DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a panel such as lightweight cellular concrete (hereinafter referred to as ALC) as a vertical wall to an outer wall of a building, particularly when a wide panel having a width of 90 cm or more is attached. It is intended to provide a structure suitable for:

[0002]

2. Description of the Related Art Conventionally, various structures have been proposed as a structure in which a wide panel such as an ALC plate is attached as an outer wall of a building. For example, as shown in FIG.
The upper ruler angle 3 and the lower ruler angle 18 are welded and fixed to the upper and lower surfaces of the upper flange 2, and the receiving bracket 15 is welded to the connection portion of the upper panel 4 a adjacent to the upward ruler angle 3 to weld the panel 4 a. To support the lower end. The reinforcing bar 1 is inserted into the grooves 16 on both sides of the upper panel 4a.
The groove 16 is filled with cement mortar and fixed. Further, as shown in the lower panel 4 in the figure, the upper end of the panel is provided with a bolt 19 penetrating through holes formed near both upper ends in the width direction, and an inazuma plate 20 is attached to the back surface of the panel 4. Inazuma Plate 20
Thus, the downward ruler angle 18 is held therebetween. This structure is a so-called slide method in which the lower end of the panel is fixed to the skeleton and the upper end is slightly movable in the horizontal direction with respect to the skeleton, and the quake resistance is also considered.

[0003] However, this method uses a downward ruler angle 1
8 and the work to attach the progress plate 20
In addition, the workability is poor because the work is performed on the back side of the work, and there are many on-site work such as welding of the receiving bracket 15 and the reinforcing bar 17, spotting and repairing of the panel 4, and filling of cement mortar, so that it takes time and effort, and the construction period becomes longer. was there. Further, there is a problem that a panel in which a bolt fixing metal is embedded cannot be used.

As another structure, Japanese Patent Application No. 63-85867 filed earlier by the present applicant is disclosed in FIGS. 8 (A) and 8 (B).
As shown in the figure, a ruler 21 is fixed to the beam 1 near both ends in the width direction of the panel, and a cutout portion of the ruler 21 is
Inazuma hardware 2 attached to the upper end of the lower panel 4
2 is inserted, and an insert 23 having an L-shaped cross section is inserted in the opposite direction and fixed. Also, a height adjusting metal piece 24 having a U-shaped cross section.
Is fastened to the insertion hardware 23, and the height adjustment hardware 2
4, the upper panel 4 a is sandwiched between the vertical portions of the weight-bearing metal fitting 25 having a stepped shape with the bolts 26 and embedded metal 2 of the panel 4 a is used.
7, the lower end of the upper panel 4 a is supported by the weight holder 25, and the height of the upper panel 4 a can be adjusted by a bolt 28 attached to the top of the weight holder 25. There is something.

However, in this structure, since the embedded metal 27 bears the rotational force and wind pressure due to the weight of the panel 4a, large strength is required depending on the weight and area of the panel. In addition, there is a problem in that the shape and the number of mounting hardware are complicated and many, so that cost and trouble are required.

As another structure, as shown in FIG. 9 (A), an upward ruler angle 3 fixed to a beam 1 and a tip end of a fastener 22 attached to an upper end of a lower panel 4.
9B is clamped by a metal piece 29 having a U-shaped cross section as shown in FIG. 9B, and further this metal piece 29 is clamped by a fastener metal piece 30 attached to the lower end of the upper panel 4a. The weight of the upper panel 4a is supported by an angle (not shown) fixed to the upward ruler angle 3 separately.

However, in this structure, only the tip of the fastener 22 attached to the upper end of the lower panel 4 is in contact with the ruler angle 3, so that the large wind pressure applied to the panel 4 is borne by the fastener 22. However, it is necessary to increase the width and thickness of the hardware, and there is a problem that costs and trouble are required.

Further, in these conventional slide methods, the lower end portions on both sides in the width direction of the panel are fixed to beams, and the upper end portions on both sides have a structure that can move slightly in the horizontal direction. However, as shown in FIG. Suddenly moves horizontally, a rotational force is generated in the panel 4, and the weight 31 serving as a fulcrum of rotation.
An excessive load is applied to the As a result, the weight receiver 31 comes off, and the panel 4 and the inazuma plate 3
There was a risk that the attachment portions of 2, 33 would be damaged.

Also, in the case of using the weight receiving hardware capable of adjusting the height of the panel, since the lower end of the panel is generally fixed to the weight receiving hardware with bolts, the outward couple of the panel, the negative pressure, and the like are reduced. This is borne by the fittings between the hardware, the frame and the panel, but an excessive load is applied to the fitting depending on the weight and area of the panel. As a result, there is a risk that the weight receiving hardware may come off, be deformed, or the mounting portion of the panel may be damaged.

Further, when a strong pulling force is applied to the panel, the end of the inazuma plate used to attach the panel to the frame is damaged by the biting of the panel or the bolted portion. There was a problem such as bending.

[0011]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a mounting structure for an outer wall panel which is easy to construct a wide panel and has excellent seismic resistance and appearance. It is assumed that.

[0012]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a mounting structure of an outer wall panel for locking an outer wall panel which is vertically connected to a ruler angle fixed to an upper edge of a beam. Then, the fastening degree of the bolts is set to such an extent that the panel and the inazuma plate can move freely through the washer on the upper part of the upper panel inazuma plate fixed to the set plate in which the lower end of the upper panel is fixed to the ruler angle. An outer wall panel in which the bolt is welded to the washer and the lower part of the set plate suspended from the ruler angle above the lower panel inazuma plate fixed to the upper edge of the lower panel so as to be freely movable.

As described above, according to the present invention, the lower end of the upper panel is loosely screwed through the washer to the upper surface of the inazuma plate fixed to the set plate fixed to the ruler angle fixed to the upper edge of the beam. Therefore, even if the frame suddenly horizontally moves during an earthquake and a rotational force is generated in the panel, the panel moves upward and no excessive load is applied to the weight receiving hardware. In addition, it is a slide method that is easy to work by simply movably holding the lower part of the set plate suspended from the ruler angle above the inazuma plate fixed to the upper end of the lower panel, and the positive wind pressure on the panel is Since the skeleton bears through, the inazuma plate is not overly burdened.

According to the present invention, a step-shaped receiving plate capable of adjusting the position in the vertical direction is attached to a support plate fixed to a beam so as to be able to ascend and descend to form a panel's own weight receiver, and is not connected to the panel. It is also possible to prevent an excessive load from being applied to the mounting portion of the motor and the progress plate.

Further, as shown in FIG. 3 (E), a progress plate 7 shown in FIG. 3 (E) used for the mounting structure at the lower end of the panel is formed by bending an iron plate in a stepped manner in the same manner as the progress plate 5, and has a surface fixed to the panel. A vertically long through hole 7a for inserting a bolt is formed, and a rib 7b is provided on both sides in the width direction of this surface on the side opposite to the panel. The washer 8 interposed between the progress plate 7 and the bolt is shown in FIG.
As shown in (D), a through hole 8a for inserting a bolt is formed in the center, and both ends in the width direction are provided with the ribs 7b.
A step 8b that fits between them is formed.

If desired, a lower end face of the panel may be provided with a support which can be provided to support the weight of the panel. The support is provided with a support plate 9 as shown in FIG. 3 (G).

The support plate 9 has a U-shaped cross section, and a notch 9a for holding a mounting bolt is provided at the upper end of a vertical plane. A bent portion 9b is formed.

The receiving plate 10 is formed by bending a flat plate in a stepped manner, and has a through hole 10a through which a mounting bolt is inserted near an upper end of a vertical portion, and a through hole through which a height adjusting bolt is inserted through a horizontal portion. 10b is drilled, and a nut 10c is fixed to the back side of the through hole 10b.

Next, FIGS. 1, 2 and 4 show an outer wall structure and a construction method of a panel using the above-described mounting hardware.
This will be described below. A ruler angle 3 is fixed outward, horizontally and parallel to the skeleton on the upper surface of the H-beam 1 that forms the skeleton of the building. On the other hand, a bolt plate 26 is fastened to the vicinity of the upper end portion on both sides in the width direction of the lower wide panel 4 so as to open upward.

In the vicinity of the lower end portions on both sides in the width direction of the upper panel 4a, bolts 26 are similarly fastened via washers 8 so as to open the lower part of the inazuma plate 7 at a position facing the above-mentioned inazuma plate 5. .

When the mounting position of the lower panel 4 is determined, the lower end of the set plate 6 is inserted into the upper opening of the inazuma plate 5 and the vertical portion of the ruler angle 3 can move freely with the hook-like portion 6a at the upper end. And welded on both sides.

The set plate 6 'used in this embodiment is a flat plate having a hook-shaped portion 6'a having an upper end bent in a U-shape as shown in FIG. 6 (C). The vertical portion of the ruler angle 3 is movably clamped and suspended and welded to the ruler angle 3.

On the other hand, as shown in FIG. 6 (A), an inner plate 7 'made of a flat plate and having a through hole 7'a at its upper end is welded to the opposite side of the hook-shaped portion 6'a from the panel. ing. (See FIG. 5) When the upper panel 4a is attached, the bolt 26 is slightly loosely attached to the upper panel 4a through the through hole 7'a to adjust the degree of tightening of the bolt 26, and then the bolt 26 is used to prevent loosening. Weld the progress plate. At this time, in order to more effectively prevent loosening, as shown in FIG. 6 (A), both ends of the inazuma plate 7 'are bent downward so as to hold both ends thereof, and a washer 8' formed in a U-shape is bolted. The bolt 26 and the washer 8 'can also be welded between the bolt 26 and the progress plate 7'.

The above-mentioned panel mounting structure uses the lower mounting structure of the upper panel, its own weight receiving structure, and the upper mounting structure of the lower panel independently, and the other structures may be conventional structures. You may use combining structures.

[0033]

As described above in detail, the mounting structure of the outer wall panel of the present invention allows the lower end of the upper panel to float on the upper surface of the inazuma plate fixed to the ruler angle fixed to the upper edge of the beam via the washer. By screwing as much as possible,
If the frame suddenly moves horizontally during an earthquake and a rotational force is generated in the panel, the panel moves upward, so that an excessive load is not applied to the weight receiver. In the case of a lightweight panel, the lower end of the upper panel can be screwed onto the upper part of the inazuma plate fixed to the set plate fixed to the ruler angle, so that the mounting structure can be manufactured at low cost. The upper part of the inazuma plate fixed to the upper end of the lower panel, the lower part of the set plate suspended from the ruler angle is simply movably clamped, so the slide method is easy to construct, and the positive wind pressure on the panel is positive. Since the skeleton bears through, the excessive load is not applied to the inazuma plate.

In the present invention, the ribs are provided on the progress plate, so that there are advantages such as deformation at the panel mounting portion, damage to the panel, and no slipping of the upper washer.
