[0001] The present invention concerns an arrangement for joining wood-based construction
elements according to the introduction of claim 1.
[0002] The manufacture of houses and other types of building takes place evermore often
with the aid of construction elements, for several reasons. Not only is it possible
for the assembly of the house to take place with fewer persons involved at the building
site, but also is the manufacture of the construction elements carried out in a controlled
environment, such as that in a factory. The construction elements comprise modules
that are put together, forming in this manner a building. The module may be fully
complete, with its outer surface coated with a weather-resistant surface layer, the
inner surface wallpapered, and the interior of the module provided with insulation
and conduits installed for, for example, the electrical installations. The module
may be one complete wall, a wall with at least one of windows and doors, and floor
structure modules.
[0003] Various methods and arrangements for the joining of construction elements are known.
A joint between two construction elements consisting of solid wood for the completion
of multi-storey buildings is described in the Swedish patent
SE 515784, with applicant Martinsons Trä AB. The elements form not only load-bearing wall elements
but also floor structure elements. The various parts are locked to each other with
the aid of grooves and projections placed in the edges of the elements.
[0004] One disadvantage of this variant is that the motions of the modules are limited by
the grooves in combination with the weight of the modules.
[0005] US2002/0100235 discloses a construction panel in the form of both horizontally and vertically oriented
elements. The elements are attached to each other or to an existing building by a
variety of attachment mechanisms such as nuts and bolts, screws or nails. The vertical
building element is attached to the horizontal element by screws or nails. The horizontal
element includes a part that fits into a pocket created between two vertical elements,
and the part is held in place in the pocket with nails or screws.
[0006] DE19702860 discloses a wooden house assembled from prefabricated panels. A first wall panel
is positioned on top of a second wall panel. Between the wall panels is inserted a
beam shoe in which a beam from a floor element rests. The beam shoe is inserted is
a gap between the wall panels. The wall panels have flat ends, and are held in place
and in line by attaching the wall covering.
[0007] One aim of the present invention is to offer an arrangement for the assembly of wood-based
floor construction elements that gives an exact fitting of the elements to each other.
[0008] A second aim is to offer an arrangement for the fitting of the construction elements
against each other that gives at the same time locking in both the vertical direction
and the horizontal direction during the joining process.
[0009] An embodiment will be described below with reference to the attached drawings, of
which:
Figure 1 shows a construction element arranged horizontally with a lamellar board,
Figure 2 shows a detail of an I-beam,
Figure 3 shows a detailed view of notches placed in the edge of the wall element,
Figure 4 shows the form of a sound-insulating material,
Figure 5 shows a suspension bracket,
Figure 6 shows a cross-sectional drawing of a floor construction element before it
is joined to a wall element,
Figure 7 shows a cross-sectional drawing of the floor construction element after it
has been joined to two wall elements,
Figure 7A shows a further variant of the joint, and
Figure 8 shows a cross-sectional drawing of the completed joint.
[0010] Figure 1 shows, according to a preferred embodiment, a construction element 1 in
the form of a wall element 1A, 1A.1 or a floor construction element 1B, manufactured
from wooden material. The construction element 1, which for reasons of clarity will
be described as standing in a vertical direction when it is a wall element 1A and
laying in a horizontal direction when it is a floor construction element 1B, comprises
a structural body having supporting battens of elongated I-beams 2, one of which is
shown in more detail in Figure 2. It is an advantage if the webs 3 of the I-beams
2 are manufactured from wood-fibre sheet. The two edges of the web 3 are attached
at the sides to a pressure flange 4 and a tensile flange 5 manufactured from wood.
These may be, for example, solid wooden flanges, or they may also comprise LVL material
or glulam. The term "pressure flange" 4 is used to denote the flange at which compression
forces usually arise, and in an equivalent manner, the term "tensile flange" 5 to
denote the flange at which tensile forces usually arise, in particular in the case
of floor construction elements. The beams 2 are arranged essentially parallel to each
other and at a certain separation, with their tensile flanges 5 attached to a first
surface covering 6, for example a building sheet, adapted for an outdoor environment
and advantageously provided with facade material such as panels or similar. It is
appropriate that the separation between the beams 2 be adapted for insulation material
of standard dimensions. It should be realised in this respect that the beams can be
arranged with a greater or lesser distance between them, depending on the load that
it is intended that the construction element 1 is to carry, and depending on whether
the construction element 1 is to be insulated or not. It is an advantage that nogging
pieces be arranged between the I-beams 2. It is an advantage if also a transverse
I-beam be arranged at the end pieces 8a, 8b of the I-beams.
[0011] A plate 9 in the form of a lamellar board is attached to the pressure flanges 4 of
the beams 2, which plate comprises a core 10 with fibres that are parallel to the
longitudinal direction of the I-beams, and which core is covered by a surface layer
11 on at least the side that faces the I-beams 2. It is an advantage that the core
10 comprise planks 12 that are arranged with their long sides next to each other and
parallel with the I-beams 2. The size of the plate 9 depends on the load to which
the wall element 1A will be subject when the building has been built. When using the
wall element for walls of buildings that will be subject for light vertical loads,
the pressure flange side 4 of the beams 2 is only partially covered by the plate 9,
since the load on the wall element 1A will be significantly lower than it will be
in a multi-storey building. The pressure flange side 4 is thus covered by the plate
9 solely on that part that is adjacent to the ceiling, when viewed in a vertical direction.
That part of the pressure flange side 4 of the I-beams 2 that is not covered by the
plate 9 is, instead, arranged with a traditional type of building board. The arrangement
of the sheet in this manner can be compared with a traditional truss beam. If the
wall element 1A is to be used in a building with a heavy vertical load, such as a
multi-storey building or an industrial building, then the pressure flange side 4 of
the wall element 1A is fully covered by the plate 9.
[0012] For a floor construction element that is intended to be used horizontally, one of
the flanges of the beam, the one known as the "tensile flange", may be provided with
a means of absorbing tensile forces in the form of carbon fibre or steel tape. During
use of the floor construction element 1 B, the end parts of the I-beams 2 are covered
by a plate 9 at the end walls 13 of the floor construction element 1 B. The pressure
flange side 4 is arranged with a traditional floor plate. If, however, the span is
large and calculations have shown that the downwards curvature and the vibration properties
require a stiffer design, then the complete pressure flange side is arranged with
a plate 9 in the form of a lamellar board or LVL plate.
[0013] An arrangement is arranged at each end wall 13 in the form or a hook or bracket 14.
This can be seen in Figure 5, and has been given the form of a sharply angled "S".
The bracket 14 demonstrates a principal surface 15 having a width, and it demonstrates
flange surfaces 16a, 16b at the edges of its two end pieces, which flange surfaces
are angled perpendicularly away from the principal surface 15, one 16a of the flange
surfaces being angled in one direction and the other 16b of the flange surfaces being
angled in the other direction. The bracket 14 is screwed, or attached by another suitable
method, to the floor construction element 1B with its principal surface 15 essentially
parallel to the end wall 13 of the floor construction element. One 16a of the flange
surfaces is positioned such that it is directed in towards the floor construction
element 1 B in contact with the end plate 9 of the element, whereby the other 16b
flange surface protrudes from the end 13 at the same level as, or somewhat under,
the edge 18 of the plate 9. The free end of the second 16b flange surface demonstrates
an end piece 19 essentially parallel with the principal surface 15 forming an inverted
"U" with the principal surface 15.
[0014] The plate 9 and the I-beams 2 of the wall element 1A are arranged, according to Figures
6-8, such that one end part 20 of the plate 9 is located a distance inside one of
the ends 8a of the I-beams 2, and the other end part 21 of the plate 9 is located
a distance outside of the other of the ends 8b of the I-beams 2. This means that the
plates 9 and the supporting battens 2 of a wall element 1A that is stacked on top
of another wall element 1A.1 will be in contact with each other, but at different
levels. When a floor construction element 1B and two wall elements 1A, 1A.1 are used,
a joint is formed with the form of a tongue-and-groove joint 22 with a groove 23 and
a tongue 24, where the groove 23 is formed between the plate of the floor construction
element 1 B and the plate of one of the wall elements 1A, and the tongue 24 is constituted
by the plate 9 of the other wall element 1A.1.
[0015] The end parts 20, 21 of the plate 9 in another embodiment that is shown in Figure
7A are at a level with the transverse I-beam that is arranged at the ends 8a, 8b of
the longitudinal I-beams, i.e. when the wall elements are stacked vertically on each
other, one on top of the other, then the elements will make contact at their ends
without a tongue-and-groove joint being formed.
[0016] The plate 9 of the wall element 1A is, according to Figure 3, provided with a notch
25 that is present at the edge 18 of the plate 9 that is directed towards the ceiling,
when seen in the vertical direction. A sound-absorbing and vibration-absorbing material
17 is placed into the notch, which material covers all surfaces of the notch as seen
in Figure 4. The material comprises in another embodiment of the invention a tape
that is arranged in the notch 25. Corner pieces of the same material may be placed
at the corners of the notch 25 if the design requires this. The notch 25 has been
given an extent that corresponds to, or is somewhat greater than, the width of the
bracket 14 of the floor construction element 1B. When the floor construction element
1 B is to be installed, the bracket 14 is positioned at the position of the notch
25 in the plate 9. The inverted "U" form of the bracket is subsequently placed in
contact with the sound-absorbing and vibration-absorbing material 17 in the notch
25. The extent of the notch 25 ensures that the bracket 14 is in contact with the
notch and the material 17 at three of its edges, and thus prevents motion of the floor
construction element 1 B in the horizontal direction.
[0017] The arrangement functions as described below, with reference to Figures 6-8:
Laying the foundation is carried out in the normal manner through a pouring of the
foundation of the building or through an assembly of the elements of the crawlspace.
A sill is arranged at the beam at the edge, after which the first level of wall elements
1A is attached in a conventional manner. When the first level of wall elements has
been attached to the sill, the corners are joined in a manner that is already known,
for example, with the aid of tracks and riders or with the aid of ready-made corner
pieces. A tape of sound-absorbing and vibration-absorbing material 17 is placed in
the notches 25, and a strip of sealing material is placed on the edge of the wall
element 1A for sealing between the elements. End pieces of the same material are placed,
as described above, also at the edges of the notches, if this is required. The floor
construction elements 1 B which have been given a span that corresponds to the distance
between the wall elements 1A, 1A.1 that face each other, and which have been provided
at their end walls 13 with brackets 14 according to the invention, are subsequently
lifted into place with the brackets located in the notches 25.
[0018] When all floor construction elements have been lifted into place, the deployment
of the next level of wall elements begins, if the building is of multi-storey type.
Each wall element is lifted up and positioned such that it is in contact with a previously
placed wall element, after which the elements are lowered. In association with the
lowering of the wall element 1A, the end part 21 is placed at the edge 19 of that
part of the lamellar board 9 that is located outside of the ends 8b of the I-beam
2, making contact with the part of the existing wall element 1A.1 that comprises the
notch with the bracket 14 of the floor construction element. Also the vertical motion
of the floor construction element is thus locked in this manner. When all wall elements
at this level have been deployed as specified by the description above, the corners
are joined, after which the deployment of the floor construction elements of the next
storey is repeated.
[0019] It is an advantage if the component parts of the coupling arrangements described
above are manufactured from at least one of high-strength steel and stainless steel.
It should, however, be realised that other types of material, such as composite materials,
can be used.
[0020] It should furthermore be realised that the construction element described above may
be of a different design, for example, one using supporting battens of solid wood.
A further type of construction element comprises elements of solid wood, i.e. construction
elements manufactured from, for example, glulam beams that are joined together to
form a construction element.

in the drawings: it can be changed and modified in a number of different ways within
the scope of the innovative concept specified by the attached claims.
