Construction method of siphon water pipe in a fish-bellied inclined concrete steel pipe column

Abstract

The invention relates to a construction method for siphon pipe inside fish-bellied inclined concrete-filled steel tube column, specifically comprising the steps of design development phase; factory prefabricating phase; steel column installation phase; the phase of welding siphon pipe and carrying out flushing test; casting of concrete inside and outside column. The invention can precisely, quickly, easily and safely implement the installation of siphon pipe.

Description

technical field [0001] The invention relates to a construction method of a siphon water pipe, in particular to a construction method of a siphon water pipe in a fish-bellied inclined concrete steel pipe column. Background technique [0002] With the development of architectural design concepts, steel columns are not only used as the support of the main structure, but also designed as fish-belly inclined installations according to the shape requirements, and the previously exposed equipment and pipes are arranged in the columns, which can beautify the building while meeting the design requirements. The effect of appearance. During the construction of the steel structure, not only the prestressed perforation and civil steel reinforcement perforation must be considered, but also the equipment and pipelines must be installed in the steel pipe column, and the construction space must be reserved for the location of the siphon water pipe. The connection of the siphon water pipes c...

AI Technical Summary

Problems solved by technology

For the inclined fish-belly steel column, there are the following problems: the joints of the steel column are complicated, and there are many factors affected, and the siphon water pipe cannot be arranged in the middle; bit; the design requires rigid connections, socket connections are not allowed, and expansion cement seals

For the inclined fish-belly steel column, there are the following problems: the weight of the steel column is heavy, and it is supported by splints, which is not strong enough and dangerous; the lifting of the steel column is difficult

The fish-belly inclined steel column adopts this method for docking, because the guide rail cannot be accurately guided during the construction of the inclined steel column, it needs to be in place when the truck crane is hoisted, and the steel column needs to be lowered along a certain angle, which makes the construction difficult. The adjustable range of the siphon water pipe in the center is small, a slight deviation will lead to damage to the siphon water pipe, and the siphon effect in the urban area will also cause the siphon water to accumulate in the column and corrode the steel column
