Technical Field

[0001] The utility model relates to the technical field of foundation pit connectors, in particular to a detachable L-shaped steel support connector. Background Art

[0002] L-shaped steel is a structural steel with an L-shaped cross-section. It is made by hot rolling or cold bending, and its cross-section is a ninety-degree L-shape. L-shaped steel has good mechanical properties and bearing capacity, and is widely used in construction, engineering structures, bridges, and foundation pit enclosures. When L-shaped steel supports are used in foundation pits, the two ends of the commonly used L-shaped steel are supported on the connecting parts that need to be set on the foundation pit baffles. The L-shaped steel support and the foundation pit baffle are connected through the connecting parts.

[0003] Most of the existing connectors are fixed to the foundation pit baffle by welding, which makes the connector unable to move, and thus the L-shaped steel fixing position cannot be properly adjusted according to construction needs, resulting in deviation or deformation of the L-shaped steel position and inability to adjust. New steel sections need to be replaced, which leads to high steel consumption and increased cost investment. At the same time, after the construction is completed, the connector needs to be de-welded before the foundation pit baffle and the connector can be removed, thereby reducing the overall construction efficiency. Therefore, in response to the above problems, we propose a detachable L-shaped steel support connector. Utility Model Content

It is necessary to replace it with a new steel, which leads to high steel consumption and increased cost investment. At the same time, after the construction is completed, the connector needs to be de-welded before the foundation pit baffle and the connector can be removed, thereby reducing the overall construction efficiency.
