Description

448 894 of these the elastically deformable steel beam to serve as a catching device.

The interaction between a support beam and the basic element control block can be achieved through various combinations. These combined systems are not only suitable for use as double-sided protection between two carriageways, but can also be used as single-sided protection on the outside of the carriageway. According to a preferred embodiment, the basic elements can be made of concrete, preferably reinforced concrete, and in another embodiment the elements are made of gutter-bent steel plates, and comprise at least one internal support member for the side walls.

In later cases, the weight will be reduced while transport is facilitated. The concrete elements are inelastic, while in the event of a collision the element consisting of steel plates in some men is elastic and deformable.

Additional features of the invention will become apparent from the subclaims and the following description.

The accompanying drawings show by way of example an embodiment of the invention, and use thereof.

Fig. 1 shows a cross-section through yet another embodiment, Fig. 2 shows a perspective view of a detail in the embodiment according to Fig. 1, and Fig. 3 shows a perspective view of the embodiment according to Fig. 1. 3, the support system 50 is supported by cross-sectional base elements 51, made of steel plate. As will be apparent from the following description, the posts 52 of the carrier system 50 may be arranged offset relative to the connecting means 53 between the base elements 51, but it is of course possible to arrange openings in the top plates 54 at the elements so that posts 52 and connecting means 53 can designed in one piece.

The various elements can, for example, be 2 m long, while the support beams 56 are twice as long. It is of course possible to let the beams also be 2 m.

The steel plate 55 in one side of the base element is formed with a 448 894 8 cm high, vertical lower section 57, and an adjoining inclined section 58, which forms an angle of 45 "with the horizontal plane, while an upper section 59 forms an angle of 65 ° with the horizontal plane. The total height of the sliding threshold is approximately 45 cm, and the support beams are mounted so that the entire height of the system is approximately 90 cm.

In a double-sided carrier arrangement, a similar plate 60 is arranged in a mirror-inverted position relative to the plate 55, the upper parts of the plates being connected by means of a top plate 54, to which different support members 53-61 are welded.

The lower edge of the side wall plates 55, 60 is connected by spacers 62, which may optionally be U-profiles, the web 63 of which faces the top plate 54, and which has a length of approximately 70 cm.

In the middle of the body 63 of the spacer member 62, a vertical support member 53 is welded in, and is suitably constituted by an I-beam.

At a distance of 12 to 15 cm from the life of the lower spacer 62 there is a second, shorter spacer 64, which consists of two parts, which from the support member 53 extend to the side wall plates 55 and 55, respectively. 60, and are attached to them, as well as to the support member 53.

Containers 65, 66, which optionally extend between two adjacent beams, are located on the beam web 63, and are arranged to receive ballast material in order to increase the locking capacity of the system. The ballast may be made of suitable heavy material, e.g. scrap.

As can be seen from Fig. 2, the individual basic elements, which for example can have a length of 2 m, can be joined together by means of internal splicing elements 67 at the end sides. The splice elements have the same shape as the side wall plates, and are fastened to them by means of bolts 68. To secure the bolts, lock washers are suitably inserted. - On the steel plates 55 and 60, the sliding ability between the wall and the vehicle wheel in the event of a collision will be significantly less than with the concrete element, so that a rapid ascent of a vehicle wheel is prevented.

The different slopes at sections 57, 58 and 59 at the 448 894 side wall sections mean that the driver gradually notices a collision. The vertical section 57, in the event of a slight collision, prevents the wheel from climbing, which instead slides along this surface. In section 45, which extends in approximately 45 °, in the next step, the vehicle driver, in the event of a stronger shock, draws attention to what is happening; under that section 59, which of course has an even steeper ascent, serves as a transition to a real capture at the steel beams.

Due to the fact that the width is only about 70 cm, the parts of the easily constructable system will only require relatively little storage space, but in the assembled condition effectively prevent passage over the beams. Even in the event of a strong impact, only minor deformation of the arrangement is obtained between opposite lanes. The steel beams prevent the vehicle from passing completely, and due to its deformability will "push back" the vehicle, and also for the most part also prevent the vehicle from turning completely.
