BLOCKADING DEVICE OF SPACE BETWEEN ADJACENT ROOF MEMBERS IN OPENING AND SHUTTING ROOF

摘要

PURPOSE:To make sure to blockade a space by providing air bags provided with steel plates on the tip to one end of adjacent roof members piling up the ends through a space to expand when the surface of a roof is shut and, at the same time, attracting the steel plates by electromagnets on the other end. CONSTITUTION:When the surface of a roof is shut, roof members 1 and 2 adjoining and piling up through a space H are formed. After that, unit air-bags 3a are piled up to the end edge of the lower roof 1 to fix a bellows type unit 3 having steel plates 4 on the tip. Then, air-hoses 6 branched from air pipings 5 are connected to each of the unit bags 3a. In addition, electromagnets 8 are loaded to the end edge of the upper roof 2 in correspondence with the bags 3a. When the surface of the roof is shut, if the space H is blockaded, pressure- air is simultaneously enclosed into each of the air-bags 3a to expand, and the steel plates 4 are attracted and fixed by the electromagnets 8. According to the constitution, even if the space is changeable, blockade can be made with quick, position and high proof strength.
