Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rigid mounting structure for a floor or roof panel plate, and more particularly to a steel frame structure in which the floor or roof part is made of a panel plate such as an ALC plate. In order to secure horizontal rigidity with the ALC plate,
The present invention relates to a rigid mounting structure for a floor or roof panel plate in which an ALC plate and a beam are integrated.

[0002]

2. Description of the Related Art In general, a panel plate such as an ALC plate formed of foamed or lightweight concrete is laid on the roof or floor of a steel frame structure. In such laying, conventionally, as shown in FIG. 6, the ALC plate 2 is laid on the beam flange surface 3 with its ends aligned, and a mortar 4 is filled between the ALC plates 2 and 2. Further, a slab plate 5 is installed upright on the flange surface 3 at the corner portion 2A of the ALC plate 2, the joint slab 6 is inserted through the slab plate 5, and the joint rebar 6 is embedded in the mortar 4. Has become. Therefore,
The slab plate 5 and the joint reinforcing bars 6 maintain the mounting structure of the panel plate such as the roof or the floor.

Further, a rigid slab has been proposed in which a square metal fitting is used instead of the slab plate.
-9368). Such a support metal fitting is fixed to the beam flange surface, and the ALC plate is arranged by fitting the support metal fitting surface with the corner portions cut out. The support fitting is bolted to the joint rebar and prevents the ALC plate from coming into contact with its side wall surface. Therefore, the horizontal rigidity of the floor structure is increased by the fastening of the support metal fittings and the joint rebars and the immobilization of the ALC plate in the rectangular tube in the horizontal direction, and the buckling of the beam is prevented.

[0004]

However, in the conventional panel plate mounting structure shown in FIG. 6, the ALC plate cannot bear the in-plane rigidity, and a brace or the like is stretched between the beams to provide rigidity. I had to let him. For this reason, there is a problem that the ceiling is lowered due to the brace, and it becomes an obstacle to site work such as equipment piping and outer wall installation, resulting in an increase in cost. Further, although the rigidity can be maintained with the conventional supporting metal fittings, the rigidity due to the fastening of the ALC plates is not utilized, and there is room for further improvement.

Therefore, according to the present invention, the horizontal or rigid floor or roof panel is borne by the panel plate itself such as an ALC plate, and the panel or roof panel has sufficient rigidity even when blown up from the floor or the like. An object is to provide a rigid mounting structure for a plate.

DISCLOSURE OF THE INVENTION The present invention is a rigid mounting structure for a panel panel for a floor or a roof, which is constructed by laying a plurality of panel plates on a beam or the like, and is fixed to a predetermined position of the beam flange with bolts and nuts. A support metal fitting including a base plate and a standing member that is erected on the base plate is provided, and the laying panel has a corner portion cut out in accordance with the base plate of the support metal fitting, and the vicinity of the cutout portion. At a predetermined position inside the reinforcing bar of the panel plate, a columnar hole that is substantially vertical to the panel plate surface is formed, and a communication hole that substantially horizontally communicates between the side wall of the columnar hole and the standing member is formed. A cylindrical steel pipe is provided in the cylindrical hole, and a bolt for fastening the steel pipe and the standing member is provided in the communication hole to integrate the panel plate and the support fitting. Floor or By providing a rigid mounting structure for roofing panel board, it is obtained by achieving the above object.

[0007]

The panel plate is laid so as to be surrounded by a plurality of support fittings fixed to the beam, and the laid panel board is fastened to the support fitting through a steel pipe having a cylindrical hole, fastening bolts and standing members. Therefore, even when horizontal stress is generated in the entire building, the panel plate and the support fittings, the panel plate and the beams, and the panel plates are integrated with each other, and the panel plate having the reinforcing bars can bear the horizontal rigidity. Further, the panel plate can exhibit rigidity even when blown up from the floor or the like. Furthermore, since the member to which the fastening bolts are attached is a cylindrical steel pipe, when horizontal stress is applied to the panel plate, the stress transmitted from the bottle is dispersed by the cylindrical steel pipe wall, causing local destruction of the panel plate. It is hard to occur. Moreover, the cylindrical hole is provided inside the reinforcing bar, and the steel pipe is restricted by the reinforcing bar against the tension of the bolt.
Therefore, the rigid mounting structure of the floor or roof panel plate is endowed with strong rigidity.
