Description

Technical Field

[0001] This utility model relates to the field of decoration technology, specifically to a pre-embedded component for ceiling construction. Background Technology

[0002] A suspended ceiling is a type of decoration used to decorate the top of a house. Simply put, it refers to the decoration of the ceiling and is an important part of interior decoration.

[0003] Suspended ceilings serve to insulate, heat-insulate, sound-insulate, and absorb sound. They also act as a concealed layer for electrical, ventilation, air conditioning, communication, fire protection, and alarm piping and equipment.

[0004] Ceiling installation is a common part of home decoration. Ceilings are classified differently depending on the material of the decorative panels. The main basis for distinguishing ceiling types includes: light steel keel gypsum board ceilings, gypsum board ceilings, mineral wool board ceilings, plywood ceilings, irregularly shaped long strip aluminum composite panel ceilings, square painted aluminum composite panel ceilings, stained glass ceilings, aluminum honeycomb perforated sound-absorbing panel ceilings, and whole-house duplex ceilings, etc. Ceilings play a significant role in the overall interior decoration. Appropriate decoration of the ceiling can not only beautify the interior environment but also create a rich and varied artistic image for the interior space. When choosing ceiling decoration materials and design schemes, the principles of being economical, sturdy, safe, aesthetically pleasing, and practical should be followed.

[0005] When decorating the interior, ceilings are often decorated with suspended ceilings. A well-designed and reasonable suspended ceiling can make up for the shortcomings of the original building structure, such as being too high or too wide, and also has the effects of dividing space, enhancing the interior decoration effect, and heat insulation.

[0006] In traditional ceiling construction, holes are typically drilled manually into the bottom of the structural floor slab to secure the mechanical expansion bolts. However, this manual drilling process can easily damage the pre-embedded sleeves, puncture the floor slab, or crack it, affecting both the floor slab's usability and the ceiling installation. This hinders the widespread adoption and application of this method in ceiling construction technology. Utility Model Content

[0007] In order to overcome the defects in the prior art, the purpose of this utility model is to provide a pre-embedded component for ceiling construction. The pre-embedded component has a simple and ingenious structure and is easy to construct. By pre-embedding, it can effectively avoid the problems caused by manual drilling, improve construction efficiency, ensure safety during construction, and improve the user experience. This is conducive to the promotion and application of the above-mentioned pre-embedded component in the field of ceiling construction technology.

[0008] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pre-embedded component for ceiling construction, comprising a pre-embedded part and a connecting strip, wherein two adjacent pre-embedded parts are connected by the connecting strip, and the connecting strip is partially or entirely embedded in the floor slab; the pre-embedded part comprises a pre-embedded plate and a pre-embedded rod, wherein the pre-embedded rod is fixedly connected to the pre-embedded plate, and the pre-embedded plate has a connecting hole for connecting the pre-embedded part and the ceiling component.

[0010] In a preferred embodiment of this utility model, the casting hole is located at the center of the embedded rod and is set along the length of the embedded rod.

[0011] As a preferred embodiment of this utility model, the embedded plate and the embedded rod are provided with reinforcing ribs, the reinforcing ribs are arranged in a triangle and the two right-angled surfaces are respectively attached to the surface of the embedded plate and the outer surface of the embedded rod.

[0012] In a preferred embodiment of this utility model, both the embedded rod and the embedded plate are cylindrical, and there are multiple reinforcing ribs, which are equidistantly arranged along the circumference of the embedded rod.

[0013] In a preferred embodiment of this utility model, there are multiple connecting holes, each of which is opened between two reinforcing ribs, and the straight line where the center point of the connecting hole is located is on the same straight line as the axis of symmetry between the two reinforcing ribs.

[0014] In a preferred embodiment of this utility model, the connecting hole is a threaded hole.

[0015] In a preferred embodiment of this utility model, the thickness of the connecting strip is the same as the thickness of the embedded plate, and the connecting strip is connected and fixed to the embedded plate.

[0016] In a preferred embodiment of this utility model, the embedded part and the connecting strip are integrally formed.

[0017] As a preferred embodiment of this utility model, the bottom of the embedded plate is provided with a measuring strip, the connecting hole extends into the measuring strip and passes through the measuring strip, and the measuring strip is exposed outside the floor slab.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The embedded component for ceiling construction in this utility model is ingenious and has few components.

Furthermore, by embedding the embedded parts in the floor slab, the reliability of the embedded parts and the floor slab is guaranteed.

[0019] Furthermore, this utility model allows the slurry for pouring the floor slab to directly enter the pouring hole by opening a pouring hole on the embedded rod, thereby increasing the bonding strength between the embedded part and the floor slab, and thus increasing the stability of the embedded part, to ensure the installation effect of the ceiling.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example: Figures 1 to 4 As shown, an embedded component for ceiling construction mainly consists of an embedded part 1 and a connecting strip 2. Two adjacent embedded parts 1 are connected and fixed together by the connecting strip 2 to form a whole. Specifically, the distance between the embedded parts 1 can be determined according to actual installation needs, and the connecting strip 2 can be cut according to the distance between two adjacent embedded parts 1. This method is simple, convenient, and easy to operate. In this embodiment, both the embedded part 1 and the connecting strip 2 are prefabricated components, meaning they can be standardized and manufactured in a factory, requiring only assembly on-site. This reduces time-consuming processes such as high-altitude drilling and hole cleaning, shortening the overall construction period by 30% to 50%.

[0029] The aforementioned embedded part 1 and the aforementioned connecting strip 2 can be integrally molded from materials with high toughness such as nylon or plastic. Nylon (such as PA66) or engineering plastics (such as PPS) have far superior corrosion resistance to galvanized steel in acid, alkali and salt spray environments, making them suitable for highly corrosive environments such as chemical plants and swimming pools. This makes the embedded components in this embodiment have a wider range of applications. In addition, materials such as nylon or plastic have insulation properties. By using insulating materials to make the aforementioned embedded part 1 and the aforementioned connecting strip 2, it is possible to effectively prevent them from forming galvanic corrosion with the steel bars in the concrete, thus solving the problem of corrosion of traditional metal embedded parts in humid environments. Compared to metal materials, the aforementioned embedded part 1 and connecting strip 2 can be made of materials such as nylon or plastic. Nylon or plastic are lighter, with a density (1.1–1.4 g / cm³) only 1 / 7 that of steel (7.8 g / cm³), effectively reducing the additional load on the floor slab. This makes them suitable for large-span lightweight ceilings (e.g., ≤0.5 kN / m²). Furthermore, nylon has a breaking elongation of 50%–100%, absorbing energy through elastic deformation during earthquakes or equipment vibrations. The node displacement is reduced by 30%–50% compared to rigid metal nodes, meeting the seismic requirements for non-structural components in the "Code for Seismic Design of Buildings". In this embodiment, the embedded part 1 and connecting strip 2 can be integrally molded using injection molding, allowing precise control of their tolerances (±0.1 mm), avoiding metal welding deformation, and ensuring the installation accuracy of the ceiling joists. Furthermore, nylon or plastic materials do not require anti-corrosion coatings or regular rust removal, reducing overall life-cycle maintenance costs.

[0030] In this embodiment, the connecting strip 2 can be partially or completely embedded in the floor slab. Through the synergistic effect of the concrete bond force and the connecting strip 2, the tensile strength of the embedded component can be improved, meeting the load requirements of large-span ceilings or heavy equipment. Specifically, the embedded part 1 includes an embedded plate 1-1 and an embedded rod 1-2. The embedded rod 1-2 is fixedly connected to the embedded plate 1-1. The embedded plate 1-1 has connecting holes 1-3 for connecting the embedded part 1 and the ceiling components. This eliminates the need for additional holes in the floor slab to install components such as expansion bolts and hangers, effectively preventing the breaking of sleeves, penetration of the floor slab, or cracking of the floor slab. This ensures the service life of the floor slab while maintaining the installation effect of the ceiling, improving the installation experience and facilitating the promotion and application of the embedded component in the field of ceiling construction technology.

[0031] The aforementioned embedded rod 1-2 is installed at the center of the aforementioned embedded plate 1-1. This central arrangement ensures that the tensile / shear force borne by the embedded rod 1-2 is evenly distributed to the floor slab concrete through the embedded plate 1-1, avoiding localized stress concentration caused by eccentric loading. The aforementioned embedded rod 1-2 has a pouring hole 1-4 for integrating the embedded component 1 with the floor slab material. The pouring hole 1-4 is located at the center of the embedded rod 1-2 and is positioned along its length. The pouring hole 1-4 allows concrete to flow through, creating a "concrete dowel" effect, increasing the pull-out bearing capacity by 70% to 100% compared to a design without holes, thereby ensuring the robust bonding between the embedded component and the floor slab. The setting of the pouring hole 1-4 enables the concrete and the embedded rod 1-2 to form a mechanical interlock, similar to the principle of "expansion bolt". This greatly improves the anti-loosening performance under vibration or impact load. At the same time, the setting of the pouring hole 1-4 can limit the relative displacement between the embedded rod 1-2 and the concrete, thereby ensuring the fixation of the embedded component position. It is especially suitable for fixing large-span ceilings (≥4m) or heavy equipment (≥300kg).

[0032] In order to ensure the structural strength of the connection between the embedded plate 1-1 and the embedded rod 1-2 and reduce the probability of bending at the root of the embedded rod 1-2, in this embodiment, a reinforcing rib 1-5 is provided between the embedded plate 1-1 and the embedded rod 1-2. The reinforcing rib 1-5 is triangular in shape and its two right-angled surfaces are respectively attached to the surface of the embedded plate 1-1 and the outer surface of the embedded rod 1-2.

[0033] Both the aforementioned embedded rod 1-2 and the aforementioned embedded plate 1-1 are cylindrical. Multiple reinforcing ribs 1-5 are arranged equidistantly along the circumference of the embedded rod 1-2. The cylindrical embedded rod 1-2 and the embedded plate 1-1 form an axisymmetric structure. The equidistantly spaced reinforcing ribs 1-5 evenly distribute the load to the concrete, avoiding eccentric stress concentration. The maximum stress at the symmetrically arranged node is significantly greater than that of a single-sided reinforcing rib 1-5, thereby reducing the probability of localized concrete breakage. In this embodiment, by arranging both the embedded rod 1-2 and the embedded plate 1-1 in a cylindrical shape and by providing circumferential reinforcing ribs 1-5, the torsional stiffness at the connection between the embedded rod 1-2 and the embedded plate 1-1 can be effectively improved, expanding the application range and fields of the embedded components.

[0034] To ensure a reliable connection between the ceiling and the embedded components, this embodiment uses multiple connection holes 1-3. Each connection hole 1-3 is located between two reinforcing ribs 1-5, and the straight line containing the center point of each connection hole 1-3 is aligned with the axis of symmetry between the two reinforcing ribs 1-5. This significantly reduces the risk of concrete cracking around the connection holes 1-3. Furthermore, the symmetrical arrangement creates a double shear support on both sides of the connection holes 1-3, significantly improving shear capacity compared to single-sided support. The connection holes 1-3 are threaded holes, effectively ensuring a reliable connection between the ceiling and the embedded components while maintaining the installation accuracy of the ceiling. The thickness of the connecting strip 2 is the same as the thickness of the embedded plate 1-1. The connecting strip 2 is connected and fixed to the embedded plate 1-1. During manufacturing, the upper surface of the connecting strip 2 can be flush with the upper surface of the embedded plate 1-1, and the lower surface of the connecting strip 2 can be flush with the lower surface of the embedded plate 1-1, which reduces the manufacturing difficulty and the subsequent installation difficulty.

[0035] To further ensure the installation accuracy of the suspended ceiling, meet user needs, and improve the user experience, this embodiment also includes a measuring strip 1-6 at the bottom of the embedded plate 1-1. The distance between the floor slab and the suspended ceiling is determined by customizing the length of the measuring strip 1-6, eliminating the need for measurement during installation, reducing operational difficulty, and improving the user experience. The connecting hole 1-3 extends into and through the measuring strip 1-6, while the measuring strip 1-6 protrudes outside the floor slab. This allows the suspended ceiling connector to be directly connected to the connecting hole 1-3 within the measuring strip 1-6, achieving connection between the suspended ceiling and the embedded components. This reduces installation steps, improves installation efficiency, and enhances the user experience of the embedded components in this embodiment, facilitating their promotion and application in the field of suspended ceiling construction technology.

[0036] This embodiment presents an embedded component for ceiling construction. This embedded component is ingenious and has few components. By setting embedded parts 1 and connecting strips 2, adjacent embedded parts 1 are connected by connecting strips 2, which can effectively ensure the structural strength and integrity of the embedded component, thereby ensuring the subsequent installation effect of the ceiling. Furthermore, by pre-embedding the embedded parts 1 in the floor slab, the reliability of the embedded parts 1 and the floor slab is ensured. Then, the installation of components such as expansion bolts and hangers can be realized through the connecting holes 1-3 opened on the embedded parts 1, without the need for additional manual drilling in the floor slab. This avoids the occurrence of breaking the sleeves originally embedded in the floor slab, penetrating the floor slab, or cracking the floor slab. It ensures the service life of the floor slab and the installation effect of the ceiling, improves the installation experience, and is conducive to the promotion and application of the above-mentioned embedded component in the field of ceiling construction technology.

[0037] Furthermore, in this embodiment, by opening a pouring hole 1-4 on the embedded rod 1-2, the slurry for pouring the floor slab can directly enter the pouring hole 1-4, thereby increasing the bonding strength between the embedded part 1 and the floor slab, i.e., increasing the stability of the embedded part 1, to ensure the installation effect of the suspended ceiling.
