Furthermore, the special features, structures or properties can be combined in any suitable manner, as a person skilled in the art can see from this disclosure, in one or more embodiments. Moreover, while some embodiments described herein include some features but do not include other features in other embodiments, combinations of features from different embodiments are intended to be within the scope of the invention, and to constitute different embodiments, as those skilled in the art will understand. Thus, in the following claims, any of the claimed embodiments can be used in any combination.

A first aspect of the invention relates to a logistics building comprising: a. At least one storage space with loading dock suitable for entering and/or loading trucks; b. Office space comprising at least one office; characterized in that the building comprises a load-bearing structure comprising a plurality of load-bearing pillars arranged in a substantially vertical direction, the bases of which are placed in a rectangular pattern on the foundation of the building, these pillars being further connected to each other by means of supporting beams removably attached to

6 BE2022/5686 anchorage points at or near the upper end of each pier, each supporting beam including at least one anchoring point located at each end of the beam, a plurality of corrugated metal roof panels are attached to the supporting beams, these roof panels are so arranged so that the corrugated channels of each roof panel run in the same direction and substantially parallel to at least one exterior wall of the building, to which wall a manifold is securely attached near the top of the wall, the manifold having one entrance end in fluid communication with a network of fire extinguishing fluid, the manifold is further provided with a plurality of exit ends not more than 3 meters apart and not more than 1.5 meters from a wall, pier or beam, each of these exit ends being in fluid communication with a conduit mounted between the roof panels and the supporting beams, this conduit running within a corrugated channel of the roof panels, each conduit further being fitted with fire extinguishing fluid sprinklers at a distance of not more than 3 meters apart and not more than 1.5 meters of a wall, pillar or beam, where the distance between the center line of the pillars is further characterized by their length being a multiple of 1.5 meters.

The network of fire extinguishing fluid pipes that extend along the ceiling of the building provides fire suppression equipment for both the storage and office space.

It is also possible to provide multiple networks of fire extinguishing fluid lines for different areas of the building or even for the same areas of the building.

For example, a newly installed building extension can have its own network of pipes for fire extinguishing fluid or connect to an already existing network.

In this way, the correct pressure and volume of fire extinguishing fluid can be provided.

The distance between the sprinklers offers the advantage of completely covering the building.

The fire extinguishing fluid network is preferably a network of water pipes.

Since the pipes supplying the ceiling sprinklers between the support beams and the corrugated roof elements are installed through the inside of the channels of the corrugated roof elements, those pipes do not reduce the usable space of the building.

Testing of the geometry of the roof elements has shown that each pair of identical channels of corrugated roof sheets should preferably have a mutual distance of 0.25 meters.

This is especially an advantage in combination with the distance between the center lines of the pillars, which distance is a multiple of 1.5 meters, advantageously, and allows a more efficient distribution of the fire extinguishing fluid pipes along the ceiling of the building.

Preferably, the supporting beams are dimensioned to allow a distance between the center lines of the pillars of 12 meters, more preferably 18 meters and most preferably 24 meters.

This way fewer pillars are used,

7 BE2022/5686 while the supporting structure remains sufficiently intact. This has the advantage of reducing the number of potential obstacles, facilitating the movement of people, goods and vehicles within the building.

In a further or different embodiment, the building is provided with at least one electrical network configured for the distribution of electrical power to at least one zone and/or to the office space, at least one water supply network configured for the water supply to at least one zone and/ or to the office space, and at least one refrigerant network comprising at least one indoor unit with one heat exchanger capable of functioning as a condenser and evaporator, the dry anchoring elements being further configured to support these networks. In a further or different embodiment, the supporting beams are dry anchored to complementary dry anchorage points at or near the top of the pillars. The use of prefabricated dry anchoring elements greatly facilitates the assembly, disassembly, repair and scaling up of the building or one of its zones. All electrical, water and refrigerant networks are supported, preferably disconnectably coupled to the dry anchoring elements of the building. This makes mounting, dismounting, repairing and scaling of those networks easier. The use of dry anchorage points offers the great advantage that the structural elements of the building can be safely and easily reused.

In a further or different embodiment, the dry anchorage connection between two construction elements is established by means of complementary anchorage points on each of those elements, each of said anchorage points being defined by at least one hole essentially perpendicular to the surface of the anchor point, and wherein the holes are configured to receive a cylindrical connecting element. Preferably, the holes of each anchor point are oriented in an essentially vertical direction. More preferably the holes are 2% larger than the diameter of the cylindrical connecting elements, more preferably 5%, 7%, most preferably 10% larger than the diameter of the cylindrical connecting elements. In this way, the structure of the building can advantageously withstand thermal expansion/contraction of at least one of its structural elements, some ground instability, earthquakes and significant wind forces.

8 BE2022/5686

In a further embodiment, the upper end of each pier has four anchoring points. In this way, up to four beams can be anchored to the top of a pier. This allows the same type of pier to be used in the center of a storage area, along a wall and/or a corner, greatly reducing logistical complexity during building assembly.

This type of pier further allows easy expansion of the building, as new beams can simply be joined to the beams that previously defined the building's outer perimeter. Preferably, two of the anchor points of each pier are located at a lower level near the top of the pier, with the anchor points at the lower level being at the same height. This allows four anchorage points on top of a pier without having to increase the cross-section of that pier. This offers the advantage that as much of the usable area of the building as possible is retained.

In a further or different embodiment, each pier has at least one additional anchorage point between its base and its top. This at least one additional anchor point makes it cost-effective to add multiple floors to the building, greatly increasing the scalability of each room of the building.

In a further or different embodiment, each supporting beam comprises at least one anchoring point located at each end of that beam. Optionally, at least one of the beams includes at least one anchor point between each end of that beam. Preferably, each beam placed along the length of the ceiling and walls of the building includes one anchor point between each end of that beam. More preferably, each beam placed along the length of the ceiling and away from an exterior wall of the building includes two anchor points between each end of the beam. In this way it is possible to reduce the number of pillars while still maintaining sufficient support for the roof, the sprinkler network and the electricity grid and lighting.

In a further embodiment, the roof of the building has a slope determined by a plurality of sloping shims placed at the anchorage points between the pillars and the beam that supports the roof elements.

This allows the number of types of beams required during building assembly to be reduced, which is an advantage in reducing the complexity and costs of beam production, distribution and assembly.

9 BE2022/5686

In a further embodiment, the pillars have a hollow centerline containing a pipe for draining rainwater to a drainage system under the floor of the building. This allows the number of pipes attached to each pier to be further reduced, leaving more usable space around that pier. Another very beneficial effect is the elimination of most of the work required to install drain pipes, since most of those pipes are already part of the piers. In combination with a sloping roof, the pillars according to the current embodiment make it possible to collect rainwater and direct it like a funnel to the mouth of the pipe at the top of a pillar, after which the water flows through that pipe into a drainage network under the floor of the building could fall down. Preferably, the upper end of the pipe is complementary to the opposite end of the pipe at the lower end of the pier. This offers the advantage that multiple pillars can be stacked, while the water drainage capacity of the pillars is retained.

In another or further embodiment, at least one of the storage areas is equipped with a mezzanine, the mezzanine comprising at least one reinforced concrete slab configured to be dry anchored to other such slabs and/or beams and/or pillars. Preferably, each plate is rectangular and further equipped with anchoring points. The anchorage points are most preferably located at opposite ends of the plate, with the two remaining adjacent sides configured to allow two side-by-side plates to be joined by means of adhesives, preferably adhesives based on silicone or epoxy. The mezzanine is preferably located above the loading dock. The ability to easily add a mezzanine makes it possible to make optimal use of the space cost-effectively.

In another embodiment, the building further comprises: a. At least one renewable energy element installed on the roof; b. At least one thermoelectric module with means for the storage and supply of electrical energy, means for the storage and supply of water and a heat pump system, where the means for the storage and supply of energy are detachably coupled to at least one on the roof installed renewable energy element, the public electricity grid and at least one electricity grid of the building, with the means of water storage and supply disconnectably connected

10 BE2022/5686 are connected to at least one water network of the building, whereby said water network is at least a fire extinguishing fluid network, to the heat pump system and to a water supply, and where the heat pump is detachably linked to at least one refrigerant network of the building.

The roof-mounted renewable energy element is preferably at least one wind turbine, and preferably at least one solar panel. The at least one thermoelectric module in combination with the at least one renewable energy module offers the advantage that the building can be self-sufficient in terms of electrical energy and heat regulation. The at least one thermoelectric module further provides a buffer volume of water, which volume of water at least meets the fire extinguishing requirements of the building. Each thermoelectric module is preferably contained in a container. This offers the advantage that the thermoelectric modules can be deployed quickly and easily, while defective/redundant modules can also be easily removed or replaced. In this way, the scaling up of electrical energy, cooling/heating and water supply is made easier and faster.

However, it is clear that the invention is not limited to this application. The building according to the invention can be used for other industrial applications, such as factories, farms, but also for non-industrial applications such as schools or exhibition halls.

The invention is further described by the following non-limiting examples which further illustrate the invention, and which are not intended to limit the scope of the invention and should not be construed as such.
