Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal roof construction structure.

[0002]

2. Description of the Related Art As a conventional construction structure of a metal roof, there is one shown in FIGS. 4 and 5, for example.

In the structure shown in FIG. 4, the tight frame 13
The base end portion of the suspension 12 having a Z-shaped cross section is fixed to the stepped portion with a bolt, and the end portion of the metal roof plate 11 on one side 11b is connected to the top of the suspension member 12, and then the metal roof plate 11 The other side 1
The end of 1a is crimped to the connection.

Further, in the structure shown in FIG. 5, a suspension 22 having an arcuate locking portion formed on one side of the top is fixed between the tight frames 23, 23, and then one side 2 of the metal roof plate 21.
After the end portion of 1b is engaged with the inside of the arcuate locking portion of the hanger, the end portion of the other side 21a of the metal roof plate 21 is crimp-connected to the engaging portion.

[0005]

However, in the structure shown in FIG. 4, the end of one side 11b of the metal roof plate 11 is attached to the hanger 12.
It is connected to the top of the and the construction is troublesome.

The other end 11a of the metal roof plate 11 is integrally fastened together with the top of the suspension 12 and the one side 11b of the metal roof plate 11 so that the other side of the metal roof plate 11 is secured. 11a has a weak seam tightening strength, and therefore a weak wind pressure strength (a strength to withstand the blowing force), and an accident occurs in which it scatters in a strong wind. Moreover, in the one shown in FIG.
The end portion of the one side 21b of No. 1 is engaged with the inside of the arcuate locking portion of the hanger, which makes the construction troublesome.

The 21a side of the metal roof plate 21 is integrated with the hanger 22 by the bent portion 22a of the hanger 22 to maintain wind pressure resistance, but the 21b side of the metal roof plate 21 is
Insufficient transmission of the force to the suspension 22 causes the same problem as described above. In this case, if it is forcibly tightened to increase the wind pressure resistance, the surface coating of the metal roof plate 21 will be damaged. An object of the present invention is to provide a metal roof construction structure capable of solving the above problems.

[0008]

The structure for constructing a metal roof according to the present invention comprises a tight frame having suspension fixing portions at both ends and a suspension fixed by the fixing portions at both ends of the tight frame. A roof plate locking part with an arc-shaped cross section is formed to project, and a metal roof plate molded into a cross-sectional shape that matches the cross-sectional shape of the tight frame and the arc-shaped locking part of the suspension, at both ends. And a connection part for crimping and connecting the adjacent metal roof plates to each other.

[0009]

[Operation] A roof plate locking portion having an arcuate cross section is formed to project from both sides of the top of the hanger, and the locking bent portion projects from the hanger body to the locking bent portion. By integrally locking the metal roof plate formed in a suitable cross-sectional shape, the wind pressure resistance can be significantly improved. Further, the cross section of the locking portion of the metal roof plate of the suspension has an arc shape, and the metal roof plate can be locked easily by pushing it in from above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall configuration diagram showing an embodiment of the present invention and a perspective view of a hanger, and FIG. 2 is an explanatory diagram showing a construction procedure.

In FIG. 1, a tight frame 3 is welded to a structural member (beam, sub-beam, etc.) 4 of a building, and a suspension 2 is set by bolts 7 between both ends fixing portions 3 a of the tight frame 3. ing.

The tight frame 3 has a medium plate thickness (3.
A steel plate of about 2 to 6.0 mm) is formed in a deck plate shape in cross section with fixing parts 3a of the suspension at both ends thereof, and its width is about 20 to 50 mm.

The hanger 2 is made of a steel plate having a plate thickness of about 3.2 to 6.0 mm and a width of about 30 to 100 mm, a slit is formed in the upper part thereof, and the roof plate engaging portions 2a having arcuate cross sections on both sides.
However, it is formed so as to have a bent corner portion 2b between itself and the main body portion, and has a bolt hole 7a.

On the other hand, the metal roof plate 1 as a roofing material is
Shoulder parts 6a, 6b which are made of a metal thin plate (color iron plate, damping steel plate, stainless steel plate, etc.) are fitted to the cross-sectional shape of the tight frame 3 and engage with the corners 2b and the arcuate locking portions 2a of the suspension. And arc-shaped locking portions 5a and 5b, and crimp portions 5c and 5d at both ends, which are molded (usually cold roll forming).

Then, as shown in FIG. 2, the shoulder portion 6b and the arcuate locking portion 5b on one side of the metal roof plate 1 shown by the solid line are locked to the corner portions 2b and the locking portion 2a of the suspension. , The shoulder portion 6a on the other side is temporarily placed on the hanger 2.

Next, by pushing down the shoulder portion 6a on the other side from above, the locking portion 2a of the suspension 2 is formed in an arc shape, and due to the spring action of the metal roof plate 1, it is indicated by a broken line. Thus, the shoulder portion 6a on the other side of the metal roof plate 1 is easily locked to the corner portion 2b of the suspension.

Thus, the shoulder portion 6 of the metal roof plate 1
Since the a and 6b are integrally locked to the bent corner portion 2a of the suspension 2, the wind pressure resistance can be significantly improved.

Then, as shown in FIG. 2b, the seam connection portions 5c and 5d at both ends of the metal roof plate 1 are engaged with each other,
Finally, the mating part is compressed and crushed to connect. In this case, the crimp connection is made only by the two metal roof plates 1, so that the adhesion is improved and the water blocking property is improved. Also,
Unnecessary forceful tightening work is unnecessary and deterioration of the painted surface can be prevented. Next, a modified example of the suspension is shown in FIG. 3a.

In this case, the suspension 8 has two slits at its upper portion, and both ends thereof have roof plate engaging portions 8a having arcuate cross-sections on both sides, as in the case of the suspension 2 described above. It is formed so as to have a bent corner portion 8b between itself and the main body portion.
The roof plate locking portion 8c having an arcuate cross section is provided at the upper end of the central portion.
Are formed. Construction of the metal roof board 1 in this case,
The same is done as in FIG. 2a above.

However, as shown in FIG. 3b, an arcuate locking portion 5f which is locked to the locking portions 8a and 8c of the suspension is formed at one end of the metal roof plate 1 and the other side thereof is formed. A locking portion 5e that is locked to the locking portions 8a, 8c, 8a of the suspension is formed at the end portion. Finally, the locking portion 5e is wound around the locking portion 5f and is tightened.

[0021]

EFFECT OF THE INVENTION The construction structure of the metal roof of the present invention is as described above, and it is possible to greatly improve the wind pressure resistance and to improve the workability and waterproofness of the seam tightening portion. It is possible to prevent deterioration of surface coating.
