Galvanized Commercial Steel Structural Pipe Truss Roof For Shopping Mall

Pipe truss refers to a lattice structure formed by connecting round rods at the ends. The truss makes the truss structure material economical, and the structure is light in weight, and it is easy to form various shapes to adapt to different purposes, such as simply supported trusses, arches, frames, and towers.

 

Compared with the grid structure, the tubular truss structure saves the lower chord longitudinal members and the spherical joints of the grid frame, which can meet the requirements of various building forms, especially the construction of round arches and arbitrary curved shapes is more advantageous than the grid structure. Its stability in all directions is the same, saving material consumption. The steel pipe truss structure is developed on the basis of the grid structure. Compared with the grid structure, it has its unique advantages and practicability, and the amount of structural steel is also more economical.

 

Performance:

1. Strength:

The strength index of steel is composed of elastic limit σe, yield limit σy, and tensile limit σu. The design is based on the yield strength of steel. High yield strength can reduce the weight of the structure, save steel, and reduce the cost. The tensile strength σu is the maximum stress that the steel can withstand before failure. At this time, the structure loses its performance due to large plastic deformation, but the structure is not deformed and does not collapse, which meets the requirements of the structure to resist the rare earthquake. ‘Σu / σy value can be regarded as the parameter of steel strength reserve.

2. Plasticity:

The plasticity of steel generally refers to the property of having significant plastic deformation without breaking after the stress exceeds the yield point. The main indexes to measure the plastic deformation ability of steel are elongation δ and section shrinkage ψ.

3. Cold bending performance:

The cold bending performance of steel is a measure of the resistance of steel to cracking when plastic deformation occurs at room temperature. The cold bending performance of the steel is to use the cold bending experiment to test the bending deformation performance of the steel under the specified bending degree.

4. Impact toughness:

The impact toughness of steel refers to the ability of steel to absorb mechanical kinetic energy during fracture under the impact load. It is a mechanical property that measures the resistance of steel to impact load. It may cause brittle fracture due to low temperature and stress concentration. The impact toughness index of steel is generally obtained through the impact test of standard test pieces.

5. Welding performance:

Welding performance of steel refers to welding joints with good performance under certain welding process conditions. Welding performance can be divided into welding performance and welding performance in the welding process. Welding performance in the welding process refers to the susceptibility of the welding seam and the metal near the welding seam to no thermal cracks or cooling shrinkage cracks during the welding process. Good welding performance means that under certain welding process conditions, the weld metal and the nearby base metal will not crack. The welding performance in terms of serviceability refers to the impact toughness and ductility of the heat affected zone at the weld seam. China adopts the welding performance test method in the welding process, and also adopts the welding performance test method in the nature of usability.

6. Durability:

There are many factors that affect the durability of steel. The first is the poor corrosion resistance of steel, and protective measures must be taken to prevent steel corrosion and rust. Protective measures include: regular maintenance of steel paints, the use of galvanized steel, and the use of special protective measures in the presence of strong corrosive media such as acids, alkalis, and salts. The zinc ingot is fixed on the jacket, and the seawater electrolyte will automatically corrode the zinc ingot first, so as to achieve the function of protecting the steel jacket. Secondly, due to the high temperature and long-term load, the destruction strength of the steel is lower than that of the short-term strength. Therefore, the long-term high-temperature steel must be tested for long-term strength. The steel will automatically become hard and brittle over time, which is the phenomenon of "aging". The impact toughness of steel under low temperature load shall be tested.

 

Compared with traditional steel trusses with open cross-sections (H-shaped steel and I-shaped steel), the material of the pipe truss structure is more evenly distributed around the neutral axis, so that the cross-section has good compressive and flexural-torsional bearing capacity and greater rigidity. Without gusset plate, the structure is simple. The most important thing is that the tubular truss structure is beautiful in appearance, which is convenient for modeling and has a certain decorative effect. The overall performance of the pipe truss structure is good, the torsional rigidity is large, and the appearance is beautiful. It is easy to manufacture, install, turn over, and lift; the steel pipe roof truss made of cold-formed thin-walled steel has light structure, good rigidity, steel saving, and can give full play to The advantages of material strength, etc., are more economical, especially in the strut and support system controlled by the slenderness ratio. Buildings with this structure are basically public buildings. The structure has the characteristics of beautiful appearance (it can be built into flat shape, round arch shape, arbitrary curve shape), convenient production and installation, good structural stability, high roof rigidity, and good economic effect.
