適用范圍：This British Standard specifies requirements for adjustable compression tubular steel trench struts. The requirements relate to materials, design, dimensions, strength and resistance to unintentional disengagement. The dimensions specified include the lengths fully open and fully closed. The standard does not give information on the use of trench struts. NOTE 1 The requirements of this standard are intended to ensure that the struts will have a characteristic resistance of 50 kN at all extensions. The standard does not specify a requirement for this characteristic resistance or a means of verifying it. Annex A gives examples of calculations on trench strut pin connections. NOTE 2 Various protective finishes are specified in BS EN 1065:1999.
