Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a foldable aluminum I-beam large template system. Background Art

[0002] In nuclear power plant construction, formwork engineering is a crucial step in concrete structure construction. With the continuous development of the construction industry, the requirements for construction efficiency, quality, and cost control are becoming increasingly stringent.

[0003] Traditional large formwork systems often have the following problems during use: for example, they are large in size, inconvenient to transport and store, and increase logistics costs and site occupancy; therefore, the industry urgently needs formwork systems that can reduce their size when not in use to save transportation and storage space. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem that the existing formwork system is large in size and inconvenient to transport and store, and to provide a foldable aluminum I-beam large formwork system. When not in use, the formwork system can be folded to reduce the volume of the formwork system and improve the convenience of transportation and storage of the formwork system.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A foldable aluminum I-beam large formwork system includes a foldable platform frame and a foldable support frame, the platform frame is movably mounted on the top of the support frame and is cantilevered; the platform frame includes a pedal and a connecting assembly, the support frame includes a vertical frame and a support rod group, the end of the pedal is hinged to the vertical frame, the connecting assembly is hinged to the pedal and the vertical frame respectively, and the support rod group is located below the pedal and hinged to the vertical frame; in the unfolded state, the pedal and the vertical frame are vertically arranged, and a triangular structure is formed between the support rod group and the vertical frame; in the retracted state, the connecting assembly and the support rod group are both rotated and folded toward the vertical frame, and the pedal and the vertical frame are arranged parallel.

[0007] The platform frame of the present invention is used for workers to step on and place necessary construction tools during construction; the support frame is used to provide support for the platform frame. Both the platform frame and the support frame are made into foldable structures. When not in use, the platform frame and the support frame can be folded at the same time, which greatly saves the transportation and storage space of the formwork system and facilitates transportation and handling. At the same time, the platform frame and the support frame always maintain a connected relationship, and there is no need to reinstall and disassemble, which simplifies the installation and disassembly process and improves the construction speed. The present invention uses an aluminum alloy structure support frame to replace the traditional wooden support frame. It can be repeatedly used, thereby reducing costs, and provides good bending and torsion resistance, ensuring the stability and reliability of the formwork system during use; the folding design of the components makes it take up little space during transportation and storage, convenient for handling and storage, and greatly improves logistics efficiency.

[0008] Furthermore, the connecting assembly includes a first connecting frame and a second connecting frame, the first connecting frame is parallel to the pedal and its end is hinged to the vertical frame, the second connecting frame is hinged to the pedal at one end, and the other end is hinged to the end where the first connecting frame and the pedal are hinged. The first connecting frame is arranged below the second connecting frame and the pedal, and the second connecting frame forms an inclined angle with the first connecting frame. By hingedly connecting the first connecting frame and the vertical frame, and hingedly setting the pedal to the vertical frame at the same time, the pedal can be spread out when in use, so that the pedal is perpendicular to the vertical frame and cantilevered, and workers can stand on the pedal for construction; when not in use, the pedal and the first and second connecting frames can be rotated and folded toward the vertical frame to greatly reduce the storage volume and improve the convenience of transportation and storage.

[0009] Furthermore, the platform frame includes a foldable protective mechanism, which is hingedly connected to the end of the step away from the upright frame and the end of the first connecting frame away from the upright frame. The protective mechanism is used to protect workers standing on the step from accidental falls. The protective mechanism is configured to be foldable and can be folded when not in use to reduce its storage volume.

[0010] Furthermore, the protective mechanism includes a plurality of guardrails hinged in sequence along the height direction and fasteners, wherein the fasteners are detachably connected to the guardrails. In the deployed state, the fasteners are inserted into two adjacent guardrails for fastening. In the stowed state, the fasteners are removed, and the guardrails are rotated and folded to be arranged parallel to the stand. The guardrails serve as guardrails for protection. The fasteners are used to connect and secure adjacent guardrails when in use. When not in use, the fasteners can be removed to rotate and fold the guardrails.

[0011] Furthermore, the support rod assembly includes a first support rod and a second support rod, one end of the first support rod and one end of the second support rod are both hinged to the stand, and the other end of the first support rod is detachably connected to the other end of the second support rod; in the deployed state, a triangular structure is formed between the first support rod, the second support rod, and the stand; in the retracted state, the connection between the first support rod and the second support rod is released, and the first support rod and the second support rod are both rotated and folded toward the stand. The first support rod and the second support rod work together to support the stand, forming a stable triangular structure with the stand, which can prevent the stand from tipping over during use.

[0012] Furthermore, the support rod assembly further includes a connecting member, and the first support rod and the second support rod are both rotatably connected to the connecting member via bolts. The connecting member serves as a transition between the first support rod and the second support rod, on the one hand increasing the ground contact area between the first support rod and the second support rod, thereby increasing friction, and on the other hand facilitating the installation and connection of the first support rod and the second support rod.

[0013] Furthermore, the vertical frame includes a plurality of horizontal beams and a plurality of longitudinal beams, the plurality of longitudinal beams being arranged in parallel and connected by the horizontal beams; the longitudinal beams being made of aluminum alloy. The horizontal beams serve as lateral supports, and the longitudinal beams serve as longitudinal supports, and the horizontal beams and the longitudinal beams are sequentially connected to form the vertical frame.

[0014] Furthermore, the stand also includes a panel connected to the crossbeam and / or the longitudinal beam by screws. Preferably, the panel is plywood, which improves the integrity of the crossbeam and the longitudinal beam and increases the strength and deformation resistance of the stand.

[0015] Furthermore, the frame also includes a top reinforcement assembly and a bottom reinforcement assembly. The top reinforcement assembly is installed at the top of the longitudinal beam, and the bottom reinforcement assembly is installed at the bottom of the longitudinal beam. The top reinforcement assembly connects to the crossbeam and longitudinal beam from the top of the frame, thereby increasing the strength of the top of the frame, reinforcing the overall stability of the entire formwork system and preventing it from twisting during lifting, transportation, and storage. Similarly, the bottom reinforcement assembly connects to the crossbeam and longitudinal beam from the bottom of the frame, thereby increasing the strength of the bottom of the frame, reinforcing the overall stability of the entire formwork system and preventing it from twisting during lifting, transportation, and storage.

[0016] Furthermore, the top reinforcement assembly includes two transversely arranged square tubes and a plurality of longitudinally arranged first vertical plates and a cover plate. The two square tubes are respectively connected to the two sides of the cover plate. The plurality of first vertical plates are arranged in parallel and are each connected to the two square tubes and the cover plate. Each first vertical plate is also detachably connected to each longitudinal beam. The bottom reinforcement assembly includes two transversely arranged angle steels and a plurality of longitudinally arranged second vertical plates. The plurality of second vertical plates are arranged in parallel and are each connected to the two angle steels. Each first vertical plate is also detachably connected to each longitudinal beam. The first vertical plates are placed at equal intervals with the longitudinal beams and connected using bolts, making the formwork system less likely to deform during construction. The second vertical plates are also placed at equal intervals with the longitudinal beams and connected using bolts. The upper and lower vertical plates simultaneously control the spacing between the longitudinal beams, making the formwork system less likely to deform during installation and construction. Using angle steel as the bottom support can reduce the contact area between the bottom of the stand and the ground, lowering the requirements for ground flatness at the construction site.

[0017] Furthermore, the first and second support rods that comprise the support rod assembly, as well as the platform frame's pedals and connecting frame, are all made of aluminum alloy. Aluminum's lightweight, high-strength, and corrosion-resistant properties make it an ideal formwork material. Aluminum crossbeams and longitudinal beams replace traditional wooden I-beams, allowing for multiple reuse and reducing costs. Aluminum also offers excellent bending and torsional resistance, ensuring the stability and reliability of the formwork system during use.

[0018] The beneficial effects of the utility model are:

[0019] Aluminum's lightweight, high-strength, and corrosion-resistant properties make it an ideal formwork material. This new formwork system offers excellent load-bearing capacity and stability. Amidst the increasing pursuit of efficiency, environmental friendliness, and sustainable development in construction, the foldable design offers significant advantages. The formwork system can be folded up when not in use, significantly reducing storage space and facilitating transportation and handling. It also simplifies installation and disassembly, speeding up construction.

[0020] In addition, with the diversification and complexity of architectural design, higher requirements are placed on the flexibility and adaptability of the formwork system. The foldable aluminum I-beam large formwork system of the present invention can better meet the construction requirements of concrete structures of different shapes and sizes.

[0034] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0035] Example 1

[0036] like Figures 1 to 9 The following is an embodiment of a foldable aluminum I-beam large template system of the utility model, as shown in FIG. Figure 1 and Figure 2 , including a foldable platform frame 1 and a foldable support frame 2, the platform frame 1 is movably installed on the top of the support frame 2 and is cantilevered; the platform frame 1 includes a pedal 11 and a connecting assembly 12, the support frame 2 includes a vertical frame 21 and a support rod group 22, the end of the pedal 11 is hinged to the vertical frame 21, the connecting assembly 12 is hinged to the pedal 11 and the vertical frame 21 respectively, and the support rod group 22 is located below the pedal 11 and hinged to the vertical frame 21; in the unfolded state, the pedal 11 and the vertical frame 21 are vertically arranged, and a triangular structure is formed between the support rod group 22 and the vertical frame 21; in the retracted state, the connecting assembly 12 and the support rod group 22 are both rotated and folded toward the vertical frame 21, and the pedal 11 and the vertical frame 21 are arranged parallel.

[0037] As an improvement to this embodiment, the connecting assembly 12 includes a first connecting frame 121 and a second connecting frame 122. The first connecting frame 121 is parallel to the pedal 11 and its end is hinged to the upright frame 21. The second connecting frame 122 is hinged to the pedal 11 at one end and hinged to the end where the first connecting frame 121 and the pedal 11 are hinged at the other end. The first connecting frame 121 is disposed below the second connecting frame 122 and the pedal 11. The second connecting frame 122 and the first connecting frame 121 form an inclined angle, similar to the structure of a tripod. By hingedly connecting the first connecting frame 121 and the second connecting frame 122 to the vertical frame 21, and hingedly connecting the pedal 11 to the vertical frame 21, the pedal 11 can be opened in the use state, i.e., the unfolded state, so that the pedal 11 is perpendicular to the vertical frame 21 and cantilevered, so that workers can stand on the pedal 11 for construction; in the non-use state, i.e., the folded state, the pedal 11 and the first connecting frame 121 and the second connecting frame 122 can be rotated and folded toward the vertical frame 21, thereby greatly reducing the storage volume and improving the convenience of transportation and storage. Figures 7 to 9 .

[0038] As an improvement to this embodiment, the platform frame 1 further includes a foldable protective mechanism 13, which is hingedly connected to the end of the pedal 11 away from the upright frame 21 and the end of the first connecting frame 121 away from the upright frame 21. The protective mechanism 13 is used to protect workers standing on the pedal 11 during construction to prevent accidental falls. The protective mechanism 13 is configured as a self-folding structure and can be folded even when not in use to reduce its storage volume. The first connecting frame 121, the second connecting frame 122, and the guardrail 131 form a single unit, providing excellent strength.

[0039] As an improvement to this embodiment, the protective mechanism 13 includes a plurality of guardrails 131 and fasteners 132 that are hinged in sequence along the height direction. The fasteners 132 are detachably connected to the guardrails 131. In the expanded state, the fasteners 132 are connected to two adjacent guardrails 131 for fastening. In the retracted state, the fasteners 132 are removed, and the guardrails 131 are rotated and folded to be arranged parallel to the stand 21. The guardrails 131 serve as guardrails and provide protection. The fasteners 132 are used to connect and secure adjacent guardrails 131 when in use, i.e., in the expanded state. When not in use, i.e., in the folded state, the fasteners 132 can be removed and the guardrails 131 can be rotated and folded. Figures 7 to 9 Preferably, a frame protection mesh is provided between the guardrails 131, and the protection mechanism 13 is a folding structure that can be folded in half in the height direction.

[0040] As an improvement to this embodiment, the support rod assembly 22 includes a first support rod 221 and a second support rod 222. One end of the first support rod 221 and one end of the second support rod 222 are both hinged to the stand 21, and the other end of the first support rod 221 is detachably connected to the other end of the second support rod 222. In the unfolded state, a triangular structure is formed between the first support rod 221, the second support rod 222, and the stand 21. In the retracted state, the connection between the first support rod 221 and the second support rod 222 is released, and the first support rod 221 and the second support rod 222 are both rotated and folded toward the stand 21. The first support rod 221 and the second support rod 222 work together to support the stand 21, forming a stable triangular structure with the stand 21, which can prevent the stand 21 from tipping over during use.

[0041] As an improvement to this embodiment, the support rod assembly 22 further includes a connector 223, with the first support rod 221 and the second support rod 222 both being rotatably connected to the connector 223 via bolts. The connector 223 serves as a transition between the first support rod 221 and the second support rod 222. This connector not only increases the contact area between the first support rod 221 and the second support rod 222, thereby increasing friction, but also facilitates the installation and connection of the first support rod 221 and the second support rod 222. The first support rod 221 and the second support rod 222 work together to support the stand 21, forming a stable triangular structure with the stand 21 to prevent the stand 21 from tipping over during use.

[0042] As an improvement to this embodiment, the first and second support rods 221, 222 of the support rod assembly 22, and the platform 11 and connecting frame of the platform frame 1 are all made of aluminum alloy. Aluminum's advantages, such as light weight, high strength, and corrosion resistance, make it an ideal formwork material. Aluminum replaces traditional wood materials and can be reused multiple times, thus reducing costs. Furthermore, aluminum offers excellent bending and torsional resistance, ensuring the stability and reliability of the formwork system during use.

[0043] As an improvement to this embodiment, a safety belt tie rod 4 is further included, which is made of steel and passes through multiple longitudinal beams 212. Anti-drop bolts are provided at both ends of the safety belt tie rod 4. When construction workers lose their balance during installation, disassembly or maintenance work on the formwork system, the safety belt tie rod 4 can prevent them from falling.

[0044] Example 2

[0045] This embodiment is Example 2 of a foldable aluminum I-beam large formwork system. This embodiment is similar to Example 1, except that the vertical frame 21 includes multiple crossbeams 211 and multiple longitudinal beams 212. The multiple longitudinal beams 212 are arranged in parallel and connected through the crossbeams 211; the longitudinal beams 212 are made of aluminum alloy. The crossbeams 211 serve as horizontal supports, and the longitudinal beams 212 serve as longitudinal supports. The crossbeams 211 and the longitudinal beams 212 are connected to each other in sequence to form the vertical frame 21. The first support rod 221 is connected to the crossbeams 211 and / or the longitudinal beams 212 by a rotating lock, which facilitates the first support rod 221 and the second support rod 222 to rotate and fold toward the vertical frame 21 when not in use. Aluminum alloy materials have the advantages of light weight, high strength, and corrosion resistance.

[0046] As an improvement to this embodiment, the stand 21 further includes a panel 213, which is connected to the crossbeam 211 and / or the longitudinal beam 212 via screws. Preferably, the panel 213 is plywood, which is connected to the crossbeam 211 and / or the longitudinal beam 212 using nails. The panel 213 improves the integrity of the crossbeam 211 and the longitudinal beam 212, thereby increasing the strength and deformation resistance of the stand 21.

[0047] As an improvement to this embodiment, the upright frame 21 also includes a top reinforcement assembly 214 and a bottom reinforcement assembly 215. The top reinforcement assembly 214 is mounted on the top of the longitudinal beam 212, while the bottom reinforcement assembly 215 is mounted on the bottom of the longitudinal beam 212. The top reinforcement assembly 214 connects to the crossbeam 211 and longitudinal beam 212 from the top of the upright frame 21, thereby increasing the strength of the top of the upright frame 21 and reinforcing the overall stability of the formwork system, preventing it from twisting during lifting, transport, and storage. Similarly, the bottom reinforcement assembly 215 connects to the crossbeam 211 and longitudinal beam 212 from the bottom of the upright frame 21, thereby increasing the strength of the bottom of the upright frame 21 and reinforcing the overall stability of the formwork system, preventing it from twisting during lifting, transport, and storage. The top reinforcement assembly 214 and the bottom reinforcement assembly 215 also provide support and fixing, ensuring the stability of the formwork system during construction and preventing it from shifting or deforming. During installation and disassembly, they provide guidance and positioning, making operation more precise and convenient.

[0048] As an improvement to this embodiment, several hooks 3 are provided on the top reinforcement assembly 214 to facilitate lifting. The U-plates of the hooks 3 are bolted to the longitudinal beams 212 or the top reinforcement assembly 214, which provides a more even distribution of force. The U-shaped direction of the hooks 3 is parallel to the direction of the panel 213, which allows for a more reasonable distribution of the lifting force of the formwork system and prevents the uprights 21 from moving due to lifting.

[0049] Example 3

[0050] This embodiment is a folding aluminum I-beam large formwork system. This embodiment is similar to the first embodiment, except that Figure 4 and Figure 5 As shown, the top reinforcement assembly 214 includes two transversely arranged square tubes 2141, multiple longitudinally arranged first vertical plates 2142, and a cover plate 2143. The two square tubes 2141 are respectively connected to the two sides of the cover plate 2143. Multiple first vertical plates 2142 are arranged in parallel and are each connected to the two square tubes 2141 and the cover plate 2143. Each first vertical plate 2142 is also detachably connected to each longitudinal beam 212. The bottom reinforcement assembly 215 includes two transversely arranged angle steels 2151 and multiple longitudinally arranged second vertical plates 2152. Multiple second vertical plates 2152 are arranged in parallel and are each connected to the two angle steels 2151. Each first vertical plate 2142 is also detachably connected to each longitudinal beam 212. The first vertical plates 2142 and the longitudinal beams 212 are arranged at equal intervals and connected with bolts, which prevents deformation of the formwork system during construction. Second vertical plates 2152 are also placed at equal distances from longitudinal beams 212 and connected with bolts. These two vertical plates simultaneously control the spacing between longitudinal beams 212, preventing deformation during formwork installation and construction. Using angle steel 2151 as the bottom support reduces the contact area between the bottom of the vertical frame 21 and the ground, lowering the requirements for ground flatness at the construction site.

[0051] Compared to non-foldable formwork systems, the same number of foldable aluminum I-beam large formwork systems can be stored more compactly. The regular shape of the folded formwork system makes it easier to sort, stack and count, facilitating inventory management.

[0052] This new foldable aluminum I-beam formwork system offers the advantages of lightweight construction: Compared to traditional steel formwork, aluminum has a lower density, significantly reducing its weight, making it easier to handle and install, and reducing labor intensity. It also boasts high strength: Despite its light weight, aluminum possesses exceptional strength, capable of withstanding significant concrete pressure, ensuring stability and safety during construction. It is also corrosion-resistant: Aluminum's excellent corrosion resistance makes it less susceptible to rust in humid environments or after prolonged use, extending the lifespan of the formwork system. It is also easy to store and organize: The formwork system's components are designed to fold, requiring only initial assembly. The folded components can then be unfolded during subsequent construction, significantly reducing the time required for repeated installation and significantly reducing the space required for storage, storage, and transportation. It also boasts excellent flatness: This ensures the casting of concrete components with a smooth and even surface, enhancing the building's appearance and precision. It is highly reusable: Due to the unique characteristics of its material and structure, the formwork system can be reused multiple times with proper maintenance, reducing construction costs. It is also easy to assemble: Its design is generally well-designed, making assembly simple and quick, thereby improving construction efficiency. Energy saving and environmental protection: Aluminum has a high recycling rate, which meets the requirements of modern construction for energy saving and environmental protection.

[0053] In some large-scale infrastructure construction projects, the strength and stability of the formwork system are extremely high, and quick installation and disassembly are required to shorten the construction period. The folding aluminum I-beam large formwork system of this utility model has also been widely used in these fields due to its excellent performance.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
