Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction engineering, and in particular to a scaffolding for construction engineering. Background Technology
[0002] Scaffolding is a common temporary facility in construction projects, primarily used to support workers and building materials, ensuring safety and convenience when performing work at heights on the exterior or interior of buildings. It typically consists of steel pipes, couplers, bases, casters (if mobile), platform boards, and safety nets. Depending on the specific needs of the project, scaffolding can be erected in various forms, such as ground-mounted, cantilevered, or attached and lifting types. It is indispensable not only in new construction projects but also plays a vital role in decoration, maintenance, and exterior wall cleaning.
[0003] Scaffolding is a movable three-dimensional platform. To ensure its stability, its base is generally designed as a fixed structure that cannot be extended or shortened. In situations where there are height differences or uneven ground surfaces, it is often necessary to level the ground before construction so that the top of the scaffolding can be close to the construction position. In practice, suitable leveling materials may be difficult to find, leading to delays in construction. Even if usable materials are found, they may not be strong enough and may break during construction, causing the scaffolding to collapse. This not only damages building materials but, more seriously, may cause workers to fall and get injured or even die, posing a significant threat to the safety of the construction site. Utility Model Content
[0004] To overcome the drawback of needing to level the ground before the top of the scaffolding can be close to the construction site on uneven ground, the purpose of this utility model is to provide a construction scaffolding with individual adjustable support legs.
[0005] A type of scaffolding for construction projects includes a support pipe, mounting rods, reinforcing rods, a workbench, a rotating pipe, and a lifting rod. Mounting rods are installed at the top of the support pipe, with symmetrical reinforcing grooves on both sides of the mounting rods. Reinforcing rods are symmetrically hinged to the bottom of the support pipe, with their tops snapped into the reinforcing grooves. A workbench is rotatably connected to one side of the support pipe, and the other end of the workbench is snapped into the mounting rod at the other end. A rotating pipe is rotatably installed at the bottom of the support pipe, with internal threads inside and a slot on the outside. A lifting rod is threadedly connected to the rotating pipe, with external threads on the outside of the lifting rod. The external threads are threadedly connected to the internal threads. A limiting groove is provided at the end of the support pipe, and the limiting groove is rotatably snapped into the rotating pipe.
[0006] In one embodiment, the device further includes a sliding ring, a retaining ring, and a fixing block. The fixing block is installed at the bottom of the support tube, and a retaining ring is slidably disposed inside the fixing block. A sliding ring is slidably disposed outside the retaining ring. The sliding ring is slidably connected to the support tube, and the retaining ring is engaged with the retaining groove.
[0007] In one embodiment, the outer side of the rotating tube has anti-slip texture.
[0008] In one embodiment, a positioning block is also included, which is disposed inside the support tube and is engaged with the end of the lifting rod.
[0009] In one embodiment, a pin is also included, with the end of the reinforcing rod having a pin that is movably inserted into the reinforcing groove.
[0010] In one embodiment, casters are also included, with casters installed at the bottom of each rotating tube.
[0011] In one embodiment, an anti-slip mat is also included, with the top of the workbench affixed with an anti-slip mat.
[0012] The beneficial effects of this utility model are as follows: By rotating the lifting rod, the external thread inside the lifting rod moves along the internal thread of the rotating tube. The lifting rod extends and retracts inside the support tube, lengthening or shortening the support tube, thus achieving the effect of adjusting the length of the support tube individually. This provides high flexibility and makes it suitable for ground conditions with height differences or uneven surfaces, thereby improving the safety of this utility model. Attached Figure Description
