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 is adopted in welding, because of C shaped steel wall is thin, cause the welding procedure difficulty very big, 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 suitable difficulty of the dismounting of welded construction when finishing using.
Be spirally connected---be spirally connected based on extruding and shearing resistance, and C shaped steel wall is thin, 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.
