The sealing ring includes a base, on which are provided a socket ring suitable for fitting onto the outer surface of the socket end, a plain ring suitable for fitting onto the outer surface of the plain end, and a closed connecting portion connecting the socket ring and the plain ring. Background Technology

[0002] Devices suitable for sealing and connecting tubular components are known in the prior art. For example, U.S. Patent 6,394,505 discloses such a device, which discloses a connection structure suitable for connecting a toilet outlet to a drain pipe. French Patent FR1503921 discloses a device for connecting a small-diameter drain pipe to a large-diameter drain riser.

[0003] In addition, a rapid construction technology called "Modular Integrated Construction" (MiC or "modular integrated construction") is known (see example website: https: / / mic.cic.hk / en / AboutMiC). This technology involves prefabricating building modules outside the construction site and then assembling these modules on the construction site to form a complete building. Summary of the Invention

[0004] The objective of this invention is to achieve a sealed connection between the socket end and the flat end in an economical and efficient manner. This connection method is particularly suitable for the discharge of sewage or rainwater in buildings, and its application advantages are even more prominent in buildings using modular construction technology.

[0005] Based on this, the present invention proposes a sealing ring as described above, wherein: the sealing ring has a static configuration in which the flat ring and the socket ring extend coaxially; the sealing ring also has an offset configuration in which the flat ring is radially offset relative to the socket ring; the connecting portion extends toward the inside of the socket ring; and the connecting portion is axially aligned with the socket ring.

[0006] Depending on the specific implementation of the sealing collar, it may include one or more of the following features:

[0007] The sealing collar allows for a limit offset angle between the flat-mouth ring and the socket ring, which is a maximum of 3° or 1°45′.

[0008] The sealing collar defines a socket direction, and the flat ring is offset relative to the socket ring along the socket direction;

[0009] In its static configuration, the connecting part has a shape that tapers from the socket ring to the flat ring, especially an approximate frustum shape;

[0010] The sealing collar includes one or more of the following features:

[0011] Socket fasteners suitable for securing a socket ring to the outer surface of the socket end; and

[0012] Flat-end fasteners suitable for holding or securing flat-end rings to the outer surface of the flat-end end.

[0013] The sealing collar includes a front lip that is adapted to fit against the end face of the flat end.

[0014] The present invention also relates to a tubular connection assembly, the assembly comprising: a first tubular member having a socket end, a second tubular member having a flat end, and a sealing ring for sealingly connecting the socket end and the flat end; wherein the socket end has an outer surface, the flat end has an outer surface, and wherein: the sealing ring is the sealing ring defined above, the socket ring being adapted to be fitted in a sealing manner onto the outer surface of the socket end; and the flat ring being adapted to be fitted in a sealing manner onto the outer surface of the flat end.

[0015] According to a specific embodiment of the tubular connection assembly, the assembly may include one or more of the following features: the socket end is provided with an external stop; in particular, the tubular connection assembly includes a retaining ring adapted to fix the socket end and the plain end relative to the wall of the building.

[0016] This invention also relates to a modular integrated building component, comprising: a first building module having a first building module structure, and a second building module having a second building module structure. The modular integrated building component includes the tubular connection components defined above, with a first tubular member fixed to the first building module structure and a second tubular member fixed to the second building module structure.

[0017] According to a specific implementation of the building component, it may include one or more of the following features: the first building module and the second building module are stacked vertically, and in particular, the second building module is disposed on top of the first building module.

[0018] The present invention also relates to a method for manufacturing a tubular joint, comprising the following sequential steps:

[0019] Provide the tubular connection assembly defined above;

[0020] Insert the socket ring onto the socket end;

[0021] Secure the sealing ring to the socket end; and

[0022] Insert the flat end into the flat ring. Attached Figure Description

[0023] The invention can be better understood by reading the following description taken in conjunction with the accompanying drawings, which are merely illustrative, wherein:

[0024] - Figure 1 This is a vertical cross-sectional schematic diagram of a portion of a modular integrated building component according to the present invention, which includes the tubular joint described in the present invention;

[0025] - Figure 2 for Figure 1 Partial sectional perspective view of the tubular joint;

[0026] - Figure 3 To be with Figure 1 Similar views illustrate a variation of the modular integrated building component partial structure according to the invention; and

[0027] - Figure 4 This is a partial sectional perspective view of a modified tubular joint according to the present invention. Detailed Implementation

[0028] Figure 1 A portion of a modular integrated building component according to the present invention is schematically shown, the component being generally designated as 2. This modular integrated building component 2 can be used to construct buildings such as residential or office buildings. The modular integrated building component 2 includes a first building module 4 and a second building module 6.

[0029] Before the modular integrated building component 2 is constructed, each building module 4 or 6 can be moved and operated independently of any other building module. Furthermore, each building module is already equipped with various facility components (such as pipes) and decorative components (such as tiles) before the modular integrated building component 2 is formed. Therefore, each building module 4 or 6 is considered a sub-component before the modular integrated building component 2 is formed.

[0030] The first building module 4 has a first building module structure 8, while the second building module 6 has a second building module structure 10.

[0031] Each building module structure includes, for example, at least one ceiling or floor, and one or more walls. Figure 1 The ceiling 12 of the first building module structure 8 and the floor 14 of the second building module structure 10 are shown as examples.

[0032] Figure 1 The illustration demonstrates a typical vertical arrangement of the modular integrated building component 2. In the example shown, the first building module 4 serves as the lower building module, while the second building module 6 serves as the upper building module. Therefore, the first building module 4 and the second building module 6 are arranged in a stacked configuration, specifically, the second building module 6 is positioned above the first building module 4.

[0033] The first building module 4 includes a first tubular member 20, which is fixed to the first building module structure 8, for example. Similarly, the second building module 6 includes a second tubular member 22, which is fixed to the second building module structure 10, for example. Preferably, before building modules 4 and 6 are assembled, the first tubular member 20 is fixed to the first building module structure 8, and the second tubular member 22 is also fixed to the second building module structure 10.

[0034] The first tubular member 20 is a pipe, specifically a lower pipe; the second tubular member 22 is also a pipe, specifically an upper pipe. In variations not shown, the first tubular member 20 and / or the second tubular member 22 may be an assembly consisting of one or more tubular connectors. The first tubular member 20 and the second tubular member 22 preferably have the same nominal diameter DN, for example, ranging from 10 mm to 300 mm. However, the nominal diameter DN of the first tubular member 20 may also be up to 50 mm larger than the nominal diameter DN of the second tubular member 22. The first tubular member 20 and / or the second tubular member 22 may be made of, for example, metal, especially cast iron. The first tubular member 20 and the second tubular member 22 may be used as components of, for example, sewage discharge pipes or rainwater discharge pipes.

[0035] The first tubular member 20 has a socket end 24. The socket end 24 has an outer surface 26, an inner surface 28, and an end face 30. The socket end 24 extends about its own central axis XX.

[0036] The second tubular member 22 has a flat end 32. The flat end 32 has an outer surface 34, an inner surface 36, and an end face 40. The flat end 32 extends about its own central axis YY.

[0037] exist Figure 1 In the arrangement shown, the central axis YY extends coaxially with the central axis XX. However, due to manufacturing and assembly tolerances, the central axis YY may be radially offset relative to the central axis XX, with a maximum offset distance of DM (e.g., the maximum offset distance DM is 20 mm or 10 mm).

[0038] For an example of this offset arrangement method, please see [link / details]. Figure 3 .exist Figure 3 In the process of assembling the second building module 6 with the first building module 4, there is an offset (specifically, a horizontal offset), which is related to... Figure 1 The two methods of alignment and assembly differ significantly. Therefore, in Figure 3 In the variant shown, the first tubular member 20 and the second tubular member 22 are also offset from each other.

[0039] Furthermore, due to manufacturing and assembly tolerances, the center axis YY may deviate angularly from the center axis XX (not shown in the figure), and there exists a maximum deviation angle. This maximum deviation angle varies with the nominal pipe diameter. For example, when the nominal pipe diameter is less than or equal to 200 mm, the maximum deviation angle is 3°; while when the nominal pipe diameter is greater than 200 mm, the maximum deviation angle is 1°45′.

[0040] The first tubular member 20 is installed on the first building module structure 8, while the second tubular member 22 is installed on the second building module structure 10. The installation positions of both must ensure that the flat end 32 can be smoothly inserted into the socket end 24 during the assembly of the second building module 6 and the first building module 4.

[0041] Modular integrated building component 2 includes a set of tubular connecting components 42. For example... Figures 1 to 3 As shown, in its assembled state, the tubular connection assembly 42 forms a tubular joint (or is itself a tubular joint). The tubular connection assembly 42 includes a first tubular member 20, a second tubular member 22, and a sealing collar 44. The sealing collar 44 is used to achieve a sealed connection between the socket end 24 and the flat end 32.

[0042] During the assembly of the modular integrated building component 2 (and the tubular joint), even if the radial offset between the socket end 24 and the flat end 32 reaches the maximum offset distance DM, the sealing collar 44 can still ensure the sealed connection between the socket end 24 and the flat end 32; at the same time, even if the angular offset between the socket end 24 and the flat end 32 reaches the maximum offset angle, the sealing collar 44 can also maintain the sealed connection between the socket end 24 and the flat end 32.

[0043] This sealing performance refers to waterproof sealing under an overpressure of at least 0.3 bar or at least 0.5 bar; or waterproof sealing under an overpressure of at least 1 bar. Preferably, especially in the latter case, socket fasteners 60 or flat-end fasteners 62 (see below) can be used to enhance pressure resistance.

[0044] The sealing collar 44 is a sealing collar used for pipe connections. The sealing collar 44 includes a base 46. For example, the base 46 is made of an elastic material with a Shore A hardness between 40 and 80, specifically between 50 and 70, such as an elastomer material. The base 46 is preferably made of ethylene propylene diene monomer (EPDM) rubber.

[0045] The base 46 includes: a socket ring 48 suitable for fitting onto the outer surface 26 of the socket end 24, a flat ring 50 suitable for fitting onto the outer surface 34 of the flat end 32, and a closed connection portion 52 for sealingly connecting the socket ring 48 and the flat ring 50.

[0046] The 48mm socket ring defines the center axis AA, and the 50mm flat socket ring defines the center axis BB. In the non-installed state, the center axis AA extends coaxially with the center axis XX, and the center axis BB extends coaxially with the center axis YY.

[0047] The sealing collar 44 has a static configuration in which the flat-mouth ring 50 and the socket ring 48 extend coaxially. This static configuration is... Figure 1 The configuration shown is a static configuration, meaning the sealing ring 44 is in the state when it is not subjected to an external force that causes the flat-mouth ring 50 to shift relative to the socket ring 48, typically corresponding to the uninstalled state of the sealing ring. The sealing ring 44 also has an offset configuration, in which the flat-mouth ring 50 is radially offset relative to the socket ring 48.

[0048] The connecting portion 52 extends inward toward the inside of the socket ring 48. Furthermore, the connecting portion 52 is axially aligned with the socket ring 48.

[0049] In its static configuration, the connecting portion 52 has a shape that tapers from the socket ring 48 to the flat ring 50. Specifically, it is approximately frustum-shaped.

[0050] The sealing collar 44 allows for an angular offset between the central axis BB of the plain ring 50 and the central axis AA of the socket ring 48. This offset angle can reach a maximum limit that still maintains a seal between the pipe components. This limit offset angle is consistent with the maximum offset angle mentioned above; specifically, depending on the nominal diameter of the pipe, the maximum limit offset angle can be 3° or 1°45′. Figure 1 In the diagram, the extreme offset angle is exaggeratedly illustrated by the angle α between axis (B)-(B) and axis AA.

[0051] The sealing ring 44 defines a socket direction SE. Specifically, the socket direction SE refers to the direction in which the plain end 32 is inserted into the socket end 24, and extends along the central axis AA and / or BB. The plain ring 50 is offset relative to the socket ring 48 along the socket direction SE, that is, axially offset along the central axis.

[0052] In other words, the sealing ring 44 includes a socket receiving end defined by the socket ring 48 and a flat receiving end defined by the flat ring 50. The insertion direction SE is the direction from the socket receiving end to the flat receiving end.

[0053] When the sealing ring 44 is in the installed state, the base 46 extends into the socket end 24, forming an internal cavity 56 between the base 46 and the socket end 24. The internal cavity 56 opens toward the first tubular member 20 so that when overpressure occurs within the first tubular member 20, the flat-mouth ring 50 is pressed against the flat-mouth end under the action of overpressure. In this case, the internal cavity 56 is defined by the flat-mouth ring 50 and the connecting portion 52.

[0054] The sealing collar 44 also includes a front lip 58, which is adapted to fit against the end face 40 of the flat end. The front lip 58 is a flange structure that projects radially inward from the flat ring 50. In the installed state, the end face 40 of the flat end fits tightly against the front lip 58. The front lip 58 can fit against the socket end 24, in which case the front lip 58 helps to achieve an effective seal between the flat end and the socket end. In addition, the front lip 58 also has an acoustic cushioning function, which is suitable for reducing or preventing vibration or noise caused by contact between the first tubular member 20 and the second tubular member 22. At the same time, the front lip 58 also serves to protect the socket end 24 and the flat end 32, avoiding wear or breakage that may occur due to direct contact between the socket end 24 and the flat end 32.

[0055] The sealing collar 44 is preferably equipped with a socket fastener 60, which is used to secure the socket ring 48 to the outer surface of the socket end 24. In this configuration, the socket fastener 60 is a metal retaining ring designed to ensure that the base 46 and the socket end 24 maintain tight contact in the socket assembly state.

[0056] The sealing collar 44 is preferably equipped with a flat-end fastener 62, which is suitable for retaining or securing the flat-end ring 50 to the outer surface of the flat end. In this configuration, the flat-end fastener 62 is a metal retaining ring designed to ensure that the base 46 and the flat end 32 maintain tight contact in the socket assembly state.

[0057] A socket ring 48 is adapted to be fitted in a sealing manner onto the outer surface of the socket end 24. For this purpose, the socket ring 48 preferably includes at least one inner sealing lip. A flat ring 50 is adapted to be fitted in a sealing manner onto the outer surface of the flat end. For this purpose, the flat ring 50 preferably includes at least one inner sealing lip. In both cases, the sealing performance is at least a drip-proof seal and / or capable of withstanding an overpressure of at least 0.3 bar.

[0058] The socket end 24 includes a socket section 70 and a bottom section 72. The socket section 70 is generally cylindrical, and the bottom section 72 tapers along the socket direction SE and is generally conical. The front lip 58 is adapted to fit onto the bottom section 72.

[0059] The socket end 24 preferably has an external stop 74, which is in the form of an external flange. This external stop 74 is used to limit the displacement of the first tubular member 20 relative to the first building module structure 8 (e.g., relative to the ceiling). In this case, the external stop 74 is located on the side of the first building module structure 8 facing away from the second building module 6. Alternatively, the external stop 74 may be integrated into the first building module structure 8 or the ceiling 12. Furthermore, the external stop 74 may also be located on the side of the first building module structure 8 facing the second building module 6.

[0060] The tubular connection assembly 42 may also optionally include a retaining ring 80 (see...) Figure 4 The retaining ring is suitable for fixing the socket end 24 and the flat end 32 relative to the wall of a building. For example, the retaining ring 80 is located on the side of the first building module structure 8 facing the second building module 6, and the external stop 74 is also located on this side and clamped between the retaining ring 80 and the ceiling 12. Alternatively, the retaining ring 80 and the external stop 74 are located on the side of the first building module structure 8 away from the second building module 6, and the external stop is clamped between the retaining ring 80 and the ceiling 12.

[0061] The assembly method of modular integrated building component 2 is as follows:

[0062] First, a first building module 4 and a second building module 6 are provided. In this state, a first tubular member 20 is fixed to the first building module structure 8, and a second tubular member 22 is fixed to the second building module structure 10.

[0063] At this point, the flat end 32 has not yet been inserted into the socket end 24.

[0064] If necessary, the flat-mouth fastener 62 can be installed on the flat-mouth ring 50.

[0065] The sealing ring 44 is fixed to the socket end by inserting the socket ring 48 onto the socket end. If necessary, the socket fastener 60 can be installed on the socket ring 48 to secure the socket ring 48 to the socket end.

[0066] At this time, the sealing ring 44 is in its stationary configuration.

[0067] Subsequently, the second building module 6 is placed on the first building module 4 along the socket direction SE. In this placement step, the flat end 32 is inserted into the socket end 24 along the socket direction SE. Before insertion, the flat end 32 may be radially offset relative to the socket end 24. In this case, when the flat end 32 is inserted into the socket end 24, the flat ring 50 will radially offset relative to the socket ring until the flat ring is radially aligned with the flat end 32, and thus coaxial with the flat end. The same applies if the flat end 32 has an angular offset relative to the socket end 24. After the flat ring 50 is aligned with the flat end 32, the flat end 32 is inserted into the flat ring 50.

[0068] In either case, the flat-end fastener 62 will hold or secure the flat-end ring 50 to the flat-end 32. The flat-end fastener 62 can be pre-tightened or tightened after installation.

[0069] In general, the method for manufacturing the tubular joint according to the present invention includes the following sequential steps:

[0070] Provide tubular connection assembly 42;

[0071] Insert the 48 socket rings onto the socket end 24;

[0072] Fix the sealing collar 44 to the socket end 24; and

[0073] Insert the flat end 32 into the flat ring 50;

[0074] This results in a tubular connector.

[0075] As a variation, the tubular connection component 42 (or tubular joint) may not be part of the modular integrated building component 2, but may be used in other technical scenarios. For example, the tubular connection component 42 or tubular joint may be part of the rainwater or sewage drainage pipes of a non-modular building. In this case, the building structure is first constructed, and then the tubular connection component 42 is fixed to the building structure to form the tubular joint.

[0076] The foregoing description includes the technical features of the present invention. Even if these technical features are presented in a specific technical context and may be combined with other technical features, they can be used independently of other technical features as long as they are technically feasible.
