Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of formwork reinforcement, in particular to a quick-release square column reinforcement construction method. BACKGROUND

[0002] Formwork reinforcement is an indispensable part of foundation construction and one of the essential links in concrete forming construction. The traditional reinforcement process (square wood + round pipe) has a complicated operation process, from square wood cutting, round pipe splicing, to multi-layer binding and fixing, which requires professional carpenters to operate meticulously based on their rich experience, resulting in low construction efficiency and high labor cost. Moreover, the probability of reusing square wood after use is very low, which easily leads to material waste and the improvement of square wood on the bending resistance of concrete columns is very limited, which easily causes the formwork to expand during pouring construction, resulting in poor entity forming quality. SUMMARY

[0003] Therefore, the purpose of the present application is to provide a quick-release square column reinforcement construction method to solve the technical problems mentioned in the prior art.

[0004] The quick-release square column reinforcement construction method comprises the following steps:

[0005] According to the construction drawing, a prefabricated structural member and a reinforcement operation instruction book are configured, and an operator installs the prefabricated structural member to the surface of the square column to be reinforced for reinforcement operation according to the reinforcement operation instruction book; wherein the reinforcement operation instruction book is configured as:

[0006] S1, installing a pre-embedded support member on the surface of the square column to be reinforced;

[0007] S2, building a support formwork on the outer circumferential side of the pre-embedded support member;

[0008] S3, using a plurality of sets of reinforcing members to fix the support formwork located on the opposite sides of the square column to be reinforced to the outer circumferential side of the pre-embedded support member, so as to form a pre-embedded groove to be poured between the support formwork and the surface of the square column to be reinforced;

[0009] S4, detecting the installation accuracy of the support formwork and determining whether it meets the construction process requirements;

[0010] If the construction process requirements are met, the pre-embedded groove to be poured is poured according to the set pouring process;

[0011] If the construction process requirements are not met, the installation accuracy of the support formwork is calibrated by adjusting the reinforcing members until the construction process requirements are met;

[0012] S5, after the pouring construction is completed, the reinforcing members and the support formwork are sequentially removed according to the installation sequence.

[0013] Optionally, before S1, S0 is also included: pre-treating the surface of the square column to be reinforced according to the construction process requirements; wherein, the pre-treatment method specifically includes:

[0014] The surface of the square column to be reinforced should be sanded and cleaned.

[0015] And / or, obtain the deviation between the surface of the square column to be reinforced and the reference surface set in the construction drawings, and obtain the calibration parameters of the embedded support.

[0016] Optionally, in step S1, the design dimensions and / or installation dimensions of the embedded support components on the surface of the square column to be reinforced in the construction drawings are adjusted according to the calibration parameters of the embedded support components.

[0017] Optionally, the installation spacing between two adjacent reinforcement components is less than 400mm, and the installation spacing between the lowest reinforcement component and the construction reference surface is less than 200mm.

[0018] Optionally, in step S3, the method for reinforcing the support template with the reinforcement component specifically includes:

[0019] Several reinforcing strips are arranged on the side of the support template away from the square column to be reinforced, according to the set bending resistance strength.

[0020] Several sets of back ribs are installed along the extension direction of the reinforcing strip on the side away from the support template according to the set reinforcement rules. Several sets of fixing holes are opened at both ends of the back ribs according to the design dimensions of the construction drawings.

[0021] The fixed anchor rods are sequentially passed through the fixing holes on the two sets of back rib surfaces located on the same axis, and the back ribs are locked to the parts of the fixed anchor rods to be reinforced using fasteners, thereby reinforcing the support template.

[0022] Optionally, the reinforcing strip is configured as a steel-wood keel, wherein the steel-wood keel is provided with square timber and steel frame from the inside out.

[0023] Optionally, the back rib is a hollow square steel, and the fixing hole on the surface of the back rib is an elongated hole.

[0024] Optionally, the fixed anchor bolt is configured as a threaded bolt;

[0025] The fastener is configured as a snap fastener and is snapped onto the outer periphery of the threaded rod.

[0026] Optionally, in step S4, the method for detecting the installation accuracy of the support formwork and determining whether it meets the construction process requirements specifically includes:

[0027] Construct the basic construction model of the support formwork according to the construction drawings;

[0028] According to the construction drawings and the on-site construction conditions, several measuring stations are set up on the edge of the support formwork. Measuring tools are installed at each measuring station to obtain the actual installation parameters of the support formwork in real time, and a construction comparison model is generated based on the actual installation parameters of the support formwork.

[0029] The calibration values ​​of the construction comparison model are generated based on the basic construction model;

[0030] According to the construction process requirements, the calibration value of the construction comparison model is divided into any one of the set error intervals to obtain the installation accuracy level of the corresponding support template. Then, the calculated installation accuracy level of the support template is compared with the level set in the construction drawings.

[0031] If the installation accuracy level of the support formwork is consistent with the level set in the construction drawings, then the installation accuracy of the support formwork is determined to meet the construction process requirements.

[0032] If the installation accuracy level of the support formwork is inconsistent with the level set in the construction drawings, it is determined that the installation accuracy of the support formwork does not meet the construction process requirements.

[0033] Optionally, the measuring tool measures the verticality of any set of the support templates and / or the installation spacing between the support templates located on opposite sides.

[0034] The beneficial effects that this invention can produce include:

[0035] 1. The quick-release square column reinforcement construction method simplifies and simplifies the construction process by using standardized prefabricated structural components (such as embedded supports, steel-wood joists, hollow square steel back braces, etc.) and a modular installation process. Traditional methods rely on professional carpenters for square timber cutting, round pipe splicing, and multi-layer binding, which is time-consuming, labor-intensive, and difficult to guarantee accuracy. In this method, all components are prefabricated according to the construction drawings, and on-site positioning and quick connection (such as bolts and clips) are only required according to the instructions. For example, embedded supports are directly installed after calibration parameter adjustment, support formwork uses tongue and groove splicing or bolt connection, and reinforcement components are quickly locked with fixed anchor rods and clips. This process not only reduces construction steps but also lowers the technical threshold for workers. Ordinary workers can be trained and put to work, reducing reliance on highly skilled carpenters. In addition, the modular design allows for parallel operation of various processes, such as installing reinforcement components simultaneously while building support formwork, further shortening the construction period.

[0036] 2. In traditional square timber reinforcement systems, the square timber is prone to deformation and damage after use, with a reuse rate of less than 20%. Furthermore, disassembly of spliced ​​round pipes is difficult, resulting in a high loss rate. This method utilizes steel-wood joists and hollow square steel back ribs, which are robust, durable, and have high bending strength. After disassembly, they can be reused with only simple cleaning and maintenance. For example, the steel frame of the steel-wood joist protects the internal square timber, reducing wear; the hollow square steel back ribs are lightweight and high-strength, and the fixing holes are designed as elongated slots, facilitating reinstallation after fine-tuning. In addition, the support formwork uses steel formwork or plywood coated with a release agent, which does not easily adhere to concrete during disassembly, extending its service life.

[0037] 3. Traditional square timber reinforcement systems have limited bending resistance and are prone to bulging due to lateral pressure from concrete, resulting in dimensional deviations or uneven surfaces in the columns. This method utilizes a combination of high-strength steel-timber joists and hollow square steel back braces, along with a scientifically spaced arrangement (reinforcement spacing <400mm, bottom spacing <200mm), to form a rigid support network. The steel frame of the steel-timber joists enhances resistance to deformation, while the hollow square steel back braces are secured with anchor rods and clips, ensuring a tight fit between the support formwork and the square column surface. Simultaneously, verticality and spacing are monitored in real-time during installation, and deviations are dynamically adjusted using a calibration model, keeping the formwork installation accuracy within ±2mm. Layered and segmented construction (each layer 300-500mm) combined with optimized vibration compaction effectively reduces air bubbles and voids, resulting in concrete columns with precise dimensions and a smooth surface.

[0038] 4. This method aligns with green building principles by reducing material waste and improving resource utilization. Traditional processes generate significant construction waste from discarded timber and pipes, while the prefabricated components used in this method are recyclable, reducing timber consumption and carbon emissions. For example, the lifespan of steel-timber framing can be more than five times that of traditional timber, and the steel is recyclable. Furthermore, modular design reduces on-site cutting and welding operations, lowering noise and dust pollution. The use of measuring tools (such as laser rangefinders) and BIM models during construction optimizes resource allocation and avoids over-procurement.

[0039] 5. This method introduces digital technologies (such as BIM modeling and total station surveying) to construct an intelligent calibration system. During the support formwork installation phase, data is collected in real time at survey stations to generate a construction comparison model, which is then compared with the foundation model to determine the accuracy level by classifying error ranges. If the deviation exceeds the allowable range, the system automatically prompts for adjustment of the reinforcement positions, forming a closed-loop quality control. For example, when the verticality deviation exceeds 1%, the system suggests fine-tuning the position of the back brace fixing holes or increasing the density of the reinforcement strips. This dynamic calibration mechanism avoids the blind reliance on manual experience in traditional processes, ensuring traceability of construction quality. Simultaneously, all measurement data and adjustment records are stored in a database to provide reference for subsequent projects, achieving knowledge accumulation and process optimization.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Currently, in basic building construction, formwork reinforcement is a crucial step in ensuring the quality of concrete forming. Traditional reinforcement techniques, using a combination of square timber and round pipes, were once widely used, but with the development of the construction industry, their drawbacks have become increasingly apparent. In contrast, the quick-release square column reinforcement construction method demonstrates numerous technological innovations and practical advantages. Therefore, see [reference needed]. Figure 1 As shown, this invention proposes a quick-release square column reinforcement construction method, including the following steps: Precast structural components and reinforcement operation instructions are configured according to the construction drawings. The precast structural components include embedded support components 2, support templates 3, reinforcement strips 4, back ribs 5, fixed anchor rods 7, and fixing components 8. Each component has multiple specifications and dimensions associated with other components, stored in a database as standard parts; this facilitates subsequent retrieval of the corresponding specifications of precast structural components from the database according to the design dimensions of the construction drawings to generate the reinforcement operation instructions; the operators install the precast structural components onto the surface of the square column 1 to be reinforced according to the reinforcement operation instructions; wherein, the reinforcement operation instructions are configured as follows:

[0046] Step 0: Pre-treat the surface of the square column 1 to be reinforced according to the construction process requirements; the pre-treatment method specifically includes: grinding and cleaning the surface of the square column 1 to be reinforced; and / or obtaining the deviation between the surface of the square column 1 to be reinforced and the reference surface set in the construction drawings, so as to obtain the calibration parameters of the embedded support 2.

[0047] The above-mentioned sanding and cleaning operations mainly include: using an electric sander with appropriate sandpaper, sanding from the top of the column to the bottom at a uniform speed, ensuring even sanding pressure and avoiding over- or under-sanding in any area. After sanding, use a high-pressure blower to thoroughly remove surface dust. For oil stains, use a special cleaning agent to wipe them, ensuring no oil residue remains on the column surface. For loose particles, carefully remove them with a scraper or other tools, then clean again with a blower to ensure the column surface is flat and clean, meeting the requirements for subsequent construction. This enhances the adhesion between the subsequent materials and the column surface, and prevents impurities from affecting construction accuracy and quality.

[0048] In obtaining calibration parameters, a high-precision total station or laser rangefinder is first selected. Calibration and debugging are required before use to ensure the accuracy of the measurement data. Then, measurement markers are set at key locations such as the four corners of the column and the midpoint of each side. The distance and angular deviation between the surface of the column to be reinforced (1) and the reference surface set in the construction drawings are measured from multiple angles and directions. For each measurement point, multiple measurements are performed and the average value is taken to reduce measurement error. The measurement data is processed using professional calculation software or manual calculation to accurately obtain the calibration parameters of the embedded support component (2), which serves as an important basis for subsequent adjustments to the installation dimensions. During the measurement process, detailed records are kept of the original data, measurement time, and personnel information for each measurement point. This allows for verification of the measurement data by acceptance personnel after the measurement is completed, ensuring the accuracy and reliability of the data.

[0049] Step 1, such as Figure 2 As shown, embedded support components 2 are installed on the surface of the column to be reinforced 1 according to the construction drawings. During actual installation, to ensure installation accuracy, the design dimensions and / or installation dimensions of the embedded support components 2 on the surface of the column to be reinforced 1 in the construction drawings can be adjusted based on the calibration parameters of the embedded support components 2. Specifically, professional drawing software (such as AutoCAD) is used to precisely adjust the design dimensions and / or installation dimensions of the embedded support components 2 on the surface of the column to be reinforced 1 in the construction drawings, and important parameters are marked on the adjusted construction drawings to guide subsequent construction, ensuring the accuracy of the construction and compliance with design requirements.

[0050] In the above process, when installing the embedded support component 2, firstly, based on the adjusted construction drawings, select the corresponding specifications, model, and material of the embedded support component 2 from the standard parts set in the database to ensure that it meets the design requirements and relevant standards and specifications. Simultaneously, check the surface of the selected embedded support component 2 for defects such as cracks and deformation. If any problems are found, replace it with a qualified embedded support component 2 in a timely manner. Then, based on the adjusted construction drawings again, mark the installation position of the embedded support component 2 on the surface of the square column 1 to be reinforced (using methods such as chalk lines or laser marking instruments) to ensure accurate positioning. During installation, use measuring instruments such as levels and theodolites for auxiliary positioning to ensure that the horizontal and vertical errors of the embedded support component 2 are within the allowable range. For the installation of multiple embedded support components 2, adjust the installation spacing and arrangement neatness according to the relationship between adjacent embedded support components 2 to ensure the overall installation effect. Then, use high-strength bolts or welding to firmly fix the embedded support component 2 to the surface of the square column to be poured. If bolts are used for fixing, ensure that the tightening torque of the bolts meets the design requirements. Use a torque wrench to tighten the bolts and record the tightening operation. If welding is used, ensure the welding quality. The weld height, length, and appearance quality must meet relevant standards. After welding, conduct weld quality inspections, such as visual inspection and ultrasonic testing. After installation, check the stability of the embedded support 2 to ensure that it can withstand the loads of subsequent construction.

[0051] Step Two, as follows Figure 2 and Figure 3 As shown, a support formwork 3 is erected on the outer periphery of the pre-embedded support component 2. Specifically, firstly, a support formwork 3 of the appropriate specification is selected from the standard components set in the database according to the design dimensions and construction requirements of the construction drawings, such as plywood or steel formwork. The thickness, strength, and rigidity of the support formwork 3 must meet the construction requirements, and the surface should be flat and smooth, without defects such as warping or deformation. Before use, the support formwork 3 is cleaned and coated with a release agent to facilitate its subsequent removal and ensure the forming quality of the square column surface.

[0052] In the above process, starting from the bottom of the column 1 to be reinforced, the support formwork 3 is erected sequentially from bottom to top. Adjacent support formwork 3s are joined using tongue-and-groove joints or bolt connections, ensuring tight joints. Sealing strips or sponge strips can be applied to the joints to prevent grout leakage during concrete pouring. During the erection of the support formwork 3, reinforcement components can be used simultaneously to ensure its stability and verticality. Furthermore, after each layer of support formwork 3 is erected, its verticality and dimensions must be checked promptly. Any deviations must be adjusted immediately until the work passes inspection before proceeding to the next step to avoid the accumulation of errors.

[0053] Step 3, as follows Figure 3As shown, several sets of reinforcing members are used to fix the support templates 3 located on both sides opposite to the square column 1 to be reinforced to the outer periphery of the embedded support members 2, so as to form a pre-embedded groove for pouring between the support templates 3 and the surface of the square column 1 to be reinforced; wherein the installation spacing between two adjacent reinforcing members is less than 400mm, and the installation spacing between the bottommost reinforcing member and the construction reference surface is less than 200mm. During the installation process, measuring tools such as tape measures are used to measure the spacing to ensure that the spacing meets the requirements. For parts where the spacing does not meet the requirements, adjustments are made in a timely manner to ensure the stability and uniformity of the reinforcement. At the same time, attention should be paid to the installation sequence and direction of the reinforcing members to ensure that the installation is neat and standardized.

[0054] In the above, the reinforcement method for the support formwork 3 includes: arranging several reinforcing strips 4 on the side of the support formwork 3 away from the square column 1 to be reinforced according to the set bending strength; installing several sets of back ribs 5 along the extension direction of the reinforcing strips 4 away from the support formwork 3 according to the set reinforcement rules, with several sets of fixing holes 6 opened at both ends of the back ribs 5 according to the design dimensions of the construction drawings; passing the fixing anchor rods 7 sequentially through the fixing holes 6 on the surface of the two sets of back ribs 5 and located on the same axis, ensuring that the threaded rods pass through the fixing holes 6 perpendicularly to avoid tilting or bending; and using the fixing parts 8 to lock the back ribs 5 to the part to be reinforced of the fixing anchor rods 7, thereby achieving the reinforcement of the support formwork 3.

[0055] In the above, the reinforcing strip 4 is set as a steel-wood keel, and the steel-wood keel is set with square timber and steel frame from the inside to the outside. For example, square timber is installed in the steel frame of polygonal structure to improve the bending resistance of square timber to concrete column during the pouring construction, avoid the phenomenon of mold expansion, and ensure the quality of solid forming. At the same time, the reinforcing strip 4 is a prefabricated component, which has high reusability compared with traditional square timber, can reduce material waste and save construction costs.

[0056] In the above, the back rib 5 is a prefabricated hollow square steel, which facilitates construction and avoids installation deviation caused by the excessive weight of the back rib 5 during installation; and the fixing holes 6 on the surface of the back rib 5 are made into long strip holes according to the design dimensions of the construction drawings, so as to make fine adjustments to the installation position of the fixing anchor 7 during the installation process.

[0057] In the above, the fixed anchor rod 7 is a prefabricated component, equipped with a corresponding series of threaded rods for each size specification of the fixing hole 6 to ensure that the performance indicators such as diameter, length, and strength meet the design requirements. The fixing component 8 adopts a snap-fit, preferably a butterfly snap-fit, which is snapped onto the outer circumference of the threaded rod. By tightening the nut on the snap-fit, the back rib 5 is locked in the part of the fixed anchor rod 7 to be reinforced. When tightening the nut, a torque wrench should be used to control the tightening torque to ensure that the tightening degree of each snap-fit ​​is consistent, so that the back rib 5 is evenly stressed, thereby achieving a firm reinforcement of the support formwork 3.

[0058] Step 4: Check the installation accuracy of the support formwork 3 and determine if it meets the construction process requirements. If it meets the requirements, pour the pre-embedded trench according to the set pouring process. If it does not meet the requirements, adjust the reinforcement components to calibrate the installation accuracy of the support formwork 3 until it meets the requirements. During the calibration process, measurements and data processing should be repeated, and the calibration effect should be monitored in real time to ensure the effectiveness of the calibration work.

[0059] The method described above for detecting the installation accuracy of the support formwork 3 and determining whether it meets the construction process requirements includes: constructing a basic construction model of the support formwork 3 according to the construction drawings. This basic construction model is generated using professional Building Information Modeling (BIM) software or other 3D modeling software, such as Revit or Tekla. Then, based on the construction drawings and on-site construction conditions, several measuring stations are set up along the edges of the support formwork 3. The location and number of measuring stations should comprehensively reflect the installation status of the support formwork 3. Generally, measuring stations are set up at the four corners of the support formwork 3, the midpoints of each edge, and key locations. Simultaneously, the measuring stations are marked to ensure accurate location during measurement. Measuring tools are installed at each measuring station to obtain the actual installation parameters of the support formwork 3 in real time. These parameters are then input into data analysis software to generate a construction comparison model. During the generation of the construction comparison model, the data is screened, organized, and analyzed to remove abnormal data, ensuring that the construction comparison model accurately reflects the actual installation status of the support formwork 3. Calibration values ​​for the construction comparison model are generated based on the basic construction model. These calibration values ​​are set as the difference between each parameter in the basic construction model and the construction comparison model. The calibration values ​​reflect the degree of deviation between the actual installation and the design requirements, providing an important basis for judging the installation accuracy of the support formwork 3. According to the construction process requirements, the calibration values ​​of the construction comparison model are divided into several predetermined error intervals to obtain the corresponding installation accuracy level of the support formwork 3. Each error interval corresponds to one installation accuracy level of the support formwork 3. The calculated installation accuracy level of the support formwork 3 is then compared with the level set in the construction drawings. If the installation accuracy level of the support formwork 3 matches the level set in the construction drawings, the installation accuracy of the support formwork 3 is determined to meet the construction process requirements; if the installation accuracy level of the support formwork 3 does not match the level set in the construction drawings, the installation accuracy of the support formwork 3 is determined to not meet the construction process requirements.

[0060] In the above process, measuring tools are used to measure the verticality of any set of support templates 3 and / or the installation spacing between support templates 3 located on opposite sides. Specifically, measuring tools can include a total station, laser rangefinder, plumb line, etc. The verticality of any set of support templates 3 is measured using a total station, and the verticality deviation is determined by measuring the angle between the surface of the support template 3 and the plumb line. The installation spacing between support templates 3 located on opposite sides is measured using a laser rangefinder to ensure that the spacing meets design requirements. During the measurement process, the operating procedures of the measuring tools must be strictly followed to ensure the accuracy and reliability of the measurement data. Simultaneously, the measurement data must be recorded in real time, including measurement time, measurement point location, and measurement data.

[0061] In the above-described process, according to the established pouring procedure, concrete is poured in layers and sections, starting from one side of the pre-embedded groove to be poured. The height of each layer should not be too high, generally controlled at around 300-500mm, to ensure the concrete is compacted. During pouring, a vibrator is used to compact the concrete; the vibration time and intensity should be moderate to avoid over-vibration or under-vibration. The vibrator should be inserted quickly and withdrawn slowly, penetrating 50-100mm into the next layer of concrete to ensure a tight bond between the upper and lower layers. During pouring, the deformation of the support formwork 3 should be carefully observed; if any abnormalities are found, pouring should be stopped immediately and appropriate reinforcement measures should be taken.

[0062] Step 5: After the pouring construction is completed, the reinforcement components and support formwork 3 should be dismantled in an orderly manner according to the installation sequence. Specifically, the reinforcement components and support formwork 3 can only be dismantled after the strength of the poured concrete reaches the design requirement for dismantling (generally determined by strength testing of test blocks cured under the same conditions). Dismantling too early may damage the square column structure, while dismantling too late will affect the construction progress and the reuse of the formwork. During the dismantling operation, first remove the fasteners 8 (clamps) and the fixed anchor rods 7 (threaded rods), and then remove the back ribs 5, reinforcing strips 4, and support formwork 3 in sequence. During the dismantling process, appropriate tools should be used to avoid excessive force that could damage the support formwork 3 and the square column. The dismantled support formwork 3 and reinforcement components should be cleaned promptly to remove concrete residue, dust, and other impurities from the surface. For support formwork 3, check for damage and repair it promptly if any is found; for reinforcement components, check for loose or deformed connections and address any problems immediately. After cleaning and repair, the support template 3 and reinforcement components should be sorted and stored in a flat and dry place to prevent them from getting damp, deformed or damaged, so that they can be used next time.

[0063] Example 2

[0064] This application also provides a BIM-based quick-release square column reinforcement design method, including the following steps: S1. Based on the BIM model, perform three-dimensional modeling of the square column 1 to be reinforced, and generate a standard prefabricated component library, which includes embedded support 2, support template 3, reinforcement strip 4, back rib 5, fixed anchor rod 7, and clips; S2. Divide the reinforcement construction process according to the construction drawings, and associate the construction process parameters of each process in the BIM model; S3. Call the standard components in the prefabricated component library, and perform adaptive combination of support template 3 and reinforcement components through the BIM parametric configuration module to generate multiple reinforcement schemes; S4. Perform real-time accuracy detection on the reinforcement scheme based on the BIM model. If the accuracy meets the standard, output the pouring path; otherwise, adjust the reinforcement component parameters and regenerate the reinforcement scheme; S5. After the concrete strength meets the standard, simulate the demolition sequence in the BIM model according to the preset demolition logic, and output the quick-release command.

[0065] In the above, in S1, the parametric configuration of the standard prefabricated components includes: the installation dimensions of the embedded support 2 are dynamically adjusted based on the deviation calibration parameters of the square column surface in the BIM model; the spacing constraint of the reinforcing strip 4 is that the adjacent spacing is less than 400mm, and the distance of the bottom reinforcing part from the reference surface is less than 200mm; the fixing hole 6 of the back rib 5 is set as an elongated hole, and the installation path of the fixed anchor 7 is automatically matched by the BIM rule engine.

[0066] In S3, the adaptive combination includes: calling the functional classifier in the prefabricated component library according to the construction process parameters to generate the closed path of the support template 3; performing interval matching or interpolation calculation on the splicing segments of the reinforcement components based on the BIM constrained configuration module, and optimizing the combination result through the conflict detection algorithm.

[0067] In S4, the accuracy detection includes: setting up virtual measuring stations in the BIM model, collecting verticality and spacing data of the support template 3 in real time; comparing the actual parameters with the design model, dividing the error range and generating calibration values; if the calibration value exceeds the threshold, triggering a parameter adjustment command.

[0068] In S5, the generation of quick-release instructions includes: generating the demolding path in reverse order of "clasp → fixed anchor rod 7 → back rib 5 → reinforcing strip 4 → support template 3"; simulating the demolding process through the BIM visualization module, and outputting demolding tools and operation guidelines.

[0069] In the above process, a full-size 3D model of the square column 1 to be reinforced is created using BIM technology. The actual contour data of the column surface is obtained through laser scanning or total station measurements and compared with the reference surface in the design drawings to calculate surface deviations (such as flatness error and verticality deviation), generating calibration parameters for the embedded support component 2. These parameters are fed back to the BIM model in real time, dynamically adjusting the installation dimensions of the embedded support component 2 (such as positioning coordinates and bolt hole spacing) to ensure precise fit between the prefabricated components and the actual square column surface. The prefabricated component library includes standardized components such as embedded support component 2, support template 3, reinforcing strip 4 (steel-wood keel), back rib 5 (hollow square steel), fixed anchor rod 7, and clips. Each component has multiple pre-set specifications and dimensions (such as the length of back rib 5 and the spacing of reinforcing strip 4) and is associated with construction process parameters (such as bending strength and bolt torque). For example, parameters such as the steel frame thickness of the steel-wood keel and the cross-sectional dimensions of the square timber can be automatically matched to the square column dimensions through BIM parametric units, avoiding errors and waste from on-site cutting in traditional processes.

[0070] In the above, based on the construction drawings, the reinforcement process is divided into key procedures such as surface pretreatment → installation of embedded support components 2 → construction of support formwork 3 → installation of reinforcement components → accuracy inspection → concrete pouring → formwork removal. In the BIM model, each procedure is associated with specific process parameters: Pretreatment: clearly defined grinding and cleaning standards (e.g., surface roughness Ra value) and deviation measurement accuracy (±1mm); Installation: horizontal error of embedded support components 2 ≤ 2mm, reinforcement component spacing < 400mm, bottom reinforcement component distance from the reference surface < 200mm; Inspection: verticality deviation threshold is 1%, relative spacing error between two side formworks ± 2mm. By digitally binding procedures and parameters, standardized operating guidelines are formed, avoiding reliance on experience in manual operations, and providing a data foundation for subsequent construction simulation and quality traceability.

[0071] In the above, standard parts from the prefabricated component library are called, and the support template 3 and reinforcement components are intelligently combined through the BIM parametric configuration module. Specifically, this includes: 1) Closed path generation: Based on the cross-sectional dimensions of the square column, the splicing method of the support template 3 (such as tongue and groove splicing or bolt connection) is automatically matched to generate the closed outline of the template to ensure the tightness of the joint; 2) Reinforcement component spacing calculation: Based on the lateral pressure of concrete, combined with parameters such as the height of the square column and the pouring speed, the optimal spacing between the reinforcement strip 4 and the back rib 5 is dynamically calculated to avoid the local strength deficiency that may be caused by the traditional "equidistant arrangement"; 3) Conflict detection: The spatial position of the reinforcement components, the embedded support 2, and the template joint is analyzed by the BIM engine, and the path of the fixed anchor rod 7 is automatically adjusted (such as the position offset of the long strip hole of the back rib 5) to eliminate component interference problems.

[0072] In the above process, virtual surveying stations (such as the four corners of the template and the midpoints of each side) are set up in the BIM model to simulate the actual measurement path of a total station or laser rangefinder, and to collect data such as template verticality, spacing deviation, and diagonal error in real time. The system compares the measured parameters with the design model and classifies the accuracy level according to the error range: error ≤ 1mm: accuracy meets the standard, and the pouring path is directly output (such as layered pouring height of 300-500mm, vibration point spacing of 400mm); 1mm < error ≤ 3mm: a parameter adjustment command is triggered, and calibration is achieved by fine-tuning the position of the back rib 5 fixing hole 6 or increasing the density of the reinforcing strip 4; error > 3mm: the template is automatically prompted to be reinstalled to avoid the risk of template bulging due to accumulated deviations. This closed-loop calibration mechanism replaces the traditional rough mode of manual string line measurement, controls the installation accuracy within ±2mm, and generates a visual error report to provide data support for quality acceptance.

[0073] In the above, once the concrete strength reaches the design requirements (e.g., through the compressive strength test of test blocks under the same conditions), the BIM model simulates the demolition process in reverse order: "first the reinforcement components, then the formwork; first the top, then the bottom": 1) Path planning: dismantle the clips in sequence → fix the anchor rods 7 → back ribs 5 → reinforcing strips 4 → support the formwork 3, to avoid structural damage due to a chaotic demolition sequence; 2) Tool matching: recommend special tools (such as torque wrenches and demolding pry bars) according to the component connection method, and mark the key points of operation (such as the clips need to be loosened symmetrically when removing them to avoid deformation of the formwork on one side); 3) Risk warning: simulate possible collision points during the demolding process (such as the embedded bolts and the edge of the formwork), and remind the operators to avoid them in advance to reduce safety hazards.

[0074] A BIM-based quick-release square column reinforcement design system includes: a BIM modeling module for constructing a 3D model of the square column 1 to be reinforced and generating a standard prefabricated component library; a process management module for dividing construction processes and associating process parameters; an adaptive combination module for calling the prefabricated component library to generate reinforcement schemes and optimizing combination paths through conflict detection algorithms; an accuracy calibration module for real-time detection of scheme accuracy based on virtual survey station data and dynamic adjustment of parameters; and a quick-release simulation module for generating demolding instructions and visually simulating the demolding process.

[0075] The BIM modeling module includes: a prefabricated component parametric unit, which dynamically adjusts the size of the embedded support 2 according to the calibration parameters of the square column surface; and a constraint configuration unit, which sets construction constraint rules such as the spacing of the reinforcing strip 4 and the position of the fixing hole 6 of the back rib 5.

[0076] The adaptive combination module includes: a function classifier calling unit, which matches prefabricated components according to the closed path of the support template 3; and a conflict handling unit, which resolves conflicts in the matching of splicing segment intervals through a rule engine.

[0077] The accuracy calibration module includes: a virtual test station generator, which marks key test points in the BIM model; and an error analysis unit, which compares the measured data with the design model and generates a calibration report.

[0078] The quick-release simulation module includes: a demolding path planner that generates demolding steps in reverse order; and a tool matching unit that recommends specialized tools and operating procedures based on the demolding instructions.

[0079] In the above, the BIM modeling module includes prefabricated component parametric units and constrained configuration units. The prefabricated component parametric units dynamically adjust the three-dimensional dimensions of the embedded support 2 based on the calibration parameters of the square column surface (such as deviation and deviation of internal and external corners) to achieve precise adaptation of "one column, one design". The constrained configuration units are used to preset construction rules such as the spacing of the reinforcing strips 4 and the position of the fixing holes 6 of the back ribs 5 (such as the spacing between adjacent reinforcing parts < 400mm) to ensure that the model automatically meets the specifications and reduces human design errors.

[0080] In the above, the process management module is used to break down the construction process into quantifiable standard operating units. Each unit is associated with information such as process standards, personnel configuration, and material usage. For example, the "support formwork 3 erection" process automatically associates parameters such as formwork type (steel formwork or plywood), splicing method, and release agent application standards, and pushes them to the construction team through a mobile APP, realizing a seamless connection between "construction according to drawings" and "acceptance according to standards".

[0081] In the above, the adaptive combination module includes a function classifier calling unit and a conflict handling unit. The function classifier calling unit automatically selects matching prefabricated components based on the closed path requirements of the support formwork 3 (e.g., when the side length of the square column is >800mm, steel formwork is preferred over plywood). The conflict handling unit resolves component splicing conflicts through a rule engine (e.g., the position of the bolt holes of the back rib 5 and the embedded support 2 are offset), and automatically generates adjustment schemes (e.g., extending the length of the back rib 5 or adding auxiliary reinforcement components), avoiding the inefficiency of traditional manual adjustment.

[0082] In the above, the accuracy calibration module includes a virtual measurement station generator and an error analysis unit. The virtual measurement station generator is used to mark key inspection points in the BIM model, simulate the on-site measurement process, and discover potential deviations in advance (such as excessive spacing at the bottom of the template). The error analysis unit is used to compare the measured data with the design model and generate a report containing deviation values, the scope of influence, and calibration suggestions, which supports construction personnel to quickly locate problems and make adjustments, forming a quality control closed loop of "inspection-analysis-calibration".

[0083] In the above, the quick dismantling simulation module includes a dismantling path planner and a tool matching unit. The dismantling path planner generates a visual dismantling animation based on the reverse logic of the component installation sequence, guiding workers to operate according to the process and reducing damage to the formwork caused by blind dismantling (the formwork breakage rate in traditional processes is about 10%-15%, while this system can reduce it to below 3%). The tool matching unit recommends special tools according to the component connection type (bolts, clips, welding) to avoid violent dismantling, and records the tool usage frequency to optimize equipment scheduling.
