[0010] Compared with the existing technology, the beneficial effects of the present invention are as follows: the present invention can allow workers to climb to the corresponding height through the ladder. After the workers climb to the corresponding height, they can push the ladder to straighten the ladder so that the ladder is close to the end of the bracket body. Since the movable plate is rotatably connected to the crossbeam, the movable plate can be pushed to level the movable plate, thereby covering the climbing channel.

[0015] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0016] Example: Please refer to Figure 1-3 The scaffolding of claim 1, wherein the scaffolding has two bosses, one for mounting the scaffold on the support frame and the other for mounting the scaffold on the support frame. Passage 7, a movable plate 8 is provided at the climbing passage 7, and the movable plate 8 is hinged to the crossbeam; the transmission assembly 6 includes a first transmission rod 601 and a second transmission rod 602, one end of the first transmission rod 601 is rotatably connected to the bracket body 1, and the other end of the transmission rod is rotatably connected to one end of the second transmission rod 602, and the other end of the second transmission rod 602 is rotatably connected to the ladder 5, and the angle of the ladder 5 is adjusted by the transmission assembly 6. Specifically, the transmission assembly 6 is a prior art, and this application does not go into too much detail about it; when the staff climbs to a higher height, the ladder 5 is pulled out so that the ladder 5 is tilted 15-45 degrees, which is convenient for the staff to climb; when the staff is performing construction work, in order to ensure the safety of the staff, the climbing passage 7 needs to be closed to prevent the staff from stepping on air. For this, the ladder 5 needs to be pushed to the side to keep it upright, and then the movable plate 8 is flipped over so that it is placed flat on the crossbeam, thereby closing the climbing passage 7.

[0017] In an optional embodiment, the four corners of the bottom of the bracket body 1 are provided with universal wheels 9 with locking parts, and the universal wheels 9 can facilitate the movement of the bracket body 1; the universal wheels 9 are connected to the bracket body 1 through a height adjustment component 10, and the height adjustment component 10 includes a threaded rod 101 and a collar 102, the threaded rod 101 is passed through the interior of the vertical pole of the bracket body 1, and the outer diameter of the threaded rod 101 is smaller than the inner diameter of the vertical pole, and the collar 102 is threadedly connected to the threaded rod 101, the outer diameter of the collar 102 is larger than the outer diameter of the vertical pole, and the inner diameter of the collar 102 is smaller than the outer diameter of the vertical pole, so that the vertical pole It can rest against the top of the collar 102; rotate the collar 102 to make it rotate along the thread on the threaded rod 101. Depending on the direction of rotation, the collar 102 can rise or fall. When the collar 102 rises, it will push the upright pole to move upward. When the collar 102 falls, under the action of gravity, the upright pole will also fall and rest against the top of the collar 102. Therefore, the height of the upright pole can be adjusted by rotating the collar 102; individually adjusting the height of the collar 102 in each height adjustment component 10 can make the bracket body 1 adapt to uneven ground, thereby ensuring the stability of this high-safety construction scaffold.

[0018] In an optional embodiment, the bottom of the bracket body 1 is connected to an oblique brace 11 , and the number of the oblique brace 11 is at least two. The bottom of the oblique brace 11 is supported on the ground, which can further maintain the stability of the bracket body 1 .

[0019] In an optional embodiment, the bracket body 1 is connected to an inclined rod 12, which is used to provide safety protection for the working staff to prevent them from falling from a height, which is conducive to improving safety performance.

[0020] A tool box 13 is provided at at least one end of the bracket body 1 in the longitudinal direction. The tool box 13 is slidably connected to the bracket body 1 via a slide rail 14. The tool box 13 is used to place tools to provide convenience for operators.

[0021] The working principle of this embodiment is as follows: when in use, the height of the vertical pole is adjusted by rotating the corresponding ring 102, so that the bracket body 1 can adapt to the uneven ground. After the operator climbs up the ladder 5 to the corresponding height, the operator pushes the ladder 5 to adjust it to the upright state, flips the movable plate 8, and places it flat on the beam. At this time, the movable plate 8 and the sub-plate 4 fill the gap of 1 / 3-2 / 3 times the length of the horizontal bar 102 remaining in the related art, avoiding the situation where the workers walk back and forth on the upper and lower pedals 2 during construction and step on empty space, thereby reducing safety hazards.
