High-altitude in-situ installation of space frame structures

-

The high-altitude in-situ bulk technology and the high-altitude in-situ unit installation technology are two professional installation technology of the high-altitude installation technology of the space frame structures, The high-altitude in-situ unit installation technology is an improved version of the high-altitude bulk installation technology, Because of the faster construction period and the higher efficiency of the high-altitude in-situ installation technology，it’s more widely used in engineering construction. In-situ installation is to realize the high-altitude assembling and docking of the components by setting up a supporting platform or an aerial work platform according to the actual position of the component in space. The high-altitude in-situ bulk technology is to transport all unit components to the high-altitude operation platform through lifting equipment, and then carry out the steel bar butt construction on the high platform in turn. The size of the unit block should be determined according to the structural form and the lifting weight of the lifting equipment. The unit block should be divided reasonably and the lifting position should be accurate to ensure its structural stability and prevent irreversible plastic deformation of the unit block during the lifting process. Conditions that affect the installation quality and assembly accuracy of high-altitude in-situ units. The high-altitude in-situ unit installation technology has high construction efficiency, and the safety of the construction personnel on the high-altitude platform can be guaranteed, and the installation accuracy is high. However, the construction cost of the full-height frame of the operating platform is relatively high.

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...
