[0001] The present invention relates to a balcony or the like, which can be attached in
a simple manner to an object that can be any structure, such as a building, a vessel,
etc. By way of example, the following description deals with a balcony fastenable
to a vessel but, as pointed out above, the invention is not limited solely to such
an application.
[0002] Vessels are currently outfitted more and more often with balconies or other such
outboard structures. Balconies are mounted on support girders jutting beyond the hull
of a vessel, said girders being welded to the hull. In order to ensure sufficient
stability and strength, the girders are located in coincidence with intra-hull bracing
ribs, i.e. the balcony-supporting girders constitute a sort of "extension" to the
internal bracing ribs. Retrofitting support girders by welding becomes more inconvenient
as the locations of internal bracing ribs are not clearly apparent from outside the
hull. In addition, the sizing of a balcony is restricted by the spacing between bracing
ribs.
[0003] It is an object of the present invention to simplify the mounting of a balcony to
the side of a ship.
[0004] According to the invention, this is accomplished in such a way that the structure-mounted
balcony comprises a prefabricated balcony unit, in which the end face towards a structure
is provided with fastening profiles and the structure wall is at desired locations
fitted with clamping elements complementary to said fastening profiles for fastening
the prefabricated unit to the structure.
[0005] With a system of the invention, the prefabricated balcony unit is simply fastenable
to a desired location, the mounting is not dependent on an internal bracing structure,
nor does the spacing of internal braces restrict the sizing of a balcony.
[0006] Other characterizing features of the invention will be apparent from the appended
dependent claims.
[0007] The invention will now be described in more detail with reference to the accompanying
drawings, in which
- Fig. 1
- shows a prior known solution, and
- Fig. 2
- shows a preferred embodiment of the invention mountable on a vessel.
[0008] In the prior known traditional solution shown in fig. 1, to a ship's side 1 in coincidence
with an internal bracing rib 2 is welded an outward tapering support girder 10, such
that the support girder 10 provides for the internal beam 2 an extension jutting out
of the ship's side 1.
[0009] In order to ensure sufficient stability and strength, the support girders or ribs
2 must be welded to the outer surface of the ship's side 1 in coincidence with the
internal beam 2. In practice, the determination of this spot complicates mounting.
In addition, the distance between the bracing ribs 2 and, hence the sizing of a balcony,
are dependent on the spacing of the bracing ribs.
[0010] In a solution of the invention as shown in fig. 2, no outboard extending support
girders are welded to a ship's side 1 in coincidence with a bracing rib 2. Instead,
to the ship's side are welded steel profiles 3 and 4, which are spaced from each other
and comprise U-section channels and are positioned in such a way that the upper profile
opens upwards and the lower one 4 opens downwards. These steel profiles are intended
to have a ready-to-use balcony unit 10 secured thereto.
[0011] The balcony unit 10 is constituted by support girders 8 tapering towards the outer
end. The number of girders 8 can be two or more, as necessary. The girder is structurally
light, e.g. provided with holes, trussed, a laminate or the like, and the manufacturing
material can be anything suitable for the purpose, e.g. steel, aluminium, light metal,
wood, fiber glass or plastics. To the support girder's 8 outer end is secured, with
screws or the like, an end railing 9, an end wall, or the like. The support girder's
8 lengthwise side will be fitted with side railings, side walls, or partitions, as
the case may be. Rainwater drains are also incorporated in the support girder and/or
between such girders.
[0012] The prefabricated balcony unit 10 may consist of e.g. honeycomb panel and its surface
may additionally be covered with a honeycomb-structured balcony slab or the like.
The girder 8 may have its bottom face provided with a cover panel for thereby concealing
fixtures and equipment incorporated inside the girder, e.g. prefitted water pipes,
electric wires, and necessary accessories.
[0013] To the support girder's 8 wider end face, which lies towards a ship's side, is secured,
with bolts or the like, a fastening profile 5 which is substantially consistent with
the size of the girder. The fastening profile 5 has its upper edge designed as a downward-directed
claw-shaped bearing member 6 to fit in the channel of the upper steel profile 3.
[0014] The fastening profile 5 has its bottom edge provided with a clamping bar 7, attachable
with screws or similar fastening elements and including an upward-rising claw-shaped
member.
[0015] When the balcony unit 10 is lifted to rest upon the upper steel profile 3 and the
bearing member 6, the clamping bar 7 is attached to the unit fastening profile 5 and
simultaneously behind the lower profile 4 for securing the unit 10 in place. Attachment
of the clamping bar 7 is effected simply by means of a few screws or other similar
fastening elements. Thus, the balcony unit 10 can be secured and mounted at a desired
location in a simple manner. The installation work is simple.
[0016] The bearing member 6, as well as the clamping bar 7, may have lengths which are consistent
with the width of an entire prefabricated balcony unit or may consist of several elements
the same way as the steel profiles 3 and 4.
[0017] In a preferred embodiment, the fastening profile 5 may be a separate element which
is attached to a balcony unit. In such a solution, the profile can be sized and shaped
to always satisfy the special demands of a structure which the unit is intended for.
If, for example, the mutual distance between the steel profiles 3, 4 in various parts
of the structure cannot be maintained the same, then just the fastening profile 5
is re-positioned and no changes are required to the balcony unit. It is also possible
to use the same balcony unit for various applications by just modifying the fastening
profile appropriately.
[0018] The prefabricated balcony unit 10 can be a completely ready-to-use balcony with all
its accessories and wiring systems, but of course it can also be a semi-finished product,
as necessary.
[0019] Benefits of this prefabricated balcony over conventional technology include e.g.
as follows:
- A prefabricated unit can be manufactured and finished entirely indoors. A traditional
method of building is at the mercy of weather.
- Installation of a prefabricated unit is fast, thus relaxing the schedule of other
operations.
- Installation of a prefabricated unit requires no scaffolding or guard rails consistent
with industrial safety standards, since the unit has its own railing already in place.
- The length of a prefabricated unit is not dependent on the rib spacing of a ship,
since the "hooked profile" provides support along the entire side.
- Precise welding of separate consoles has been difficult. The hooked solution eliminates
tolerance problems.
- No fastening holes are needed in ship structures.
- If the bottom part of a prefabricated unit is fitted with a covering metal sheet,
e.g. rainwater drains and electric wires can be "hidden" inside the prefabricated
unit as early as in manufacturing.
