Description

Honeycomb web T-section special-shaped steel column

technical field

The utility model relates to the technical field of a novel building structure, in particular to a special-shaped steel column with a T-shaped cross-section of a honeycomb web.

Background technique

In residential buildings, special-shaped column structures have incomparable advantages over other structural systems, and are more and more favored by people. In recent years, they have been highly valued by scholars and engineers at home and abroad, and thus have been widely used.

However, in multi-story residential buildings, the reinforced concrete special-shaped column structure is difficult to meet the bearing capacity requirements due to the limitation of the length and thickness ratio of the column section, the crowded reinforcement in the node area, and the unsatisfactory seismic performance and difficult to deal with. The advantages of the special-shaped column cannot be fully reflected, thereby limiting its application range and making it difficult to promote. In order to overcome these deficiencies of reinforced concrete special-shaped columns, people have proposed all-steel special-shaped columns.

In the actual engineering of multi-story steel structure residences, the side columns usually adopt traditional solid-web type T-shaped cross-section special-shaped steel columns or truss-type T-shaped cross-section special-shaped steel columns. In order to meet the requirements of compressive bending mechanical performance, a larger section size is usually required. If a solid-web type T-shaped section special-shaped steel column is selected, the web shear strength will be much more abundant, but in order to ensure the local stability of the web, it is necessary to meet The web height-to-thickness ratio limit specified in the "Code for Design of Steel Structures" usually needs to increase the web thickness, which will lead to increased steel consumption and increased project costs, thereby increasing the overall cost of the project; if the truss type is selected T-shaped cross-section special-shaped steel columns, in addition to their limited shear bearing capacity, seismic performance and overall stability, the truss-type web members need to be welded with plates or strips, the construction is relatively cumbersome, and the connection workload is large, increasing The construction cost will also increase the overall cost of the project.

Utility model content

The purpose of the utility model is to improve the mechanical performance of the traditional solid-belly type T-shaped cross-section special-shaped steel column or truss-type T-shaped cross-section special-shaped steel column without significantly increasing the comprehensive cost of the project, so that the special-shaped column structure can be used in multi-high-rise residential buildings. To be more widely used in construction, a special-shaped steel column with a honeycomb web T-shaped section is provided.

The technical scheme adopted by the utility model is: a special-shaped steel column with a honeycomb web T-shaped section, including flat steel plate flange one, flat steel plate flange two, flat steel plate flange three, steel web one, steel web Plate 2 and the hole, one side of the steel web 2 is vertically connected to the middle of the steel web 1, the other side of the steel web 2 and the two sides of the steel web 1 are respectively connected to the Flat steel plate flange 1, flat steel plate flange 2, and flat steel plate flange 3 are connected together to form a special-shaped steel column with a T-shaped cross-section. The steel web 1 and steel web 2 are honeycomb-shaped with holes in the middle. Web, steel web two is composed of two steel plates with the same shape with notches on the edges, and the two steel plates are welded by butt welds to form a honeycomb steel web; It consists of steel plates with the same shape and a steel plate with notches on both sides of the edge. These three steel plates are welded by butt welds to form a honeycomb steel web.

Preferably, the hole form of the first steel web and the second steel web is circular, oval, square, rectangular, hexagonal or octagonal.

Preferably, the honeycomb web T-shaped section special-shaped steel column includes two types of equal-leg T-shaped section and unequal-leg T-shaped section.

The utility model is composed of the steel plate flange and the honeycomb steel web: first cut the steel plate used for the web according to a predetermined fold line or curve, and stagger half-wave butt welding to form a honeycomb web, and then combine with the wing The edge plate is welded.

The utility model can also be welded by honeycomb web H-shaped steel and honeycomb web T-shaped steel: first cut the webs of H-shaped steel and T-shaped steel according to predetermined broken lines or curves, and stagger the half-wave pairs respectively. The honeycomb web H-shaped steel and the honeycomb web T-shaped steel are respectively formed by welding, and then the two are welded to form.

In the section composition, the welding process and welding quality will directly affect the performance of the steel column. Therefore, the utility model needs to ensure a good welding process (pair welding process can be used); the "expansion ratio" of the steel column web ( Opening ratio) increases, the height of the section increases, the stiffness and radius of gyration increase, the slenderness ratio decreases, and the stable bearing capacity is improved. However, after the web is opened with holes, its shear performance will be affected to a certain extent. Therefore, in actual engineering, the "expansion ratio" or opening ratio should be controlled according to the actual stress situation.

The basic features of the utility model: increase the section height of the steel column in a more economical way, improve the rigidity and stable bearing capacity of the steel column; the section structure is reasonable, the mechanical performance is good; the structure is simple, the production and processing are convenient, fast, and labor-saving Saving materials will reduce engineering costs.
