Construction of a portal frame metal working system:
Steel structure workshops are divided into simple steel workshops and heavy metal workshops. The workshop structure is mainly made up of steel columns, air columns, roof columns, steel beams, crane beams, inter-column bracing, horizontal roof bracing, wall band, purlin roof, tie bar, and more. parts. The main structure is a portal metal frame, which can be single span, multi-span, or multi-story, with an economic length of approximately 24-30m.
Regular independent notes of portal
Some of the portable metal frame notes include column foot, beam, beam area column, roof roof node, column and roof bracing, tile connecting node, and garbage brackets.
Structure of the steel frame
According to the structure of the steel frame, with the increase in the number of layers and the height and carrying the maximum direct load, side resistance (wind load, earthquake action, etc.) the requirements become the main components of the frame load.
The structure of a steel frame structure is usually divided into frame structure, frame structure, shear frame wall structure, and frame tube structure.
Frame structure: A frame is made up of columns and beams, carrying direct and indirect strength. Steel columns usually use H-shaped steel, box-shaped steel columns, or concrete tube columns.
Frame binding structure: The frame is made up of columns and beams, and bracing is provided between the columns to withstand side forces.
Frame wall shear structure: similar to frame structure, except that bracing is replaced by shear wall to withstand lateral forces.
The shear wall is usually a concrete slab or steel plate, or a composite-concrete structure with better lateral strength than reinforcement and is flexible in design, suitable for high-rise building structures.
Frame tube structure: A structure is usually composed of a reinforced concrete core tube and a steel ring with an outer ring.
The formwork uses pure steel frames in horizontal alignment and arranges the appropriate number of columns between columns in the longitudinal alignment to strengthen the longitudinal stiffness, reduce the amount of metal used in the frame, and create greater space.
Typical nodes for metal frame structure
Common node structures of a steel frame include column foot code, line to column code, column assembly code, column assembly code, assembly code, beam-on-column code, etc.
Construction of steel truss structure
A truss is a structure made up of a number of ornate sticks attached to the ends of each rod and divided into aircraft truss and space truss. The component parts include tube truss, H-shaped steel truss, box-shaped truss, angle steel truss, etc. The truss is usually composed of upper chords, lower chords, straight sticks, web rob, and bracing between the truss. The amount of metal used for the truss is smaller than that of the H beam, the structure is lightweight, and the durability is great. It is widely used in high-rise buildings, high-rise buildings, and bridges.
Structure of the Steel grid structure
A grid is a local structure constructed by connecting multiple nodes with a specific grid. There are many types of grids, divided into different levels. The different design methods are divided into cross-truss system grids, triangular cone system grids, quadrangular cone system grids, and hexagonal cone system grids. A flat grid is made up mainly of chords, diagonal webs, intermediate nodes, support nodes, etc.
