TECHNICAL FIELD OF THE INVENTION
The present invention has a structure in which a tetrahedron-type roof having another building in a direction orthogonal to the main building is disposed and fixed on a roof base of a main body roof having one main building. The present invention relates to a roof structure in a different part of a house having a roof.
[0002]
Problems to be solved by the prior art and the invention
As one of the roof structures of a house, there is a roof structure in which a different part of a main body roof having one large building such as a ridge roof, a gable roof, or the like is arranged by a roof construction method. The laying roof construction method is to construct a laying roof consisting of a tetrahedron having another building in a direction orthogonal to the large building at a predetermined position on the roof foundation of the main body roof.
The construction procedure of a conventional general placing roof is as follows. First, after the framework of the main body roof and the roof foundation have been constructed, of the three sides constituting the triangular frame of the bottom surface of the tetrahedron, two sides corresponding to two sides laid and fixed on the slope portion of the main body roof 2 For the valley of the book, the worker measures and measures the position where the laying is fixed on the roof of the main body. Next, a mark indicating the measured and measured position for laying and fixing is provided on the main body roof. Next, the two valleys are cut to a predetermined length, and one end of each valley is processed into a top-shape shape. Then, the two cut and processed valleys are laid and fixed on the roof foundation of the main body roof in accordance with the marks provided on the main body roof.
After that, the horizontal projection dimensions written in the design drawings are converted into gradient dimensions, and based on the converted dimensions, the frame structure of rafters, trusses, etc. in the two valleys laid and fixed on the main body roof The position ink is put on the position where the material is installed. Next, frame structural members such as rafters, trusses, etc., are installed in a state in which they are arranged at predetermined intervals in a direction orthogonal to the gradient direction of the main body roof in accordance with the position mark. Then, by placing a member that forms the laying roof surface on the skeleton of the laying roof, the laying roof can be configured.
[0003]
However, when the standing roof is configured by the above-described procedure, the worker performs the work such as measuring or cutting the valley in an unstable place on the roof, so that the posture of the worker becomes unstable, which is dangerous. .
Also, the work of laying the valley on the roof foundation of the main body roof and the work of placing the rafters and truss on the valley are not performed on the horizontal plane, but on the slope of the roof using a measure etc. Therefore, the horizontal projection dimensions written in the design drawings must be temporarily converted to dimensions with gradients, which is an operation that requires accuracy and clarity. It was a task that was easy to make mistakes.
[0004]
