Accompanying drawing explanation
Fig. 1 is girder steel of the present utility model-concrete column rigid joint organigram.
Fig. 2 is the structure overall schematic of the utility model node.
Fig. 3 is the structural representation of the utility model narrow edge of a wing H profile steel web.
Detailed description of the invention
As shown in figures 1 and 3, a kind of Novel steel beam-concrete column steel node, mainly comprise: with the box steel plate 1 of concrete column geomery adaptation, the web 2 be made up of H profile steel being welded in box steel plate inside, and be welded in the i beam 3 of box steel plate two relative side; Described web has two mutual vertical and integrated H profile steel, and described i beam is coaxial with H profile steel, and the end of i beam is provided with bolt hole.
In this embodiment, this joint structure is applicable to side column, corner post and center pillar.Make post indulge muscle to facilitate through by reasonably configuring narrow edge of a wing H profile steel structure, H profile steel web improves the shear capacity of node; the concrete that thin-walled box shape steel plate and the combination of narrow edge of a wing H profile steel give nodes domains forms effective constraint, meets the weak component shockproof requirements of strong node.Short girder steel welds in factory with box steel plate simultaneously, easily controls weldquality, makes its force transfer structure reach designing requirement.Girder steel subsequent installation junction stressed relatively little, junction plate high-strength bolt connects and can meet, also convenient construction.In addition this joint structure and concrete column can adopt prefabrication, field erected construction method, thus improve efficiency of construction and reduce on-the-spot pollution and wet trade.
In a further embodiment, described H profile steel is provided with to strengthen the through hole of Shear transfer between web and concrete.In this embodiment, the web of H profile steel can improve the shear resistance of nodes domains greatly, and web is worn the hole of some, can add the bonding of reinforced concrete and shaped steel, thus improves the anti-seismic performance of nodes domains.
As shown in Figures 2 and 3, a kind of architectural prefab, comprises the concrete column being provided with vertical muscle 105 and the girder steel-concrete column steel node be positioned on concrete column; Described girder steel-concrete column steel node comprises: with the box steel plate 1 of concrete column geomery adaptation, the web 2 be made up of H profile steel being welded in box steel plate inside, and be welded in the i beam 3 of box steel plate two relative side; Described web has two mutual vertical and integrated H profile steel, and described i beam is coaxial with H profile steel, and the end of i beam is provided with bolt hole; Have clearance portion between described H profile steel and box steel plate, vertical muscle, through described clearance portion, is filled with concrete in clearance portion.
In a further embodiment, described H profile steel is provided with to strengthen the through hole of Shear transfer between web and concrete.Described H profile steel, i beam and girder steel 103 is contour, and the narrow edge of a wing strengthens local compression and the tension of box steel plate; The end of described girder steel is provided with through hole, and i beam and girder steel are spirally connected fixing by frange plate connector 101, web connecting members 104.
In the above-described embodiments, in order to reach the raising girder steel-bearing capacity in concrete column reinforcing joint territory and the object of anti-seismic performance, ensure joint structure globality, box steel plate and the welding quality between narrow edge of a wing H profile steel and short steel I-beam need be paid special attention to, the requirement of welding for steel structure specification GB50661-2011 need be met.Pay special attention to the control of the width of H profile steel, require that both sides, the edge of a wing reserve post and indulge the space that muscle passes.
The utility model also may be used for fabricated construction, and in Specific construction process, this joint structure and concrete column are integral prefabricated in factory, field erected method, accelerates speed of application and quality.The reinforced concrete post that bean column node constructs and 1 floor is high is integral prefabricated.After transporting to building site, after prefabricate RC post hoisted in position, directly with high-strength bolt 102, the interlude of beam is in length and breadth connected with the end section of prefabricated girder steel.This prefabrication construction method is to the shortening construction period, and improve work efficiency, saving construction cost is extremely helpful.
This joint structure to be welded entirety by box steel plate and narrow edge of a wing H profile steel, powerful constraint is formed to nodes domains concrete, the narrow edge of a wing of its narrow edge of a wing H profile steel mainly facilitates post to indulge the through of muscle, also constrain concrete to strengthen globality simultaneously, also strengthen pressurized, the tension ability of steel plate bucket local in addition.The web of H profile steel also strengthens the shear resistance of nodes domains.See that this joint structure and concrete constitute local steel reinforced concrete structure on the whole, its anti-seismic performance is significantly improved.
In a word, the utility model provides a kind of joint structure mode of reliable girder steel-concrete column, makes girder steel be connected that power transmission is simple and reliable, easy construction with concrete; Meet the requirement of nodes domains anti-seismic performance simultaneously.
