Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further details.
As it is shown in figure 1, the supporting bilateral plate node of the overhanging cover plate of this utility model, including multi-cavity steel tube concrete coupled column 1, and it is horizontally fixed on the reinforced H profile steel combination beam 3 of multi-cavity steel tube concrete coupled column 1 side by two blocks of side plates 2, along institute State support upper cover plate 4 and being provided with two pieces of inclined angular distribution between the top of reinforced H profile steel combination beam 3, two blocks of side plates 7 Supporting lower cover 6, supporting square tube 5 inserts described support upper cover plate 4 and supports in lower cover 6, with reinforced H profile steel combination beam 3, Multi-cavity steel tube concrete coupled column 1 constitutes the supporting bilateral plate node of overhanging cover plate.
As shown in Fig. 2 (a)-(c), reinforced H profile steel combination beam 3 of the present utility model, including H profile steel 3-1, and at H The two pieces of ribbed stiffener 3-3, ribbed stiffener 3-3 that arrange between the section steel flange of shaped steel 3-1 end use three skirt to be welded on H profile steel 3- The web both sides of 1, are welded with a pair and flush with H profile steel 3-1 edge along the H profile steel 3-1 web both sides inside ribbed stiffener 3-3 Connector 3-5, is respectively welded upper cover plate 3-2 and lower cover 3-4 in H profile steel 3-1 outside lower flange.Wherein, connector 3-5 For steel angle structure, on the outer face of angle steel, bolt hole is distributed.The width of described upper cover plate 3-2 and lower cover 3-4 is more than H profile steel The width of the upper lower flange of 3-1.
As shown in Fig. 3 (a)-(c), multi-cavity steel tube concrete coupled column both sides of the present utility model are fixed with side plate 2, support Upper cover plate 4 and support lower cover 6 are fixed on two blocks of side plates 2 up and down in 30 ° of-60 ° of inclinations angle, wherein, support upper cover plate 4 and prop up Support lower cover 6 is provided with arcs of recesses groove structure for bottom.Support upper cover plate 4 and support the width of lower cover 6 more than supporting square tube 5 Width.
Side plate 2 is provided with the through hole corresponding with connector 3-5 bolt hole.It is easy to fix with reinforced H profile steel combination beam 3 Connect.Side plate 2 is the rectangular slab being provided with hypotenuse, and hypotenuse is located at two pieces of extensions being clamped in multi-cavity steel tube concrete coupled column 1 Top.
As shown in Fig. 4 (a)-(d), the installation process of the supporting bilateral plate node of overhanging cover plate of the present utility model is as follows:
1) first side plate 2 is positioned in the both sides of multi-cavity steel tube concrete coupled column 1, then use three skirt leg weld seam sides Side plate is welded together by formula with multi-cavity steel tube;
2) two pieces are supported upper cover plate 4-2 and supports lower cover 4-3 according to the angle employing angle welding mode and two set Side plate connects fixing;
3) reinforced H profile steel combination beam 3 good for pre-assembly is inserted between the side plate of both sides, will by tightening installation bolt Reinforced H profile steel combination beam 3 is fixed with biside plate temporarily, is then welded with upper and lower cover plates and connector by side plate;
4) supporting square tube 5 horizontal sliding inserted two support upper cover plates and supports between lower cover, using fillet weld seam mode Supporting square tube 5 is connected with a upper cover plate 4-2 and support lower cover 4-3, completes the peace of the supporting bilateral plate node of overhanging cover plate Dress.
Apply at the multi-cavity steel tube concrete supporting horizontal sliding assembling as it is shown in figure 5, region shown in circle is this utility model Coupled column support frame system schematic diagram.On the list support this frame system, diagonal brace supports with horizontal beam.
The supporting bilateral plate node of the overhanging cover plate of this utility model can improve its bearing capacity and energy dissipation capacity.Due in advance Two blocks of side plates 2 are provided with support upper cover plate 4 and support lower cover 6, then by supporting square tube 5 pushing style, and with insert at the scene Enter cant beam (supporting square tube 5) easy construction, do not damage multi-cavity steel tube concrete coupled column, save material laborsaving.
Below with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for the row explanation overhanging cover plate of this utility model The mechanical property of supporting bilateral plate node.
Utilizing ABAQUS software that node carries out finite element analysis, node post is the multi-cavity steel tube concrete group of 200x600 Zygostyle, beam uses the welding H-bar of H350x150x6x10, and at node, dual-sided board and cover sheet thickness are all same with flange of beam thick. Shown in Finite element analysis results Fig. 6 (a)-(c).
Owing to using multi-cavity steel tube concrete coupled column, steel pipe has stronger effect of contraction to concrete, shaft entirety Bearing capacity and ductility are relatively good, it is achieved that the design requirement of strong column and weak beam.Multi-cavity steel tube concrete coupled column girder steel U-shaped The destruction order of rigid joint is as shown in Fig. 6 (a)-(c) institute.When external force action is bigger, away from node bonding pad beam-ends A first Occur shown in plastic hinge Fig. 6 (a), Internal Force Redistribution, the bearing power increase of structure;Along with the increase of external force, beam cover plate B is prior to side Plate occurs shown in plastic hinge Fig. 6 (b);Finally destroying as shown in Fig. 6 (c) of structure, beam-ends edge of a wing flexing, upper and lower sides C is big for side plate Area is surrendered, but side plate does not forms plastic hinge, and structure still has certain energy dissipation capacity, and the design meeting the weak component of strong node is wanted Ask.
This utility model is according to conceptual Design of Earthquake Resistance principle, and structure should possess multiple tracks and provide fortification against earthquakes line, it is to avoid because of part structure Part destroys and causes integral system to destroy, and also requires that structure should possess intensity, good deformability and the power consumption of necessity simultaneously Ability.The supporting bilateral plate node of the overhanging cover plate of this utility model uses multi-cavity steel tube concrete coupled column girder steel U-shaped just to connect Joint form, uses the mode of post and beam-ends isolation, and the node connector consisted of full-height side plate and cover plate transmits Beam-ends moment of flexure and shearing.When geological process, first beam-ends there is plastic hinge, consumes certain seismic energy and forms first Earthquake protection line, back shroud plastic hinge occurs, dissipate seismic energy further, forms second earthquake protection line, and side plate is End form becomes plastic hinge, forms the 3rd road earthquake protection line.The design that overall structure meets " strong column and weak beam, the weak component of strong node " is former Then, the energy-dissipating property of structure is relatively good.As it is shown in fig. 7, the hysteresis loop of node is full, there is no obvious Draw shrinkage, node Energy dissipation capacity good, deformation is big, when coming earthquake, allows resident family have more escape time.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to Assert that detailed description of the invention of the present utility model is only limitted to this, for this utility model person of an ordinary skill in the technical field For, without departing from the concept of the premise utility, it is also possible to make some simple reasonings or replacement, all should be considered as Belong to this utility model and determined scope of patent protection by the claims submitted to.
