[0002] Under the background of the rapid development of the modern construction industry, prefabricated buildings have become an important direction for the development of building industrialization due to their advantages such as high construction efficiency, low environmental pollution, and controllable quality.

[0003] During the installation of prefabricated floors, the existing floor connection methods lack accurate guiding and positioning mechanisms, resulting in a complex floor installation process. Not only is the installation efficiency low, but it is also difficult to ensure the installation accuracy. Moreover, the connection method between adjacent floors after connection is not reliable enough, and loosening is likely to occur during the use of the building, affecting the service life of the building. Therefore, we designed a floor connection structure for prefabricated beams of prefabricated buildings to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Referring to Figures 1 - 4 , a floor connection structure of a precast beam for an assembled building, including columns 1, and the number of columns 1 is set to be multiple. The columns 1 serve as the support foundation of the entire structure to bear and transfer the loads of the upper structure to the ground. A fixed frame 2 is fixedly connected to the outer wall of each column 1. Each pair of fixed frames 2 is jointly fixedly connected with a cross beam 3. The cross beam 3 is arranged horizontally to bear the vertical load transmitted by the floor body 9 and disperse it to the columns 1. Each pair of fixed frames 2 is jointly fixedly connected with a vertical beam 4. The vertical beam 4 is longitudinally arranged to jointly form a rectangular frame with the cross beam 3 to enhance the overall stability of the structure. The two cross beams 3 and the vertical beam 4 are adjacent and staggered, and their positions are arranged in a rectangle. A strengthening beam 7 is installed between the two vertical beams 4. The two ends of the strengthening beam 7 can be fixedly connected to the main building structure through bolts. The strengthening beam 7 further improves the load-bearing capacity and anti-deformation ability of the structure. Placement grooves 5 are opened at the tops of the two vertical beams 4. The strengthening beam 7 is located in the placement grooves 5 and abuts against the inner bottom of the placement grooves 5. Two first insertion posts 6 are fixedly connected to the inner bottom of each placement groove 5. The first insertion posts 6 play a role in preliminary positioning and guiding to assist the accurate installation of the strengthening beam 7. Two pairs of first insertion holes 8 are opened on the strengthening beam 7. The four first insertion posts 6 are respectively inserted into the corresponding first insertion holes 8. The cooperation between the first insertion posts 6 and the first insertion holes 8 realizes the preliminary fixation of the strengthening beam 7 and the vertical beam 4.

[0021] A plurality of floor bodies 9 are installed between each cross beam 3 and the strengthening beam 7. The floor bodies 9 serve as the horizontal load-bearing members of the building to bear loads such as personnel and equipment and transfer them to the cross beam 3 and the strengthening beam 7. A plurality of pairs of second insertion posts 10 are fixedly connected to the tops of the cross beam 3 and the strengthening beam 7. Two second insertion holes 11 are respectively penetrated and opened at both ends of each floor body 9. Each pair of second insertion posts 10 is respectively inserted into the corresponding pair of second insertion holes 11. The second insertion posts 10 play a role in guiding and preliminary positioning for the installation of the floor body 9. An assembly mechanism is provided between two adjacent floor bodies 9. The assembly mechanism includes two T-shaped blocks 12 fixedly connected to the side walls of the floor body 9. Two T-shaped grooves 13 are opened on the other floor body 9. The two T-shaped blocks 12 are respectively inserted into the corresponding T-shaped grooves 13. The cooperation between the T-shaped blocks 12 and the T-shaped grooves 13 realizes the preliminary limit splicing of adjacent floor bodies 9.

[0022] A rotating rod 16 is penetrated through the floor slab body 9 and is rotatably connected thereto. A handle 15 is fixedly connected to the bottom of the rotating rod 16. A receiving groove 14 is formed in the bottom of the floor slab body 9. The handle 15 is arranged in the receiving groove 14. The receiving groove 14 provides a storage space for the handle 15 to avoid affecting the overall flatness after the installation of the floor slab. A driving bevel gear 17 is fixedly connected to the top of the rotating rod 16. The driving bevel gear 17 meshes with two driven bevel gears 18. Two threaded rods 19 are coaxially and fixedly connected to the two driven bevel gears 18 respectively. The two threaded rods 19 are rotatably connected to the floor slab body 9. The outer walls of the two threaded rods 19 are sleeved with moving limit posts 20 which are threadedly connected thereto. The threaded rods 19 drive the moving limit posts 20 to move through threaded transmission to further fix the adjacent floor slab bodies 9. The two moving limit posts 20 penetrate through the floor slab body 9 and are slidably connected thereto. The cross section of the moving limit post 20 is rectangular. External threads are provided on the outer walls of the threaded rods 19. Grooves are formed in the moving limit posts 20, and internal threads matching the external threads are provided on the inner walls of the grooves. Limit slots 21 are formed in each T-shaped block 12. The two moving limit posts 20 are respectively inserted into the corresponding limit slots 21. The connection stability between the adjacent floor slab bodies 9 is enhanced by inserting the moving limit posts 20 into the limit slots 21.

[0023] A limit mechanism is arranged between each floor slab body 9 and the cross beam 3. The limit mechanism includes a connecting column 22 fixedly connected to the bottom of the floor slab body 9. A fixing block 23 is fixedly connected to the side wall of the cross beam 3. An installation groove 24 is formed in the top of the fixing block 23. The connecting column 22 is inserted into the installation groove 24. The connecting column 22 is used to be inserted into the installation groove 24 to realize the preliminary positioning of the floor slab body 9 and the cross beam 3. Two limit clamping rods 25 are penetrated through the fixing block 23 and are slidably connected thereto. The limit clamping rods 25 are used to be inserted into the limit clamping grooves 28 to realize the firm connection between the floor slab body 9 and the cross beam 3. The two limit clamping rods 25 are fixedly connected to a connecting handle 26 together. A spring 27 is sleeved on the outer wall of each limit clamping rod 25. The two ends of each spring 27 are respectively fixedly connected to the fixing block 23 and the connecting handle 26. The spring 27 provides a restoring force to ensure that the limit clamping rod 25 is inserted into the limit clamping groove 28. Two limit clamping grooves 28 are formed in the connecting column 22. The two limit clamping rods 25 are respectively inserted into the corresponding limit clamping grooves 28. The reliable connection between the floor slab body 9 and the cross beam 3 is completed through the cooperation of the limit clamping rods 25 and the limit clamping grooves 28, ensuring the stability of the floor slab installation.

[0024] In the present invention, during the assembly process, the column 1 is installed and fixed to the ground through bolts. Finally, the staff installs and fixes the cross beam 3 to the column 1 and the vertical beam 4 to the column 1 through bolts to complete the assembly of the preliminary framework. The staff then uses a hoisting vehicle to hoist the strengthening beam 7 onto the two placement grooves 5, and inserts the first insertion post 6 into the first insertion hole 8 to complete the assembly of the strengthening beam 7. The staff then uses the hoisting vehicle to sequentially place multiple floor body 9 onto the cross beam 3 and the strengthening beam 7. During the hoisting process, the second insertion post 10 first inserts into the second insertion hole 11 for guiding, and then the T-shaped block 12 is inserted into the T-shaped groove 13 to complete the limiting. The staff can hold the handle 15 and rotate it to drive the rotating rod 16, the driving bevel gear 17, the two driven bevel gears 18, and the threaded rod 19 to rotate, so that the moving limiting posts 20 on both sides move away from each other until the moving limiting posts 20 are inserted into the corresponding limiting grooves 21 to complete the installation and fixation of two adjacent floor body 9. When the floor body 9 is placed on the cross beam 3 and the strengthening beam 7, at this time, the connecting column 22 is inserted into the installation groove 24. During the insertion process, the staff holds the connecting handle 26 and moves it in a direction away from the fixed block 23. During this process, the spring 27 is stretched, and the movement of the connecting handle 26 drives the two limiting latch rods 25 to move. During this process, the spring 27 is stretched until the connecting column 22 is completely inserted into the installation groove 24. At this time, the two springs 27 are released, and under the action of the two springs 27, the limiting latch rods 25 are inserted into the corresponding limiting latch grooves 28 to complete the plug-in fixation of the connecting column 22, ensuring the installation and limiting of the floor body 9 and realizing the assembly and fixation of multiple floor body 9.
