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, this utility model tee girder column connected node, including multi-cavity steel tube concrete coupled column 1, And along the symmetrically arranged side plate in multi-cavity steel tube concrete coupled column 1 two side 2, set along one of side plate 2 Have and run through side plate 2 and be inserted therein the plate 4 of side multi-cavity steel tube concrete coupled column 1, prolong at two blocks of side plates 2 It is inserted with reinforced H profile steel combination beam 3 in the section of stretching and plate 4, constitutes tee girder column connected node.
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 the two pieces of ribbed stiffener 3-3, ribbed stiffener 3-3 arranged between the section steel flange of H profile steel 3-1 end It 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 There is the connector 3-5 flushed with H profile steel 3-1 edge a pair, in H profile steel 3-1 outside lower flange respectively It is welded with upper cover plate 3-2 and lower cover 3-4.Wherein, connector 3-5 is steel angle structure, the outer face of angle steel On bolt hole is distributed.Side plate 2 is provided with the through hole corresponding with connector 3-5 bolt hole with plate 4. The width of upper cover plate 3-2 and lower cover 3-4 is more than the width of lower flange in H profile steel 3-1.Ribbed stiffener 3-3 Three skirt solid weldings are used to be scheduled on the web both sides of H profile steel.Multi-cavity steel tube concrete coupled column 1 is by the warm at two ends Steel rolling tube composition sleeper and sleeper between web connect and compose with dividing plate, concreting wherein, two pieces Side plate 2 is fixed along multi-cavity steel tube concrete coupled column 1 both sides level, and two blocks of plates 4 are along sleeper both sides, two ends Laminating.
As shown in Fig. 3 (a)-(h), tee girder column connected node installation process of the present utility model is as follows:
(1) first plate 4 is positioned on the multi-cavity steel tube of multi-cavity steel tube concrete coupled column 1;
(2) according to plate 4 in the location dimension of the multi-cavity steel tube of multi-cavity steel tube concrete coupled column 1, many Have the vertical slot identical with plate 4 thickness on the web of chamber steel pipe, run through multi-cavity steel tube coagulation as plate 4 The passage of the side plate 2 of local soil type's zygostyle 1;Built-in inserted plate is inserted, uses spot welding to fixedly mount temporarily;
(3) on multi-cavity steel tube, position the installation site of side plate, side plate is adopted along long side direction with multi-cavity steel tube Connect fixing by angle welding;
Then plug welding mode is used to be welded together with side plate and multi-cavity steel tube by plate;Outside plate 4 disconnects Being two sections, the outer section of outside plate 4 uses twin fillet wolt mode vertically to connect along front side board, outside plate 4 It is fixing that inner segment uses plug welding to be connected with sleeper and both sides side plate;
(4) good for pre-assembly reinforced H profile steel combination beam 3 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 both sides side plate temporarily;Then by side plate and upper and lower cover plates And connector welding;
(5) by filling concrete in multi-cavity steel tube, the installation of T-shaped beam-column connection is completed.
As shown in Fig. 4 (a)-(c), for this utility model tee girder column connected node sectional view.
This utility model tee girder column connected node can improve its bearing capacity and energy dissipation capacity.And site operation Convenient, 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 row explanation this utility model T The mechanical property of ellbeam column connected 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. 5 (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. 5 (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. 5 (a), Internal Force Redistribution, The bearing power increase of structure;Along with the increase of external force, there is plastic hinge Fig. 5 (b) prior to side plate in beam cover plate B Shown in;Finally destroying as shown in Fig. 5 (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 tee girder column connected node uses multi-cavity steel tube concrete group Zygostyle girder steel U-shaped rigid joint form, uses the mode of post and beam-ends isolation, by full-height side plate with And the node connector that cover plate is constituted transmits beam-ends moment of flexure and shearing.When geological process, beam-ends is first Plastic hinge occurs, consumes certain seismic energy and form first earthquake protection line, back shroud plasticity occurs Hinge, dissipate seismic energy further, forms second earthquake protection line, and side plate ultimately forms plastic hinge, shape Become the 3rd road earthquake protection line.Overall structure meets the design principle of " strong column and weak beam, the weak component of strong node ", The energy-dissipating property of structure is relatively good.As shown in Figure 6, the hysteresis loop of node is full, does not has obvious pinch Phenomenon, 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.
