Definitions
- the invention relates to a safety structure for the Top of a fence.
- a safety structure for the Top of a fence Such as also Constructions called “wall crown protections" for example to protect prison walls as Climbing protections used.
- a safety structure of the type mentioned above is known from the German utility model G 91 01 345.
- the known security construction are those with a Fastening and a boom section equipped Carriers on their counteract a possible attack Side covered with expanded metal. This is the Following the angle between the fastening and the boom section formed angled and is therefore flush the bearers.
- the known construction in the angular range of the carrier a first S-wire roll arranged.
- a second S-wire roll on the top of the fabric, with the Covering and the S-wire roll in the area of the free over the Touch the end of the girder section.
- the well-known fuse construction offers good protection against exceeding.
- An attacker trying to get into the Safety construction of suspended ropes, rope ladders etc. or other aids based on the construction of these to exceed can become free due to the instability of the protruding section of the expanded metal covering not in support sufficiently. It is also made more difficult Overcoming attempt in that with a load of the free protruding section of the expanded metal covering itself the S wire reel supported on this section Attacker tends towards. In this way, the well-known Securing structure due to its compliance effective obstacle that can hardly be overcome.
- the object underlying the invention is an effective, easy to assemble construction of the to create the type explained above.
- the second element made of expanded metal Fence covering is on the bracket of the carrier hung up.
- the expanded metal element is through two bevels running in its longitudinal direction in three Sections divided. This is due to the double fold Expanded metal element, seen from the side, essentially S-shaped educated. Because of this shape it is Expanded metal element with considerable dimensional stability fitted. This keeps its shape Expanded metal element also in the attached state as it is on the boom of the carrier is placed.
- Such a fold of the second Section can be easily manufactured and leads to an optimal stiffening of the expanded metal element. This applies in particular if at the same time the between the second and third sections of the expanded metal element included angle is 90 °.
- the carrier of the construction according to the invention is in the Usually from a steel profile with a rectangular cross section be formed, its end thus have a certain height.
- the width of the second section should therefore preferably be in the be substantially equal to the height of the end of the boom.
- the ratio from the width of the first section to the width of the third Section of the expanded metal element between 1.5 and 2 should be.
- the width of the on the Boom section lying about 435mm and the width of the third section standing freely in the room should be approx. 255mm.
- a flat roller is placed on the expanded metal element.
- a flat roller is essentially an S-wire reel, whose turns overlap in one Level.
- Such flat rollers have in designed state a certain dimensional stability. Under however, they dodge larger loads.
- high elasticity has a flat roller made of stainless steel.
- the section that extends freely beyond the boom of the expanded metal element forms a flat roller effective protection not only against an attacker who with suitable aids to the safety structure depends, but also against such attackers who try to Securing construction using a leaned ladder to overcome.
- the rigidity of the Flat roller no longer out to support the weight of the attacker support.
- the flat roller therefore suddenly gives way with the consequence back that the attacker is in her or one on the Expanded metal element placed additional Securing device, for example an S wire reel, caught.
- the width of the Flat roll about twice the width of the third Correspond to section of the expanded metal element.
- Converting existing security systems to one Security construction according to the invention can thereby be simplified that the boom of the carrier by a in or on the mounting section or clip-on profile piece is formed. With such a It is the design of the construction according to the invention For example, the boom on the To place support posts of an existing fence and then to be covered with the expanded metal covering.
- the securing structure 1 fastened to a wall M has a carrier 2 made of a steel profile with a rectangular cross section, which is divided into a fastening section 2a and a bracket 2b arranged at an angle to the fastening section 2a.
- the fastening section 2a is fastened to the wall M by means of fastening screws (not shown). spaced bores 2c, d of the fastening section 2a are screwed.
- the length L A of the fastening section 2a is 1000 mm in the tested embodiment shown in FIG. 1.
- the boom 2b stands freely from the fastening section 2a of the support 2 at an angle ⁇ of 115 ° from the fastening section 2a.
- the first section 3a of an expanded metal element 3 lies on its upper side 2e, the width b1 of which corresponds to the length of the upper side 2e of the arm 2a.
- a second section 3b which is flush with the free end 2f of the arm 2b of the beam 2, is by folding the expanded metal element 3 along a first folding line 3c and a second folding along a second one which is spaced apart and parallel to the first folding line 3c at a width distance b2 Kink line formed in 3d.
- the third, front section 3e of the expanded metal element 3 lies between the fold line 3d and the front free edge 3f of the expanded metal element 3. It stands freely beyond the end 2f of the boom 2b, essentially being arranged in the extension of the underside 2g of the boom 2b is.
- the ratio of the width b1 of the first section 3a of the Expanded metal elements to the width b3 of the third section 3e is approximately 1.7.
- the width b2 of the second section 3b is substantially equal to the height h of the free end 2f of the Beam 2.
- an angle of 90 ° locked in is in each case in each case.
- a fence element 4 is arranged on the fastening section 2a of the carrier 2. Like the expanded metal element 3, this is made of expanded metal.
- the fence element 4 is divided into two sections 4a, 4b, of which the first section 4a rests on the fastening section 2a of the carrier 2, while the second section 4b is oriented at an angle ⁇ parallel to the underside 2g of the bracket 2b.
- the width Ba of the first section 4a of the fence element 4 is greater than the length L A of the fastening section 2a, so that the lower edge 4c of the fence element 4 projects beyond the lower end of the fastening section 2a in the assembled state.
- a flat roller 5 is placed, the diameter of which Double the width b3 of section 3e corresponds.
- An S wire reel 6 is on the top of the expanded metal element 3 placed in such a way that they 2h in the area of the upper end edge of the boom 2b, on the wall M and on the third section 3e of the expanded metal element 3 is supported.
- a second S-wire reel 7 is in the angular range between the boom 2b and the fastening section 2a of the carrier 2.
- the securing structure 10 shown in Fig. 4 is for Securing the upper edge of an existing fence this has been retrofitted. Form the fence posts 11 of the fence thereby the fastening section of a carrier, the boom 12 over one placed on the top of the fence posts 11 Connection section 12a is connected to the fence posts 11.
- the boom 12 In relation to the fence post 11, the boom 12 is at an angle ⁇ of 115 ° inclined. On its top 12b is a Expanded metal element 13, which the previously described Expanded metal element 3 corresponds. Because the length of the boom 12 shorter than the width of the first section 13a of the Expanded metal elements 13, its rear edge 13b protrudes in assembled state via the lower end 12b of the boom 12 out.
