Connecting piece for steel structure building

Abstract

The invention discloses a connecting piece for a steel structure building. The connecting piece comprises a connecting plate, a fixing hole, an inner cavity, an upper ring sleeve body, a trapezoidal bottom beam, axillary ribs and fixing nuts, wherein a wrapping wing is welded on the inner end edge of the connecting plate; the connecting plate is symmetrically arranged at two sides of an arc-shapedfixing region to form a rectangular fixing region; the axillary ribs are fixedly inserted into an arc-shaped peak region of fixing studs; and the fixing nuts are fixedly connected at two ends of thefixing studs to form a connection state of stabilizing the fixing studs. An outer cavity and the inner cavity of the connecting piece provided by the invention can completely cover and connect connected components; meanwhile, the connected components penetrating into the inner cavity can produce an effect of acting force offsetting with the connected components fixed by the rectangular fixing region below a lower ring sleeve body, and the connected components fixed by the arc-shaped fixing region and the wrapping wing; and the setting of a plurality of fixing bolts greatly increases the flexible selectivity of the connecting piece provided by the invention when being connected with the connected components, so that the connecting piece is not limited by a fixed size, is flexible to change,has high creativity and is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a connecting piece used in steel structure buildings. Background technique [0002] Steel connectors are metal parts used to connect steel components, wood components, and steel and wood components. Steel structures are structures composed of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and is widely used in large factories, stadiums, super high-rises and other fields. steel structure [0003] The current steel structure connectors also have a variety of styles, but basically only one or two steel structures of the same size can be fixedly connected, and steel structures of various sizes cannot be connected on multiple planes. The connection method is very single. The scope of application is very narrow, and at the same time, th...

Problems solved by technology

[0003] The current steel structure connectors also have a variety of styles, but basically only one or two steel structures of the same size can be fixedly connected, and steel structures of various sizes cannot be connected on multiple planes. The connection method is very single. The scope of application is very narrow, and at the same time, the firmness is poor, and it is easy to lose weight and lose stability due to lateral tension. At the same time, it will disintegrate under the action of the ultimate strength. There is no buffer time and the risk is high.
