The frame is connected with the building by 3 or 4 struts. The connection point between the struts and the building should be selected on the concrete column or concrete ring beam. The embedded part is combined with concrete, and the embedded part or the wall bolt is connected with the building structure

It is very dangerous to use expansion bolts instead of embedded parts, or use cable and wind rope instead of attachment support, because the attachment device and its accessories are the same products produced by the manufacturer as the standard section. The use of substitutes reduces the strength and stability of the attachment device.
