Steel structure is a structure that is mainly composed of steel materials, and is one of the main types of building structure.The structure is mainly composed of steel beams, steel columns, steel truss and other components made of steel and steel plates. Welds, bolts, or rivets are usually connected between components or components.Because of its light weight and simple construction, it is widely used in large -scale factories, venues, super high -rise and other fields.
Advantages and disadvantages of steel structure
Advantages of steel structure: The steel structure is very light, which saves great strength for the transportation of the steel structure.The strength pressure that the steel structure can withstand is great, and the capacity of the steel structure cannot be underestimated.Under the same conditions of the same conditions, the advanced technology used by the steel structure is made. Compared with other building materials, the weight is quite light and it is easy to transport. For engineering construction, it can be reduced to a large one.Pen fee.The steel structure of industrialized production is relatively convenient, and the production and installation time is relatively short. It can be seen that another advantage of the steel structure is that it is convenient for manufacturing.The energy saving effect of the steel structure is very good, which is also in a society that emphasizes energy saving and sustainable development.Disadvantages of steel structure: In the first aspect, it has good thermal insulation performance/heat resistance, but its fire prevention performance is weaker.If the temperature at home rises, the strength of the steel structure will decrease. If a fire occurs at home, the steel structure will collapse, and it is difficult to protect the safety of the family.The steel structure also has another disadvantage, that is, when the steel structure is in an environment with corrosive substances, he will be easier to rust.The beauty of the entire decoration.
Steel structure waterproof
First, apply the related waterproof coatings sold on the market on the surface of the related overlap joints.Be sure to lay the cut -cut special fabric when the coatings or humidity.Then apply another layer of waterproof coatings.Make the dedicated waterproof cloth more fully fit.The reason for doing this can also help polyester cloth can not be foaming or wrinkled.In addition, you can also use the coating to help the gap and the underlying waterproof coating to achieve the overall binding state, which is more stable and firm.After handling the coating of the waterproof area, you need to brush a surface coating.In this way, the preparation of steel structure waterproof projects is basically done.
Steel structural fire prevention
Steel structure waterproofing method: 1. Another layer of the outsourced layer is added to the outside of the steel structure. The generally selected materials are perlite, asbestos, etc.2. Filtering is a steel structure that is used in hollow, and is one of the most effective measures to prevent fire prevention.3. Blocked between the steel structure and placed some refractory materials. This is one of the most economical fire prevention methods.4. The expansion material is mainly to use the steel structure fire coatings we introduced above.It is currently our most advanced fire prevention technology.
Steel structure quotation
The cost per square meter of the steel structure is about 350-550 yuan.
Steel structure design
1. Determine whether the structure of the steel structure is usually used in the structure of high -level, large span, complicated body, load or crane with large vibration, large vibration, required activity or regular disassembly structure.Inleament: Building, gymnasium, and opera house 2. Structural selection and structure layout structure selection and layout are the qualitative structure. Because it involves extensive, it should be carried out under the guidance of experienced engineers.In the whole process of steel structure design, it should be emphasized that "Concept Design 3. Estimated that the section structure is finished, it is necessary to make preliminary estimates on the cross section of the component. It is mainly the assumption of the section shape and dimension of the beam pillars and support.Steel beams can choose groove steel, rolled or welded H -shaped steel section, etc. 4. Structural analysis Typical structures can directly obtain internal force and deformation of reference books such as checked mechanical manuals; simple structures are analyzed by hand calculation; complex structures only need to model models only need to be modeling.Run the program and do detailed structural analysis
Steel structure construction
I. Construction Line (1) According to the design requirements, according to the requirements of the drawings, in accordance with the Civil Construction Units, the clan construction unit will be verified and approved by the elevation and axis.(2) Before the construction, the nuclear axis of the latitude and weft meter is used to determine the elevation with the standards, and use the ink line to sign on the fixed fixed objects that are not easily damaged, indicate the elevation, and make a record.(3) After determining the axis and elevation, that is, after putting the big sample, then put a small sample, that is, to determine the connected side line and vertical cross axis of each steel column on the basic concrete, that is, the position of the pillar foot position of the door -type rigid standing frame positionEssence(4) When positioning the rigid rack, try to avoid the collision between the pillar and bolt of the rigid pillar to avoid the deformation of the bottom surface of the rigid columns.After that, the intensity loss brought by the bolt.2. Basic concrete embedded bolts (1) Before the basic concrete is poured, carefully check the size, length, elevation and location of the bolt, and fix the embedded bolts.(2) Before the basic concrete is poured, the butter and plastic film are wrapped in the silk port of the embedded bolt to avoid pollution to the bolt wire when the concrete is poured.(3) At the time of pouring concrete, there are experienced special persons on duty, and the effects of the positioning of embedded bolts when pouring concrete pouring.In order to avoid the displacement and elevation of the embedded bolt.
