[0024] A rotating rod 4 is rotatably installed inside the two first bearings 3, and a connecting plate 5 is fixedly installed on the opposite side of the two rotating rods 4. The connecting plate 5 is rotated 90 degrees by rotating the rotating rod 4, and the connecting plate 5 is rotated to fit the side of the step body 1. When in use, the connecting plate 5 is rotated 90 degrees in the opposite direction so that the connecting plate 5 fits the side of the pedal 2.

[0025] The inside of the two connecting plates 5 are both threadedly connected with a screw rod 6, and a threaded hole is opened inside the connecting plate 5. The screw rod 6 is threadedly connected to the connecting plate 5 through the threaded hole, which facilitates the screw rod 6 to rotate and move inside the connecting plate 5, thereby achieving the purpose of adjusting the position of the mounting plate 8.

[0026] The second bearings 7 are rotatably mounted on opposite sides of the two screw rods 6 , and a second mounting groove is provided on the outer side of the mounting plate 8 , through which the second bearings 7 are fixedly connected to the mounting plate 8 .

[0027] A mounting plate 8 is fixedly installed on the opposite side of the two second bearings 7, and a plug-in rod 9 is fixedly installed on the opposite side of the two mounting plates 8. Plug-in holes are provided on both sides of the pedal 2, and the plug-in rod 9 is plugged with the pedal 2 through the plug-in holes. The pedal 2 and the step body 1 are quickly installed, reducing the need to install the pedal 2 and the step body 1 in a fixed manner by fasteners or interlocking, making installation and disassembly more convenient, facilitating the improvement of the efficiency of stair construction and installation, and facilitating the fixing of handles 10 on the opposite sides of the two screw rods 6.

[0028] It should be noted that the installation and fixing structure of the prefabricated concrete staircase is convenient for quickly installing the pedal 2 and the step body 1 by installing a fixing component, reducing the installation method of fixing the pedal 2 and the step body 1 by fasteners or interlocking, making installation and disassembly more convenient, facilitating improving the efficiency of stair construction and installation, and improving the practicality of the device.

[0029] Specifically, the assembled concrete staircase installation fixing structure is installed. When installing, the pedal 2 is placed on the step body 1, and then the two rotating rods 4 are rotated to synchronously drive the two connecting plates 5 to rotate, so that the connecting plates 5 are rotated to the side of the pedal 2. Then, by rotating the two handles 10, the two screw rods 6 are driven to rotate and move on the connecting plates 5, and the two mounting plates 8 are synchronously driven to move, so that the two sets of plug-in rods 9 move in opposite directions, and the pedal 2 is plugged and limited, and then the pedal 2 is fixed on the step body 1, reducing the installation method of fixing the pedal 2 and the step body 1 by fasteners or interlocking, making installation and disassembly more convenient.

[0030] The reserved component includes a bolt 11 fixedly mounted on the top of the step body 1 , and extension holes are provided inside the pedal 2 and at the bottom of the mounting frame 12 , through which the bolt 11 extends to the inside of the mounting frame 12 .

[0031] A mounting frame 12 is inserted into the top of the pedal 2, and a handrail 13 is fixedly installed on the top of the mounting frame 12. A nut 14 is threadedly connected to the outer side of the bolt 11. The nut 14 is used in conjunction with the bolt 11 to facilitate fixing the mounting frame 12 on the pedal 2, thereby facilitating the installation of the handrail 13 and improving the flexibility of the device.

[0032] It should be noted that the fixed structure of the assembled concrete staircase is installed with a reserved component, which facilitates the rapid installation of the handrail 13 and the step body 1, and also facilitates the disassembly and replacement of the handrail 13, thereby improving the flexibility of the device.

[0033] Specifically, the assembled concrete staircase installation fixing structure is to put the installation frame 12 on the pedal 2, so that the bolt 11 extends to the inside of the installation frame 12 through the extension hole, and then the nut 14 is threadedly connected with the bolt 11 to fix the installation frame 12 on the pedal 2, thereby facilitating the installation and fixation of the handrail 13, making the installation of the handrail 13 more convenient, and also facilitating the disassembly and replacement of the handrail 13, thereby improving the flexibility of the device.

[0034] The working principle of the above embodiment is:

[0035] (1) The assembled concrete staircase installation fixing structure is installed by placing the pedal 2 on the step body 1, then rotating the two rotating rods 4, synchronously driving the two connecting plates 5 to rotate, so that the connecting plates 5 rotate to the side of the pedal 2, and then rotating the two handles 10 to drive the two screw rods 6 to rotate and move on the connecting plates 5, synchronously driving the two mounting plates 8 to move, so that the two sets of plug-in rods 9 move in opposite directions, plugging and limiting the pedal 2, and then fixing the pedal 2 on the step body 1, reducing the need to install the pedal 2 and the step body 1 by means of fasteners or interlocking, making installation and disassembly more convenient.

[0036] (2) The mounting and fixing structure of the assembled concrete staircase is such that the mounting frame 12 is mounted on the pedal 2, so that the bolt 11 extends through the extension hole to the inside of the mounting frame 12, and then the nut 14 is threadedly connected with the bolt 11 to fix the mounting frame 12 on the pedal 2, thereby facilitating the installation and fixing of the handrail 13, making the installation of the handrail 13 more convenient, and also facilitating the disassembly and replacement of the handrail 13, thereby improving the flexibility of the device.
