Hairpin of tija filetata 15/17mm - 1,5m

The shuttering system consists of the panel board elements and fasteners presented including by screw coupling hairpins, each of which is completed with couple of coupling nuts with the standard outer diameters of 70 mm.
Diameter of a hairpin 17/15mm. This connection allows to record any type of a timbering precisely (inventory panel board columns, diaphragms and crossbars.

The coupling hairpin is a universal element, possible to application with any type of a timbering thanks to the standardized diameter, including with the D&W system (the plywood laminated with a wooden bar).
The steel hairpin as a rule from brand 45 steel is made (those mozhnot to weld steel with the low content of carbohydrate). Complete with a lambskin nut with a diameter of 70 mm the similar coupling system gives the following competitive advantages:

the carving hairpin without deformation maintains loading depending on concrete type of the screw ranging from 85 to 120 KN;

durability of constructive elements of system conforms to requirements of the DIN 18216 standard;

the full carving on all body of a coupler prevents uncontrollable and spontaneous shift;

! ! ! ! Complete with other fasteners (angular clips, slips and other) coupling shpilkapozvolyat by means of the elementary tools quickly to form a timbering of any complexity. Various fixture and clamps provide a reliable adjunction of boards of a timbering under filling of monolithic reinforced concrete both perpendicularly, and at an angle.
