[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a ventilation structure in a ridge portion of a horizontally-roofed roof which uses a metal shingle in a horizontal direction and is laid one on top of another. The present invention relates to a ventilation structure of a ridge when a ridge support space is formed by forming a ridge support space, which is opened to the outside, and communicates with a ventilation port provided at the top of the attic.

[0002]

2. Description of the Related Art In a building having a normal flowing roof, a main building is erected in a hut group, and in the case of a concrete structural body, a roof is provided at predetermined intervals on the upper surface thereof to cover the entire roof surface. Lay a field board and lay roof tiles or its equivalent on top of it. Many roofs that have a metal roofing panel as the roofing material have a metal structure in the upper part of the main building or roof. A horizontal roofing is performed using a bar. And, in the fitting structure in the upper part of the ridge of such a roof structure, it is formed from the roof surface to form a rooftop,
This part fits in from both sides of the roof and the rain, and it is well-completed. Ventilation is required mainly for hot air stagnating in the attic, and natural ventilation is provided.

[0003]

[Problem to be Solved by the Invention] One of the drawbacks of the conventional structure of a metal plate horizontal roof is that the overall structure is a light structure, so that the structure of the roof overtops becomes a heavy upper structure. In addition, materials suitable for a ventilation structure of a ridge portion corresponding to a basic design of a house or the like are not provided even as a natural ventilation structure. In the conventional ridge-mounting structure, a ridge member support device is installed in the ridge to form a ridge support space, and this space is opened to the outside so that it can communicate with the ventilation openings provided on the top of the roof surface. By doing so, the ridge is ventilated. However, it is necessary to secure the communication between the ventilation port formed at the top of the roof surface and the ridge support space formed by the ridge support member, and to secure the upper edge of the roof member and the top of the ridge top where the ventilation structure is formed. The most disadvantageous point in the overall structure with the rain-fighting structure is that the members on both sides of the ventilation port are separately formed.

[0004] Therefore, as in the invention of the "ridge ventilation device" disclosed in Japanese Utility Model Publication No. 58-9716, the members on both sides of the ventilation opening are integrally formed to form a ridge support structure. In this invention, a gas-liquid separation chamber is formed between the uppermost ridge member called "top" and the ridge-supporting structure, and the ridge member and the ridge-supporting structure are fitted. Not only does it require a seal material, but also because each member is molded over the entire length in the ridge direction, it is necessary to provide communication between the space formed by the ridge support and the outside. Therefore, it is necessary to form a large number of ventilation holes and exhaust holes, which requires a lot of work as a ventilation structure for the ridge.

[0005]

SUMMARY OF THE INVENTION In view of the above problems, the present invention seeks to improve the structure of a horizontal roof that uses a metal roof slab in a horizontal direction and that is laid on top of one another. It was created with the aim of providing a structure that allows for simple natural ventilation. Drop it down to form a roof surface, form a ridge at the top of the roof surface, install a ridge member support device in this part, and connect the ridge support space formed by the support device to the outside and the ventilation opening on the attic. In the ventilation structure of the ridge part which is made to communicate, the support device for supporting the ridge member is fixed to each opposed portion on the upper surface of the barbed on both sides of the ridge, and the ridge support member formed by folding up the central part. The ridge support member is formed by folding up the outside of the fixed part to the slack on both sides of the ridge support member. An opening support member placed and fixed on the face door support portion, and a connecting member connecting the tops of the ridge support member and the opening support member, and the ridge wrapping plate is covered over such a connecting member. It is characterized by the following.

[0006]

[Operation] Therefore, according to the present invention, a ventilation structure of a ridge portion is easily formed on a roof in which a shingle is laid sideways by using a metal shingle sideways, and a supporting device for supporting a ridge member is provided. This device is only fixed to the opposing parts of the upper surface of the rafters on both sides of the ridge, and this device is used for the ridge support member formed by folding up the central part, and for the slack on both sides of the ridge support member. Three types of processing: an opening support member placed and fixed on a face door support portion formed by folding up the outside of the fixing portion, and a connecting member connecting the tops of the ridge support member and the opening support member. It is composed only of members. Therefore, assembling the above members, covering them in the longitudinal direction with the wrapping plate of the ridge, and raising the upper edge of the shingle, the ventilation structure of the ridge is formed. A ventilation hole is formed at the edge, and the ventilation is performed over the entire opening between the opening support members. In addition, when the double insulation method is adopted for the specifications of the ground board, an intermediate air layer is communicated with the ridge support space, so that the degree of freedom in changing to a snowy area or the like is large.
