Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure with a rain gutter. Specifically, a plurality of roof panels installed adjacent to each other on the upper part of the building body and each having an independent inner gutter on the eaves side, and a common roof girth that is placed across the plurality of roof panels to connect the inner gutters And a roof structure with a gutter having a collecting pipe of

[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 hanging each gutter receiving bracket, a roof is formed on the roof side rafters, and an eave roof is formed on the eaves side rafters,
A rain gutter having an open upper surface over the entire length in the longitudinal direction is housed between the roofs, and the gutter is fixed to each gutter bracket.

[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 U-shaped gutter brackets have to be hung between the rafters and the rafters, the structure for installing the rain gutter is extremely complicated and labor-intensive. 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, in the case of such a structure, at the construction site, after installing a plurality of roof panels on the upper part of the building body, it is necessary to install a common collecting pipe across these roof panels. However, when installing the gathering pipe, if it takes labor and time to attach the member that supports the gathering pipe to the building body or roof panel, the effect of the roof construction method will be reduced by half, so it will be easy. A structure that can be easily supported is desired.

The object of the present invention is to solve all of the above-mentioned drawbacks of the prior art, to easily construct a roof panel having an inner gutter, and to connect an inner gutter of adjacent roof panels. It is intended to provide a roof structure with a rain gutter having a structure capable of easily supporting a pipe.
