Steel structure engineering reinforcement method

-

 What methods are used to reinforce steel structures? Let me tell you:

1. Enlarge the reinforcement of the component section

When using enlarged section to strengthen steel members, the selected section form should be conducive to the reinforcement technical requirements and consider the existing defects and damage. The reinforcement of steel structure engineering needs to be based on actual conditions. In many cases, different parts have different requirements for the quality of reinforcement. Therefore, steel structure engineering should choose appropriate reinforcement methods and conduct reinforcement at different parts.

2. Connection reinforcement and the connection of the reinforcing member

The connection method of steel structure includes welding seam, rivet, ordinary bolt and high-strength bolt connection method, which should be determined according to the reason, purpose, force condition, structure and construction conditions of the structure that needs to be reinforced, and considering the original connection method of the structure. . Steel structure engineering reinforcement should generally be connected by welding seams and friction-type high-strength bolts. When there is a basis, a mixed connection of welded seams and friction-type high-strength bolts can also be used. When welding is used for connection, the qualified welding process and connecting materials shall be used. The connection of steel structure can be divided into welded and non-welded parts. The welded part can be reinforced by welding seam, and the non-welded part can be reinforced by friction type high-strength bolts. If the steel structure engineering requires both of them to be reinforced,Mixed reinforcement can be adopted.



3.Crack repair and reinforcement

When the structure of the steel grid structure has an expansive or brittle fracture tendency due to repeated loads and improper material selection, structure, manufacturing, construction and installation, etc., it should be repaired.

Before repairing, it is necessary to analyze the causes of cracks and the severity of their effects, and take targeted measures to improve the actual work of the structure or to strengthen the structure. The components that are not suitable for repair and reinforcement should be removed and replaced. Due to the pressure of different loads on the steel structure space frame, many steel components are damaged to varying degrees.

Therefore, when the steel structure is a space frame, the damaged steel components can be replaced and then reinforced to improve the overall quality of the steel structure project.

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...
