As for the thickness of the metal folded plate used for these roofs, a thin iron plate is usually used with a thickness of about 0.6 to 0.8 mm. With this thickness, in the panel support structure of the metal roof described in the above cited reference 1 and cited reference 2, if the folded plate is struck by a strong wind such as a typhoon only by providing a dedicated metal fitting at the mountain part of the folded plate, In some cases, the welded portion with the metal beam material that fixed the valley portion of the folded plate peeled off, or the peak portion that fixed the panel could not withstand the strong wind and was deformed or damaged.
In addition, under the influence of the breakage of the folded plate, the panels such as the photovoltaic power generation panel and the signboard installed thereon may be damaged.

  Therefore, an object of the present invention is to fix the folded plate to the beam material having high strength of the building, and also to fix the panels such as the photovoltaic power generation panel and the signboard installed on the beam material, An object of the present invention is to provide a strong panel support structure in which a folded plate, a photovoltaic power generation panel, and the like are not damaged even if the wind is blown by a strong wind.

  In order to solve the above problems, the panel support structure in the folded metal roof of the present invention is welded to the upper surface of the flange on the upper side of the H-shaped steel in which the corrugated tight frame having the upward bolt on the mountain portion is the beam of the building. In the folded metal plate roof where the corrugated folded plate covering the ceiling of the building is fitted to the upward bolt and the bolt hole provided in the mountain line of the folded plate is fixed, the bolt hole of the mountain line of the folded plate is The upper threaded part protrudes from the folded plate through the bolt holes drilled in the part directly above the both sides of the H-shaped steel flange on both sides sandwiched, and the lower part is engaged with both sides of the flange lower surface 2 Three bolt holes that match the locking bolts and the bolt holes are formed, and the folding plate is fixed by a fixing nut that is screwed to the locking bolt and the upward bolt that protrudes above each bolt hole.

  The panel support structure in the metal folded plate roof of the present invention can be fixed directly to the H-shaped steel beam with a fastening bolt, and the thin folded plate has a large area between the upper surface of the tight frame and the lower surface of the three-hole washer plate. It comes into contact and is squeezed with a fixing nut and pressed to secure the surface. With such fixing, the H-shaped steel and the folded plate, the tight frame and the three-hole washer plate are integrated, and the H-shaped steel is supported by the tight frame in the beam direction and supported by the fastening bolt in the folding direction of the folded plate. Can be supported firmly. As a result, a strong structure capable of widely dispersing the load generated in the four directions due to strong winds and the like into the four directions can be obtained, thereby preventing the panel support portion from being deformed or damaged.

  Next, by covering the three-hole washer plate with a hard rubber packing, it is pressed down with flexibility including the peripheral area of the ridges of the folded plate. The rubber packing that is hard even with the fixing nut is tightened face-to-face to prevent deformation and alteration of the hard rubber packing, and the pressing force of the hard rubber packing to the folded plate is made uniform. Therefore, it is possible to flexibly cope with loads caused by strong winds that occur intermittently, and it is possible to prevent deformation and destruction of the panel support structure.

An embodiment of a panel support structure such as a photovoltaic power generation panel in the folded metal roof of the present invention will be described.
In large buildings with large floor areas, such as warehouses, factories, and gymnasiums, many roofs are scooped with a metal corrugated folded plate in a crease (fold) direction.
In the present invention, among such metal folded plate roofs, as shown in FIG. 1 (columns, wall portions, etc. are omitted), H-shaped steel 1 is used as the beam material of the building, and the flanges of the H-shaped steel are vertically moved. The target is a folded metal roof with a combined structure.
Although the structure of the present invention can be used for a newly built building, since the construction process can be performed entirely on the roof as described below, there is no need for a person to enter the back of the ceiling. It is possible to form a panel support structure without removing the roof from the roof of the building.

  In addition, since this invention is invention of the metal folded-plate roof part of a building, in the following each figure which shows an Example, the pillar of a building, a wall part, etc. are abbreviate | omitted and the internal structure is hidden with a metal folded plate. Since it is difficult to understand, each figure depicts the folded plate transparently.

Hereinafter, the panel support structure in the metal folded-plate roof of this invention is demonstrated in detail with the figure which shows an Example.
As shown in FIGS. 1 and 2, the present invention is formed on the upper surface 2 a along the web of the upper flange 2 of the H-section steel 1 that is a beam of a building so as to overlap with the waveform of the folded plate 4. The tight frame 3 is disposed so as to lie in the longitudinal direction, and the valley portion 3a of the tight frame 3 is welded and fixed to the upper surface 2a of the flange 2. A symbol S in FIG. 2 is a spot welded portion.
An upward bolt 6 projecting upward is fixed to the upper surface of the peak portion 3 b of the tight frame 3. The corrugated folded plate 4 is arranged on the upward bolt 6 in a direction in which the inclined folding line 5 is orthogonally different from the H-section steel 1.
And the bolt hole 4c is opened in the position where the said upward bolt 6 agree | coincides, the upward bolt 6 is inserted in this bolt hole 4c, and the corrugated folded board 4 which covers the ceiling of a building is rolled.
The structure so far is also the structure in the existing folded metal roof.
In the case of construction on an existing roof, a nut is screwed onto the corrugated folded plate 4 and the metal folded plate 4 is fixed to the flange of the H-section steel 1 through the tight frame 3 in the existing roof. In the present invention, all nuts and washers that fix the folded plate 4 to the tight frame 3 are removed.

Next, as shown in FIG. 4, in the center of the crest surface of the crest 4 b of the folded plate 4 placed on the tight frame 3 from the position of the bolt hole 4 c for fixing to the tight frame 3. A pair of bolt holes 8, 8 are provided at equal distances and at an interval equivalent to the width W of the flange 2. That is, the position of the pair of bolt holes 8, 8 is a portion that is directly above both sides of the flange 2 on the upper side of the H-shaped steel and is a portion in the center of the mountain line of the folded plate 4.
Then, from above the pair of bolt holes 8, 8, the engaging bolts 7, 7 having the screw portion 7 b on the upper side are inserted with the engaging portion 7 a facing downward. The engaging portions 7a of the engaging bolts 7 and 7 may be hooked to the lower surface of the upper flange 2 of the H-shaped steel, and thus are formed in an inwardly curved shape such as an “L” shape or a “shi” shape. It is also possible.
At this time, the upper screw portions 7b and 7b of the L-shaped engaging bolts 7 and 7 and the upward bolt 6 are in a state of protruding onto the folded plate 4 as shown in FIG.
Therefore, next, as shown in FIGS. 1 and 4, bolt holes 9 a, 9 b, 9 c provided at plate surface positions that coincide with both screw portions 7 b, 7 b of the upward bolt 6 and the engaging bolts 7, 7 are provided. A three-hole washer plate 9 having three holes is fitted into the screw portions 7b and 7b of the upward bolt 6 and the engaging bolt 7, and the upward bolt 6 and both screw portions 7b protruding above the three-hole washer plate 9 are fitted. , 7b are fitted into the washers 10 and 11, and the fixing nut 12 is screwed onto the washers 10 and 11 and tightened strongly.

  At this time, the engaging portion 7a is fixed by the fixing nut 12 in a state where it strongly presses the lower surface 2b of the flange 2 on the upper side of the H-shaped steel 1, but the engaging portion 7a of both engaging bolts 7 is the H-shaped. In order to confirm that the direction of the tip of the engaging portion 7a on the lower surface 2b of the flange 2 on the upper side of the steel 1 is the center direction of the H-shaped steel 1, the upper end portions of the two engaging bolts 7 are used. If a mark (not shown) is attached to one portion in the direction of the engaging portion 7a with a colored writing instrument or the like, the direction of the tip of the engaging portion 7a that cannot be seen from the top of the roof can be confirmed.

Thus, the folded plate 4 is firmly fixed in a state where it is sandwiched by a wide area between the upper surface of the tight frame 3 and the lower surface of the three-hole washer plate 9.
Usually, the folded plate 4 is thin and weak at 0.5 to 0.8 mm. For this reason, there is a possibility that the part will be easily damaged due to concentration of force when it receives a pressure with a change in which pressure reduction and pressurization are repeatedly applied to the roof receiving wind pressure at one point. By widely dispersing the pressure in a plane, it is possible to prevent the folded plate 4 from being damaged even when subjected to a strong wind pressure without causing the folded plate 4 to be deformed.

Next, from the top of the three-hole washer plate 9, it is formed in a thick and downward U-shape, and is provided at a position that matches the threaded portions 7b and 7b of the upward bolt 6 and the locking bolts 7 The hard rubber packing 13 having the bolt holes 17 and the bolt holes 15 and 16 on both sides thereof (shown in FIG. 3, (A) is a perspective view, (B) is a longitudinal perspective view, and (C) is inverted) (It is a perspective view) and is installed so that the bolt holes 15 and 16 on both sides are penetrated and covered with the upward bolt 6.

Therefore, the hard rubber packing 13 is thicker than the length of the upward bolt 6, and the bolt holes 15, 16 on both sides are formed on the lower side with a diameter larger than the upper part so that the fixing nut 12 can be accommodated.
The rubber packing 13 is made of hard rubber that is so hard that it hardly deforms even under a small pressure.

Then, a packing presser plate 18 having bolt holes 19 and 20 is fitted from above the engaging bolts 7 and 7 protruding above the rubber packing 13 to a position corresponding to the upper position of the engaging bolts 7 and 7. Include.
The packing retainer plate 18 is made of a metal plate formed in a metal downward U-shape that covers the entire upper surface of the hard rubber packing 13, and the screw portions 7b, 7b of the engagement bolt 7 are connected to the bolts. The holes 19 and 20 are attached so as to be covered.
Then, washers 21 and 22 are fitted from above the screw portions 7b and 7b protruding upward to the packing presser plate 18, and the fixing nuts 23 are screwed together. As shown in FIG. Tighten and fix the upper surface around the peak 4 to press down.
As described above, each of the members to be used is firmly fixed to the upper surface of the tight frame 3 and the flange 2 on the upper side of the H-shaped steel 1 below the fastening bolts 7 and 7.

Various panels can be fixed on the panel support structure of the folded plate roof of the present invention configured as described above, but when fixing a photovoltaic power generation panel, the panel is a photovoltaic power generation panel. In this case, the upper and lower frames are fixed to the screw portions 7b and 7b of the engaging bolt 7 projecting between the beam members of the upper and lower H-shaped steel 1 with a fixing nut or the like.
Next, when an example in the case of fixing a photovoltaic power generation panel is given, as shown in FIG. 6, the photovoltaic power generation panel is composed of an inner photovoltaic power generation module 24 and an outer peripheral photovoltaic power generation panel frame 25. The photovoltaic panel frame 25 is fixed.
The photovoltaic panel frame 25 is fixed to the engaging bolts 7 and 7 in which the bent portion 7a is fixed to the H-section steel 1 in the panel support structure of the present invention and the screw portions 7b and 7b protrude from the packing presser plate 18. The
It is also possible to directly fix the photovoltaic power generation panel to the threaded portions 7b, 7b of the engaging bolt 7. In this case, the photovoltaic power generation panel is positioned at the position of the threaded portion 7b of the engaging bolt 7. Must match.
However, since the size of the photovoltaic power generation panel is not necessarily unified by each manufacturer, it is usually fixed via a mounting bracket that can support the panel frame according to the size and the mounting angle of the panel.

In the embodiment of FIG. 6, the solar power generation panel is configured to be tilted and fixed, and therefore an inclined fixing bracket 26 in which both sides are bent obliquely is interposed.
The inclined fixing bracket 26 is removed from the fixing nut 23 so as to be in close contact with the packing retainer plate 18, and the threaded portion 7 b of the engaging bolt 7 is passed through the bolt hole 26 a provided in the inclined fixing bracket 26. It is fixed on the presser plate 18.
