Description

[Detailed description of the invention] Industrial application field This invention relates to a waterproofing device for a solar heat collection roof.

In this specification, the term "solar heat collecting roof" refers to a roof at least partially composed of a solar heat collector, and includes the rafters.

Conventional technology Conventionally, on roofs equipped with integrated solar heat collectors, waterproofing is applied to the entire back side of the collector to prevent rainwater and condensation water from entering, but this is extremely difficult to do. However, there were problems in that the cost was high and the construction period was long.

Conventionally, a frame body is fixed on the roof board to form a box-shaped body, a solar heat collection mechanism is installed inside the box-shaped body, a transparent plate is attached to the top surface of the box-shaped body, and A solar heat collection unit is already known in which downpipes are provided on both the left and right sides of the frame body, and horizontal gutters that communicate with the downpipes are provided on both the front and rear sides of the frame body (see, for example, Japanese Patent Application Laid-Open No. 153854/1983). .

However, according to this conventional solar heat collection unit, the roofing board constitutes a part of the heat collection unit, so when multiple solar heat collection mechanisms are installed, the unit becomes large and handling is extremely troublesome. It was hot. Furthermore, since the heat collecting unit is provided protruding from the upper side of the rafters, the roof becomes bulky as a whole, resulting in an unsightly appearance. Furthermore, since the vertical gutter and horizontal gutter are integrated with the frame of the solar heat collector, the shape of the extruded material that makes up the frame becomes complicated, which makes manufacturing the frame cumbersome and costly. was expensive. Furthermore, conventionally, there has been a problem in that rainwater that has entered the inside of the box-like body and dew water that has formed inside the box-like body cannot be discharged to the outside.

Purpose of the invention The purpose of this invention is to solve the above problems and to quickly drain rainwater and condensation water without applying waterproofing to the back side of the solar heat collector as in the past. Therefore, the cost is low and the construction period can be shortened.In addition, the solar heat collector can be installed individually at the desired location on the roof, making the installation work easy. By installing the solar heat collector in a depressed manner, the roof does not become bulky and looks good, and the extruded material that makes up the side frame of the solar heat collector has a simple shape and is easy to manufacture. Furthermore, the manufacturing cost of the solar heat collecting roof can be reduced, and the solar heat collecting roof can quickly discharge rainwater that has entered the solar heat collector and dew water that has formed inside the solar heat collector to the outside. We are trying to provide waterproof equipment.

Structure of the invention In order to achieve the above-mentioned purpose, this invention provides an outwardly projecting wall at the upper part of the side frame of the solar heat collector.
