Key points of large steel structure plant construction management, analyzed from the aspects of pre-construction preparation, steel structure fabrication, and installation process, pointing out the key points and methods of steel structure plant construction management. I. Supervision (management) control key points in the construction preparation stage (1) Establishment of project management team. It is necessary to select experienced, technically capable, responsible, and cooperative personnel according to the characteristics of the project. Professional matching is required, especially the selection of the general supervisor, who must have good professional quality and service awareness; at the same time, give full play to the role of various functional departments of the unit and select a suitable supervision organization form according to the project characteristics.

1. Thickening Isolation Method: Add insulation cotton to the roof of the steel structure plant. The insulation cotton commonly used on the roof is glass cotton, with common thicknesses of 50mm, 75mm, and 100mm, and a density of 10kg/m3. The insulation cotton board can isolate most of the solar radiation and conductive heat, reducing the greenhouse effect inside the room. This greatly reduces the temperature of the plant and improves the internal temperature of the steel structure plant. The color steel plate steel structure roof with added insulation cotton has the effect of being warm in winter and cool in summer. 2. Installation of ventilation facilities: Due to the heat and water vapor generated by some machines in the steel structure plant, if this heat and water vapor are not discharged in time,

In the design of steel structure curtain walls, detailed structural drawings need to be produced based on factors such as the size, color, and material of the stone. Then, according to relevant design specifications, the seismic resistance, compressive resistance, and other relevant parameters of the nodes need to undergo mechanical calculations to ensure the safety and stability of the steel structure curtain wall application. Conventionally, the selection of stone should be based on the indoor and outdoor characteristics of the curtain wall. According to the elevation drawings and detailed drawings of each node, mechanical calculations should be performed on various parameters such as strength, water absorption rate, and seismic resistance to determine the selection of stone. Priority should be given to the characteristics, color, physical properties, and texture of the stone products, while also combining the overall design.

Steel structures, owing to their inherent advantages, are widely used in modern buildings such as bridges, industrial plants, and high-rise buildings. However, numerous quality defects have been exposed in many construction projects involving steel structures. This article mainly discusses some opinions on the common problems and rectification measures encountered in the acceptance and completion acceptance of steel structure projects in recent years. I. Some Problems and Solutions in the Construction Process of Steel Structures 1. Problems in the Production and Manufacturing of Components The plates used for gantry steel frames are very thin, with the thinnest being 4 mm. For the cutting of thinner plates, shearing should be preferred over flame cutting, as flame cutting can damage the edges of the plates.

I. Preparatory Work Before Budgeting For a beginner, before making a steel structure budget, some knowledge is essential. First, you need to understand the construction process of steel structures, specifically how materials are received, cut, and constructed for each process. This will help prevent errors in later quantity calculations and highlight areas with higher material losses; you also need to learn steel structure construction standards, such as the arrangement, requirements, and quantity of column base plates; non-destructive testing; H-beam butt welds require non-destructive testing; knowing which is the H-beam flange and which is the H-beam web; the first-level weld of the flange requires 100% ultrasonic testing, and the second-level weld of the web requires 2

Current methods for reinforcing steel structures can be summarized as follows: 1) Increasing member section (such as steel bonding); 2) Improving structural force system (such as adding beams and columns); 3) Prestressed technology reinforcement method. Common methods for increasing the section size include increasing the section height, thickening the flange plate, and changing the section shape to a box section. The main reinforcement methods for increasing the steel structure section are steel bonding or carbon fiber cloth pasting. These two methods cause relatively little damage to the structure itself, and have developed relatively rapidly in China in recent years, with increasing applications. However, their applications in steel structure building reinforcement are relatively limited, especially...

Matters needing attention in the calculation process: 1.Regarding the format of engineering quantity calculation: 1.1The weight unit of steel structure is kg, the area unit is m2, and the length unit is m. The calculation results are all retained to one decimal place. 1.2When calculating the weight of components, the parts of the components can be numbered from bottom to top and from left to right, and calculated in this order. 1.3Format of the calculation formula: 1.3.1Plate: Specification × Length × Width × Quantity For example,-6×500×300×5 indicates that the plate thickness δ=6mm, the plate length is 500mm, and the width is 300mm

1. Strength: The ability of a component's cross-section material or connection to resist destruction. Strength calculation is to prevent the destruction of structural components or connections due to exceeding material strength. 2. Load-carrying capacity: The maximum internal force that a structure or component can withstand without being destroyed due to strength, stability, or fatigue; or the maximum internal force when a plastic analysis forms a failure mechanism; or the internal force when reaching a deformation that is unsuitable for continued load-bearing. 3. Brittle fracture: Generally refers to the sudden brittle fracture of steel structures under tensile stress without showing warning plastic deformation. 4. Standard value of strength: Yield point (yield strength) of steel specified in national standards
