Compared with the traditional concrete structure, the steel structure decorating beam has much smaller dead weight, can carry out hoisting work only by utilizing the on-site tower crane, and has small construction potential safety hazard by adopting integral hoisting to complete one-time installation.
4. The construction speed is high, multiple working procedures can be alternated for construction, and the construction period is saved;
and each main component of the steel structure decorating beam is finished in a steel structure processing plant in advance during the construction of the main structure, and the steel structure decorating beam can be hoisted after the concrete strength of the installed node reaches the design requirement. The construction progress and the main structure are synchronous or advanced, other working procedure construction is not influenced, the overall construction progress is quickened, and the overall construction period of projects is saved.
5. The measure cost is low, and the resources are saved.
Besides the hoisting safety measures, the construction measures of the steel structure decorating beam have no other measure cost, and the overall construction measure cost is low; the assembly construction is adopted on site, the assembly of the finished product can be completed only by 2 workers, and the hoisting process is completed only by 4-6 workers.
6. Green construction, energy conservation and environmental protection.
The construction method of the steel structure decorating beam with the large span of the outer vertical surface of the roof adopts the industrialized production technology and the on-site assembly construction mode, has high structure quality, low resource consumption, less environmental pollution and good economic benefit, and accords with the development concept of green construction and assembly construction in China.
