<p>The present invention relates to a connection structure of vertical exhaust pipes in a dry-type air duct system, and an objective of the present invention is to provide a connection structure of vertical exhaust pipes in a dry-type air duct system having a simple and sturdy structure while increasing the work efficiency and easily preventing the leakage of a connection portion. To achieve the objective, the connection structure of vertical exhaust pipes penetrating sleeves of each layer is improved to make the sleeves become integrated with the vertical exhaust pipes, and the integrated sleeves and vertical exhaust pipes are joined, using a ring-shaped thermal-fireproof sealing member using sleeve fixating bands and pipe supporting holes, thus fundamentally removing the fireproof block, which is a gap between the sleeves and the vertical exhaust pipes penetrating the sleeves, and reducing materials such as additional vertical exhaust pipes, refractory fillings and V-bands.</p> |
