Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for mounting a concrete panel for a hanging wall, which allows the concrete panel for a hanging wall to be easily attached to a beam.

[Conventional technology]

Houses using the so-called panel construction method, in which the outer walls of the house are formed using concrete panels, are becoming popular.

Even in houses using such panel construction methods, concrete panels for hanging walls are sometimes used to meet the tastes of residents and to enhance the appearance. Such concrete panels are heavier than regular wall panels that have side panels attached to the front and back of the frame, but in recent years, concrete panels for hanging walls or exterior walls placed on the outward facing side of houses have become more expensive. In order to increase the living area and make effective use of the site, they are often placed on the outside of beams.

[Problem to be solved by the invention]

However, such concrete panels for hanging walls must be installed on the outside of the beams while aligning their outer surfaces below the concrete panels for external walls, making it difficult to install heavy concrete panels. I thought it was something.

Therefore, there has been a demand for a mounting structure that can efficiently mount concrete panels for hanging walls.

The present invention provides a support fitting for supporting a concrete panel for an external wall that is placed above a concrete panel for a hanging wall.
For hanging walls, concrete panels for hanging walls can be installed accurately and easily, based on the idea that the upper frame material is bolted to the inner surface and top of the concrete panel for hanging walls, and is bolted via connecting fittings. The purpose is to provide a mounting structure for concrete panels.

[Means to solve the problem]

In order to achieve the above object, the concrete panel mounting structure for hanging walls of the present invention is arranged along the outer surface of a beam made of I-shaped steel having upper and lower flanges, and is interrupted at the lower end, so that it can be attached to a house. An upper frame material made of channel steel is placed on the inner surface and above and below of the concrete panel for the hanging wall that forms the hanging wall.
The lower frame members are bolted together horizontally with their grooves facing each other, and the upper frame member is bolted to the upper flange, and a concrete panel for the outer wall is arranged above the concrete panel for the hanging wall. Bolt the lower frame material to the supporting metal fittings to be supported using connecting metal fittings, and
It is attached using a lower connecting fitting bolted to the lower flange.

[Effect]

The upper and lower frame members are bolted together on the inner surface of the concrete panel for a hanging wall, and the connecting metal fittings screwed onto the supporting metal fittings bolted to the upper and lower flanges of the beam material, respectively, and the lower connecting metal fittings. It is fastened with bolts. In this kind of construction, since all the parts are assembled by bolts, there is no special work process such as welding work, which improves the efficiency of the installation work and also improves the accuracy of the installation. Furthermore, the supporting metal fittings also support the concrete panel for the outer wall disposed above the concrete panel for the hanging wall.

Therefore, it becomes easy to install the concrete panels for hanging walls and exterior walls in a continuous manner vertically and with their outer surfaces aligned.
