Description
This invention relates to a balustrade post and a balustrade formed using posts in accordance with this invention which are used as a safety barrier and in particular a safety barrier on building sites.
Building sites, and in particular multi-storey building sites, require personnel safety protection at the perimeter of the building. Barriers and screens are used at the edge of floor slabs as protection for personnel working on a floor slab where the external cladding of a building is yet to be installed.
One element used on floor slabs are balustrades located at or near the edge of a floor slab which comprises a plurality of posts and horizontal rails, where the posts are secured to the upper surface of the floor slab.
External cladding is often located and fixed at the edge of the floor slab. External walls or wall panels are positioned and fixed one on top of the other up the side of the building. As they are located on the side of a building, wall panels may extend only partly past the upper surface of the floor slab. Further, the wall panels may be fixed against or fixed so that they are spaced from the floor. This in turn effects the location and use of protective balustrades.
Accordingly, an alternative means of securing a post with respect to an edge of a building may be desirable particularly to allow ease of location and access to any external cladding.
For example, the building process will involve the lowering of wall panels into place on top of wall panels already in place. If the balustrade is located adjacent to a lower wall panel, then there will be some difficulty in being able to locate the next wall panel without the balustrade being in the way or requiring it to be relocated.
It is against this background that the invention has been developed.
In one aspect, there is provided a post of a balustrade assembly wherein the post comprises: a post element, a connection means on the post element for releasably securing a balustrade rail, and a foot element at the lower end of the post element, for supporting the post, the foot element having a horizontal member and a vertical member to allow the post element to be secured to either a horizontal or vertical surface.
In a further aspect, there is provided a post for a balustrade assembly wherein the post comprises: a post element, a foot element at a lower end of the post element, for supporting the post, the foot element comprising a horizontal member and a vertical member to allow the post to be secured to either a horizontal or vertical surface, and a connection means on the post element comprising a through aperture in the post element in which a horizontal balustrade rail can be located, and an aperture in the post element with a captive nut for receiving a threaded fastener from an opposing side of the post element to the vertical member, for releasably securing the balustrade rail in the through aperture.
In one form, the post element comprises a hollow steel tube.
In one form, the tube is rectangular in cross-section.
o In one form, the post comprises at least two of the connection means on the post element.
In one form, the or each through aperture comprises a rebate on one side of the post element and a flat plate extending across the rebate to form the aperture.
In one form, each of the connection means comprises at least two apertures with captive nuts, each for receiving a threaded fastener.
In one form, the foot element comprises a length of angle section comprising the horizontal member and the vertical member, where the length of the angle section is greater than the width of the post element.
In one form, there is a spacer element located between the post element and the vertical member of the foot element.
In one form, the spacer element is a length of steel tube.
In a further aspect, there is provided a post for a balustrade assembly wherein the post comprises: a post element comprising a steel hollow tube, a connection means on the post element, comprising a through aperture in the post element in which a horizontal balustrade rail can be located, and a foot element welded to a lower end of the post element, for supporting the post element, the foot element comprising length of angle comprising a horizontal member and a vertical member to allow the post to be secured to either a horizontal or vertical surface.
o In one form, the angle section comprises apertures in each of the horizontal and vertical members on either side of the post element.
In one form, the post and foot element are steel and are welded together with respect to each other.
In one form, for each of the connection means the through aperture is rectangular.
In another aspect, the post may further comprise a spacer element located between the post element and the vertical surface of the foot element so that the post element is spaced away from any o vertical surface to which the foot element is attached.
In this case, if the post is secured with respect to a vertical surface, then sufficient spacing between the post and the vertical element is ensured to allow the placement of further building elements in place without the balustrade being in the way or preventing access.
A preferred embodiment will now be described, but it should be realised that the scope of the invention is not to be confined or restricted to the precise details of these embodiments. Variations and modifications as would be apparent to the skilled addressee are considered to be within the scope of this invention. The embodiments are illustrated in the accompanying drawings in which: Figure IA shows a first embodiment of a balustrade post, Figures lB to ID show side views of a balustrade post as seen in Figure 1A, Figure 2A shows a second embodiment of a balustrade post, Figures 2B to 2D show side views of a balustrade post as seen in Figure 2A,
Figure 3 shows the use of balustrade posts and balustrade rails to form a balustrade at the edge of a building, Figure 4 shows a balustrade post as shown in Figures IA to ID attached to a preform panel adjacent a floor slab, Figure 5 shows a balustrade post as shown in Figures 2A to 2D attached to a preform panel adjacent a floor slab, Figure 6 shows a detailed view of a connection means used on the posts, Figure 7 shows a balustrade post as shown in Figures IA to ID attached to a preform panel, Figure 8 shows a balustrade post as shown in Figures 2A to 2D attached to a slab at the edge of a building, and Figure 9 shows a balustrade post as shown in Figures 2A to 2D attached to a preform panel.
Referring to Figures 1A to ID, a balustrade post 10 is shown which comprises a post element 11 manufactured from square cross-section steel tubing. At the top of the post element 11 and at a mid position spaced from the top of the post element 11, connection means 12 are provided comprising rectangular apertures 21 within the post elements 11 through which horizontal rails can be located. The apertures may be formed by cutting a rebate into one side of the post element 11 and then welding Sa flat plate across the opening. Alternatively, and as shown in Figures 1C and 6, rectangular apertures 21 are cut using high pressure fluid jets and a plate 26 is welded to the post element 11 to strengthen this section of the post element 11.
The connection means 12 are provided with apertures 22 into which captive nuts 23 (such as those sold under the trademark "Nutserts" or "Rivnuts") are located and fixed into place. Threaded fasteners 24 locate in the captive nuts 23 and bear against the balustrade rails which in this embodiment are horizontal rails 25 to thereby secure the horizontal rails 25 in place.
Plates 26 are welded to the outer surface of the post element 11 on the side opposite to the apertures 22 to strengthen the post element 11. The plate 26 assists in preventing deformation of the post element 11 about the apertures 21 when the threaded fasteners 24 are tightened against the horizontal rails 25.
The post 10 is provided with a foot element 13 which in Figures 1A to ID is a length of angle comprising a horizontal member 14 and a vertical member 15. As seen in the illustrations, the foot member 13 is wider than the post element 11 and has a series of apertures 28 located either side of the post element 11 to enable the post 10 to be either secured to a horizontal or vertical surface.
Figures 2A to 2D show an alternative embodiment to that shown in Figures 1A to ID with the difference being a spacer element 16 located between the post element 11 and the vertical member 15 of the foot element 13. The spacer element 16 spaces the post element away from the vertical member 15 to ensure that there is a space between the post element 11 and the vertical surface to which the post 10 may be secured.
As seen in Figure 3 (and Figure 8), a number of posts 10 have been secured to a floor slab 19 with horizontal rails 25 put in place. The apertures 28 in the horizontal member 14 allow each post 10 to be firmly secured to the floor slab 19 at its perimeter or outer edge of the building. This provides the required safety barrier at the edge of the floor slab 19.
However, as seen in Figure 4 (and Figures 7 and 9), if a precast wall section 18 is projecting above a floor slab 19, then the same post 10 can be secured to the vertical surface of the wall section 18 as an alternative to securing it to the floor slab 19. This provides a convenient alternative.
This balustrade (including the rails 25) remains clear of an edge of the vertical wall section 18 to which it is secured, but the nuts 23 can be fitted and tightened, and hence the rails 25 secured, from inside of the balustrade.
The importance of the spacer element 16 is illustrated in Figure 5 which shows a post 10 according to the second embodiment (Figures 2A to 2D) secured to the vertical surface of a precast wall panel 18. As can be seen in this illustration, the location of the post 10 against the vertical surface of the precast wall panel 18 could potentially cause some difficulty when a further precast wall panel 18a is lowered in place on top of a lower precast wall panel 18. In this case, the post 10 would be very close to the precast panel 18a and therefore may cause some difficulty in positioning and securing the panel 18a. In order to overcome this problem, the spacer element 16 spaces the post element 11 away from the precast wall panel and therefore provides adequate clearance for location of the further precast wall panel 18a into its position on top of the lower precast panel 18.
The embodiments as described above provide a post which is capable of being secured to both a horizontal and vertical surface and also provides a solution to the problem of spacing the post away from a vertical surface to which it may be adjacent or attached.
