Problems solved by technology

Since the construction speed of the vertical structure of the core tube using the top formwork system can reach 3 days and one floor, the construction speed of the horizontal structure of the core tube is far behind the vertical structure; therefore, the construction progress of the vertical structure of the core tube appears to be ahead Due to the construction progress of the horizontal structure, and with the elongation of the construction time, the construction progress of the horizontal structure is far behind the construction progress of the vertical structure, thus forming a large height difference
When the height difference between the two reaches a certain level, it brings a major safety hazard, which is specifically manifested in the impact of vertical structure construction on horizontal structure construction by falling objects, which not only affects the construction progress but also affects the construction personnel. Construction safety poses a hazard

Embodiment 1

[0037] refer to figure 1 with figure 2 , figure 1 It shows the construction status of the core tube layer jumping construction method of the present invention Figure 1 , figure 2 It shows the construction status of the core tube layer jumping construction method of the present invention Figure II . The core tube in the core tube floor jumping construction method of this embodiment includes a horizontal structure and a vertical structure 20, and the first horizontal structure 11, the second horizontal structure 12, and the intermediate horizontal structure 10 in this embodiment all belong to the horizontal structure, because The chronological order of the construction of the three is different, and the names are distinguished in order to describe this embodiment more conveniently and clearly.

[0038] When the construction story height of the vertical structure 20 in the core tube is higher than that of the horizontal structure, multiple groups of lattice support colum...

Embodiment 2

[0045] refer to Figure 1 to Figure 3 , image 3 It shows the construction status of the core tube layer jumping construction method of the present invention Figure three . In this embodiment, the first horizontal structure 11 , the second horizontal structure 12 , the third horizontal structure 13 and the middle horizontal structure 10 are all horizontal structures.

[0046] As can be seen from the above figure, elevator shafts 60 are reserved on both sides of the horizontal structure in this embodiment, and the lattice support columns 30 between the first horizontal structure 11 and the second horizontal structure 12, and the second horizontal structure 12 The lattice type support columns 30 between the third horizontal structure 13 are all installed above the elevator shaft 60; specifically, a plurality of support beams 70 are first set above the elevator shaft 60, and one end of the support beams 70 is anchored at the first level structure 11 or the second horizontal s...

Abstract

The invention discloses a core tube skip-floor construction method which comprises the following steps: arranging a lattice support column between a built first horizontal structure and a to-be-built second horizontal structure; and erecting a construction platform of the second horizontal structure at the top of the lattice support column, wherein the first horizontal structure and the second horizontal structure are spaced by a to-be-constructed middle horizontal structure; constructing the second horizontal structure on the construction platform of the second horizontal structure; and sequentially erecting a construction platform of the middle horizontal structure between the first horizontal structure and the second horizontal structure and constructing the middle horizontal structure on the body of the lattice support column below the built second horizontal structure. Therefore, the security threat of falling objects caused by the influence of the construction of the vertical structure on the construction of the middle horizontal structure between the first horizontal structure and the second horizontal structure is avoided by use of the protection effect of the built second horizontal structure.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a core tube floor-jumping construction method. Background technique [0002] With the gradual improvement of construction technology, there are more and more construction demands for super high-rise large buildings; the core tube of super high-rise large buildings is often constructed with the top formwork system. The traditional construction method is to first construct the vertical structure of the core tube through the top formwork system, and then use the conventional method to construct the horizontal structure of the core tube. Since the construction speed of the vertical structure of the core tube using the top form system can reach one floor in three days, the construction speed of the horizontal structure of the core tube is far behind the vertical structure; therefore, the construction progress of the vertical structure of the core tube appears to be ahead Due to t...
