Description

Technical Field

[0001] This utility model belongs to the field of prefabricated buildings, and in particular relates to a connection structure between a foundation and a modular building. Background Technology

[0002] With the acceleration of construction and increased environmental awareness, the construction industry is shifting towards a more efficient and environmentally friendly approach. Modular construction, as a new type of industrialized building method, is receiving increasing attention due to its ability to improve construction efficiency, shorten construction cycles, and reduce environmental impact. However, existing modular building connection technologies, especially in the connection between the foundation and the modular structure, still present some challenges.

[0003] Currently, the traditional connection between the foundation and the main building structure often uses cast-in-place concrete or steel structure connections. These methods require a large amount of manpower and equipment during on-site construction, are relatively time-consuming, and have a significant impact on the environment. Furthermore, quality control of on-site casting is relatively difficult, which may lead to insufficient connection strength and affect the overall stability of the building.

[0004] In addition, these methods often have certain limitations in the treatment of foundations and cannot adapt to various geological conditions.

[0005] Therefore, there is an urgent need for a new type of connection structure between the foundation and modular building. Utility Model Content

[0006] The purpose of this utility model is to provide a connection structure between the foundation and modular building, which can solve the problems of traditional connection methods, which may lead to unstable connection between modules under long-term load, affecting the overall performance and safety of the building; require a long installation time and a lot of labor during construction, affecting construction efficiency; and are difficult to apply to concrete modules of different sizes and shapes, limiting the flexibility of building design.

[0007] This utility model is implemented as follows: a connection structure between a foundation and a modular building includes a foundation and a modular building. The foundation has embedded reinforcing bars, the lower section of which is embedded in the foundation and the upper section protrudes upward from the top surface of the foundation. The concrete walls of the modular building have embedded a number of spaced-apart pipes, the lower ends of which protrude from the bottom surface of the modular building. The upper sections of the reinforcing bars are inserted into the pipes, and the gap between the reinforcing bars and the inner wall of the pipes is filled with high-strength grout.

[0008] Furthermore, the tube is a metal corrugated pipe.

[0009] Furthermore, the upper end of the pipe is inclined toward the inside of the modular building and protrudes from the inner side of the modular building to serve as a grouting inlet.

[0010] Furthermore, the reinforcing bar has a bent anchor section, which is tied or welded to the reinforcing steel structure in the foundation.

[0011] Furthermore, the length of the bent anchor section is 15 times its diameter.

[0012] Furthermore, the length of the upper section of the insert is 420mm or more, and the length of the upper section of the insert is 900mm or more.

[0013] Furthermore, the distance between two adjacent tubes is between 20-30mm.

[0014] The connection structure between the foundation and modular building provided by this utility model has the following advantages compared with the prior art:

[0015] 1. Improve the stability of building structures: The foundation is a crucial supporting component of a building, and modular buildings require a secure connection to the foundation to ensure the overall structural stability. The connection structure of this invention provides a reliable connection, enhancing the building's resistance to various loads and reducing structural safety hazards caused by weak connections.

[0016] 2. Adapting to the characteristics of modular buildings: The prefabrication and on-site assembly of modular building components necessitates an efficient and convenient connection method to link modules together and with the foundation. This utility model's connection structure allows for rapid on-site construction, reducing construction time and costs while ensuring connection quality, thus meeting the production and construction requirements of modular buildings.

[0017] 3. Enhanced Seismic Resistance: In areas prone to natural disasters such as earthquakes, the seismic resistance of buildings is crucial. The connection structure of this invention can effectively transmit seismic forces, enabling the foundation and modular building to work together, thereby improving the overall seismic resistance of the building and ensuring its safety.

[0018] 4. Improved building durability: A good connection method can reduce the erosion of the connection points by external factors such as moisture and air, extending the service life of the building. The connection structure of this utility model can form a sealed connection interface, reducing the risk of corrosion and damage, and improving the durability of the building.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] Traditional methods of connecting the foundation to the main building require a significant amount of manpower and equipment during on-site construction, are relatively time-consuming, and have a substantial environmental impact. Furthermore, quality control during on-site pouring is relatively difficult, potentially leading to insufficient connection strength and affecting the overall stability of the building.

[0025] To address the aforementioned technical problems, this embodiment provides a connection structure between the foundation and modular building. Please refer to... Figures 1 to 2 The connection structure includes a foundation 1 and a modular building 2. The foundation 1 is pre-embedded with reinforcing bars 3. The lower section of the reinforcing bars 3 is embedded in the foundation 1, and the upper section protrudes upward from the top surface of the foundation 1. Several spaced pipes 4 are pre-embedded in the concrete wall of the modular building 2. The lower end of the pipes 4 is exposed outside the bottom surface of the modular building 2. The upper section of the reinforcing bars 3 is inserted into the pipes 4. The gap between the reinforcing bars 3 and the inner wall of the pipes 4 is filled with high-strength grout.

[0026] Specifically, in this embodiment, the tube 4 is made of corrugated metal, so that the threads on its periphery can increase its contact area with the concrete and form a snap-fit ​​relationship, so that the tube 4 can be firmly embedded in the concrete of the modular building 2.

[0027] The upper end of the pipe 4 is inclined toward the inside of the modular building 2 and is exposed on the inside of the modular building 2 as a grouting inlet 41.

[0028] The reinforcing bar 3 has a bent anchor section, which is tied or welded to the steel reinforcement structure in the foundation 1.

[0029] The construction method for the connection structure between the foundation 1 and the modular building 2 in this embodiment includes the following steps:

[0030] Based on the geological conditions of the foundation, select a suitable foundation type, such as raft foundation, strip foundation, or isolated foundation, and then construct the foundation according to the design requirements.

[0031] Modular building 2 pre-embeds equally spaced pipes 4 in the structural wall according to the structural requirements of the design drawings. The center of the reserved pipe 4 matches the dowel bar 3 at the position of the foundation 1 on site. The deviation range is selected according to the diameter of the pipe 4, and the deviation is controlled to be about 20-30mm.

[0032] The ends of the reinforcing bars 3 reserved at the bottom of the foundation 1 are bent to form a bent anchor section. The length of the bent anchor section is 15 times its diameter. The length of the upper section of the reinforcing bar 3 is more than 420mm and more than 900mm.

[0033] Modular building components are transported to the construction site for connection between the foundation 1 and the modular building 2. During installation, the pre-drilled metal holes in the modular building 2 are aligned with the pre-installed reinforcing bars 3 in the foundation 1, and then the modular building 2 is lowered so that the reinforcing bars 3 are inserted into the metal holes. After the modular building 2 and the foundation 1 are fixed and stabilized using a grouting connection, high-strength grout is injected through the pre-drilled corrugated pipe holes in the inner wall of the modular building structure to form a firm grouting connection.

[0034] Based on the safety level and durability of the building structure, select a relatively high-strength grouting material, prepare it according to the specified ratio and process, and then inject the grouting material into the gap between the reserved pipe 4 and the reinforcing bar 3 in the structural wall through the pre-set grouting pipe to ensure the tightness and strength of the connection.

[0035] In summary, the connection structure between the foundation 1 and the modular building 2 in this embodiment has the following beneficial effects:

[0036] 1. Improve the stability of building structure: The connection structure in this embodiment can provide a reliable connection, enhance the building's resistance to various loads, and reduce structural safety hazards caused by weak connections.

[0037] 2. Adapting to the characteristics of modular buildings: The connection structure in this embodiment can be quickly constructed on-site, reducing construction time and costs, while ensuring connection quality, meeting the production and construction requirements of modular buildings.

[0038] 3. Enhanced seismic performance: The connection structure in this embodiment can effectively transmit seismic forces, enabling the foundation and modular building to work together, thereby improving the overall seismic resistance of the building and ensuring its safety.

[0039] 4. Improve building durability: The connection structure in this embodiment can form a sealed connection interface, reducing the risk of corrosion and damage, and improving the building's durability.
