Improving the management level of the scaffolding leasing industry

At present, there is a large stock of scaffolding in China. According to incomplete statistics, the country has a stock of over 100 million square meters, which cannot be ignored. Currently, management should be strengthened and reasonable distribution should be carried out. Those that can be repaired should be standardized and renovated, such as overall shot blasting, replacement of accessories, fine shaping, and painting,

Analysis of Installation Technology for Steel Supports

1. When installing the steel support, the measuring group sets out the support position, processes the steel purlin outside the site, and welds the support bracket steel pad with the drop out plate on the steel purlin. According to the width of the foundation pit, the group is assembled into a subway steel support with one end fixed and one end movable, and the length is based on the section width

How to pressurize the steel support?

Two 100t hydraulic jacks are used for support erection to apply pressure, symmetrically and step by step along both sides of the support at the moving end. The pre applied axial force for steel support erection is 50% of the planned axial force, applied in three stages. Apply 30% of the planned support axis force,

What should be noted when using strain gauges for steel support?

Student question: What should be noted when using strain gauges for steel supports? [Answer]: 1) The arrangement of the strain gauge should be installed before the prestressing force is applied, and the initial reading should wait for the bracket to fully cool down; If the prestressing force has been applied, the supporting axial force must be indicated in the report

Processing and manufacturing requirements for steel formwork

The operators at each workstation during the steel template processing must process according to the steel template processing process and the material model specifications and size requirements on the construction drawings.

What is a steel template?

Steel formwork can replace wooden formwork, significantly reducing the elimination of pore water pressure and bubbles in concrete pressure that are usually associated with traditional sealing formwork such as wood, plywood, or steel plates; After the steel template structure concrete is poured and formed, an ideal rough interface is formed. No rough cutting operation is required to proceed to the next process of construction.

What are the advantages and disadvantages of steel formwork construction

Advantages of steel formwork: reinforcement system, high component strength, and high combined stiffness; High precision in plate production and tight seams; Not easily deformed, the template has good integrity and strong seismic resistance. Disadvantages of steel formwork: The formwork has a large weight and requires lifting machinery for mobile installation, resulting in high costs

Scope of application of steel support

Simply put, the 16mm thick supporting steel pipes, steel arches, and steel grids used in subway construction are all used for support, blocking the soil walls of culverts and tunnels to prevent foundation pit collapse. They are widely used in subway construction.
