Gap.
The component of reinforcing bar is bigger, and the faying face between concrete is essentially all plane, by parallel with plane
Stress when, be easy at faying face separate.Basically, the anti-seismic performance of part steel reinforced concrete cannot fully play
Whether the key of the advantages of concrete steel is that continuity is excellent between steel and concrete.Two kinds of materials under external force
The reaction difference of various stress is big, and then two kinds of materials can resist external force with similar reaction to continuity by force, then can play compound
The advantage of material, and if two kinds of material reaction differences are big, will lead to can not be effective against external force, and component is easily damaged.
Specifically, existing steel reinforced concrete, stress indiscriminate can be conducted to concrete and reinforcing bar, i.e., stress passes
When leading the concrete near reinforcing bar and reinforcing bar, direction and size are not distinguished significantly.And concrete and the reaction of reinforcing bar stress
Difference is big, to just have different deformation in the interface of concrete and reinforcing bar.When earthquake, high frequency, high-intensitive vibration
Under, it is just easy to that SRC member is made to lose steel and the compound advantage of concrete, bearing capacity reduces rapidly, and then leads
It is irreversible impaired to cause building element, or even collapses.
Mud is first wrapped outside arc panel, by microwave sintering, forms the part reinforcing bar that hard pottery layer and steel fibre coexist
Strengthening part.Steel fibre extends to all directions, the contact surface very little of Single Fiber in concrete, and direction is different, can
Effective carrying transition each stress.Haydite in fiber exposure mud ball can make it closer with concrete binding.This dew
Fiber mud ball is abutted against on reinforcing bar surface by web, forms the nonmetallic and compound intermediate zone of metal in close.Made
It crosses area and reacts closer with the stress of reinforcing bar, avoid concrete and reinforcing bar from being detached from, so that it is compound with concrete that reinforcing bar is effectively ensured
Excellent mechanics formed, improve resist high frequency high-amplitude shock resistance.
In addition, the position that prestressed 20 one side of cordage is capable of guarantee section reinforcing bar strengthening part 10 is stablized, and energy
Enough to rectangular steel tube with pressure, casting concrete in rectangular steel tube is avoided to generate radial pressure to steel pipe.
Fiber concrete is preferred in concrete, is higher than in one layer of fiber consumption for closing on part reinforcing bar strengthening part 10
Outer concrete.Of course for convenient for construction, preferably in the outer tensioning web of part reinforcing bar strengthening part 10, stretch out fiber
Outside web, concrete is injected in 5-10mm, while to web two sides in the aperture of web.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All any modifications in spirit of that invention and principle, made are equal
Replacement, improvement etc., should all be included in the protection scope of the present invention.
