preparation example Construction

[0069] The present invention provides following two kinds of feasible preparation techniques:

[0070] The preparation method of the first novel steel structure comprises the following steps:

[0071] (1) Cutting plate-shaped substrates:

[0072] The plate-shaped base material is a flat steel material such as a steel plate or a flat steel, or the plate-shaped base material is a flat steel material obtained by straightening and slitting a wide-band steel, or, the plate-shaped base material is Different diameter steel plate or different diameter flat steel.

[0073] cutting transversely along the cutting line on the plate-shaped base material to obtain a first plate body and a second plate body interlocking with each other;

[0074] Wherein, the first plate body is formed with a plurality of first protrusions arranged at intervals at the cutting position, and a first concave portion is formed between any two adjacent first protrusions; the second plate body is cut A plurality...

Embodiment 1

[0089] Such as Figure 1 to Figure 10 Shown, the preferred structure of a kind of novel just structure described in the present invention.

[0090] Such as Figure 4 As shown, the novel steel structure described in this embodiment is an I-shaped steel with an I-shaped cross section. The novel rigid structure includes a web 40 and flanges 50 located at both ends of the web 40 . The web 40 is a hollowed out long straight steel plate.

[0091] In one embodiment, the flange 50 and the web 40 are integrally formed by a rolling process; in another embodiment, the flange 50 and the web 40 are connected by welding.

[0092] Specifically, the web 40 is a combined steel plate, and the web 40 includes a first plate body 11 and a second plate body 21 that can be engaged with each other, and the first plate body 11 and the second plate body 21 are welded to form a long straight plate .

[0093] Such as figure 2 As shown, the first plate body 11 has a plurality of first protrusions 1...

Embodiment 2

[0148] A new type of steel structure and its preparation method in this embodiment 2 are consistent with the structure and method of embodiment 1, and this embodiment 2 provides a preferred structural size of a new type of steel structure.

[0149] Such as Figure 11 As shown, the top length L1 of the first convex portion and the second convex portion of the web is 100 mm to 200 mm. Under this structural dimension, the length of the contact surface between the first convex part and the second convex part is 100 mm to 200 mm. Correspondingly, the root length L2 of the first convex portion and the second convex portion is 120mm˜200mm.

[0150] Preferably, the length L1 of the top of the first protrusion and the second protrusion is 100 mm or 120 mm.

[0151] Such as Figure 11 As shown, the heights H1 of the first convex portion and the second convex portion are both 100 mm to 200 mm. Preferably, the height H2 of the first convex portion and the second convex portion are bot...

Abstract

The invention discloses a preparation method of a novel steel structure. The method comprises the following steps of (1) cutting a base material, wherein the base material is provided with a web, theweb of the base material is transversely cut along a cutting line to obtain a first sub-body and a second sub-body which can mutually engage with each other along the cutting position of the web, a plurality of first convex parts which are arranged at intervals at the cutting position of the web are formed at the first sub-body, a first concave part is formed between any two adjacent first convexparts, a plurality of second convex parts which are arranged at intervals at the cutting position of the web are formed at the second sub-body, and a second concave part is formed between any two adjacent second convex parts; and (2) welding the novel steel structure, specifically, the first sub-body is turned over, the positions of the plurality of first convex parts and the positions of the plurality of second convex parts are opposite to each other, the first convex parts and the second convex parts are welded for connection to obtain the base material with a hollow-out web, the novel steelstructure is obtained, and the web of the novel steel structure is straightened through mechanical equipment.

Description

technical field [0001] The invention belongs to the technical field of steel materials, and in particular relates to a novel steel structure and a preparation method thereof. Background technique [0002] Sectional steel is a strip steel with a certain cross-sectional shape and size, including I-beam, H-shaped steel, channel steel, angle steel, square rectangular tube, etc. Sectional steel is widely used in various building structures, such as steel frame bridges, beams and columns Wait. [0003] In the process of realizing the invention, the applicant found the following problems in the existing part of complex section steel: [0004] Existing section steel is mostly prepared by welding or rolling process, such as I-beam / H-beam in section steel, I-beam using hot rolling process is generally used to make small-span beams; It is often used to make beams with large spans. However, the web of the existing I-beam / H-beam is a complete steel plate, and when it is used in a stru...
