Big size steel structure warehouse steel frame buildings metal building

There are usually two types of metal buildings for large steel structure warehouses: one is a skeleton structure composed of cold-rolled thin-walled steel plates (with a thickness of less than 6 millimeters); One method is to use smaller section steel (such as angle steel, steel bars, flat steel, etc.) to make trusses, and then form a skeleton structure; There is also a skeleton structure composed of a mixture of two methods. The widespread use of thin-walled steel in the skeleton structures of automobiles, airplanes, and ships has promoted the development of metal buildings in industrial systems for large-scale steel structure warehouses. After World War II, the UK introduced the school building system of CLASP and SEAC large steel structure warehouses with steel frame buildings and metal buildings, while France introduced residential and office building systems of GEAJ and other large steel structure warehouses with steel frame buildings and metal buildings. Large steel structure warehouses, steel frame buildings, and metal buildings are lightweight, easy to industrialize, and have fast and convenient construction and assembly. They are particularly suitable for buildings that require rapid construction and need to be moved. They are commonly used in schools, residential buildings, offices, hotels, hospitals, factories, and warehouses. Silanized phosphating and zinc plating rust removal treatment must be carried out to improve the durability of later maintenance.

The structural form of metal buildings in large-scale steel structure warehouses is greatly influenced by the traditional European wooden frame construction, and is often replaced by thin-walled steel or small section steel combined into trusses to replace the wall reinforcement, joists, and rafters of wooden buildings. The combination of skeletons is generally related to building scale, production methods, construction conditions, and transportation capacity. Common ones include:

The unit component building system is composed of columns, wall reinforcement, beams, joists, purlins, rafters, and roof trusses, which are assembled into a large steel structure warehouse steel frame building metal building skeleton. Then, the roof is added, and wall panels and doors and windows are installed. The nodes of the skeleton are often fixed with bolts and connecting plates. In order to enhance the stability of the assembled skeleton, support or adjustable cross tie rods are added in necessary areas. Buildings assembled with unit components are flexible in assembly, convenient in transportation, and can meet the needs of various combinations of building spaces. But the on-site construction time is longer than other installation methods.

The frame partition style building system consists of a thin-walled steel keel frame partition fan, which is used as a load-bearing skeleton structure for walls, floors, and roofs to assemble the entire building. The internal and external insulation layers, thermal insulation layers, and doors and windows of this type of building can be installed during factory prefabrication, or can be installed on the construction site after the framework is assembled. This building system is like a prefabricated building made of panels, requiring fewer types of partition fans and convenient node assembly. Due to the fact that most of the work can be completed in the factory, the quality is higher and the on-site construction speed is faster. The box combination building system is assembled into a room sized box skeleton using thin-walled steel in the factory, completing interior and exterior decoration with an internal insulation layer. It can even install indoor decoration, including lighting fixtures, curtains, carpets, sanitary facilities, and even fixed furniture, in the factory. Upon arrival at the construction site, as long as each box is lifted and ready, the node structure and waterproofing treatment are done well, and the pipeline is connected, it can be used. Some box units are made into foldable box shaped components to reduce the volume during transportation, and when transported to the site, the components are opened for assembly during lifting. When assembling in this combination method, attention should be paid to stability, as well as waterproofing and insulation treatment of the joints. Some can also be made into trailer or containerized mobile houses for easy handling.
