Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an exterior wall panel mounting structure that can streamline the mounting of exterior wall panels placed outside beams.

[Conventional technology]

BACKGROUND ART In recent years, concrete exterior wall panels are often used to increase fire resistance and sound insulation when forming walls such as exterior walls of houses. Also, for such exterior wall panels,
In order to increase the living area and make effective use of the site, they are often placed outside, such as on beams.

[Problem to be solved by the invention]

However, such exterior wall panels, especially concrete panels made of concrete, are heavier than regular wall panels with side panels attached to the front and back of the framework, so it takes a lot of effort to attach them to the outside of beams, etc. In addition, there is a problem that the safety of the installation work and the accuracy of the installation are inferior.

Therefore, it is easy to install heavy exterior wall panels,
There has been a demand for a structure that can improve assembly accuracy and work safety.

The present invention is based on interposing a connecting plate having an overhanging part that projects outdoors between the connecting piece of the upper and lower mounting brackets fixed to one side of the column and the beam material, and the external wall. The object of the present invention is to provide an exterior wall panel mounting structure that allows panels to be mounted accurately and efficiently.

[Means to solve the problem]

In order to achieve the above object, the exterior wall panel mounting structure of the present invention includes an upper mounting bracket having an upper connecting piece extending horizontally and perpendicularly to the one side, and a lower mounting bracket on one side of a column using a square steel pipe. The lower mounting brackets having connecting pieces are fixed vertically, and the upper surface of the beam member whose end is inserted between the upper connecting piece and the lower connecting piece and is perpendicular to the one side, and Connecting plates each having an overhang that protrudes toward the outdoors are interposed between the lower surface of the connecting piece and between the lower surface of the beam and the upper surface of the lower connecting piece, and the upper and lower connecting pieces are connected to the beam. At the same time, a support fitting for attaching an external wall panel arranged outside the beam is bolted to the overhang.

[Operation] A beam material is inserted between the connecting pieces of the upper and lower mounting brackets fixed to one side of the column, interposing a connecting plate that projects outdoors and has an overhang to which an external wall panel can be attached. death,
In addition, the upper and lower connecting pieces of the core are bolted to the beam material. Therefore, at the same time as the beam material is attached to the column, the connecting plate for attaching the outer wall panel can be bolted, and the number of work steps can be reduced.

Further, a support fitting for attaching the outer wall panel is bolted to the overhang. By bolting all the members for attaching the outer wall panel in this way, the outer wall panel can be attached with high precision and efficiency, and it also helps to improve safety by speeding up the work.
