As shown in Fig. 2 (a)-(c), reinforced H profile steel combination bearing beam 3 of the present utility model, including H Shaped steel 3-1, and the two pieces of ribbed stiffener 3-3 arranged between the section steel flange of H profile steel 3-1 end, ribbed stiffener 3-3 is welded on the web both sides of H profile steel 3-1, welds along the H profile steel 3-1 web both sides inside ribbed stiffener 3-3 It is connected to the connector 3-5 flushed with H profile steel 3-1 edge a pair, H profile steel 3-1 is divided outside lower flange It is not welded with upper cover plate 3-2 and lower cover 3-4.Wherein, connector 3-5 is steel angle structure, the outer end of angle steel Bolt hole is distributed on face.The width of described upper cover plate 3-2 and lower cover 3-4 is upper and lower more than H profile steel 3-1 The width on the edge of a wing.
As shown in Fig. 3 (a)-(b), multi-cavity steel tube concrete coupled column both sides of the present utility model are fixed with Side plate 2, side plate 2 is provided with the through hole corresponding with connector 3-5 bolt hole.It is easy to and reinforced H profile steel Combination beam 3 is fixing to be connected.Side plate 2 is the rectangular slab being provided with hypotenuse, and hypotenuse is located at two pieces and is clamped in Multi-cavity steel The top of the extension of pipe concrete coupled column 1.
As shown in Fig. 4 (a)-(b), the supporting square tube presetting reinforcement side plate includes supporting square tube 4-1, and Being located at the reinforcement side plate 4-2 of the left and right sides, supporting square tube 4-1 end, it is side, top that side plate 4-2 is strengthened in left and right Cut the rectangular slab at right angle, one the side laminating of cutaway portion hypotenuse and supporting square tube, relatively cut right angle portion The base at the diagonal angle divided is horizontally disposed with, and supporting square tube is retained as 30 ° of-60 ° of inclinations angle.Strengthen side plate 4-2 Width more than the width of supporting square tube 4-1.Use angle welding mode will strengthen side plate 4-2 and supporting square tube It is welded and fixed.
As shown in Fig. 5 (a)-(d), the installation of support plug-in type supporting bilateral plate node of the present utility model Process 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 welderings Side plate is welded together by angle welding mode with multi-cavity steel tube;
2) reinforced H profile steel combination beam 3 good for pre-assembly is inserted between the side plate of both sides, by tightening peace Reinforced H profile steel combination beam 3 is fixed by dress bolt with biside plate temporarily, then by side plate and upper and lower cover plates and Connector welds;
3) supporting square tube of the default reinforcement side plate made in advance is inserted between biside plate, meet default adding The hypotenuse of cutaway portion hypotenuse and biside plate that side plate 4-2 is strengthened in the left and right of the supporting square tube of strong side plate pastes completely Close, then use penetration weld mode that left and right is strengthened side plate 4-2 and be connected with both sides side plate, complete to support and insert The installation of formula supporting bilateral plate node.
As shown in Figure 6, region shown in circle is that this utility model is applied at the multi-cavity steel tube supporting plugging in fitting Concrete combination column support frame system schematic diagram.Cant beam and horizontal beam on the list support this frame system Support.
This utility model supports plug-in type supporting bilateral plate node can improve its bearing capacity and energy dissipation capacity.By On two blocks of side plates 2, it is provided with support upper cover plate 4 and support lower cover 6 in advance, then supporting square tube 5 is inserted Mode, and with insert cant beam (supporting square tube 5) easy construction at the scene, do not damage multi-cavity steel tube concrete group Zygostyle, saves material laborsaving.
Prop up with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for row explanation this utility model below The mechanical property of support plug-in type supporting bilateral plate node.
Utilizing ABAQUS software that node carries out finite element analysis, node post is that the multi-cavity steel tube of 200x600 mixes Solidifying local soil type zygostyle, beam uses the welding H-bar of H350x150x6x10, and at node, dual-sided board and cover plate are thick Degree is all same with flange of beam thick.Shown in Finite element analysis results Fig. 7 (a)-(c).
Owing to using multi-cavity steel tube concrete coupled column, steel pipe has stronger effect of contraction, shaft to concrete Overall bearing capacity and ductility are relatively good, it is achieved that the design requirement of strong column and weak beam.Multi-cavity steel tube coagulation The destruction order of local soil type's zygostyle girder steel U-shaped rigid joint is as shown in Fig. 7 (a)-(c) institute.Work as external force action Time bigger, first the beam-ends A away from node bonding pad occurs shown in plastic hinge Fig. 7 (a), Internal Force Redistribution, The bearing power increase of structure;Along with the increase of external force, there is plastic hinge Fig. 7 (b) prior to side plate in beam cover plate B Shown in;Finally destroying as shown in Fig. 7 (c) of structure, beam-ends edge of a wing flexing, side plate upper and lower sides C large area Surrender, but side plate does not forms plastic hinge, and structure still has certain energy dissipation capacity, meets the weak component of strong node Design requirement.
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 Partial component is destroyed and is caused integral system to destroy, also requires that structure should possess the intensity, well of necessity simultaneously Deformability and energy dissipation capacity.This utility model supports plug-in type supporting bilateral plate node and uses multi-cavity steel tube Combined concrete pole steel beam U-shaped rigid joint form, uses the mode of post and beam-ends isolation, passes through overall height The node connector that degree side plate and cover plate are constituted 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 occur, dissipate seismic energy further, forms second earthquake protection line, and side plate ultimately forms to be moulded Property hinge, formed the 3rd road earthquake protection line.Overall structure meets " strong column and weak beam, the weak component of strong node " Design principle, the energy-dissipating property of structure is relatively good.As shown in Figure 8, the hysteresis loop of node is full, does not has Significantly Draw shrinkage, the energy dissipation capacity of node is good, and 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 cannot be assumed that detailed description of the invention of the present utility model is only limitted to this, for this utility model art Those of ordinary skill for, without departing from the concept of the premise utility, it is also possible to make some letters Single reasoning or replacement, all should be considered as belonging to this utility model and be determined patent by the claims submitted to Protection domain.
