Combined multi functional steel frame

Abstract

The invention is a combined multifunctional steel frame, comprising basic section, arch leg section, arch crown section, horizontal support frame, and beam corner connection rod or regulating tile, able to provide arch ring construction with a steel frame, able to adapt to different spans, convenient to assemble and disassemble, safe and reliable, having fewer temporary made pieces, and able to reused many times; and able to serve as the longeron of a bridging machine, the longeron of a cast-in-site bracket, the column and beam of a gantry, and the bracket of other construction equipment. And it largely enlarges the application range of the steel frame.

Description

Technical field [0001] The invention relates to a supporting device for civil engineering construction, in particular to a combined multifunctional steel frame. Background technique [0002] Arch bridges have a history of more than a thousand years in our country, and they are still the main bridge type indispensable in bridge design. Especially in the highway and municipal construction in mountainous and heavy hills, arch bridges are widely used because of their beautiful shape, convenient materials, strong spanning ability, economy and durability. However, the construction of arch bridges (mainly arch ring construction), especially the construction of long-span arch bridges, due to the backward construction ability, makes this excellent, cheap and economical bridge type often replaced by other bridge types. For the reason, the main reason is that there is no economical, safe and fast construction method and equipment for the construction of the arch ring. Many equipments used i...

Problems solved by technology

The reason is that there is not a set of economical, safe and quick construction methods and equipment for the construction of the arch ring. Many equipment used in the prior art is special-purpose, and it is difficult to play a role on other different spans and different bridge types. , resulting in a large amount of idle waste of equipment, increasing the construction cost of the arch bridge, and restricting the application range of the arch bridge

In order to overcome the deficiencies in the prior art, people have proposed a multi-purpose support device that can adapt to various civil engineering construction requirements, such as Chinese patent CN89213325.2 "multi-purpose support device" and CN91230064.7 "standing steel arch". The two pieces of patented technology can be assembled into a variety of arc arches, but due to poor integrity, insufficient rigidity and stability, low load capacity, and limited application range, it cannot be applied to the construction of long-span arch bridges.
