What does GHJ in steel structure mean? Isn t it what kind of profile?

1. According to the first chapter of the "Practical Steel Handbook" compiled by Zeng Zhengming, GHJ represents a kind of steel.

GHJ: Steel truss.

tz stairs; GTL steel ladder girder ;

TL ladder girder; GL steel beams (also commonly found in lintel numbers for concrete structures);

GTZ2 steel ladder column GL2 with number 2;

2. According to the first chapter of the "Practical Steel Handbook" compiled by Zeng Zhengming, it is a kind of profile, called steel truss.

Other profiles: structural steel.

This type of steel, due to its suitable hardenability, has a homogeneous sostenite, bainite or very fine pearlite microstructure after suitable metal heat treatment.

Therefore, it has high tensile strength.

and yield ratio (generally around the left), higher toughness and fatigue strength, and lower brittle transition temperature, which can be used to manufacture machine parts with larger cross-sectional dimensions.

The role of alloying elements in structural steel.

There are three aspects:

Increase the hardenability of the steel. Hardenability refers to the fact that when steel is quenched, it is hardened from the surface layer into martensite.

The depth of the layer is the main parameter to achieve good overall performance.

In addition to CO, almost all alloying elements such as MN, MO, CR, NI, SI and C, N, B, etc. can improve the hardenability of steel, among which MN, MO, CR, B have the strongest effect, followed by Ni, Si, Cu. Whereas, strong carbide forming elements such as V, Ti, Nb, etc., are only soluble in austenite.

The hardenability of the steel can be increased.

Affects the tempering process of steel. Because alloying elements can hinder the diffusion of various atoms in the steel when tempered, they can be compared with carbon steel at the same temperature.

In contrast, they generally play a role in delaying the decomposition of martensite and the aggregation and growth of carbides, thereby improving the tempering stability of steel, that is, improving the tempering resistance and softening ability of steel, and the effects of V, W, TI, CR, MO, and Si are more significant, while the effects of Al, Mn, and Ni are not obvious.

Steel containing a higher content of carbide forming elements such as V, W, Mo, etc., when tempered at 500 600, precipitate fine and diffuse special carbide points such as V4C3, MO2C, W2C, etc., to replace some coarser alloy cementite, so that the strength of the steel no longer decreases but increases, that is, secondary hardening occurs (see tempering).

Affects the strengthening and toughening of steel. Ni strengthens ferrite in a solution strengthening manner.

Mo, V, Nb and other carbide forming elements, both by diffuse hardening and by solution strengthening to improve the yield strength of steel.

Carbon has the most significant strengthening effect.

In addition, the addition of these alloying elements generally refines the austenite grains and increases the grain boundaries.

of the reinforcing effect. The factors affecting the toughness of steel are complex, and Ni improves the toughness of steel; MN is easy to coarse austenite grains and is sensitive to tempering brittleness; Reducing the P and S content and improving the purity of the steel play an important role in improving the toughness of the steel (see Metal Strengthening).

Hello, in general, GHJ refers to steel trusses, you can find the details in the corresponding master drawings.

Is it a "steel truss"? It depends on your drawings.

XG is for "tie rod".

The component code in the steel structure is generally named after the first special letter of the Chinese pinyin of the component name, and you can determine its meaning in combination with the structure of the component use part.

Another example is GJ is a "rigid frame"; GJZ is the "rigid frame column"; GJL is for "Rigid Frame Beam"; TL is for "joist"; lt is "purlin"; QL is for "Wall Beam". Wait a minute.

In the steel structure, XG represents the rigid horizontal source rod.

Steel structure is a structure that is mainly composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, etc., and the components or components are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large-scale factories, venues, super high-rise buildings and other fields.

Horizontal tie bar.

The tie rod in a tied arch bridge that is subjected to the horizontal thrust of the arch end is called a tie rod. It makes the arch end support not produce horizontal thrust, becomes a thrustless arch, according to the comparison of the stiffness of the tie rod and the arch rib, it can be divided into rigid tie rod and flexible tie rod. Rigid tie rods are subject to both tension and compression, while flexible tie rods are only subject to tension.

In the steel structure, XG represents the rigid horizontal tie rod.

XG stands for rigid tie rod, which is just a surface method of design, rigid tie rod you can define any name, the key is to express the drawing and meaning clearly.

Different drawings have different symbols to represent components. Typically:

XG, GXG: inside the tie rod.

ZC, SQC: inter-column support.

CC: The roof is vertically supported.

CG: Struts.

AT, LT, XLT: Pull strips.

LT, WL, L: Roofing purlins.

QL: wall purlins.

GZ, GJZ: steel columns.

KFZ: Wind Resistance Column.

Specifically, it should be judged in combination with the drawing and the position of the drawing where the symbol is located.

Steel Structure|G generation what.

Hello dear, glad to answer for you. In steel structures, G stands for high-strength steel. Common high-strength steels are Q345, Q390, Q420, etc.

Compared with ordinary steel, high-width historical strength steel has higher strength and stiffness, which can achieve better bearing capacity. In the design of steel structure, in order to ensure the structural safety and strength of the building, it is necessary to select the appropriate steel material according to the actual situation, and carry out the corresponding structural design and calculation. The G mark marks that the steel is high-strength steel, which needs to be designed and calculated in accordance with the relevant standards of high-strength steel to ensure the stability and reliability of the steel knot round field structure.
