Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a roof structure which can be mounted on a roof of a house and used for ventilation, etc., to improve the mounting strength of the roof structure.

[Conventional technology]

Conventionally, the inside of a house, particularly the back of a house is ventilated using, for example, a vent provided under the eaves and a vent such as a louver provided on the wall surface of a verge. In addition, for ventilation of the attic, a dome installed on a sloping roof or a chimney raised on the roof is sometimes used.

However, the ventilation holes provided under the eaves and the wall surface of the keraba have been widely used from the past, and it is not possible to give a new appearance to the house.Although the ventilation holes are provided with a shelter to prevent rain, it is relatively easy with the wind. Rainwater easily enters the interior of the house. Moreover, although the one using dorma enhances the appearance of the house,
Usually, a similar vent is provided on the front facing the eaves, making it difficult to prevent rainwater from entering due to wind and rain,
As described above, in any of the above-described cases, the vent hole is formed so that it can be seen from the outside, and the vent hole sometimes gives a feeling of strangeness.

Although the chimney-shaped one is provided with a small roof covering the upper end of the chimney-shaped one, similarly, it is often impossible to reliably prevent the intrusion of rainwater during rainfall accompanied by wind.

Therefore, the inventor of the present invention, as shown in FIG. 1, provides a rooftop structure C having a closed upper surface and a peripheral side surface on the roof R, and the rooftop structure C is provided inside and on the ridge side. A ventilation structure for a house that has a ventilation port on its side facing toward the side and uses a duct D that is bent in an L shape to give a new appearance, enhance the appearance of the house, and prevent rainwater from entering. Devised. In addition, such a roof structure C
Can be used as a place for housing an upper machine of a domestic elevator that is being adopted in a house in recent years, and by forming the upper surface as a skylight W, it can also be used as a light to the interior of the house.

[Problems to be solved by the device]

However, since such an on-roof structure C is provided so as to project on the roof, it is necessary to improve its mounting strength in order to increase wind resistance.

An object of the present invention is to provide a roof structure capable of firmly fixing a rooftop structure that can be used for ventilation.

[Means for Solving the Problems]

The present invention is a roof structure in which two roof beam bodies E, which are bridged in parallel between the parallel beams M, M, and an on-roof structure C are mounted on the roof beam bodies E, wherein the roof beam body E is a pillar piece.

Each of them is a roof pillar (2), (2) standing upright with side beam pieces (6), (6) facing each other, and a pair of ridge side beam pieces (7), (7) tilting downward, respectively. The eaves-side beam piece is joined to the eaves-side beam pieces (6) and (6) at one end and bolted to the other ends of the ridge-side beam pieces (7) and (7). (6), which is composed of a V-shaped beam (3) bridged between (6), and the eaves-side beam piece 6 and the ridge-side beam piece 7 are shaped steel members having the same cross section in which flanges are provided above and below the web. Consists of or The other end of the eaves-side beam piece (6) and the other end of the ridge-side beam piece (7) are connected to each other by using a joint metal fitting (20) fitted and bolted to the groove formed by the web and the upper and lower flanges. While being bolted, the roof structure C has two eave-side vertical members (11),
(11) and the vertical members (11) on the eaves side, two vertical members on the ridge side that are located at a higher position than the vertical members (11) and (11) that face the eaves in the inclination direction. Material (12), (12),
The vertical members (12), (15) having joint materials (13), (14), (15) arranged between the eaves-side and ridge-side vertical members (11), (12). 12) Mounting pieces (23), (23) provided at the lower end and inclined at the roof inclination angle
Of the roof beams E, E extending from the eaves-side beam pieces (6) of the roof beams E to the ridge-side beam pieces (7) over the other end, and is mounted on the upper surface of the upper flange and bolts. The roof structure C is attached to the roof beams E, E by stopping, and the roof beams are attached to the two horizontal and parallel beams N, N connecting the beams M, M below the roof beams E, E. The bundles (4) and (4) are respectively erected, and upper fixing pieces (27) and (27) inclined at the inclination angle of the roof are provided at the upper ends of the bundles (4) and (4), and the upper fixing pieces (27) and (27) are provided.
