Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In general, a reinforcement structure of a panel of this type includes a structure in which a frame material is framed on the back surface (indoor side surface) of a surface material made of a steel plate or the like. In addition, the strength is required to withstand a certain negative pressure (a pressure that is pulled in the outdoor direction as a reaction when the panel receives external pressure due to wind pressure or the like from the outside of the building). For this reason, the applicant of the present invention disclosed in Japanese Unexamined Patent Publication No.
No. 93142, at least one of the upper and lower frames constituting the panel is a projecting side 7b projecting perpendicularly to the surface material toward the indoor side, and the front surface of the panel is provided at the tip of the projecting side 7b. A panel reinforcement structure for a panel shutter in which a parallel side portion 7c extending in a state substantially parallel to the material is formed into an integral structure, and both the protruding side portion 7b and the parallel side portion 7c are formed in a hollow follow shape. (Hereinafter, this invention is referred to as “prior art”).

[0003] Such a panel reinforcement structure according to the prior art,
The counter pressure strength of the negative pressure is higher than that of the reinforcement structure of the same type using the solid material before that, and the operation effect has been verified by simulation experiments and the like.

However, for the lower frame, for example, the main part of such reinforcement is a hollow follow-type protruding side 7b.
Even if it is an integrated structure related to the combination with the parallel side portion 7c, most of the effect of reinforcing the pressure resistance against the negative pressure depends on the protruding side portion 7b. That is, the protruding side portion 7b
It has been found from the subsequent improvement experiments of the prior art that the reinforcing shared stress of the parallel side portion 7c to the negative pressure is smaller than that of the protruding side portion 7b among the combined stress of the parallel side portion 7c. In particular, when the protrusion size of the reinforcement structure on the indoor side is limited by setting conditions such as securing the maximum indoor space area,
The larger the size of the parallel side portion 7c, the more the size of the projecting side portion 7b toward the indoor side is limited, and the maximum moment of area of the reinforcing material in the direction perpendicular to the surface material 5 can be maximized. It can be difficult. This is because the center of gravity of the lower frame 7 moves toward the parallel side 7c as the size of the parallel side 7c increases. On the other hand, the parallel side 7c
Functionally, the pressure resistance in the vertical direction of the panel 2 is large,
Further, after the buckling of the protruding side portion 7b starts to occur, the function of reducing the meandering deformation phenomenon of the protruding side portion 7b as much as possible is considered to be large. Therefore, in designing the reinforcing structure, the bending of the panel 2 is reduced. It is necessary to examine how to increase the value of the second moment of area in the vertical direction. In addition, although the above-mentioned reinforcing structure is usually made of an aluminum mold material integrally formed with the frame member, in the prior art, a projecting side portion 7b is provided on the frame member, and a follow-type parallel side portion 7
Since the structure is such that c is integrally molded, there may be difficulties in molding. That is, in the reinforcement shape of the prior art, the follow-type parallel side portion 7c is located at a position considerably eccentric from the center of the extrusion die, so that the billet is easily twisted in the extrusion when the billet is extruded. Meters in some cases), a high degree of extrusion technology was required, and there was a drawback in terms of so-called yield.

[0005]

In order to overcome such a problem as quickly as possible, the present invention relies exclusively on the protruding side portion 7b as a pressure-resistant effect of the reinforcing member against a negative pressure. Focusing on the point that it is advantageous to make the protrusion dimension of the protruding side part 7b as large as possible by making the parallel side part 7c thin in order to increase the value of the second moment of area in the vertical direction, An object of the present invention is to provide a reinforcing member that can obtain a desired reinforcing effect by adopting a simpler shape for the parallel side portion 7c as compared with the technology. However, the reinforcement effect against negative pressure is also inextricably related to the reinforcement effect against positive (external) pressure,
The reinforcing effect against the negative pressure inevitably also enhances the reinforcing effect against the external pressure.

[0006]

For this purpose, a reinforcing structure for dealing with negative pressure of a panel according to the present invention comprises a panel material for a panel shutter, a long surface material and a longitudinal direction. In forming with a plurality of long side stile materials provided integrally along, and a plurality of vertical stile materials provided integrally with the surface material in a state perpendicular to the side stile material, At least one of the horizontal frame members is formed integrally with only the frame main body and only a hollow protruding side portion protruding substantially vertically toward the room side with respect to the panel material. By doing so, a desired buckling effect against negative pressure can be obtained while having an extremely simple shape, and a linearly extrudable reinforcing material with little distortion such as twisting in the longitudinal direction can be obtained. . Further, in the present invention, at least one of the side edges on the side of the horizontal frame of the reinforcing side extends from one of the upper and lower ends of the indoor side found side of the horizontal frame. Therefore, it is possible to improve the reduction of the bending of the panel in both the horizontal and vertical directions with respect to the reinforcing side. Furthermore, in these inventions, the indoor end of the protruding side is made thicker than the other protruding sides. By doing so, the centroid of the frame is hardly moved in the thickness direction, so that the quadratic coefficient value of the cross section of the reinforcing side in the direction perpendicular to the panel can be increased, and the negative pressure can be further reduced. It can be a durable reinforcing material. In addition, a panel material for a panel shutter is formed of a long surface material, a plurality of long horizontal frame members integrally provided on the surface material along the longitudinal direction, and orthogonal to the horizontal frame material. In forming a plurality of vertical frame members integrally provided on the surface material in a state, at least one of the horizontal frame materials is substantially perpendicular to the indoor side with respect to the frame body and the surface material. A hollow protruding side portion protruding in the direction, which has a solid parallel side portion substantially parallel to the surface material at the tip of the protruding side portion, is formed integrally. By doing so, it is possible to minimize the meandering deformation of the protruding sides of the solid parallel sides, and to minimize the twisting during extrusion molding even for long reinforcing frames. can do. Further, in the present invention, since the solid parallel side portion can have a structure in which another reinforcing member can be further extended on the indoor side of the protruding side portion, the surface material can be stepwise and interchangeably. The reinforcing means can secure a second moment of area in the vertical direction.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a panel shutter of an over-slider type.

It is configured to be fixedly attached. The upper frame 6 does not have a protruding side portion, and the expected thickness portion has stepped sides 62a, 63a, 6a.
4a, the outdoor side found side 65a is hung down from the outer end of the side 64a so that the upper end of the surface material 5 can be fitted thereto, while the indoor side found side 61a is hung down from the indoor side of the side 62a and from the lower end thereof. It is formed with a bent side 60a facing the outdoor side. Thus, the outdoor side finding side 65
a, the upper end of the surface material 5 is fitted and fixed to the inner surface a, and the vertical stile 8 is integrally fixed to the indoor surface side by bolting or the like, so that the vertical frame 8 is attached to the upper end of the panel material 2. Have been.

On the other hand, the lower frame 7 comprises a lower frame main body 7a and a protruding side 7
This is a mold material integrally formed with only b. Here, the lower frame main body 7a has an estimated thickness portion corresponding to the upper frame 6 directly below the panel 2 so as to engage with the upper frame 6 by the sides 72a and 73.
a and 74a, the outdoor side found side 75a is raised from the side 74a so that the lower end of the surface material 5 can be fitted thereto, and the indoor side found side 71a is raised from the indoor side of the side 72a and from the upper end thereof. It has a bent side 70a directed toward the outdoor side. Further, a protruding side portion 7b is formed integrally from the lower frame main body 7a toward the indoor side surface only in a direction substantially perpendicular to the panel material 2 with the indoor side found side 71a as a bottom portion. Side 7b is side 7
It has a hollow follow type having 0b and a side 71b as main constituent sides. The lower frame 7 is integrally fixed to the outdoor side surface 75a of the lower frame main body 7a so that the surface plate 5 can be fitted thereinto.
The vertical frame 8 is integrally fixed to the indoor side edge 71a with bolts or the like, so as to be attached to the lower edge of the panel material 2.

As described above, the basic reinforcing structure of the panel member 2 of the panel shutter 1 is such that only the protruding side 7b is provided on the lower frame 7 as seen from the arrow X, and the upper frame 6 has no protruding side. Only the upper frame main body 6a is provided, but the uppermost panel 2 is provided with a protruding side portion 7b on the lower frame 7 as viewed from the arrow Y and the upper frame 6
Also provided is an upper frame main body 6a integrally formed with a protruding side 6b. Therefore, the panel materials 2, 2,
.. Has a protruding side 7b only on the lower frame 7 of each panel except for the uppermost part.

Next, the protruding side b according to the second aspect of the present invention will be described with reference to FIG. In the embodiment of the present invention, the base end 70b of the projecting side 7b (6b) on the side of the frame body 7a (6a) is provided.
(60b) and 71b (61b) are connected to the frame body 7a (6
This is located at the upper and lower ends of the indoor-side finding surface 71a (61a) of a). By doing so, it is possible to increase the combined stress with respect to the twist of the entire frame,
The warpage of the panel 2 can be reduced, and the rigidity of the panel 2 itself can be increased. Further, for example, by providing a rib in the protruding side portion 6b, it is possible to further increase the stress. As shown in FIGS. 6A and 6B, such a reinforcing structure may be provided only on the lower frame 7 or on both the upper and lower frames. Alternatively, only one side (70b) of the side base end may be made to face indoors from the end of the indoor side finding surface (71a).

Further, FIG. 7 shows an embodiment of the projecting side portion according to the third aspect of the present invention. Each of them relates to the lower frame 7, but in FIG. 7 (A), the wall pressure t at the tip on the indoor side in FIG. 4 (B) is made thicker than the sides 70b and 71b. Thereby, the cross section in the vertical direction to the surface material 5
Since the second moment can be increased, the negative pressure strength can be improved, and the torsional rigidity of the surface member 5 in the horizontal direction can be increased. FIG.
(B) shows the base end portions 70b, 71b on the indoor side finding surface 71.
Since the wall thickness t of the trapezoidal indoor side tip is made thicker than the other side, the same function and effect can be obtained. In addition, FIG.
And vertical and horizontal ribs 701b, 702b
Is provided, a further withstand voltage effect can be obtained. In this case, if the above ribs are used in particular by increasing the wall pressure at the indoor end portion in FIG. 7 (B) from the other side, the wall pressure t can be increased without increasing the wall pressure t from the other side. The second moment of area in both the vertical and horizontal directions can be increased.

Next, the invention according to claim 4 will be described. The corresponding reinforcement structure is shown in FIG. 8A for the upper frame and FIG. 8B for the lower frame. For example, in the case of a lower frame, these reinforcing structures are arranged so that the horizontal side 7c is
b, which are hung down at the tip of b.
The thickness of c is substantially the same as the thickness of the constituent side of the protruding side 7b. As a result, in the extrusion molding of the mold material, the occurrence of warpage and twisting can be reduced due to the presence of the horizontal side portion 7c as in the related art. Therefore, the yield as a frame member is also improved. Further, the protruding side portion 7b is of a follow type, so that the protrusion dimension of the protruding side portion 7b toward the indoor side can be obtained to a maximum as compared with FIG. For this reason, the second moment of area in the direction perpendicular to the surface material 5 can also maintain a substantially maximum value, so that it is most effective in suppressing the bending of the panel 2 against a negative pressure or a positive pressure in this direction. be able to.

Next, the invention according to claim 5 will be described. The corresponding reinforcement structure is shown in FIGS. 9A and 9B.
(C) and (D). Here, the lower frame 7 in FIG. 9C will be described. The horizontal side portion 7c is hung at the tip of the protruding side portion 7b as a slightly thick solid body. The thickness of 7c is greater than the thickness of the constituent side of the protruding side 7b. However, the horizontal side portion 7c also functions as a fitting side when a protruding side portion 7d is desired to be provided on the indoor side (FIG. 9D). As a result, if several types of reinforcing side portions 7d are prepared as options,
It is possible to flexibly provide a reinforced panel 2 adapted to natural environmental conditions (particularly a hill which receives strong wind pressure) at the site where the panel shutter 1 is attached.

The panel 2 provided with the upper and lower stiles 6 and 7 as described above is continuously bound in a series by the hinge 10, and the hinge 10 has an upper panel material at the upper end as viewed in the direction of arrow Z in FIG. 2 is fixed to the lower surface of the reinforcing side portion 7b, and the lower end portion is fixed to the indoor side surface of the vertical frame 8 of the lower panel member 2, whereby the panel members 2 and 2 are connected in a freely bendable manner. In the shutter curtain 1, the protruding side portion 7b is arranged at each continuous binding portion. In addition, it is a matter of course that the surface material 5 and each frame are firmly riveted.

In the embodiment of the present invention configured as described above, when the panel material 2 receives a negative pressure, the protruding side portion 7b
Receives a pressing load that is compressed in the longitudinal direction, which is the width direction of the panel. In this case, the second moment of area or the section modulus can be made equal to or more than that of the synthetic reinforcing member of the prior art by the thickness of each portion of the protruding side portion 7b or the like. The above strength can be obtained, and the meandering of the protruding side portion 7b can be reduced as much as possible. Also like this,
It is possible to surely increase the strength not only under a negative pressure but also under a positive pressure load from the outdoor side.

In short, since the present invention is constructed as described above, only one or both of the upper and lower frames are integrally formed on the frame body with only a protruding side perpendicular to the surface material, or Although it is a side part, by changing the specification from follow type to solid flat side, reinforcement of the panel can be secured by reducing the bending of the panel against negative pressure equal to or greater than the conventional technology, and at the same time The pressure resistance can be ensured even with a positive pressure load.
