The following detailed description is made with reference to the accompanying drawings.
Referring to fig. 1 to 4, in an embodiment of the present invention, a multi-corridor construction method for a super high-rise building is provided, in which each corridor is configured to be connected between a first tower 31 and a second tower 32, each corridor includes a high-area corridor and a low-area corridor, the high-area corridor is disposed above the low-area corridor, and the high-area corridor includes a first high-area corridor portion 11, a second high-area corridor portion 12, and a first high-area steel beam 13 and a second high-area steel beam 14 connected between the first high-area corridor portion 11 and the second high-area corridor portion 12. The low area corridor includes a first low area corridor part 21, a second low area corridor part 22, and a first low area steel beam 23 and a second low area steel beam 24 connected between the first low area corridor part 21 and the second low area corridor part 22.
In the present embodiment, the high-area corridor is a corridor provided at 34 th to 37 th floors in a super high-rise building having more than forty floors, and the low-area corridor is a corridor provided at 6 th to 9 th floors in a super high-rise building having more than forty floors.
The multi-corridor construction method comprises the following steps:
s1: the first high area corridor part 11 is spliced and the first high area corridor part 11 is fixed to the first tower 31 and the second tower 32.
In this step, the high district vestibule of the highest department of constructing earlier in the vestibule work progress can effectively reduce the component that lies in high district vestibule lower part in the work progress and promote the influence of process to high district vestibule, is favorable to improving the efficiency of construction.
Further, referring to fig. 1, fig. 2 and fig. 4, in the step S1, the first high-zone corridor part 11 includes a first high-zone truss 111, a second high-zone truss 112, a third high-zone truss 113 and a fourth high-zone truss 114, and then the step S1 specifically includes the following steps:
s11: the first high-area truss 111 and the third high-area truss 113 are scattered and spliced at the first designated height, the first high-area truss 111 and the first tower 31 are fixedly connected, and the third high-area truss 113 is fixedly connected to the first tower 31 and the first high-area truss 111, so that the projected patterns of the third high-area truss 113, the first high-area truss 111 and the first tower 31 on the ground are triangular (as shown in fig. 4).
In this step, the first designated height refers to the height of the corridor located higher, i.e. the corridor in the high area, when the corridors with different heights are arranged in the super high-rise building. For example, a certain super high-rise building has forty floors, wherein high area corridors are arranged on the thirty-fourth to thirty-seventh floors, and the first designated height is the height of the thirty-fourth to thirty-seventh floors. Preferably, the first designated height may be 140m to 160m, such as 140m, 143m, 150m, 160m, and the like.
Specifically, when the first high-region truss 111 and the third high-region truss 113 are assembled in a scattered manner, the third high-region truss 113 may be assembled in a scattered manner first, and the third high-region truss 113 may be constructed in a cantilever method in a scattered manner at high altitude, and then the first high-region truss 111 is assembled in a scattered manner. In this way, when the first high-region truss 111 is fixed to the first tower 31, the third high-region truss 113 may be used to support and fix the first high-region truss 111, so that the first high-region truss 111 may be firmly and stably fixed in the high altitude and to the first tower 31. In addition, a stable triangular structure is formed between the first high-area truss 111 and the third high-area truss 113 and the first tower 31, which is beneficial to improving the structural stability of the third high-area truss 113 and the first high-area truss 111 after installation, thereby improving the construction safety of splicing and fixing the first high-area truss 111 and the third high-area truss 113 in high altitude and being beneficial to improving the quality of corridor construction.
S12: the second high zone truss 112 and the fourth high zone truss 114 are assembled on the ground.
In this step, the second high-area truss 112 and the fourth high-area truss 114 are assembled on the ground, because the second high-area truss 112 and the fourth high-area truss 114 are complex in structure, long in length and large in size, the second high-area truss 112 and the fourth high-area truss 114 are assembled on the ground more conveniently and quickly than in the air, so that the second high-area truss 112 and the fourth high-area truss 114 can be assembled quickly, and the construction of the first high-area corridor 11 can be completed by lifting to a first specified height, so that the construction efficiency of the first high-area corridor 11 is improved, and the safety and reliability of the construction are also ensured.
It can be seen that the second high zone truss 112 is longer than the third high zone truss 113 and the fourth high zone truss 114 is longer than the first high zone truss 111 in the length direction (as shown in fig. 5).
S13: and lifting the assembled second high area truss 112 and the fourth high area truss 114 to a first designated height.
In this step, the second high-zone truss 112 and the fourth high-zone truss 114 are lifted together, thereby improving the construction efficiency.
S14: a fourth high area truss 114 is connected to the junction of the third high area truss 113 and the first high area truss 111, and such that the fourth high area truss 114 extends to the second tower 32 and is secured to the second tower 32 (as shown in fig. 5).
S15: the second high-area truss 112 is fixedly connected to the fourth high-area truss 114 and the second high-area truss 112 is vertically fixed to the first tower 31 to support and fix the fourth high-area truss 114 (as shown in fig. 5).
In this manner, the provision of the second high-area truss 112 facilitates providing a supporting foundation for the already installed first high-area vestibule portion 11, further improving the structural stability of the first high-area vestibule portion 11.
Meanwhile, the fourth high-region truss 114 can be supported and fixed by the second high-region truss 112, so that the installation stability and the construction safety of the fourth high-region truss 114 can be effectively improved.
In addition, since the fourth high-area truss 114 is fixedly connected to the first high-area truss 111, extends from the position connected to the first high-area truss 111 to the second tower 32, and is fixed to the second tower 32, the fourth high-area truss 114 and the first high-area truss 111 together form a side truss of the corridor.
Therefore, the invention adopts the technical scheme that one side truss forming the corridor of the high area is segmented and assembled, the third high area truss 113 with shorter length is firstly fixed on the first tower 31 after being assembled on the first designated height in a scattered mode, the first high area truss 111 is also assembled on the first designated height in a scattered mode and then is supported and fixed on the first tower 31 by the third high area truss, then the fourth high area truss 114 with longer length is assembled on the ground and then is lifted to the first designated height to be fixedly connected with the third high area truss 113, the fourth high area truss 114 is positioned and fixed by the third high area truss 113, and then the fourth high area truss 114 can be firmly and firmly fixed on the second tower 32 by the supporting function of the second high area truss 112. By adopting the mode, the traditional mode that one side truss of the corridor of the high area is integrally assembled on the ground and then integrally lifted is replaced, the construction is more convenient (the high altitude and the ground can be assembled simultaneously), and the third high area truss 113 is assembled in the high altitude and can be assembled by adopting a cantilever method without using too many lifting devices, and the truss is lifted in sections, so that the lifting difficulty can be reduced, and the safety and the reliability of the construction are improved.
S2: the second high area corridor part 12 is spliced and the second high area corridor part 12 is fixed to the first tower 31 and the second tower 32.
In this step, referring to fig. 5, a second high area corridor portion 12 forms the other side of the high area corridor. Because the length of the second high area corridor part 12 is short compared to the length of the first high area corridor part 11, the second high area corridor part 12 does not need to be segmented. It will be appreciated that in other embodiments, the second high area corridor part 12 may be assembled in a segmented manner if the length of the second high area corridor part 12 is long, i.e. the distance between the first tower 31 and the second tower 32 is too large.
Further, as shown in fig. 5, in the step S2, the second high area corridor part 12 includes the fifth high area truss 121, and the step S2 specifically includes the following steps:
s21: the fifth high zone truss 121 is assembled on the ground.
S22: and lifting the assembled fifth high-area truss 121 to a first designated height, and enabling one end of the fifth high-area truss 121 to be fixedly connected to the first tower 31 and the other end of the fifth high-area truss 121 to be fixedly connected to the second tower 32.

In this step, the second designated height is the height of the corridor located at the lower position, i.e. the corridor in the high area, when the corridors with different heights are arranged in the super high-rise building. For example, a super high-rise building has forty floors, wherein low-area corridors are arranged from the sixth floor to the ninth floor, and the second designated height is the height from the sixth floor to the ninth floor.
Specifically, the second designated height is smaller than the first designated height, and the second designated height may be approximately 20m to 40m, such as 20m, 22m, 23m, 30m, 35m, 40m, and so on.
