Abstract
The invention discloses a connecting joint of a steel pipe concrete column and a profile steel concrete beam. The intersection between a steel pipe in the steel pipe concrete column and a flange girth of the profile steel concrete beam is provided with a pair of large and small annular plates of different diameters; the horizontal and vertical positions of the two annular plates are staggered away from each other; the small annular plate is welded with a steel beam flange girth in the profile steel concrete beam; the large annular plate is welded with a longitudinal bar in the profile steel concrete beam; a steel pipe is arranged between the annular plates for welding the large and small annular plates into a whole; and the steel pipe of the steel pipe concrete column and the steel pipe for connecting the two annular plates are connected into a whole through a vertical rib. The connecting joint of the steel pipe concrete column and the profile steel concrete beam disclosed by the invention has the advantages that: 1, a large quantity of steel bar holes are not required to be formed on a steel pipe in a steel pipe concrete column; 2, damages to the section of a profile steel concrete column caused by steel pipe punching are avoided; and 3, convenience is brought to construction casting and compacting of concrete.
Description
Technical field
The present invention relates to a kind of building structure joint form, more particularly to the bean column node in reinforced concrete composite structure.
Background technology
At present, profile steel concrete column（Internal shaped steel is steel pipe）It is with steel reinforced concrete girder connection way：Steel pipe sets steel beam flange in one piece of ring flat-plate, section steel beam to be welded with ring flat-plate at section steel beam top flange in concrete filled steel tubular column, and shaped steel is worn in reinforcing bar part in section steel beam, and part bending bypasses steel pipe.This joint form unit in charge of construction must hold successfully to steel pipe in processing factory or scene and wear reinforcing bar hole, part beam steel important affair first carries out curved arc, job site can not often construct because reinforcing bar causes reinforcing bar to be collided too much, the damage to column section, and long construction period are caused to the steel pipe perforate in profile steel concrete column simultaneously.
The content of the invention
It is an object of the invention to provide a kind of new steel core concrete column and steel reinforced concrete beam connecting node, being mainly characterized by of the node can save the construction workload of scene and processing factory, shorten construction period, reduce labour cost, reduce cost.
What the present invention was achieved through the following technical solutions：A kind of connecting node of steel core concrete column and girder with rolled steel section en cased in concrete, it is characterised in that：The steel pipe large and small ring flat-plate different from edge of a wing intersection a pair of diameters of setting of girder with rolled steel section en cased in concrete in the post of steel core concrete column, two pieces of ring flat-plate levels, upper-lower positions stagger, the small ring flat-plate is welded with the steel beam flange in girder with rolled steel section en cased in concrete, muscle welding is indulged in the beam of the big ring flat-plate and girder with rolled steel section en cased in concrete, steel pipe is provided between the ring flat-plate welding of large and small ring flat-plate is linked as in entirety, the post of the steel core concrete column to connect to form entirety by vertical ribbed stiffener between steel pipe and the steel pipe for connecting two ring flat-plates.
Further, it is closely knit to ensure casting and compacting of concrete, it is provided with concrete casting hole on the small ring flat-plate.
The positive effect of the present invention is：1、Shorten the site operation duration.Former conventional node way needs to open substantial amounts of hole in round steel pipe, if perforate is constructed in processing factory, live reinforcing bar physical location is again usually variant with theory, can not often ensure consistent with live needs；If perforate is constructed at the scene, perforate difficulty is very big, because：1）, boring positioning is difficult on arcwall face, 2）, every reinforcing bar need out two through holes, holes requires alignment, and site operation is difficult.The present invention need not the perforate on steel pipe.The duration can be shortened.2nd, have a safety feature, it is to avoid the damage for the steel reinforced concrete column section that steel pipe perforate is caused, longitudinal reinforcement and the enforced loop plane of beam are welded, and construction is simple, and Welding Safety is reliable, it is ensured that the longitudinal reinforcement anchoring of beam.3rd, structure economics effect substantially, adds steel loop plate and peripheral steel pipe, reduces reinforcing bar length, total Master Cost does not have big increase.Reduce substantial amounts of steel pipe column perforate and wear reinforcing work.The construction workload of a large amount of scenes and processing factory is saved, shortens construction period, labour cost is reduced, so as to reduce cost.
