Description

[0001] PIPELINE SYSTEM

[0002] The invention relates to a piping system, in particular a piping system for air conditioning technology, for a building manufactured by automated construction, which has been manufactured at least partially from building modules.

[0003] Automated construction, also known as modular construction, is a building method in which parts of a structure are assembled from prefabricated components called building modules. These modules are not manufactured on-site but simply assembled there. Automated construction results in shorter construction times and more cost-effective mass production of the building components.

[0004] One example of automated construction is modular large-panel construction, where the building is assembled modularly from prefabricated wall and ceiling panels. Another example is modular room construction, where prefabricated three-dimensional units, such as container-like building modules, are assembled to form a building. These methods can be combined.

[0005] After the building modules are assembled, the piping systems for the air conditioning of the buildings constructed in this way are installed conventionally, for example, by individually laying and installing air conditioning fluid lines within the building. An alternative manufacturing method for the piping systems involves integrating sections of pipe into the building modules before assembly. During assembly, not only the building modules but also the integrated pipe sections are connected. This is complex and requires great care, as precise alignment of the building modules to be assembled is necessary so that their pipe sections are also perfectly aligned with each other. US Patent 2,037,895 A shows a self-supporting room structure that can be transported as a unit.The room structure is equipped with facilities such as sanitary or lighting installations, connections for such installations that extend to the outside of the room structure and are accessible there for connection to suitable distribution systems of a building, and removable means to protect such connections during the transport of the room structure.

[0006] WO 2008 / 143496A concerns a room unit defined by a floor, a ceiling, two opposing longitudinal side walls, and two opposing end walls. These components are assembled into a modular unit. The first end wall is a facade wall section with a window. The second end wall contains an interior door. The room unit also includes a service shaft extending through it. One or more local networks are connected to this service shaft.

[0007] US Patent 3,677,285 A discloses a unit for conveying air and water in an induction system of an air conditioning system in a multi-story building, comprising a modular arrangement of water pipes and an air duct that are stationary within a housing and thermally insulated from each other and from the walls of the housing. Protruding end sections at opposite ends of the pipes and the duct are equipped with couplings for connecting adjacent end sections of the water pipes and air ducts of neighboring units. A support on each unit or module is designed to hold each unit in position on a floor where the connection between the pipes and air ducts of adjacent units is made. German Patent DE 10 2017 125 829 T2 relates to a method for manufacturing wall components for buildings, wherein cross-laminated timber panels of a specific width and length are stored in a magazine.The panels are sawn across their length to obtain cross-laminated timber (CLT) panels of the same width but shorter length, with several panels being placed across the direction of travel on a conveyor belt in such a way that the panels are flush at the top and bottom and the side edges of successive panels touch each other, with the panels being joined along the adjacent long sides on the conveyor belt to form a CLT carpet, and with the carpet being sawn across the direction of travel of the conveyor belt to obtain CLT panels of a defined width.

[0008] DE 690 08 856 T2 discloses a pipe routing structure for installation between the floors of a high-rise building, which accommodates sections of heating pipes, gas and water pipes, air conditioning pipes and similar riser pipes that run from floor to floor. The structure comprises a frame, at least one support plate connected to the frame and provided with openings for the riser pipes, and riser pipes guided through said openings and supported by said plate.

[0009] US Patent 11,214,945 B2 discloses a pipe shaft module comprising a pipe junction box and at least one pipe extending into the pipe junction box and provided on the pipe junction box in such a way that it can slide along its longitudinal direction with respect to the pipe junction box.

[0010] The problem addressed by the invention is to provide a piping system with air conditioning fluid lines that can be easily assembled for automated construction. This problem is solved by a piping system with the features of claim 1.

[0011] The piping system includes an installation shaft that extends over several floors through stacked building modules, with each building module containing a shaft section, and the stacked shaft sections forming the installation shaft. A piping module comprises air conditioning fluid lines that run parallel to each other, at least in sections, within the module. The piping module is designed to be inserted into the installation shaft, so that when the piping module is inserted, its air conditioning fluid lines are inserted together. The piping module includes a floor connection with first line connections for at least some of the air conditioning fluid lines, and an end connection with second line connections for the air conditioning fluid lines, located at one end of the piping module.The duct module is inserted into the installation shaft, and the floor connection is accessible through a lateral access opening in the installation shaft for the installation of an air conditioning unit at the floor connection.

[0012] The piping system results in simpler installation and routing of the air conditioning fluid lines.

[0013] The vertically stacked and assembled building modules, together with their shaft sections, form the service shaft. The service shaft is an open-topped cavity extending over several floors and building modules, housing the air conditioning fluid lines. The service shaft runs vertically as a riser shaft. Each building module has at least one shaft section designed as a continuous cavity. In the lowest building module, to which the service shaft leads, the shaft section may be a blind hole. Multiple shaft sections can be provided in each stacked building module to form several service shafts.

[0014] Air conditioning fluid lines serve as transport routes for fluids, i.e., gases and / or liquids, used in air conditioning systems (for example, heating, cooling, ventilation, humidification and dehumidification, fresh air supply, or at least one of these functions). These transport routes primarily run between a central air conditioning unit on the roof and air conditioning units on the building's floors. The air conditioning fluid lines can be designed as essentially rigid pipes or flexible hoses. The air conditioning units can be connected directly to the ductwork or via short connecting pieces, or they can be installed via floor ducts leading from the ductwork to the air conditioning units. The air conditioning units affect the indoor air quality, for example, by heating, cooling, filtering, humidifying, dehumidifying, and supplying fresh air, or only some of these functions.

[0015] For example, the central air conditioning unit can be designed as a temperature control unit, in which a temperature control medium, whose temperature is influenced by the central unit, flows from the central unit to the air conditioning units on the floors and back to heat or cool the rooms in the building. Additional air conditioning fluid lines can be provided for other functions mentioned.

[0016] Several air conditioning fluid lines are bundled together in the duct module. The air conditioning fluid lines run parallel to each other, at least in sections, and along the length of the duct module. In its installed state, this is also the length of the installation shaft. Advantageously, the air conditioning fluid lines run through the entire duct module between the end sections. However, a portion may also run only along a section of the duct module. In a simple embodiment, the air conditioning fluid lines bundled together in the duct module are held together in a single cable bundle. In another embodiment, the air conditioning fluid lines run within a cable duct, forming a rigid casing that protects the air conditioning fluid lines and defines a sheathing surface between the end sections. Thermal insulation can be provided between the casing and the air conditioning fluid lines.The cross-sectional contour of the cable module can be adapted to the installation shaft cross-section, so that the cable module can be installed with at least an almost positive fit. The cross-sectional contour can, for example, be rectangular.

[0017] The duct module allows the air conditioning fluid lines to be placed together and simultaneously when the module is inserted into the installation shaft. Their arrangement within the duct module remains unchanged. After the building modules are installed, the duct module is pushed lengthwise into the installation shaft. Advantageously, it extends over exactly one or more floors.

[0018] The duct module includes a floor connection that comprises the first connections of at least some of the air conditioning fluid lines. A first connection can be a branch of an air conditioning fluid line running through the duct module. Alternatively, the connection can be the end of an air conditioning fluid line leading to the floor connection. The latter is the case, for example, if the air conditioning fluid line only runs along a section of the duct module or if the floor connection is located in the lowest duct module. A connection can be designed, for example, as a plug connector or a twist-fit connector. The floor connection is accessible via an access opening in the installation shaft, allowing an air conditioning unit to be connected. The access opening is located laterally in the installation shaft. It can be a hole on the front or back of a wall section of the building module.Alternatively, it can be designed as a shaft or slot running within a wall section of the building module for air conditioning units recessed into the wall. The floor connection is aligned with the access opening and perpendicular to the longitudinal direction running between the opposing end sections.

[0019] In addition to the floor connection, an end connection of the duct module with secondary duct connections is also provided, which can be connected to the air conditioning unit or another duct module. Connection to a duct module, as used below, also refers to a fluidic connection, allowing fluids to flow into or out of the air conditioning fluid lines. The end connection is located at an end point, specifically at its end face. The end connection and its secondary duct connections are oriented at an angle, specifically at right angles, to the floor connection and the primary duct connections.

[0020] The installation shaft has an opening at the top through which the cable module can be inserted. The cable module is inserted into the installation shaft with its end section facing away from the end connection and the second cable connections.

[0021] The piping module simplifies the installation of air conditioning fluid lines and reduces the required time, as the fluid lines are inserted into the installation shaft only after the building modules have been assembled. The piping module industrializes the installation of air conditioning systems, particularly heating systems, in prefabricated houses and automated building construction. The prefabricated piping module comprises the air conditioning fluid lines, advantageously including their pipe insulation, and the vertical and horizontal connection devices for further piping modules or the connection elements of the air conditioning units. The piping module is inserted from the roof level through an installation shaft into the shaft sections integrated into the prefabricated building modules, thus forming a fluid supply path for the air conditioning system.The air conditioning units are connected to the air conditioning fluid lines, eliminating the need to install pipes in the floor and / or ceiling, thus reducing construction time and effort.

[0022] Advantageously, especially in multi-story buildings, several cable modules are provided in the installation shaft, which are inserted sequentially. They can be connected before all the cable modules are inserted, or by first inserting one cable module largely into the installation shaft, then connecting it to another cable module yet to be inserted, and then pushing the two connected cable modules further into the installation shaft together. In other words, a first cable module is connected to a second cable module that is already at least partially inserted before being pushed in, and then the connected cable modules are pushed further into the installation shaft together. This procedure can be repeated with additional cable modules, so that further cable modules are connected and then inserted step by step.Insertion can be assisted by a rope attached to the lowest duct module, which can be used to pull the connected duct modules into the installation shaft and / or guide them during insertion. The opposing shaft end sections of two adjacent shaft sections can have connecting elements that link the shaft sections. Alternatively, the adjacent shaft sections of two installed building modules are simply aligned with each other, and no connection beyond fixing the building modules is provided. For conventional building modules that already have integrated duct sections, precise alignment of the building modules and their integrated ducts is essential for installation.However, if the conduit modules are inserted only after the building modules have been assembled, as described above, an offset of building modules and shaft sections can also be tolerated, provided that the conduit module can still be inserted along the offset.

[0023] In one version, retaining elements are provided in the installation shaft and on the cable module, which interact in such a way that the cable module is held in its position in the installation shaft. This fixes the inserted cable module in the installation shaft, for example by screws or hooks that engage in eyelets.

[0024] In one version, the conduit module extends along all shaft sections, so that the entire building height is bridged by one conduit module.

[0025] With at least two cable modules inserted into the installation duct, the first and second cable modules each have a first and a second end connection at opposite end points. The first end connection of the second cable module is connected to the second end connection of the first cable module, so that their air conditioning fluid lines are fluidically connected. The second end connection comprises third line connections of the air conditioning fluid lines, which are fluidically connected to the second line connections of the second cable module. Further cable modules can be connected in the same way, so that the first end connection of one of the cable modules is connected to the second end connection of the adjacent cable module.

[0026] Advantageously, a connecting element is provided for the mechanical connection of the end sections of adjacent cable modules. For example, this could be a clamp or screw connection for the flanged end sections.

[0027] If the installation shaft extends along several building modules, access openings are provided in the various building modules. The lengths of the pipe modules can correspond to the height of the building modules, so that exactly one pipe module is provided in each shaft section.

[0028] If the duct module extends over more than one floor, it is advantageous to provide more than one floor connection so that air conditioning units can be connected on each floor.

[0029] Advantageously, the air conditioning fluid lines are prestressed. The prestressing is applied in tension, so that a tensile stress acts on one or more air conditioning fluid lines. In one configuration, the building modules are enclosed within a building section. If only one line module is provided in the installation shaft, its air conditioning fluid lines are prestressed at their ends and connected to the building section. If several line modules are provided, the air conditioning fluid lines of several line modules are connected to form a single line. The single line is connected to the building section at its ends, thus being prestressed. If there are multiple single lines, they are also fixed in place with prestress. Since the building itself has a significantly lower coefficient of thermal expansion than the air conditioning fluid lines, the effect of a temperature increase on the building section can be disregarded.

[0030] The connection to the building section can be made via fasteners that connect the end sections to the building section. For this purpose, the end sections advantageously protrude from the pipe modules. Alternatively, the connection can also be made via the pipe module that is connected to the building section. In such a connection, the air conditioning fluid pipes are firmly fixed at their ends within the pipe module, thus preventing any relative movement of the fixed end section to the building section.

[0031] Pre-tensioning counteracts thermally induced expansion of air conditioning fluid lines, for example, when they carry hot water, by at least limiting this expansion. Without pre-tensioning, temperature-related expansion would create a pressure state that could lead to buckling instability. With pre-tensioned pipes used as air conditioning fluid lines, the tension decreases with increasing temperature, but a pressure state that could lead to buckling instability is avoided.

[0032] Pre-tensioning during assembly can be done mechanically, for example using steel cables or by mounting the heated pipe.

[0033] In one configuration, the duct modules can be designed such that the air conditioning fluid lines are pre-tensioned and mounted within them. In another configuration, a roof duct for connecting fluid lines runs along the roof of a building constructed from these building modules. The roof duct runs between the installation duct and an equipment area where the central air conditioning unit can be located. Within the roof duct, beneath a covering layer and, in particular, a thermal insulation layer, run the connecting fluid lines between the central air conditioning unit and the uppermost duct module in the installation shaft.

[0034] In one embodiment, a tray acting as a liquid barrier is provided for the central air conditioning unit. The tray is positioned on the roof and has a surrounding rim. The connecting fluid lines run through the roof duct, over the rim, and into the interior of the tray, where they are connected to the central air conditioning unit. The tray protects the central air conditioning unit from moisture from below, particularly rainwater or melted snow.

[0035] Advantageously, a protective roof is provided over the basin to protect against precipitation and at least cover the area where the connecting fluid lines extend over the edge. The protective roof can be mounted on the central unit or designed as a freestanding roof structure.

[0049] Fig. 15 shows a roof area of ​​yet another embodiment of a pipeline system.

[0050] In the figures, identical or functionally equivalent components are provided with the same reference symbols.

[0051] Fig. 1 shows, as an embodiment of a piping system, a side view of a building section, which exemplarily comprises three stacked building modules 1. The building modules 1 are prefabricated building elements that were vertically assembled on-site during automated construction. The building modules 1 form a wall section of the building. They can be designed as wall panels or as part of a three-dimensional room module.

[0052] Each building module 1 has a vertical shaft section 3, which are arranged one above the other and, when assembled, form an installation shaft 5. The shaft sections 3 are connected by means of connecting elements 7, which in this embodiment are flange-shaped, to fix their alignment relative to each other. A conduit module 9 is inserted into the installation shaft 5 and extends along all the arranged building modules 1. The conduit module 9 extends vertically from the roof 11 to the ground. In an alternative embodiment with a basement, the conduit module 9 can extend down into the basement.

[0053] A central air conditioning unit 13 for heating, cooling, humidifying, dehumidifying, and / or ventilating is provided on the roof 11 of the building. The central air conditioning unit 13 is designed to influence the supply air for the rooms in the building and its quality and temperature. The connection from the central air conditioning unit 13 to air conditioning units 49 (not shown in Fig. 1), which influence the room air in the rooms, is made via air conditioning fluid lines 27 (shown in Fig. 1).

[0054] (1 not shown), which run longitudinally bundled in the line module 9. On the roof side, the line module 1 is connected to the air conditioning central unit 13 via connecting fluid lines 85 (not shown in Fig. 1). The connecting fluid lines 85 are bundled in a connection module 15.

[0055] Fig. 2 shows a side view of a building section as a further embodiment of a piping system. To avoid repetition, only the differences from the previous embodiment are described.

[0056] In this embodiment, no connecting elements 7 are provided for the shaft sections 3. Several pipe modules 9 are arranged one above the other and interconnected. In this embodiment, one pipe module 9 is provided per shaft section 3. The pipe modules 9 are arranged one above the other in the installation shaft 5 and interconnected, so that air conditioning fluids can flow through the air conditioning fluid lines 27 (not shown in Fig. 2) of the pipe modules 9 in the installation shaft 5.

[0057] Holding means 17 are provided on the installation shaft 5 and on the cable modules 9, which interact in such a way that the cable modules 9 are held in their position in the installation shaft 5.

[0058] Fig. 3 shows, as a further embodiment of a piping system, a side view of a building section which, by way of example, has three building modules 1 mounted on top of each other. Each building module 1 has a vertical shaft section 3. These are arranged one above the other and form an installation shaft 5. Piping modules 9 are inserted into the installation shaft 5, in which air conditioning fluid lines 27 run. The piping modules 9 and the air conditioning fluid lines 27 are connected to each other at their facing end faces, so that a mechanical connection between the piping modules 9 and a mechanical and fluidic connection between the air conditioning fluid lines 27 are created. The air conditioning fluid lines 27 of several piping modules 9 are connected to form composite lines 95. The composite lines 95 run from the ground to the roof.The interconnected lines 95 are designed as interconnected pipes, each extending along a line module 9.

[0059] The ends of the interconnected pipes 95 are connected to the building so that they are prestressed. The connection is made at the lowest pipe module 9 by connecting the end sections of the air conditioning fluid lines 27 protruding from the lowest pipe module 9 to a foundation 98 of the building. The end sections of the air conditioning fluid lines 27 protruding from the uppermost pipe module 9 are fixed to the building by means of a fastening device 97. Alternatively, the fastening can also be indirect, by attaching the uppermost pipe module 9 to the building. In this case, the end sections of the air conditioning fluid lines 27 are fixed in the pipe module 9 in such a way that the fastening of the pipe module 9 to the building does not allow any relative movement between the end sections of the air conditioning fluid lines 27 and the building.

[0060] By fixing the end sections of the composite lines 95 during the assembly of the line modules 9, an initial prestress is created, resulting in a tensile stress acting on the composite lines 95. This prestress has the effect of limiting or preventing temperature-related expansion of the air conditioning fluid lines 27, which are designed as tubes. The initial prestress decreases with increasing temperature. Nevertheless, the prestress prevents a pressure condition from developing in the composite line 95, which could lead to kinking instability. Even if significant heating were to cause a pressure condition, the pressure on the composite line 95 would be lower than without prestress.In comparison with pipes, whose temperature-related expansion can be in the range of centimeters, for example in the case of stainless steel pipes, the building can be considered as an almost temperature-independent rigid body, since it is subject to significantly lower thermal fluctuations and has a coefficient of thermal expansion that is orders of magnitude lower than that of the pipe steel.

[0061] The described assembly with pre-tensioning can also be used if only one cable module 9 is inserted into the installation shaft 5.

[0062] Fig. 4 illustrates how the pipe modules 9 are successively inserted into the installation shaft 5 and connected to one another. A pipe module 9 is inserted into the installation shaft 5 up to its upper, first end section 39 and then connected to a lower, second end section 40 of another pipe module 9, so that the air conditioning fluid lines 27 (not shown in Fig. 4) of the pipe modules 9 are fluidically connected. The connected pipe modules 9 are then partially inserted into the installation shaft, so that only an end section of the upper pipe module 9 protrudes. This state is shown in Fig. 4. The two already connected pipe modules 9 are then connected to the lower, second end section 40 of yet another pipe module 9. The connected pipe modules 9 are then further inserted into the installation shaft 5.These steps are repeated until interconnected cable modules 9 extend along the entire installation shaft 5.

[0063] In this embodiment, no connecting elements 7 are provided for the shaft sections 3. Even if the shaft sections 3 of the assembled building modules 1 should have a slight offset, this hardly hinders the insertion of the already connected cable modules 9, provided that the cross-section of the installation shaft 5 in the offset area still allows the insertion of the cable modules 9.

[0064] Fig. 5 shows a top view of an embodiment of a building module 1, which forms a wall section of a building. A continuous shaft section 3 with a rectangular cross-section runs through the building module 1. In this embodiment, the front and back surfaces 19, 21 of the building module 1 run parallel in the area of ​​the shaft section 3. In an alternative embodiment, the front surface 19 and / or the back surface 21 can be projecting to provide sufficient space for the shaft section 5 in the case of thin walls.

[0065] Fig. 6 shows a top view of an embodiment of a duct module 9. The duct module 9 has a rectangular cross-section with a laterally projecting floor connection 23 with first line connections 29 of the air conditioning fluid lines 27 for connecting an air conditioning unit 49 (not shown in Fig. 6). The cross-section is defined by a duct channel 25 in which the air conditioning fluid lines 27 of the duct module 9 run. In an alternative embodiment, the floor connection 23 is flush with the outer surface of the duct module 9 formed by the duct channel 25. Flanges projecting beyond the outer surface are provided at the end regions 39, 40 to allow two duct modules 9 to be connected to each other.

[0066] The cross-section of the conduit module 9 is shaped such that it can be inserted into the conduit shaft 5 (shown in Fig. 6). Advantageously, the cross-sections correspond in such a way that the conduit module 9 can be inserted in a predetermined orientation and / or can be inserted in a form-fitting manner relative to the horizontal.

[0067] The duct module 9 is equipped with four air conditioning fluid lines 27, which run side by side between the end sections 39 and 40 through the duct module 9. Liquids or gases, such as a temperature control medium or fresh and exhaust air, can be transported through the air conditioning fluid lines 27. Second and third line connections 31 and 33 of the air conditioning fluid lines 27 are provided at the ends of the end sections 39 and 40 to connect the duct module 9 to a central air conditioning unit 11 via connecting fluid lines 85 (not shown in Fig. 6) or to connect it to another duct module 9.

[0068] Fig. 7 shows a side view of two connected line modules 91, 92 from Fig. 6, through which air conditioning fluid lines 27 run along a longitudinal direction 35.

[0069] The first cable module 91 has a floor connection 23 with first cable connections 29 between the end sections 39 and 40. At the end sections 39 and 40, second cable connections 31 encompassed by the first end connection 37 and opposing third cable connections 33 encompassed by the second end connection 38 are provided. The second cable module 92 has two floor connections 23 arranged one above the other with first cable connections 31 between the end sections 39 and 40. At the end sections 39 and 40, second cable connections 31 and opposing third cable connections 33 are provided.

[0070] The connected line modules 91, 92 are aligned along the longitudinal direction 35. The second line connections 31 of the second line module 92 are fluidically connected to the third line connections 33 of the first line module 91. A mechanical connection is achieved by clamps as connecting means 81 on the superimposed flanges of the end regions 39, 40.

[0071] Fig. 8 shows, as an embodiment of a piping system, a side view of the interior of a building section comprising two floors 41. Two superimposed building modules 1 form the side walls of the floors 41, between which a ceiling 43 runs. An installation shaft 5 runs within the building modules 1, formed by the shaft sections 3 of the building modules 1 and also passing through the ceiling 43. A piping module 1 with air conditioning fluid lines 27 (not shown in Fig. 8) running longitudinally 35 is inserted into the installation shaft 5.

[0072] The access openings 47 are arranged in the installation channel 5 on the front faces 19 of the building modules 1. The floor connections 23 of the duct module 9 are accessible through the access openings 47. One of the floor connections 23 (bottom of Fig. 8) has only two first duct connections 29 for a portion of the air conditioning fluid lines 27. Another floor connection 23 (top of Fig. 8) has four first duct connections 29 for all air conditioning fluid lines 27 of the duct module 9.

[0073] In each floor 41 through which the conduit module 9 runs, a floor connection 23 is provided as an example. In another embodiment, more or fewer floor connections 23 may be provided in the floors 41. The number of floor connections 23 also need not be the same in each floor 41.

[0074] At each of the floor connections 23, an air conditioning unit 49 is mounted on the wall, which is fluidically connected to the first line connections 29.

[0075] The air conditioning units 49 can, for example, be temperature control units with fresh air supply, through which the rooms are tempered and supplied with additional fresh air.

[0076] Fig. 9 shows a further embodiment of a line module 9, which is connected at its upper side to another line module 9, shown only in part.
