EP0959180B1 - Anchorage device - Google Patents

Abstract

The anchoring section (3a) is dovetail-shaped or T-shaped and the basic section (3b) is staged on one side and inclined. The contour of the anchoring device is such that the anchoring section and the basic section so fit together that a virtually pure plate slab section can be realised. The basic section in one of its corner areas has a metallic edge profile (1) for welding.

Description

The invention relates to an anchoring device for anchoring components in concrete, especially in a roadway, with a substantially plate-shaped Anchoring element.

Anchoring devices of this type are known from the prior art and are used in particular in bridge construction, for example around steel edge profiles an expansion joint to fasten, the anchoring device is poured and the profile of the expansion joint up to the road surface enough.

For anchoring expansion joint bridging structures in the concrete of the Bridge superstructure and bridge abutment have been used in recent decades Anchors are used in heavily used carriageway areas in different countries, that of a sheet metal plate and one welded to this sheet metal plate Round steel brackets exist. So it is known from DE 4 425 037 for attachment the anchoring device below the edge profile of an expansion joint to arrange the pavement. The expansion joint extends from an edge profile over joint elements and middle profiles to a second edge profile. The Edge profiles are welded to a plate of the anchoring unit, the plate again with a bracket, with a large number transversely to the direction of the road plates provided with brackets are provided. This anchoring device is complex to manufacture and has an insufficiently adapted to the power flow Cross-sectional dimensions. Furthermore arise from the lateral arrangement of the round steel bracket to the plate unfavorable, problematic Welds and there are bending moments across the anchoring device on. EP 0 826 848 A shows an anchoring device according to the preamble of claim 1 of the present invention.

It is therefore the object of the present invention to provide an anchoring device to create a more efficient and safe manufacture, an improved load transfer in the concrete, a better flow of force in the anchor of the device and enables easy installation of concrete reinforcement bars.

This goal is achieved by an anchoring device with the features of Claim 1 reached. The invention provides an anchoring device for Anchoring components in concrete, which is designed as a sheet metal blank, wherein a first sheet metal disc area (base section) for the steel construction Connection of the component to be anchored is formed and more of the branching first sheet metal disc area, preferably dovetail or T-shaped sheet metal areas with undercuts (Anchoring sections) for the post-like anchoring in concrete.

The invention has the particular advantage that the actual anchor is rational can be burned out or punched out of sheet metal and by its special shape - improved - compared to previously used anchors Load transfer into the concrete, a better flow of force in the anchor itself and a facilitated mounting of the reinforcing bars. Preferably be the anchoring sections provided with the undercuts for Intervention of concrete reinforcement designed. Another advantage of the invention is to see that the steel construction connection of the anchoring devices to the expansion joint profiles according to the state of the art is retained.

Easy to produce variants are characterized by the fact that the anchoring sections are dovetail-shaped or T-shaped, where preferably the base section is stepped on one side and / or has a bevel.

Further advantageous embodiments of the invention are the other subclaims refer to.

1 shows an anchoring device for fastening the edge profile 1 of an expansion joint 2 3, which is arranged below a road surface 4. The Expansion joint 2 extends from the edge profile over joint elements and middle profiles to a further edge profile, for example in a (not shown here) Bridge. The edge profile 1 is with the anchoring device 3 welded, a plurality of these devices transverse to the direction of the road is provided. The anchoring device 3 is poured with concrete 6, a seal 7 being provided between the road surface 4 and the concrete 6.

Pile-like, dovetail-shaped anchoring sections 3a of the anchoring device 3 branch off from a base section 3b, the upper contour is stepped. Those closer to the joint 2 or the edge profile 1 Anchor areas that are subject to greater stress are corresponding more powerfully trained than the less stressed, further from Edge profile removed anchor areas. Problematic weld seams, as with a sheet steel round steel bracket version are required. Above and below the anchor element are due to the geometry of the anchoring device 3 particularly easy to install concrete reinforcement bars 5 laid in particular in the undercuts H of the anchoring sections Intervene 3a.

Fig. 2 shows the advantageous non-cutting, puzzle-like nesting of the Anchoring devices 3 for the flame cut during manufacture. The Anchoring section 3a and base section 3b each fit into one another that a largely cut-free sheet metal blank can be realized. there is the contour of two anchoring devices by a flame cut manufactured at the same time. With flame cutting machines with several In this way, burners can be produced in an extremely efficient manner Anchoring device 3 take place.

Fig. 3 shows analogous to the embodiment of Fig. 1 T-shaped anchoring sections 3a. As in FIG. 2, the wedge-free nesting of the anchoring devices is 3 recognizable.

4 shows an exemplary embodiment with a beveled base section 3b, which can be used when the concrete reaches the bridge or Road surface is sufficient, i.e. if there is no waterproofing and no asphalt on the Connect expansion joint construction.
