Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure of a panel shutter, and more particularly to a panel structure of a panel shutter device used to close a large opening.

[0002]

2. Description of the Related Art A panel shutter is formed by connecting roller shafts projecting from upper and lower side surfaces of a plurality of panels with connecting chains to form a shutter curtain. The extra length is engaged with a sprocket arranged near the storage rail provided in the front-rear direction of the left and right brackets arranged at the upper end of the guide rail erected on both sides of the opening of the building, and suspended. The opening is opened and closed by lifting or suspending the shutter curtain in conjunction with the forward and reverse rotation of the sprocket, and a plurality of panels are vertically open. And are connected so as to be stacked in a closed posture.

Conventionally, a panel used for such a panel shutter has a surface plate formed of a steel plate and is filled with a sound insulating material or the like, but the panel shutter is installed in a large opening. Panel width,
For example, when the heights have dimensions of about 10 m and 1 m, respectively, the weight of the panel becomes considerable, and a large load is applied to the switchgear and the connecting chain. Further, the panel itself cannot withstand its own weight and is bent downward.

The applicant has proposed a panel body made of a plate material using glass fiber reinforced plastic in Japanese Patent Application Laid-Open No. Hei 8-21019 in order to ensure soundproofing. This panel is excellent in soundproofing. There is a problem in strength in adopting it for a panel shutter installed in a large opening.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a panel which can reduce the weight of the entire panel, but is excellent in strength and sound insulation. The panel shutter can be installed in an opening having a width.

[0006]

The technical means adopted by the present invention to solve the above problem is to form a rectangular four-sided frame from a short left and right vertical frame and a long upper and lower horizontal frame. At the same time, a reinforcing frame was formed by connecting the upper and lower horizontal frames with a plurality of vertical rails at predetermined intervals in the length direction, and a surface material made of FRP was attached to both sides of the four-peripheral frame. It is characterized by:

With this configuration, the reinforcing frame bears the surface pressure and vertical force acting on the panel, so that a large panel that can withstand actual use can be configured. Also, since the bending moment acts on the joint of the reinforcing frame, the entire frame may be distorted by the vertical load. Since a part of the force in the direction is borne, the reinforcing frame and the FRP cooperate to reinforce the panel.

Preferably, the vertical dimension of the panel in the thickness direction of the panel is smaller than the vertical dimension of the vertical frame and the horizontal frame constituting the four-peripheral frame in the thickness direction. A predetermined gap is formed between the beam and the bar. Usually, in order to ensure good sound insulation performance, the hollow portion is filled with sound insulation material such as glass wool, but since a predetermined gap is formed between the surface material and the vertical rail, While a panel is formed by attaching a surface material to the reinforcing frame, sound from one side is not transmitted to the other side via the vertical rail.

When the left and right vertical frames are made of steel and the upper and lower horizontal frames and vertical rails are made of aluminum, the weight of the entire panel can be reduced by reducing the weight of the reinforcing frame. In addition, it is possible to provide a panel which has strength enough to be installed in a large opening and does not impose a load on a switchgear or a connection chain. In order to reduce the weight of the panel, the entire reinforcing frame may be made of aluminum. However, since the panel is suspended at the left and right ends, a considerable load is applied to the left and right ends. Is preferably formed of steel.
