Description

Description: TECHNICAL FIELD The present invention relates to a mounting structure for a concrete panel for a hanging wall, which allows a concrete panel for a hanging wall to be easily mounted on a beam member.

[Conventional technology]

Houses of so-called panel construction method, in which the outer wall of the house is formed using concrete panels, are widespread. Even in a house having such a panel construction method, a concrete panel for a hanging wall may be used in order to meet the preference of a resident and to improve the appearance. Such concrete panels are
It is heavier than a normal wall panel with side plates attached to the front and back of the frame, but in recent years, the living area has increased in concrete panels for vertical walls or outer walls that are placed on the outward surface of a house. , In order to measure the effective use of the site, it is often placed outside the beam.

[Problems to be Solved by the Invention]

However, such a concrete panel for a hanging wall needs to be attached below and outside the beam panel fixing the lower end of the concrete panel for an outer wall to the lower side of the concrete panel for an outer wall, which is heavy in weight. Installation of concrete panels was difficult.

Therefore, there has been a demand for the appearance of a mounting structure capable of mounting concrete panels for hanging walls with good construction efficiency.

The present invention relates to a support metal fitting for supporting a concrete panel for an outer wall arranged above a concrete panel for a vertical wall, an upper frame member bolted to an inner surface and an upper portion of the concrete panel for a vertical wall, and a connecting metal fitting. It is an object of the present invention to provide a mounting structure for a concrete panel for a hanging wall, which is capable of accurately and easily mounting a concrete panel for a hanging wall on the basis of bolting via.

[Means for solving the problem]

To achieve the above object, the mounting structure for a concrete panel for a hanging wall according to the present invention has upper and lower flanges.
An upper frame member made of channel steel, which is arranged along the outer surface of the beam using the shape steel, and which is formed on the inner surface of the concrete panel for the vertical wall that forms the vertical wall of the house by being interrupted at the lower end and vertically.
Along with bolting the lower frame material horizontally and facing the groove portion, to the support metal fittings for supporting the outer wall concrete panel bolted to the upper flange and arranged above the concrete panel for the hanging wall, The upper frame member is connected through a connecting metal fitting including a fixing piece whose upper portion is bolted to the front surface of the supporting metal fitting and whose lower end is located below the upper flange, and a projecting piece projecting to the outdoor side located at the lower end of the fixing piece. Is fixed, and the lower frame member is attached via a lower connecting fitting having a fixing piece bolted to the lower flange and a hanging piece hanging from the fixing piece.

[Action]

The inner frame of the concrete panel for the hanging wall and the upper and lower frame members that are bolted up and down are connected to the supporting brackets that are bolted to the upper and lower flanges of the beam member, respectively. It is bolted using. In such construction, since all the bolts are assembled, there is no special work process such as welding work, the efficiency of the mounting work can be improved, and the mounting accuracy can be increased. Further, the support fitting also supports a concrete panel for outer wall arranged above the concrete panel for vertical wall. Therefore,
It becomes easy to make the concrete panels for the hanging wall and the outer wall continuous with each other in the vertical direction and to evenly attach the outer surfaces thereof. Also, since the upper frame member is fixed via the connecting metal fitting whose lower end is located below the upper flange,
The vertical wall located below the upper piece of the beam can be securely attached.
