Straightening device for face plate of T-shaped profile

Abstract

The invention relates to a straightening device for a face plate of a T-shaped profile. The straightening device structurally comprises a supporting plate, an intermediate connecting plate and two clamping plates. The shape of the supporting plate is in an inverted-L shape in general, and the shape of the intermediate connecting plate is in an I shape in general; two dovetail notches connected with the clamping plates are formed in the two sides of the intermediate connecting plate correspondingly; a buckle is arranged on each clamping plate, and inward bulges are further arranged at the bottoms of the clamping plates; the intermediate connecting plate are vertically welded and fixed to the inner side of the supporting plate; and the two clamping plates are embedded into the dovetail notches through the buckles, and the inward bulges on the symmetrically-distributed clamping plates are clamped on the lower surface of the face plate of the T-shaped profile in an oppositely-distributed mode. The straightening device serving as a special tool is simple in composition structure, simple in assembling and disassembling method and easy to operate, the requirement for the construction environment is low, potential safety hazards are few, and the labor hour can be saved.

Description

technical field [0001] The invention belongs to the technical field of ship and steel structure manufacturing, and in particular relates to a tooling device for correcting T-shaped bar panels. Background technique [0002] T profile is a profile commonly used in the design and manufacture of ships and steel structures. Its panel and web can be combined flexibly, and different section moduli can be provided according to needs. Due to the verticality of web and panel and the web and base metal The verticality of the verticality has different degrees of influence on the calculation of the section modulus of the T profile, so the requirements for the verticality and flatness of the T profile after assembly are relatively high. However, due to the welding effect of the fillet weld between the T-profile panel and the web, the T-profile panel will generally have a drooping deformation, and the deformed cross-sectional shape is "one". In order to meet the accuracy requirements and r...

If a temporary support is used, in addition to the need to install and disassemble the temporary support, it is also necessary to polish the temporary support, which is a waste of man-hours;

[0004] (2) Using the method of pyrotechnic correction, on the one hand, hot work will bring safety hazards, increase the safety management risk of on-site construction, and have higher requirements for the construction environment; on the other hand, pyrotechnic correction is relatively The technical ability of the construction personnel is relatively high, and the required man-hours are more, which is more complicated.
