Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a prefabricated UHPC structure with internal drainage. Background Technology

[0002] Prefabricated construction involves manufacturing some or all of the building components in a factory, transporting them to the construction site, and assembling them using reliable connection methods. The advantages of this construction method include improved project quality, shorter construction time, reduced labor intensity, and less on-site wet work.

[0003] In existing technologies, due to relatively limited building technology and materials, buildings such as hotels typically use external drainage systems. External drainage systems are a simple and effective drainage method; they do not require complex internal piping systems, are relatively easy to construct, and have low costs. However, with rising living standards, people are increasingly paying attention to the appearance of buildings such as hotels. Traditional frame-type drainage systems typically consist of a frame structure, drainage pipes, drainage holes, and sealing strips. The frame structure, composed of columns and beams, supports the curtain wall panels; the drainage pipes are located on the outside of the frame to drain rainwater from the curtain wall surface; drainage holes are installed on the beams or columns of the frame to allow rainwater to drain smoothly; and sealing strips prevent rainwater from entering the frame's interior. During use, rainwater discharged through the external drainage pipes leaves watermarks on the exterior of the curtain wall, affecting the building's appearance. These marks not only detract from the aesthetics but can also lead to stain accumulation on the curtain wall surface, requiring regular cleaning and increasing operating costs. This hinders the promotion and application of external drainage systems in the building technology field. Utility Model Content

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.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example: Figures 1 to 5As shown, a prefabricated UHPC structure with internal drainage is provided. To ensure the overall stability of the structure, the prefabricated UHPC structure is installed on the main structural body 7, which is a wall or other steel structure. In this embodiment, the prefabricated UHPC structure mainly consists of horizontal joists 1, hangers 2, support bases 3, drainage supports 4, and a UHPC frame 5. The horizontal joists 1 are fixed to the main structural body 7 using expansion bolts or other connectors to ensure stability during installation and use. The horizontal joists 1 are a pair, spaced apart and parallel. The parallel horizontal joists 1 provide additional lateral support, increasing the stability and lateral force resistance of the entire structure. They also distribute the load applied to the structure more evenly, reducing local stress concentration and thus improving the structure's load-bearing capacity. In this embodiment, two parallel horizontal joists 1 are used to meet structural strength requirements and ensure the reliable installation of the support base 3. Two hook-fitting components 2 are provided, each hooked onto one of the two horizontal keels 1 and used to connect to the support base 3. These two components distribute the load across the two horizontal keels 1 more evenly, reducing the stress on individual keels and improving the overall structural stability and load-bearing capacity. Furthermore, the two components provide dual connection points, enhancing the reliability of the connection between the horizontal keels 1 and the support base 3 and improving structural safety. The drainage support component 4 is installed on top of the support base 3 and supports the UHPC frame 5. The drainage support component 4 provides a stable support point for the UHPC frame 5, ensuring it can withstand design loads, including its own weight, wind load, and snow load. The aforementioned drainage support 4 has multiple drainage holes 4-1, which are located inside the UHPC frame 5. The design of the drainage holes 4-1 allows water to drain smoothly through these holes, preventing water from accumulating inside the frame and reducing water erosion and damage to the structural materials. At the same time, the inner drainage holes 4-1 help reduce water from flowing down from the outside of the UHPC frame 5, avoiding water marks on the exterior surface of the building and maintaining the cleanliness and aesthetics of the building's appearance.

[0022] To improve the overall structural rigidity and deformation resistance, in this embodiment, a vertical keel 9 is installed between a pair of the aforementioned horizontal keels 1. The aforementioned hook-and-loop fastener 2 is fixed to the aforementioned horizontal keel 1 via a keel connector 8, which is a long bolt, connecting the aforementioned hook-and-loop fastener 2, the aforementioned horizontal keel 1, and the aforementioned vertical keel 9 into a single unit. This connection method can more effectively transfer loads, enabling the structure to withstand greater loads, including self-weight, wind loads, snow loads, etc. Furthermore, using long bolts as connectors facilitates installation and disassembly, improving construction efficiency. It also facilitates future maintenance and replacement, and improves construction accuracy, ensuring a tight connection between the horizontal keel 1, the hook-and-loop fastener 2, and the vertical keel 9, reducing errors.

[0023] In this embodiment, the aforementioned horizontal keel 1 is a hollow cuboid structure. This hollow cuboid structure reduces the overall weight of the structure while maintaining sufficient strength and rigidity, thus improving the building's economy and ease of construction. The aforementioned hook 2 includes a hook body 2-1, which has a semi-enclosed structure to cover the horizontal keel 1. Compared to ordinary structures, this semi-enclosed structure increases the contact area between the hook body 2-1 and the horizontal keel 1, thereby enhancing the connection strength between the hook 2 and the horizontal keel 1 and ensuring structural stability. To further reduce installation difficulty and increase installation speed, a hook 2-2 is formed on the side of the hook body 2-1 in this embodiment; the aforementioned support base 3 has a hook groove 3-1, and the hook 2-2 is used to hook into the hook groove 3-1 to connect the hook 2 to the support base 3. The form of the hook 2-2 and the hook groove 3-1 makes the connection between the hook 2 and the support base 3 more convenient and faster, without the need for complex installation procedures. The combination of the hanging body 2-1 and the hook 2-2 of the above-mentioned semi-enclosed structure can effectively improve the seismic performance of the overall structure and reduce displacement and deformation.

[0024] In this embodiment, an adjustment hole 2-3 is provided at the aforementioned mounting body 2-1 for the aforementioned keel connector 8 to pass through. The adjustment hole 2-3 is an elongated hole, which allows the keel connector 8 to move within a certain range, thereby allowing for fine adjustment of the relative position between the mounting member 2 and the horizontal keel 1 and vertical keel 9 to accommodate structural bodies 7 and UHPC frames 5 with different spacing, thus meeting installation requirements. In the internal drainage system, by changing the spacing between the structural body 7 and UHPC frame 5, the drainage path and drainage efficiency can be optimized, thereby reducing water flow marks and protecting the building's appearance.

[0025] In this embodiment, the upper and / or lower surfaces of the aforementioned mounting body 2-1 are formed with adjusting teeth 2-4. A toothed pad 10 is added between the aforementioned keel connector 8 and the aforementioned mounting body 2-1, that is, the toothed pad 10 is engaged with the position of the adjusting teeth 2-4. The toothed pad 10 can provide additional support and fixation, enhance the connection stability between the keel connector 8 and the mounting body 2-1, and prevent loosening or displacement caused by external forces. Furthermore, the cooperation between the adjusting hole 2-3 and the adjusting teeth 2-4 can improve construction accuracy, ensure tight connection between various components, and reduce errors during construction.

[0026] In this embodiment, a limiting member 6 is also installed between the aforementioned hook 2 and the aforementioned support base 3. The limiting member 6 is arranged in a "Z" shape, with one end for passing through the hook 2-2 and abutting against the side of the hook body 2-1, and the other end for fitting against the top of the aforementioned support base 3. This ensures the accurate position of the hook 2 on the support base 3, preventing displacement of the hook 2 during installation or use, and ensuring the stability and safety of the structure. The limiting member 6 also prevents the connection between the hook 2 and the support base 3 from loosening due to external forces (such as wind force, earthquake force, etc.), enhancing the overall stability of the structure. Under dynamic loads such as earthquakes, the limiting member 6 can also restrict the movement of the hook 2, reducing structural vibration and deformation, and improving the seismic performance of the structure. The hook 2-2 has a hook connection hole 2-5, and a connector is inserted into the hook connection hole 2-5 for fixing to the limiting member 6, further improving the overall structural stability.

[0027] The support base 3 in this embodiment includes a base body 3-2, two hooks 2-2, and two corresponding mounting slots 3-1. Both mounting slots 3-1 are formed on the side of the base body 3-2. The cooperation of the two mounting slots 3-1 and the two hooks 2-2 ensures a stable connection between the mounting member 2 and the support base 3, preventing structural swaying or displacement due to wind or other external forces. This design effectively improves the load-bearing capacity of the support base 3, enabling it to support the drainage support member 4 above and other possible loads. The top of the base body 3-2 has a mounting groove 3-3 for supporting the drainage support member 4. The bottom of the drainage support member 4 is embedded in the mounting groove 3-3, making installation more convenient and quick, and also facilitating later maintenance and replacement. The design and installation method of the drainage support member 4 helps improve drainage efficiency. Through cooperation with the mounting groove 3-3, the accurate positioning of the drainage support member 4 is ensured, thereby optimizing the drainage path.

[0028] In this embodiment, the drainage support 4 mainly consists of a support mounting part 4-2 and a support part 4-3. The support mounting part 4-2 is installed in the mounting groove 3-3, and the support part 4-3 is integrally formed on the top of the support mounting part 4-2. A drainage hole 4-1 is formed at the support part 4-3. Positioning the drainage hole 4-1 at the support part 4-3 and inside the UHPC frame 5 effectively collects and guides water flow, ensuring smooth drainage and reducing damage to the structure. The location of the drainage hole 4-1 makes the drainage system easier to inspect and maintain, as it is close to the bottom of the UHPC frame 5, facilitating cleaning and inspection for blockages. The support part 4-3 also provides additional support, enhancing the stability of the entire drainage support 4 and ensuring its reliability under load.

[0029] In this embodiment, a frame mounting groove 4-4 is provided on the top of the support part 4-3 for the bottom of the UHPC frame 5 to be embedded. The frame mounting groove 4-4 provides a clear embedding position for the UHPC frame 5, ensuring that the UHPC frame 5 can be accurately installed in the predetermined position, thereby improving the overall alignment accuracy of the structure. Through the frame mounting groove 4-4, the UHPC frame 5 can be installed quickly and easily, simplifying the installation process and saving time and labor.

[0030] In this embodiment, in order to further ensure the stability of the overall structure, a plurality of limiting protrusions 4-5 are formed on the wall surface of the support mounting part 4-2, and the support base 3 has a limiting hole 3-4. A positioning member 11 is inserted into the limiting hole 3-4 to prevent the drainage support 4 from moving upward.

[0031] In this embodiment, the horizontal keel 1, the hanger 2, the support base 3, and the drainage support 4 are all made of extruded aluminum. Aluminum typically has a low density but high strength, which makes the manufactured components both lightweight and capable of bearing sufficient load. Furthermore, aluminum can form a dense alumina film in the natural environment, which protects the aluminum from further corrosion, thereby improving the durability of the components. The corrosion resistance and recyclability of aluminum mean that it can be recycled and reused at the end of its service life, reducing long-term maintenance costs and contributing to improved overall building performance and sustainability.

[0032] This embodiment presents a prefabricated UHPC structure with internal drainage. This prefabricated UHPC structure is ingenious and highly stable. It consists of horizontal keels 1, hooks 2, support bases 3, drainage supports 4, and a UHPC frame 5. The horizontal keels 1 are a pair, spaced apart and parallel. There are two hooks 2, each hooked onto one of the two horizontal keels 1. The support base 3 is connected to the hooks 2. The drainage supports 4 are installed on top of the support base 3 and support the UHPC frame 5. The drainage supports 4 have multiple drainage holes 4-1, which are located inside the UHPC frame 5. This allows the prefabricated UHPC structure to drain water inward, reducing water flow on the facade, thus ensuring the aesthetic appearance of the building and improving the user experience. This facilitates the promotion and application of the aforementioned prefabricated UHPC structure with internal drainage in the field of building construction technology.
