Description

Technical Field

[0001] This utility model relates to the field of light steel modular housing construction technology, and in particular to the foundation pile component of a modular light steel modular housing. Background Technology

[0002] In the field of light steel prefabricated housing construction, it is widely used in temporary buildings, post-disaster resettlement housing, rural residences, and industrial ancillary buildings due to its characteristics such as light weight, high assembly efficiency, excellent space utilization, and strong adaptability to different building scenarios. As the core foundation supporting the structural safety and long-term stability of the entire light steel prefabricated housing, its stability directly determines the load-bearing capacity, anti-settlement performance, and wind and earthquake resistance of the house. It is a key prerequisite for ensuring the structural safety and normal function of the light steel prefabricated housing during long-term use. The foundation pile components of light steel prefabricated housing are core foundation components developed based on the special requirements of light steel prefabricated housing for foundation support. These components fully combine the structural characteristics of light steel prefabricated housing and, through scientific structural design, can effectively achieve a close bond with the foundation soil. At the same time, they are precisely adapted to the assembly construction process of light steel prefabricated housing and can quickly complete a reliable connection with the upper light steel components.

[0003] Traditional light steel prefabricated house foundation pile structure is relatively simple, usually relying on only a single or a few vertical piles for support. For some scenarios with poor geological conditions or high requirements for house stability, its stability is often difficult to meet the needs. Moreover, the connection method between traditional pile base and inclined pile is not convenient and efficient, the installation process is complicated, and it affects the construction progress. Therefore, we propose a modular integrated light steel prefabricated house foundation pile component. Utility Model Content

[0004] The purpose of this utility model is to provide a modular light steel prefabricated house foundation pile component to solve the problem that the traditional light steel prefabricated house foundation pile structure is relatively simple, usually relying on only a single or a few vertical piles for support. For some scenarios with poor geological conditions or high requirements for house stability, its stability is often difficult to meet the requirements. Moreover, the traditional connection method between the pile base and the inclined pile is not convenient and efficient, the installation process is complicated, and it affects the construction progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated integrated light steel modular house foundation pile base component, including a pile base body, a central mounting hole for mounting ground piles is provided in the center of the bottom surface of the pile base body, a plurality of first connecting holes are provided around the central mounting hole on the surface of the pile base body, a plurality of pile sleeves are provided on the periphery of the pile base body, and a plurality of pile sleeves are provided on each of the plurality of pile sleeves.

[0006] As a preferred embodiment, the number of pile sleeves is six, and they are evenly distributed around the periphery of the pile base body.

[0007] As a preferred embodiment, the pile base body is made of metal and has a hollow cavity inside.

[0008] As a preferred embodiment, the pile base body is provided with reinforcing ribs, which are distributed at the connection between the pile base body and the pile sleeve. The surface of the pile base body that contacts the ground pile is provided with anti-slip textures, which are uniformly distributed in strips.

[0009] As a preferred embodiment, the surface of the pile base body and the inner wall of the pile sleeve are both provided with an anti-corrosion coating, which is a multi-layer composite coating.

[0010] As a preferred embodiment, the inner walls of the first and second connecting holes are provided with internal threads for threaded connection with the connector and the pile body.

[0011] The technical effects and advantages of this utility model are as follows: Multiple inclined piles can be easily connected through multiple pile sleeves around the main body of the pile base and the second connecting holes on each pile sleeve. They work together with the central pile column, which can significantly improve the stability of the foundation compared with traditional pile bases that rely on only a single or a few vertical piles. This meets the needs of scenarios with poor geological conditions or high stability requirements. Moreover, the connection method is simple and does not require complicated processes. At the same time, the main body of the pile base is made of metal and has a hollow cavity inside, which reduces its own weight while ensuring structural strength, making it easy to transport and install. The reinforcing ribs at the connection between the pile base and the pile sleeve can further enhance the structural strength and improve the bearing capacity.

[0012] The uniform anti-slip stripes on the contact surface between the pile seat body and the ground pile can increase friction and prevent relative sliding to improve connection reliability.

[0015] 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.

[0016] Please see the appendix Figure 1 - Appendix Figure 4 The integrated light steel prefabricated house foundation pile component includes a pile base body 1. A central installation hole 3 for mounting ground piles is opened in the center of the bottom surface of the pile base body 1. Multiple first connecting holes 4 are opened around the central installation hole 3 on the surface of the pile base body 1. Multiple pile sleeves 2 are set around the periphery of the pile base body 1. Each pile sleeve 2 has a second connecting hole 5. In this structural design, the diameter of the central installation hole 3 is precisely matched with the outer diameter of the ground pile, allowing the central ground pile to be quickly inserted and initially positioned with the pile base body 1 without complicated calibration steps. At the same time, the first connecting holes 4 can be used to firmly lock the pile base body 1 to the bottom frame of the light steel prefabricated house or the top structure of the ground piles through bolts and other connectors. The second connecting holes 5 provide a stable interface for the docking of the pile sleeves 2 and the inclined piles. The dual connection design not only ensures assembly efficiency, but also provides a solid and stable foundation for the subsequent construction of the overall foundation, avoiding installation deviations that may affect structural safety.

[0017] There are six pile sleeves 2, which are evenly distributed around the pile base body 1. The six evenly distributed pile sleeves 2 are arranged radially with the center of the pile base body 1 as the center. The spacing between adjacent pile sleeves 2 is consistent. This layout allows multiple inclined piles to form a symmetrical triangular support system after installation, which evenly distributes the vertical load and soil lateral pressure transmitted by the light steel prefabricated house to the depth of the foundation. Even in complex construction scenarios such as soft soil or windy conditions, it can effectively resist foundation settlement or structural displacement, and further improve the overall stability of the foundation of the light steel prefabricated house.

[0018] The surface of the pile base body 1 and the inner wall of the pile sleeve 2 are both covered with an anti-corrosion coating 7. The anti-corrosion coating 7 is a multi-layer composite coating. The multi-layer composite anti-corrosion coating 7 adopts a composite structure of primer, anti-corrosion topcoat and sealing layer. The primer can enhance the adhesion to the metal surface of the pile base body 1 and the inner wall of the pile sleeve 2. The anti-corrosion topcoat can actively isolate moisture, salt and microorganisms in the soil. The sealing layer further fills the gaps in the coating to form a tight protective barrier without dead corners. This coating design can not only resist the long-term erosion of the underground humid environment, but also adapt to the expansion and contraction of the coating caused by temperature changes, significantly extending the service life of the components.

[0019] Specifically, the foundation pile component of this modular light steel frame house uses multiple pile sleeves 2 set around the main body 1 of the pile base, and a second connecting hole 5 opened on each pile sleeve 2, to easily connect and install with multiple inclined piles. Compared with the traditional foundation pile base that relies on only a single or a few vertical piles for support, the synergistic effect of multiple inclined piles and the central pile column can significantly improve the stability of the foundation. Even in scenarios with poor geological conditions or high requirements for the stability of the house, it can provide reliable support for the light steel frame house, effectively solving the problem that the stability of traditional pile bases is difficult to meet the requirements. At the same time, this connection method is simple to operate and does not require complicated processes, which greatly improves the construction efficiency and improves the situation where the connection and installation process of traditional pile bases and inclined piles is complicated and affects the construction progress.

[0020] Please see the appendix Figure 2 - Appendix Figure 4 The main body 1 of the pile base is made of metal and has a hollow cavity 9 inside. The main body 1 of the pile base is made of high-strength carbon steel or alloy steel, and its mechanical properties can meet the weight bearing requirements of the light steel prefabricated house, avoiding plastic deformation under long-term pressure. The hollow cavity 9 adopts a honeycomb or grid internal support structure, which reduces the weight of the pile base 1 compared with a solid structure without weakening the overall strength of the pile base. This not only reduces the load pressure during transportation, but also allows construction personnel to manually handle and install it without large hoisting equipment, greatly improving on-site construction efficiency.

[0021] The pile base body 1 is provided with reinforcing ribs 6, which are distributed at the connection between the pile base body 1 and the pile sleeve 2. The surface of the pile base body 1 in contact with the ground pile column is provided with anti-slip textures 8, which are evenly distributed in strips. The reinforcing ribs 6 at the connection between the pile base body 1 and the pile sleeve 2 are integrally cast to form a seamless connection with the two, which can evenly distribute the inclined pile load transmitted by the pile sleeve 2 to the entire pile base body 1, avoiding cracks or loosening at the connection due to stress concentration. At the same time, the anti-slip textures 8 on the contact surface between the pile base body 1 and the ground pile column are evenly distributed in parallel strips, which will not damage the flatness of the contact surface, but can greatly increase the friction coefficient, effectively preventing the pile base body 1 from rotating or sliding on the ground pile column, and ensuring the structural stability after assembly.

[0022] The inner walls of the first connecting hole 4 and the second connecting hole 5 are provided with internal threads for threaded connection with the connector and the pile body. The internal threads of the inner walls of the first connecting hole 4 and the second connecting hole 5 adopt a fine thread design, and the thread accuracy meets the national standard. It can achieve tight meshing with bolts, screws and other connectors of the same specification to avoid loosening after connection. This internal thread design not only allows for precise installation with conventional tools such as wrenches during construction, but also eliminates the need for complex processes such as welding.

[0023] Specifically, the pile base body 1 is made of metal and has a hollow cavity 9 inside. While ensuring structural strength, it reduces the weight of the component itself, making it easier to transport and install. The reinforcing ribs 6 distributed on the pile base body 1 at the connection with the pile sleeve 2 further enhance the structural strength of the pile base body 1, reduce the possibility of deformation when the pile base is subjected to loads such as building weight and soil pressure, and improve the overall load-bearing capacity. The anti-slip texture 8 with strips evenly distributed on the contact surface between the pile base body 1 and the ground pile increases the friction during contact, prevents relative sliding between the pile base and the ground pile, and further improves the reliability of the connection. The multi-layer composite anti-corrosion coating 7 on the surface of the pile base body 1 and the inner wall of the pile sleeve 2 can effectively resist the corrosion of environmental factors such as soil, extend the service life of the component, and enable it to better adapt to different soil and environmental conditions.

[0024] The working principle of this utility model is as follows: This utility model is a prefabricated integrated light steel modular house foundation pile seat component. First, the pre-prepared central ground pile is driven into the designated position of the foundation to be constructed. Then, using the central mounting hole 3 opened in the middle of the bottom surface of the pile seat body 1, the pile seat body 1 is precisely fitted onto the fixed central ground pile. At this time, the anti-slip texture 8 evenly distributed in strips on the contact surface between the pile seat body 1 and the ground pile increases the contact friction between the two and prevents relative sliding, thus initially ensuring the installation stability of the pile seat body 1. Next, using the multiple first connecting holes 4 opened around the central mounting hole 3 on the surface of the pile seat body 1 with internal threads on the inner wall, the pile seat body 1 is further fixed to the central ground pile or the relevant structure at the bottom of the light steel modular house through the appropriate threaded connectors, strengthening the overall connection reliability. After that, six piles evenly arranged around the perimeter of the pile seat body 1 are... In step 2, multiple inclined piles are aligned with the second connecting holes 5 on each pile sleeve 2. Threaded connectors are used to achieve a stable connection between the inclined piles and the pile sleeve 2. The inclined piles are then driven into the foundation, allowing multiple inclined piles to work synergistically with the central pile column, significantly improving the stability of the foundation and meeting the requirements of different geological conditions and high stability. The entire connection process does not require complex technology, effectively improving construction efficiency. During this process, the pile base body 1 is made of metal and has an internal hollow cavity 9, which reduces its weight while ensuring structural strength, facilitating transportation and installation. The reinforcing ribs 6 at the connection between the pile base body 1 and the pile sleeve 2 further enhance the structural strength, reduce deformation under load, and improve the bearing capacity. The multi-layer composite anti-corrosion coating 7 on the surface of the pile base body 1 and the inner wall of the pile sleeve 2 can resist environmental corrosion such as soil during subsequent use, extending the service life of the components. This completes the entire process.
