Description

Adopt the steel reinforced concrete beam column node of steel plate with holes up and down at core space

Technical field

The utility model relates to a kind of building structure beam column node, particularly relates to a kind of steel reinforced concrete beam column node that adopts steel plate with holes at core space up and down.

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.

" reinforced concrete composite structure tecnical regulations " (JGJ 138-2001) in China, 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 is seen accompanying drawing 1-2.

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 purpose of this utility model is to provide a kind of steel reinforced concrete beam column node that adopts steel plate with holes at core space up and down.This node solves traditional steel concrete bean column node in order to allow the tie muscle pass and perforate on the section steel beam web, the inconvenient problem of causing for structure manufacture and construction.

The purpose of this utility model is achieved through the following technical solutions:

Adopt the steel reinforced concrete beam column node of steel plate with holes up and down at core space, by column type steel frange plate, column type steel web, post level put more energy into the vertical muscle of steel plate, post, tie muscle, go up steel plate with holes, steel plate with holes, post concrete and the section steel beam edge of a wing, beam shaped steel web, the vertical muscle of beam, beam stirrup, beam concrete are formed down, this node is the joint form of arranging steel plate with holes in joint cores up and down; Namely arrange two steel plates with holes up and down up and down respectively in joint cores, go up steel plate with holes, following steel plate with holes and the section steel beam edge of a wing and weld together by last groove weld, following groove weld respectively,

Describedly adopt the steel reinforced concrete beam column node of steel plate with holes up and down at core space, described steel plate with holes welds together by edge weld between each side.

Advantage of the present utility model and effect are:

1. the reinforcing bar that will make stirrup when the utility model has saved construction earlier runs through the trouble of back bending forming or segmentation welding;

2. steel plate with holes can be welded on the last bottom flange of shaped steel short beam in advance about the utility model, saves the construction period, reduces construction cost.

3. the utility model is widely used, and all bean column node core spaces adopt steel plate with holes to replace building, the structure of the steel reinforced concrete structure of tie muscle all can up and down.
