The size of the house is about the same size, and the foundation is mud. It is surrounded by a brick wall of slippery fiber 120. Now I want to build a cast-in-place slab about 3 meters high on it, which is used to put a 2-ton water tower...

The current foundation is definitely not stable, and I want to use wage steel as a cherry tree column, and then make a steel beam. How big of I-beam do you want to use, about how many are you?

Dear, according to what should not be overlooked when constructing a steel structure and refer to the following recommended easy guide: Consider using a 6-inch I-beam with about 3 hours of many roots. Vertical struts require at least 8 inches of I-beams, about 4 pieces.

In order to achieve the 2-tonne load-bearing requirement, it is crucial that the steel frames are installed correctly, and that they can withstand the pressure required for the holes to be struck. If possible, it is advisable to contact a professional steel structure company, they will provide more professional advice on construction.

The rapid development of steel structure has a 1951766170 impact on China

Kiss is a pleasure to answer for you, my answer is <> below

The impact of the rapid development of steel structure on China is that the development of steel structure industry in production, design, scientific research, supporting and other aspects is also basically perfect. The steel knot fighting hollow structure has green, energy-saving and environmental protection functions, and will become the development trend of China's residential buildings. China's housing construction has gradually become a pillar industry of the national economy.

1.Greatly save construction time, and the construction is not affected by the season; 2.Increase the usable area of residential space, reduce construction waste and environmental pollution; 3.

Building materials can be reused, driving the development of other new building materials industries; 4.Good seismic performance, easy to transform, flexible and convenient, bringing comfort to people and so on; 5.High strength, light weight, high safety and affluence of components, reduce the cost of buildings; 6.

In line with the national sustainable development strategy, low-carbon, green, environmental protection, and energy-saving are key industries supported by the state.

How to give full play to the advantages of steel structure and avoid the shortcomings of steel structure.

1. The advantages and disadvantages are relative, take the steel structure and concrete structure as an early liquid chain! In contrast, the steel structure has good plasticity, tensile resistance, bending and torsion resistance, good seismic performance, and the steel structure can achieve factory production, which greatly reduces the generation of construction waste, in addition, the steel structure installation cycle is shorter, and it is a green building material. 2. The disadvantage is that the overall cost of Lusun will be higher than that of the buried clear soil structure, and the process technology needs to continue to be popularized and developed.

3. The design mainly depends on the use of process requirements, the use of steel structure plasticity, can achieve large-span structure, can quickly assemble and other advantages, pay attention to aesthetic design in the design, etc., specifically in the actual design to add more experience.

3 All of them are mainly in the following aspects:

Steel structure residential building.

Large-span workshops.

Construction of light steel keel analysis frames.

In the development of villas, in low-rise and multi-storey residences, light steel structures such as cold-formed C-shaped steel or small hot-rolled steel can be used to form a keel structure system; High-rise buildings can be composed of hot-rolled H-type, welded H-type, welded box-type, cold-formed thin-walled square steel pipe filled concrete, round steel pipe filled concrete, etc.

Data Development:

Advantages of steel house. The light steel house is very safe and earthquake-resistant to 9 degrees. It can be typhoon-proof 12 and the roof is load-bearing with snow meters, this is because the steel keel is lightweight, strong, high-quality building material, and has good ductility and toughness.

The construction speed of light steel houses is very fast, and the construction period of a 200 house is within 1 month. This is because the parts of the light steel house are produced in the factory, and after being transported to the site, they can be directly assembled by the workers, so the time is very short.

The production of light steel houses has a high degree of industrialization and mechanization, and a high degree of commercialization. The main materials required for building a house are produced in the factory, and the raw materials are processed by machinery and equipment, which has high efficiency, low cost and good quality. Most of these equipment have introduced foreign advanced technology, and many large enterprises' new housing products have international quality.

80% of the materials of light steel houses can be reused. From the point of view of the main material, the steel will not grow insects or become rotten wood with the passage of time, and it can be reused after several years of demolition, which is very environmentally friendly and economical.

With the development of the economy, there are more and more steel structures. Especially for the plant with a more human span, the steel structure has the characteristics of less construction period, repeated use and good economic benefits than the concrete plant. The new steel is a new type of steel structure system, only with a high degree of standardization, flexible air arrangement, good seismic performance, industrialized production, short construction period, environmental protection and energy saving, etc., it has been widely used in North America and other places in the past 20 years, but it is mainly used in low-rise residences.

And in China, in order to extend the application scope of new steel structures to multi-storey residential buildings.

Steel structure building is a new type of building system, open up the real estate industry, construction industry, metallurgical industry between the industry boundary, set into a new industrial system, this is the industry is generally optimistic about the steel structure building system.

Compared with the traditional concrete building, the steel structure building replaces the reinforced concrete with steel plate or section steel, which has higher strength and better seismic resistance. And because the components can be made in factories and installed on site, the construction period is greatly reduced. Due to the reuse of steel, it can greatly reduce construction waste and be more environmentally friendly, so it is widely used by countries around the world and used in industrial buildings and civil buildings.

This can have, I feel that it should be an integrated kind of assembly, for example, the first few days said that 19 days to build a building, I feel that it is a trend, this should be structural, finished maintenance I feel that aluminum plate and the like can be used, but it cannot be regarded as an alternative material, I feel that steel structure should also have trade fairs and other expositions This can promote the industry.

In the application process of steel structure engineering, what are the ways to overcome its shortcomings.

In the process of steel structure engineering application, what are the ways to overcome its shortcomings? Hello, happy to answer your <>

The main methods of reinforcement of steel-friendly structures are: reducing the load, changing the structural calculation graphics, increasing the cross-section and connection strength of the original structural components, preventing the expansion of cracks, etc., and other reinforcement methods can also be used when there is mature experience. 1. Change the structural calculation graph

The reinforcement method of changing the calculation figure of the structure refers to the method of reinforcing the structure by changing the load distribution, force transmission path, joint properties and boundary conditions, adding additional members and supports, applying prestress, and considering the spatial coordination and balance work. 1.Before hoisting, without inspecting the components and correcting the deformation and fiber, they were blindly hoisted: 2

For transverse components such as tailstock and beam with long span or length, the position of the lifting point of the center of gravity is selected improperly when hoisting, and under the influence of the self-weight pressure of the component and the hoisting force, the component is unstable, resulting in bending moment, camber and deformation, and affecting the size of the steel structure installation; 3.Before the component is hoisted, it is not reinforced according to the requirements of the structural characteristics of the component; 4.When the component is vertically hoisted in place, it is found that the position is inconsistent, and the correct treatment measures are not taken, and the forced installation is carried out, so that the installed component does not meet the provisions of the design and specification.
