Abstract
The invention provides a hooped steel reinforced concrete beam-column joint of a core area U-shaped column, which relates to the field of constructional engineering. The hooped steel reinforced concrete beam-column joint of the core area U-shaped column comprises a column type steel flange plate, a column type steel web plate, a column horizontal stiffened steel plate, a column longitudinal bar, a column hoop, a column U-shaped hoop and a column concrete as well as a beam type steel flange plate, a beam type steel web plate, a beam longitudinal bar, a beam hoop and beam concrete; the beam-column joint core area is steel reinforced concrete structure building or structure of the U-shaped hoop. In the joint core area, the original closed hoop is replaced with the U-shaped hoop which is suitable for the structural forms at the beam-column joints of high-rise and super high-rise buildings. According to the invention, a column hoop through hole which is formed on the beam type steel web plate due to the need of enabling the column hoop to penetrate through the beam type steel web plate in the common steel reinforced concrete beam-column joint is avoided; one procedure is reduced in the member manufacturing process; the trouble of first penetrating through the reinforcing steel bar for making the hoop and then carrying out bending molding and segmental welding on the reinforcing steel bar during construction is prevented; and the beam-column joint can be manufactured in advance so that the construction period is shortened and the construction costs are saved.
Description
Technical field
The present invention relates to building engineering field, particularly relate to a kind of core space U-shaped tie muscle steel reinforced concrete beam column node.
Background technology
Steel reinforced concrete structure (or claim steel reinforced concrete structure) is made up of the longitudinal reinforcement of hot rolling or welding shaped steel, colligation and horizontal stirrup, the concrete of building jointly.In recent years; Because steel reinforced concrete structure has the advantage of steel work and concrete structure concurrently, bearing capacity is high, and anti-seismic performance is good; And can reduce characteristics such as construction costs, reduction of erection time, economical with materials, more and more be widely used among high-rise and the super highrise building.
In " reinforced concrete composite structure tecnical regulations " (JGJ 138-2001) of China, " steel reinforced concrete structure tecnical regulations " (YB 9082-2006); Bean column node is by column type steel frange plate 1, column type steel web 2, the post level steel plate 3 of putting more energy into; Post is indulged muscle 4, tie muscle 5, post concrete 6 and beam shaped steel frange plate 7, beam shaped steel web 8, the vertical muscle 9 of beam, beam stirrup 10, beam concrete 11 compositions; For the tie muscle 5 that can make joint cores passes beam shaped steel web 8 smoothly; On web 8, open through hole 12, let the tie muscle pass this hole, see accompanying drawing 1-2 so that stirrup is closed.
Node is the key position that connects beam and column.The internal force of beam and column is through the node transmission, and the safe and reliable of node is the prerequisite that guarantees structural safety work.Why steel reinforced concrete beam column node has higher shear resistant capacity; Be since steel plate under concrete parcel; The buckling problem that need not consider; The shearing at node place is born by steel plate 3 ribs of putting more energy into of shaped steel web 2 and level in core space concrete 6, stirrup 5 and the post respectively jointly, and therefore, the shear-carrying capacity of steel reinforced concrete structure bean column node is greater than the reinforced concrete structured beam post node and the pure steel structure bean column node shear-carrying capacity sum of same cross-sectional.
Regulation among " reinforced concrete composite structure tecnical regulations " (JGJ 138-2001), " steel reinforced concrete structure tecnical regulations " (YB 9082-2006) " when the reinforcing bar web part is provided with the reinforcing bar through hole, the damaged rate in cross section should not surpass the web area 20% ".At present in actual engineering; This form of architecture joints that mainly is in the code requirement to be recommended; In the manufacturing process of member,, brought great inconvenience for the making of steel member because perforate is less and the position needs accurately location; Position of opening often and the job site actual conditions be not inconsistent, cause the extension of construction speed and the problems such as increase of construction costs.
Summary of the invention
The object of the invention is to provide core space U-shaped tie muscle steel reinforced concrete beam column node; Solve traditional steel concrete bean column node in order to let the tie muscle pass and perforate on the section steel beam web; Give structure manufacture and the inconvenient problem that construction causes, be suitable for bean column node place structural form as high-rise and super highrise building.
The object of the invention is realized through following technical scheme:
Core space U-shaped tie muscle steel reinforced concrete beam column node; By column type steel frange plate, column type steel web, the post level steel plate of putting more energy into; Post is indulged muscle, tie muscle, post u tie muscle, post concrete and beam shaped steel frange plate, beam shaped steel web, the vertical muscle of beam, beam stirrup, beam concrete composition, and described bean column node core space is the steel reinforced concrete structure building or the structure of U type stirrup.Core space u tie muscle steel reinforced concrete beam column node is to adopt the u tie muscle to replace the joint form of original closed stirrups in joint cores.
Advantage of the present invention and effect are:
1. owing to adopted U type stirrup to replace the structural form of original closed stirrups, make in the structure manufacture process, need not definite tie muscle, avoided opening the operation of tie muscle through hole at beam shaped steel web in the position of running through of beam shaped steel web;
2. the reinforcing bar that will make stirrup when having saved construction earlier runs through the trouble of back bending forming or segmentation welding;
3. can make in advance, save the construction period, reduce construction cost.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
The present invention solves traditional steel concrete bean column node in order to let the tie muscle pass and perforate on the section steel beam web, the inconvenient problem of causing for structure manufacture and construction.Core space U-shaped tie muscle steel reinforced concrete beam column node is a kind of special shape of steel reinforced concrete structure bean column node, and joint cores adopts u tie muscle 13 to replace original closed stirrups 5, sees accompanying drawing 3-4.Simultaneously on beam shaped steel web, need not open tie muscle through hole 12, be suitable for bean column node place structural form as high-rise and super highrise building.
The present invention is shown in Fig. 3-4; By column type steel frange plate 1, column type steel web 2, the post level steel plate 3 of putting more energy into; Post is indulged muscle 4, tie muscle 5, post u tie muscle 13, post concrete 6 and beam shaped steel frange plate 7, beam shaped steel web 8, the vertical muscle 9 of beam, beam stirrup 10, beam concrete 11 compositions; During application, the sectional dimension of steel reinforced concrete beam column, shaped steel size, longitudinal reinforcement reinforcement ratio, stirrup reinforcement ratio, strength grade of concrete are confirmed according to engineering actual loading situation.
The requirement that connects design, processing and construction about concrete, steel member, vertical muscle, stirrup and node among the present invention all can by " Code for design of concrete structures " (GB50010-2010), " Code for design of steel structures " (GB50017-2003), " seismic design provision in building code " (GB50011-2010), " reinforced concrete composite structure tecnical regulations " (JGJ 138-2001), " steel reinforced concrete structure tecnical regulations " standards such as (YB 9082-2006), rules carry out.
