Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mounting structure for an ALC vertical wall opening panel provided on an outer wall or a partition wall formed by arranging a plurality of ALC panels in a vertically long manner.
[0002]
[Prior art]
In the ALC vertical wall 80 composed of vertical wall ALC panels (hereinafter referred to as panels) 81 and 82 as shown in FIG. 5, the structure for fixing the panel of the opening 85 is as shown in FIG. A structure using a stopper 90 is conventionally known (Japanese Utility Model Laid-Open No. 51-13114). The locking device 90 is generally referred to as a driving-type lock fitting, and a plurality of foot portions 92 are formed at the driving head portion 93 and the body 91 and the tip portion 94 so as to be slightly opened when driven. It is a thing. In this conventional structure, the U-shaped reinforcing member 83 is fixed to the panels 81 and 82 of the opening 85 using the locking member 90.
[0003]
The fixing structure of the upper panel 81 of the opening 85 using the U-shaped reinforcing member 83 is formed as follows. That is, the locking tool 90 is driven from above the hole in a state where the U-shaped reinforcing member 83 provided with the through-hole is overlapped on the panel 81, 82 of the opening 85. At this time, as the locking tool 90 is driven, the tip end 94 side of the foot portion 92 is pushed and spread, and as a result, the foot portion 92 bites into the panels 81 and 82.
[0004]
The U-shaped reinforcing member 83 is fixed by the locking member 90 so as not to come off from the panels 81 and 82. In this way, the lower end of the upper panel 81 is fixed by being connected to both side panels 82 of the opening 85 via the U-shaped reinforcing member 83. This structure does not use a steel material such as a vertical angle for panel reinforcement, but only uses a U-shaped reinforcing material 83 and a locking tool 90, and therefore has a small number of members and is inexpensive.
[0005]
[Problems to be solved by the invention]
However, the conventional ALC vertical wall opening structure has a common cavity between the facets of the panels and fills the cavity (not shown) with a bonding material such as mortar to solidify the panels. By doing so, it is a structure of a so-called insertion muscle construction method in which each panel is integrated. In such a structure, since the panels are connected to each other or the panels and the casing are connected to each other by the bonding material, the U-shaped reinforcing material is also used for supporting and reinforcing the opening panel. Therefore, they needed a fairly thick and strong steel.
[0006]
Further, in the conventional mounting structure of the opening, it is necessary to support the upper panel and the U-shaped reinforcing material from below with a support bar or the like until the bonding material is solidified when the panel is mounted. Therefore, the mounting workability is poor and the mounting period is long. Furthermore, the conventional opening structure has a problem that it is vulnerable to earthquakes because the panels do not slide relative to each other.
Furthermore, if the locking tool of the reinforcing steel material is such a drive-in type locking fitting, the rigidity of the locking tool itself is low, so there is a limit to the load that can be supported by one fitting. In addition, when the locking tool is driven into the panel, the panel is often partially broken, and as a result, the required strength for mounting may be lowered. In order to compensate for these drawbacks, it was necessary to use a large number of locking tools.
[0007]
The object of the present invention is to solve the above-mentioned problems and to have excellent earthquake resistance, and it is sufficient to reduce the thickness of the reinforcing member even though there are few attachment parts and parts to be used for the opening reinforcing material. An object of the present invention is to provide a mounting structure for an ALC vertical wall opening panel having strength and excellent durability.
[0008]
[Means for Solving the Problems]
The mounting structure of the ALC vertical wall opening panel of the present invention that solves the above-described problems has the following configuration.
The mounting structure of the present invention is an ALC vertical wall opening panel mounting structure in which an opening of an ALC vertical wall is formed by both side panels of the ALC and upper and lower panels, and a reinforcing steel material is provided on the inner periphery of the opening. The side edge surfaces of the side panels and the upper and lower panels are in contact with each other so as to be slidable in the vertical direction, and the central portion in the width direction of the upper part of the upper panel of the opening can hang down the upper panel. It is attached to the building frame by the upper mounting member, the lower part of the upper panel is attached to the reinforcing steel material by the lower mounting member, and the reinforcing steel material is attached to the small edge surfaces of the side panels facing the opening. It is the attachment structure of the ALC vertical wall opening panel characterized by being locked by a locking tool.
[0009]
The operation of the present invention will be described below.
According to the present invention, since the central portion in the width direction of the upper part of the upper panel of the opening is attached to the building frame by the attachment member that can hang the upper panel, most of the weight of the panel can be supported by the attachment member. As a result, it is sufficient for the reinforcing steel material to be able to withstand the wind pressure applied perpendicularly to the panel surface, and therefore it is not necessary to be directly connected to the building frame, and the thickness can be reduced. In addition, since the bonding material is not filled between the side edge surfaces of the panels, they are slidably contacted in the vertical direction, so that the panels are relatively rocked to release external forces. And become strong against earthquakes.
[0010]
Further, in the present invention, when at least the upper mounting member of the upper and lower mounting members of the upper panel is formed of an anchor member embedded in the upper panel, the anchor member is not easily removed, so that a stronger structure is obtained.
[0011]
Furthermore, as a reinforcing steel material in the present invention, using a U-shaped reinforcing material in which the upper panel and both side panels, the lower panel and both side panels are combined, the structure is fixed to the upper and lower sides of the inner periphery of the opening. The function can be exhibited with a small amount of the used member, and the cost can be further reduced.
[0012]
In addition, the frame steel material provided along the entire inner circumference of the opening may be used as the reinforcing steel material.In this case, the amount of the used member is slightly increased, but the reinforcement is performed over the entire circumference of the edge of the opening. The structure is greater in strength and superior in durability.
[0013]
The locking tool has a rod-shaped rigid body, and the rod-shaped rigid body is inserted into a hole surrounded by reinforcing bars embedded in both side panels in a hole opened in the small edge surface of both side panels. It is desirable.
[0014]
That is, if the locking tool is a rod-like rigid body, unlike the structure in which it is fixed by a conventional driving-type lock fitting, a load such as wind pressure applied to the reinforcing steel material can be securely transmitted to both side panels. Further, since the rod-like rigid body is inserted into the hole previously opened in the small facet, the panel is not destroyed. In addition, in this case, since the rod-like rigid body is supported in the region where the strength of the panel is increased by the reinforcing bars, both side panels can firmly support the locking tool also in this respect. .
[0015]
Further, it is desirable that the locking member has a plate fixed to one end of the rod-shaped rigid body perpendicular to the rod-shaped rigid body.
In this way, the locking tool to which the plate is fixed is inserted in the hole previously formed in the small edge surface of the both side panels, and then the reinforcing steel material is fixed to the plate, thereby fixing the plate of the present invention. Since the mounting structure can be configured, mounting workability is improved. Moreover, since the locking tool and the reinforcing steel material can be fixed by welding or the like over a wide area of the plate, a strong structure is obtained.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
As shown in FIG. 1, the ALC vertical wall W is formed by arranging a plurality of side panels 1, an upper panel 2 and a lower panel 11 in a vertically long shape, and is supported by a building frame erected vertically. Thus, an opening 6 is formed. The joint portions of the side edge surfaces 10 of the panels 1, 2 and 11 are not filled with a bonding material such as mortar, and the edge surfaces 10 are in contact with each other so as to be slidable in the vertical direction. Note that the height of the panels 2 and 11 above and below the opening may be shorter than the width.
[0017]
Among these, the upper panel 2 of the opening 6 is attached to the panel support part Ka of the building frame K by the panel upper attachment member 3 at the upper part of the panel. The panel support portion Ka of the building frame K has a horizontal flange portion welded and fixed to the lower surface of a beam made of H-shaped steel installed on the upper side of the ALC vertical wall W so that the vertical flange portion faces downward. Made of mold steel.
The upper mounting member 3 is made of a member capable of drooping the upper panel 2 in strength. In the embodiment shown in FIG. 2, the upper mounting member 3 has an anchor member 3a embedded in the upper portion of the upper panel 2 and an axis perpendicular to the panel surface. Although it is composed of screws 3b (bolts and nuts in FIG. 2), a lightning bolt 3c having a lightning-shaped longitudinal section is also used to fit the vertical flange portion of the L-shaped steel.
[0018]
Panels 1, 2, and 11 are made of a pair of steel bars welded in a grid and bent into a C shape, or a pair of steel bars welded in a grid to form a mat. And the like that are connected to each other are present inside the reinforcing bars 9. In the present embodiment, a metal fitting with a reinforcing flange that is welded and fixed to a panel reinforcing bar 9 that is approximately 5 to 15 cm apart in the vicinity of both ends and exists in the panel in parallel is used as the anchor member 3a. However, if the anchor member 3a has a sufficient length and rigidity, it is possible to obtain a strength for allowing the upper panel 2 to hang down even if it is not fixed to the reinforcing bar 9.
[0019]
The anchor member 3a is coupled to the nut so that the axis of the threaded portion of the nut is perpendicular to the panel surface. Moreover, the top face of the nut is exposed from the panel in a countersink hole dug from the panel surface side. Further, a mounting hole for the lightning bolt 3c is aligned with the entrance of the screw hole of the nut, and a bolt as a screw 3b is screwed into the nut with a washer from the outside. The opposite side of the lightning bolt 3c is welded and fixed to the L-shaped steel with the portion and the surface of the upper panel sandwiching a vertical flange portion of the L-shaped steel as the panel support portion Ka of the building frame K. .
If the upper panel can be suspended, a hook bolt or the like can be used as the upper mounting member 3.
[0020]
In this way, the lower side of the upper panel 2 attached to the panel support part Ka of the building frame K by the upper mounting member 3 is disposed on both side panels 1 via the opening upper reinforcing steel material 7a as shown in FIG. Installed on.
The upper reinforcing steel material 7a includes a horizontal plate portion 7aa extending horizontally across the entire width of the opening 6 along the lower end 2a of the upper panel 2, and the openings of the both side ALC panels 1 from the left and right ends of the horizontal plate portion 7aa. The side plate piece portion 7ab extends downward along the small edge surface 1a facing the portion 6, and has a U-shape as a whole. Since most of the weight of the upper panel 2 is supported by the mounting member 3 at the top of the panel 2, the thickness of the horizontal plate portion 7aa and the side plate piece portion 7ab can be reduced. Further, it is further preferable that rib processing or the like is applied to the horizontal plate portion 7aa and the side plate piece portion 7ab.
[0021]
Further, the fixed piece 7ac of the upper reinforcing steel material 7a is formed by welding by forming an L shape so as to stand along the surface of the upper panel 2 from the portion along the lower end 2a of the upper panel 2 of the horizontal plate portion 7aa. A panel lower mounting member 8 made of an anchor member 8 a is embedded in the lower portion of the upper panel 2. The anchor member 8a is connected to the fixed piece 7ac via a screw 8b (consisting of a bolt and a nut) having an axis perpendicular to the panel surface. In this embodiment, the anchor member 8a is the same as the anchor member 3a embedded in the upper part of the upper panel 2 in order to make the parts common. However, the anchor member 8a in this portion is not so strong. However, other members may be used.
[0022]
Further, as shown in FIG. 4, a hole 4 is formed in the small edge surface 1 a facing the opening 6 of the both side panels 1 in a direction perpendicular to the small edge surface 1 a, and the locking tool 5 is inserted into the hole 4. A rod-shaped rigid body 5b is inserted, and a side plate piece portion 7ab of the upper reinforcing steel material 7a is fixed to the base portion thereof. In the present embodiment, the rod-like rigid body 5b makes it easy to join the reinforcing steel material 7 by welding. Therefore, a circular plate 5a is fixed to the base of the rod-like rigid body 5b as a welding base. Therefore, the locking tool 5 is usually a metal fitting, and a protrusion 5c is formed on the surface of the rod-shaped rigid body 5b so that the rod-shaped rigid body 5b does not wobble in the hole 4.
[0023]
The plate 5a of the locking tool 5 is preferably a disk having a diameter of 3 to 7 cm from the viewpoint of attachment workability, but may be other shapes such as a square.
Further, the rod-like rigid body 5b of the locking tool 5 is desirably a cylindrical column made of steel having a diameter of 5 to 20 mm from the viewpoint of strength and workability, but may be a tubular member. Further, the reinforcing bars 9 are embedded in the both side panels 1 in the same manner as the upper panel 2 described above, but the length of the locking member 5 is at least the reinforcing bars embedded in the both side panels 1. 9 has a length up to the inside of the region 9a, and the tip of the rod-like rigid body 5b is inserted into the region 9a.
[0024]
Since the strength of the region 9a surrounded by the reinforcing bars 9 on both side panels 1 is greatly improved as compared with the region that is not embedded, the length of the rod-shaped rigid body 5b is set to at least the region 9a. By setting the length to reach, the rod-like rigid body 5b, that is, the locking tool 5 is firmly held by the both side panels 1. However, it is preferable that the maximum is 30 cm or less in terms of weight, mounting workability, and the limit of effects.
[0025]
Further, as described above, the protrusion 5c of the rod-shaped rigid body 5b is formed at a predetermined position between the center of the rod-shaped rigid body 5b and the plate 5a. That is, by projecting at such a position, the backlash of the rod-like rigid body 5b inserted into the hole 4 can be suppressed at a position close to the plate 5a, so that the reinforcing steel material 7 can be firmly and firmly loosened. Can be fixed.
[0026]
On the contrary, if the protrusion 5c of the rod-like rigid body 5b of the locking tool 5 is located on the tip side from the center, a rattling occurs between the protrusion 5c on the tip side and the plate 5a, It cannot be fixed. Moreover, the whole locking tool 5 comes to rattle near the inlet 4b of the hole 4, and as a result, the both side panels 1 near the inlet 4b are gradually destroyed.
[0027]
In addition, it is desirable that the height of the protruding portion 5c is 1 to 5 mm in terms of ensuring fixation. In addition, the length of the protrusion 5c is such that several protrusions having a length of about 2 to 6 mm are provided, a plurality of such protrusions 5c are provided in series, and further the center position. The protrusion 5c which continues from the near chamber of the plate 5a to the projection may be provided. In addition, it is preferable to provide the protrusion 5c at a portion 5 mm or more away from the plate 5a of the rod-like rigid body 5b so that the vicinity of the inlet 4b of the hole 4 is not broken. The protruding portion 5c can be easily formed by picking out the side surface of the rod-shaped rigid body 5b with a press or the like.
[0028]
In addition, a countersunk portion 4a into which the plate 5a is fitted is formed at the inlet 4b of the hole 4 into which the rod-like rigid body 5b of the locking tool 5 is inserted, and the depth of the surface 5d of the plate 5a and the small edge surface 1a is reduced. Since the plate 5a of the locking tool 5 is not exposed to the opening 6 by being substantially flush with each other, that is, being formed on the same plane, the side plate pieces 7ab and both sides of the upper reinforcing steel material 7a are not exposed. There is no space between panel 1 and there is no need to fill the space.
[0029]
Further, it is desirable that a gap 4c of about 2 to 5 mm is formed between the side wall 4d of the countersunk portion 4a and the outer peripheral surface 5e of the plate 5a. That is, when an earthquake or a large load is applied to the plate 5a, even if the position of the plate 5a is shifted, the force that the outer peripheral surface 5e presses the side wall 4d of the countersink portion 4a is small, and the side wall 4d of the countersink portion 4a is Less destruction. On the other hand, if there is no gap 4c, the side wall 4d is broken even if the plate 5a is slightly displaced, and if it is greatly displaced, cracks are likely to occur around it.
[0030]
As described above, the side plate pieces 7ab of the upper reinforcing steel material 7a are fixed to the both side panels 1 with the rod-like rigid body 5b of the locking tool 5, but the upper panel 2 of the opening 6 is connected to the horizontal plate of the upper reinforcing steel material 7a. In order to fix to the part 7aa, the rod-like rigid body 5b of the locking tool 5 may be used instead of the structure as described above.
[0031]
Furthermore, the opening lower reinforcing steel material 7 b is attached to the lower panel 11 of the opening 6 with a structure that is upside down with respect to the mounting structure of the upper panel 2.
That is, the horizontal plate 7ba horizontally extending over the entire width of the opening 6 along the upper end 11a of the lower panel 11, and the openings 6 of the both side panels 1 from the left and right ends of the horizontal plate 7ba. An upper portion of the lower panel 11 is supported by a lower reinforcing steel material 7b having a side plate piece portion 7bb extending upward along the small facet 1a and forming a U-shape as a whole.
[0032]
Further, the side plate piece 7bb of the lower reinforcing steel material 7b is fixed to a rod-like rigid body 5b inserted into the hole 4 opened in the small face 1a facing the opening 6 of the both side ALC panel 1. Further, the lower part of the lower panel 11 is attached to the building frame K by the same attachment member as that of the upper panel 2. For other details such as the fixed piece portion 7bc, the mounting structure of the upper panel 2 can be used to make most of the mounting members of the upper and lower panels common.
[0033]
In this case, by connecting the side plate piece 7ab of the upper reinforcing steel material 7a and the side plate piece 7bb of the lower reinforcing steel material 7b with the connecting member 7c, the reinforcing frame provided over the entire periphery along the edge of the opening 6 Can be formed. If the reinforcing steel material 7 is such a frame-type steel material, the amount of members used is slightly increased, but since the reinforcement is made over the entire circumference of the edge of the opening, the structure is stronger and more durable. Become. In this way, a window or the like is attached to the upper reinforcing steel material 7a, the lower reinforcing steel material 7b and the connecting member 7c attached to the both side panels 1 by welding or the like. Therefore, the upper and lower reinforcing steel members 7a and 7b and the connecting member 7c may support a load in a direction perpendicular to the ALC vertical wall W. Therefore, it is not necessary to use such a strong steel material as the material of these reinforcing steel materials, and even a thin steel material can be used, and the cost can be reduced.
[0034]
【The invention's effect】
As described above, according to the mounting structure of the ALC vertical wall opening panel according to the present invention, most of the weight of the upper panel is supported by the mounting member, so that the weight of the upper panel does not significantly affect the reinforcing steel material of the opening. Therefore, it is not necessary for the reinforcing steel material to be connected to the building frame, and the thickness of the reinforcing steel material can be reduced. In addition, the mounting structure of the ALC vertical wall opening panel can be reduced in the number of mounting portions and the number of parts of the reinforcing material in the opening and is excellent in durability. Furthermore, it is not necessary to use a bonding material such as mortar to integrate the panels, and each ALC panel has a small slidable contact with each other so that it has excellent earthquake resistance. Become.
