Plug-in steel truss joint construction for building bridges or building structures

Abstract

An inserted-type steel truss joint construction comprises a steel truss joint, truss frame rod parts, fasteners, structural adhesives and bolts, wherein at least one be-inserted opening is formed in the steel truss joint, and a be-inserted end flange is arranged at the end of each be-inserted opening; each truss frame rod part is provided with an inserting end which can be in clearance fit with the be-inserted end of the steel truss joint, wherein an inserting end flange is arranged on the tail, opposite to the end of the truss frame rod part, of the inserting end; each fastener is composed of two half parts, a groove is formed in each fastener, and each groove is matched with the peripheries of the corresponding be-inserted end flange and the corresponding inserting end flange, upper half bosses are arranged at the two ends of a closing line of the first half parts of the fasteners, and upper half bolt holes are formed in each upper half boss, while a lower half bosses is arranged at the two ends of a closing line of the second half parts of the fasteners, and lower half bolt holes are arranged on the lower half bosses; structural adhesives are arranged in installing clearances; and the bolts enable the upper half bolt holes to be connected with the lower half bolt holes. The truss frame joint construction is high in construction efficiency, good in reliability, and long in service life.

Description

technical field [0001] The invention relates to a plug-in steel truss node structure for building bridges or building structures, which can shorten the construction period and belongs to the fields of bridge engineering and building engineering. [0002] The plug-in steel truss node according to the present invention can be a prefabricated part, or a welded or assembled part on site. Background technique [0003] In the prior art, general truss joints in bridges and building structures are formed by riveting, welding and connecting high-strength bolts and rods. With the development of welding technology and high-strength bolt connection technology, traditional riveting technology has been gradually eliminated due to the difficulty of on-site construction. Welding and high-strength bolt connections have greatly improved the connection reliability of nodes and rods, and more and more engineering examples have shown that welding can easily lead to changes in the metallographic...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, structural adhesives are widely used in engineering practice, but their durability is the key factor affecting the reliability of the connection

[0005] In the existing technology, those skilled in the art have formed the inertia of traditional thinking such as steel truss welding or high-strength bolt connection, and it is difficult to break through technical prejudices, and it is even more difficult to think of new bridges that are convenient for construction and meet various mechanical properties. or building structure node construction
