The present invention relates to a method and device for securing a balcony to a façade of a building, and to a balcony including said device.
Balconies are often specified in the plans drawn up by architects for new or existing buildings, as a way of increasing the liveable space. These balconies may be decorative, but in many cases they must be structurally secure and capable of supporting the load of several people as well as furniture (balustrades, panels, handrails, etc.) needed to make the balcony safe and usable.
In existing building approaches, a metalworker may attend the site to bolt “stubs” onto/into the concrete frame of a façade of a building while the basic structure of the building is being constructed. At a later stage, often after the main structure of the building, including brickwork and windows is complete, a frame for the balcony is manufactured off site from mild steel, galvanised, and transported to site. The balcony frame is then lifted by crane and held aloft adjacent to the stubs whilst the frame is aligned with the stubs and then bolted onto them by works working underneath or adjacent to the loose balcony.
There are a number of problems with this process.
Firstly, there is a safety risk for the workers who are aligning the balcony and bolting it in place. These workers normally have to either work from an elevated platform (a “cherry picker”), or on a scaffold tower from the ground level or the floor below. There is inevitably a risk of falling associated with working at height. Furthermore, there are risks associated with the manual handling of trying to push the balcony into position, and a risk of trapping hands and figures when trying to get the balcony into position and bolted on. These risks are increase because of the length of time it takes to fix a balcony using this method, as discussed below.
Secondly, it takes a substantial amount of time to install each balcony using this method. The crane has to stay in position supporting the balcony in mid-air while the workers align and bolt the balcony firmly in place. The workers then have to move all their access equipment and tools up to the next floor or balcony location before they can start the installing the next. As a result, the delivery driver also has to stay on site whilst each of the balconies is lifted into position one at a time.
It is also known to provide ‘slide-on’ balconies, for example as disclosed in GB 2507365 A. Where arms project from the building and the balcony is slid onto them and rests upon them. This allows for operatives to install from inside the building using a guarded door/window opening to access the balcony and guide it into place. However, this method is not usable if the projecting arms clash with façade access equipment, or if there are obstructions such as cladding features which prevent the balcony from being slid into place along the arms.
Accordingly, and generally, the invention is concerned with providing an activatable balcony fixing including a shaft and a method of using the same, which can provide tapering engagement between a fixing located on both a balcony and a projection of a building, thereby guiding the balcony into a secure position relative thereto.
A first aspect of the present invention provides a method of fixing a balcony to a façade of a building using an activatable balcony fixing including a shaft, the method having the steps of:
The term ‘tapering engagement’ is used herein to define that the one or more of the shaft and the socket in the projection (also referred to herein as ‘the projection socket’) comprises a tapered portion. For example, the shaft may be a tapered shaft (i.e. at least a portion of the shaft may reduce in thickness or diameter along a length of the shaft). Alternatively or additionally, the projection socket may be tapered (i.e. at least a portion of the socket may reduce in diameter along a depth of the socket). In some arrangements, both the shaft and the socket in the projection may comprise a tapered portion.
By providing this tapering engagement between the shaft and the socket, it is possible to fit a balcony to a façade of a building with less exact alignment. By the action of driving the shaft through the socket of the projection the balcony will be further aligned with the projection.
Herein, the projection of the façade may be referred to as a stub.
Optional features of the invention will now be set out. These are applicable singly or in any combination with any aspect of the invention.
The one or more further fixings may be one or more combinations of nuts and bolts, which fix the balcony to the façade. The balcony may have a support beam, which extends in a direction generally aligned with a direction in which the projection projects. The further fixings may fix the support beam to the projection or stub. The stub may be fixed to one or more threaded metal rods embedded in concrete forming the façade. The activatable balcony fixing may be provided on an upper surface of the balcony, i.e. on a surface distalmost from the ground. The activatable balcony fixing may be referred to as a cone.
The balcony may have a surface which is bevelled at an angle greater than 0°. This surface may be that which is closest to the projection when the balcony is aligned with the projection. The surface may be bevelled at an angle of no more than 2°, in some examples it may be bevelled at an angle of 1.6°. This bevelled surface allows for a degree of tolerance as the activatable balcony fixing is activated. The stub or projection may extend no more than 1 metre from the façade, it may extend no more 0.5 metres, or no more than 0.2 metres from the façade.
The activatable balcony fixing may be fixed to the balcony via a clamp or other removable means. The activatable balcony fixing may be fixed to the support beam of the balcony.
The activatable balcony fixing may be remotely activatable. By remotely activatable, it may be meant that an activation mechanism of the activatable balcony is not located in or immediately adjacent to the tapered shaft. For example, the activation mechanism may be located at the end of a cable, or may be wirelessly connected to a user input device.
The shaft may be driven through the socket via an actuator. The actuator may be powered by either electricity or hydraulics or pneumatics. In some arrangements, the shaft may be connected to a mechanism which is operable via a lever in order to move the shaft with respect to the balcony.
The method may include a further step, after securing the balcony to the façade through the one or more further fixing, of removing the activatable balcony fixing from the balcony. As a result, it is possible for a single activatable balcony fixing to be used in the installation of plural balconies. Alternatively, it may be that the activatable balcony fixing forms some part of the ultimate structure of the balcony and so remains installed therein.
The balcony may include a joining plate, to which the activatable balcony fixing is mounted, and which may be positioned so as to overlap a portion of the projection of the façade when the balcony is aligned with the projection. The joining plate may include a socket, and aligning the balcony with the projection may include aligning the socket of the joining plate with the socket of the projection, and the shaft may be driven through the socket of the joining plate and the socket of the projection. Where the joining plate includes a socket, the socket may comprise a tapered portion.
The balcony may include a second activatable balcony fixing including a shaft, which is attached to the balcony at a point distal to the first activatable balcony fixing. In such examples, aligning the balcony may include aligning the second activatable balcony fixing with a second socket of the projection or a second projection, and the method may include driving the shaft of the second activatable balcony fixing through the second socket, wherein the shaft of the second activatable balcony fixing and/or the second socket are configured so as to provide tapering engagement between the shaft of the second activatable balcony fixing (‘the second shaft’) and the second socket. As discussed above in relation to the first activatable balcony fixing, the second shaft may be a tapered shaft (i.e. at least a portion of the second shaft may reduce in thickness or diameter along a length of the shaft). Alternatively or additionally, the second socket may be tapered (i.e. at least a portion of the second socket may reduce in diameter along a depth of the socket). In some arrangements, both the second shaft and the second socket in the projection may comprise a tapered portion.
In a second aspect, the invention provides an activatable balcony fixing, suitable for securing a balcony to a façade, the fixing comprising:
The tapered shaft allows the alignment to be inexact, as by driving the shaft through the socket of the projection the balcony will be further aligned with the projection.
Optional features of the invention will be set out. These are applicable singly, or in any combination with any aspect of the invention.
The actuator may be remotely activatable. By remotely activatable, it may be meant that an activation mechanism of the activatable balcony is not located in or immediately adjacent to the tapered shaft. For example, the activation mechanism may be located at the end of a cable, or may be wirelessly connected to a user input device.
The actuator may be powered by either electricity or hydraulics or pneumatics. Alternatively, the tapered shaft may be connected to a mechanism which is operable via a lever in order to move the tapered shaft with respect to the balcony.
The mount maybe configured to releasably hold the tapered shaft and actuator to the balcony. As a result, it is possible for a single activatable balcony fixing to be used in the installation of plural balconies. Alternatively, it may be that the activatable balcony fixing forms some part of the ultimate structure of the balcony and so remains installed therein.
The balcony may include a joining plate configured, when the fixing is mounted to a balcony, to overlap a portion of the projection of the façade. The joining plate may include a socket, and the tapered shaft may be arranged so as to pass through the socket in the joining plate when securing the balcony to the façade.
In a third aspect, the invention provides a balcony configured to be secured to a façade of a building, the balcony comprising:
By providing this tapering engagement between the shaft and the socket, it is possible to fit a balcony to a façade of a building with less exact alignment. By driving the shaft through the socket of the projection the balcony will be further aligned with the projection.
Optional features of the invention will be set out. These are applicable singly, or in any combination with any aspect of the invention.
The activatable balcony fixing may be remotely activatable. By remotely activatable, it may be meant that an activation mechanism of the activatable balcony is not located in or immediately adjacent to the tapered shaft. For example, the activation mechanism may be located at the end of a cable, or may be wirelessly connected to a user input device.
The activatable balcony fixing may include an actuator, configured to drive the tapered shaft through the socket. The actuator may be powered by either electricity or hydraulics or pneumatics. In some arrangements, the tapered shaft may be connected to a mechanism which is operable via a lever in order to move the tapered shaft with respect to the balcony.
The joining plate of the balcony may include a socket, and the activatable balcony fixing may be configured to drive the shaft through the socket in the joining plate when securing the balcony to the projection of the façade. Where the joining plate includes a socket, the socket may comprise a tapered portion.
The balcony may include:
In a fourth aspect, the invention provides a kit for securing a balcony to a façade of a building, the kit comprising:
By providing this tapering engagement between the shaft and the socket, it is possible to fit a balcony to a façade of a building with less exact alignment. By driving the shaft through the socket of the projection the balcony will be further aligned with the projection.
Optional features described in relation to the balcony of the third aspect also apply in respect of the balcony forming part of the kit of the fourth aspect.
Optional features described in relation to the activatable balcony fixing of the second aspect also apply in respect of the activatable balcony fixing forming part of the kit of the fourth aspect.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which:
Aspects and embodiments of the present invention will now be discussed with reference to the accompanying figures. Further aspects and embodiments will be apparent to those skilled in the art.
The activatable balcony fixing 110 broadly comprises an actuator 104 and a tapered shaft 105. The actuator 104 is operable so as to move the tapered shaft 105 relative to the support beam 101 of the balcony. In this example, the joining plate 102 includes a socket 106 wide enough to allow the passage of the tapered shaft 105. In other examples, the joining plate 102 may not extend as far from the support beam 101 as a portion of the tapered shaft 105 which is closest to the support beam 101. The end of the support beam 101 may be bevelled, i.e. at an angle relative to the extension of the tapered shaft. This angle may be greater than 0° but less than 2°. In some examples, this angle is around 1.6°. This bevelling allows for a degree of tolerance when fixing the balcony to the façade.
