Description

A kind of assembling honeycombed web combination beam
Technical field
The present invention relates to a kind of assembling honeycombed web combination beam, 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.During the construction of tradition housing building of steel-structure, owing to adopting a large amount of Site Weldings, cause the problems such as speed of application is slow, environment pollution is serious and weldquality to control, these security performances to building cause very big hidden danger.The assembling type steel structure system can overcome traditional steel house shortcoming well, and therefore in this system, the mechanical property after compound beam and compound beam on-site consolidation is a needs primary study problem.
In existing assembling type steel structure system, usually adopt to be that two channel-section steels carry out assembled, the web docking of two channel-section steels, connected by bolt, forms fabricated H shaped steel.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., these shaped steel are in assembling compound beam member the time, can only with the edge of a wing of bolt to beam, be connected by cover plate, the connection effect is poor and shear behavior junction is also poor.Yet in this connected mode, shearing is to pass to web by bolt, and web is generally plain plate, so required Number of Bolts and web steel using amount are very large.
As can be seen here, traditional Steel section member be used in assembling type steel structure among effect unsatisfactory, it not only affects the stress performance of member, and need to consume great deal of steel.Therefore imperative for the novel primary structure member innovation research of assembling type steel structure system, the present invention is based on above reason and propose a kind of assembling honeycombed web combination beam, research and discussion replace traditional shaped steel as the girder steel in compound beam with assembling honeycombed web combination beam, and then be applied to the multi-rise building field, realize the purpose that reduces costs, optimizes mechanical property and increase the service life.
Summary of the invention
The object of the present invention is to provide a kind of assembling honeycombed web combination beam, this compound beam is with low cost and mechanical property is superior, is applicable to the assembling type steel structure system.
For achieving the above object, the technical solution used in the present invention is a kind of assembling honeycombed web combination beam, this compound 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 at the web joint, by bolt, carry out assembly connection.
The section shape of the mouth as one speaks of corrugated web groove compound beam is comprised of steel concrete wing plate, profiled sheet, top flange, web and bottom flange, and top flange is parallel with bottom flange, and web is vertically between top flange and bottom flange; Have bolt hole on web, for connecting bolt; The steel concrete wing plate is positioned at the profiled sheet top, and profiled sheet is positioned at the top, top flange; Steel concrete wing plate, profiled sheet, top flange three fix by peg; Peg can be used as shear connector steel concrete wing plate, profiled sheet, girder steel top flange is connected into to integral body, and transverse reinforcement is welded in profiled sheet top.
The web section is even or inhomogeneous periodicity and repeats ripple, 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; The inclination angle of the trapezoidal oblique line section of trapezoidal waviness curve and the trapezoidal waviness curve of arc chord angle is 20 °-90 °; The inclination angle of the Wedge slant section of wedge shape waviness curve and arc chord angle wedge shape waviness curve is 20 °-90 °; Web ripple density and height can change according to force request; The trapezoidal waviness curve of 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.
Top flange and bottom flange are plain plate, and web integral body is between top flange and bottom flange, and web waviness curve outermost along its length flushes with top flange and a sideline along its length, bottom flange; Be respectively the single face fillet weld between web and top flange and bottom flange, the present invention simultaneously adopts full automatic welding connection technology and professional positioning tooling fixture, guarantees the accurate location between web and the edge of a wing, and seam track is consistent.
With traditional assembling compound beam, compare, the present invention has the following advantages:
1, the compound beam web after the present invention's assembling presents the waviness curve type, 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 thickness is identical, shear-carrying capacity and anti-outer deformability all are significantly increased.
2, the compound beam web after the assembling is the assembling of two corrugated webs, be equivalent to double corrugated web plate, can effectively improve stability and the supporting capacity of member, especially antitorque bearing capacity, the layout of web is cellular, can aspect the total bearing capacity of member, obtain optimal result, therefore with other like products, compare its mechanical property and significantly improve.
3, in the assembling honeycombed web combination beam that the present invention proposes, it is that the relation of having optimized between section mechanical property and product steel using amount makes it more be tending towards rationalization and scientific that section combines maximum characteristics, and then improve girder steel supporting capacity, reduce steel using amount, reduce construction costs, realize standardization large-scale production, significantly improve production efficiency.
