Technical Field
[0001] The present invention relates to the field of prefabricated buildings, and particularly to a green and sustainable full-module prefabricated building structure. Background Art
[0002] In the construction industry, with the deepening of the concept of sustainable development and the continuous improvement of the requirements for construction efficiency and quality, green and sustainable building structures that are convenient for assembly have become the focus of research; Traditional building structures have many drawbacks in terms of floor connection. On the one hand, the on-site construction connection methods are often cumbersome, requiring a large amount of manpower, material resources, and time, resulting in a long construction period and high costs, which do not meet the current market demand for rapid construction. On the other hand, most traditional connection methods use exposed connections, which not only affect the overall aesthetics of the building appearance, but also have relatively poor connection strength during long-term use, affecting the safety and stability of the building structure. Therefore, how to solve the above problems needs to be considered. Summary of the Invention
[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a green and sustainable full-module prefabricated building structure. In actual use, this structure can conveniently perform prefabricated connection between two floors, and the connection uses a hidden connection method. By using this method, the aesthetics after connection can be increased, and in addition, the strength after overall assembly can be ensured.
[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions: A green and sustainable full-module prefabricated building structure, including two floor main bodies. A through groove is provided through the front and back on each floor main body. Rectangular grooves are opened on the opposite sides of the two through grooves. Each pair of cooperating through grooves and rectangular grooves together form an I-shaped groove. An I-shaped strip that can slide back and forth is arranged in the I-shaped groove; a limiting mechanism for limiting the I-shaped strip and the two floor main bodies. The limiting mechanism includes a rectangular cavity opened in the I-shaped strip. Strip-shaped openings are opened on the left and right inner walls of the rectangular cavity. Two sliders are slidably connected in the rectangular cavity. Plug strips are fixedly connected to the opposite sides of the two sliders. The other side of each plug strip penetrates through the corresponding strip-shaped opening. Limiting grooves are opened on the inner side walls of each through groove. The other end of each plug strip extends into the corresponding limiting groove; a driving mechanism for driving the two sliders to move.
[0005] Preferably, rubber strips are fixedly connected to the opposite sides of the two plug strips.
[0006] Preferably, it further includes a plurality of support strips. A plurality of rectangular grooves are opened at the lower end of each floor main body. Each support strip penetrates through the corresponding rectangular groove.
[0007] Preferably, the driving mechanism includes a bidirectional threaded rod rotatably connected between the left and right inner walls of the rectangular cavity. Both threaded ends of the bidirectional threaded rod penetrate through the corresponding sliders and are threadedly connected.
[0008] Preferably, the threaded directions of the two threaded ends of the bidirectional threaded rod are opposite.
[0009] Preferably, a first rotating shaft is rotatably connected to the front side wall of the rectangular cavity. A second bevel gear is fixedly connected to the rear end of the first rotating shaft. A first bevel gear is installed on the bidirectional threaded rod. The first bevel gear meshes with the second bevel gear.
[0010] Preferably, an operation groove is formed on the front side of the I-shaped bar. The front end of the first rotating shaft extends into the operation groove and is fixedly connected to a second rotating shaft. A rectangular block is fixedly connected to the front side of the second rotating shaft. A rectangular slot is formed on the front side of the rectangular block. A rectangular insertion block that can slide back and forth is arranged in the rectangular slot. The front side of the rectangular insertion block is elastically connected to the rear inner wall of the rectangular slot through a spring. The front side of the rectangular insertion block penetrates through the notch of the rectangular slot and is fixedly connected to a rotating disk. A cross slot is formed on the front side of the rotating disk. A limiting hole is formed through the eccentric part of the rotating disk in the front-rear direction. A connecting bar is fixedly connected to the right inner wall of the operation groove. A limiting rod is fixedly connected to the rear side of the connecting bar. The rear end of the limiting rod penetrates through the corresponding limiting hole and is slidably connected. A cylindrical groove is formed on the rear side wall of the rectangular slot. A piston block that can slide back and forth is arranged in the cylindrical groove. A piston rod is fixedly connected to the front side of the piston block. The front end of the piston rod is fixedly connected to the rear side of the rectangular insertion block. A thin hole communicating with the outside is formed on the rear side wall of the cylindrical groove.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. First, install the support bar on the frame body, and then align and insert the support groove of the floor slab main body to complete the connection. The subsequent operation processes such as floor slab docking and I-shaped bar insertion are clear. Each component is closely matched. The installation steps are simple and easy to implement, which can significantly improve the construction efficiency, shorten the construction period of the building, and reduce the labor and time costs.
[0012] 2. Drive the driving mechanism through the rotating disk, so that the slider drives the insertion bar to extend into the limiting groove, realizing the limitation of the I-shaped bar and the floor slab main body. The rubber strip enhances the tightness and stability of the connection, can effectively bear various external forces received by the floor slab, and ensures the safety and durability of the building structure.
[0013] 3. After releasing the rotating disk, under the elastic action of the spring, the limiting rod is inserted into the limiting hole again to complete self-locking. The cooperation between the spring and the fine hole makes it necessary to apply a relatively large force to move the rotating disk back and forth, avoiding its reverse rotation due to vibration force or other factors, preventing the loosening of the limiting mechanism, further ensuring stable connection, and enhancing the overall reliability of the building structure.
[0014] 4. Adopt a concealed connection method in which the I-shaped strip cooperates with the main body of the floor slab. After installation, the connection part is not exposed, making the building appearance more concise and beautiful, meeting the requirements of modern architecture for aesthetics, and enhancing the overall quality and image of the building.

[0020] Refer to Figures 1-7 , a green and sustainable full-module prefabricated building structure, including two floor slabs 1, each floor slab 1 is provided with a through groove 2 running through from front to back, rectangular grooves 3 are opened on the opposite sides of the two through grooves 2, and each two matching through grooves 2 and rectangular grooves 3 together form an I-shaped groove, and an I-shaped bar 6 that can slide back and forth is arranged in the I-shaped groove; As an embodiment of the present invention, it further includes a limiting mechanism. The limiting mechanism is used to limit the I-shaped strip 6 and the two floor slabs 1. The limiting mechanism includes a rectangular cavity 7 opened in the I-shaped strip 6. Strip-shaped openings 12 are opened on the left and right inner walls of the rectangular cavity 7. Two sliders 8 are slidably connected in the rectangular cavity 7. On the opposite sides of the two sliders 8, insertion strips 9 are fixedly connected. On the opposite sides of the two insertion strips 9, rubber strips 10 are fixedly connected. The other side of each insertion strip 9 penetrates through the corresponding strip-shaped opening 12. Limiting grooves 11 are opened on the inner side walls of each through groove 2. The other end of each insertion strip 9 extends into the corresponding limiting groove 11; As an embodiment of the present invention, it further includes a plurality of support strips 5. A plurality of rectangular grooves 3 are opened at the lower end of each floor slab 1. Each support strip 5 penetrates through the corresponding rectangular groove 3; As an embodiment of the present invention, it further includes a driving mechanism. The driving mechanism is used to drive the two sliders 8 to move. The driving mechanism includes a bidirectional threaded rod 13 rotatably connected between the left and right inner walls of the rectangular cavity 7. The two threaded ends of the bidirectional threaded rod 13 penetrate through the corresponding sliders 8 and are threadedly connected. The threaded directions of the two threaded ends of the bidirectional threaded rod 13 are opposite. A first rotating shaft 16 is rotatably connected to the front side wall of the rectangular cavity 7. A second bevel gear 15 is fixedly connected to the rear end of the first rotating shaft 16. A first bevel gear 14 is installed on the bidirectional threaded rod 13. The first bevel gear 14 meshes with the second bevel gear 15. An operation groove 17 is opened on the front side of the I-shaped strip 6. The front end of the first rotating shaft 16 extends into the operation groove 17 and is fixedly connected to a second rotating shaft 23. A rectangular block 24 is fixedly connected to the front side of the second rotating shaft 23. A rectangular insertion slot 30 is opened on the front side of the rectangular block 24. A rectangular insertion block 31 that can slide back and forth is arranged in the rectangular insertion slot 30. The front side of the rectangular insertion block 31 is elastically connected to the rear inner wall of the rectangular insertion slot 30 through a spring 26. The front side of the rectangular insertion block 31 penetrates through the notch of the rectangular insertion slot 30 and is fixedly connected to a rotating disk 18. A cross slot 19 is opened on the front side of the rotating disk 18. A limiting hole 22 is provided through the eccentric part of the rotating disk 18 in the front and rear directions. A connecting strip 20 is fixedly connected to the right inner wall of the operation groove 17. A limiting rod 21 is fixedly connected to the rear side of the connecting strip 20. The rear end of the limiting rod 21 penetrates through the corresponding limiting hole 22 and is slidably connected; As an embodiment of the present invention, a cylindrical groove 27 is opened on the rear side wall of the rectangular insertion slot 30. A piston block 29 that can slide back and forth is arranged in the cylindrical groove 27. A piston rod 25 is fixedly connected to the front side of the piston block 29. The front end of the piston rod 25 is fixedly connected to the rear side of the rectangular insertion block 31. A thin hole 28 communicating with the outside is opened on the rear side wall of the cylindrical groove 27. Through the cooperation of the thin hole 28 and the spring 26, during use, a relatively large force is required for the rotating disk 18 to move back and forth, so that the limiting hole 22 is always inserted into the limiting hole 22, avoiding the situation that the rotating disk 18 is reversed due to vibration force or other factors, resulting in a reduction in connection stability.
[0021] In the present invention, first, a plurality of support bars 5 are installed on the framework of the floor slab to be installed, then the support grooves 4 of the floor slab main body 1 are aligned with the support bars 5 and then inserted to complete the connection, providing support for the floor slab main body 1. The two floor slab main bodies 1 are butted against each other so that the through grooves 2 formed thereon are opposite to each other. The two through grooves 2 and the rectangular grooves 3 on their opposite sides together form an I-shaped groove. Subsequently, the I-shaped bar 6 is inserted into the I-shaped groove so that it can slide back and forth; After pressing the rotating disk 18 to move backward so that the limiting rod 21 leaves the limiting hole 22, the rotating disk 18 in the operating groove 17 is rotated. The rotating disk 18 drives the second rotating shaft 23 to rotate through the rectangular insertion block 31. The second rotating shaft 23 drives the first rotating shaft 16 to rotate. The first rotating shaft 16 drives the second bevel gear 15 to rotate, and further drives the first bevel gear 14 meshing therewith to rotate. The first bevel gear 14 drives the bidirectional threaded rod 13 to rotate. Since the thread directions of the two threaded ends of the bidirectional threaded rod 13 are opposite and respectively penetrate through the corresponding sliders 9 and are threadedly connected, when the bidirectional threaded rod 13 rotates, the two sliders 8 move away from each other. The slider 8 drives the insertion bar 9 to slide in the strip-shaped opening 12, and the other end of the insertion bar 9 gradually extends into the corresponding limiting groove 11. The rubber strip 10 plays a certain buffering role, thereby realizing the limitation of the I-shaped bar 6 and the two floor slab main bodies 1; After the rotating disk 18 is released, under the elastic action of the spring 26, the rotating disk 18 resets, and the limiting rod 21 is inserted into the limiting hole 22 again to complete the self-locking operation. Further, under the cooperation of the spring 26 and the fine hole 28, a relatively large force is required for the rotating disk 18 to move back and forth, so that the limiting hole 22 is always inserted on the limiting rod 21, avoiding the reverse rotation of the rotating disk 18 due to vibration force or other factors, and ensuring the connection stability.
[0022] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
