Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a steel structure support frame for construction engineering. Background Art

[0002] Steel support frames are commonly used in construction projects to support and reinforce various parts of a building, particularly during the construction process and for long-term structural support. Common types of steel support frames include temporary, cantilever, wall, roof, and bridge supports. Their design and use must consider structural safety, stability, and construction efficiency. They provide temporary or long-term support, helping buildings maintain structural integrity and safety at various stages of construction.

[0003] The existing technology has the following deficiencies: during wall construction, especially for high-rise buildings or concrete structures, wall support frames can be used to support temporary formwork and concrete pouring; due to the long distance of wall construction, the wall support frames are usually composed of several repetitive identical structures, which results in the need to repeat the same steps each time the wall support frames are installed and removed, such as fixing bolts, adjusting the position of the support frames, etc. These steps are not only time-consuming, but may also affect the overall construction progress. At the same time, the installation and removal of the wall support frames may require a large amount of manpower, and may also require more personnel collaboration or specific tools to complete the task, which increases the complexity of the operation and the risk of construction.

[0004] Therefore, it is necessary to invent a kind of building engineering steel structure supporting frame. Utility Model Content
