Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folded roof plate mounting structure in which a folded roof plate is mounted on a base material for a roof via a tight frame, and a tight frame for mounting the folded roof plate.

[0002]

2. Description of the Related Art As a mounting structure for this type of folded roof plate,
For example, as shown in FIG. 20, a protruding claw piece 41 is provided near the top of a tight frame 40 fixed to a base material 1 such as a roof beam or a purlin, and a rising side plate 43 of a folded roof plate 42 is provided on the protruding claw piece 41. There is a method of fitting and locking the locking projection 44 provided on the (for example, Japanese Utility Model Publication No. 57-53773).
(See the official gazette). At the time of locking, as shown in FIG. 21, first, the bottom plate 45 of the folded roof plate 42 is attached to the tight frame 4
The projection claw pieces 41 of the tight frame 40 are fitted into and locked by the projections 44 by pushing down the projections 44 and then to the troughs 46 of 0. According to this, since the projecting portion 44 of the folded roof plate 42 is fitted and locked to the projecting claw piece 41 of the tight frame 40, the folded roof plate 42 is attached at the fastening portion thereof without using the hangings. It is possible,
Further, it is possible to prevent the folded roof plate 42 from scattering due to a negative pressure load.

[0003]

However, the protruding portion 44 of the origami roof plate 42 is replaced by the protruding claw piece 41 of the tight frame 40.
In the mounting structure of the folded roof plate which is fitted and locked to, the bottom plate 45 of the folded roof plate 42 is dropped into the valley portion 46 of the tight frame 40, and then the elasticity of the rising side plate 43 of the folded roof plate 42 is increased. It is necessary to forcibly push down the protruding portion 44 with a strong force against this, and therefore, there is a possibility that the protruding claw piece 41 may scratch or deform near the lower portion of the protruding portion 44 of the origami roof plate 42. However, it is difficult to perform such an unreasonable fitting / locking operation with the folded roof plate 42 having a low elasticity. I mean,
When the protruding amount of the protruding claw piece 41 is reduced so that the fitting work can be easily performed, the locking force with the protruding portion 44 is reduced to half, and therefore, when the negative pressure load is largely applied to the folding roof plate 42, it is tight. It becomes easy to come off from the frame 40.

Therefore, an object of the present invention is to smoothly and easily fit and lock the folded roof plate to the tight frame, thereby facilitating the installation work of the folded roof plate.

Next, the procedure for attaching the folded roof plate 3 will be described. The tight frames 2 are arranged on the base material 1 at predetermined intervals, and the left and right seat plate portions 1 of each lower frame 10 are arranged.
4 is fixed to the base material 1. As shown in FIG. 3, under the state where the upper frame 11 is stationary at the neutral position on the lower frame 10 (the state of the chain line M), the adjacent folding plate roof plates 3,
The valley bottom plate 4 of one of the folding roof plates 3 which is to be roofed first is dropped into the valley part on one side between the tight frames 2 and 2. With this drop, the fitting ribs 6 of the folded roof plate 3
While sliding down on the inclined side plate portion 16 on one side of the upper frame 11 and horizontally moving the upper frame 11 on the lower frame 10 in the right direction R of the other folding plate 3, the inclined side plate portion is It is fitted and locked to the protruding fitting portion 18 below the 16. Therefore, the fitting ribs 6 of one of the folding plates 3
Can be smoothly fitted and locked to the protruding fitting portion 18 of the inclined side plate portion 16 on one side of the upper frame 11.

Next, as shown in FIG. 4, as the trough bottom plate 4 of the other folding roof plate 3 is dropped into the trough on the other side between the tight frames 2 and 2, the folding roof plate 3 thereof is dropped. While the fitting rib 6 of the above slides down on the inclined side plate portion 16 on the other side of the upper frame 11, the upper frame 11 is moved in the opposite direction L
When the fitting rib 6 is pushed back to the original neutral position, the protruding fitting portion 18 below the inclined side plate portion 16 on the other side.
Fit and lock. Therefore, while securing the fitting state of the fitting rib 6 of the one folding roof plate 3 and the protruding fitting portion 18, the fitting rib 6 of the other folding roof plate 3 is also provided on the other side of the upper frame 11. It is possible to smoothly and easily and surely fit the protruding fitting portion 18 of the inclined side plate portion 16 without difficulty.

Thus, the fastening pieces 8 of the thus-attached folding roof plate 3 are adjacent to each other as shown in FIG. 1 by fastening the fastening pieces 8 of the folding roof plate 3 previously attached. The origami roof plates 3 and 3 are connected to each other. In this way, the roof can be roofed by sequentially tightening the folded plate 3 fitted to the tight frame 2.

Folded roof plate 3 attached as described above
The horizontal plate portion 7 is the rising portion 13 of the lower frame 10.
By being supported by the top plate portion 15 of the upper frame 11 which is received and supported by the top portion 13a of the upper frame 11, it is possible to sufficiently oppose a positive wind load, and the fitting ribs 6 project from the upper frame 11. By being fitted and locked to the fitting portion 18 and supported, high strength against negative wind pressure can be obtained,
Sufficiently counters both positive and negative wind loads. The fitting rib 6 is provided at a position on the lower side of the inclined side plate 5 as much as possible, and is effective in countering even a negative pressure load that is large in fitting and locking with the protruding fitting portion 18, and is difficult to remove. preferable.

In the folded roof plate 3, the inclined side plate 5 is provided with the fitting rib 6 having a V-shaped cross section, so that the resistance against bending deformation is also increased. Further, the shape of the fitting rib 6 portion of the folded roof plate 3 is such that the lower end portion of the rib slope plate 6b and the end portion of the valley bottom plate 4 are connected via the inclined side plate lower portion 9 having substantially the same slope as the inclined side plate 5. That is, the rib slope plate 6b and the inclined side plate lower portion 9 are formed in a dogleg shape. According to this
Looking at the deformation process when a negative pressure is applied, as shown in FIG. 6, the valley bottom plate 4 is curved and deformed to bulge outward (broken line state), and the angle formed by the rib slope plate 6b and the inclined side plate lower part 9 is formed. A,
The angle B formed by the lower inclined plate 9 and the valley bottom plate 4 increases, but the angle C formed by the rib upper surface plate 6a and the rib slope plate 6b decreases, and the dimension X from the allocation core S to the fitting rib 6 increases.
Does not change, it is possible to suppress the bending deformation such that the rib upper surface plate 6a of the fitting rib 6 rotates around the connecting portion with the lower end portion of the inclined side plate 5, that is, the deformation of the valley bottom plate 4 is prevented. It is possible to prevent the transmission to the 6a, and it becomes difficult for the folded roof plate 3 to come off from the tight frame 2.

On the other hand, as in the folded roof plate 3 shown in FIG. 7, for example, the fitting rib 6 is connected to the rib upper plate 6a and the end of the valley bottom plate 4 by the inclined side plate lower portion 9 in a straight line. In the shape, the valley bottom plate 4 bends when negative pressure is applied,
The angle B formed by the inclined side plate lower portion 9 and the valley bottom plate 4 and the angle D formed by the upper portion of the rib upper surface plate 6a and the lower portion of the inclined side plate 5 increase, and the dimension X increases. The rib top plate 6a may be bent and deformed so as to rotate around the connecting portion with the inclined side plate 5, and the folded roof plate 3 may come off from the tight frame 2. Therefore, it can be said that the folded roof plate 3 having the sectional shape shown in FIG. 6 is preferable to that shown in FIG. 7.

When the roof has a slope, the upper frame 11 and the lower frame 10 are adjusted so as to correspond to the roof slope.
With respect to the horizontal axis 28. Therefore, as shown in FIGS. 8 and 9, the upper frame 1
The reference numeral 1 integrally forms a gate-shaped rising portion 25 that covers the outside of the gate-shaped rising portion 13 of the lower frame 10 between the left and right bottom plate portions 19 and 19, and forms the bottom plate portion 19 in an arc-shaped cross section. . Then, holes 26, 2 are formed in the rising portion 25 of the upper frame 11 and the rising portion 13 of the lower frame 10.
7 are provided on the same axial center, a horizontal shaft 28 made of a head bolt is inserted into the holes 26 and 27, and a nut 29 is screwed into the threaded end of the horizontal shaft 28.
1 is rotatably connected to the lower frame 10 about a horizontal axis 28. In this case, the diameter of the hole 27 of the lower frame 10 is formed larger than the diameter of the horizontal shaft 28 so that the horizontal movement of the upper frame 11 on the lower frame 10 is not hindered.

The upper frame 11 of this embodiment is slightly different from the upper frame 11 of the above embodiment, and the top plate portion 1
5 is formed on the top of the rising portion 25, and the upper end plate portion 16a of the inclined side plate portion 16 forming the protruding fitting portion 18 is formed on the rising portion 25.
It is bent substantially horizontally toward and is formed in an edge cut state with the top plate portion 15. The top plate portion 15 of the rising portion 25 is received and supported by the top portion 13a of the rising portion 13 of the lower frame 10. Further, a gap (for example, about 2 mm) is formed between the tip 16b of the substantially horizontal upper end plate portion 16a of the inclined side plate portion 16 and the rising portion 25. Thus, the tip 16b of the upper end plate portion 16a that forms a gap with the rising portion 25 hits the rising portion 25 when a negative pressure load is applied, so that the deformation of the upper frame 11 can be prevented and strengthened. This is shown in FIGS.
The same applies to the tight frame 2 shown in FIG.

In addition to the above-mentioned shape, the tight frame 2 may be formed in a shape as shown in FIGS. In the tight frame 2 shown in FIG. 10, the lower frame 10 has the same shape as the lower frame 10 shown in FIG. 1, but the upper frame 11 does not have the bending piece 17 like the upper frame 11 shown in FIG. A protruding fitting portion 18 is formed at a corner where the portion 16 and the bottom plate portion 19 intersect.

The tight frame 2 shown in FIG. 11 differs from the lower frame 10 shown in FIG. 1 in that the lower frame 10 is formed in a shape without a rising portion 13, and the upper frame 11 is an upper frame shown in FIG. It is substantially the same as the shape of 11. The tight frame 2 shown in FIG. 12 is different from the tight frame 2 shown in FIG. 8 only in that they are not connected by the horizontal shaft 28 and that the upper frame 11 is formed in a shape without the bending piece 17, and other than that, Have the same shape. The lower frame 10 such as the tight frame 2 shown in FIG.
