Definitions
- the present invention relates to a cover for scaffolding.
- scaffolding is assembled on the ground in front of a building which is undergoing restructuring or other kinds of work and either connects a series of linear tubular metallic sections to each other or a number of prefabricated frames, which are anchored to the building itself in such a way as to create a complex structure on several working levels which extend from the ground to at least a top of the building.
- the cover of the tubular scaffolding itself is arranged substantially in correspondence with the top of the building, and is generally defined by the last working level, which functions as a cover.
- This kind of cover presents some disadvantages which, briefly, may be summed up in its inadequate capacity to provide protection from atmospheric agents, above all rainfall, and its inadequate capacity to provide drainage of the rainfall itself and, finally, considering that usually this last working level is normally in an exposed position in relation to an outline of the building, in the sail effect that such a last working level can exercise on the entire scaffolding above all when air currents, even of moderate intensity, occur.
- the aim of the present invention is to produce a cover for scaffolding, which will be able to provide effective protection from atmospheric agents such as rainfall for the tubular scaffolding beneath it and which will also be able to provide drainage and will, above all, guarantee the static and dynamic safety of the relative tubular scaffolding even when air currents of considerable intensity occur.
- a cover for scaffolding will be produced which is arranged in an overhanging position on a building which is undergoing construction work and presenting an upper peripheral edge, the cover being characterised by the fact that it comprises a support frame which may be coupled to a top of the tubular scaffolding itself, and an inclined covering shelf, which is connected in such a way that it may be selectively disengaged from the said frame, which extends starting from at least the upper peripheral edge into space and at least beyond the tubular scaffolding.
- the number 1 refers to a cover in its entirety for scaffolding 2.
- the scaffolding 2 is frontally anchored to a building 3, which is undergoing construction work, and presents an upper peripheral edge which is defined, as in the example illustrated, by a gutter channel.
- the scaffolding 2 comprises a number of vertical piers 5, which are placed at regular intervals with equal modular spans, usually equal to 1.8 metres, and they are connected to each other by means of horizontal braced stringers 6 in order to support a number of working levels 7 which are arranged at substantially regular intervals one from the other.
- the piers 5 present respective base portions (which are not illustrated) which are connected to the ground by means of pins or strips, and respective top portions 8 which are connected to the cover 1, and which are constrained to the cover 1 itself by means of joints 8a of a well-known type.
- the cover 1 comprises a support frame 9 which is mounted on and constrained to the portions 8, and an inclined covering shelf 10, which is connected in such a way that it may be selectively disengaged from the frame 9, and which extends starting from at least the channel 4 into space and at least beyond the scaffolding 2.
- the cover 1 comprises a dynamic connecting device 11, which is interposed between the frame 9 and the shelf 10 themselves in order to connect the frame 9 and the shelf 10 to each other in such a way that they may be dynamically disengaged from each other.
- the frame 9 comprises two lateral walls 12 which are arranged at a distance one from the other which is equal to the above-mentioned modular span, and a number of connecting strap irons 13, which connect the two walls 12 and which are transverse to the two walls 12 themselves.
- the walls 12 are produced by means of linear elements which are connected to each other, and each comprises an upper cross member 14 which is connected to the cross member 14 of the other wall 12 by means of the strap irons 13, and two linear tubular base elements 15 and 16, which are engaged in the piers 5, and of which the element 15 presents a length which is greater than a length of the element 16, and is arranged directly facing the building 3. Furthermore, each wall 12 comprises a respective lower cross member 17, which is arranged transverse to the relative elements 15 and 16, and is firmly connected to both the relative elements 15 and 16 in order to define, furthermore, a respective lower engaging portion 18 for mounting the cover 1 onto the scaffolding 2 and anchoring the cover 1 by means of the joints 8a.
- each wall 12 comprises an intermediate linear tubular element 19, which is interposed in an intermediate position between the relative elements 15 and 16 parallel to the elements 15 and 16, and which connects the cross members 14 and 17 to each other.
- the different lengths of the elements 15 and 16 confer on the walls 12 an external perimeter shape which is substantially trapezoid, and impose on the relative cross member 14 a determined inclination into space, or rather opposite the building 3, and in relation to the relative cross member 17.
- the frame 9 comprises a projecting portion 20, which is firmly connected to the elements 15 in order to extend opposite the elements 16 in relation to the elements 15 themselves in such a way as to be arranged at least beyond the channel 4, and comprising two tubular uprights 21 which are parallel to the cross members 14, and a tubular support rod 22 which is transverse to the uprights 21 and which is integral with a top edge 23 of the shelf 10.
- the uprights 21 are engaged on one side by the elements 15 and on the opposite side by the rod 22, which is in turn connected to a terminal end portion 24 of each of the cross members 14.
- each portion 24 extends in such a way as to project beyond the relative element 15, and presents a respective elbow 25, which makes the relative cross member 14 and also the shelf 10 curve towards the rod 22.
- the portion 20 comprises, for each upright 21, a reinforcing element 26 which is arranged along the relative upright 21 transverse to the upright 21 itself, and integral with both the latter and with the relative portion 24.
- the inclined covering shelf 10 is produced by means of a continuous sheet of waterproof material, and is suitable for being rolled up into a sheltering configuration around the rod 22, as it is also suitable for being arranged in an operational shielding position, with the respective lateral edges 27 along the cross members 14 and in contact with the cross members 14 themselves and constrained thereto by the device 11.
- the shelf 10 comprises a main surface 28 which extends into space in order to cover the scaffolding 2 from above, a secondary inclined surface 29 opposite the surface 28 and which extends beyond the channel 4, and a separating ridge 30 between the two surfaces 28 and 29 identified by the elbows 25, which are arranged substantially in a vertical position on the channel 4 permitting the shelf 10 itself to cover and shield completely the scaffolding 2 from bad weather.
- the double surface configuration of the shelf 10, with the surface 28 being of a greater extension in comparison with the surface 29, not only permits the protection of the scaffolding 2 from atmospheric precipitations, but also permits the drainage of such precipitations both towards the channel 4 and towards the outside of the scaffolding 2 itself thus avoiding the necessity to interrupt the construction work in progress.
- the dynamic connecting device provides for disengaging the shelf 10 from the cross members 14.
- the device 11 is shared by the two walls 12 and by the shelf 10, and, as is better illustrated in FIGURE 2, it comprises, for each cross member 14, a number of pins 31 which are provided with respective blocking heads 32, and, for each edge 27 of the shelf 10, a ceding ring 33 which is engaged to a relative pin 31 in such a way that it may be disengaged from it.
- the ceding capacity of the rings 33 is determined by the elasticity of the material from which the rings 33 themselves are made, or by a geometrical conformation of the rings 33 themselves, in relation to the relative heads 32.
- each ring 33 together with the relative head 32 may be configured as a common, well-known type of pressure fastener.
- the ceding capacity of the rings 33 determines the maximum bearing force which may be supported by the shelf 10 before it becomes detached from the cross members 14 remaining hooked to the frame 9 only along its own top edge 23 in correspondence with the rod 22.
- Each pin 31 is mounted along the cross member 14 transverse to the cross member 14 itself, and comprises a tubular body 34 which is mounted in a respective passing hole 35 which is obtained through the cross member 14, and a blocking screw 36 which is arranged on an opposite end of the body 34 in relation to that which corresponds to the relative head 32 in order to axially block the body 34 itself in relation to the relative hole 35.
- the cover 1 When in use, the cover 1 is mounted onto the scaffolding 2 in such a way that, as has already been described, the secondary surface 29 extends beyond the channel 4 of the building 3, and the main surface 28 presents its own overhang into space, or rather towards the external part of the scaffolding 2 itself.
- the equality of the distance of the walls 12 from the cover 1 and the span of the intervals of the scaffolding 2 is, as aforementioned, a modular measurement in the scaffolding field, and it renders the operations of mounting and anchoring much simpler and faster. Nonetheless, in the case of particular applications, the distance between the two walls 12 may also be of a different measurement in relation to that which has already been described: in such cases, it is sufficient to modify the length of the strap irons 13 and the rod 22.
- the shelf 10 is unrolled from its sheltering configuration around the rod 22 into its operational shielding position, in which the respective edges 27 are arranged along the cross members 14 and in contact with the cross members 14 themselves.
- the rings 33 are force fit onto the relative pins 31 in such a way as to constrain the shelf 10 to the frame 9.
- the shelf 10 will completely shield all the scaffolding below it, and the position of the surface 29 in relation to the channel 4 will impede any eventual infiltrations between the scaffolding 2 and the building 3 in such a way as to further increase the protection capacity of the cover 1.
- the bearing force exerted by the shelf 10 on the cover 1 is maintained within the safety limits for the scaffolding 2 by means of the passive and dynamic action of the device 11, the rings 33 of which become disengaged from the relative pins 31 once a determined value of the bearing force itself has been surpassed.
- This value is also influenced by the kind of material from which the shelf 10 is made, in that when the weight of the material is increased, such a value may also be increased.
- the rod 22 may also be provided with an automatic rolling device which is suitable for rolling the shelf 10 around the rod 22 itself in such a way that it may be controlled by an operator in order to recover the shelf 10, or in such a way that it is not controlled, or rather whenever the shelf 10 is completely detached from the cross members 14 due to the dynamic action of air currents or wind.
- an automatic rolling device which is suitable for rolling the shelf 10 around the rod 22 itself in such a way that it may be controlled by an operator in order to recover the shelf 10, or in such a way that it is not controlled, or rather whenever the shelf 10 is completely detached from the cross members 14 due to the dynamic action of air currents or wind.
- FIGURE 4 refers to a cover 1' which is similar to the cover 1, from which the cover 1' differs due to the fact that the inclined covering shelf 10 is not made by means of a continuous sheet of waterproof material, but comprises a number of tapes 40 made of waterproof material.
- each tape 40 presents a respective longitudinal sheltered edge 42 which is constrained to the cross members 14 in correspondence with the relative edges 41, and a respective exposed edge 43, which is superimposed on the edge 42 of the adjacent tape 40 which is nearest to the ridge 30, and is constrained, in such a way that it may be disengaged, to the cross members 14 themselves in correspondence to the relative edges 41 themselves.
- each pin 31 presents an upper portion 44 which is defined as has already been described and which is connected to the edge 43 together with the upper portion 44 of the corresponding pin 31 of the opposite cross member 14 in order to free the edge 43 itself, and a lower portion 45 which is connected to the edge 42 together with the lower portion of the corresponding pin 31 of the opposite cross member 14 in order to block the edge 43 itself.
- the lower portion 45 comprises an annular flange (which is not illustrated), which is integral with and transverse to the body 34, and which is arranged opposite the edge 43 in relation to the cross member 14 in order to block the edge 43 itself onto the cross member 14 itself.
- FIGURE 5 refers to a cover 1 " which is similar to the cover 1, from which the cover 1" differs due to the fact that the frame 9 comprises a further strap iron 13a, which is integral with and transverse to the cross members 14, and which is arranged in correspondence with the opposite end of the cross members 14 themselves in relation to the ridge 30.
- the dynamic connecting device 11 is still interposed between the frame 9 and the shelf 10, but it is shared by only one outlet edge 50 of the shelf 10 and by the strap iron 13a.
- FIGURE 6 refers to a cover 1"' which is similar to the cover 1, 1' and 1'', from which it differs due to the fact that the inclined shelf 10 is produced by means of three tapes 40''' which are made of waterproof material, each of which presents a longitudinal shielded edge 42''' which is anchored in removable fashion to a respective strap iron 13a "', and a longitudinal exposed edge 43''' which is superimposed on the edge 42''', and which is anchored, in such a way that it may be uncoupled, to the same strap iron 13a by means of the interposition of the dynamic connecting device 11 in the configuration described for the cover 1'', or rather which is produced by means of a number of pins 31 which are arranged one after the other along each strap iron 13a "'.
- Each pin 31 blocks the edge 42 "' of a tape 40''' to a strap iron 13a''', and permits the safety hooking to the same strap iron 13a''' of the edge 43''' of the adjacent tape 40 "'.
- the elements 19 are no longer tubular elements, but are produced by means of linear outlines and, furthermore, the elbow 25 disappears in order to be replaced by a more curved outline of the tape 40"' which is positioned therein, and, as is better illustrated in FIGURE 7, each upright 21, each element 26 and, above all, the terminal end portion 24 of each cross member 14 are replaced by a terminal end portion 24"' which is of a curved shape, and which is coupled to the relative cross member 14 in such a way that it may be uncoupled.

Description
- The present invention relates to a cover for scaffolding.
- In the construction field, scaffolding is assembled on the ground in front of a building which is undergoing restructuring or other kinds of work and either connects a series of linear tubular metallic sections to each other or a number of prefabricated frames, which are anchored to the building itself in such a way as to create a complex structure on several working levels which extend from the ground to at least a top of the building.
- In scaffolding of the type which has just been described above, the cover of the tubular scaffolding itself is arranged substantially in correspondence with the top of the building, and is generally defined by the last working level, which functions as a cover. This kind of cover, however, presents some disadvantages which, briefly, may be summed up in its inadequate capacity to provide protection from atmospheric agents, above all rainfall, and its inadequate capacity to provide drainage of the rainfall itself and, finally, considering that usually this last working level is normally in an exposed position in relation to an outline of the building, in the sail effect that such a last working level can exercise on the entire scaffolding above all when air currents, even of moderate intensity, occur.
- The aim of the present invention is to produce a cover for scaffolding, which will be able to provide effective protection from atmospheric agents such as rainfall for the tubular scaffolding beneath it and which will also be able to provide drainage and will, above all, guarantee the static and dynamic safety of the relative tubular scaffolding even when air currents of considerable intensity occur.
- According to the present invention a cover for scaffolding will be produced which is arranged in an overhanging position on a building which is undergoing construction work and presenting an upper peripheral edge, the cover being characterised by the fact that it comprises a support frame which may be coupled to a top of the tubular scaffolding itself, and an inclined covering shelf, which is connected in such a way that it may be selectively disengaged from the said frame, which extends starting from at least the upper peripheral edge into space and at least beyond the tubular scaffolding.

- With reference to FIGURE 1, the
number 1 refers to a cover in its entirety forscaffolding 2. - The
scaffolding 2 is frontally anchored to abuilding 3, which is undergoing construction work, and presents an upper peripheral edge which is defined, as in the example illustrated, by a gutter channel. Thescaffolding 2 comprises a number ofvertical piers 5, which are placed at regular intervals with equal modular spans, usually equal to 1.8 metres, and they are connected to each other by means of horizontal bracedstringers 6 in order to support a number ofworking levels 7 which are arranged at substantially regular intervals one from the other. Thepiers 5 present respective base portions (which are not illustrated) which are connected to the ground by means of pins or strips, and respectivetop portions 8 which are connected to thecover 1, and which are constrained to thecover 1 itself by means ofjoints 8a of a well-known type. - The
cover 1 comprises asupport frame 9 which is mounted on and constrained to theportions 8, and aninclined covering shelf 10, which is connected in such a way that it may be selectively disengaged from theframe 9, and which extends starting from at least thechannel 4 into space and at least beyond thescaffolding 2. - Finally, the
cover 1 comprises adynamic connecting device 11, which is interposed between theframe 9 and theshelf 10 themselves in order to connect theframe 9 and theshelf 10 to each other in such a way that they may be dynamically disengaged from each other. - According to the illustration which is shown in FIGURE 3, the
frame 9 comprises twolateral walls 12 which are arranged at a distance one from the other which is equal to the above-mentioned modular span, and a number of connectingstrap irons 13, which connect the twowalls 12 and which are transverse to the twowalls 12 themselves. - The
walls 12 are produced by means of linear elements which are connected to each other, and each comprises anupper cross member 14 which is connected to thecross member 14 of theother wall 12 by means of thestrap irons 13, and two lineartubular base elements piers 5, and of which theelement 15 presents a length which is greater than a length of theelement 16, and is arranged directly facing thebuilding 3. Furthermore, eachwall 12 comprises a respectivelower cross member 17, which is arranged transverse to therelative elements relative elements engaging portion 18 for mounting thecover 1 onto thescaffolding 2 and anchoring thecover 1 by means of thejoints 8a. - Finally, each
wall 12 comprises an intermediate lineartubular element 19, which is interposed in an intermediate position between therelative elements elements cross members - The different lengths of the
elements walls 12 an external perimeter shape which is substantially trapezoid, and impose on the relative cross member 14 a determined inclination into space, or rather opposite thebuilding 3, and in relation to therelative cross member 17. - Furthermore, the
frame 9 comprises a projectingportion 20, which is firmly connected to theelements 15 in order to extend opposite theelements 16 in relation to theelements 15 themselves in such a way as to be arranged at least beyond thechannel 4, and comprising twotubular uprights 21 which are parallel to thecross members 14, and atubular support rod 22 which is transverse to theuprights 21 and which is integral with atop edge 23 of theshelf 10. Theuprights 21 are engaged on one side by theelements 15 and on the opposite side by therod 22, which is in turn connected to aterminal end portion 24 of each of thecross members 14. In particular, eachportion 24 extends in such a way as to project beyond therelative element 15, and presents arespective elbow 25, which makes therelative cross member 14 and also theshelf 10 curve towards therod 22. - Finally, the
portion 20 comprises, for each upright 21, a reinforcingelement 26 which is arranged along the relative upright 21 transverse to the upright 21 itself, and integral with both the latter and with therelative portion 24. - The
inclined covering shelf 10 is produced by means of a continuous sheet of waterproof material, and is suitable for being rolled up into a sheltering configuration around therod 22, as it is also suitable for being arranged in an operational shielding position, with the respectivelateral edges 27 along thecross members 14 and in contact with thecross members 14 themselves and constrained thereto by thedevice 11. - The
shelf 10 comprises amain surface 28 which extends into space in order to cover thescaffolding 2 from above, a secondaryinclined surface 29 opposite thesurface 28 and which extends beyond thechannel 4, and aseparating ridge 30 between the twosurfaces elbows 25, which are arranged substantially in a vertical position on thechannel 4 permitting theshelf 10 itself to cover and shield completely thescaffolding 2 from bad weather. In particular, the double surface configuration of theshelf 10, with thesurface 28 being of a greater extension in comparison with thesurface 29, not only permits the protection of thescaffolding 2 from atmospheric precipitations, but also permits the drainage of such precipitations both towards thechannel 4 and towards the outside of thescaffolding 2 itself thus avoiding the necessity to interrupt the construction work in progress. - When air currents occur which effect the
shelf 10, at least thesurface 28 tends to exert a bearing force on theentire cover 1, and such force may be conflicted up until a certain safety value both by the weight of thecover 1 itself, as well as by thejoints 8a. Once this safety value is surpassed, or rather when a value of the bearing force on theshelf 10 is surpassed, the dynamic connecting device provides for disengaging theshelf 10 from thecross members 14. - The
device 11 is shared by the twowalls 12 and by theshelf 10, and, as is better illustrated in FIGURE 2, it comprises, for eachcross member 14, a number ofpins 31 which are provided withrespective blocking heads 32, and, for eachedge 27 of theshelf 10, aceding ring 33 which is engaged to arelative pin 31 in such a way that it may be disengaged from it. In particular, the ceding capacity of therings 33 is determined by the elasticity of the material from which therings 33 themselves are made, or by a geometrical conformation of therings 33 themselves, in relation to therelative heads 32. For example, eachring 33 together with therelative head 32 may be configured as a common, well-known type of pressure fastener. In any case, however, the ceding capacity of therings 33 determines the maximum bearing force which may be supported by theshelf 10 before it becomes detached from thecross members 14 remaining hooked to theframe 9 only along its owntop edge 23 in correspondence with therod 22. - Each
pin 31 is mounted along thecross member 14 transverse to thecross member 14 itself, and comprises atubular body 34 which is mounted in arespective passing hole 35 which is obtained through thecross member 14, and a blockingscrew 36 which is arranged on an opposite end of thebody 34 in relation to that which corresponds to therelative head 32 in order to axially block thebody 34 itself in relation to therelative hole 35. - When in use, the
cover 1 is mounted onto thescaffolding 2 in such a way that, as has already been described, thesecondary surface 29 extends beyond thechannel 4 of thebuilding 3, and themain surface 28 presents its own overhang into space, or rather towards the external part of thescaffolding 2 itself. The equality of the distance of thewalls 12 from thecover 1 and the span of the intervals of thescaffolding 2 is, as aforementioned, a modular measurement in the scaffolding field, and it renders the operations of mounting and anchoring much simpler and faster. Nonetheless, in the case of particular applications, the distance between the twowalls 12 may also be of a different measurement in relation to that which has already been described: in such cases, it is sufficient to modify the length of thestrap irons 13 and therod 22. - Once the
cover 1 has been anchored to thescaffolding 2 by means of thejoints 8a, theshelf 10 is unrolled from its sheltering configuration around therod 22 into its operational shielding position, in which therespective edges 27 are arranged along thecross members 14 and in contact with thecross members 14 themselves. During the unrolling operation, therings 33 are force fit onto therelative pins 31 in such a way as to constrain theshelf 10 to theframe 9. - In the case of bad weather, the
shelf 10 will completely shield all the scaffolding below it, and the position of thesurface 29 in relation to thechannel 4 will impede any eventual infiltrations between thescaffolding 2 and thebuilding 3 in such a way as to further increase the protection capacity of thecover 1. - Instead, in the case of the occurrence of air currents or wind, the bearing force exerted by the
shelf 10 on thecover 1 is maintained within the safety limits for thescaffolding 2 by means of the passive and dynamic action of thedevice 11, therings 33 of which become disengaged from therelative pins 31 once a determined value of the bearing force itself has been surpassed. This value is also influenced by the kind of material from which theshelf 10 is made, in that when the weight of the material is increased, such a value may also be increased. - According to a form of embodiment which is not illustrated but which is easily understandable from what has been described above, the
rod 22 may also be provided with an automatic rolling device which is suitable for rolling theshelf 10 around therod 22 itself in such a way that it may be controlled by an operator in order to recover theshelf 10, or in such a way that it is not controlled, or rather whenever theshelf 10 is completely detached from thecross members 14 due to the dynamic action of air currents or wind. - The form of embodiment which is illustrated in FIGURE 4 refers to a cover 1' which is similar to the
cover 1, from which the cover 1' differs due to the fact that theinclined covering shelf 10 is not made by means of a continuous sheet of waterproof material, but comprises a number oftapes 40 made of waterproof material. - The
tapes 40 are arranged parallel in relation to each other and in series with the respective lowerlateral edges 41 which rest on the twocross members 14. Furthermore, eachtape 40 presents a respective longitudinal shelterededge 42 which is constrained to thecross members 14 in correspondence with therelative edges 41, and a respective exposededge 43, which is superimposed on theedge 42 of theadjacent tape 40 which is nearest to theridge 30, and is constrained, in such a way that it may be disengaged, to thecross members 14 themselves in correspondence to therelative edges 41 themselves. - In particular, in this application of the cover 1', each
pin 31 presents anupper portion 44 which is defined as has already been described and which is connected to theedge 43 together with theupper portion 44 of thecorresponding pin 31 of theopposite cross member 14 in order to free theedge 43 itself, and alower portion 45 which is connected to theedge 42 together with the lower portion of thecorresponding pin 31 of theopposite cross member 14 in order to block theedge 43 itself. Thelower portion 45 comprises an annular flange (which is not illustrated), which is integral with and transverse to thebody 34, and which is arranged opposite theedge 43 in relation to thecross member 14 in order to block theedge 43 itself onto thecross member 14 itself. - In this way, in the case of the activation of the cover 1', or rather in the case of an excessive bearing force on the
tapes 40, theedges 43 become disengaged from thecross members 14, and therelative tapes 40 can freely unfold, thus reducing the bearing force on theentire shelf 10 to within acceptable safety values. - The form of embodiment which is illustrated in FIGURE 5 refers to a
cover 1 " which is similar to thecover 1, from which thecover 1" differs due to the fact that theframe 9 comprises afurther strap iron 13a, which is integral with and transverse to thecross members 14, and which is arranged in correspondence with the opposite end of thecross members 14 themselves in relation to theridge 30. - Furthermore, in the case of the
cover 1", the dynamic connectingdevice 11 is still interposed between theframe 9 and theshelf 10, but it is shared by only oneoutlet edge 50 of theshelf 10 and by thestrap iron 13a. - The form of embodiment which is illustrated in FIGURE 6 refers to a
cover 1"' which is similar to thecover 1, 1' and 1'', from which it differs due to the fact that theinclined shelf 10 is produced by means of three tapes 40''' which are made of waterproof material, each of which presents a longitudinal shielded edge 42''' which is anchored in removable fashion to arespective strap iron 13a "', and a longitudinal exposed edge 43''' which is superimposed on the edge 42''', and which is anchored, in such a way that it may be uncoupled, to thesame strap iron 13a by means of the interposition of the dynamic connectingdevice 11 in the configuration described for the cover 1'', or rather which is produced by means of a number ofpins 31 which are arranged one after the other along eachstrap iron 13a "'. - Each
pin 31 blocks theedge 42 "' of a tape 40''' to astrap iron 13a''', and permits the safety hooking to thesame strap iron 13a''' of the edge 43''' of theadjacent tape 40 "'. - In the form of embodiment which concerns the cover 1''', the
elements 19 are no longer tubular elements, but are produced by means of linear outlines and, furthermore, theelbow 25 disappears in order to be replaced by a more curved outline of thetape 40"' which is positioned therein, and, as is better illustrated in FIGURE 7, each upright 21, eachelement 26 and, above all, theterminal end portion 24 of eachcross member 14 are replaced by aterminal end portion 24"' which is of a curved shape, and which is coupled to therelative cross member 14 in such a way that it may be uncoupled. - Furthermore, the two terminal portions 24''' are connected to each other by means of a
strap iron 13a in order to block afirst tape 40a''' of the three tapes 40''', the relative longitudinal exposed edge 43''' of which is superimposed on asecond tape 40b "' of the three tapes 40''' and is blocked onto thestrap iron 13a'''. Athird tape 40c''' of the three tapes 40''' presents, in its turn, a relative edge 42''' which is inserted in fixed fashion between thestrap iron 13a "' and the edge 43''' of thesecond tape 40b "', and the relative edge 43''' is coupled to thestrap iron 13a as in the example which is illustrated n FIGURE 5. - The two
terminal portions 24 "' and therelative strap iron 13a''' define a projecting portion 20''', which may be constrained to the rest of theframe 9, thus permitting the creation of amodular cover 1 "', which is a further alternative form of embodiment of the covers which have been described above, and which permits, as is better illustrated in FIGURES 8 and 9, the construction of aroof 100 with two surfaces, which completely covers aroof 101 of thebuilding 3, and which permits the combination between themselves in modular fashion of twoscaffoldings 2 which are arranged opposite thebuilding 3 itself in such as way as to ensure for eachmodular cover 1"' the same characteristics of static and dynamic sealing even in the case that air currents occur. - In the case of the
roof 100, themodular covers 1"" are supported by a number ofinclined uprights 102 for each surface of theroof 100 itself, and they are arranged in correspondence with the ridge of theroof 100 itself and are connected to each other by means of respective connectingportions 24"" which are substantially identical to the portions 24'''. - In conclusion, and with specific reference to the
pins 44, it is possible, in some applications, to produce therings 33 in magnetic or magnetised material and to replace theheads 32 with plates made of ferrous-magnetic material, or replace therings 33 and theheads 32 with respective pairs of strips of Velcro. - It is intended that the present invention should not be limited to the forms of embodiment herein described and illustrated, which are to be considered as examples of forms of embodiment of a cover for scaffolding, and which might instead be subject to further modifications relating to the shape and disposition of the parts and to details pertaining to construction and assembly.
