Description

Technical Field

[0001] The utility model relates to the technical field of connection between plate walls and structural columns, in particular to a composite anti-cracking node at a plate wall steel structural column. Background Art

[0002] During the construction of building projects, lightweight panel walls, as a new type of wall material, are widely used and highly favored today as prefabricated materials are vigorously promoted. Currently, the most widely used panel walls include ALC (steamed lightweight concrete) panel walls, ceramsite concrete lightweight panel walls, etc., which are all prefabricated in the factory, transported to the site for assembly and installation. When the wall where the panel wall is located exceeds a certain scale, and the height or length exceeds the limit, the general practice is to set up ring beams and structural columns for reinforcement. The ring beams and structural columns that match the panel wall are often made of steel sections to achieve the convenient requirements of synchronous and rapid assembly.

[0003] However, the connection nodes between the plate wall and the ring beam and the structural column steel, especially the anti-crack treatment, has always been a difficult problem, which brings inconvenience to the subsequent decoration and has the following defects:

[0004] (1) The board wall and the steel are made of different materials, and the thermal expansion coefficients are quite different. Under the effect of thermal expansion and contraction, cracks are likely to appear at the junction, and will be reflected on the decorative layer, causing visual defects;

[0005] (2) If reinforcement measures are taken locally at the joints, such as increasing the strength or thickness of the decorative layer, the overall appearance will be affected due to the local thickening. If the same thickness decorative layer is used, the overall construction cost will increase. Utility Model Content
