Description

Shutter slat

The present invention relates to a shutter slat and more particularly to a slat for a shutter, in which a front and a rear member are separated from a front and a rear member by removing a partition wall, which is a two-ply slat connection portion constituting a shutter, So as to prevent warm air and cool air from being introduced from the outside into the room.

A shutter equipped with a shaft is installed in a building such as an airplane hangar, a power plant, a factory, a plant, and the like. Such a shutter serves to open or close an entrance of a building or a facility, And the door is opened or closed by raising or lowering the shutter, that is, raising or lowering the shutter.

Specifically, the above-described shutter is structured such that the slats made of aluminum or the like are continuously vertically combined and lifted or lowered while being wound or unwound on a shaft mounted on a shutter box on the upper portion of the guide rail, thereby opening or closing the shutter .

The shutter may include a plurality of narrow and long slats, a driving motor provided close to one side of the slats to provide a driving force for raising and lowering the slats, and a motor connected electrically to the driving motor, A switch box provided with an operation switch for reverse rotation, a guide rail formed vertically along both side edges of the slat and guiding the upward and downward movement of the slat, And a shaft to be lowered.

In the case of such a shutter, a heat insulating material is inserted into the slat for keeping the interior of the building warm during the winter season, or a separate heat insulating means is provided on the outer surface to prevent the cold wind from entering the room from the outside.

However, it is extremely difficult to insert and fix the insulator in the inner space of the slat so as to be completely filled, and there is a problem that the process cost is increased. In order to solve this problem, there has been developed a technique of foaming and molding an insulation material in a slat, but it is impossible to securely fill the space inside the insulation, and heat is transmitted through the slat panel in both the insulation- The problem of fundamental heat loss can not be solved.

However, in the case of the winter season, the cold air is transferred to the rear member through the connection portion by the heat conduction on the front member in the case of the summer season, and the transferred cold air and warm air are directly transferred to the room, There was a problem of wasting rain. During the winter season, condensation occurred on the slats located in the indoor direction, causing many problems.
