Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for attaching a folded sheet roof plate to form a folded sheet roof, and more particularly, to mounting a folded sheet roof sheet so as to obtain a folded sheet roof having a heat insulating effect. TECHNICAL FIELD The present invention relates to a metal fitting and a folded plate roof structure using the metal fitting.

[0002]

2. Description of the Related Art A folded plate roof having a heat insulating effect is formed by forming a lower roof and then laying a heat insulating material such as glass wool and then forming an upper roof. At this time, a mounting bracket that prevents heat conduction in the vertical direction is used.

The mounting member is formed by combining a highly rigid metal member and a heat insulating synthetic resin member. That is, as shown in FIG.
00 is a lower metal holding / fixing portion 10 for holding and fixing the roof fastening portion 101a of the lower roof 101 made of a folded sheet roof plate.
2 and a metal suspension 104 at the upper end for locking and fixing the folded roof plate for forming the roof 103, a heat insulating member 105 made of synthetic resin is interposed. .

A heat-insulating roof can be obtained by using this mounting bracket 100. As described above, the hanging member 104 is used to fix the folded-plate roof plate, and the edge of the folded-plate roof plate is engaged. The construction is not difficult, but there were some difficulties in terms of strength in windy areas, areas with many typhoon damage, and areas with many earthquakes.

By the way, as a fixing method without using the hanger 104, there is a structure disclosed in the rear of Japanese Utility Model Publication No. 57-53773. As shown in FIG. 13, the locking ribs 107 protruding inward and outward are bulged at a part of the rising portions 106b that are diagonally raised from the left and right sides of the horizontal bottom plate portion 106a in the folding plate roof plate 106. It was formed.
By forming the locking piece 108 that locks on the locking rib 107 on the mounting member 109, high strength can be obtained.

However, if the engagement between the engagement rib 107 and the engagement piece 108 is loose, the strength is lowered, and if the engagement is tight, the construction is difficult, resulting in a contradiction. That is, in order to obtain high strength, the locking width is inevitably large, but if so, the folding roof plate 106 must be largely deformed during the locking work. In addition to the difficulty of work, the need for large deformation also has a drawback that the coating film of the folded roof plate 106 is peeled off or the folded roof plate 106 is bent.

[0007]

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide a folded plate roof plate mounting fixture and a folded plate roof structure which have high mounting strength and can be easily constructed.

Next, another folded-plate roof plate is dropped from the top to the other side (right side) of the folded-plate roof plate mounting bracket and locked. At this time, the locking member is slid from the protruding state and pushed in to secure the locking between the locking portion at one end of the locking member and the folding plate roof plate. Then, by dropping the folding plate roof plate, the folding plate roof plate is locked to the locking portion at the other end of the locking member while sliding the locking member.

As described above, the locking member of the folding plate roof plate mounting member and the folding plate roof plate are locked with each other without the deformation of the folding plate roof plate being too strong due to the sliding of the locking member. With a wide locking width.

The fixed portion may be a fastening portion of the folded roof plate. It is possible to obtain a heat-insulating roof including a lower roof and an upper roof.

On the lower surface of the main body member, there is formed an accommodating space into which the fastening portion of the folded roof plate is inserted, and the fixing metal fitting is divided into left and right parts, and a sandwiching piece which horizontally enters the accommodating space from the left and right sides. It is preferable to form a holding portion that holds the fastening portion in front of and behind the main body member. Firmly fixed to the roof-type roof of the snack-type.

The engaging portion of the engaging member may be set to engage with an engaging rib formed under the rising portion of the folded roof plate. This is because if the engaging rib is at the bottom, the deformation in the vicinity of the engaging rib when the roof receives a negative pressure is small, and higher fixing strength can be obtained.

Another means is a folded plate roof structure using the folded plate roof plate mounting metal fitting according to any one of claims 1 to 4.

Still another means is a folded plate roof structure formed by interposing a heat insulating material between the lower and upper roofs, wherein the lower roof is a frame-shaped main body member, The sliding roof is formed by using a locking member having a locking portion that locks the folded roof plate by sliding right and left on the main body member. A folded-plate roof structure formed by using the folded-plate roof plate mounting bracket according to any one of the above. In addition to forming the upper roof, the lower roof can also be formed by the main body member and the slidable locking member.

Subsequently, the folded roof plate 4 is fixed to the tight frame 3 from the left side. That is, the right side of the folded plate roof plate 4 is lowered from the upper side with respect to the left side of the tight frame 3 so that the engaging rib 4a of the folded plate roof plate 4 is locked by the locking piece 38 portion on the left side of the locking member 35. At this time, since the locking member 35 slides to the right, deformation of the folded roof plate 4 during locking is suppressed. Continuing on, the left side of another folding plate roof plate 4 is locked to the right side of the tight frame 3, but this is also the case.
Since the locking member 35 slides to the left, the engaging rib 4a can be locked to the locking piece 38 portion with the deformation of the folding plate roof plate 4 being reduced. After that, the engaging portion 4 of the adjacent folding plate roof plate 4
e and 4f are engaged with each other to form the fastening portion 5a.

After forming the lower roof 5 in this way,
The mounting member 1 is fixed to the fastening portion 5a. The fixing is performed by sandwiching between the sandwiching piece 21 and the two sandwiching portions 24, so that a strong fixed state can be obtained.

Next, after laying a heat insulating material, the folded roof plate 4 is dropped onto one side (left side) of the mounting member 1 from above and locked.

Subsequently, another folded plate roof plate 4 is dropped onto the other side (right side) of the mounting member 1 from above and locked.
At this time, the locking member 10 is slid from the protruding state and pushed in to ensure the locking between the locking portion 30 at one end of the locking member 10 and the previous folding plate roof plate 4. You should do it later. Then, by dropping the folding plate roof plate 4, the folding plate roof plate 4 is locked to the locking portion 30 at the other end of the locking member 10 while sliding the locking member 10.

At this time, the locking member 10 of the mounting member 1
However, the engaging portions 30 on both the left and right sides lock the engaging ribs 4a of the adjacent folding plate roof plates 4 and 4, and the allocating metal fittings 14 held by the main body member 8 form the adjacent folding plate roofs. The positions of the upper ends of 4, 4 will be restricted. Finally,
By engaging the engaging portions 4e and 4f of the adjacent folding plate roofs 4 and 4 with each other, the roofing roof 7 having a high fixing strength by reliable locking is formed.

As described above, the locking member 1 of the mounting member 1
Since the locking member 10 slides, the 0 and the folding plate roof plate 4 can be easily attached without damaging the folding plate roof plate because the locking member 10 slides.

Further, since the main body member 8 is made of synthetic resin and the locking member 10 is not in contact with the fixing metal fitting 9 for fixing the main body member 8, it is possible to obtain a roof having a heat insulating effect as described above. it can. Further, since the sliding locking member 10 is held by forming the holding space 15 in the main body member 8 made of synthetic resin, friction resistance is small and sliding is smooth.

In the above example, the insulated double roof formed by folding the folded roof plate 4 into upper and lower double layers is taken as an example. However, for example, the mounting member 1 is fixed on the base material and the heat insulation is performed. It is also possible to obtain a roof structure in which the folded sheet roof plate 4 is single-roofed and formed so that the folded sheet roof plate 4 is fixed to the mounting bracket 1 by laying boards having soundproofing effect. Further, it is not always necessary to form a roof having a heat insulating effect, and the locking member 1 is attached to the main body member 8 made of synthetic resin as described above.
Since 0 can be slidably held, smooth sliding is possible, so that an effect that the construction work is easy can be obtained.

[0047]

As described above, according to the present invention, since the locking member of the folding plate roof plate mounting bracket slides to the left and right when locking the folding plate roof plate, the mounting work is simple. In addition, it is possible to suppress the deformation of the folded sheet roof plate as much as possible at the time of locking, and it is possible to prevent the folded sheet roof plate from being damaged such that the coating film is peeled off or bent. Moreover, it is possible to obtain a sufficient locking width for locking. That is, it is possible to easily perform the attachment with high fixing strength without damaging the folded roof plate.

Further, since the main body member is made of synthetic resin and the locking member is not in contact with the fixing metal fitting for fixing the main body member, a roof having a heat insulating effect can be obtained.

Moreover, since the sliding locking member is held by forming the holding space in the main body member made of synthetic resin, the frictional resistance is small and the sliding is smooth.
