DE3816644C2 - Bollard - Google Patents

Description

The invention relates to a bollard for controlled blocking of traffic surfaces such as roads, driveways or parking lots, with the head closing off ne barrier post consisting of a square tube optionally flush with the road surface runs out of or along an axis perpendicular to the road surface protrudes and preferably hydraulically or mechanically, e.g. B. by counterweights, can be actuated.

Corresponding posts made of metal are CH-PS 644 418 and DE 86 16 261 U1 refer to. The post is hollow, so that at high loads such as For example, an impact of a vehicle is at risk of buckling. This means that the lock function no longer exists. This also applies to an increasing extent for posts made of plastic, even if in them to increase stability an inner tube or be embedded in a plastic anchor strip or stiffening strips extend from the inner surfaces of the post (DE-AS 20 57 623, DE-AS 16 58 660, DE-AS 20 09 933).

Therefore, the last-mentioned posts are only used as guide posts, i.e. for management and not Barrier purposes used. For this reason, there is also a stationary arrangement.  

If a metal post of the type mentioned can be raised or lowered can be adjusted using hydraulic drives, counterweights or chains drives take place (EP 0 177 895 A2, CH-PS 644 418, DE 86 16 261 U1).

The object of the present invention is to provide a bollard of the type mentioned to be trained in such a way that effective constructional protection from locking areas is possible. In particular, the possibility should also be given be to absorb greater forces.

The object is achieved in that the inside of the square tube Wall of the square tube touching round tube that runs from the inner edges of the Square tube to the outer wall of the round tube are radial stiffeners and that existing spaces are shed between the round tube and the square tube are. The free spaces can be poured with concrete. With the stiffeners themselves it is preferably gusset plates.

The teaching according to the invention creates the possibility of a cross-section edge length of the square tube of z. B. 500 mm loads of 100 tons or more then take up when the post with a length of 1100 mm approx. 500 mm from the Protrudes from the road surface.

According to a further proposal, the bollard is at least guided by a guide such as Angle iron running parallel to its edges, taken from parallel to itself Double T-bars running along the road surface. This will make a high Stability achieved that even when force is exerted on an extended bollard Twist of the guide does not lead.

To make it easy to move, so that the bollard can be quickly removed and removed To be able to drive in, it is also provided that between the guide and the ratchet post sliding elements are arranged.  

The displaceability from the road surface can be hydraulic, electric motor, by Counterweight or otherwise. There is also the option of removing or Return by remote control or the former z. B. by an embedded in the lane Trigger induction loop.

The invention is illustrated by the following description of in the drawing tem embodiment explained in more detail.

Show it:

Fig. 1 shows a longitudinal section of a first embodiment of a barrier post and

FIG. 2 shows a section along the line II-II in FIG. 1.

In Fig. 1, a bollard ( 10 ) is shown, which is displaceable perpendicular to a road surface, not shown. The bollard ( 10 ) consists of an outer square tube ( 12 ) in which a round tube ( 14 ) is arranged. On the carriageway side, the front sides of the square tube ( 12 ) and the round tube ( 14 ) are covered by a plate ( 16 ) which is preferably welded to the aforementioned elements. From the inside ( 18 ) of the cover surface ( 16 ) there is an unspecified attachment for a hydraulic cylinder ( 20 ) which runs inside the round tube ( 14 ) and via which the bollard ( 10 ) can be raised or lowered. In order to give the bollards high stability, radial reinforcements in the form of gusset plates ( 30 ), ( 32 ), ( 34 ) and (go from the inner edges ( 22 ), ( 24 ), ( 26 ) and ( 28 ) of the square tube. 36 ), which extend up to the outer wall ( 38 ) of the round tube ( 14 ).

Furthermore, between the outer wall ( 38 ) of the round tube ( 14 ) and the inner wall ( 40 ) of the square tube ( 12 ), the stiffeners ( 30 ), ( 32 ), ( 34 ), ( 36 ) having free spaces are filled with concrete, to ensure that the bollard ( 10 ) can take a high load.

The bollard ( 10 ) itself is received in the region of its corners by angle iron ( 42 ), ( 44 ), ( 46 ), ( 48 ), between the angle iron ( 42 ), ( 44 ), ( 46 ) and ( 48 ) and the edges of the square tube ( 12 ) are provided with sliding elements, two of which are provided with the reference numerals ( 50 ) and ( 52 ) by way of example.

The angle iron ( 42 ), ( 44 ), ( 46 ), ( 48 ) itself are welded to double-T-beams ( 54 ), ( 56 ), ( 58 ) and ( 60 ), which run parallel to the surface of the carriageway, and so on to achieve high strength.

With a corresponding construction, in which the square tube has a cross section of 500 mm × 500 mm and a length of 1100 mm, at 500 mm from the road surface protruding bollard ( 10 ) loads of 100 tons and more can be easily absorbed without the Barrier posts or their guides experience deformation. This ensures that even when z. B. against the bollard ( 10 ) drives a motor vehicle, a lowering into the carriageway is possible so that it can be driven on again to the desired extent.
