Description

Technical Field

[0001] This utility model relates to the field of construction technology for municipal engineering rainwater drainage projects, specifically to a large-scale rainwater drainage box culvert steel formwork structure. Background Technology

[0002] With the continuous expansion of urban construction, the increasing area of ​​hardened concrete has led to a gradual increase in the frequency of urban flooding. To alleviate this problem, constructing more urban box culvert drainage systems has become an important measure. However, traditional construction methods for cast-in-place box culvert formwork systems face many challenges, affecting construction efficiency and cost control.

[0003] First, the formwork system for cast-in-place box culverts requires a large amount of materials, and traditional construction techniques result in a slow turnover rate of formwork materials. Under the assembly line operation mode, the construction team needs a large amount of turnover materials. As the amount of materials transported increases, idle work is likely to occur on the construction site, resulting in low construction efficiency and thus increasing construction costs.

[0004] Secondly, existing formwork support systems pose significant safety hazards. The erection of support poles lacks standardization and is highly arbitrary, resulting in poor construction safety and difficulty in effectively controlling risks during construction. Furthermore, the formwork assembly process is mostly handled by workers themselves, lacking standardized management. This not only hinders material conservation but also fails to meet energy conservation and environmental protection requirements.

[0005] Finally, traditional formwork support systems have drawbacks in terms of dismantling. Ordinary formwork support systems cannot be dismantled quickly and require a large number of formwork and supporting main and secondary beams, which leads to a significant consumption of materials and labor, seriously affecting the construction period, increasing project costs, and making the construction process cumbersome and inconvenient.

[0006] In summary, the existing cast-in-place box culvert formwork support system has many shortcomings in terms of material utilization, construction safety, environmental protection requirements, and efficiency. It is urgent to improve construction efficiency, reduce costs, and ensure construction safety through technological innovation and process improvement. Utility Model Content

[0009] Furthermore, the edge ribs of the inner plate and the top plate are provided with multiple mounting holes and are connected by pins.

[0010] Furthermore, each support component includes a sleeve and a telescopic tube. The bottom end of the sleeve abuts against the reinforced concrete foundation, and the top end is fitted with the telescopic tube. The telescopic tube is threadedly connected to the sleeve and its connection position with the sleeve can be adjusted, thereby flexibly controlling the height of the support component.

[0011] Furthermore, the top end of the telescopic tube is provided with a connecting hole and is connected to the stiffening ribs of the inner plate or the top plate through a connector.

[0012] Furthermore, the bottom end of the support assembly connected to the inner plate abuts against the pre-embedded steel bars on the reinforced concrete foundation.

[0013] Furthermore, a right-angle back rib is provided at the corner between the inner plate and the top plate.

[0014] Furthermore, the outer panel, inner panel, and top panel are all composed of multiple steel templates assembled together.

[0015] Furthermore, each steel template has multiple mounting holes on its edge ribs, and two corresponding mounting holes on two adjacent steel templates are penetrated by pins. Each pin has a pin hole, and a pin plate is inserted into the pin hole.

[0016] Furthermore, the cross-section of the pin plate gradually decreases from the insertion end to the end.

[0017] Furthermore, the connecting member is a pull screw.

However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0023] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of protection of this invention.

[0024] Reference Figures 1 to 4 This embodiment provides a large-scale stormwater drainage culvert steel formwork structure, including an outer plate 1, an inner plate 2, and a top plate 3. The outer plate 1 is vertically laid on the outer side of a reinforced concrete foundation 100, and the inner plate 2 is vertically laid on the inner side of the reinforced concrete foundation 100. The outer plate 1 and inner plate 2 on the same side of the reinforced concrete foundation 100 are spaced apart and detachably connected by connectors 4. The top plate 3 is connected to the top of the two inner plates 2 located inside the reinforced concrete foundation 100. The reinforced concrete foundation 100 is provided with multiple support components 5, the bottom end of each support component 5 abuts against the reinforced concrete foundation 100, and the top end is supported and connected to the inner plate 2 or the top plate 3. By combining the outer plate 1, inner plate 2, and top plate 3, the design of the formwork support system is optimized, solving the problems of low construction efficiency and material waste in traditional formwork support systems. The detachable connection between the outer plate 1 and inner plate 2 via connectors 4 can improve the turnover speed of the formwork and support system, save material usage, and reduce construction costs. The top plate 3 is connected to the top of the inner plate 2. Simultaneously, the design of the support components 5 ensures that the bottom of each support component 5 abuts against the reinforced concrete foundation 100, while the top is connected to either the inner plate 2 or the top plate 3, enhancing the system's stability and rigidity and ensuring accurate cross-sectional dimensions during component casting. This structure features easy disassembly and high construction safety, effectively improving construction efficiency and allowing for multiple reuses of the formwork and support system, thereby further reducing material and labor costs.

[0025] In this embodiment, the edge ribs of the inner plate 2 and the top plate 3 are provided with multiple mounting holes 22 and are connected by pins 6. The pin connection method simplifies the operation steps and makes the disassembly process faster and more convenient. This design not only improves the construction progress but also reduces the intensity of manual operation, which helps to improve construction safety and overall efficiency, and conforms to the technical characteristics of rapid disassembly and efficient material utilization in this embodiment.

[0026] In this embodiment, each support component 5 includes a sleeve 51 and a telescopic tube 52. The bottom end of the sleeve 51 abuts against the reinforced concrete foundation 100, and the top end is fitted with the telescopic tube 52. The telescopic tube 52 is threadedly connected to the sleeve 51 and its connection position with the sleeve 51 can be adjusted, thereby flexibly controlling the height of the support component 5. The top end of the telescopic tube 52 is provided with a connecting hole and is connected to the stiffening ribs of the inner plate 2 or the top plate 3 through a connector. This design not only improves the flexibility of construction but also adapts to the construction needs of box culverts of different sizes, while simplifying the adjustment process of the support component 5 and improving construction efficiency and safety.

[0027] In this embodiment, the bottom end of the support component 5, which is connected to the inner plate 2, abuts against the pre-embedded steel bars 101 on the reinforced concrete foundation 100, further enhancing the stability and load-bearing capacity of the support component. Through the close cooperation with the pre-embedded steel bars 101, the support component 5 can be effectively fixed to the foundation, avoiding support displacement or instability caused by vibration or other factors during concrete pouring. This design improves the safety of the formwork system, ensuring that the formwork and support system are always in optimal stress state during concrete pouring, thus contributing to improved construction quality and efficiency.

[0028] In this embodiment, a right-angled back rib 7 is provided at the corner between the inner plate 2 and the top plate 3, further enhancing the stability and rigidity of the formwork structure. The right-angled back rib 7 effectively supports the connection between the inner plate 2 and the top plate 3, preventing deformation or displacement at the corner, thereby ensuring that the formwork system maintains accurate shape and dimensions during concrete pouring. This design not only improves the strength of the structure but also improves the stress distribution of the formwork, enhancing the safety and precision of construction.

[0029] In this embodiment, the outer plate 1, inner plate 2, and top plate 3 are all composed of multiple steel formwork panels 21, making the formwork structure more flexible and easier to adjust. By assembling multiple steel formwork panels 21, the size of the formwork can be flexibly combined and adjusted according to different construction needs to adapt to the construction of box culverts of different specifications and shapes. This design not only improves the adaptability of the formwork but also facilitates transportation and storage, while reducing material waste. The modular structure makes the installation and disassembly of the formwork more convenient, improves construction efficiency, and facilitates the reuse of the formwork, further saving construction costs.

[0030] In this embodiment, each steel template 21 has multiple mounting holes 22 on its edge ribs. Two corresponding mounting holes 22 on adjacent steel templates 21 are pierced by pins 6. Each pin 6 has a pin hole 61, into which a pin plate 62 is inserted. This design improves the stability and reliability of the template splicing. Through pin connection, adjacent steel templates 21 can be tightly joined, effectively preventing template displacement or deformation during construction. Simultaneously, the pin connection method is simple and easy to operate, allowing construction personnel to quickly complete template installation and disassembly, improving construction efficiency. This design also facilitates standardized and modular template production, further reducing the complexity of on-site construction and material waste.

[0031] In this embodiment, the cross-section of the pin plate 62 gradually decreases from the insertion end to the end, forming a trapezoid. When the pin is inserted into the pin hole 61, it pulls the two adjacent steel templates 21 closer together and squeezes them to achieve a squeezing and fixing effect, preventing gaps between the steel templates 21 and preventing the pin 6 from falling off.

[0032] In this embodiment, the connecting member 4 is a tie rod, providing a more stable and reliable connection method. The tie rod is tightened by nuts on both sides, effectively fixing the outer plate 1 and the inner plate 2 together, ensuring that the formwork will not shift or loosen during construction. The application of the tie rod makes the formwork connection more evenly stressed, improving the overall rigidity and stability of the formwork system. Furthermore, the tie rod is easy to disassemble, allowing construction personnel to quickly complete the formwork removal work, further improving construction efficiency. This design is simple, economical, and highly adaptable, meeting the construction requirements of box culverts of different specifications.

[0033] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these are within the scope of protection of the present invention.
