Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a convenient-to-use building construction scaffold. Background Art

[0002] The scaffolding is a working platform set up to ensure the smooth progress of each construction process. As the demand for use continues to increase, the traditional scaffolding with a single structure that can only provide support is obviously unable to meet the needs of use. Therefore, researchers in related fields are constantly improving the scaffolding. For example, the patent document with application number 202122454830.X proposes that "the scaffolding used for construction of the building project can use the scaffolding as a whole to transport materials during use. The equipment for transporting logistics has a strong integrity with the scaffolding and is easy to transport, which makes it convenient to directly transfer materials up and down, and a safety mechanism is also provided on the scaffolding of the device. , can prevent materials from falling quickly during material transportation, ensure the overall safety of the device, avoid safety accidents, and meet the needs of users". However, it can be learned from the detailed description and drawings of the above-mentioned prior art that the implementation of its technical solution is based on one side edge of the scaffolding. Although it theoretically achieves the operating effect of material lifting, it actually has a great impact on the center of gravity offset of the scaffolding. Secondly, even if the prior art sets its material transport device in the middle of the scaffolding, the specific winch and related structures will occupy most of the space on the top of the scaffolding, which is not conducive to the walking of construction workers. Secondly, the implementation of the prior art needs to rely on intact power facilities, and its use is relatively restricted. Utility Model Content
