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 plug-in type beam support node, including H profile steel combination beam 3, and arrange
At the side plate 2 of both sides, H profile steel combination beam 3 edge of a wing, between biside plate 2, H profile steel combination beam 3 top flange
End face is provided with stiffener 1, is arranged with propping up of a default reinforcing plate between the side plate 2 of stiffener 1 both sides
Support square tube 4, constitutes plug-in type beam support node.
As shown in Fig. 2 (a)-(c), H profile steel combination beam 3 of the present utility model, including H profile steel, and
The two pairs of ribbed stiffeners 5 arranged in both sides, the H profile steel edge of a wing, and flush with lower flange in H profile steel, two pairs of ribbed stiffeners
5 are arranged on the biside plate edge being connected with the H profile steel edge of a wing.
As shown in Fig. 3 (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 45 ° of inclinations angle.Strengthen the width of side plate 4-2
Width more than supporting square tube 4-1.
As shown in Fig. 4 (a)-(b), this utility model plug-in type beam support node installation process is as follows:
First biside plate 2 is welded with H profile steel combination beam 3, then by stiffener 1 along biside plate centre position with
Biside plate weld, then by the supporting square tube 4 of default reinforcement side plate along stiffener 1 both sides according to 30 °-60 °
Inclination angle is inserted, and the cutaway portion meeting the left and right reinforcement side plate 4-2 presetting the supporting square tube strengthening side plate is oblique
The hypotenuse of limit and biside plate is fitted completely, then uses penetration weld mode that left and right is strengthened side plate 4-2 and both sides
Side plate is connected, and so far completes plug-in type beam support node and makes.
Apply at the Multi-cavity steel supporting plug-in type assembling as it is shown in figure 5, region shown in circle is this utility model
Pipe concrete coupled column support frame system schematic diagram.For supporting upper and lower cant beam and the water of this frame system
Flat-topped ridge supports.
This utility model plug-in type beam support node can improve its bearing capacity and energy dissipation capacity.Owing to existing in advance
Biside plate 2 is welded on reinforced H profile steel combination beam 3, and by the supporting square tube 4 of default reinforcement side plate along putting more energy into
Plate 1 inserts according to 45 ° of inclinations angle, the most at the scene by horizontal beam (H profile steel) and cant beam (supporting square tube)
Firm welding, which easy construction, does not damage multi-cavity steel tube concrete coupled column, saves material laborsaving.
Insert with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for row explanation this utility model below
Enter the mechanical property of formula beam support 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. 6 (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. 6 (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. 6 (a), Internal Force Redistribution,
The bearing power increase of structure；Along with the increase of external force, there is plastic hinge Fig. 6 (b) prior to side plate in beam cover plate B
Shown in；Finally destroying as shown in Fig. 6 (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 plug-in type beam support 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 it is shown in fig. 7, the hysteresis loop of node is full, there is no 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.
