21、 Part 3: Making and curing test specimens 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 rock anchor anchoring device intended for repeated use after installation, that is inserted into a drilled hole in the rock and held in place b

22、y gluing, or expansion forces, or positive locking, and with an attachment point for a connector (in accordance with 3.1 of EN 12275:1998) 3.2 body of the rock anchor part of the rock anchor that will be installed in the rock 3.3 hanger attachment point capable of being separated from the body of a

23、rock anchor 3.4 installed length distance from the rock surface to the furthest point of the body in mechanical contact with the rock or bonded to the rock, after installation 4 Safety requirements 4.1 Materials All parts of a rock anchor shall be manufactured from the same material. NOTE Depending

24、on environmental factors, rock anchors are potentially liable to suffer from corrosion. Information on the choice of materials and the need for inspection and maintenance is given in Annex B. 4.2 Design 4.2.1 The overall thickness of the border of the eye shall be 3 mm. If the edges are bevelled, th

25、e remaining inner surface shall have a minimum width of 2 mm. EN 959:2007 (E) 6 4.2.2 All corners that will be more than 12 mm from the rock surface shall be rounded to a radius R of a minimum 10 mm (see Figure 1). Dimensions in millimetres Key R minimum 10 mm NOTE A-A see Figure 2 Figure 1 Clear wi

26、dth and external shape of the eye 4.2.3 All edges that can be handled after placement of the rock anchor in the rock shall be rounded to a radius R of minimum 0,2 mm or bevelled to a minimum of 0,2 mm 45 (see Figure 2). This applies to inner and outer edges. Key l1minimum 0,2 mm 45 l2minimum 2 mm l3

27、minimum 3 mm Figure 2 Internal edges of the eye 4.2.4 After inserting the rock anchor in the concrete block, the eye shall be wide enough to accommodate two pins, one with a diameter of (15 0,1) mm for the lower part and one with a diameter of (11 0,1) mm for the upper part (see Figure 1). 4.2.5 In

28、case of expansion-type rock anchors the expansion shall not be dependent on contact with the bot-tom of the drilled hole. EN 959:2007 (E) 7 4.2.6 For glued-in rock anchors, the installed length shall be 70 mm minimum. For mechanical rock anchors, the installed length shall be at least five times the

29、 diameter of the drilled hole (in accordance with the manufacturers instructions). NOTE For installation in rock softer rather than the concrete test block, a longer length can be necessary to achieve the required load bearing capacity. Further information is given in Annex C. 4.3 Loadbearing capaci

30、ty 4.3.1 Axial loadbearing capacity When tested in accordance with 5.3.2.2, the rock anchor shall withstand an axial load of 15 kN, without being pulled out of the concrete block or breaking. Permanent deformation is permissible. 4.3.2 Radial loadbearing capacity When tested in accordance with 5.3.2

31、.3, the rock anchor shall withstand a radial load of 25 kN, without being pulled out of the concrete block or breaking. Permanent deformation is permissible. 5 Test methods 5.1 Check of materials The manufacturer shall confirm that the requirements of 4.1 are met. 5.2 Apparatus 5.2.1 Tensile testing

32、 machine 5.2.2 Concrete block with minimum dimensions of 200 mm 200 mm 200 mm and a compressive strength of (50 10) N/mm2. The maximum grain size of the aggregate shall not exceed 16 mm. The compressive strength of the concrete block shall be verified on three test samples produced as specified in I

33、SO 1920-3. NOTE All concrete testing centres produce these types of concrete blocks to order. 5.3 Procedure 5.3.1 Examination of design Ensure by visual examination and check the dimensions that the specifications in accordance with 4.2.1 to 4.2.6 are met. EN 959:2007 (E) 8 5.3.2 Determination of lo

34、ad bearing capacity 5.3.2.1 Install the rock anchor into a concrete block in accordance with the information supplied by the manufacturer. If rock anchor bodies are supplied without hangers, attach a hanger in accordance with the in-formation supplied by the manufacturer. If hangers are supplied wit

35、hout bodies, attach the hanger to a fixed structure in accordance with the information supplied by the manufacturer. 5.3.2.2 Attach the concrete block to the tensile testing machine using clamps at a distance a installed length l + 5 % away from the axis of the rock anchor (see Figure 3). Apply an a

36、xial load to the rock anchor using a pin with a diameter of (10 0,1) mm in the eye at a rate of (35 15) mm/min, increasing the load to (8 0,25) kN then reducing the load to less than 0,5 kN. Apply this loading a total of ten times within 10 min. Again apply a load, increasing it until failure or unt

Attach the c

38、on-crete block to the tensile testing machine using a support, and a clamp at a distance a installed length l + 5 % away from the axis of the rock anchor (see Figure 4). Apply a radial load to the rock anchor using a pin with a diameter of (10 0,1) mm in the eye at a rate of (35 15) mm/min, increasi

39、ng the load to (8 0,25) kN then reducing the load to less than 0,5 kN. Apply this loading a total of ten times within 10 min.
