Abstract
The utility model discloses a side-sticking reinforcing column which comprises a conventional reinforced concrete frame column, a reinforced concrete column is added on one side of the column with a side sticking method, a high-strength steel reinforcement cage is equipped in the side-sticking column, and a plurality of horizontally arranged anchor ribs are arranged in the side-sticking column; the anchor ribs are arranged at intervals in the height direction of the column, one end of each anchor rib is anchored in the conventional column, and the other ends of the anchor rods and a steel reinforcement cage in a new reinforcing column are casted with concrete after integrally connected in fixed positions, a plurality of high-strength prestressed steel bars arranged in the height direction of the column at intervals are further arranged in side-sticking column, penetrate through preserved holes and are tensioned so as to improve the common working performance of the new and old structures. The side-sticking reinforcing column is simple in structure and convenient to construct, and the reinforcement effect that the structure shock resistance is improved greatly and fewer influences are produced on the use of conventional building space is realized.
Description
Technical field
The utility model relates to a kind of side and pastes reinforced column, belongs to building structure aseismatic reinforcing technique field.
Background technology
According to statistics, in the existing various buildings of China, the overwhelming majority is reinforced concrete structure, because the reason buildings such as earthquake disaster and artificial damage constantly produce various hidden danger, if do not taked anti-vibration reinforced measure, just likely produces security incident.For this reason, country need to drop into substantial contribution every year for seismic hardening and the maintenance of various buildings.In addition, although concrete intensity service rating is stipulated in standard, but because building is longer service life, member because the sunlight under extending service in the army is exposed to the sun, the impact of the environmental factor such as moist freeze thawing and acid and alkali corrosion, or because the impact of the factors such as design is improper, construction accident occurs that concrete strength is seriously on the low side, and then member, node equal strength is on the low side, formed Medium And Low Strength Steels tendon concrete frame structure, this will directly reduce the margin of safety of structure and have influence on the safety of building when earthquake occurs.On the other hand, along with the development of urban construction, underframe Multi-storey block need be arranged to the requirement in the functions such as little standard width of a room in an old-style house house because it can meet building to the indoor large space of bottom, top, and cost is more more economical and be widely adopted than multistory frame house.But this bottom flexible structure is all subject to heavy damage in all previous earthquake, even house all collapses.Therefore,, for improving the safety research exploitation simple structure of building under geological process, easy construction, on the less reinforcing technique of existing building impact, repairs significant to Seismic Strengthening.
Summary of the invention
The utility model has provided a kind of side and has pasted reinforced column, the object of invention is to be connected and fixed and newly to be established the position of reinforcing cage and improve together the cooperative ability of new and old structure with prestressed steel bar by anchor rib, while making earthquake, new and old structure formation one is carried out shared geological process, realizes and not only can significantly improve structural seismic capacity but also the normal use in existing building space is affected to less object.
the technical solution of the utility model is as follows:
Side is pasted a reinforced column, comprises the existing post of existing reinforced concrete, in a side side of described existing post, posts and reinforces new post, and the new post of described reinforcing comprises reinforcing cage and cast-in-situ concrete; Described side is pasted in reinforced column and is also comprised many horizontally disposed anchor ribs, and anchor rib arranges along the short transverse interval of post, and its one end is anchored in existing post, and its other end utilizes tied silk to link together with the reinforcing cage of reinforcing in new post; Described side is pasted in reinforced column and is also comprised the spaced prestressed steel bar of a plurality of short transverses along post, prestressed steel bar is outside equipped with built-in pipe, prestressed steel bar two ends are provided with nut, described prestressed steel bar level is through existing post and reinforce new post, and its two ends are anchored at respectively existing post and reinforce on a side of new post.
Compared with prior art, the present invention has the following advantages:
(1) this kind of Shockproof reinforcing method reasonable stress, power transmission are clear and definite, can determine the thickness in cross section according to load and distribution situation, thereby can process flexibly reinforcement and strengthening sectional dimension of members, reduce the impact on building space.
(2) high strength cast iron is applied to, in the anti-seismic reinforcement design of existing structure, can bring into play the advantage that high tensile reinforcement intensity is high, thereby compare the consumption that can reduce reinforcing bar with plain bars, has significant economic benefit.
(3) use of high-strength prestress rod iron, can obviously improve the cooperative ability between new and old structure.
(4) simple structure, difficulty of construction little, there is very high superiority of effectiveness, be adapted at extensively promoting in engineering.
accompanying drawing explanation
Accompanying drawing 2 is A-A sectional drawings in Fig. 1.
In figure:
The existing post of 1-steel concrete, 2-anchor rib, 3-newly establish frame column high tensile reinforcement cage, 4-penetrate the built-in pipe that prestressed steel bar is used, 5-high-strength prestress rod iron, 6-nut, 7-tied silk.
the specific embodiment
As shown in Figure 1, when existing frame column is reinforced, first roughening processing is carried out in the side of existing structure post (1), its degree of depth can be controlled in 10mm, also should the removing surface of processing is clean, to guarantee existing structure and newly to establish the performance of the concrete binding power between frame column.Then drill through anchor bar jack, boring row is two rows; Anchor rib (2) one end is put into jack and injected organic gel, and anchor rib other end extension value should newly be established cross-section of frame column width B at 1 times.The 3rd wants colligation newly establish frame column high tensile reinforcement cage (3) and by tied silk, it be connected with anchor rib (2), and concreting is interior and vibration compacting to template.In the process of vibrating, should avoid the anchor rib (2) in vibrating head collision reinforcing bar and reinforcing cage and penetrate the built-in pipe (4) that prestressed steel bar is used, preventing distortion and disturbance.After finally penetrating prestressed steel bar and carrying out stretch-draw, fastening nut is fixed, and completes the strengthening construction process to existing frame column.
The existing frame column of the present embodiment is identical with embodiment 1, and difference is that anchor rib (2) is only at existing frame column
(1) within the scope of 2 times of posts of upper and lower end parts (1) breadth of section b, two rows arrange, and newly to establish cross-section of frame column height L be 1.5 times of existing frame column (1) depth of section.All the other structures, with embodiment 1, are not described in detail in this.
The existing frame column of the present embodiment is identical with embodiment 1, and difference is that anchor rib (2) is in existing frame column (1)
The single layout of longitudinal axis direction, and newly to establish cross-section of frame column height L be 0.75 times of existing frame column (1) depth of section.
All the other structures, with embodiment 1, are not described in detail in this.
Be more than several exemplary embodiments of the present utility model, enforcement of the present utility model is not limited to this.
