CORNER BOARDING ARRANGEMENTS
This invention relates to corner boarding
arrangements.
In the boarding of posts, girders and the like,
there are employed according to known engineering
practice, which has changed little the last 10-20
years, boarding elements which are held together by
means of various collars or the like which are
fastened with relatively short intermediate spaces
round the boarding and thereby hold the individual
boarding elements in position. This solution is
very demanding on labour and time in that the collars
have to be nailed to the boarding elements and have
to be renovated after use.
By the very fact that the boarding work in
many casting operations constitutes a substantial
portion of the costs, improvements are constantly
being sought after but, as mentioned above, without
significant changes having been made in engineering
in recent years.
The need for improvements is thus apparent and
the object of the present invention is to effect
boarding of corners more rapidly and simpler and
hence cheaper.
Accordln~:ly, the present invelltion resides in a
corner boarding arrangement comprising (a) first and
second plate means disposed at an angle to each other,
(b) an angled member having ~irst and second legs
forming an angle opposite and substantially equal to
said angle between said first and second plate means,
~,
"` ~;;~757~7
said first leg extending substantially at right angles
to the main plane of said second plate means while
projecting away from said first plate means and said
second leg extending suhstantia]ly a-t right angles
to the main plane of said first plate means while
projecting away from said second plate means, and (c)
first and second auxiliary members detachably fastened
to their respective first and second plate means to
form extensionsthereof and having adjacent ends dis-
posed at said angle between said first and secondplate means, and said first and second legs of said
angled member being detachably fastened to said second
and first auxiliary members respectively.
In order that the invention can be more clearly
understood, convenient embodiments thereof will now be
described, by way of example, with reference to the
accompanying drawings in which:
Fig. 1 is a cut~off horizontal section of a
corner boarding arrangement employed for boarding a
corner in a post by means of boarding cassettes,
Fig. 2 is a similar cut-off horizontal section
to Fig. 1 where the boarding is constructed of boarding
members, and
Fig. 3 is a perspective view of the arrangement
of Fig. 2.
Referring to Fig. 1, the angle a between the
boarding cassettes is 90.
Each boarding cassette consists oE two plates
lOa, lOa' and lOb, lOb' respectively, whtch are usually
made of plywood and which ilave a cel-l.a:itl spacirlg, for
example 10 ~m. roll~ eclcil ol:her. Each oE these plates
can alterncately face towards Lhe concrete. Between
the surfaces, there is arranged along their edges a
U-shaped element, legs oE which, such as the leg 16a,
project outwarclly as an extension of the p]ates. In
addition, the element is designed with an inwardly
projecting flange which the plywood plates form an
~7~7~
abutment against and which they are detachably fastened
to by means of, for example, rivets.
On boarding a corner, two boarding cassettes 10a,
10b are mounted at an angle a of 90 to each other.
something which, moreover, is the most customary. An
angled member 11, legs 12, 13 of which form an angle
which is as large as, but opposite relative to, the
angle a between the cassettes 10a, 10b, is arranged
between the outwardly projecting legs of each boarding
cassette. The member 11 forms thereby an abutment
against the bottom 14a, 14b of the U-shaped element of
the boarding cassette and forms with its free end 15a,
15b an abutment against the outwardly projecting leg
16a, 16b of the U-shaped element. At the top point of the
lS angled member 11 this is angled in the form of steps
so that it forms an abu-tment against the U-shaped
element which is an extension of the inner plate 10a,
10b. In this way, the angled member will be arranged
safely in position between the outwardly projecting
members and is fixed to the bottom 14a, 14b of the
U-shaped element by means of detachable bolts 17 or
clamps. As a result, the unit which consists of the
two boarding cassettes 10a, 10b and the angled member
11 will be held rigidly together with minimal possibi-
lities for displacement relative to each other. Also,while the angled member is usually made of aluminium,
it can also be made of other materials, for example,
galvanised steel. The breadth of the member 11 can be
varied from a relative]y narrow ~Itr;p l:o the whoLc
length or ~readl:h Oe l'hC! boardlng cassette ancl the
length of each leg corresE)onds to the distance between
the plates of the cassette.
In Fig. 2, there are employed boarding members
18a, l~b instead of boarding cassettes. Outwardly from
each boarding mernber, there projects substantially at
right angles to this, an elemen-t l9a, l9b with pro-
jections 20a, 20b which the boarding members are
~ 2757~7
detachably fixed to, for example, by means of rivets.
The elements l9a, l9b extend over the whole respective
length and breadth of the boarding member. A certain
section which is not critical projects outwardly from
the boarding member but is adapted to the length of
legs 12, 13 of the angled member 11. At its free end,
each of the elements l9a, 19b is angled so that the
free end of the member 11 forms an abutment against
angled portion 21a, 21b of the element l9a, l9b which
extends in an opposite direction relative to projection
20a, 20b of the element. In a corresponding manner to
the embodiment of Fig. 1, the angled member is fixed
to the element l9a, l9b by means of bolts 22 or rivets
so that the member 11 can be detached in a simple
manner from the element l9a, l9k after use. Also in
this embodiment, there is provided a reliable and good
bracing and locking.
In Fig. 3, it is clearly evident how the angled
member 11 is disposed relative to the elements l9a,
l9b. In the opposite direction relative to the angled
portion 21a, 21b, there projects a second angled portion
23a, 23b which functions as a support for rivets so that
they are not able to become displaced outside and
thereby no longer lock together legs of the angled
member 11 and the elements l9a, l9b.
While the invention is described in connection
with boarding, either by means of boarding cassette or
boarding members, it can be applied in the production
of dismountable containers or hoxe9 oE many di~ferent
types. Such all applicat:ion can prove to be very
interesting because of the great flexibility which
the arrangement of the invention makes possible.
