Steel building structure engineering are mainly constructed with steel, mainly composed of steel beams, steel columns, steel pipes and other parts. Steel structure building centers are generally connected by welding, bolts, rivets, etc., which is a major form of building structure. Steel structure engineering is widely used in large projects because of its light weight and simple construction.
The selection of materials for steel structure building is combined with the investment cost, and suitable materials are matched according to different market demands to maximize the effectiveness of investment. If the pollution is becoming increasingly serious, low-grade plates should be used in the roof enclosure materials to ensure a long period of time and investment costs in the later period. There are also gutter materials. The recommended material for the inner gutter must be 304 # stainless steel, which is the same as the roof board. Costs can be saved in other ways.
The hoisting of steel structure shall follow the construction sequence of “center column, column beam and bottom beam”. In the middle of the house, a stable frame type system needs to be installed first, then it is pushed to both ends, and the remaining steel columns and steel beams are symmetrically installed.
To ensure the integrity of the steel structure engineering building can make the engineering building more humanized, facilitate the design scheme and construction of the next stage, and create a steel structure engineering combining technology and plastic arts.
Feature 1: high product prefabrication rate, low construction cost and short construction period.
In the steel building structure engineering, the steel structure coefficient is unified, and mass production and manufacturing are adhered to, which improves the degree of productization of building industrialization. The early production of the steel structure project has integrated the production and installation of raw materials, greatly reduced the capital construction cost, accelerated the project construction, and shortened the construction period by about 40%.
Feature 2: The steel structure can meet the requirements of superelevation and large span.
The steel structure is symmetrical, close to the anisotropic homogeneous body, with high compression strength and high modulus. Compared with glass, concrete and wood, its relative density ratio is much lower. Under the same compression conditions, the steel structure building weight is small, which can produce a large span, wide and high complex structure.
Feature 3: Raw materials can be recycled, which is conducive to environmental protection and sustainable development.
Steel is a kind of raw material with high strength, toughness and high efficiency, which has good recycling value. The angle steel can also be recycled without using a mold.
