单层工业厂房结构安装施工方案38871（Single storey industrial building structure installation scheme 38871） A factory building, designed for single span single frame steel structure workshop, 41m long, about 6m, a total of 9 internodes, steel roof. The flat and cutaway drawings of the plant are shown in the diagram. The construction method of this project: the roof adopts 0.5mm thick W750 color profiled steel plate and edge wrapping angle, single ridge double slope drainage. The wall adopts sand lime brick masonry wall, reinforced concrete beams and columns. The main hoisting project is 16.6m steel roof truss, steel roof truss weighs 61.4KN, a total of 8, elevation 5.5m. Two. Preparation before structural installation (1) at the construction site of the factory, the hoisting parts should be put into place before lifting the components, the position of the supporting pad should be correct, and the position of the lifting point should be in line with the design requirements. (2) the site of pile components should be flat and solid. (3) when the component is in place, it should be laid on the cushion or bracket according to the force of the design, and should be kept stable. Three. Structure hoisting method After the steel roof truss is made in the factory, it is transported to the site by car. The roof system includes a roof, and roof purlin. The hoisting process of each component is as follows: Lashing - lifting - alignment - temporary fixing - correction - Final fixing Four. Selection of crane and calculation of working parameters The structure hoisting uses the automobile crane QY16 type, the hoisting main components work parameter is: roof truss Hoisting by two points lashing. Claim weight Q=Q1+Q2= (61.4+3.0) KN=64.4 KN The lifting height is shown in figure H=h1+h2+h3+h4= (5.5+0.3+2.7+3.0) m=11.5m Because the crane can be restricted to the hoisting position nearby, it is not necessary to check the lifting radius R. The steel roof in place after the need for multiple trial lifting
