Highly-thrust-resistant pin structure for connecting constructional steel column with constructional steel pipe truss

Abstract

The invention discloses a highly-thrust-resistant pin structure for connecting a constructional steel column with a constructional steel pipe truss. The highly-thrust-resistant pin structure comprises a pin, a truss node and a pin connecting seat, the truss node is integrally formed by casting, the truss node and the constructional steel pipe truss are welded mutually, the pin connecting seat is fixedly connected with the constructional steel column, the truss node and the pin connecting seat are of mutually folded lug plate butting structures and are provided with pin holes for the pin to penetrate through, and after the truss node and the pin connecting seat are folded, the pin is inserted into the pin holes to hinge the truss node and the pin connecting seat integrally, so that integrity and thrust-resistant rigidity of the pin structure are enhanced. The constructional steel pipe truss is in swing connection with the constructional steel column through the pin structure. The pin structure is capable of achieving swing connection of the constructional steel pipe truss with the constructional steel column and has the advantages of high thrust-resistant rigidity, good integrity, attractive appearance and more stable and reliable connection and force transfer.

Description

technical field [0001] The invention relates to a connection mechanism in the construction industry, in particular to a large anti-thrust pin shaft structure used to connect building steel columns and steel pipe trusses, and is used for the swing connection between steel columns and steel pipe truss nodes. Background technique [0002] At present, in the field of building structures, the pin connection is usually used as the swing connection between the steel column and the steel pipe truss node. The pin connection is a connecting part that transmits force through the lug plate and the cylindrical pin. Free rotation, eliminating the adverse effect of stress concentration caused by the fixed connection between the steel pipe truss and the steel column. [0003] Conventional pin connection structures used in building structures such as figure 1 , figure 2 As shown, the pin connection structure includes a forged steel rod 103, an upper ear plate 104, a lower ear plate 105 an...

AI Technical Summary

Problems solved by technology

In the prior art, the conventional pin connection adopts the welded lug technology. Because the thickness of the lug is thin and it is difficult to strengthen it in the axial direction, the axial thrust bearing capacity of the pin connection is small, and it can only be applied to The axial thrust in the axial direction of the pin shaft, or the connection with a small axial thrust, has poor integrity and cannot be used for connections with a large axial thrust, so its use is limited and has certain safety hazards
