Steel structure light floor slab
Steel structure light floor slab was a kind of board used in construction. It has many advantages, such as high strength, good bearing capacity, and high bearing capacity per square meter. It is suitable for building floors in places such as industrial plants and warehouses that need to carry heavy equipment or items. It is light in weight. Compared with traditional reinforced concrete floors, it can reduce the overall weight of the building, reduce the bearing requirements of the foundation, and facilitate transportation and installation. The construction period is short. Most of the components are pre-fabricated in the factory and assembled on the spot. It can save time and labor costs. It has high space utilization rate and a relatively thin thickness, which can increase the internal space of the building. It is suitable for commercial buildings, office buildings and other buildings with high space requirements. It has good fire resistance performance and can achieve good fire resistance after special treatment. It has a long fire resistance time. It has good earthquake resistance, good steel structure toughness and distortion ability. It can absorb and disperse energy during earthquakes and reduce building damage. At the same time, there were also some shortcomings. The sound insulation effect was poor, and the sound transmission effect of the steel structure was good, resulting in the sound insulation of the floor slab being inferior to that of the reinforced concrete floor slab. The sound of the upper and lower floors was easy to transmit to each other and affect the environment; The maintenance cost was high, and the steel structure was prone to corrosion, requiring regular anti-corrosion maintenance; The initial investment was high, and the material and processing cost was higher than that of the traditional floor slab materials. However, the long-term comprehensive cost might be reduced due to the short construction period and low maintenance cost. It is suitable for general industrial buildings and civil buildings. It can be used in non-earthquake and earthquake-resistant areas of less than or equal to 8 degrees. The bearing weight is higher than that of ordinary floor boards and trestle boards of industrial buildings and civil buildings. The common ones were the steel-framed light panels, which were made of steel and core panels such as steel frames. The interior contained steel mesh, and the outer surface was covered with alkali-resistant fiber mesh and a protective layer of composite mortar, which could better resist external corrosion. There were also types of steel that were made into different shapes through the casting process and then connected with connecting materials. There were also related products such as FC reinforced fiber cement fiber board. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
attic steel structure floor
Safety and material selection should be taken into account when building the steel floor of the attic. Steel structures were one of the most suitable materials for building lofts. There were two types of steel attic floors: channel steel and I-beam. Channel steel was easy to build, but it would vibrate when people walked. It was suitable for smaller spaces with less load. The bending strength of the I-beam was higher, but the cost was also higher. It was suitable for attics with larger spans. The steel structure attic floor was smooth, neat, and uniform in thickness. It had strong load bearing capacity, fire resistance, and water resistance. It could be used directly or tiled and laid. In addition, the construction of the steel structure floor was simple, took up little space, and had the thick and heavy feeling of the cast-in-place floor. In general, the steel attic floor was a safe, durable, and environmental choice.
Steel structure built on the second floor of the room
The steps to build the second floor of the steel structure indoors were as follows: 1. ** Construction design and preparation ** - In terms of design, the layout of the steel structure had to be determined according to the size of the interior space, the bearing capacity, and other factors. Generally speaking, the steel structure of the main beam of the compartment was mostly made of I-beam and channel steel, and the secondary beam was made of square tube or angle steel. For steel with the same cross-section area, the bending strength of H-shaped steel, I-shaped steel, and U-shaped steel decreased in order. - The construction team must be selected by a team with design and construction qualifications, because the reliability of the steel structure not only depended on the quality of the section steel, but also the bending resistance of the main beam. More importantly, it depended on the reasonable connection method between the steel structure and the wall. 2. ** Foundation Connection Construction ** - A combination of planting steel bars and slotting could be used. The groove should be no less than 10 cm deep and 10 mm wide, and the steel bars should be 15 cm deep into the wall to allow the concrete to bear the full force. The bond material used for planting the steel bars must be corrosion-resistant, anti-aging, and the bond strength must be far greater than the strength of the concrete. The curing speed must be fast, so that the implanted steel bars can bear the external force as soon as possible. 3. ** Steel structure construction ** - One method was to use steel that met the national standards to form a crisscrossed steel mesh. For example, the I-beam was the main beam, and the angle steel was the auxiliary beam, which was connected to the main beam. The division of the I-beam was determined according to the size of the pressure steel plate (floor tile, with different thickness of 0.8mm, 1.0mm, 1.2mm, etc.). During the lapping, the I-beam was allowed to bear half of the steel plate or more than the I-beam, so that the I-beam played a leading role in bearing. After the steel frame was connected, the pressed steel plates were floated and then were connected to the steel frame. The deformed steel grid was woven on the steel frame (according to the construction requirements of the concrete structure, the deformed steel bars with a diameter of 10mm and 12mm could be used, and the special binding wire for steel bar construction could be used to connect them). Finally, the light material was poured (such as ceramsite, and the ratio of cement: sand: ceramsite was 1:2:3). - The other method was to place the pressed steel plate into the I-beam, and then to the auxiliary beam (the auxiliary beam was generally 80mm channel steel; when the steel frame had a large span and the main beam was separated, 120mm I-beam could be used as the auxiliary beam), so that it was level with the steel frame, and the steel grid was placed on the steel frame and steel plate for pouring. The difference between the two steel-concrete structure construction schemes was that the former was suitable for the situation where the total floor height was high enough, while the latter was used due to the height restriction. The height difference between the two was 100mm. 4. ** Follow-up Work ** - Wooden planks were laid on the steel structure, and flame-resistant plasterboard roofs could be hung below to form a partition. If it was a steel-concrete structure, it should be noted that its advantage was that it was soundproof and not easy to be deformed. The attic could be used as a toilet and had a good waterproof effect. The disadvantage was that it was heavier and the wall was more stressed. According to the calculation of this structure, the earthquake resistance coefficient was 8 degrees and the service life was more than 70 years.

Light steel courtyard, first floor
The first floor of the light steel courtyard house was a traditional courtyard building with a Chinese style. It consisted of a courtyard and houses that were surrounded on all sides. The courtyard was usually located in the middle. The design of a one-story light steel courtyard usually included two north-facing bedrooms, one on each side of the Ming Hall, with a separate bathroom. The kitchen and dining room were located on the west side of the courtyard, with a terrace in the middle. The study faced east, and there was a public toilet next to it. On the whole, the light steel courtyard house had white walls and gray tiles. It was a separate house, in line with the aesthetic concept of the China people. Its design was reasonable and it was a simple courtyard. The owner could plant green plants and trees outside the yard according to his own preferences to make the house more lively. The gate was the facade of the light steel courtyard house. Its style could show the owner's bearing. The construction of the light steel courtyard was made of light steel structure, which had the advantages of beauty, earthquake resistance, corrosion resistance, low maintenance cost and long service life. Although there were fewer and fewer people building light steel courtyards, there were still some people who loved this architectural style.
100,000 yuan light steel villa, first floor
There were light steel villas on the market that cost 100,000 yuan per floor. In terms of area, there were 100 square meters, 100,000 yuan light steel villas (200 square meters) with supply information; there were also 120 square meters of light steel villas with a cost of 100,000 - 150,000 yuan (150,000 yuan was considered more cost-effective). The cost is affected by many factors. For the steel structure part, the steel consumption of a 300 square meter house is about 30 - 40 kg/square meter. According to this ratio, the steel consumption of 100 - 120 square meters corresponds to about 3 - 4.8 tons. The cost of the light steel structure part can be covered by the processing fee of about 10,000 yuan per ton. Wall (enclosure) and roof construction costs, modeling, appearance materials (For example, the exterior wall can choose different materials such as paint and hanging boards. There are many choices for roof tiles and the prices vary in different regions. The total price of thermal insulation and waterproof materials will also be affected due to the difference in north and south. The filling materials of the interior wall will also affect the overall price. Under normal circumstances, the average price of environmental protection well-known brand materials is less than 800 yuan per square meter. There were also the cost of floor heating (if laying was chosen), the cost of solar roof (if installation was chosen), and the cost of interior decoration (the demand varied greatly, and it was possible to be hundreds to tens of thousands per square meter).
The balanced structure of steel
The equilibrium structure of steel refers to the internal composition of steel in an equilibrium state. A steel with a certain composition has a certain internal composition at a certain temperature, which is called the equilibrium structure of the steel at that temperature. The equilibrium structure can be represented by the iron-carbon alloy phase diagram. The iron-carbon alloy phase diagram was an important tool for studying the structure of iron-carbon alloys with different components at different temperatures. The phase diagram of iron-carbon alloy was a diagram of the relationship between the composition, temperature, and composition of the iron-carbon alloy measured by thermal analysis when the steel changed from high-temperature liquid to low-temperature solid under very slow cooling conditions. The points on the horizontal coordinate of the map corresponded to the iron-carbon alloy with different composition contents; the ordinate corresponded to different temperatures; the letters and symbols marked in each area represented the internal composition of the iron-carbon alloy under certain conditions. The iron-carbon alloy phase diagram was composed of characteristic points, characteristic lines, and characteristic regions. Each characteristic area of the iron-carbon alloy phase diagram indicated the composition of the iron-carbon alloy with different components at different temperatures.(The composition of the iron-carbon alloy with a certain composition at a certain temperature in the horizontal coordinate of the phase diagram would be the composition indicated in the region where the vertical line of a certain composition point on the horizontal coordinate intersected with the horizontal line of a certain temperature point on the ordinate.) The composition of iron-carbon alloy was L (liquid phase),<anno data-annotation-id ="00000000 - 4000 - 4000 - 8000 - 8000 - 80000000000"></anno>(high-temperature Ferrite),</anno>(Ferrite),</anno>(Ferrite),<anno data-annotation-id ="0000000 - 4000 - 4000 - 8000 - 800000000000"> A (Austenite),</anno>,</anno>,</ The equilibrium structure of different types of steel after cooling to room temperature was different. For example, the equilibrium structure of eutectoid steel after cooling to room temperature was pearlite, and the equilibrium structure of hypeutectoid steel after cooling to room temperature was pearlite and secondary crystallizer.

Steel structure model list
The following are some of the commonly used steel models for steel structures: 1. ** H-type steel **: - ** HH **: The height of H-shaped steel is basically the same as the width of the wing. It is mainly used for steel-core columns (stiff steel columns) in reinforced concrete frame structures. It is also mainly used for columns in steel structures. - **Hm**: The ratio of the height of H-shaped steel to the width of the wing is roughly 1.33 - 1.75. It is mainly used as a steel frame column in steel structures. It can be used as a frame beam in frame structures that bear dynamic loads, such as equipment platforms. - **HN**: The ratio of the height of H-shaped steel to the width of the wing is greater than or equal to 2. It is mainly used for beams. The use of I-shaped steel is equivalent to HN steel. 2. ** I-beam **: There are ordinary I-beams (No. 10 - 63) and light I-beams (No. 8 - 70). 3. ** Channel steel **: Including ordinary channel steel (No. 5 - 40) and light channel steel (No. 5 - 40). 4. ** Equal angle steel **: 2 - 20. 5. [Unequal Corner Steel: There are many types.] In addition, carbon structural steel (such as Q195, Q215, Q235, Q255, Q275, etc.), low-alloy high-strength structural steel, high-quality carbon structural steel, alloy structural steel, special-purpose steel, and other grades of steel were used for steel structures.

How to install steel structure factory windows
"In a steel structure factory, the installation of windows is usually a later step in the construction of the entire factory. It is carried out after the installation of the roof panels, wall panels, and other protective structures. The following was the general process: 1. Assembly preparation: - The staff of the organization shall learn and train relevant installation engineering drawings and construction techniques, protect the buildings on site according to the construction plan and layout design drawings, set up obvious signs for the aerial cables within the scope of work, and complete the three supplies and one leveling work on site. - Clean up the lime soil on the column foundation, and remove the accumulated water on the construction site when it rains. - According to the relevant information of the civil engineering team, the horizontal elevation, central line, and interval of the foundation shall be re-measured. Only after the standards are met can the next process be carried out. The cross line of the vertical and horizontal central lines shall be marked on the surface of the foundation as the positioning standard for the installation of the columns. - The components shall be supplied in units according to the installation order. During transportation, the vehicles shall be selected according to the length and weight. The components shall be padded on the vehicles. The longer components shall be marked and bound firmly to ensure that the components will not be deformed or damage the coating during transportation. During the loading, unloading and lifting work, a cushion block must be added between the steel wire rope and the components for protection. Then, the components shall be stacked to the designated position according to the site layout design. The place where the components are stored must be flat and solid without water accumulation. The bottom layer of the components must be padded with wooden pillows without oil stains. The support points of the steel components of each layer must be on the same bisecting line to prevent the steel components from being crushed and deformed. After stacking, an obvious sign must be set up to indicate the model, specifications and quantity of the components for installation. 2. Pillar installation: - Before installation, check the quality of the components. If there is any distortion or defect deviation, it can only be installed after treatment. Before lifting, remove the oil stains, sand, dust and other sundries on the surface. In order to eliminate the influence of the manufacturing deviation of the column length on the column elevation, corresponding measures should be taken. 3. Follow-up structure installation: - The installation of tie bars, hangar beams, purlins, bracing bars, horizontal bracing, gutters/drainage ditches and other structural components, which provide support for the stability of the overall structure of the plant and are also the structural basis for the installation of windows. 4. Exterior protection structure installation: - After completing the installation of the roof and wall panels, he began to install the windows. During the installation, the exact location and size of the window should be determined according to the design requirements. The window should be installed in the reserved window position, and the installation should be firm and well sealed, which should be coordinated with the overall structure and appearance of the factory. 5. Completion acceptance: - Finally, the entire steel structure factory building project, including the installation of windows, was completed and accepted. According to the design drawings and construction plan, the construction was checked to ensure that it met the design requirements and ensured the safety of the steel structure factory building.
