[0002] In the field of construction, stepping boards are a common and important tool. Traditional stepping boards are usually made of bamboo plywood. However, these traditional stepping boards have many drawbacks. First, bamboo plywood stepping boards are heavy and inconvenient to carry, which puts a heavy burden on construction workers when transporting and arranging the stepping boards, reducing work efficiency. Second, the surface of traditional stepping boards is smooth, making it easy for workers to slip when walking on them, posing a certain safety hazard and threatening the lives of construction workers.

[0003] Furthermore, the width of traditional treads is fixed, while the spacing of the supports on the external frame varies. Since the width of the treads cannot be adjusted, they are not suitable for external frames with different support spacing. Therefore, in practical applications, treads often need to be customized according to the different external frame support spacing. This not only increases costs but also reduces the applicability and versatility of the treads, making them unable to meet diverse construction needs.

[0004] Finally, traditional treads are usually installed with screws. This installation method requires the use of specific tools during installation and removal, and the operation process is cumbersome and complicated, consuming time and manpower, which seriously affects the progress and efficiency of construction.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: a fixed external frame aluminum alloy pedal, including a steel external frame 1, the steel external frame 1 is an external frame for building construction, which has the functions of providing a construction operation platform, supporting and fixing the building structure, and ensuring the safety of construction workers. A pedal 2 is provided on the upper surface of the steel external frame 1, and the pedal 2 can provide support for the workers. The pedal 2 is made of aluminum alloy. Compared with the traditional bamboo plywood, it has the advantages of stable structure, large bearing capacity, and lightness. In addition, the upper surface of the pedal 2 is provided with anti-slip grooves to prevent people from falling. The pedal 2 is fixed to the steel external frame with fixing parts such as bolts or straps. 1, the left surface of the pedal 2 is penetrated and slidably connected with an extension plate 3, the upper surface of the extension plate 3 is also provided with anti-slip grooves, and two groups of extension plates 3 are provided, which are symmetrically distributed with the center line of the pedal 2. The upper surface of the pedal 2 is provided with a positioning component, which can control the position of the extension plate 3, and then can change the width of the pedal 2 and the extension plate 3, so that it can be applied to the steel outer frame 1 with different spacings, ensuring the practicality of the device. The rear surface of the pedal 2 is provided with a quick-release component, which can quickly install multiple groups of pedals 2 together, solving the problem of the traditional installation and disassembly using screws.

[0033] Reference Figure 2-Figure 4 The positioning assembly includes a threaded rod 41. The threaded rod 41 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The threaded rod 41 has self-locking properties. The inner wall of the bottom end of the pedal 2 is rotatably connected to a rotating shaft 42. The rotating shaft 42 is located at the center of the inner wall of the bottom end of the pedal 2. The outer wall of the threaded rod 41 is threadedly connected to a connecting block 43. When the threaded rod 41 rotates, it can drive the connecting block 43 to move longitudinally. The top of the threaded rod 41 is in the shape of a handwheel for easy gripping. The inner wall of the front side of the connecting block 43 is fixed. It is connected to a slider 44, and when the connecting block 43 moves longitudinally, it will drive the slider 44 to move longitudinally. An arc groove 401 is provided on the outer wall of the rotating shaft 42. When the arc groove 401 is squeezed, the rotating shaft 42 will rotate. The positioning assembly also includes a guide plate 45. The center point of the guide plate 45 is located on the same vertical line as the center point of the rotating shaft 42. The left end of the lower surface of the guide plate 45 is hinged to a connecting plate 46, and the left end of the upper surface of the connecting plate 46 is hinged to a hinge rod 47. There are two groups of connecting plates 46 and hinge rods 47, which are arranged in a circular array with the center of the guide plate 45.

[0034] Reference Figure 1-Figure 2 The quick-release assembly includes a card block 52, the lower surface of which is fixedly connected to one end of a compression spring 51. A card slot 501 is provided on the front surface of the pedal 2. The card block 52 corresponds to the card slot 501, but the initial position of the card block 52 is higher than the position of the card slot 501. When the two are plugged in, the card block 52 will be squeezed. A limiting groove 502 is provided at the front end of the upper surface of the pedal 2. The inner wall of the limiting groove 502 is slidably connected to a moving block 53, and the moving block 53 moves longitudinally.

[0035] Reference Figure 2-Figure 4 The threaded rod 41 passes through and is rotatably connected to the upper surface of the pedal 2. The connecting block 43 slides on the outer wall of the rotating shaft 42. The rotating shaft 42 can serve as a guide for the connecting block 43 to ensure that the connecting block 43 does not rotate during longitudinal movement. The inner wall of the connecting block 43 fits the outer wall of the rotating shaft 42. The slider 44 is slidably connected to the inner wall of the arc groove 401. When the slider 44 follows the longitudinal movement of the connecting block 43, it will squeeze the arc groove 401, thereby causing the rotating shaft 42 to rotate. The arc groove 401 is opened into an S shape. The guide plate 45 is fixedly connected to the middle section of the outer wall of the rotating shaft 42. When the rotating shaft 42 rotates, it will drive the guide plate 45 to rotate. The upper surface of the hinged rod 47 is fixedly connected to the lower surface of the extension plate 3. When the guide plate 45 rotates, it will drive the connecting plate 46 to swing, thereby driving the hinged rod 47 and the extension plate 3 to move.

[0036] Reference Figure 1-Figure 2 The block 52 passes through and is slidably connected to the rear surface of the pedal 2, sliding longitudinally. The rear end of the upper surface of the block 52 is provided with a wedge-shaped protrusion, and the rear surface of the wedge-shaped protrusion is set as an inclined surface. When the block 52 and the slot 501 are plugged in, the inclined surface of the rear surface of the wedge-shaped protrusion will be squeezed, thereby driving the block 52 to move downward, and the wedge-shaped protrusion fits into the limit groove 502. The other end of the compression spring 51 is fixedly connected to the inner wall of the bottom end of the pedal 2. When the block 52 moves downward, it squeezes the compression spring 51 to produce a reaction force, and the limit groove 502 and the slot 501 are connected. The block 52 is plugged into the inner wall of the slot 501. When the block 52 and the slot 501 are plugged in, the wedge-shaped protrusion will be aligned with the limit groove 502, and the block 52 is plugged into the inner wall of the limit groove 502, which can fix the two pedals 2 together.

[0037] Working principle: When using this device, first adjust the total width of the pedal 2 and the extension plate 3 according to the spacing of the steel pipes on the steel outer frame 1. When adjusting, first turn the handwheel at the top of the threaded rod 41 to drive the threaded rod 41 to rotate, and then drive the connecting block 43 to move longitudinally along the outer wall of the rotating shaft 42. When the connecting block 43 moves longitudinally, it drives the slider 44 to move longitudinally. The slider 44 slides on the inner wall of the arc groove 401 and squeezes the arc groove 401. Since the arc groove 401 is opened in an S shape, it will drive the rotating shaft 42 to rotate. The rotation of the rotating shaft 42 drives the guide plate 45 fixed on the middle section of its outer wall to rotate. The rotation of the guide plate 45 drives the connecting plate 46 to swing, and then drives the hinge rod 47 and the extension plate 3 to move, thereby changing the width of the pedal 2 and the extension plate 3 to adapt to the steel outer frame 1 with different spacing. When it is adjusted to the appropriate width, release the handwheel. The total width formed by the extension plate 3 and the pedal 2 will remain stable due to the self-locking nature of the threaded rod 41, and then the pedal 2 is installed on the steel outer frame 1.

[0038] When the two pedals 2 need to be quickly installed together, the block 52 on one pedal 2 is aligned with the slot 501 on the other pedal 2. The rear surface of the wedge-shaped protrusion at the rear end of the upper surface of the block 52 is an inclined surface. When the block 52 is plugged into the slot 501, the inclined surface of the wedge-shaped protrusion is squeezed, driving the block 52 to move downward. When the block 52 moves downward, it squeezes the compression spring 51 to produce a reaction force. When the block 52 and the slot 501 are completely plugged into each other, the wedge-shaped protrusion will be aligned with the limiting groove 502, and the reaction force of the compression spring 51 will push the wedge-shaped protrusion to move upward and plug into the limiting groove 502, thereby fixing the two pedals 2 together. When disassembly is required, the moving block 53 is pressed downward to squeeze the wedge-shaped protrusion to move it downward and disengage it from the limiting groove 502, and then the block 52 is removed from the slot 501 to complete the disassembly.
