Description

The present invention relates to the technical field of a guide rail structure in an architectural shutter device with a smoke prevention function that is installed at an opening such as a doorway of a building.

Today, architectural shutter devices are used to open and close openings such as entrances and exits of buildings and other structures by moving shutter curtains up and down on guide rails installed on both the left and right sides of the opening. Built-in construction is widely used. Generally, when such an architectural shutter device is installed at an opening of a large structure such as a building, the opening of the opening is large (wide) in both horizontal width and vertical height. A large and strong architectural shutter device (so-called heavy shutter device) will be provided.
For this reason, we fixed two strong (thick) L-shaped or 凵-shaped pieces together by welding them together, and also provided them in the rail groove at the outer edge of the shutter curtain in the left and right direction. A strong guide rail can be formed by welding a wind-resistant member with a wind-resistant receiving part that locks when the shutter curtain bends due to the wind and prevents the shutter curtain from coming off the guide rail. An attempt has been made (see Patent Document 1).

Incidentally, in this embodiment, the first groove side piece 3b side will be described as being on the outdoor side (outdoor side) and the second groove side piece 3c side will be described as being on the indoor side (indoor side), but the architectural shutter device 1 For example, as a winding method for the shutter curtain 2, there are two types: a forward winding specification in which the shutter curtain 2 is wound so that the interlock coupling part 2c faces toward the axis, and a reverse winding specification in which the shutter curtain 2 is wound so that it faces toward the outer diameter side. Generally, the first groove side piece 3b side is the indoor side, and the second groove side piece 3c side is the outdoor side.As for the definition of "indoors and outdoors" in the present invention, for example, the first groove side When focusing on the piece 3b, it is described as being able to be placed either indoors or outdoors.

The groove bottom piece 3a is provided in the opening E so as to be located on the outside in the left-right direction, and is formed in a flat plate shape with the same thickness (for example, 8 mm, 10 mm, etc.).
The first groove side piece 3b is a flat plate with a thick wall from the tip edge (inner edge) 3d, which is the inner edge in the left-right direction, to the groove bottom piece 3a. The corner portion 3e between the groove bottom piece portion 3a is thicker because the groove outer corner surface portion 3f has a small arc shape and the groove inner corner surface portion 3g has a large arc shape. It has a similar structure.

On the other hand, the second groove side piece 3c is disposed on the indoor side, and like the first groove side piece 3b, the tip edge (inner edge) 3h is the inner edge in the left-right direction. The area from the groove bottom piece 3a to the groove bottom piece 3a is formed into a thick flat plate shape, and the corner part 3i between the groove bottom piece 3a has a small (small diameter) circular arc shape with the groove outer corner surface 3j. The inner corner surface portion 3k has a large (large diameter) arc shape, resulting in a thicker structure.

In this embodiment, the first groove side piece 3b is shorter than the second groove side piece 3c, that is, the inner edge 3d of the first groove side piece 3b is shorter than the second groove side piece 3c. It is set to be located on the left-right direction outer side than the inner end edge 3h of the portion 3c, and at the left-right intermediate portion of the first groove side piece portion 3b (the left-right center portion of the second groove side piece portion 3c). In this case, a wind-resistant receiving piece 3l (corresponding to the "wind-resistant receiving part" of the present invention) protrudes toward the second groove side piece 3c, thereby connecting the guide groove X to the outer groove in the left-right direction of the groove. It is divided into two parts: a bottom half Xa and an inner opening half Xb.

The projecting portion of the wind-resistant receiving piece 3l from the first groove side piece 3b has a large-diameter arc shape, similar to the groove inner corner surface 3g, so that the groove inner corner on the groove bottom half Xa side A surface portion 3n and a groove inner corner portion 3o on the side of the groove opening half portion Xb are formed.

The guide rail 3 configured as described above includes a smoke-proofing material 6 having a pleated portion 6a so as to press against the front surface 2f of the curtain surface portion of the shutter curtain 2 to exert a smoke-proofing function, The mounting bracket 7 for attaching the material 6 to the guide rail 3, the first and second decorative plates 8 and 9 provided on the first and second groove bottom pieces 3b and 3c, and the guide rail 3 are attached to the frame side members. A guide rail assembly equipped with a connecting member 11 for attaching to a certain support 10 and a hanging fitting 12 for hoisting the guide rail 3 on-site and installing it on the frame is assembled at a factory as a guide rail assembly and shipped to the site. However, the smoke prevention material 6, its mounting fittings 7, first and second decorative panels 8 and 9, and the connecting member 11 will be specifically explained below. Note that the hanging fittings 12 may be attached and detached at the site.

The smoke-proofing material 6 is made of a rubbery elastic material, and has a pleated part 6a extending from a main body part 6b, which is flexible to be elastically deformed, and the main body part 6b has: It is fitted and assembled into a groove-shaped main body attachment portion 7a formed on the attachment fitting 7. The mounting bracket 7 is integrated with the first groove side piece 3b by fixing (welding) the square-shaped support part 7b to the inner edge 3d of the first groove side piece 3b. , and the main body attachment part 7a is provided so as to be biased toward the second groove side piece part 3c with respect to the support part 7b. In the space formed by the L-shaped groove inner surface formed by the first groove side piece 3b (more precisely, the extension part of the first groove side piece) and the wind-resistant piece 3l, the first groove With respect to the side piece 3b, it is biased toward the second groove side piece 3c (with a gap), and with respect to the wind-resistant receiving piece 3l, it is biased inward in the left-right direction (with a gap) The smoke prevention material 6 has a pleated portion 6a projecting in an inclined manner from the fitting groove portion 7a toward the windproof receiving piece portion 3l and the second groove side piece portion 3c side, and the smoke prevention material 6 has a folded portion 6a projecting from the fitting groove portion 7a toward the windproof receiving piece portion 3l and the second groove side piece portion 3c side. It comes into contact with the surface portion 2e (front surface 2f) in an elastic manner, thereby providing a smoke prevention function between the shutter curtain 2 and the guide rail 3.

As described above, the guide rail 3 is attached and fixed to the support column 10, and in this case, connecting members 11 are provided as auxiliary members with gaps in the vertical direction (in a scattered state). In this embodiment, the connecting member 11 is made of an L-shaped member, and the vertical piece 11a is fixed (welded) to the groove outer side surface 3q of the first groove side piece 3b. It is provided with an extending portion 11b that extends beyond the inner end edge 3d of the first groove side piece and extends inward in the left-right direction, and the supporting portion 7b of the mounting bracket 7 is fixed to the vertical piece portion 11a of the extending portion 11b ( By welding), the fitting 7 is reinforced and supported by the connecting member 11.
The mounting bracket 7 configured in this manner is set so that the inner edge 3h of the second groove side piece 3c and the inner edge 7c in the left-right direction are at the same position in the left-right direction, and the mounting bracket 7 and The outer surface (surface) of the second groove side piece 3c is covered with first and second decorative plates 8 and 9.
In this case, the first decorative board 8 is also used as a part of the mounting fitting 7, with the groove inner piece 8a abutting and supporting the groove inner surface of the smokeproof material main body 6b. The surface piece 8b bent from the inner groove piece 8a extends beyond the support part 7b that overlaps the main body attachment part 7a and the second groove side piece 3b of the fitting 7, and reaches the connecting member 11. The mounting surface part 8c bent from the surface piece part 8b is attached to the supporting metal fitting 11d provided on the outer edge of the upper piece part 11c of the connecting member 11 in the indoor/outdoor direction by screws or adhesive. It is fixed via a fixing member such as adhesive or double-sided adhesive tape.

The second decorative board 9 covers the surface of the second groove side piece 3c, but in this embodiment, it covers the inner surface of the groove opening side half Xb of the second groove side piece 3c. Fixing screws, adhesives, double-sided adhesive tape, etc. to the groove inner surface 9a to be covered, the surface piece 9b covering the inner edge 3h, and the support fittings 9c provided on the groove outer surface of the second groove side piece 3c. It is configured to include a mounting surface portion 9d that is fixed via a member.
In this case, the first and second decorative bodies 8 and 9 are set so that the surface pieces 8b and 9b are flush with each other.

The guide rail 3 configured in this way will be attached to the support post 10 at the site. In this case, if the support support 10 is a square-shaped member, as shown in FIG. The support column 10 is further fixed (welded) via an auxiliary fitting 13, and the groove bottom piece 3a and the column 10 are fixed via an L-shaped connecting fitting 14.
In this way, when the support 10 is placed further outward in the left-right direction than in the case of FIG. 8, the structure for attaching the support to the support 10 may be formed in an L-shape as shown in FIG. Accordingly, the connecting fitting 11 and the auxiliary fitting 13 on the support column 10 side can be connected and fixed via the extension fitting 15 having a desired shape.
Further, when the support column 10 is made of H-beam steel, as shown in FIG. In this case, the auxiliary metal fitting 13 can be fixed to the web 10a on the side closer to the guide rail 3, or fixed to the web 10b on the far side. Needless to say.

Furthermore, when the shutter curtain 2 is subjected to a large wind pressure, it will bend toward the indoor/outdoor direction, but if this wind pressure is directed toward the indoor side, that is, it is a positive pressure, the shutter curtain 2 will bend in the direction shown in FIG. As shown in (A), the central part side in the left-right direction bends toward the indoor side, and in this case, the shutter curtain 2 has a back surface (indoor side surface of the curtain surface part 2e) 2h that is connected to the second groove side piece part 2c. At the same time, the windproof hook 2b comes into contact with the groove inner corner part of the inner edge part 3h of the second decorative board 9 (specifically, the corner part 9e of the second decorative board 9), and the windproof hook 2b contacts the groove bottom side half of the inner edge part 3m of the windproof receiving piece. The state where the portion Xa side is locked to the corner portion 3p is the maximum bent state. In this state, the mounting bracket 7 arranged on the outdoor side is spaced apart from the shutter curtain 2 and is not affected by the deflection of the shutter curtain 2.
On the other hand, as shown in FIG. 7(B), when the shutter curtain 2 receives wind pressure directed toward the outdoors, that is, negative wind pressure, the central portion of the shutter curtain 2 in the left-right direction bends toward the outdoors. In this case, in the shutter curtain 2, the outdoor side edge 2g of the outer edge in the left and right direction is connected to the groove inner surface of the second groove side piece 2c (in the present embodiment, the groove inner surface 9a of the second decorative board 9). The state in which the windproof hook 2b is engaged with the Xa side corner part 3p of the groove bottom half of the inner edge 3m of the windproof receiving piece is in the maximum deflection state. In this state, the mounting bracket 7 placed on the outdoor side is placed on the side close to the deflected shutter curtain 2, but in this embodiment, it is not possible to receive such negative pressure. When the shutter curtain 2 is bent to the maximum extent outdoors, the mounting bracket 7 is positioned so that the corner portion 8d is either separated from the shutter curtain 2 or comes into contact with it. The mounting bracket 7 is designed to be protected when the mounting bracket 7 is bent due to wind pressure.
Incidentally, the mounting bracket 7 of the present embodiment has a reinforced structure in which a plurality of metal plates including the first decorative board 8 are laminated. As a result of being supported by a connecting fitting 11 provided to connect the guide rail 3 to the pillar 10, it is strongly reinforced so that it will not easily deform even if the deflected shutter curtain 2 comes into contact with it. The shutter curtain 2 is designed so that it can maintain its shape with considerable strength when the deflected shutter curtain 2 is subjected to a load when they come into contact with each other. The solder shutter curtain 2 may be configured to abut against the mounting fittings 7.

In this embodiment configured as described above, the guide rail 3 is a molded member integrally formed by extrusion molding a steel material, and includes a groove bottom piece 3a on the outer side in the left and right direction, and a right and left side from the groove bottom piece 3a. It has a concave groove shape with first and second groove side pieces 3b, 3c on the indoor and outdoor sides extending inward in the direction, and constitutes a guide groove X, and also on the first groove side. The piece 3b is configured to include a wind-resistant receiving piece 3l that protrudes toward the second groove-side piece 3c, and the wind-resistant receiving piece 3l prevents the shutter curtain from being bent by the wind. When the shutter curtain 2 is installed, the windproof hooks 2b provided on the shutter curtain 2 are locked to prevent the shutter curtain 2 from coming off the guide rail. The smoke prevention material 6 for preventing smoke by contacting the curtain surface 2e of the shutter curtain 2 is attached to the first groove side piece through the mounting fitting 7 while being located inside the windproof receiving piece 3l in the left and right direction. It will be attached to 3b.
As a result, the guide rail 3 itself can be made strong by integrally forming the groove bottom piece 3a, the first and second groove side pieces 3b and 3c, and the wind-resistant receiving piece 3l by extrusion molding of steel material. However, the smoke-proofing material 6 is attached via the mounting bracket 7 to the left-right direction inner side of the wind-resistant receiving piece 3l of the first groove side piece 3b, so that the installation space for the smoke-proofing material 6 is saved. This can be easily secured to the guide rail 3, resulting in an architectural shutter device with excellent smoke prevention properties.

Moreover, in this case, since the smoke prevention material 6 is provided so as to be biased inward in the left-right direction from the inner edge 3d of the first groove side piece 3b, The smoke prevention material 6 can be installed by effectively utilizing the space on the inside (on the front side), which makes it possible to avoid complicating the structure and also facilitates the installation of the smoke prevention material 6.
Moreover, since the smoke prevention material 6 is provided so as to be biased toward the second groove side piece 3c with respect to the groove inner surface of the first groove side piece 3b, Since the installation can be performed using space effectively, the installation structure can be simplified and the workability of the installation work can be further improved.

Moreover, the mounting fittings 7 for attaching the smoke prevention material 6 to the first groove side piece 3b are positioned at approximately the same position in the left and right direction as the inner edge 3h in the left and right direction of the second groove side piece 3c. Therefore, although the guide rail 3 is provided with the smoke prevention material 6, the indoor and outdoor opening edges of the guide groove Since the opening edges can be made uniform on the inside and outside surfaces, the guide rail 3 can be made with excellent appearance and uniformity.

Moreover, the first groove side piece 3b is formed with the wind resistant receiving piece 3l at an intermediate position in the left-right direction, so that the first groove side piece 3b is more horizontally An L-shaped groove inner surface is formed in a plan view by the inner surface and the smoke preventive material 6 is provided on the groove inner surface. This means that it can be attached while being protected by the groove side piece 3b.
Moreover, in this case, the first groove side piece 3b is set to be short so that the inner end edge 3d in the left-right direction is located further back in the groove than the second groove side piece 3c. As described above, the mounting bracket 7 can be positioned at the same position as the inner edge 3h of the second groove side piece 3c while the tip side portion of the edge 3d is used as a space for disposing the smoke prevention material 6. Become.
In addition, the smoke prevention material 6 is attached to the mounting bracket 7 with a gap between the first groove side piece 3b and the second groove side surface portion 3c, so the smoke prevention material 6 has elasticity to fill the gap. Since the space can be secured for deformation, installation can be easily performed without compromising the smoke prevention function.

In this way, the mounting bracket 7 to which the smoke prevention material 6 is attached is in contact with the deflected shutter curtain 3 until the deflected shutter curtain 3 reaches its maximum deflection position where it is prevented from coming off due to wind pressure.
