Building Steel Support

What are the types of building steel supports?

According to their load-bearing capacity, they can be divided into lightweight steel supports and heavy-duty steel supports. According to their characteristics, they can be divided into: ordinary nut steel support, cup-shaped nut steel support, flat bracket steel support, and U-bracket steel support. The thickness of the pipe wall is 1.8mm, 2.0mm, and 2.2mm.

The main function of building steel support in construction is to strengthen the stability of the structure, so that the purlins are not easily unstable and damaged under certain external forces. Steel supports should be adjusted reasonably according to actual needs during use.

What issues should be noted when using strain gauges for building steel supports?

1. The arrangement of strain gauges should be installed before prestressing is applied, and the initial reading measurement should wait for the support to cool sufficiently; If prestressing has been applied, the report must indicate that the supporting axial force data reflects the change in force of the steel support after prestressing has been applied.

2. After welding the installation bracket onto the steel support surface, push the strain gauge smoothly and freely without bending or twisting; The installation of mounting brackets and strain gauges should be kept parallel to the supporting axis; When tightening screws, attention should be paid to controlling the frequency of strain gauges reasonably; The installation position of strain gauges should be selected as much as possible in a location suitable for protection.

What issues should be noted when connecting steel support heads to crown beams or waist beams?

1. The supporting end should be equipped with a steel plate with a thickness of not less than 10mm as the head end plate. The end plate should be fully welded to the supporting rod, and the thickness and length of the weld seam should be able to withstand all the supporting force or the same strength as the support. If necessary, stiffeners should be added. The number and size of rib plates should meet the requirements of local stability at the supporting end and the transmission of supporting force.

2. When the supporting end face is not perpendicular to the supporting axis, embedded iron components or other structural measures can be installed on the crown beam or waist beam to withstand the shear force between the support and the crown beam or waist beam.

As an important component commonly used in construction, the correct storage method is crucial for ensuring the performance and service life of building steel supports.

Firstly, a dry and well ventilated warehouse or storage area should be selected. Avoid storing building steel supports in damp and water prone areas to prevent rusting and corrosion of the steel. At the same time, it is necessary to ensure that the temperature of the storage environment is relatively stable and avoid damage caused by extreme high or low temperatures.

When storing, the building steel supports should be classified and organized, neatly stacked according to specifications and models. Shelves or pallets can be used to keep the supports at a certain height above the ground to prevent direct contact with the ground and moisture. For supports of different lengths and sizes, they should be stored separately for easy management and retrieval.

To prevent collision and compression deformation of building steel supports during storage, cushioning materials such as wooden boards or rubber pads should be placed between each layer. Meanwhile, it is important to avoid stacking too high to prevent deformation of the bottom support components under pressure.

For building steel supports with adjustable components, the adjustment device should be in a relaxed state to avoid prolonged tension and stress, which may affect its adjustment performance and service life.

In the storage area, clear signs and labels should be set up to indicate the specifications, quantity, production date, and other information of the building steel supports for easy and quick search and inventory.

In addition, regularly inspect the stored building steel supports for rust, deformation, damage, and other conditions. If there are any problems, take timely measures such as rust removal, repair, or replacement.

In short, the correct storage method can effectively protect the quality and performance of building steel supports, providing reliable guarantees for subsequent construction use.
