18、ification CEN/TS 1992-4-5 Post-installed fasteners Chemical systems, describes the principles and requirements for safety, serviceability and durability of post-installed fasteners with chemical anchorage systems for use in concrete. This Technical Specification does not provide information about th

19、e use of National Determined Parameters (NDP). CEN/TS 1992-4-5 is based on the limit state concept used in conjunction with a partial factor method. CEN/TS 1992-4 Design of fastenings for use in concrete is subdivided into the following parts: Part 1: General Part 2: Headed fasteners Part 3: Anchor

20、channels Part 4: Post-installed fasteners Mechanical systems Part 5: Post-installed fasteners Chemical systems Connection to Part 1 of this Technical Specification TS The principles and requirements of Part 5 of this CEN/TS are additional to those in Part 1, all the clauses and subclauses of which a

21、lso apply to Part 5 unless varied in this Part. Additional information is presented under the relevant clauses/sub-clauses of Part 1 of the CEN/TS. The numbers for the clauses/sub-clauses of Part 5 continue from the number of the last relevant clauses/sub-clauses of Part 1. The above principles also

22、 apply to Figures and Tables in Part 5.

30、is of design 4.1 General 4.5.4 The following assumptions in respect to installation have been made in this CEN/TS. The installation instructions should reflect them: 1) Concrete has been compacted adequately in the area of the fastening. This should be checked prior and during installation via visua

31、l check. 2) Requirements for drilling operation and bore hole: Holes are drilled perpendicular to the surface of the concrete unless specifically required otherwise by the manufacturers instructions. Drilling is carried out by method specified by the manufacturer. When hard metal hammer-drill bits a

32、re used, they should comply with ISO or National Standards. When diamond core drilling is permitted, the diameter of the segments should comply with the prescribed diameter. Reinforcement in close proximity to the hole position is not damaged during drilling. In prestressed concrete structures it is

33、 ensured that the distance between the drilling hole and the prestressed reinforcement is at least 50mm; for determination of the position of the prestressed reinforcement in the structure a suitable device e.g. a reinforcement detector is used. Holes are cleaned according to the instructions given

34、in the European Technical Specification. Aborted drill holes are filled with high strength non-shrinkage mortar. 3) Inspection and approval of the correct installation of the fasteners is carried out by appropriately qualified personnel. NOTE Many drill bits exhibit a mark indicating that they are i

35、n accordance with ISO or National Standards. If the drill bits do not bear a conformity mark, evidence of suitability should be provided. 5 Determination of action effects The determination and analysis of the condition of the concrete cracked or non-cracked - serving as base material for the fasten
