Description

Technical Field

[0001] This invention relates to the field of building construction technology, and more specifically, to a method for constructing inclined columns. Background Technology

[0002] Inclined columns, as a special type of structural element, not only serve the structural function of connecting different floors compared to traditional vertical columns, but also showcase a unique aesthetic. As urban construction focuses increasingly on large-scale integrated stadiums, inclined columns will see wider application. Their stability and construction quality directly impact the safety and lifespan of the entire stadium. Therefore, research on inclined column construction techniques is particularly crucial.

[0003] However, in actual construction, the strength and stability of the formwork support system are difficult to control during formwork erection and concrete pouring, causing great obstacles to construction. Summary of the Invention

[0004] In view of this, the present invention proposes a method for constructing inclined columns, which aims to solve the problem that it is difficult to control the strength and stability of the formwork support system during the existing construction of inclined columns, including the positioning of the formwork and the concrete pouring process.

[0005] This invention proposes a method for constructing inclined columns. The construction process of this method is as follows: base treatment → application of release agent to formwork → hoisting and erection of formwork → correction of formwork tilt angle → formwork fixing → wetting the formwork with water → checking the axial displacement and cross-sectional dimensions of the formwork → pouring concrete → formwork removal.

[0006] Furthermore, in the above-mentioned inclined column construction method, after the formwork is erected, the initial displacement data of each measuring point is recorded. During the pouring process, the deformation of the formwork is observed. The displacement data of each measuring point of the formwork is recorded once at each first preset time interval, and once at each second preset time interval after the pouring is completed, until the settlement value of the two adjacent layers is less than the preset stable value; the settlement value of the two adjacent layers is the difference between the displacement data of the two adjacent records; based on the displacement data of each measuring point, it is determined whether there is an early warning prompt for the deformation of the formwork and the type of early warning.

[0007] Furthermore, in the above-mentioned inclined column construction method, if a warning is issued during concrete pouring due to formwork deformation and the warning type is yellow settlement warning, the concrete pouring of the inclined column is suspended, the formwork support system is restored to its original support state, and displacement data of each measuring point of the formwork is recorded every third preset time interval to determine the deformation state after the formwork support is restored, until the warning is lifted, at which point pouring continues; wherein, the third preset time interval is shorter than the first preset time interval. If a warning is issued during concrete pouring due to formwork deformation and the warning type is red settlement warning, the concrete pouring work is suspended, the number of formwork supports is increased, and displacement data of each measuring point of the formwork is recorded every fourth preset time interval to determine the deformation state after the formwork support is restored, until the warning is lifted, at which point pouring continues; wherein, the fourth preset time interval is shorter than the first preset time interval.

[0008] Furthermore, the aforementioned inclined column construction method, specifically the determination of whether there is an early warning for template deformation and the type of early warning based on the displacement data of each measuring point, includes: plotting a displacement data-time curve based on the displacement data of each measuring point to determine whether there is abnormal data; if there is abnormal data in the displacement data of each measuring point, then removing the abnormal data; based on the displacement data after removing the abnormal data, performing data analysis to determine the single settlement and cumulative settlement, and determining whether there is an early warning for template deformation and the type of early warning; if the single settlement is greater than 2mm, or the cumulative settlement is greater than 5mm, then it is determined to be a yellow settlement warning; if the single settlement is greater than 5mm, or the cumulative settlement is greater than 10mm, then it is determined to be a red settlement warning.

[0009] Furthermore, in the above-mentioned inclined column construction method, after the support frame is erected, the initial tilt angle of each measuring point is recorded. During the pouring process, the change of the formwork angle is observed, and the tilt angle of each measuring point is recorded once every five preset time intervals. After the pouring is completed, the tilt angle is recorded once every six preset time intervals until the change of the tilt angle between two adjacent layers is less than the preset stable angle. Based on the tilt angle of each measuring point, it is determined whether there is an early warning prompt for the change of the formwork angle and the type of early warning.

[0010] Furthermore, in the above-mentioned inclined column construction method, if an early warning is issued during the concrete pouring process due to changes in the formwork angle, and the warning type is a yellow settlement warning, then the concrete pouring of the inclined column is suspended, the formwork support system is restored to its original support state, and the tilt angle of each measuring point of the formwork is recorded every seventh preset time interval to determine the deformation state after the formwork support is restored, until the warning is lifted, at which point the pouring continues; wherein, the seventh preset time interval is shorter than the fifth preset time interval. If an early warning is issued during the concrete pouring process due to changes in the formwork deformation, and the warning type is a red settlement warning, then the concrete pouring work is suspended, the number of formwork supports is increased, and the tilt angle of each measuring point of the formwork is recorded every eighth preset time interval to determine the deformation state after the formwork support is restored, until the warning is lifted, at which point the pouring continues; wherein, the eighth preset time interval is shorter than the fifth preset time interval.

[0011] Furthermore, the aforementioned inclined column construction method, specifically the determination of whether there is an early warning and the type of early warning based on the inclination angle of each measuring point, includes: plotting an inclination angle-time curve based on the inclination angle of each measuring point to determine whether there is abnormal data; if there is abnormal data in the inclination angle data of each measuring point, then removing the abrupt data; based on the inclination angle data after removing the abrupt data, performing data analysis to determine the single inclination angle change and the cumulative inclination angle change, and determining whether there is an early warning and the type of early warning for the change in template angle; if the single inclination angle change is greater than 0.1°, or the cumulative inclination angle change is greater than 0.3°, then it is determined to be a yellow angle warning; if the single inclination angle change is greater than 0.2°, or the cumulative inclination angle change is greater than 0.5°, then it is determined to be a red angle warning.

[0012] Furthermore, the above-mentioned inclined column construction method involves reinforcing the joints at the junctions of columns with different cross-sections, and using reusable template sealing plugs to seal the template holes.

[0013] Furthermore, in the above-mentioned inclined column construction method, the formwork support specifically includes: setting a first formwork support on the outer side of the inclined inner corner of the inclined side formwork to support the inclined side formwork; setting a second formwork support on the inner side of the inclined inner corner of the opposite side formwork to support the opposite side formwork; and setting a third formwork support on the outer side of the inclined inner corner of the inclined side formwork to support the joint of the inclined side formwork.

[0014] Furthermore, in the above-mentioned inclined column construction method, before pouring concrete and after the formwork is fixed, the second formwork support is removed and taken out from between the formwork.

[0015] The inclined column construction method provided by this invention improves the efficiency of inclined column construction, and reduces the construction difficulty while ensuring the accuracy of the formwork, achieving multiple benefits. It provides stronger technical support for the construction of large-scale comprehensive stadiums and brings greater economic benefits, solving the problems of difficulty in controlling the strength and stability of the formwork support system during concrete pouring and the positioning of the formwork in existing inclined column construction methods. In addition, this inclined column construction method also has the following technical effects: First, the use of building engineering formwork support devices and formwork supports ensures that the strength, rigidity, and stability of the inclined column formwork structure meet the construction requirements. No bursting or bulging of the formwork occurred during the concrete pouring process of the inclined column, ensuring that the formwork system is solid and stable.

[0016] Secondly, the formwork system is convenient, rapid, and has good overall integrity. The civil engineering formwork connection device accelerates formwork splicing, reduces the difficulty of splicing, ensures tight sealing of formwork joints to prevent grout leakage, and improves construction quality.

[0017] Third, it has a high degree of informatization. Displacement sensors are used to monitor the deformation of the formwork in real time, allowing for accurate early detection of anomalies in the formwork system and preventing serious construction accidents such as formwork instability and collapse.

[0018] Fourth, it extends the service life of formwork. By using reusable formwork sealing plugs, the problem of formwork being unable to be reused due to holes during use is effectively solved, increasing the number of times formwork can be used, reducing construction costs, and preventing grout leakage caused by formwork holes from affecting the load-bearing capacity of the concrete structure.

[0019] Fifth, it offers high construction efficiency and shortens the construction period. The application of this construction method can further improve construction efficiency, ensure project quality, and provide strong support for the construction of various inclined column structures.

[0020] Sixth, it has a wide range of applications and great potential for further development. This construction method can be widely applied to the construction of irregularly shaped columns in various multi-purpose stadiums, improving the speed of formwork construction while ensuring construction quality, and providing more referable cases for future construction of multi-purpose stadiums.

[0022] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] See Figure 1 The figure shows a flowchart of the inclined column construction method provided in this embodiment of the invention. As shown in the figure, the construction process of the inclined column construction method is as follows: base treatment → application of release agent to the formwork → hoisting and positioning of the formwork → correction of the inclination angle of the formwork → fixing the formwork → wetting the formwork with water → checking the axial displacement and cross-sectional dimensions of the formwork → pouring concrete → removing the formwork.

[0024] In this embodiment, before the base treatment, material acceptance can be carried out first. In particular, it is necessary to inspect the formwork, tie bolts and square timber to ensure that the components used are qualified.

[0025] like Figure 1 As shown, the specific treatment of the base layer is as follows: clean the column foundation reinforcement and mark the axis and edge lines to achieve positioning.

[0026] In this embodiment, when the hoisting template is in place, it can be assembled by installing the numbered parts, and the tilt angle of the template can be corrected, with an allowable deviation of less than or equal to 1°.

[0027] See Figure 2 This is a schematic diagram of the inclined column formwork support structure provided in an embodiment of the present invention. As shown in the figure, on the outer side of the inclined inner angle of the inclined side formwork 1 (e.g. Figure 2 As shown on the right side, a first template support 2 is set up to position and support the inclined template 1. In particular, it can provide support at the bottom of the template and the support angle can be flexibly adjusted to ensure that the template can maintain an inclined state at a fixed angle for a long time, which facilitates the reinforcement and construction of the template.

[0028] Specifically, there can be multiple first template supports 2, providing support at multiple points at different locations above and below the inclined side to ensure the stability of the inclined template 1. For example... Figure 2 As shown, there are two first template supports 2, arranged side by side along the inclined direction of the inclined template 1, which can be supported by a support section (such as...). Figure 2 As shown in the upper left corner, the inclined side template 1 is supported by two spaced-apart support points. Of course, along the length of the inclined side template 1 (as shown in the upper left corner), the support points are also provided. Figure 2 Multiple first template supports 2 (as shown in the direction perpendicular to the paper) can also be provided to further ensure the stability of the inclined template 1. The first template support 2 can be a template support disclosed in Chinese Publication No. CN217028097U. The first fixed support member 3 can provide a support surface facing the inclined template 1 and arranged parallel to it, so that the top support (not shown in the figure) of the first template support 2 can be fixedly supported on the support surface. The support rod 21 of the first template support 2 can be arranged perpendicular to the support surface. Of course, the support surface can also be arranged at other angles, such as a vertical surface; this embodiment does not impose any limitations on it. In this embodiment, the top support end of the support rod 21 (e.g., the direction perpendicular to the paper) is... Figure 2 The angle of the support body 22 (shown at the upper left end) is adapted to the inclined template 1, thus supporting the inclined template 1. The first fixed support 3 can be an angle-adjustable base, comprising two rotatably connected support plates 31. One support plate 31 rests on the ground, while the other support plate 31 supports the support rod 21 and can be connected to a top support. A length adjustment rod 32 is provided between the two support plates 31, with its two ends hinged to the two support plates 31 respectively, used to adjust the angle between the two support plates 31, thereby adjusting the support angle of the first template support 2, i.e., the support angle of the support surface.

[0029] Continue to see Figure 2 On the inner side of the inclined inner angle of the opposite side template 4 of the inclined side template 2 (e.g. Figure 2 As shown on the right side, a second template support 5 is installed to position and support the reverse template 4. In particular, it can provide support at the bottom of the template and the support angle can be flexibly adjusted to ensure that the template can maintain an inclined state at a fixed angle for a long time, which facilitates the reinforcement and construction of the template.

[0030] Specifically, there can be multiple second template supports 5, which are located along the length of the opposite template 4 (e.g., Figure 2The side-by-side and spaced arrangement (perpendicular to the paper) further ensures the stability of the reverse side formwork 4. The second formwork support 5 can be a formwork support device for construction engineering disclosed in Chinese Publication No. CN212802563U, the difference being that the clamping member can be inclined or angle-adjustably mounted on the threaded rod, with the setting angle adapted to the inclination angle of the formwork, thus achieving support for the reverse side formwork 4.

[0031] Before construction, the positions of the first formwork support 2 and the second formwork support 5 must be marked. The spacing between the first formwork support 2 and the second formwork support 5 can be less than or equal to 1.5 meters. After determining the positions, adjust the angles of the first formwork support 2 and the second formwork support 5, hoist the formwork, and use the first formwork support 2 and the second formwork support 5 for support and reinforcement. After the formwork is reinforced and fixed, remove the second formwork support 5. That is, before pouring concrete and after the formwork is fixed, remove the second formwork support and take it out from between the formwork. The first formwork support 2 can be removed at the same time as the formwork is removed.

[0032] See Figure 3 This is a schematic diagram of the structure of the inclined column formwork splice support provided in an embodiment of the present invention. As shown in the figure, on the outer side of the inclined inner angle of the inclined side formwork 1 (e.g. Figure 3 (As shown on the right) A third template support 6 is installed to support the joint of the inclined side template 1.

[0033] Specifically, the third formwork support 6 can be a formwork connection device for civil engineering construction disclosed in Chinese Publication No. CN220377855U. The joint of the inclined side formwork 1 can be the joint between two plates arranged vertically, or the joint between two adjacent inclined side formworks 1 in the length direction. The second fixed support 7 can provide a support surface facing the inclined side formwork 1 and arranged parallel to the inclined side formwork 1, so that the base 61 of the third formwork support 6 can be fixedly supported on the support surface, and the fixing cylinder 62 of the third formwork support 6 can be arranged perpendicular to the support surface. In this embodiment, the support end of the fixing cylinder 62 (e.g., Figure 3 The positioning mechanism 63 (shown at the upper left end) is arranged at an angle that matches the inclined side template 1, enabling support for two adjacent inclined side templates 1. The second fixed support 7 can be an angle-adjustable base, and its structure can be referenced from the first fixed support 3; therefore, the structure of the second fixed support 7 will not be described in detail here.

[0034] In this embodiment, the template fixing specifically involves installing column hoops and tightening tie bolts. Specifically, the column hoops can be made of steel, and their spacing can be less than or equal to 600mm. The tie bolts can be 12mm in diameter and can be installed and tightened symmetrically to fix the template.

[0035] To further ensure the stability of the template, preferably, after the template is fixed and before it is moistened with water, the joints at the intersections of columns with different cross-sections can be reinforced and the template holes can be sealed. Specifically, the joint reinforcement at the intersections of columns with different cross-sections can be achieved by filling with square timber. In this embodiment, a reusable template sealing plug can be used to seal the template holes. The reusable template sealing plug can be one disclosed in Chinese Publication No. CN212802562U. It seals the template holes by plugging the plug body, thereby enabling the template to be reused and improving its utilization rate. A plug head at one end of the plug body abuts against the side wall of the template to limit the plug body. Twisting the plug head can rotate the plug body, allowing it to be inserted into or removed from the hole. This facilitates the assembly and disassembly of the template sealing plug, enabling its reuse and increasing the template's service life, while also preventing grout leakage during concrete pouring.

[0036] In this embodiment, the deformation of the formwork needs to be controlled in real time during the concrete pouring process. Preferably, after the formwork is erected, the initial displacement data of each measuring point is recorded. During the pouring process, the deformation of the formwork is observed, and the displacement data of each measuring point of the formwork is recorded once at a first preset time interval. After the pouring is completed, the data is recorded once at a second preset time interval until the settlement value of the two adjacent layers is less than the preset stable value. The settlement value of the two adjacent layers is the difference between the displacement data of the two adjacent records. Based on the displacement data of each measuring point, it is determined whether there is an early warning prompt for the formwork deformation and the type of early warning, so as to avoid accidents such as formwork bursting.

[0037] Specifically, after the formwork is erected, a wire displacement sensor is used to monitor the settlement changes of the formwork structure in real time. The wire displacement sensor converts the linear displacement of the wire into a digital signal output through a high-precision rotary encoder or potentiometer, monitoring the vertical settlement of the formwork structure in real time. Its core advantages are high resolution (up to 0.01mm) and a wide measurement range (0-50mm), suitable for long-term continuous monitoring. A wire displacement sensor with a range matching the expected settlement is selected, and measuring points are installed at key locations such as column foundations and beam-slab junctions. The wire direction must be perpendicular to the formwork surface to avoid collisions with reinforcing bars or construction machinery. The sensor installation height should be 1.5m above the ground for easy observation and maintenance, with a measuring point spacing of 5m. The end of the wire is rigidly connected to the measuring point on the formwork to avoid measurement errors caused by formwork deformation. The displacement sensor is calibrated using a 10mm standard gauge block for static calibration; the error should be <0.1%. Simulated formwork settlement (e.g., applying a known load) is used for dynamic calibration to verify the sensor's response sensitivity.

[0038] In this embodiment, after the template is erected, the initial displacement value (zero point) of each measuring point is recorded immediately. During concrete pouring, data is collected every first preset time interval, for example, every 30 minutes; after pouring, the data is collected every second preset time interval, for example, every hour, until the settlement value of two adjacent layers is less than a preset stable value, which can be 0.1 mm, and monitoring stops when the settlement stabilizes. Displacement changes are recorded in real time through a wireless transmission system. The acceptance criteria table for the wire displacement gauge can be found in Table 1.

[0039] Table 1 Acceptance Standards for Wire Displacement Gauges Serial Number Test items Permissible value (mm) Control measures 1 Single settlement ≤2 Immediate review and adjustment of the support system. 2 Cumulative settlement ≤10 Emergency response plan activated, reinforcement measures implemented. 3 Settlement rate ≤0.5 / h Continuous detection, trend analysis In this embodiment, determining whether there is an early warning for template deformation and the type of early warning based on the displacement data of each measuring point specifically includes: plotting a displacement data-time curve based on the displacement data of each measuring point to determine whether there is abnormal data; if there is abnormal data in the displacement data of each measuring point, the abnormal data is removed; based on the displacement data after removing the abnormal data, data analysis is performed to determine the single settlement amount and the cumulative settlement amount, and to determine whether there is an early warning for template deformation and the type of early warning. If the single settlement amount is greater than 2mm, or the cumulative settlement amount is greater than 5mm, it is determined to be a yellow settlement warning; if the single settlement amount is greater than 5mm, or the cumulative settlement amount is greater than 10mm, it is determined to be a red settlement warning.

[0040] Specifically, settlement-time curves can be plotted based on displacement data from each measuring point to determine if there are any abnormal data, such as abrupt changes. This involves comparing the data with data from adjacent measuring points or other sensors in the same area to rule out instrument errors. The settlement-time curves can also be used to determine whether the settlement trend is linear or accelerating. Furthermore, based on the displacement data after removing abnormal data, data analysis is performed to determine the amount of single-event settlement and cumulative settlement, and to determine if there are any warnings regarding template deformation and the type of warning. This involves tiered warnings; for example, a yellow settlement warning is issued if the single-event settlement is greater than 2 mm or the cumulative settlement is greater than 5 mm; a red settlement warning is issued if the single-event settlement is greater than 5 mm or the cumulative settlement is greater than 10 mm.

[0041] See Figure 4This is a flowchart illustrating the process of handling formwork deformation during concrete pouring, as provided in this embodiment of the invention. As shown, if a yellow settlement warning is issued during concrete pouring due to formwork deformation, the concrete pouring of the inclined column is paused. The formwork support system is restored to its original support state, and displacement data at each measuring point of the formwork is recorded every third preset time interval (e.g., 10 minutes) to determine the deformation state after the formwork support is restored. Pouring continues only after the warning is lifted. The third preset time interval is shorter than the first preset time interval. If a red settlement warning is issued during concrete pouring due to formwork deformation, the concrete pouring is paused. The number of formwork supports is increased, and displacement data at each measuring point of the formwork is recorded every fourth preset time interval to determine the deformation state after the formwork support is restored. Pouring continues only after the warning is lifted. The fourth preset time interval is shorter than the first preset time interval. Both the third and fourth preset time intervals can be 10 minutes or other values; however, the fourth preset time interval is preferably shorter than the third preset time interval.

[0042] Of course, in this embodiment, it is necessary to control the deformation of the formwork, such as the angle change, in real time during the concrete pouring process. Preferably, after the support frame is erected, the initial tilt angle of each measuring point is recorded. During the pouring process, the change of the formwork angle is observed, and the tilt angle of each measuring point is recorded once every five preset time intervals. After the pouring is completed, the tilt angle is recorded once every six preset time intervals until the change of the tilt angle between two adjacent layers is less than the preset stable angle. Based on the tilt angle of each measuring point, it is determined whether there is a warning prompt for the change of the formwork angle and the type of warning.

[0043] Specifically, after the formwork is erected, inclinometer sensors are used to monitor the tilt deformation of the formwork support structure in real time. The inclinometer, through its built-in accelerometer or gyroscope, measures the tilt angle of the support structure relative to the horizontal plane in real time, thereby determining whether the structure has tilted or deformed. Its resolution can reach 0.001°, detecting minute tilts and suitable for real-time tracking of tilt changes during construction. Select an inclinometer with a range covering the expected tilt angle (±0.5°) and a resolution ≤0.01°; choose a waterproof and vibration-resistant model to handle concrete pouring. Install measuring points at easily tilted locations such as the columns, adjustable supports, and scissor brace connection points of the support frame. Arrange one set vertically every two floors and one set horizontally per span. Fix the inclinometer to the surface of the support structure using clamps or magnetic bases, ensuring that the sensor axis is parallel to the structure axis; multiple inclinometers must be in the same plane to form a tilt monitoring network.

[0044] In this embodiment, after the support frame is erected, the initial tilt angle (zero point) of each measuring point is recorded. During concrete pouring, data is collected every 15 minutes; that is, the fifth preset time period can be 15 minutes. After pouring, the data collection frequency is increased to once per hour; that is, the sixth preset time period can be 1 hour, until the structure is stable. Data is uploaded to the monitoring platform in real time using a wireless transmission system. When a single tilt angle change is >0.1° or the cumulative tilt is >0.3°, the measuring points need to be increased and the support system needs to be checked. The inclinometer sensor acceptance criteria table can be found in Table 2.

[0045] Table 2 Acceptance Criteria for Inclinometer Sensors Serial Number Test items Allowed values Control measures 1 Single column tilt angle ≤0.5° Adjustable support height 2 Incline rate ≤0.05° / h Continuous monitoring and trend analysis In this embodiment, determining whether there is a warning and the type of warning based on the tilt angle of each measuring point specifically includes: plotting a tilt angle-time curve based on the tilt angle of each measuring point to determine whether there is abnormal data; if there is abnormal data in the tilt angle data of each measuring point, then removing the abrupt data; based on the tilt angle data after removing the abrupt data, performing data analysis to determine the single tilt angle change and the cumulative tilt angle change, and determining whether there is a warning and the type of warning for the template angle change; if the single tilt angle change is greater than 0.1°, or the cumulative tilt angle change is greater than 0.3°, then it is determined to be a yellow angle warning; if the single tilt angle change is greater than 0.2°, or the cumulative tilt angle change is greater than 0.5°, then it is determined to be a red angle warning.

[0046] Specifically, tilt angle-time curves can be plotted based on the tilt angles of each measuring point to determine whether there is linear growth or abrupt change. Combined with data from adjacent measuring points, the tilt direction (e.g., tilting towards the load side) and symmetry can be analyzed. A tiered early warning system is used: yellow warning: single tilt angle change > 0.1° or cumulative tilt > 0.3°; red warning: single tilt angle change > 0.2° or cumulative tilt > 0.5°. After an early warning is triggered, check whether the support column is subjected to eccentric stress, reinforce the tilted side support, or add diagonal bracing.

[0047] See Figure 5This is a flowchart illustrating the handling of abnormal formwork tilt angles during concrete pouring, as provided in this embodiment of the invention. As shown, if a yellow settlement warning is issued during concrete pouring due to changes in the formwork angle, the concrete pouring for that inclined column is paused. The formwork support system is restored to its original support state, and the tilt angle of each measuring point of the formwork is recorded every seventh preset time interval to determine the deformation state after the formwork support is restored. Pouring continues only after the warning is lifted. The seventh preset time interval is shorter than the fifth preset time interval. If a red settlement warning is issued during concrete pouring due to formwork deformation, the concrete pouring is paused. The number of formwork supports is increased, and the tilt angle of each measuring point of the formwork is recorded every eighth preset time interval to determine the deformation state after the formwork support is restored. Pouring continues only after the warning is lifted. The eighth preset time interval is shorter than the fifth preset time interval.

[0048] This inclined column construction method is applicable to inclined column construction, particularly suitable for large public buildings, commercial complexes, stadiums, and other projects with stringent requirements for inclined column structures. Furthermore, it is also suitable for inclined column construction in high-rise and super high-rise buildings, effectively addressing the challenges of difficult and precise formwork erection for inclined columns in high-rise building construction. In addition, this inclined column construction method also has broad application prospects in infrastructure construction such as bridges and tunnels where inclined column structures are required.

[0049] This inclined column construction method combines four published patent applications with information technology to form an innovative approach. This method aims to improve the efficiency and formwork precision of inclined column construction while reducing its construction difficulty, achieving multiple benefits. It provides stronger technical support for the construction of large-scale comprehensive stadiums and brings greater economic benefits.

[0050] In summary, the inclined column construction method provided in this embodiment improves the efficiency of inclined column construction, and reduces its construction difficulty while ensuring the accuracy of the formwork, achieving multiple benefits. It provides stronger technical support for the construction of large-scale comprehensive stadiums and brings greater economic benefits, solving the problems of difficulty in controlling the strength and stability of the formwork support system during concrete pouring and the formwork positioning during existing inclined column construction. In addition, this inclined column construction method also has the following technical effects: First, the use of building engineering formwork support devices and formwork supports ensures that the strength, rigidity, and stability of the inclined column formwork structure meet the construction requirements. No bursting or bulging of the formwork occurred during the concrete pouring process of the inclined column, ensuring that the formwork system is solid and stable.

[0051] Secondly, the formwork system is convenient, rapid, and has good overall integrity. The civil engineering formwork connection device accelerates formwork splicing, reduces the difficulty of splicing, ensures tight sealing of formwork joints to prevent grout leakage, and improves construction quality.

[0052] Third, it has a high degree of informatization. Displacement sensors are used to monitor the deformation of the formwork in real time, allowing for accurate early detection of anomalies in the formwork system and preventing serious construction accidents such as formwork instability and collapse.

[0053] Fourth, it extends the service life of formwork.
