DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of those skilled in the art, the following embodiments and attached Figure 1-4 To further illustrate the present invention, the contents mentioned in the implementation modes are not intended to limit the present invention.

[0019] See Figure 1-4A simple scaffolding comprises a scaffolding body 1, vertical poles 11 are arranged at the four corners of the scaffolding body 1, a connecting rod 12 is fixed between the tops of the two vertical poles 11 on the left and right sides of the scaffolding body 1, a supporting screw 13 is screwed at the bottom of each vertical pole 11, a supporting plate 14 is screwed at the bottom of the supporting screw 13, guardrails 2 are inserted at the tops of the two vertical poles 11 on the left and right sides of the scaffolding body 1, and a retractable diagonal brace 3 is hinged at the middle of each connecting rod 12.

[0020] The simple scaffolding of the utility model is provided with support screws 13 screwed at the bottom of each vertical upright 11, so that the height of the scaffolding can be adjusted as needed, which is safe and stable; and the left and right sides of the scaffolding body 1 are plugged with guardrails 2, which can effectively prevent the operator from accidentally falling during the construction process and ensure the personal safety of the operator; in addition, the setting of the diagonal brace rods 3 can support the mobile scaffolding and prevent the mobile scaffolding from overturning. The utility model has a simple structure, is easy to use, and is highly practical.

[0021] In this embodiment, each vertical pole 11 has a first threaded hole 111 along its length direction, which matches the support screw 13, and the top of the support screw 13 is screwed into the first threaded hole 111. The above structure is convenient for adjusting the height of the scaffold.

[0022] In this embodiment, a mounting seat 15 is fixed at the center of the top of the support plate 14, a second threaded hole 151 matching with the support screw 13 is formed at the top of the mounting seat 15, and the bottom of the support screw 13 is screwed into the second threaded hole 151. The above structure is convenient for installation and replacement of the support plate 14.

[0023] In this embodiment, reinforcing ribs 152 are welded between the two sides of the mounting seat 15 and the top of the support plate 14. The above-mentioned structure can improve the support strength of the support plate 14.

[0024] In this embodiment, gripping blocks 141 are fixed on both sides of the bottom of the support plate 14. The gripping blocks 141 are suitable for use in places with soft ground, such as muddy ground. The gripping blocks 141 can be embedded in the soft ground to prevent the scaffold from sliding.
