[0001] The present invention relates to a method of handling and joining sectional steel
elements together to form a load-bearing beam element, preferably for interaction
with a separately-formed post footing, and a beam element made from sectional steel
elements, (see
US-A-2 697 453).
[0002] The use of standardised sectional beams of commercial-grade steel often means that
the structure in question is of overlarge dimensions and unnecessarily rigid, which
in addition to unnecessary use of material can also represent an increased hazard
where the beam is to be used in close proximity to busy roads. Prefabricated sectional
beams, moreover, take up more space than the detached sectional elements of which
they are made up, which are easier and more economic to stack, store and transport.
Prefabricated sectional beams therefore result in higher handling, storage and transport
costs than detached sectional elements, which can be stored and handled and are only
joined together to form a load bearing beam element at the place of use.
[0003] The main object of the present invention is therefore to devise a method of handling
and joining at least two sectional elements together to form a load-bearing beam element,
preferably for interaction with a separately-formed post footing. Another object of
the invention is to provide a load-bearing beam element, which can be easily dismantled
after a period of use, so that the constituent sectional elements can be individually
handled and can thus be moved efficiently to intermediate storage depots/stores for
subsequent use at a new place of use. The invention has a particular application in
the erection of screening fences and/or noise screens, but can obviously also be used
for signs etc.
[0004] This object is achieved in that the method and the beam element have the characteristics
specified in the claims.
[0005] The invention will be described below with reference to examples of embodiment shown
in the drawings attached, in which:
Fig. 1 shows a diagrammatic perspective view of the handling and joining stages of
the beam element according to the invention,
Fig. 2a-2c show a diagrammatic perspective view of the attachment of the beam element
to a post footing,
Fig. 3 shows a diagrammatic perspective view of the introduction of a combined noise
screen and screening fence into channels of two beam elements located at a specific
distance from one another.
Fig. 4 shows a diagrammatic perspective view of an alternative fitting of a combined
noise screen and screening fence to the beam element in conjunction with the arrangement
of the sleeve plate, and
Fig. 5a-5f show perspective views of various possible couplings of sectional elements
and sleeve plates.
[0006] Figure 1 shows two angle section elements 1a and 1b being inserted one inside another
to form a closed sectional beam 1. Also shown here are two sleeve plates 2a and 2b,
which are fixed to the sectional beam 1 to form the beam element A. Fixing to the
sectional beam 1 can be achieved by bolted connection or by spot welding.
[0007] Figures 2a to 2c show the assembly of the finished, closed beam element A, the post
footing 3 in figure 2a being shown set in a body 4 in the ground. The beam element
A is pushed down onto the post footing 3 and assumes the final position as shown in
figure 2c. The screening fence and/or noise screen 5 is inserted into the beam elements
A
1, A
2 from the top, these elements having already been fitted on the post footings, as
shown in figure 3. If thought suitable, it is obviously possible to first fit the
fence or the screening 5 to one beam element A
1, which has already been fitted to the post footing in the body 4
1 and then to push the fence or the screen 5 into the beam element A
2, which is held straight over the second post footing, before then pushing the beam
element A
2 down over the post footing in the body 4
2 in the ground.
[0008] Figure 4 shows an alternative method of fitting the screening fence and/or the screen
5, which is therefore done when fitting the sleeve plates 2b and 2'b to the sectional
beams 1a and 1b respectively.
[0009] Figures 5a to 5b show perspective views of various possible embodiments of the invention.
Figures 5c to 5f show other possible sectional elements and sleeve plates, which are
outside of the scope of the claims.
1. Method of achieving a hollow sectional beam (1) by joining together longitudinal,
essentially U-shaped sheet profiles in pairs having an unessentially different cross
section, whereby a first pair (1a, 1b) is produced having a predetermined leg width
and a section between the legs, which defines a predetermined distance between the
legs, the sheet profiles (1a, 1b) of the first pair are slid into each other in such
a way that the legs of the respective sheet profile point towards the section of the
other sheet profile, characterised in that a second pair of sheet profiles (2a, 2b) is produced, each sheet profile of the second
pair having two legs and a section between the legs, the legs having flanges projecting
across the legs and the section length being related to the leg width or the section
length of the first sheet profile pair such that the sheet profiles (2a, 2b) of the
second pair can be placed with a tight fit on each side of the sheet profiles of the
first pair (1a, 1b) which have been slid into each other such that their legs or their
sections are covered by the mid section of the sheet profiles of the second pair of
sheet profiles (2a, 2b).
2. A hollow sectional beam (1) joined together by longitudinal, essentially U-shaped
sheet profiles having an unessentially different cross section, comprising a first
pair of sheet profiles (1a, 1b) having a predetermined distance between the legs and
a section between the legs which defines a predetermined distance between the legs,
the profiles (1a, 1b) being slid into each other in such a way that the legs of the
respective sheet profile point towards the section located between the legs of the
other sheet profile, characterised in that the beam comprises a second pair of sheet profiles (2a, 2b) each sheet profile of
the second pair having two legs and a section between the legs, the legs having flanges
projecting across the legs and the section length (2a2, 2b2) being related to the
leg width or to the section length of the first pair of sheet profiles in such a way
that the sheet profiles (2a, 2b) of the second pair of sheet profiles can be placed
with a tight fit tight on each side of the sheet profiles of the first pair (1a, 1b)
which have been slid into each other, whereby the legs or the section of the first
pair of profiles are covered by the respective mid sections of the sheet profiles
of the second pair of sheet profiles (2a, 2b).
