The small flag is the field welding, v is the fillet weld, the square and circle are the weld positions, that is, ring welding and three-sided welding, and there is also a position symmetrical welding on the second diagram.
Steel structure drawings are drawings made for the construction of steel structures. Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components, which are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factory buildings, venues, super high-rise and other fields. Therefore, it is particularly important to understand the steel structure drawings.
What is a steel truss?
Steel truss refers to the roof structure of industrial and civil buildings made of steel, such as crane beams, bridges and hydraulic gates. Steel trusses are commonly used as the main load-bearing members. All kinds of towers, such as mast towers, TV towers and transmission line towers, often use space steel trusses composed of three-sided, four-sided or multi-sided plane trusses.

Steel trusses (steel truss) are trusses made of steel for industrial and civil buildings, such as crane beams, bridges and hydraulic gates. Steel trusses are commonly used as the main load-bearing members. All kinds of towers, such as mast towers, TV towers and transmission line towers, often use space steel trusses composed of three-sided, four-sided or multi-sided plane trusses.
What is a frame? What is a frame diagram?
It is a section that can fully express beam-column members on a plane. It is mainly shown as the shape of frame beam and column, the arrangement of steel bar, the arrangement of steel bar and the situation of lap Anchorage and so on.
It is usually used to describe the structure of a building; for example, it can fully express the section of beam-column members in a plane, mainly expressing the shape of frame beam-column, the arrangement of steel bar, the arrangement of steel bar, the situation of lap Anchorage and so on.
This is a Chinese character, pronounced as pn, which is rare in architecture. In the past, the general term wooden structure is now commonly used to refer to a flat structure, whether it is a steel structure, a wooden structure or a steel structure.
The basic meaning of
Quantifier: a truss is a truss; in a steel structure, the frame elevation usually consists of columns and beams.
Architecture: wooden frame was commonly used in the past, but now it usually refers to a plane structure, whether it is a steel structure, wood structure or steel structure.
Steel structure: in a steel structure, the frame elevation usually consists of columns and beams.

A frame association
Truss (truss): a structure in which members are connected to each other with hinges at both ends. A truss is a plane or spatial triangular element structure composed of straight bars. Truss members are mainly subjected to axial tension or pressure, which can make full use of the strength of materials, save materials, reduce self-weight and increase stiffness compared with solid beams when the span is large.
The advantage of truss is that members are mainly subjected to tension or pressure, which can give full play to the role of materials, save materials and reduce the weight of the structure. The commonly used steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, composite steel and wood trusses, composite steel and concrete trusses.
What is a truss?
The truss is a kind of frame structure welded with steel material, which has different components, namely the main pipe and the inclined pipe. Assistant manager and so on. It is a kind of steel frame which plays a certain role in strengthening the suspended objects. Not only that, he can also serve you to make full use of the strength of materials, and can examine materials more than other objects when the span is relatively large, so he is very suitable for load-bearing structures with large spans, such as satellite launch towers, crane frames, roof trusses and so on. However, when choosing its frame form, we should fully consider its no applicable points, such as its material, use, construction conditions and so on. If all are within the scope of satisfaction, it can best play its usefulness. Tripod truss, tripod truss is commonly used in tile roof truss, because its own chord internal force is relatively different, so the material consumption is very unreasonable, so it is used here for a long time. Trapezoidal truss, this type of truss is better than tripod truss members, and is long used in bridges and trestles. Polygonal trusses, also known as polygonal trusses, use less materials than other types of trusses, so they are the longest used trusses in engineering. Vierendeel trusses and vierendeel trusses are mostly taken from the shape of polygonal trusses. Its advantage is that there are few bars where the nodes are connected, so its construction is very convenient. Truss is something we will come into contact with in our home life, so for most people, it is an extremely unfamiliar word, because trusses appear a little in daily life, so some people call it “truss”. Perhaps some people will know that it is suitable for long-span factory buildings, gymnasiums and other public buildings.
What does truss mean?
A truss is a structure in which members are hinged at both ends of each other. The truss is a plane or spatial structure composed of straight bars with triangular elements. the truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized, and the material can be saved compared with the solid web beam when the span is large. reduce self-weight and increase stiffness.
From the mechanical analysis, when the shape of the truss is similar to the moment diagram of the simply supported beam, the axial force of the upper and lower chord is uniform, the axial force of the web is small, and the material is the most economical; from the material and manufacturing aspects, the wood truss is triangular, the steel truss is trapezoidal or parallel chord, and the reinforced concrete and prestressed concrete truss is polygonal or trapezoidal.
The ratio of the height to the span of the truss is generally specified in the design manual and code for the three-dimensional truss, the ratio of the height to the span of the truss, the three-dimensional truss, the three-dimensional arch, and the tensioned three-dimensional arch, respectively.
The truss has a wide range of use. When selecting the truss form, we should comprehensively consider the use, material, support mode and construction conditions of the truss. The principle of selecting the best form is to meet the requirements of use. Strive to minimize the amount of materials and labor used in manufacturing and installation.
The advantage of truss is that members are mainly subjected to tension or pressure, which can give full play to the role of materials, save materials and reduce the weight of the structure. Commonly used are steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, steel and wood composite trusses, steel and concrete composite trusses.
How much is the truss?
According to the market price in January 2020, the truss is between 60,150 yuan.
The word “truss” pronounces “h é ng”. Because the word “truss” is seldom used, it is mispronounced as “h á ng” (line), hence the name “rack”. Definition of truss: a braced beam structure formed by welding, riveting or bolting of members, which is called “truss”.
The advantage of truss is that members are mainly subjected to tension or pressure, which can give full play to the role of materials, save materials and reduce the weight of the structure. Commonly used are steel trusses, reinforced concrete trusses, prestressed concrete trusses, wood trusses, steel and wood composite trusses, steel and concrete composite trusses.
Extended data:
Form choice
Some reference values such as: cost per square meter, maximum component weight, maximum span, structural form, eave height, etc., these can provide empirical data in judging whether the plant is heavy steel or light steel.
National codes and technical documents do not have heavy steel, many buildings are light, heavy steel have. In order to distinguish the light building steel structure, it may be more appropriate to call the general steel structure “ordinary steel”.
Because the scope of ordinary steel structure is very wide, it can include all kinds of steel structure, regardless of load, even many contents of light steel structure, the technical specification for steel structure of light building only stipulates some more specific contents according to its “light” characteristics, and the scope is limited to single-story portal frames.
