[0041] In order to solve the problem of high difficulty and long installation period of climbing form installation and deployment in a narrow construction site, the present application provides a climbing form assembly and core tube synchronous construction method. The following takes the core tube construction of an ultra-high building as a specific embodiment to further illustrate the climbing form assembly and core tube synchronous construction method in combination with the drawings.

[0042] Referring to Figure 1 A climbing form assembly and core tube synchronous construction method is shown, comprising the steps of:

[0043] Step S1, bind the first section of core tube reinforcement at the core tube construction position, and install the first climbing cone pre-embedded part on the outside, and then pour the first section of core tube. Specifically: before performing this step S1, first perform climbing form design according to the main structure drawing, determine the climbing form machine position arrangement and the composition of each part of the climbing form frame body, then simulate the installation sequence of the building site and the climbing form frame body using BIM and animation demonstration, determine the construction steps of the core tube, and then design the installation sequence of the climbing form frame body according to the construction steps; when performing this step S1, cooperate Figure 2 First, set up the inner operating frame 11 inside the core tube and the outer operating frame 12 outside the core tube at the core tube construction position, bind the first section of core tube reinforcement and install the first climbing cone pre-embedded part 21 using the inner operating frame 11 and the outer operating frame 12, then set up the first section of core tube formwork and pour the first section of core tube 31.

[0044] Step S2, bind the second section of core tube reinforcement, and install the second climbing cone pre-embedded part on the inside and outside, and then hang the outer wall climbing form lower frame body on the first climbing cone pre-embedded part 21. Specifically, cooperate Figure 3 First, raise the inner operating frame 11 and the outer operating frame 12, bind the second section of core tube reinforcement and install the second climbing cone pre-embedded part 22 on both sides using the raised inner operating frame 11 and the outer operating frame 12, then remove the outer operating frame 12 and the first section of core tube formwork before hanging the outer wall climbing form lower frame body 41, then install the wall attachment support on the first climbing cone pre-embedded part 21, install the climbing form hanging seat on the inside of the outer wall climbing form lower frame body 41, then hoist the pre-assembled outer wall climbing form lower frame body 41 so that its climbing form hanging seat is hung on the wall attachment support, thereby realizing the hanging of the outer wall climbing form lower frame body 41. Further cooperate Figure 7As shown, the lower frame 41 of the climbing formwork includes a lower column 411, a main platform 412 for formwork operation fixed to the inner side of the lower column 411, a climbing component installed at the bottom of the platform 412, and a climbing formwork template retraction device 413 installed at the top of the platform 412. The height of the lower column 411 is not less than the height of a section of the core tube. The climbing component includes a hydraulic cylinder 414, a climbing guide rail, and a hydraulic platform. Through the cooperation of the hydraulic cylinder 414 with the climbing guide rail, the wall support, and the climbing formwork hanger, the lower frame 41 of the climbing formwork can achieve the climbing action along the outer wall of the core tube. The climbing formwork template retraction device 413 can drive the core tube template to move back and forth, so as to provide a climbing channel for the climbing of the frame.

[0045] Step S3: Erect a temporary operating frame 13 on the main operating platform 412 of the template, use the inner operating frame 11 and the temporary operating frame 13 to support the second core tube template, move the outer wall climbing formwork template rearward moving device 413 forward so that it abuts against the outside of the second core tube template, and then close the formwork and pour the second core tube 32.

[0046] Step S4, Cooperation Figure 4 and Figure 5 As shown, the temporary operating frame 13 and the second section of the core tube formwork are dismantled. Then, the pre-assembled upper frame 42 of the external wall climbing formwork is fixed to the lower frame 41 of the external wall climbing formwork to form the overall frame 40 of the external wall climbing formwork. Next, the third section of the core tube reinforcement is tied, and the third set of climbing cone embedded parts 23 are installed on both the inner and outer sides. Further coordination... Figure 8 As shown, the external wall climbing formwork upper frame 42 includes an upper column 421 and at least two steel reinforcement binding platforms fixed to the inner side of the upper column 421 (such as...). Figure 8 The system includes an upper rebar tying platform 422 at the top and a lower rebar tying platform 423 in the middle. An upper column 421 is fixed to the main formwork operation platform 412 and directly faces the lower column 411. The sum of the heights of the upper column 412 and the lower column 411 is not less than the sum of the heights of the two core tube sections. The height of the lower rebar tying platform 423 facilitates the tying of the third core tube rebar by construction workers. The upper rebar tying platform 422 can be used to tie the fourth core tube rebar or temporarily store rebar and other building materials. After fixing the upper formwork frame 42 to the lower formwork frame 41 to form the overall formwork frame 40, a protective net 424 is installed on the outside of the overall formwork frame 40.

[0047] Step S5: Using the climbing assembly, the main frame 40 of the external wall climbing formwork is raised until the lower frame 41 of the external wall climbing formwork is hung on the second climbing cone embedded part 22 on the outer side. During the climbing process, the external wall climbing formwork template retraction device 413 is first moved away from the core tube to form a climbing channel. Further, in conjunction with... Figure 9As shown, the external wall climbing form is provided with a climbing form lifting platform 50, which is installed at the bottom of the external wall climbing form total frame body 41. Then, the climbing form lifting platform 50 is used to remove the wall-attached support on the first climbing cone embedded part 21.

[0048] In step S6, the construction personnel on the template operation main platform 412 of the climbing form set the third section of the core tube template, move the external wall climbing form template rear moving device 413 to abut against the outside of the third section of the core tube template, and then close the template to pour the third section of the core tube 33.

[0049] In step S7, the internal tube climbing form total frame body 60 is hung on the second climbing cone embedded part 22 on the inner side. Specifically, the internal operation frame 11 and the third section of the core tube template are removed before being hung. The internal tube climbing form total frame body 60 is the same as the external wall climbing form total frame body 40, and also includes a lower frame body and an upper frame body. The lower frame body also has a climbing assembly for climbing. For the case of using wall-attached supports and climbing form hanging seats to realize the hanging of the frame body, the bottom of the lower frame body is also provided with a climbing form lifting platform for removing the wall-attached supports on the lower part after climbing. The internal tube climbing form total frame body 60 can be installed by segmental hoisting or by pre-assembling and then hoisting as a whole. After installation, it is symmetrical to the external wall climbing form total frame body 40.

[0050] The internal tube climbing form total frame body 60 and the external wall climbing form total frame body 40 form a complete climbing form. When other sections of the core tube are constructed, the climbing form is used to realize the construction by climbing. Specifically, after the internal tube climbing form total frame body 60 is hung on the second climbing cone embedded part 22 on the inner side, the external wall climbing form total frame body 40 is hung on the second climbing cone embedded part 22 on the outer side, and then the internal tube climbing form total frame body 60 and the external wall climbing form total frame body 40 are simultaneously climbed until they are hung on the third climbing cone embedded part 23 on the inner and outer sides, respectively. Figure 6 As shown:

[0051] In step S8, the construction personnel can bind the fourth section (i.e., the next section) of the core tube reinforcement by means of the upper and lower steel reinforcement binding platforms (422, 423) of the external wall climbing form total frame body 40 and the corresponding steel reinforcement binding platforms of the internal tube climbing form total frame body 60, and install the fourth climbing cone embedded part 24 on the inner and outer sides.

[0052] In step S9, the internal tube climbing form total frame body 60 and the external wall climbing form total frame body 40 are simultaneously climbed until they are hung on the third climbing cone embedded part 23 on the inner and outer sides, respectively.

[0053] In step S10, the fourth section of the core tube template is set, and the fourth section of the core tube 34 is poured after the template is closed. After pouring, the fourth section of the core tube template is removed.

[0054] In step S11, steps S8 to S10 are repeated until the core tube is completely poured.

[0055] The application avoids the problems of insufficient site, tower crane not meeting hoisting demand, high difficulty of installation and deployment of climbing formwork in narrow construction site, long installation period and the like caused by concentrated pouring and concentrated assembly, and facilitates temporary storage of reinforcing steel and the like building materials by setting reinforcing steel binding platform on the climbing formwork structure. In addition, simulation of site, climbing formwork installation sequence and the like by using BIM and animation demonstration can optimize construction steps, make climbing formwork assembly and core tube each process reasonably interpenetrate construction, improve construction efficiency and shorten construction period.

[0056] The application is described in detail above in combination with the embodiments of the drawings, and those skilled in the art can make various changes to the application according to the above description. Therefore, certain details in the embodiments should not constitute a limitation on the application, and the scope of protection of the application will be defined by the appended claims.
