Construction Plan for Composite Steel Platform

Description :

　　Characteristics of Steel Platform Structure

　　1. The steel platform produced by the shelving factory is assembled as a whole without the need for on-site welding. It is usually composed of beams, columns, plates, and other components made of steel sections and plates, and connected by screws or rivets between each part. This steel platform has fast construction, moderate cost, easy installation and disassembly, and can be reused in a new location. Its structure is novel and beautiful.

　　2. The structure of steel platform shelves mainly consists of main beams, columns, floor slabs, railings, and stairs; The overall structure adopts a modular design, without the need for on-site welding. The floor bearing capacity of a typical steel platform can reach 200kg~1000kg/square meter.

　　3. The supporting columns of the steel platform are made of pipes with strong bearing capacity and low steel consumption. The main beam is made of H-beam or I-beam, and the secondary beam is made of buckle crossbeam produced by Korisen Storage Shelf Factory. This type of crossbeam has the advantages of strong bearing capacity, light structure, and low cost.

　　4. The floor planks are made of cold-formed patterned steel plates or hollow boards produced by Korisen Storage Shelf Factory. The planks are connected by a buckle plate structure, which is rigidly fixed to the main and secondary beams. The overall structure of the platform is strong, and different floor panels can be selected according to the actual use of the customer to meet the requirements of fire protection, dust prevention, and small item falling prevention.

　　5. The steel platform can be equipped with elevators and lifting platforms for easy loading and unloading of goods. Goods are transported to the second and third floors by forklifts or lifting platforms, and then transported to the designated location by small cars or pallet trucks. Warehouse management personnel operate it easily, quickly, and efficiently.

　　6. All materials are carbon structural steel, and the surface is treated with shot blasting, phosphating, and spray coating for corrosion resistance. It has superior load-bearing performance, simple and elegant appearance, and can meet the storage needs of various industries and large items or whole pallets of goods.

　　The process of building the attic platform

　　Construction process:

　　Construction site investigation - raw material procurement, inspection, and entry into the construction site - rust removal - cutting - re inspection of embedded parts - steel column hoisting - inspection and correction - welding - steel beam hoisting - inspection and correction - welding - support system installation - inspection and correction - welding - spraying anti rust paint - preliminary inspection of the main body - acceptance of Suzhou attic steel structure steel platform and steel structure staircase construction

　　The strength, stability, and deflection of steel platform beams should be calculated. The fatigue strength calculation should also be carried out for beams that directly bear large vibration loads. The design of steel platform beams generally does not consider the development of plastic deformation; When necessary, calculate according to the requirements and formulas listed in the Steel Structure Design Code (GB50017-2003).

　　The simple connection method between the secondary beam and the main beam is stacking. Put the secondary beam directly onto the main beam and connect it with welds or bolts. The required building clearance for stacking is large, and the use of this method is often limited. Therefore, the equal height connection between the secondary beam and the main beam is a commonly used method. There are two construction forms for the hinge connection between beams and columns:

　　Setting the beam directly on the top of the column makes the connection structure relatively simple. The total reaction force of the beam support is transmitted to the column stiffeners through the connection weld between the top plate and the column stiffeners or through the end face of the beam stiffeners under pressure. The force is then transmitted to the column web through the vertical connection weld between the column stiffeners and the column web.

　　Design of Steel Platform Structure Deck

　　Steel platform planks can be divided into fixed and detachable according to the production process requirements; According to the structure, it can generally be divided into plate type, grate type, and joint structure composed of steel beams and concrete slabs.

　　Advantages of attic steel structure

　　The architectural style is flexible and rich. Large open room design, indoor space can be divided into multiple schemes to meet the different needs of users, and the area utilization rate can be improved by reducing the cross-sectional area of columns and using lightweight wall panels,

　　Good energy-saving effect, the wall adopts lightweight energy-saving standardized prefabricated wall panels instead of clay bricks, with good insulation performance and energy saving of --%,

　　The use of steel structure systems in residential buildings can fully utilize the good ductility, strong plastic deformation capacity, and excellent seismic and wind resistance performance of steel structures. The steel reinforced concrete column fully and reasonably utilizes the material properties of steel and concrete, and reduces the section by increasing the corresponding strength. Its compressive and lateral bending strength are higher than that of concrete columns -This greatly increases the ability to resist strong earthquakes and improves the safety and reliability of residential buildings. Especially in the event of earthquakes or typhoons, it can prevent the collapse and damage of buildings.

　　The total weight of the building is light, and the steel structure residential system uses various lightweight materials to form high-strength, fireproof, waterproof, heat-insulating, soundproof, and energy-saving composite walls, replacing traditional clay bricks and other bulky masonry materials.

　　The construction speed is fast, and the steel structure adopts a lightweight building steel structure system, which does not require on-site binding of steel bars or the production of templates. When pouring concrete into the floor slab, there is no need for temporary support, which can greatly accelerate the assembly speed on the construction site. Therefore, the construction period of lightweight building steel structure system can greatly shorten the occupation period of investment funds and improve the efficiency of fund utilization.

　　Good environmental protection effect.
