Description
Technical field
The present invention relates to the reinforcing bars of the realm of building construction, and in particular to a kind of Ribbed Bar that cross rib is staggered.
Background technology
With the raising of steel strength, the cementation between reinforcing bar and concrete requires higher, existing reinforcing bar appearance
The setting pattern of face rib cannot be satisfied high tensile reinforcement and bonding for concrete requires, it is therefore desirable to existing reinforcing bar outer surface rib
Pattern be improved and innovate, to promote the mechanical snap power between reinforcing bar and concrete.
Currently, the cross rib of domestic construction Ribbed Bar mainly has Rib Reinforced, humanoid rib and screw thread rib etc. several, it is main
It is to improve the mechanical snap power of reinforcing bar and concrete, the anchoring ability of reinforcing steel bar.In order to improve the mechanical strength of cross rib,
Rebar surface is also symmetrical arranged two longitudinal ribs along reinforcing bar length direction, and cross rib is then symmetrically distributed between this two longitudinal ribs.Tool
When thering is the reinforced concrete member of the reinforcing bar of above structure to be in status under loading, the weak point set of rebar surface and concrete binding
In in longitudinal rib, the destruction of reinforced concrete member also mostly takes place from longitudinal rib；And cause reinforced concrete member damaged
Cracks in reinforced concrete width it is related with the cohesive force between concrete and reinforcing bar, cohesive force is bigger, distress in concrete
Width is smaller.Therefore, common Ribbed Bar needs many construction measures that could realize the control to cracks in reinforced concrete.And
And since cross rib is unevenly distributed in rebar surface, the cohesive force between the reinforcing bar and concrete of above structure has distribution not
Uniform disadvantage.
