The entire construction process of the steel structure space frame of the coal plant

-

       The steel structure space frame of the closed coal plant should pay attention to the production quality of the high -strength bolt friction surface as much as possible and maintain maintenance before assembly to prevent pollution and rust. Before the assembly, please perform the anti -slip index value test of the high -strength bolt friction surface, check the high -strength bolts to confirm and produce batch numbers at the factory, and use the high -strength bolt to produce batch numbers on time.

The high -strength bolt assembly requires that it can be worn casually and cannot be knocked and perforated; so it is necessary to prepare a certain amount of fetal shelf mold to adjust its deformation during the steel structure. This guarantees the stability of the specifications.

The stacked contact area should be flat when the steel structure is assembled, the contact area should be as good as 75%as much as possible, and the edge gap cannot be higher than 0.8mm. The high -strength bolt assembly production process, including operation order, installation method, tightening order, initial twisting, and final twist for strict control and inspection, and the torque wrench of screws should be corrected. The final twisting should be checked, and those who are not screwed or overgladed should be screwed or disassembled.

Custom -shaped coal factory spherical space frame rust removal and spraying is currently a link that is easy to ignore by steel structure engineering construction. Steel structure rust removal is divided into human resource rust removal and industrial equipment rust removal. Workers should be different according to the requirements of the sample diagram and the application of rust removal levels. The control of the quality control of the brush and coating should ensure that before the steel architecture is painted, the surface of the component of the brush should not have dirt, oil traces, water, and burrs. The frequency and thickness of the brush should reach the design points. There must be a qualified certificate for spraying raw materials. New projects of flame retardant application projects should be constructed.

The spherical space frame processing of a closed coal factory spherical space frame is light -like thick -wall pipe aluminum alloy profile. It has a lighter weight, high strength, and small occupying area. The prefabricated components are continuous, precision processing production and processing, automation control, integration of product specifications, tooling, and supporting. The overall scheme design, construction drawing plan design, computer simulation assembly, manufacturer production and processing, construction site assembly, etc. are carried out at the same time.

The raw materials of spherical space frame processing are relatively lightweight, and the assembly is simple. It only needs to be composed of manpower and no professional ability. Just keep the rules according to the construction drawings. It is an ideal choice for industrial production and civilian types, teaching buildings, etc. at this stage.

The application coverage is wide, and many of the FRP are used, and the air circulation is standardized. Buildings can be relocated and raw materials can be recovered and reused, which is not easy to cause waste. In line with the strategic planning of sustainable development concept.

The production of closed coal plants are welcomed by everyone with their ability to afford the characteristics, special methods, and fast and convenient work. In the large span, large -space sports venue, expo center, cultural facilities, transportation hubs, and even industrial factories, all the footprints of space planning are visible.

Grave design and structure construction construction distribution:

1. The overall lifting method, overall improvement method and overall lifting method of the overall lifting method on the ground;

2. Settles such as bulk foods in place, assembly assembly in the division level, and high -altitude movement in place.

In what areas are steel structures usually used

-

Steel structure manufacturers can process a wide variety of products, including the following categories: 1. Single and multi-story industrial and residential buildings. 2. Office buildings, primary and secondary schools, hospitals. 3. Luxury villas, tourism buildings. 4. Modern commercial buildings for various markets. 5. Mobile buildings (demountable buildings, emergency projects). The main building materials in membrane structure engineering are steel and membrane materials. For steel structures, the main processing flow includes: material feeding → cutting → inspection → assembly welding → rust removal → numbering packaging → factory. The precautions are: 1. Materials must have a material certificate. 2. According to the cutting length and rod specifications calculated by the designer, the rods are classified and stacked for easy construction in the next step. 3. According to the penetration size of the steel pipe, considering the influence of wall thickness and groove, the automa...

Three Methods of Space Frame Installation

  What are the 3 methods of space frame  installation ? SAFS steel structure professional technical staff share with customers and friends:   1.  Splicing the entire space frame  directly, after the completion  of  the corresponding ceiling method to hoist the entire space frame  into the air, and then within a certain hovering time, weld the space frame  in the corresponding position and connect it with the whole  building . This method is faster  to install, but has higher requirements for operators. 2.  The method is relatively mild, the space  frame works directly at a high place, and the space  frame is installed bit by bit through the part that intersects with the building, that is, starting from the surrounding area and completing the work at the final center point. The schedule  is very slow, but the operation difficulty is also reduced a lot. 3. This method is mainly applicable to the quadrangular pyrami...

Space frame has become one of the important fields of modern architectural structure

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...
