A steel structure fastener that can be firmly connected

Abstract

The invention discloses a steel structure fastener capable of realizing firm connection. The steel structure fastener comprises two fixing plates, first inserting rods are fixed to the faces, close to the inner sides, of the two fixing plates, the first inserting rods are arranged at the two ends of the same side face of the fixing plates, the bottoms of the first inserting rods are each of a two-half structure, the two fixing plates are fixed through bolts, protruding blocks are arranged at the bottoms of the fixing plates, the fixing plates are connected to the two sides of a steel structure in an inserted mode through the first inserting rods, the steel structure is provided with first pin holes matched with the first inserting rods, circular truncated cone grooves are formed in the bottoms of the first pin holes, and tip cones are placed in placement grooves. When the steel structure fastener is mounted, through the arranged first inserting rods and the formed first pin holes, first locking blocks slidably arranged at the bottoms of the first inserting rods are jacked up by the tip cones to slide towards the two sides, the first inserting rods and the first pin holes are locked and not separated, mounting is firm and reliable, and automatic locking is achieved so that separation can be avoided.

Description

technical field [0001] The invention relates to the technical field of steel structure fasteners, in particular to a steel structure fastener capable of stable connection. Background technique [0002] Steel structure is a structure composed of steel, which is 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. Because of its light weight and simple construction, Widely used in large factories, venues, super high-rises and other fields. Due to the different structures of the buildings or the large spans, it is impossible to produce a suitable overall structure for installation. This requires splicing and combining different steel structures to complete the required building structure. , so the long-term stability of the connection part is required to avoid the problem of tripping. In the prior art, when the steel structure is connected, the con...
