Abstract

The invention discloses a concrete filled square steel tubular column and steel beam joint connecting structure, and belongs to the technical field of building structure engineering. The joint connecting structure comprises a concrete filled square steel tube, an H-shaped steel beam, two L-shaped plates and a supporting plate positioned below the H-shaped steel beam, the two L-shaped plates are symmetrically positioned on two sides of a web plate of the H-shaped steel beam, one outer L surface of each L-shaped plate is welded on the square steel tube, the other outer L surface of each L-shaped plate is connected with the web plate of the H-shaped steel beam in a bolted manner, one end of the supporting plate is a U-shaped inserting end, the square steel tube is provided with a jack matched with the inserting end, the inserting end is inserted into the jack and welded on the square steel tube, a vertical reinforcing plate is arranged at the bottom of the supporting plate, and the top of the supporting plate is connected with a lower flange plate of the H-shaped steel beam in a bolted manner. The joint connecting structure is higher in stability, and connectors are convenient to manufacture.

Description

The node connecting structure of a kind of concrete-filled steel square tubular column and girder steel
Technical field
The present invention relates to structural engineering technical field, in particular to the node connecting structure of a kind of concrete-filled steel square tubular column and girder steel.
Background technology
Girder steel-steel column connected node is one of important content of design of building structures, and girder steel-steel column connected node is the significant points transmitting bending moment and shearing, directly affects the load-carrying properties of overall performance under structure loaded condition and coupled component.At present, concrete-filled steel square tubular column and steel beam connecting joint mainly adopt that outer shroud is board-like, vertically-displacable, the board-like constant pitch point of grappling.The outer shroud gusset-type joint that in engineering, main employing performance is more excellent, but processing and fabricating is complicated, welding job amount is large, be inconvenient to construct, outer ring plate also affects attractive in appearance and usage space, these connected mode costs are high simultaneously, node for side column and corner post also attractive in appearance and structure can impact building, some structures are welded to connect plate in H profile steel beam end to be soldered on steel column by junction plate again, and moment of flexure is handed over large, poor stability.
Summary of the invention
A kind of connector is the object of the present invention is to provide to make simple, the concrete-filled steel square tubular column of stabilized structure and the node connecting structure of girder steel, to solve the problem.
For realizing the object of the invention, the technical scheme adopted is: the node connecting structure of a kind of concrete-filled steel square tubular column and girder steel, comprise and be filled with concrete square steel pipe, H profile steel beam, two L-type plates, be positioned at support supporting plate below H profile steel beam, two L-type plate symmetries are positioned at the both sides of H profile steel web, and L-type plate outer L face is welded on square steel pipe, another outer L face is connected with the web bolt of H profile steel beam; The one end supporting supporting plate is the insertion end of U-shaped, and square steel pipe offers the jack matched with insertion end, and insertion end is inserted jack and is welded on square steel pipe; The bottom surface supporting supporting plate is provided with vertical stiffener; Support the end face of supporting plate to be connected with the bottom flange crab bolt of H profile steel beam.
Further, described stiffener is clapboard, and the large end of clapboard is welded on square steel pipe.
The invention has the beneficial effects as follows, the web supporting H profile steel beam is connected by the L-type plate be welded on square steel pipe, support supporting plate simultaneously by inserting square steel pipe inside serves more firm support to H profile steel beam, the insertion end simultaneously supporting supporting plate stretches into the adhesion that can improve inner concrete and square steel pipe in square steel pipe, steadiness is stronger, and the connector of employing is easy to make.
Accompanying drawing explanation
Fig. 1 is the front view of the node connecting structure of concrete-filled steel square tubular column provided by the invention and girder steel;
Fig. 2 is the lateral view of the node connecting structure of concrete-filled steel square tubular column provided by the invention and girder steel;
Fig. 3 is the structural representation of support supporting plate provided by the invention.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 to Fig. 3 shows the node connecting structure of concrete-filled steel square tubular column provided by the invention and girder steel, comprise and be filled with concrete square steel pipe 1, H profile steel beam 2, two L-type plates 3, be positioned at support supporting plate 4 below H profile steel beam 2, two L-type plate 3 symmetries are positioned at the both sides of H profile steel beam 2 web, and L-type plate 3 outer L face is welded on square steel pipe 1, another outer L face is connected with the web bolt of H profile steel beam 2; The one end supporting supporting plate 4 is the insertion end 41 of U-shaped, and square steel pipe 1 offers the jack matched with insertion end 41, and insertion end 41 is inserted jack and is welded on square steel pipe 1; The bottom surface supporting supporting plate 4 is provided with vertical stiffener 42; Support the end face of supporting plate 4 to be connected with the bottom flange crab bolt of H profile steel beam 2.Stiffener 42 is clapboard, and the large end of clapboard is welded on square steel pipe 1, provides better support force, reduces moment of flexure.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
