[0001] The invention relates to a building-up construction, comprising a first and a second
series of first and second building-up elements respectively for placing one on top
of the other, at least part of the first building-up elements being provided to be
placed on top of the second building-up element at an angle or inversely, and a recess
being provided in a building-up element of one series that is corresponding with a
projection that has been provided on a building-up element of the other series, the
projection being provided with two contact surfaces diverging in a first direction,
which, when placing the said building-up elements one on top of the other, will be
in contact with the corresponding contact surfaces of the recess of the building-up
element of the other series.
[0002] The invention is especially used for swimming pools and garden houses. However, other
applications are likewise possible.
[0003] For building-up a construction consisting, for instance, of planks, many connections
are possible. A classic connection is a dovetail joint, which is used especially for
its aesthetic aspect. For example, in U.S. 6,357,194 a dovetail joint ending in a
point is discussed, which is a method for connecting two boards or other solid materials.
[0004] Other known constructions have a horizontally sliding connection, and are kept together
by means of a bar of any possible material. For example, with known building-up constructions
for swimming pools, identical wooden planks are stacked one on top of the other by
means of a tongue-and-groove connection. The tongue here is made of stainless steel.
[0005] The disadvantage of such connections is that solidity is only obtained in case of
vertical pressure or through the corner connection. However, there are also building-up
constructions where the horizontal pressure is important, such as for instance, the
wind-force with building constructions and the water pressure with aboveground wooden
swimming pools.
[0006] The purpose of the invention is to provide a building-up construction not having
the above-mentioned disadvantages and in which the building-up construction is resistant
against the horizontal forces exerted by, among others, wind or water.
[0007] The purpose of the invention is achieved by providing a building-up construction,
comprising a first and a second series of first and second building-up elements respectively
for placing one on top of the other, at least part of the first building-up elements
to be placed on top of the second building-up element an angle or inversely, and a
recess being provided in a building-up element of one series that is corresponding
with a projection that has been provided on a building-up element of the other series,
the projection being provided with two contact surfaces diverging in a first direction
which, when placing the said building-up elements one on top of the other, will be
in contact with the corresponding contact surfaces of the recess of the building-up
element of the other series, but in which the projections are surrounded by the recesses
of at least two building-up elements of the other series, and the two contact surfaces,
diverging in the first direction, of the projection are also diverging in a second
direction at right angles to the first direction and away from the building-up element.
[0008] By the fact that the projection of the building-up element of the one series is surrounded
by the recesses of at least two building-up elements of the other series is meant,
that the projection of a building-up element of the one series is inserted into the
recesses of the building-up elements of the other series and consequently the projection
is surrounded by the walls of these recesses.
[0009] In this way, a building-up construction is obtained with the following advantages:
- stronger (against horizontal pressure);
- simple construction;
- absorbation of the swelling and shrinking motions, and tolerances of dimensions.
The building-up construction is preferably provided with an additional reinforcement
against horizontal water and/or wind pressure.
[0010] In a preferred embodiment of a building-up construction according to the invention,
the projection is provided with a recess extending between the contact surfaces and
provided for fitting a reinforcing element through two or more building-up elements.
[0011] In an advantageous embodiment of a building-up construction according to the invention,
a reinforcing element is provided with tightening means for tightening the building-up
elements against each other.
[0012] In a more advantageous embodiment of a building-up construction according to the
invention, the reinforcing element is carried out as a spindle, and the tightening
means are carried out as a nut provided around the said spindle and in at least one
of the extreme building-up elements of the building-up construction, in which a groove
is provided by providing the nut in the groove, the nut may be tightened for tightening
the building-up elements against each other.
[0013] This has the advantage that the spindle may be adjusted in a simple manner and in
this way the vertical tension of the construction may be adjusted. This adjustment
can be necessary for materials having shrinking properties such as wood, or to obtain
larger tolerances for the dimensions.
[0014] In a preferred embodiment of a building-up construction according to the invention,
the angle between the building-up elements of the first series and the second series
is an obtuse angle.
[0015] In a preferred embodiment of a building-up construction according to the invention,
the said recess provided in a building-up element of the first or the second series
is constituted by a projection provided on the same building-up element.
[0016] Preferably, all intermediate building-up elements of the building-up construction
of the first and the second series are made identical.
[0017] In a preferred embodiment of a building-up construction according to the invention,
each projection is provided with an end surface that is provided such that, in the
building-up construction, it is situated in the same plane as the outer face of a
building-up element of the other series.
[0018] In this manner, the building-up construction will have a better finish and there
will be no protruding beams, through which the safety is increased.
[0019] Preferably, the building-up elements of the first and second series respectively
are placed one on top of the other by means of a groove-and-tongue connection.
[0020] This has the advantage that the building-up elements may be easily placed one on
top of the other in the proper manner.
[0021] In the building-up construction according to the invention, the building-up elements
are preferably made of wood.
[0022] The building-up construction according to the invention is essentially used for swimming
pools.
[0023] This invention is further clarified in the following non-restricted description of
a preferred embodiment of a building-up construction according to the invention.
[0024] In this description, reference is made by means of reference numbers to the attached
figures, where:
- figure 1 is representing a perspective front view of part of the building-up construction
according to the invention;
- figure 2a is representing a perspective front view of part of a building-up element
from the first series;
- figure 2b is representing a perspective front view of part of part of a building-up
element from the second series;
- figure 3a is representing a top view of part of a solid building-up element;
- figure 3b is representing a side view of part of a solid building-up element;
- figure 3c is representing a bottom view of part of a solid building-up element;
[0025] As represented in figure 1, a building-up construction (1) according to the invention,
consisting of a first series of first building-up elements (10), which may be placed
one on top of the other and a second series of second building-up elements (20), which
may be placed one on top of the other, the first building-up elements (10) and the
second building-up elements (20) being provided to be placed mutually on top of one
another at an angle. The first and the second building-up elements (10,20), in order
to be easily placed on top of one another, are provided with a groove (100)-and-tongue
(200) connection. In the figure, this groove (100)-and-tongue (200) connection is
carried out as a single connection. It may also be carried out as a multiple connection.
Another possibility is that the building-up elements (10,20) are carried out in solid
way. Preferably, the angle between the first and the second building-up elements (10,20)
is an obtuse angle.
[0026] As represented in the figures 1, 2a and 2b, a recess (2) has been provided in a building-up
element of the one series, for instance in a first building-up element (10b) of the
first series, corresponding to a projection (3) which is provided in a building-up
element of the other series, for instance in a second building-up element (20b) of
the second series. As represented in figure 1, the projection (3) of a second building-up
element (20e) of the second series in the building-up construction is surrounded by
the recesses (2) of at least two first building-up elements (10e,10f) of the other
series. On the other hand, the projection (3') of a first building-up element (10d)
of the first series is surrounded by the recesses (2') of at least two building-up
elements (20d,20e) of the second series. In figure 1, each projection (3,3') is surrounded
by two building-up elements (10,20) of the first or second series. However, in order
to obtain another view, two different building-up elements may be placed on top of
one another and thus constitute a surrounding for a projection (3,3'), which is not
represented in the figure.
[0027] As represented in the figures 2a and 2b, the projection (3) has the geometrical shape
of a parallelepiped and is provided with two contact surfaces (4,4') diverging in
the first direction (see arrow A). When placing a first and a second building-up element
(10,20) on top of one another, these contact surfaces (4,4') are in contact with the
corresponding surfaces (5,5') of the recess (2) of the building-up element (20a) of
the second series. Furthermore, these contact surfaces (4,4') are diverging in a second
direction (arrow B) away from the building-up element (20a) and at right angles to
the first direction (arrow A).
[0028] In this preferred embodiment, the recess (2) is constituted by a projection (3')
which is also part of a first building-up element (10). In addition to this, all intermediate
building-up elements (10,20) are carried out to be identical. By the intermediate
building-up elements (10b - 10f and 20b - 20g) are meant the building-up elements
situated between the lower building-up element of the first and the second series
(10g,10h) and the upper building-up element of the first and the second series (10a,20a).
However, the extremities of each intermediate building-up element (10b - 10f and 20b
- 20g) are carried out to be each other's mirror images, as also represented in the
figures 2a and 2b. The end faces (6,6') of the projections (3,3') are carried out
such that each end face (5,5') in the building-up construction is situated in the
same plane as the outer face (7,7') of a building-up element of the other series.
In other words, the end face (6) of the projection (3') of a first building-up element
(10) of the first series is in the building-up construction situated in the same plane
as the outer face (7') of a second building-up element (20) of the second series,
and the end face (6') of the projection (3) of the second building-up element (20)
from the second series is situated in the same plane as the outer face (7) of the
first building-up element (20) of the first series. In this way, there are no projecting
parts in the building-up construction (1).
[0029] As represented in the figures 3a to 3c, the dimensions of the building-up elements
(10,20) in the preferred embodiment as described here, have specific proportions with
respect to one another, in order to obtain a sufficiently strong, easy to build and
aesthetically nice building-up construction (1). The width of the building-up element
(10,20) is therewith represented by a and the width of the building-up element (10,20)
is represented by b.
[0030] When building up this preferred embodiment of a building-up construction (1) according
to the invention, as represented in figure 1, first the lower building-up element
(20h) of the second series and the lower building-up element (10g) of the first series
are placed next to one another on the building surface. Then a next building-up element
(20g) of the second series is placed on the lower building-up element (10g) of the
first series, in such a manner, that contact surface (5') of the projection (3) of
the building-up element (20g) of the second series will get into contact with the
contact surface (4') of the lower building-up element (10g) of the first series. Then,
in the same manner, the next building-up element (10f) of the first series is placed
upon the building-up element (20g) of the second series.
[0031] Because the projection (3,3') of a building-up element (10,20) is enclosed by at
least two building-up elements (10,20) of a same series (as described above) and the
projection (3,3') has the shape of a parallelepiped with in a first direction (arrow
A) and in a second direction (arrow B), at right angles to the first direction and
away from the building-up element (10,20), the building-up construction (1) can only
be realized by building up and not by sliding the building-up elements into one another.
In this manner, a strong whole is obtained, resisting horizontal pressures such as
water pressure and air pressure.
[0032] In order to increase the resistance of the building-up construction (1) still more
to wind or water pressure, the building-up construction (1) is provided with a reinforcement.
In the preferred embodiment as represented in figure 1, between the contact surfaces
(4,4' and 5,5') of the projections (3,3'), a recess (8,8') is provided, in which the
reinforcing element (not represented in the figure) may be installed. Preferably,
this reinforcing element is running through all building-up elements (10a - 10g and
20a - 20h). The reinforcing element is provided with tightening means (not represented
in the figure) to tighten the building-up elements (10,20) against each other. In
this preferred embodiment, the reinforcing element is carried out as a threaded spindle.
The tightening means are carried out as a nut provided around the threaded spindle.
To install this nut, the lower building-up element (10g) of the first series and/or
the upper building-up element (20a) of the second series is provided with a groove
(9,9'), in such a manner that the nut may be tightened to tighten the building-up
elements (10,20) against each other. In this preferred embodiment, both in the lower
building-up element (10g) of the first series and in the upper building-up element
(20) of the second series a groove (9,9') has been provided.
The reinforcing element may likewise consist of a bar, a screw or suchlike. Moreover,
the reinforcing means may also consist of a glue being applied between the contact
surfaces (4,5 and 4',5') of the projections (3,3'). In this case, of course no recess
(8,8') has to be provided in the projections (3,3').
A combination of two or more reinforcements as discussed above is also within the
possibilities.
By providing reinforcing means, swelling and shrinking motions and tolerances of the
dimensions may be absorbed. When a threaded spindle with a nut is used as a tightening
system, moreover, building up the building-up elements around this spindle may be
carried out easily, and the vertical tension of the building-up construction may be
adjusted in a simple manner.
[0033] Preferably, the building-up elements (10,20) are made of wood, but they may be manufactured
from other material. This building-up construction (1) according to the invention
is especially used for swimming pools and garden houses. However, the building-up
construction (1) may also be used for other applications.
