Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ridge device for a flat plate type roof that can prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridge portion of the flat plate type roof.

[Conventional technology and its problems]

Conventionally, ridge devices for roofs with tile stick roofs have generally been installed with a ridge wrapping material of an appropriate length in the longitudinal direction, and the ridge wrapping material has been attached to be able to expand and contract. Thermal expansion and contraction caused the ridge wrapping material to undergo metal fatigue, resulting in serious defects such as cracks appearing in the middle, resulting in breakage and rainwater infiltration.

[Means to solve the problem]

Therefore, as a result of intensive research in order to solve the above-mentioned problem, the inventor has developed the invention by forming the ridge part of a flat plate type roof with a tie-fastening part as an opening, and A rising part is formed at the upper end of the flat main plate on the water side of the roof board, and the notch on both sides of the door is connected to the fastening part between the fastening parts in the direction in which the roof boards are installed at the ridge part. This is a flat plate type roof in which the mento is slidably arranged in the longitudinal direction of the roof board, the ridge covering board is placed so as to cover the mento on both sides of the ridge, and the ridge covering board is fixed to the mento. By using a ridge device for a fastened roof, it is possible to prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridge part of a flat plate type fastened roof, and the ridge part can be well protected from rain, thus solving the above problems. It is.

〔Effect of the invention〕

In the present invention, the ridge part of the flat plate type fastening roofs A, A having the fastening part _A1 is formed as the opening part 6, and the water side of the flat main plate 1a of the roof plate 1 at the ridge part. A rising part 7 is formed at the upper end, and a tightening part A ₁ , A ₁ in the direction in which the roof sheets 1 are installed at the ridge part
In between, the notches 9d, 9d on both sides of the door 9 are engaged with the locking parts _A1 , _A1 , and the door 9 is arranged so as to be slidable in the longitudinal direction of the roof board 1, Place the ridge cover plate 10 so as to cover the side doors 9, 9 of the ridge cover plate 10.
By fixing it to the door 9, firstly, it is possible to prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridges of the flat plate type roofs A, A, and secondly, the ridges can be well protected from rain. Thirdly, it has advantages such as ease of construction and cost reduction.

To explain the operation and effect in detail, first, the roof sheets 1 constituting the flat plate type roof A, expand and contract appropriately in the longitudinal direction according to the outside temperature, and the flat plate type roofs A,A Even if expansion/contraction appears in the ridge part, the existence of the opening 6 and the fact that both sides of the ridge cover board 10 covering the opening 6 are fixed to the side doors 9, 9, The ridge cover board 10 is attached to the roof via a door 9, and the door panels 9, 9 are arranged appropriately in the longitudinal direction of the roof board 1, so that the ridge cover board 10 and the flat plate type No thermal stress is generated in the roof sheets 1 constituting the fastened roof A, and the occurrence of thermal strain can be reliably prevented. In addition, the plate ringing phenomenon caused by thermal expansion and contraction can also be prevented.

In addition, in such a configuration, the notch 9 of the door 9 can withstand a load in a direction perpendicular to the ridge cover plate 10.
d is locked to the locking part _A1 and can be held with sufficient strength.

Furthermore, although it is possible to prevent the occurrence of thermal distortion in the ridge cover plate 10 and the roof plate 1 constituting the flat plate type roof A, the presence of the rising portion 7 of the side door 9 causes damage to the interior. It is possible to provide a ridge device for a flat plate type roof that can reliably block the infiltration of rainwater and has excellent rain closure (watertightness).

Moreover, the structure of the ridge device is relatively simple, and the construction can be carried out easily and quickly without any danger by working from the roof, which in turn can reduce the construction cost.

In addition, if both ends of the vertical part 9a of the door 9 are formed as inclined edges 9e, 9e with elasticity, even if rainwater is sprayed strongly from below on the water side of the ridge part, the edge will have elasticity. The inclined edges 9e and 9e are the tightening parts.
Since the sides of A ₁ are spring-backed by the so-called springback phenomenon within the elastic limit, the spring-backed inclined edges 9e, 9e can be formed into a dam-like shape to block rainwater intrusion, and the springback can easily be caused by the springback. It can be installed so that it does not come off.
