It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] The present utility model provides a floor structure based on an assembled building, such as Figure 1-Figure 6 As shown, the floor structure based on the prefabricated building includes:

[0033] The wall panel connector 100 is generally arranged on a wall, beam or other component supporting a floor slab of a prefabricated building; the wall panel connector 100 is connected to the supporting component in a fixed connection manner, and is usually assembled before the floor slab body is installed;

[0034] A floor 200, wherein a cavity area 210 is provided at the center of the floor 200, and no less than two groups of supporting square tubes 220 are provided inside the cavity area 210, and the length of the supporting square tubes 220 is kept flush with the floor 200; and abutting members 300 are respectively provided at both ends of the floor 200, and the abutting members 300 slide on the supporting square tubes 220;

[0035] The floor slab 200 is overlapped on the wall panel connector 100 through the abutting member 300. The abutting member 300 fills the gap between the floor slab 200 and the wall panel connector 100 under the sliding action, ensuring that both ends of the floor slab 200 can abut on the wall panel connector 100. In the present application, the supporting square tube 220 and the abutting member 300 are elastically connected, so that the abutting member 300 can effectively abut on the wall panel connector 100 during the assembly process, thereby enhancing the connection strength between the floor slab 200 and the wall panel connector 100.

[0036] The cavity area 210 may also be filled with sound insulation materials to improve the sound insulation effect of the floor;

[0037] As a preferred implementation in this embodiment, the abutting member 300 includes a connecting rod 310 and a pressing plate 320. The connecting rod 310 slides on the supporting square tube 220. The pressing plate 320 is arranged at one end of the connecting rod 310 away from the supporting square tube 220.

[0038] The connecting rod 310 includes a guide rod 311, a spring 312 and a rod body 313; the guide rod 311 is arranged at one end of the rod body 313 away from the pressure plate 320, and the spring 312 is nested around the guide rod 311; an end plate is arranged at one end of the guide rod 311 away from the pressure plate 320;

[0039] In the present embodiment, the supporting square tube 220 is provided with a limiting plate 240, and the limiting plate 240 is provided with a sliding hole for accommodating the guide rod 311 to pass through. The end of the guide rod 311 away from the pressure plate 320 passes through the sliding hole, and the diameter of the end plate is larger than the diameter of the sliding hole. Therefore, the end plate prevents the end of the guide rod 311 away from the pressure plate 320 from slipping out of the sliding hole, and one end of the spring 312 is abutted against the limiting plate 240 and the other end is abutted against the rod body 313. Under the action of the spring 312, the connecting rod 310 generally maintains a tendency to move toward the side of the pressure plate 320. When squeezed by an external force, the connecting rod 310 allows the spring 312 to deform to adapt to the change in the distance between the pressure plate 320 and the limiting plate 240.

[0040] As a preferred implementation in this embodiment, the wall panel connector 100 is provided with a mounting surface 110; the mounting surface 110 is adapted to the structure of the end of the abutment member 300 away from the supporting square tube 220; the mounting surface 110 is also provided with an embedding groove 120;

[0041] The end surface of the abutting member 300 away from the supporting square tube 220 is provided with a protrusion 330, and the protrusion 330 will be engaged in the embedding groove 120 during the assembly process; the end surface of the abutting member 300 away from the protrusion 330 is provided with a mounting groove 321, and the protrusion 330 is provided with a screw hole, which extends from the end surface of the abutting member 300 away from the supporting square tube 220 to one side of the mounting groove 321;

[0042] In this embodiment, a bolt is installed from one side of the installation groove 321 so that it passes through the protrusion 330 and is connected to the limiting screw hole provided in the embedded groove 120. During the assembly process, when the protrusion 330 and the embedded groove 120 are connected, the bolt can be further limited and locked;

[0043] As a preferred implementation in this embodiment, extension plates 230 are provided on both sides of the floor slab 200; the extension plates 230 on different sides are respectively kept flush with different end surfaces of the floor slab 200, so as to facilitate the construction and connection of different floor slabs 200;

[0044] Here’s how this application works:

[0045] First, the wall panel connector 100 is arranged at a suitable place. The wall panel connector 100 can also be formed in one piece with the prefabricated building. The building that does not adopt the one-piece forming technology is mainly assembled by bolt fixing;

[0046] After the wall panel connector 100 is completed, the floor slab 200 is placed on the corresponding wall panel connector 100 in sequence. Under the deformation of the abutting member 300, the floor slab 200 and the wall panel connector 100 are kept flush and the distance between them is adapted. When the protrusion 330 is inserted into the embedding groove 120, the bolt structure is used to fasten the connection, and the overall upper structure docking is completed.

[0047] After the above operations are completed, the gaps in the floor slab connection process are backfilled and sealed using the corresponding building materials;
