That is, the exterior structure holds the roofing sheet by fixing the connecting material on the base, but the connecting material can be fixed only after the roofing sheet is laid. Until the connection material is fixed, the shingle is simply placed on the base. Generally, in this type of vertical roofing shingles used for medium and large-sized properties exceeding the size of private houses, long vertical roofing shingles are applied, so the length is short, about 10 m, and long It is 40, 50 m or more, and the weight is large. For this reason, many workers cooperate with each other at intervals of about 3 m to lay the shingles. Then, after placing the roof shingle at a predetermined position on the groundwork, most workers who worked together until then moved away from the roof shingle, for example, to move on to the next roof laying work, The shingle is simply placed on the base. Since this roof shingle has a large area and is likely to be subjected to wind pressure, there is a possibility that the roof shingle may be thrown up by a gust, be turned up, cause an accident to fall outside, or cause a physical injury such as a fall of an operator. Further, even if the accident does not occur, if the number of workers is small relative to the length of the shingle, local deformation of the shingle may be required and its correction may be necessary, or a position adjustment for mounting may be performed. As a result of the time required for (operation for adjusting to the marking line), an unexpected delay may occur in the operation process.
