Description

Technical Field

[0001] The utility model belongs to the technical field of the prefabricated building industry, and particularly relates to a general aluminum formwork system for prefabricated components of prefabricated buildings. Background Art

[0002] The prefabricated component industry of prefabricated buildings is one of the industries that have developed rapidly in recent years. The following is an overview of the current situation, level and development trend of the prefabricated component and supporting mold industries:

[0003] (1) Industry Status

[0004] Due to the slowdown in the development speed of the real estate industry, the growth rate of the newly started area of prefabricated buildings in China has also decreased. However, due to the advantages of prefabricated buildings such as convenient assembly and low cost, the overall still shows a continuous growth trend.

[0005] The entry threshold of the prefabricated component industry of prefabricated buildings is relatively low, and the market competition is fierce. Many enterprises have flocked into this industry, resulting in problems such as overcapacity and frequent price wars.

[0006] With the continuous progress of technology, the production processes and equipment of prefabricated components are constantly updated, and the product quality and production efficiency are constantly improved. At the same time, the application of new technologies such as intelligentization, greenization and standardization has also promoted the technological progress of the industry.

[0007] (2) Industry Level

[0008] At present, due to the inability to unify the technical standards and building styles of each construction unit, the standardization degree of prefabricated components is not high, and there is no unified standard for the design of each mold factory. As a result, the standardization degree of prefabricated component molds is low and the versatility is poor. After the production of molds for prefabricated components with large sizes and large weights, the molds can only be scrapped. At present, most prefabricated component molds are made of steel, and the moisture in the concrete during the use of the molds will cause rust problems. With the intensification of market competition, enterprises' attention to product quality and cost is constantly increasing.

[0009] (3) Development Trend

[0010] With the improvement of environmental awareness, green development will become an important trend in the prefabricated component industry of prefabricated buildings. Enterprises will strengthen the application of environmental protection technologies, promote the use of environmental protection materials and production processes, reduce energy consumption and emissions, and improve the environmental protection performance of products. Under the process of industrialization, building materials can be mass-produced, which can reduce the number of laborers. The prefabricated building industry adapts to the overall development trend and will also develop rapidly. The standardized aluminum formwork system for prefabricated components can be widely used in the production of prefabricated components, reduce resource waste, and improve the quality of components.

[0032] Compared with the prior art, the present utility model has the following beneficial effects:

[0033] 1. The general aluminum mold system for precast wallboard components in prefabricated buildings is made of aluminum profiles with electrostatic powder spraying, and is realized by matching standardized cutting lengths, assembly methods, mold accessories, and holes. This general aluminum mold system not only has high precision and stability, but also can adapt to different building requirements and design styles, has universality, and solves the problems of low standardization degree, poor universality, and high cost of precast component molds caused by reasons such as the inability to unify the technical standards and building styles of each construction unit, the low standardization degree of precast components, and the lack of unified standards in the design of each mold factory;

[0034] 2. The wavy section of the concrete contact surface makes the cast finished product present the same shape, increasing the friction and bonding force between the precast component and the cast-in-place concrete, which helps to improve the stability and safety of the installation of the precast component and the pouring of the concrete thickness. The joint between the precast component and the cast-in-place concrete formed thereby has a waterproof effect.

[0035] 3. The smooth section of the concrete contact surface can avoid edge chipping. In addition, it can ensure the release of air bubbles during the pouring process, making the surface of the precast component smooth, reducing the repair work after demolding, and improving the appearance quality of the component.

[0036] 4. The thickening design at the corner can significantly enhance the structural strength and rigidity of the aluminum formwork in the high-stress area, reducing the risk of deformation and damage caused by stress concentration and extending the service life of the formwork. This design is particularly important at the corners of the formwork that bear large lateral pressures and can effectively prevent local damage to the formwork.

[0037] 5. Cost-effectiveness: Although the initial investment cost of the aluminum formwork is relatively high, due to its durability and reusability, the actual cost per use is very low. As the number of uses increases, the cost-effectiveness of the aluminum formwork will become more obvious.

[0038] 6. Lightweight design: The lightweight characteristic of the aluminum formwork (with a mass of only 7.6 - 8.5 kg per meter) greatly reduces the construction difficulty and labor intensity. No heavy lifting equipment is required, and a single worker can complete the installation and removal of the formwork, improving the construction efficiency and reducing the project cost.

[0039] 7. High strength and impact resistance: The aluminum formwork can withstand the huge pressure and impact force generated during concrete pouring, reducing the risk of formwork deformation and ensuring the geometric dimension accuracy of the precast component.

[0040] 8. Anti-bulging formwork performance: Through careful design and professional operation of the construction personnel, the aluminum formwork can avoid the problem of bulging formwork during concrete pouring, ensuring the surface flatness and structural integrity of the precast component.

[0041] 9. High recycling rate: The aluminum formwork can be recycled 150 - 200 times, far exceeding the service life of traditional wooden formwork, greatly saving resources and reducing waste generation.

[0042] 10. Sustainability and environmental protection: The scrapped aluminum formwork can be recycled and remelted into new aluminum products, realizing the recycling of resources, meeting the concept of green building and sustainable development. In addition, the use of aluminum formwork meets the national requirements for green building materials, which is conducive to promoting the transformation and upgrading of the entire construction industry.

Detailed implementation manners

[0057] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical methods of the present utility model. However, the present utility model is not limited to these embodiments.

[0058] As Figures 1-12 shown, the present utility model provides a general aluminum formwork system for prefabricated components, including:

[0059] Aluminum formwork profiles 100, which have a concrete contact surface 101 and formwork contact surfaces 102 on both sides. The concrete contact surface 101 has wave segments 1011 and smooth segments 1012 located at both ends of the wave segments 1011. The formwork contact surfaces 102 are set as smooth surfaces, and the corners of the concrete contact surface 101 and the formwork contact surfaces 102 are thickened to form a strengthening part 103. The aluminum formwork profiles 100 are assembled into an aluminum formwork after processing;

[0060] Connecting fittings, through which the connection between the aluminum formwork and the aluminum formwork, between the aluminum formwork and the steel formwork, as well as between the aluminum formwork and the components and tooling is realized.

[0061] The general aluminum formwork system for prefabricated wallboard components in prefabricated buildings is realized by using electrostatic powder-coated aluminum profiles, in combination with standardized cutting lengths, assembly methods, mold fittings, and hole positions. This general aluminum formwork system not only has high precision and stability but also can adapt to different building requirements and design styles.

[0062] By adopting a standardized assembly method, the general aluminum formwork system can be easily maintained and modified, thereby extending its service life. In addition, the electrostatic powder coating treatment method makes the aluminum profiles have excellent anti-mucosal and wear-resistant properties, which can ensure the quality of the wallboard components. The lightweight general aluminum formwork system improves production efficiency. At the same time, due to its reusable characteristics, it is more in line with the concept of energy conservation and environmental protection and will surely be more widely used in the future prefabricated building industry.

[0063] It is worth mentioning that the aluminum formwork profiles 100 in this embodiment have a specific design. Among them,

[0064] The wave segments 1011 of the concrete contact surface 101 make the cast finished product also present this shape, increasing the friction and adhesion between the prefabricated component and the cast-in-place concrete, contributing to improving the stability and safety of the prefabricated component during installation and after casting concrete. The joint between the prefabricated component and the cast-in-place concrete formed thereby has a waterproof effect;

[0065] The smooth segments 1012 of the concrete contact surface 101 can avoid edge chipping. In addition, they can ensure the release of air bubbles during the pouring process, make the surface of the prefabricated component smooth, reduce the repair work after demolding, and improve the appearance quality of the component;

[0066] The thickening design at the corners can significantly enhance the structural strength and rigidity of the aluminum formwork in high-stress areas, reduce the risk of deformation and damage caused by stress concentration, and extend the service life of the formwork. This design is particularly important at the corners of formwork that bear relatively large lateral pressure, effectively preventing local damage to the formwork;

[0067] Since the aluminum formwork is relatively lighter than traditional steel formwork and can be directly carried by production workers, the edges and corners of the aluminum formwork profiles 100 have been rounded.

[0068] In addition, the standardized processing and modular assembly methods of the aluminum formwork profiles 100 improve production efficiency and reduce production costs. The modular design enables the aluminum formwork system to be flexibly combined according to different precast component requirements, realizing the multi-purpose nature of a single set of molds, and reducing mold inventory and replacement costs.

[0069] The use of connecting fittings greatly facilitates the assembly and disassembly of the aluminum formwork system, improving construction efficiency. Standardized connecting fittings can ensure accurate docking between different formworks, improving the stability and precision of the overall structure. In addition, the universality of the connecting fittings enables the aluminum formwork system to be compatible with existing steel formwork systems, expanding the application range and enhancing the flexibility and adaptability of the system.

[0070] This prefabricated precast component standardized aluminum formwork system has many remarkable advantages, which make it one of the key technologies in the process of modern building industrialization. It is particularly suitable for the prefabrication of internal and external wall panels of conventional residential and commercial buildings. Its advantages are as follows:

[0071] 1. Cost-effectiveness: Although the initial investment cost of the aluminum formwork is relatively high, due to its durability and reusability, the actual cost per use is very low. As the number of uses increases, the cost-effectiveness of the aluminum formwork will become more obvious;

[0072] 2. Lightweight design: The lightweight characteristic of the aluminum formwork (with a mass of only 7.6 - 8.5 kg per meter) greatly reduces the construction difficulty and labor intensity. Without heavy lifting equipment, a single worker can complete the installation and removal of the formwork, improving construction efficiency and reducing project costs;

[0073] 3. High strength and impact resistance: The aluminum formwork can withstand the huge pressure and impact force generated during concrete pouring, reducing the risk of formwork deformation and ensuring the geometric dimension accuracy of precast components;

[0074] 4. Anti-bulging formwork performance: Through careful design and professional operation of construction workers, the aluminum formwork can almost completely avoid the problem of formwork bulging during concrete pouring, ensuring the surface flatness and structural integrity of precast components;

[0075] 5. High cycle utilization rate: The aluminum formwork can be recycled 150 - 200 times, far exceeding the service life of traditional wooden formwork, greatly saving resources and reducing waste generation.

[0076] 6. Sustainability and environmental protection: After being scrapped, the aluminum formwork can be recycled and remelted into new aluminum products, realizing the recycling of resources, meeting the concept of green building and sustainable development. Moreover, the use of aluminum formwork meets the national requirements for green building materials, which is conducive to promoting the transformation and upgrading of the entire construction industry.

[0077] To further improve the quality of the aluminum formwork, the aluminum material and surface treatment process are determined as follows:

[0078] Material: 6063 - T5 is adopted, with tensile strength σb ≥ 205 MPa, conditional yield strength σ0.2 ≥ 170 MPa, elongation δ5 ≥ 9%, and hardness (HW): 8 - 12, which can withstand the pressure of concrete pouring and will not show the phenomenon of formwork bulging.

[0079] Surface treatment process: The surface layer is treated by electrostatic powder spraying, which can avoid concrete sticking to the formwork and extend the service life of the formwork. The weight per meter is 6.93 kg for a width of 200 mm and 8.13 kg for a width of 240 mm. The formwork is easy to use and does not require a gantry crane for hoisting. One person can easily complete the installation and removal.

[0080] Preferably, in this embodiment, according to the common sizes of prefabricated interior and exterior wall panels and the single - root length of aluminum materials, the cutting lengths are determined to be 2000 mm / 3000 mm / 4000 mm, and two general assembly methods are determined according to whether the prefabricated precast interior and exterior wall panels have beams:

[0081] 1. For the splicing of wall panels with beams, the lengths of the aluminum formwork on both sides are 2000 mm, the length of the bottom - edge aluminum formwork is 2000 mm / 3000 mm or 4000 mm, and the top - edge is made of steel formwork to adapt to the changes in height and width under the beam. Since the specifications and spacings of the main beam reinforcement bars at the beam ends on both sides are different, for the part exceeding two meters where steel formwork and aluminum formwork are spliced, the applicable situations of the wall panels are as follows:

[0082] (1) 2000 mm on both sides + 2000 mm at the bottom - edge: The height below the beam ≥ 2000 mm, and the width ≤ 1840 mm;

[0083] (2) 2000 mm on both sides + 3000 mm at the bottom - edge: The height below the beam ≥ 2000 mm, and 1840 < width ≤ 2840 mm;

[0084] (3) 2000 mm on both sides + 4000 mm at the bottom - edge: The height below the beam ≥ 2000 mm, and 2840 < width ≤ 3840 mm.

[0085] 2. For the splicing of wall panels without beams, the length of the aluminum formwork on both sides is 3000 mm, and the length of the bottom aluminum formwork is 2000 mm, 3000 mm or 4000 mm to meet the requirements of different wall panel heights and widths. The applicable situations of the wall panels are as follows:

[0086] (1) 3000 mm on both sides + 2000 mm at the bottom: height ≤ 2920 mm, width ≤ 1920 mm;

[0087] (2) 3000 mm on both sides + 3000 mm at the bottom: height ≤ 2920 mm, 1920 < width ≤ 2920 mm;

[0088] (3) 3000 mm on both sides + 4000 mm at the bottom: height ≤ 2920 mm, 2920 < width ≤ 3920 mm.

[0089] For wall panels with and without beams, the specific applicable size ranges of the formwork are given respectively, which helps construction workers select the most suitable formwork combination in actual operation to ensure the dimensional accuracy and structural safety of precast components.

[0090] Determination of standardized connection fittings:

[0091] Preferably, the connection fittings include the aluminum formwork connector 110. The aluminum formwork connector 110 is arranged in an L-shaped structure. The aluminum formwork is connected to the aluminum formwork and the aluminum formwork is connected to the steel formwork respectively through the aluminum formwork connector 110. Specifically, using this L-shaped aluminum formwork connector 110 can not only enhance the overall rigidity of the formwork system, but also simplify the connection and disassembly process. It can be quickly fixed only by standard fasteners such as bolts and pins;

[0092] More importantly, using the L-shaped aluminum formwork connector 110 with a unified specification helps to promote the modularization and standardization of formwork design. Standardized connection fittings mean stronger interchangeability between formworks, reduce the need for customized parts, lower production costs, and simplify inventory management and on-site management at the same time.

[0093] Preferably, the connection fittings also include a threaded blind hole plugging ring 120 and a threaded blind hole fixing ring 121 to meet the requirements of fixing the threaded blind holes on the aluminum formwork profile 100 and the use of a single set of molds for multiple components.

[0094] Preferably, the connection fittings also include a tooling connecting plate 130. The tooling connecting plate 130 is installed on the aluminum formwork profile 100 and is used to meet the connection of various toolings with different uses.

[0095] Preferably, the formwork contact surface 102 is used to fix the aluminum formwork profile 100. The aluminum formwork profile 100 can be fixed by means of bolting through the formwork connection holes 140, fixing with a magnetic box 141 or welding nut-bolt fixing parts 142.

[0096] Preferably, it further includes a tapered rod 150 which is used to connect with the mold table to make template holes for on-site production of precast components, reducing the mold tooling and making the concrete finishing more convenient.

[0097] Determination of standardized hole positions:

[0098] Preferably, different aluminum profile moldings 100 are provided with different standardized hole positions according to different uses, among which,

[0099] The first type of standardized hole positions includes a tooling fixing hole 200 and an aluminum edge connection hole 210;

[0100] The second type of standardized hole positions includes a hanging nail fixing hole 220, a limiting steel bar hole 230, and a reserved steel bar extending hole 240;

[0101] The third type of standardized hole positions includes a blind hole extending hole 250, a threaded blind hole fixing hole 260, a hand hole box connection hole 270, and an aluminum edge connection hole 210;

[0102] The fourth type of standardized hole positions includes a connecting bolt embedment fixing hole 280 and an aluminum edge connection hole 210.

[0103] Furthermore, in the layout of the first type of standardized hole positions, the tooling fixing holes 200 are located on the same straight line and are spaced as required, and the aluminum edge connection holes 210 are located on the same straight line and are spaced at standardized intervals;

[0104] Such a layout facilitates the fixing and adjustment of the template using tooling. At the same time, the dense layout of the aluminum edge connection holes 210 is conducive to the stable connection between templates. The determination of the spacing of the tooling fixing holes 200 can avoid stress concentration and enhance the structural strength of the template.

[0105] In the layout of the second type of standardized hole positions, multiple reserved steel bar extending holes 240 are respectively evenly distributed at positions close to the edge of the aluminum profile molding 100, and the hanging nail fixing hole 220 and the limiting steel bar hole 230 are located on the central axis of the aluminum profile molding 100;

[0106] The evenly spaced reserved steel bar extending holes 240 ensure the uniform distribution of the internal steel bars of the precast components, improving the structural strength and stability of the components. The hole positions on the central axis facilitate symmetric construction and simplify the hoisting and positioning processes.

[0107] In the layout of the third type of standardized hole positions, the aluminum edge connection holes 210 are located at one end of the aluminum profile molding 100, the blind hole extending hole 250 is close to the threaded blind hole fixing hole 260, and multiple hand hole box connection holes 270 are close to each other and are spaced;

[0108] This layout facilitates the installation and fixation of the connecting pieces. The spacing arrangement of the connection holes 270 of the handhole box is convenient for the hand operation of the operator during the construction process, and at the same time ensures the compact connection of the formwork components.

[0109] In the layout of the fourth type of standardized hole positions, the aluminum edge connection holes 210 are located at one end of the aluminum profile 100, and the fixing holes 280 for the embedded parts of the connecting bolts are located on the central axis of the aluminum profile 100;

[0110] The layout of the central axis of the fixing holes 280 for the embedded parts of the connecting bolts ensures the symmetry and balance of the connection between the formworks, and improves the accuracy and stability of the formwork assembly.

[0111] Through the reasonable layout of the above-mentioned standardized hole positions, the following goals can be achieved:

[0112] 1. Improve the mold compatibility: Different types of hole positions can meet the connection, fixation between the formwork components and the docking with external equipment, enabling a set of molds to adapt to the production of multiple precast components, and improving the versatility and production efficiency of the molds;

[0113] 2. Simplify the construction process: The use of standardized hole positions reduces the on-site measurement and positioning work, simplifies the construction process, and improves the construction speed and accuracy;

[0114] 3. Enhance the structural stability: The reasonable layout of the hole positions and the spacing design avoid the problem of excessive local stress of the formwork, and enhance the overall structural stability of the formwork;

[0115] 4. Reduce the production cost: The batch production of standardized hole positions reduces the production cost of a single hole position, and at the same time reduces the cost of mold replacement and maintenance, and reduces the production cost of precast components in the long run.

[0116] In addition, the processing technology is as follows:

[0117] ① Technicians carry out mold design according to the detailed drawings of the precast components in combination with the standardized assembly method, and issue it to the mold processing team after verification;

[0118] ② The mold processing team draws lines according to the design drawings and then uses an aluminum sawing machine for cutting;

[0119] ③ Draw the positioning lines according to the dimensions on the drawings, and mark the hole positions and hole diameters on the positioning lines;

[0120] ④ Use a pistol drill to fix the center point of the hole position to avoid deviation during the drilling process;

[0121] ⑤ Drill holes using a radial drill according to the hole positions drawn on the aluminum mold;

[0122] ⑥ After completion, the technician reinspects the dimensions and hole positions and conducts a trial assembly. After confirmation, it is put into production;

[0123] ⑦ After the first usage project is completed, the molds are cleaned and collected uniformly to establish a mold library, and are used for subsequent projects or reused for other projects after modification.
