Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction technology, specifically to a stepped independent foundation formwork system. Background Technology
[0002] In the field of building construction, cost control of formwork engineering in the construction of isolated foundations has always been an important issue. Traditionally, wooden formwork has been widely used in the construction of isolated foundations due to its relatively low cost and ease of processing.
[0003] However, with the development of the construction industry and the increasing demands for refined cost management, timber formwork construction has exposed many problems. First, the reuse rate of timber formwork is limited. Generally, after 3-5 uses, the surface flatness and dimensional accuracy of timber formwork deteriorate significantly, failing to meet construction requirements and necessitating replacement or repair, which greatly increases material costs. Second, the fabrication and installation of timber formwork is complex, requiring a high level of worker skill. Fabrication involves cutting and splicing according to the shape and size of the foundation, and installation also requires considerable time for positioning and securing, resulting in high labor costs. Third, timber formwork is easily damaged during removal, especially when the concrete is tightly bonded to it. Forced removal not only damages the formwork but may also damage the foundation surface, requiring additional repairs later, further increasing costs. Furthermore, with increasingly stringent environmental policies, the acquisition and use of timber resources are subject to numerous restrictions, and timber prices continue to rise, further increasing the material costs of timber formwork construction.
[0004] In summary, traditional wooden formwork construction methods have significant shortcomings in terms of cost control, construction efficiency, and environmental protection. There is an urgent need to develop a new formwork technology to overcome these shortcomings and meet the construction industry's demands for high efficiency, low cost, and environmental protection.

[0028] Please see Figure 1 , Figure 2This utility model provides a stepped independent foundation formwork system, including a first-stage aluminum alloy formwork 1 and a second-stage aluminum alloy formwork 2. Both the first-stage and second-stage aluminum alloy formwork 1 and 2 are made of aluminum alloy material, offering advantages such as high strength, relatively light weight, and high reusability. Compared to traditional wooden formwork, it effectively solves the problems of low reusability and limitations caused by timber resources. The second-stage aluminum alloy formwork 2 is erected above the first-stage aluminum alloy formwork 1 via several longitudinal support members 3, providing reliable support for its placement. The second-stage aluminum alloy formwork 2 is placed solely on the longitudinal support members 3 without being connected or fixed to them; the longitudinal support members 3 are then directly placed into the poured concrete. The outer walls of the four sides of the second-stage aluminum alloy formwork 2 are equipped with several side formwork diagonal braces 4 that connect to the inner walls of the side formwork corresponding to those of the first-stage aluminum alloy formwork 1. One end of each side formwork diagonal brace 4 is connected to the second-stage aluminum alloy formwork 2, and the other end is connected to the first-stage aluminum alloy formwork 1. The connection is ensured to be firm by welding or bolting, which can enhance the overall stability of the formwork system and resist the lateral pressure generated during concrete pouring. The two sets of opposite side forms of the second-stage aluminum alloy formwork 2 are fixed by tie rods 5 to ensure reliable reinforcement of the side forms of the second-stage aluminum alloy formwork 2 during construction.
[0029] The construction steps of the stepped independent foundation formwork system are as follows: First, install the first-stage aluminum alloy formwork 1 at the designed position. Then, place the longitudinal support 3 at the bottom of the erection position of the second-stage aluminum alloy formwork 2. Next, place the second-stage aluminum alloy formwork 2 on the longitudinal support 3. Then, reinforce the second-stage aluminum alloy formwork 2 with tie rods 5. Finally, install the side formwork diagonal bracing 4 between the side formwork of the first-stage aluminum alloy formwork 1 and the side formwork of the second-stage aluminum alloy formwork 2.
[0030] The construction steps of the aforementioned stepped independent foundation formwork system are clear and straightforward, and the installation of each component is simple and quick. Compared to traditional wooden formwork construction, the operational difficulty of each step is reduced, the connections are smooth, and the overall construction time is significantly shortened, greatly improving the construction speed. This allows the project to move to the next stage more quickly, effectively shortening the construction period and creating favorable conditions for the early completion of the entire project. Due to the simple process, the requirements for worker skill are relatively lower, and ordinary workers can operate the system after simple training. At the same time, the faster construction speed means less time spent on manual labor, which directly reduces the project's labor costs. It is estimated that labor costs are significantly lower compared to traditional wooden formwork construction. In addition, workers do not need to perform complex cutting, splicing, and heavy handling of wooden formwork as in traditional construction, greatly reducing labor intensity and improving worker motivation and construction safety.
[0031] In this embodiment, the stepped independent foundation formwork system, constructed from a first-stage aluminum alloy formwork 1, a second-stage aluminum alloy formwork 2, longitudinal supports 3, side formwork diagonal braces 4, and tie rods 5, provides several advantages. First, it ensures safe and reliable pouring conditions for the independent foundation platform, enabling the formwork system to effectively resist pressure during concrete pouring, guaranteeing the stability and sealing of the formwork, and thus avoiding common quality problems such as grout leakage and deformation. Second, the significantly reduced installation and dismantling time minimizes the interference of the formwork on the concrete forming process, resulting in excellent concrete forming quality and a high rate of qualified cross-sectional dimensions. This effectively reduces concrete waste caused by dimensional deviations, further saving costs, while improving the overall quality of the project, reducing subsequent repairs and rework, and enhancing the overall project quality. Third, it reduces reliance on timber by using environmentally friendly materials such as aluminum alloy formwork, complying with current environmental policies. The aluminum alloy materials are recyclable, reducing the consumption of natural resources and minimizing environmental pressure caused by timber felling and processing during construction. This has significant environmental benefits and promotes the green and sustainable development of the construction industry.
[0032] Please see Figure 3 In one embodiment, the longitudinal support 3 includes a support sleeve 31 and a triangular base 32 made of steel bars. The lower end of the support sleeve 31 is fitted over the top steel bar of the triangular base 32 and welded to it. The second-stage aluminum alloy formwork 2 is placed on top of the support sleeve 31. Through the combination of the support sleeve 31 and the triangular base 32, the longitudinal support 3 has a more stable structure and can better withstand the weight of the second-stage aluminum alloy formwork 2 and the pressure generated during concrete pouring, thereby improving the stability of the entire formwork system. The steel bars and sleeves used in the longitudinal support 3 are surplus materials from the production of other components, achieving resource reuse and reducing costs. Furthermore, the triangular base 32 can be welded on-site using leftover materials, and the welding method is simple and easy for construction personnel to master, effectively reducing the production cost and time of the longitudinal support 3.
[0033] In one embodiment, at least one longitudinal support 3 is provided at the bottom of each side formwork of the second-stage aluminum alloy formwork 2. By providing longitudinal support 3 at the bottom of each side formwork of the second-stage aluminum alloy formwork 2, it can be ensured that the formwork is subjected to uniform stress during concrete pouring, avoiding deformation or damage caused by excessive local stress.
[0034] In one embodiment, four longitudinal support members 3 are provided, and the four longitudinal support members 3 are respectively located at the bottom four corners of the second-stage aluminum alloy template 2. By placing the four longitudinal support members 3 at the bottom four corners of the second-stage aluminum alloy template 2, the optimal support effect can be formed, ensuring the stability of the template in all directions.
[0035] Please see Figure 4 In one embodiment, the side formwork bracing member 4 includes a vertical reinforcing bar 41, a horizontal reinforcing bar 42, and a diagonal bracing bar 43. One end of the horizontal reinforcing bar 42 and the diagonal bracing bar 43 are respectively connected to the same side of the vertical reinforcing bar 41, and the diagonal bracing bar 43 is located above the horizontal reinforcing bar 42. The side of the vertical reinforcing bar 41 away from the horizontal reinforcing bar 42 and the diagonal bracing bar 43 is connected to the inner wall of the side formwork of the first-stage aluminum alloy formwork 1. The other end of the horizontal reinforcing bar 42 is connected to the bottom of the side formwork of the second-stage aluminum alloy formwork 2, and the other end of the diagonal bracing bar 43 is connected to the outer wall of the side formwork of the second-stage aluminum alloy formwork 2. The included angle between the horizontal reinforcing bar 42 and the diagonal bracing bar 43 is 45°. Through the combination of the vertical reinforcing bar 41, the horizontal reinforcing bar 42, and the diagonal bracing bar 43, the side formwork bracing member 4 forms a stable triangular support structure, which effectively enhances the connection stability between the first-stage and second-stage aluminum alloy formwork 2 and resists the lateral pressure generated during concrete pouring. By setting the included angle between the horizontal reinforcing bar 42 and the diagonal bracing bar 43 to 45°, the diagonal bracing is subjected to more uniform stress, reducing stress concentration and improving its load-bearing capacity and service life. At the same time, the side formwork diagonal bracing member 4 has simple components, is easy to process and install, and can quickly complete the reinforcement of the formwork, improving construction efficiency.
[0036] Please see Figure 2 In one embodiment, the tie rod assembly 5 includes two opposing transverse square tubes 51 and a plurality of tie bolts 52. The two transverse square tubes 51 are respectively disposed on the outer sides of the two opposing side molds of the second-stage aluminum alloy template 2, and are fastened to the two opposing side molds of the second-stage aluminum alloy template 2 by the plurality of tie bolts 52. By fastening the two transverse square tubes 51 to the side molds of the second-stage aluminum alloy template 2 with the tie bolts 52, a reliable reinforcement system is formed, which not only has high on-site processing efficiency, but also ensures that the side molds of the second-stage aluminum alloy template 2 play a reliable reinforcement role during construction.
[0037] Please see Figure 1 , Figure 2 In one embodiment, each side of the first-stage aluminum alloy formwork 1 is provided with multiple side support steel bars 6 arranged in parallel on the outside of each side formwork. The side support steel bars 6 can further enhance the overall stability of the formwork, resist the lateral pressure and deformation generated during concrete pouring, and enable the formwork to withstand greater concrete weight and pressure.
[0038] Please see Figure 1In one embodiment, two adjacent side molds of the first-stage aluminum alloy formwork 1 are connected by a first right-angle connector 11, which is bolted to the side mold of the first-stage aluminum alloy formwork 1. Similarly, two adjacent side molds of the second-stage aluminum alloy formwork 2 are connected by a second right-angle connector 21, which is bolted to the side mold of the second-stage aluminum alloy formwork 2. The right-angle connectors and bolted connections simplify and expedite the installation and disassembly of the formwork. Construction workers can quickly assemble adjacent side molds and secure them with bolts, significantly reducing construction time. During disassembly, the side molds can be separated simply by loosening the bolts, facilitating reuse and transportation of the formwork. Furthermore, the side molds and right-angle connectors of both the first-stage and second-stage aluminum alloy formwork 1 and 2 are custom-made by the manufacturer to precise dimensions, eliminating the need for complex on-site processing. This greatly shortens the overall construction time, significantly increases construction speed, and allows the project to proceed to the next stage more quickly, creating favorable conditions for the early completion of the entire project.
