Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure of a prefabricated hip roof used in prefabricated houses, etc., and its construction method.

[Prior Art] In recent years, various types of prefabricated prefabricated houses called "free-style" houses have been supplied in place of uniform and standardized wooden houses. Along with this, various variations (patterns) of roof shapes are being constructed, which determine the style of a house.

There are various roof shapes mentioned above, among which:
For example, when assembling the roof of a hipped structure of a prefabricated house, at the construction site, multiple rafters are installed vertically and horizontally on the ceiling of the first and second floors to form a roof frame. A method of constructing a hipped roof is to install a plurality of roof panels in a tilted manner on top of the roof, join the roof panels to the roof frame, and join the roof panels arranged side by side to each other.

[Problems to be Solved by the Invention] However, in the construction method described above, the roof panels are constructed one after another after forming the roof frame on the ceiling, so it takes a lot of time to work on site. It takes a lot of time and requires skilled workers, which can lead to longer construction times and higher costs.

Furthermore, assembling the roof is, of course, a high-risk task as it involves work at a high location within a building, and work at a high location requires construction time, which can easily result in exposure to rain etc. during construction. The problem was that it was difficult to ensure stable quality.

Therefore, as a result of intensive research to solve these problems, the inventor of the present invention constructed a roof with a plurality of roof units that integrated roof panels and the upper part of the roof frame, etc., and combined these plural roof units. They came up with the idea that if the roof was constructed using the same methods, on-site work would be easier, and construction time could be shortened and quality improved.

However, the reality is that such an effective and appropriate roof structure has not yet been developed.In particular, even if the roof is divided into multiple roof units, the assembly procedure of the roof units becomes complicated and This increased the number of joints between roof units that needed to be waterproofed, and there was a risk that the structure would be prone to leaks.

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a prefabricated hip roof structure and its construction method that can save labor and shorten the construction period at a construction site.

[Means for solving the problem] Claims of the present invention! The structure of the prefabricated hip roof described is a hip roof structure that has downwardly sloping roof surfaces on all four sides, front, rear, left, and right, and corner ridges at the joints of the front, rear, left, and right roof surfaces. The roof consists of a large ridge roof unit whose roof forms the left and right roof surfaces of the main ridge, and a plurality of corner ridge roof units that are located at the front and rear of the main ridge and form a corner ridge when combined. The roof unit is formed by integrating two roof panels into a mountain shape with their upper ends abutting each other, and the corner roof unit has a triangular shape at the top of the frame corresponding to the slope of the roof surface. The roof panel is characterized in that it is formed by joining a frame body and a roof panel in a tilted state.

The method for constructing a prefabricated hipped roof according to claim 2 is to construct a hipped roof that has downwardly sloping roof surfaces on all four sides, front, rear, left, and right, and has corner ridges at the joints of the front, rear, left, and right roof surfaces. In the method, at least one large ridge roof unit is provided in the center of the upper part of the wall, in which two roof panels forming left and right roof surfaces are integrated into a mountain shape with their upper ends abutting each other.
