Compared with traditional concrete cast-in-place buildings, prefabricated buildings are undoubtedly a major improvement. The prefabricated components of prefabricated buildings refer to concrete components prefabricated in factories or on-site according to design specifications. Prefabricated components can be assembled on-site and have a high surface finish. They can achieve the decorative effect of plain concrete, making the structure and the building unified and coordinated. Because prefabricated components have the advantages of fast construction speed, less restrictions on climatic conditions, and can improve building quality, they are widely used in various construction projects.

[0003] During the production and transportation process, some special prefabricated components, such as L-shaped components, require special reinforcement during transportation due to structural reasons. If the open section of the L-shaped prefabricated component is not reinforced, the open section will be easily damaged due to uneven force during transportation. Therefore, we need to provide a high-stability assembled prefabricated component and its installation method. Summary of the Invention

[0004] The object of the present invention is to provide a high-stability assembled prefabricated component and its installation method, and to arrange a reinforcement piece at the angle of the component body to provide auxiliary support for the angle of the component body, thereby enhancing the supporting strength of the component body and avoiding uneven force at the angle of the open L-shaped component body during the production and transportation process, which is easy to cause damage. The reinforcement piece acts directly on the inner side of the L-shaped node, effectively dispersing the stress concentration of the component during the production, lifting and transportation process, reducing the risk of cracks or deformation caused by uneven force, significantly improving the overall stiffness and bearing capacity of the component, and solving the problems raised in the above-mentioned background technology.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 The present invention provides a technical solution: a high-stability prefabricated component, comprising: A component body 1, comprising a vertical plate 11 and a horizontal plate 12 connected to each other, wherein the connection between the vertical plate 11 and the horizontal plate 12 forms an L-shaped node; Reinforcing ribs 2, the reinforcing ribs 2 being arranged inside the component body 1; A reinforcement member 3 is provided inside the connection between the vertical plate 11 and the horizontal plate 12 to enhance the support strength of the component body 1; Specifically, a reinforcement member 3 is provided at the angle of the component body 1 to provide auxiliary support for the angle of the component body 1, thereby enhancing the supporting strength of the component body 1 and avoiding uneven force at the angle of the open L-shaped component body 1 during production and transportation, which is prone to damage. The reinforcement member 3 acts directly on the inner side of the L-shaped node, effectively dispersing the stress concentration of the component during production, lifting and transportation, reducing the risk of cracks or deformation caused by uneven force, and significantly improving the overall stiffness and bearing capacity of the component. During demolding, stacking, or transportation, the exposed corners of L-shaped components are vulnerable to bending or impact due to their hanging position. Reinforcement member 3, formed by a support base 31 and an extension 32, forms a triangular support structure, filling the weak corner area and preventing concrete cracking or rebar displacement. The component body 1 and reinforcement bar 2 are placed in a mold and filled with concrete, thereby securing reinforcement member 3 within the component body 1.

[0020] The reinforcement member 3 includes a support base 31 and an extension portion 32. The support base 31 is located on the inner side of the connection between the vertical plate 11 and the horizontal plate 12. The two extension portions 32 are respectively located on the top of the support base 31 and on one side of the support base 31. The extension portion 32 located on the top of the support base 31 is fixedly connected to the surface of the vertical plate 11, and the extension portion 32 located on the one side of the support base 31 is fixedly connected to the surface of the horizontal plate 12. It is worth noting that there are two extensions 32, one is located on the top of the support base 31 and is installed on the surface of the vertical plate 11, and the other is located on the side of the support base 31 and is installed on the top of the horizontal plate 12. The support base 31 provides auxiliary support for the inner side of the connection between the vertical plate 11 and the horizontal plate 12, and the extension 32 fixes the support base 31. The extension 32 can be adjusted on the support base 31, allowing the position of the extension 32 to be fine-tuned on site to meet the installation requirements of components of different sizes. At the same time, it is easy to disassemble and reuse, reducing construction costs. The two extension parts 32 are respectively fixed on the vertical plate 11 and the horizontal plate 12, and together with the support base 31 form a triangular support structure, which effectively enhances the overall stiffness of the L-shaped node and prevents the component from deforming or cracking when subjected to stress. The support base 31 directly abuts the inner side of the node, filling the suspended weak area at the angle of the traditional L-shaped prefabricated component, reducing stress concentration, and improving bending and shear resistance.

[0021] The extension portion 32 includes an adjustment rod 321, a mounting plate 322, and a nut 323. The nut 323 is welded to the surface of the adjustment rod 321. The portion of the adjustment rod 321 located above the nut 323 is slidably engaged with the mounting plate 322. The portion of the adjustment rod 321 located below the nut 323 is internally threadedly mounted on the support base 31. The mounting plate 322 is fixed to the surface of the component body 1 by bolts. When the fixing plate 322 is loosened, the fixing plate 322 is loosened and the fixing plate 323 is loosened, so that the fixing plate 322 can be easily adjusted.

[0022] Two guide rods 8 are fixedly mounted on the surface of the mounting plate 322, and the surfaces of the two guide rods 8 are slidably mounted inside the support base 31; Among them, the two guide rods 8 and the support base 31 form a double slide rail structure, so that the mounting plate 322 moves in a straight line during the adjustment process to avoid offset or skew, ensuring that the reinforcement 3 is always correctly positioned. The guiding effect can prevent the mounting plate 322 from rotating due to uneven force, improve the adjustment accuracy, and ensure the fit between the extension part 32 and the vertical plate 11 / horizontal plate 12. The sliding cooperation between the guide rod 8 and the support base 31 forms an additional constraint, sharing part of the load at the node, reducing the vibration or deformation of the mounting plate 322 when subjected to force, and improving the overall stability. In addition, coating the surface of the guide rod 8 with an anti-stick liquid can effectively prevent the concrete slurry from solidifying on the surface of the guide rod 8 and prevent the sliding mechanism from getting stuck. The anti-stick coating reduces the friction loss between the guide rod 8 and the concrete, avoids surface rust or scratches, and maintains smoothness for long-term use. It is especially suitable for prefabricated components in humid environments or stacked in the open air, reducing maintenance frequency.

[0023] The sleeve 5 is further included to protect the threaded portion of the adjusting rod 321. The sleeve 5 is installed between the nut 323 and the support base 31, and the sleeve 5 is movably sleeved on the surface of the adjusting rod 321. Furthermore, a protective sleeve 5 is added to the threaded portion of the adjusting rod 321. The sleeve 5 isolates foreign matter such as concrete slurry and dust to prevent the thread groove from being blocked or rusted, thereby ensuring that the adjusting rod 321 can be smoothly screwed for a long time. The sleeve 5 can be quickly disassembled, which is convenient for lubricating or replacing the adjusting rod 321 in the later stage. There is no need to frequently clean concrete residues in the thread, saving maintenance time. The sleeve 5 is a dust-proof sealing sleeve 5 with an elastic telescopic function. It can automatically extend and retract as the adjusting rod 321 is raised and lowered, and always completely wraps the threaded portion, avoiding the protection blind spot caused by the length limitation of the traditional fixed sleeve 5. During the adjustment process, the elasticity of the sleeve 5 ensures that the thread is dust-proof and concrete-proof throughout the entire process, maintaining the smoothness of the adjustment.

[0024] The end of the reinforcing rib 2 adopts a U-shaped exposed structure. The reinforcing rib 2 includes a transverse rib 21 and a vertical rib 22. The transverse rib 21 is embedded in the horizontal plate 12, and the vertical rib 22 is embedded in the vertical plate 11. The adjacent ends of the transverse rib 21 and the vertical rib 22 are fixedly connected. Specifically, the surface of the reinforcement bar 2 is coated with an anti-rust coating, such as epoxy resin, galvanized layer, etc., which effectively isolates moisture, oxygen and corrosive media, prevents the steel bars from rusting in concrete, and significantly extends the service life of the components. It is especially suitable for humid, salt spray or chemical corrosion environments (such as coastal buildings and underground projects), solving the industry problem that traditional steel bars are prone to rust. Ribbed epoxy coatings can also be coated. Ribbed epoxy coatings can optimize the surface roughness of the steel bars, improve the bond strength with concrete, avoid degradation of bonding performance due to rust, ensure that the reinforcement bar 2 and concrete are coordinated in force, and prevent cracks or peeling at the nodes. The coating can play a role in the production, stacking and transportation stages of prefabricated components, prevent the steel bars from rusting due to exposure to moisture before pouring, reduce the loss of steel bar cross-section due to rust, and ensure the realization of the designed bearing capacity; At the same time, the end of the reinforcement bar 2 adopts a U-shaped exposed structure. The U-shaped bending structure greatly increases the anchoring contact area between the steel bar and the adjacent components (such as post-cast concrete or other prefabricated parts), avoiding the pull-out failure problem that is prone to occur in traditional straight bar exposure. The bending part forms a mechanical bite effect, which improves the tensile and shear resistance. It is especially suitable for prefabricated nodes that bear dynamic loads. The U-shaped arc transition can alleviate the stress concentration phenomenon at the end of the steel bar and prevent the concrete from cracking at the node due to local high pressure. Compared with straight bars, the U-shaped structure can transfer the load more evenly to the entire connection area.

[0025] A reserved groove 4 is provided at the bottom of the support base 31 and is located at the angle of the component body 1; Among them, the reserved groove 4 provides a fault-tolerant space for concrete burrs, release agent accumulation or small foreign objects that may remain during the component production process, avoiding the support base 31 from being suspended or tilted due to tiny impurities, and completely eliminating the "point contact" stress concentration problem caused by the loose fitting of the traditional reinforcement 3, so that the load is evenly transmitted to the entire node area. During on-site installation, there is no need to manually clean up the tiny impurities at the angles. The support base 31 can be snapped into place with one click. By avoiding the virtual connection of the support base 31, the reinforcement system and the component are ensured to deform synergistically, which significantly reduces the risk of concrete cracking at the node. The depth of the reserved groove 4 has been mechanically optimized to ensure the slag holding capacity without weakening the supporting strength of the support base 31.

[0026] An assembly seat 6 is fixedly mounted on one side of the vertical plate 11, and an assembly groove 7 is provided on the other side of the vertical plate 11 for use with the assembly seat 6 for plugging and fitting adjacent component bodies 1; Specifically, an assembly seat 6 and a matching assembly groove 7 are respectively provided on both sides of the vertical plate 11 to realize the rapid plug-in installation of adjacent components. The standardized interface design of "protrusion-groove" is adopted to realize blind plug-in docking between components, shorten the installation time of a single node, and have a vertical limit function.

[0027] The ends of the reinforcing ribs 2 penetrate the surface of the component body 1 and extend; Furthermore, the exposed steel bars form a "three-dimensional truss-type" connection network, which increases the tensile strength of adjacent components. The ends of the extended steel bars are pre-coated with a conductive anti-corrosion coating to support quick connection by resistance welding, and are coated with a nano-composite anti-corrosion coating to solve the durability problem of exposed steel bars.

[0028] A method for installing a high-stability prefabricated component comprises the following steps: Step 1: First, adjust the distance between the mounting plate 322 and the support base 31. By rotating the nut 323, the adjusting rod 321 can be driven to rotate, and the surface of the adjusting rod 321 is installed with the internal thread of the support base 31; Step 2: Slide the surface of the adjustment rod 321 inside the mounting plate 322 to control the movement of the mounting plate 322 and adjust the movement of the two mounting plates 322 to ensure a suitable distance; Step 3: After adjusting the distance between the two mounting plates 322, fit the side of the support base 31 to the vertical plate 11 and the bottom of the support base 31 to the horizontal plate 12. Drill holes on the surface of the component body 1 according to the inner hole positions of the mounting plate 322. Insert expansion bolts through the mounting plate 322 and connect them to the holes. Fix the mounting plate 322 to the surface of the component body 1. Step 4: Provide auxiliary support at the angle of the surface of the component body 1 through the reinforcement 3, thereby significantly improving the overall stiffness and bearing capacity of the component.
