Abstract
The invention relates to building structure beam column nodes, in particular to a steel reinforced concrete beam column node with a core area using a porous steel plate. The steel reinforced concrete beam column node comprises a column steel flange plate, a column steel web, a column horizontal stiffening steel plate, a column longitudinal rib, a column hooping, the porous steel plate, column concrete, a beam steel flange plate, a beam steel web, a beam longitudinal rib, a beam hooping and beam concrete. The core area of the node uses the porous steel plate 13 which is welded with the beam steel web 8 through a groove-welded joint 14. The steel plate is welded on the short beam steel web in advance. The steel reinforced concrete beam column node is suitable for beam column node of high and ultrahigh buildings. The trouble that bending forming is performed to the rebars, after penetration, for making hoopings and welding needs to be performed in sequence is saved. The porous steel plate can be welded on the short beam steel web in advance, construction period is shortened, and construction cost is saved.
Description
Technical field
The present invention relates to a kind of building structure beam column node, particularly relate to a kind of core space and adopt steel plate with holes to replace the steel reinforced concrete beam column node of tie muscle.
Background technology
Steel reinforced concrete structure (or claim steel reinforced concrete structure) is made of jointly the longitudinal reinforcement of hot rolling or welding shaped steel, colligation and horizontal stirrup, the concrete of building.In recent years, because steel reinforced concrete structure has the advantage of steel work and concrete structure concurrently, the bearing capacity height, 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 China, see accompanying drawing 1-2, " reinforced concrete composite structure tecnical regulations " (JGJ 138-2001), among " 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, beam is indulged muscle 9, beam stirrup 10, beam concrete 11 is formed, for the tie muscle 5 that can make joint cores passes beam shaped steel web 8 smoothly, open through hole 12 at web 8, allow the tie muscle pass this hole so that the stirrup closure.
Node is the key position that connects beam and column.The internal force of beam and column is by 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 jointly 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, therefore, the shear-carrying capacity of steel reinforced concrete structure bean column node is greater than 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 arranges the reinforcing bar through hole, the damaged rate in cross section should not surpass the web area 20% ".At present in actual engineering, it mainly is this form of architecture joints of recommending in the code requirement, in the manufacturing process of member, because perforate is less and the position needs accurately location, brought great inconvenience for the making of steel member, 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 present invention is to provide a kind of core space to adopt the steel reinforced concrete beam column node of steel plate with holes, core space adopts steel plate with holes and section steel beam web to weld by groove weld, joint form need not opened tie muscle through hole on beam shaped steel web, be suitable for the bean column node place structural form as high-rise and super highrise building, the reinforcing bar that will make stirrup when having saved construction earlier runs through the trouble of back bending forming or segmentation welding.
The objective of the invention is to be achieved through the following technical solutions:
Core space adopts the steel reinforced concrete beam column node of steel plate with holes, formed by the put more energy into vertical muscle of steel plate, post, tie muscle, steel plate with holes, post concrete and beam shaped steel frange plate, beam shaped steel web, the vertical muscle of beam, beam stirrup, beam concrete of column type steel frange plate, column type steel web, post level, the core space of described node adopts steel plate with holes, and steel plate with holes and section steel beam web are by the groove weld solder bond.
Described core space adopts the steel reinforced concrete beam column node of steel plate with holes, and described steel plate is welded on the short section steel beam web in advance.
Advantage of the present invention and effect are:
1. the reinforcing bar that will make stirrup when the present invention has saved construction earlier runs through the trouble of back bending forming or segmentation welding.
2. steel plate of the present invention can be welded on the short section steel beam web in advance, saves the construction period, reduces construction cost.
3. the present invention is applicable to that the bean column node core space adopts steel plate with holes to replace building, the structure of the steel reinforced concrete structure of tie muscle.
