Detailed Implementation

[0017] This application discloses a detachable temporary construction staircase based on aluminum alloy formwork. By retracting the limiting block 51 into the sliding groove 41, the staircase base plate 40 can be installed between two staircase enclosures 20. The elastic force of the spring 52 causes the limiting block 51 to extend into the limiting groove 21, so that the insertion rod 53 can be inserted into the pin hole 511 on the limiting block 51, thereby fixing the staircase base plate 40 between the two staircase enclosures 20 and completing the installation of the temporary construction staircase.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 and Figure 2 This embodiment provides a detachable temporary construction staircase based on aluminum alloy formwork, including a base 10. Two staircase enclosures 20 are mounted on the top of the base 10. The two staircase enclosures 20 are fixed to the top of the base 10 by multiple support rods 30. Multiple staircase base plates 40 are disposed between the two staircase enclosures 20. An installation assembly 50 for fixing the staircase base plates 40 between the staircase enclosures 20 and the multiple staircase base plates 40 is provided between the staircase enclosures 20. Multiple limiting grooves 21 are formed on the inner side of the two staircase enclosures 20. The installation assembly 50 includes limiting blocks 51, springs 52, insert rods 53, push rods 54, and fixing blocks 55. The limiting blocks 51 are fixedly disposed on one side of the staircase base plate 40. The staircase base plate 40 is L-shaped, and the two limiting blocks 51 are disposed at both ends of the L-shape on one side of the staircase base plate 40. When the limiting blocks 51 are fixed, the staircase base plate 40... The plate 40 can be more stable. The limiting block 51 is slidably connected to the inside of the limiting groove 21. The top of the limiting block 51 is provided with a pin hole 511. The top of the stair railing 20 is provided with a slot 22. The slot 22 is connected to the limiting groove 21. The insertion rod 53 is slidably connected to the inside of the slot 22 and the pin hole 511. The slot 22 and the pin hole 511 are both inclined, and the inclination angle is the same as the inclination angle of the stair railing 20. This allows the insertion rod 53 to be inserted into the slot 22 and the pin hole 511 directly opposite the top of the stair railing 20. By inserting the limiting block 51 into the limiting groove 21 in the stair railing 20, and then inserting the insertion rod 53 from the slot 22 into the pin hole 511 at the top of the limiting block 51, the limiting block 51 can be fixed in the stair railing 20. This fixes the stair base plate 40 between the two stair railings 20, completing the installation of the temporary construction staircase.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3A groove 41 is provided on one side of the stair base plate 40. A limiting block 51 is disposed inside the groove 41, and a spring 52 is disposed inside the groove 41. The two ends of the spring 52 are respectively between the limiting block 51 and the inner wall of the groove 41. Multiple pins 60 are provided at the bottom of the bottom of the lowest stair base plate 40. The multiple pins 60 are arranged parallel to each other at equal intervals on the stair base plate 40. The stair base plate 40 is fixed to the base 10 by the multiple pins 60, and the pins 60 are inserted into the holes on the base 10. The bottom stair base plate 40 is fixed to the base 10. By retracting the limiting block 51 into the sliding groove 41, the stair base plate 40 can be placed into the two stair railings 20. The limiting block 51 is aligned with the limiting groove 21 on the stair railing 20. The spring force of the spring 52 causes the limiting block 51 to extend into the limiting groove 21. Then, the insert rod 53 is inserted into the pin hole 511 to complete the fixing of the limiting block 51, so that the stair base plate 40 is fixed between the two stair railings 20.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The push rod 54 is slidably connected to the inside of the limiting groove 21. One end of the push rod 54 is in contact with the limiting block 51. Fixing grooves 23 are provided on both sides of the limiting groove 21. Two fixing blocks 55 are fixedly set on both sides of the push rod 54. The two fixing blocks 55 are slidably connected to the inside of the two fixing grooves 23 respectively. The fixing grooves 23 are not connected to the outside of the stair base plate 40, so that the push rod 54 will not extend out of the stair base plate 40, preventing the push rod 54 from separating from the stair base plate 40. By pulling out the insert rod 53 from the pin hole 511, and then using the push rod 54 to push the limiting block 51 into the sliding groove 41, the stair base plate 40 is removed from the two stair panels 20, completing the disassembly of the stair base plate 40. The stair panels 20 can be installed and removed from the stair base plate 40 simply by inserting and pulling the insert rod 53 and the push rod 54. The operation is relatively simple, and the installation and disassembly are relatively convenient and quick, which is convenient for the temporary use of the construction staircase.

[0022] The functional principle of this application can be explained through the following methods:

[0023] In use, two stair railings 20 are installed on the base 10. Multiple support rods 30 at the bottom of the stair railings 20 support the stair railings 20. Then, the pin 60 on the bottom stair base plate 40 is aligned with the insertion hole on the base 10. The limiting blocks 51 on both sides of the stair base plate 40 are pressed, causing the limiting blocks 51 to retract into the slide groove 41. The spring 52 in the slide groove 41 is compressed. The limiting blocks 51 on the stair base plate 40 are aligned with the limiting groove 21 on the stair railing 20. When the stair base plate 40 is installed between the two stair railings 20, the limiting blocks 51 can extend into the limiting groove 21 due to the elastic force of the spring 52, pushing the push rod 54 inside the limiting groove 21 outward. The insertion rod 53 at the top of the stair railing 20 is pressed, causing the insertion rod 53 to extend from the slot 22 into the limiting block 5. In the pin hole 511 on the stair 1, the limiting block 51 is fixed in the limiting groove 21, thereby installing the stair base plate 40 on the two stair railings 20. After installing multiple stair base plates 40 in sequence, the installation of the temporary construction staircase is completed. When disassembly is required, the insert rod 53 is pulled out from the pin hole 511, and the push rod 54 on the outside of the limiting groove 21 is pushed, so that the push rod 54 drives the limiting block 51 in the limiting groove 21 to move towards the sliding groove 41, so that the limiting block 51 separates from the limiting groove 21, and the fixing of the stair base plate 40 to the stair railing 20 is released. The stair base plate 40 can then be removed from the two stair railings 20. After removing multiple stair base plates 40 in sequence, the stair railings 20 are removed, and the disassembly of the temporary construction staircase is completed. The operation is simple and the installation and disassembly are relatively convenient.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
