Description

Traffic safety railings
5

The invention relates to a traffic safety railing in a modular system.

System components are cross and standpipes, connecting parts and cover caps for

the standpipes.

The field of application concerns the securing of traffic routes, the separation of carriageways or different types of traffic, as well as the use as construction site barriers, fencing, lawn protection railings or generally as railings.

This means that a highly flexible modular system is available for the described application area.

In principle, systems are known that essentially consist of supports and trusses. One design is described in the German utility model G 94 10 107.8.

In addition to other features, adapters, i.e. clamps, are used to connect the supports to the transverse traverses. These allow the traverses to be attached to the supports at different heights. Multiple arrangements are possible. Due to the design of the adapters, several traverses can also be attached to one adapter. This also makes it possible to overcome inclines.

A disadvantage is that the ends of the trusses must have special designs for hanging in the adapters. This means that the distances between the supports must be maintained as precisely as possible.

Furthermore, depending on the shut-off task, a large number of different adapters are required. The manufacturing effort for the adapters appears to be high.

The aim of the invention described below is therefore to eliminate the disadvantages described and to provide a traffic safety railing that is easy to handle, requires as few components as possible, places low demands on the positioning of the standpipes, is highly flexible and reusable and is suitable for series production.

The object of the invention is to construct a traffic safety railing as a modular system that meets the requirements mentioned. Particular attention must be paid to the design of the connecting elements between the upright and cross tubes.

The stated problem has been solved according to the features of claim 1. Expedient embodiments are specified in the subclaims.

According to Figure 5, the traffic safety railing consists, as already mentioned, of upright and cross pipes, which are advantageously round, but can also have other cross-sectional shapes. The upright pipes are closed with a cover cap if necessary. They carry the cross pipes, which can be attached at different heights. A connecting clamp is provided to connect the upright and cross pipes, the structure of which is described below. The latter j§tjGI

For further explanation, drawings are used which show the following: Figure 1 Connecting clamp in front view,

Figure 2 Connection point in plan view,

Figure 3 Connecting clamp in side view,

Figure 4 Combination of standpipe with two cross pipes using two

Connecting clamps,

Figure 5 Possible design of a traffic safety railing.

The reference symbols indicated in the drawings have the following meaning:

1 clamp half,
2 clamp halves,

3 standpipe holder,

4 cross tube holder,

5 standpipe,

6 cross tube,

7 hook connection,

8 joint,

9 screw connection,
10 Cover cap.

As can be seen from Figure 3, the connecting clamp consists of two clamp halves and 2. These are preferably cast parts made of aluminum.

Two mounts are also provided. When the connecting clamp is assembled, these have the shape of a hole or correspond to the outer contour of the standpipe or cross pipe.

The standpipe holder 3 is, as already apparent from the designation, intended for fastening the connecting clamp to the standpipe 5 and is therefore designed to be continuous, while the cross pipe holder 4 is designed as a blind hole.

In the assembled state, the cross tube 6 is inserted into the cross tube holder 4 and is held by pressing the clamp halves 1 and 2 together by means of only one connection, preferably a screw connection 8 (Figure 4). Fasteners made of stainless steel should preferably be used.

Special design of the cross pipe ends is not necessary.

This design allows deviations in the standpipe spacing within certain tolerances.

The center lines of standpipe holder 3 and cross pipe holder 4 lie in different planes and are preferably arranged at an angle of 90° to each other.

Furthermore, the standpipe holder 3 is located outside the center line of the cross pipe holder 4. This has the advantage that when using two connecting clamps on a standpipe 5, as shown in Figure 4, the alignment of the cross pipes 6 is not significantly interrupted by protruding parts of a connecting clamp.

In the area of the standpipe holder 3, a hook connection 7, realized by correspondingly form-fitting clamp halves 1 and 2, provides additional hold (Figure 2).
Optionally, a joint 9 can be provided in the area of the screw connection 8, whereby the standpipe on the holder 3 and the cross pipe on the holder 4 can be pivoted against each other (Figure 1; Figure 4). This makes it easy to set up the traffic safety railing on slopes.

Claims (6)
