The construction steps of steel structure roof include the following steps:
(1) Before construction, the site investigation shall be carried out and the materials shall be prepared to create a good construction environment for the smooth construction of the installation personnel.
(2) Be familiar with the drawings, understand the design intent, and prepare detailed construction technology and technical safety measures.
(3) The fabrication and processing of steel members shall be carried out. The roof truss shall be fabricated separately in the processing plant, and then spliced and installed on site.
(4) For manual welding, start the installation of steel structure roof after correcting the steel column. Before hoisting, the whole roof truss should be spliced and hoisted by car.
(5) Roof support installation, after installing the roof truss, install the roof light steel purlin and roof panel.
The waterproof construction of steel structure roof mainly refers to the construction of steel structure roof waterproof system. The main constituent materials are base waterproof coating, surface waterproof coating and reinforced polyester cloth.
The waterproof system of steel structure roof can solve the water leakage problem of metal roof at one time, and has super tensile strength, UV resistance, aging resistance and softness resistance. At the same time, the waterproof system of steel structure roof is non-toxic, tasteless, non corrosive and stable in quality.
The waterproof system of steel structure roof can be used for horizontal lap and vertical lap of steel structure roof, air conditioning pipes, gutters, metal plates, etc. The waterproof of its detailed structure or weak links only needs to be constructed directly on the steel structure roof, without complex processes, and the service life is as long as 20 years, which is durable.
