Abstract

PURPOSE:To increase strength by forming a reinforcing side of a long frame material along the longitudinal direction of a long surface plate out of a projected side projected toward an indoor side and a parallel side in parallel with the surface plate, and forming them into a hollow type. CONSTITUTION:An upper rail 6 and a lower rail 7 facing laterally in right and left directions are fixed to the upper and lower parts of long surface plate 5 of wave form, etc., respectively, and a vertical frame 8 is fixed to an indoor side. Next a projected side 7b is installed protrusively from a rail main body 7a to the indoor side, and a parallel side 7c roughly in parallel with a plate 5 is installed extendedly to its top to provide a reinforced side. Also the sides 7b and 7c are formed into a hollow type. Then a panel material 2 on which the rails 6 and 7 are provided is connected by hinges 10 to form a shutter curtain. Then, when the panel material 2 receives wind pressure from the indoor side, the reinforced side part of the rail 7 receives a compressive load. However, since the load is received by the hollow follow type sides 7b and 7c, the conventional meander and bucking can be prevented from occurring. Thus the strength against the wind pressure from both indoor and outdoor sides can be increased surely.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel material for a panel shutter which can be opened and closed in an opening of a building.

[0002]

BACKGROUND OF THE INVENTION Generally,
Some of this kind of panel material is formed by framed frame on the back surface of a plate material such as steel plate.In such a material, it is required to improve the strength and wind pressure. It Therefore, conventionally, as shown in FIG. 10, a substantially L-shaped frame member 11 is provided, and a reinforcing side 11 protruding toward the indoor side of the frame member 11 is used.
Attempts have been made to increase the strength by using a as a plate-shaped reinforcing side. By the way, it is necessary for the panel to withstand the wind pressure from both inside and outside,
The reinforcement side 11a receives a wind pressure from the outdoor side, that is, a load in a pulling direction when the panel receives a wind pressure in a direction to enter the indoor side, and conversely, a wind pressure from the indoor side (in a direction in which the panel exits to the outdoor side). With respect to wind pressure), the load is applied in the direction of compression. However, as described above, when the reinforcing side is a flat plate, the reinforcing side is strong against the load in the pulling direction, but meanders or buckles with respect to the load in the compressing direction, so that the reinforcing side is strong. Inferiorly, there is a problem that this tendency becomes more remarkable as the panel length becomes longer.

Therefore, as shown in FIGS.
Parallel side 12a so that it is substantially parallel to the panel surface at the protruding end of
It has been attempted to integrally form the above to improve the wind pressure strength from the indoor side, but even with this configuration, the wind pressure strength from the indoor side is still the same as the wind pressure strength from the outdoor side. On the other hand, about 70 to 80% is good, and some things are less than 50%.

DISCLOSURE OF THE INVENTION The present invention was devised with the object of providing a panel material for a panel shutter that can eliminate these drawbacks in view of the above-mentioned circumstances. A panel material for a shutter is displayed in a state of being orthogonal to the long surface plate, a plurality of long first frame members integrally provided on the surface plate along the longitudinal direction, and the frame member. When forming with a plurality of second frame members that are integrally provided on the face plate, at least one of the first frame members has a reinforcing side portion projecting on the indoor side, on the indoor side. Characterized in that it is formed of a projecting side portion projecting toward and a parallel side portion that is substantially parallel to the plate surface of the surface plate, and that each of these side portions is formed in a hollow follow mold. Is.

According to the present invention, the wind pressure strength from the indoor side can be increased to the same level as that of the outdoor side by this structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, 1 is an overhead type panel shutter (door), and the panel shutter 1
Is conventionally configured by using various member devices such as a shutter curtain 3 configured by connecting a plurality of panel materials 2 in a series and a guide rail 4 that guides the shutter curtain 3. Is.

The present invention is applied to the panel material 2. The panel material 2 has a long folded plate bent in a ridge and valley shape as a surface plate 5, and the surface plate 5 is provided above and below the surface plate 5. Upper and lower frames 6 and 7 that face the left-right lateral direction, five vertical frames 8 that vertically face the indoor side surface of the surface plate 5, and end members 9 at the left and right ends of the surface plate 5, respectively. It is integrally fixed. Here, the upper frame 6 is molded in a rectangular shape that is molded into a hollow follow mold, and the outdoor side surface 6a is formed.
The surface plate 5 is integrally fixed by rivets or the like, and the vertical frame 8 is integrally fixed to the indoor side surface so that it is integrally fixed to the upper edge of the panel member 2.

On the other hand, the lower frame 7 has a side portion 7 projecting from the frame body 7a, which is a hollow follow-type rectangular frame, toward the indoor side surface.
b is integrally projected, and the parallel side portion 7 is provided at the tip of the protruding side portion 7b and extends substantially parallel to the plate surface of the surface plate 5.
c is formed, and the projecting side portion 7b and the parallel side portion 7c form a reinforcing side portion. Both of the side portions 7b and 7c are hollow follow type. The lower frame 7 is integrally fixed to the lower end edge of the panel member 2 by integrally fixing the surface plate 5 to the outdoor side surface 7d of the frame body 7a by rivets and the vertical frame 8 to the indoor side surface. It is supposed to be done. The panel member 2 provided with the upper and lower frames 6 and 7 is connected in series by the hinge 10. The hinge 10 has a projecting side portion 7b whose upper end is integrally attached to the upper panel member 2. The lower end is fixed to the indoor side surface of the vertical frame 8 of the lower panel member 2, whereby the panel member 2 is foldably connected. The reinforcing side portion 3 is located at each connecting portion.

In the embodiment of the present invention constructed as described above, when the panel material 2 receives the wind pressure from the indoor side, the reinforcing side portion of the lower frame 7 receives the load in the direction of being compressed. In this case, the projecting side portion 7b and the parallel side portion 7c of the reinforcing side portion are hollow follow type members and receive a load. It is possible to reliably prevent the reinforcing side part from meandering or buckling, and it is possible to make it excellent in strength, and as a result, it is possible to reliably increase the strength against wind pressure from both inside and outside directions. .

Incidentally, two panels having a panel pitch of 500 mm and a panel length of 9050 mm are connected in series, and as shown in FIG. 7, the protruding amount X of the reinforcing side portion from the frame body 7a is 85 mm. All of the settings are made so that three follower frames 7 can be provided, and this is defined by the "deflection of slats" defined in 11.4 of Japanese Industrial Standard JIS A 4705 (fireproof shutter component). A strength test according to the method of “Test” was performed with the side from which the reinforcing side portion protrudes facing up. As a result, 210 kg / m ²
The panel began to deform when the load above was exceeded. On the other hand, the panel pitch is 500 mm and the panel length is 855
Two pieces with a length of 0 mm are consecutively provided, and as shown in FIG. 9, three frames with an inverted L-shaped reinforcing side portion in which the amount of protrusion X from the frame body is set to 85 mm are provided for convenience. Thus formed, the same strength test as described above was performed on this product with the side from which the reinforcing side portion protrudes facing up. As a result, the panel began to deform when the load of 77.5 kg / m ^{2 was} exceeded. From these results, the product of the present invention, which is 50 mm longer than the conventional product, has a strength increase of about 2.7 times, and it is possible to know how effective the present invention is. it can.

[0011]

In summary, since the present invention is constructed as described above, the panel member is reinforced by the protruding side portion protruding toward the indoor side and the parallel side portion parallel to the panel surface. Since the side part is projected toward the indoor side, when the wind pressure from the indoor side is received, the load due to the wind pressure will work in the direction of compressing the reinforcing side part, but in this case, Since the reinforcing side consisting of the side and the parallel side is formed in a hollow follow type, the reinforcing side can meander or buckle like a conventional one that is received by a single reinforcing side. As a result, it is possible to surely prevent the above-mentioned troubles and to be excellent in strength, and as a result, it is possible to surely increase the strength against wind pressure from both indoor and outdoor directions.
