Description
Technical field
The present invention relates to a kind of thin-walled C-shaped steel connecting structure.
Background technology
Thin-walled C-shaped steel is an architectural shape commonly used at present, and C shaped steel characteristics are steel plate wall thickness, and this makes material economy, can effectively bring into play the effect of steel simultaneously.But because steel plate is thinner, welding or the bolt connection adopted for the structure link technique that has C shaped steel now all are restricted, so that C shaped steel can not be widely used.
External normally used its thickness of C shaped steel is in 1mm, and the C shaped steel thickness of domestic use because C shaped steel wall is thin, therefore, just should not adopt following connected mode commonly used on C shaped steel syndeton in 2.5mm:
If welding---adopt welding,, cause the welding procedure difficulty very big because of C shaped steel wall is thin; Cost is higher, easy burn-through during welding, thus have influence on the intensity of structure; Be difficult to ensure the validity of syndeton, and the dismounting of welded construction when finishing using is quite difficult.
Be spirally connected---it is main being spirally connected with extruding and shearing resistance, and C shaped steel wall is thin, and its extruding and shear resistance are lower, cause C shaped steel to deform easily, influence the intensity of syndeton, and spiro connection structure is comparatively complicated.
More than two kinds of connected modes all have " damaging " structure and connect, big to C shaped steel damaged condition, influence application life of C shaped steel, recycling rate of waterused is lower.
In sum, existing thin-walled C-shaped steel connecting structure exists complex structure, cost is higher, the assembly and disassembly technology difficulty is big technological deficiency.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, provide a kind of simple in structure, cost is low, assembling is convenient, the thin-walled C-shaped steel connecting structure of long service life.
The technical scheme that the present invention adopted is: the present invention includes main cross bar, inferior cross bar, lapping fastener, support column, column bracket spare, said main cross bar and time cross bar are the thin-walled C-shaped steel standard component, and said lapping fastener is provided with U type groove and said main cross bar is suitable; The two side of said U type groove is provided with two banking stops; Be provided with bearing between two said banking stops of the same side, be provided with draw-in groove I between the sidewall of said banking stop and said U type groove, the both ends of said cross bar are combined with the eye-splice part; Said eye-splice part comprises insert-connecting plate; Said insert-connecting plate both upper ends thereof is provided with spacing block set, said spacing block set and said draw-in groove I clamping mutually, the bottom at said cross bar two ends and said bearing contact matching; The bottom of said column bracket spare is fixedly connected with said support column; Said column bracket spare is in the form of slot, and said main cross bar is enclosed within on the said column bracket spare in the form of slot, and said column bracket spare both sides cell wall is provided with breach and cooperates with the banking stop of said lapping fastener.
Further, the both sides cell wall of said column bracket spare is provided with to projecting inward protuberance, the cooperation that contacts with the two sides of said main cross bar of said protuberance.
The abutting end of said eye-splice part and said cross bar is a C shaped steel, the C shaped steel opening of said eye-splice part towards with the C shaped steel opening of said cross bar towards on the contrary.
Be provided with draw-in groove II between the sidewall of said bearing and said U type groove, the insert-connecting plate bottom of said eye-splice part and said draw-in groove II clamping mutually.
Said support column and said column bracket spare junction are provided with reinforcement.
Said column bracket spare is provided with hold-down screw with the contact matching place, bottom of said main cross bar; The two side of said U type groove cooperates the contact site to be provided with hold-down screw with said main cross bar; The matching part of said eye-splice part and said cross bar is provided with hold-down screw.
The invention has the beneficial effects as follows: thin-walled C-shaped steel connecting structure according to the invention adopts main cross bar, inferior cross bar, lapping fastener to overlap, and makes the connection between the member reach the connection of " non-damage " property structure, and is simple for assembly process, quick; Can install at the scene, after finishing using, can on-the-spot fast quick-detach; C shaped steel is not caused damage, therefore, can improve the application life of syndeton greatly; And but the section bar recycling rate of waterused is high, and the overall structure cost is low, in the syndeton of the present invention; Said time the suffered active force of cross bar is transferred on the said main cross bar through said lapping fastener; Active force is acted on the said support column through said column bracket spare by said main cross bar, the conduction of active force is rationally effective again, thereby overall structure of the present invention structure safety, reliable.
The present invention can be widely used in detachable lightweight steel construction or permanent steel work; In building floor support and scaffold construction, significant practical value is arranged simultaneously, can support than ordinary steel and save more steel, install simply.Application prospect is extensive in the building scaffold field in the present invention, and thin-walled C-shaped steel connecting structure provided by the invention is compared with existing connection system for guide rail, can practice thrift 40% aspect the steel saving, thereby can wide popularization and application.
