Description

Description: TECHNICAL FIELD The present invention relates to an outer wall panel mounting structure capable of efficiently mounting an outer wall panel disposed outside a beam member.

[Conventional technology]

2. Description of the Related Art In recent years, concrete outer wall panels have been widely used to improve fire resistance and sound insulation when forming walls such as outer walls of houses. Moreover, in such an outer wall panel,
In order to increase the living area and effectively use the site, it is often placed outside such as beam materials.

[Problems to be Solved by the Invention]

However, since such an outer wall panel, particularly a concrete concrete panel, is heavier than a normal wall panel in which side plates are attached to the front and back of the frame, a great deal of time and effort is required for the work of attaching the beam material to the outside. In addition, there is a problem in that the safety of the mounting work and the mounting accuracy are poor.

Therefore, the work of attaching a heavy outer wall panel is facilitated,
There has been a demand for the appearance of a structure that can improve the assembly accuracy and work safety.

The present invention is based on the fact that a connecting plate having an overhanging portion that projects toward the outdoors is interposed between the connecting piece of the upper and lower mounting metal fittings fixed to one side surface of the pillar and the beam member, and the outer wall. It is an object of the present invention to provide an outer wall panel mounting structure capable of mounting a panel accurately and efficiently.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the outer wall panel mounting structure of the present invention comprises an upper mounting member having one side surface of a column using a square steel pipe and an upper connecting piece extending horizontally at right angles to the one side surface. Fixing the lower mounting bracket having the connecting piece of above and below, the upper end of the beam member having an end portion inserted between the upper connecting piece and the lower connecting piece and perpendicular to the one side surface, A connecting plate having a projecting portion projecting outdoors is interposed between the lower surface of the connecting piece and between the lower surface of the beam member and the upper surface of the lower connecting piece, and the upper and lower connecting pieces are connected to the beam. In addition to bolting to the material, a supporting metal fitting for mounting an outer wall panel disposed outside the beam material is bolted to the projecting portion.

[Action]

The beam member is inserted while interposing a coupling plate having an overhanging portion that projects outward and can be attached to the outer wall panel between the connecting pieces of the upper and lower mounting brackets fixed to one side surface of the pillar, and The upper and lower connecting pieces are bolted to the beam member.
Therefore, the joint plate for mounting the outer wall panel can be bolted at the same time when the beam member is mounted on the column, and the number of working steps can be reduced.

Further, a supporting metal fitting for mounting the outer wall panel is bolted to the projecting portion. By bolting all the members for mounting the outer wall panel in this manner, the outer wall panel can be mounted accurately and efficiently, and at the same time, the work can be speeded up and the safety can be improved.
