Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a metal fitting for blocking a gap and applying a refractory material between an outer wall and a beam material arranged with a gap on the outer wall. Further, the present invention relates to a refractory base metal which can block the gap without performing a welding operation at a building site.

[Conventional technology]

2. Description of the Related Art In recent years, houses using a dry method using a panel body such as a wall panel and a floor panel have been increasing. Particularly, in the outer wall panel forming the outer wall of the house, a concrete material or the like is used to enhance fire resistance and heat insulation.

On the other hand, such concrete panels are often mounted outside the pillars in order to increase the living area and effectively use the site, and in such cases, the upper floors extend parallel to the outer walls along the outer walls from the pillars. A gap will be created between the supporting beam and the concrete panel.

On the other hand, in order to improve fire resistance, it is often used to apply a fire resistant material such as rock wool on the indoor side of the beam material.
When applying such a refractory material to the house, conventionally,
As shown in FIG. 9, a gap c between the beam member a and the concrete panel b is provided with a long base metal fitting d made of, for example, flat steel and substantially equal to the width of the concrete panel. To form a base of the refractory material e.

[Problems to be solved by the invention]

However, since the beam member a and the long base metal member d are fixed by welding as described above, a welding worker is required at the construction site, and it is not easy to secure the beam member and the construction period is delayed. In addition, when the base metal d is positioned so as to block the space c and is welded to the beam a, there is a problem that the work is troublesome and the construction efficiency is poor.

The present invention provides a method for welding at a construction site on the basis of attaching, via a hinge, a locking metal fitting to a projecting piece of the beam to a substrate capable of blocking a gap between the concrete panel and the beam. An object of the present invention is to provide a refractory base metal capable of eliminating work, improving workability and shortening a construction period.

[Means for solving the problem]

The present invention provides a concrete panel forming an outer wall of a house,
The gap between the concrete panel and a steel beam arranged in parallel with the concrete panel with a gap therebetween is blocked by supporting the concrete panel outward through a connection fitting, and a refractory material is applied. The refractory material base metal, the outer end of which is close to the inner surface of the concrete panel and the inner end of which is engaged with the projecting piece on the upper surface of the substrate located at the lower surface of the projecting piece at the lower end of the lower end of the beam material. Further, it is a refractory base metal member to which a locking member for keeping the substrate substantially horizontal is attached via a hinge.

(Operation)

The refractory base metal is a substrate whose outer end is close to the inner surface of the concrete panel and whose inner end is located on the lower surface of the projecting piece of the beam material.
It can be kept substantially horizontal by the locking metal fitting to the projecting piece.
Therefore, at the construction site, positioning and welding work for mounting the board can be eliminated, and construction efficiency is improved.

The board and the latch are connected via a hinge. Therefore, it is possible to mount the substrate on the beam in a state where the substrate is raised substantially vertically, it is possible to prevent interference between the substrate and the concrete panel, and it becomes easier to mount the refractory base metal.
