Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet sticking-out feeding device for sticking a waterproof sheet to various waterproof target surfaces such as a roof of a reinforced concrete building by welding to cover the various waterproof target surfaces.

[0002]

2. Description of the Related Art For example, a waterproof target surface, which is a rooftop of a reinforced concrete building, needs to be covered with a waterproof sheet in order to obtain waterproofness. The waterproof sheets are roughly classified into those in which the surface of synthetic asphalt is covered with sand and those in which vinyl chloride is used.

As shown in FIG. 6, in the former waterproof sheet B, the back surface of the synthetic asphalt is melted by heating, and the edges b are welded so as to overlap each other. Then, the waterproof sheet B is welded to the waterproof target surface A through the primer applied to the waterproof target surface A, and is directly welded to the adjacent waterproof sheet B. In this case, there are a method of welding the entire back surface of the waterproof sheet B and a method of partially welding the back surface.

In the former method, synthetic asphalt is exposed on the entire back surface of the waterproof sheet B. Then, while the front side of the waterproof sheet B is in a wound state, the back side of the synthetic asfast of the wound waterproof sheet B is fed out while being melted by the flame ejected from the gas burner over the entire length in the width direction, and is pressed from the front side to be waterproofed. When facing only A, this waterproof surface A is adjacent, and when facing waterproof surface A and edge b of the adjacent waterproof sheet B, this waterproof surface A is adjacent. It is welded to both the edge portion b of the waterproof sheet B at the same time.

In the latter method, the synthetic asphalt is exposed over the entire length of the edge portion b on the back surface of the waterproof sheet B, and the synthetic asphalt is provided at a large number of inner portions at desired intervals and in desired sizes. Expose. Then, first, while exposing the exposed portion of the synthetic asphalt scattered in the width direction of the back surface of the waterproof sheet B in the wound state with the back surface side as the outside, while being fed out while being melted by the flame injected from the gas burner, the front surface side is pressed,
Welds only on the surface A to be waterproofed. Next, while the synthetic asphalt exposed on the back surface of each edge b is melted by the flame ejected from the gas burner and pressed from the front surface side to be welded on the waterproof surface A, or when there is the adjacent waterproof sheet B, The synthetic asphalt on the surface of the edge b of the waterproof sheet B is melted at the same time as the above-mentioned melting, and is welded on the edge b.

On the other hand, the latter waterproof sheet is pressed from the front side while melting the back surface thereof with hot air, and is applied to the waterproof target surface A or the waterproof sheet adjacent to the waterproof target surface A as in the former waterproof sheet B. Weld on both sides with the edges.

Conventionally, in order to weld or partially weld a waterproof sheet as described above, an operator faces forward and backward of the waterproof sheet with respect to the unwinding direction of the rolled waterproof sheet, and holds it in one hand. While heating and melting the backside of the tarpaulin with the flames jetted from the gas burner, he pulls the tarpaulin with the pull rod in his other hand, and rotates it out. Alternatively, the operator faces forward with respect to the unwinding direction of the rolled-up tarpaulin behind the tarpaulin, and the flame ejected from the gas burner in one hand heats and melts the backside of the tarpaulin while melting the other hand. Press the tarpaulin with, or press the tarpaulin with your feet,
It is rotating and feeding.

In the former method of sticking, the worker does not step on the waterproof sheet fed out after heating except in the case of a building, so that the finish is improved in this respect. However, it is difficult to straighten the waterproof sheet, and the finish is still poor. In addition, since the position of the flame injected from the gas burner is close to the worker, the flame may burn the hem of the pants and the shoes, which is not only dangerous, but especially scares beginners. Moreover, the work efficiency is poor because the work must be performed in a forward leaning posture. Further, it is difficult to work on an uphill or a downhill. On the other hand, in the latter sticking method, there is no danger of burning the hem of the pants or shoes due to the flame, and safety can be improved. However, it is difficult to work out the waterproof sheet in a straight line, and moreover, the worker steps on the waterproof sheet, which is unrolled after heating, over almost the entire length, so that the finish is poor. Moreover, the work efficiency is poor because the work must be performed in a forward leaning posture. Further, it is difficult to work on an uphill or a downhill.

In order to solve the above-mentioned problems of safety and work efficiency due to manual work, the truck is conventionally melted by heating and melting the back surface of the waterproof sheet which is wound by the flame injected from the gas burner parallel to the truck. There is provided a waterproof sheet attaching device that pulls out a waterproof sheet.
