Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dome having a roof having an arcuate shape, which can be formed by using a sash having a pentagonal sash frame to improve construction efficiency and reduce costs.

[0002]

2. Description of the Related Art In recent years, a dorma that can improve the appearance of the house by changing its appearance for ventilation and lighting is widely used, and as such a dorma, a sloping roof of the house is used. It is generally known to have a double-flowing dorma roof whose inclination direction is different from that of the right angle.

On the other hand, a dormer in which a dormer roof is formed into an arc shape is becoming popular in order to improve the appearance and enhance the design.

[0004]

However, in the case of a dormer having an arc-shaped dormer roof, the constituent members forming the dormer roof are rather complicated, which lowers the construction efficiency on site and causes the member to be damaged. As the cost increases and the upper frame of the sash arranged on the front surface of the dormer has an arc shape, it is difficult to manufacture the sash, and there is a problem that the manufacturing cost is significantly increased.

According to the present invention, a dome body having a front frame body forming a pentagonal space by a pair of front pillars and a dormer roof beam arranged at the upper end of each front pillar extends in an arc. Basically, a roof panel is arranged and a sash having a pentagonal sash frame is arranged in the space of the front frame, so that the structure of the dome roof can be simplified, the construction efficiency is improved, and the member cost is reduced. In addition, it is possible to form the upper portion of the sash frame in a C-shape, and it is an object of the present invention to provide a dormer that can easily manufacture the sash and reduce the cost.

[0006]

DISCLOSURE OF THE INVENTION The present invention is directed to a sloping roof, which has a pair of front pillars which are erected on the roof plate of the sloping roof and spaced at right angles to the flow direction, and the upper ends of the front pillars. in the front frame member forming a pentagonal space together with inclined roof with a dormer roof beams disposed in Ha-shaped, dormer purlins extending from the intersection of the dormer roof beam of the front frame to the sheathing roof board in the horizontal and rearward, contact
And a dorma having a dorma eaves beam horizontally and rearwardly extending from the upper end of the front pillar of the front frame to the field plate, wherein one dome eaves beam is placed on the upper surface of the dorma body to the other arranged for dormer eaves beam roof panel forming the roof of the Katsu Nobi dormer body in an arc over the dormer purlin up, and in the space of the front frame, 5 having a c-shaped portion at the top by catch the air A sash having a rectangular sash frame is arranged, and at the front surface of the front frame body, the front edge of the arc-shaped outer cover portion connected to the roof panel is hung from the front edge to cover the c-shaped portion of the sash. A front cover that curves in an arc is provided.

[0007]

The roof of the dome body is formed by a roof panel which is placed on the upper surface of the dome body and extends from one dome eave beam to the other dome eave beam in an arc over the dormer purlin. Therefore, the arc-shaped dome roof can be easily formed by attaching the roof panel, the construction efficiency at the site can be improved, and the member cost can be reduced.

In addition, a sash having a pentagonal sash frame having a C-shaped portion at the upper portion by arranging a shape in the space is arranged in a pentagonal space formed by the front frame of the dormer main body. As described above, since the sash does not have an arcuate upper portion but a pentagonal one having the above-mentioned C-shaped portion, its manufacture can be facilitated and the manufacturing cost can be greatly reduced.

Further, the C-shaped portion of the sash is covered with a front cover that is hung from the front edge of an arc-shaped outer cover portion connected to the roof panel and that is curved into an arc. Therefore, 5
Even when a square sash frame is used, the appearance from the front of the dormer is arcuate because the c-shaped part is blindfolded by the front cover, and the arcuate dome roof is low-cost without impairing the appearance. Can be formed.
