Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and particularly relates to an assembled steel bar formwork floor composite component. Background Art

[0002] In traditional building construction techniques, the floor construction process faces various challenges and deficiencies, which are specifically reflected in the following aspects: (1) Complicated steel bar processing and installation: As key load-bearing and crack-resistant elements in the floor structure, the processing of steel bars includes steps such as cutting, bending, and welding. Most of these operations rely on manual or semi-automatic tools, which are not only time-consuming and laborious, but also difficult to guarantee accuracy, affecting the overall quality and safety of the structure. (2) Formwork erection and fixing problems: On-site formwork erection is a labor-intensive process that requires precise measurement and positioning. However, due to human factors, it is difficult to achieve absolute accuracy. Loose formwork fixing will cause displacement during concrete pouring, affecting the flatness and dimensional accuracy of the floor, and may lead to potential structural safety hazards in severe cases. (3) Efficiency and quality of steel bar binding: The labor intensity of steel bar binding work is high, and the binding quality is greatly affected by the skills of workers. Problems such as loose binding and uneven spacing are likely to occur, affecting the load-bearing capacity and durability of the floor.

[0003] In addition, in traditional pouring operations, the transportation and vibration of concrete require a large amount of manpower and time, and the formwork removal usually needs to wait until the concrete reaches a certain strength. This process has a long cycle, occupies a large amount of scaffolding and formwork materials, and affects the progress of subsequent processes. Moreover, the traditional full-span scaffolding setting not only consumes a large amount of materials, has heavy erection and removal work, but also occupies the construction space, restricts the flexibility of on-site operations, and increases potential safety hazards.

[0004] Due to low construction efficiency and low material recycling rate, traditional construction methods are prone to cause a large amount of waste of resources such as wood and steel, and at the same time, the generated construction waste puts pressure on the environment. The on-site operation environment is complex, and there are high safety risks in high-altitude operations, heavy object handling and other links. Coupled with the high labor intensity of workers and easy fatigue, the probability of safety accidents increases. Traditional construction methods rely mainly on manual operations, with low mechanization degree, and fail to make full use of the efficiency improvement brought by the progress of modern building technologies, resulting in low overall construction efficiency. In summary, traditional floor construction techniques have obvious deficiencies in terms of efficiency, accuracy, safety, and environmental protection. There is an urgent need for technological innovation and process reform, such as adopting precast components, intelligent equipment, new formwork systems, etc., to improve construction efficiency, ensure project quality, reduce the labor intensity of workers, and promote the sustainable development of the construction industry.

[0005] Therefore, there is an urgent need for a prefabricated reinforced formwork floor composite component to solve the problems of inaccurate positioning and fixing of steel bars, long formwork removal cycle, high safety risks, high labor intensity, and insufficient mechanization level, which lead to low overall construction efficiency. Summary of the Invention

[0006] For this reason, the present utility model provides a prefabricated reinforced formwork floor composite component to solve the problems of high safety risks and low overall construction efficiency caused by inaccurate positioning and fixing of steel bars and long formwork removal cycle in the prior art.

[0007] In order to achieve the above object, the present utility model provides the following technical solutions:

[0008] According to the first aspect of the present utility model, a prefabricated reinforced formwork floor composite component is provided, including a concrete formwork, a connecting member, and a truss. The concrete formwork is connected to the connecting member by self-tapping screws, and the connecting member is snap-connected to the truss.

[0009] Further, the concrete formwork is a non-removable formwork.

[0010] Further, the width of the concrete formwork does not exceed 1200 mm.

[0011] Further, the length of the concrete formwork and the height of the truss can be adjusted according to the on-site needs.

[0012] Further, a plurality of self-tapping screws arranged in a straight line are provided at the connection between the connecting member and the bottom plate.

[0013] Further, the truss is an angular truss composed of upper main bars, lower main bars, and web members connected end to end between the upper main bars and the lower main bars.

[0014] Further, the truss is made of steel bars.

[0015] The present utility model has the following advantages:

[0016] 1. Innovative structural design: The non-removable concrete formwork with bottom waterproofing is directly used to replace the traditional plastering layer, which not only avoids material loss but also ensures the long-term use and waterproof performance of the formwork. Through the precisely designed special connecting member, the thickness of the steel bar protection layer is strictly controlled. At the same time, the use of triangular steel bar trusses significantly enhances the structural stability, effectively inhibits the phenomena of slurry leakage and formwork bulging during pouring, reduces the need for external supports, and greatly promotes the realization of the "no support" construction concept.

[0017] 2. High-efficiency and green construction: By transferring a large number of on-site operations to prefabrication in the factory, this plan significantly improves the project quality and construction efficiency, reduces on-site material waste and environmental pollution, and lowers safety risks. The highly prefabricated and mechanized production mode greatly enhances labor productivity, making high-altitude and facade construction as convenient as ground operations, and realizing the dream of efficient construction in modern building industrialization.

[0018] 3. Wide applicability: The design of this floor slab structure without formwork is flexible and widely applicable to various building types, including shear wall structures, frame structures, steel structures, and rural civil residences, showing strong adaptability and promotion value, and providing a one-stop high-quality solution for different building needs.

[0025] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present invention provides a prefabricated reinforced formwork floor composite component, as Figure 1 and Figure 2 shown, which includes a concrete formwork 1, a connecting member 2, and a truss 3. The concrete formwork 1 is connected to the connecting member 2 by self-tapping screws 4, and the connecting member 2 is snap-connected to the truss 3.

[0027] The truss 3 is composed of upper main reinforcement bars, lower main reinforcement bars, and web members tightly connected between the two. The web members are connected end to end according to a specific geometric arrangement, forming a strong and lightweight support grid, effectively improving the load-bearing capacity and anti-deformation performance of the floor slab. The concrete formwork 1 is made of high-quality materials, ensuring good casting surface quality and durability. The surface of the concrete formwork 1 is smooth and the dimensions are precise, facilitating close combination with the concrete to form a flat and uniform floor slab surface. The concrete formwork 1 and the special connecting member 2 are tightly connected by high-strength self-tapping screws 4. This connection method not only simplifies the on-site installation steps but also ensures the stability and reliability of the connection, and can maintain the structural integrity even during long-term use. The design of the connecting member 2 not only forms a stable assembly relationship with the concrete formwork 1 through self-tapping screws 4 but also tightly engages with the truss 3 through a snap connection structure. This snap connection design not only ensures the possibility of rapid assembly but also effectively transfers the load, avoiding displacement and loosening during the construction process and improving the overall structural stability.

[0028] The prefabricated reinforced formwork floor composite component of the present invention provides an efficient, economical, and safe solution for modern building construction through the optimized design of the truss 3, efficient connection methods, and high-quality concrete formwork 1. It significantly shortens the construction period, reduces the labor intensity, reduces on-site wet operations, and improves the building quality at the same time. It is an important technological progress in promoting the industrialization and standardization process of construction.

[0029] Specifically, the concrete formwork 1 is a non-removal formwork, and its design not only integrates excellent waterproof performance, effectively preventing the adverse effects of water penetration on structural safety and durability, but also completely subverts the cumbersome process of traditional formwork that needs to be removed after concrete pouring and curing. The core advantage of this design is that it can be a permanent part of the building structure and share the load with concrete, thus completely eliminating the time-consuming and labor-intensive subsequent processes such as disassembly, transportation and cleaning of the formwork in traditional construction.

[0030] By adopting the non-removal formwork, the construction process has been significantly simplified, and the direct economic benefits are reflected in several key aspects: first, it greatly shortens the construction period, improves the overall construction efficiency, and enables the project to advance to the next stage more quickly; second, it greatly reduces manpower requirements and labor costs, because a large amount of manpower is no longer required to dismantle and recycle the formwork; third, it saves the repeated purchase cost and rental fee of formwork materials, and also reduces the transportation and storage expenses of formwork; finally, it reduces the generation of construction waste, which is in line with the current concept of environmentally friendly construction and reduces the impact on the environment.

[0031] In addition, the application of non-removal formwork also reduces the risk of structural damage caused by improper formwork removal during construction, improving the overall quality and safety of the building structure. From a long-term perspective, the durability and low-maintenance characteristics of this formwork material also facilitate the long-term use and maintenance of the building, further verifying its advancement and practicality in modern construction technology.

[0032] Specifically, the width of the concrete formwork 1 does not exceed 1200 mm. This design complies with the building construction specifications, and helps to limit the width of the formwork, helps to reduce the weight of a single formwork, facilitates on-site transportation and installation, reduces safety hazards caused by overweight formwork, and ensures the safety of transportation and stability of installation during construction personnel's operation. It also helps to improve the overall stability of the formwork system, avoid deformation or breakage of over-wide formwork due to deadweight or vibration during concrete pouring, and ensure the accuracy of the size of concrete components and the flatness of the surface.

[0033] Specifically, the prefabricated reinforced formwork floor composite component mentioned in the present invention fully considers the diversity and flexibility requirements of the actual construction site in its design. Both the formwork length and the height of the truss 3 can be customized and adjusted according to the actual dimensions and structural requirements of specific projects. This means that in different building design and construction environments, whether facing irregular building floor plans or changes in load requirements in specific areas, this composite component can achieve precise adaptation. The adjustability of the formwork length ensures that for large-area floors with long spans or local floor laying in narrow spaces, seamless splicing can be achieved by selecting or cutting concrete formwork 1 of appropriate length, which not only meets the continuity and stability of the structure but also avoids material waste.

[0034] This design flexibility significantly improves the construction convenience and efficiency, reduces on-site cutting work, and makes the construction process smoother and more efficient. The height adjustment function of the truss 3 is based on the refined consideration of the floor bearing capacity and structural safety. According to the floor thickness, span, expected load, and building code requirements, engineers can pre-calculate and set the most suitable height of the truss 3 to ensure that the mechanical properties of the floor structure reach the optimal state. This design can not only enhance the load-bearing capacity of the floor but also optimize the material use without affecting the overall stability, achieving a perfect balance between economy and safety. In short, through the adjustable design of the formwork length and the height of the truss 3, the prefabricated reinforced formwork floor composite component of the present invention achieves wide adaptability to various complex building environments, ensuring construction flexibility, economy, and structural reliability, which is a major innovative practice in the modern building field.

[0035] Specifically, a plurality of self-tapping screws 4 arranged linearly are provided at the connection between the connecting member 2 and the bottom plate, as Figure 3 shown. This design ensures the connection stability and adaptability. At the connection between the connecting member 2 and the bottom plate, a plurality of self-tapping screws 4 arranged linearly are used to fix the two. Such a design not only simplifies the installation process and improves work efficiency but also effectively disperses the stress concentration in the connection area and enhances the overall structural stability and reliability by increasing the number of self-tapping screws 4 and adopting a linear arrangement. However, for different application scenarios or specific installation requirements, this design also reserves adjustment space. For example, the number and arrangement density of the self-tapping screws 4 can be adjusted according to the actual load requirements or the characteristics of the bottom plate material to meet higher strength requirements or adapt to different installation conditions.

[0036] Meanwhile, the layout pattern of the self-tapping screws 4 can also be flexibly changed. For example, it can be adjusted to a staggered arrangement according to the actual situation to further enhance the connection firmness and the ability to resist shear force. In addition, the selection of the self-tapping screws 4 also takes into account their materials and specifications to ensure durability and corrosion resistance in different environments (such as humid or corrosive environments), thereby extending the service life of the components. For occasions that require higher-strength connections, a larger diameter of the self-tapping screws 4 may be selected or high-strength self-tapping screws 4 with special designs may be adopted.

[0037] In summary, through the flexible adjustment of the quantity, arrangement mode, and type of the self-tapping screws 4, this design achieves the adaptation to various complex working conditions, ensures the stable connection and long-term performance of the assembled reinforced concrete formwork floor components in practical applications, and demonstrates its high practicality and flexibility.

[0038] In the present invention, the truss 3 structure adopted is a triangular truss. The triangular truss is composed of upper main bars, lower main bars, and web members that are interconnected and staggered between them, forming a series of continuous and closely arranged triangular structural units. Each triangular structural unit can independently bear external forces from different directions, effectively distribute and transfer loads, thereby ensuring the stability and load-bearing capacity of the entire floor system.

[0039] During specific implementation, the upper main bars and lower main bars of the triangular truss 3 are usually made of high-strength steel to ensure sufficient stiffness and load-bearing capacity. The web members, through precise angle and length settings, optimize the mechanical properties of the entire truss 3 system, making it perform better when bearing vertical loads and lateral shear forces.

[0040] The triangular truss 3 adopted in the present invention, through its inherent stable structure design, precise mechanical calculations, and flexible adaptability adjustments, provides a strong support system for the assembled reinforced concrete formwork floor, not only enhancing the safety and durability of the building, but also optimizing the construction efficiency and cost-effectiveness.

[0041] The truss 3 in the present invention is made of high-quality steel bar materials. This choice is based on the high strength, good ductility, and well-tested reliability of the steel bar materials in building structures. The high-strength steel bar materials ensure that the truss 3 can maintain its structural stability and load-bearing capacity under complex load conditions. The selection of the steel bar materials not only needs to meet the basic mechanical property requirements, such as yield strength, tensile strength, etc., but also needs to consider its bonding performance and corrosion resistance in concrete.

[0042] Therefore, the steel bars used for the truss 3 can be subjected to special surface treatments according to needs, such as galvanizing treatment, to enhance its corrosion resistance and extend its service life, especially when applied in humid or harsh environments.

[0043] In summary, the truss 3 made of steel bars in the present invention is based on its excellent mechanical properties and wide adaptability in practical applications, aiming to create an assembled steel formwork floor structure system that is both safe and reliable and economical and efficient, meeting the comprehensive requirements of modern buildings for high quality, rapid construction and long-term durability.

[0047] 2. Quick connection mechanism: The concrete formwork 1 is tightly connected to the special connecting piece 2 through self-tapping screws 4. This connection method is simple and fast, ensuring the stability of the formwork and the support system.

[0048] 3. Structural adaptability: The length of the formwork and the height of the truss 3 can both be adjusted according to the actual engineering requirements. This flexibility enables this composite component to adapt to floor slab designs with different sizes and load requirements, enhancing the flexibility and application range of construction.

Through the reasonable layout of the upper main reinforcement, lower main reinforcement and web members, it can effectively disperse and transfer loads, ensuring the stability and safety of the floor slab structure.

[0050] 5. Fine connection details: There are multiple self-tapping screws 4 arranged in a straight line at the connection between the connecting piece 2 and the bottom plate. This layout method not only enhances the stability of the connection, but also improves the construction efficiency, ensuring the stability of the entire structure without shaking.
