Description

Core space adopts the Steel Reinforced Concrete Beam-column Joints of steel plate with holes
Technical field
The present invention relates to a kind of building structure bean column node, particularly relate to a kind of core space and adopt steel plate with holes to replace the Steel Reinforced Concrete Beam-column Joints of column tie-bar.
Background technology
Steel reinforced concrete structure (or claim steel reinforced concrete structure) is made up of jointly the longitudinal reinforcement of hot rolling or welding shaped steel, colligation and horizontal hoop, the concrete of building.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 the features such as construction costs, reduction of erection time, saving material can be reduced, be more and more widely used among high-rise and super highrise building.
In China, see accompanying drawing 1-2, " reinforced concrete composite structure tecnical regulations " (JGJ138-2001), in " steel reinforced concrete structure tecnical regulations " (YB9082-2006), bean column node is by post shaped steel flange plate 1, post shape steel web 2, post sash steel plate 3, muscle 4 indulged by post, column tie-bar 5, post concrete 6 and beam shaped steel flange plate 7, beam shape steel web 8, beam indulges muscle 9, beam stirrup 10, beam concrete 11 forms, beam shape steel web 8 is passed through in order to the column tie-bar 5 of joint cores can be made, web 8 is opened through hole 12, allow column tie-bar pass this hole close to make stirrup.
Node is the key position connecting beam and column.The internal force of beam and column is transmitted by node, and the safe and reliable of node is the prerequisite ensureing structural safety work.Why Steel Reinforced Concrete Beam-column Joints has higher shear resistant capacity, because steel plate is under concrete parcel, the buckling problem that need not consider, the shearing of Nodes is respectively by shape steel web 2 in core space concrete 6, stirrup 5 and post and sash steel plate 3 rib shared, therefore, the shear-carrying capacity of steel reinforced concrete structure bean column node is greater than reinforced concrete structured beam Column border node and the pure steel structure bean column node shear-carrying capacity sum of same cross-sectional.
Regulation " when reinforcing bar web part arranges reinforcing bar through hole, cross section defect rate should not exceed 20% of web area " in " reinforced concrete composite structure tecnical regulations " (JGJ138-2001), " steel reinforced concrete structure tecnical regulations " (YB9082-2006).At present in Practical Project, this form of architecture joints of mainly recommending in code requirement, in the manufacturing process of component, because the less and position of perforate needs accurately location, great inconvenience is brought to the making of steel beam column, position of opening often and job site actual conditions be not inconsistent, cause the problem such as the extension of construction speed and the increase of construction costs.
Summary of the invention
A kind of core space is the object of the present invention is to provide to adopt the Steel Reinforced Concrete Beam-column Joints of steel plate with holes, core space adopts steel plate with holes to be welded by groove weld with section steel beam web, joint form does not need out column tie-bar through hole on beam shape steel web, be suitable for the bean column node place structural form as high-rise and super highrise building, when eliminating construction, first the reinforcing bar making stirrup run through the trouble of rear bending forming or segmentation welding.
The object of the invention is to be achieved through the following technical solutions:
Core space adopts the Steel Reinforced Concrete Beam-column Joints of steel plate with holes, indulge muscle, column tie-bar, steel plate with holes, post concrete and beam shaped steel flange plate by post shaped steel flange plate, post shape steel web, post sash steel plate, post, beam shape steel web, beam indulge muscle, beam stirrup, beam concrete form, the core space of described node adopts steel plate with holes, and steel plate with holes and section steel beam web are by groove weld solder bond.
Described core space adopts the Steel Reinforced Concrete Beam-column Joints of steel plate with holes, and described steel plate is welded on short steel beam web plate in advance.
Advantage of the present invention and effect are:
1. when present invention eliminates construction, first the reinforcing bar making stirrup is run through the trouble of rear bending forming or segmentation welding.
2. steel plate of the present invention can be welded on short steel beam web plate in advance, saves the construction period, reduces construction cost.
3. the present invention is applicable to building, the structure that beam column node core area adopts the steel reinforced concrete structure of steel plate with holes replacement column tie-bar.

Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is described in detail.
The present invention is directed to the perforate on section steel beam web in order to allow column tie-bar pass of traditional Steel Reinforced Concrete Beam-column Joints, to structure manufacture and the inconvenience caused of constructing, core space adopts steel plate with holes to replace the Steel Reinforced Concrete Beam-column Joints of column tie-bar to be a kind of special shape of steel reinforced concrete structure bean column node, joint cores adopts steel plate 13 with holes to replace original closed stirrups 5, steel plate 13 with holes is welded by groove weld 14 with section steel beam web 8, sees accompanying drawing 3-6.This joint form does not need out column tie-bar through hole 12 on beam shape steel web, is suitable for the bean column node place structural form as high-rise and super highrise building.Replace column tie-bar 5 at core space steel plate 13 with holes, steel plate 13 and section steel beam web 8 are welded together by groove weld 14.
As seen in figures 3-6, the present invention indulges muscle 4, column tie-bar 5, steel plate with holes 13, post concrete 6 and beam shaped steel flange plate 7 by post shaped steel flange plate 1, post shape steel web 2, post sash steel plate 3, post, beam shape steel web 8, beam indulge muscle 9, beam stirrup 10, beam concrete 11 form, during application, the sectional dimension of steel reinforced concrete beam column, shaped steel size, steel plate thickness with holes, longitudinal steel ratio values, stirrup reinforcement ratio, strength grade of concrete are determined according to engineering actual loading situation.
The present invention is that a kind of special shape of steel reinforced concrete structure bean column node is applied to building engineering field.Joint cores adopts steel plate with holes to replace original closed stirrups, is suitable for the bean column node place structural form as high-rise and super highrise building.This invention avoids in common Steel Reinforced Concrete Beam-column Joints, first the reinforcing bar making stirrup is run through the trouble of rear bending forming and segmentation welding during construction; Steel plate with holes can be welded on short steel beam web plate in advance, saves the construction period, saves construction costs.
About concrete in the present invention, steel beam column, vertical muscle, stirrup and node connect design, the requirement of processing and construction 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 " (JGJ138-2001), specifications such as " steel reinforced concrete structure tecnical regulations " (YB9082-2006), code performs.
