Description

Honeycomb web H-shaped steel column

technical field

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

Background technique

In recent years, the output, variety, and specifications of domestic steel and steel products have been greatly improved, and the design, manufacture, and installation of steel structures have been greatly improved. Steel structures have achieved extraordinary development in China.

Due to the shortcomings of reinforced concrete columns such as heavy weight and poor crack resistance, it is difficult to meet the requirements of bearing capacity and durability, thus limiting its scope of application; while steel columns have high strength, light weight, good seismic performance, and strong deformation capacity. , short construction period, good and rich architectural art expression ability, etc., are generally favored by architects. In the years of practice of traditional metallurgical industrial plants, high-rise and super high-rise and long-span structures, the outstanding advantages and functions of steel columns are almost irreplaceable.

Steel columns can be divided into two categories: solid-web type and lattice type according to the composition of their cross-sections. Relatively speaking, the solid-web column has a simple structure and is more convenient to connect with other components. Among them, especially the H-shaped steel, its cross-sectional area distribution is more optimized, the strength-to-weight ratio is more reasonable, it has the advantages of large section modulus, light weight, and steel saving, which can reduce the building structure by 30-40%; in addition, because of the H-shaped steel All parts are assembled at right angles to form components, which can save up to 25% of the welding and riveting workload. Therefore, it has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structure weight. widely used. However, with the development of multi-high-rise buildings, long-span structures, and heavy-duty factory buildings, the number of building floors gradually increases, and the upper load increases, which will inevitably lead to an increase in the cross-sectional size of the H-shaped steel column, thereby increasing steel consumption and improving the overall cost of the project. At this time, in order to save steel, the traditional method is to choose lattice steel columns. However, the cross-section of the latticed steel column is composed of single limbs connected by embroidered materials. The fabrication and construction are relatively cumbersome, and the workload of the connection is too large. Moreover, the bearing capacity and seismic performance of the oblique section are limited, especially the stability of the virtual and real axes. The large difference in performance leads to the inability of the materials to be fully utilized, which will inevitably increase the overall cost of the project.

Utility model content

The purpose of the utility model is to increase the section height of the steel column, improve the rigidity and stable bearing capacity of the steel column in a more economical way without increasing the steel material, and provide a honeycomb web H-shaped steel column.

The technical scheme adopted by the utility model is: a honeycomb web H-shaped steel column, including steel flange one, steel flange two and steel web, the steel web is arranged on steel flange one Between the steel flange and the second steel flange, the steel web is a honeycomb web with a hole in the middle. The steel web is composed of two steel plates with the same shape with notches on the edges. The two steel plates are welded by butt welds to form a honeycomb shaped web.

Preferably, the first steel flange and the second steel flange are steel plates, flat steel pipes, channel steels or I-beams.

Preferably, the opening form of the steel web is circular, oval, square, rectangular, hexagonal or octagonal.

For steel columns with H-shaped cross-section, they are usually mainly subjected to pressure. In practical engineering applications, they are mostly axial compression and compression-bending members. Bending strength and stiffness are the key factors affecting their bearing capacity. Therefore, under the premise of not increasing the amount of steel used, how to try to obtain greater flexural strength and stiffness, thereby obtaining a higher stable bearing capacity, has become the focus of attention. In this regard, the cross-section composition of the utility model is as follows: first cut the steel plate according to a predetermined fold line or curve, stagger half of the wave, make the wave crest face the wave peak, and form a honeycomb web with butt weld seam welding, and then join the flange The plate is welded. In this section form, the better the welding performance, the higher the bearing capacity of the H-shaped steel column. For this reason, the utility model needs to ensure a good welding process (pair welding process can be used); the "expansion ratio of the steel column section "(opening ratio) increases, the section height increases, its 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 utility model can also be formed by re-welding the H-shaped steel after its web is cut along a certain regular curve or broken line, or directly punched on the web of a large H-shaped steel.

The basic features of the utility model: increase the section height of the steel column in a relatively economical way, and improve the rigidity and stable bearing capacity of the steel column.

Beneficial effects: the steel column of the utility model has the characteristics of reasonable section structure, light weight, high bending rigidity, high bearing capacity, beautiful appearance and remarkable economic benefits, etc., and has broad development prospects.

Compared with the original H-shaped steel column, the H-shaped steel column of the utility model increases the moment of inertia and the radius of gyration of the section, and improves the rigidity and stable bearing capacity of the steel column.

Compared with the original H-shaped steel column, the H-shaped steel column of the utility model increases the section height, increases the section modulus, and improves the bending strength of the H-shaped steel column.

In the utility model, since the web has holes, it is convenient for the tie bars arranged in the filling wall to penetrate directly, so that the wall, the beam and the column are integrated, thereby improving the seismic performance of the structure.

The utility model greatly saves the amount of steel and the cost of paint and transportation due to the holes in the web, thereby reducing the comprehensive cost of the project and having strong social and economic benefits.

Since the utility model can open holes of different shapes according to the design requirements, compared with the traditional solid-abbed H-shaped steel column, the utility model has a more beautiful appearance.

The utility model reduces the self-weight of the structural layer without affecting the structural function and use, thereby reducing the cost of the foundation and foundation parts.

The utility model better solves the fireproof and anticorrosion problems of the steel structure without increasing the cost.

Compared with the lattice column, the utility model has simple structure of building components, convenient manufacturing and processing, can reduce manufacturing and processing costs, and reduce engineering comprehensive cost.

The utility model can provide key components for the development of a new steel structure system, and has a good transformation prospect.
