TECHNICAL FIELD
[0001] The present disclosure relates generally to a field of electrical building structures
(E-building structures). More particularly, it is related to a floor framework for
a building for housing electrical power equipments.
BACKGROUND
[0002] A concept of modular houses or E-houses has gained a lot of popularity since last
few decades. Such modular houses are generally designed in a container-like structure
which are not only cost-effective but are also easy to relocate. Technical components
of these modular houses may be manufactured at some large and open spaces or factories
and then may be lifted to a desired location.
[0003] Though lot of options are available that design and manufacture such modular buildings/housings,
however majority of these available options faces a challenge in terms pre-requisite
of early designing or pre-fabrication of floor frames. Since placement of different
equipments (any heavy equipments or electrical equipments) may require particular
design of the modular building, the changes in floor framework may be a tedious task,
if performed at a later stage. The floor framework need to be pre-designed as per
the fixing requirements of equipment over the floor framework.
[0004] Another challenge faced by the existing solutions lies in cabled openings that are
provided in the floor framework in order to fix the equipments. In case there is a
need to change the equipment while assembling the modular building, it is extremely
challenging to alter the design of the floor framework. Such a change in the equipment
may lead to lot of redesigning or modifications in the floor framework which is not
only complex task but also leads to lot of financial losses. Additionally, with available
floor structures, any possible extensions or late customizations may not be possible
due.
[0005] Furthermore, in case of currently available steel structures which are used for making
the modular housings and the floor frameworks, application of fire proofing or cable
penetrations during designing and redesigning deteriorates the strength of the steel
floor.
SUMMARY
[0006] Consequently, there is a need for an improved floor framework and a building for
providing easy customization in the design of the floor framework and the design of
the building (for example, providing any late customizations in the floor framework).
[0007] It is therefore an object of the present disclosure to provide a floor framework
and a building for housing electrical power equipment, which mitigate, alleviate,
or eliminate all or at least some of the above-discussed drawbacks of presently known
solutions.
[0008] According to a first aspect of the present disclosure, a floor framework for a building
for housing electrical power equipment is provided. The floor framework comprises
one or more metallic framework elements and one or more CLT (Cross Laminated Timber)
wooden framework elements positioned between the one or more metallic framework elements.
The one or more metallic framework elements are further connected to the one or more
CLT wooden framework elements.
[0009] Therefore, with the proposed floor framework, any late or future customizations in
the floor framework are possible and the proposed floor framework and may allow fixing
of electrical equipments of any design and at any stage. The use of CLT, which can
be to a high degree self-supporting and does not require stabilizing metal beams across
the floor, enables easy attachment of electrical equipment by means of bolting (without
the need of taking the position of any beams into consideration), and also enables
a free positioning of through holes for guidance of cables through the floor.
[0010] In some embodiments, the metal of the one or more metallic framework elements comprises
steel.
[0011] In some embodiment, the floor framework comprises a protective layer which is electrically
non-conductive and may be arranged on a top surface of the one or more CLT wooden
framework elements.
[0012] In some embodiment, the material of the protective layer comprises at least one of
rubber, plastic, pressed hardboard, plywood or surface-finished plywood.
[0013] In some embodiment, the protective layer is attached to the one or more CLT wooden
framework elements through a fixing means comprising at least one of a glue joint,
a screw joint and a bolt joint. In particular, the use of CLT is advantageous when
screw joints and bolt joints are applied, since the CLT reduces the need of a framework
of supporting beams of metal, and since the CLT itself is suitable for such attachment
and can be made self-supporting.
[0014] Therefore, the CLT framework as provided in the proposed floor framework enables
any customization at any point of time while assembling the building.
[0015] The proposed CLT -wooden panel are made from CLT wood which is highly fire resistant
and avoids a need of any separate fireproofing for the floor framework.
[0016] In some embodiment, the one or more metallic framework elements extend around the
one or more CLT wooden framework elements in a shape of a ring-shaped beam.
[0017] Therefore, such combination of metallic framework elements and the CLT wooden framework
elements in the proposed floor framework makes the building more sustainable and provide
better fire resistance.
[0018] In some embodiment, the ring-shaped beam comprises provisions for bolt connections
for arranging a superstructure on top of the floor framework.
[0019] In some embodiment, the ring-shaped beam is provided at at least one end of the one
or more CLT wooden framework elements and each of the CLT wooden framework elements
is connected to and supported by the ring-shaped beam.
[0020] In some embodiment, the one or more CLT wooden framework elements are provided with
one or more openings. With such openings, the low-medium-high electrical equipments
of any design may be easily fixed, which reduces any re-designing or engineering.
[0021] Therefore, the openings (may also be referred as holes) may be made easily in a late
stage with simple wood working tools and the CLT wooden floor framework elements also
allow for easy fastening of the electrical equipments on a whole surface of the floor
framework. Such electrical equipments may be fixed even when the location of openings
gets finalised at a later stage.
[0022] Additionally, with the proposed CLT wooden framework elements any kind of equipment
extensions are easy to execute regarding making new openings and fixing of electrical
equipments.
[0023] In some embodiment, the one or more CLT wooden framework elements are designed to
carry a weight of at least 500 kg/m2 thereon, preferably at least 1000 kg/m2.
[0024] According to a second aspect of the present disclosure, a building for housing electrical
power equipment is provided. The building comprises of a floor and a superstructure.
The superstructure is further comprised by walls and a roof.
[0025] The proposed building becomes universal and may be manufactured for stock usage as
the CLT floor framework elements forming the floor and superstructure may be customised
at any stage.
[0026] In some embodiment, the building comprises of electrical power equipment arranged
on the floor and attached to the floor by means of bolt joints.
[0027] In some embodiment, the electrical power equipment exerts a pressure of at least
500 kg/m2 on the floor.
[0028] In some embodiment, the one or more CLT wooden framework elements form a continuous
sheet defining a floor area of at least 10 m2.
[0029] In some embodiment, the electrical power equipment (104) is a low-medium-high voltage
equipment.
[0030] Advantageously, the proposed floor framework and the building provide an easy to
customize CLT wooden framework which provides an easy assembling and fixing of any
low-medium-high voltage electrical equipments. Such CLT wooden framework elements
in the floor framework is an energy-efficient construction material, where renewable
and recyclable timber is used as raw materials.
[0031] In some embodiments, any of the above aspects may additionally have features identical
with or corresponding to any of the various features as explained above for any of
the other aspects.
[0032] Other advantages may be readily apparent to one having skill in the art. Certain
embodiments may have none, some, or all of the recited advantages.
