Description

Bathroom module and method for making a bathroom module

[0001] The invention is directed to the bathroom module according to the preamble of claim 1.

The invention is also directed to the method according to the preamble of claim 13 for manufacturing a bathroom module.

[0003] One of the trends in construction is that more and more modules are used in construction, because if done in the right way, it can be a cost-effective way to transfer construction work from construction site conditions to a factory-like environment, to manageable dry, well-lit and even temperature conditions. There are different requirements for the modules, such as the modules must be dimensionally accurate and keep their shape.

[0004] Modules can have different levels of readiness. Precast concrete elements are the most typical modules with a low degree of completion, as are the various base slabs on which walls are built on the construction site. Modules assembled from concrete elements on the construction site are difficult to install, and in practice they cannot be waterproofed or coated in advance, but a considerable amount of work remains to be done on the construction site. This especially applies to bathrooms and similar wet rooms. Pouring the base of the module and building the walls on top of the poured floor takes time, and the structure has several seams of different materials. In addition, the modules are exposed to the stresses of the weather during transport and installation.

N [0005] L lift users — wish for — stone walls in the bathroom, because

In N's imagination, it is associated with high quality and a long-lasting structure. - In addition, they also have many useful technical properties: insulation,

N bearing capacity, non-flammability, dimensional accuracy, etc. For bathrooms

E 30 — the walls of the modules are typically not concrete walls. ©

O

[0006] The purpose of the invention is to raise the state of the art prevailing in the field by presenting a bathroom module that minimizes the problems of the known technology.

[0007] The aim of the invention is to provide a bathroom module that enables efficient and reliable, fast-scheduled bathroom construction, such as for example hotel construction or apartment building construction, where there are many similar bathrooms in one construction site.

[0008] The aim of the invention is also to provide a method by which a bathroom module according to the invention can be produced in an efficient and simple way.

[0009] The — objectives — of the invention are achieved — mainly — in the manner presented in more detail in independent patent claims 1 and 10, as well as other claims.

[0010] One embodiment of the invention is a bathroom module, which comprises — cast structure base plate that forms the floor and at least three walls, in which building technical components are arranged inside the cast structures, - inside the base plate are — arranged — drainage means — and floor heating elements, - inside the wall are arranged electrical boxes, electrical cables and /or electrical piping — and/or the provisions of the previous ones for electrification, as well as water pipes and/or water pipe penetrations and/or the provisions of the previous ones for bringing water to water fixtures,

S where the mentioned walls and base plate are one casting. a [0011] In the context of this invention, bathroom refers to a space that is intended and suitable for people to wash themselves and take care of other = personal hygiene. Typically, the bathroom has

A sink and shower, shower cubicle as a functional element for washing

O and/or bathtub, and possibly a toilet seat or similar. As one

A special feature of bathroom construction is that in most countries — building regulations require a structure that prevents water from entering other rooms from the bathroom, other than through the drain. In practice, this means a multi-layer solution for surfaces, of which at least one of the layers is a waterproof layer, the so-called waterproofing layer. The special purpose of the bathroom module that is the subject of the invention is to serve construction, where the goal is to efficiently make compact-sized structures that can be conveniently moved during the construction phase.

[0012] The terms used in connection with this invention mean the following: — - Building technical components means components required for heating, incoming water and drainage and electrification in connection with this invention.

Ventilation can also be considered a part of this, but the components of ventilation can be built into a suspended ceiling or other roof structure, which does not necessarily have to be included within the protection circuit of the essential bathroom module defined by this invention. - water drainage means in the context of this invention means a floor well, a line well in the floor, a water collection trough, a hole in the floor for drainage or a similar structure that leads the water on the floor away and on to the drainage section possibly connected to it, - floor heating elements — means this application (in connection with the usual one used for heating the bathroom floor an arrangement whose purpose is partly to keep the floor feeling comfortably warm to walk on with bare feet, but partly also to keep the structures dry and to dry the bathroom after use. In general, either electric heating is used for the purpose, in which case the heating cable is inside the base plate, or alternatively

N water-circulating floor heating, whereby hot water piping circulates inside the floor. = An alternative way to arrange floor heating is to use an infrared or similar radiation heater or a fan arranged in the space, with the help of which the floor - can be heated and dried with the help of warm air. = 30 —- In the context of this invention, cast structure means such a structure,

O which is created from the material by casting and removing the casting mold around the structure

O after the casting has solidified, when the casting surface remains the cast body

O as the external interface. The components placed in the casting mold before casting, a possible support structure, such as support reinforcement or a support structure made of similar other reinforcement, remain inside the cast-structured body. Injection molding is also a technique available, so an injection molded part is considered to be a casting / casting. In particular, it should be noted that pieces with different shell structures are not considered cast structures, even if material could be cast inside the shells. The shell refers to the support structure that remains as the surface of the formed piece. - Inside the wall of the bathroom module, electrical boxes, electrical cables and/or electrical piping and/or provisions for the former are arranged for electrification.

Bathrooms typically have lights, in addition to a ceiling light, for example, in connection with a mirror cabinet, and sockets for using or charging electrical devices, such as a hair dryer, shaver, electric toothbrush. A more aesthetically pleasing and finished bathroom is created by installing the necessary cables and electrical boxes inside the wall as flush mounts, compared to the situation of using — electrical cables or switches and sockets drawn into the finished surface. In building the bathroom module according to the invention, the goal is to have the majority of the work done at the factory, in which case at least the mentioned provisions are made in the wall of the bathroom module, even if the actual wires and their connections are only made at the construction site. - Like the electricity, also the water pipes and/or water pipe penetrations and/or the provisions for the former to bring water to the water fixtures are arranged inside the wall, i.e. they are built to the necessary readiness before the bathroom module is poured and thus built in the factory.

[0013] Cast construction base plate forming the floor and at least three

S walls are one casting. In this way, the bathroom module can be efficiently < manufactured = in such a way that the majority of the work can be done €industrially in factory conditions. Thanks to this feature, fixing of separate walls to the base plate is avoided, making it possible to design the structure to be very = 30 — strong and rigid in relation to the mass of the bathroom module. Into the mold

O can be pre-made different shapes that repeat exactly the same

O for every casting made using the mold. For example

It is possible to make exactly the right inclinations (e.g. required by a tiling robot) to the base slab, i.e. the floor, to direct the water to the drainage means. As another example, we can mention the flush that can be done in the doorway, which enables accurate and quick installation of the door / frame. Furthermore, the one-piece casting makes it possible to waterproof the entire required area without having to waterproof the corner 5 between the wall and the floor only after the walls have been attached.

[0014] The mentioned walls and base plate of the bathroom module are cast as a single casting from a structural material suitable for the purpose, such as concrete, a concrete derivative or a composite material, such as — fiber-reinforced polymer. With this, the end-users want a stone structure or a structure that feels like it, which can be tiled or coated with the desired surface material. The mentioned structural materials are typically very sound-insulating, sturdy-feeling and fire-resistant materials, with the help of which the necessary classifications required by building regulations can be achieved. In addition to conventional structural concrete, possibly suitable materials include, for example, foam concrete, silicon oxide airgel, and product names such as Betolar. According to an advantageous embodiment, the structural material is itself a waterproofing material.

[0015] According to one embodiment of the invention, the bathroom module comprises at least three cast walls and one other cast wall or four cast walls. In terms of the efficiency of bathroom module manufacturing, four cast walls are probably the most efficient production method, which would allow a large number of bathroom modules to be made as quickly as possible. However, in some cases different

For interior or architectural reasons, the fourth wall of the bathroom module = can be manufactured in a different way than by casting the other three walls in the same connection as a, without losing much of the production and technical advantages of the invention. In some cases, for example, = 30 can be used — a glass wall, a lightweight wall, or a bathroom module is installed

Or else — against a water-insulated wall, in which case only a joint seam

O waterproofing is ensured. 3

[0016] According to one embodiment of the invention, the base plate of the bathroom module and at least three walls are reinforced or otherwise supported from the inside of the casting, such as a braced cast structure. The purpose of the support reinforcement is to stiffen the structure so that it is suitable for its intended use and in such a way that the factory-made bathroom module can be transported to the construction site and installed in place. Support reinforcement made of concrete steel with concrete is a well-known and functional combination, but with other materials, concrete steel is not necessarily the most suitable material. In this case, something else, such as a support grid, may be the most effective solution.

[0017] Preferably, the support reinforcement or other support comprises corner supports that extend inside the casting both inside the base slab and inside the wall to a distance from the corner between the base slab and the wall. The special purpose of this feature is to provide such rigidity to the structure that the walls and — base plate cannot move in relation to each other. This kind of movement between the walls and the base plate is particularly harmful in terms of waterproofing, because the waterproofing must not tear at any point in the production, installation or use chain. — Waterproofing — must be — waterproof — from manufacture to the entire planned service life of the bathroom module. Therefore, a structure that allows the corner between the base plate and the wall to "open"? movement and contributes to the tearing of the waterproofing, is harmful in terms of the longevity of the waterproofing. This kind of harmful movement can be prevented with the help of sufficiently robust corner supports.

[0018] Advantageously, the bathroom module comprises a ceiling that is a separate piece

N as mentioned base plate and walls. In terms of manufacturing, the structure is open from the top

N is useful because it allows convenient accessibility to various operations required in - manufacturing =. These can be, for example

The use of N tiling robots in tiling the walls and floor of the bathroom module

E 30 — and the use of various lifts is easy when the accessories and components to be installed can be lowered directly into the interior of the bathroom module with a crane

N without having to carry them through the doorway. It's still in the bathrooms

N often lowered interior ceiling, which is lower than other rooms

N roof. Different ventilation = systems can be installed in the space between the lowered inner ceiling and the actual ceiling height, such as a heat recovery system or other air conditioning or ventilation equipment. In the bathroom module according to the invention, the ceiling element can be manufactured as a separate work step elsewhere or at the same time as the interior of the bathroom module is being built. When the interior is ready, the roof element forming the roof is installed. The ceiling element can be installed between the walls and/or on top of the walls. Although the height of the wall of the bathroom module essentially determines the interior height of the bathroom, the joint between the ceiling element and the walls of the bathroom module makes it possible to adjust the total height of the bathroom module by means of elevation pieces such as elevation strips. In any case, the seam between the walls and the ceiling of the bathroom module must be built as required by the requirements, but there are a considerable number of different implementation options for this, which will not be discussed further here.

[0019] According to an advantageous embodiment, the floor and walls of the bathroom module are waterproofed with waterproofing at the factory. Making waterproofing is one of the critical work steps in the production of a bathroom, which should be done in a way that meets the requirements and with as much uniformity as possible. Industrially, waterproofing at the factory during the production phase is one way to achieve uniformity. In a factory-like process, it is easy to determine, for example, the sufficient drying times of waterproofing materials and according to the instructions, or the sufficient cleanliness / dust-freeness of the production facilities to ensure adhesion of the materials. When manufactured industrially as factory work, it is easy to ensure that the floor and walls of the bathroom module are waterproofed at least — 25 — to the — height — required by the building regulations — from the floor or €enough

O to the distance from the water point. a [0020] Preferably, one or more walls of the bathroom module are - a wall between the apartments or a load-bearing wall. Different spaces in the building, such as different = 30 — apartments, apartment and corridor, apartment and movable storage or apartment

A number of different building regulations apply to the walls between O and the technical space.

O When the bathroom module according to the invention has at least three walls

O cast structures, they make it relatively simple to meet the requirements for the walls between the above-mentioned rooms. Therefore, from the point of view of the overall economy of the construction, it may possibly make sense to make one or two of the walls of the bathroom module a little sturdier, so that it meets the building regulations for the case in question.

[0021] According to one — embodiment — the bathroom module is a partial product, whereby the furniture, such as water fixtures and/or other furniture, is installed during the construction phase on the construction site. According to another embodiment, the bathroom module is factory ready so that during the construction phase on the construction site, the bathroom module can be attached to the structure and the interfaces — drainage, water pipes, ventilation ducts and electricity can be connected to operational condition. In practice, therefore, a certain minimum delivery scope can be defined, which is considered to be economically reasonable and a sufficiently large part of the construction work can be done at the factory. At the other extreme, the degree of readiness is the so-called A "Plug & Play" type of solution, where a completely finished — bathroom module is delivered to the construction site, installed in place and connected to the drainage, water pipes, ventilation duct and electricity.

[0022] According to another embodiment, the bathroom module comprises. in the area of the base plate and walls, attachment points with which — the bathroom module or casting can be lifted and/or turned around an axis and/or attached to the surrounding structure during construction. During the production phase and later during the transportation and installation phase, it is convenient if the bathroom module already has such attachment points that facilitate lifting, turning and moving. In this case, you don't need to start arranging different lifting ropes or the like around the structure, but you can

N the measures in question to be carried out with the intended purpose and for the product and

N with safe — means. In the context of this invention, the attachment points therefore mean such structures or structural details with the help of which

The N bathroom module can be lifted, turned around an axis and/or

E 30 — can be attached during the construction phase — to the surrounding structure, — which makes the automation of e manufacturing easier. They can be, for example

N lugs, dodges, gaps or the like.

[0023] The invention — applies = also to a method — for the manufacture of a bathroom module, which bathroom module comprises a cast-structure base plate forming the floor and at least three walls, in which case technical building components are arranged inside the cast structures, - drainage means are arranged inside the base plate — and floor heating elements are arranged, - inside the wall are arranged electrical boxes, electrical cables and/or electrical piping and/or provisions for the former for electrification, as well as water pipes and/or conduits for water pipes and/or provisions for the former to bring water to the water fixtures, — the method includes the following steps: - preparing the inner mold for casting, the inner mold comprising the negative of shapes corresponding to the interior raw surfaces of the bathroom , - — the inner mold is coated — liquid-tight — with a casting release material, — such as a waterproofing fabric or other similar waterproofing, — - drainage means and any drain connected to it are attached to the inner mold, and they are supported for pouring into the inner mold, - electrical boxes and electrical cables and/or electrical piping are attached to the inner mold and or charge components for electrification, - water pipes and/or water pipe feedthroughs are installed in connection with the inner mold and/or — the provisions for the former to bring water to the water fixtures, - support reinforcement or other supports remaining inside the casting are installed around the inner mold, - cast or sprayed in the casting, - the casting is allowed to harden until it has sufficient strength reached, after which — 25 — the mold or molds are removed,

O - the bathroom module is built to the desired level of readiness. © [0024] In practice, the interior mold is used to create a bathroom module

I the raw surfaces of the interior, the floor with the necessary inclinations and the walls ready for tiling. > 30 — The inner formwork also acts as a kind of installation jig, to which = building technical components are attached. First, a casting release material is installed on top of the inner mold, which is preferably a waterproofing fabric or other similar waterproofing. The waterproofing fabric is sealed to make it watertight. Building technical components can be advantageously attached to the inner formwork in their correct places, for example by means of screws, when the inner formwork is prepared as an installation jig-type solution, with all the holes and attachment points required for installation ready. After the building technical components, the most suitable ready-made structure is raised around the inner mold — prefabricated support reinforcement, which is placed at the planned distance from the surface of the inner mold, i.e. after casting, from the inner surface of the bathroom module. Alternatively, the support reinforcement is lifted into place before the outer formwork is installed. Preferably, the casting takes place in such a way that the bathroom module is formed — upside down compared to its normal use position, i.e. the floor is facing up, so that the sealing surface of the casting material — fits most conveniently against the inner mold.

[0025] After the casting mold and pre-preparations are completed, the cast mass is cast or injected. Here, a two-sided inner mold — outer mold solution can be used, or alternatively, a one-sided injection molding technique, in which — a suitably rigid and quickly solidifying casting material is sprayed onto the surface of the inner mold. After casting, the casting is allowed to harden until sufficient strength has been achieved, after which the temporary fastenings of building technical components made for casting can be removed and the casting mold or casting molds are removed.

[0026] Other additional characteristic features of the invention are apparent from the accompanying patent claims and the following explanation of the embodiments of the figures.

[0027] In the following, the invention and its operation are explained with reference to the accompanying diagrammatic drawings, in which — Figure 1 schematically shows an embodiment of the — bathroom module according to the invention,

- drainage means 2 and floor heating elements 3 are arranged inside the base plate 11, - electrical boxes 40, electrical cables 41 and/or electrical piping and/or provisions for electrification are arranged inside the wall, as well as water pipes 5 and/or conduits for water pipes and/or provisions for bringing water to water fixtures , in which case the mentioned walls 12 and the base plate 11 are one casting 10. Preferably, the mentioned walls 12 and the base plate 11 are cast as a single casting — from a structural material suitable for the purpose, such as concrete, a concrete derivative or a composite material, such as — fiber-reinforced polymer. Figure 1 illustrates how the bathroom module 1 comprises at least three cast walls 12. One of the walls (not shown in Figure 1) can be of a different structure, or alternatively the bathroom module can comprise four cast walls 12.

[0029] Figure 2 shows schematically a cross-section of a bathroom module 1 according to one embodiment, which comprises a base plate 11 that forms the floor and at least three walls 12 of cast construction, where building technical components are arranged inside the cast structures, - drainage means 2 are arranged inside the base plate 11, and — floor heating elements 3, - electrical boxes 40, electrical cables 41 and/or electrical piping and/or provisions for the former for electrification are arranged inside the wall, as well as water pipes 5 and/or conduits for water pipes and/or provisions for the former to bring water to the water fixtures, in which case the mentioned walls 12 and the base plate 11 are one casting = 25 10. The waterproofing 8 extends up to the walls 12 in accordance with building regulations. & = [0030] Figure 2 shows an embodiment in which the bathroom module © comprises a roof 7, which is a different piece than the mentioned base plate 11 and walls 12.

I A ventilation system 9 is arranged inside the ceiling. Figure 2 also shows > 30 — an embodiment for the connection between the ceiling element forming the ceiling 7 and the bathroom module = walls 12, the ceiling is fitted inside the walls 12 as a so-called = lowered ceiling, whereby the walls 12 extend higher than the ceiling 7

N lower surface. In this way, it is also possible to adjust the total height of the bathroom module 1 to the desired height with the help of heightening pieces 70, such as heightening strips.

In a solution according to an advantageous embodiment, the height of the wall 12 of the bathroom module 1 essentially determines the interior height of the bathroom. In this case, the molded walls 12 continue vertically up to the interface of the roof 7. — In some special cases, however, there may be, for example, windows or other skylights, glass bricks, etc. at the top, but even then the cast wall extends up to the window structures.

[0031] Furthermore, Figure 2 shows an embodiment in which — the base plate 11 of the bathroom module 1 and at least three walls 12 are reinforced with support 6 or otherwise supported from the inside of the casting, such as a buttressed casting structure. In Figure 2, the support reinforcement 6 is shown for the sake of clarity as only a few support bars 6 parallel to the picture plane, but it is understandable to a professional in the field that there are at any given time the number of support bars 6 required for the strength of the structure and they are both longitudinally and transversely with respect to the perspective of Figure 2. Figure 2 also shows an embodiment in which the support reinforcement 6 or other support comprises corner supports 61, which extend inside the casting 10 both inside the base plate 11 and inside the wall 12 to a distance from the corner between the base plate 11 and the wall 12. The function of these corner supports — is to strengthen the area of the corner between the base plate 11 and the walls 12 and to prevent the casting 10 from breaking as described earlier. Preferably, one or more walls 12 of the bathroom module 1 is a wall between the apartments or a load-bearing wall.

[0032] Furthermore, figure 2 shows how one embodiment

According to N, the bathroom module 1 comprises in the area of the base plate 11 and the walls 12 = attachment points 62, with the help of which the bathroom module 1 or the casting 10 can be lifted and/or turned around an axis and/or attached - during the construction phase to the surrounding structure, such as the frame of the building. = 30 — The purpose of the attachment points 62 is therefore to facilitate construction

O automation and make bathroom module 1 or casting 10

O suitable for automation. As an example of a job that can be automated

O can be mentioned tiling, which is demanding by hand and requires considerable precision from its creator. The ceramic tiles that make up the final interior surface of the bathroom are attached to the floor/wall with mortar and sealed. Doing this work step neatly and always in the same way in construction site conditions is by no means self-evident. The mortar used for fixing the tiles must be applied to each spot with exactly the same layer thickness and viscosity. For example, the position of the mortar spreading comb and the residence time of the mortar in the mortar bucket are factors that are prone to change constantly in hand-made tiling. If the tiler cannot control and standardize these, the tiles will be placed at different heights from the surface. Horizontal of the tiles — is also very accurate in relation to its position so that the tiles' seams do not look crooked. Such tiling can also be automated, in which case the tiling always takes place in the same way, but using a tiling robot in construction site conditions is usually not profitable. In the industrial hall, this work step or function can be automated. In this case, however, it is most advantageous if it is to be tiled — the piece can be turned so that the tiling always takes place horizontally.

The automation of the production of the bathroom module 1 according to the invention is facilitated if the casting 10 is arranged, preferably already in the initial stage and/or as part of the support reinforcement 6, attachment points 62, from which the casting 10 can be grasped and it can be turned to the required — position.

[0033] As previously explained, the floor 11 and walls 12 of the bathroom module 1 are waterproofed with waterproofing 8, preferably already at the factory. According to the advantageous embodiment, the floor 11 and walls 12 of bathroom module 1 are = 25 — waterproofed with waterproofing 8 at least as required by building regulations

S at a height from the floor 11 or at a sufficient distance from the water point 5. a [0034] The following presents a method for manufacturing the - bathroom module 1 shown in figures 1 and 2, which bathroom module 1 comprises = 30 - cast construction base plate 11 forming the floor and at least three walls

[0035] According to one embodiment, the outer mold (not shown in the figures) is prepared for casting, - the casting mass is poured between the inner mold and the outer mold, - the casting mass/mould is vibrated so that the casting sits tightly in the mold and any — 25 — air bubbles escape. Alternatively, the method is performed as

O that the outer formwork is the actual mounting base for building technical components and = the inner formwork is only for creating the interior shape of the bathroom. In this case, the installations described earlier © are made in the outer formwork and the outer formwork is used

I as an installation jig. Preferably, the support reinforcement is prepared as a whole > 30 — clearances, after which the support reinforcement 6 is lifted into place before the outer formwork = is installed. Alternatively, if the outer formwork first technique is used, = the support reinforcement is installed before installing the inner formwork. Both of them

It is not recommended to install the support reinforcement after the N forms have been installed, because the support reinforcement can easily damage the — installed — building technical — components. = This = is why the installation sequence must always be planned on a case-by-case basis.

It should be noted that only a few of the most advantageous embodiments of the invention have been presented above. Thus, it is clear that the invention is not limited to the embodiments presented above, but can be applied in many ways within the framework defined by the accompanying requirements. The features presented in connection with different embodiments can also be used within the framework of the basic idea of the invention in connection with other embodiments and/or combine different entities from the features presented, if desired and the technical possibilities for this exist.
