A kind of T-beam steel formwork manufacturing process

Abstract

The invention discloses a process for manufacturing a T beam steel formwork. The process comprises the steps of plate blanking, profile blanking, formwork manufacturing, formwork calibration, polishing and paint spraying. In the plate blanking step, formed panels in the T beam steel formwork are mainly blanked, and in the profile blanking step, channel steel in the T beam steel formwork is mainly blanked. The flatness tolerance of a formwork calibration plane is required in a way that the flatness of every 2m length of the panels is + / -1.5mm, the straightness tolerance of a panel joint at each jointing edge position is + / -1mm, the pressed edges of flanges and the panels are calibrated, and the tolerance of gaps between the flanges and the panels is 0 to 1.5mm, and is measured through a steel square. A coating standard for paint spraying is that dust, grease and water are removed from the surface of the steel formwork, the coating amount if 200g / m<2>, a standard film thickness is 40 mu m, and paint spraying on a surface contacting with concrete is required to be avoided. Compared with other steel formwork production processes, the process has the advantages that production process steps are simplified, the strength of the steel formwork is effectively strengthened, the accuracy of the steel formwork is effectively improved, and the problems of low reutilization rate, difficulty in assembly and disassembly, low construction quality and the like of the conventional steel formwork are reduced.

Description

technical field [0001] The invention relates to the field of bridge building construction, in particular to a manufacturing process of a T-beam steel formwork. Background technique [0002] Since the 1990s, my country's building structure system has made great progress. A large number of high-rise buildings and super high-rise buildings have been built, and large-scale infrastructure, urban transportation, and expressways have developed rapidly. These modern large-scale building systems require high engineering quality and complex construction techniques. [0003] A large amount of formwork is required in the bridge construction process. Due to frequent use, steel structure formwork is often used in bridge construction. Most of the lifting equipment adopts the box girder structure, so people gradually use the box girder formwork to refer to the series of bridge erecting machines. [0004] Therefore, building construction technology must be greatly improved. Similarly, new...

Problems solved by technology

Because the traditional wooden formwork for construction consumes a lot of forest resources in production and use, the recycling rate is low, it consumes a lot of material and manpower, and at the same time it causes serious harm to the environment of our country.

Traditional steel formwork has problems such as heavy weight, low reuse rate, difficult disassembly and assembly, high labor intensity for operators, and low construction quality. Combined steel formwork has disadvantages such as small blocks, many joints, and weak rigidity.
