ADTOMALL’S acrow steel prop has got a wide application in the construction industry. Acrow steel prop is a kind of column made of steel materials, which forms a framework through combination to play a supporting role of the foundation. In order to enhance stability and reduce support failure rate, it is our best choice to use thick steel reinforcement. Generally, ADTOMALL’S acrow steel props are inclined joint members, and the most common ones are herringbone pattern and a cross shape. The section form can be Steel pipe, H-beam, Angle steel, etc., which can enhance the stability of the structure.

What are the specific applications in the construction industry?

1. Building construction

The first step in building construction is to lay the foundation. What should we use to support the foundation? The best choice is ADTOMALL’S acrow steel props. High-rise buildings require a stable and solid foundation, and steel material is absolutely capable of creating a solid foundation that can support heavy loads.

2. Subway tunnel support

In the construction of the underground tunnel, support is always needed to support the shape of the soil wall. Otherwise, it will collapse at any time. In subway tunnel construction, ADTOMALL’S acrow steel props are used to support the soil wall, which can make the construction personnel working at ease conditions.

3. Working outside of the building

When working outside of the high rise building, we still need to support or lift. We can also use ADTOMALL’S acrow steel props to do good protection to assure the construction workers and construction not fall from the scaffolding system resulting in accidents.

Matters need to pay attention to when using acrow steel prop structure:

1. The arrangement of strain gauge should be installed before the prestress is applied, and the support should be fully cooled when the initial reading is measured. If the prestress has been applied, it must be noted in the report that the data of the support shaft force reflects the change of force after the prestress of acrow steel prop has been applied.

2. After the mounting bracket is welded on the acrow steel props’ surface, push the strain gauge into the stable and free state without bending and torsion. The mounting frame and strain gauge should be kept parallel with the supporting axis. Attention should be paid to control the frequency of strain gauge properly when tightening the screw. The mounting position of the strain gauge should be selected as far as possible in a position suitable for protection.
