What difficulties should be paid attention to in the steel structure infrastructure project

The diversity of construction quality problems of steel structure engineering projects is mainly reflected in the variety of influencing factors that cause commodity quality problems, and the important reasons that cause commodity quality problems are also complex. Even if the same attribute of commodity quality problems, the reasons are sometimes different, so the understanding, judgment and treatment of commodity quality problems improve the diversity. For example, welding gap can not only appear in the weld metal, but also in the heat damage of raw materials, both from the surface of electric welding and the internal structure of electric welding; The gap can be welded vertically or vertically. The gap can be either cold gap or hot gap

What are the key points to pay attention to in the design of steel structure workshop

What are the key points to pay attention to in the design of steel structure workshop

The layout of roof truss support point system shall be determined according to the span of industrial plant, relative height, column spacing layout, roof truss structure type, crane tonnage and seismic intensity of the city. Generally, the roof truss structure with or without purlin system shall be provided with vertical support; In the system without purlin, the large roof panel has three points welded with the steel roof truss by electric welding, which can play the role of upwind support point. However, considering the impact of the project construction environment and installation, whether there is purlin or no purlin management system roof truss, the upwind transverse support point should be set on the steel roof truss and the upper chord of the skylight frame. For industrial plant or plant with steel roof truss spacing not less than 12m

Let's take a look at these matters in the construction of steel structure in rainy days

Let's take a look at these matters in the construction of steel structure in rainy days

During the construction of steel structures, there will be rainy days. At this time, what should we pay attention to in order to ensure the construction safety of the construction site in rainy days? The steel structure manufacturer will take you to have a look. 1. During the construction in rainy days, a temporary maintenance shed shall be set up, and the precipitation shall not be scattered on the hot melt welding. If the welding position is wet and cold, dry rags shall be used to wipe it clean. Before the welding, oxyacetylene flame shall be used to bake it to maintain the dryness of the joint without leaving water. 2. When lifting, if there is water on the prefabricated component, it shall be cleaned before construction, and the coating shall not be damaged. During installation, the prefabricated component shall be

Do you know the causes of steel structure damage

Do you know the causes of steel structure damage

The steel structure should be made of building steel as the main structure, characterized by steel columns, steel beams, truss structures and other prefabricated components made of steel and steel plates; The structure of welding, screw or riveting between components or components is one of the main types of building structures. If the steel structure is also damaged, we should find out and deal with it in time. Nanjing Tiandu Caigang summarized the following important factors for the destruction of steel structures in Nanjing: (1) insufficient structural bearing capacity due to load transformation, extended service, and changes in standards and technical specifications; (2) Prefabricated components are deformed, distorted, disabled, dented, etc. due to various accidents
