Description

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.
