a pulley 41 is fixed to the take-up rod 4 at an end portion protruding from the gable side of the greenhouse, and one of the ropes (not shown) wound around the pulley 41 several times. By pulling one side downward, the winding rod 4 is configured to rotate in the pulled direction.

Therefore, when the winding rod 4 is rolled up along the slope of the roof, the sheet 3 is wound (raised) by the winding rod 4 to open the roof, and the winding rod 4 is wound. When sheet 4 is rolled down, sheet 3 is unwound (rolled down) and stretched on the roof as it was.

In this embodiment, a pocket member 5 having a substantially hook-shaped cross section is fixed to the skirt of the roof in parallel with the ridge and fixed downward, and the winding rod 4 is rolled upward along the slope of the roof. The sheet 3 is wound around the winding rod 4 in a reverse winding state so that the sheet 3 is tensioned on the roof by rotating in the opposite direction (counterclockwise in FIG. 1). The rod 4 is housed in the pocket member 5. Further, the winding rod 4 is urged in a direction in which the sheet 3 is wound into the pocket member 5 by a detachable spring 6 or a weight (not shown) to prevent the sheet 3 from being loosened. It is structured. The winding rod 4 of this embodiment is rotated in the clockwise direction from the state of the solid line housed in the pocket member 5 as shown in FIG.
When the winding rod 4 is further turned clockwise,
The sheet 3 is wound around the winding rod 4 while rolling on the slope of the roof. Further, if the winding rod 4 is stopped in the middle of the inclined surface of the roof and a load or tension is applied to both ends of the winding rod 4 in the sheet winding direction in that state, the winding rod 4 will be The sheet 3 is stopped at that position, and the sheet 3 is kept in a tensioned state while being wound up to the middle of the roof slope.

As shown in FIG. 5, the sheet 3 of this embodiment is cut in such a manner that the end portions on the respective end sides cross the winding bar 4 at an angle when viewed from the top surface. A reinforcing portion 30 having an apparent thickness larger than that of the other portion of the sheet 3 is formed so as to extend from the roof hem direction to the ridge direction along the end of the sheet. The reinforcing portion 30 of this embodiment is formed by simply stacking a polyolefin tape 31 having a width of 20 mm and a thickness of 0.5 mm on the sheet 3 as shown in FIG. The end on the ridge side is fixed to the fixing member 15, and the end on the roof hem side of the tape 31 is fixed to the winding rod 4 together with the sheet 3.

In the sheet 3 of the above-described embodiment, as described above, the tape 31 is provided at the end on the end side so as to obliquely intersect the winding rod 4 and to extend from the roof hem direction to the ridge direction. When the sheet 3 is wound by rolling the winding rod 4 in the ascending direction along the slope of the roof, the reinforcing portion 30 is partially overlapped with the reinforcing portion 30 as shown in FIG. It is wound while being wrapped, but since the number of wraps is small, the reinforcing portion 30
The wound portion of the sheet 3 is not so large as the other portions, and the sheet 3 can be smoothly wound up to the ridge. Even if the sheet 3 is repeatedly wound up and down, the reinforcing portion 30 prevents the sheet 3 from being deteriorated.

As described above, the tape 31 is overlapped and the reinforcing portion 3 is formed.
In the case of forming No. 1, when the stability is poor only by overlapping the tape 31 with the sheet 3 due to the material of the tape 31 or the like, the entire tape 31 or a portion at predetermined intervals is formed. It is preferable that the tape 31 is fixed to the sheet 3 by adhesive, heat fusion, sewn, adhesive tape, or by tape. Further, as shown in FIG. 9, the sheath 32 is formed on the sheet 3,
The tape 31 may be inserted into the sheath portion 32, or the tape 31 may be wound around the end portion of the sheet 3.

Instead of each of the above embodiments, as shown in FIG.
The reinforcing portion 30 can also be formed by folding the end portion of the gutter 3 on the end side. Even if the sheet 3 is simply folded, it can be sufficiently carried out by fixing the folded portion to the fixing member 15 and the winding rod 4 shown in FIG. When it is difficult to form, it is preferable to stabilize the entire folded portion or a portion at predetermined intervals by adhesion with an adhesive or an adhesive tape, fusion bonding, sewing, and the like.

Instead of each of the above-mentioned embodiments, for example, as shown in FIG. 10, a sheath portion 32 is formed on the sheet 3, and a small diameter rope 33 or a string is passed through the sheath portion 32 to form the reinforcing portion 30. It can be implemented even if configured. In this case, the rope 33
Instead of being inserted into the sheath portion 32, all or a portion at predetermined intervals in the lengthwise direction is fixed to the sheet 3 by adhesion with an adhesive material or an adhesive tape, fusion bonding, sewing, etc. Alternatively, the rope 33 or the string may be wound around the end of the sheet 3 to fix the sheet.

FIG. 11 shows an example in which the sheet-tensioned structure of the present invention is applied to a greenhouse with an arch type roof, and an arch type roof frame 18 is shown standing on the road surface at a predetermined interval. A sheet of fixing member 19 fixed to a roof frame 18 parallel to the ridge on both sides of the greenhouse is connected to each other with several main building materials.
Is fixedly tensioned, and the fixing tension sheet 35 is fixed to the fixing member 15 of the ridge and the fixing member 19 of the side portion on the roof portions on both gable sides c. In the example of this figure, the pocket member 5 of FIG.
Although not shown in the figure, the same end as the ridge in the ridge direction is fixed to the roof on the fixing member 15 of the ridge and the end on the hem side of the roof is fixed to the winding rod 4. To 3 is stretched. Normally, this sheet 3 is in a state in which a part of its end side c overlaps with the fixed tension sheet 35 and a part of its roof hem direction overlaps with the sheet 8. In the sheet 3 of this embodiment, the tapes 31 and 31 similar to those of the above embodiment are parallel to both ends of the sheet 3 close to the end side c so as to cross the winding rod 4 at an angle. Side by side, these tapes 3
1, 31 are adhered to the sheet 3 at predetermined intervals by the respective adhesive tapes 34 to form two parallel reinforcing portions 30, 30.

In the sheet tension structure of the embodiment shown in FIG. 11, repeated winding and lowering of the sheet 3 is likely to cause tears or the like on the wife side c of the sheet 3, but these tears are likely to occur. Does not proceed from the reinforcing portion 30 to the inner side portion, so that the deterioration of the sheet 3 can be prevented to that extent. Further, even if the portion of the seat 3 that is closer to the end side than the reinforcing portion 30 is deteriorated, it does not matter because the fixing tension sheet 35 is stretched below. Other operations and effects of the embodiment shown in FIG. 11 are almost the same as those of the sheet tension structure shown in FIG.

In the embodiment shown in FIG. 11, the reinforcing portion 30 can be constructed in the same manner as the example described with reference to FIGS. When the sheet 3 is folded to form the reinforcing portion 30 as shown in FIG. 13, for example, as shown in FIG. 14, the fixing portion 36 is formed at predetermined intervals by fusion, adhesion or the like, and the folded portion is formed. It is desirable to settle each other.

Instead of forming the reinforcing portion 30 as described above only on the end side of the sheet 3, as shown in FIGS. 15 and 16, for example, from the end on the roof hem side b to the ridge side a. When a plurality of reinforcing portions 30 extending to the end portions of the sheet 3 and diagonally intersecting the both end portions are formed on the entire surface of the sheet 3 in a zigzag shape (FIG. 15) or in parallel (FIG. 16), the sheet 3 becomes Not only is the part reinforced, but the entire surface is reinforced uniformly. The seam of this embodiment
The reinforcing portion 30 of the grate 3 can also be formed in the same manner as in the above-described embodiments.

In the sheet tension structure according to the present invention,
The reinforcing portion 30 may be inclined in either direction. In the above-described embodiment, the ridge-side end of the sheet 3 is fixed to the fixing member 15 of the ridge, but a similar fixing member is provided in the middle of the inclined surface of the roof so as to be parallel to the ridge. Alternatively, the upper end of the sheet 3 may be fixed. In this case, another sheet (not shown) is fixed between the ridge and the fixing member.
