[0003] With the rapid development of my country's construction industry, steel and concrete composite structures have been widely used, and a lot of engineering experience and research results have been accumulated. Composite structure is an independent structural form composed of steel and concrete. Since the load-bearing section is not only reinforced concrete, but also the steel section works in a trinity with steel bars and concrete with its inherent strength and ductility, the composite structure has the advantages of greater bearing capacity, greater rigidity, and better seismic performance than traditional reinforced concrete structures; and compared with steel structures, it has the advantages of good fire resistance, good local and overall structural stability, and saving steel. Targeted promotion and application of such structures is of great significance to promoting the development of high-rise and multi-story buildings in my country, improving the overall seismic performance of the structure, and increasing the use space of the structure.

[0004] The crane beam is a beam structure that supports the operation of the bridge crane. There are crane tracks on the beam, and the crane travels back and forth on the crane beam through the tracks. At present, the current national standard drawings for reference in the design of crane beams are: "Steel Crane Beam (6m~9m)" G520-1~2, "Crane Track Connection and Car Stop" 05G525. The installation nodes in the drawings only specify the connection between the steel crane beam and the steel column and concrete column respectively, but do not specify the external steel bracket node sample when the steel crane beam is fixedly installed on the steel concrete column, steel tube concrete column, and steel concrete beam.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] See also Figure 1-13 The present invention discloses a composite structure cantilevered steel corbel node, comprising a composite structure with a built-in steel frame and a steel corbel 4 installed on the steel frame and used to support a crane beam, and a reinforcing component 5 is provided on the steel frame for reinforcing a connection node between the steel corbel 4 and the steel frame;

[0050] The reinforcement assembly 5 includes multiple first reinforcement members and multiple second reinforcement members. Each first reinforcement member is arranged at the top connection of the corresponding steel corbel 4 of the steel frame and extends to the side away from the steel corbel 4. Each second reinforcement member is arranged at the bottom connection of the corresponding steel corbel 4 of the steel frame and extends to the side away from the steel corbel 4.

[0051] The present invention proposes to arrange the steel crane beam on the combined structure, clarifies the node method of the cantilevered steel bracket 4 of the steel crane beam on the combined structure, opens up a new design concept and construction plan, provides a reference for similar engineering design and construction, and has great prospects for promotion and application.

[0052] It should be noted that the spacing between steel-concrete columns 1 and steel tube concrete columns 2 is 6 to 9 meters, and the setting of crane beams must meet the design and installation requirements of current specifications and drawings for steel crane beams.

[0053] In one embodiment, the steel corbel 4 includes a steel corbel upper flange 41, a steel corbel lower flange 42 and a steel corbel web 43 connecting the steel corbel upper flange 41 and the steel corbel lower flange 42, and a plurality of first stiffening ribs 44 connected to the steel corbel web 43 are also arranged between the steel corbel upper flange 41 and the steel corbel lower flange 42.

[0054] With this design, the first stiffening rib 44 strengthens the space between the upper flange 41 of the steel corbel and the lower flange 42 of the steel corbel, thereby improving the supporting effect on the crane beam.

[0055] In one embodiment, the composite structure is a steel-concrete column 1, which is composed of a steel column 11, steel-concrete column longitudinal reinforcement 12 and steel-concrete column stirrups 13 as a skeleton, and is poured with concrete. The corresponding steel bracket 4 is welded to one of the flanges of the steel column 11;

[0056] The reinforcement assembly 5 includes a plurality of outer transverse diaphragms 51 arranged between two flanges of the steel column 11 and arranged in an upper and lower arrangement. At least one second stiffening rib 52 connected to the web of the steel column 11 is arranged between two upper and lower adjacent outer transverse diaphragms 51 .

[0057] In this design, a plurality of outer transverse partitions 51 and second stiffening ribs 52 are arranged at the connection node between the steel corbel 4 and the steel column 11, thereby improving the bearing capacity and stability of the node area.

[0058] In one embodiment, a steel sleeve for connecting to the longitudinal reinforcement 12 of the steel concrete column is provided on the upper flange 41 of the steel corbel of the corresponding steel concrete column 1, and a connecting steel plate 6 for connecting to the longitudinal reinforcement 12 of the steel concrete column is provided at the bottom of the lower flange 42 of the steel corbel of the corresponding steel concrete column 1.

[0059] In this design, the steel sleeve is connected to the upper flange, and the connecting steel plate 6 is used to connect the longitudinal reinforcement 12 of the steel concrete column to the lower flange 42 of the steel corbel. The provision of the connecting steel plate 6 can avoid the use of the steel sleeve to connect to the lower flange 42 of the steel corbel, solve the limitation of the oblique cutting connection of the steel sleeve, and meet the requirements of the standard drawing set on the connection between the longitudinal reinforcement 12 of the steel concrete column and the steel beam.

[0060] In the specific implementation, the steel bracket 4 is pre-welded to the steel concrete column 1, the steel tube concrete column 2 and the steel concrete beam 3 in the factory, and the longitudinal reinforcement 12 of the steel concrete column is connected with the upper flange 41 of the steel bracket by a steel sleeve, which can effectively reduce the welding and weld quality inspection work at the construction site, prevent large discreteness of weld quality during on-site welding, ensure construction quality, improve construction efficiency, shorten construction period, save engineering construction costs, and have obvious social benefits.

[0061] In one embodiment, a connecting steel bar 7 for connecting to the steel concrete column stirrup 13 is provided between the first stiffening rib 44 of the corresponding steel concrete column 1 and the flange of the steel column 11 .

[0062] Such a design enables the steel-concrete column stirrups 13 to be installed in the blocking area of ​​the steel corbel 4 through the connecting steel bars 7, ensuring that the steel-concrete column stirrups 13 can be normally arranged there.

[0063] In one embodiment, the combined structure is a steel tube concrete column 2, which uses a steel tube as a skeleton and is formed by pouring concrete into the steel tube. When the diameter of the steel tube is greater than 700 mm and is within 2 m of the steel tube to be spliced, the reinforcement component 5 also includes a plurality of inner transverse partitions 53 arranged in the steel tube and a curved welded steel plate 54 for connecting the steel tube to the upper flange 41 of the steel corbel and the lower flange 42 of the steel corbel, and a concrete pouring hole is opened on the inner transverse partition 53.

[0064] By designing in this way, the curved welded steel plate 54 and the inner transverse partition 53 are arranged at the connection node between the steel corbel 4 and the steel tube concrete column 2, so as to improve the bearing capacity and stability of the node area.

[0065] In another embodiment, when the diameter of the steel pipe is less than 700 mm, since neither the human body nor the welding equipment can enter the steel pipe, the inner cross partition 53 cannot be welded inside the steel pipe. Therefore, the curved welded steel plate 54 is set as a complete circular steel plate, which facilitates welding while achieving the purpose of enhancing the bearing capacity and stability of the node area.

[0066] In one embodiment, the composite structure is a steel concrete beam 3, which is composed of a steel beam 31, steel beam longitudinal reinforcement 32, steel beam stirrups 33, steel beam waist reinforcement 34 and fixed steel bars 35 as a skeleton, and is cast with concrete on the outside, and the corresponding steel bracket 4 is welded to the web of the steel beam 31;

[0067] The thickness and width of the upper flange of the steel beam 31 are greater than those of the lower flange. A short square steel tube column 36 which is not penetrated by the longitudinal reinforcement 32 of the steel beam is arranged on the upper flange of the steel beam 31.

[0068] The reinforcement assembly 5 further includes a third stiffening rib 55 disposed on a side of the web of the steel beam 31 away from the corresponding steel corbel 4 and a plurality of fourth stiffening ribs 56 disposed on the third stiffening rib 55 and perpendicular to the third stiffening rib 55 .

[0069] Such a design facilitates the installation and fixation of the top of the crane beam by welding the square steel tube short column 36 to the upper flange of the steel beam 31. Since the upper flange of the steel beam 31 is reinforced compared with the lower flange, the area of ​​the steel beam longitudinal reinforcement 32 in the compression zone of the steel concrete beam 3 is reduced, and the steel beam longitudinal reinforcement 32 is prevented from passing through the square steel tube short column 36, thereby reducing the weakening of the square steel tube short column 36 and improving the local stability of the square steel tube short column 36. This improves the overall bearing capacity of the steel concrete beam 3 and the overall stability of the connection node, thereby having obvious social benefits.

[0070] It should be noted that after the crane beam is installed, a 50 mm thick concrete protective layer needs to be poured on the steel bracket 4 to meet the overall appearance requirements of the steel-concrete composite structural member.

[0071] A construction method for a composite structure cantilevered steel corbel node, comprising any one of the composite structure cantilevered steel corbel nodes, the method is as follows:

[0072] S1, welding the steel bracket 4 to the steel column 11, and after the welding of the steel bracket 4 is completed, sequentially welding the outer diaphragm 51, the second stiffening rib 52, the steel sleeve and the connecting steel plate 6 to the installation point;

[0073] Weld the steel bracket 4 onto the steel pipe, and after the welding of the steel bracket 4 is completed, weld the inner diaphragm 53 and the curved welded steel plate 54 to the installation point;

[0074] Weld the steel bracket 4 onto the steel beam 31, and after the welding of the steel bracket 4 is completed, weld the third stiffening rib 55 and the fourth stiffening rib 56 to the installation point in sequence;

[0075] S2, transporting the steel frame welded in step S1 to the construction site;

[0076] S3. After the steel frame is transported to the place, it is fixed and installed, and the node components are installed;

[0078] S5, pouring concrete in steel concrete column 1, steel tube concrete column 2, and steel concrete beam 3;

[0079] S6. Cast the 4th surface layer of steel corbel.
