Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a ground-mounted external scaffolding. Background Technology

[0002] Ground-supported external scaffolding is a temporary construction facility erected along the ground, foundation, or floors of a building using uprights, horizontal bars, and diagonal braces. It is mainly used during the construction process to provide construction workers with an operating platform for external wall construction, facilitating bricklaying, plastering, and door and window installation. It also serves as a safety protection facility to prevent construction workers and materials from falling from heights.

[0003] A search revealed Chinese patent publication number CN208105844U, which discloses an improved structure for wall ties in ground-supported external scaffolding. This structure includes L-shaped flat irons pre-embedded in concrete beams. One end of the L-shaped flat iron is pre-embedded in the concrete beam and welded to the main reinforcement; the other end connects to the scaffolding when the L-shaped flat iron is straightened after the formwork is removed. This utility model has a simple structure and is easy to operate. The use of L-shaped flat irons avoids the need to embed steel pipes in the concrete beams, and also avoids the situation where holes are exposed after the steel pipes are removed, leading to forgetting to embed them. Instead, it can be directly cut later and welded to the horizontal steel pipes of the scaffolding, greatly increasing the firmness of the connection between the scaffolding and the horizontal beams. This reduces the safety hazards caused by the pre-embedded horizontal bars of the scaffolding coming loose or twisting during operation. However, ground-supported external scaffolding is too large, requiring complex steps for fixing the bottom, wasting time and manpower. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a ground-mounted external scaffolding, which aims to improve the problem in the prior art that requires complicated steps for fixing the corresponding bottom, wasting time and manpower.
