DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension for attaching a roof slab made of a steel plate or the like to a roof base and fixing the same to a roof slab having a heat insulating performance.

[0002]

2. Description of the Related Art Conventionally, when forming a roof having heat insulating performance, a heat insulating material formed of polyurethane foam, styrofoam, rock wool, glass wool, or the like is interposed on a base of a roof such as a field board or the like, and is formed of a steel plate or the like. Roofing materials are being laid. As a method of laying a roof sheet with a heat insulating material interposed on the roof base, the heat insulating material is laid on the roof base, and then the roof sheet is placed on the heat insulating material, or the heat insulating material is placed on the roof sheet. There is a method of mounting a backed roof panel on a roof base. In attaching and fixing the roof slab to the roof foundation, a suspension is used.

FIG. 7 shows an example of the construction of the roof slab 2 when the roof panel 10 is used. Engagement part 3 which protrudes upward by bending at the ridge side end of roof shingle 2
Are formed at the eaves-side end of the roof plate 2, and an engaging portion 8 projecting downward by bending is formed. The lower surface (back surface) of the roof plate 2 is lined with the heat insulating material 1. Thus, the roof panel 10 is formed. The suspension 9 is a suspension main body 7 attached to a roof foundation 6.
Is formed by providing an engaging piece 11 on the base plate. The suspension body 7 is formed in a substantially L-shaped cross section by providing a fixing piece 12 at the lower end thereof so as to protrude toward the ridge. Fastening piece 11
Is extended at the upper end of the suspender main body 7 so as to protrude more toward the eaves side than the suspender main body 7. Is provided.

When the roof panel 10 is placed on the roof foundation 6 to form a roof, the roof panel 10 is first placed on the roof foundation 6 and then suspended on the engaged portion 3 of the roof panel 10. The anchoring piece 11 of the child 9 is locked, and then the fixing piece 12 of the hanging element 9 is fixed to the roof foundation 6 on the ridge side of the roof panel 10 with screws or the like, so that the roof panel 10 is It is fixed and attached to the base 6. Next, the engaging portion 8 of the other roof panel 10 disposed on the ridge side of the roof panel 10 is engaged with the engaged portion 3 of the roof panel 10 attached to the roof foundation 6. Thus, the roof panel 10
The roof is formed by sequentially attaching and fixing the roof panel 6 to the roof base 6 while connecting the roof panel 10 and the other roof panel 10 in the eaves ridge direction.

However, since the roof plate 2 is laid on the roof base 6 with the heat insulating material 1 interposed therebetween, the roof material 2 is shrunk (shrinked) due to aging of the heat insulating material 1 or the strength of the heat insulating material 1 is low. Due to the compression, a gap may be formed between the engaged portion 3 of the roof plate 2 and the suspender 9, and the engagement of these members may be weakened or disengaged. There is a fear that sticking will occur or the mounting strength of the roof slat 2 will be reduced. In addition, if the roof plate 2 rattles or the mounting strength is reduced,
There is a problem that the other roof plate material 2 connected thereto has looseness and a decrease in mounting strength. In particular, when the thickness of the heat insulating material 1 is increased in order to enhance the heat insulating performance of the roof, this problem has increased.

Further, since the roof plate 2 is supported by the heat insulating material 1 having relatively low strength, the eaves-side end of the roof plate 2 is lifted by the negative pressure (wind blowing) as shown in FIG. Then, the ridge side end of the roof slab 2 is lowered and the lower heat insulating material 1 is crushed, so that a dent 14 is formed at the ridge side end of the heat insulating material 1. Part 3
In some cases, a gap may be formed between the armature and the hanging member 9 to weaken or disengage the engagement, and as a result, rattling may occur in the roofing sheet material 2 or mounting strength of the roofing sheet material 2 may decrease. There was a fear of doing. Therefore, the moment of the roof plate 2 cannot be increased, for example, the thickness of the heat insulating material 1 cannot be increased, and a roof having high heat insulating performance cannot be formed.

FIG. 8 shows another example of the construction of the roof panel 2 using the roof panel 10. The roof panel 10 is formed by providing a nailing portion 15 on the ridge side of the engaged portion 3. In forming a roof with the roof panel 10, the roof panel 10 is first placed on the roof foundation 6, and then the nail 1 is nailed from the nailing portion 15 of the roof panel 10 to the roof foundation 6.
6, the roof panel 10 is fixedly attached to the roof foundation 6. Next, the engaging portion 8 of the other roof panel 10 disposed on the ridge side of the roof panel 10 is engaged with the engaged portion 3 of the roof panel 10 attached to the roof foundation 6. In this way, the roof is formed by sequentially attaching and laying the roof panel 10 on the roof foundation 6 while connecting the roof panel 10 and another roof panel 10 in the eaves ridge direction.

However, when the roof panel 10 is fixed to the roof foundation 6 by nailing as described above, the roof plate 2 and the heat insulating material 1 at the nailing portion 15 are dented (distorted) by nailing.
The engaged portion 3 of the roof plate 2 may be displaced, and the displacement of the engaged portion 3 may cause another roof plate 2
Cannot be fitted (engaged) with a sufficient strength with the engaging portion 8 of the roof plate 2, and the connection strength between the roof plate 2 and the other roof plate 2 is reduced, so that the roof plate 2 has rattling or a roof. There was a problem that the mounting strength of the plate material 2 was reduced. In addition, due to the displacement of the engaged portion 3, it is not possible to fit (engage) with the engaging portion 8 of the other roof plate 2 without a gap, and the engaged portion of the roof plate 2 and the other roof plate 2 is not engaged. There was a problem that watertightness was reduced.

The hanging member 9 is formed by joining. FIG. 3 (a)
As shown by arrows, the upper and lower suspender main bodies 31 and 32 of the suspender 9 are formed so as to be rotatable about a bent portion 38.

Next, the roof panel 1 using the suspenders 9
The method of laying out the “0” will be described. First, the roof panel 10 is placed on a roof foundation 6 such as a field board so that the engaged portion 3 of the roof plate material 2 faces the ridge side and the engaging portion 8 faces the eaves side, and the roof foundation 6 is insulated. The roof plate 2 is laid with the material 1 interposed therebetween. Next, with the holding pieces 4 and 5 vertically separated from each other, the holding piece 5 of the lower suspender main body 32 is connected to the junction between the heat insulating material 1 and the roof plate 2 from the ridge side end of the roof panel 10 to the lower surface of the bottom portion 51. And the upper surface of the holding piece 5 is brought into contact with the lower surface of the bottom portion 51, and the eave-side surface of the lower suspension body 32 is brought into contact with the ridge-side end surface of the heat insulating material 1.

Next, the upper suspender body 31 is pivoted downward about the bent portion 38 so that the eaves-side surface of the upper suspender body 31 and the ridge-side surface of the lower suspender body 32 are brought into contact with each other. The lower surface of the upper fixing piece 33 of the main body 31 is brought into contact with the upper surface of the lower fixing piece 36 of the lower suspender main body 32, and the groove 50 of the roof plate 2 is further formed.
The fitting portion 40 of the holding piece 4 of the upper suspender body 31 is elastically fitted from above into the lower portion (outer surface) of the fitting portion 40 to form the groove 50.
And the lower surface of the pressing piece 60 of the upper holding piece 4 is pressed against the upper surface of the contacting piece 53 to make contact.

Next, at the part on the ridge side of the roof panel 10, the long screw hole 35 and the lower screw hole 37 of the suspension 9 are formed in the roof foundation 6.
The upper fixing piece 33 and the lower fixing piece 36 of the suspension 9 are fixed to the roof foundation 6 by driving a fixing tool 41 such as a drill screw or a nail through the fixing member 41, and the suspension 9 is attached to the roof foundation 6. Then, the groove 50 of the roof plate 2 is sandwiched from above and below, and the hook 9 is coupled to the roof plate 2. Thus, as shown in FIG.
It can be fixed and attached to.

As described above, since the suspender 9 of the present invention vertically holds the groove 50 of the roof plate 2 with the holding pieces 4 and 5, the lower surface of the roof plate 2 is supported by the lower holding piece 5. The shrinkage (shrinkage) due to the temporal change of the heat insulating material 1 occurs, or even if the heat insulating material 1 has a low strength,
No gap is formed between the groove 50 of the roof plate 2 and the holding pieces 4, 5 of the suspension 9, and the engagement between the groove 50 of the roof plate 2 and the holding pieces 4, 5 of the suspension 9 is weakened. As a result, the roof plate 2 can be prevented from rattling, and the mounting strength of the roof plate 2 can be increased. Since the mounting strength of the roof panel 2 can be increased in this manner, the moment of the roof panel 2 is increased, that is, even if the thickness of the heat insulating panel 1 is increased, the negative pressure causes the roof panel 2 to be mounted on the eaves side. The end portion can be made difficult to lift, and the thickness of the heat insulating material 1 can be increased to form a roof having high heat insulating performance.

By interposing the lower holding piece 5 between the groove 50 of the roof plate 2 and the heat insulating material 1, even if the eaves-side end of the roof plate 2 is lifted by a negative pressure, the ridge of the roof plate 2 is raised. The lowering of the side end portion is prevented by the holding piece 5, so that the heat insulating material 1 is not crushed by the roof slat 2, so that the roof slat 2 can be prevented from rattling and the roof slat can be prevented. 2 can be prevented from lowering the mounting strength.

Further, by laying the roof panel 10 using the hanging member 9 of the present invention, the nailing of the roof plate 2 or the heat insulating material 1 is not required, and the roof panel 2 or the heat insulating material is not nailed. 1 is dented (distorted) 2
Can be prevented from causing displacement. Therefore, the engaged portion 3 of the roof shingle 2 and the engaging portion 8 of the other roof shingle 2 can be fitted (engaged) with sufficient strength, so that the roof shingle 2 rattles and the mounting strength decreases. In addition, the engaged portion 3 of the roof plate 2 and the engaging portion 8 of the other roof plate 2 can be fitted (engaged) without a gap. This prevents the watertightness of the engaged portion of the plate member 2 from being reduced.

Further, the roof plate 2 and the suspension 9 can be connected by elastically fitting the fitting portion 40 of the suspension 9 into the groove 50 of the roof plate 2, and the construction (installation and installation) of the roof plate 2 can be performed. Fixing) can be easily performed, and since the groove 50 is not nailed, there is no possibility that a hole is formed in the groove, and the waterproof property of the roof plate 2 can be prevented from lowering. This eliminates the need for watertight treatment or the like.

Another roof panel 10 is connected and laid on the ridge side of the roof panel 10 laid as described above using a plurality of suspension elements 9. That is, the engaging portion 8 formed on the roof plate 2 of the roof panel 10 on the ridge side is replaced with the roof panel 1 on the eave side.

And the lower surface near the eaves-side end of the roof plate 2 on the ridge side is brought into contact with the upper surface of the projection 24 of the engaged portion 3 of the roof panel 10 on the eaves, and the elastic contact. By engaging the lower surface of the piece 29 with the upper surface of the roof plate 2 in the concave portion 23, the engaging portion 8 of the roof panel 10 on the ridge side is engaged with the engaged portion 3 of the roof panel 10 on the eave side. Thus, as shown in FIG. 1, the roof panel 10 can be connected in the eaves ridge direction.

As described above, the connection structure of the roof panel 2 according to the present invention is based on the roof 3 of the roof panel 10 laid on the ridge side in the engaged portion 3 provided on the roof panel 2 of the roof panel 10 laid on the eaves side. Since the roof plate members 2 arranged in the eaves ridge direction are connected so as to lock the engaging portions 8 formed on the plate members 2, the roof plate members on the eave side whose mounting strength has been increased by the hanging members 9 as described above. By connecting the eave-side end of the ridge-side roof shingle 2 to the ridge-side 2, the mounting strength of the ridge-side roof shingle 2, particularly the ridge-side end of the ridge-side roof shingle 2, can be increased. The roof shingle 2 on the ridge side can be prevented from being lifted by a negative pressure. Therefore, it is possible to prevent rattling of the roof shingle 2 and reduce the mounting strength of the roof shingle 2. Can be prevented.

FIG. 4 shows a method of connecting the roof panels 10 arranged side by side in the width direction of the roof panel 10 (for example, in the direction of the wife). A side end of the roof panel 2 of the roof panel 10 is formed as a connecting portion 41, and a discard plate 49 made of a corrosion-resistant steel plate or the like is disposed between the connecting portion 41 of the roof panel 2 and the heat insulating material 1.
