With continued reference to fig. 9-10, as an embodiment of the present invention, the steel beam 3 is made of H-shaped steel, two vertical plates 6 are welded to two sides of the upper and lower flange plates, a first welding seam S1 is formed at the welding position of the flange plate and the vertical plate 6, and the other end of the vertical plate 6 is welded and fixed to the wall of the circular steel tube 1.
In order to prevent the influence on safety caused by the fact that the wall thickness of the circular steel tube 1 is thin and the circular steel tube is welded through, as an implementation mode of the invention, the circular steel tube 1 (usually one or two circular steel tubes at the edge of a wall column structure) welded with the vertical plate 6 is additionally provided with a local reinforcing sleeve 11 at the connecting section, and the local reinforcing sleeve 11 is a steel sleeve sleeved outside the connecting section of the circular steel tube 1 so as to increase the wall thickness of the circular steel tube at the welding area and improve the welding reliability of the circular steel tube 1 and the vertical plate 6.
Referring to fig. 11 again, in the invention, the upper and lower flange plates of the H-beam of the steel beam 3 are cut into circular arcs matched with the pipe wall of the circular steel pipe 1, so that the steel beam 3 can be in seamless butt joint with the circular steel pipe 1 when being connected, and the surfaces of the upper and lower flange plates can also be welded with the pipe wall of the circular steel pipe 1, that is, the circular arcs are welded and fixed with the pipe wall of the circular steel pipe 1, so as to form a second welding seam S2, as shown in fig. 10, so as to further improve the beam-column connection strength. The second welding seam S2 can be welded fully in the whole arc range, or only welded for one section or at intervals, and is designed according to the stress requirement.
Referring to fig. 9 again, the invention further welds and fixes the end face of the web of the H-shaped steel and the wall of the circular steel tube 1 to form a third weld S3, so that the full section of the steel beam 3 can be welded and fixed with the circular steel tube 1, and potential safety hazards caused by insufficient strength of the flange plates only welded and connected are prevented. Because the upper and lower flange plates of the H-shaped steel are cut into circular arcs, the end surfaces of the web plates can be tightly attached to the pipe wall of the circular steel pipe 1.
Through adopting the first weld zone between flange board and the riser, the second weld zone between flange board surface and the circular steel tube to and the third weld zone between web and the circular steel tube for the girder steel forms three-dimensional welded structure on the full section and between the circular steel tube, and welded structure's reliability is ensured to the at utmost, guarantees the security of nodal connection under the condition of simple welding and not with the help of stiffening plate, bolted connection, prevents that the node from leading to structural damage.
With continued reference to fig. 12-13, as an embodiment of the present invention, the circular steel tube 1 is provided with through grooves (not marked in the drawings) on the left and right tube walls of the connecting section, the positions and sizes of the through grooves are matched with the web of the H-shaped steel, the web of the H-shaped steel extends (as shown in fig. 11, the web is retained when the flange plate is cut, and the web is not cut) to pass through the through grooves, the web extends to pass through the circular steel tube from one side of the through grooves, and passes out from the other side of the through grooves to form the through plate 7, the through plate 7 passes through the circular steel tube 1, extends to the outside of the circular steel tube, and is welded and fixed with the outer tube wall of the circular steel tube, so as to form a third welding seam S3. Through adopting core penetrating plate and circular steel tube welded fastening, can greatly strengthen the nodal connection intensity of roof beam and wall post junction, core penetrating plate 7 tip and circular steel tube 1 welded fastening to core penetrating plate 7 forms the anchor with circular steel tube 1 behind the inside concrete filling of circular steel tube 1, can prevent the weak point of the simple welded fastening of beam-ends effectively.
In addition, the penetrating plate 7 is formed by extending the web plate of the H-shaped steel, namely the penetrating plate and the web plate of the H-shaped steel are of an integral structure, and compared with the prior art in which the penetrating plate is independently arranged, the penetrating plate has higher strength and firmer node connection. The end face of the H-shaped steel is cut in advance, the punching plate 7 is directly inserted into the round steel pipe, other structural plates, the punching plate or the bracket plate do not need to be additionally welded or bolted, the process is simple, and the construction is fast.
With continued reference to fig. 14-15, as an embodiment of the present invention, on the basis of forming the piercing plate 7, bolt holes (not marked in the figures) are further formed in the inner and outer tube walls of the connecting section of the circular steel tube 1, and the piercing plate 7 is correspondingly formed with bolt holes, and a bolt 4 is used to penetrate through the piercing plate 7 from one tube wall of the circular steel tube 1, and is fixed on the circular steel tube 1 through a nut at the other tube wall. Bolt 4 passes behind circular steel tube 1 and fixes on circular steel tube 1 through the nut, and bolt 4 forms the anchor in circular steel tube 1 behind the 1 inside concreting of circular steel tube, because bolt 4 passes through core plate 7 perpendicularly, and bolt 4 that the anchor is fixed forms the drawknot effect to core plate 7, can greatly strengthen beam column nodal connection intensity again, prevents because rare meeting under the loading effect welding seam destroy, the broken roll-off that leads to crossing core plate 7 and shake off from the circular steel tube, the node is inefficacy.
It should be noted that, although the vertical plate 6 is connected with two circular steel tubes 1 in the drawing, it is foreseen that the vertical plate 6 can be completely welded and connected with more circular steel tubes 1 by lengthening according to the design requirement; although the illustrated piercing plate 7 only penetrates one round steel pipe 1, it is obvious that more round steel pipes 1 can be penetrated as needed to form an anchor with more round steel pipes 1.
In the invention, the diameter of the round steel pipe 1 is 100-300mm, and the wall thickness is 2-10 mm; the distance between the circular steel tubes 1 is 50-500mm, so that the bearing capacity of the structure can be guaranteed, the material consumption can be greatly reduced, the cost can be saved, and the transportation is convenient.
