Abstract

PURPOSE: To increase strength by disposing a reinforcing material reinforcing an existing roof backing and an existing roof material on an existing roof and forming a new roof material consisting of a stepped roofed-shaped roof material on the reinforcing material. CONSTITUTION: Reinforcing materials 4 composed of a narrow long-sized sheet- shaped steel material, etc., are disposed and fixed on an existing roof material B on a roof backing A made up of rafters 1, a batten 2, an asphalt roofing 3, etc., at proper pitches. Backing materials D consisting of a gypsum board, an ALC board, etc., are superposed on the reinforcing materials 4, and fixed so as to form triangular voids β in a stepped shape. New roof materials C composed of a stepped roofed-shaped roof material formed in a long-sized board shape by roll molding, press molding, etc., are roofed on the backing materials D. Accordingly, the execution of works is simplified, and cost can be curtailed.

However, in such a refurbished structure, it is necessary to replace an old roof material with a new roof material by replacing the old roof material with a new roof material on a damaged existing roof material. Only the technical idea of hiding the roof was taken into consideration, and the technical idea of reinforcing the existing roof substrate, the skeleton or the existing roofing material of an old building to improve the strength was not taken into consideration at all. For this reason, the roof underlayment and the structure of the building after the repair are burdened, and the strength is weak, especially the earthquake resistance is extremely inferior, the new roofing material is dropped due to the occurrence of an earthquake, etc. However, there were cases where damage such as the collapse of buildings occurred.

As described above, according to the roof repair structure of the present invention, the conventional drawbacks can be solved and the existing frame,
Since the existing roof base and the reinforcing material that reinforces the strength of the existing roof material are arranged on the existing roof material, the strength of the entire building is improved and the structure is strong against earthquakes. Since it is not necessary to dismantle the existing roofing material, the number of construction steps can be omitted, the construction period can be significantly shortened, and there is no hindrance to living during construction. Since the new roof material is formed directly on the existing roof material, the construction is easy and the cost can be saved.
Double wall structure of existing roof material and new roof material
It has a soundproof and fireproof structure. The new roofing material is fixed directly to the existing roofing base and does not easily fall off. There are characteristics and effects.
