Problems solved by technology

[0002] At present, it is usually processed and bent in the factory. On the construction site, under special construction conditions, some thin-walled steel pipes with special angles need to be bent according to actual needs, but the wall thickness of thin-walled steel pipes is thin and easy to deform.

Embodiment 1

[0028] A kind of simple and easy cold-bending method of thin-walled steel pipe of the present embodiment, its steps are:

[0029] 1) Set the bottom plate:

[0030] Place a steel bottom plate 2 on the construction site, and use a level to level the bottom plate 2. The unevenness of the bottom plate 2 is: no more than 1mm per meter. Bending requirements or drawing size of thin-walled steel pipe 1: According to the bending angle of thin-walled steel pipe 1, the angle section of thin-walled steel pipe 1 is divided into three sections from left to right on the bottom plate 2 (ie, the angle section of the left section , middle section angle section, right section angle section) (referred to as left section, middle section, right section) and corresponding to the end face or interface of left section, middle section, right section angle section respectively lead out the rays of the same circle center;

[0031] 2) Thin-walled steel pipe filled with fine sand:

[0032] A considerable...

Abstract

The invention discloses a simple cold bending method for a thin-wall steel pipe, and belongs to the technical field of building construction. The method comprises the steps of: 1) arranging a bottom plate; 2) filling a thin-wall steel pipe with fine sand; 3) preparing a positioning combination device and a machine tool for cold bending of the thin-wall steel pipe; 4), arranging the thin-wall steel pipe; and 5) carrying out cold bending on the thin-wall steel pipe. According to the method, a jack, the fine sand and the positioning combination device for the thin-wall steel pipe are adopted for cold bending of the steel pipe, so that the method is convenient to operate, safe and reliable to use and high in applicability, the construction cost and unsafe factors are reduced, and the construction quality and the construction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a simple cold bending method for thin-walled steel pipes. Background technique [0002] At present, it is usually processed and bent in the factory. On the construction site, under special construction conditions, some thin-walled steel pipes with special angles need to be bent according to actual needs, but the wall thickness of thin-walled steel pipes is thin and easy to deform. ; and the limitation of the space environment in the construction site, it takes a lot of manpower and material resources to bend, and the cycle is long, which often affects the next step of the process, increases the labor intensity of the construction personnel, and also has potential safety hazards. Contents of the invention [0003] 1. Problems to be solved [0004] Aiming at the defects and deficiencies existing in the prior art, the present invention provides a simple cold-bending...
