Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention has a steel frame and a wooden side frame on the front surface, which is excellent in strength and can be increased in size, and its width can be freely adjusted. It relates to a dorma that can be used as a living room by increasing the degree.

[Conventional technology]

In the past, in order to enhance the appearance of the house by adding ventilation to the back of the hut, lighting the room below the sloping roof, ventilation, etc., a dome is sometimes used for the sloping roof. There is.

Therefore, such a conventional dormer is relatively small,
Greater strength is also not required and the skeleton forming the dormer is formed using a wooden frame.

On the other hand, in recent years, it has been desired to utilize a house space, especially an attic.

[Problems to be Solved by the Invention]

However, even in a house having a sloping roof with both flows, when the space under the sloping roof is small, the shack is conventionally left unattended or used only as a storage place for articles. It has not been.

Therefore, as a result of various studies on the effective use of the attic space in such a case, the present inventor has focused on the dorma that has been conventionally used for the attic ventilation, the lighting of the living room below, and the like. Notice that it can be used as a living room by forming a relatively large space under the sloping roof by using a steel frame instead of the wooden frame used in front of the conventional dormer. By doing so, we have completed a dome that has excellent strength and can be made larger.

However, in the dormer used in this way, its width changes depending on the arrangement of beam members and the like in the roof assembly. Therefore, when forming the front surface of the dorma using only the steel frame body, it is necessary to prepare a frame body for each varying width, increasing the types of the frame body, and reducing the labor for production, inventory, etc. It will be necessary.

An object of the present invention is to provide a dorma which has a steel frame body and wooden side frame bodies on both sides thereof on the front surface, which is excellent in strength and productivity and which can be relatively easily enlarged. .

[Means for Solving the Problems]

The present invention is a dormer that is arranged on a sloping roof with the front surface facing downward of the flow of the sloping roof, and is a pair of steel strut members and a steel slant member that extends obliquely upward from the upper ends of each strut member. And the upper end of the diagonal member is joined to form a chevron, and the lower end of the support member is horizontal and is lined up on both sides of the frame member fixed to the steel purlin. The dormer is characterized in that a wooden side frame body having a diagonal member arranged and continuous with the diagonal member of the frame body is provided on the front surface.

[Action]

The dormer includes a steel frame body composed of a pair of support members and a diagonal member arranged diagonally and in a mountain shape at the upper ends of the support members, and wooden side frame members on both sides thereof. As a result, the rigidity and strength of the dome skeleton is increased as compared with a domema using a conventional wooden frame, and the frame fixes the lower end of the strut member to the steel purlin. The strength and rigidity can be increased, and the size can be increased to the extent that a living room or the like can be formed in the attic.

The side frames on both sides of the frame are made of wood and can be easily manufactured to any desired size. Also, since the diagonal members are in line with the diagonal members of the frame, they can be placed on both sides of the frame to reduce the width. It is possible to form a dorma of any size. Therefore, the types of frame bodies are reduced and the productivity is increased.
