Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel mounting hardware for a wooden beam, and in particular, a roof panel such as an ALC panel or a floor panel is laid on the upper surface of a wooden beam of a building and is used for the roof panel or floor. The present invention relates to a panel mounting hardware for a wooden beam, which allows a panel to be easily fixed to the wooden beam by a dry method.

[0002]

2. Description of the Related Art In recent years, there has been an increasing number of buildings in which roof panels or floor panels such as ALC panels are laid on the upper surface of wooden beams instead of steel beams to form roofs or floors. In such a building, how to easily fix the roof panel or floor panel to the wooden beam is an important issue.

[0003] Conventionally, as this type of technology, there is JP-B-3-1922 as an example of a wet method and JP-A-4-231536 as an example of a dry method.

Here, in the technique described in Japanese Utility Model Publication No. 1922, in fixing a roof panel or a floor panel to a steel beam, the lower part of the roof is welded and fixed to the steel beam. Considering that welding fixation is impossible in the case of a wooden beam, the rod having an annular portion is a threaded Malkan, the Malcan with the screw is screwed into the wooden beam, and a joint rebar is inserted into the Malcan. In this technique, the roof panel or the floor panel laid on the wooden beam is embedded in the joint portion, the joint portion is filled with mortar, and the roof panel or the floor panel is fixed to the wooden beam.

On the other hand, in the technique described in Japanese Patent Laid-Open No. 4-231536, a plurality of roof panels or floor panels laid on a beam are provided at the corners of the outer row panels. Fixed to the beam using a one-corner mounting hardware having an upper surface abutting portion that abuts the upper surface and a small edge surface abutting portion that abuts the corner edge surface of the panel, and the connecting portion between two adjacent panels in the outer row In the above, in the upper surface abutting portion that abuts the corner upper surfaces of the two panels, the edge abutting portion that abuts the corner edge surface of the two panels, and the facing edge surface of the two panels. It is fixed to the beam using two-corner mounting hardware having an insertion portion inserted between them, and further, in the connection portion of four adjacent panels in the inner row, each of them is attached to the upper surface of the corner portion of the four panels. Inserted parts that are respectively inserted between the abutting upper surface abutting part and the facing edge faces of the four panels. It is fixed to the beam using the four-corner mounting hardware having the above.The one-corner mounting hardware, the two-corner mounting hardware, and the four-corner mounting hardware are fixed to the beam by using a fixing tool such as a nail or a bolt. is there.

[0006]

However, here,
First, in the technique of Japanese Utility Model Publication No. 3-1922 described above, since it is a wet method of filling and fixing the mortar in the joints between the panels, the filling work of the mortar becomes complicated, and the filling mortar is cured. Therefore, there was a problem that the construction period would be prolonged. In addition, there was also a problem that the site gets dirty during the mortar filling work.

Further, the technique described in Japanese Patent Laid-Open No. 4-231536 does not have the disadvantage of the above-mentioned wet process because it is a dry process, but basically, the technique does not allow the four corners of each panel to be attached to the mounting metal parts. By pinching between the top contact part and the beam, and between the small face contact parts of the mounting hardware or between the insertion parts, the panel is prevented from moving in the vertical, horizontal, and front-back directions, and the panel is fixed to the beam. As described above, three types of mounting hardware (one-corner mounting hardware, two-corner mounting hardware, and four-corner mounting hardware) are required depending on the fixing part of the panel. Since fixing is also performed using a fixture such as a nail or bolt,
There are problems that the number of parts required for fixing the panel is large and that the mounting workability is poor. Further, in the technique described in Japanese Patent Laid-Open No. 4-231536, since the insertion portion of the mounting hardware is inserted not only between the short side edges of the laid panel, but also between the long side edges. There is also a problem that at least a gap is formed between the panels by the thickness of the insertion portion of the metal fitting, and the heat insulation and sound insulation of the formed roof or floor deteriorate.

The present invention has been made in view of the problems of the above-mentioned conventional techniques, and an object thereof is to provide a mounting metal article which can easily fix a panel to a wooden beam by a dry method. .

[0009]

In order to achieve the above-mentioned object, the present invention provides an upper surface abutting portion that abuts an upper surface of a panel laid on a wooden beam and a small edge surface of the panel laid on the wooden beam. A front face contacting portion, and at least one or more claws driven into the upper surface of the panel laid on the wooden beam are formed in the upper face contacting portion, and the front face contacting portion In the lower part of the above, a panel mounting hardware for a wooden beam is formed, in which at least two or more downwardly extending projections that are driven into the wooden beam having a sharp tip are formed.

When the panel is fixed to the wooden beam using the above-described mounting hardware according to the present invention, for example, the present invention is provided in the center portion in the width direction of the two short sides of the panel laid on the wooden beam. The mounting hardware according to the above is arranged such that the upper surface abutting portion of the mounting hardware is located above the upper surface of the panel, and the forefront surface abutting portion is in contact with the forehead surface of the panel. When hit from above, the upper surface abutting portion abuts the upper surface of the panel in a state in which one or more claws formed on the upper surface abutting portion of the mounting hardware bite into the upper surface of the panel, and It is possible to fix the panel on the wooden beam in a state where two or more protrusions having sharp tips formed in the lower portion are driven into the wooden beam and the panel is prevented from moving in the vertical, horizontal, and front-back directions.
