  1.Decline in design quality The manpower and material resources required for steel structure design are much larger than that of general architectural design, and the design time limit is generally shorter, the design funds given are less, and the design tasks are larger. Therefore, steel structure Design tasks often have the problem of no one accepting them. Even if a design task is accepted, its design quality is often unsatisfactory. After contracting a project, the construction unit often subcontracts the steel structure design task of this project, because the construction unit rarely has the qualification for steel structure design, but because the design unit that subcontracts the project may also lack corresponding experience And talents, in this case, the steel structure design work often fails due to the confusion of the construction market. Moreover, due to the lack of corresponding supervision systems and legal normative documents, it is generally difficult to take measu

Since the 20th century, the spatial structure has been greatly developed all over the world. The space frame structure is a kind of space grid structure. The so-called "space structure" is relative to the "plane structure", which has the characteristics of three-dimensional function. The space structure can also be regarded as the expansion and deepening of the plane structure. Since the advent of the space structure, it has been welcomed by people for its high-efficiency mechanical performance, novel and beautiful form, and fast and convenient construction. In stadiums, convention centers, cultural facilities, transportation hubs and even industrial plants that require large spans and large spaces, space structures can be seen everywhere.   After a century of continuous development of space structure, in terms of structural form, in addition to space frame and reticulated shell, membrane structure, tensegrity system, open and close roof, and foldable structure are

Modern long-span space steel space frames are no longer limited to the traditional single structural form, and new structural forms and various combined structural forms are constantly emerging. Structural forms are becoming more and more complex. The "Bird's Nest" adopts a complex twisted space truss structure, the "Water Cube" adopts a polyhedral space rigid frame structure based on foam theory, the Olympic Badminton Stadium adopts the world's largest spanned string dome structure, and the Guangzhou International Convention and Exhibition Center adopts a stringed truss structure . Large-span space buildings such as "Bird's Nest" and "Water Cube" are very difficult to construct, because they are three-dimensional shapes and structural systems with spatial forces. The "Bird's Nest" is a hyperboloid saddle shape, with a high point of 68.5 meters and a low point of 40.1 meters. The plane is elliptical, with a long axis of

Requirements for anti-corrosion treatment of steel color plates in steel structure workshops:   1. The surface of the steel color plate on the roof of the steel structure workshop should be flat, and the welding slag, burr, rust, oil, etc. should be cleaned before construction;   2. The treatment method for the surface of the roof steel color plate of the steel structure workshop can be derusted by spraying or projecting, and derusting by hand and power tools;   3. The level of rust removal by spraying or projecting shall meet the following requirements: 1Sa1 level: the steel surface should be free of visible grease and dirt, and free of scale, rust and paint coatings that are not firmly attached; 2Sa2 level: There should be no visible grease and dirt on the surface of the steel, and the attachments such as scale, rust and paint coating have been basically removed, and the residues should be firm and reliable; 3Sa2 grade: There should be no visible grease, dirt, scale, rust and paint

With the advancement of social science and technology, there are more types of steel structure workshops . Different types of steel structure workshops can produce different effects. SAFS Steel Structure introduces the following six types of workshops.   1. Portal frame steel structure workshop The portal steel structure factory building is directly called the portal frame system. The main axis of the factory building is perpendicular to the horizontal plane, and the herringbone structure platform with a large diameter is used for clamping and working. This type of project is mainly used to process heavy and simple complete machines with large radial dimensions and small axial dimensions.   2. Spire steel structure workshop The steel structure factory building on the top is equipped with a general tailstock or a steel structure tailstock, which is suitable for the rotation of the long machine and the disc machine with a small diameter.   3. Double-span steel structure workshop The doub

       Steel structure processing building materials are the main materials used in the main project. The total weight of the building is light, and the steel structure residential system is light, which is about half of the concrete structure. It can greatly reduce the basic cost, and the environmental protection effect is also very good. In the process of steel structure residential construction, the number of sand, stone, and gray was greatly reduced. The materials used are mainly green, recyclable or degradable materials. When the building is demolished, most materials can regenerate or degrade without causing a large amount of garbage. Therefore, the biggest difference between steel structure processing and other metal processing is: 1.  Light weight of the steel structure: Although the steel structure is large, its strength is much higher than that of other building materials. Therefore, when the load and conditions are the same, the steel structure is lighter than other structu

  Some owners will associate color steel prefabricated houses with steel structure workshops , thinking that they are actually one type of building, but this idea is wrong. Yes, they have a lot in common, but there are also many differences. The following SAFS steel structure briefly introduces the differences in this respect.   First of all, the materials are different. The color steel prefabricated house is a mobile house with a light steel structure as the skeleton and a color steel composite board (also known as a color steel sandwich board) as the enclosure system. Steel structure houses use light steel keels as the skeleton, which has the characteristics of good toughness and strong load-bearing capacity, which can ensure the seismic performance of light steel houses; various composite materials are used as external wall enclosures to ensure house insulation, sound insulation, and fire prevention.   Secondly, their uses are also different: the prefabricated houses are easy to ass
