Embodiment Construction

[0049] according to figure 1 A diamond saw blade 1 is shown, which has a disk-shaped core 2 and has a surrounding section 3 on its outer circumference 2.1. The segment 3 is subdivided into a plurality of segment regions 3.1, 3.2, 3.3 etc. by means of radially extending cutouts 4. FIG. The segments 3 or the segment regions 3.1, 3.2, 3.3 are preferably fastened to the core 2 by sintering, soldering, adhesive bonding or welding. Centrally provided in the core 2 is a concentric hole 5, by means of which the diamond saw blade 1 can be inserted onto the shaft 6 of a sawing tool 7 (see image 3 ).

[0050] According to this embodiment, the segment 3 is formed by six layers 8.i (i=1 to 6), the layers adjoining each other planarly in the axial direction X, as in figure 2 as shown in. In the axial direction X, each layer 8.i has a layer width B1 of approximately 1 mm, so that the segments 3 have in total a segment width B2 of 6 mm. The core width B3 is approximately 3 mm, ie the c...

Abstract

The invention relates to a sawing tool (7) for forming a surface structure on a road surface, at least having: a shaft (6) and a plurality of diamond saw blades (1), wherein each diamond saw blade (1)has a disc-shaped core with a hole for placing on the shaft (6), and a segment (3) which is arranged on an outer circumference of the core, wherein the diamond saw blades (1) are arranged on the shaft (6) by way of the disc-shaped core. The invention provides for the segments (3) of adjacent diamond saw blades (1) to be in surface contact on a longitudinal side (13), wherein each segment (3) is formed from at least two layers (8.i; i=1...6) that adjoin one another in the axial direction and each extend in the radial and axial direction, wherein layers (8.i; i=1...6) of the segment that axially adjoin one another each have different wear resistances (VF, VF1, VF2) and the wear resistance (VF, VF1, VF2) of the layers (8.i; i=1...6) in the axial direction alternates over the entire segment (3), wherein a furrow is able to be formed in each case by two layers (8.i; i=1...6) that axially adjoin one another, in order to set a grip and a level of noise of the road surface, and layers (8.i; i=1..6) that axially adjoin one another of adjacent segments (3) have different wear resistances (VF, VF1, VF2) in order to form an alternating layer structure over the entire sawing tool (7).

Description

technical field [0001] The invention relates to a sawing tool with a plurality of diamond saw blades for forming surface structures, in particular longitudinal grooves, on road surfaces, as well as to a machine with such a sawing tool, and to a tool for making surface structures on road surfaces methods for forming surface structures. Background technique [0002] In the production of roadways for vehicles, after concrete has been applied to the road base, for example, a smooth road surface is produced in several steps, which however is slippery for vehicles to drive safely. To roughen the road surface, sawing tools with diamond saw blades are used which provide the road surface with a structuring or texture, for example longitudinal grooves extending in the direction of travel. The longitudinal grooves ensure, inter alia, improved road resistance for vehicles running on the road. In this context, "slip resistance" is understood to mean the extent to which the driving forc...
