Description
Technical field
The present invention relates to the armored concrete structural element of field of civil engineering.
Background technology
At present, armored concrete beam as no antidetonation requirement, its cross section depth of compression zone generally is not more than balanced depth of compression zone, the depth of compression zone that the armored concrete beam of shockproof requirements is arranged is 0.25～0.35 effective depth of section, that is to say that the sectional dimension that is subjected to kinking structure member is often by allowing that relative height of compression zone decides.And when since function of use require beam section size-constrained the time, ordinary concrete is subjected to the nip reinforcing bar of kinking structure member usually to join very intensively, make concrete build very inconvenient.
Summary of the invention
The objective of the invention is for reducing by the flexural member depth of section of allowing depth of compression zone control; Solve simultaneously because the requirement of function of use when being subjected to kinking structure member section size-constrained, ordinary concrete is subjected to the nip reinforcing bar configuration of kinking structure member intensive and make the concrete problem such as very inconvenience of building.The armored concrete that the invention provides a kind of tension and compression district and be special strong concrete is subjected to kinking structure member.The present invention is made up of the high-strength or super high strength concrete 1 of cross section pressure zone, ordinary concrete 2, longitudinal reinforcement 3 and the stirrup 5 of tensile region, cross section; High-strength or the super high strength concrete 1 of cross section pressure zone and the ordinary concrete of tensile region, cross section 2 sclerosis backs form whole, and longitudinal reinforcement 3 and stirrup 5 are built in the ordinary concrete 2 of the high-strength or super high strength concrete 1 of cross section pressure zone and tensile region, cross section.Also having a kind of tension and compression district is the slab 10 of special strong concrete, and it is made up of the high-strength or super high strength concrete 1 of cross section pressure zone, ordinary concrete 2, longitudinal reinforcement 3 and the transverse reinforcement 4 of tensile region, cross section; High-strength or super high strength concrete 1 both sides and the downside of cross section pressure zone are ordinary concrete 2, and longitudinal reinforcement 3 and transverse reinforcement 4 are built in the ordinary concrete 2 of the high-strength or super high strength concrete 1 of cross section pressure zone and tensile region, cross section.Adopt the present invention can obviously reduce, possess and pure high-strength or stress performance that the super high strength concrete beam is close, can obviously improve the function of use of building or structure, remarkable in economical benefits by the sectional dimension of allowing the relative height of compression zone decision; When being subjected to kinking structure member section size-constrained, adopt the present invention can obviously reduce the nip amount of reinforcement, not only simplify construction, and guaranteed workmanship.
