Hoisting steps of steel space frame structure

     The connection point of the steel space frame structure is a key step to connect the components of the junction and transmit the load. The development of an effective connection point design plan is crucial to the safety factor of the steel space frame structure, the production and installation, the construction schedule and the project budget. Immediate hazard. The connection points of the space frame are divided into internal connection points and rubber bearing connection points. The design plan and structure should comply with the requirements of effective support, reliable force transmission, simple structure, and convenient manufacturing and installation. Frame connection points are divided into several categories, each of which is electric welded thick steel plate connection point, electric welded hollow ball connection point, anchor bolt ball connection point, immediate intersecting connection point and welded pipe connection point.

The lifting steps of the steel space frame:

     1. Side-by-side high and low-span roof hoisting: be sure to install the high-span first and then the low-span, which is beneficial to the flatness of the high- and low-span steel beams.

     2. Side-by-side installation of large span and small span: be sure to install the large span first, and then install the small span. To

     3. Installations with larger side-by-side rooms and fewer rooms: first hoist the larger room, and then hoist the smaller room. To

     4. Hoisting of prefabricated components under most engineering construction conditions, the longitudinal prefabricated components are hoisted first, and then the plan view prefabricated components are hoisted, that is, the comprehensive installation method is selected for lifting. The layout of the hoisting machine and the line of operation of the space frame: the installation of the space frame should integrate the structural characteristics of the project, site conditions, and the working half of the crane on the spot, and carry out the layout of the hoisting machinery and equipment and the line of operation beforehand. The overall planning of the crane makes full use of the high efficiency of the crane to ensure the orderly development of the lifting.
