Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a roof structure mounting structure capable of improving the mounting strength of a roof structure for ventilation formed on a roof of a house.

[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, as shown in FIG. 1, the inventor of the present invention provides a rooftop structure C having a closed upper surface and a peripheral side surface on the roof R, and the rooftop structure C includes the inside and the ridge side. Ventilation structure for a house that has a ventilation hole on the side facing toward and has a new appearance by adding a duct D that is bent in an L shape, which can 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 mounting structure that can firmly fix a roof structure that can be used for ventilation.

[Means for Solving the Problems]

The present invention is a mounting structure for a roof structure, which is a box-shaped structure provided on a sloping roof R of a house and which mounts a ventilation roof structure C on the roof R, wherein the roof R is , A parallel roof beam B extending in the direction of its inclination,
B1 and horizontal joint beams S4 and S5 installed at right angles between the roof beams B and B1, and the rooftop structure C includes two eave-side vertical members (11),
(11) and the vertical members (11) on the eaves side, which are positioned higher than the vertical members (11), (11) and at the same distance as the distance between the connecting beams S4, S5, and the vertical members (11) on the eaves side. ), Two ridge-side vertical members (12), (12) facing the inclination direction to (11)
And a panel mounting piece (24) for mounting the panels P1 and P2, which are arranged between the eaves-side and ridge-side vertical members (11) and (12) and form the wall of the rooftop structure C, respectively. (1
3), (14) and (15), and at the lower ends of the eaves-side and ridge-side vertical members (11) and (12),
A flat plate-like mounting piece (17) that is tilted in the same manner as the roof R is provided, and this mounting piece (17) is located on the upper surfaces of the roof beams B and B1 and on the center line of the joint beams S4 and S5. Bolt to.

[Action]

On each roofline of the roof structure, the plate-shaped attachment pieces provided at the lower end of the vertical members on the eaves side and the ridge side are installed on the upper surface of the roof beam and on the centerline of the horizontal joint beam that is installed at a right angle between the roof beams. Bolt in position. Since the mounting piece is thus fixed to a portion of the roof beam that is reinforced by the joint beam and has high strength, the joint member can improve the mounting strength of the eave-side and ridge-side vertical members.

[Effect of device]

As described above, the structure for mounting the roof structure of the present invention is such that the roof is provided on the upper surface of the parallel roof beams extending in the direction of the roof and at the position on the center line of the two joint beams that are erected at right angles between the roof beams. The roof structure is attached to the roof beam by bolting the two vertical members on the eaves side of the upper structure and the mounting pieces provided at the lower ends of the vertical members on the ridge side. The vertical beam on the ridge side can be supported by the roof beam at the position where the strength is increased by the connecting beam, and the mounting strength of the rooftop structure can be improved. Therefore, even when an external force such as a large wind pressure due to a strong wind acts on the roof structure, this external force can be dispersed through the roof beam and the joint beam, and damage and deformation of the roof structure can be prevented.

Further, since the panel mounting piece for mounting the panel forming the wall of the roof structure is formed in the joint material of the roof structure, the work of mounting the panel can be made efficient and the workability can be improved.
