[0001] The present invention relates to an assembly of a carrier and a filling element,
more particularly to an assembly of a skeletal structure of a building, comprising
at least carrier and a filling element.
[0002] The invention is further related to such a filling element, and a method for the
application thereof.
[0003] Applicant develops floor systems that comprise filling elements, which are an integral
combination of ceiling, installation space and subfloor. Construction and installations
are integrated by utilizing an installation space between the ceiling and the subfloor.
A filling element of such a floor system comprises supporting steel beams and concrete
plates, which are combined in prefabricated elements that may be topped with a subfloor
of choice. European patent
EP-B1-0928354 describes such a floor system.
[0004] The wind load on a facade of a building is absorbed through the steel beams or concrete
plates of the filling elements directly. The load is transferred to the skeletal structure
through a so-called diaphragm action. The individual filling elements are traditionally
connected on site by welding operations. Steel connection plates are welded between
a steel beam of a filling element and a steel part of the skeletal structure.
[0005] Welding has a number of disadvantages. Besides being laborious and time consuming,
it also requires skilled craftsmen that are trained in welding. Sparks that are inevitably
caused by the welding operation may damage the building, and cause corrosion. Moreover,
the sparks may leave dark spots that are undesirable and that result in a perception
of diminished quality.
[0006] European patent application
EP 2 463 452 A2 is considered the closest prior art, relative to which at least the features of the
characterizing portion of claim 1 are novel. It discloses an assembly according to
the pre-amble of claim 1. The I-shaped beam is bolted to a carrier.
[0008] An object of the present invention is to provide an assembly that is improved relative
to the prior art and wherein at least one of the above stated problems is obviated.
[0009] Such objectives as indicated above, and/or other benefits or inventive effects, are
attained according to the present disclosure by the assembly of features in the appended
independent device claims and in the appended independent method claim.
[0010] The assembly according to the invention comprises:
[0011] By providing a bolted connection, there is no need for welding operations anymore.
Bolted connections are easy and quick to arrange and may be applied by any worker.
There is no need for skilled craftsmen trained in welding. Moreover, a bolt connection
is releasable, which may allow for a release, e.g. for decommissioning.
[0012] Relative to European patent application
EP 2 463 452 A2, the extension of the first plate is supported on the carrier. As a result, the filling
element may be placed on the carrier as a first step. In a second step, the bolted
connection may additionally be arranged to connect the beam to the carrier. After
the filling element being placed on the carrier, it is already securely supported,
i.e. securely resting on the carrier. There is no need to suspend the filling element
by any hoisting equipment during arrangement of the bolted connection, reducing the
time and need for heavy hoisting equipment, such as cranes. A crane may be used to
successively place a plurality of filling elements on carriers of the assembly, while
the second step of arranging the bolted connections is delayed until a later time,
when the crane may be gone. There is no need for the crane to support the filling
elements when they are bolted to the carrier, as is required according to the prior
art solutions disclosed in
EP 2 463 452 A2,
WO 00/46459 A1,
CN 106 869 325 A and
US 2004/244330 A1.
[0013] The beam being a structurally integrated part of the filling element with the plate
provides a robust and stiff filling element that, via the extension, may be easily
supported on a carrier as a whole.
[0014] The vertical offset between the bolted connection and the extension provides a stiff
assembly after the bolted connection has been arranged.
[0015] According to a preferred embodiment, the extension is plate-shaped and oriented in
a lying plane on the carrier. In this way, the extension has a relatively large contact
surface over which the load of the filling element is distributed to the carrier.
[0016] According to a further preferred embodiment, the extension is freely supported on
the carrier. Due to the extension being freely supported, i.e. supported in a non-fixed
manner, it is effectively prevented that the assembly is overconstrained. As a result,
unnecessary stresses in the assembly are prevented, contrary to the bolted assemblies
as proposed in the prior art.
[0017] According to an even further preferred embodiment, the first flange of the I-shaped
beam is an upper flange extending at a distance from the plate and comprising the
extension supported on the carrier, and the second flange of the I-shaped beam is
a lower flange that is embedded in the plate. If the upper flange of the I-shaped
beam is provided with the extension, it can be easily placed on top of a carrier,
without the need of tilting the filling element in order to move the extension past
an upper flange of a carrier before it can be positioned on a lower flange of said
carrier.
[0018] According to an even further preferred embodiment, the bolted connection is configured
to connect a connector of the filling element and the carrier. The connector may be
arranged on the plate of the filling element. For example, if the plate is made out
of concrete, the plate may be a metal plate that comprises extensions that extend
inside the concrete of the plate. Typically, the connector may comprise extensions
that are poured into the concrete during manufacturing of the plate of the filling
element.
[0019] According to an even more preferred embodiment, the bolted connection is configured
to connect the I-shaped beam of the filling element and the carrier. The I-shaped
beam is a very robust and rigid structural component of the filling element, and is
therefore perfectly suited for obtaining a rigid and reliable connection.
[0020] The invention further relates to a filling element, comprising:
- a plate;
- an I-shaped beam of which a first flange extends at a distance from the plate and
comprises an extension configured to be supported by a carrier, and of which a second
flange is connected to the plate, and further comprising a support configured to support
a bolted connection. Such a filling element may be prefabricated, and the support
prepares the filling element to be used in an assembly according to the invention.
[0021] Also, the invention relates to a method, comprising the steps of:
- providing a skeletal structure and/or a wall bearing structure of a building, comprising
at least one carrier;
- providing a filling element extending from the carrier, said filling element comprising
a plate and an I-shaped beam of which a first flange comprises an extension extending
over a distance from the plate;
- wherein the beam is a structurally integrated part of the filling element with the
plate; and
- the method further comprises the steps of:
- positioning the extension of the first flange on the carrier;
- connecting the filling element to the carrier at a vertical offset from the extension
with a bolted connection, while the first flange is resting on the carrier, said carrier
thereby supporting the filling element.
[0022] Preferred embodiments are the subject of the dependent claims.
[0023] In the following description preferred embodiments of the present invention are further
elucidated with reference to the drawing, in which:
Figure 1 is a perspective view of a skeletal structure of a building comprising carriers
and a filling element according to the invention;
Figure 2 is a detailed perspective view of an I-shaped carrier of the skeletal structure
of the building of Figure 1, and a filling element according to the invention;
Figure 3 is a detailed cross sectional side view of the assembly of Figure 2; and
Figure 4 is a detailed cross sectional exploded view of the assembly of Figure 2.
[0024] The assembly 1 shown in the Figures comprises a skeletal structure 2 of a building
3, wherein said skeletal structure 2 comprises at least one carrier 4, and a filling
element 5 extending from the carrier 4. In the shown embodiments, carrier 4 is an
I-shaped carrier. The filling element 5 comprises a plate 6 and an I-shaped beam 7.
A first flange 8 of the I-shaped beam 7 extends at a distance from the plate 6 and
comprises an extension 9 supported by the carrier 4. A second flange 10 of the beam
7 is connected to the plate 6. The assembly 1 further comprises a bolted connection
11 connecting the I-shaped beam 7 of the filling element 5 and the carrier 4. The
bolted connection 11 allows the filling element 5 to be connected to the carrier 4
of the skeletal structure 2 without any welding operations. In this way, disadvantages
that are associated with welding can be prevented, while a secure connection is maintained.
[0025] Preferably, the filling element 5 is arranged between carriers 4 that are part of
opposite structural walls of the building 3. The filling element 5 then spans from
a first structural wall to a second structural wall of the building 3.
[0026] As can be best seen in the perspective side view of Figure 3, the extension 9 and
the bolted connection 11 are vertically offset. This improves the diaphragm action.
Preferably, the bolted connection 11 is arranged closer to the second flange 10 of
the beam 7 of the filling element 5 than to the first flange 8 thereof. More preferably,
the bolted connection 11 is arranged at or near the second flange 10 of the beam 7
of the filling element 5.
[0027] The bolted connection 11 comprises a bracket 12. In the shown embodiment, this bracket
12 has a L-shape of which a first section 13 extends substantially in line with a
longitudinal direction of the filling element 5. A second section 14 of the L-shaped
bracket 12 extends transverse to the first section 13 and substantially parallel to
a web 15 of the carrier 4. Although the second section of the L-shape of the bracket
12 may abut directly against the web 15 of the carrier 4, alternatively one or more
than one spacer 16 may be arranged between the bracket 12 and the web 15 of the carrier
4. Such a spacer 16 may be used to fill a gap and allow the bracket 12 to abut indirectly
against the web 15 of the I-shaped carrier 4 via said intermediate spacer 16. Using
spacers 16, the bolted connection 11 is easily adjustable on site.
[0028] The second section 14 of the bracket 12 comprises a first through hole 17, and the
web 15 of carrier 4 comprises a second through hole 18. In an assembled state of the
assembly 1, the through holes 17, 18 are aligned, and a bolt 20 is arranged through
a passage formed by said through holes 17, 18. If a spacer 16 is applied, a corresponding
through hole 19 is arranged in said spacer 16. A nut 21 may be arranged on bolt 20
to clamp the bracket 12 against the carrier 4.
[0029] The beam 7, which is preferably made out of steel, is embedded in the plate 6 with
the second flange 10 thereof. The plate is preferably made of concrete, although it
may also be manufactured from other materials, such as composites or epoxy. A plate
6 made out of concrete is strong enough to be walked on by craftsmen. On the one hand,
the concrete plate 6 acts as a support for building installations. On the other hand,
plate 6 provides horizontal stability of the construction of the building 3. Moreover,
concrete offers fire resistance and acoustic insulation.
[0030] A secure and accurate positioning of the bolted connection 11 may be obtained if
the filling element 5 further comprises a support 22 configured to support the bolted
connection 11. If such a support 22 is applied, the bolted connection 11 is connected
indirectly to the I-shaped beam 7 of filling element 5, i.e. via said support 22.
Preferably, the support 22 is arranged on the second flange 10 of the beam 7. As can
be best seen in Figure 3, the support 22 of the shown embodiment extends from the
second flange 10 of the beam 7 towards the first flange 8 thereof. In a preferred
embodiment, the support 22 extends from the second flange 10 past the plate 6. In
this way, the support 22 is a little bit higher than the concrete of plate 6, and
provides a reliable support for the bolted connection 11. The support 22 is preferably
made out of steel and provides an engagement surface 23 for the bracket 12 of the
bolted connection 11. The first section 13 of the L-shaped bracket 12 abuts against
the engagement surface 23 in an assembled state of the assembly 1.
[0031] The support 22 may further comprise one or more than one protrusion 24, such as shafts
25. These protrusions 24 allow the bracket 12 to be positioned securely. If the shafts
25 are provided with an external screw thread, a nut 26 may secure the bracket 12
on the support 22.
[0032] The filling element 5 according to the invention thus comprises a plate 6 and an
I-shaped beam 7 of which a first flange 8 extends at a distance from the plate 6 and
comprises an extension 9 configured to be supported by the carrier 4, and of which
a second flange 10 is connected to the plate 6, and further comprising a support 22
configured to support a bolted connection 11. Such a filing element 5 may be prefabricated
and provided with a bolted connection 11 on site.
[0033] In Figure 4, a connector 27 is arranged on the plate 6 of the filling element 5.
The connector 27 may be provided with one or more than one protrusion 28, such as
shafts 29, i.e. similar to support 22 as discussed above. If the shafts 29 are provided
with an external screw thread, a nut 26 may secure the bracket 12 on the connector
27 similar to the connection described for support 22. The connector 27 may be a metal
part that comprises extensions that are poured into a concrete plate 6 of the filling
element 5.
[0034] A method for applying an assembly 1 according to the invention comprises the steps
of:
[0035] The step of connecting the filling element 5 and the carrier 4 using the bolted connection
11 may comprise one or both of the steps of:
- connecting a connector 27 of the filling element 5 and the carrier 4; and
- connecting the I-shaped beam 7 of the filling element 5 and the carrier 4.
[0036] The method preferably further comprises the steps of:
- placing a bracket 12 of the bolted connection 11 against or near a web 15 of the carrier
4;
- providing a through hole 18 in at least said web 15 of the carrier 4 that is in alignment
with a through hole 17 in said bracket 12; and
- arranging a bolt 20 through the through holes 17, 18 of the bracket 12 and the carrier
4.
[0037] Providing a through hole 18 in said web 15 preferably comprises drilling said through
hole 18 in situ. The bracket 12 may be provided with a through hole 17 prior to assembling
the assembly 1. If the through hole 18 in said web 15 is drilled in situ, it may be
perfectly aligned with the through hole 17 in said bracket 12.
[0038] In order to fill a potential gap between the bracket 12 and the carrier 4, the method
may comprise the optional step of placing one or more than one spacer 16 between the
carrier 4 and the bracket 12.
[0039] The above described embodiment is intended only to illustrate the invention and not
to limit in any way the scope of the invention. Although the shown embodiment is directed
