Key Points of Quality Control in Ball-Point Space Frame Project

1.Space Frame Engineering Quality Control Process

1.1.Space frame construction process

1.1.1.The process flow of space frame components processing

Raw material selection and inspection → cutting → grounding and welding → rust removal and coating → packaging, marking, storage and transportation.

1.1.2.Space frame installation and construction process

Check the base structure and embedded parts → measure and set off → sort and stack the space frame parts → test the compound size of the small unit on site → connect and install the support → install the lower chord, web and upper chord → check the first space frame→ in order Carry out the installation and inspection of each space frame→installation of roof panels and gutters → overall inspection of the space frame→cleaning→acceptance→dismantling of scaffolding → completion.


1.2.Quality control process of space frame construction

Preparatory work before the start of construction (joint review of drawings, implementation of the quality assurance system, construction progress plan and program formulation, new process and new material test) → construction report "Commencement Report" → construction unit chief engineer, supervisor approval → material inspection → process construction → quality Check, review and confirm the "Material Inspection Form" and "Procedure Inspection Form"→on-site quality control→completion report, as-built drawing and technical management data management→project quality assessment→individual project acceptance.

2. Quality control measures for space frame engineering

2.1.Reasonable establishment of project quality management organization

The project quality management organization must be established according to the characteristics, scale, and technical complexity of the project . The staffing must be professional and complete, the structure reasonable, and the quantity meet the needs of on-site management and management. The site must be equipped with necessary testing tools. On-site professional engineers are responsible for project quality control.

2.2.Compilation of perfect construction quality management rules

Before the start of the project, the project management agency should organize quality management personnel and technical personnel to formulate quality management implementation rules (plans) on a large scale according to the characteristics of the space frame project, clarify the procedures, measures, and methods of control during the construction process, and implement quality management during the process, Organize quality management work in strict accordance with the content and requirements of the quality management rules.

2.3.Contents of its quality management rules

2.3.1.Specify the personnel of the quality control organization, the quality requirements of each process - quality control procedures, methods and means, acceptance criteria, tests, quality control authority, etc.

2.3.2.According to the construction characteristics, set up key quality control points, including quality certificates of raw materials (steel pipes, bolt balls, sealing plates, cone heads, sleeves, high-strength bolts, etc.), key process inspections include measurement and setting out, and support connections, Chord and web installation, roof panel installation and completion inspection, etc.

2.3.3.List the expected quality inspection and prevention and control measures (including materials, network frame installation, etc., which are prone to quality problems).

2.3.4.Compile the quality assessment and acceptance form for each process of the space frame structure. The various construction quality inspection forms shall be handed over to the quality management personnel and the main operators, and implemented during construction . The quality work form shall use a unified and

Several cutting methods of steel structure space frame

图片
  Steel st ructure space frame s are now widely used, such as galvanized steel warehouse , glass dome building , airport hangar ,steel structure warehouses, hall roofs, gymnasiums, etc. The builder will cut, produce, and process according to the customer's requirements. There are many ways to cut steel structure space frame s, which will help you to have more choices of cutting. Then, the space frame   manufacturers below will give us a detailed description of several common cutting methods. The cutting methods of the steel structure space frame   are as follows: 1. Flame cutting by CNC machine tools: that is to say, use oxygen cylinders to oxidize and melt steel at a high temperature continuously. At present, natural gas is generally available, which is relatively reliable. 2. Waterjet cutting machine: Generally, high-pressure flowing water is used for cutting, and the accuracy is very high. It is often cut in some very thin, medium-thick steel that requires precision machining,

What are the advantages of steel over traditional concrete?

图片
  steel warehouse Steel structures offer several advantages over traditional concrete structures that cover a wide range of areas, including speed of construction, flexibility, sustainability, and more. Here are some common advantages of steel construction:   Lightweight and High Strength: Steel is a lightweight and strong building material. Compared to concrete, the use of steel reduces the dead weight of the building, which in turn reduces the load on the foundation and lowers the overall weight of the building.   Fast construction: Steel structures can be prefabricated in a factory and then simply assembled on site. In contrast, traditional concrete structures typically require more on-site pouring and maintenance time. As a result, steel structures are often faster to construct, helping to shorten project duration.   Design Flexibility: Steel structures are strong and malleable and can support large spans and diverse building designs. This gives designers more flexibility in creat

Lifting construction of the starting unit frame of the large-span arched space frame

图片
The space frame structure has good structural performance and a wide range of applications, especially for the installation of long-span steel structures. It has the advantages of saving steel, manufacturing technology, and convenient installation and construction. It is widely used in large-scale power generation facilities, petrochemical, coal f ields and other industries. In the construction of coal yards, in the past, most of the coal yards were piled in the open air, which caused great environmental pollution and affected the normal use of the coal yards. The coal raw material workshops of thermal power plants required relatively large building areas and spans (currently, the domestic span has reached 120m above), so that the steel space frame shell structure is widely used in the raw material dry coal shed workshop. The shell structure of the space frame of the dry coal shed has the characteristics of large span and high vertical height. During the construction process, it is ne
