Description

Technical Field

[0001] The present invention relates to the technical field of building construction equipment, and in particular to an integrated platform system of a unit formwork and a placing machine suitable for vertical concrete structure construction of high-rise buildings / structures and a construction method thereof. Background Art

[0002] In the construction of super-high-rise buildings / structures over 250 meters in height using reinforced concrete core tube + steel structure outer frame or reinforced concrete core tube + giant column structure, large-scale full-function integrated formwork platforms have obvious construction advantages. However, for super-high-rise buildings / structures below 250 meters in height, their comprehensive advantages are greatly reduced. The core tubes of super-high-rise buildings / structures below 250 meters in height generally adopt a mode of synchronous construction of horizontal and vertical structures, which cannot provide working space for large-scale integrated formwork platforms. Therefore, the construction of buildings / structures below 250 meters in height mostly adopts relatively light formworks such as hydraulic climbing formwork or integral lifting scaffolding.

[0003] As a necessary means for the construction of super-high-rise buildings / structures, it is of great significance that the concrete placing boom can be integrated with the formwork platform. However, the load-bearing capacity of the overall lifting scaffolding not only cannot meet the requirements of integration with the concrete placing boom, but also cannot meet the needs of lifting with large formwork. The load-bearing capacity of the traditional hydraulic climbing formwork can meet the weight of a small concrete placing boom. However, setting the concrete placing boom on the top of the hydraulic climbing formwork will cause the formwork frame to shake periodically with the concrete placing boom during the concrete placing process, which will have a certain impact on the safety of the formwork frame. Therefore, it is necessary to develop a rationally constructed, safe and efficient integrated platform system of unit formwork and concrete placing boom. Summary of the invention
