Embodiment Construction

[0017] exist figure 1 The expansion bolt 1 shown in has an elongated expansion bolt sleeve 2 with a channel 3 extending along the longitudinal axis. The expansion bolt sleeve 2 has an expansion section 4 at the front end, to which a handle section 5 is connected. "Front end" and "rear end" always refer to the joining direction E of the expansion bolt during installation. The transition from the shank section 5 to the expansion section 4 is characterized in that the channel 3 narrows considerably to approximately half the diameter, while the outer diameter expands essentially only very slightly conically toward the rear. The shank section 4 is again expanded in the outer diameter by approximately 20% in the rear quarter. The expansion section 5 has such a notch 6 that the outer side of the expansion section 5 has a barb-shaped structure. At the rear end of the bolt sleeve 2 the shank section 4 is enlarged to the first flange 7 and a fastening disk 8 is arranged at this poin...

Abstract

The invention relates to a dowel (1) and a setting method for fixing insulating materials (25). The dowel (1) has a bolt (13), a dowel sleeve (2) and a fixing disc (8). In order to realize compact supply and immersion type of dowel, the invention suggests that the fixing disc (8) is axially fixed and rotatablely connected to the dowel sleeve (2), and the dowel sleeve (2) has such a reduction zone (22) in a handle rod segment (4) that the dowel sleeve is shortened by screwing the bolt (13) in a base (26), especially plastically compressible.

Description

technical field [0001] The invention relates to a plug having the features stated in the preamble of claim 1 and an installation method for fastening insulating materials having the features stated in the preamble of claim 6 . Background technique [0002] Document EP 1 318 250 A2 discloses a bolt and an installation method which enable so-called "submerged" fastening of insulating material to a foundation. For this reason this document is in an embodiment ( Figures 1 to 3 ) suggested that a bolt be equipped with a fixed plate, wherein the fixed plate can rotate relative to the bolt sleeve. After inserting the expansion bolt into the pre-drilled hole, first the bolt is turned, and then the bolt and the fixing disc are turned together. The fixing disc cuts into the insulating material by rotating the fixing disc. The bolt continues to be pulled into the retaining disc into the insulation, where it compresses the insulation. The fixed plate is axially displaceable and rota...
