How to reduce the amount of steel in steel structure?

The calculation of  steel structure engineering  quantity is a very complicated and huge project. There are many points that need to be paid attention to in the calculation process. A slight negligence may bring potential safety hazards to future  steel structure construction . Today, the editor of  Qingdao Yili Steel Structure Factory  is here to talk to you about 4 points for calculation of steel structure engineering quantities. I hope to give you some help! 1. According to the drawing catalog, clean up and check the number of drawings to check whether there are any omissions. 2. Statistics of doors and windows, indoor and outdoor steel ladders, roof color panels, daylighting panels, wall color panels, roof ventilators, rain sheds, downpipes, edge flooding parts, weather The amount of trenches etc. In the statistics, the materials, specifications and models of each material should be indicated. 3. According to the plan layout, elevation, section, and n...

el structural  members are generally stacked in the factory yard and on-site yard. Many people do not care about this aspect, and the construction site components are randomly placed, which greatly delays the progress of the project. So, what are the requirements for the stacking of  Qingdao Yili steel structural  members? Today, the editor of Yili Steel Structure will talk to you. 1. The stacking ground of the components should be level and solid, without puddles, ice layers, the ground should be flat and dry, and the drainage should be smooth, with better drainage facilities, and there are circuits for vehicles to enter and exit. 2. Components should be divided into areas according to type, model, and installation order, and vertical signs should be inserted. 3. The bottom cushion of the component should have sufficient supporting surface, and the settlement of the cushion should not be allowed. The height of the stack should be based on calculation, and the lowe...

Qingdao Yili Steel Structure Manufacturer  should arrange a special person to keep abreast of the climate forecast and grasp the rainy and climatic data in advance. Arrange a special person to check the on-site special items before the rain. For the places that do not meet the rain prevention measures or the standards are not standard, it is necessary to order subcontracting and rectification within a certain period. Especially with regard to the lightning protection measures, it is necessary to carefully and carefully conduct a full-scale review. Pay attention to the rain protection of the following parts: 1.  Steel structure  steel bar rainproof Protect the steel bars placed on site for a long time from rain and hide to avoid serious corrosion of the steel bars. Rebar storage site must have unobstructed drainage to avoid rainwater deposition and immersion of corroded steel bars. In principle, the welding of steel bars is suspended in rainy days. If welding is enc...

The  steel structure system  has comprehensive advantages such as lightweight, easy installation, short construction period, good seismic performance and less environmental pollution. These advantages mostly come from the raw materials of the  steel structure . The quality of the material determines the quality of the steel structure. In this issue, the editor and everyone divide the material requirements for steel structure production. I hope it will be helpful to friends who do steel structure engineering. 1. The steel materials, welding materials, coating materials, and fasteners used in the steel structure should have quality certificates and must comply with the design requirements and current standards. 2. In addition to the quality certificate issued by the manufacturer, the raw materials entering the factory shall be witnessed on-site, sampled, submitted, inspected, and accepted under the witness of Party A and the supervisor according to the contract require...

The  steel structure  you purchased has a long service life and durability. The versatility of steel as a  building material  has left a deep impression on you. In addition, you also like the idea of ​​reducing maintenance costs. However, only a little maintenance is required on a regular basis to ensure that your building remains strong and clean when it was first built. Let's take a look at how to protect steel structures? Remember to be careful when using ladders and climbing on the roof. The ladder should extend at least three feet above the roofline. The ladder must be level and firm. Secure the ladder to the building to prevent it from falling. If necessary, always help with others. Use a sturdy ladder that has been checked for damage and lose joints, and use a partner system to ensure safety. Be careful when you reach the roof. Put on heavy-duty rubber-soled work boots. Never walk on raised ribs, walk on the valley of the panel. Try to walk only by fixing the...

Judging the structure as the heavy steel structure and the  light steel structure  does not have the same scale, many experienced designers or project managers often cannot fully explain, but we can use some data to consider and judge: 1. Lifting weight of workshop: 25 tons or more, it can be considered as a heavy steel structure. Second, the amount of steel per square meter: greater than or equal to 50KG/M2, can be a heavy steel structure. Third, the thickness of the main component steel plate: greater than or equal to 10MM, less used for light steel structures. 4. In addition, there are some reference values: such as cost per square meter, maximum component weight, maximum span, structural form, eaves height, etc. These can provide empirical data when determining whether the plant is heavy steel or light steel. Of course, there are many now. The buildings are both light and heavy steel. However, there are some that we can be more sure of heavy steel: such as petroch...

How to connect the steel structure? The common connection methods of steel structure are welding, riveting, bolt connection (common bolt connection, and high strength bolt connection). The main classification of bolts. According to the performance level, bolts are divided into 3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and other grades. The bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel with heat-treated (quenched and tempered), which are commonly known as high strength bolts. For those bolts bellow grade, 8.8 are generally called common bolts. The numbers before and after the decimal point are respectively expressed as the nominal tensile strength and yield ratio of bolt material. common bolts Common bolts are commonly used hexagonal bolts, stud bolts, anchor bolts, etc., high-strength bolts are divided into torsion shear-type high-strength bolts and large hexagonal high-strength bolts. According to the force transmission method, bolts are ...
