Abstract

PROBLEM TO BE SOLVED: To make it possible to mount a panel definitely from the surface side by providing a header face contact piece so as to form a small spacing with an erected piece formed on one end of a steel plate and engaging a bolt and nut inserted from a buckling area bored on the surface of the panel by way of a presser plate. SOLUTION: A mounting metal fitting 6 bends a part of a steel plate in the shape of L, thereby forming an erected piece. Both ends of the steel plate are erected so as to oppose with the erected piece, thereby forming a header face contact piece. The mounting metal fitting 6 is mounted on the buckling area bored in a buried area of a reinforcing material 4 in a composite ALC panel P and the rear surface of the composite ALC panel P where a nut 6d is inserted into a bolt hole 11 and a bolt 7 is engaged with the nut 6d by way of a presser plate 8. The mounting metal fitting is fixed with a building skeleton 9 by means of a stopper member 13 inserted from a small clearance 6c so that the composite ALC panel P may be mounted thereon.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a thin ALC panel which is painted on a surface in advance and is suitable for a wooden house.

[0002]

2. Description of the Related Art Since ALC panels are lightweight and excellent in fire resistance, they have been actively applied not only to steel-frame constructions but also to outer walls of wooden houses in recent years. Further, at that time, a pre-coated ALC panel having the ALC panel surface painted in advance at a factory or the like is transported to a construction site, and is attached to a building frame at the construction site.

As the ALC panel for an outer wall of a wooden house as described above, a thin panel having a thickness of about 60 mm or less is often adopted from the viewpoint of weight and cost. On the other hand, as a structure for attaching the ALC panel to the building frame, a long anchor is welded to the cage type reinforcing bar in the panel and embedded in the ALC panel in advance, and a bolt is screwed to the anchor to attach a mounting bracket or the like. Generally, it is used to attach it to the skeleton, but the thickness as described above is 60
In the case of a thin ALC panel of about mm or less, since it is technically difficult to embed a cage reinforcing bar inside the panel, it is rare that anchors are buried in the panel in advance.

Therefore, in the case of such an ALC panel, a mounting bracket, a metal plate, or the like is provided on the back surface or the skeleton, and a bolt or the like is penetrated from the surface of the ALC panel to attach the ALC panel to the skeleton (Japanese Utility Model Laid-Open No. 2-112812; JP-A-63-171513, JP-A-6-62027, etc.) or the end of the ALC panel is gripped with variously shaped metal fittings such as L-shaped, Z-shaped, U-shaped and U-shaped. In general, a structure in which the metal fittings are attached to the frame with bolts, screws, screws, or the like is generally employed.

[0005]

However, Japanese Utility Model Application 2-1
In the mounting structure as disclosed in Japanese Patent No. 12812, when the panels are mounted at a predetermined position by abutting their small edges, if the fixing positions of the panels are not clear, the joint intervals of the panels may be uneven or a plurality of panels may be installed. When the panel is stuck in a predetermined area of a building, there is a drawback that its end part does not fit in a predetermined position. In addition, since the bolt head protrudes from the panel surface, the presence of the bolt head is not desirable in appearance, especially in the case of a panel that has been painted in advance for the outer wall, and there are problems with the appearance and the waterproofing of the bolt part. There is also a problem that it is practically difficult to apply the method to a pre-coated panel because a means for solving the problem is also required.

On the other hand, Japanese Utility Model Application Laid-Open No. Sho 63-171513,
As disclosed in Japanese Utility Model Application Laid-Open No. 6-62027, a structure in which a seat moat is formed on the panel surface, bolts and the like are penetrated from the surface side, and nuts are screwed into the bolts via a plate or the like on the rear surface side of the panel and attached. At the time of mounting, it is necessary to mount the panel while supporting the front side and the back side of the panel, so that there is a problem that the working efficiency is poor and that at least two people are required for the mounting work of one panel. Also, T-shaped or L-shaped brackets (angles, etc.) are required, and if you try to arrange multiple panels without using those brackets,
As described above, there are disadvantages in that the joint intervals become uneven and the panels do not fit within a predetermined area of the building.

Further, the end of the ALC panel is L-shaped, Z
Even in a structure in which the panel is gripped by mounting brackets such as a U-shape, a U-shape, and a U-shape, it is difficult to accurately and easily align joint joints when arranging panels. In addition, it is necessary to attach the mounting bracket to the building frame with bolts and screws,
In order to increase the mounting force of the screw or the like, it is necessary to increase the area around the screw hole of the metal fitting. Therefore, in most cases, the mounting portion of the conventional metal fitting projects to the rear surface of the panel, and the portion is mounted on a building such as a beam or a pillar. Therefore, in such a structure, it is necessary to mount the panel on the back side of the panel. As in Japanese Utility Model Laid-Open Publication No. 63-171513 and Japanese Utility Model Laid-Open Publication No. There is a problem that the work needs to be performed while supporting the side and the workability is poor.

In order to eliminate such a problem of the mounting workability, it is necessary to position the mounting portion of the mounting bracket at the joint portion and mount the mounting bracket to the building driving body from the surface of the panel. In order to drive the panel in, it is necessary to make the area around the screw hole of the metal fitting sufficiently large in view of the mounting strength of the panel, and therefore it is necessary to considerably increase the joint space between the panels. However, if the joint spacing is widened, the appearance is impaired and the sealing is difficult, so rain leaks and the like easily occur,
In addition, other problems such as cost and sealing workability arise.

Therefore, an object of the present invention is to solve the problem of A
Various problems of the conventional mounting structure when mounting a thin ALC panel which is an LC panel and in which an anchor is difficult to be embedded can be eliminated, and the panel end face can be accurately positioned at a predetermined position. It is an object of the present invention to provide an ALC panel mounting structure suitable for a wooden house having a minimum joint interval and capable of being mounted only from the front side of the panel at the time of mounting and having sufficient mounting strength.

[0010]

An object of the present invention is to provide an ALC panel mounting structure in which a surface is applied to an ALC panel provided with a mounting bracket, and the small side faces of the ALC panel are attached to a building frame by abutting each other. In the mounting bracket, one end of the steel plate is bent into an L-shape to form an upright piece, and a small face contact piece is formed so as to face the upright piece and form a small interval with the upright piece. A nut is erected and fixed at a predetermined position on the side where the fore-face abutment piece is provided and in a buried area of the reinforcing steel material inside the ALC panel. The mounting bracket is attached to the building frame by a stop member inserted from the small interval, and the ALC panel is a boring inserted from a dug portion dug on the surface side thereof. It engaged DOO and through the nut and the pressing plate threadedly achieved by mounting structure being clamped fixed.

The operation of the present invention will be described below. AL
The C panel has a mounting bracket attached to the back surface thereof, and is provided with a screw or the like from between a standing piece having one end bent and a small-face contacting piece formed so as to have a small gap therebetween. Therefore, when the ALC panel is attached to the building driving body, the ALC panel can be attached only from the surface side of the ALC panel, and the joint space between the ALC panels can be narrow and constant. In addition, the upright piece serves as an edge piece of the screw hole and can have a sufficient length, so that the tightening strength of the screw can be increased. Furthermore, since the standing piece can be arranged and attached to the driving body while the small face of the other ALC panel is in contact with the standing piece,
Panel arrangement and installation work become easy.

The small-face contact piece regulates the position of the small face of the ALC panel to which the mounting bracket is mounted, and the nut fixes the mounting bracket to the ALC panel.
Since the ALC panel is fixed so as to be located in the buried area of the reinforcing steel material inside the ALC panel, the ALC panel can be firmly attached without chipping the edges and corners. In other words, ALC panels have the disadvantage that, unlike other concrete materials, the strength is low, and the corners and edges are particularly easily chipped. It is important to locate the part.

[0013] Further, a seat moat is dug on the surface side of the ALC panel, a bolt is inserted from the inside thereof, and the mounting bracket is screwed to the bolt and the nut via a holding plate, so that the ALC panel is formed. Attach the mounting bracket to
Then, by filling the moat portion with the mortar or the like and then painting, it is possible to prevent the bolt head from protruding from the surface of the pre-painted ALC panel.

According to the second aspect of the present invention, since the ALC panel is bonded to the back side of the wooden board, the elasticity is remarkably improved, and the panel's resistance to wind pressure is greatly improved, and the thickness of the panel is 30 mm to 70 mm. Thin composite ALC
Since it is a panel, it is more suitable for wooden houses, and even with such a thin ALC panel, a thin composite ALC panel having a sufficient bending strength (wind pressure strength) can be obtained. Even a composite ALC panel, such as a thin metal plate, ceramic, gypsum board, etc., lacks elasticity, so that it is difficult to obtain high wind pressure resistance.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the ALC panel 1
The front surface is pre-painted in a factory to provide a coating layer 2, and a wooden board 3 such as a wooden plywood is bonded to the back surface with an adhesive to form a composite ALC panel P. The ALC panel 1 has a reinforcing steel member 4 such as a reinforcing bar or a lath net embedded therein, but does not have an anchor made of a nut or the like for mounting the panel. Further, each of the composite ALC panels P has a joint face 5 formed at a predetermined interval by abutment with each other, and is attached to a building driving body 7 made of a wooden pillar via a mounting bracket 6 described below. ing.

As shown in FIG. 2, the mounting bracket 6 has an upright piece 6a formed by bending a central portion of one end of a steel plate into an L shape.
Are formed, and both end portions of the steel plate are erected so as to be opposed to the upstanding piece 6a to form a fore-face contact piece 6b. As shown in FIG.
The small face of the composite ALC panel P abuts. The standing piece 6a and the fore-face contacting piece 6b are connected to each composite ALC panel P
A small space 6c is formed at a distance corresponding to the joint space therebetween, and a screw 13 is inserted from the small space 6c and driven into the building driving body 9.

Further, as shown in FIG.
A nut 6d is fixed upright on the side where the fore-face abutment piece 6b is provided and at a position far away from the fore-face abutment piece 6b, as shown in FIG. In the composite ALC panel P, the reinforcing steel material 4 is buried at a predetermined position in a buried area. The upright piece 6a and the fore-face abutment piece 6b do not need to be provided on the central portion and both sides of the steel plate as in the embodiment, and may be formed by bending each steel plate one half at a time. Although not shown, the screw hole of the nut 6d penetrates and the bottom of the steel plate is opened, so that not only the bolt 7 is screwed from the head side, but other bolts are also The structure is such that it can be screwed. With such a configuration, the panel can be attached to the driving body from the back surface of the attachment fitting 5, and the panel can be lifted and moved by a rope or the like, which is advantageous in the attachment work.

The mounting bracket 6 as described above is provided with a digging portion 10 dug in a region where the reinforcing steel material 4 is embedded in the composite ALC panel P.
Nut 6d is inserted into the bolt hole 11 and the nut 6
A bolt 8 is screwed to d via a holding plate 8 (washer) and attached to the back surface of the composite ALC panel P. The moat portion 12 is filled with a mortar 12, and the coating layer 2 is provided thereon. Then, the mounting bracket 6 is fixed to the building driving body 9 by the stopper member 13 (screw) inserted from the small interval 6c, and the composite ALC panel P is mounted. The joints between the composite ALC panels P are filled with a sealing material and a backup material.

ALC panel 1 according to the mounting structure of the present invention
Can be applied to a panel using only ALC, but it is more preferable that a wood-based board 3 such as plywood is joined to the back surface of the panel with an adhesive or the like from the viewpoint of improving bending (improving wind pressure resistance). The total thickness of the composite ALC panel P is 30 mm.
The thickness of the ALC panel 1 is in a range of from
60 mm thin, more preferably 35 mm to 5 in total thickness
A of 0 mm is excellent in fire resistance and heat retention.
While taking advantage of the features of LC panels, the weight is further improved, making them ideal for use as exterior walls in wooden houses.

Further, in the present invention, as shown in FIG. 1, a hat-type fixing bracket 14 as shown in FIG. 3 is attached to another building driving body 15 on the back surface of the thin composite ALC panel P. Is more preferable in terms of improving the mounting strength. That is, the hat-shaped fixing bracket 14 is
And a horizontal portion 14b and a claw portion 14c formed at the upper end thereof, and a screw is driven into the concave portion 14a from the front side of the panel, and is attached to the building driving body 15 from the back side of the panel. A screw is driven into the panel from the L-shaped metal piece 16 through the horizontal portion 14b. When formed as the concave portion 14a, the tip portion of the screw driven from the panel front side can be fixed without protruding outside the panel rear surface, and the horizontal portion 14b can be fixed to other fixing hardware on the panel rear surface side. Can be fixed to the screw,
The panel can be fixed from both sides by driving in bolts. Further, when the claw portion 14c is provided, the hat-type fixing bracket 14 can be fixed and prevented from rotating.

When the above-described mounting structure using the hat-type fixing bracket 14 is combined with the mounting structure of the present invention, even a wide panel can have sufficient strength, so that it is particularly wide such as for an outer wall of a wooden house. The effect becomes remarkable when applied to panel mounting. Although the ALC panel mounting structure of the present invention is most suitable for an outer wall of a wooden house, it can also be applied to other buildings such as a steel frame.

[0022]

According to the ALC panel mounting structure of the present invention, the following various effects can be obtained. Although it is a type of ALC panel in which the mounting anchor is not buried inside the panel, it can be easily mounted on a building driving body. Since the ALC panel is a kind of decorative panel whose surface has been painted in advance in a factory or the like, it can be mounted immediately without painting or processing at the construction site. Therefore, the finished surface is uniform and excellent. When the ALC panel is attached to the building driving body, the ALC panel can be attached only from the front side of the ALC panel, so that the number of attaching persons can be reduced and the efficiency of the attaching work can be increased. Since the joint space between ALC panels can be reduced, the appearance of the entire building is not impaired. When mounting the ALC panel, the arrangement is easy and the joint interval can be accurately located. Since the upstanding pieces serve as edge pieces of the screw holes, it is possible to increase the tightening strength of the screws. The ALC panel can be attached firmly without chipping off the edges or corners.
