Abstract

The utility model relates to a hot rolling H-shaped model steel. and the cross section comprises a middle part web plate and an upper wing plate and a lower wing plate connected together, the lower wing plate is normal to the web plate and the lower wing plate is extended outward to the two sides of the web plate; the upper wing plate is shaped, and the shape and the size of the upper wing plate is different from the lower wing plate. The utility model H-shaped model steel series can elementally meet the demand of the different place in construction industry, for example, utilized as a bearing girder steel or a non bearing girder steel of a construction, or utilized as a steel structure component such as a ridge or a purline, thereby, the application range of the steel frame structure construction is expanded; the steel frame construction has the advantages that the rigidity is good, the strength is high, the body is light and antiknock, the technology is simple, the construction period is short, and the production is decreased, as well as the development of the construction industry is promoted.

Description

Hot rolling abnormity H shaped steel

Technical field

The utility model step and section bar for building, specifically a kind of hot rolling abnormity H shaped steel.

Background technology

Advantages such as modern architecture is extensive use of steel framed structure, and the building of this structure has good rigidity, intensity height than the concrete structure, and body is light, antidetonation, can build super high rise building, and construction technology is simple, and speed of application is fast, the duration is short.But steel framed structure uses maximum its section shape of the mouth as one speaks of section bar to be the equilateral H shape in both sides in the prior art, and kind is single, can not satisfy the needs of the various different occasions of builing industry, and prior art has improves perfect necessity, increases new steel section bar kind.

Summary of the invention

The purpose of this utility model provides the series of products of hot rolling abnormity H shaped steel, satisfies the needs of the various different occasions of builing industry.

The purpose of this utility model is achieved in that

A kind of hot rolling abnormity H shaped steel, its section shape of the mouth as one speaks is made of central-web and last lower wing plate disjunctor, it is characterized in that:

Its lower wing plate and this lower wing plate vertical with web equidistantly stretches out to the web both sides;

It is special-shaped and inequality with the shape and the size of lower wing plate that its upper flange is.

The upper and lower wing plate of the described section shape of the mouth as one speaks is parallel, its upper flange be shorter in length than lower wing plate, this upper flange vertically equidistantly stretches out to the web both sides.

The upper and lower wing plate of the described section shape of the mouth as one speaks is parallel, and its upper flange is the long right short shape in a left side.

The relative web of upper flange in the described section shape of the mouth as one speaks α that tilts to have angle.

Upper flange in the described section shape of the mouth as one speaks is equilateral herringbone, intersects its angle of cut β＜90 ° with its mid point and web isogonism.

Upper flange in the described section shape of the mouth as one speaks vertically stretches out to web is one-sided.

The angle α of the relative web of described upper flange and the value of β are between 45 ° of 10 ° of ∽.

The thickness of the upper and lower wing plate in the described section shape of the mouth as one speaks is greater than the thickness of web.

The upper and lower wing plate in the described section shape of the mouth as one speaks and the junction of web have the required circular arc of hot rolling technology excessive.

The utility model has following actively useful effect:

Hot rolling abnormity H shaped steel series of products of the present utility model can satisfy the needs of builing industry different places substantially, and for example the type of Fig. 1, Fig. 2 is applicable to and makes building load-bearing girder steel, non-bearing girder steel; The type of Fig. 3, Fig. 4, Fig. 5 is applicable to that building makes ridge, steel structure members such as wingceltis bar, thus expanded steel framed structure architectural applications scope; The good rigidity of bringing into play steel framed building better and being had, intensity height, body are light, antidetonation, technology is simple, the duration is short, reduce advantages such as cost, the development of promotion builing industry.

Specific embodiment

The utility model is a kind of series of products of hot rolling abnormity H shaped steel, and its section shape of the mouth as one speaks is made of central-web 1 and last

lower wing plate

2,3 disjunctors, it is characterized in that:

Its lower wing plate equidistantly stretches out to web 1 both sides with web 2 vertical 1 and this lower wing plate 2;

It is special-shaped and inequality with the shape and the size of lower wing plate 2 that its upper flange 3 is.

In the embodiment shown in fig. 1, the upper and

lower wing plate

3,2 of the described section shape of the mouth as one speaks is parallel, its upper flange 3 be shorter in length than lower wing plate 2, this upper flange 3 vertically equidistantly stretches out to web 1 both sides.

In embodiment illustrated in fig. 2, the upper and

lower wing plate

3,2 of the described section shape of the mouth as one speaks is parallel, and its upper flange 3 is the long right short shape in a left side.

In the embodiment shown in fig. 3, the relative webs 1 of the upper flange in the described section shape of the mouth as one speaks 3 α that tilts to have angle.

In the embodiment shown in fig. 4, the upper flange 3 in the described section shape of the mouth as one speaks is equilateral herringbone, intersects its angle of cut β＜90 ° with its mid point and web 1 isogonism.

In the embodiment shown in fig. 5, the upper flange 3 in the described section shape of the mouth as one speaks vertically stretches out to web 1 is one-sided.

During enforcement, the angle α of described upper flange 3 relative webs 1 and the value of β are between 45 ° of 10 ° of ∽.
