However, in the case of the above-mentioned folded-plate roof structure, the ceiling plate support 104 has a shape in which support pieces 105, 105 are continuously provided from the lower end opened in an inverted V-shaped cross section to both sides. Since the locking with the plate supporting bracket 101 is only the one in which the displacement in the left-right direction is suppressed by the protruding piece 103,
The force for stopping the ceiling plate support 104 at a fixed position is poor.

[0006] That is, there is room for slight deviation in the left-right direction, and when a negative pressure is applied, the force of the folded-plate roof pressing on the ceiling plate is weakened, and there is a backlash, so that the ceiling plate is easily displaced.

[0007] Further, since the ceiling plate support does not have a structure for locking the ceiling plate, the ceiling plate is merely riding on the folded plate roof until it is pressed by other parts.
For this reason, the ceiling plate may be blown by the wind during the construction work and may be blown away, and if the work until the fixing of the folded plate roof can not be completed on the same day, it is necessary to perform the work again. Was to occur.

Further, since the ceiling plate support has an open lower surface, there is a problem that the appearance is inferior in appearance, and when the environmental condition in the structure is such that steam is likely to be generated, the ceiling plate is not suitable. There was a drawback that water drops concentrated on the support part and accumulated .

[0009]

SUMMARY OF THE INVENTION Accordingly, the present invention prevents the ceiling plate from being displaced by allowing the ceiling plate support to be stopped at a fixed position and by setting the lower surface to a flat surface. It is another object of the present invention to provide a folded-plate roof structure having no difficulty in appearance and use, and a ceiling plate support used therefor.

The means for that purpose will be described. A folded plate support is placed and fixed on a base material, and a long piece is inserted between the protruding piece of the folded plate support in the front-rear direction and the base material. sandwiches the clamped portion formed at a bottom plate made of flat Rana lower surface of the ceiling plate support, passing over on the base material, the edge of the ceiling plate on a support portion protruding to the left and right of the top plate support It is characterized by a folded-plate roof structure in which a ceiling plate is laid down, a folded-plate roof is fixed to the folded-plate support, and the ceiling plate is pressed at a valley of the folded-plate roof.

[0011] In another aspect of the present invention, there is provided a long ceiling plate support in which supporting portions for supporting the edge of the ceiling plate are protruded to the left and right at a lower end. A bottom plate is formed, and two standing pieces sandwiching the projecting member protruding in the front-rear direction of the folded plate supporting bracket on the left and right from above the support portion are provided upright. A holding portion to be sandwiched between the upper and lower members is formed in the middle of the bottom plate, and a tip end side of each of the standing pieces is bent to form a locking portion for locking an edge of an upper surface of the ceiling plate. It is characterized by being a ceiling plate support tool.

[0012] A further configuration is a long ceiling plate support in which support portions for supporting the edges of the ceiling plate are protruded to the left and right at the lower end, and the support portions are connected in a straight line so that the lower surface is flat. A certain bottom plate is formed, and a standing piece is erected upward from between the support portions, and the leading end side of the standing piece is bent to lock the edge of the upper surface of the ceiling plate to be spread right and left. The locking portions are formed, and the height of the upper surfaces of the locking portions is set to a height at which the locking portion can be locked between the protruding piece portion formed on the folded plate support bracket and the base material, and the locking portions are formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing a roof 1. As shown in FIG. 1, the roof 1 has a folded plate support 3 mounted and fixed on a base material 2 made of H steel or the like. Base material 2
The folded plate roof 6 is fixed to the folded plate support 3 with the ceiling plate 5 being spread over the base material 2 by being laid on the top.

The above-mentioned folded plate support 3 is configured as shown in FIG. That is, the locking fitting 8 is placed on the fitting body 7.
The former metal fitting body 7 is formed by bending a band-shaped metal plate into a substantially equilateral trapezoidal shape,
The two holding pieces 9 are erected. A square hole 10 is formed in the center of the holding pieces 9, 9, and a plate-shaped protruding piece member 11 is provided between the holding pieces 9, 9 and a root angle bolt 12 and a washer 13.
, And a spring washer 14 and a nut 15.

The protruding piece member 11 is formed to have a predetermined length required to lock the above-mentioned ceiling plate support 4, and has an elongated hole 16 formed in the length direction. The long hole 16 is for sliding so that the ceiling plate support 4 described later can be easily attached.

Also, the projecting piece portions 17 at both ends of the projecting piece member 11,
17 has a notch 19 at the lower end edge thereof to provide a gap for holding a pinched portion 18 (see FIG. 3) of the ceiling plate support 4 described later. Even if the notch 19 is not provided, the protruding piece member 11 may be raised and attached to such an extent that the above-described gap is formed, but the stability of the protruding piece member 11 is poor. The above-mentioned notch 19 is formed so as to be flush with the lower surface of the metal fitting body 7.

The above-mentioned locking metal member 8 is formed in a dish shape, and locking pieces 21 and 22 extend from upper ends of both right and left sides. The locking piece 21 on the left of the locking pieces 21 and 22 is formed lower than the locking piece 22 on the right as viewed from the front, so that the folded plate roof 3 can be fixed. This latch 8
The root angle bolt 23 is inserted through the square hole 24 of the metal fitting main body 7 and the through hole 25 of the locking metal fitting 8 so that it can be fixed with the washer 26, the spring washer 27 and the nut 28.

As shown in FIG. 3, the ceiling plate support 4 is formed by bending a band-shaped metal plate along the length direction, and substantially corresponds to the length between the base materials 2. It has a long shape with a predetermined length.

The cross-sectional shape is substantially an inverted T-shape, and the left and right sides of a bottom plate 29 having a flat lower surface are support portions 30, 30 for supporting the ceiling plate 5. The portion between the support portions 30 of the bottom plate 29 is the above-described held portion 18 which is sandwiched in the gap between the projecting piece portion 17 and the base material 2. Note that, in FIG. 1, a space is provided for convenience. From both sides of the clamped portion 18, standing pieces 31, 31 are erected so as to sandwich the protruding piece 17 from side to side, and bend their distal ends outward. Thus, locking portions 32, 32 for locking the edge of the upper surface of the ceiling plate 5 are formed.

That is, in order to bridge the ceiling plate support 4 between the base materials 2, the projecting member 11 fixed to the folded plate support 3 is required.
The gap between the upright pieces 31, 31 at the end of the ceiling plate support 4 is fitted to the projecting pieces 17 at both ends of the ceiling plate support 4, and the held portion 18 is placed between the projecting piece 17 and the base material 2. Push it in and pinch it. At the time of fitting, the nut 15 is loosened so that the protruding piece member 11 can be slid, and the ceiling plate support 4 may be located at a predetermined position because it may be from above or below the base material 2. It is preferable that the protruding piece member 11 is slid and fitted, and the nut 15 is tightened.

The protruding piece member 11 may be formed as shown in FIG. 4 so that the nut 15 can be easily locked without loosening or tightening. That is, as shown in FIG. 5, a protruding piece portion 17 having a length L1 that does not protrude from the base material 2 when the folded plate support metal fitting 4 is fixed is formed at one end side of the round hole 33 formed in the intermediate portion. A protruding piece 17 having a length L2 which is about twice that of the protruding piece 17 is formed on the other end side. When the projecting piece member 11 is formed in this way, first, the ceiling plate support 4 is locked to the longer projecting piece 17 as shown by the solid line in FIG. 5, and then the direction shown by the solid arrow. To lock the other end of the ceiling plate support 4. The length of the ceiling plate support 4 is 1 to 2 between the other end and the shorter projecting piece 17 when one end is fully locked to the longer projecting piece 17.
It is good to set so that there is a gap of about mm.

As shown in FIG. 6, the ceiling plate support 4 may be formed by bending the engaging portions 32, 32 at the distal ends of the standing pieces 31, 31 from the outside to the inside. Good.

After fixing the folded plate support 3 configured as described above on the base material 2 and also fixing the ceiling plate support 4,
When the ceiling boards 5 are laid, the joints of the ceiling boards 5 between the base materials 2 use connection support members 34 for the seams as shown in FIGS. 7, 8 and 9. This connection support 34
Is also formed by bending a strip-shaped metal plate along the length direction,
The connection support 34 of FIG. 7 is configured such that one side edge 35a of the bottom plate 35 having a flat lower surface is slightly bent inward, and the other side edge 3a is bent.
5b is also formed by bending inward and then bending at a right angle at an intermediate position to form a standing piece 36. The length of the standing piece 36 is a length corresponding to the thickness between the support portion 30 and the locking portion 32 of the ceiling plate support 4, and the ends are supported by the ceiling plate support 4 as illustrated. It can be placed on the unit 30. That is, it bridges between the ceiling plate supports 4 arranged in the left-right direction.

The connecting support 34 shown in FIG. 8 is cut at both ends and bent at a right angle to form a standing piece 37 at the same height as the standing piece 36 of FIG. In this case, the standing piece 3
The width of 7 is set smaller than the width of the support 30 of the ceiling plate support 4.

The connecting support 34 shown in FIG. 9 is formed by bending both ends of a strip-shaped metal plate at a right angle corresponding to the length between the supporting portion 30 and the engaging portion 32, and erected pieces 34a, 34a, the middle portion bulges downward from a portion separated by the same length as the width of the support portion 30 inwardly of the standing pieces 34a, 34a, and the lower surface of the bulge portion 34b supports the ceiling plate. It is set to be flush with the lower surface of the bottom plate 29 of the tool 4. At this time, side walls 34c, 34c are erected on both side edges of the bulging portion 34b to prevent a gap from being formed between the bulging portion 34b and the ceiling plate 5. In this case, the displacement of the connection support 34 itself is unlikely to occur due to the locking, and the appearance is good because there is no step.

In the roof 1 constructed as described above, first, the folded plate support 3 is fixed on the base 2 by welding, and then the ceiling plate support 4 is hung on the base 2 as described above. hand over. At this time, the clamped portion 18 of the ceiling plate support 4 is clamped between the protruding piece 17 of the folded plate support 3 and the base material 2 to which the folded plate support 3 is fixed. Standing pieces 3
The positions in the left and right directions are fixed by the elements 1 and 31, and the positions are firmly fixed in the vertical direction. For this reason, once the ceiling plate support 4 is hung over the base material 2, it does not come off unless it is intentionally removed, preventing accidental falling off, and interrupting the work at the stage of hung. Even so, there is no problem, and it is possible to avoid a situation where the work has to be redone.

After the ceiling plate support 4 is laid over the base material 2, the ceiling plate 5 is spread over the ceiling plate support 4. At this time, since the ceiling plate 5 is locked and held between the support portion 30 and the locking portion 32, it can be spread tightly. For this reason, the spread state can be maintained even in the case of being blown by the wind, and there is no problem even if the work is interrupted as in the case described above. This effect, coupled with the fact that the ceiling plate support 4 can be firmly extended,
large.

After the ceiling plates 5 have been spread, the folded plate roof 6 is fixed by using the locking metal fittings 8 of the folded plate support metal fittings 3 to form the roof 1. Since the valley 6a of the folded plate roof 6 presses the ceiling plate 5 due to the fixing of the folded plate roof 6, when the vibration occurs due to the earthquake together with the fact that neither the ceiling plate support 4 nor the ceiling plate 5 rattles. Even when a negative pressure due to blowing is applied by a wind or a typhoon or the like, a robust roof 1 in which the ceiling plate 5 does not shift can be obtained.

Further, since the lower surface of the bottom plate 29 of the ceiling plate support 4 is flat, it is possible to prevent the appearance from being poor, and even when a large amount of steam is generated in the structure, the steam is generated. Concentration can be prevented from accumulating to prevent local corrosion, thereby improving durability, and suppressing local water droplets from falling, thereby improving convenience in use.

Each of the two standing pieces 31, 31 has a locking portion 32 for locking an edge of the upper surface of the ceiling plate 5, and a space is provided between the both standing pieces 31, 31. Therefore, it is possible for each of them to be elastically displaced in the left-right direction. For this reason, the locking operation when laying down the ceiling plates 5 can be easily performed, and the shape state is good.

Hereinafter, another embodiment will be described. Folded roof 6
In the case of a flap type, a folded plate support fitting 42 for fixing the hanging member 41 as shown in FIG. 10 may be used. The folded plate support fitting 42 forms a step 44 for fixing the suspension 41 at the upper part of the fitting main body 43, and the root angle bolt 45 is passed through the square hole 43 of the fitting main body 43 and the through hole 47 of the suspension 41. Washer 48, spring washer 49 and nut 50
And fixed using. FIG. 11 is a cross-sectional view of the roof 1 using the folded plate support fitting 42.

FIG. 12 shows the clamped portion 18 of the ceiling plate support 4.
FIG. 4 is a perspective view showing the folded plate support 3 and the ceiling plate support 4 when the setting is made on both ends of the ceiling plate support 4. The ceiling plate folded plate supporting bracket 3 is formed by forming the entire bracket main body 7 into a substantially isosceles trapezoidal shape, and further bending a lower intermediate position into an isosceles trapezoidal shape to form a projecting piece member attaching portion 51. I have. The protruding member mounting portion 51 includes a root angle bolt 52, a washer 53, and a spring washer 5 on a flat surface 51a on the upper surface.
The protruding piece member 11 is mounted using the nut 4 and the nut 55. The protruding piece member 11 is formed in a strip shape having a length corresponding to at least the width of the base material 2, one side edge thereof is bent to form an “H” shape, and a first locking piece 56 is provided. ing. A cut is made at both ends of the other side edge at an appropriate interval, and the space between the cuts is bent at the same angle as one side edge to form a second locking piece 57 (FIG. 13). reference).

The ceiling plate support 4 is formed at a height between the projecting pieces 17 at both ends of the projecting piece member and the base material 2. The cross-sectional shape may be the shape shown in the previous embodiment, but the shape shown in FIG. 12 and FIG. 13 is more convenient for locking since elastic displacement is possible in the vertical direction. good.

That is, the cross-sectional shape of the ceiling plate support 4 is such that a bottom plate 29 having a lower surface as a plane is formed, one side edge thereof is slightly folded, and the other side edge is also folded, and then bent at a right angle at an intermediate position. A standing piece 31 is formed, and the distal end side is bent in order so as to form an isosceles trapezoidal shape, and locking portions 32, 32 are formed on both left and right sides, respectively. The upper isosceles trapezoid is formed by the first locking piece 56 of the protruding piece member 11 and the second locking piece 56.
It corresponds to the inclination with the locking piece 57, and forms a locking inclined surface 58 that enables the above-described locking.

Alternatively, a ceiling plate support 4 having a sectional shape as shown in FIGS. 14 and 15 may be formed. In the ceiling plate support 4 of FIG. 14, the tip side of the standing piece 31 is formed in a round shape, and an appropriate gap is formed between the leading edge and the upper end of the standing piece 31. In this case, the distance between the first locking piece 56 and the second locking piece 57 of the above-mentioned protruding piece member 11 may be set to a narrow width that can prevent displacement in the left-right direction. When the cross-sectional shape on the tip side of the standing piece 31 is round as described above, the dropping work for supporting the ceiling plate 5 can be performed extremely smoothly. This is due to the action of the curved inclined surface 58 on the upper surface and the gap between the leading edge and the upper end of the standing piece 31.

When the tip of the standing piece 31 is rounded, two standing pieces 31 are formed at appropriate intervals as in the above-described embodiment, and this tip is shown in FIG. It may be formed to be semicircularly curved from the outside as shown or from the inside as shown in FIG.

In the ceiling plate support 4 shown in FIG. 15, the front end of the standing piece 31 is bent in a quadrangular shape. In this case, the interval between the first locking piece 56 and the second locking piece 57 of the protruding piece member 11 is set so as to correspond to the width of the upper surface. In the case of the ceiling plate support 4 of FIG. 15, the inclined surface 58 is not formed, but the ceiling plate support 4 is easily formed by the set angle and the curvature of the first locking piece 56 and the second locking piece 57 of the protruding piece member 11. It is possible to attach the ceiling plate support member 4 to a predetermined position after loosening the protruding piece member 11 in advance, and then tighten the protruding piece member 11 to perform the mounting.

In the case where the folded plate support 3 and the ceiling plate support 4 are configured as described above, when the ceiling plate 5 is bridged between the base materials 2, as shown by arrows in FIG. Perform by locking. Therefore, the work can be performed easily and smoothly without leaving the length of the ceiling plate support 4 too long.

That is, each of the locking portions can be elastically displaced in the left-right direction, and at the same time, the upright piece 31 and the vertical direction at the boundary portion between the upright pieces 31 and the locking portions 32, 32. Since the elastic displacement is also possible, the locking work when laying down the ceiling plate 5 is easy, the locking state is good, and the right and left with respect to the lower side of the projecting piece portion 17 when bridging over the base material. Locking from a direction can be easily performed, and a strong locking state can be obtained.
