Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof member that constitutes a roof such as a roof panel or a roof unit. For more information,
The present invention relates to a roof member that incorporates an inner gutter on the eaves side.

[0002]

[Background Art] As a rain gutter installed on a roof of a building, in addition to a so-called outer gutter provided along the eaves tip edge of the roof, a rain gutter located slightly above the eaves side edge of the roof. The so-called inner gutter that houses the so-called "gutter" is known. The inner gutter has a good appearance because the rain gutter cannot be seen from the outside (front).
It is often used in the roofs of modern high-class buildings.

Conventionally, as the structure of the inner gutter, for example, the structure described in Japanese Utility Model Laid-Open No. 58-11527 is known. This is to divide multiple rafters that are installed to incline from the ridge toward the eaves into the ridge side and the eaves side, and for each rafter, a U-shape between the rafters on the ridge side and the eaves side. Along with each of the gutter brackets, a roof was formed on the rafters on the ridge side, and a roof was formed on the rafters on the eaves side. The gutters are stored and the rain gutters are fixed to the gutter brackets.

[0004]

However, in the conventional structure of the inner gutter, at the construction site, a plurality of rafters are divided into a ridge side and an eaves side, and each rafter has a rafter on the ridge side and an eaves side. Since the U-shaped gutter brackets must be hung between the rafters and the rafters, the structure for installing the rain gutter is extremely complicated and time-consuming, and the connection between adjacent rain gutters and each roof There is a drawback in that it also takes time and effort to carry out waterproofing at the connection part with. Moreover, since these operations must be performed at a high place, there are drawbacks such as danger and poor work efficiency.

Therefore, in order to solve such a drawback, the present applicant manufactured a roof panel in which an independent inner gutter is incorporated on the eaves side of the roof panel body in a factory,
At the construction site, after installing a plurality of roof panels adjacent to each other on the upper part of the building main body with a predetermined slope, connect the inner gutters of each roof panel main body with a common collecting pipe, and from each inner gutter through this collecting pipe. We are proposing a roof construction method that collects and discharges the rainwater.

According to this construction method, the roof panel in which an independent inner gutter is incorporated on the eaves side of the roof panel main body is manufactured in advance in the factory. Since the inner gutter can be installed simply by installing multiple roof panels, the work of installing the rain gutter on-site can be eliminated. Moreover, since the inner gutters are independent for each roof panel body, and the rainwater from these inner gutters is collected and discharged through a common collecting pipe, there is no need to connect the inner gutters, and waterproof treatment is simple. You can expect the effect that you can.

However, when manufacturing a roof panel incorporating an independent inner gutter on the eaves side of the roof panel body in a factory, a plurality of rafters are divided into a ridge side and an eaves side as in the conventional case. With a structure in which a U-shaped gutter bracket is hung on each rafter and a rain gutter is stored and fixed there, the manufacturing process is complicated and labor-intensive, so there is still the drawback that cost reduction cannot be expected.

It is an object of the present invention to provide a roof member with an inner gutter which eliminates all of the above-mentioned conventional drawbacks and allows a roof member having an inner gutter to be easily constructed.

[0009]

Therefore, in the roof member with an inner gutter of the present invention, the roof frame including a pair of both side frames arranged at a predetermined interval and the eaves portion between the both side frames of the roof frame are excluded. A roof material provided on the surface, an eaves side frame hung over the eaves side end between the both side frames, and an inner gutter housed between the eaves side frame and the lower end of the roof material. It is characterized by having.

[0010]

When manufacturing the roof member, the roof frame is formed by including a pair of both side frames, the roof material is provided on the surface of the roof frame excluding the eaves portion between the both side frames, and the eaves side end between the both frames is formed. By straddling the eaves side frame to the part, if the inner gutter is housed and arranged between the lower end of the roofing material and the eaves side frame, a roof member with an inner gutter can be constructed, so compared to the conventional structure, The roof member having the inner gutter can be easily configured.
