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 are provided with the through hole corresponding with connector 3-5 bolt hole.It is easy to be connected fixing with reinforced H profile steel combination bearing beam 3.Side Plate 2 is the rectangular slab being provided with hypotenuse, and the rectangular slab of two pieces of clamping multi-cavity steel tube concrete coupled columns 1 extends multi-cavity steel tube coagulation Local soil type's zygostyle edge, hypotenuse is located at the top of extension.
As shown in Fig. 4 (a)-(c), the supporting square tube 4 presetting reinforcing plate includes supporting square tube 4-1, and is located at support side The left reinforcement side plate 4-4 and right reinforcement side plate 4-5 of the left and right sides, pipe 4-1 end, and it is located at upper and lower both sides, supporting square tube 4-1 end Upper reinforcement cover plate 4-2 and lower strong cover plate 4-3;Wherein, left reinforcement side plate 4-4 and right reinforcement side plate 4-5 is that side, top cuts The rectangular slab at right angle, mono-the side laminating of cutaway portion hypotenuse and supporting square tube 4-1, relatively cut the end at the diagonal angle of right angle portions While be horizontally disposed with, supporting square tube 4-1 is retained as 30 ° of-60 ° of inclinations angle.Left reinforcement side plate 4-4 and the width of right reinforcement side plate 4-5 The degree width more than supporting square tube 4-1, the width of upper reinforcement cover plate 4-2 and the lower strong cover plate 4-3 width slightly larger than supporting square tube 4-1 Degree.
Supporting square tube 4-1 uses angle welding mode to be connected, so with upper reinforcement cover plate 4-2 and lower strong cover plate 4-3 respectively up and down After left reinforcement side plate 4-4 is connected with upper reinforcement cover plate 4-2 and lower strong cover plate 4-3 with right reinforcement side plate 4-5.
As shown in Fig. 5 (a)-(d), support plug-in type beam column supporting bilateral plate node installation process of the present utility model is such as Under:
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) 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;
3) supporting square tube of the default reinforcing plate made in advance is inserted between biside plate, meet to preset and strengthen side plate The hypotenuse of cutaway portion hypotenuse and biside plate that side plate 4-2 is strengthened in the left and right of supporting square tube is fitted completely, then uses penetration weld Left and right is strengthened side plate 4-2 and is connected with both sides side plate by mode, completes to support the installation of plug-in type 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 concrete supporting plugging in fitting Coupled column support frame system schematic diagram.On the list support this frame system, cant beam supports with horizontal beam.
This utility model supports plug-in type beam column supporting bilateral plate node can improve its bearing capacity and energy dissipation capacity.Due to Reinforcement cover plate 4-2 and lower reinforcement cover plate 4-3, left reinforcement side plate 4-4 and right reinforcement side plate it is provided with in advance on supporting square tube 4-1 4-5, then by the supporting square tube of this default reinforcing plate to tilt inserted mode insertion multi-cavity steel tube concrete coupled column sidepiece, and On-the-spot insertion cant beam (presetting the supporting square tube of reinforcing plate), which easy construction, do not damage multi-cavity steel tube concrete coupled column, Province's material is laborsaving.
Support with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for row explanation this utility model below and insert The mechanical property of formula beam column 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. 7 (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. 7 (a)-(c) institute.When external force action is bigger, away from node bonding pad beam-ends A first Occur shown in plastic hinge Fig. 7 (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. 7 (b);Finally destroying as shown in Fig. 7 (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, meets the design of the weak component of strong node 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 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.This utility model supports plug-in type beam column supporting bilateral plate node and uses multi-cavity steel tube concrete coupled column girder steel U-shaped Rigid joint form, uses the mode of post and beam-ends isolation, and the node connector consisted of full-height side plate and cover plate comes Transmission beam-ends moment of flexure and shearing.When geological process, first beam-ends there is plastic hinge, consumes certain seismic energy and forms the One earthquake protection line, back shroud plastic hinge occurs, dissipate seismic energy further, formed second earthquake protection line, side Plate ultimately forms plastic hinge, forms the 3rd road earthquake protection line.Overall structure meets setting of " strong column and weak beam, the weak component of strong node " Meter 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 obvious 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 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.
