Description

Assembling honeycombed web girder steel

Technical field

The present invention relates to a kind of assembling honeycombed web girder steel, belong to the architectural shape technical field.

Background technology

At present, the assembling type steel structure dwelling house system is the important directions of system of steel residential structure development.Traditional housing building of steel-structure has adopted a large amount of scene welding when constructing, speed of application is slow, and seriously polluted to environment the most important thing is that the quality of weld seam should not be controlled, have a strong impact on the security performance of building, the assembling type steel structure system has overcome the shortcoming of traditional steel house effectively.In the assembling type steel structure system, the stress performance behind beam and the beam on-site consolidation is a problem that needs primary study.

The section steel beam that can adopt in similar field comprises hot rolling i iron, hot rolled H-shaped, welded H section steel, hot-rolled square steel pipe, welding box-shaped beam and channel-section steel etc.

When shaped steel such as hot rolling i iron, hot rolled H-shaped, welded H section steel, hot-rolled square steel pipe, welding box-shaped beam are used in the assembling beam, can only be connected with the edge of a wing of bolt to beam by adopting cover plate, it is poor to connect effect, the shear behavior of junction is relatively poor, influence the holistic resistant behavior of beam, the serious waste steel.

In existing assembling type steel structure system, what adopt usually is that two channel-section steels carry out assembly unit, and the web butt joint of two channel-section steels connects by bolt, forms fabricated H shaped steel.But in this connecting method, shearing is to pass to web by bolt, and web is plain plate, so the steel using amount of required bolt number and web is very big.

This shows, traditional Steel section member is used in effect is not very desirable among the assembling type steel structure, not only influence the stress performance of member, and need to consume a large amount of steel, produce unnecessary waste.So it is imperative to create the novel primary structure member that is applied to the assembling type steel structure system.

Summary of the invention

Based on above-mentioned defective, the present invention proposes a kind of assembling honeycombed web girder steel that belongs to the architectural shape technical field, it is a kind of with low cost that purpose is to provide, the assembling girder steel of the assembling type steel structure system that is applicable to that stress performance is superior.

Technical scheme of the present invention is as follows:

A kind of assembling honeycombed web girder steel is to be formed by bolts assemblies by two corrugated web steel channel beams, and two corrugated web steel channel beam web butt joints link to each other, and assemble connection at the web joint by bolt.

Described corrugated web steel channel beam, its section shape of the mouth as one speaks are by the top flange, and web and bottom flange are formed, and the top flange is parallel with the bottom flange, and web vertically between top flange and bottom flange, has bolt hole on the described web, are used for connecting bolt.

The section of described web is the ripple that even or inhomogeneous periodicity repeats, this ripple section is the rectangle waviness curve, or be arc chord angle rectangle waviness curve, or be trapezoidal waviness curve, or be the trapezoidal waviness curve of arc chord angle, or be the wedge shape waviness curve, or be arc chord angle wedge shape waviness curve, or be the sine curve waviness curve.

Described top flange and bottom flange are plain plate, and web integral body is between top flange and bottom flange, and the waviness curve of web outermost along its length flushes with top flange and a sideline along its length, bottom flange.

The inclination angle of the trapezoidal oblique line section of described trapezoidal waviness curve and the trapezoidal waviness curve of arc chord angle is 20 °--90 °.The inclination angle of the wedge shape oblique line section of described wedge shape waviness curve and arc chord angle wedge shape waviness curve is 20 °--90 °.

The ripple density of described web and height can change according to force request.

Be respectively the single face fillet weld between described web and top flange and the bottom flange.The present invention adopts full automatic welding connection technology and professional positioning tool anchor clamps, can guarantee the accurate location between web and the edge of a wing, and the seam track unanimity realizes standardization easily, can realize many large-scale production, effectively enhances productivity.

The trapezoidal waviness curve of described arc chord angle, arc chord angle rectangle waviness curve and arc chord angle wedge shape waviness curve adopt the numerical control bending technology to make, and sine curve adopts numerical control roll-in technology to make.

Beneficial effect: the present invention proposes a kind of assembling honeycombed web girder steel that is applicable to the assembling type steel structure system, improved the stress performance of prefabricated member, compare with traditional assembling type steel structure system in the assembling girder steel, the present invention has following advantage:

Steel beam web plate after the assembling is to present the waviness curve type, can effectively utilize rigidity outside the good plane of corrugated steel, anti-flexing supporting capacity and higher fatigue strength, compare with the plain plate that channel-section steel is assembled into, under the identical situation of thickness, shear-carrying capacity and anti-outer deformability all are significantly increased.Use it for the building structural steel beam and can under the prerequisite that guarantees shear-carrying capacity, save steel in a large number.

Steel beam web plate after the assembling is the assembling of two corrugated webs, be equivalent to double corrugated web plate, can improve stability and the supporting capacity of member effectively, especially antitorque bearing capacity, the layout of web is cellular, can obtain optimal result aspect the total bearing capacity of member.

Therefore, adopt assembling honeycombed web girder steel of the present invention can bring into play above-mentioned two kinds of technical advantages simultaneously, compare with other like products, its mechanical property is significantly increased, and the thickness of the edge of a wing and web all can reduce, can significantly save rolled steel dosage, meet the overall goal of China's strategy of sustainable development.

Simultaneously, in the assembling honeycombed web girder steel that the present invention proposes, it is relations of having optimized to a greater extent between section mechanical property and the product steel using amount that section makes up maximum characteristics, makes it more be tending towards rationalization and scientific.The layout of the steel beam web plate after the assembling is cellular, can obtain optimal result aspect the total bearing capacity of member, effectively saves just now.Therefore, the present invention has good stress performances such as high-bearing capacity and high rigidity, is a kind of very good structural shapes material.

Compare with traditional assembling girder steel, the present invention can improve the supporting capacity of girder steel significantly, reduces steel using amount, reduces construction costs, can realize large-scale industrial production and on-the-spot quick assembled type simultaneously, reduces construction period, guarantees construction quality.
