The specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawing illustrated embodiment.
As shown in Figures 1 to 4, a kind of modularization node 6 for steel pipe column-H ellbeam connection, comprise the joint pin 1 of hollow setting, the two groups of internal partitions 3 up and down that are arranged at least one group of tie-beam structure 2 of joint pin 1 outer wall and are positioned at joint pin 1, the two groups of internal partitions 3 in up and down are annular internal partition, tie-beam structure 2 is H shape structure, and two groups of the up and down internal partition 3 upper and lower edge of a wing 4 of concordant H shape tie-beam structure respectively arranges.The spacing on lower two groups of internal partitions 3 district center planes equates with the spacing at 4 centers, tie-beam structure 2 edge of a wing.
Modularization node 6 adopts Technology of Steel Castings to make, and modularization node 6 structural entity are not laid weld seam.
As shown in Figure 6, cast steel modularization node 6 is welded to connect with beam column respectively by tie-beam structure 2 and joint pin 1, and internal partition 3 transmits the pressure at 4 places, upper bottom flange, and can improve the post jamb rigidity of node, prevents the excessive kink of bottom flange 4 on beam-ends.
Tie-beam structure 2 adopts H shape connector.The size of H shape connector is consistent with H ellbeam 8, and the corresponding steel pipe of the width of upper bottom flange 4 and height between the two post ?H ellbeam arranges.The number that arranges of tie-beam structure 2 is also determined according to the steel pipe column that needs to connect-H ellbeam, king post joint for frame construction, whole cast steel modularization node 6 is welded to connect by four tie-beam structures 2, for side column and corner post can be respectively tie-beam structure 2 by three and two correspondences be welded to connect.The size of joint pin 1 also with the consistent size of steel pipe column 7.In actual use, selected to determine by the engineer.
In the present embodiment, the upper and lower edge of a wing 4 is that round-corner transition is connected with joint pin 1 nodes domains.Nodes domains is the part between upper bottom flange 4 on joint pin 1.Fillet between the nodes domains of tie-beam structure 2 and joint pin 1 is avoided traditional beam column welding node because be in the brittle fracture that complicated applied force state and weld heat-affected zone cause at beam-ends, reduced the stress concentration degree in complicated applied force zone, make the control cross section of beam depart from the post jamb certain distance, the fillet between tie-beam structure 2 and nodes domains can also improve the rigidity of node in addition.
The fillet circular arc span of the upper and lower edge of a wing 4 and joint pin 1 nodes domains junction is by the manufacturing process determination of Foundry Works, under the prerequisite that can guarantee castability, arc radius is larger, Performance of Panel Zone is better, but because the difficulty of the larger casting of radius is larger, in the present embodiment, radius of corner is at least the twice of tie-beam structure 2 edge of a wing thickness.
In the present embodiment, the two groups of internal partitions 3 in up and down are that round-corner transition is connected with the junction of joint pin 1 nodes domains.Radius of corner is at least the twice of tie-beam structure 2 edge of a wing thickness.According to the casting technique requirement, in the manufacturing process of cast steel modularization node 6, the two groups of internal partitions 3 in up and down must be provided with and 2 casting of tie-beam structure could be realized, and the effective pressure on the transfer beams edge of a wing of two groups of internal partitions 3 arranging of the upper bottom flange 4 of concordant tie-beam structure.In the present embodiment, between the post jamb of the two groups of internal partitions 3 in up and down and cast steel modularization node 6, fillet is set, the same with fillet between nodes domains with tie-beam structure 2, fillet setting can be improved the rigidity of cast steel modularization node 6 herein.
As shown in Figure 5, in annular internal partition 3, square opening is set.And the wide thickness of column that is not less than 2 times of joint pins 1 of the plate of annular internal partition.Because the plate of internal partition 3 is wide larger, the performance of nodes domains is better, and the square opening aperture is larger, more is convenient to concrete perfusion in the steel pipe column 7.But due to the restriction of casting technique at present, the plate width of internal partition 3 is not less than the thickness of column of 2 times of joint pins 1, and after foundry method improvement in the future, larger internal partition width more is conducive to improve the performance of nodes domains.
In the present embodiment, the bight of square opening is fillet.The square opening that is arranged at internal partition 3 centers also adopts the mild transition of fillet in the bight, round-corner transition is to being conducive to the stressed smooth-going performance of whole cast steel modularization node 6.
In the present embodiment, the thickness of column of joint pin 1 is greater than the thickness of column of steel pipe column 7.Joint pin 1 wall ratio steel pipe column 7 is large, during load that structure is added, produce moment of flexure at beam-ends, moment of flexure is come balance by the pressure of upper bottom flange 4, pressure can make the node of bottom flange 4 correspondences on this-territory produce out-of-plane distortion, the thicker out-of-plane distortion of plate is less, is out of shape littlely to illustrate that rigidity is larger.Thereby can improve the rigidity of node.
Cast steel modularization node 6 shown in the present is the bending and shearing, pressure and the moment of flexure of post of transfer beams effectively.Whole node region is not laid weld seam, and the cast steel node Material ductility of Technology of Steel Castings moulding can be guaranteed.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and in the General Principle of this explanation is applied to other embodiment and needn't pass through performing creative labour.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not breaking away from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
