Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building structures, and in particular relates to a large-area wall formwork support system. BACKGROUND

[0002] Wall formwork support systems are common template support structures in construction engineering, and their main function is to provide temporary support and fixation for concrete walls to ensure the size, shape and quality of the walls. Traditional wall formwork support systems are usually composed of wooden supports, steel pipe fasteners or special metal support pieces, among which the use of metal support pieces is the most widespread. Such support systems have the advantages of high support strength and reusability, but there are still some problems to be improved.

[0003] Firstly, the existing metal support system is mostly supported by single columns, which is not evenly distributed in stress, and is prone to local deformation or damage, affecting the overall stability. Secondly, the existing support system can only be adjusted vertically in height, and cannot meet the multi-angle adjustment requirements in complex engineering environments. In addition, the existing products have limitations in large template support and multi-layer wall support, and are difficult to adapt to the construction needs of large buildings and high-rise buildings.

[0004] In addition, the existing support system also has some problems in installation and disassembly, anti-toppling, locking, etc. For example, the cumbersome installation and disassembly process can easily increase the labor intensity of workers, which is not conducive to improving construction efficiency; lack of reliable anti-toppling design, prone to tilting or even collapse in bad weather such as strong wind and rain, threatening the safety of construction personnel; unable to effectively lock the support height, prone to unstable height when subjected to external forces.

[0005] In summary, the existing large-area wall formwork support system has the problems of insufficient support strength, limited adjustment capacity, poor anti-toppling performance, and inconvenient installation and disassembly, which is difficult to meet the increasingly complex and diverse needs of current construction engineering. Therefore, it is urgent to develop a new large-area wall formwork support system with better performance and stronger applicability. SUMMARY

[0006] Therefore, the present application provides a large-area wall formwork support system to solve the problem of limited adjustment capacity of the existing large-area wall formwork support system.

[0007] The present application is implemented as follows:

[0008] The application provides a large-area wall formwork support system, which comprises a support frame, adjustable support columns, transverse connecting beams, longitudinal reinforcing rods, formwork fixing devices, adjusting mechanisms, locking devices and anti-toppling assemblies; the support frame comprises a base and upright columns, the base has a rectangular structure, and the upright columns are vertically and fixedly connected to the four corners of the base; the adjustable support columns are arranged inside the support frame, the lower ends of the adjustable support columns are fixedly connected to the base, and the upper ends extend above the top of the upright columns; the transverse connecting beams are horizontally arranged between adjacent two upright columns, and the two ends of each transverse connecting beam are fixedly connected to the upright columns; the longitudinal reinforcing rods are vertically arranged between adjacent two adjustable support columns, and the two ends of each longitudinal reinforcing rod are fixedly connected to the adjustable support columns; the formwork fixing devices are arranged at the top ends of the adjustable support columns and used for fixing wall formworks; the adjusting mechanisms are arranged on the adjustable support columns and used for adjusting the height of the adjustable support columns; the locking devices are arranged on the adjusting mechanisms and used for locking the height of the adjustable support columns after adjustment; and the anti-toppling assemblies are arranged outside the support frame and used for increasing the stability of the support system.

[0010] Firstly, the system adopts multiple adjustable support columns as the main support, forms a stable three-dimensional space frame structure through the cooperation of the transverse connecting beams and the longitudinal reinforcing rods. This support mode can not only effectively disperse the stress and enhance the overall carrying capacity, but also can adjust the height and inclination angle of the support columns to meet the diversified needs under complex construction environments. Compared with single-column support, the system is obviously more reliable in terms of deformation resistance and overturning resistance.

[0012] In addition, the formwork fixing devices are arranged at the top ends, including fixing seats, pressing plates and fastening bolts, which can firmly clamp the wall formworks on the support system. This fixing mode can not only ensure the accuracy of the position of the formworks, but also can withstand a large external force without displacement, thereby ensuring the quality of the wall structure. Compared with the traditional simple placement or buckle fixing, the fixing device greatly improves the carrying capacity of the support system.

[0013] In order to enhance the overall stability of the support system, the anti-toppling assembly is arranged outside the column, including the inclined strut, the ground anchor and the adjusting nut. This design not only effectively resists external forces such as wind and rain, reducing the risk of overturning, but also can adapt to different construction environments by adjusting the angle and stress of the inclined strut. Compared with the existing simple support feet, the anti-toppling mechanism has obvious advantages in wind resistance and earthquake resistance.

[0014] In addition, the present application also innovatively designs the key components such as the transverse connecting beam and the longitudinal reinforcing rod.

The transverse reinforcement structure: the transverse reinforcement is arranged at the middle position of the adjacent adjustable support column, which is composed of: 1) a fixed sleeve with a diameter of 90mm and a thickness of 5mm, which can slide up and down on the outside of the adjustable support column; 2) a connecting rod with a diameter of 30mm and a thickness of 4mm, which is hinged at both ends with two fixed sleeves; 3) a fastening bolt with a diameter of 16mm and a length of 60mm, which passes through the fixed sleeve and is locked on the adjustable support column. By adjusting the fastening bolt, the fixed sleeve can be locked at the appropriate position, and the connecting rod can connect the adjacent adjustable support columns together, further improving the transverse stiffness and stability of the entire support system.

[0083] In summary, the large-area wall formwork support system provided by the present application has reasonable component structure and size parameters calculated strictly, which can meet the needs of large-scale construction. The support frame is composed of a base and a column, and the height of the column is adjustable. The adjustable support column adopts a screw lifting mechanism, and the height can be adjusted flexibly. The formwork fixing device has a compact structure and can quickly and stably fix the large-area wall formwork. The transverse connecting beam and the longitudinal reinforcing rod are designed reasonably, which improves the overall stiffness of the system. The anti-toppling assembly and the transverse reinforcement further enhance the stability of the support system. Through careful design and optimization of each component, the reliability and practicality of the entire large-area wall formwork support system are ensured.

[0084] Embodiment:

[0085] A high-rise building project is currently under construction for concrete wall construction. The project is located in a coastal area, and the wall height reaches 12 meters, with an average width of 4 meters. Due to the large size of the wall, the traditional single-column support method cannot meet the requirements, and local deformation and overall tilting problems may occur. Therefore, the construction team decides to use the large-area wall formwork support system proposed by the present application for wall support.

[0086] According to the actual situation on site, the specific implementation scheme of the support system is as follows:

[0087] 1. Design of support frame and adjustable support column: the support frame adopts a rectangular frame structure and is made of 40x40x3mm square steel pipes. The base size is 3500mmx1800mm, and there are six columns arranged at the four corners and the middle. Each column is 12.2 meters high.

[0088] The adjustable support column adopts an outer cylinder-inner cylinder structure, with an outer cylinder diameter of 140mm and a thickness of 4mm, and an inner cylinder diameter of 120mm and a thickness of 5mm. The inner cylinder can slide up and down in the outer cylinder, and the height can be adjusted by the adjusting mechanism.

[0089] The adjustment mechanism includes a vertically mounted screw, nut, and handwheel. The screw has a diameter of 30mm and a length of 1200mm. Its lower end is rotatably connected to the bottom of the outer cylinder, and its upper end passes through the top of the outer cylinder and is fixed to the handwheel. The nut is fixed to the bottom of the inner cylinder and is threaded into the screw. By rotating the handwheel, the screw can be rotated, thereby driving the inner cylinder to slide up and down, thus adjusting the height of the support column.

[0090] The locking device consists of a locking bolt and a locking nut. The locking bolt passes horizontally through the side wall of the outer cylinder, pressing the inner cylinder against it; the locking nut is fitted over the outer end of the locking bolt for securing. By tightening the locking nut, the inner cylinder can be locked in the adjusted position, preventing changes in height.

[0091] As per the project requirements, the support system consists of 12 adjustable support columns arranged in two rows and six columns. Each support column has an effective adjustment range of 9.8-12.2 meters, which meets the actual wall height requirements.

[0092] 2. Design of the formwork fixing device: The formwork fixing device includes a fixing seat, a pressure plate, and fastening bolts. The fixing seat adopts a U-shaped structure, welded to the top of the inner cylinder, with the U-shaped opening facing upwards to accommodate the bottom edge of the wall formwork. The pressure plate adopts an L-shaped structure, with its horizontal part placed on the top surface of the wall formwork and its vertical part corresponding to the fixing seat. The fastening bolts pass through the vertical part of the pressure plate and the fixing seat to clamp and fix the wall formwork.

[0093] The dimensions of the template fixing device are as follows: the fixing seat is 400mm wide, 150mm high vertically, and 10mm thick; the horizontal part of the pressure plate is 450mm long, the vertical part is 300mm high, and the thickness is 12mm; the fastening bolts are M20 bolts with a length of 200mm.

[0094] Based on the thickness and stiffness characteristics of the wall formwork, mechanical calculations and analysis show that the maximum load-bearing capacity of the fixing device can reach 85kN, which is sufficient to support a 4-meter-wide and 12-meter-high concrete wall formwork.

[0095] 3. Design of the transverse connecting beam: The transverse connecting beam adopts an I-beam steel structure, with main beam dimensions of 340mm × 200mm × 10mm. Triangular reinforcing ribs are installed at the connection between the web and flange of the main beam to improve the bending stiffness of the beam. Connecting plates are provided at both ends and fixed to the columns by welding.

[0096] Multiple [items] are spaced apart along the length of the main beam. The system includes adjustment holes spaced 200mm apart. These holes allow fastening bolts to pass through, enabling adjustment of the installation position of the transverse connecting beams and improving adaptability.

[0097] According to the calculation, the maximum horizontal distance between each column in a 12-meter high wall support should not exceed 3.6 meters. Therefore, in this project, 12 transverse connecting beams with a span of 3.5 meters are used. By adjusting the hole settings, flexible installation can be achieved according to the actual column spacing.

[0098] 4. Design of longitudinal reinforcing rod: The longitudinal reinforcing rod adopts a telescopic rod structure composed of an outer tube and an inner tube. The outer tube has a diameter of 80 mm and a thickness of 4 mm, and the inner tube has a diameter of 70 mm and a thickness of 5 mm. The inner tube can slide up and down in the outer tube, and the length can be changed by adjusting the locking sleeve.

[0099] The locking sleeve is sleeved at the connection between the outer tube and the inner tube, and can lock the inner tube in the adjusted position by rotating the M16 thread. A fixed ear plate is welded at the end of the outer tube and the inner tube, which is used for fixed connection with the adjustable support column.

[0100] According to the actual situation of this project, the horizontal distance between adjacent adjustable support columns is 3.5 meters, and the maximum height difference can reach 400 mm. Through calculation, the effective length of the longitudinal reinforcing rod should be between 3800-4200 mm. Therefore, the length of the telescopic rod body is set to 4000 mm during production, with an adjustment range of ±200 mm, which can meet the needs of various support height differences.

[0101] 5. Design of anti-toppling assembly: The anti-toppling assembly includes diagonal struts, ground anchors, and adjusting nuts. The diagonal strut is made of a round steel pipe, with the upper end connected to the top of the column through a hinge, and the lower end connected to the adjusting nut through a threaded connection. The ground anchor is made of a threaded steel bar, buried in the ground, with the top exposed to the ground and provided with a connecting hole. The adjusting nut is hinged with the connecting hole of the ground anchor through a pin.

[0102] According to the wind load and the geometric size of the support frame, through mechanical calculation and analysis, the length of the diagonal strut should be 7.8 meters, and the angle θ with the ground should be 53°. The rotation range of the adjusting nut is ±120 mm, which can adjust the inclination angle and stress of the diagonal strut, and adapt to different construction environments.

[0103] To ensure the pullout bearing capacity of the ground anchor, according to the soil conditions on site, a threaded steel bar with a diameter of 30 mm and a length of 800 mm is used. The top of the ground anchor is exposed to the ground by 300 mm and is hinged with the diagonal strut. By rotating the adjusting nut, the stress state of the diagonal strut can be adjusted, and the stability of the entire support system can be enhanced.

[0104] 6. Design of base and leveling device: The base adopts a welded rectangular frame structure made of 50×50×5 mm angle steel. There is a vertical downward support leg at each corner and intermediate position of the frame bottom, and a​​​ The leveling plate is connected to the support legs via an M24 thread and can be rotated to adjust the levelness of the support system.

[0105] According to engineering specifications, the base dimensions are designed to be 3500mm × 1800mm × 150mm. By adjusting the adjusting plates on the support legs, a ground height difference of ±50mm can be compensated, ensuring the stability of the entire support system.

[0106] 7. Design of the transverse reinforcement: To further enhance the overall rigidity of the support system, a transverse reinforcement is installed at the midpoint between two adjacent adjustable support columns. This reinforcement includes a fixing sleeve, a connecting rod, and fastening bolts.

[0107] The fixing sleeve adopts The round tube is designed to fit over the adjustable support column and slide up and down. The connecting rod uses... The round steel bar is hinged at both ends to two fixing sleeves. The fastening bolts are M16 bolts, which pass through the fixing sleeves to lock it in a designated position on the adjustable support column.

[0108] By adjusting and locking the position of the fixing sleeve, the length of the connecting rod can be varied to accommodate different support column spacing requirements. This reinforcement design effectively enhances the overall rigidity and stability of the entire support system.

[0109] 8. On-site installation and commissioning: Based on the above design scheme, the specific installation steps for the large-area wall formwork support system in this project are as follows:

[0110] (1) First, level the ground at the construction site to ensure that the foundation is flat and free of depressions. Then place the base frame and adjust the leveling plate on the support legs to achieve the horizontal alignment of the base.

[0111] (2) Install the adjustable support column onto the base and adjust the height of the support column to 12 meters using the adjustment mechanism. Then fix the support height using the locking device.

[0112] (3) Install the transverse connecting beam. First, weld the connecting plate to the column, and then fix the beam to the connecting plate with the fastening bolts. Adjust the position of the beam appropriately according to the actual column spacing and lock it.

[0113] (4) Install longitudinal reinforcing rods between adjacent support columns. First, weld the fixing lugs to the support columns, then adjust the length of the telescopic rods and fix them with locking sleeves.

[0114] (5) Install the anti-tipping components. First, bury the ground anchor in the ground, then connect the lower end of the diagonal brace to the ground anchor using an adjusting nut. The upper end is then connected to the top of the column via a hinge. Adjust the tilt angle of the diagonal brace by rotating the adjusting nut.

[0115] (6) Finally, install the formwork fixing device. First, weld the fixing seat to the top end of the inner cylinder, then place the bottom edge of the wall formwork in the fixing seat, and finally clamp and fix it with the pressing plate and tightening bolts.

[0116] During the entire installation process, strict operation according to design parameters and necessary safety protection measures should be taken. For example, during the height adjustment of the support column, two workers should cooperate, one operating the hand wheel and the other monitoring the displacement of the support column. When fixing the formwork, it should be temporarily fixed first and then finally locked to ensure safety.

[0117] After the installation is completed, the construction team needs to debug and check the entire support system. First, measure the actual height of each support column and compare it with the design value. If the error exceeds ±10mm, it should be adjusted again. Second, check whether each connection part is firm and reliable, and whether the tightening bolts are tightened in place. Third, observe the overall deformation of the support system under the action of self-weight to ensure that the deformation is within the allowable range. Finally, check the overall stability of the support system under simulated load to ensure safety and reliability.

[0118] Only after careful installation and debugging can the support system perform as expected in actual construction. Construction personnel should strictly follow the design requirements and conduct all necessary checks to prevent any safety hazards.

[0119] 9. Performance verification and analysis: To verify the actual performance of the designed large-area wall formwork support system, the construction team set up a test sample on site and conducted a series of performance tests. The results show that the support system meets the design requirements in all performance indicators, as follows:

[0120] (1) Support strength and stability: Simulated loads are used to apply vertical and horizontal loads to the support system. The test results show that at a height of 12 meters, the support system can withstand a vertical load of 108kN and a horizontal load of 32kN, far exceeding the maximum load requirement in actual wall construction. At the same time, under the action of the load, the overall deformation of the support system is very small, and there is no local support point overload or overall inclination, which reflects good overall stability.

[0121] (2) Adjustability and adaptability: Through testing, it is found that the adjustable support column of the support system can be continuously adjusted within the range of 9.8-12.2 meters, meeting the needs of different wall heights. At the same time, the optimized design of the transverse connecting beam and the longitudinal reinforcing rod also enables the support system to adapt to the change of wall width within 3.0-4.0 meters. In addition, the adjustment mechanism of the anti-toppling assembly can fine-tune the inclination angle of the inclined strut within ±120mm, enhancing the system's adaptability to uneven foundations.

[0122] (3) Installation convenience: Compared with traditional support systems, this support system is more convenient to install and disassemble. The rapid adjustment of support column height, flexible adjustment of crossbeam position, and length change of telescopic rod greatly simplify the complexity of on-site installation. In addition, the horizontal leveling of the base and the automatic calibration of the anti-toppling assembly further improve the installation efficiency.

[0123] (4) Use safety: In the test under simulated strong wind conditions, the support system did not tilt or collapse, and the anti-toppling assembly played a good role. At the same time, the formwork fixing device can reliably fix the wall formwork on the support system, ensuring the stability of the formwork position and preventing it from slipping under external force. In addition, the design of the locking device can effectively prevent accidental changes in support height during use, maximizing the safety of construction personnel.

[0124] Overall, through on-site testing, the designed large-area wall formwork support system meets or exceeds the expected design requirements in various performance indicators, and can well adapt to complex construction environments and needs. Compared with traditional support systems, this system has significantly improved in support strength, adjustability, safety, and other aspects, providing strong technical support for high-quality concrete wall construction.

[0125] The following table summarizes the main technical parameters of the support system of the invention:

[0126]

[0127]

[0128] The above is the specific implementation of the large-area wall formwork support system of the invention. The system has been fully verified in on-site tests for its excellent technical performance, and can effectively solve the problems existing in existing support systems, providing reliable technical support for construction engineering. The construction team will strictly follow the design parameters and installation steps to fully promote the application of the support system in subsequent wall construction, to ensure the quality and safety of the project.

[0129] Specifically, the principle of the invention is: 1. The support structure design of multiple adjustable support columns. The system uses multiple adjustable support columns as the main support component, and by setting inner and outer cylinder structures that can slide up and down between the base and the column, it realizes the adjustability of the support height. This support method not only effectively disperses the load and improves the overall carrying capacity, but also can flexibly adjust the support height according to the on-site construction needs, adapting to complex engineering environments. Compared with traditional single-column support, this multi-point support structure design has obvious advantages in carrying capacity, stability, and adaptability.

[0130] 2. The matching design of the adjusting mechanism and the locking device. A special adjusting mechanism is provided on the adjustable support column, including a hand wheel driven screw-nut structure, which can conveniently and quickly adjust the height of the support column. At the same time, a locking device is also provided on the adjusting mechanism, which can reliably fix the adjusted support height position through the cooperation of the locking bolt and the locking nut. The cooperative design of the adjusting mechanism and the locking device not only improves the flexibility of the support system, but also enhances its overall stability and safety. Under the action of external force, the adjusting mechanism can ensure that the support height does not change, avoiding safety hazards.

[0131] 3. The load-bearing design of the formwork fixing device. A special formwork fixing device is provided at the top of the adjustable support column, including a fixing seat, a pressing plate and a tightening bolt. This fixing method can firmly clamp the wall formwork on the support system, ensuring the accuracy and stability of the formwork position. Compared with simple placement or buckle fixing, the fixing device can withstand larger external forces without displacement, thereby better ensuring the quality of the wall structure. At the same time, the load-bearing capacity of the formwork fixing device is closely related to the stability of the adjustable support column, and there is a certain mechanical relationship between them, which can be optimized by calculation and analysis.

[0132] 4. The stability design of the anti-toppling assembly. In order to enhance the overall stability of the support system, the anti-toppling assembly is provided on the outside of the column, including a diagonal brace, a ground anchor and an adjusting nut. This design can effectively resist the action of wind and rain and other external forces, reducing the risk of overturning of the entire support system. The length and inclination angle of the diagonal brace have a certain mechanical relationship with the height of the support frame and the position of the ground anchor, and reasonable size parameters can be determined through calculation and analysis to ensure that the anti-toppling assembly can provide sufficient support force. At the same time, the design of the adjusting nut can also realize the fine adjustment of the angle of the diagonal brace, further improving the stability of the support system.

[0133] 5. The optimization design of the transverse connecting beam and the longitudinal reinforcing rod. The transverse connecting beam adopts an I-shaped steel structure, which can improve the transverse stiffness and load-bearing capacity; adjusting holes are provided on the beam body, which can adjust its installation position according to the actual situation, improving the adaptability. While the longitudinal reinforcing rod adopts a telescopic rod structure, which can quickly realize length change through the adjustment of the locking sleeve, meeting the needs of different support height differences. These optimization designs not only enhance the overall stability of the system, but also improve its versatility and flexibility.

[0134] The key technical designs of the above aspects jointly constitute the core principle of the large-area wall formwork support system proposed by the application. Among them, the multiple adjustable support columns as the main bearing components improve the overall support strength and stability; the cooperation design of the adjusting mechanism and the locking device ensures the flexible adjustment and reliable fixation of the support height; the bearing design of the formwork fixing device ensures the accurate positioning and stability of the wall formwork; the stable design of the anti-toppling assembly enhances the ability of the support system to resist external force; and the optimization design of the transverse connecting beam and the longitudinal reinforcing rod further improves the versatility and adaptability of the system.

[0135] These technical innovations fully embody the effective solutions proposed by the application for the problems existing in the existing large-area wall formwork support system. The support system not only has obvious progress in bearing capacity, adjustability, stability, safety and the like, but also has great advantages in construction efficiency, worker safety and the like. The improvement of the comprehensive performance enables the large-area wall formwork support system of the application to better adapt to the increasingly complex and diverse demands of current construction engineering, and provides strong technical support for high-quality construction.
