Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure which is advantageous when the ALC outer wall panel is mounted to the body from the indoor side.

[0002]

2. Description of the Related Art Since ALC panels (lightweight cellular concrete panels) have high heat insulation and fire resistance, they are often used as outer wall panels of steel frame structures and wooden structures. Especially, AL with a thickness of 50 mm or less
Since the C panel is easy to handle, it is used by being fixed to a wooden pillar with nails or screws, or by being fixed to a C-shaped channel through a fixing metal object. However, this ALC panel has characteristics of lower strength and brittleness as compared with general concrete panels.

Here, a mounting structure for fixing a relatively thin ALC panel to a building will be described with reference to the drawings.

FIG. 5 shows a structure for fixing the ALC panel 51 from the outdoor side. As shown in the figure, the ALC panel 51 is fixed to a wooden column 52 with screw nails or wood screws 53. In this case, in order to avoid exposing the head of the wood screw 53 on the surface of the ALC panel 51, the ALC of the head is removed.
It is buried in the panel 51 and the buried portion is repaired.

With the above-mentioned mounting structure, the strength against peeling of the ALC panel 51 to the outdoor side can be increased.
After the LC panel 51 is attached to the pillar 52, the surface of the panel 51 must be repaired. In particular, when the ALC panel 51 has a surface coated beforehand, it is difficult to repair it so as to be inconspicuous by including this coating layer.

FIG. 6 shows a structure for fixing the ALC panel 51 from the indoor side. As shown in the figure, an anchor steel bar 54 is inserted into a hole formed in the width direction of the ALC panel 51, and an O bolt mounted on the anchor steel bar 54.
The screw side of 55 is exposed on the inside surface. A Z plate 56 is attached to the O bolt 55, and the ALC panel 51 is fixed by the engagement of the plate 56 and the C-shaped channel 57.

In the above-mentioned mounting structure, when the ALC panel 51 is thin, a technique is required to form a hole for inserting the anchor steel bar 54 in the panel 51, and a Z plate 56 for fixing is required. There is a problem of rising.

FIG. 7 shows a structure for fixing the ALC panel 51 from the indoor side. As shown in the figure, the ALC panel 51 is attached to the column 52 with wood screws 53 via L-shaped attachment fittings 58 arranged in the width direction and the length direction. That is, one piece of the mounting bracket 58 is A by the wood screw 53.
The panel is fixed to the surface of the LC panel 51 on the indoor side, and the other piece is similarly fixed to the column 52 by wood screws 53, thereby
51 is fixed to the pillar 52.

In the above-mentioned mounting structure, since the mounting strength of the ALC panel 51 (resistance to the force for peeling the ALC panel 51 to the outdoor side) is low, in order to obtain the required strength, there are a plurality of locations in the width direction and the length direction. It is necessary to fix with.
Therefore, when stress concentrates on the mounting portion of the mounting bracket 58, the ALC panel 51 may be partially damaged.
In particular, as shown in FIG. 8, when the column 52 tilts due to the deformation of the body that occurs during an earthquake and a relative rotational force acts between the column 52 and the ALC panel 51, this rotational force should be absorbed. However, since the force acts on the wood screw 53 and the ALC panel 51 as a shearing force, the panel 51 is more likely to be damaged.

[0010]

As described above, the conventional mounting structures have both advantages and disadvantages. Therefore, it is required to develop a mounting structure that has a simple structure and can be mounted on the body without damaging the ALC panel.

An object of the present invention is to attach a relatively thin ALC outer wall panel to a column with a simple structure and to disperse the force acting on the panel to reduce the risk of breakage. It is to provide a mounting structure.

[0012]

In order to solve the above problems, an ALC outer wall panel mounting structure according to the present invention has a mounting hardware having an insertion piece and an insertion portion having a step corresponding to the thickness of the insertion piece. And a fixing piece formed with the fixing piece, the fixing piece is fixed to the indoor side surface of the ALC outer wall panel with a nail or a screw, and the insertion piece of the attachment piece is inserted into the insertion part of the fixing piece. It is fixed to the ALC outer wall panel via a nail or a screw in a state in which it can be freely rotated in the plane direction in the insertion portion, and the mounting metal object is fixed to the body with a nail or a screw.

[0013]

In the above mounting structure, the ALC outer wall panel (hereinafter,
A fixed metal object in which an insertion part having a step is formed on the indoor side surface of a "panel" is fixed with a nail or a screw (hereinafter, typically referred to as "a screw"), and an insertion piece of the mounting metal object is inserted into this insertion part. , And both are fixed to the panel with one screw, and further, the mounting hardware is fixed to the body with screws, so that at least three screws are arranged on the panel side at the attachment site between the panel and the body. .

Therefore, the mounting strength against the force for peeling the panel to the outside can be improved, and the force acting in the same direction as the surface of the panel is dispersed and supported by the respective screws. Therefore, the load applied to each screw can be reduced, and the risk of panel damage can be reduced.

Further, since the insertion piece of the mounting metal piece and the insertion portion of the fixed metal piece are fixed to the panel by one screw, the width dimension of the insertion portion is made larger than the width dimension of the insertion piece, so that the panel is attached to the frame. The mounting hardware can be configured to be rotatable relative to the panel while maintaining the strength and the fixed state of the fixed hardware to the panel. Therefore, when a plurality of fixed hardware are fixed on the center line in the width direction of the panel and each fixed hardware is attached to the skeleton through the mounting hardware, each mounting part is changed according to the deformation of the skeleton that occurs during an earthquake. Since the mounting hardware and the panel rotate relative to each other, the panel can be prevented from being damaged regardless of the deformation of the body.

Is a plan view of the mounting structure according to the first embodiment, FIG. 3 is a perspective view of the mounting structure according to the second embodiment, and FIG. 4 is a diagram for explaining the behavior of the panel when the body is deformed.

In the mounting structure shown in FIGS. 1 and 2, when the panel 1 is mounted on the pillar 2 constituting the frame, the mounting hardware 3 is formed in an L shape and includes the insertion piece 3a and the mounting piece 3b, and the insertion piece 3a. The attachment strength of the panel 1 is improved by using the insertion part 4a for inserting the and the fixed metal piece formed in the hat shape including the fixing piece 4b.

The panel 1 is composed of a relatively thin panel having a thickness of 50 mm or less and 50 mm or less. In this embodiment, when constructing an outer wall of a building, the long side direction of the panel 1 is arranged laterally and arranged vertically. The so-called horizontal structure is adopted. The pillars 2 forming the body are formed by C-shaped channels made of wood or steel, and include main pillars and studs. Therefore, the panel 1 is attached to the mounting hardware 3 and the fixed hardware 4 at a plurality of positions in the longitudinal direction.
It is attached to the pillar 2 via.

The mounting hardware 3 is formed by bending a strip having a predetermined thickness and width at a substantially right angle to insert the strip 3a and the strip 3b.
Is formed in an L shape. The thickness of the strip plate forming the mounting hardware 3 is not particularly limited, and may be any thickness that allows the screw nails or the wood screws 5a and 5b to be easily driven. However, when a prepared hole is formed in advance at a predetermined position, it is possible to use a material such as a commercially available angle material.

The fixed metal member 4 is formed in a hat shape by bending a band plate having a predetermined thickness and width. That is, in the center of the fixed metal piece 4, there is formed a stepped portion larger than the thickness of the insertion piece 3a of the mounting metal piece 3 and an insertion portion 4a having a width larger than the width dimension of the insertion piece 3a, and on both sides of the insertion portion 4a. The fixed piece 4b is formed. The thickness of the strip plate forming the fixed metal object 4 is not particularly limited, and may be any thickness as long as the screw nails or the wood screws 5a and 5b can be easily driven.

In this embodiment, the panel 1 is attached to the pillar 2 through the mounting metal piece 3 and the fixed metal piece 4 which are arranged at a position substantially corresponding to the center of the panel 1 in the width direction and corresponding to the pillar 2.

That is, the fixing hardware 4 is arranged at the position on the indoor side 1a of the panel 1 at the center in the width direction and at the position corresponding to the pillar 2, and the fixing pieces 4b on both sides are respectively attached to the panel by one wood screw 5a. It is fixed at 1. Further, the insertion piece 3a of the mounting hardware 3 is inserted into the approximate center of the gap formed between the insertion portion 4a of the fixed hardware 4 and the surface 1a of the panel 1, and the insertion portion 4a is inserted.
And the insert piece 3a is fixed to the panel 1 by one wood screw 5b. Further, the mounting piece 3b of the mounting hardware 3 is fixed to the corresponding pillar 2 by one wood screw 5a.

As described above, the panel 1 is attached to the pillar 2 at a plurality of positions in the longitudinal direction on the center line in the width direction, and the panel 1 and the fixed metal member 4 are attached to each of the attaching positions by three wood screws 5a and 5b. Connected and panel 1 with one wood screw 5b
And the mounting hardware 3 are connected.

Therefore, the panel 1 and the mounting hardware 3 have wood screws 5
It is connected so as to be relatively rotatable around b. In addition, since the panel 1 and the fixed hardware 4 are connected by the three wood screws 5a and 5b at each mounting location, the peeling force of the panel 1 is dispersed to the individual wood screws 5a and 5b. It is possible to improve the resistance force to, that is, the mounting strength of the panel 1.

In the outer wall constructed by attaching the plurality of panels 1 to the pillar 2 as described above, when the pillar 2 is inclined as shown in FIG. 4 (a) due to the deformation of the skeleton caused by the earthquake, As shown in FIG. 2B, the inclination of the pillar 2 is a wood screw 5b.
Can be absorbed by relative rotation (rocking) between the mounting hardware 3 and the panel 1, with no shearing force acting on the wood screw 5a and the panel 1, Will not be damaged.

FIG. 3 is a view for explaining the mounting structure according to the second embodiment. In this embodiment, when fixing the fixed metal piece 4 to the indoor surface 1a of the panel 1, the two fixing pieces 4b of the metal piece 4 are fixed by two wood screws 5a.

Therefore, the panel 1 and the fixed hardware 4 are connected by the five wood screws 5a and 5b, and it is possible to further improve the resistance to the force for peeling the panel 1 to the outdoor side. Further, the inclination of the pillar 2 due to the deformation of the skeleton that occurs at the time of the earthquake causes the wood screw 5 to be the same as in the above-described embodiment.
It can be absorbed by the relative rotation generated between the mounting hardware 3 and the panel 1 around b.

[0028]

As described in detail above, in the mounting structure according to the present invention, the panel is mounted from the indoor side to the body, so that the surface on the outdoor side is not damaged. Therefore, it is not necessary to repair the panel, and a good surface condition can be maintained. In particular, it is advantageous when using a precoated panel.

Further, since the panel and the individual fixed metal parts are connected at at least three places, it is possible to disperse the in-plane and out-of-plane forces acting on the panel. For this reason,
The force acting on one connection point is reduced, and the risk of panel damage can be reduced.

Further, since the panel and the individual mounting hardware are connected by a single wood screw, the panel and the mounting hardware are allowed to rotate relative to each other around the wood screw. Therefore, when a horizontal force acts on the body during an earthquake to deform it, the inclination of the column resulting from this deformation can be absorbed by the relative rotation of the mounting hardware and the panel. In particular, when fixing hardware and mounting hardware are placed on the center line in the width direction of the panel and the panel is mounted on the frame, the entire outer wall is locked due to the deformation of the frame during an earthquake, and the panel is prevented from being damaged. It has features such as being able to.
