[0033] refer to Figure 1 to Figure 6 As shown, the present invention provides a folded plate bent and twisted corbel installed on the steel column 6, and the folded plate bent and twisted corbel is a variable section corbel. The folded plate bending corbel includes: an upper flange folded plate 1, a lower flange folded plate 2 and a web folded plate 3 connected between the two sides of the upper flange folded plate 1 and the lower flange folded plate 2. The upper flange flap 1, the lower flange flap 2 and the web flap 3 are all quadrangular. The upper flange flap 1 , the lower flange flap 2 and the web flap 3 are respectively bent along their own diagonals to form a bending-resistant back 71 .

[0034] The bent and twisted corbel of the present invention is processed by the folding method, and the upper flange folded plate, the lower flange folded plate and the belly folded plate of the folded plate bent and twisted corbel of the present invention only need to be folded duri...

[0072] Figure 7 It is a structural schematic diagram of the third stiffening plate of the twisted corbel of the folded plate of the present invention.

[0073] The difference between this embodiment and the first embodiment lies in: the specific structure of the stiffening structure, and other differences will not be repeated here.

[0074] Specifically, in this embodiment, the stiffening structure includes a third stiffening plate 53 . The third stiffener 53 is connected between the upper flange flap 1 , the lower flange flap 2 and the web flap 3 . The third stiffener 53 is arranged obliquely between the upper flange flap 1 and the lower flange flap 2 . The third stiffener passes through the bending spine of the upper flange flap, lower flange flap and web flap, and the bending spine of the third stiffener and the upper flange flap, lower flange flap, and web flap Angled set.

[0075] Through holes are formed in the third stiffening plate 53 .

Abstract

The invention provides a folded-plate bending-and-twisting bracket and a manufacturing method thereof. The folded-plate bending-and-twisting bracket comprises an upper flange folded plate, a lower flange folded plate and a bent web, wherein the bent web is connected between the two sides of the upper flange folded plate and the lower flange folded plate. The upper flange folded plate, the lower flange folded plate and the bent web are all in a quadrangular shape. The upper flange folded plate, the lower flange folded plate and the bent web are separately bent along a pair of own diagonal linesto form anti-bending backs. The problems of long processing cycle and affected structural safety of components caused by using a traditional double-parabolic slab processing method or a triangular jointed-board processing method to process folded-plate bending-and-twisting brackets are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a bent and twisted corbel of a folded plate and a manufacturing method thereof. Background technique [0002] It is very difficult to deepen the lofting and processing of the traditional bent and twisted corbels. The single plate of the corbel mainly adopts the hyperbolic plate processing method or the triangular imposition processing method. In order to achieve the hyperbolic effect of the hyperbolic plate method, a single plate needs to be rolled and corrected multiple times, and the processing cycle is long; on the other hand, the single plate processed by the hyperbolic plate method is welded and assembled into a corbel. The residual deformation produced by the welding seam is likely to cause a large change in the shape of the corbel. The triangular imposition method needs to weld multiple small plates to form a corbel. There are a large number of connecting we...
