[0025] Example

[0026] The utility model provides an improved subway floor connection structure, referring to Figure 1-3 As shown, it includes a floor body 1, one side of which is provided with a guide block 3 with a trapezoidal structure, one end of which is provided with a docking column 4 integrally formed therewith, and the end of the docking column 4 away from the guide block 3 is provided with a first mounting hole 5 for inserting the mounting bolt 2, and the floor body 1 on the opposite side of the guide block 3 is provided with a guide groove 7 for inserting the guide block 3 on the adjacent floor body 1. Through the arrangement of the guide block 3 and the guide groove 7, it is convenient for the staff to connect the two floor bodies 1 horizontally. The floor body 1 is also provided with a first mounting hole 5 for inserting the mounting bolt 2. A guide column 11 is provided on one side. The setting of the guide column 11 makes it easier for the staff to guide and connect the two floor bodies 1 longitudinally. Fastening columns 9 with a length shorter than the guide column are provided on the floor bodies 1 on both sides of the guide column 11. The fastening columns 9 are in an I-shaped structure. The setting of the fastening columns 9 improves the fastening of the longitudinal connection between the two floor bodies 1. A guide groove 17 and a fastening groove 16 for plugging the guide column 11 and the fastening column 9 on the adjacent floor body 1 are respectively provided on the end surface of the floor body 1 away from the guide column 11.

[0027] Furthermore, a lap groove 13 is provided on the top end surface of the floor body 1, and a lap plate 8 adapted to the lap groove 13 is provided on the floor body 1. By setting the lap plate 8 and the lap groove 13, the bearing capacity of the connection between the two floor bodies 1 is improved.

[0028] Furthermore, a limiting groove 14 with an inverted T-shaped structure is provided on the floor body 1 within the overlapping groove 13, and a limiting block 6 that fits with the limiting groove 14 is provided on the bottom end face of the overlapping plate 8. Through the setting of the limiting groove 14 and the limiting block 6, the stability of the connection between the two adjacent floor bodies 1 is improved.

[0029] The floor body 1 is provided with a docking groove for the docking column 4 to be inserted, and the docking groove is connected to the guide groove 7. The arrangement of the docking groove and the docking column 4 improves the horizontal connection strength between two adjacent floor bodies 1.

[0030] Among them, the floor body 1 is provided with a second mounting hole 10 connected to the first mounting hole 5. The setting of the first mounting hole 5 and the second mounting hole 10 improves the stability of the horizontal connection between the two adjacent floor bodies 1, and the second mounting hole 10 is a countersunk hole. The setting of the countersunk hole avoids affecting the splicing and installation of adjacent floor bodies 1.

[0031] Among them, the guide column 11 is provided with a fixing groove 12 at one end away from the floor body 1, and the guide groove 17 is provided with a fixing column that can be inserted into the fixing groove 12. Through the setting of the fixing column and the fixing groove 12, the longitudinal connection strength between the two adjacent floor bodies 1 is improved.

[0032] Among them, a first fastening hole 15 for inserting a fastening bolt is opened through the fastening column 9, and a second fastening hole connected to the first fastening hole 15 is opened on the bottom end surface of the floor body 1, and the second fastening hole is connected to the fastening groove 16. Through the setting of the first fastening hole 15 and the second fastening hole, the stability of the longitudinal connection between the two adjacent floor bodies 1 is improved.

[0033] The working principle and operation steps of the utility model are as follows:

[0034] When the floor body 1 is horizontally spliced and installed, the guide block 3 on the floor body 1 is aligned with the guide groove 7 on the adjacent floor body 1 and plugged in, so that the limit block 6 at the bottom of the overlap plate 8 is plugged into the limit groove 14 on the adjacent floor body 1. When the guide block 3 is plugged into the bottom of the guide groove 7, the docking column 4 is plugged into the docking groove in the adjacent floor body 1, so that the first mounting hole 5 on the docking column 4 is connected to the second mounting hole 10 on the adjacent floor body 1, and the mounting bolt 2 is inserted into the connected first mounting hole 5 and the second mounting hole 10 to fix them, thereby completing the horizontal splicing and installation of the two adjacent floor bodies 1.

[0035] When the floor bodies 1 are longitudinally spliced and installed, the guide columns 11 on the floor bodies 1 are aligned with the guide grooves 17 on the other floor bodies 1 and plugged in, so that the fixing columns in the guide grooves 17 are naturally plugged into the fixing grooves 12 in the guide columns 11. At the same time, the fastening columns 9 on both sides of the guide columns 11 are naturally plugged into the fastening grooves 16 on the other floor bodies 1, so that the first fastening holes 15 on the fastening columns 9 are connected with the second fastening holes on the other floor bodies 1. The fastening bolts are inserted into the connected first fastening holes 15 and the second fastening holes for fixing, thus completing the longitudinal splicing and installation of the two adjacent floor bodies 1.

[0036] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent.
