Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a ventilation opening device for a horizontal roof structure, and more particularly, in a horizontal roof structure of a building, a vent device is installed on the roof surface inside the roof frame. This invention relates to a ventilation opening device in a horizontal roof structure in which a communicating ventilation tube is projected and the ventilation tube portion is covered from the outside by a decorative dormer-like structure.

[Prior Art] In a building structure having a normal horizontal roof structure,
In order to ventilate the inside of the roof structure and each room as needed, in the past, so-called ventilation lines were configured to protrude from the ridge of the horizontal roof structure. Generally, all the ventilation of the required parts is performed centrally through this ventilation line.

In addition, in response to the diversification of external designs and functional requirements for architectural structures with horizontal roof structures, for example, it is no longer necessary to have a ridge that should have a protruding ventilation ridge. There are often cases where it is necessary to locally ventilate only one specific room within a structure, such as a horizontally-roofed structure. For each required part, ventilation pipes were made to protrude like chimneys, or dormer-shaped ventilation ridges were installed.

[Problems to be Solved by the Invention] However, in the case of the ventilation port device for the conventional horizontal roof structure configured as described above, the means of protruding the ventilation tube in the shape of a chimney on the roof surface has a problem in its external design. This has the disadvantage that it does not necessarily match the overall design of the building, and the method of installing a dormer-shaped ventilation ridge on the roof surface has the disadvantage that it does not necessarily match the overall design of the building.
The installation of a dormer-shaped ventilation ridge that covers this ventilation opening from the outside is structurally related, for example, the roof structure of the horizontal roof structure,
Alternatively, it may be necessary to construct a special framework in advance for attaching this dormer-shaped ventilation ridge to the building frame, and such an installation may complicate the structure, which may cause problems in buildings with a horizontal roof structure. This leads to a prolongation of the construction period for the structure, resulting in various problems in terms of construction costs, etc.

This invention is an attempt to improve such conventional problems, and its purpose is to improve the horizontal roof structure using horizontal roof plate members made of long metal thin steel plates. Along with protruding a ventilation tube at a predetermined position,
The dormer-like structure including this ventilation pipe part can be easily installed. The object of the present invention is to provide a ventilation opening device for this type of horizontal roof structure.

[Means to solve the problem]

In order to achieve the above object, the ventilation opening device for a horizontal roof structure according to the present invention not only raises the horizontal roof using horizontal roof plate members, but also provides a ventilation pipe that communicates with the inside of the roof frame at a predetermined position. In the case of protruding parts, metal fittings should be attached to predetermined positions between the mutually securing parts of the upper and lower horizontal roof sheet members within the range encompassing the ventilation pipe, and each of these installations should be A dormer-like structure pre-assembled in a factory is attached to the metal fittings.

That is, the present invention uses a plurality of horizontal roofing board members, and engages and fastens adjacent engaging portions of each horizontal roofing board member disposed on a roof frame to achieve a desired result. In the horizontal roof structure, the roof surface of the street is thatched, and a ventilation pipe that communicates with the inside of the roof structure projects from the roof surface.
Attachment fittings are respectively protruded from a predetermined position within the range encompassing the ventilation tube between the engaging parts of each of the horizontal roofing plate members, and each of these attachment fittings is arranged protruding from the respective fittings on the face plate part. On the other hand, there is provided a ventilation opening device for a horizontal roof structure, characterized in that a dormer-like structure is attached to cover the ventilation pipe from the outside and provide a ventilation opening portion that communicates with the outside.

[Function 1] Therefore, in this invention, in addition to raising the horizontal roof by each horizontal roof plate member, the ventilation pipe is enclosed in a structure in which the ventilation pipe communicating with the inside of the roof frame is protruded from a predetermined position. For installation, metal fittings are attached to predetermined positions between the mutually engaging parts of the upper and lower horizontal roofing sheet members within the range, and each of these installations is performed using factory-produced metal fittings. In order to attach the dormer-like structure that was assembled by the following method, in order to cover the ventilation pipe and attach the dormer-like structure, add this dormer-like structure to the roof frame of the horizontal roof structure in advance. There is no need to construct a dedicated frame or the like, and a dormer-like structure can be installed extremely easily to cover the ventilation tube on the horizontal roof surface, making it easy to configure this type of ventilation opening device. It is possible.
