In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0031] like Figure 1 and Figure 2 As shown in the figure, an embodiment of this utility model provides a device to prevent trampling on slab reinforcement bars, including a footboard, a support rod, and a track 4. The footboard is mounted above the slab reinforcement bars 16, and the support rod is mounted on the base plate 15 below the slab reinforcement bars 16. The footboard is fixedly connected to the top of the support rod to support the footboard. For ease of installation, the support rod is designed as a telescopic structure to adjust the support height of the footboard. To facilitate the transportation of construction tools and materials using a trolley 14 on the footboard, a track 4 is fixed on the footboard, allowing construction workers to push the trolley 14 along the track 4.

[0032] Preferably, the pedal includes multiple separate pedals 1, which are spliced ​​together. By separating the pedals, the multiple separate pedals 1 can be arbitrarily spliced ​​according to the size of the stepping area, and dividing the pedal into multiple separate pedals 1 makes it easier to move and store.

[0033] Specifically, the split pedal 1 includes parallel steel frames 2, with steel mesh 3 fixedly connected between the steel frames 2. The steel frames 2 ensure the rigidity of the pedal and prevent deformation from foot pressure. Each split pedal 1 includes two parallel steel frames 2, with a track 4 running along the steel frames 2 and fixedly connected to them, located on the inner side of the steel frames 2. A support rod is fixed to the bottom of the steel frames 2.

[0034] Specifically, one end of the steel frame 2 has a groove 5, and the other end is fixed with a pin 6. The groove 5 and the pin 6 are compatible. Between adjacent split pedals 1, the pin 6 of one split pedal 1 can be inserted into the groove 5 of the adjacent split pedal 1 to realize the splicing of the split pedals 1.

[0035] Specifically, the support rod includes an upper connecting rod 7 and a lower support rod 8. The upper connecting rod 7 is sleeved inside the lower support rod 8 and can move along the lower support rod 8. By adjusting the relative position of the upper connecting rod 7 and the lower support rod 8, the length of the entire support rod can be adjusted.

[0036] In some embodiments, such as Figure 2 As shown, the upper connecting rod 7 is a solid circular rod with external threads at the bottom, and the lower support rod 8 is a circular tube with internal threads at the top, with the external and internal threads matching each other. By turning the lower support rod 8, the relative positions of the upper connecting rod 7 and the lower support rod 8 can be adjusted, thereby adjusting the length of the entire support rod.

[0037] In some embodiments, such as Figure 3 As shown, the upper connecting rod 7 is a circular tube with multiple positioning holes 9. These positioning holes 9 are evenly spaced along the length of the upper connecting rod 7. The lower support rod 8 is also a circular tube with positioning pins 10. Specifically, the positioning pins 10 are positioning bolts, horizontally inserted into the lower support rod 8 and threadedly connected to it. The positioning pins 10 can connect to positioning holes 9 at different heights, adjusting the relative position of the upper connecting rod 7 and the lower support rod 8 to achieve adjustment of the entire support rod length.

[0038] Preferably, the bottom of the lower support rod 8 is provided with a horizontal support part 11, which makes the support more stable.

[0039] Preferably, the track 4 is provided with a placement plate 12 for placing construction tools or construction materials. In order to prevent construction tools and materials from having nowhere to be placed during the construction process, such as small parts such as bolts and shims that are easy to fall onto the base plate 15 and are difficult to clean, thus affecting the pouring quality of the floor slab, a placement plate 12 is provided on the track 4 to place construction tools or construction materials.

[0040] Specifically, such as Figure 4 As shown, the placement plate 12 is L-shaped and engages with the track 4. The placement plate 12 is made of plastic, with the long side of the L-shape used to place construction tools and materials, and the short side of the L-shape having a bend 13 that engages with the track 4.
