Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing roof plate made of a metal steel plate which is roofed on a base member such as a purlin of a building, and a construction structure for a roofing roof using the roof plate.

[0002]

2. Description of the Related Art Conventionally, in this kind of thatched roof,
For example, Japanese Utility Model Publication No. 52-7692 or Japanese Utility Model Publication No. 52
Some have a configuration such as disclosed in Japanese Patent Publication No. 7693.

Such a horizontal roof having such a conventional structure has an inverted U-shaped bent portion formed at an eave-side engaging portion of a horizontal thatched roof plate laid on a base member such as a purlin or the like, and is directed toward the eaves. The upright piece formed on the ridge-side engaging portion of the other side-roofing roof plate adjacent to the above can be fitted and joined.

[0004]

However, in the above-mentioned conventional side-roof roof structure, the capillarity phenomenon is apt to occur at the joint portion of the side-roof roof plates during a storm, and the air-tight fit is achieved. Because it is impossible to do so, rainwater may enter inside.

Further, in the conventional thatched roof, as shown in FIG.
As shown in, while engaging the eaves side engaging part c of the other side thatched roof plate a with the ridge side engagement part b of the one sided thatched roof plate a adjacent to each other in the eaves direction, Sided roofing board a
There is one having a structure in which a joint portion is a high seam joint made of a thin metal steel plate.

[0006] In such a side-roof roof structure, especially in a snowy cold region, if the snowmelt water is re-frozen and the ice blocks adhere to the joints between the side-roof roof plates, as shown in FIG. Load F due to the weight of each of the engaging parts b, c
As shown by the solid line arrow in Fig. 11, the rising part of is deformed by extending from the ridge side to the eaves side, and the engagement of the goby becomes loose, which not only lowers the wind pressure resistance and the rain performance. However, as shown in FIG. 12, when the wind pressure W in the ridge side direction is received, there is a problem that the side-roofing roofing plate a is likely to come off.

[0007]

OBJECT OF THE INVENTION An object of the present invention is to prevent a deformation of a joint portion of a horizontal thatched roof plate due to a load, and to improve wind pressure resistance and rain warding performance, and a thatched roof plate and the thatched roof. It is to provide a construction structure of a thatched roof using planks.

[0008]

In order to solve the above-mentioned problems, the present invention is laid on a base member such as a purlin,
And in the lateral thatched roof plate provided with the eaves side engaging portion and the ridge side engaging portion at both end portions in the eaves ridge direction, the ridge side engaging portion,
An inner rising portion and an outer rising portion that is formed on the outer side of the inner rising portion via a decompression space groove and has a support portion facing the decompression space groove, and the eaves side engaging portion is An engagement groove which is formed by bending the inside in an inverted U shape and engages with the inner rising portion of the ridge-side engagement portion and whose inner wall portion faces the decompression space groove. It is characterized in that the inner wall portion of the joint groove is folded back to the upper side of the ridge and has a locking portion that can be elastically locked to the support portion.

Further, according to the present invention, when laying and constructing the side-roofing roofing plates having the above-mentioned structure adjacent to each other in the direction of the eaves on a base member such as a purlin, the above-mentioned adjacent side-roofing roofing plates The engaging groove of the eaves side engaging portion of the upper roofing roofing plate is engaged with the inner rising portion of the ridge side engaging portion, and the locking portion formed by folding back on the inner wall portion of the engaging groove is provided in the lower stage. A construction structure for a thatched roof is characterized in that it is elastically locked to a support portion formed on an outer rising portion of an ridge-side engagement portion of the thatched roof plate.

[0010]

That is, according to the present invention, the ridge-side engaging portion of the thatched roof plate is formed on the inner rising portion and on the outer side of the inner rising portion via the depressurization space groove, and faces the depressurization space groove. Formed with the outer rising part with a support part,
The eaves side engaging portion is formed by an engaging groove formed of both inner and outer wall portions that are bent inward in an inverted U shape and engages with the inner rising portion of the ridge side engaging portion, and The inner wall portion of the engaging groove facing the inside of the decompression space groove is folded back to the ridge side to be a locking portion, while the inner rising portion of the ridge-side engaging portion of the adjacent lower side thatched roof plates has an upper portion. Engage the engaging groove of the eaves side engaging part of the horizontal thatched roof plate, and the locking part formed by folding back on the inner wall part of this engaging groove rises outside the ridge side engaging part of the lower thatched roofing plate. By engaging elastically with the support part formed in the upper part, the inner rising part of the ridge-side engaging part of the lower horizontal thatched roof plate and the engaging groove of the eaves-side engaging part of the upper horizontal thatched roof plate By the engagement with the, the snowmelt water is re-frozen and the ice blocks adhere to the joints between the roofing roof boards. As in the above, the eaves side engaging part of the side thatched roof plate is not deformed by being pulled in the eaves side direction, so the goby is firmly meshed, which reduces wind pressure resistance and rain performance. Is prevented.

Further, since the ridge-side engaging portion of the lateral thatched roof plate is formed with an inner rising portion which is engaged with the engaging groove formed in the eaves side engaging portion of the upper lateral thatched roof plate, Rainwater does not infiltrate into the inside of the back side of the roofing roofing board, and rainwater infiltrates into the decompression space groove between the inner rising part and the outer rising part from the gap with the engaging groove even during storms. Even
When rainwater passes through the gap, the kinetic energy of the rainwater attenuated while passing through the gap, further, with a pressure is weakened in the vacuum space within the groove, rainwater in this vacuum space groove is transiently water retention, Drainage is carried out in a direction orthogonal to the eaves side of the side thatched roof plate, and rainwater is reliably prevented from entering the inside of the back side of the side thatched roof plate.
