Description

Technical Field

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

[0002] The wall formwork support system is a common formwork support structure in construction projects. Its 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 brackets, steel pipe fasteners or special metal supports, among which metal supports are the most widely used. This type of support system has the advantages of high support strength and reusability, but there are also some problems that need to be improved.

[0003] First, the existing metal support systems are mostly single-column supports, which are unevenly distributed and prone to local deformation or damage, affecting overall stability. Second, the existing support systems are usually only able to adjust the vertical height, which cannot meet the multi-angle adjustment requirements in complex engineering environments. In addition, existing products have limitations in large formwork support and multi-layer wall support, making it 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-dumping, locking, etc. For example, the cumbersome installation and disassembly process easily increases the labor intensity of workers, which is not conducive to improving construction efficiency; the lack of reliable anti-dumping design makes it easy to tilt or even collapse in severe weather such as strong winds and rains, threatening the safety of construction workers; the support height cannot be effectively locked, and it is easy to become highly unstable when subjected to external forces.

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

[0006] In view of this, the present invention provides a large-area wall formwork support system, which is used to solve the problem of limited adjustment capability of existing large-area wall formwork support systems.

[0007] The present invention is achieved in that:

[0008] The present invention provides a large-area wall formwork support system, which includes: a support frame, an adjustable support column, a transverse connecting beam, a longitudinal reinforcing rod, a formwork fixing device, an adjustment mechanism, a locking device and an anti-dumping assembly; the support frame includes a base and a column, the base is a rectangular structure, and the columns are vertically fixedly connected at the four corners of the base; the adjustable support column is arranged inside the support frame, the lower end of the adjustable support column is fixedly connected to the base, and the upper end extends above the top of the column; the transverse connecting beam is horizontally arranged between two adjacent columns, and the two ends of the transverse connecting beam are respectively fixedly connected to the columns; the longitudinal reinforcing rod is vertically arranged between two adjacent adjustable support columns, and the two ends of the longitudinal reinforcing rod are respectively fixedly connected to the adjustable support columns; the formwork fixing device is arranged at the top end of the adjustable support column for fixing the wall formwork; the adjustment mechanism is arranged on the adjustable support column for adjusting the height of the adjustable support column; the locking device is arranged on the adjustment mechanism for locking the adjusted height of the adjustable support column; the anti-dumping assembly is arranged on the outside of the support frame for increasing the stability of the support system.

[0009] The technical effects of a large-area wall formwork support system provided by the present invention are as follows: The large-area wall formwork support system proposed by the present invention has achieved significant progress and innovation in solving the problems existing in the prior art.

[0010] First, the system uses multiple adjustable support columns as the main support, and forms a stable three-dimensional space frame structure through the cooperation of transverse connecting beams and longitudinal reinforcement rods. This support method can not only effectively disperse the force and enhance the overall bearing capacity, but also adjust the height and inclination angle of the support column to meet the diverse needs in complex construction environments. Compared with single column support, this system is significantly more reliable in terms of anti-deformation and anti-overturning.

[0011] Secondly, the present invention sets a special adjustment mechanism and locking device on the adjustable support column. The adjustment mechanism uses a screw-nut structure driven by a hand wheel to quickly and conveniently adjust the height of the support column; while the locking device can reliably fix the adjusted height position to avoid height instability under the action of external force. This design not only improves the flexibility of the support system, but also enhances its stability and safety.

[0012] In addition, the present invention is provided with a special template fixing device at the top, including a fixing seat, a pressure plate and a fastening bolt, which can firmly clamp the wall template on the support system. This fixing method can not only ensure the accuracy of the template position, but also 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 bearing capacity of the support system.

[0013] In order to enhance the overall stability of the support system, the present invention sets an anti-dumping assembly on the outside of the column, including a diagonal brace, a ground anchor and an adjustment nut. This design can not only effectively resist external forces such as wind and rain and reduce the risk of overturning, but also adapt to different construction environments by adjusting the angle and force of the diagonal brace. Compared with the existing simple support feet, the anti-dumping mechanism has obvious advantages in wind resistance and earthquake resistance.

[0014] In addition, the present invention also makes innovative designs on key components such as the transverse connecting beam and the longitudinal reinforcing rod. For example, the transverse connecting beam adopts an I-shaped steel structure, and an adjustment hole is set on the beam body, so that its installation position can be adjusted according to actual conditions to improve adaptability; the longitudinal reinforcing rod adopts a telescopic rod body structure, and the length can be quickly changed by adjusting the locking sleeve to meet the needs of different support height differences. These optimized designs further enhance the versatility and flexibility of the system.

Transverse reinforcement structure: The transverse reinforcement is set in the middle of the adjacent adjustable support columns and consists of the following parts: 1) Φ90mm×5mm fixing sleeve, which can slide up and down outside the adjustable support column; 2) Φ30mm×4mm connecting rod, with two ends hinged to the two fixing sleeves; 3) M16×60mm fastening bolt, which passes through the fixing sleeve and is locked on the adjustable support column. By adjusting the fastening bolt, the fixing sleeve can be locked in the appropriate position, and the connecting rod connects the adjacent adjustable support columns together, further improving the lateral stiffness and stability of the entire support system.

[0083] In summary, the components of the large-area wall formwork support system provided by the present invention have reasonable structures, and the size parameters have been strictly calculated, which can meet the needs of large-scale building construction. The support frame consists of a base and a column, and the column height is adjustable; the adjustable support column adopts a screw lifting mechanism, and the height can be flexibly adjusted; the formwork fixing device has a compact structure and can quickly and stably fix the large-area wall formwork; the horizontal connecting beam and the longitudinal reinforcement rod are reasonably designed to improve the overall rigidity of the system; the anti-dumping assembly and the horizontal reinforcement piece further enhance the stability of the support system. Through the careful design and optimized combination of each component, the reliability and practicality of the entire large-area wall formwork support system are ensured.

[0084] Example:

[0085] A high-rise building project is currently undergoing concrete wall construction. The project is located in a coastal area, with a wall height of 12 meters and an average width of 4 meters. Due to the large size of the wall, the traditional single column support method is difficult to meet the requirements, and is prone to local deformation and overall tilting problems. For this reason, the construction team decided to use the large-area wall formwork support system proposed in the present invention for wall support.

[0086] According to the actual situation on site, the specific implementation plan 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 40×40×3mm square steel pipe. The base size is 3500mm×1800mm, with a column set at each of the four corners and the middle, for a total of 6 columns. The height of each column is 12.2 meters.

[0088] The adjustable support column adopts an outer cylinder-inner cylinder structure, with an outer cylinder diameter of 140mm and a thickness of 4mm; 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 through the adjustment mechanism.

[0089] The adjustment mechanism includes a vertically arranged screw, nut and handwheel. The screw has a diameter of 30 mm and a length of 1200 mm. 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 cooperates with the screw thread. By turning the handwheel, the screw can be driven to rotate, thereby driving the inner cylinder to slide up and down to achieve the adjustment of the support column height.

[0090] The locking device uses a locking bolt and a locking nut. The locking bolt passes horizontally through the side wall of the outer tube and can compress the inner tube; the locking nut is sleeved on the outer end of the locking bolt for locking and fixing. By tightening the locking nut, the inner tube can be locked in the adjusted position to prevent height changes.

[0091] According to the project requirements, the support system is equipped with 12 adjustable support columns, distributed in two rows and six columns. The effective adjustment range of each support column is 9.8-12.2 meters, which can meet the actual wall height requirements.

[0092] 2. Design of the template fixing device: The template fixing device includes a fixing seat, a pressure plate and a fastening bolt. The fixing seat adopts a U-shaped structure and is welded to the top of the inner tube. The U-shaped opening faces upward and is used to place the bottom edge of the wall template. The pressure plate adopts an L-shaped structure, with its horizontal part placed on the top surface of the wall template and the vertical part corresponding to the fixing seat. The fastening bolt passes through the vertical part of the pressure plate and the fixing seat to clamp and fix the wall template.

[0093] The dimensional parameters of the template fixing device are as follows: the width of the fixing seat is 400mm, the vertical height is 150mm, and the thickness is 10mm; 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] According to the thickness and stiffness characteristics of the wall formwork, through mechanical calculation and analysis, the maximum bearing capacity of the fixing device can reach 85kN, which is enough to support a concrete wall formwork that is 4 meters wide and 12 meters high.

[0095] 3. Design of transverse connecting beam: The transverse connecting beam adopts I-shaped steel structure, and the main beam size is 340mm×200mm×10mm. Triangular reinforcement ribs are set at the connection between the web and flange of the main beam to improve the bending rigidity of the beam. Connecting plates are set at both ends and fixed to the columns by welding.

[0096] There are multiple spaced apart arrangements along the length of the main beam. The adjustment holes are spaced 200 mm apart. These adjustment holes are used for fastening bolts to pass through and are used to adjust the installation position of the transverse connecting beam to improve adaptability.

[0097] According to calculations, in a 12-meter-high wall support, the maximum horizontal distance between each column should not exceed 3.6 meters. Therefore, this project uses 3.5-meter-span transverse connecting beams, with a total of 12 beams. By setting the adjustment holes, it can be flexibly installed according to the actual column spacing.

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

[0099] The locking sleeve is arranged at the connection between the outer tube and the inner tube, and the inner tube can be locked in the adjusted position by screwing in the M16 thread. A fixing ear plate is welded at the end of each of the outer tube and the inner tube for fixing and connecting 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 400mm. Through calculation, the effective length of the longitudinal reinforcement rod should be between 3800-4200mm. Therefore, during production, the length of the telescopic rod body is set to 4000mm, and the adjustment range is ±200mm, which can meet the needs of various support height differences.

[0101] 5. Design of anti-dumping assembly: The anti-dumping assembly includes diagonal braces, ground anchors and adjustment nuts. The upper end is connected to the top of the column by a hinge, and the lower end is connected to the adjusting nut by a thread. The threaded steel bar is buried in the ground, with its top exposed above the ground and equipped with The adjusting nut is hinged to the connecting hole of the ground anchor through a pin shaft.

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

[0103] To ensure the pull-out bearing capacity of the anchor, a threaded steel bar with a diameter of 30mm and a length of 800mm is used according to the soil conditions on site. The top of the anchor is 300mm above the ground and is hinged to the diagonal brace. By adjusting the rotation of the nut, the force state of the diagonal brace can be adjusted to enhance the stability of the entire support system.

[0104] 6. Design of the base and leveling device: The base adopts a welded rectangular frame structure, made of 50×50×5mm angle steel. A vertical downward support leg is provided at each of the four corners and the middle of the bottom of the frame, and a The leveling plate is connected to the support leg through M24 thread and can be rotated to adjust the level of the support system.

[0105] According to the engineering specifications, the base size is designed to be 3500mm×1800mm×150mm. By adjusting the leveling plate on the support foot, the ground height difference of ±50mm can be compensated to ensure the stability of the entire support system.

[0106] 7. Design of transverse reinforcement: In order to further enhance the overall rigidity of the support system, a transverse reinforcement is set in the middle between two adjacent adjustable support columns. The reinforcement includes a fixing sleeve, a connecting rod and a fastening bolt.

[0107] Fixed sleeve adopts Made of round tube, it can be placed on the outside of the adjustable support column and slide up and down. The round steel is hinged to two fixing sleeves at both ends. The fastening bolt is an M16 bolt, which can be locked at the specified position on the adjustable support column through the fixing sleeve.

[0108] By adjusting the position of the fixing sleeve and locking it, the length of the connecting rod can be changed to meet the requirements of different support column spacings. The design of the reinforcement can effectively enhance the overall rigidity and stability of the entire support system.

[0109] 8. On-site installation and commissioning: According to the above design plan, the specific installation steps of the large-area wall formwork support system of this project are as follows:

[0110] (1) First, level the ground at the construction site to ensure that the foundation is flat and has no depressions. Then place the base frame and adjust the leveling plates on the support feet to achieve horizontal correction of the base.

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

[0112] (3) Install the transverse connecting beam. First, weld the connecting plate to the column, and then fix the beam body and the connecting plate by tightening the bolts. According to the actual column spacing, adjust the beam body position appropriately and lock it.

[0113] (4) Install longitudinal reinforcement rods between adjacent support columns. First, weld the fixing ear plates to the support columns, then adjust the length of the telescopic rod body and secure it with a locking sleeve.

[0114] (5) Install the anti-dumping assembly. First, bury the anchor in the ground, and then connect the lower end of the diagonal brace to the anchor through the adjusting nut. The upper end is connected to the top of the column through a hinge. Adjust the inclination angle of the diagonal brace by rotating the adjusting nut.

[0115] (6) Finally, install the template fixing device. First, weld the fixing seat to the top of the inner tube, then place the bottom edge of the wall template in the fixing seat, and then clamp it with a pressure plate and fastening bolts.

[0116] During the entire installation process, operations must be strictly carried out in accordance with the design parameters and necessary safety precautions must be taken. For example, during the height adjustment of the support column, two workers should work together to complete the task, one to operate the hand wheel and the other to monitor the displacement of the support column. When fixing the formwork, it should also be temporarily fixed before the final tightening to ensure safety.

[0117] After the installation is completed, the construction team also needs to debug and inspect 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. Secondly, check whether each connection part is firm and reliable, and whether the fastening bolts are tightened in place. Thirdly, observe the overall deformation of the support system under the action of deadweight to ensure that the deformation is within the allowable range. Finally, under the action of simulated load, check the overall stability of the support system to ensure safety and reliability.

[0118] Only after careful installation and debugging can we ensure that this support system can play its due performance in actual construction. Construction personnel must strictly follow the design requirements and do a good job of various inspections to prevent any safety hazards.

[0119] 9. Performance verification and analysis: In order to verify the actual performance of the designed large-area wall formwork support system, the construction team built 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 aspects of performance indicators, as follows:

[0120] (1) Support strength and stability: Vertical and horizontal loads were applied to the support system using simulated loads. Test results showed that at a height of 12 meters, the support system could withstand a vertical load of 108 kN and a horizontal load of 32 kN, which was much higher than the maximum load required in actual wall construction. At the same time, under the load, the overall deformation of the support system was very small, and there was no overload of local support points or overall tilt, which demonstrated good overall stability.

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

[0122] (3) Installation convenience: Compared with traditional support systems, this support system is more convenient in installation and disassembly. The design of quick adjustment of support column height, flexible adjustment of beam position, and change of telescopic rod length greatly simplifies the complexity of on-site installation. In addition, the leveling of the base and automatic calibration of anti-dumping components further improve the installation efficiency.

[0123] (4) Safety in use: In the test under simulated strong wind conditions, the support system did not tilt or collapse, and the anti-dumping components 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 avoiding slippage under external forces. In addition, the design of the locking device can effectively prevent the support height from changing unexpectedly during use, thereby maximizing the safety of construction workers.

[0124] In general, through field tests and verification, the designed large-area wall formwork support system has met or exceeded the expected design requirements in various performance indicators, and can adapt well to complex construction environments and needs. Compared with traditional support systems, this system has been significantly improved in support strength, adjustability, safety, etc., providing a strong technical guarantee for high-quality concrete wall construction.

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

[0126]

[0127]

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

[0129] Specifically, the principles of the present invention are: 1. Support structure design with multiple adjustable support columns. The system uses multiple adjustable support columns as the main support components, and realizes the adjustability of the support height by setting an inner and outer cylinder structure that can slide up and down between the base and the column. This support method can not only effectively disperse the force and improve the overall bearing capacity, but also flexibly adjust the support height according to the on-site construction requirements to adapt to complex engineering environments. Compared with the traditional single column support, this multi-point support structural design has obvious advantages in bearing capacity, stability and adaptability.

[0130] 2. Coordinated design of the adjustment mechanism and the locking device. A special adjustment mechanism is set on the adjustable support column, including a screw-nut structure driven by a handwheel, which can adjust the height of the support column conveniently and quickly. At the same time, a locking device is also provided on the adjustment mechanism, and the adjusted support height position can be reliably fixed through the cooperation of the locking bolt and the locking nut. This coordinated design of the adjustment 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 adjustment mechanism can ensure that the support height does not change, avoiding safety hazards.

[0131] 3. Load-bearing design of the formwork fixture. A special formwork fixture is set at the top of the adjustable support column, including a fixing seat, a pressure plate and a fastening bolt. This fixing method can firmly clamp the wall formwork on the support system to ensure the accuracy and stability of the formwork position. Compared with simple placement or buckle fixing, this fixture can withstand greater external forces without displacement, thereby better ensuring the quality of the wall structure. At the same time, the load-bearing capacity of the formwork fixture is closely related to the stability of the adjustable support column. There is a certain mechanical relationship between the two, which can be optimized through calculation and analysis.

[0132] 4. Stable design of the anti-dumping assembly. In order to enhance the overall stability of the support system, the present invention sets an anti-dumping assembly on the outside of the column, including a diagonal brace, a ground anchor and an adjustment nut. This design can effectively resist external forces such as wind and rain, and reduce the risk of the entire support system overturning. 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. Reasonable dimensional parameters can be determined through calculation and analysis to ensure that the anti-dumping assembly can provide sufficient supporting force. At the same time, the design of the adjusting nut can also achieve fine-tuning of the angle of the diagonal brace, further improving the stability of the support system.

[0133] 5. Optimized design of transverse connecting beams and longitudinal reinforcement rods. The transverse connecting beam adopts an I-shaped steel structure, which can improve the transverse stiffness and bearing capacity; adjustment holes are set on the beam body, and its installation position can be adjusted according to actual conditions to improve adaptability. The longitudinal reinforcement rod adopts a telescopic rod structure, and the length can be quickly changed by adjusting the locking sleeve to meet the needs of different support height differences. These optimized designs not only enhance the overall stability of the system, but also improve its versatility and flexibility.

[0134] The key technical designs in the above aspects together constitute the core principle of the large-area wall formwork support system proposed by the present invention. Among them, multiple adjustable support columns as the main bearing components improve the overall support strength and stability; the coordinated design of the adjustment 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-dumping component enhances the ability of the support system to resist external forces; the optimized design of the transverse connecting beam and the longitudinal reinforcement rod further improves the versatility and adaptability of the system.

[0135] These technical innovations fully reflect the effective solutions proposed by the present invention for the problems existing in the existing large-area wall formwork support system. The support system has not only made significant progress in terms of load-bearing capacity, adjustability, stability, safety, etc., but also has great advantages in terms of construction efficiency and worker safety. This comprehensive performance improvement enables the large-area wall formwork support system of the present invention to better adapt to the increasingly complex and diverse needs of current construction projects, and provide strong technical support for high-quality construction.
