The assembly type corrugated web holding-on H shaped steel composite beam is an innovation-type composite beam which is suitable for a full assembly type steel structural system and has the advantages of saving rolled steel and being high in bearing capacity and good in stress performance compared with a traditional assembly type steel beam and a traditional composite beam.

Description

A kind of assembling corrugated web interlock H shaped steel combination beam
Technical field
The present invention relates to a kind of assembling corrugated web interlock H shaped steel combination beam, belong to the architectural shape technical field.
Background technology
The assembling type steel structure system has overcome that traditional steel house Site Welding amount is large, speed of application reaches the uppity shortcoming of construction quality slowly effectively, is the important directions of system of steel residential structure development.In the assembling type steel structure system, the on-site consolidation of Liang Heliang is a needs primary study problem.
Compare girder steel, compound beam has as follows and has superiority: can utilize the concrete pressurized effect of composite floor on girder steel, increase the effective height of beam section, improve bending rigidity and the bearing capacity of girder steel, thereby save steel and reduce cost; The steel work compound beam is compared with reinforced concrete beam and plate, can save template and reduce built-in fitting, alleviates deadweight, reduces floor height, convenient construction, and the reduction of erection time, and be convenient to install pipeline; Compound beam can be realized the full assembling of high-rise steel structure system.
In existing assembling type steel structure system, conventional composite beam usually adopts, and to be that two channel-section steel compound beams carry out assembled, and the web docking of two channel-section steels is also connected by bolt, forms assembling H shaped steel.But, in this connecting method, shearing is to pass to web by bolt, web is plain plate, and required Number of Bolts and the steel using amount of web are very large, and shear-carrying capacity has much room for improvement.
As can be seen here, it is not very desirable that traditional Steel section member is used in to effect among assembling type steel structure, not only affects the stress performance of member, and needs to consume a large amount of steel, produces unnecessary waste.So, create the novel primary structure member that is applied to the assembling type steel structure system imperative.Based on above analysis the present invention, a kind of assembling corrugated web interlock H shaped steel combination beam is proposed, this compound beam can reach and improve load bearing beam ability and saving steel double effects, purposes is more extensive, and the while can be realized large-scale industrial production, be promoted the development of full assembling type steel structure system.
Summary of the invention
The object of the invention is to propose a kind of assembling corrugated web interlock H shaped steel combination beam, its just corrugated web interlock H shaped steel replace traditional shaped steel as the girder steel in compound beam, and then provide a kind of with low cost, stress performance is superior, be applicable to the especially assembling compound beam of the how high-rise assembling type steel structure system of large span of assembling type steel structure system.
For achieving the above object, technical scheme of the present invention is a kind of assembling corrugated web interlock H shaped steel combination beam, and this compound beam is to be formed by bolts assemblies by two wave groove steel combination beams, wherein, the web interlock docking of two wave groove steel combination beams, at web, place is connected by bolt; The wave groove steel combination beam, its section shape of the mouth as one speaks is comprised of top flange, web, bottom flange, steel concrete wing plate and profiled sheet, and steel concrete wing plate, profiled sheet, top flange three fix by peg; Top flange is parallel with bottom flange, and web is vertically between top flange and bottom flange; The section of web is the ripple that even or inhomogeneous periodicity repeats, and this ripple section is rectangle waviness curve, trapezoidal waviness curve, wedge shape waviness curve or sine curve; Have bolt hole on web, for connecting bolt; Top flange and bottom flange are steel plate, and a limit parallel with web in steel plate is wavy curve, and the shape of waviness curve is identical with the ripple section configuration of web; Web is positioned over the Chu, top flange, waviness curve limit of top flange and bottom flange and the waviness curve limit of bottom flange coincide and is connected with the ripple section of web; Profiled sheet is positioned at the top, top flange, transverse reinforcement is welded in profiled sheet top, the steel concrete wing plate is positioned at the profiled sheet top, wherein in profiled sheet, steel concrete wing plate, a limit parallel with web is wavy curve, the shape of waviness curve is identical with the ripple section configuration of web, can realize being connected of steel concrete wing plate in two channel-section steel compound beams.
The rectangle waviness curve is arc chord angle rectangle waviness curve, and described trapezoidal waviness curve is the trapezoidal waviness curve of arc chord angle, and the wedge shape waviness curve is arc chord angle wedge shape waviness curve; The inclination angle of the trapezoidal oblique line section of trapezoidal waviness curve, arc chord angle rectangle waviness curve is 20 °-90 °; The inclination angle of the Wedge slant section of described wedge shape waviness curve, arc chord angle wedge shape waviness curve is 20 °--90 °; Be respectively the single face fillet weld between web and top flange and bottom flange; Web ripple density and height can change according to force request; Arc chord angle rectangle waviness curve, the trapezoidal waviness curve of arc chord angle 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.
Compare the assembling compound beam in traditional assembling type steel structure system, the present invention has following advantage:
1, the steel beam web plate after the assembling is the assembling corrugated steel, can effectively utilize the good out of plane stiffness of corrugated steel, anti-flexing supporting capacity and higher fatigue strength, the plain plate be assembled into channel-section steel is compared, in the situation that identical its shear-carrying capacity of thickness and anti-outer deformability all are significantly increased.
2, the compound beam after the assembling is the interlock shape, effectively increase the shearing bearing capacity in assembling compound beam plane, shearing in the plane of traditional assembling compound beam relies on bolt to bear and transmit, the present invention relies on the interlocking of compound beam to make whole compound beam bear the shearing in plane, effectively improve the shear resistant capacity of assembling compound beam, can guarantee a large amount of saving steels under the prerequisite of shear-carrying capacity.
3, in the assembling corrugated web interlock H shaped steel combination beam that the present invention proposes, it is relations of having optimized to a greater extent between section mechanical property and product steel using amount that section combines maximum characteristics, make it more be tending towards rationalization and scientific, and more extensive than i iron and H shaped steel combination beam purposes; The present invention adopts full automatic welding connection technology and professional positioning tooling fixture, can guarantee the accurate location between web and the edge of a wing, and seam track is consistent, easily realizes standardization, effectively enhances productivity.
