Description

Technical Field

[0001] The utility model belongs to the technical field of building steel structure construction equipment, in particular to an auxiliary installation device for a steel structure arc stiffening plate. Background Art

[0002] In the construction of steel structure frames, steel components are prone to flexural deformation when subjected to vertical loads, resulting in failure of the steel components. In order to improve the strength of the steel components, stiffening plates need to be added to the steel components. In particular, when processing some curved steel structure top plates, it is necessary to weld curved stiffening plates on the top plates to ensure the strength of the top plates; when installing and welding the curved stiffening plates of steel structures, the stiffening plates are processed according to the arc shape, but the steel plates are large in size and deformed greatly, so the stiffening plates and steel plates cannot be completely fitted during installation and welding, and repeated adjustments are required; when the curved stiffening plates are welded on site, the welders manually position and weld them, which is prone to deformation or position deviation. Manual adjustment is time-consuming and labor-intensive, and is prone to quality problems. The construction quality cannot be guaranteed, and the first-time pass rate requirement cannot be met.

[0003] In the application number 201720883892.3, a steel structure stiffening plate assembly auxiliary device is disclosed, including a panel, a bolt hole is provided on the panel, two panels are bolted together by bolts, a strong magnet is fixedly provided on the inner surface of the panel, the strong magnet is distributed on the edge of the panel, and a strong magnetic corner plate is fixedly provided at the corner of the panel to protect the strong magnetic corner plate. The strong magnet is distributed on the inner surface of the panel near one end and the bottom end of the stiffening plate. A hand-held hole is provided on the panel, and the shape of the hand-held hole is semicircular. The angle a between the side of the panel near the stiffening plate and the bottom surface of the panel can be an acute angle, a right angle or an obtuse angle. However, when the device is used, it mainly uses adhesive strong magnets to fix the stiffening plate by magnetic attraction. The fixing method is single, and it cannot fix stiffening plates of different models and sizes. In addition, the adhesive method is not durable and is easy to fall off after long-term use, which affects the construction efficiency and brings inconvenience to the operator. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an auxiliary installation device for arc-shaped stiffening plates of steel structures, which solves the problems that the existing stiffening plate auxiliary devices have a single fixing method and are easy to fall off after long-term use, affecting construction efficiency and causing inconvenience to operators.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By means of the installation auxiliary device arranged on the arc-shaped stiffening plate, the vertical plate surface of the arc-shaped stiffening plate can be positioned and fixed in the horizontal direction by means of the arranged positioning groove, positioning bolt A and positioning bolt B, and the horizontal plate surface of the arc-shaped stiffening plate can be fixed and positioned in the vertical direction by means of the arranged pressing component; thereby, the stiffening plate is fixed to the surface of the steel member, and displacement of the stiffening plate during welding is avoided; the auxiliary device has a simple structure, is convenient for long-term use, and has a good fixing and positioning effect, and can quickly adjust the deformation of the steel plate, so that the stiffening plate fits the steel plate, is easy to weld, and ensures construction efficiency.
