Industrial buildings adopt appropriate structural forms according to building density, application effect, seismic grade characteristics and surface hydrological survey report. The network braiding and belt making team master the ten knowledge points of “structural form” of steel structure.

Q1. Classification and characteristics of general structure management system?

The common structure management system includes brick concrete structure, frame column, frame frame column, tube section, truss structure, spherical grid, arch, suspension bridge, thick wall indoor space, etc. the key points of steel structure include portal steel frame, frame, truss structure and spherical grid structure. The advantages and disadvantages of different construction management systems are different, and the bearing mode is also different. The actual engineering constructionThere are usually two kinds of structures in architecture.

Q2. General steel structure form characteristics and application cases?

Portal steel frame is widely used in industrial production, commercial services, cultural and art public facilities and other industrial production and industrial buildings.

The steel frame layout plan is convenient and can produce large indoor space. It is widely used in double-layer, high-rise residential and high-rise buildings, commercial service office buildings, International Conference Center and other engineering buildings.

The advantage of steel pipe truss is that it can use small cross-section components to form prefabricated components with large cross-section. It is commonly used in industrial production and industrial buildings, such as roof truss, highway bridge, radio and television tower, bow tower, service platform of deep-sea oil production plant, six storey outdoor stairs, etc.

Spherical grid structure is a high-order statically indeterminate spatial layout composed of many components according to certain regularity. It has small bearing capacity, light weight, large bending stiffness and good durability. It can be used as roof truss of stadium, exhibition hall, waiting hall, canopy, hangar and other engineering buildings.

Q3. Structure system software composition of portal steel frame industrial workshop?

The steel structure industrial workshop is divided into light steel plant and heavy steel industrial plant. The key of industrial plant structure system software is composed of steel beam, wind column, ring beam column, flat roof steel column, crane beam, column support, horizontal support of steel roof truss, wall steel purlin, steel purlin, full view window frame, tie bar, etc.The behavior subject of portal steel frame is portal structure, which can be single span, multi span, or double-layer. The span of economic development is about 24-30m.

Q4. What are the common connection points of portal steel frame industrial plants?

The common connection points of portal steel frame include column base connection point, column beam connection point, steel roof truss beam connection point, column support connection point, tie bar connection point, drainage ditch fixed support connection point, etc.

Q5. Software composition of steel frame structure system?

For steel structures, with the increase of the number of superimposed layers and height width ratio, in addition to bearing a large longitudinal load, lateral force (wind load, earthquake disaster effect, etc.) regulations become the key bearing characteristics of the structure. Its infrastructure management system is generally divided into three types: column formwork support system, pure framework management system, and framework template support system.Among them, the framework formwork support system is widely used in specific engineering projects. This kind of management system adopts the pure steel structure horizontally, and the vertical layout is moderate, and the total number of longitudinal column supports is used to enhance the vertical bending stiffness, so as to reduce the steel content of the framework and produce a large indoor space.

Q6. What are the common connection points of steel frames?

The common connection points of steel frame structure include column base connection point, column connection point, column beam connection point, beam beam connection point, support point connection point, main beam column connection point, etc.

Q7, steel pipe truss structure system software composition?

Truss structure is a structure composed of several members connected by hinges on both sides of each pole, which can be divided into plane truss structure and indoor space truss structure.It can be divided into pipe truss, H-section steel truss structure, box cross-section truss structure, angle steel pipe truss, etc.Truss structure is generally composed of upper link, lower chord, vertical bar, diagonal web member, support point between truss structures, etc.Truss structure is widely used in multi-storey building, long-span structure and highway bridge because of its large volume of steel, less solid web beam, light structure and large bending stiffness. 

Q8. What are the common connection points of steel pipe truss? 

The common connection points of steel pipe truss are the connection points of vertical bar and upper and lower chord, the connection point of inclined web member and upper and lower chord, and the connection point of truss structure. 

Q9. Software structure of spherical grid structure system?

Spherical grid is a spatial layout composed of several components connected with each other according to a certain grid diagram.There are many types of spherical space grids, which can be classified according to different specifications. According to the different composition methods, China usually divides them into the cross truss structure management system spherical grid, triangular cone management system spherical grid, quadrangular cone system spherical grid, hexagonal cone system spherical grid.The key of the spherical grid structure of tablet computer is composed of chord, diagonal web member, middle connection point and rubber bearing connection point.

Q10. What are the common connection points of spherical grids?

The key points of spherical grid structure are vane connection point, welding hollow ball connection point, bolt ball connection point and rubber bearing connection point.The cross plate connection point is suitable for the steel structure grid structure of channel steel components. The connection between the components and the connection point plate is made by welding or high-strength bolts.Hollow ball connection point and bolt ball connection point are suitable for steel structure grid of seamless steel pipe members.
