Each building is composed of each component, and the role of each component is very different. Steel components are composed of many building structures today. The steel structures selected by each part have different functions.
The establishment of the
steel structure plant is composed of several parts. Most of the five parts of steel columns, steel beams, steel roofs, and steel reservoirs, and walls also include parts and steel components in other parts. What is the impact of the common main component of the steel structure plant on the quality of the whole structure?
The accuracy of the manufacturing standard of steel structure plant components is the prerequisite for ensuring the overall quality of the steel structure plant. Therefore, it is necessary to accurately grasp the distance and misunderstanding of the steel column, the distance from the connection holes of the column and the beam to the bottom plate, and the connection hole itself The processing accuracy of the processing accuracy, the straight line of the roof beam, and the processing accuracy of the pillar beam connection board, the tie rod on the beam pillars or the position standard of the beam pillar itself, and the orientation standard of the bracket board.
At present, the pillar in the steel structure plant is compiled by the forefront H steel processing or plate. It is assumed that the ready -made H -shaped steel processing, the accuracy of the pillars is briefly controlled; Plasticine the steel column to ensure that the steel column is straight and avoid misunderstanding.
The roof beam is a bit of human -shaped structure, which is generally assembled from 2 榀 or 4 榀. The roof beam is generally assembled by the manufacturer with plates, and the abdomen of the beam is generally irregular quadrangers. The manufacturer with strong skills can be accurately grasped on the sample of the abdomen. There is no error in the sample standards. Because the shape of the roof beam is related to the tightness of the couplet between the beam and the column, the standard of the abdomen directly affects the shape of the beam, so it is particularly required.
In the structure of the steel structure plant, common main structures include steel columns and steel beams. This is a major part of support and load. The composition of the structure is an important part. Steel columns are divided into real abdominal columns and grid columns. The actual abdomen column has all sections. The commonly used section of the industrial -type, H -shaped section; the cross section of the grid column is divided into two or multi -limbs, and each limb is connected with a strip or plate. When wider, the amount of steel is saved.
Steel beams, stylish steel beams, combined beams. The crane beams and work platform beams, floor beams in multi -story buildings, and bars in the roof structure can be selected. The steel beam is made of hot -rolled steel or slot steel. The type of steel beam is simple and the cost is cheaper, but the standard steel section standard is standardized. When the load and span are large, and the selection of steel cross section cannot meet the strength, stiffness, or stable requirements, the combination beam is selected.
The combined beam is welded or riveted by steel plates or steel steel. Because riveting costs are often welded, the commonly used welded combination beams as H -shaped cross -section and box -shaped section composed of upper, lower winged edges and abdominal plates. However, it has a large bending rigidity and twist -resistant rigidity. It is suitable for high -oriented loads and high twist -resistant requirements, or beams are restrained.
The components of steel structure engineering can choose different data to establish and form. There are also differences in different data functions and quality. Also can also create different types of factories, such as multi -layer steel structure factories, light steel structure buildings, brick -concrete structure plants For types of buildings, only the quality of the relevant components can be controlled to advance the equipment quality of the entire structure.
