Description

Technical Field

[0001] This utility model relates to the field of scaffolding, and in particular to a platform system for the construction of cast-in-place concrete structures. Background Technology

[0002] For formwork supports of cast-in-place frame concrete structures, existing methods typically use frame structure cup-coupler scaffolding and disc-coupler scaffolding, which form the scaffolding by connecting the uprights and horizontal bars with cup-couplers or disc-couplers.

[0003] However, the existing scaffolding system has the following problems; (1) Each section of the flow requires complete installation and dismantling, which is repetitive and labor-intensive; (2) The space formed by the frame is small, making it difficult for personnel to pass through, which is not conducive to the personnel monitoring of the safety of the formwork during the concrete pouring process; (3) Existing scaffolding transportation requires loading each scaffold one by one onto a vehicle, which takes a long time and requires a lot of manpower.

[0004] Therefore, how to solve the above problems has become an urgent issue for those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a scaffolding system for the construction of cast-in-place concrete structures. This patent combines and integrates the assembled gantry platform, lifting mechanism and scaffolding mechanism to achieve modularity and height adjustment of the overall structure. Compared with the scaffolding in the background technology that is repeatedly assembled and disassembled, this system can adjust the height as a whole and move it, which greatly reduces the labor and time costs of repeated installation and dismantling, and thus significantly improves construction efficiency and economy.

[0006] This utility model is achieved through the following technical solution: A gantry system for cast-in-place concrete structure construction includes an assembled gantry platform, a lifting mechanism, and a scaffolding mechanism. The scaffolding mechanism is arranged on the gantry platform, with its upper end abutting against the bottom formwork of the concrete structure. The lower end of the scaffolding mechanism is adjustablely and fixedly connected to the gantry platform. The lifting mechanism is arranged inside the gantry platform and drives the gantry platform and the scaffolding mechanism to adjust up and down synchronously.

[0007] This patent integrates and designs a modular gantry platform, a lifting mechanism, and a scaffolding mechanism, achieving modularity and adjustable height of the overall structure. Compared to the repetitive assembly and disassembly of scaffolding in the prior art, this system allows for overall height adjustment and relocation, significantly reducing the labor and time costs associated with repeated installation and dismantling. The gantry platform of this patent provides a larger passageway at the bottom, facilitating safety monitoring during the pouring process and effectively solving the problems of narrow space and difficult personnel passage in existing scaffolding systems. The modular design of this patent facilitates overall transportation and rapid on-site assembly, avoiding the inefficiency of loading individual components onto trucks. It can be quickly transferred to the next construction area via a movable lifting mechanism, thereby significantly improving construction efficiency and economy.

[0008] According to the above technical solution, preferably, the gantry platform includes, from bottom to top, multiple sets of adjustable column assemblies, horizontally arranged X-direction support members, Y-direction support members, and diagonal support rods. The X-direction support members and Y-direction support members are vertically fixedly connected. The two ends of the Y-direction support members are detachably fixedly connected to the upper ends of the adjustable column assemblies. The two ends of the X-direction support members are detachably fixedly connected to the Y-direction support members. The lower end of the scaffolding mechanism is adjustablely fixedly connected to the X-direction support members. The lifting end of the lifting mechanism is fixedly connected to multiple sets of the X-direction support members. The two ends of the diagonal support rods are respectively fixedly connected to the middle parts of the adjustable column assemblies and the X-direction support members.

[0009] As can be seen, the above technical solution forms a stable and adjustable support frame through the coordinated connection of multiple sets of adjustable column components with X-axis, Y-axis supports and diagonal support rods. This structure not only enhances the overall rigidity and stability of the gantry platform, but also enables rapid assembly and disassembly through detachable connections, reducing on-site operation time. Simultaneously, the adjustable connection between the scaffolding mechanism and the X-axis supports allows the scaffolding height to be adjusted synchronously with the gantry, further improving the system's adaptability and construction flexibility.

[0010] According to the above technical solution, preferably, the adjustable column assembly includes an upper column, a lower column, and an adjustable unit from top to bottom. The upper end of the upper column is detachably connected to the Y-axis support member. The upper end of the upper column is provided with a plug. The Y-axis support member is provided with a slot adapted to the plug. The plug and the slot are provided with screw holes adapted to the connecting bolts. The lower part of the upper column is fixedly connected to the upper part of the lower column by plugging. The adjustable unit is arranged at the lower end of the lower column.

[0011] As can be seen, the above technical solution achieves fast and reliable assembly and disassembly through the plug-in connection and bolt fixation between the upper column and the Y-direction support, reducing the time wastage caused by traditional welding or complex connections; the plug-in connection between the upper column and the lower column and the setting of the adjustable unit make the height of the adjustable column assembly adjustable, which can adapt to different ground heights and construction needs, improving the versatility and on-site adaptability of the system.

[0012] According to the above technical solution, preferably, the scaffolding mechanism includes a vertical support rod, a horizontal connecting rod, and an inclined connecting rod that are locked together by a disc buckle. The upper and lower ends of the vertical support rod are respectively adjustable and fixedly connected to the bottom formwork and the X-direction support member through adjustable units.

[0013] As can be seen, the above technical solution forms a stable and easy-to-assemble spatial frame by quickly locking the vertical support rods, horizontal connecting rods, and diagonal connecting rods. The disc-lock connection method has the advantages of convenient assembly and disassembly and high reliability, further reducing labor and operation time. At the same time, the vertical support rods are connected to the bottom formwork and gantry platform through adjustable units to achieve fine adjustment of the scaffolding height, ensuring the accuracy and safety of the formwork support during concrete pouring.

[0014] According to the above technical solution, preferably, the adjustable unit includes a threaded support base and a locking sleeve, the lower end of the support base abuts against the ground, the upper part of the support base is inserted into the lower column, and the locking sleeve abuts against the lower end face of the lower column.

[0015] As can be seen, the above technical solution achieves fine-tuning and fixing of the height of the lower column through the threaded connection of the support base and locking sleeve. The structure is simple, reliable, easy to operate, and can quickly adjust the verticality and overall levelness of the column.

[0016] According to the above technical solution, preferably, the lifting mechanism includes a movable base and multiple sets of synchronously moving scissor-type lifting components. The scissor-type lifting components are arranged on the movable base, and the upper end of the scissor-type lifting components is fixedly connected to the X-direction support of the gantry platform.

[0017] As can be seen, in the above technical solution, the smooth lifting and lowering of the gantry platform is achieved through multiple sets of synchronously moving scissor structures; the scissor lifting components have the advantages of large stroke, good stability and strong load-bearing capacity, which can effectively support the overall weight of the gantry platform and scaffolding mechanism; the movable base facilitates the overall transfer of the system, avoiding the cumbersome process of completely disassembling and transporting traditional scaffolding, and significantly improving construction turnover efficiency and mechanization level.

[0018] The beneficial effects of this utility model are: (1) This patent combines the assembled gantry platform, lifting mechanism and scaffolding mechanism into an integrated design to achieve modularity and adjustable height of the overall structure. Compared with the scaffolding that is repeatedly assembled and disassembled in the background technology, this system can adjust the height as a whole and move it, which greatly reduces the labor and time costs of repeated installation and dismantling. (2) The gantry platform of this patent provides a larger bottom passage space, which facilitates personnel to conduct safety monitoring during the pouring process and effectively solves the problem of narrow space and difficult passage of personnel in the existing frame structure; (3) The modular design of this patent facilitates overall transportation and rapid on-site assembly, avoiding the problem of low loading efficiency of single rods. It can be quickly transferred to the next construction area through a movable lifting mechanism, thereby significantly improving construction efficiency and economy. Attached Figure Description

The lifting mechanism 2 is arranged inside the gantry platform 1, and the lifting mechanism 2 drives the gantry platform 1 and the scaffolding mechanism 3 to adjust up and down synchronously. The gantry platform 1, from bottom to top, includes multiple adjustable column assemblies 4, horizontally arranged X-axis support members 5, Y-axis support members 6, and diagonal support rods 7.

Through the coordinated connection of multiple sets of adjustable column assemblies 4 with the X-direction support 6, Y-direction support 6 and diagonal support rods 7, a stable and adjustable support frame is formed. This structure not only enhances the overall rigidity and stability of the gantry platform 1, but also enables rapid assembly and disassembly through a detachable connection, reducing on-site operation time.

[0023] This patent integrates and designs the assembled gantry platform 1, the lifting mechanism 2, and the scaffolding mechanism 3, achieving modularity and adjustable height of the overall structure. Compared to the scaffolding in the prior art that requires repeated assembly and disassembly, this system can adjust the height as a whole and move it, significantly reducing the labor and time costs associated with repeated installation and dismantling. The gantry platform 1 of this patent provides a larger passage space at the bottom, facilitating safety monitoring by personnel during the pouring process and effectively solving the problems of narrow space and difficult personnel passage in existing scaffolding. The modular design of this patent facilitates overall transportation and rapid on-site assembly, avoiding the problem of low efficiency in loading individual components.

Through the quick locking of the vertical support rod 13, the horizontal connecting rod 14, and the inclined connecting rod 15, a stable and easy-to-assemble spatial frame is formed. The disc buckle connection method has the advantages of convenient assembly and disassembly and high reliability, further reducing labor and operation time. At the same time, the vertical support rod 13 is connected to the bottom formwork 20 and the gantry platform 1 through the adjustable unit 10, realizing the fine adjustment of the scaffolding height and ensuring the accuracy and safety of the formwork support during the concrete pouring process.

Through the threaded support base 16 and locking sleeve 17, the height of the lower column 9 can be finely adjusted and fixed. This structure is simple and reliable, easy to operate, and can quickly adjust the verticality and overall levelness of the column.

The scissor-lifting components 19 are arranged on the movable base 18, and the upper end of the scissor-lifting components 19 is fixedly connected to the X-direction support 5 of the gantry platform 1. The gantry platform 1 is raised and lowered smoothly through multiple sets of synchronously moving scissor structures.
