Background technology
Development along with Urbanization in China; Large Space at Lower Part or super highrise building are more and more, in this type of building, because pillar bears very big axial pressure; Architectural design requires the pillar size can not be excessive again, thereby often adopts steel core concrete column or profile steel concrete column in the engineering.Characteristics such as steel core concrete column has that supporting capacity is high, the cross section is little, plasticity and good toughness, shock resistance are strong; Overall economic efficiency is good; Be used with high-strength concrete, can give full play to the high-strength concrete advantages of high strength, in engineering, have a wide range of applications.But; When adopting the reinforced concrete cast-in-situ beam slab, need to solve the connected node problem of steel core concrete column and reinforced concrete beam, general employing such as open reinforced hole, establish shear plate, methods such as light and shade bracket or twin beams leap; But above-mentioned bean column node difficulty of construction is big, process is loaded down with trivial details; The design and fabrication required precision is high, has brought very big workload for design and construction, thus node problems can solve be one of the key that promote of steel core concrete column.
The utility model content
The purpose of the utility model is to consider the problems referred to above and provides a kind of construction simple and convenient; Reasonable stress; Ultimate bearing capacity of joints is reliable, can guarantee that node adheres to specification, the perforate connected node of convenient and practical steel tube concrete frame puncheon and rc-frame-beam.
The technical scheme of the utility model is: the perforate connected node of steel tube concrete frame puncheon of the utility model and rc-frame-beam; Wherein steel tube concrete frame puncheon is provided with Liang Dong; The reinforced concrete Vierendeel girder passes from Liang Dongzhong, and along the outer wall of steel tube concrete frame puncheon the hoop beam is set.
Above-mentioned hoop depth of beam is identical with the height of rc-frame-beam.
The above and below of above-mentioned Liang Dong is respectively arranged with reinforcing ring.
The hole periphery of above-mentioned Liang Dong is provided with peg.
The hole cross sectional area size of above-mentioned Liang Dong is identical with the cross sectional area size of the rc-frame-beam that needs to connect.
Above-mentioned hoop beam includes vertical muscle and stirrup.
The utility model is provided with Liang Dong owing to be employed in steel tube concrete frame puncheon; Rc-frame-beam passes from Liang Dongzhong; And along the outer wall of frame column the structure of hoop beam is set, through verification experimental verification, all press the steel core concrete column test specimen of the utility model scheme perforate reinforcing; All there is not to destroy position in the reinforcement for openings of bean column node section; Its ultimate bearing capacity is compared with perforate steel core concrete column not, occurs reducing phenomenon, explain steel core concrete column with the connected node place of rc-frame-beam can reinforcement for openings.For the perforate steel core concrete column, after the bean column node tapping was taked effective strengthening measure, beam column reinforcement for openings node was a kind of bean column node of safe, economic, practical, easy construction.The utility model is that a kind of construction is simple and convenient, reasonable stress, and ultimate bearing capacity of joints is reliable, can guarantee that node adheres to specification, the perforate connected node of convenient and practical steel tube concrete frame puncheon and rc-frame-beam.

The specific embodiment
Embodiment:
The structural representation of the utility model is like Fig. 1,2,3, shown in 4; The perforate connected node of steel tube concrete frame puncheon of the utility model and rc-frame-beam; Wherein steel tube concrete frame puncheon 1 is provided with beam hole 2; Rc-frame-beam 3 passes from beam hole 2, and along the outer wall of frame column 1 hoop beam 4 is set.
The height of above-mentioned hoop beam 4 is identical with the height of rc-frame-beam 3.
The above and below in above-mentioned beam hole 2 is respectively arranged with reinforcing ring 5.
The hole periphery in above-mentioned beam hole 2 is provided with peg 6.
The hole cross sectional area size in above-mentioned beam hole 2 is identical with the cross sectional area size of the rc-frame-beam 3 that needs to connect.
Above-mentioned hoop beam 4 includes vertical muscle 41 and stirrup 42.
The utility model is when construction; Earlier will be with the steel tube concrete frame puncheon installation in position in beam hole 2; Then along the reinforcing bar of the outer wall colligation hoop beam 4 of steel tube concrete frame puncheon; And peg 6 is set at hoop beam and steel tube concrete frame puncheon junction, and again rc-frame-beam 3 is passed from the beam hole 2 of steel tube concrete frame puncheon, build the concrete of node area at last.
Through verification experimental verification; All press the steel core concrete column test specimen that this programme perforate is reinforced; All there is not to destroy position in the reinforcement for openings of bean column node section; Its ultimate bearing capacity is compared with perforate steel core concrete column not, occurs reducing phenomenon, explain steel tube concrete frame puncheon with the connected node place of rc-frame-beam can reinforcement for openings.For the perforate steel tube concrete frame puncheon; After the bean column node tapping is taked effective strengthening measure; Beam column reinforcement for openings node is a kind of bean column node of safe, economic, practical, easy construction, and the bean column node reinforcement for openings scheme of using in the design is feasible.
