Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of constructing a unit building having a pitched roof.

[Prior Art] In recent years, in the construction of houses, etc., unit buildings have become widespread, in which living rooms, dining rooms, bedrooms, and other living areas are pre-produced in factories as units for each living area, and these units are assembled adjacent to each other at the construction site. There is.
Unit buildings have the advantage of being manufactured in factories for quality control and cost reduction, as well as the ability to transport each residential unit individually.
It is possible to vary the adjacency and combination of each residential unit depending on the owner's requests and the environment of the construction site, so it has the great advantage of being able to provide homes with a variety of floor plans and sizes to the owner. has.

Incidentally, in the past, many unit buildings were of a flat roof type, with the upper surface of each residential unit having a rectangular parallelepiped shape being used as the roof surface. This is because it was considered most efficient in terms of ease of transportation and productivity to have a flat roof on the top of the living unit. However, unit buildings with flat roofs have a simpler exterior shape than conventionally constructed houses with pitched roofs, and they also have disadvantages in dealing with rain and snow. , unit buildings with pitched roofs are becoming more popular. To adopt a sloped roof in a unit building, residential units assembled in a rectangular parallelepiped shape are assembled adjacently, and a sloped roof is formed on-site on top of that, or a sloped roof is formed on the top of each residential unit.
This is done by arranging roof units each having a sloped roof surface. The roof slope plane of each roof unit arranged above each residential unit is preformed so that it is a continuous roof slope plane when adjacent, so that when the roof units are assembled, the roof slope plane is continuous from the top edge of the roof. This results in the formation of a unit building with a roof slope that descends.

However, in unit buildings where the combinations of residential units change in various ways depending on the client's requests and the environment of the construction site, in order to form continuous roof slopes, it is necessary to prepare the roof in a shape that corresponds to the combinations. It was necessary to prepare a roof unit with a sloped surface, which caused problems in terms of the number of parts and production control. For this reason, two or several types of roof units are commonly used, and by combining these roof units, it is possible to accommodate various combinations of residential units, and also to accommodate pitched roofs of various shapes such as square roofs and hipped roofs. It has been desired to develop a method for constructing a unit building with a pitched roof that can form a sloped roof.

[Object of the Invention] The present invention provides a simple and easy way to construct a unit building with a pitched roof by selectively arranging roof units A to C on top of each of residential units that are combined adjacently in various ways. To improve the appearance of a unit building by making it possible to provide a unit building with various roof shapes such as a rectangular roof and a hipped roof depending on the combination of each roof unit. It is an object.

Depending on the combination, it is possible to form various sloped roofs on unit buildings.

Furthermore, if the living units 1 are not only adjacent horizontally but also connected in the height direction, various possibilities can be created in a two-story unit building or a partial two-story unit building as shown in Figures 16 to 18. It becomes possible to construct a sloped roof.
