Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of a unit type building, and more particularly, in a unit type building subject to diagonal line restriction, both a flat roof surface and a sloping roof surface are formed on the upper part of the main body of the building. The present invention relates to a roof structure of a unit-type building that satisfies the diagonal line limitation and can effectively utilize the roof surface.

[0002]

2. Description of the Related Art Conventionally, a unit type building formed by combining building units and roof units manufactured in a factory in advance at a construction site has been used. The planar dimensions of these building units and roof units are modular,
By placing one roof unit on one building unit, a structurally strong building is formed as a whole.
According to such a unit type building, there is an advantage that the work at the construction site is reduced and the construction is completed in a short period of time.

On the other hand, three-story unit-type buildings have been built for the purpose of effectively utilizing a small site, and furthermore, a flat roof surface is formed on the upper part of the main body of the unit-type building. The rooftop space is effectively used by arranging a solar unit and an outdoor unit of an air conditioner on this flat roof surface, or by setting it as a walking roof surface.

By the way, when a flat roof surface is used as a walking roof surface, a stair for raising and lowering is provided in the building body,
The doorway must be installed on a flat roof surface. In this case, a penthouse having an opening serving as an entrance / exit must be provided on the flat roof surface.

[0005]

However, a three-story unit-type building provided with such a flat roof surface may be subject to oblique line restrictions due to the relationship with adjacent land boundaries or road boundaries on the construction site. Yes, to meet this limit,
It was necessary to provide a sloping roof on a part of the roof of the unit building.

Further, the position of the stairs for raising and lowering to reach the rooftop differs depending on the arrangement of the building units and the inclination of the stairs for raising and lowering, and the stairs for raising and lowering are not always attached to a predetermined position of one building unit. Accordingly, the position of the penthouse unit does not always fit in a predetermined position above the building unit, and in some cases, it may be arranged across two building units. In such a case, if a special penthouse unit is manufactured for each building according to the position of the penthouse, there is a problem in that the manufacturing cost increases and the manufacturing process becomes complicated.

A first object of the present invention is to provide a roof structure of a unit type building which does not increase the manufacturing cost of a penthouse unit provided as an entrance when a flat roof surface is used as a walking roof surface. A second object of the present invention is to provide a roof structure of a unit type building having a flat roof surface, which can be easily accommodated within a diagonal line limit.

As described above, according to the present invention, even if the arrangement of the building units constituting the main body of the building and the inclination of the stairs for raising and lowering are different, the position of the penthouse is changed accordingly. Since they can be joined, the members that construct the penthouse can be shared, and the manufacturing cost of the penthouse unit does not increase. Further, by arranging the trapezoidal unit on the outdoor side edge of the upper part of the building body subject to the diagonal line restriction, the vertical position of the sloping roof surface can be lowered. As a result, the building itself can be placed closer to the adjacent land boundary line or road boundary line,
It is easy to fit the building body within the slanted line limit.
