Description

  The present invention relates to a technique for installing a tension device for hooking a rope, wire or the like on an existing waterproof layer such as a rooftop or a flat roof, and in particular, a novel tension device, and maintains a strong waterproof property using the tension device. The present invention relates to a tensioning device mounting structure on a waterproof layer and a tensioning device mounting method.

When some work is required on the existing waterproof layer laid on the rooftop, flat roof, balcony, etc. of the building, the work itself or work materials are locked, or the antenna, pole, etc. are fixed In many cases, a fulcrum or a base for hanging is required.
Such a fulcrum or base needs to be firmly fixed to an anchor bolt or the like driven into the base including a waterproof layer from the viewpoint of safety.

However, it is actually very difficult to drive anchor bolts or the like into the base through the waterproof layer. The reason for this is that it has been conventionally contraindicated to perforate holes in any form in the existing waterproof layer because it may impair the waterproof reliability. Therefore, conventionally, when any fulcrum or base or the like is required on the waterproof layer, a method of installing and fixing the waterproof layer including these on the base before forming the waterproof layer is employed. For this reason, there was no freedom of installation location, and it was not possible to install it where it was necessary.

The technology related to the present invention is disclosed in the following document.
