Referring to fig. 1 to 4, a first embodiment of the present invention provides a sectional assembly method of a high-rise building structure, wherein the high-rise building structure includes a first tower 1, a second tower 2, and a corridor 3, the first tower 1 includes a first building elevation 10, the first tower 1 and the second tower 2 are arranged at intervals, and the corridor 3 includes a first truss 30, a second truss 31, a third truss 32, and a fourth truss 34. The assembling method comprises the following steps:
101. The first truss 30 and the second truss 31 are formed by assembling the rod members, the rod members are lifted to a designated height, and part of the rod members are assembled to form the first truss 30, so that the first truss 30 is fixed on the first building elevation 10.
Wherein, the high-rise conjoined structure in this patent can be applied to high-rise building and super high-rise building. That is, the first tower and the second tower in this embodiment are both high-rise buildings or super high-rise buildings. Define a specified height as: from the height of the 34 th floor and above high-rise region of the first tower 1, if the designated height is H, H is not less than 27m, for example: 30m, 35m, 38m, 43m, etc.
Since the first truss 30 and the second truss 31 are installed close to the first turret 1, the bars may be spliced at a designated height by means of the first turret 1 to form the first truss 30 and the second truss 31. The rod pieces forming the first truss 30 and the second truss 31 are lifted to the designated height and then assembled, and the length of the rod pieces is relatively short because of the first truss 30 and the second truss 31 which are assembled relatively, so that the lifting is convenient, that is, each rod piece forming the first truss 30 and the second truss 31 can be lifted to the designated height without complex lifting equipment, and the lifting cost of the trusses can be saved.
In this embodiment, as shown in fig. 3, the first truss 30 is formed by cantilever-type assembly. The first truss 30 includes a first horizontal rod 301, a first vertical rod 302, an inclined rod 303, a second vertical rod 304, and a second horizontal rod 305, and the specific assembling steps of the first truss 30 are as follows:
a plurality of first horizontal rods 301 are horizontally assembled from top to bottom in sequence at a designated height, the first truss 30 is fixed on the first building facade 10, and a steel wire rope 300 is installed between two adjacent first horizontal rods 301, so that the stability of the first horizontal rods 301 is improved.
A plurality of first vertical rods 302 are vertically assembled at one end of the first horizontal rod 301 far away from the first building elevation 10, and two ends of each first vertical rod 302 are respectively connected with two adjacent first horizontal rods 301.
One end of the diagonal member 303 is fixed on the first building facade 10, and the other end of the diagonal member 303 is connected to the connection part of the uppermost first horizontal member 301 and the first vertical member 302 of the first truss 30, so that the diagonal member 303, the first horizontal member 301 and the first vertical member 302 form a triangle, and the stability of the first truss 30 can be further improved.
One end of the second vertical rod 304 is fixed at the connection of the uppermost first horizontal rod 301 and the first vertical rod 302 of the first truss 30.
One end of the second horizontal rod 305 is connected to the connection between the diagonal rod 303 and the first building facade 10, and the other end of the second horizontal rod 305 is fixedly connected to the second vertical rod 304.
102. The remaining bars are assembled at a designated height to form a second truss 31, and one end of the second truss 31 is fixed to the first building facade 10, and the other end of the second truss 31 is fixedly connected to the first truss 30, so that the projected patterns of the second truss 31, the first truss 30 and the first building facade 10 on the ground are triangular.
The rod pieces are assembled at the designated height of the first tower 1 to form the first truss 30 and the second truss 31, so that the projection patterns of the first truss 30, the second truss 31 and the first building elevation 10 on the ground are closed triangles, and then the trusses of the rest parts are spliced to form the corridor 3.
In this embodiment, the remaining members include a lower chord 310, a first diagonal web member 311, a second diagonal web member 312, an upper chord 313, a second vertical rod 314, and a plurality of reinforcement rods 315, and the first truss 30 includes a first vertical rod 30a, and the remaining members are assembled at a specified height to form the second truss 31, which specifically includes:
121. One end of the lower chord 310 is fixedly attached to the steel stud 101 of the first building facade 10 at a given height.
122. One end of the first diagonal member 311 is connected to the lower chord member 310, and the other end of the first diagonal member 311 is connected to the steel stud 101 such that the first diagonal member 311, the lower chord member 310, and the steel stud 101 form a triangle.
123. One end of the second diagonal member 312 is connected to the connection between the first diagonal member 311 and the lower chord member 310, and the other end of the second diagonal member 312 is connected to the first vertical member 30a, so that the second diagonal member 312, the lower chord member 310 and the first vertical member 30a form a triangle.
124. Two ends of the upper chord member 313 are fixedly connected to the connection between the first diagonal member 311 and the steel rib post 101 and the connection between the second diagonal member 312 and the first vertical rod 30a, respectively.
125. The second vertical rod 314 is vertically arranged between the upper chord 313 and the lower chord 310, one end of the second vertical rod 314 is connected to the upper chord 313, and the other end of the second vertical rod 314 is connected to the connection part of the first diagonal web member 311 and the lower chord 310.
126. A plurality of reinforcing rods 315 are horizontally assembled between the first diagonal web member 311, the second diagonal web member 312 and the first vertical rod 30 a.
When assembling the second truss 31, the lower chord member 310 and the first diagonal web member 311 are assembled first, so that the graph formed by the first diagonal web member 311, the lower chord member 310 and the steel rib column 101 is a closed triangle, and then the members of the rest parts are spliced to form the second truss 31.
It can be known that most of the existing splicing modes of the conjoined structure of the high-rise building generally lift the spliced truss to a designated position for installation, but by adopting the installation mode, the length of the spliced truss is relatively long and thin, the truss is suspended in the high air, and the structure becomes unstable, so that the safety, quality, construction period and construction cost of the construction engineering of the conjoined structure are directly influenced. In this patent, the relatively slender truss forming one side of the corridor 3 is first divided into the second truss 31 and the third truss 32, and then the second truss 31 and the third truss 32 are assembled separately, so that accidents caused by unstable truss structures due to the fact that the relatively slender truss of the corridor 3 is suspended in the high air can be avoided.
In this patent, since the first truss 30 mainly supports the second truss 31, the first truss 30 is preferably fixed vertically to the first building facade 10, and in the triangle formed by the first truss 30, the second truss 31 and the first building facade 10, the first truss 30 and the first building facade 10 are respectively two right-angle sides of the triangle, and the second truss 31 is the hypotenuse of the triangle. By adopting the installation mode, the stability of the second truss 31 on the first building elevation 10 can be further improved by utilizing the first truss 30, so that the condition that the second truss 31 installed at a specified height is unstable in structure due to suspension in the high air can be avoided, the safety and the quality of the construction engineering of the second truss 31 can be improved, and accidents can be avoided.
103. The third truss 32 is installed from the other end of the second truss 31 such that the third truss 32 extends to the second turret 2 and is fixed to the second turret 2 such that the third truss 32 and the second truss 31 together form one side truss of the corridor 3.
In this embodiment, to further improve the stability of the third truss 32, the gallery 3 further includes a fixed truss 33, the fixed truss 33 is vertically connected to the first building facade 10, and the fixed truss 33 is fixedly connected to the third truss 32 to support the third truss 32.
Since the third truss 32 is disposed across the first tower 1 and the second tower 2, and the relative distance between the first tower and the second tower is generally relatively long, the length of the third truss 32 needs to be relatively long, but since the third truss 32 needs to be lifted to a designated height for installation, the structure of the third truss 32 suspended at high altitude becomes unstable, which may affect the construction safety of the vestibule 3, the fixed truss 33 is preferably vertically fixed to the first building facade 10 to improve the stability of the third truss 32 on the first building facade 10.
It should be noted that, since the third truss 32 is to be installed in the high air finally, if the third truss 32 is to be formed by assembling the bars at a designated position like the first truss 30 and the second truss 31, it is necessary to construct a high-height (height greater than or equal to 27 m) carrying rack, but it is difficult to construct such a high rack in real construction, so that the third truss 32 and the fixed truss 33 are installed in such a manner that they are lifted to a designated height after being assembled together on the ground.
The third truss 32 and the fixed truss 33 are assembled on the ground and then lifted, so that the third truss 32 and the fixed truss 33 are convenient to lift, and the lifting efficiency of the third truss 32 and the fixed truss 33 is improved.
Further, it can be known that the third truss 32 and the second truss 31 together form one side truss of the gallery 3, that is, the one side truss of the gallery is constructed by sectioning the one side truss at the time of construction, and the second truss 31 is formed by splicing at a specified height, and the third truss 32 is formed by splicing at the ground, and then the third truss 32 is lifted to the specified height for installation. By adopting the construction mode, the occurrence of accidents caused by the unstable truss structure of the truss suspended in the high air can be avoided, and the safety of truss construction is improved; and because the trusses are not assembled into a whole on the ground and then lifted to the designated height for installation, the trusses forming the corridor 3 can be lifted to the designated height for assembly without complex lifting equipment, so that the truss is convenient and the lifting cost is low.
104. The fourth truss 34 is lifted to a designated height and the fourth truss 34 is fixedly connected to the first tower 1 and the second tower 2 such that the fourth truss 34 forms the other side truss of the gallery 3.
In this embodiment, similarly, since the fourth truss 34 is finally installed in the high altitude as the third truss 32, the fourth truss 34 is lifted to a predetermined height for installation after the ground assembly is completed.
105. A plurality of main beams 35 are assembled between the third truss 32 and the fourth truss 34.
In the present embodiment, in order to improve structural stability of the gallery 3, a plurality of main beams 35 are connected between the third truss 32 and the fourth truss 34.
106. A plurality of secondary beams 36 are assembled between adjacent two main beams 35.
In this embodiment, in order to further improve the structural stability of the gallery 3, a plurality of secondary beams 36 are provided between two adjacent primary beams 35.
The first embodiment of the invention provides a sectional assembly method of a high-rise conjoined structure, which can ensure the construction safety of a corridor by firstly assembling a stable structural system on a truss of a part of the corridor at a designated height and then assembling the rest trusses of the corridor. Specifically, the first truss and the second truss are formed by firstly assembling part rod pieces of the first truss and the second truss at the designated height of the first tower, and the first truss and the second truss are connected with each other, so that the projection patterns of the first truss, the second truss and the first building elevation on the ground are closed triangles, and then the trusses of other parts are lifted to the designated height for bottling to form the vestibule.
In addition, according to the sectional assembly method of the high-rise conjoined structure provided by the embodiment of the invention, each rod piece forming the first truss and the second truss is lifted to the designated high-rise installation position and then assembled, instead of being assembled integrally on the ground and then lifted to the designated high-rise installation position to be installed, by adopting the lifting mode, not only can each rod piece forming the truss be lifted to the designated position without complex lifting equipment, but also the length of each rod piece forming the truss is relatively short because each rod piece is lifted instead of the assembled truss, so that each rod piece of the conjoined structure is convenient to lift, and the construction cost is low.

However, most of the existing splicing modes of the connected structures of the high-rise buildings generally lift the spliced trusses to the designated positions for installation, but by adopting the installation mode, the length of the spliced trusses is relatively long, the trusses are hung in the high air, the structures of the trusses become unstable, and the safety, the quality, the construction period and the construction cost of the construction engineering of the connected structures are directly influenced. The truss gauge forming the high-rise conjoined structure is firstly divided into a plurality of partial trusses and then the trusses are assembled in a segmented mode. The method comprises the following steps: firstly, assembling bars at a designated height of a first tower 1 to form a first truss 30 and a second truss 31, so that projection patterns of the first truss 30, the second truss 31 and the first building elevation 10 on the ground are closed triangles, and then splicing the trusses of the rest parts to finally form the corridor 3. The formed closed triangle structure has good structural stability, so that the stability of the conjoined structure can be improved, and the safety and quality of the construction of the high-rise conjoined structure can be ensured.
Further, since the installation positions of the first truss 30 and the second truss 31 are close to the first turret 1, the bars can be spliced at a specified height by means of the first turret 1 to form the first truss 30 and the second truss 31. The rod pieces forming the first truss 30 and the second truss 31 are lifted to the designated height and then assembled, and the length of the rod pieces is relatively short because of the first truss 30 and the second truss 31 which are assembled relatively, so that the lifting is convenient, that is, each rod piece forming the first truss 30 and the second truss 31 can be lifted to the designated height without complex lifting equipment, and the lifting cost of the trusses can be saved.

By adopting the installation mode, the stability of the second truss 31 on the first building elevation 10 can be further improved by utilizing the first truss 30, so that the condition that the second truss 31 installed at a specified height is unstable in structure due to suspension in the high air can be avoided, the safety and the quality of the construction engineering of the second truss 31 can be improved, and accidents can be avoided.

Since the third truss 32 is disposed across the first tower 1 and the second tower 2, and the relative distance between the first tower and the second tower is generally relatively long, the length of the third truss 32 needs to be relatively long, but since the third truss 32 needs to be lifted to a designated height for installation, the structure of the third truss 32 suspended at high altitude becomes unstable, which may affect the construction safety of the vestibule 3, the fixed truss 33 is preferably vertically fixed to the first building facade 10 to improve the stability of the third truss 32 on the first building facade 10.

The following will briefly describe the assembly process of the gallery 3:
First, the rods assembled to form the first truss 30 and the second truss 31 are provided, the rods are lifted to a designated height, and part of the rods are assembled to form the first truss 30, so that the first truss 30 is fixed on the first building elevation 10. Then, the remaining bars are assembled at a designated height to form a second truss 31, and one end of the second truss 31 is fixed to the first building elevation 10, and the other end of the second truss 31 is fixedly connected to the first truss 30, so that the projected patterns of the second truss 31, the first truss 30 and the first building elevation 10 on the ground are triangular. Next, the third truss 32 and the fixed truss 33 are lifted to a designated height, the third truss 32 is installed from the other end of the second truss 31, and the third truss 32 is extended to the second turret 2 and fixed to the second turret 2 so that the third truss 32 and the second truss 31 together form one side truss of the gallery 3. Then, the fourth truss 34 is lifted to a designated height, the fourth truss 34 is lifted to the designated height, and the fourth truss 34 is fixedly connected to the first tower 1 and the second tower 2, so that the fourth truss 34 forms the other side truss of the corridor 3. Finally, lifting the main beams 35 and the secondary beams 36 to a designated height, and assembling a plurality of main beams 35 between the third truss 32 and the fourth truss 34; and a plurality of secondary beams 36 are assembled between two adjacent main beams 35, so that the assembly of the corridor 3 can be completed.
It should be noted that, since the third truss 32 is to be installed in the high air finally, if the third truss 32 is to be formed by assembling the bars at a designated position like the first truss 30 and the second truss 31, it is necessary to construct a high-height (height greater than or equal to 27 m) carrying rack, but it is difficult to construct such a high rack in real construction, so that the third truss 32 and the fixed truss 33 are installed in such a manner that they are lifted to a designated height after being assembled as a whole on the ground.
The third truss 32 and the fixed truss 33 are assembled on the ground and then lifted, so that the third truss 32 and the fixed truss 33 are convenient to lift, and the lifting efficiency of the third truss 32 and the fixed truss 33 is improved.
Further, it can be known that the third truss 32 and the second truss 31 together form one side truss of the gallery 3, that is, the one side truss of the gallery is constructed by sectioning the one side truss at the time of construction, and the second truss 31 is formed by splicing at a specified height, and the third truss 32 is formed by splicing at the ground, and then the third truss 32 is lifted to the specified height for installation. By adopting the construction mode, the occurrence of accidents caused by the unstable truss structure of the truss suspended in the high air can be avoided, and the safety of truss construction is improved; and because the trusses are not assembled into a whole on the ground and then lifted to the designated height for installation, the trusses forming the corridor 3 can be lifted to the designated height for assembly without complex lifting equipment, so that the truss is convenient and the lifting cost is low.
Similarly, since the fourth truss 34 is finally installed in the high altitude as the third truss 32, the fourth truss 34 is lifted to a predetermined height for installation after the ground assembly is completed.
