Description

Technical Field

[0001] The present application relates to the field of steel structure construction, and more particularly to a method for integrating the lifting of a super-high-rise connected steel structure with auxiliary structures and decoration. Background Art

[0002] With the rapid development of social economy, large-span steel corridors are widely used in various large public / commercial buildings such as super-high-rise buildings, complexes, airports, etc. Large-span steel corridors realize the connection between large single buildings and improve the efficiency of personnel activities. Steel corridors are often used as sightseeing corridors or leisure cafes due to their good lighting effects and wide views, and the use of building functions has been greatly improved.

[0003] At present, the commonly used construction methods for large-span steel corridors are: overall hoisting method, high-altitude bulk method, block installation method, high-altitude sliding method and overall lifting method. Among them, the relatively new construction method is the overall lifting method, which completes the structural assembly on the corresponding ground frame, with less high-altitude work, and the lifting is not restricted by the weight and span of the structure. At the same time, the structural components are assembled on the ground, and the welding quality is guaranteed.

[0004] However, currently the overall lifting of steel structure corridors is mostly done by hydraulic lifting of the steel structure frame. For super-high-rise steel corridors, only the steel structure frame is hydraulically lifted. After the steel frame is lifted into place, the sub-projects such as the bottom ceiling, bottom electromechanical pipelines, and curtain walls of the steel corridor that are already at high altitudes still need to be installed at high altitudes. High-altitude operations are risky and dangerous, and the construction quality is difficult to guarantee. At the same time, high-altitude operations will also lead to a substantial increase in construction costs.

[0005] Therefore, for super-high-rise connected steel structures, the integrated lifting of the main steel structure of the steel corridor in coordination with the auxiliary structure, decoration and other multi-disciplinary techniques is an urgent problem to be solved in the hydraulic lifting technology of super-high-rise connected steel structures. Summary of the invention

[0006] In order to reduce the danger during the installation of the corridor, the present application provides an integrated lifting method for a super-high-rise connected steel structure in coordination with ancillary structures and decorations.

During this period, the lifting bracket support and the joint truss lifting structure itself are inspected and tested. If the structure is severely deformed, the joint part should be immediately dropped to the bracket and the situation should be analyzed and dealt with before re-lifting; Step 8: After pre-lifting, after testing the strength, stiffness and stability of the corbel support, connected trusses and other structures, the main trusses are lifted to 3 meters to meet the requirements of the ceiling construction work space at the bottom of the steel structure corridor; Step 9: Set up temporary support: The truss is lifted to a height of 3 meters from the lowest point of the basement roof and suspended for one month. During the suspension period, a horizontal hand chain hoist is set to fix it to the steel concrete columns of the 1st to 3rd floors of the main structure. GPS positioning is used to lay out the lines at the top of the basement columns. Steel structure columns and corresponding sweeping rods that can be adjusted in real time by hydraulic jacks are installed at the corresponding positions on the top of the basement columns. Step 10: Installation of bottom ceiling (honeycomb aluminum panel); Step 11: Formal lifting: The main truss, electromechanical pipelines, steel truss floor decking and bottom ceiling decoration are formally lifted to the target position as a whole; Step 12: connect the supplementary rods, inspect the welds, splice the floor decking joints, tie the steel bars and pour the corridor concrete slab; Step 13: Installation of lifting components on top of truss; Step 14: Installation of side facade curtain wall; Step 15: Construction of light well and top garden.

At the same time, the digital jacking device with real-time adjustment of the elevation can be used through temporary supporting components, and the installation of the bottom honeycomb aluminum panel and other decorative projects is convenient.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses a method for integrating the lifting of a super high-rise connected steel structure with auxiliary structures and decoration. Figure 1 A method for integrating super high-rise connected steel structures with auxiliary structures and decoration and renovation includes the following steps: Step 1: Establish an accurate three-dimensional finite element model; Step 2: Carry out detailed finite element numerical simulation for each working condition of the truss unit; Establish accurate three-dimensional finite element models and carry out detailed finite element numerical simulations to ensure the safety and reliability of truss units under various working conditions and improve design accuracy.

[0036] Step 3: Obtain the accurate deformation value of the bottom truss; Step 4: During the installation process, deformation values ​​and 3D laser scanning technology are used in combination with adjustable buckles to carry out real-time deformation control of the main trusses of the steel structure, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels; By utilizing deformation numerical values ​​and 3D laser scanning technology combined with adjustable buckles, real-time deformation control is performed on the main trusses of the steel structure, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels, effectively preventing structural deformation problems during construction and ensuring construction quality and safety.

[0037] Step 5: Install the tire frame and main truss; Reference Figure 2Specifically, the tire frame is also called the assembly platform. The assembly platform is installed as follows: During the ground assembly stage, a steel structure assembly platform is set up on the top plate of the basement. Each support column of the assembly platform adopts H-shaped steel. To meet the bearing capacity requirements, the size is set to H: 600, B1: 400, tw: 20, tf1: 36, which are height / width / web / flange thickness respectively. It is set on the top of the corresponding structural column in the basement through positioning and laying out. Reference Figure 1 , Figure 4 and Figure 6 , the first floor (80.850m) truss was assembled, the support points on the beams were removed, the second floor (85.050m) truss was assembled, the third floor (89.250m) truss was assembled, and the fourth floor (93.480m) truss was assembled; Reference Figure 4 When assembling the first-floor truss, the truss structure can be composed of a main beam made of high-strength H-shaped steel and a secondary beam made of box-type structural steel. At the same time, the steel structure model is calculated by finite element calculation using midas, and the deformation value of the first-floor main truss after the first-floor steel corridor is assembled is evaluated through refined calculation. The connection between the main beam and the secondary beam is welding or high-strength bolt connection to ensure the overall stability and structural strength of the truss. When the support point is removed, the truss can be lifted as a whole by the hydraulic system, and then the support point can be removed.

[0038] Step 6: Installation of steel truss floor decking and mechanical and electrical pipelines inside the ceiling; Reference Figure 5 Specifically, the steel truss floor deck of each layer of truss is installed while the electromechanical pipelines and ceiling are installed at the bottom of the truss. The steel truss floor deck includes multiple steel trusses and concrete slabs laid thereon. The steel trusses have straight reinforcement bars and oblique reinforcement bars. The straight reinforcement bars can be threaded steel bars with a diameter of 15 mm, and the oblique reinforcement bars can be threaded steel bars with a diameter of 12 mm.

[0039] The bottom of the floor deck can be fixed by welding the steel structure truss to ensure its stability and connection strength. For the bottom ceiling, the specific order is: the electromechanical pipeline at the bottom of the truss, the hanger-main keel-secondary keel-honeycomb aluminum plate, and preparations are made for installation to prevent installation deviations caused by gravity deflection; the installation of electromechanical pipelines inside the ceiling includes the installation of ventilation ducts and air-conditioning pipelines. The ventilation duct can be installed through a prefabricated rectangular duct, which is made of galvanized steel plates and connected by flanges. For the air-conditioning pipeline part inside the ceiling, if the owner chooses a fresh air system, the fresh air duct will be installed in advance; if a central air conditioner is selected, the air-conditioning duct will be installed in advance. The pipeline laying needs to consider the use of thermal insulation and sound insulation materials to ensure the quietness and comfort of the pipeline during operation.

[0040] Step 7: Pre-lifting: After the truss is lifted and separated from the bracket, it is suspended at a distance of 100mm from the bracket for 4-12 hours. During this period, the lifting bracket support and the joint truss lifting structure itself are inspected and tested. If the structure is severely deformed, the joint part should be immediately dropped to the bracket and the situation should be analyzed and dealt with before re-lifting; Specifically, after the truss is lifted and detached from the bracket, it is suspended at a distance of about 100 mm from the bracket for 4-12 hours. During this period, a laser rangefinder is used to measure the deformation of each part of the truss. Once the truss is found to be seriously deformed, the lifting should be stopped immediately and the truss should be dropped back onto the bracket for analysis and processing to ensure the safety of subsequent lifting.

[0041] Step 8: After pre-lifting, the main truss is lifted to 3 meters after the structural strength, stiffness and stability of the corbel support and the connected truss meet the requirements; Specifically, after the structural strength, stiffness and stability are met, the main truss will be lifted to 3 meters to provide space for the ceiling construction at the bottom of the steel structure corridor.

[0042] Step 9: Set up temporary support: The truss is lifted to a height of 3 meters from the lowest point of the basement roof and suspended for one month. During the suspension period, a horizontal hand chain hoist is set to fix it to the steel concrete columns of the 1st to 3rd floors of the main structure. GPS positioning is used to lay out the lines at the top of the basement columns. Steel structure columns and corresponding sweeping rods that can be adjusted in real time by hydraulic jacks are installed at the corresponding positions on the top of the basement columns. Specifically, the truss is lifted to a height of 3 meters from the lowest point of the basement ceiling and suspended for one month, during which the main structure is fixed to the reinforced concrete columns of the 1st to 3rd floors by a hand winch. The hand winch can adopt a special cantilever beam structure, the top of the cantilever beam is fixed to the reinforced concrete column, and the bottom is connected to the truss by bolts. In addition, columns and corresponding sweeping rods are set on the top of the basement columns to ensure construction safety during the suspension stage. The columns can be made of steel pipes and fixed to the top of the basement columns by welding, and the sweeping rods are made of channel steel and fixed to the columns by welding. Figure 3 The columns are made of square or H-shaped steel with reinforcing ribs at both ends. Ear plates are welded on the top of the columns with lifting holes for lifting the trusses. Jacks are set at the bottom of the columns. The elevation of the top steel trusses can be adjusted in real time by the jacks. At the same time, this structure can further reduce the uneven lifting of each lifting point during the integrated lifting of the large-span steel trusses before hydraulic lifting.

[0043] Step 10: Installation of bottom ceiling (honeycomb aluminum panel); Specifically, the bottom ceiling (honeycomb aluminum panel) is installed on the main truss of the temporary support.

[0044] Step 11: Formal lifting: The main truss, electromechanical pipelines, steel truss floor decking and bottom ceiling decoration are formally lifted to the target position as a whole; Specifically, during the formal lifting process, the main trusses, electromechanical pipelines, steel truss floor decking and bottom ceiling decoration are lifted as a whole at a speed of 6m / h, and the lifting is completed within two days. Before lifting, it is necessary to ensure that the bottom ceiling construction unit has 2-3 meters of working space to facilitate the ceiling unit to carry out construction.

[0045] Step 12: connect the supplementary rods, inspect the welds, splice the floor decking joints, tie the steel bars and pour the corridor concrete slab; Specifically, bolts are used for preliminary connection to ensure quick fixation, and the quality of welds is ensured during the welding and fixation process, thereby improving the overall durability and reliability of the corridor. Weld flaw detection is carried out using ultrasonic testing technology to ensure that the structure is free of defects, thereby ensuring improved safety. After the weld flaw detection is completed, the temporary rods are removed to complete the transition from the construction state to the structural state. The splicing of the floor decking closing parts is carried out after the construction of the main truss structure is completed, specifically including the supplementary installation of the closing parts of the first-floor truss floor decking, and the installation of the second, third, and fourth-floor truss floor decking. After the floor decking is installed, steel bar binding and concrete pouring are carried out. During the steel bar binding process, high-strength steel mesh is used, and concrete is poured to enhance the overall strength.

[0046] Step 13: Installation of lifting components on top of truss; Specifically, in order to meet the installation conditions of the side facade curtain wall, a lifting device is installed on the top of the connected truss.

[0047] Step 14: Side facade curtain wall installation; Specifically, during the installation of the side facade curtain wall, the lifting component is used to install the side facade curtain wall to ensure installation accuracy and speed.

[0048] Step 15: Construction of light well and top garden.

[0049] Specifically, the construction of the light well and the top garden will be implemented after the corridor is lifted into place.

[0050] It ensures that the construction of the light well and the top garden is carried out after the corridor is lifted into place, avoiding the structural safety risks and construction quality hidden dangers that may be caused by premature construction. It realizes the integrated lifting of the super-high-rise connected steel structure and its ancillary structures and decoration, significantly reduces the amount of high-altitude operations, and improves construction efficiency and safety.

[0051] The implementation principle of the integrated lifting method of a super-high-rise connected steel structure in coordination with ancillary structures and decorations in the embodiment of the present application is as follows: the super-high-rise connected steel structure and its ancillary structures and decorations can be lifted in an integrated manner, which significantly reduces the amount of high-altitude operations and improves construction safety and project quality. The tire frame and main truss installation steps are adopted, so that the main truss can be assembled on the ground, reducing the difficulty of high-altitude operations; the structural safety is ensured by hovering at a specific height and inspecting the structure during the pre-lifting stage; the temporary support step is set to further ensure the stability and safety of the truss during the lifting process; after being officially lifted to the target position, the integrity and safety of the corridor structure are ensured through the subsequent rod connection, weld flaw detection and other steps; finally, through the installation of the truss top lifting components and the side facade curtain wall installation, the complete installation of the corridor ancillary structure is achieved, improving construction efficiency. The above-mentioned technical means enable the bottom ceiling and electromechanical pipelines to be lifted as a whole after the installation is completed on the ground, effectively avoiding the risks brought by high-altitude operations.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
