Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a formwork system that can be rolled up to adapt to curved concrete structures. Background Technology

[0002] Cast-in-place concrete structures involve pouring concrete into formwork and shaping it. Existing formwork technologies include wooden formwork and metal formwork, whose materials and dimensions can be flexibly selected according to actual construction needs. However, most existing formwork technologies are flat formwork or customized curved formwork, which cannot adapt to different curved concrete structures, such as formwork for irregularly shaped building exterior walls (e.g., wavy, spiral), arched tunnel lining formwork, curved bridge crash barrier formwork, landscape pools, curved fountain formwork, and curved precast component forming (e.g., curved beams, columns), etc.

[0003] Furthermore, while customized curved formwork can adapt to curved concrete structures of corresponding shapes, it suffers from problems such as difficulty in supporting irregularly shaped structures, inconvenient demolding, high cost, inability to be reused, high requirements for processing precision, and inconvenience in transportation. Therefore, there is a need to provide a formwork system that can be rolled up to adapt to curved concrete structures, which can solve the problems of existing formwork technology being unable to adapt to irregularly shaped curved concrete structures and inconvenient transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a formwork system that can be rolled up to adapt to curved concrete structures, which can solve the problems of existing formwork systems being unable to adapt to irregular curved concrete structures and being inconvenient to transport.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A formwork system adaptable to curved concrete structures includes fixed formwork units and movable adjustment units. The fixed formwork unit comprises a flat frame module, connecting support rods, hinged nodes, and a first connecting rod. One end of each connecting support rod is fixedly connected to the end of the flat frame module. A pair of connecting support rods are symmetrically arranged at both ends of the flat frame module. The other ends of the pair of connecting support rods are movably hinged to both ends of the first connecting rod via hinged nodes. The movable adjustment unit comprises a hydraulic drive control component, hinged nodes, and second connecting rods. The fixed end of the hydraulic drive control component is mounted on the flat frame module. The telescopic end of the hydraulic drive control component is movably hinged to one end of a pair of second connecting rods via hinged nodes. The other ends of the pair of second connecting rods are movably hinged to the ends of the first connecting rods of two adjacent sets of fixed formwork units via hinged nodes. The two adjacent sets of fixed formwork units are movably connected via rotating components. Several sets of fixed formwork units and several sets of movable adjustment units are sequentially and alternately connected to form a rollable formwork system.

[0007] The back of the flat plate frame module is provided with a reinforcing back rib, and a number of reserved holes are formed at intervals on the reinforcing back rib. The reinforcing back rib is connected and fixed to the flat plate frame module through the reserved holes. A number of ear plates are provided at intervals on the rear web plate of the reinforcing back rib. The support system is connected to the reinforcing back rib through the ear plates and is supported between the back of the flat plate frame module and the support surface.

[0008] The flat frame module and the first connecting rod are connected by several steel wire ropes at intervals.

[0009] In each set of fixed template units, the flat frame module, a pair of connecting support rods and the first connecting rod form an isosceles trapezoidal structure, forming a stable structural system.

[0010] When the telescopic end of the hydraulic drive control component is extended to its longest state, the two adjacent connecting support rods in the two adjacent sets of fixed template units and a pair of second connecting rods form a quadrilateral structure that is symmetrical about the hydraulic drive control component. The lengths of the two sides of this symmetrical quadrilateral structure are the same as the lengths of the legs of the isosceles trapezoidal structure, which is the length of the connecting support rod.

[0011] When the telescopic end of the hydraulic drive control component is extended to its longest state, a pair of first connecting rods in several sets of movable adjustment units are in a V-shaped structure, so that the entire rollable template system is in an O-shaped closed state.

[0012] When the telescopic end of the hydraulically driven control component extends, a pair of first connecting rods in several sets of movable adjustment units are in a V-shaped structure, so that the entire rollable template system is in a C-shaped rolled state, that is, a semi-unrolled state.

[0013] When the telescopic end of the hydraulic drive control component is retracted to its shortest state, two adjacent connecting support rods in two adjacent sets of fixed template units and a pair of second connecting rods form an isosceles triangle structure. The length of the leg of the isosceles triangle structure is the same as the length of the leg of the isosceles trapezoid structure, which is the length of the connecting support rod.

[0014] When the telescopic end of the hydraulic drive control component is retracted to its shortest state, the flat frame modules of several sets of fixed template units are located in the same plane, and the first connecting rods of several sets of movable adjustment units are located on the same straight line and are parallel to the flat frame modules, so that the entire rollable template system is in a flattened state.

[0015] The rollable template system is provided with anchoring devices at both ends, and the two ends of the rollable template system are fixed by the anchoring devices.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention features a fixed template unit and a movable adjustment unit. The hydraulic drive control of the movable adjustment unit controls the rotation of a pair of second connecting rods, causing the movable adjustment unit to deform. This allows for one-click automatic switching of the rollable template system between flattened, closed, and rolled states, eliminating the need for traditional, cumbersome assembly work and extensive scaffolding erection. This significantly improves construction efficiency, reduces costs, and saves resources. Especially during the demolding stage, utilizing the reverse rolling principle, the template formed by the flat frame module can automatically retract inward and detach from the concrete surface, avoiding damage to the concrete edges caused by traditional pry bar demolding, and greatly improving construction safety and efficiency.

[0018] 2. This invention, with its movable adjustment unit, allows for continuous curvature variation and stepless adjustment, giving the fixed template unit excellent surface adaptability and enabling it to fit irregularly shaped concrete structures. Compared to traditional templates that can only preset a few fixed arc radii, the hydraulic drive control component of this invention, in conjunction with the rotating node, can achieve continuous stepless changes from flat surfaces to arcs with arbitrarily large curvatures, demonstrating strong surface adaptability. Simultaneously, the stroke of the hydraulic drive control component can be precisely controlled to the millimeter level, ensuring high controllability of construction accuracy and minimizing the geometric error between the template surface and the design model. This makes it particularly suitable for fair-faced concrete or irregularly shaped concrete structures requiring extremely high surface flatness.

[0019] 3. Because the invention uses hinged nodes and rotating parts, it gives the rollable formwork system a certain degree of flexibility. During the concrete pouring process, if there is uneven local pressure, the hinged nodes can rotate slightly to release stress, which can effectively prevent the traditional rigid formwork from bursting or warping due to the inability to release stress.

[0020] 4. This invention achieves highly intensive storage after construction, significantly reducing warehousing and transportation costs. Each unit and module can be reused, meeting the requirements of green construction. It can solve the problems of traditional rigid templates being unable to adapt to complex curved surfaces, having low precision and flatness, and being difficult to turnaround and transport. It can be applied to irregular building exterior wall templates (such as wave-shaped and spiral-shaped), arched tunnel lining templates, bridge curved anti-collision guardrail templates, landscape pools, fountain curved templates, and precast component curved surface forming (such as curved beams and columns).

Detailed Implementation

[0031] The formwork system for adaptable curved concrete structures proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.

[0032] Please see the appendix Figure 1 To be continued Figure 4 Appendix Figure 6 and attached Figure 7A formwork system adaptable to curved concrete structures is disclosed, comprising fixed formwork units and movable adjustment units. The fixed formwork unit includes a flat frame module 1, connecting support rods 3, hinge nodes 5, and a first connecting rod 10. One end of the connecting support rod 3 is fixedly connected to the end of the flat frame module 1. A pair of connecting support rods 3 are symmetrically arranged at both ends of the flat frame module 1, and the other ends of the pair of connecting support rods 3 are movably hinged to both ends of the first connecting rod 10 via hinge nodes 5. The movable adjustment unit includes a hydraulic drive control component 2, hinge nodes 5, and a second connecting rod 11. The fixed end of the hydraulic drive control component 2 is mounted on the flat frame module 1, and the telescopic end of the hydraulic drive control component 2 is movably hinged to one end of a pair of second connecting rods 11 via hinge nodes 5. The other ends of the pair of second connecting rods 11 are movably hinged to the ends of the first connecting rods 10 of two adjacent fixed formwork units via hinge nodes 5. Two adjacent fixed formwork units are movably connected via rotating components 9. Several sets of fixed formwork units and several sets of movable adjustment units are sequentially and alternately connected to form a rollable formwork system.

[0033] The number of fixed template units and movable adjustment units can be adjusted according to actual usage needs. Relying on the coordinated operation of the flat frame module 1, hydraulic drive control component 2, connecting support rod 3, hinge node 5 and rotating component 9, the form switching and working condition adaptation are completed in three stages at the opening direction 4.

[0034] The fixed template unit and the movable adjustment unit are connected by a hinge node 5 and a rotating part 9, which ensures the degree of freedom of rotation and prevents them from separating.

[0035] Please see the appendix Figure 6 The specifications of the rotating component 9 correspond to the module of the flat frame module 1, and its length can be adjusted to adapt to structural dimensions. The rotating component 9 has standardized interfaces at both ends for easy connection with the hydraulic drive control component 2, and also supports quick assembly and disassembly.

[0036] Based on the dimensions of the flat panel frame module 1, multiple sets of fixed template units and movable adjustment units can be installed on each flat panel frame module 1 to form a truss structure, thereby improving the structural strength of the rollable template system. The flat panel frame module 1 can be made of lightweight, high-strength materials, such as aluminum alloy, glass fiber reinforced plastic, or wood-plastic composite materials, to form a molded modular assembly that meets the module requirements.

[0037] Preferably, the hinge node 5 can be formed by connecting existing hinge components, and the rotating component 9 can be a rotatable component such as a rotating shaft or pin. The hydraulic drive control component 2 can be a miniature hydraulic push-pull rod with an automatic locking function, powered by a small lithium battery pack. The hydraulic rod is connected to the central control system through a solenoid valve, supporting precise control via wireless remote control or automatic program. It can automatically lock after its extension end reaches the required length, ensuring the current state of the rollable template system and ensuring construction safety.

[0038] Preferably, the rollable formwork system can be equipped with existing overload protection and emergency stop devices according to actual usage needs to ensure construction safety.

[0039] Please see the appendix Figure 5 The back of the flat frame module 1 is provided with a reinforcing back rib 12, and a number of reserved holes 6 are formed on the reinforcing back rib 12 at intervals. The reinforcing back rib 12 is connected and fixed to the flat frame module 1 through the reserved holes 6 by means of pins and pins.

[0040] Preferably, the reinforcing back rib 12 can adopt a structure in which the main and secondary ribs intersect. The number and spacing of the main and secondary ribs of the reinforcing back rib 12 can be adaptively adjusted according to the rigidity requirements of the flat frame module 1 to ensure that the flat frame module 1 will not be deformed or damaged during the concrete pouring process.

[0041] The reserved hole 6 and the pin and pin piece form a standardized interface, supporting quick assembly and disassembly.

[0042] Please see the appendix Figure 5 The back plate of the reinforcing back rib 12 is provided with several ear plates 7 at intervals. The support system (not shown in the figure) is connected to the reinforcing back rib 12 through several ear plates 7 and is supported between the back of the flat frame module 1 and the support surface (such as the ground, floor slab, etc.).

[0043] The support system can be used to prepare for load-bearing during subsequent concrete pouring, forming a stable formwork system with the rollable formwork system capable of bearing the load of concrete pouring. The support system can use steel cables, reinforced support rods, etc., to ensure safety and stability in a fixed state (fixed during use or locked during transportation).

[0044] Please see the appendix Figure 8 The flat frame module 1 and the first connecting rod 10 are connected by several steel wire ropes 8 at intervals, which are used to meet the tensile strength of the entire rollable template system in the C-shaped curled state.

[0045] Please see the appendix Figure 1 To be continued Figure 3In each set of fixed template units, the flat frame module 1, a pair of connecting support rods 3 and the first connecting rod 10 form an isosceles trapezoidal structure (approximately an isosceles triangle structure), forming a stable structural system.

[0046] The pair of connecting support rods 3 and the first connecting rod 10 can be made of the same rigid material as the flat frame module 1 to form a whole, ensuring its stability. A pin hole is provided at the top to facilitate the formation of a hinged joint with a pair of second connecting rods 11. A standardized interface is used, which also supports quick assembly and disassembly.

[0047] Please see the appendix Figure 3 When the telescopic end of the hydraulic drive control component 2 is extended to its longest state, the two adjacent connecting support rods 3 in the two adjacent sets of fixed template units and a pair of second connecting rods 11 form a quadrilateral structure that is symmetrical about the hydraulic drive control component 2, and the lengths of the two sides of the symmetrical quadrilateral structure are the same as the lengths of the legs of the isosceles trapezoidal structure, which is the length of the connecting support rod 3.

[0048] Please see the appendix Figure 3 When the telescopic end of the hydraulic drive control component 2 is extended to its longest state, a pair of first connecting rods 10 in several sets of movable adjustment units are in a V-shaped structure, so that the entire rollable template system is in an O-shaped closed state.

[0049] In this O-shaped closed state, each flat frame module 1 is connected to the hydraulic drive control component 2 in its longest state via the rotating component 9 and the connecting support rod 3, forming a compact polygonal structure at the hinge node 5 and both ends of the rotating component 9. At this time, the overall shape is regular, which can not only meet the overall transportation and storage needs and reduce logistics costs, but also allow for further disassembly of each component according to the actual site conditions, flexibly adapting to the needs of different structural sections and realizing the efficient reuse of components.

[0050] Please see the appendix Figure 2 When the telescopic end of the hydraulic drive control component 2 extends (between the shortest and longest lengths), a pair of first connecting rods 10 in several sets of movable adjustment units are V-shaped, so that the entire rollable template system is in a C-shaped roll-up state, i.e., a semi-unrolled state.

[0051] As the retraction end of the hydraulic drive control component 2 retracts, the entire rollable template system gradually unfolds along the preset opening direction 4. The retraction of the hydraulic drive control component 2 pulls the connecting support rod 3 to rotate around the hinge node 5, and the flat frame module 1 unfolds outward in sync, entering a C-shaped roll-up state, i.e., a semi-unrolled state.

[0052] At this point, the degree of unfolding of the C-shaped curl can be locked according to the changes in the cross-sectional curvature, so that it perfectly matches the design shape of the curved concrete structure, and also facilitates overall transportation and storage.

[0053] Please see the appendix Figure 1 When the telescopic end of the hydraulic drive control component 2 is retracted to its shortest state, the two adjacent connecting support rods 3 in the two adjacent fixed template units form an isosceles triangle structure with a pair of second connecting rods 11. The length of the leg of the isosceles triangle structure is the same as the length of the leg of the isosceles trapezoid structure, which is the length of the connecting support rod 3.

[0054] Please see the appendix Figure 1 When the telescopic end of the hydraulic drive control component 2 is retracted to its shortest state, the flat frame modules 1 of several sets of fixed template units are located in the same plane, and the first connecting rods 10 in several sets of movable adjustment units are located on the same straight line, and the first connecting rods 10 are parallel to the flat frame modules 1, so that the entire rollable template system is in a flattened state (or a large curvature surface state).

[0055] In the flattened state, the flat frame modules 1 of several fixed template units are located in the same plane, and the first connecting rods 10 of several movable adjustment units are located on the same straight line and parallel to the plane where the flat frame modules 1 are located. The hydraulic drive control component 2 retracts to its shortest limit, and together with the connecting support rods 3, forms a mechanically self-locking geometric configuration. Even if the hydraulic power is removed, the structure of the entire rollable template system can still maintain a rigid shape by relying on the stability of isosceles triangles and isosceles trapezoids. At this time, the anchoring devices at both ends of the safety system should be locked to prevent displacement.

[0056] The rollable formwork system is equipped with anchoring devices (not shown in the figure) at both ends. The two ends of the rollable formwork system are fixed by the anchoring devices to ensure the system is fixed in a stable state and to prevent displacement during construction.

[0057] Please see the appendix Figure 1 To be continued Figure 8 The working process and working principle of this invention are as follows:

[0058] The roll-up mechanism of the rollable template system is adjusted via a hydraulically driven control component 2. When the hydraulically driven control component 2 extends, equivalent to the transformation of an isosceles triangle into a quadrilateral structure, a pair of second connecting rods 11 fold accordingly, causing the entire rollable template system to "roll up" towards the center; conversely, it unfolds. During the roll-up process, all nodes maintain synchronous linkage to ensure structural stability and prevent jamming.

[0059] This invention utilizes the hydraulic drive control component 2 to adjust the formwork and automate the demolding process, forming a complete closed-loop control logic with the aforementioned unfolding and concrete pouring stages. When the concrete reaches its design strength and demolding is required, the entire rollable formwork system switches from "locked mode" to "rollable mode." At this time, the hydraulic drive control component 2, controlled by the central hydraulic control unit, precisely retracts again along the preset opening direction 4 (i.e., the opposite direction to the unfolding direction). This action breaks the original mechanical self-locking geometry, forcing each flat frame module 1 to rotate slightly around the hinge node 5 and converge inward under the traction of the connecting support rod 3. As the hydraulic drive control component 2 continues to retract, the rollable formwork system gradually degenerates from a curved shape conforming to the concrete to a semi-rolled state, until it finally returns to a compact closed state. During this process, the surface of the flat frame module 1 automatically detaches from the concrete structure, achieving contactless "inward demolding."

[0060] Compared to the traditional method of forcibly separating concrete using crowbars, the hydraulic automated demolding process used in this invention not only completely avoids damage to the edges and surface quality of fair-faced concrete caused by tools, but also eliminates the need for workers to enter narrow spaces for high-risk operations, greatly improving demolding efficiency and construction safety.

[0061] This invention can be further refined according to the shape of the concrete surface to meet the requirements for smoothness and precision. By reducing the width of the flat frame module 1 and introducing higher precision hydraulic drive control components 2 and their automated control system, in conjunction with displacement sensors and a central processing unit, the extension and retraction of each hydraulic drive control component 2 can be monitored and finely adjusted in real time, achieving millimeter-level precise control over the surface shape of the template formed by each plate frame module 1 of the rollable template system. This intelligent hydraulic automated drive not only ensures the synchronization and stability of the template during unfolding and rolling, but also dynamically adjusts the relative position and angle of each flat frame module 1 according to the design requirements of complex irregular curved surfaces, thereby ensuring that the final formed concrete structure has a smooth and flat surface with smooth and natural curves, achieving extremely high architectural aesthetics and engineering quality standards.

[0062] The present invention has the following beneficial effects:

[0063] A. Strong surface adaptability: Driven by hydraulic control components, multiple fixed template units and movable adjustment units move in tandem, achieving a continuous and smooth transition from a plane to a curved surface, thus solving the problem of difficult formwork support for irregular structures.

[0064] B. Automated demolding: Through its motion mechanism, the formwork can automatically curl and detach from the concrete surface after pouring, avoiding the damage to the edges and corners of the finished product caused by traditional demolding.

[0065] C. High precision and high rigidity coexist: The hydraulically driven control components ensure the accuracy of curved surface forming, taking into account both structural safety and engineering quality.

[0066] D. Extreme Compactness: The rollable template system has a rollable storage volume that is only 1 / 10 of its flattened state, which greatly reduces warehousing and transportation costs and does not require the assistance of large lifting equipment, thus improving the efficiency of site transfer.

[0067] E. Green and low-carbon: Fully dry assembly, nail-free construction, reusable hundreds of times, in line with the development trend of building industrialization and energy conservation and emission reduction.
