Description
TEMPORARY BUILDING EDGE SAFETY SCREEN SUPPORT
TECHNICAL FIELD
[0001] The present invention relates to safety devices and, more particularly, although not exclusively, to safety devices for buildings under construction.
BACKGROUND
[0002] All Building sites require safe working areas at or near exposed areas where there is any chance of a person and/or material falling and/or dropping from an elevated level. A physical edge protection system is one way of decreasing any such likelihood of this type of event taking place. Current systems do provide edge protection; however, they have their limitations. These limitations include
1. Prohibits other external works being undertaken outside of the edge protection system.
2. Are heavy and cumbersome to manhandle increasing likelihood of manual handling injuries.
3. Personal edge protection system is complete however materials protections are not due to design issues in the system.
4. Materials edge protection is complete however personal edge protection is decreased due to design issues in the system.
5. Inflexibility of current systems to cater for the increasingly various and unusually shaped building architecture.
[0003] Many known systems provide for so-called catch nets which extend beyond the edge of a building such as for example are disclosed in US4838382A, US2006009096A1 and US20060214150A1. Vertically disposed safety nets are also known as for example disclosed in CN205369964U in which a safety screen is supported by structures retained between floors by friction.
[0004] It is an object of the present invention to address or at least ameliorate some of the above disadvantages.
NOTES
[0005] The term “comprising” (and grammatical variations thereof) is used in this specification in the inclusive sense of “having” or “including”, and not in the exclusive sense of “consisting only of’.
[0006] The above discussion of the prior art in the Background of the invention, is not an admission that any information discussed therein is citable prior art or part of the common general knowledge of persons skilled in the art in any country.

DESCRIPTION OF EMBODIMENTS
First Preferred Embodiment
[00069] The present invention provides supports for a vertical safety net proximate the outer edges of floors of a multistory building under construction; the supports providing for a safety net extending between the adjacent floors of the building and along the length requiring protection. [00070] Supports 10 for supporting a safety net, one of which is shown in figure 1, comprise telescoping posts 12 retained between lower bracket 14 and upper bracket 16; the brackets bolted respectively to the surface of the floor 18 at which the net is to be installed and the underside of the floor 20 above.
[00071] With reference to figures 2 and 3, upper bracket 16 is in the form of a section of angle iron (or other suitable metal), the horizontal flange 22 of which is provided with a pair of apertures 24 for receiving securing bolts (not shown) while the vertical flange 26 is provided with a bolt receiving opening 28. The opening 28 is shaped so that a bolt 30 passing through the upper end of the telescoping post 12 may be inserted through the slot part 32 of the opening 28 to then nest in the hook portion 34. Preferably, the bolt 30 is permanently installed in the upper end of the telescoping support post 12 by securing nuts 36 and 38, leaving a space between outer securing nut 38 and the head 40 of the bolt approximately equal to the thickness of the vertical flange 26 allowing for a sliding fit of the bolt into the hook portion 34.
[00072] Turning now to figure 4, the lower bracket 14 also comprises a section of metal angle with the lower horizontal flange 42 provided with apertures 44 for bolting the bracket to a supporting floor. The vertical flange 46 is provided with a pair of apertures 48 to allow a lower end of the telescoping support post 12 to be secured to the bracket.
[00073] As can be seen in figure 1 and also in figure 5, the telescoping support post 12 is comprised of a lower section 12A and an upper section 12B, of rectangular hollow section (RHS) with the two sections sized so as to allow the upper section 12B to slide into the lower section 12A. [00074] The upper end of the lower section 12A is provided with a collar 50 with at least one threaded aperture 52 to receive a locking bolt 54 which may be driven through the threaded aperture 52 and a coincident aperture through the RHS of the lower section 12A, to urge against the RHS of the upper section 12B. By this means the upper and lower sections of the posts are locked together to suit the distance between the adjacent floors 18 and 20. Preferably, the locking bolt 54 is provided with a handle 56 so that the two sections of the support post may be secured without the need for tools.
[00075] Provided at intervals along the lower section 12A and upper section 12B of the telescoping support post 12, are safety net attachment elements 58. Preferably these may be in the form of carabiners welded to the RHS sections of the support post allowing for rapid attachment and removal of the safety net.
In this embodiment of the invention, at least two or a required number of support posts 10 are installed between the adjacent floors of a building under construction by firstly installing the upper and lower brackets by bolts driven into the concrete of the floors. The bolt 30 at the upper end of the upper section 12B of each telescoping support post 12 is then nested in the hook portion of its upper bracket and the lower section 12A of the support post allowed to slide to the lower bracket where it is secured to the bracket. The two sections 12A and 12B are then locked together by the tightening of the bolt 54. The safety net (not shown) can then be secured to the carabiners 58.
Second Preferred Embodiment
[00076] In a second preferred embodiment of the invention, the upper and lower brackets may be permanently affixed to the respective upper end of the upper section 12B and the lower end of the lower section 12A of the telescoping support post 12. The upper bracket is secured to the underside of the floor above by means of previously installed securing bolts. Similarly, the lower bracket is secured to bolts driven into the floor. In this arrangement the upper and lower sections of the support post are loosely assembled and the post positioned vertically between the upper and lower brackets and the telescoping sections locked together.
Third Preferred Embodiment
[00077] In this further preferred embodiment, support posts are prepared to a length appropriate to the separation between adjacent floors. In this arrangement the support post RHS is of one length somewhat less than the separation between floors.
[00078] As in the embodiments described above, the support post is secured between upper and lower brackets, but in this embodiment the hook portion of the opening in the upper bracket is in the form of a slot with parallel sides. The upper end of the support post is again provided with a permanently installed bolt which is slidingly located in the slot. The lower end of the support post is then secured to the lower bracket.
Fourth Preferred Embodiment
[00079] In this embodiment, the safety screen 200 is combined with an independent modular guard rail system 100 as shown in figure 6 in which horizontal guard rails form a balustrade designed primarily to prevent personnel from falling. Features of the system include:
1. 1. Imetre high safety balustrade.
2. Primarily designed and engineered for the prevention of human falling from heights safety
3. Clamp systems on the posts, which secure the horizontal safety rails to the posts.
4. Rails can be adjusted to suit various span lengths.
5. Rails can be curved so that they can follow any edge radius profile
6. Bottom Rail has an integrated rubber strip to help prevent materials from falling over the perimeter edge/void.
7. A metal mesh screen with solid strip above floor level to assist debris and other items from penetrating the fence and falling over the perimeter edge/void.
[00080] With reference to figures 7 to 10, the guard rail system 100 includes vertical posts 110 of RHS supported by angle brackets 112 secured to the floor at which the guard rails are to be installed. The vertical posts 110 are provided with bolt hole at the levels of, preferably, three guard rails also of RHS; bottom rail 114, mid rail 116 and top rail 118, with the bottom rail 114 secured to the post 110 by a first bottom clamping bracket 120 and the mid and top rails each secured to the post by second rail clamping brackets 122. As shown in figures 7 and 8, the bottom rails 114 incorporate an integrated rubber flap 124 extending between the bottom rail and the floor on which the guard rail system is installed. It should be noted that each of the clamping brackets provides for clamping of a single or overlapping, side by side sections of rail.
[00081] Because of the integral rubber flap 124 of the bottom rails 114, the first bottom rail clamping bracket 120 is of a different configuration to the second clamping rail clamping bracket 122. As seen in figures 7 and 8, the bottom rail clamping bracket 120 may be formed of a section of RHS of a depth sufficient to allow one or a pair of bottom rails to pass through and a rail clamp tensioning bolt 126 for securing the clamping bracket to the post. Preferably, the integral rubber flap 124 is secured to one face of the bottom rail, and it may be noted from figures 7 and 8 that, in the installation of overlapping bottom rails, the faces of the rail from which the flaps depend are turned to face one another.
[00082] Turning now to figures 11 to 14, the second clamping brackets 122 for the mid and top rails are in two sections comprising a lower jaw 128 shown in figure 13 and an upper jaw 130 shown in figure 14. Again preferably, each of the jaws is formed of a section of RHS, cut and slotted to suit the applications. The lower jaw 128 is provided with a clamp tensioning bolt access aperture 132 and on either of its longer faces with single and double rail adjustment slots 134. Rail locating pins 136 or projections are provided along the upper edges of the lower jaw.
[00083] The upper jaw 130, again formed preferably of a section of RHS, is provided with a recess 138 with rail locking pressure points 140 allowing for one or two side by side mid or top rails, and with single and double rail adjustment slots 142. One end of the upper jaw 130 is provided with an extension 144 and in that extension a rail clamp tensioning bolt aperture 146.
