DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an A
The present invention relates to an ALC panel weight receiving structure for mounting an LC panel to a steel frame and a metal fitting thereof.

[0002]

2. Description of the Related Art Conventionally, AL used for wall materials of buildings, etc.
As shown in FIG. 5, the C panel has a reinforcing net 1 on two surfaces, which is composed of a main bar 1 a and a sub bar 1 b, embedded in an ALC panel 2. As shown in FIG. 6, the ALC panel 2 is attached to a weight receiving member 4 attached to a frame 3 by a lower front surface 2 thereof.
a is supported and attached to the skeleton 3 by the mounting bracket 6. As shown in FIG. 7A, the weight receiving member 4 includes a receiving portion 4a having a horizontal surface and a connecting portion 4b formed vertically below the receiving portion 4a. 4a is the lower edge 2a of the ALC panel 2
It is supported in contact with the whole.

[0003]

However, in the above structure, the weight receiving fixture 4 is deformed as shown in FIG.
The ALC panel 2 receives stress concentration from the receiving portion 4a and cracks k.
Often occurred. Therefore, the present invention provides a weight receiving structure and a metal fitting that can prevent the occurrence of cracks in the ALC panel 2 due to stress concentration.

[0004]

According to the present invention, there is provided an ALC panel weight receiving structure in which two reinforcing nets are embedded in parallel with the panel surface.
An ALC panel weight receiving structure for supporting a lower edge face of an LC panel in contact with a weight receiving part connected to a skeleton, wherein the receiving part is at least adjacent to the skeleton side edge of the lower edge face. It is characterized in that it does not come into contact with the surface up to the reinforcing net.

[0005] A weight receiving device for an ALC panel according to the present invention is a weight receiving device for an ALC panel which supports a lower edge surface of an ALC panel in which two reinforcing nets are embedded in parallel with the panel surface. And a receiving part, when connecting the connecting part to the frame and supporting the receiving part in contact with the lower foreface,
A non-contact portion is provided in the receiving portion so that the receiving portion does not come into contact with at least a surface of the lower fore surface from a side edge of the skeleton to a reinforcing net burying position adjacent thereto. It is.

[0006]

According to the present invention, the weight receiving member has the receiving portion and the connecting portion, and the receiving portion is provided with the non-contact portion. By applying the stress from the weight support to the stronger reinforcing portion sandwiched between the nets, it is possible to effectively prevent the occurrence of cracks due to local stress due to its own weight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1A is a partial cross-sectional view showing a weight receiving structure of the ALC panel of the present invention, and FIG. 1B is an enlarged view thereof. In FIG. 1, 1 is a reinforcing net, 2 is an ALC
Panels, 3 is a frame, and 5 is a weight bracket.

The reinforcing net 1 is composed of two surfaces, the front side and the back side of the panel, and is embedded in the ALC panel 2 in parallel with the panel surface. The reinforcing net 1 may use, for example, a reinforcing bar or a lath net. The figure shows the main bar 1a using rebar
It is an example of a reinforcing net 1 in which the reinforcing bars 1b are assembled by welding or the like. The ALC panel 2 has a beveled panel edge. The frame 3 is made of a steel frame, and the weight receiving member 5 is attached by welding or the like.

The weight receiving member 5 has a receiving portion 5a and a connecting portion 5b, and the receiving portion 5a has a non-contact portion 5c. (An enlarged view of the weight receiving member 5 is shown in FIG. 2.) The non-contact portion 5 of the receiving portion 5a
The horizontal surface other than c is the lower edge surface 2a of the ALC panel 2.
To support the ALC panel 2. The length of the portion where the receiving portion 5a and the lower edge 2a are in contact with each other is preferably equal to the distance between the two reinforcing nets 1, but may be less than that. May be extended.

The non-contact portion 5c is formed by a step provided on the receiving portion 5a. The step is a boundary between the contact surface and the non-contact surface, and the shape may be a right angle, an arc, a taper, or the like. The length of the non-contact portion 5c is preferably from the side edge of the skeleton 3 to the embedded position of the reinforcing net 1, and may be from the inside of the reinforcing net 1. The connecting portion 5b is formed to hang down from the receiving portion 5a and is parallel to the frame 3,
For example, it is attached by welding.

The weight receiving member 5 of the present invention has a connecting portion 5b.
Is attached to the frame 3 by welding or the like. Then, at least the reinforcing bar 1 does not come into contact with the buried position of the reinforcing bar 1 in the ALC panel 2 adjacent to the side edge of the skeleton 3.
Supports the lower fore-face 2a. ALC panel 2
Is attached to the skeleton 3 by an attachment (not shown). In addition, the part which contacts the connection part 5b of the weight support 5 on the upper side of the ALC panel 2 is notched in order to avoid the connection part 5b.

With such a structure, even if the skeleton 3 is deformed by the weight of the ALC panel 2, the stress does not concentrate on the weak portion of the ALC panel 2, so that the stress acts on the ALC panel 2 to generate a crack k. It becomes difficult to do. FIG. 3 shows another embodiment of the weight bracket. This weight bracket 5
Is the lower edge 2a of the ALC panel 2 in which the reinforcing net 1 is embedded.
And a non-contact portion 5c provided with a step so that a part of the reception portion 5a does not contact the lower edge surface 2a, and an upper right angle from the non-contact portion 5c along the surface on the panel frame side. And a connecting portion 5b connected to the skeleton 3 formed at the same time.

Further, conventionally, as shown in FIG. 8, the ALC panel 2 is not parallel to the weight support 4 due to deformation of the frame 3 due to an earthquake or the like. Then, the stress is concentrated on the weak portion of the ALC panel 2 by the weight receiving member 4, and the stress acts on the ALC panel 2 to generate a crack k. In such a case, however, the ALC panel 2 is provided on the ALC panel 2 even if the horizontal frame 3 is deformed due to an earthquake or the like by providing a downward slope at both ends of the receiving portion 5a of the weight receiving member 5 and chamfering the ends. A configuration in which cracks k are unlikely to occur can be provided.

The weight fitting 5 shown in FIG. 4 has a structure that exhibits an effect even in such a case. FIG.
5, the weight receiving member 5 has a receiving portion 5a and a connecting portion 5b, and the receiving portion 5a has a non-contact portion 5c. Further, the receiving portion 5a is provided with a downward slope 5d at both ends in the longitudinal direction. The connecting portion 5b is formed at a right angle upward from the non-contact portion 5c.

[0015]

The weight receiving device of the present invention has a receiving portion and a connecting portion, and a non-contact portion is provided in the receiving portion.
The portion where the lower edge of the panel is in contact is supported by a portion where the reinforcement is stronger between the reinforcing nets 1 on the two surfaces of the ALC panel, and the portion where the lower edge is weak is a non-contact portion. In addition, cracks are less likely to occur in the panel due to deformation of the bracket due to the weight of the ALC panel.

Also, as shown in FIG. 4, a non-contact portion is provided even if a displacement occurs in which the frame and the ALC panel are relatively inclined due to an earthquake or the like by providing a downward inclination at both ends in the longitudinal direction of the receiving portion. Therefore, it is possible to prevent the ALC panel from being damaged by an excessive force and causing a crack.
