METHOD AND MEANS TO ASSEMBLE A BUILDING BOARD ON A SUPPORT
Abstract
A method to safely mount a building board on a bedding, so that
the front surface of the boarding does not get penetrated during
the time glue applied between the board and the bedding is curing
or getting stiff. The method is characterized in that friction
increasing elements are applied at the bedding in connection to its
lower part, that glue is applied to the bedding, preferably in the
shape of a string, that the board is fit up against the bedding and
adjusted, and then a force is applied on the lower part of the
boarding at the position of rearward arranged friction increasing
elements such that these element are activated and penetrate the
rear surface of the board and assist in holding the whole weight of
the board.

Description
[0001] The present invention relates to a method and means to mount
a building board on a bedding, more precisely to safely hold a
building board on the bedding during the time necessary for glue
applied between the board and the bedding to cure or to get
stiff.
PRIOR ART
[0002] Today building boards of different materials and sizes are
used in building sites in a great extend. The reason for this is
the possibility to obtain a smooth and as far as possible "ready"
surface, i.e. a surface that needs a minor extra work prior to
painting or paper-hanging. Usual materials is e.g. plaster, chips,
wooden particles, composite, cement and materials based on glass.
These are used for covering or as support for other materials in or
onto floors, walls and ceilings. The support can be of steel or
wood, or of a combination of these materials, but also a wall of
concrete or a plastered surface or the like can be covered by a
building board. The most frequent building technique using building
boards is in so called light buildings using a frame work of wood
and/or steel. Joists in the frame work are mounted vertically with
a c/c of 450/600 mm on, over and below joists, (rails) and will
form a building framework. Frames for the ceiling and floor are
mounted in a similar way. After that the boards are most often
mounted by screwing. Frequently used building boards are of plaster
and having a width of 900/1200 mm and a length of 2400/2500 mm. It
takes about 50 screws to mount a board, The screwing of plaster
boards is time consuming and demands a great deal of work. The
screw heads must be drawn so far into the building board that they
do not leave any bumps on the board surface, but the smoothness of
said surface must be re-established by putty up the depressions of
screw heads and board joints. Here there is a risk that the screw
thread will crush the gypsum paste, which will jeopardize the force
acting onto the board(s). As a consequence of the monotone and
repeated working sequences during screwing, it can be mentioned
that just 2-3% of the person's daily working with wall mounting are
able to work till retirement. A wall mounting worker will handle
about seven boards each hour, each board is screwed with 50 screws,
which will result in 350 monotone moments performed each hour and
that 2800 moments are performed each working day. Common injuries
are in shoulders, neck and back. Whitening fingers caused by
vibrations from the screwing machines are also common. When
screwing through the boards an initially smooth surface is
penetrated and must be treated afterwards e.g. by filling. Lately
boards have been glued at the same time as the amount of screws has
been decreased to make it easier for the workers. Thus, screws do
not have to be used to keep the board in position during curing of
the glue, which often is water based. Still the problem with a
damaging influence on the outer surface of the board remains.
[0003] There have also been efforts made to use double adhesive
tapes. The disadvantage using tapes is that the boards cannot be
properly adjusted during mounting. Thus this method is not used in
an significant scale.
THE PURPOSE OF THE INVENTION
[0004] The outer most purpose of the present invention is to obtain
a technique which essentially will decrease the need for an after
treatment of a mounted building board. More precisely the purpose
of the invention is to suggest a technique which is useful to
properly hold the building boards towards an at least partly glue
covered bedding during curing of the glue. This is performed
without the need of penetrating attachment means on the front
surface of the board. This technique makes it possible to use
building boards with a completed finished surface which will result
in many advantages of both economically and time saving kind.
[0005] An other purpose of the invention is to suggest a technique
making it possible to build several onto each other arranged layers
of building boards to form a strong monocoque construction and
without the joints of the boards being positioned above a rear
frame work joist.
[0006] Yet another purpose of the present invention is to obtain a
possibility to hold building boards towards hard and/or uneven
bedding during the time it takes for a glue to cure.
[0007] Still an other object of the present invention is to suggest
a technique which will accelerate the curing of applied glue.
[0008] The purposes above are obtained by the present invention by
a method and means having the characterising clauses mentioned in
the claims.
GENERAL DESCRIPTION OF THE ADVANTAGES OF THE INVENTION
[0009] By using means to hold the building board safely against the
bedding and which means does not influence to outer surface of the
board during the time when an applied glue on the bedding is
curing, the front surface of the board will be intact and thus
without any need of after treatment.
[0010] The lateral force to be exerted onto a vertical board placed
on a bedding has to be as big to create a friction grip with the
bedding which will hold the weight of the board.
[0011] By the invention an improvement of the friction force is
suggested by using separate friction devices or pins, here called
"pin anchor" which preferably are mountable onto a lower rail by
clips in connection to a vertical joist and which pin anchor has at
lest one pin element directed outwards. This or these pin anchors
may, after having been activated, take the whole or at least a
major part of the weight of the board. Thus this will stop the
board from sliding after being applied onto glued bedding. This
means that less aggressive and less quick adhering glue may be
used, i.e. a glue admitting certain after adjustment of the board
if necessary. The pin anchors can also be used and attached to e.g.
a concrete wall by using e.g. tape or gluing. Also other
attachments methods can be used. There are pin anchor of different
types dependent of which board material to be anchored and at which
bedding this shall be performed. The density of the board material
and the character of the bedding and also the material in the pin
anchor have an influence of the attachment and the method of
anchoring, both of the pin anchor itself in the bedding and of the
attachment between the pin anchor and the board. However, this is
something that the man skilled in the art can find out with
guidance of what is presented here. Common for a pin anchor is that
it has at least one penetrating means being able to penetrate the
rear surface of the board a distance being less than the thickness
of the board. The pin anchor will facilitate a mounting of the
board on the bedding by admitting the worker to fit up the board
onto the bedding and adjust it at the same time as it is brought
upwards. At a correct position the worker will press the lower part
of the board with his foot in a direction perpendicular to the
bedding such that at least one pin anchor in connection to the
bedding is activated by having its pin means penetrating the rear
surface of the board and thus assist in holding the whole weight of
the board.
[0012] A transverse force to hold and press the board towards the
glued bedding during the curing of the glue is created by using
magnetic means cooperating with a magnetic material in connection
to the bedding or constituting the bedding in form of a steel joist
or rail. It is also possible to arrange inserts of magnetic
material in e.g. girders of wood. It is also possible to
glue/nail/screw/tape a magnetic material on the bedding if this is
a wood frame, a concrete wall, or another building board. Different
arrangements with magnetic means and holder for these means can be
used within the scoop of the invention. The force executed to hold
the building board is dependent of the magnetic flow passing
through the board which in turn is dependent of the size and to a
certain extent of the shape of the magnetic material at the
bedding. In the case the glue is of a heat curable kind a hysteris
influence can be created by using electro magnets, which will
create heat in the magnetic bedding and thus will speed up the
curing. It is also possible to create heat by vibrations, or use
glue being cured by being exposed to vibrations.
[0013] By using rulers carrying magnetic devices along its length
an evenly distributed force pressing the board towards the bedding
is possible to obtain. Glue is applied on the bedding by use of
e.g. a battery powered joint ejector. Several alternative devices
for applying glue being environment friendly, quiet and efficient
are to be found on the market. The glue can also be enveloped in
different ways depending upon equipment and working site,
(tube/folie, can/barrel).
[0014] Preferably the pin anchor is used when the magnetic rulers
are to be reused more frequently. Thus this will decrease the
amount of rulers necessary on a working site.
[0015] Thus the glue has just to get stiffen and not cure to
establish a sufficient holding force between the bedding and the
board. From a handling point of view the magnetic rulers may be
arranged with a telescopic function. Dependent upon the choice of
glue, air humidity and temperature the magnetic rulers will now
press the board against the bedding until the glue is
stiffened/cured. When this has happened they will be removed and
may be reused. There may be advantages in using this method. The
mounting is almost soundless/free from vibrations and gives the
workers a good working environment with very low stress on the
body. No filling of screw heads saves time and money. Further the
method opens the market for a new type of more refined boards as
the outer surface of the boards does not need to get damaged.
[0016] With special glues, and if outer circumstances admit it, the
mounting of boards may take place just using pin anchors and
glue.
