Description

Technical Field

[0002] This application relates to the field of steel structure construction technology, and in particular to a method for rapid installation of multiple ground-supporting columns. Background Technology

[0003] Stiffened columns combine the advantages of steel and concrete structures, achieving a balance between high load-bearing capacity and small cross-sections. They are widely used in large spatial structures such as high-speed railway stations and airport terminals. Traditional stiffened column construction typically employs a "layered staggered" method: installing one steel column section → pouring concrete for that section → waiting for the concrete to reach the required standard → installing the next steel column section → pouring concrete, and so on. This method has the following drawbacks in complex environments with multiple terraces: 1. Severe overlap in work processes and low mechanical efficiency: The frequent alternation between the two major processes of steel structure hoisting and concrete pouring leads to the repeated entry, exit, and switching of large equipment such as tower cranes and pump trucks. The scheduling within the confined space of multiple sites is extremely difficult, which greatly slows down the construction period.

[0004] 2. Temporary measures occupy critical space: After each steel column is installed, a large number of guy ropes are required for temporary fixation until the concrete of that section is poured and hardened. These guy ropes crisscross, seriously encroaching on the working space for subsequent scaffolding erection, formwork support and concrete pouring, creating safety hazards and reducing work efficiency.

[0005] 3. The precision control chain is lengthy and the risk of cumulative error is high: the shrinkage and deformation after each concrete pour may affect the already corrected steel column, and the installation benchmark of the next steel column will change accordingly, resulting in the accumulation of errors layer by layer, making it difficult to control the overall verticality.

[0006] Therefore, there is an urgent need for a new method that can overcome the above-mentioned defects, adapt to multiple terrace environments, and achieve rapid and high-quality construction of stiffened columns. Summary of the Invention

[0007] Therefore, it is necessary to provide a rapid installation method for multiple ground-supported columns to overcome the shortcomings of traditional column construction methods in complex environments with multiple ground platforms, such as large interference from overlapping procedures, temporary fixing measures occupying effective working space, difficulty in deploying large machinery, and difficulty in systematically controlling construction accuracy.

[0008] A method for rapid installation of multiple ground-supporting columns includes the following steps: S1. Modular overall installation of steel structure: Based on the division of construction areas according to the site platform, an independent hoisting route is planned. Large mobile hoisting equipment is used to complete the hoisting, measurement, correction and node connection of all steel column segments of stiffened columns and permanent and temporary combined column support system in each area in sequence, forming a complete self-supporting steel structure frame system. S2. Concrete integration and subsequent pouring: After the steel structure frame system has passed final acceptance, formwork support and concrete pouring are carried out on the outer perimeter of the steel profiles of all stiffened columns. Before pouring, the temporary support structure in the permanent and temporary column support system is gradually removed.

[0009] As a preferred embodiment of the rapid installation method for multiple ground-supporting columns in this invention, in step S1, the steel column segment of the supporting column includes a foundation column, a second-section column, and a third-section column arranged sequentially, which are connected to the foundation. The second-section column is a cross-shaped column, and the third-section column is a circular tube column.

[0010] As a preferred embodiment of the rapid installation method for multiple ground-supported columns in this invention, in step S1, the permanent and temporary combined column support system includes column supports and steel plate walls. The column supports are installed between two adjacent column sections, and the steel plate walls are installed between some of the two adjacent column sections.

[0011] As a preferred embodiment of the rapid installation method for multiple ground-supported columns in this invention, in step S1, the permanent and temporary combined column support system includes a permanent support structure and a temporary support structure. The permanent support structure includes steel plate walls and secondary beams. The steel plate walls are arranged between adjacent two-section columns spaced apart along a first direction, and the secondary beams are arranged between adjacent two-section columns spaced apart along a second direction. The temporary support system includes column supports and guy ropes. The column supports are arranged between the remaining adjacent two-section columns spaced apart along the first direction and are removed after the overall steel structure frame is stably formed and before the concrete pouring process begins. The guy ropes are used to fix the individual steel columns during the fine-tuning stage before the installation of the permanent support structure, and are removed after the column forms a stable connection with the adjacent structure.

[0012] As a preferred embodiment of the rapid installation method for multiple ground stiffeners in this invention, the inter-column support is welded to the stiffener, and after being cut off, the stiffener in the connection area is ground, repaired, and rust-proofed.

[0013] As a preferred embodiment of the rapid installation method for multiple ground-supporting columns in this invention, step S1 specifically includes the following steps: S1.1 Hoist the foundation column, connect the bottom of the foundation column to the foundation platform, and then measure and correct it; S1.2 Hoist the two-section column. After the two-section column is connected to the connecting structure, measure and correct it, and install the permanent and temporary combined support system. S1.3. Depending on the type of foundation column, decide whether to tie and pour part of the concrete structure. The pouring height should be above the connection between the foundation column and the second-section column. Pour when the foundation column is an H-shaped column, and do not pour when the foundation column is a cross-shaped column. S1.4. After hoisting the three columns and connecting them with the two columns, measure and correct them. The stiffened columns and the permanent and temporary combined column support system form a complete self-supporting steel structure frame system.

[0014] As a preferred embodiment of the rapid installation method for multiple ground-supporting columns in this invention, step S1, specifically includes: establishing a high-precision construction measurement control network that is consistent with the coordinates of the design model; using a total station to collect the three-dimensional coordinates of preset measuring points on the steel components being installed in real time and dynamically comparing them with the theoretical coordinates of the model; and using tools such as jacks and steel wedges to precisely adjust the verticality, axis, and elevation of the components.

[0015] As a preferred embodiment of the rapid installation method for multiple ground-supporting columns in this invention, in step S1, the verticality of the steel columns is corrected by simultaneously monitoring with two theodolites at 90 degrees to each other, and the deviation is corrected by applying jacks to the side of the column or by driving in steel wedges.

[0016] As a preferred embodiment of the rapid installation method for multiple ground-supported columns in this invention, in step S2, before concrete pouring, shear connectors are welded onto the surface of the steel profile of the support column; during pouring, a symmetrical and continuous layered approach is adopted, and the deformation of the steel structure frame under concrete load is monitored in real time.

[0017] As a preferred method for the rapid installation of multiple ground-supporting columns in this invention, before step S2 begins, the final spatial configuration of the steel structure frame system is fully measured and verified, and the data is recorded as a benchmark for deformation monitoring during concrete pouring.

[0018] As a preferred embodiment of the rapid installation method for multiple ground-supported columns in this invention, after step S2 is completed, standard curing of the concrete is carried out, and after the concrete reaches the predetermined strength, the final state of the support column system is retested to complete the construction loop.

[0019] The beneficial effects of this invention are: This invention enables continuous steel structure installation and centralized concrete pouring, avoiding frequent process switching. Large hoisting equipment can continuously complete the installation of all steel components in one area before transferring them, and pumping equipment can centrally pour large areas of concrete, significantly improving equipment utilization and shortening the construction period by 15%-30%.

[0020] This invention provides stability by utilizing permanent supports and adding removable temporary fixing mechanisms, essentially eliminating the need for long-term guy ropes. This provides an unobstructed three-dimensional space for subsequent operations such as scaffolding erection, formwork installation, rebar tying, and concrete vibration, reducing safety risks and improving the convenience of operations for various trades.

[0021] The steel structure frame in this invention is installed, aligned, and poured in one go, eliminating the intermittent disturbances caused by layered concrete pouring and improving the quality of the single pour. Combined with BIM-based digital measurement technology, it enables overall optimization and precise one-time control of the entire frame's spatial configuration, resulting in higher installation accuracy and more stable quality.

[0030] According to one aspect of this application, embodiments of this application provide a method for rapid installation of multiple ground reinforcement columns. Please refer to [link to relevant documentation]. Figure 1 The rapid installation method for multiple stiffened columns mainly includes two steps: modular overall installation of steel structure and integrated post-concrete pouring. Modular overall installation of steel structure involves dividing the construction area according to the site platform, planning independent hoisting routes, and using large mobile hoisting equipment to sequentially complete the hoisting, measurement, correction, and node connection of all stiffened column steel column segments and permanent-temporary combined column support system in each area, forming a complete self-supporting steel structure frame system. Integrated post-concrete pouring involves uniformly providing formwork support and pouring concrete on the outer perimeter of all stiffened columns after the final acceptance of the steel structure frame system.

[0031] In one embodiment, before carrying out the modular overall installation of the steel structure, construction preparation is required, which includes: Technical Preparation: First, based on the design drawings, detailed design of the steel structure construction drawings is carried out, and a building information model containing the dimensions, coordinates, and nodes of all components is established. This model will serve as the sole data source for subsequent surveying and setting out, virtual pre-assembly, and construction management. A comprehensive construction organization design is prepared, including specific plans for hoisting, surveying, welding, and concrete pouring, and detailed technical and safety briefings are conducted for all management and operational personnel.

[0032] Measurement preparation: Based on the site conditions, a two-level construction survey control network is established. The first-level network consists of the site benchmarks provided by the owner. The second-level network consists of six stable control points densely arranged around the building. High-precision total stations are used to conduct the survey and adjustment according to the national first-level traverse survey standard to ensure that its coordinate system is consistent with the coordinate system of the building information model.

[0033] Equipment and material preparation: crawler cranes will be used as the main hoisting equipment. Sufficient high-strength bolts, welding materials, jacks, theodolites, total stations, guy ropes, temporary auxiliary beams, formwork systems, etc. will be prepared.

[0034] In one embodiment, the modular overall installation phase of the steel structure is used to complete the installation and stabilization of all steel structures within a construction area in one go, specifically including: Construction area division and hoisting route planning: Based on the platform elevation and structural joints, the site is divided into multiple independent construction areas. A dedicated travel route is planned for the crawler crane. The route is located at the center of the structural axis, with an axis spacing of 11 meters, ensuring that all components on both sides of the route are covered within a hoisting radius of 22 meters.

[0035] Segmental hoisting and connection of steel column segments for stiffened columns: The steel column segments of stiffened columns include a foundation column, a second column, and a third column, which are set in sequence.

[0036] Foundation column installation: such as Figure 2 As shown, the foundation columns include cross-shaped columns and H-shaped columns. When cross-shaped columns are used as foundation columns, anchor bolts are pre-embedded in the foundation during the foundation construction stage, such as... Figure 8 As shown, the cross-shaped column is connected to the foundation after the reinforcement of the foundation is poured. During the foundation construction stage, anchor bolts need to be pre-embedded to connect the cross-shaped column. The connection structure at the bottom of the cross-shaped column is connected to the top of the foundation through pre-embedded anchor bolts and L-shaped reinforcing members. When using H-shaped columns as foundation columns, as shown... Figure 9 As shown, the H-shaped column needs to be pre-embedded inside the foundation cap. During the foundation cap reinforcement binding stage, the H-shaped column is inserted into the foundation cap reinforcement and connected to the foundation cap reinforcement through a support frame. After the connection is completed, the foundation cap concrete is poured, and the H-shaped column is pre-embedded inside the foundation cap. When hoisting the foundation column, the crawler crane is positioned on the planned route, and after the foundation column is hoisted above the foundation cap and initially connected, a theodolite is used to initially correct its verticality in two directions.

[0037] Two-section column installation: (e.g., ...) Figure 3 As shown, the two-section column is a cross-shaped steel column. Before hoisting, a special lifting tool is hung on the pre-set lifting lugs on the upper part. It is hoisted to about 200mm above the installed foundation column and then paused. After stabilization, it is slowly lowered to align the lug holes at the joint between the upper and lower columns. Temporary installation bolts are then inserted. Figure 4 As shown, at this stage, guy ropes are immediately installed at the four corners of the column top for temporary fixation.

[0038] Partial concrete pouring: When the foundation column is an H-shaped column, the lower part of the foundation column needs to be poured and fixed. A formwork is erected at the bottom of the foundation column, and partial concrete is poured at the connection between the lower part of the foundation column and the foundation platform. The pouring height reaches the top of the transition node between the H-shaped column and the cross column to enhance the connection strength of the bottom structure.

[0039] Three-section column installation: as follows Figure 6 As shown, the third column is a circular tube column, and it is connected to the second column using the same hoisting process as the second column.

[0040] Installation of permanent and temporary combined column bracing system: Permanent support structure installation: such as Figure 4As shown, during the two-column installation stage, secondary beams as required by the design are installed in a timely manner between adjacent two-column sections spaced apart along the second direction, and steel plate walls are installed between adjacent two-column sections spaced apart along the first direction where greater lateral stiffness is required.

[0041] Temporary support structure installation: like Figure 5 As shown, in areas with large spans or irregular structural plans, permanent support structures alone cannot provide sufficient rigidity during the construction phase. Therefore, temporary inter-column bracing needs to be added at the design locations of the two-section columns or at critical stress points. Temporary inter-column bracing typically uses angle steel or H-beams, such as... Figure 7 As shown, its two ends are temporarily connected to the stiffened columns via corbels or pre-set ear plates. During the fine-tuning stage of the individual steel columns before the installation of the permanent support structure, the individual steel columns are fixed with guy ropes. Once the column has formed a stable connection with the adjacent structure, it is removed to make way for subsequent work. The function of the temporary support structure is to provide additional lateral restraint and stiffness before the overall steel frame structure achieves final stability. The stiffened columns and the combined permanent and temporary column support system form a complete self-supporting steel frame system.

[0042] The entire process of high-precision measurement and calibration: Measurement and calibration: Calibration work is carried out throughout the hoisting process. Two theodolites are used, with stations set up simultaneously in two directions at 90 degrees to each other on the steel column to be calibrated, to observe the center line on the column.

[0043] Verticality correction: Based on the deviation data observed by the theodolite, the operator applies a horizontal force to the column using a hydraulic jack on the opposite side of the deviation direction, or drives steel wedges into the gap between the column bases, and gradually adjusts the verticality deviation to the allowable range of the specification.

[0044] Digital coordinate verification: Simultaneously, surveyors use a total station to collect the three-dimensional coordinates of preset measuring points on the top of the steel column or corbel in real time, and immediately compare them dynamically with the theoretical coordinates of the point in the building information model. The coordinate deviation is fed back to the calibration personnel, realizing closed-loop precise control of measurement-feedback-adjustment, ensuring that the axis deviation is ≤5mm and the elevation deviation is within ±3mm.

[0045] Final fixing of nodes: After all corrections are met, high-strength bolts are tightened or welded to the nodes of column-column, column-support, and column-beam. The welding process is qualified. For thick plate welding, preheating before welding, control of interpass temperature, and post-weld insulation measures are implemented.

[0046] In one embodiment, after the steel structure frame has passed final acceptance, the integrated concrete pouring is carried out, which includes the following steps: Preparations before pouring: Removal of temporary support structures: All inter-column supports installed during the modular steel structure assembly are gradually removed. The beams are carefully cut off using flame cutting, preserving the areas connected to the columns. After removal, the stiffened columns in the connection area are ground to remove weld spatter and heat-affected zones, making them smooth and flat. Then, epoxy zinc-rich primer is immediately applied for rust prevention.

[0047] Welded shear connectors: Shear connectors such as cylindrical head studs are welded onto the steel surface of the stiffened column according to design requirements.

[0048] Formwork support: Due to the absence of guy ropes, the prefabricated formwork and supporting scaffolding system around the stiff columns can be erected efficiently and tightly.

[0049] Integral casting construction: Measurement and verification benchmark: Before the concrete pouring begins, a total station is used to perform a full measurement and verification of the final spatial configuration of the entire steel frame system, and the data is recorded in detail. This data will serve as the benchmark value for monitoring structural deformation during the pouring process.

[0050] Pouring process: Multiple concrete pump trucks are used to pour concrete continuously and uniformly for all stiffened columns within a construction area. The principle of symmetrical zoning and continuous layering is strictly followed. For example, the pouring proceeds symmetrically from the middle to both ends, with the thickness of each layer controlled within 500mm. The height difference between the concrete surfaces of adjacent columns is ensured to be no more than 500mm, and immersion vibrators are used to fully compact the concrete.

[0051] Real-time deformation monitoring: During the pouring process, surveyors use a total station to monitor the coordinate changes at the top of key steel columns in real time, comparing them with recorded benchmark values ​​to dynamically understand the deformation of the steel structure frame under concrete loads and lateral pressures. If abnormal deformation is detected, an immediate warning is issued and the pouring sequence or speed is adjusted.

[0052] In one embodiment, after the integral concrete pouring is completed, post-curing and final acceptance are required, which includes the following steps: Concrete curing: After pouring, immediately cover the concrete surface with geotextile and spray water to keep it moist for curing time of no less than 14 days.

[0053] Final state re-measurement: After the concrete strength reaches 100% of the design strength, the formwork is removed. The final axial position, verticality, and elevation of all stiffened columns are re-measured using a total station and level, and a measurement report is generated. The results are then compared with the design values ​​and specification requirements to complete the closed-loop control of construction quality.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
