Embodiment

[0034] In the following, a high-rise under construction is taken as an example to describe in detail how the invention reduces the vibration of the main structure under the action of an earthquake.

[0035] The building is a comprehensive super high-rise building integrating five-star hotels, shopping malls, and high-end office buildings. It is a core tube-concrete steel tube structure with 71 floors above ground and 6 floors underground, with a height of 318 meters. According to the plane area of ​​the core tube, the specifications of each component of the steel platform formwork system are determined to meet the requirements in the technical plan. Then, the construction steel platform formwork system with double tuning mass vibration damping function is attached to the core tube for construction. Whenever the core tube is built with 5 floors, the first-order natural vibration frequency of the main structure is measured. During the construction process, the entire steel platfo...

Abstract

The invention relates to a construction steel platform mould base system with a double tuned mass vibration reduction function. A fixing connection mode of a traditional whole climbing steel platform mould base system and a structure main body is transformed into a mode that the bottom connected to a friction support base can slide, tuning vibration reduction control is conducted by using the steel platform mould base system, and meanwhile the vibration of the structure main body and the mould base system generated by earthquakes or wind load is reduced. A friction swing support base is also arranged on a material stacking area platform, the mode of tuned mass vibration reduction is adopted to further reduce the vibration of the structure main body and the mould base system, accordingly, the whole platform system becomes a double tuned mass damper, and double tuned mass vibration reduction is achieved. The parameters such as support base rigidity and material stacking area platform quality mass are changed, so that the system is adapted to the structure frequency in different construction processes, and accordingly the better vibration reduction effect is achieved. The tuned mass vibration reduction function and the normal usage function of the steel platform mould base system can be switched at any time, and the system is flexible to use. The construction steel platform mould base system belongs to the technical field of wind resistance, shock resistance and shock absorption of civil engineering.

Description

technical field [0001] The invention relates to a construction steel platform formwork system with double tuned mass vibration damping functions, and the invention belongs to the technical field of wind resistance, earthquake resistance and shock absorption of civil engineering. Background technique [0002] In recent years, the height of high-rise and super high-rise buildings at home and abroad has continued to rise, and the shape of the buildings has become more and more complex, and there are more and more irregular structures, which are very unfavorable to the earthquake resistance of the structure. my country is located in an earthquake-prone area, and high-rise building anti-seismic fortification and wind resistance and vibration reduction are urgent tasks for engineering design. In order to ensure the anti-seismic and wind-resistant safety of high-rise structures and achieve the unity of safety and economy, it is necessary to improve the anti-vibration capacity of hi...
