Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof support column that can stably support an inclined roof beam.

[Conventional technology]

BACKGROUND ART Conventionally, the inside of a house, particularly the attic of a house, is ventilated using, for example, a vent provided under the eaves, a vent such as a louver provided on the wall of a veranda, or the like. In addition, for attic ventilation, a dormer installed on a sloped roof or a chimney raised above the roof is sometimes used.

However, ventilation holes installed under the eaves and on the walls of verandas have been used frequently in the past, and do not add a new appearance to the house.Also, although ventilation holes are provided with rain protection such as louvers, they are relatively easy to remove from the wind. Rainwater easily enters the inside of the house, and although dormers improve the appearance of the house, similar ventilation holes are usually provided at the front facing the eaves.
It becomes difficult to prevent the intrusion of rainwater caused by wind and rain, and as described above, the vents in all of the above-mentioned devices are formed so that they can be accessed from the outside, and the vents sometimes give a sense of discomfort.

Although a chimney-like structure may be provided with a small roof to cover its upper end, it is often not possible to reliably prevent rainwater from entering when rain is accompanied by wind.

Therefore, as shown in FIG. 1, the present inventor provided a roof structure C on the roof R with its top surface and circumferential side closed, and also provided the roof structure C with its interior and ridges. It has ventilation holes on the side facing the side and L
By adding a duct D that bends into a letter shape, we have devised a ventilation structure for a house that gives a new appearance, enhances the appearance of the house, and prevents rainwater from entering. Furthermore, such a roof structure C
It can also be used as a place to store the upper machine of a residential elevator, which has been increasingly used in houses in recent years, and by forming the top surface as a skylight W, it can also be used to provide light to the inside of the house.

[The problem that the idea attempts to solve]

However, since such a structure C on a house is provided so as to protrude from the roof, it is necessary to improve the mounting strength in order to increase wind resistance and to construct it with good construction.

On the other hand, for example, as schematically shown in FIG. 2, a frame J of such a roof structure C is fixed onto a roof beam B of a roof R. however,
As illustrated in FIG. 8, for example, the load acting on the vertical member 11 on the eave side can be carried by the support piece 5 by providing the vertical member 11 on the support piece 5 at the eaves. The load acting on the side vertical members 12 directly applies bending force to the roof beam B, reducing the strength of the roof beam B and also reducing the attachment strength of the roof structure C.

The present invention aims, for example, to provide a novel roof support column that can firmly support the lower surface of an inclined roof beam that receives such a roof structure and can meet the above requirements.

[Means to solve the problem]

The present invention includes a lower fixing piece at the lower end that is fixed to the horizontal beam of the main body of the house, a tapered part whose width increases upwardly at the upper end, and a flat plate-shaped part at the upper end of the tapered part. This roof support post is provided with an upper fixing piece bolted to the lower surface of the roof beam, which has the same inclination as the lower surface of the sloping roof beam forming the roof covering the main body of the house.

[Effect]

The roof support beam has a lower fixing piece at its lower end and a flat plate-like upper fixing piece having the same inclination as the sloping lower surface of the roof beam at its upper end, so that it can reliably support the slanted lower surface of the roof beam. In addition, the roof support pillar has a tapered part that increases in width upward at the upper end, and the upper fixing piece is provided at the upper end of the tapered part, so the length of the upper fixing piece can be increased and the roof beam can be By supporting over a wide range, the load acting on the roof beam can be efficiently supported, which helps reduce the bending moment acting on the roof beam.

[Effect of idea]

In this way, the roof support column of the present invention has a lower fixing plate fixed to a horizontal beam at the lower end, and an upper fixing piece having an inclination along the lower surface of the roof beam at the upper end, thereby strengthening the roof beam. By connecting the roof beam to the roof beam, the load acting on the roof beam can be efficiently carried. Furthermore, since the upper fixing plate is provided at the upper end of the tapered part formed at the upper end of the roof support column and increasing in width in the upward direction, the upper fixing plate has a large width and can be attached to the roof over a wide area. Since the roof beams can be supported, the bending moment acting on the roof beams can be efficiently reduced and firm fixation can be achieved.
