Description

The invention relates to a side protection system for construction sites with securing elements fastened to a plurality of carriers. Such side protection systems serve to counteract during the construction phase crashes of persons or the escape of building material by wind influence.

Side protection systems are known from the prior art, for example, in which transverse slats or grids are attached to the ground-mounted railing posts. It is a disadvantage of these systems that the fastening of the railing posts, which is usually accomplished by means of screws and dowels, is complicated and that only paraphrase-side protection systems can be constructed with reasonable effort. Furthermore, it is known to clamp the construction of a floor-to-ceiling side protection system vertical post between floor and ceiling and then attach to this vertical post suitable security elements. However, the vertical posts are held only by friction between the floor and ceiling, which is a security risk. Finally, also side protection systems are known in which elements are fastened by means of dowels and screws to wall or support elements, which leads in addition to the time required in a disadvantageous way that provided for this purpose holes in the wall or support elements after removal of the side protection system for cosmetic reasons must be closed.

From the US Pat. No. 6,840,015 B1 a side protection system has become known. The side protection system has a safety net arrangement, which is arranged above a roof truss to be erected. The safety net arrangement consists essentially of several nets which extend between above the truss mounted posts.

The US 2004/0135134 A1 discloses a fall protection with a net-like fabric, with vertically spaced fastening straps on

Post can be attached. The posts are fastened by dowels to a ceiling.

From the DE 201 09 216 U1 a roof edge protection for flat roofs has become known. The roof edge protection has a number of vertical, open-topped sleeves, which are mounted on steel parts at a distance from the edge of the roof. Posts are inserted in the sleeves. Along the posts spaced tensioned flexible traction elements are provided at intervals.

Furthermore, the disclosure US 4,815,562 A a barrier to the retention of rubble. The barrier has a woven net. The net is placed on its top on a safety line.

Finally, out of the US 6,182,790 B1 a generic side protection system for construction sites has become known. The known side protection system has a plurality of carriers made of flexible material to which safety nets are attached. The supports of flexible material are stretched under tension in a support structure.

An object of the invention is to provide an improved side protection system which can be easily constructed while ensuring high safety.

According to the invention, this object is achieved by the features of claim 1 and in particular by the fact that each consisting of a flexible material carrier are arranged under tension between each two vertically extending wall or support elements, wherein plate-like or lattice-shaped securing elements that are stiff in itself are releasably connected to at least two vertically spaced carriers.

Instead of the known from the prior art support, which are often formed as vertically extending rigid posts, according to the invention flexible supports are used, which extend generally in the horizontal direction between spaced wall or support elements. Through the use of a flexible material is at least in the horizontal direction a uncomplicated and continuous length adjustment possible, since it is not a problem to put only a portion of a comparatively long flexible support under tension, which corresponds to the distance between the two wall or support elements, whereas the remaining portion of the flexible support can hang freely unused. The attachment of a flexible support to a wall or support member designed according to the invention also extremely advantageous because with support elements and even with narrow wall elements, these elements can be easily wrapped by the flexible support, whereupon the carrier is then placed under tension. In this case, the flexible support forms a loop which engages around the wall or support element without the flexible support having to be fixed to the wall or support element with additional fastening elements such as screws or dowels. In this case, the well-known from the prior art drilling, dowels and screws can therefore be completely eliminated. The same applies to the previously required after removal of the side protection system closing of drilling and dowel holes for cosmetic reasons, since no such holes are needed when a wall or support member is wrapped by a flexible support according to the invention.

If a flexible support according to the invention has to be fastened to a comparatively wide wall element which can not be looped around by the support, it is possible to attach clamps or clamps to the wall element, avoiding boreholes, on which the flexible support is then fastened, in particular suspended can. Alternatively, it is of course also possible to attach a suitable wall connection element by means of screws or dowels to a wall element and then connect the flexible support with this wall connection element.

According to the invention, only very few or no drilled holes in wall or column elements and no drill holes in the floor and ceiling area are required for the attachment of the side protection system, which greatly simplifies the creation of the side protection system according to the invention. Furthermore, it is with the side protection system according to the invention without the provision of elements of different sizes without difficulty possible to adjust the required length of the flexible support continuously. Finally, the wrapping of wall or support elements according to the invention by the flexible support a very secure attachment of this support to the wall or support elements achieved, which, for example, a significant advantage over such side protection systems conditionally, in which vertically extending posts between the floor and ceiling under frictional engagement be trapped.

A further advantage is that the carrier according to the invention can be attached to the wall or support elements when the fitter is still secured by railing elements in a plane below him ceiling formwork. The structure of the side protection system according to the invention is thus possible before the next ceiling is concreted, so that the safety of the technician is given at any time. The safety when mounting the side protection system according to the invention can be additionally increased by a fitter hangs his personal security device on already mounted inventive carriers.

Finally, in the side protection system according to the invention, only an extremely low level of noise results, since no components of this side protection system have to be connected to hollow metal parts, as is often the case in the prior art.

The invention can be realized particularly advantageously if the flexible carrier is made of textile material and configured in a belt shape. Preferably, such a carrier is several centimeters wide and / or at most 5 mm thick. Such carriers are in stable and inexpensive Variants commercially available, can be transported and stored in a space-saving manner rolled up and placed under tension by means of commercially available tension ratchets, so that the side protection system according to the invention can be provided without loss of security with little economic effort.
As an alternative to belt-shaped carriers, however, carriers in the form of cables can also be used, for example.

In a particularly economical variant of the side protection system according to the invention, a support made of flexible material has exactly one tensioning ratchet with which a support arranged between two wall or support elements can be tensioned. In this case, the free end of a support portion having an eyelet and the free end of another support portion having a hook which is dimensioned so that it is movable through the eyelet. This embodiment, which can be mounted by a single installer without difficulty, is described below with reference to Fig. 13 explained in more detail.

Alternatively, each carrier made of flexible material has one or more tensioning ratchets. In the simplest case, the two wall or support elements are within a single loop, which is then placed under tension with a single tensioning ratchet. In this version, only a small number of tension ratchets is required to construct the side protection system according to the invention, however, comparatively large carrier lengths are required because two carrier sections extend parallel to each other between the two located within the common loop wall or support elements, although for securing the security elements a single such section would suffice. In addition, in this variant of disadvantage that they are mounted by a single fitter only with difficulty can be because the carrier before lashing due to gravity on the wall or support elements tends to slip down.

Another alternative way of securing and tensioning a carrier between two wall or support members is to stretch a portion of the support about a vertically extending first wall or support member by means of a tensioning ratchet, and / or a portion of the support by means of a tensioning ratchet is stretched about a vertically extending second wall or support member, and / or a portion of the support is tensioned by means of a tensioning ratchet between two further portions of the support or between another portion of the support and a vertically extending wall or support member.
Hereinafter, for simplification, a support section stretched around a wall or support element by means of a tensioning ratchet is referred to as a "support belt" and a support section extending between two wall or support elements is referred to as a "horizontal belt". Nevertheless, it is possible to form the so-called column and horizontal straps as a rope.

According to the embodiment described above, in which a plurality of tensioning ratchets are used on a plurality of sections of a carrier, it is preferred if in each case a support belt is fixed by means of a respective tensioning ratchet on each wall or support member by clamping. Each of these support straps can then have, for example, one, two or three eyelets or hooks on which a horizontal strap can be fastened in a simple manner. Such, then extending between two support straps horizontal belt can in turn be tensioned by means of a third tension ratchet, whereupon the total of three sections (two support straps and a horizontal belt) existing carrier is fully assembled. Such an assembly can be carried out in a simple manner by a single fitter, since due to the first-time tightening the support straps on the wall or support elements slipping this support straps is reliably prevented.
In another embodiment of the invention, a support belt is clamped on only one of the two wall or support members with a tensioning ratchet, whereupon a horizontal belt attached to this support belt, looped around the other wall or support member, again guided back to the support belt and finally fixed there becomes. Subsequently, this horizontal belt can then be tensioned by means of a tensioning ratchet. In this case, the use of a third tensioning ratchet is saved, but a much greater length of the horizontal belt is required.

Alternatively to the use of a support belt, a carrier or horizontal belt can also be fastened to a wall connection element which is clamped or screwed to a wall element. This is particularly useful when a wall element is dimensioned such that a support belt would be needed with a very large scope. A horizontal belt can be stretched either between two wall connection elements or between a wall connection element and a support belt.

It is particularly preferred if a wall connection element has a fixing section for engagement in a recess of a securing element. In this case, when fixing the securing member to the carrier, the fixing portion can be inserted into the recess of the securing member, whereby the securing member is fixed in the horizontal direction along the carrier. This will avoid in that an excessively large gap is created between the wall element carrying the wall connection element and the securing element adjoining thereto. In addition, a subsequent slippage of this fuse element is effectively countered. In this case, the wall connection element thus has a double function. On the one hand, it offers a mounting option for a carrier or a horizontal belt, on the other hand it fixes a securing element.
When using lattice-shaped securing elements, the fixing section can easily engage in a recess which is present in any case in the lattice grid without having to provide a special recess in the securing element.

The securing elements are fastened to the carriers preferably with coupling elements which each have an open or closed eyelet whose size is adapted to the cross section of the carrier. The coupling elements can be designed as simple bent wire parts. The function of the coupling elements is to prevent movement of the securing elements perpendicular to the carrier or perpendicular to the plane of the securing elements. For this purpose, a suitable latch extension is attached to the eyelet of a coupling element, which is explained in more detail inter alia in the context of the description of the figures.
When using closed eyelets, it is necessary to thread the coupling elements before attaching the carrier to the wall or support elements on the carrier, which then has the advantage that the coupling elements no longer represent separate, lost parts. When using eyelets, however, it is also possible to attach coupling elements to already strained straps.

If a carrier or horizontal belt is stretched over a particularly long length, it is possible to contact the carrier with a coupling element an additionally provided ceiling support, wherein the coupling element can preferably be inserted into a pinhole of such a ceiling support, so as to achieve additional vertical support of the wearer.

When mounting the fuse elements to carriers by means of said coupling elements, the fuse elements are leaned from the inside of the building to the carrier and then fixed with coupling elements to this. If grid-like security elements are used with a corresponding grid grid, these are still vertically movable after fixing by means of the coupling elements over a certain distance. As a rule, such movable securing elements are supported in the vertical direction on the bottom side.

It is particularly preferred if the coupling element has a latch extension which extends obliquely to the limited plane of the eyelet. In this case, the coupling element connected to a belt-shaped support for generating a bayonet lock between coupling element and securing element about a perpendicular to the belt-shaped support axis with slight deformation of the same can be pivoted. In order to enable this pivoting, it makes sense to provide the coupling element with an additional handle portion at which the coupling element can be grasped by the fitter. The last-mentioned embodiment of the coupling element will be explained in more detail in the description of the figures.

Alternatively to the use of the above coupling elements, the securing elements can also be provided with fixedly attached eyelets into which the respective carriers are threaded.

It is particularly advantageous if adjoining securing elements are connected to one another in an articulated manner or can be connected, in particular hooked, wherein preferably each securing element has hook elements on one longitudinal side and lug elements on the other longitudinal side. Likewise, it is also possible to connect adjacent security elements by means of cable ties, straps, straps, wires or ropes articulated with each other. In the case of latticed fuse elements, e.g. the respective mutually facing, outermost vertical struts coupled together. A plurality of hingedly interconnected securing elements are pivotable about an axis extending along their coupling line axis, so that they can be continuously adjusted according to the accordion principle in a simple manner to different widths. It is not necessary to attach each fuse element with coupling elements on the carriers. Rather, for example, two mutually coupled security elements can be V-shaped bent away from a strained support, without themselves being attached directly to the carrier, since these two fuse elements are sufficiently fixed by the adjacent to them further securing elements. The other securing elements are attached to the tensioned carriers with coupling elements. By such V-shaped bent away from the carrier fuse elements can be easily make different width adjustments depending on the bending angle. In addition, it is also possible, for example, to convert columns or columns without interrupting a sequence of horizontally adjacent securing elements. If necessary, more than two securing elements can be bent away from the carrier for this purpose.

It is advantageous if each securing element has two spaced-apart hook elements on one longitudinal side and two correspondingly spaced-apart loop elements on the other longitudinal side, wherein the free end portions of the two hook elements can preferably be formed of different lengths. When inserting the two hook elements of a securing element in the two eyelet elements of an adjoining securing element, the fitter can first concentrate on the hooking of the hook element with the longer free end portion. If this free end portion has been inserted into the associated Ösenelement, then the other hook element can be hung with the shorter free end portion in the second loop element of the adjacent securing element easily. In this way, the coupling of adjacent security elements can be accomplished particularly easily by a single fitter.

The hook elements of a series of a plurality of hooked together securing elements may extend alternately upwards and downwards, in particular, all the security elements are formed equal to each other. The mutually identical design of the fuse elements requires a cost-effective production and storage, since no mutually different security elements must be produced and kept. Alternatively, however, it is also possible within the scope of the invention to provide, for example, fuse elements of two different types, with different types of fuse elements in each case being coupled to one another adjacent to one another.

When the hook elements of the securing elements extend alternately upwards and downwards, it is advantageous if the securing elements are hooked together in pairs before being fastened to the carrier and then subsequently coupled as a pair of securing elements with securing elements already fastened to the carrier. This makes it possible, depending on the orientation of the first mounted on the carrier Fuse element to thread the pairs of securing elements either from above or from below on the securing elements already attached to the carrier. When securing elements are supported on the bottom side, they are usually threaded from above, if they are to be adjacent to a ceiling, from below.

According to the invention, it is possible to support the first securing elements on the bottom side and to connect the horizontal struts of second securing elements to adjacent horizontal struts of the first securing elements in a force-locking manner, in particular first and second securing elements overlapping one another in the vertical direction. The frictional connection can be made in any way, in particular by means of cable ties, straps, straps, wires or ropes. All these means make it possible to adapt the length of the loop, which connects the two horizontal struts with each other, to the respective conditions. Such an arrangement of overlapping in the vertical direction rows of fuse elements is particularly useful when a floor-to-ceiling protection is to be created.
Instead of the provision of said non-positive connection, the second securing elements can also be supported on coupling elements which hold the first securing elements on a carrier.

If the rows of securing elements arranged vertically offset from one another are frictionally connected to one another in the manner described, an additional stability of the overall arrangement can be achieved in that two of each of the four securing elements adjoin one another horizontally and at the same time two mutually adjacent ones Overlap vertical direction, and vertical struts are positively connected to each other. It is important to ensure that vertical struts of all four security elements connected to each other, eg with cable ties. In this way, a composite of four securing elements can be generated, the height of which can be adjusted individually by the loop length of the frictional connection between the horizontal struts.

The fuse elements which can be used within the scope of the invention are preferably designed in the form of lattices. However, it is also possible to use tensioned nets, wood panels, plastic panels, Plexiglas panels or the like in a frame. The securing elements explained above, which can be connected to one another in an articulated manner, can also be used as conventional fence elements without the supports according to the invention.

An advantage of the invention is also to be seen in the fact that only very few different parts are needed. It is sufficient to provide each with the same trained fuse elements, column straps, horizontal straps, wall connection elements and coupling elements to close openings in structures of any size virtually seamlessly with little effort.

Further preferred embodiments are explained in the subclaims and in the description of the figures.

The Fig. 1 and 2 show a fuse element used in the invention in the form of a grid, which is formed with vertical struts 12 and horizontal struts 14. Such a securing element 10 may for example have dimensions of 200 cm x 60 cm and a weight of approximately 7.5 kg, so that it is easy to handle by a single fitter. Other dimensions and weights are also possible. The fixed by the vertical struts 12 and the horizontal struts 14 grid can be, for example, 20 mm x 100 mm. Again, other dimensions are possible.
Such, in its basic form rectangular securing elements 10 can be mounted according to the invention both horizontally or vertically extending carriers in both vertical and horizontal orientation.

The second horizontal strut 14 from above is at its left end as a hook member 16 with a long, vertically extending upwards free end portion 18 is formed. In a corresponding manner, the left end of the second horizontal strut 14 is formed from below as another hook member 19 with a short, vertically upwardly projecting free end portion 21.

The free end portions 18 and 21 are located within edge-side recesses 20 of the securing element 10, so that they continue the grid of the vertical struts 12 substantially. This arrangement allows the coupling of two fuse elements 10 without the formation of a relevant gap between them.

The hook members 16, 19 opposite right ends of the respective horizontal struts 14 are each formed as Ösenelemente 22, which are also located within edge recesses 24 of the securing element 10, in turn, to allow a largely gap-free coupling of two securing elements 10. The eyelet elements 22 extend in a direction perpendicular to the vertical struts 12 and the horizontal struts 14 extending plane, so that two hook elements 16, 19 of a further securing element 10 easily into the eyelet elements 22 of the in the Fig. 1 and 2 illustrated fuse element 10 can be introduced.

The two horizontal struts 14, which are provided with hook and loop elements 16, 19, 22, are each in two parts and formed overlapping in the middle of the securing elements 10 so as to facilitate the manufacture of the two parts of the horizontal struts 14. However, a one-piece design of the horizontal struts 14 is possible. One of the two parts of these horizontal struts 14 has in each case the hook elements 16, 19 and the other part of the eyelet elements 22.

Fig. 3 shows on the left a securing element 10, which is hooked with its hook element 19 with a short free end portion 21 from above into an eyelet member 22 of a further securing element 10 shown on the right. The free end portion 21 extends vertically downwards.

In a similar way shows Fig. 4 left a fuse element 10, which was introduced with its hook member 16 with a long free end portion 18 from below into the eyelet member 22 of a further securing element 10 shown on the right. The free end portion 18 extends vertically upwards.

The Fig. 3 and 4 thus illustrate that securing elements 10 can be mounted on already mounted securing elements 10, on the one hand, by virtue of their hook elements 16, 19 from above (FIG. Fig. 3 ) as well as from below ( Fig. 4 ) are inserted into the eyelet elements 22 of the already mounted securing elements 10. Alternatively, it is of course also possible to mount fuse elements 10 with their eye elements 22 from above or from below onto the hook elements 16, 19 of already mounted securing elements 10 or threading them on.

The Fig. 3 and 4 show that in conjunction with Fig. 1 described marginal recesses 20, 24 ensure that there is no gap between coupled fuse elements 10, which is substantially greater than the distance between two adjacent vertical struts 12 so that a largely continuous grid can be generated by coupled security elements 10.

• Wenn beispielsweise das links dargestellte Sicherungselement 10 bereits montiert ist und alle Sicherungselemente 10 bodenseitig abgestützt werden sollen, werden zuerst die beiden mittleren Sicherungselemente 10 miteinander verhakt und dann als Paar von oben auf die Hakenelemente 16, 19 des links dargestellten Sicherungselements 10 aufgefädelt. Anschließend kann dann ein weiteres Paar von Sicherungselementen 10 oder ein einzelnes Sicherungselement 10 von oben auf die Hakenelemente 16, 19 des dritten Sicherungselements von links gemäß Fig. 5 aufgefädelt werden.

Fig. 5 shows in plan view four mutually coupled securing elements 10, wherein it can be clearly seen that the hook elements 16, 19 of the individual, successive securing elements 10 extend alternately upwards and downwards. When mounting the fuse elements 10 according to Fig. 5 the procedure is as follows:

• For example, if the fuse element 10 shown on the left is already mounted and all securing elements 10 are to be supported on the bottom side, first the two middle security elements 10 hooked together and then threaded as a pair of top on the hook members 16, 19 of the fuse element 10 shown on the left. Subsequently, then another pair of securing elements 10 or a single securing element 10 from above on the hook elements 16, 19 of the third securing element from the left according to Fig. 5 be threaded.

If the securing elements 10 are to be mounted adjacent to a ceiling and the two securing elements 10 shown on the left are already mounted, for example, the two securing elements 10 shown on the right are first hooked together and then as a pair of bottom on the hook elements 16, 19 of the second securing element 10 of left according to Fig. 5 threaded. Accordingly, then further security elements in pairs or individually to the in Fig. 5 shown fuse elements 10 are coupled.

Since the hook elements 16 have a longer free end portion 18 than the hook elements 19, a fitter may first focus on threading an eyelet member 22 onto the free end portion 18 and then threading the further eyelet member 22 onto the free end portion 21. During the second threading is the first loop element 22 is already connected to the hook element 16 so that the fitter can concentrate on the threading of the second loop element 22 onto the hook element 16. The same applies to the insertion of hook elements 16, 19 in Ösenelemente 22nd

Fig. 6 shows a three-dimensional representation of an arrangement according to Fig. 5 , but here only three securing elements 10 are shown.

Fig. 7 shows three-dimensional view of three fuse elements 10, which were tipped like an accordion against each other. This tilting is possible because the hook elements 16, 19 inserted into the lug elements 22 have the effect of hinges which enable pivoting of the securing elements about the axis of the free end sections 18, 21 of the hook elements 16, 19. By this possibility of pivoting, the total width of several coupled fuse elements 10 can be adjusted continuously. An enlarged swivel angle causes a shortening of the total width of such a series. Furthermore, the pivoting opens up the possibility, for example, to rebuild columns with fuse elements 10 coupled according to the invention, as in conjunction with FIG Fig. 12 will be explained in more detail below.

Fig. 8 shows two by means of hook member 16 and eyelet member 22 coupled together securing elements 10 which are fixed to a horizontally stretched belt-shaped support 26, wherein here is a view of a building inside is shown. A view from the outside of the building is in Fig. 9 represented, wherein here the coupling of the two securing elements 10 by means of the hook member 19 and the eyelet member 22 is shown. The carrier 26 runs in this representation before the Securing elements 10, whereas he according to Fig. 8 runs behind the fuse elements 10.

According to Fig. 8 and Fig. 9 In each case a securing element 10 is connected by means of a coupling element 28 to the carrier 26, wherein the coupling elements 28 according to Fig. 8 and Fig. 9 are formed identical to each other.

The coupling element 28 has an open eyelet 30 whose shape is adapted to the cross section of the belt-shaped carrier 26. The eyelet 30 of the coupling element 28 can either be threaded onto it before tensioning the carrier 26 or an already tensioned carrier 26 can, with a certain deformation thereof, pass through the opening of the eyelet 30 (visible in FIG Fig. 8 ) are introduced into this. Since the carrier 26 has the shape of a belt and the shape of the eyelet 28 is adapted to the shape of the carrier 26, it is not possible to rotate the coupling element 28 over a larger angular range about the longitudinal axis of a tensioned carrier 26. In this respect, it is ensured that an extension 32 of the coupling element 28 extending perpendicularly from the eyelet 30 perpendicular to a securing element 10 through its vertical struts 12 is held relatively stably in its position. The extension 32 merges into a substantially U-shaped bent grip portion 34, on which a fitter can grasp the coupling element 28 and twist it with slight deformation of the carrier 26 about the axis of the extension 32.

The handle portion 34 is followed by a latch extension 36, which extends obliquely to the plane bounded by the eyelet 30 and thus engages behind a vertical strut 12 together with a securing portion 38 projecting from it in the direction of the support 26 that a bayonet locking between coupling element 28, carrier 26 and securing element 10 results.

When establishing a connection between the carrier 26 and securing element 10, the securing element 10 is ajar from the building inside to the carrier 26, so that the handle portion 34 extends at least one coupling element 28 through two vertical struts 12 of the securing element. Then a fitter grips the handle portion 34 and twists it at the in Fig. 8 illustrated arrangement in a clockwise direction such that the latch extension 36 extends in the vertical direction downwards. In this case, the belt-shaped carrier 26 is slightly deformed by the eyelet 30. In this position, the latch extension 36 can then be moved with the subsequent thereto securing portion 38 by the two vertical struts 12 of the securing element 10 therethrough, until the vertical struts 12 contact the carrier 26. Then the fitter releases the grip section 34, whereupon the carrier 26, which is under tension, is again demolded, thereby aligning the loop 30 vertically. This leads to the latch extension 36 with its securing portion 38 back into the in Fig. 8 shown position moves in which he engages behind a vertical strut 12 and thereby fixes the securing element 10 on the carrier 26. The decoupling of securing element 10 and carrier 26 runs in the reverse order.

According to the invention, it is not necessary to fix each securing element 10 of a series of securing elements 10 coupled to one another by means of coupling elements 28 on the carrier 26. Rather, here some fuse elements 10 can be recessed without further ado, as these on the hook connections 16, 19, 22 in a sufficient manner to such security elements 10, which in turn are coupled to the carrier 26.

Fig. 10 shows a trained in a curved facade building opening 40, which is bounded by a bottom 42, a ceiling 44 and two columns 46.

On both columns 46, three column belts 48 are vertically spaced from each other by means of tensioning ratchets 50. The Säulengurte 48 each have at least one eyelet 52, in which the ends of a horizontal belt 54 can be hooked.

In each case two column straps 48 of the two columns 46 located at the same height are connected to one another via a horizontal belt 54, which in turn likewise has a tensioning ratchet 50, with which it can be tensioned between the two columns 46. A unit comprising two column straps 48 and one horizontal band 54 represents a carrier 26 according to the invention. When mounting such a carrier 26, first the two column straps 48 with their tensioning ratchets 50 are fixed to the columns 46. Subsequently, the horizontal belt 54 is hooked with its two ends in the eyelets 52 of the column straps 48 and then tensioned by means of a tensioning ratchet 50. This process can easily be performed by a single installer.

In the right outer area of the Fig. 10 It can be seen that the column straps 48 each also have a further eyelet 52, in which further horizontal straps 54 can be hung, which then become an in Fig. 10 not shown, right of the right pillar of the Fig. 10 extending column, which illustrates that the inventive Side protection system in the horizontal direction can be continued as desired.

Approximately in the middle between the two columns 46 according to Fig. 10 is a ceiling support 56 is arranged, wherein the horizontal straps 54 rest on the outside of the building on this ceiling support 56, so that the horizontal straps 54 are each bent slightly in the area of the ceiling support. This ensures that the side protection system according to the invention extends to a maximum extent on the building exterior, so that the working space inside the building is not limited. In addition, it is possible to support the horizontal straps 54, for example by means of coupling elements 28 on the ceiling support 56 in the vertical direction, so as to achieve additional stability.

In the Fig. 10 illustrated fuse elements 10 are connected by means of coupling elements 28 according to the Fig. 8 and 9 coupled to the two lower horizontal straps 54, which extend parallel to each other. It is - as already mentioned - not necessary to connect each fuse element 10 with the horizontal straps 54. Rather, for example, those securing elements 10, which are located in the area of the ceiling support 56 or in the region of the columns 46, can be slightly swung away from the horizontal belts 54, without being directly coupled to them.

The function of the uppermost horizontal belt 54 according to Fig. 10 follows from the representation of Fig. 11 which is essentially the representation of Fig. 10 corresponds, but additionally has an upper row of fuse elements 10. By the two superposed, overlapping rows of fuse elements 10 is in contrast to Fig. 10 created a room-high side protection. The upper Row of security elements 10 is connected by means of coupling elements 28 with the upper two horizontal straps 54. The dead weight of the securing elements 10 of the upper row is received by coupling elements 28 which are coupled to the middle horizontal belt 54. At these coupling elements 28 and at their extensions 32 (see Fig. 8 ) Support horizontal struts 14 of the upper row of fuse elements 10 from. As already mentioned above, it is alternatively and preferably possible to non-positively connect adjacent horizontal struts 14 of vertically overlapping lower and upper securing elements 10, which can be accomplished, for example, by means of cable ties.

Fig. 12 illustrates how a rectangular or round column 46 can be converted with a side protection system according to the invention. On the column 46, a pillar belt 48 is lashed by means of a tensioning ratchet 50, from which horizontal belts 54 extend in opposite directions. Fig. 12 shows that only the leftmost securing element 10 and the second securing element 10 are held from the right by means of coupling elements 28 on each a horizontal belt 54. The coupling element 28 shown on the right is provided in the region of the outermost vertical strut 12 of the respective securing element 10, so that the latter can be pivoted away from the horizontal belt 54 about this vertical strut 12. The two securing elements 10, which connect to the fuse element 10 shown on the left, are not coupled with horizontal straps 54, so that a total of the kinked course of fuse elements 10 according to Fig. 12 can be achieved, with a column 46 is convertible.

Fig. 13 shows two vertically spaced columns 46, between which a carrier 26 'is stretched. The carrier 26 'consists of a Tensioning ratchet 50, are attached to the commercially available two carrier sections, which can be braced against each other with the tensioning ratchet 50. A first short support section has an eyelet 58 at its free end facing away from the tensioning ratchet, whereas a second, long support section has a hook 60 at its free end facing away from the tensioning ratchet. Furthermore, an additional eyelet 59 is threaded onto the long support section.

• Der lange Trägerabschnitt wird um die Säule herum geschlungen und mit dem Haken 60 voraus durch die Öse 58 gefädelt. Auf diese Weise ergibt sich eine Schlinge, welche die Säule 46 umgibt. Die auf den langen Trägerabschnitt aufgefädelte zusätzliche Öse 59 wird so positioniert, dass sie im Wesentlichen gegenüber der Öse 58 zu liegen kommt. Anschließend wird dann der Haken 60 in die Öse 59' eines bereits montierten Trägers 26" eingehängt, woraufhin ein Verspannen des Trägers 26' mittels der Spannratsche 50 erfolgt. Dieser Spannvorgang bewirkt - da der lange Trägerabschnitt in der Öse 58 frei beweglich ist - zum einen ein Spannen desjenigen Trägerbereichs, der sich zwischen den beiden Säulen 46 befindet und zum anderen ein Festzurren der Schlinge, die die Säule 46 umgibt. So wird durch die Betätigung einer einzigen Spannratsche der komplette Träger 26' zwischen zwei Säulen 46 gespannt und zuverlässig fixiert, wobei gleichzeitig nur eine minimale Trägerlänge benötigt wird.

In the case of the affixing of said support to a column 46, which is preferably carried out by a single fitter, the following procedure is adopted:

• The long beam portion is looped around the column and threaded through the eyelet 58 with the hook 60 in advance. In this way, a loop which surrounds the column 46 results. The threaded on the long support portion additional eyelet 59 is positioned so that it comes to lie substantially opposite to the eyelet 58. Subsequently, the hook 60 is then hooked into the eyelet 59 'of an already mounted support 26 ", whereupon the support 26' is braced by means of the tensioning ratchet 50. This tensioning action causes - since the long support section in the eyelet 58 is freely movable - on the one hand a tensioning of that support region, which is located between the two columns 46 and on the other a lashing of the loop which surrounds the column 46. Thus, by the operation of a single tensioning ratchet, the complete support 26 'between two columns 46 is tensioned and reliably fixed At the same time only a minimum carrier length is needed.

In relation to Fig. 13 described support structure can be used in conjunction with all the embodiments described above in an advantageous manner.

Fig. 14 illustrates the fact that the securing elements 10 according to the invention explained above can be stacked, stored and transported in a particularly advantageous manner in a space-saving manner.
The invention is not limited to the embodiments explained above. The scope of the invention is defined solely by the following claims.
