1. Promote the development of energy saving in the construction industry
The application of steel structure construction technology in construction projects will help promote the green development of the construction industry and meet the needs of sustainable development. Facing the challenges brought by sustainable development, the construction industry bears the brunt, and energy saving and environmental protection become the theme. Under the guidance of this concept, building construction needs to choose more energy-saving and environmentally friendly materials. Steel structure construction technology is the main product of the development of construction industrialization. It can meet the construction quality and safety needs of construction projects, extend the durability and stability of buildings, and realize the great exploitation of resources.
2. Ensure the structural stability of buildings
The application of steel structure engineering construction technology can withstand the weight of cement concrete and has a strong bearing capacity. It can save material consumption and occupied space, reduce the cross-sectional area of the building, and avoid the total amount of steel structure exceeding the total amount of concrete. Even in the case of seismic disasters, it can effectively reduce the interaction of building materials, ensure the stability of the building structure, and improve the safety of the building.
The steel used in steel structure warehouses has excellent strength, such as commonly used I-beams, steel beams, etc., and can withstand huge weight. Compared with traditional building materials, steel has higher strength, which makes it easy to build large-span spaces in steel structure warehouses without requiring too many internal support columns, providing open and unobstructed space for cargo storage, which greatly facilitates large-scale equipment and bulk goods. The storage and handling of goods increases the actual usable area of the warehouse.
Steel structural members are transported to the site for assembly after being prefabricated in the factory. The construction process is relatively simple. Compared with traditional concrete buildings, time-consuming processes such as on-site pouring and maintenance are reduced. During installation, professional hoisting equipment is used to quickly complete the construction of the steel structural frame, greatly shortening the construction period. For warehouse projects that are in urgent need of putting into use, this can quickly create economic benefits and reduce losses caused by construction delays.
Its interior space is spacious and open, and can be flexibly arranged according to actual storage needs. Whether it is setting up multiple shelves to increase storage height or planning a large-area flat storage area, it can be easily achieved. Moreover, in the later use process, if storage requirements change, the transformation of the steel structure warehouse is relatively easy, and it is easy to adjust the internal layout and remove or add some structures to adapt to the storage requirements of different goods.
During the construction process of steel structure warehouses, relatively little construction waste is generated and has little impact on the environment. Moreover, the steel can be recycled and reused. After the warehouse reaches its service life, the demolished steel can be reprocessed and used in other construction projects, which is in line with environmental protection concepts. In addition, its good thermal insulation properties help reduce the frequency of use of air conditioners, heating and other equipment, reduce energy consumption, and achieve energy conservation goals.

Organized drainage is generally the rain roof drainage is divided into organized drainage and unorganized drainage (free drainage), Ben Chau clear thick island brother boundary rainwater drain down, the ditch that collects the rainwater is known as the gutter, gutter refers to the roof of the building.
The other is the eaves of the horizontal groove below the gutter that eaves gutter, used to receive the roof of the rain, and then by the general can not calculate the floor area, can be based on when led to the ground. Eaves gutter is divided into outer eaves gutter and inner eaves gutter.
Vegetable dew offerings, precipitation intensity and drainage speed to determine the size of the gutter ten small.
In order to let the rainwater can be very fast very smooth flow to the ground drain, generally take the middle of the high two sides of the low row on both sides of the house to leave a downpipe holes, so that it can be connected directly through the pipeline at the same time after the flower.
Gutters are first fastened to purlins, and after completing the roof panel installation, the picks are used to fasten the outside of the gutters to the roof panel, and the self-tapping nails (pull rivets) are sealed with structural adhesive. Stainless steel gutter is fixed with 2.0 galvanized iron sheet folded U-channel; color steel gutter is fixed with 2.0 galvanized iron sheet folded pieces.
The connection of the rainwater hopper should be fixed to the load-bearing structure of the roof. The connection between the edge of the rainwater hopper and the roof should be tight and leak-free. The diameter of the connection shall not be less than 100mm when the design does not require it.

A completed steel structure warehouse is a structure made of steel components that has been fully constructed and is ready for use. These warehouses are typically used for a variety of industrial and commercial purposes including storage, manufacturing, retail, and more. They are often constructed from pre-manufactured steel components that are bolted together on-site, but can also be customized to suit specific needs. Steel structure warehouses are strong, durable, and cost-effective, making them an ideal choice for many businesses.
Prefab steel Structure workshop buildings are used for industrial production in which all steel structures are painted and then delivered to the project site for installation. And because the steel structure can be manufactured in the factory and installed on-site, the construction time is significantly reduced. Due to the steel it can dramatically reduce construction waste and is more environmentally friendly. Therefore, it widely used in industrial buildings and civil buildings.
Steel garage doors are made of heavy-duty, real-gauge steel, which is hot-dip galvanized in zinc to protect against rust. Steel garage doors can have multiple layers that each add strength. The layers often include insulation, cladding, steel and a composite overlay. The composite overlay will determine the look of your door.
The prefabricated house is a kind of environmentally friendly and economical prefabricated house with color steel plate as the skeleton, sandwich panel as the enclosure material, standard module series for space combination, and bolted components for the new concept. It can be assembled and disassembled easily and quickly, realizing the general standardization of temporary buildings, establishing the concept of environmental protection, energy saving, fast and efficient construction, and making temporary houses enter the field of a series of development, integrated production, supporting supply, inventory and multi-turnover stereotyped products.
Steel structures are widely used in large-scale factories and arenas due to their light weight and simple construction. The requirements of steel structure are summarized for reference.
The quality control measures of steel structure project are as follows:
In the construction process of the construction site, the construction personnel occupy the main position in the steel structure operation. In this case, it is necessary to carry out specialized management for the participants of steel structure projects. In the actual management of steel structure project participants, it is found that the actual management work often fails to achieve the expected effect. Firstly, due to the uneven level of professional knowledge and comprehensive quality of the construction personnel involved in steel structure construction, they are not specialized steel structure construction personnel. Secondly, there are many problems in the management of steel structure construction personnel. The employees have loose attitude and poor discipline, which is not easy to be managed in a unified way. Facing this problem, the construction unit should formulate a corresponding management system to restrain them, and should not use conventional management methods. In addition, the pre-service education and training of employees should be strengthened to give full play to the enthusiasm of employees so that they can naturally comply with the rules and regulations.
In the process of engineering construction, more attention should be paid to the construction of construction quality control mechanism, to ensure the overall quality of engineering construction by perfecting the construction mechanism. First of all, the relevant units should improve the existing construction quality management mechanism, combine the problems that may occur in different construction links, and establish corresponding management and processing mechanisms. Secondly, pay attention to the construction supervision of steel structure. In the process of steel structure construction, many different types of problems may be encountered, and the corresponding processing mechanisms may be different. In order to save the construction time and reduce the construction difficulty, some construction personnel may adopt unreasonable construction methods in the construction process, but these methods cannot meet the construction requirements. Under the supervision of the supervisory unit. All the work can be carried out scientifically and reasonably, the probability of non-standard construction problems is greatly reduced, and the overall quality of the steel structure can be effectively guaranteed. The construction party should establish a sound supervision and management mechanism, encourage the relevant construction personnel to supervise each other, cultivate their sense of crisis and rigorous work attitude, and ensure the rationality of construction.
The quality of materials is directly related to the construction quality and is an important content of construction quality control. In the construction of steel structure project, the cost of steel structure material is very high. Strengthening the construction material management reduces the construction cost while ensuring the subsequent steel structure construction activities are carried out in an orderly manner. This requires comprehensive consideration of construction needs and selection of high quality and inexpensive materials. Specialists conduct in-depth market research, compare and analyze the materials, lay the foundation for more orderly implementation of subsequent steel structure construction activities, and effectively improve the construction quality of steel structure projects.
At the same time, the quality control of on-site steel structure components should be strengthened. First of all, check the samples provided by the permanent representatives and supervisors. If any problem is found, the factory should be notified at one time for correction and to ensure the quality of steel structure components can be transported. On the other hand, the steel structural members need to be inspected by the quality inspector of the supervisory unit upon arrival at the site.
What are the matters to be paid attention to in the fabrication, transportation, installation, fire protection and rust prevention of steel structure components?
