Furthermore, existing technologies often inevitably create gaps when connecting walls, affecting not only the aesthetics of the residence but also potentially posing risks of water and air seepage. While some new connection structures have emerged in the market, they generally suffer from structural complexity, inconvenient installation, and high costs, making it difficult to effectively control costs while ensuring connection quality and efficiency.

[0004] Given the limitations of existing technologies, this invention aims to address the issues of stability, safety, ease of construction, and cost control in wall connections for prefabricated housing. This invention focuses on achieving tight and robust connections between walls through innovative connection structure design, while simplifying the construction process and reducing construction costs. Furthermore, this invention strives to improve the sealing and durability of wall connections to extend the lifespan of the housing and reduce subsequent maintenance costs. By solving these technical challenges, this invention not only enhances the overall performance of prefabricated housing but also promotes the further development and widespread adoption of prefabricated building technology.

[0010] Square grooves are designed at two ends of the prefabricated residence wall, which are matched with the side plates of the catching grooves, ensuring the height consistency between the walls and the connecting frame. The top surface of the connecting frame is provided with the reserved opening for pouring concrete, which enhances the integrity and stability of the structure. Concrete is poured through the reserved opening to realize seamless connection between the walls and the connecting frame, which improves the stability and sealing performance of the structure.

[0011] The assembling groove is a square groove, a clamping groove is formed on an inner wall of the assembling groove, the clamping groove is a convex-shaped groove, and the heights of the clamping groove, the assembling groove and the connecting frame are equal.

[0012] The assembling groove is designed as a square groove, and the convex-shaped clamping groove is arranged on the inner wall, which has the same height as the connecting frame and the assembling groove, ensuring the consistency and coordination of the structure. The design of the clamping groove enhances the fitting precision between the assembling groove and the clamping block, and improves the stability after the wall is fixed.

[0014] The assembled plate matches the assembling groove in size, and a "convex"-shaped clamping strip is integrally formed on the surface, and the clamping strip is slidingly connected in the clamping groove to achieve precise fit. The design of the clamping strip provides a flexible connection mode, facilitates the installation and adjustment of the assembled plate, and improves the adaptability and reliability of the connection structure.

[0015] Embedded grooves are provided on the side walls of two parallel side plates of the buckling groove, the height of the embedded groove is equal to the height of the connecting frame, a rubber strip is fixed inside the embedded groove, the thickness of the rubber strip is smaller than the depth of the embedded groove, two sides of the rubber strip are respectively fixed on two parallel side walls of the embedded groove, and the height of the rubber strip is equal to the height of the embedded groove.

[0016] An embedded groove is provided on the side plate of the buckling groove, and a rubber strip is fixed inside the embedded groove. The thickness of the rubber strip is designed to be smaller than the depth of the embedded groove, which provides an appropriate compression space. The design of the rubber strip increases the sealing performance between the wall and the connecting frame, and simultaneously provides a buffering effect, reducing structural stress caused by temperature changes or other factors.

[0017] The surface of the embedded groove is provided with insertion ports, the insertion ports communicate with the assembling groove, a plurality of insertion ports are provided, the plurality of insertion ports are arranged and distributed at equal intervals and equal sizes along the long side of the embedded groove, the clamping blocks are in one-to-one correspondence with the insertion ports, after the clamping blocks are inserted into the insertion ports, the width of each clamping block is larger than the depth of the insertion port.

[0018] The surface of the embedded groove is provided with insertion ports that communicate with the assembling groove, the clamping blocks are in one-to-one correspondence with the insertion ports, and the width of the clamping block is larger than the depth of the insertion port, which ensures the firmness of clamping.

[0019] An end of the clamping block extending toward the assembling groove is provided with an inclined surface, and the inclined surface faces upward;

[0020] The other end of the clamping block is fixed on the surface of the rubber strip. When the assembled plate pushes the clamping block, the clamping block stretches the rubber strip to generate deformation, and the clamping block clamps the rubber strip on one side of the prefabricated residential wall, increasing the friction between the clamping block and the prefabricated residential wall.

[0021] One end of the clamping block is provided with an inclined surface, and the other end is fixed on the surface of the rubber strip. When the assembled plate pushes the clamping block, the rubber strip is stretched to generate deformation, which increases the friction force. The cooperative use of the inclined surface and the rubber strip improves the clamping force of the clamping block on the wall, and enhances the reliability and stability of the connection.

[0022] The top surface of the connecting frame is provided with pre-embedded holes, a plurality of pre-embedded holes are provided, the plurality of pre-embedded holes are arranged in a square array, embedded bars are inserted and fixed inside the pre-embedded holes, and the height of the embedded bars is greater than the height of the connecting frame.

[0023] The top surface of the connecting frame has pre-embedded holes with embedded reinforcing bars fixed inside. The height of the embedded reinforcing bars is greater than the height of the connecting frame, providing connection points for the upper structure. The design of the pre-embedded holes and embedded reinforcing bars facilitates connection with the upper wall, ensuring the continuity and stability of the multi-story prefabricated residential structure.

[0024] The top surface of the prefabricated residential wall is embedded with multiple steel bars, and the top of the steel bars and the top of the implanted steel bars are coplanar.

[0025] The top surface of the prefabricated housing walls is embedded with steel bars, the top of which are coplanar with the embedded reinforcement bars, achieving an effective connection between the wall and the connecting frame. This coplanar design of the steel bars and embedded reinforcement bars strengthens the overall structure and improves the strength and reliability of the connection.

[0026] The assembly method based on the aforementioned prefabricated residential building connection structure includes the following steps:

[0027] S1. After the prefabricated residential walls are assembled on both sides of the connecting frame, and the prefabricated residential walls are clamped and pre-limited by the clamping blocks, in order to fill the gap between the connecting frame and the prefabricated residential walls, concrete or other sealant is poured into the reserved opening. After the reserved opening is filled with sealant, the sealant extends into the gap between the connecting frame and the prefabricated residential walls through the diversion port, thus completing the filling of the gap after the connecting frame and the prefabricated residential walls are assembled.

[0028] S2. After one side of the prefabricated residential wall is pushed into the groove, the assembly panel is pushed into the assembly groove from top to bottom. As the clip slides down the groove, the assembly panel pushes the clamping block along the inclined surface. The clamping block retracts into the socket, and the rubber strip is stretched and deformed when the clamping block moves. The rubber strip is clamped by the clamping block on one side of the prefabricated residential wall, thereby improving the clamping firmness of the clamping block on the prefabricated residential wall. This completes the pre-fixation of the connecting frame and the prefabricated residential wall after assembly.

[0029] The assembly method includes two steps: grouting and pre-fixing. By pouring concrete or other sealant, and through the combined use of assembly panels and clamping blocks, a tight connection is achieved between the wall and the connecting frame. This assembly method not only improves construction efficiency but also ensures the sealing and stability of the wall connection through the grouting and pre-fixing steps, extending the service life of the residence.

[0030] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0031] (1) Simplified structure and convenient installation: The prefabricated housing connection structure proposed in this invention consists of components such as connecting frame, snap groove, assembly groove, clamping block and assembly plate. The structure is simple and easy to process and install.

The whole installation process is quick and convenient, reducing the complexity of construction and making the installation of prefabricated housing walls more convenient and faster, which significantly improves construction efficiency.

[0032] (2) Improved connection firmness and stability: By utilizing the combination of clamping blocks and assembly plates, as well as the tensioning effect of rubber strips, this solution achieves a tight connection between the wall and the connecting frame, greatly enhancing the clamping force between the wall and the connecting frame, thereby improving the stability and firmness of the overall structure and effectively solving the problems of weak connection and structural safety that may occur in traditional connection methods.

[0033] (3) Cost-effectiveness: The structural design and material selection adopted in this scheme aim to reduce production and construction costs while maintaining or improving the performance of the connection structure, making the construction of prefabricated housing more economical and efficient.

[0034] (4) Enhanced sealing and durability: By setting a reserved opening on the top surface of the connecting frame for pouring concrete or other sealant, and by applying rubber strips in the groove, this solution significantly improves the sealing of the wall connection, extends the durability and service life of the structure, and reduces the cost of later maintenance.

[0035] (5) Adaptability and flexibility: The design of this scheme allows for adjustments according to different construction needs and environmental conditions. For example, the integrated molding design of the assembly plate and the clip provides a flexible installation method to adapt to different assembly requirements.

[0036] (6) Convenience of multi-layer structure connection: The design of the pre-embedded holes and implanted bars on the top surface of the connecting frame facilitates the connection with the prefabricated residential wall that needs to be connected to the upper layer, which provides convenience for subsequent construction and ensures the integrity and continuity of the structure.

[0037] (7) Construction quality and aesthetics of the house: By opening a reserved opening on the top surface of the connecting frame and opening an assembly groove on the wall surface that communicates with the reserved opening, concrete or other sealant can be poured into the reserved opening after installation, so as to achieve a seamless connection between the wall and the connecting frame, reduce the gaps at the wall connection, improve the appearance quality and aesthetics of the house, and meet the dual needs of modern houses for aesthetics and practicality.

[0038] In summary, this solution addresses the shortcomings of existing technologies by providing a prefabricated residential connection structure that is simple in structure, easy to install, has a strong connection, is cost-effective, has durable sealing, strong adaptability, facilitates multi-layer connections, and has an aesthetically pleasing appearance. It has significant market application prospects and social benefits. Attached Figure Description
