How to reduce the amount of steel in steel structure?

Steel structure engineering  is widely used in the field of  large-span structures . At present, steel structure roof leakage is the most common quality problem. When it is serious, it will affect the use of the building and cause economic losses to the owner. The following mainly summarizes the main causes of  steel structure roof  leakage and common anti-leakage measures from the design and construction aspects for reference. 1. Reasons for leakage in design (1) When designing the roof rainwater system, overflow measures were not set according to the specifications. Therefore, after the rainwater exceeds the system's discharge capacity, rainwater may overflow through the lap joints, resulting in leakage of the steel structure roof. Among them, the roof connected with concealed buckle and nailing board is very likely to have serious water leakage. (2) The lack of detailed design drawings such as the edging of the upper and lower cornices of the windows, the f...

The  steel structure workshop  possesses lots of advantages such as pretty appearance, bright colors, diversified building types, low cost, short construction period, highly industrialized production, easy installation and construction, flexible layout, and obtains the benefits of recyclable, light weight, uniform material, easy to design and convenient to calculate. The  steel structure building  has been increasingly used in modern industrial plants. But there is a shortcoming of steel structure workshop, that is non-fireproof. Although steel is non-combustible material, under the action of high temperature in an open flame, its mechanical index will change greatly as the temperature increases, and the bearing capacity and balance stability will decrease greatly with the increase of temperature. The decrease will be more obvious at about 500 degrees Celsius, and it usually collapses due to the loss of load-bearing capacity in about 15 minutes. This article wil...

Many companies and construction teams will be affected by wind load when installing  steel structures  on site more or less. If the local wind load is very big, then the construction will become much more hard and difficult. So what can be done to prevent or reduce the effects of wind loads? Let's follow the editor and find out! 1. I nstallation  C haracteristics of  P ortal  S teel  F rame  S tructure The on-site installation of portal  steel frame factory  is generally started from the position where the roof horizontal bracing is provided in the middle of the factory, and then spread to the surroundings for construction. During the installation procedure and construction, it is necessary to ensure the temporary stability of the steel beams and columns to prevent tipping. Temporary steel wire ropes are generally used for fixing. If there are horizontal supports and inter-column supports between installed stee...

With rapid economic development, industrial production workshops are in full swing around the world. Among them, the  steel structure workshop  has beautiful appearance, colorful colors, diversified building types, low cost, short construction period, the high degree of industrialization of steel component production, installation The construction is simple and the layout is flexible. At the same time, steel has many advantages such as lightweight, uniform material, easy design and calculation, and recyclability. It is increasingly used in modern industrial workshops. But the steel structure workshop also has a fatal flaw that is not fire-resistant. Although steel is a non-combustible material, under the action of open flame and high temperature, as the temperature increases, its mechanical index will change greatly, and the bearing capacity and balance stability will decrease greatly with increasing temperature, at about 500 degrees Celsius The decrease is more obvious, gene...

A complete set of  steel structure design  and construction drawings are generally divided into: 1. Drawing catalog List the numbers and names of newly drawn drawings, selected standard drawings or reused drawings. 2. General description of design The content should generally include: 1) Design basis for construction drawings; 2) The design scale and steel structure area of ​​this project; 3) The correspondence between the relative elevation of this project and the absolute elevation of the general map; 4) Description of indoor and outdoor materials and construction requirements, such as the strength level of bricks and mortar, the moisture barrier of the wall, the waterproofing of the basement, roofing, footing, scattered water, steps, indoor and outdoor decoration, etc. , You can also directly quote or add index symbols on the map); 5) Adopt new technologies, new materials or practices with special requirements; 6) Door and window table (if the type and ...

Deepening design refers to deepening the design, making the surface of the drawings appear, meeting the design and installation requirements of the connection nodes, and finally making the project smoothly implemented. It includes not only the content of the design, but also the material supply, transportation, installation methods, and sequence that the construction contractor cares about, and partly assumes the role of engineering consulting. The main content of deepening the design (1) Simulation analysis of the entire construction process For a long time, the simulation analysis of the entire construction process has been applied to the construction of  steel structures . With the increase of large-scale civil engineering, construction simulation has gradually become an indispensable part of large-scale complex engineering. (2) Structural design optimization In the simulation modeling analysis, the original  structural design  calculation model is ...

Many enterprise bosses have to do a design plan to customize the  steel structure factory  before building the steel structure factory, to perfect the structure of the steel structure factory structure graphics, and reasonable allocation of every inch of space. Steel structure workshops  generally require a professional designer to design a plan to carry out the construction. It is very necessary to select a professional engineering company to design the plan. Professional designers can consider the details of the construction of the Shijiazhuang steel structure plant in detail Situation, carry out comprehensive consideration, and make reasonable design of the plan according to the needs of the owner, so as to meet the corresponding design requirements The design plan of Qingdao Yili Steel Structure Factory needs to pay attention to the following items: Fire prevention: The steel components of the steel structure workshop are fireproof but not fireproof, so it is n...
