Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for construction engineering. Background Art

[0002] Scaffolding is a common term in the construction industry. It is a variety of supports set up for workers on the construction site to operate and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration or places with high floors that cannot be directly constructed. It is convenient for construction workers to go up and down, maintain the outer safety net, and install components at high altitudes. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials.

[0003] A scaffold with prior art publication number CN220080713U comprises a support mechanism, wherein the support mechanism comprises two side frames and oblique bars crossing on both sides thereof, and the oblique bars are assembled and fixed by bolts; a pedal mechanism, wherein the pedal mechanism comprises a base plate and a hook, the hook is connected at the four corners of the base plate, and the hook is hooked on the top ends of the two side frames, movable grooves are provided on both sides of the top end of the base plate, an I-shaped block is slidably installed in the movable groove, an elastic band is connected to the I-shaped block, and a safety buckle is connected to the end of the elastic band for buckling on the worker's clothes.

[0004] In daily use, the side frame legs of the scaffolding are placed directly on the ground. Since each leg lacks a length adjustment mechanism, it has good stability when placed on a relatively flat ground. However, it has poor stability when placed on an uneven ground, and it is necessary to find suitable items to step on, which is not only troublesome but also has certain safety hazards. At the same time, the height of the footrest cannot be adjusted, which makes it difficult for workers to get good height support during construction. Therefore, improvements are proposed.
