Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a lateral support structure at the junction of steel structure beams and columns. Background Technology

[0002] Steel structural beams and columns are widely used in modern steel structure buildings, especially suitable for large-span industrial plants, super high-rise buildings (such as skyscrapers), and commercial complexes (stadiums, airports, etc.). Their high strength and lightweight characteristics reduce structural volume and improve space utilization; the combination of factory prefabrication and on-site assembly significantly shortens construction time. Furthermore, they offer high design flexibility, allowing for complex shapes that balance functional and aesthetic needs, while also boasting a high recyclability rate, aligning with green and sustainable development principles.

[0003] The beam-column junction in a steel structure refers to the connection between beams and columns, often referred to as a node. This junction typically uses welding, bolting, or riveting to reliably connect the beam ends to the column. The lateral support structure at the beam-column junction is relatively simple in design and construction, making it difficult to effectively resist lateral forces under complex load conditions. It cannot provide sufficient lateral stiffness and load-bearing capacity, leading to significant deformation of the beam-column joint, which can cause structural damage and affect the long-term safety performance of the structure. Therefore, a lateral support structure for the beam-column junction is needed, employing welding and bolting to fix the beam and column together, while also using diagonal bracing for locking and vertical load-bearing to ensure the connection strength and load-bearing capacity of the beam and column. Utility Model Content

The end of the fourth bolt away from the connecting plate penetrates the base plate and is threaded to the base plate. A diagonal brace is welded to the side of the base plate away from the connecting plate. A locking assembly is provided at the top of the diagonal brace.

[0006] Preferably, six first bolts are provided through the side of the connecting plate away from the steel structure column, and one end of the first bolt passes through the connecting plate and is threadedly connected to the steel structure column.

[0007] Preferably, the locking assembly includes a support plate welded to the top of the diagonal brace, with a third bolt extending through the front and rear sides of the top of the support plate. A slidable locking clip is fitted onto the surface of the third bolt, and the locking clip is pressed against the surface of the steel structure beam.

[0008] Preferably, the top of the support plate contacts the bottom of the steel structure beam, and the front and rear sides of the bottom of the support plate are provided with arc-shaped grooves that are compatible with the third bolt.
