DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a synthetic resin corrugated sheet which is applied to a roof of a greenhouse, for example, in which a plurality of synthetic resin corrugated sheets are arranged in parallel along a horizontal direction. .

[0002]

2. Description of the Related Art When roofing a greenhouse or the like with a strip of synthetic resin corrugated sheet wound in a coil shape, a plurality of corrugated sheets are horizontally moved from the eaves to the ridge one step at a time. It is common to lay in parallel along with one side edge.

That is, as shown in FIG. 5, a first-stage synthetic resin corrugated sheet (1) wound in a coil shape is fixed to the roof structure (3) with its ends fixed to the eaves tip. And lay it down, and fix the unwinding area to the roof structure (3). Next, as shown in FIG. 6, a second-stage synthetic resin corrugated sheet (2) wound in a coil shape is attached to the lower part of the end portion of the upper part of the first-step corrugated sheet (1). And the overlapping area is fixed to the roof structure (3) and rewound, and the lower edge of the second-stage corrugated sheet (2) is attached to the first-stage corrugated sheet (1). ), And the second-stage corrugated sheet (2) is fixed to the roof structure (3). Further, the next-stage corrugated sheet is laid so as to overlap with the upper edge of the second-stage corrugated sheet (2), and thus the corrugated sheets are successively arranged one by one up to the ridge of the roof structure (3). Laying.

[0004]

The corrugated sheets (1) and (2) made of synthetic resin are made of an elastic material such as polycarbonate or vinyl chloride, for example. The lengths of the corrugated sheets (1) and (2) have some variation depending on the manufacturing conditions, and the pitch between the peaks and the valleys differs depending on the individual corrugated sheets (1) and (2). .

Therefore, as shown in FIG. 7, for example, when the pitch of the first-stage corrugated sheet (1) is smaller than the pitch of the second-stage corrugated sheet (2), ) End (2a)
Is positioned and fixed with respect to the end (1a) of the first-stage corrugated sheet (1), and then the second-stage corrugated sheet (2) is set with its lower edge at 1
When rewinding so as to overlap the upper edge of the corrugated sheet (1), the second corrugated sheet (2) is gradually displaced with respect to the first corrugated sheet (1). . In this case, if the second-stage corrugated sheet (2) is forcibly overlapped and fixed on the first-stage corrugated sheet (2), the second-stage corrugated sheet (2) is placed between the fixed positions. It rises from the corrugated sheet (1) and a gap is formed between the two corrugated sheets (1) and (2), which not only impairs aesthetic appearance but also causes water leakage such as rain leakage. This is not limited to the problem between the first-stage and second-stage corrugated sheets (1) and (2), and the same applies to the third-stage and subsequent corrugated plates.

Therefore, in the conventional corrugated sheet construction method, the first-stage corrugated sheet (1) is laid so as to be stretched and fixed in this state, so that the pitch of the first-stage corrugated sheet (1) is 2. The pitch of the corrugated sheet (2) after the second step is set longer than the pitch of the corrugated sheet (2) after the second step, and the corrugated sheet (2) after the second step is laid while extending all the time. Although it is made to overlap without gaps along the corrugated sheet (1), the amount of extension of the corrugated sheet (1) and the amount of tension are delicate, and the amount of extension is set based on the experience and feeling of the worker in many cases. As a result, there was a problem that implementation was difficult.

The present invention solves the above-mentioned problems of the prior art, prevents a gap from being formed between corrugated sheets, ensures a good appearance, and prevents water leakage such as rain leakage. An object of the present invention is to provide a method of installing a synthetic resin corrugated sheet that can be easily performed.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to one of a plurality of synthetic resin corrugated sheets, each of which is wound in a coil shape and which is corrugated in the longitudinal direction. After laying and fixing the corrugated sheet on the building structure while rewinding the corrugated sheet on the second step,
In the method for constructing a synthetic resin corrugated sheet in which one side edge is rewound so as to be superimposed on one side edge of a corrugated sheet in the previous stage and fixed to the building structure, the corrugated sheet is constituted by a rod extending linearly. In addition, a wavy surface having a pitch equal to or longer than the longest pitch among the pitches between the peaks of each of the plurality of corrugated sheets is wavy in the bar longitudinal direction on at least the peripheral side surface thereof. While fixing the corrugated sheet reference member formed in the above, before fixing the first-stage corrugated sheet to the building structure, the corrugated surface of the corrugated sheet reference member is changed to the first-step corrugated sheet. The corrugated sheet is stretched by pressing the corrugated sheet against the plate so as to follow the corrugated surface without any gap, and in this state, the first-stage corrugated plate is fixed.

[0009]

According to the method of constructing a synthetic resin corrugated sheet of the present invention, a corrugated surface having a pitch equal to or longer than the longest pitch among a plurality of corrugated sheets is provided. When the first reference corrugated sheet is prepared and the first corrugated sheet is fixed, the corrugated surface of the reference corrugated sheet is pressed against the first corrugated sheet so that the corrugated sheet follows the corrugated surface without any gap. It is stretched out. For this reason,
The pitch of the fixed first corrugated sheet is equal to the pitch of the corrugated surface of the reference member for construction, that is, longer than the pitch of the corrugations laid on the second and subsequent steps, and the corrugated sheet of the second and subsequent steps Is stretched all the time, so that the second and subsequent corrugated sheets can be superimposed on the preceding corrugated sheet without any gap.
