Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings reinforcing steel bar assembly 10 according to the embodiment of the present invention is described.As shown in Fig. 1-Fig. 7, comprise confinement tube 101, reinforcing bar 102 and packed layer 103 according to the reinforcing steel bar assembly 10 of the embodiment of the present invention.
Reinforcing bar 102 has first end 1021 and the second end 1022, and reinforcing bar 102 is located in confinement tube 101, and at least one in the first end 1021 of reinforcing bar 102 and the second end 1022 stretches out confinement tube 101.Packed layer 103 is filled in the space between confinement tube 101 and reinforcing bar 102.In other words, packed layer 103 is sleeved on reinforcing bar 102, and confinement tube 101 is sleeved on packed layer 103.
Reinforcing steel bar assembly 10 according to the embodiment of the present invention can be used alone, also can to combinationally use together with other reinforcement welding.Specifically, the part of stretching out confinement tube 101 of reinforcing bar 102 can together with other reinforcement welding.
Reinforcing bar there will be elastic buckling or surrender post-buckling when pressurized, cause the forfeiture of steel reinforcement bearing capacity and energy dissipation capacity.In known reinforced concrete structure; longitudinal reinforcement is generally arranged along structural perimeter, and when structure compression damage, topping peels off; the drum that inner concrete generation lateral expansion causes compressive reinforcement more easily to occur to member exterior is bent, causes the forfeiture of the supporting capacity of component.
After carrying out parcel constraint by utilizing confinement tube 101 and packed layer 103 pairs of reinforcing bars 102, as long as external structure has enough hoop rigidities, the lateral deformation of reinforcing bar 102 can be retrained effectively, thus makes the part of reinforcing bar 102 in confinement tube 101 flexing not occur.
According to the reinforcing steel bar assembly 10 of the embodiment of the present invention by utilizing confinement tube 101 and the packed layer 103 be filled between confinement tube 101 and reinforcing bar 102 retrains the part of reinforcing bar 102, thus can guarantee that reinforcing bar 102 flexing does not occur in restriction range, namely there is not flexing in the part being positioned at confinement tube 101 of reinforcing bar 102, greatly can improve anti-seismic performance and the bearing capacity of the building structure using reinforcing steel bar assembly 10 thus.
And, according to the reinforcing steel bar assembly 10 of the embodiment of the present invention, there is simple structure, apply conveniently, be easy to prefabrication, reduce the advantages such as difficulty of construction, thus make reinforcing steel bar assembly 10 become the building unit of low-cost and high-performance, can produce in batches, be applicable in current all kinds of building structure, the performance of building structure can be promoted, there is higher technical economic benefit.
In the bottom column that may be used for general structure according to the reinforcing steel bar assembly 10 of the embodiment of the present invention and super high rise structure.When guarantee conventional concrete construction method, construction measure change little, reinforcing steel bar assembly 10 can be conveniently used in concrete structure, replace the reinforcing bar that in concrete structure, axial pressure is larger, thus improve bearing capacity and the anti-seismic performance of concrete structure.
Therefore, according to the reinforcing steel bar assembly 10 of the embodiment of the present invention, there is not easily flexing, the advantage such as bearing capacity is large, anti-seismic performance is good.
