Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel board screw mounting structure, and more particularly, to a horizontal structure in a steel frame structure in which a floor or roof portion is formed of a processed panel board such as an ALC plate. The present invention relates to a screwed mounting structure of a panel plate in which ALC plates and beams are integrated to secure rigidity in the ALC plate.

[0002]

2. Description of the Related Art Generally, a processed 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 71 is filled between the ALC plates 2 and 2. A slab plate 72 is installed upright on the flange surface 3 at the corner 2A of the ALC plate 2,
The joint rebar 73 is inserted through the slab plate 72, and the joint rebar 73 is embedded in the mortar 71. Therefore, the slab plate 72 and the joint rebar 73 prevent the roof or floor from moving or rising.

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 arranged by notching a corner portion of the ALC plate and fixing it to the beam flange surface. The support fitting is bolted to the joint rebar and prevents the ALC plate from coming into contact with its side wall surface. Therefore,
Regarding the horizontal rigidity of the floor structure, the strength of the floor structure is increased and the buckling of the beam material is prevented by fastening the support fittings to the joint rebar and immobilizing the ALC plate in the rectangular tube in the horizontal direction.

[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 the work on site such as facility piping and outer wall mounting is hindered, resulting in an increase in cost. Further, in the case of using the conventional supporting metal fittings, the rigidity can be maintained, but there is room for improvement in the rigidity by fastening the ALC plates to each other.

Therefore, according to the present invention, the horizontal rigidity of the floor or roof is borne by the panel plate itself such as the ALC plate, and the screw of the panel plate which maintains sufficient in-plane rigidity even when blown up from the floor or the like. It is intended to provide a combined mounting structure.

DISCLOSURE OF THE INVENTION The present invention is a panel board screw mounting structure in which a plurality of panel boards formed by concrete processing or the like are laid on a structural frame material such as a beam. A nut material formed in a shape and having a screw hole near the corner is embedded, and the nut material is provided so as to be screwed by the notch processing of the corner, and the nut material is screwed into the nut material. A bolt and a connecting metal fitting to which the connecting bolt is attached are arranged on the structural frame member in a space formed by the cutouts of the corners, and the connecting metal frame is mounted on the structural frame member. The above object is achieved by providing a threaded mounting structure for a panel plate, which is characterized by the following.

[0007]

When the processed panel plates are arranged and laid on a structural frame material such as a beam, the notches of the panel plates gather on the beam to form a rectangular void. The connection fitting is firmly attached to the space through a fastening material or the like, and the connection bolt is engaged. The bolt is screwed to the nut material embedded in the corner of the panel plate while being engaged with the connecting fitting. Therefore, the corners of the panel plates are attracted to the connecting fittings via the nut members, and the aligned panel plates adjacent to each other are tightly connected to each other. Further, the panel plate itself is fixed on the beam via a connecting metal fitting.

Therefore, the panel plates are integrated with each other and sufficiently resist the horizontal stress applied to the entire building. Further, in the case of a panel plate having reinforcing reinforcing bars and the like, the rigidity of the panel plates in the tightly bound state increases, and the floor and roof structures have sufficient horizontal rigidity. In addition, when the mortar is filled in the voids with such a structure, the bolts are firmly attached to each other, and the stability against the stress from the vertical direction due to the blowing of wind or the like increases.
