Description

Protective construction

DESCRIPTION

[0001] The invention relates to a protective construction according to the preamble of claim 1.

[0002] A protective construction of this type is known for example from documents DE-A-1 057 157 or US-A-2014/0196382. 5

[0003] Against the generic protective construction, the present invention aims to create a protective construction of the type indicated in the preamble of claim 1, which allows efficient energy absorption against stone impacts, wood impacts, avalanches or similar and that can be assembled and disassembled easily.

[0004] This objective is achieved by the features of claim 1. 10

[0005] Accordingly, according to the invention a protective construction is created, which has at least one support, although usually a plurality of supports arranged at a distance from each other. The supports can be arranged, for example, on a mountain slope on which it is to be built. A collection network is guided on the supports. Each support is arranged in an assigned base plate, with the help of which the supports are fixed in the subsoil, for which anchors and / or micropiles are used. fifteen

[0006] According to the invention, at least one of the supports, although usually each support is fixed by means of a spherical joint in the assigned base plate. The spherical joint has a cavity and a guided ball therein, which is secured by a retention device in its position in the cavity.

[0007] In this way, the advantage is first achieved that the support can be inclined with respect to the base plate by a rotation of the spherical joint and can also be rotated around its vertical axis, also with respect to the base plate. This results in the advantage that the supports can be optimally adapted to the conditions of the place of application in terms of orientation.

[0008] This in turn results in the advantage of an increase in the efficiency of energy absorption in case of impacting objects against the collection network of the protective construction according to the invention.

[0009] The provision of a retention device entails the advantage that the ball can be prevented from leaving the cavity 25, when an object hits the collection net by consequently acting forces on the support (s), which could cause exit of the ball from the cavity.

[0010] According to the invention it is possible to fix the ball of the spherical joint in the support or in the base plate and correspondingly the cavity in the base plate or in the support.

[0011] The dependent claims indicate preferable variants of the invention. 30

[0012] In particular, it should be noted that the base plate can be optimized in terms of weight by making recesses in the base plate itself and / or in the cavity, if it is fixed in the base plate.

[0013] In addition, it is possible to provide fastenings in the base plate, through which support bars can be passed, so that the base plate can be easily transported to its place of application.

[0014] Other details, features and advantages of the present invention result from the description set forth below in some embodiments with the help of the drawing.

[0015] A protective construction 1 according to the invention is shown in a somewhat simplified way in Figure 1, FIG. 2 showing a side representation. 10

[0016] The protective construction 1 has a so-called "support structure" which, as a rule, is formed by a plurality of supports 2 (also: supports), which can be fixed by means of anchors 53 and 54 in the subsoil or floor U of a slope H, as shown in the case of the example shown. According to the construction length of the protective construction 1, a plurality of supports of this type are provided, of which in Figure 1 the support 2 is visibly represented, representing all the supports. If a plurality of 15 supports 2 are provided, these are positioned at distances that can be chosen next to each other on the H slope. However, in principle it is also possible that only such a support 2 is provided, usually , as already mentioned above, however, a plurality of supports 2 arranged at a distance from each other is provided.

[0017] The protective construction 1 also has a collection network or network 3, which is guided by a carrier cable / s arrangement 44 in the area of a support head 47 of the support 2 shown in FIGURES 20 1, it being possible that the arrangement of carrier cable (s) 44 comprises one or two upper carrier cables.

[0018] In the area of the support foot 55 of the support 2, an arrangement of carrier cable / s is provided / is lower / is 46, which can in turn comprise one or two lower carrier cables.

[0019] Between the arrangement of the carrier cable / s / is higher / is 44 and the arrangement of the carrier cable / s / is lower / is 25 46, in the case of the example shown, especially preferable, a cable arrangement / s central / en 45. The central cable / s arrangement / s 45 may have one or more central cables, as in the case of the example, four central cables. The central cable / s arrangement / s is 45 or its central cables can be guided here by means of guide devices in the support 2. The guide devices can be made here for example also as shackles. 30

[0020] Furthermore, the embodiment of the protective construction 1 according to FIGURE 2 shows that an upper bracing cable or a mountain side retention cable 49 is provided. The upper bracing cable 49 fixes the support head 47 of the support 2 by means of a fixing device 52 (rock anchor / ground anchor / anchor) in the subsoil U of the slope H. In the embodiment shown in FIGURE 2, a brake element 51 is also provided in the cable bracing 49. 35

[0021] As also shown in FIGURE 1, a base plate 4 is provided, on which the support 2 visible in FIGURE 1 is mounted. If a plurality of supports 2 of this type is provided, each support 2 is provided with a plate assigned base 4 and is fixed by means of it in subsoil U.

[0022] According to the invention, the support is fixed by a spherical joint 5 on its assigned base plate 4, which will be explained in more detail below, referring to Figures 2 to 6. 40

[0023] For this, reference will first be made to the representations of FIGURES 2 to 4.

[0024] As seen in particular in FIGURES 2 and 3, the spherical joint 5 has a cavity 6, which in the case of the example is fixed on the base plate 4, for example by welding. The spherical joint 5 presents

furthermore a ball 7, which in the case of the example is connected by a connecting piece 57 with the support 2, which in Figure 2 is symbolized by its lower end plate. The ball 7 is further arranged in a ball housing space 56 of the cavity 6, so that the support 2, as shown in FIGURE 2, can be rotated around the center M of the ball 7, as well as around of its vertical axis A.

[0025] The base plate of the support 2 is provided with two drain holes 58 and 59, which serve to allow liquid 5 to enter the support 2, if it is a hollow support.

[0026] In addition, FIGURES 2 and 3 show that a recess 17 is provided on the base plate 4 or in the cavity 6, which serves to reduce the weight. As FIGURE 4 shows, recesses 60 and 61 are also provided at the edges, which also serve to reduce the weight of the base plate 4.

[0027] The protective construction 1 according to the invention is further provided with a retaining device 8, whose structure results in particular from the representation of FIGURES 3, 5 and 6, which will be referred to below.

[0028] Correspondingly, the retention device 8 has two retention fingers or L-retention levers, which are rotatably held by rotating bolts 11 or 14. As shown above all in the representations of Figures 5 and 6, the bolts swivels 11, 14 are passed through recesses 25 or 15 29 and 29 in clamping plates 19, 20 or 21, 22 and thus pass through a recess correspondingly oriented in the corresponding clamping finger 9 or 10, so that this clamping finger can be turned from an open position (clamping finger 9) to a clamping position (clamping finger 10), as shown in Figure 5.

[0029] For fixing the clamping fingers 9, 10 in the clamping position, security bolts 12 or 13 are provided with handles 18 or 18 'assigned, which can be passed through recesses 23, 24, 26, 27 assigned on the clamping plates 19 to 22 and recesses disposed correspondingly on the retaining fingers 9 and 10, as shown in the example of the clamping finger 10 in FIGURE 5.

[0030] The clamping plates 19 to 22 are respectively fixed to the base plate 4, preferably by welding. 25

[0031] In the clamping position visible in FIGURE 3 of the retaining fingers 9 and 10, the guide surfaces 15 or 16 rest on the spherical surface of the ball 7, the configuration of the guide surfaces 15 and 16 being adapted to the corresponding spherical surface. As FIGS. 5 and 6 show, the cavity 6 has a recess in its upper circumference respectively for the fitting of the assigned holding fingers 9 and 10, being visible in these FIGURES only the recess 30, which is assigned to the holding finger 9 However, a corresponding opposite recess is also provided, which by the arrangement of the retaining finger 10 is not visible in the holding position.

[0032] As can also be seen in the representations of FIGURES 5 and 6, an arrangement of two trapezoidal plates 35 and 36 is also fixed on the clamping plate 4, preferably by welding, which respectively have through recesses 37 or 38, which They are aligned with each other. These through recesses 37 and 38 35 are provided on the outer side of the clamping plate 4 in the area of the trapezoidal plates 36 and 37, that is, on the outside of the ground anchor 54, which entails the advantage that Bottom carrier cables that have been passed through these through recesses 37 and 38 cannot come into contact with the support 2.

[0033] On the opposite side, on the base plate 4, two half-shells 31 and 32 are oriented towards each other with their domes, being preferably joined by welding. The two half-shells 31 and 32 are connected to each other by means of a connection piece 33, which is arranged at a distance that can be chosen from the base plate 4, so that a through recess 62 between the connection piece 33 and the motherboard 4.

[0034] As FIGURE 6 shows, a support bar 34 can be passed through this through recess 62.

[0035] In addition, it is possible to pass another support bar 39 through the through recesses 37 and 38 arranged in an aligned manner of the trapezoid plates 35 or 36, as shown in FIGURE 6. FIGURE 6 shows 45

correspondingly the transport state of the base plate 4, whose weight can be approximately 80 kg, so that the provision of support bars 34, 39 considerably facilitates transport for the assemblers.

[0036] FIGURE 7 shows a particularly preferable embodiment of a support 40, which is a so-called fish belly beam. The fish belly beams 40 of this type have curved support tubes 41 and 5 42, which can be seen in the plan view from above of FIGURE 7, which are joined together by a frame structure 43 between yes. The framing structure 43 shown in FIGURE 7 is only an example for a possible arrangement of a plurality of framing bars arranged at an angle to each other, although they can also be made in another way as shown in the FIGURE 7. 10

[0037] In addition to the fish belly beams 40 especially preferable according to the representation of FIGURE 7, already known beam supports, such as double T-beams, can also be used.

[0038] In the protective construction according to the invention other support constructions in principle suitable for protective constructions are also possible.

[0039] In addition to the previously described written description of the invention, reference to the representation of the invention in the drawing is explicitly made to complete the description herein in FIGURES 1 to 7, in particular with respect to its geometric shape and du provision presented by the elements with respect to each other.
