Description

DETAILED DESCRIPTION OF THE INVENTION 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.

Conventionally, ridge devices for roofs with tile stick roofs were generally installed with a ridge wrapping material of an appropriate length in the longitudinal direction, and the ridge wrapping material was 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.

Therefore, the present invention forms the ridge part of a flat plate type roof as an opening, forms a rising part at the water-side upper end of the flat main plate of the construction board facing the ridge part, and Slideably lock the slide fittings on the locking parts on the water side facing each other, place the ridge cover plate so as to cover both the left and right slide fittings, and fix the ridge cover plate to the slide metal fittings. By providing side door plates on both sides of the ridge cover plate, 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 roof, and to improve the rain protection of the ridge part. This eliminates the drawbacks of

The structure will be explained with reference to the drawings.

In the case of A ₁ , it is formed as shown in Fig. 15,
In the case of the locking part _A1 consisting of the upper rib part 1b and the lower rib part 1c, it is formed as shown in FIGS. 8, 11, and 12. Slide fitting 9 of second embodiment
Notches 9d, 9d, which are approximately similar in shape to the locking part _A1 , are provided on both sides of the gate-shaped part 9c (Fig. 3, Fig. 10, Fig. 13, Fig. 14, etc.). reference). Reference numeral 10 is a long metal ridge cover plate or a ridge cover plate of an appropriate length, and has gently sloped portions 10a, 10a formed symmetrically and formed into a chevron-shaped portion having a substantially V-shaped cross section. Reference numeral 11 denotes a door plate, which is integrally formed on both sides (bottom end on the water side) of the gently sloped parts 10a, 10a of the ridge cover plate 10 (see Figs. 1, 2, and 7);
Alternatively, the door panel 11 may be a separate member from the ridge panel 10, and may be slidably provided on folded edges provided from both ends of the ridge panel 10. As shown in Fig. 1, the door plate 11 is provided except for _one part of the locking part A.

The slide fittings 9 are inserted and locked into the opposing locking portions A ₁ and A ₁ at the ridge portion. In the embodiment, the slide fitting 9 is simply attached to the fastening part _{A1 .}
It is inserted from the ridge part side. The slide fitting 9 inserted and locked in this manner is attached so that it can appropriately slide in the longitudinal direction of the locking portion _A1 , but cannot be moved in the vertical direction. The ridge cover plate 10 is placed so as to cover both the left and right slide fittings 9, 9 at the ridge portion, and both side portions of the ridge cover plate 10 are fixed to the left and right slide fittings 9, 9. In the example,
The gently sloped parts 10a, 10a of the ridge covering board 10 are covered with both the left and right slide fittings 9, 9 of the ridge part and the ridge part of the flat roof A, and the gently sloped parts 10a and the slide fittings 9 The upper surface of the gate-shaped part 9a or the gate-shaped part 9c is fixed with rivets or the like. The fixing is to fix the slide fitting 9 and the ridge cover plate 10 as shown in FIGS. 17 to 21, and it is necessary that the slide fitting 9 and the fastening part _A1 are not fixed.

Note that, as shown in FIGS. 3, 4, 8, and 9, bent edges 9e may be formed at the front and rear ends of the holding portion 9b of the slide fitting 9 or at the periphery of the notch 9d. This is to make insertion easier and to prevent damage such as scratches to the fastening part _A1 after insertion.

Next, the effects will be explained.

In the present invention, a flat plate type fastened roof A,
The ridge part 6 of A is formed as an opening, and the flat main plate 1 of the architectural boards 1, 1 facing the ridge part
A rising part 7, 7 is formed at the upper end of the above water side of a, 1a, and a ridge fastening part on the above water side where the ridge part is opposite
The slide fittings 9, 9 are slidably locked on A ₁ , A ₁ , and the ridge cover plate 10 is placed so as to cover both the left and right slide fittings 9 , 9 , and the ridge cover plate 10 is attached to the slide metal fittings 9 . By fixing it to the ridge and providing the side door plates 11, 11 on both sides of the ridge cover plate 10, firstly, it is possible to prevent the occurrence of thermal distortion due to thermal expansion and contraction at the ridge portion of the flat plate type ridge roof A, A. Second, the ridge portion can be well protected from rain, and third, it can be constructed at low cost.

To explain the operation and effect in detail, first, the construction board 1 constituting the flat plate type roof A is thermally expanded and contracted in the longitudinal direction according to the outside temperature, and the flat plate type roof A, Even if expansion/contraction appears in the ridge part of A, it is due to the existence of the opening 6 and the fact that both sides of the ridge cover plate 10 covering the opening 6 are fixed to the slide fittings 9, 9. , its ridge cover plate 1
0 is a configuration in which the slide fittings 9 are attached to the roof via the sliding fittings 9, and the sliding fittings 9, 9 are attached to the fastening parts A ₁ ,
_A1 so that it slides appropriately in the longitudinal direction,
No thermal stress is generated in the ridge covering board 10 and the building board 1 constituting the flat plate type 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 particular, the slide fitting 9 has a simple structure and can be locked easily and quickly without using fasteners such as bolts, and has the great advantage of being able to slide. Tetsuteso ridge plate 10
It has sufficient strength to withstand loads in the vertical direction.

Furthermore, although it is possible to prevent the occurrence of thermal distortion in the ridge cover board 10 and the construction board 1 constituting the flat roof type roof A, the presence of the face door board 11 and the rising portion 7 It can reliably block rainwater from entering the interior, making it rainproof (watertight).
We can provide an excellent ridge device for flat plate type roofs.

Further, 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.
