Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a connection device for civil engineering steel frame nodes. Background Art

[0002] Steel structure modular building is a highly prefabricated building, which divides traditional houses into single rooms or certain three-dimensional building spaces as building module units. It can be prefabricated in the factory in advance and transported to the site for installation and connection. In the building steel frame, the vertical beams are made of square steel pipe columns, and the horizontal beams are made of "H"-shaped steel beams or "I"-shaped steel beams. The connection quality of the two is the key to the structural bearing capacity and seismic resistance. Traditional steel structure node connections generally adopt butt welding or a combination of welding and bolts.

[0003] An assembled plug-in steel frame beam-column node is disclosed in Chinese patent CN220521562U. The assembled plug-in steel frame beam-column node is provided with a first connection node and a second connection node on the column and the steel beam, respectively, so that the steel beam and the column can be quickly positioned during installation, while reducing the operation of installing a temporary positioning and fixing device, reducing the difficulty of construction, and reducing the labor intensity of workers. However, while solving the problem, the connection device of this type of steel frame node has the following disadvantages: the two commonly used methods of welding or bolt connection both require the steel structure frame to be lifted by a crane, slowly aligned to the position, and then fixed and installed together. This process is time-consuming and labor-intensive, and cannot be quickly positioned and installed. Utility Model Content
