Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rising ALC wall structure with a handrail, and in particular, a hand that can be firmly attached to a handrail on a veranda, corridor, staircase, balcony, parapet or the like composed of an ALC panel (hereinafter simply referred to as a panel). The present invention relates to a rising ALC wall structure with sliding.
[0002]
[Prior art]
Conventionally, a structure as shown in FIG. 5 is known as a rising ALC wall structure with handrails such as a corridor, a staircase or a balcony, a veranda, and a parapet. That is, the panel is composed of an L-shaped receiving angle 91 for receiving the lower fore edge 90 of the ALC panel P, an L-shaped supporting angle 92 for supporting the upper portion of the panel P, and an L-shaped angle 93 on the side of the panel connecting them. P is supported. Further, a countersink hole and a bolt hole (not shown) are machined near the upper part and the lower part of the panel P, and the hook bolt 94 is fixed with the washer and the hook bolt 94 mounted in these holes. 94 is welded and fixed to the lower L-shaped receiving angle 91 and the upper L-shaped support angle 92 to fix the panel P.
[0003]
A pillar 95 of a handrail H is fixed to the upper surface of an L-shaped support angle 92 that supports the upper portion of the panel P by welding, bolting, or the like. In this structure, the upper and lower ends of the ALC wall are supported by L-shaped angles, and the handrail pillar is directly fixed to the upper L-shaped support angle, so that the force applied to the handrail H is applied to the panel. It is a structure not applied to P.
[0004]
[Problems to be solved by the invention]
However, in the conventional rising ALC wall structure with a handrail as described above, not only must an L-shaped angle be provided on both sides and top of the ALC wall panel, but an upper L-shaped receiving angle and hook bolt Etc. are not preferable in appearance because they stand up and protrude inside the ALC wall panel. In order to solve this problem, it was necessary to stick a molding board or the like on the back surface of the panel to cover the L-shaped angles on both sides of the panel. For this reason, there are problems that the number of members for supporting the panel is further increased, the cost is increased, and the mounting work is troublesome. On the other hand, if these L-shaped angles are eliminated, there is a problem that the handrail cannot be fixed or difficult.
[0005]
Accordingly, an object of the present invention is to eliminate the conventional problems using the L-shaped angles as described above, and at the same time, to provide a rising ALC wall structure with a handrail capable of firmly attaching a handrail on the ALC wall. It is to provide.
[0006]
[Means for Solving the Problems]
In order to solve the problems as described above, the present invention has the following configuration.
In a rising ALC wall structure with a handrail, a handrail is provided on the upper edge of the ALC wall such as a veranda, balcony, parapet, corridor, stairs, etc. composed of a plurality of ALC panels.
The ALC panel is attached to the building frame via an anchor portion embedded in the center portion in the width direction and at two locations of the lower portion and the middle portion of the panel and a panel mounting bracket that engages with the anchor portion.
A T-shaped bracket consisting of a plate and a rod-like body fixed perpendicularly to the back surface of the ALC wall is located at least near each end on the upper fore-edge surface of the ALC wall. Inserted into the hole, and the tip of the rod-shaped body is fixed by being inserted into the embedded position of the reinforcing bar embedded in the ALC panel,
Further, a steel plate is laid and fixed on the upper edge surface by welding on the plate of the T-shaped metal fitting, and a handrail is fixed on the steel plate.
[0007]
The effects of the present invention will be described below.
In the present invention, the panel is attached to the housing at the center in the width direction at two locations, the lower part and the middle part, and the steel plate is laid and fixed on the upper edge of the panel via a T-shaped bracket. Combined with the structure, sufficient mounting strength can be obtained. Also, it is no longer necessary to provide L-shaped receiving angles on both sides and top of the ALC wall panel. As a result, a molding board or the like is attached to the back of the ALC wall panel to cover the L-shaped angles on both sides of the panel. There is no need to do.
[0008]
Therefore, since it can be attached with fewer supporting members, the cost is reduced and the attaching operation is also reduced. Further, since the steel material such as the upper L-shaped receiving angle does not protrude to the inside of the rising ALC wall panel, the appearance is not impaired.
[0009]
According to the basic structure of the present invention, various functions and effects as described above can be obtained, but on the other hand, since there is no steel material such as an upper L-shaped angle, a handrail is formed on the upper edge of the ALC wall. It becomes difficult to attach. Therefore, in the present invention, a steel plate is laid and fixed on the upper edge surface of the panel via a T-shaped bracket composed of a plate and a rod-like body fixed to the back surface thereof.
[0010]
However, the ALC panel has a problem that the strength is small as compared with other concrete materials, and the end portion is particularly easily chipped. Therefore, it is difficult to fix the steel plate at each end portion on the upper edge surface of the ALC wall, and the steel plate at each edge portion tends to be lifted from the edge surface. Therefore, in the present invention, in order to securely fix the steel plate near each end, a hole is inserted in the upper fore edge surface and a rod-shaped body is inserted, and the position where the reinforcing bar is embedded in the panel is embedded. It was set as the structure inserted even inside. That is, since the ALC panel in this region has a high strength, the T-shaped bracket is more firmly fixed.
With the above configuration, the handrail is firmly attached on the upper edge of the ALC wall, and the handrail is provided on the upper edge of the ALC wall, so that the load applied to the handrail is supported by the entire ALC wall. And the panel is not overloaded.
[0011]
Further, in the present invention, a protrusion is formed at a predetermined position between the central portion of the rod-shaped body of the T-shaped bracket and the plate, and the protrusion is bitten into the inner peripheral surface of the hole. More preferred. That is, by doing this, it is possible to prevent rattling of the rod-like body inserted inside the hole, and the protrusion is bitten into the inner peripheral surface of the hole, so that it is firmly supported by the inner surface of the hole, As a result, the steel plate is firmly fixed to the T-shaped metal fitting without loosening. If the protrusion is provided below the central part of the rod-shaped body, the T-shaped bracket rattles, the hole entrance is gradually destroyed, and cracks occur and the end of the ALC panel is easily chipped. Finally, the T-shaped bracket near the end is easily removed.
[0012]
Furthermore, a countersink is provided at the entrance of the hole, and the plate of the T-shaped bracket is positioned so that the surface thereof is substantially flush with the upper edge surface, and the side wall of the countersink and the outer periphery of the plate It is desirable that a gap be formed between the surface. In other words, due to the presence of the gap, even if the plate is displaced due to an earthquake or a large load, the outer peripheral surface does not strongly press the side wall of the countersink portion, so that the side wall of the countersink portion is not destroyed. Since the end of the ALC wall is easily chipped, the side wall is destroyed even if the T-shaped metal plate provided near the end is slightly displaced, and if it is greatly displaced, cracks are likely to occur around it. . Accordingly, such a gap is more preferable when the T-shaped bracket is fixed near the end of the ALC wall.
[0013]
Furthermore, the rod-shaped body of the T-shaped metal fitting is inserted into a hole opened on the top edge of the upper edge of the ALC wall, and the tip of the rod-shaped body is located at the middle position on the edge of the upper edge of the ALC wall. It is desirable that the T-shaped bracket is fixed by being inserted up to the embedded position of the reinforcing bar embedded in the ALC panel, and the steel plate is laid and fixed on the plate by welding. In this way, the fixing strength can be improved by providing a predetermined number of intermediate positions on the upper edge of the ALC wall according to the length of the ALC wall and increasing the number of fixing positions of the steel plate. . Further, at that time, the joint portion embedded member may be embedded by mortar in the joint portion formed by abutting the side edge surfaces of the panel to each other, and the steel plate may be fixed to the upper end portion thereof. . In this case, since it is not necessary to make a hole or the like in the panel for the portion where the joint portion embedding member is used, the work can be omitted. On the other hand, the fixing with the T-shaped metal fitting does not require the use of mortar for the joint, and is suitable for the dry method.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, a plurality of panels 2 are abutted against each other by the side edge surfaces 2 a to form a rising ALC wall 1. The panel 2 used for them is preferably a panel having a height of 500 to 2000 mm, a width of 300 to 600 mm, and a thickness of about 80 to 150 mm.
[0015]
Each panel 2 includes an anchor portion 4 embedded at two positions, that is, near the lower portion of the panel 2 and a middle portion in the vertical direction and at the center position in the horizontal width direction of the panel, and a panel mounting bracket 5 that engages with them. It is attached to a building frame 6 composed of a beam 6a, an L-shaped angle 6b, and the like via bolts.
[0016]
The position of the anchor part 4 at the middle part of the panel is separated from the anchor part 4 at the lower part of the panel by 300 mm or more. In addition, it is desirable that the distance from the position to the upper fore edge surface 1a which is not directly connected to the housing 6 but is a free end is 1500 mm or less at the maximum. Further, a floor panel or the like (not shown) is laid on the upper surface of the beam 6a of the building housing 6 to which the rising ALC wall 1 is attached in this manner.
The anchor portion 4 embedded in the panel 2 is composed of a long L-shaped steel 4a having a length 3/5 of the horizontal width of the panel 2 and a single anchor nut 4b fixed to the center portion thereof. Yes. The length of the anchor portion 4 is desirably 1/3 or more of the lateral width of the panel 2 from the viewpoint of yield strength.
[0017]
The panel mounting bracket 5 has the following configuration, and is fixed to the standing piece 6ba of the L-shaped angle 6b.
That is, a mounting plate 5a provided with a bolt insertion portion, a protruding piece 5b formed by extending the upper portion thereof, a rib piece 5c formed by bending both side edges of the mounting plate 5a, and a rib thereof The piece 5c is composed of a hanging rib piece 5d that is formed to hang downward. Further, the thickness of the mounting plate 5a is substantially equal to the thickness of the L-shaped angle 6b, and the rib piece 5c is formed by bending both side edges of the mounting plate 5a, and the hanging rib piece 5d hangs downward from the rib piece 5c. Therefore, it has a level | step difference by the thickness of the board rather than the surface of the panel attachment board 5a. Therefore, if the step is engaged with the standing piece portion 6ba of the L-shaped angle 6b and the portion is welded and fixed, the surface of the mounting plate 5a and the standing piece portion 6ba are almost flush with each other, and the panel is applied thereto. There will be no steps or gaps.
[0018]
Further, the panel mounting bracket 5 has a plate-like body with a wide surface for pushing the panel 2 by the projecting piece 5b, and the projecting piece 5b is not provided with rib pieces 5c on both side edges. Since the panel 2 is pushed while being bent, the panel mounting plate 5a can be supported without being recessed into the panel. As a result, the proof stress against the pressing force of the panel can be improved.
[0019]
Next, the attachment of the T-shaped bracket 7 and the laying / fixing structure of the steel plate 10 for providing the handrail 3 on the upper edge surface 1a of the rising ALC wall 1 formed as described above will be described. First, the mounting structure of the T-shaped bracket 7 is as follows.
Holes 8 are formed at positions near the ends 1b on the upper fore edge face 1a of the rising ALC wall 1 and at other intermediate positions, as shown in FIG. A T-shaped metal fitting 7 composed of a vertically fixed rod-like body 7 b is fixed by inserting the rod-like body 7 b into the hole 8. Further, the rod-like body 7b is inserted to the inside of the position where the reinforcing bar 9 embedded in the panel 2 is embedded, that is, to the region surrounded by the reinforcing bar 9 embedded in the panel 2. .
[0020]
In the present invention, the rod-like body 7b of the T-shaped metal fitting 7 preferably has a protrusion 7c formed at a predetermined position from the center to the plate 7a as shown in FIGS. That is, the protrusion 7c is bitten into the inner peripheral surface of the hole 8 and provided between the center portion and the plate 7a, so that the rattling of the rod-like body 7b inserted into the hole 8 is added to the plate 7a. The T-shaped bracket 7 can be held by the panel 2 more firmly.
If the protrusion 7c of the rod-like body 7b is located below the center, that is, on the tip side, rattling occurs between the protrusion 7c on the tip side and the plate 7a, and it cannot be firmly fixed. . In addition, the entire T-shaped metal fitting 7 comes to rattle near the entrance 8a of the hole 8, and as a result, the panel near the entrance 8a is gradually destroyed.
[0021]
It should be noted that it is desirable that the protrusion 7c has a height of 1 to 5 mm and a length of about 2 to 6 mm to be protruded from two to several in terms of ensuring the fixing. More preferably, it is provided in a portion of the rod-like body 7b at a distance of 5 mm or more from the plate 7a so as not to break the vicinity of the inlet 8a. Further, a plurality of protrusions 7c in series may be provided, or a protrusion 7c continuous from the central position to the near chamber of the plate 7a may be provided.
The protrusion 7c can be easily formed by picking out the side surface of the rod-like body 7b with a press or the like. Further, in order to more securely fix the T-shaped bracket 7, a synthetic resin adhesive such as a low-viscosity urethane or epoxy resin may be injected into the hole 8 and solidified.
[0022]
In addition, as shown in FIG. 1, the ALC panel P used for the rising wall is formed by welding a reinforcing bar in a grid shape and bending it into a C shape, or welding the reinforcing bar in a grid shape. The two reinforcing mats 9 are connected to each other in the form of a mat and are present inside as reinforcing bars 9. In the present invention, as described above, the tip of the rod-like body 7b needs to be inserted up to the region surrounded by the reinforcing reinforcing bars 9 embedded in the panel 2 as described above.
[0023]
The reason is that the region surrounded by the reinforcing reinforcing bars 9 embedded in the panel 2 has a significantly improved strength compared to the region not surrounded by the reinforcing reinforcing bars 9, so that the length of the rod-shaped body 7b is at least By setting the length to reach the area, the T-shaped bracket 7 is more firmly held by the panel 2. Thereby, the weak point of the ALC panel that the corners of the panel 2 are very likely to be chipped is compensated, and the T-shaped bracket 7 can be fixed near the end of the ALC wall 1.
[0024]
However, the length of the rod-like body 7b is preferably set to 300 mm or less in terms of weight, mounting workability, effect limit, and the like. Moreover, although the tubular body can be applied to the rod-like body 7b, a steel rod having a diameter of 5 to 20 mm is desirable from the viewpoint of strength and fixing workability.
The plate 7a is preferably disk-shaped with a diameter of 30 to 70 mm from the viewpoint of attachment workability, but may have other shapes such as a square.
[0025]
Further, as shown in FIG. 2, a countersink portion 11 into which the plate 7a is fitted is formed at the inlet 8a of the hole 8 into which the T-shaped fitting 7 is inserted, and the depth thereof is the surface of the plate 7a and the upper edge. It is formed so that the surface 1a is substantially flush, that is, exists on the same plane. As a result, the plate 7a of the T-shaped metal fitting 7 is not exposed on the upper small edge surface 1a, so that the design is improved. In addition, when the T-shaped metal fitting 7 is fixed, the space between the steel plate 10 and the upper small edge surface 1a is not opened. In the meantime, there is no accumulation of water.
[0026]
It is desirable that a gap 12 of about 2 to 5 mm is formed between the side wall of the counterbore 11 and the outer peripheral surface of the plate 7a. That is, when an earthquake or a large load is applied to the plate 7a, even if the position of the plate 7a is displaced, the force with which the outer peripheral surface presses the side wall of the countersink portion 11 is small, and the side wall of the countersink portion 11 is destroyed. Less. Without such a gap 12, the side wall is broken even if the plate 7a is slightly displaced, and if it is displaced greatly, cracks are likely to occur around it. Therefore, the configuration of the gap 12 as described above further contributes to the elimination of the disadvantage that the end of the ALC wall 1 is easily chipped. Therefore, the T-shaped metal fitting 7 is provided near the end 1b of the upper edge surface 1a of the ALC wall 1. This is a more preferable configuration when fixing.
[0027]
Next, the steel plate 10 is laid on the plate 7a of the T-shaped bracket 7 fixed as described above and fixed by welding. For example, as shown in FIG. 2, the welding fixing method is such that a hole 10 a is formed in a portion where the plate 7 a of the T-shaped bracket 7 of the steel plate 10 is welded in advance, and the inner periphery of the hole 10 a and the T-shaped bracket 7 are The plate 7a is fixed by welding. The width and thickness of the steel plate 10 are appropriately selected according to the width of the upper fore edge surface 1 a and the size of the handrail 3.
[0028]
Further, a handrail pillar 3a is fixed on the steel plate 10, and a handrail 3 is formed by providing a horizontal bar on the handrail pillar 3a. The means for fixing the handrail pillar 3a on the steel plate 10 is mainly by welding, but may be other means such as a bolt.
[0029]
Thus, in the present invention, the T-shaped bracket 7 is not limited to the position near the end on the upper edge surface 1a of the ALC wall 1 having the same height as in FIG. Of the walls having a level difference, the position near the end on the upper edge surface 1a of the ALC wall 1 portion continuous at the same height, or the upper edge edge 1a of the corner portion where the ALC wall 1 is formed orthogonally The present invention can also be applied to a position closer to the end of the.
[0030]
In the present invention, the T-shaped metal fitting 7 needs to be fixed at least at the positions near the end portions 1b on the upper edge 1a of the ALC wall 1 as described above. Further, it is preferable that the same structure is also fixed at the middle position on the upper fore edge surface 1a in order to ensure the mounting strength. Further, instead of the T-shaped bracket 7 at the intermediate position, a joint portion embedding member 14 as shown in FIG. 4 to be described later may be embedded in the joint portion 13, and the structure of the present invention is further strengthened. You may use them together in order to make it.
[0031]
Next, an embodiment in which the joint portion embedding member 14 is applied in place of the T-shaped bracket 7 at the position of the intermediate portion of the ALC wall 1 will be described.
As shown in FIG. 3 and FIG. 4, the joint portion 13 generally formed by abutting the side edge surfaces 2 a to each other is formed with a cavity 15 for connecting the panels 2 and filled with a mortar 16. . The joint portion embedded member 14 is embedded in the cavity 15 and fixed by a mortar 16. An upper end portion of the joint embedding member 14 protrudes through the through hole 10b of the steel plate 10, and a screw 17 is formed on the upper end portion to form a bolt 17. The steel plate 10 is fixed by screwing 18.
[0032]
The fixing method of the steel plate 10 is usually based on the following method. First, a steel plate having holes 10a and through holes 10b in two places on both ends is prepared, and the hole 10a portion is laid on the plate 7a of the T-shaped bracket 7 and fixed by welding. Further, the through hole 10 b is fixed to the joint portion 13 with a bolt 17 and a nut 18. The plurality of steel plates fixed in this manner are connected and integrated by welding the steel plates having a length between them, so that the steel plates are installed over the entire length of the upper fore edge surface 1a.
[0033]
According to the structure described above, the steel plate 10 can be laid and fixed simply by screwing the nut 18 into the bolt 17 at the upper end after the joint portion embedding member 14 is embedded in the joint portion 13 with the mortar 16 and solidified. Therefore, the installation work is also facilitated. Further, since the mortar 16 is hardened to several times the strength of the panel 2 after being solidified, the joint embedded member 14 becomes a stronger anchor of the steel plate 10. The joint embedding member 14 is usually a joint reinforcement, but may be a cylindrical body.
Further, the structure of the present invention is applied to an ALC wall when a handrail is attached to a rising ALC wall such as a veranda, a balcony, a corridor, a waist wall of a staircase, or a parapet.
[0034]
