Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is capable of adjusting the amount of concrete panels arranged on the outer surface of a beam material without having to perform welding work at the construction site, thereby enabling the construction site to be adjusted. The present invention relates to a concrete panel support structure for improving construction efficiency and improving work safety.

[Conventional technology]

2. Description of the Related Art In recent years, concrete wall panels are frequently used for outer walls, partition walls, and the like in order to improve fire resistance and sound insulation of houses.

Such a concrete panel is heavier than a normal wall panel in which side plates are attached to the front and back of the framework and the inside and outside of the wall can be formed at the same time. For example, as shown in FIG.
The receiving member a supporting the lower end of the concrete panel P is connected to the beam member h.
The concrete panel P is fixed at a predetermined position outside the beam member h by being fixed on the upper side through an arm piece b.

[Problem to be Solved by the Invention] However, since the receiving device a needs to be adjusted to the entrance and exit of the concrete panel p and fixed to the beam member h when the concrete panel p is built, conventionally, the receiving device a and the beam The attachment of the material h has been performed by welding work at the site where the concrete panel p is to be built. Therefore, it takes time to install it, and it is necessary to secure welding workers only for this work, and it takes time to set up such as securing work personnel,
The construction period tends to be delayed. In addition, since fire is used in the welding operation, there is a problem in fire prevention.

Moreover, since the receiving member a attached by welding is permanently fixed, it is difficult to correct its position, and the correction requires time and effort.

A method of fixing the receiving member a to the beam member h using bolts is also conceivable, but in the case of bolt connection, the bolts must be loosened when adjusting the ingress and egress of the concrete panel p. The movement of the tool a involves a danger of work.

The present invention is based on the fact that two screw shafts protruding from a receiving fitting are fixed to nuts at different contact positions with two supporting fittings installed on a beam material, thereby facilitating adjustment of a concrete panel in / out position. An object of the present invention is to provide a concrete panel support structure capable of fixing concrete panels without performing welding work at the construction site, improving fire prevention and safety, and improving construction efficiency at the construction site.

[Means for solving the problem]

The present invention provides an inner and outer mounting fixture comprising a bottom plate fixed to an upper surface of a beam member on which a concrete panel is disposed on an outer surface, and two supporting members having two inner and outer supporting pieces parallel and perpendicular to the beam member. Concentric through-holes are respectively formed in the support pieces, and two screw shafts projecting inward from the metal fittings that receive the lower surface of the concrete panel are loosely fitted into the through-holes of the support pieces, respectively. A nut screwed into one screw shaft and between the inner and outer support pieces is brought into contact with the inner surface of the outer support piece, and a nut screwed into the other screw shaft between the inner and outer support pieces is placed inside the outer surface of the support piece. This is a support structure for a concrete panel brought into contact.

[Action]

The one screw shaft is prevented from moving outside the concrete panel because the nut is screwed to one of the screw shafts in contact with the inner surface of the outer support piece. In addition, the nut in contact with the outer surface of the inner support piece is screwed to the other screw shaft to prevent the concrete panel from moving inward. In this way, the two support brackets penetrate the screw shaft by changing the contact position of the nut, thereby preventing the concrete panel from moving in and out of the concrete panel, and furthermore, by screwing and retreating both nuts in the same direction. The concrete panel can be slightly moved in and out of the concrete panel, so that the concrete panel can be easily positioned.

Furthermore, since it is not necessary to weld the metal fittings at the construction site after the positioning of the concrete panel, welding work on site can be omitted, work efficiency can be improved, and safety can be improved.
