Description
Technical field
The present invention relates to a kind of assembling honeycomb web steel beam, belong to architectural shape technical field.
Background technology
At present, assembling type steel structure dwelling house system is the important directions of system of steel residential structure development.Traditional housing building of steel-structure have employed a large amount of Site Weldings when constructing, speed of application is slow, seriously polluted to environment, the most important thing is that the quality of weld seam should not control, have a strong impact on the security performance of building, assembling type steel structure system effectively overcomes the shortcoming of traditional steel house.In assembling type steel structure system, the stress performance after beam and beam on-site consolidation is a problem needing 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 hot rolling i iron, hot rolled H-shaped, the shaped steel such as welded H section steel, hot-rolled square steel pipe, welding box-shaped beam are used in assembling beam, can only be connected with the edge of a wing of bolt to beam by adopting cover plate, connect effectiveness comparison poor, the shear behavior of junction is poor, affect the holistic resistant behavior of beam, serious waste steel.
In existing assembling type steel structure system, what usually adopt is that two channel-section steels carry out assembled, and the web docking of two channel-section steels, is connected by bolt, form fabricated H profile steel.But in this connecting method, shearing passes to web by bolt, and web is plain plate, so the steel using amount of required Number of Bolts and web is very large.
As can be seen here, it is not very desirable for traditional Steel section member being used in effect among assembling type steel structure, not only affects the stress performance of component, and needs to consume a large amount of steel, produces unnecessary waste.So, create the novel primary structure member being applied to assembling type steel structure system imperative.
Summary of the invention
Based on above-mentioned defect, the present invention proposes a kind of assembling honeycomb web steel beam belonging to architectural shape technical field, object is to provide a kind of with low cost, the assembling girder steel of assembling type steel structure system that what stress performance was superior be applicable to.
Technical scheme of the present invention is as follows:
A kind of assembling honeycomb web steel beam is formed by bolts assemblies by two corrugated web steel channel beams, and two corrugated web steel channel beam web docking are connected, and carry out assembly connection at web joint by bolt.
Described corrugated web steel channel beam, its section shape of the mouth as one speaks is by top flange, and web and bottom flange composition, top flange is parallel with bottom flange, and web, vertically between top flange and bottom flange, described web has bolt hole, for connecting bolt.
The section of described web is the ripple that even or uneven periodicity repeats, this ripple section is 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 wedge shape waviness curve, or be arc chord angle wedge shape waviness curve, or be sine curve waviness curve.
Described top flange and bottom flange are plain plate, and web is overall between top flange and bottom flange, and the waviness curve outermost along its length of web 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 slant section of described wedge shape waviness curve and arc chord angle wedge shape waviness curve is 20 °--90 °.
Corrugation density and the height of described web can change according to force request.
Described web and be respectively one-side-filled angle weld between top flange and bottom flange.The present invention adopts full automatic welding connection technology and specialty aim frock clamp, can guarantee the accurate location between web and the edge of a wing, and seam track is consistent, easily realizes standardization, can realize many large-scale production, effectively enhance 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 numerical control bending technology to make, and sine curve adopts numerical control rolling techniques to make.
Beneficial effect: the present invention proposes a kind of assembling honeycomb web steel beam being applicable to assembling type steel structure system, improve the stress performance of prefabricated member, compare and the assembling girder steel in traditional assembling type steel structure system, the present invention has following advantage:
Steel beam web plate after assembling presents waviness curve type, the out of plane stiffness that can effectively utilize corrugated steel excellent, anti-flexing supporting capacity and higher fatigue strength, compared with the plain plate be assembled into channel-section steel, when thickness is identical, shear-carrying capacity and anti-outer deformability are all significantly increased.Use it for building structural steel beam can under the prerequisite ensureing shear-carrying capacity a large amount of saving steel.
Steel beam web plate after assembling is the assembling of two corrugated webs, be equivalent to double corrugated web plate, effectively can improve stability and the supporting capacity of component, especially Torsion bearing capacity, the layout of web is cellular, can obtain optimal result in the total bearing capacity of component.
Therefore, adopt assembling honeycomb web steel beam of the present invention can play above-mentioned two kinds of technical advantages simultaneously, compared with other like products, its mechanical property is significantly increased, and the thickness of the edge of a wing and web all can reduce, significantly can save rolled steel dosage, meet the overall goal of China's strategy of sustainable development.
Meanwhile, the present invention propose assembling honeycomb web steel beam in, it is optimize the relation between section mechanical property and product steel using amount to a greater extent that section combines maximum feature, make its be more tending towards rationalize and scientific.The layout of the steel beam web plate after assembling is cellular, can obtain optimal result in the total bearing capacity of component, and effective saving just now.Therefore, the present invention has the excellent stress performance such as high-bearing capacity and high rigidity, is a kind of very good structural shapes material.
Compared 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, ensures construction quality.
