BIM technology meets the development trend of different architectural shapes in the future, reasonably integrates BIM technology with the existing cutting-edge technology and advanced equipment of steel structure, improves the precision, develops new ideas, innovative construction, and intelligent construction, which is conducive to promoting the construction industry flourishing.
The characteristics of steel structure construction are usually long construction period, large number of parts, complex manufacturing process and high design error. During the construction of the project, there are very strict requirements on the overall accuracy of the construction.
With the marketization of the economy, people pay more and more attention to the quality and appearance of buildings, and construction engineering enterprises are facing a severe test.
China's construction industry has developed rapidly in recent years, and at the same time, industry competition has become more and more fierce, the market environment has become more complex, the source of building construction materials has become wider, and the building structure has become more diversified.
Through the practice of different lifting schemes for three maintenance hangar space frames, this paper summarizes and extracts the scope of application and advantages and disadvantages of different hangar space frame lifting schemes, and proposes that the in-situ lifting space frame should be used first under the condition of technical strength.
The roof of the maintenance hangar often adopts a spherical space frame structure, and a multi-layer truss structure is used at the warehouse door. Construction requirements often have the characteristics of large span, high height, small deformation requirements, and difficult construction.
During the connection of the post-insert rods, all jacking support hydraulic cylinders should be locked, and the stability of the space frame support body should be continuously observed, and the deviation of the support elevation that occurred during the connection of the post-insert rods should be adjusted in time to avoid construction stress solidification.
Prepare the space frame jacking construction plan, determine the position of the space frame support points, and assemble and lift in stages.
A gymnasium is a Class B venue with 4,495 seats for spectators. It mainly undertakes competitions in martial arts, Sanda and gymnastics. The building area of the venue is 13844.66m2, and the building height is 25.86m. Square cone bolt ball double-layer ellipsoidal surface space frame structure.
High-altitude bulk loading adopts the form of steel structure tire frame platform, which cancels the traditional full-frame erection method and reduces the cost of scaffolding erection and maintenance.
space frame structure engineering as light steel structure will be more and more used to build large structural span buildings. As a result, construction management risks may arise during the installation and construction of the space frame structure, which should be given full attention by the supervising engineer.
The construction area of the flat roof steel space frame structure of an eastern coastal coal power plant is over 100,000 square meters, which is the first time for domestic coal-fired units to construct such a large-scale steel space frame construction and renovation project, and there is little similar construction experience to draw on. Therefore, it is of great importance to plan the installation of the roof space frame reasonably and choose a construction plan that is safe, efficient and economical and does not affect the normal operation of the coal yard.
