Description

The field of technology

The subject invention relates to the design of the ceiling of a clean room, that is, to the technical solution of the components of that assembly, and to the procedure for its execution.

The field of technology to which the present invention relates is designated by the International Classification of Patents with E04B9.

Technical problem

The technical problem that is solved by the present invention relates to the design of the clean room ceiling, and consists in defining such technical solutions of the associated components of the clean room ceiling, the design of which enables the construction of the clean room ceiling by such a procedure that, in relation to the known state of the art, represents a more favorable solution according to all criteria, and above all in terms of simplicity and precision as well as duration, rationality, and transparency of the implementation of the procedure.

State of the art

The term clean room means a space in which a minimized and controlled level of intake, generation, collection and retention of particles (contaminants), such as dust, airborne microbes, and aerosol particles, is achieved. The level of contaminants is expressed by the number and size of allowed particles per volume of air, which is used to classify clean rooms intended for use in pharmaceutical, biotechnological, medical, chemical, food, electronic, dairy and other industries sensitive to environmental pollution.

A clean room is actually a space of a certain size and shape that is bounded by walls with corresponding openings for doors and possibly windows, as well as a floor and a ceiling that should all be designed in such a way as to achieve the required parameters in that limited space, whereby, due to the complexity, special attention is paid to the performance of clean room ceilings.

Ceiling solutions for clean rooms belong in a broader sense to the group of commonly called suspended ceilings, where they are practically regularly and almost exclusively not a construction-derived ceiling of the room, but a single surface of a certain content, purpose and performance is formed under that construction ceiling at a certain distance.

In the design of clean room ceilings according to the known state of the art, in addition to the requirements regarding achieving the ceiling's impermeability between the clean room and the surrounding space, there are also a number of ceiling functions that are realized by associated components that are installed as integral elements of the ceiling.

As the supporting structure of the ceilings of clean rooms according to the known state of the art, practically as in the case of usual suspended ceilings, a network of supporting profiles, longitudinal (1.1) and transverse (1.2), which are, as a rule, placed at right angles to each other and connected by appropriate joints ( 1.3), in which way they form one grid with openings (1.4) of appropriate sizes, for example as in Figure 1.

The grid of load-bearing profiles formed in this way, which forms the skeleton of the ceiling, is suspended from the building ceiling with the appropriate number and types of suspensions (2.1).

Individual components of the clean room ceiling are placed in the appropriate number of individual openings (1.4) of appropriate sizes in the load-bearing ceiling grid, while any unused and unfilled openings are hermetically sealed in the appropriate manner in order to achieve impermeability between the space of the clean room, i.e. under the ceiling and the surrounding area , so the one above the ceiling.

The most common components that are installed in the openings in the load-bearing ceiling grid are panels, filter units, lighting fixtures and elements for air distribution.

According to the known state of the art, the construction of cleanroom ceilings, as well as the mere investment of components in the corresponding openings (1.4) of the intended sizes, is a complex and demanding task, the performance of which regularly consumes a lot of the contractor's time, which results from the need to perform a series of actions, which all together results in the expenditure of significant time and thus financial resources.

As is well known, the ceiling of clean rooms is usually constructed in such a way that hangers with suspended load-bearing elements are placed, and ceiling panels are hung and fixed on them, after which a series of actions are performed, such as leveling each panel separately, cutting openings inside the panels, placing the reinforcement inside the panel, fixing the components with screws.

The disadvantage of performing and installing clean room ceilings is not only the complexity and long duration of installation, but also the need for leveling and very often subsequent changes or modifications of individual ceiling components.

The patent literature, as an extensive part of the known state of the art, contains numerous different solutions that were created in attempts to solve the above-mentioned technical problem, and are mainly reduced to variations of the previously described known technical solutions, but none of these solutions are even close to being achieved solving the previously mentioned technical problem as far as possible and satisfactorily.

Tako, poznato stanje tehnike sadržano u patentnoj literaturi, primjerice prema patentnim spisima WO98/17141, EP0202110, DE3812094, DE29704428, US6158186, US5993311, DE3708646, US5865674, US5794397, US5454756, FR1486186, US4860420, US3360910, US5794397, JP202012912, obuhvaća rješenja koja predstavljaju only a partially successful attempt to solve the technical problem mentioned above, since it is about inadequate technical solutions of the component components of the supporting grid of the suspended ceiling, and thus a more complex structure as well as ways of connecting the longitudinal and transverse supporting profiles, which results in less favorable ceiling execution procedures.

With all clean room ceiling solutions according to the state of the art, the unsolved problem is the performance of individual components of the ceiling grid, which is not adequately subordinated to the achievement of a more favorable assembly procedure, as a result of which the ceiling assembly procedures are complex and time-consuming, which is ultimately reflected in the high price of performing clean room ceilings .

It is not known that the known state of the art, including the patent literature, would contain complete solutions to the indicated technical problem in a broader sense, and especially not in relation to all the aspects mentioned above in the technical problem.

The essence of the invention

The solution to the aforementioned technical problem was achieved by the technical solution according to the invention, which is based on the unique design of the relevant component parts of the clean room ceiling, which enables the implementation of a simpler, more precise, higher quality and more rational process of creating the clean room ceiling.

The essence of the invention is reflected in the fact that such a performance of the constituent parts of the ceiling and their functionality as built-in components within the load-bearing ceiling was achieved that a number of possibilities were created for simpler and faster execution of the ceiling with assembly at the place of execution with the use of minimal techniques and tools, the result of which is easier assembly and dismantling the ceiling of the clean room.

The essence of the technical solution according to the invention consists, first of all, in the fact that multi-purpose multifunctional bearing profiles, both longitudinal and transverse, (pictures: 3.A and 3.B) of corresponding lengths L (3.6) were conceived as bearing profiles, which were made as that their cross-section is in the form of a complex geometric figure, in which way they serve as multifunctional constituent elements of the clean room ceiling grid.

This was achieved in such a way that the cross-section of multifunctional (3.A., 3.B), longitudinal and transverse, supporting profiles of corresponding length L (3.6) is in the form of a complex geometric figure, which is formed by the central (3.9) longitudinal channel in the form of a rectangle of height Hp (3.8), from each of the lateral vertical sides of that central (3.9) longitudinal channel approximately at the height of Hp (3.8), one lateral longitudinal channel (3.3) in the shape of a rectangle, which are without vertical outer sides, is derived. that is, the rectangles are open laterally to the outside.

In addition, from the upper side of the central (3.9) longitudinal channel, an upper (3.2) longitudinal channel in the form of an open rectangle with an opening towards the outer, upper, side of the multifunctional (3.A., 3.B), longitudinal and transverse, supporting profile. Below the central (3.9) longitudinal channel, a lower (3.7) longitudinal channel is made in the shape of a rectangle, open to the outside at the bottom, and this space is closed with a transparent cover (3.4) and a light fixture (3.5) is placed in it.

In addition, from the sides of the lower (3.7) longitudinal channel, one round (3.1) longitudinal channel in the form of a roller was made, with a longitudinal opening laterally outwards, whereby on the lower edges of the longitudinal openings laterally outwards each of the two round ( 3.1) of longitudinal channels, continue the support surfaces (3.10) of multifunctional (3.A., 3.B), both longitudinal and transverse, load-bearing profiles.

Cross-sections of load-bearing lamellas, supporting (4.A., 4.B), as well as suspended (5.A., 5.B), are in the form of a specific complex geometric figure, which in the case of supporting (4.A., 4B) supporting lamellas, length Lp(4.6), form the appropriate geometric figures of the boundary (4.4) and supporting (4.5) arm, between which there is a segment with a supporting surface (4.7), as well as a supporting segment with a supporting surface (4.3), and a cylindrical joint (4.1) with pivot axis (4.2).

In a similar way, the cross-section of the suspension (5.A., 5.B) lamella, length Lo (5.6) is in the form of a complex geometric figure, which is formed by the corresponding geometric figures of the boundary (5.4) and supporting (5.5) arm, between which is the segment with the bearing surface (5.7), as well as the support segment with the support surface (5.3), and the roller joint (5.1) with the pivot axis (5.2).

In the case of a supporting (fig. 4.A and 4.B) load-bearing lamella, the force of gravity acts in the axis of gravity (4.8) in the direction (4.10) with the arm (4.9) between the pivot (4.2) and the axis of gravity, and in the same way in in the case of the suspension (5.A., 5.B) load-bearing lamella, the grip of gravity acts in the axis of gravity (5.8) in the direction (5.10) with the arm (5.9) between the pivot (5.2) and the axis of gravity.

The external shape and dimensions of the roller joints, both supporting (4.1) and suspension (5.1), load-bearing lamellas, in relation to the shapes and internal dimensions of the round longitudinal channel (3.1), i.e. the capsule of the roller joints of multifunctional load-bearing profiles, ( 3.A., 3.B) so mutually coordinated that, in the first place, the possibility of investing roller joints, both support (4.1) and suspension (5.1), load-bearing lamellas, in round longitudinal channels (3.1), i.e. capsules, roller joints of multifunctional load-bearing (3.A., 3.B) longitudinal and transverse, which is carried out in such a way that first the roller joints (4.1) are supported (4.A., 4.B), and likewise (5.1) are suspended (5. A., 5.B), load-bearing lamellas, from the axial side of the multifunctional (3.A., 3.B), longitudinal and transverse, load-bearing profiles are axially inserted into the corresponding capsules (3.1) of the multifunctional profiles, how to connect the multifunctional (3.A., 3.B) load-bearing profiles with load-bearing lamellas, supporting (4.A., 4B) and suspension (5.A, 5B), respectively o are formed by assemblies, assembly (6., A., 6.B) of multifunctional profile and supporting load-bearing lamellas, as well as assembly (7.A., 7.B) of multifunctional profile and suspension load-bearing lamellas.

The aforementioned mutual compatibility of the shape and dimensions of the load-bearing lamellas in relation to the shapes and internal dimensions of the round longitudinal channel (3.1), i.e. the capsules of the roller joints of the multifunctional load-bearing profiles (3.A., 3.B), also creates the possibility of free rotation without resistance of the roller joints supporting (4.1) and suspension (5.1) load-bearing lamellas around pivot axes (4.2) support (4.A., 4.B) and pivot axes (5.2) suspension (5.A., 5.B), load-bearing lamellas , inside the capsules of roller joints (3.1) multifunctional (3.A., 3.B), longitudinal and transverse, bearing profiles.

In the assembly (6.A and 6.B) of the multifunctional profile and the supporting load-bearing lamella, as well as in the assembly (7.A., 7.B) of the multifunctional profile and the suspension load-bearing lamella, the action of gravity, with the handle in (4.8) for the case of the supporting (4.A, 4.B) load-bearing lamellas, or in (5.8) in the case of suspended (5.A., 5.B) load-bearing lamellas, on the arm (4.9) of the supporting lamella, or on the arm (5.9) of the suspended load-bearing lamella, which arms represent the distances between the grips of gravity (4.8) and (5.8) and pivot axes (4.2) and (5.2), and in the direction (4.10) of the support and in the direction (5.10) of the suspension load-bearing lamella, causes the rotation of the roller joints of the support ( 4.1) as well as suspension (5.1) load-bearing slats around pivot axes (4.2) supporting (4.A., 4.B), i.e. pivot axes (5.2) suspension (5.A., 5.B), load-bearing lamellas, inside the capsule of the roller joints (3.1) of the assembly (6.A., 6.B) of the multifunctional profile and the supporting load-bearing lamella, that is, the assembly (7.A., 7.B) of the multifunctional profile and the suspension load-bearing lamella.

Thanks to this, in the initial position, when the assemblies, the multifunctional assembly (6.A., 6.B) with the supporting supporting lamella, as well as the multifunctional assembly (7.A., 7.B) with the suspension supporting lamella, are in a free state, the bearing surface (3.10) of the multifunctional (3.A., 3.B), longitudinal as well as transverse, profiles rests on the bearing surface (4.3) of the support, i.e. the bearing surface (5.3) of the suspension load-bearing lamella, which represents a completely closed, which is also and the initial position of the support (4.A., 4.B), as well as the suspension (5.A., 5.B), load-bearing lamella.

The maximum open position is limited by the contact of the top of the boundary (4.4) arm of the support arm, i.e. the top of the boundary arm (5.4) of the suspension lamella against the vertical wall of the side (3.3) longitudinal channel, whereby the shape and dimensions of the arm (4.9) support as well as the arm (5.9) suspension load-bearing slats ensures that the supporting (4.A., 4.B), as well as the suspension (5.A., 5.B), load-bearing lamellas, arm (4.9) support as well as arm (5.9) do not rotate in any position suspension slats must not be less than the specified amount.

The load-bearing grid of the clean room ceiling is made by stacking the appropriate number of assemblies (6.A., 6B) formed from multifunctional, longitudinal and transverse, load-bearing profiles of certain dimensions, with supporting load-bearing lamellas, in the case when the opening (8.11) in the grid of the load-bearing ceiling invests a filter unit for ventilation or assemblies (7.A., 7.B) of multifunctional, longitudinal and transverse, load-bearing profiles of certain dimensions, with suspended load-bearing lamellas in the case when a panel is inserted into the opening (8.11) in the grid of the load-bearing ceiling.

The formation of the ceiling grid is carried out in such a way that the assemblies (6.A., 6B; 7A., 7B) multifunctional, longitudinal and transverse, load-bearing profiles with the corresponding load-bearing lamellas are placed with each other, as a rule, at a right angle, in which way the appropriate the number of openings (8.11) in the grid of the load-bearing ceiling, which in terms of their number, dimensions and arrangement/location correspond to the requirements based on the type, dimensions and number of objects that are invested in the openings (8.11) in the grid of the load-bearing ceiling, for example panels or filter units for ventilation, whereby the longitudinal multi-functional load-bearing profiles in several adjacent assemblies (6A., 6B; 7A., 7B) can be united as a whole in one longitudinal multi-functional load-bearing profile.

The procedure for connecting assemblies (6.A., 6B) to each other formed by combining multifunctional, longitudinal and transverse profiles with associated supporting supporting lamellas or assemblies (7.A., 7.B) or by combining multifunctional, longitudinal and transverse profiles with associated suspension load-bearing lamellas, which is carried out in such a way that assemblies (6.A., 6B) or (7.A., 7.B) are placed with each other, as a rule, at a vertical angle, in such a way that between two longitudinal multifunctional profiles (6.A., 6.B) or (7.A., B) of the required length L (3.6) at a certain distance from each other in a vertical position, place the corresponding number of transverse (6.A, 6.B) or (7.A ., 7.B) profiles, and the longitudinal and transverse profiles (6.A., 6.B) or (7.A., 7.B) are connected to each other in such a way that the joint of the load-bearing longitudinal and transverse multifunctional profiles is performed as follows that holes (8.4) have been drilled through the multifunctional, longitudinal and transverse, profiles (6.A., 6.B) or (7.A., 7.B) in appropriate places, and longitudinal channels have been inserted into the connecting (3.3) h and transverse (6.A., 6.B) or (7.A., 7.B), profiles, connecting angles (8.1) are inserted through one surface of which round holes (8.5) are made and through the other surface elliptical penetrations (8.6 ).

The sizes and locations of the holes (8.4) on the longitudinal profiles (3A., 3B) are aligned with the sizes and locations of the round holes (8.5) on the corresponding corner surfaces (8.1), while the sizes and locations of the holes (8.4) on the transverse ones (3A., 3B) ) load-bearing profiles aligned with elliptical penetrations (8.6) in the other faces of the corners (8.1), in such a way that it is possible to insert the clamping screws (8.2) into the holes (8.4) in the longitudinal and transverse profiles (3A., 3B) and into the round holes ( 8.5) in one, that is, elliptical penetrations (8.6) in the other surface of the connecting angles (8.1), which makes it possible by tightening the nuts (8.3) of the clamping screws (8.2) to achieve a solid and reliable connection of multifunctional load-bearing longitudinal and transverse profiles (3A., 3. B).

Suspensions of the load-bearing ceiling raster consist of the upper (20.1) and the same number of lower (20.2) suspension parts of the load-bearing ceiling grid, whereby the upper (20.1) parts of the suspension are attached to the corresponding number of locations of the fixed supporting structure of the building, while the same number of lower (20.2) parts of the suspension connected to the grid of the load-bearing ceiling formed by assemblies (6.A., 6.B) or (7.A., 7.B), multifunctional longitudinal and transverse profiles in such a way as to slide the heads (20.3) in the form of a cube of the corresponding dimensions of the individual lower (20.2) suspensions are invested in the channels (3.2) for connection.

The process of connecting the upper (20.1) parts of the suspension, which were previously attached in the corresponding manner to the corresponding number of locations of the fixed supporting structure of the building, with the lower (20.2) parts of the suspension, whose sliding heads in the form of a cube (20.3) were previously inserted into the channels (3.2) ) for connection is carried out in such a way that the grid of the load-bearing ceiling, which is formed by assemblies (6.A., 6.B) or (7.A., 7.B), is placed on an appropriate number of suitable, for example, telescopic cranes, and the grid of the load-bearing assembly gradually rises upwards while simultaneously adjusting the locations of the block-shaped sliding heads (20.3) by moving them in the channels (3.2) so that the lower (20.2) parts of the suspension on which the threaded rods (22.2) are located are brought closer to the upper parts (20.1) on which are also threaded rods (22.2), so that their vertical axes practically coincide, when it becomes possible, by moving the upper (20.1) and lower (20.2) parts of the suspension in directions (22.4), to insert their threaded parts (22.2) into the upper, or bottom part Z – coupling (21.1), in which position the nuts (22.3) are tightened, which achieves the connection of the upper (20.1) and lower (20.2) parts of the suspension.

Adaptation of panels (12.2) or filter units (13.2) for ventilation for investment in openings (8.11) in the grid of the load-bearing ceiling is carried out so that, in the case of using suspended (5.A., 5.B) load-bearing slats, on the side panel panels (12.2) are made with appropriate grooves (12.1) designed to fit the supporting arms (5.5) of the suspended supporting lamellas (5.A., 5.B), while in the case of investing filter units for ventilation using support (4.A. , 4.B) of the load-bearing lamellas, on the lower surface (13.2) of the filter units for ventilation, derive suitable adjacent surfaces (13.1).

The grid of the load-bearing ceiling consists of assemblies (6.A., 6.B) or (7.A., 7.B) of multifunctional, longitudinal and transverse, load-bearing profiles with which the corresponding load-bearing slats are appropriately connected, in which way they are formed openings (8.11) in the load-bearing ceiling of the clean room, whereby the process of investing panels (12.2), i.e. filter units (13.2) for ventilation, into the openings (8.11) of the grid of the load-bearing ceiling of the clean room is carried out after the complete grid of the load-bearing ceiling has been suspended by the appropriate procedure to the solid structure of the building.

The process of investing panels (12.2), i.e. filter units (13.2) for ventilation, into the openings (8.11) of the grid of the load-bearing ceiling is carried out in such a way that the panel (12.2) or the filter ( 13.2) unit, and the platforms and the crane with the panel (12.2) or the filter unit (13.2) are located under the corresponding opening (8.11) of the load-bearing ceiling grid of the clean room, and the panel (12.2) or the filter unit (13.2) is gradually lifted up by means of the crane in the direction (14.3), whereby the surface of the object, panel or filter unit for ventilation, during this movement, engages the associated parts, (4.5) supporting parts (4.A., 4.B), or (14., 15., 16. ) or (5.5) suspension slats (5.A., 5.B), or (17., 18., 19), thereby causing rotational displacements of the load-bearing slats for a certain angle around the pivot axes (4.2) or (5.2), so that the load-bearing slats move from the initial support (14) or suspension (17) positions through intermediate positions of the supporting (15) or suspension (18) until the height and position is reached where the load-bearing lamellas, under the action of gravity, take the position in which the load-bearing arms (5.5) of the suspension lamellas jump into the grooves (12.1) on the side surfaces of the panels, or the position in which the supporting arms (4.5) of the supporting lamellas are under the adjacent surfaces (13.1) on the lower surface of the ventilation filter unit, when the associated object, panel or filter unit is slightly lowered to achieve complete insertion of the supporting arms (5.5) of the suspension lamellas in grooves (12.1), i.e. the complete abutment of the adjacent surfaces (13.1) on the lower surface of the ventilation filter unit on the supporting arm (4.5) of the supporting slats, which completes the process of inserting the panel, i.e. the ventilation filter unit into the associated opening (8.11) of the grid of the supporting ceiling clean rooms.
