Embodiment 1
[0020] A corrugated plate steel beam bent in the plane direction, including a flange plate 1, a corrugated steel plate 2, and a stiffening plate 3, the flange plate 1 is located at the top or bottom of the corrugated steel plate 2; The top view of the flange plate 1 after horizontal sectioning is arc-shaped, and the arc and arc direction of the flange plate 1 and the corrugated steel plate 2 are consistent; the corrugated steel plate 2 and the flange plate 1 are welded and connected.
[0021] The stiffening steel plate 3 is welded to the corrugated steel plate 2 or / and the flange plate 1 .
[0022] The corrugated steel plate 2 has a convex or concave arc shape in the horizontal direction.
[0023] The number of stiffening steel plates 3 is more than two, and the number of corrugated steel plates 2 is more than one.
[0024] The stiffened steel plate 3 adopts a corrugated plate or a T-shaped plate, and the planes of the stiffened steel plate are not completely parallel.
Embodiment 2
[0026] The manufacturing process of the corrugated plate steel girder bent in the plane direction includes the following steps:
[0027] a. Typesetting of steel plate raw materials;
[0028] b. CNC cutting and blanking;
[0029] c. The corrugated steel plate 2 is rolled and formed;
[0030] d. Secondary forming of the corrugated steel plate 2 in the horizontal direction;
[0031] e. The corrugated steel plate 2 is assembled with the flange plate 1;
[0032] f. The flange plate 1 and the stiffening steel plate 3 are welded to the corrugated steel plate 2 respectively.
[0033] The method of CNC cutting and blanking is CNC zigzag cutting; the corrugated steel plate 2 adopts the wave-band step-by-step forming method.
[0034] The amplitude of the step-shaping is equal to the unfolded length of a unit wave.
[0035] The welding sequence of the flange plate 1 and the corrugated steel plate 2 is from both sides to the middle. The welding process takes the wave length as the wel...

Abstract
The invention relates to a planar-bending corrugated sheet steel beam. The planar-bending corrugated plate steel beam comprises a flange sheet, a corrugated steel sheet and a stiffened steel sheet, and the flange sheet is positioned at the top or bottom of the corrugated steel sheet; after the corrugated steel sheet is horizontally sectioned, the top view of the corrugated steel sheet is arc-shaped; after the flange sheet is horizontally sectioned, the top view of the flange sheet is arc-shaped, and the radian and the arc-shaped direction of the flange sheet are consistent to the radian and the arc-shaped direction of the corrugated steel sheet; and the corrugated steel sheet is in welding connection with the flange sheet. The planar-bending corrugated sheet steel beam has the characteristics of unified and beautiful profile, low cost and convenient production. More importantly, the planar-bending corrugated sheet steel beam is suitable for special structures comprising steel beams, enclosure walls, guardrails and the like satisfying convex surface building exterior walls of engineering buildings, has a beautiful overall structure and is practical. The planar-bending corrugated sheet steel beam satisfies the structure needs, also satisfies the building profile needs, allows subsequent decorations to be constructed along the profile of the corrugated sheet steel beam, and becomes a structure, building and decoration integrated economic member.
Description
technical field [0001] The invention relates to a corrugated plate steel beam and a manufacturing process, in particular to a corrugated plate steel beam bent in a plane direction and a manufacturing process. Background technique [0002] With the continuous development of engineering structures in our country, new forms of steel structures are emerging, and corrugated steel structures have been widely used. Corrugated steel girders are generally made into straight steel girders because of their waveform characteristics. Straight steel girders cannot meet some special structures in the relevant requirements of engineering building shapes, such as steel girders, fences, and guardrails on the exterior walls of convex buildings. Wait. Contents of the invention [0003] The present invention is proposed to solve the deficiencies of the existing corrugated steel girders that cannot meet the special structures of steel girders, enclosure walls, guardrails and other special stru...
