Otherwise, workers must lean out to tighten the flower basket bolts or climb up the ladder during installation, or wait for the installation of the purlins to be completed before climbing up the purlins and tightening the flower basket bolts, which is very unsafe. In addition, the arrangement position of the corner braces should also be considered, and do not fight with them when arranging horizontal braces. Steel structure engineering three, do not unilaterally consider factors such as "tension edge" and "compression edge" on the tension hole of the purlin, and drill holes with uneven upper and lower margins, because it is easy to install them in reverse during installation, and the result may be unfavorable. 4、 The corner panels for doors, windows, etc. cannot be generalized because during construction, you cannot guarantee whether the panels are located at the peak or valley of the profiled board. 5、 When working on large-scale projects, the detailed drawing numbering must consider the convenience of production, shipping, and installation. 6、 It is important to understand the true meaning of the "load and other data" provided by Party A, as they often do not understand these too specialized things. We need to put ourselves in others' shoes. Once the preliminary work is done well, the follow-up work will be much easier to carry out. 7、 The position of high-strength bolts should be reasonable, and consideration should be given to the construction space of the torque breaker and torque wrench. During installation, if the space is too small, the torque breaker and torque wrench cannot be in place, which may result in the inability to break the plum blossom head of the high-strength bolt or tighten the high-strength bolt. I have encountered designs that do not even provide the position of the sleeve. 8、 If possible, use a symmetrical bolt arrangement method for high-strength bolted connection plates. There was once a situation where there were 4 connections above and 6 connections below the intermediate point, and the workshop workers accidentally reversed some of them during assembly. I apologize for any inconvenience caused on site.

1. Surface cleaning of steel structures: The surface cleaning of steel structures is to ensure that there is no residual dirt, dust, etc. on the surface of the steel structure, and to ensure that the surface is thoroughly cleaned. 2. Surface treatment and verification of steel structures. All anti-corrosion treatments of steel structures are required to meet national standards. After surface treatment, the treatment results should be checked, and only those that meet the standards can proceed to the next work. 3. Choose a reasonable anti-corrosion construction plan. Different steel structures have different anti-corrosion methods depending on their usage environment. Therefore, when choosing anti-corrosion methods, various factors should be fully considered. 4. Spray construction of anti-corrosion paint for steel structures. When the surface treatment of the steel structure is qualified, it is necessary to spray anti-corrosion primer. 5. Reasonable storage of steel structures. After the anti-corrosion process of steel structures, they should be placed according to requirements to reduce damage. The above are the anti-corrosion methods for steel structures. If you want the service life of steel structures to be longer, these are necessary and also meet the standards..

With the gradual deepening of stability research, the above classification seems insufficient for components designed for axial compression, which is actually an initial bending point and the point of load application is inevitable. Therefore, in order to truly grasp the performance of this component, it is necessary to understand the impact of defects on it, and other components also have defects. On the other hand, in-depth research has been conducted on the post buckling performance of the components. 2、 The difference between strength and stability of steel structures. The strength issue refers to whether the maximum stress (or internal force) caused by the load of a steel structure or individual component is higher than the ultimate strength of the building material in a stable equilibrium state, which is a stress problem. The value of ultimate strength depends on the properties of the material. The maximum strength of brittle materials such as concrete is the maximum value, and the yield point of steel is often used. Stability issues are different from strength issues. The main finding is that there is an unstable equilibrium state between the external load and internal resistance of the structure, where deformation begins to rapidly increase, thus avoiding entering a state, which is a deformation problem. For example, due to the instability of axial compression, lateral deformation causes a larger bending moment inside the column, resulting in a much lower failure load than its axial compressive strength. Obviously, axial compressive strength is not the main cause of column failure.

There are three main reinforcement techniques for steel structures: 1) section reinforcement method: steel reinforcement is used locally or along the entire length of the component to connect it as a whole and share the force; 2) Change the calculation diagram: add additional supports, adjust load distribution, reduce internal force levels, force displacement of statically indeterminate structural supports, and reduce stress peaks; 3) Pre stressing cable method: using high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness, and stability of the structure.

The insulation material used for thermal insulation is mainly fiberglass cotton, which has good insulation effect. It is used for the insulation board of the exterior wall, effectively avoiding the "cold bridge" phenomenon of the wall and achieving better insulation effect. The thermal resistance value of R15 insulation cotton with a thickness of about 100mm can be equivalent to a brick wall with a thickness of 1m. Sound insulation effect is an important indicator for evaluating residential properties. The windows installed in the light steel system are made of insulated glass, which has good sound insulation effect and can achieve sound insulation of over 40 decibels; The wall composed of light steel keel and insulation material gypsum board can achieve a sound insulation effect of up to 60 decibels. Healthy dry work construction reduces the pollution caused by waste to the environment. The steel structure materials of houses can be 100% recycled, and most of other supporting materials can also be recycled, which is in line with current environmental awareness; All materials are green building materials that meet ecological and environmental requirements and are beneficial to health. The comfortable light steel wall adopts an efficient energy-saving system, with breathing function and the ability to adjust indoor air dryness and humidity; The roof has ventilation function, which can create a flowing air space above the interior of the roof, ensuring the ventilation and heat dissipation needs inside the roof. Fast and complete homework construction, not affected by environmental seasons. A building of about 300 square meters can complete the entire process from foundation to decoration in just 5 workers and 30 working days. Environmentally friendly materials can be 100% recycled, truly achieving green and pollution-free. All energy-saving measures adopt high-efficiency energy-saving walls, which have good insulation, heat insulation, and sound insulation effects, and can achieve a 50% energy-saving standard.

In buildings with special fire protection requirements, steel structures must be protected with refractory materials to improve their fire resistance level. Steel structures have poor corrosion resistance, especially in humid and corrosive environments, and are prone to rusting. Generally, steel structures require rust removal, galvanizing, or coating, and regular maintenance. Special measures such as "zinc block anode protection" should be taken to prevent corrosion of offshore platform structures located in seawater. 7. Low carbon, energy-saving, green and environmentally friendly, the demolition of reusable steel structure buildings produces almost no construction waste, and steel can be recycled and reused..

In this situation, the promotion and application of steel structures is considered one of the measures to resolve production capacity and promote industry structural adjustment. For example, at the press conference of the Ministry of Industry and Information Technology on July 22, Huang Libin said, "The Ministry of Industry and Information Technology will promote the use of steel structures and green building materials in rural areas, and promote the use of high-quality steel." It is reported that in addition to environmental advantages, steel structures also have the advantages of light weight, good seismic performance, easy construction, short construction period, and high industrialization level. Replacing reinforced concrete with steel structures may not increase steel consumption significantly, but it can promote structural adjustments in the steel and construction industries, which is beneficial for China's green and sustainable development. After the use of steel structures, they can be recycled and reused, which actually saves resources. On the other hand, steel structures mainly use steel products such as steel plates and H-beams, which have higher production technology difficulty and added value than threaded steel and other steel products. However, the implementation of steel structures in China has been relatively slow. Chi Jingdong introduced to reporters that nowadays, China's buildings are mainly reinforced concrete soil structures, and 50% -60% of the buildings in developed countries belong to steel structures. Currently, the amount of steel consumed in China's steel structures accounts for only about 5% of the total steel consumption. At present, the progress of promoting the use of steel structures in Guangzhou is still slow in China. Although it has been widely used in fields such as super high-rise buildings, large-span spatial structures, and industrial plants, there is still broad room for improvement in its use in residential and urban construction. The reason for the slow implementation of steel structures in our country used to be due to the shortage of steel supply, higher prices of steel structures than concrete, and gaps in production technology, types and specifications, equipment standards, and usage specifications of steel structures. The design, standard specifications, and supporting equipment of steel structure buildings are also incomplete. Nowadays, the technological level of steel has greatly improved, and the price of steel has dropped significantly. Correspondingly, the promotion of steel structures also has price advantages, which creates conditions for the promotion of steel structures.
