Application of the whole steel structure in the metallurgical mine project (Part 2)

2 Application of the whole steel structure in the metallurgical mine project

2.1 Engineering example

This project is a dry -election project for the company’s iron ore. The project mainly includes two factory buildings, two independent storage warehouses, transport stations, and twelve tape machinery corridors. The factory buildings are dry elections and rollers, and the storage warehouses include cylindrical warehouses and crude ore warehouses. Before the construction site, it belonged to the hillside wasteland. The landform was eroded by the hills. After the site was excavated, the local venue was relatively flat. Because of the influence of the terrain and landforms, some of the buildings constructed are located on the edge of the slope. In this case, the impact of the weight of the plant and the vibration of the equipment on the slope will be severely increased. The construction of engineering construction is very unfavorable, so the effect of the steel structure is far more than the application effect of concrete. In addition, the owner also hopes to use a significant advantage to complete the construction of engineering projects. The second project is mainly Australia Karara Magnet Mining Project. The construction of this project is mainly due to the remote construction venues and scarce people around them, increasing the cost of transportation and labor costs, which causes the concrete structure to be affected by high cost. To maximize, the use of steel structure is a very effective construction plan.

2.2 Dry Selection Room

The length and width ratio of the dry election interview are 50m: 17m, the maximum position of the highest position is 29.21m, the pillar spacing is 5m, and the span between the left and right spans is inconsistent, which is 9m and 7m, respectively. There are a total of 5 stem machines, 5 corresponding mineral warehouses, 5 to ore belts and 1 mineral warehouse in the plant. The axis AB span requires a crane that can complete the maintenance work. 1 can be completed. The entire structure is mainly framework. Among them, the steel structure selected by the beam pillars is hot-rolled H -shaped steel. The main reason for achieving a good support effect is to choose a round steel pipe. The overall welding materials of the ore warehouse are steel plates, which are made of welding of multiple steel plates with different sizes. The roof is selected from the pressure steel plate, which is open around. The pressure steel plate mainly uses the coating plate or coating plate through the roller, and directly follows the width of the plate to form a wave -shaped cross -shape. The pressure -type steel house has the characteristics of light weight, convenient construction, durability and decorative characteristics, so it is usually used on the panel of the house, which can also effectively increase the side and vertical strength of the floor. The effect of completing the air cavity was completed, and its application value is very high. The calculation of the overall architectural structure is completed in the PKPM space model. The mineral warehouse usually uses independent compilation procedures to carry out construction operations. It is reflected in the beam component and combined with the overall combination to complete the calculation and analysis of the overall data.

2.3 Rolling room

The length between rollers is 34.5m, the width is 6m, the height of the highest position is 29.95m, the distance between columns is 6m, and the span is 13.5m. A high-pressure roller mill, a weighing bin and a feeding belt machine are set up in the workshop, and a crane that can complete the maintenance work is also set up. The crane weighs 75t. The whole structure form is not the same as the structure between dry separation, which is mainly arranged, in which the steel structure selected by the lower column is lattice structure, the steel structure selected by the upper column is solid belly type, the lattice column decorations are mainly T-shaped steel structure, and the rest belong to the welded section, the steel structure selected by the platform beam is mainly hot rolled H-section steel, in order to achieve good support effect, The type of supporting steel structure needs to choose channel steel and round steel pipe. Channel steel can be divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary channel steel are 5-40#. Channel steel can not only be used in building structure, but also play a vital role in vehicle manufacturing and other industrial structures. Under normal circumstances, channel steel is also used in combination with I-steel. According to the specific shape of channel steel can be roughly divided into four kinds: cold curved equal channel steel, cold curved unequal channel steel, cold curved inner wound channel steel, cold curved outer wound channel steel. From the theoretical analysis of steel structure, it can be seen that the stress of channel steel wing plate needs channel steel standing, not lying. The planking of the platform is mainly patterned steel plate; The roof is the same as the dry selection room with many advantages of the pressed steel plate, open all around. When calculating the specific value, PKPM space model is also used to complete the specific construction.
