Abstract
The utility model discloses a shock-resistant reinforcing device for reinforced concrete beam-column joints. The shock-resistant reinforcing device comprises the a reinforced concrete beam and a steel band hoop, wherein a reinforced concrete column vertically intersects with the reinforced concrete beam; one end of the reinforced concrete beam which is tightly jointed with the side face of the reinforced concrete column is provided with grooves which are formed at equal intervals; and the steel band hoop passes through the grooves and is enclosed around the reinforced concrete column. The shock-resistant reinforcing device has the advantages of simple structure, low cost, high performance, wide popularization and application prospect and good engineering application value.
Description
Technical field
The utility model belongs to field of civil engineering, relates to building structure, relates in particular to a kind of reinforced concrete beam column node anti-seismic strengthening device.
Background technology
The bean column node of reinforced concrete frame structure is the frame construction critical component in building construction and the industrial construction, the joint cores anti-seismic performance is the key factor that influences the reinforced concrete structure anti-seismic performance, along with seismic design requires to improve, the often difficult satisfied existing code requirement of existing reinforced concrete beam column node anti-seismic performance, how adopting reasonable reinforcement means effectively to improve existing reinforced concrete beam column node anti-seismic performance is reinforced concrete structure strengthening reconstruction important research direction, and do not have very effective ways and technology at present, become the difficult point that reinforced concrete structure is reinforced.Along with earthquake disaster situation a few days ago is on the rise, reinforced concrete beam column node seismic hardening new technology and new method R﹠D work are increasingly important and urgent.
Because construction is inconvenient, increase adds stirrup or hoop plate around being difficult in the reinforced concrete beam column node core space, common method is to carry out the seismic hardening of reinforced concrete beam column node core space at reinforced concrete beam column node core space parcel FRP cloth at present, but because this type of shearing resistance reinforcement means only is that the reinforced concrete beam column node concrete is produced the passive bound effect, and this passive bound effect is not very remarkable, reinforce back FRP cloth and concrete simultaneously glassbreak takes place gradually easily, so this reinforcement means has big limitation.At present, both at home and abroad, reinforcing does not have the full maturity technology about the reinforced concrete beam column node core space, and the bean column node seismic hardening becomes the difficult problem of reinforced concrete frame structure seismic hardening.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of reinforced concrete beam column node anti-seismic strengthening device, and this simple in structure, with low cost, function admirable have wide popularization and application prospect and good engineering using value.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of reinforced concrete beam column node anti-seismic strengthening device, comprise reinforced concrete beam 2, reinforced concrete post 1 intersects vertically with reinforced concrete beam 2, an end of being close to reinforced concrete post 1 side on reinforced concrete beam 2 has the groove of equidistant distribution, also comprise steel band hoop 3, steel band hoop 3 passes described groove around reinforced concrete post 1 closure.
Fill Embedding Material in the described groove.
In the mortar brushing of the outside of described steel band hoop 3.
The utility model compared with prior art has the following advantages:
1) constructing operation is simple.
2) draw materials conveniently.
3) steel band intensity height effectively improves reinforced concrete beam column node core space shear strength and anti-seismic performance.
4) good endurance.
5) cheap, applied range.

Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a lateral view of the present utility model.
Fig. 4 is reinforced concrete post and three vertical views that reinforced concrete beam intersects.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in Figure 1 to Figure 3, the utility model is a kind of reinforced concrete beam column node anti-seismic strengthening device, comprise reinforced concrete beam 2, reinforced concrete post 1 intersects vertically with reinforced concrete beam 2, an end of being close to reinforced concrete post 1 side on reinforced concrete beam 2 has the groove of equidistant distribution, also comprise steel band hoop 3, steel band hoop 3 passes described groove around reinforced concrete post 1 closure.Fill Embedding Material in the described groove.
The utility model is applicable to the various situations that reinforced concrete post and reinforced concrete beam intersect, and wherein the crossing situation of reinforced concrete post and three reinforced concrete beams as shown in Figure 4.
In the utility model, steel band hoop 3 adopts pneumatic baling press that steel band is sealed packing, therefore have very big precompression, can adjust the given atmospheric pressure value of air compressor machine control steel band packing elasticity according to actual conditions during construction, adjust the steel band hoop to reinforced concrete beam column node core space degree of restraint to reach designing requirement.
In the mortar brushing of the outside of described steel band hoop 3, both can effectively protect steel band and the employed packing button 4 of packing, prevent to get rusty, whole node has been increased together reinforced again, and good looking appearance.
The steel band product variety that the utility model adopts is abundant, complete in specifications, purchase is convenient, need not special processing and customization, ultimate strength all can be up to more than the 900MPa for existing all kinds steel band (steel band that turns blue, stainless steel band, galvanized steel strip etc.), can provide very high constraint tightening force to the reinforced concrete beam column node core space by adjusting pneumatic baling press atmospheric pressure value, effectively improve reinforced concrete beam column node core space shear strength and anti-seismic performance.
The utility model can adopt materials such as stainless steel band, carbon fiber tape, galvanized steel strip to reinforce, has good durability, be very suitable for having all kinds of buildings and the industrial premises of corrosive environment, be applicable to square column, rectangular column, the seismic hardening of the various cross sectional shape reinforced concrete beam column node of circular columns core space simultaneously, range of application is extremely extensive.
