Designation
Double anchor plate SN 225-2 – 48 x 290 – 5.6

Example: designation of a double anchor plate, size 48 and threaded bolt distance k = 290 mm for threaded bolts of property class 5.6.

4

Material

Anchor plate, plate made of S355JR+N according to DIN EN 10025-2. Centering pipe made of E235+N according to DIN EN 10296-1.

5

Execution

Cut out by flame, deburred and welded, with continuous fillet weld according to ISO 2553. Rolling skin, annealing scale and rust shall be removed by blasting. Surfaces without marking shall be left without coating or preservation. Indoor storage is required to avoid new formation of rust.

6

Identification

In case of e.g. thread size M48 and threaded bolt distance k = 290, double anchor plates shall be provided with permanent marking 48 x 290 in the form of welding beads for bolts of property class 5.6. Example of identification:

SN 225 – 2 – 48 x 290 – 5.6

Height of machine base plate. The dimensions of v are based on washer thicknesses as in SN 808 + 1 x nut height as in DIN EN ISO 4032 (DIN 934) + ? 1 x d1 for the application of hydraulic pretensioning units as in NH (SMS Standards Book), Part 5. The length of the shuttering sleeve shall be chosen such that the sleeve projects by 100 mm over the raw concrete and can be subsequently adapted. The dimensions of w are based on rounded values of 20 x d1 without taking into account the quality of the concrete, reinforcement etc. Dimension ü is a variable overmeasure. Dimension L results from v+n+g+w+a+s+m+ü. After alignment/levelling of the anchor plate in the reinforcement, the customer shall arrange for water-tight welding of the shuttering sleeve.
