Description
Technical field
The present invention relates to construction engineering technical field, particularly relate to the reinforced concrete post of the sub-spiral stirrup of a kind of additional variable diameters.
Background technology
At present, China is in the earthquake high-incidence season, from the experience of Wenchuan earthquake and Lushan earthquake, under the seismic force effects that earthquake magnitude is higher, pillar damage comparison in Multistory reinforced conceete frame Structure is serious, and particularly at the two ends of pillar, concrete is shattered, multiple Reinforcement is that lantern-shaped bulges, and collapses in the badly damaged even local of frame construction.Especially on the top of frame column, do not occur the failure mode of " strong column and weak beam " required by seismic design, beam-ends is also substantially intact often, the multiple Reinforcement in frame column top cripling, pressure zone concrete serious damage.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the reinforced concrete post of the sub-spiral stirrup of a kind of additional variable diameters, by multiple sub-spiral stirrup additional in reinforced concrete post, not only effectively can prolong the flexing of resistance frame column top Reinforcement, simultaneously, the existence of multiple sub-spiral stirrup, concrete ductility and concrete intensity can be improved greatly again, thus increase the anti-seismic performance of frame construction entirety, there is great economy and social value.
For solving the problems of the technologies described above, the invention provides the reinforced concrete post of the sub-spiral stirrup of a kind of additional variable diameters, comprise: pillar body, multiple Reinforcement and multiple sub-spiral stirrup, described multiple Reinforcement is vertically fixed in multiple post angles of described pillar body, described multiple sub-spiral stirrup is fixed on the top of described pillar body, and bond described multiple Reinforcement respectively, the diameter range of described multiple sub-spiral stirrup is 50-100mm, increases successively from top to bottom.
In a preferred embodiment of the present invention, the shape of described multiple Reinforcement is cylindrical, and the diameter range of lateral cross section is 12-32mm, and cold stretch rate is less than 1%.
In a preferred embodiment of the present invention, the quantity of described multiple sub-spiral stirrup is greater than or equal to 4.
In a preferred embodiment of the present invention, the quantity of described multiple Reinforcement is greater than or equal to the quantity of described multiple sub-spiral stirrup.
The invention has the beneficial effects as follows: the reinforced concrete post that the present invention adds the sub-spiral stirrup of variable diameters have effectively prolong hinder multiple Reinforcement flexing, greatly improve concrete ductility and intensity, antidetonation shock attenuation, the advantage such as sturdy and durable, safe and reliable, economical and practical.

In accompanying drawing, the mark of each parts is as follows: 1, pillar body, and 2, multiple Reinforcement, 3, multiple sub-spiral stirrup.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A reinforced concrete post for the sub-spiral stirrup of additional variable diameters, comprising: pillar body 1, multiple Reinforcement 2 and multiple sub-spiral stirrup 3.
Described multiple Reinforcement 2 is vertically fixed in multiple post angles of described pillar body 1, the reinforcing bar meeting bearing capacity is set in force part by mechanical calculation, be used for meeting the requirement of structural strength and rigidity, described multiple sub-spiral stirrup 3 is fixed on the top of described pillar body 1, and bond described multiple Reinforcement 2 respectively, effectively prolong the flexing of the multiple Reinforcement 2 in resistance frame column top, greatly increase again concrete ductility and concrete intensity simultaneously, by addition of multiple sub-spiral stirrup 3, thus add the anti-seismic performance of frame construction entirety, there is great economy and social value, the diameter range of described multiple sub-spiral stirrup 3 is 50-100mm, increase successively from top to bottom, screw diameter is bottom the half of the width of the lateral cross section of pillar body 1, multiple so sub-spiral stirrup 3 can wrap up more concrete, thus further increase concrete intensity and ductility.
Preferably, the shape of described multiple Reinforcement 2 is cylindrical, and the diameter range of lateral cross section is 12-32mm, and in order to reduce buckling, prevent the too early lateral deflection of vertical muscle, cold stretch rate is less than 1%.
Preferably, the quantity of described multiple sub-spiral stirrup 3 is greater than or equal to 4, the shape of the pillar body 1 considered here is rectangle, then the position of multiple sub-spiral stirrup 3 is evenly fixed on the corner of pillar body 1, for circular posts, then the quantity of multiple sub-spiral stirrup 3 is greater than 8, also for being uniformly distributed.
Preferably, the quantity of described multiple Reinforcement 2 is greater than or equal to the quantity of described multiple sub-spiral stirrup 3, multiple Reinforcements 2 for the bight being positioned at pillar body 1 can adopt and the mode of muscle, and that is the Reinforcement that bonds of every sub-spiral stirrup sometimes and more than one.
The beneficial effect of the reinforced concrete post of the sub-spiral stirrup of a kind of additional variable diameters of the present invention is:
One, by multiple sub-spiral stirrup additional in reinforced concrete post, multiple sub-spiral stirrup is utilized to bond multiple Reinforcements in post, not only effectively can prolong the flexing of the multiple Reinforcement in resistance frame column top, concrete ductility and concrete intensity can be improve greatly again simultaneously, thus add the anti-seismic performance of frame construction entirety, there is great economy and social value;
Two, be limited in 12-32mm by the diameter range of the lateral cross section by multiple Reinforcement, decrease buckling, prevent the too early lateral deflection of vertical muscle, improve quality and the solidness of multiple Reinforcement;
Three, by being uniformly distributed multiple sub-spiral stirrup, adding stressed degree and the intensity of general frame, further increasing the shock resistance of framework.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
