Description

Description: TECHNICAL FIELD The present invention relates to a joint structure for a panel shutter, and more particularly to a water treatment structure for a joint portion of a panel shutter for preventing finger jamming.

[Problems to be Solved by Prior Art and Invention] Recently, a large span construction in which a roof of an air film structure is reinforced with a cable and air pressure is applied from the inside to keep the indoor side at a high pressure, and is supported by surrounding structures. The thing is called the air dome and is in the spotlight. As a result of repeated experiments and studies in selecting the opening / closing body that opens and closes the opening of the air dome, multiple panels are independent and each adjacent panel in the closed position is placed on the lower panel. It turned out that a panel shutter that takes a serial posture is suitable. However, the conventional panel shutter cannot be used as it is under various bad conditions such as the large pressure receiving area due to the large opening and the versatility and versatility of the user. We also needed to solve the problem.

[Means for Solving the Problem] The technical means adopted by the present invention for solving the above-mentioned problems is a step due to a rising piece provided at the upper edge of the panel in a closed posture of a panel shutter composed of a plurality of panels. Between the facing surfaces of the upper and lower panels where the part is formed, together with forming a joint portion for preventing finger stuffing that is opposed to and separated from each other at a predetermined interval so that the rising piece is located on the outdoor side, and is lower than the joint portion. In the longitudinal direction of the upper surface of the panel,
By forming a wall surface portion that prevents rainwater and the like from entering the indoor side, the groove-like portion formed by the rising and the wall surface portion, a closing member that closes both side edges thereof and a drainage channel communicating with the outdoor side. Is provided to form a gutter for rainwater drainage.

[Operation] Even though the joint has a stepped joint structure in which the upper edge of the panel of the joint facing the outdoor side faces downward, the joint does not impair the finger-filling prevention function and rainwater etc. can be prevented from entering. Even if there is, it can be prevented from flowing into the indoor side and the guide rail side through the step portion lower than the joint portion. The water, which is prevented from entering, can be drained to the outdoor side by using the groove portion as a gutter without accumulating in the groove portion formed in the longitudinal direction of the panel upper surface.
