The method of installing the waterproof sheet shown in FIG. 9 is a method corresponding to the installation structure 1 of the waterproof sheet (see FIGS. 1 to 5). That is, the method of installing the waterproof sheet is that when the roof R such as the tiled roof of the building H such as a detached house is damaged due to the influence of a typhoon or the like, a waterproof sheet such as a blue sheet is used as an emergency measure. It is a method of temporarily preventing rain leakage by covering with 20.

Specifically, the method for installing the waterproof sheet includes a distance / direction measurement step S10, a shape calculation step S20, a structure assembly step S30, and a structure installation step S40.

In the distance / direction measuring step S10, each of the distances and directions (horizontal angle / elevation angle) from an arbitrary position under the building H (above ground) to the plurality of feature points P on the roof R is measured using the surveying instrument M. It is a process to do.

The shape calculation step S20 is a step of calculating the shape of the roof R based on the distance and direction measured in the distance / direction measurement step S10 by using a well-known surveying method. By this shape calculation step S20, it is grasped whether the inclined surface R2 of the roof R has a 5-minute gradient or a 7-minute gradient.

The structure assembly step S30 is a step of assembling the structure S in which the waterproof sheet 20 is stretched around the frame 10 having a shape corresponding to the shape of the roof R calculated in the shape calculation step S20.

The structure installation step S40 is a step of covering the roof R with the waterproof sheet 20 by lifting the structure S assembled in the structure assembly step S30 from under the building H (above ground) and placing it on the roof R. The structure S is fixed to the roof R with a rope (not shown) or the like, if necessary.
