Super high-rise core tube horizontal direction and vertical direction synchronous construction top formwork system and construction method

Abstract

The invention discloses a super high-rise core tube horizontal direction and vertical direction synchronous construction top formwork system which comprises a truss platform system, a hanger enclosure system, a supporting system, a formwork system and a hydraulic control system. The formwork system is an aluminum alloy formwork system. The aluminum alloy formwork system comprises vertical wall formworks and horizontal formworks. Each vertical wall formwork comprises a plurality of aluminum alloy standard unit plates spliced transversely, and C-shaped aluminum alloy grooves located in the aluminum alloy standard unit plates. Each horizontal formwork is formed by splicing a plurality of aluminum alloy bulk slicing plates. The horizontal formworks on the different layers are formed by splicing the aluminum alloy bulk slicing plates different in quantity. The horizontal formworks are connected with the vertical wall formworks through the C-shaped aluminum alloy grooves. According to the super high-rise core tube horizontal direction and vertical direction synchronous construction top formwork system provided by the invention, synchronous construction of horizontal structures and vertical structures of a core tube is achieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a top form system and a construction method for synchronous horizontal and vertical construction of a super high-rise core tube. Background technique [0002] At present, all "steel frame + concrete core tube" super high-rise structures under construction in China adopt the core tube first, and the outer frame steel columns, steel beams, and composite floors (or steel truss floor decks) are constructed after the "synchronous construction of different heights". Ascending" construction organization form, the core tube continues to lead the construction pace of the outer frame structure of the tower by about 10 to 15 floors. In the selection of core tube construction technology, since the construction technology of top formwork has been innovated in many links compared with climbing formwork and lifting formwork, it caters to the development of complex shape changes, rising heights, dive...

Problems solved by technology

[0003] However, in the currently widely used top formwork technology, the construction organization form of "synchronous climbing with different heights" is adopted. The top formwork construction is the construction of the vertical structure of the core tube first, and the horizontal structure or a separate organization lags behind the vertical structure by 4-7 floors. Construction is carried out separately. At this time, the construction of the steel structure of the outer frame and the composite floor still lags behind the vertical structure by 10-15 floors, forming a three-step construction organization. The overall organization of the horizontal structure is more difficult; or the horizontal structure and the horizontal structure of the outer frame are synchronized. Construction, lagging vertical structure 10-15 floors

The construction speed of the vertical structure of the core tube can reach the construction speed of one structural layer in 2.5 days at the fastest, but the follow-up horizontal structure is due to the consideration of the risk control of the vertical crossing operation objects, the height difference of the core tube slab surface, and the positioning of beams. Due to the changing characteristics, the construction speed of the floor structure is often difficult to match with the construction speed of the combined floor of the outer frame, forming mutual constraints. Because the horizontal structure cannot be completed in time, the key processes in the later stage of the super high-rise construction, such as the installation of electromechanical equipment and elevator installation, cannot be completed. Timely insertion, ultimately unable to maximize the effectiveness of the early stage of the vertical structure of the construction period advantage
