Description

Technical Field

[0001] This application relates to the field of steel structure construction, and in particular to a method for the integrated improvement of super high-rise connected steel structures, auxiliary structures, and decoration. Background Technology

[0002] With rapid socio-economic development, long-span steel corridors are widely used in various high-rise buildings, complexes, airports, and other large public / commercial buildings. These corridors connect large single buildings, improving the efficiency of personnel movement. Due to their excellent lighting and expansive views, steel corridors are often used as sightseeing walkways or leisure cafes, significantly enhancing the functional use of buildings.

[0003] Commonly used construction methods for long-span steel connecting corridors include: integral hoisting, high-altitude assembly, segmented installation, high-altitude sliding, and integral lifting. Among these, the integral lifting method is relatively new. This method involves assembling the structure on a corresponding ground-based formwork, minimizing high-altitude work, and the lifting is not limited by the weight or span of the structure. Furthermore, assembling structural components on the ground ensures high-quality welding.

[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 installation of sub-projects such as the bottom ceiling, bottom electromechanical pipelines, and curtain wall of the steel corridor, which are already at high altitude, still needs to be carried out at high altitude. High-altitude operations are risky, dangerous, and difficult to guarantee construction quality. At the same time, high-altitude operations will also lead to a significant 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 conjunction with auxiliary structures, decoration and other disciplines is an urgent problem to be solved in the hydraulic lifting technology of super high-rise connected steel structures. Summary of the Invention

[0006] To reduce the dangers during the installation of connecting corridors, this application provides a method for the integrated lifting of super high-rise connected steel structures, auxiliary structures, and decoration.

[0007] The technical solution provided in this application for an integrated lifting method for super high-rise connected steel structures, auxiliary structures, and decoration is as follows:

[0008] A method for integrating super high-rise connected steel structures with auxiliary structures and decoration into a single upgrade includes the following steps:

[0009] Step 1: Establish an accurate three-dimensional finite element model;

[0010] Step 2: Conduct detailed finite element numerical simulations for each working condition of the truss unit;

[0011] Step 3: Obtain the precise deformation values ​​of the bottom truss;

[0012] Step 4: During the installation process, deformation values ​​and 3D laser scanning technology, combined with adjustable clips, are used to conduct real-time deformation control of the main steel truss, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels.

[0013] Step 5: Installation of the jig and main truss;

[0014] Step Six: Installation of steel truss floor decking and installation of internal electromechanical pipelines in the suspended ceiling;

[0015] Step 7: Pre-lifting: After the truss is lifted off the support, it is suspended at a distance of 100mm from the support for 4-12 hours. During this period, the lifting bracket support and the integrated truss lifting structure itself are inspected and tested. If the structure is severely deformed, the integrated part should be immediately lowered to the support and the situation should be analyzed and dealt with before lifting again.

[0016] Step 8: After pre-lifting and testing the corbel support and the connecting truss, and ensuring that the structural strength, stiffness and stability meet the requirements, the main truss is lifted to a height of 3 meters to provide sufficient space for the construction of the suspended ceiling at the bottom of the steel structure corridor.

[0017] Step 9: Set up temporary support: The truss is raised to a position 3 meters away from the lowest point of the basement roof and suspended for one month. During the suspension period, horizontal hand-operated hoists are set up and fixed to the steel-concrete columns of the main structure on the 1st to 3rd floors. GPS positioning is used to lay out the lines on the top of the basement columns. Steel structure columns that can be adjusted in real time by hydraulic jacks and corresponding sweeping rods are installed at the corresponding positions on the top of the basement columns.

[0018] Step 10: Install the bottom ceiling;

[0019] Step 11: Formal Lifting: The main truss, electromechanical pipelines, steel truss floor decking, and bottom ceiling decoration are lifted as a whole to the target position.

[0020] Step 12: Post-construction connection of structural members, weld inspection, splicing of floor deck slab finishing sections, reinforcement binding and pouring of concrete floor slab for connecting corridor;

[0021] Step Thirteen: Installation of lifting components at the top of the truss;

[0022] Step Fourteen: Side facade curtain wall installation;

[0023] Step 15: Construction of the light well and roof garden.

[0024] By adopting the above technical solutions, the integrated lifting of the super high-rise connected steel structure and its ancillary structures and decoration can be achieved, significantly reducing the amount of high-altitude work and improving construction safety and project quality. A precise three-dimensional finite element model was established and detailed finite element numerical simulations were conducted to ensure the safety and reliability of the truss units under various working conditions, improving design accuracy. Deformation numerical analysis and three-dimensional laser scanning technology, combined with adjustable clips, were used to control the deformation of the main steel truss, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels in real time, effectively preventing structural deformation problems during construction and ensuring construction quality and safety. The use of a jig and main truss installation steps allowed the main truss to be assembled on the ground, reducing the difficulty of high-altitude work. Structural safety was ensured by suspending the structure at a specific height during the pre-lifting stage and inspecting the structure. Temporary support steps further ensured the stability and safety of the truss during the lifting process. After being officially lifted to the target position, steps such as post-lifting member connection and weld flaw detection ensured the integrity and safety of the connecting corridor structure. Finally, the complete installation of the connecting corridor's ancillary structures was achieved through the installation of the top lifting components of the truss and the side facade curtain wall, improving construction efficiency. The aforementioned technical methods enable the bottom ceiling and electromechanical pipelines to be installed on the ground before being lifted as a whole, achieving overall coordinated lifting and efficient construction of the steel connecting corridor and its ancillary electromechanical pipelines and decorative structures, thereby improving construction efficiency and reducing construction risks.

[0025] Preferably, the installation of the steel truss floor deck in step six includes fixing the steel truss floor deck to a first-floor truss and welding it securely.

[0026] By adopting the above technical solution, the steel truss floor deck is fixed to the first-floor truss and welded firmly, ensuring a stable connection between the floor deck and the truss, and improving the safety and reliability of the overall structure.

[0027] Preferably, the installation of electromechanical pipelines inside the ceiling in step six includes ventilation ducts and air conditioning pipelines inside the ceiling;

[0028] In step eight, temporary support components are installed at the bottom of the pre-lifted and hovered position.

[0029] The temporary support structure will be equipped with a digital jacking device that adjusts the elevation in real time;

[0030] The temporary support components are used to temporarily fix the main truss to facilitate the installation of the bottom honeycomb aluminum panel and other decoration and finishing works.

[0031] By adopting the above technical solution, the installation of electromechanical pipelines inside the ceiling includes ventilation ducts and air conditioning pipelines inside the ceiling. Temporary support components are installed at the bottom after pre-lifting and suspension. Since the owner's choice to add fresh air or central air conditioning drawings cannot be determined at the moment, the system's flexibility and adaptability are improved, which facilitates flexible adjustments according to the owner's needs and reduces the risk of high-altitude operations. At the same time, the digital jacking device with real-time adjustable elevation can be used through the temporary support components, which also facilitates the installation of bottom honeycomb aluminum panels and other decoration and renovation works.

[0032] Preferably, the pre-lifting process in step seven also includes checking the structural deformation of the truss during the hovering period.

[0033] By adopting the above technical solution, during the pre-lifting process, after the truss is lifted and detached from the support, it is suspended at a distance of 100mm from the support for 4 to 12 hours. During this period, the structural deformation of the truss is checked to ensure structural safety, reduce the risk of subsequent lifting, and make the lifting process more reliable.

[0034] Preferably, the temporary support setup in step nine includes securing the main structure to the 1st to 3rd floor reinforced concrete columns using a hand-operated hoist during the hovering period.

[0035] By adopting the above technical solution, the truss was raised to a position 3 meters above the lowest point of the basement roof and suspended for a month. During the suspension period, the main structure was fixed to the reinforced concrete columns of the 1st to 3rd floors using hand-operated hoists. This ensured the safety of construction during the suspension phase, facilitated the installation of the bottom ceiling and electromechanical pipelines, and reduced the risks and difficulties of high-altitude operations.

[0036] Preferably, the formal lifting speed in step eleven is 6m / h, and the lifting is completed within two days. Before the formal lifting, the working space of the bottom ceiling construction unit must be 2-3 meters.

[0037] By adopting the above technical solution, a working space of 2-3 meters must be ensured for the bottom ceiling construction unit before the formal lifting, which ensures sufficient working space for the bottom ceiling construction, improves the safety and quality of construction; at the same time, by controlling the speed and time of the formal lifting, the stability and safety of the lifting process are ensured, reducing the risks and construction difficulties of high-altitude operations.

[0038] Preferably, the post-construction member connection in step twelve includes initial connection with bolts, followed by welding and weld inspection, and temporary member removal to complete the transition from the construction state to the structural state.

[0039] By adopting the above technical solution, the post-construction member connection includes initial connection with bolts, followed by welding and fixing, and weld flaw detection. Temporary members are then removed to complete the transformation from the construction state to the structural state, ensuring the overall stability and safety of the structure.

[0040] Preferably, step 12 includes repairing the end of the first-floor truss deck and installing the second, third, and fourth-floor truss decks.

[0041] By adopting the above technical solution, the finishing part of the first-floor truss deck was repaired, and the second, third, and fourth-floor truss decks were installed, ensuring the integrity of the deck and the stability of the structure, and reducing the risks and construction difficulties of subsequent high-altitude operations.

[0042] Preferably, in step thirteen, the lifting component at the top of the truss is installed on the top of the connected truss to meet the installation conditions of the side facade curtain wall.

[0043] By adopting the above technical solution, the lifting components at the top of the truss are installed on the top of the connected truss to meet the installation conditions of the side facade curtain wall, which improves the convenience and safety of the side facade curtain wall installation and ensures construction quality and efficiency.

[0044] Preferably, the construction of the light well and roof garden in step fifteen is carried out after the connecting corridor is lifted and positioned.

[0045] By adopting the above technical solutions, the construction of the skylight and roof garden was ensured to be carried out after the connecting corridor was lifted and placed, avoiding structural safety risks and construction quality hazards that might have been caused by early construction. This achieved the integrated lifting of the super high-rise connected steel structure and its ancillary structures and decoration, significantly reducing the amount of high-altitude work and improving construction efficiency and safety.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] 1. Ensure the safety and stability of the super high-rise connected steel structure during the lifting process, and realize the overall coordinated lifting and efficient construction of the steel connecting corridor and its ancillary electromechanical pipelines and decoration structures, thereby improving construction efficiency and reducing construction risks;

Detailed Implementation

[0057] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0058] This application discloses a method for integrating the construction of a super high-rise connected steel structure with its auxiliary structures and decorative finishing. (Refer to...) Figure 1 A method for integrating super high-rise connected steel structures with auxiliary structures and decoration includes the following steps:

[0059] Step 1: Establish an accurate three-dimensional finite element model;

[0060] Step 2: Conduct detailed finite element numerical simulations for each working condition of the truss unit;

[0061] Establish accurate three-dimensional finite element models and conduct detailed finite element numerical simulations to ensure the safety and reliability of truss units under various working conditions and improve design accuracy.

[0062] Step 3: Obtain the precise deformation values ​​of the bottom truss;

[0063] Step 4: During the installation process, deformation values ​​and 3D laser scanning technology, combined with adjustable clips, are used to conduct real-time deformation control of the main steel truss, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels.

[0064] By combining deformation numerical and three-dimensional laser scanning technologies with adjustable buckles, real-time deformation control is achieved for the main steel truss, bottom hangers, electromechanical pipelines, and honeycomb aluminum panels, effectively preventing structural deformation problems during construction and ensuring construction quality and safety.

[0065] Step 5: Installation of the jig and main truss;

[0066] Reference Figure 2Specifically, the jig is also called the assembly platform. The installation of the assembly platform is as follows: During the ground assembly stage, a steel structure assembly platform is erected on the roof of the basement. Each support column of the assembly platform uses H-beams. To meet the load-bearing requirements, the dimensions are set as H: 600, B1: 400, tw: 20, tf1: 36, which are the height / width / web / flange thickness, respectively. The positioning lines are set on the top of the corresponding structural column in the basement.

[0067] 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.

[0068] Reference Figure 4 During the assembly of the first-floor truss, the truss structure can be composed of main beams made of high-strength H-beams and secondary beams made of box-type structural steel. Simultaneously, finite element analysis is performed on the steel structure model using Midas to evaluate the deformation value of the first-floor main truss after the overall assembly of the first-floor steel corridor. The connection between the main beams and secondary beams is achieved through welding or high-strength bolts, ensuring the overall stability and structural strength of the truss. When removing the support points, the entire truss can be lifted using a hydraulic system, and then the support points can be removed.

[0069] Step Six: Installation of steel truss floor decking and installation of internal electromechanical pipelines in the suspended ceiling;

[0070] Reference Figure 5 Specifically, the electromechanical pipelines at the bottom of the truss and the ceiling are installed simultaneously with the installation of the steel truss floor decks for each truss layer. The steel truss floor deck consists of multiple steel trusses and a concrete slab laid on them. The steel trusses have straight reinforcing bars and diagonal reinforcing bars. The straight reinforcing bars can be made of 15mm diameter threaded steel bars, and the diagonal reinforcing bars can be made of 12mm diameter threaded steel bars.

[0071] The bottom of the floor decking can be welded and fixed using a steel truss structure to ensure its stability and connection strength. For the bottom ceiling installation, the specific sequence is: truss bottom electromechanical pipelines, hangers - main keel - secondary keel - honeycomb aluminum panels. This preparation prevents installation deviations due to gravity-induced deflection. The installation of electromechanical pipelines inside the ceiling includes the installation of ventilation ducts and air conditioning pipelines. Ventilation ducts can be installed using prefabricated rectangular air ducts made of galvanized steel sheets and connected via flanges. For the air conditioning pipelines inside the ceiling, if the homeowner chooses a fresh air system, the fresh air ducts will be pre-installed; if central air conditioning is chosen, the air conditioning ducts will be pre-installed. The ductwork installation must consider the use of insulation and soundproofing materials to ensure quiet and comfortable operation.

[0072] Step 7: Pre-lifting: After the truss is lifted off the support, it is suspended at a distance of 100mm from the support for 4-12 hours. During this period, the lifting bracket support and the integrated truss lifting structure itself are inspected and tested. If the structure is severely deformed, the integrated part should be immediately lowered to the support and the situation should be analyzed and dealt with before lifting again.

[0073] Specifically, after the truss is lifted off the support, it should be suspended at a distance of about 100mm from the support for 4-12 hours. During this period, a laser rangefinder should be used to measure the deformation of each part of the truss. If severe deformation of the truss is found, the lifting should be stopped immediately, and the truss should be lowered back onto the support for analysis and treatment to ensure the safety of subsequent lifting.

[0074] Step 8: After pre-lifting and testing the corbel support and the truss, and confirming that the structural strength, stiffness and stability meet the requirements, the main truss is lifted to a height of 3 meters.

[0075] Specifically, after the structural strength, stiffness and stability are satisfied, the main truss will be raised to 3 meters to provide space for the construction of the suspended ceiling at the bottom of the steel structure corridor.

[0076] Step 9: Set up temporary support: The truss is raised to a position 3 meters away from the lowest point of the basement roof and suspended for one month. During the suspension period, horizontal hand-operated hoists are set up and fixed to the steel-concrete columns of the main structure on the 1st to 3rd floors. GPS positioning is used to lay out the lines on the top of the basement columns. Steel structure columns that can be adjusted in real time by hydraulic jacks and corresponding sweeping rods are installed at the corresponding positions on the top of the basement columns.

[0077] Specifically, the truss will be raised to a position 3 meters above the lowest point of the basement ceiling and suspended for one month. During this period, the main structure will be secured to the reinforced concrete columns on floors 1-3 using hand-operated hoists. The hand-operated hoists can utilize a specially designed cantilever beam structure, with the top of the cantilever beam fixed to the reinforced concrete column and the bottom connected to the truss via bolts. Additionally, uprights and corresponding ground-level bracing will be installed at the top of the basement columns to ensure construction safety during the suspension phase. The uprights can be made of steel pipes and welded to the top of the basement columns, while the ground-level bracing will be made of channel steel and welded to the uprights. (See reference...) Figure 3 The columns are made of square or H-shaped steel with reinforcing ribs at both ends. Ear plates are welded to the top of the columns, and lifting holes are opened in the ear plates for lifting the truss. Jacks are installed at the bottom of the columns, and the elevation of the top steel truss can be adjusted in real time through the jacks. At the same time, this structure can further reduce the uneven lifting of the lifting points during the integrated lifting of the large-span steel truss before hydraulic lifting.

[0078] Step 10: Installation of the bottom ceiling (honeycomb aluminum panel);

[0079] Specifically, the bottom ceiling (honeycomb aluminum panels) is installed on the main truss of the temporary support.

[0080] Step 11: Formal Lifting: The main truss, electromechanical pipelines, steel truss floor decking, and bottom ceiling decoration are lifted as a whole to the target position.

[0081] Specifically, during the actual lifting process, the main truss, electromechanical pipelines, steel truss floor slabs, and bottom ceiling decoration will be lifted as a whole at a speed of 6m / h, and the lifting will be 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 their construction.

[0082] Step 12: Post-construction connection of structural members, weld inspection, splicing of floor deck slab finishing sections, reinforcement binding and pouring of concrete floor slab for connecting corridor;

[0083] Specifically, initial bolt connections are used to ensure rapid fixation. During the welding process, weld quality is ensured to improve the overall durability and reliability of the connecting corridor. Weld inspection is conducted using ultrasonic testing technology to ensure the structure is defect-free, thus enhancing safety. After weld inspection, temporary members are removed to complete the transition from the construction phase to the structural phase. The splicing of the floor decking joints is carried out after the main truss structure is completed. This includes supplementing the joints of the first-floor truss floor decking and installing the second, third, and fourth-floor truss floor deckings. After the floor deckings are installed, rebar tying and concrete pouring are carried out. High-strength steel mesh is used during rebar tying, and concrete pouring further enhances the overall strength.

[0084] Step Thirteen: Installation of lifting components at the top of the truss;

[0085] Specifically, to meet the installation requirements of the side facade curtain wall, lifting equipment is installed on the top of the connected truss.

[0086] Step Fourteen: Side facade curtain wall installation;

[0087] Specifically, during the installation of the side facade curtain wall, the aforementioned lifting components are used to install the side facade curtain wall, ensuring installation accuracy and speed.

[0088] Step 15: Construction of the light well and roof garden.

[0089] Specifically, the construction of the light well and roof garden will be carried out after the connecting corridor is lifted and in place.

[0090] This ensured that the construction of the skylight and rooftop garden was carried out after the connecting corridor was lifted and in place, avoiding structural safety risks and potential construction quality hazards that might have been caused by premature construction. It also achieved the integrated lifting of the super high-rise connected steel structure and its ancillary structures and decoration, significantly reducing the amount of high-altitude work and improving construction efficiency and safety.

[0091] The implementation principle of this application's embodiment of an integrated lifting method for a super high-rise connected steel structure, its auxiliary structures, and decoration is as follows: The integrated lifting of the super high-rise connected steel structure, its auxiliary structures, and decoration significantly reduces the amount of high-altitude work and improves construction safety and project quality. The use of a jig and main truss installation steps allows the main truss to be assembled on the ground, reducing the difficulty of high-altitude operations. By suspending the structure at a specific height during the pre-lifting stage and inspecting the structure, structural safety is ensured. The provision of temporary supports further guarantees the stability and safety of the truss during the lifting process. After the structure is officially lifted to the target position, steps such as adding supplementary members and weld inspection ensure the integrity and safety of the connecting corridor structure. Finally, the complete installation of the connecting corridor's auxiliary structures is achieved through the installation of the lifting components at the top of the truss and the side facade curtain wall, improving construction efficiency. These technical means allow the bottom ceiling and electromechanical pipelines to be installed on the ground before the overall lifting, effectively avoiding the risks associated with high-altitude operations.

[0092] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
