Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, specifically a prefabricated cavity component. Background Technology

[0002] In the fields of modern construction engineering and industrial equipment manufacturing, precast components are being used more and more widely, offering numerous advantages such as high construction efficiency and stable quality. However, existing precast components still present many problems that urgently need to be addressed in practical applications.

[0003] Existing technologies have the following defects or problems: In some large-scale construction projects, due to the weak splicing of prefabricated components, loosening and cracking may occur at the splices during subsequent construction or use. This not only affects the safety of the overall structure but may also lead to rework, increasing construction and time costs. Furthermore, some prefabricated components have unreasonable designs or inappropriate materials for their insulation and wear-resistant layers. Regarding insulation, some prefabricated components have poor insulation performance, resulting in significant heat loss and increased energy consumption in cold regions. Regarding wear resistance, when prefabricated components are used in environments with high surface wear requirements, such as industrial plant floors and logistics warehouses, their surfaces are prone to wear and peeling, affecting the service life and appearance quality of the prefabricated components.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a prefabricated cavity component, which solves the existing problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated cavity component, comprising a body, wherein splicing components are provided on the outer periphery of the body;

[0007] The splicing component includes a protrusion, with protrusions fixedly connected to all four sides of the top of the protrusion. Threaded holes are provided on the outer periphery of both the protrusion and the body. Mounting grooves are provided on all four sides of the bottom of the protrusion, and the mounting grooves match the protrusions. Screws can be threadedly connected to the outer periphery of the threaded holes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figure 1 , Figure 2 and Figure 3 In this embodiment: a prefabricated cavity component includes a body 1 with splicing components disposed on the outer periphery of the body 1;

[0025] The splicing component includes a protrusion 5. The top four sides of the protrusion 5 are fixedly connected with protrusion 5. The outer periphery of both the protrusion 5 and the body 1 is provided with threaded holes 7. The bottom four sides of the protrusion 5 are provided with mounting grooves 9. The mounting grooves 9 match the protrusion 5. Screws can be threadedly connected to the outer periphery of the threaded holes 7. A connecting groove 6 is provided on one side wall of the body 1. A connecting block 8 is fixedly connected to the side wall of the body 1 away from the connecting groove 6. The connecting block 8 matches the connecting groove 6.

[0026] Specifically, the connecting block 8 of one body 1 is aligned and inserted into the connecting groove 6 of another body 1 to complete the initial positioning, allowing the two horizontal components to quickly reach the correct splicing position. Then, using the matching structure of the protrusion 5 and the mounting groove 9, the splicing position is finely adjusted to allow the two vertical components to be spliced. Finally, screws are screwed into the threaded holes 7 on the outer circumference of the protrusion 5 and body 1, and the tightening force generated by the threaded connection firmly fixes the multiple bodies 1 together. This splicing method greatly enhances the stability of the splice, effectively avoiding loosening and cracking at the splice during subsequent construction or use, ensuring the safety of the overall structure.

[0027] refer to Figure 1 , Figure 3 and Figure 4In this embodiment, the outer wall of the main body 1 is a wear-resistant layer 10, and the inner side of the wear-resistant layer 10 is provided with a heat insulation layer 11. The wear-resistant layer 10 is made of diamond wear-resistant material, and the heat insulation layer 11 is made of glass wool material. The middle part of the main body 1 is a cavity design. The four corners of the main body 1 are provided with sliding grooves 12. The main body 1 is slidably connected with reinforcing plates 2. The reinforcing plates 2 are cross-shaped. The main body 1 is filled with multiple evenly distributed reinforcing ribs 4. The main body 1 is provided with multiple evenly distributed connecting holes 3.

[0028] Specifically, the wear-resistant layer 10 on the outer wall of the main body 1 is made of corundum wear-resistant material. Corundum has high hardness and strong wear resistance. When the prefabricated cavity component is used in environments prone to friction, such as industrial plant floors and logistics warehouses, the wear-resistant layer 10 can withstand frequent friction, protecting the main body 1 from easy wear, thereby extending the service life of the component and maintaining its appearance quality. The insulation layer 11 is made of glass wool, which has a low thermal conductivity and slow heat transfer. When used in cold regions, whether in buildings or industrial equipment, the insulation layer 11 can effectively prevent heat loss from the inside to the outside, reduce energy consumption, and improve the insulation performance of buildings or equipment. The middle part of the main body 1 is designed as a cavity, which reduces its own weight without significantly reducing its load-bearing capacity, achieving rational use of materials and reducing transportation and installation difficulties. The sliding grooves 12 at the four corners inside the main body 1 are slidably connected to the cross-shaped reinforcing plates 2. When the component is subjected to external force, the stress is conducted inside the component. At this point, the cross-shaped reinforcing plates 2 will slide and adjust within the grooves 12 according to the stress distribution, dispersing concentrated stress and enhancing the overall structural strength of the component. Furthermore, the uniformly poured reinforcing ribs 4 inside the main body 1 act as a reinforced skeleton, further improving the component's strength and stability, enabling the precast cavity component to adapt to various complex stress conditions. The connecting holes 3 facilitate its connection with other components. In actual engineering, depending on different installation requirements, bolts, pins, and other connectors can be used through the connecting holes 3 to connect the precast cavity component with other related components.

[0029] The working principle and usage process of this utility model are as follows: Align the connecting block 8 of one body 1 with and insert it into the connecting groove 6 of another body 1 to complete the initial positioning, allowing the two horizontal components to quickly reach the correct splicing position. Then, using the matching structure of the protrusion 5 and the mounting groove 9, the splicing position is finely adjusted to allow the two vertical components to be spliced. Finally, screws are screwed into the threaded holes 7 on the outer periphery of the protrusion 5 and body 1, and the tightening force generated by the threaded connection firmly fixes multiple bodies 1 together. This splicing method greatly enhances the stability of the splice, effectively avoiding loosening and cracking at the splice during subsequent construction or use, ensuring the safety of the overall structure. The wear-resistant layer 10 on the outer wall of the body 1 is made of corundum wear-resistant material. Corundum has high hardness and strong wear resistance. When the prefabricated cavity components are used in environments prone to friction, such as industrial plant floors and logistics warehouses, the wear-resistant layer 10 can withstand frequent friction, protecting the body 1 from easy wear, thereby extending the service life of the components and maintaining the appearance quality. The insulation layer 11 is made of glass wool, which has a low thermal conductivity and slow heat transfer. In cold regions, whether used in buildings or industrial equipment, the insulation layer 11 effectively prevents heat loss from the interior to the exterior, reducing energy consumption and improving the insulation performance of buildings or equipment. The central part of the main body 1 is designed as a cavity, reducing its weight without significantly reducing its load-bearing capacity, achieving rational material utilization and reducing transportation and installation difficulties. The sliding grooves 12 at the four corners of the main body 1 are slidably connected to the cross-shaped reinforcing plates 2. When the component is subjected to external force, the stress is conducted within the component. At this time, the cross-shaped reinforcing plates 2 will slide and adjust within the sliding grooves 12 according to the stress distribution, dispersing concentrated stress and enhancing the overall structural strength of the component. Furthermore, the uniformly poured reinforcing ribs 4 inside the main body 1 act like a reinforced skeleton, further improving the strength and stability of the component, enabling the prefabricated hollow component to adapt to various complex stress conditions. The connecting holes 3 facilitate its connection with other components. In actual engineering projects, depending on different installation requirements, prefabricated cavity components can be connected to other related components through connecting holes 3 using bolts, pins, and other connectors.
