Description

Technical Field

[0001] The utility model relates to the technical field of high-rise steel structure buildings, in particular to a round tube column node structure with a box-type corbel. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel frames and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly. Structural nodes are one of the main elements of the building structure system. Generally speaking, the components are limited to the maximum size of production or transportation, so the components that connect two or more fixed bodies are called structural nodes. At the same time, because of the large selection of node types, special node structures are sometimes deliberately designed to increase structural toughness or reduce structural internal forces.

[0003] Publication number CN114319606A discloses a steel structure node and a connection method thereof, including a node column and two sleeve parts respectively arranged at both ends of the node column; each sleeve part includes a plurality of connection plates evenly distributed along the circumference of the node column; each connection plate extends from the circumferential inner side of the end of the node column to the outside of the node column along the extension direction of the node column; a connection hole is provided on the connection plate; wherein the steel structure column matches the node column and can be sleeved on the sleeve part, and the steel structure column is provided with an outer hole corresponding to the connection hole, and the steel structure column and the steel structure node are fixedly connected by fasteners through the connection hole and the outer hole. A connection method for a steel structure node is also disclosed. This steel structure node is assembled by sleeve connection. Although the structure is simple and easy to assemble, for the steel frame conversion layer structure of a high-rise steel structure, this node structure is too simple to play a role in strengthening the strength of the node structure, thereby reducing the stability of the high-rise steel structure.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, the utility model discloses a circular tube column node structure with a box-type corbel. The circular tube column structure comprises: a circular tube column 1 and a box-type corbel 5.

[0030] There are at least three inner baffles 12, two of which are arranged at the head and tail of the column 11, and the remaining inner baffles 12 are arranged in the middle of the column 11. The inner baffles 12 are annular and have a through hole in the middle. In this embodiment, five inner baffles 12 are arranged in the middle part.

[0031] The first stiffening plate 13 vertically passes through the plurality of inner partitions 12 and is vertically arranged between two first stiffening plates 13. In this embodiment, the first stiffening plate 13 is located inside the column 11 corresponding to the connection between the circular tube column 1 and the H-shaped steel corbel 4 and the box-shaped corbel 5, and is staggered from the longitudinal weld of the column 11.

[0032] The spacing between multiple parallel inner partitions 12 is different. Inside the column 11 corresponding to the connection between the circular tube column 1 and the H-shaped steel corbel 4 and the box-type corbel 5, the arrangement spacing of the inner partitions 12 is smaller than the arrangement spacing at other positions, thereby improving the strength and structural stability of the connection.

[0033] In addition, in this embodiment, the first stiffening plate 13 in the column 11 can be assembled and welded by single-sided groove liner welding, and the weld is required to be fully penetrated. The inner partition 12 is welded from the middle to both sides. Due to the limited welding space of the inner partition 12, a de-assembly and de-welding process is required. At the same time, the groove of the inner partition 12 is opened on the side closer to the end of the column 11 to facilitate welding.

[0034] The circular tube column 1 is also provided with lug plates 15, which are symmetrically arranged at the head and tail ends of the column body 11, and the number is at least one pair. In this embodiment, four pairs of lug plates 15 are arranged symmetrically along the column body 11.

The supporting corbel 3 is connected to the bottom of the horizontal corbel 2. At least one H-shaped steel corbel 4 is provided, and at least two box-shaped corbels 5 are provided, and the box-shaped corbels 4 are provided on both sides of the H-shaped steel corbel 4.

[0036] like Figure 4 As shown, the box-type corbel 5 is provided with an inserting plate 52 , the box-type corbel 5 is connected to the outer wall of the column 11 through the inserting plate 52 , and the bottom of the inserting plate 52 is connected to the annular support plate 14 .

[0037] Among them, the box-type corbel 5 also includes: a box body 51 and at least two fourth stiffening plates 53 arranged inside the box body, the plug plate 52 is fixed on the box body 51, and at least the side and the bottom of the plug plate 52 are located outside the box body 51, the side is connected to the outer wall of the column 11, and the bottom is connected to the annular support plate 14.

[0038] The box body 51 includes: an upper end plate 511, a lower end plate 512, two side end plates 513 and a sealing plate 514. The lower end plate 512 is arranged parallel to the lower end plate 511, and the two side end plates 513 are vertically arranged between the upper end plate 511 and the lower end plate 512. The sealing plate 514 is located at the outer end of the box body 51, and the sealing plate 514 is sealed and connected between the upper end plate 511, the lower end plate 512 and the two side end plates 513.

[0039] The inserting plate 52 is disposed at the inner end of the box body 51 , and a portion of the inserting plate 52 is inserted into the box body 51 and fixed to the fourth stiffening plate 53 .

[0040] In this embodiment, the plug plate 52 is first assembled and welded with the column 11. After passing the flaw detection, the box body 51 and the plug plate 52 are assembled. A single-sided groove gasket is fully melted between the box body 51 and the plug plate 52. The sealing plate 514 of the box body 51 is sealed after the fourth stiffening plate 53 is welded.

[0041] like Figure 5As shown, the horizontal corbel 2 comprises: a top plate 21, a first bottom plate 22, a first through web plate 23 and a second stiffening plate 24. The first through web plate 23 is vertically arranged between the top plate 21 and the first bottom plate 22, and the second stiffening plate 24 is vertically arranged on both sides of the first through web plate 23.

[0042] like Figure 6 As shown, the supporting corbel 3 includes: a second through-web 31, a wing plate 32, a second bottom plate 33 and a third stiffening plate 34. The second through-web 31 is vertically arranged below the first bottom plate 22, and the wing plate 32 is arranged obliquely above the second through-web 31 and connected to the second through-web 31. The wing plate 32 and the second through-web 31 are connected to the bottom of the first bottom plate 22.

[0043] In addition, if there is insufficient welding space between the box-type corbel 5 and the H-shaped steel corbel 4, the box-type corbel 5 and the column 11 can be assembled and welded first, and then the H-shaped steel corbel 4 can be assembled. The inner sides of the box-type corbel 5 and the H-shaped steel corbel 4 are welded to the column 11 using a single-sided groove liner welding. The number of stiffening plates is not limited to the number mentioned in the above embodiment, and can be increased or decreased according to the situation.
