Space frame structure high-altitude installation channel protection

-

The four passages at the stairway, elevator, passage, and reserved opening of the space frame structures installation project are called the "four portals" of installation site. All of them must be protected in accordance with the requirements of the specification and warning signs should be set.


①The handrails of stairs or ladders should be installed in time, otherwise, 1.2m high temporary guardrails should be installed along the stairs or ladders to allow operation and passage.

②The elevator shaft head under installation and construction shall not be transported vertically except for elevator installation. The elevator shaft should be equipped with 1.2m high guardrail or movable door to be firm and reliable.

③ At the passageway of the installation site, when there is high-altitude installation work on the upper part, a protective shed must be erected. The width of the shed should be greater than the entrance and exit, and the length should be set according to the height of the building. The roof is covered with wood boards no less than 125px thick.

 ④The surroundings of the high-altitude installation work site, including platforms or pits, must be equipped with 1.2m high guardrails, and safety nets should be hung in accordance with regulations. Protective sheds should be set up near dormitories, offices, etc. around high-altitude installations. The roof of the protective shed is covered with wood boards no less than 125px thick to ensure the safety of people and buildings.

 ⑤ The closure and protection of the installation construction site shall be implemented in accordance with relevant safety and civilized construction management regulations.

I hope that the above five points should be kept in mind, and the construction staff should be carefully trained and read out these safety knowledge, so that the space frame construction will be more safe.

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 pyramid structure and the triangular pyramid structure. Each vertebral structure

  Coal storage facilities, including coal storage sheds, dry coal yards, and coal storage warehouses, have always been crucial in the coal industry. The application of steel structures and space frame technology is redefining the future of these coal storage facilities. These technologies not only enhance coal storage efficiency but also improve facility performance and sustainability. Challenges of Coal Storage Facilities: Coal storage facilities need to store large quantities of coal while ensuring it remains dry and of high quality. Traditional coal storage facilities often face issues such as coal dust emissions, inadequate humidity control, and maintenance difficulties. The application of steel structures and space frame technology offers new solutions to address these challenges. Advantages of Steel Structures: Steel structures play a pivotal role in coal storage facilities. Their high strength and flexibility make them an ideal material for supporting large-scale coal storage
