Many of the foundations for fixing the equipment stand installed on the flat roof are made of concrete, and in that case, there is a problem that the load on the roof surface increases.
In addition, in the case of the above-described deck base roof, it is difficult to construct a foundation for fixing the mount on the waterproof sheet. In the deck base roof, when the air conditioning equipment or the solar power generation equipment is installed on the outer heat insulating roof, the base foundation stands up from the deck base or the roof beam, so the base foundation penetrates the waterproof sheet. Therefore, there are concerns about securing waterproof performance. If the pedestal foundation is installed on the waterproof sheet on the deck base roof, the heat insulating material disposed under the waterproof sheet on the metal base is recessed due to the weight of the pedestal base, and the pedestal foundation sinks. In addition, the deck base roof in the proposed example is intended for reuse, and when a foundation is added, a new structure that can be reused in a form that includes the foundation is required.

  An object of the present invention is an outer heat insulating roof provided with a heat insulating material and a waterproof sheet on a roof base, to reduce an increase in load on the roof surface, and to ensure waterproof performance, such as solar power generation equipment and air conditioning equipment. It is intended to provide a roof mounting structure that can stably mount a roof mounting structure.

  The roof mount installation structure of the present invention has a head and a plurality of legs extending downward from the head in a roof in which a heat insulating material is provided on an upper surface of a roof base and the heat insulating material is covered with a waterproof sheet.

Moreover, since it is comprised with a receiver, a raising base, and a fixed rail, unlike a concrete frame foundation, it can be made lightweight. In this way, in an outer heat insulating roof with a heat insulating material and a waterproof sheet provided on the roof base, the load on the roof surface is reduced and waterproof performance is secured, so that a stand for solar power generation equipment, air conditioning equipment, etc. Can be installed stably.

In the present invention, the roof base is a deck plate, the receiver is disposed on the top surface of the wavy portion of the deck plate, and the grip mounting head of the fixed rail is in a ridge direction of the wavy portion of the deck plate. It may extend along.
In this configuration, because the roof is a deck base roof, even if it is intended for reuse that is manufactured in the factory, the gantry can be installed at the pre-production stage, and the entire roof including the gantry can be installed. Reusable.

  In the present invention, the roof base may be an ALC plate, a reinforced concrete structure, or plywood. In other words, even if the roof is an outer heat insulating roof other than the deck base roof, it is possible to reduce the increase in load on the roof surface and secure waterproof performance, and to install a frame such as an air conditioning facility or a solar power generation facility it can.
