Description

Technical Field

[0001] The embodiments of the present application relate to the field of building construction technology, and in particular to a prefabricated frame, a preassembled module and a dry construction method. Background Art

[0002] With the development of residential technology and the improvement of quality of life, people have put forward higher standards and requirements for high-quality construction of concealed projects and customized delivery of use space in new and renovated projects. As a common structural component of concealed projects, keels bear multiple functions such as structural force, comprehensive embedding, and modeling support in spatial entity structures such as walls, ceilings, and floors. While providing the basic structure for the finished surface construction, it is closely related to the quality of the finished surface construction.

[0003] The existing keel structure is processed by the traditional construction method of raw materials entering the site and cutting on site. It is usually fixed and installed on site using one-time permanent fasteners such as screws. The installation precision is low and it is not easy to reset after disassembly. Limited by the traditional construction method, the existing keel cannot realize the construction method of pre-processing, pre-assembly and on-site positioning installation in the prefabricated factory with millimeter-level size control. In the field of construction, the assembly construction method of realizing high-precision multiple assembly, repeated disassembly and precise placement of keel structure is an important issue to improve the high-quality construction standards of concealed projects and meet the customized delivery requirements of the use space. Summary of the invention

[0004] The purpose of the implementation mode of the present application is to provide a prefabricated frame, preassembled modules and dry construction method, which can be conducive to prefabricated assembly that meets both standardized and customized construction needs and ensures the efficiency and quality of construction implementation and project delivery.

[0005] To solve the above technical problems, the embodiment of the present application provides a prefabricated skeleton. The prefabricated skeleton includes a plurality of first keel components arranged at intervals along a first direction on a preset plane, a plurality of second keel components arranged in sequence on the preset plane along a second direction, and a connector. Each first keel component has a first mating surface and a second mating surface arranged opposite to each other along the first direction, and the first mating surface and the second mating surface are respectively provided with a first groove extending along the second direction for sliding of the sliding member, and the second direction is perpendicular to the first direction. Each second keel component is provided with a second groove extending along the first direction for sliding of the sliding member, and each second keel component abuts against at least two first keel components. The connector is connected at the abutment between the first keel component and the second keel component, and the connector includes a first connecting portion and a second connecting portion connected to each other, one of the first connecting portion and the second connecting portion abuts against the first keel component, and is fixed to the first keel component by locking and matching the fastener with the sliding member in the first groove, and the other of the first connecting portion and the second connecting portion abuts against the second keel component, and is fixed to the second keel component by locking and matching the fastener with the sliding member in the second groove.

[0006] The embodiment of the present application also provides a preassembled module. The preassembled module includes the above-mentioned prefabricated frame, assembly parts and covering panels. The assembly parts are fixed to the first keel component of the prefabricated frame by locking and matching between the fastener and the sliding member in the first groove, or are fixed to the second keel component of the prefabricated frame by locking and matching between the fastener and the sliding member in the second groove. The assembly parts are used to fix wiring pipes, water pipes or electromechanical equipment. The covering panels are laid and fixed on one side or both sides of the prefabricated frame in the first direction.

[0007] The embodiment of the present application further provides a dry construction method, the dry construction method comprising:

[0008] Manufacturing a first keel component, a second keel component and a connecting piece;

[0009] The first keel member, the second keel member and the connecting member are assembled to form the above-mentioned prefabricated frame;

[0010] Fixing the assembly parts on the first keel member or the second keel member, and fixing the wiring pipe, water pipe or electromechanical equipment through the assembly parts;

[0011] The covering panels are laid on one side or both sides of the prefabricated frame in the first direction, and the covering panels are fixed to the first keel component and / or the second keel component by fasteners.

[0012] The prefabricated skeleton, preassembled module and dry construction method provided by the embodiments of the present application are provided with grooves on the surface of the keel components at different positions, which can provide space for the assembly and position adjustment of the sliding parts. After the keel components are abutted against each other to form a preliminary skeleton system, different keel components can be connected and fixed by the locking cooperation between the connecting parts and the fasteners and the sliding parts. Thereby forming a stable skeleton system. By applying a flexible and detachable connection method, the prefabricated skeleton system can be realized from factory prefabrication and assembly to on-site positioning and installation. Multiple disassembly and assembly requirements such as preassembly, calibration, and placement can be achieved to ensure the on-site construction effect.

[0013] In some embodiments, at least part of the second keel member has a cross-sectional area smaller than that of the first keel member, and at least part of the second keel member includes an installation surface and a non-installation surface that are arranged opposite to each other, and the installation surface is provided with a second groove. In this way, by using a keel member with a smaller cross-sectional area, the prefabricated skeleton structure can be simplified, and convenience can be provided for the expansion of electromechanical equipment.

[0014] In some embodiments, the distance between the mounting surface and the non-mounting surface is smaller than the width of the first mating surface or the second mating surface in a third direction, and the third direction is perpendicular to the preset plane. In this way, by setting a smaller distance between the mounting surface and the non-mounting surface, it is beneficial to achieve a gap in the skeleton system.

[0015] In some embodiments, the end of the second keel member abuts against two adjacent first keel members, the installation surface of the second keel member is parallel to the second direction, and the non-installation surface of the second keel member is close to one side of the first keel member along the first direction, and the installation surface of the second keel member and the other side of the first keel member along the first direction form a reserved space. In this way, by forming the reserved space, an accommodation area can be provided for the arrangement of the expansion component to ensure the compactness of the structure.

[0016] In some embodiments, the ends of each first keel member are respectively abutted against two second keel members that are farthest apart in the second direction, and the mounting surfaces of the two second keel members that are farthest apart in the second direction are perpendicular to the second direction. In this way, by using narrower keel members to replace edge keels, it is beneficial to embed the skeleton system in an existing frame.

[0017] In some embodiments, the projections of the first mating surface and the second mating surface on the installation surface are located within the edge of the installation surface. In this way, the laying effect of the covering board can be ensured by controlling the size of the mating surface.

[0018] In some embodiments, the second keel member has the same cross-sectional shape as the first keel member, and the connector further includes a third connection portion connected to the first connection portion, the third connection portion is arranged opposite to the second connection portion, and the second connection portion and the third connection portion abut against opposite surfaces of the second keel member. In this way, the stability of connecting and fixing different keel members can be enhanced by increasing the number of connection portions.

[0019] In some embodiments, the connector further includes a protrusion connected to the first connection portion, the protrusion is located between the second connection portion and the third connection portion, the second keel member is provided with a third groove, and the protrusion is inserted into the third groove. In this way, the keel member can be positioned by the protrusion and the easy movement of the keel member can be restricted.

[0020] In some embodiments, each first keel component is provided with a third groove on a surface parallel to the preset plane, and a sliding member is provided in the third groove. In this way, by providing grooves on the other two side surfaces of the keel component away from the mating surface, it is convenient to expand other components.

[0021] In some embodiments, at least one of the two second keel members abutting against the ends of the same plurality of first keel members has the same cross-sectional shape as the first keel member. In this way, the structural strength can be improved and the structural stability can be ensured by using keel members with the same cross-sectional shape.

[0022] In some embodiments, there are multiple first grooves and multiple second grooves, and the multiple first grooves are arranged in parallel with each other, and the multiple second grooves are arranged in parallel with each other. In this way, the fastening effect of the fastener can be improved by increasing the number of grooves. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in each embodiment of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not constitute any limitation, and the various embodiments can be combined with each other and referenced to each other without contradiction.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0061] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0062] Existing keel frame structures are mostly made of thin-walled steel or square steel, and are manufactured using the traditional construction method of on-site cutting of raw materials. Screws and other disposable permanent fasteners are usually used for on-site fixing and installation, which are difficult to reposition after disassembly after installation.

[0063] Limited by the manufacturing form of the keel skeleton structure, the existing keel cannot meet the construction requirements of pre-fabrication, pre-assembly and on-site positioning and installation in the prefabricated factory.

[0064] In order to realize the construction requirements of factory pre-processing and pre-assembly of structural keel skeleton systems such as building space walls and ceilings, as well as flexible assembly and free positioning on site, the present invention provides a dry construction product system and construction method based on prefabricated skeletons and pre-assembly. Among them, in order to change the rough operation of on-site processing of raw materials and one-time installation on site, the prefabricated skeleton system restructures the traditional thinking and construction paradigm of conventional operations in the engineering field from the product dimension. The prefabricated skeleton system includes keel components and universal mounting parts. The keel components can be aluminum alloy keel components, which are bolted to the universal mounting parts through threaded fasteners. The application of a detachable bolted connection method can realize the multiple disassembly and assembly requirements of the prefabricated skeleton system from factory prefabrication and assembly to on-site positioning and installation, such as pre-assembly, calibration, and placement. The prefabricated skeleton system and customized pre-processing and pre-assembly module units provide a complete landing solution for prefabricated dry construction, opening up the transformation path from factory to site and from product to project, while improving the construction quality and efficiency of concealed projects. The prefabricated dry construction installation and building method used in concealed projects in dry and wet areas can provide an adaptive installation base for different finishing surface process requirements, achieving seamless construction quality of the finished surface and high-end design of the interior space.

[0065] Combine the following Figures 1 to 28 The structure of the prefabricated skeleton provided in some embodiments of the present application is described.

[0066] like Figures 1 to 6 As shown, the prefabricated skeleton 10 provided in some embodiments of the present application includes a prefabricated skeleton 10 provided in a first direction ( Figure 1 A plurality of first keel components 11 are arranged at intervals along the second direction ( Figure 1A plurality of second keel components 12 and a connecting member 13 are sequentially arranged on a preset plane (in the direction where the midline segment YY' is located). Each first keel component 11 has a first mating surface 101 and a second mating surface 102 arranged opposite to each other along a first direction. The first mating surface 101 and the second mating surface 102 are respectively provided with a first groove 111 extending along a second direction for sliding the sliding member 14. The second direction is perpendicular to the first direction. Each second keel component 12 is provided with a second groove 121 extending along the first direction for sliding the sliding member 14. Each second keel component 12 abuts against at least two first keel components 11. The connecting member 13 is connected at the junction of the first keel component 11 and the second keel component 12. The connecting member 13 includes a first connecting portion 131 and a second connecting portion 132 that are connected to each other. One of the first connecting portion 131 and the second connecting portion 132 abuts on the first keel component 11 and is fixed to the first keel component 11 through the locking cooperation between the fastener 15 and the sliding member 14 in the first groove 111. The other of the first connecting portion 131 and the second connecting portion 132 abuts on the second keel component 12 and is fixed to the second keel component 12 through the locking cooperation between the fastener 15 and the sliding member 14 in the second groove 121.

[0067] The prefabricated frame 10 is formed by combining keel components arranged in different directions, and is the basis for supporting the shape and fixing the structure in the building structure. The preset plane can be a wall designed in the building space that needs to be partitioned, a ceiling that needs to be suspended, a ground that needs to be laid, or other planes.

[0068] A plurality of first keel components 11 are arranged at intervals along a first direction to form a splicing foundation. The first direction can be a horizontal direction or a vertical direction. In other words, the first keel components 11 can be arranged along a horizontal direction or a vertical direction. Figure 1 As shown, when the first keel member 11 is arranged along the horizontal direction, it corresponds to the vertical force bearing member. Figure 2 As shown, when the first keel components 11 are arranged along the vertical direction, they correspond to the horizontal force-bearing components. According to the actual arrangement requirements, the number of the first keel components 11 can be two or more than three.

[0069] The first keel component 11 is provided with mating surfaces on both opposite sides, and the mating surfaces are provided with grooves extending in the length direction. The grooves are provided through both ends, and are in an inverted T-shape, with the characteristics of being narrow at the opening and wide inside, and can be loaded with a sliding member 14, which is confined in the groove. The sliding member 14 has a threaded structure, such as a slider nut or a slider provided with a screw, which can form a base for fasteners 15 such as bolts or nuts to connect and fix. On any mating surface of the first keel component 11, the sliding member 14 can provide an installation and fixing foundation at a specific position of the first keel component 11.

[0070] The plurality of second keel members 12 are arranged in a direction different from the first keel member 11 and abut against the first keel member 11, so as to form a design basis for different finished surfaces. The second keel member 12 is also provided with a groove for the sliding member 14 to slide, and the sliding member 14 can provide an installation and fixing basis at a specific position of the second keel member 12.

[0071] The second keel member 12 is fixed to the first keel member 11 by a connector 13. The connector 13 has different connecting parts, each of which can be fixed to different positions of the keel member. The connecting part has a through hole 135 so as to cooperate between the fastener 15 and the sliding member 14. For example, when the connecting part abuts against the keel member, the screw can be threadedly matched with the slider nut through the through hole 135 to achieve the connection and fixation between the connector 13 and the keel member. By adopting a detachable threaded matching form, the keel member can be disassembled by removing the fastener 15 when necessary. The connecting part can be set to a flat plate shape to ensure the abutment effect with the keel member. Different connecting parts of the connector 13 can adopt an integrally formed structure to ensure the overall structural strength. The connector 13 is located in the space formed by the keel member and does not protrude from both sides of the prefabricated skeleton 10 in the vertical direction of the preset plane to ensure the compactness of the overall structure.

[0072] The prefabricated skeleton 10 provided in some embodiments of the present application has grooves on the surface of the keel components at different positions, which can provide space for the assembly and position adjustment of the sliding member 14. After the keel components are abutted against each other to form a preliminary skeleton system, different keel components can be connected and fixed by the locking cooperation between the connecting member 13 and the fastener 15 and the sliding member 14. Thereby forming a stable skeleton system. By applying a flexible and detachable connection method in a fixed position, the prefabricated skeleton system can be realized from factory prefabrication and assembly to on-site positioning and installation. Multiple disassembly and assembly requirements such as pre-assembly, calibration, and placement can be achieved to ensure the on-site construction effect.

[0073] It should be noted that the grooves on the surface of the keel components not only facilitate the connection and fixation of different keel components, but also facilitate the assembly and expansion of the surface of the keel components. For example, various pipelines and different electromechanical module units can be installed in a certain form, and electromechanical installation components such as strong and weak current wiring pipes, water supply pipes, drainage pipes, embedded valve groups, and embedded points can be assembled on both sides of the preset plane where the prefabricated skeleton 10 is located to realize the prefabrication and assembly of electromechanical module pipeline separation. According to the specific application scenario and usage requirements, the electromechanical module unit can be subdivided into bathroom basin modules, toilet modules, shower modules, equipment room water treatment modules, inpatient room physiological monitoring modules, etc. The prefabricated skeleton 10 can be used to carry out mechatronic design in different building spaces.

[0074] In addition, since the existing keel skeleton is limited by the structural stress form, the structural strength of a single keel is relatively weak, and it is usually necessary to combine with the cladding plate material to form a load-bearing component with the surface as a whole. It is impossible to pre-assemble the assembly unit independently, and it is also impossible to achieve customized flexible assembly and free positioning in both vertical and horizontal directions. Therefore, in terms of material selection, the prefabricated skeleton system of the present invention can use higher-strength materials, such as hard aluminum extruded profiles as the main material of the structural keel components. Aluminum alloy materials have good mechanical properties, strong workability, and are easy to process with high precision. At the same time, the manufacturing precision of aluminum extruded profiles themselves is higher than that of thin-walled steel profiles and square steel profiles. The aluminum alloy structural keel components provide a matching execution product for millimeter-level construction precision on site.

[0075] In actual situations, the first keel member 11 and the second keel member 12 can use keel members with the same structure or keel members with different structures, so as to assemble the required skeleton system in different occasions. That is, in some embodiments, a part of the keel member with a larger cross-sectional area can be used as the main keel member to bear the main force. Another part of the keel member with a smaller cross-sectional area is used as a secondary keel member as the basis for extended assembly. In other words, the prefabricated skeleton system can be assembled by combining the main keel member, the secondary keel member, and the connector 13, and can be expanded in both the assembly height and the assembly width. The main keel member can be used as a vertical force-bearing member or a horizontal force-bearing member, and is applied to structural structures in different areas such as walls and ceilings. It is also suitable for wall structures with different installation characteristics such as openings, niches, and hanging cabinets, as well as integrated performance practices, pipeline separation, point layout and other comprehensive embedded installation requirements. The local use of secondary keel components in the structural system composed of main keel components can derive more types of assembly units. For example, using secondary keel components to replace cross braces can create a through structural cavity, and using secondary keel components to replace the top and bottom keels can place the pre-assembled skeleton system as a whole into the existing frame.

[0076] like Figures 7 to 10 As shown, at least part of the second keel component 12 may have a smaller cross-sectional area than the first keel component 11 , and at least part of the second keel component 12 includes an installation surface 122 and a non-installation surface 123 that are oppositely disposed, and the installation surface 122 is provided with a second groove 121 .

[0077] Part or all of the second keel member 12 may be a structure with a smaller cross-sectional area than the first keel member 11. The second keel member 12 of this part is provided with a second groove 121 on one side surface thereof, that is, a base for connection, fixation and assembly and expansion is formed on one side surface thereof. The other side surface may be oriented toward the side away from the first keel member 11, that is, toward the four sides or two sides of the prefabricated frame 10. Fig.11 and Fig.12 As shown, the second keel component 12 can be connected and fixed at the edge of the first keel component 11 in a side-by-side posture, thereby forming a connection and fixing foundation on one side of the installation surface 122. The connecting member 13 adopts Fig.13 The angle bracket connector shown in the figure may be provided with a smaller contact area at the portion contacting with the mounting surface 122. Fig.14 and Fig.15 As shown, the second keel member 12 can also be connected and fixed to the first keel member 11 in a flat position to ensure the load sharing effect in the width direction. Fig.13 The angle code connector shown in the figure can be connected and fixed by simply changing the placement of the connector 13.

[0078] By utilizing the smaller cross-sectional area of ​​at least part of the second keel member 12, a favorable space can be formed in the prefabricated frame 10 for assembly and expansion of other components, which is conducive to reserving the required space for assembly and expansion of other components, thereby ensuring space utilization efficiency and overall aesthetics.

[0079] In some embodiments, the distance between the mounting surface 122 and the non-mounting surface 123 may be smaller than the distance between the first mating surface 101 or the second mating surface 102 in the third direction ( Figure 1 The width in the direction of the midline segment ZZ', and the third direction is perpendicular to the preset plane.

[0080] The distance between the mounting surface 122 and the non-mounting surface 123 is Figure 8 The thickness of the second keel member 12 is shown in FIG. That is, the thickness of at least part of the second keel member 12 is less than the width of the first keel member 11. That is, when the non-installation surface 123 is close to one side edge of the first mating surface 101 or the second mating surface 102, a certain distance is formed between the installation surface 122 and the other side edge of the first mating surface 101 or the second mating surface 102.

[0081] like Figure 8 As shown, the second keel member 12 with a smaller cross-sectional area located in the middle position is placed sideways and abuts against two adjacent first keel members 11. The two surfaces with larger areas formed by the mounting surface 122 and the non-mounting surface 123 are perpendicular to the width direction of the first keel member 11. In addition, the non-mounting surface 123 is close to the edge of the first keel member 11. Thus, an assembly space is formed on one side of the mounting surface 122.

[0082] That is, the end of the second keel component 12 with a smaller cross-sectional area abuts against two adjacent first keel components 11, the installation surface 122 of the second keel component 12 is parallel to the second direction, and the non-installation surface 123 of the second keel component 12 is close to one side of the first keel component 11 along the first direction, and the installation surface 122 of the second keel component 12 and the other side of the first keel component 11 along the first direction form a reserved space.

[0083] In actual situations, the pre-assembled skeleton system that uses secondary keel components to replace cross braces provides a complete fixed skeleton for the factory prefabrication of electromechanical modules. The electromechanical module unit uses the universal countersunk sockets provided by the main keel components and the secondary keel components as the electromechanical pipeline assembly expansion dock, and integrates and assembles the electromechanical installation components such as the strong and weak current wiring pipes, water supply pipes, drainage pipes, embedded valve groups, embedded points, etc. involved in the electromechanical module in the structural cavity, thereby realizing the separate prefabrication and assembly of the electromechanical module pipelines.

[0084] Furthermore, the width of the secondary keel member as a cross brace can be smaller than that of the primary keel member, so that the two surfaces of the secondary keel member arranged in the width direction are located within the area within the closing surface of the first keel member 11. It is ensured that the surface of the secondary keel member as a cross brace does not protrude outside the primary keel member. At the same time, the two surfaces of the secondary keel member as a cross brace arranged in the width direction can be abutted against the closing of the first keel member 11 to ensure the stability of the connection between the two.

[0085] In addition, the mounting surface 122 of the second keel component 12 may also be perpendicular to the second direction. Figure 7 and Figure 8 As shown, the second keel member 12 with a smaller cross-sectional area at the edge position is laid flat and abuts against two adjacent first keel members 11. The two surfaces with larger areas formed by the mounting surface 122 and the non-mounting surface 123 are perpendicular to the extension direction of the first keel member 11, that is, the length direction.

[0086] In some embodiments, the ends of each first keel component 11 respectively abut against two second keel components 12 that are farthest apart in the second direction, and the mounting surfaces 122 of the two second keel components 12 that are farthest apart in the second direction are perpendicular to the second direction.

[0087] like Figure 7 and Figure 8As shown, the two ends of the three first keel components 11 are respectively abutted against the two second keel components 12 that are farthest apart in the second direction. In addition, the installation surfaces 122 of the two second keel components 12 that are farthest apart in the second direction face the direction of approaching each other, and the non-installation surfaces 123 face the direction of moving away from each other. That is, the secondary keel components are used as the top keel and the ground keel. By using the secondary keel components to replace the top and bottom keels, the prefabricated frame can be placed in the existing frame as a whole, so as to cooperate with the prefabricated frame and the existing frame.

[0088] The middle part can use the main keel member or the secondary keel member. Figure 8 In the case shown in FIG. 1 , the second keel member 12 located in the middle position uses a secondary keel member as a cross brace, which can not only reduce the load of the first keel member 11, but also facilitate the assembly and expansion of subsequent electromechanical equipment. Fig. 9 As shown, the middle part may not be provided with a keel component as a cross brace, so as to reduce the number of components used, simplify the structure of the prefabricated frame 10, and reduce the manufacturing cost of the prefabricated frame 10.

[0089] In actual situations, the projections of the first mating surface 101 and the second mating surface 102 on the mounting surface 122 may be located within the edge of the mounting surface 122 .

[0090] That is, the first keel member 11 supported between the two second keel members 12 that are farthest apart in the second direction is within the space defined by the two opposite mounting surfaces 122. In this way, the flatness of the prefabricated frame 10 on both sides of the preset plane can be ensured, and no protruding parts are formed inside the prefabricated frame 10. Thus, the flatness of the covering board 31 when it is laid can be ensured.

[0091] In some embodiments, the second keel member 12 may have the same cross-sectional shape as the first keel member 11. Fig.18 As shown, the connecting member 13 further includes a third connecting portion 133 connected to the first connecting portion 131 . The third connecting portion 133 is arranged opposite to the second connecting portion 132 . The second connecting portion 132 and the third connecting portion 133 abut against opposite surfaces of the second keel component 12 .

[0092] That is to say, Figures 16 to 18 As shown, when connecting keel components with grooves on both sides, more than two connecting parts can be provided in the connecting member 13. So that the surfaces on different sides of the connecting member 13 corresponding to the keel components are connected and fixed by connecting parts, thereby ensuring the fixing effect of the keel components.

[0093] Similarly, at the end of the first keel component 11, the following Fig.18The connecting member 13 shown is connected and fixed. The connecting parts arranged opposite to each other in the connecting member 13 can abut against the surfaces of different sides of the keel component, and the connection and fixation are achieved through the fastener 15.

[0094] In addition, the connecting member 13 may further include a protrusion 134 connected to the first connecting portion 131 , the protrusion 134 is located between the second connecting portion 132 and the third connecting portion 133 , the second keel component 12 is provided with a third groove 112 , and the protrusion 134 is inserted into the third groove 112 .

[0095] The protrusion 134 is formed by protruding from the surface of the first connection part 131 and is located between the second connection part 132 and the third connection part 133. At the abutment of the keel components with the same cross-sectional shape, the protrusion 134 can be inserted into the third groove 133 of the keel component, thereby achieving a positioning effect and limiting the movement of the keel component.

[0096] like Fig.17 As shown, the width of the protrusion 134 is greater than the width of the opening of the third groove 112, which can limit the movement of the keel component in the third direction. At the same time, the protrusion 134 has a bent portion, which can form a corresponding abutment relationship with the bent portion at the opening of the groove, thereby enhancing the positioning effect.

[0097] In some embodiments, each first keel member 11 is provided with a third groove 112 on a surface parallel to the preset plane.

[0098] That is, grooves with two ends passing through can also be provided on the two surfaces of the keel member arranged along the width direction. In this way, when the assembly part 16 is connected to the main keel member, it can be fixed on the two surfaces of the main keel member parallel to the preset plane. This is conducive to the installation and fixation of the assembly part 16 for the expansion of electromechanical equipment.

[0099] like Figures 19 to 21 As shown, a sliding member 14 may be arranged in the third groove 112 of the keel member in the width direction. The sliding member 14 may be provided with a column structure, the column structure is provided with an external thread, and the fastener 15 is in the form of a nut. The fastener 15 is threadedly matched with the column structure to fix the assembly position of the sliding member 14. The column structure can form a suspension foundation for the assembly and expansion of the hanging parts.

[0100] In some embodiments, at least one of the two second keel members 12 abutting against the ends of the same plurality of first keel members 11 has the same cross-sectional shape as the first keel member 11 .

[0101] like Fig. 22 and Fig.23As shown, the two second keel members 12 that are farthest apart in the second direction are simultaneously in contact with the ends of the three first keel members 11. And the two second keel members 12 have the same cross-sectional shape as the first keel members 11. That is, in actual situations, the main keel member can be used as a top keel or a ground keel, or as a horizontal force-bearing member. By using the main keel member to bear the main force, the structural strength of the entire skeleton system can be ensured. Fig. 22 The difference of the prefabricated frame 10 shown is that Fig.23 The prefabricated frame 10 shown uses secondary keel components instead of cross braces, which can form a through space in the space surrounded by the keel components to assemble and arrange pipelines, electromechanical equipment and other components. Fig.24 As shown, the middle part may not be provided with a keel component as a cross brace, so as to reduce the number of components used, simplify the structure of the prefabricated frame 10, and reduce the manufacturing cost of the prefabricated frame 10.

[0102] In some embodiments, there may be a plurality of first grooves 111 and a plurality of second grooves 121 , and the plurality of first grooves 111 are disposed parallel to each other, and the plurality of second grooves 121 are disposed parallel to each other.

[0103] like Figure 3 and Figure 4 As shown, two first grooves 111 and two second grooves 121 are provided, and the two first grooves 111 and the two second grooves 121 are arranged along the direction of two parallel lines. By increasing the number of the first grooves 111 and the second grooves 121, the connection and fixing effect of the connecting member 13 on the keel component can be ensured, and the stability when different keel components are connected and fixed can be ensured.

[0104] The keel system provided in some embodiments of the present application can achieve millimeter-level factory pre-processing, pre-assembly, and on-site positioning and installation. And realize the independent, freely positioned, and flexible assembly of customized prefabricated assembly module unit structures. The single-layer keel structure formed by the combination of keel components optimizes the internal cavity space size of the prefabricated skeleton system, and the overall structure is more compact, which improves the efficiency of space utilization. At the same time, the assembled dry construction installation and construction method are applied to concealed projects in dry and wet areas to simultaneously improve the construction quality and construction efficiency. The assembled dry construction installation and construction method can meet the process requirements of different finished surfaces, seamless effects and high-end design of interior spaces.

[0105] Some embodiments of the present application also provide a preassembled module, which includes the above-mentioned prefabricated frame 10, assembly parts 16 and covering panels 31. The assembly parts 16 are fixed to the first keel component 11 of the prefabricated frame 10 through the locking cooperation between the fastener 15 and the sliding part 14 in the first groove 111, or fixed to the second keel component 12 of the prefabricated frame 10 through the locking cooperation between the fastener 15 and the sliding part 14 in the second groove 121. The assembly parts 16 are used to fix the wiring tube 17, water pipes or electromechanical equipment. The covering panels 31 are laid and fixed on one side or both sides of the prefabricated frame 10 in the first direction.

[0106] The prefabricated frame 10 provides convenience for the assembly and arrangement of other components in the building space. On the first keel component 11 or the second keel component 12, the assembly parts 16 can be used as an expansion basis to fix other components. Figures 23 to 31 The specific forms of the assembly parts 16 and pre-assembled modules of different structural forms are illustrated. Fig.25 and Fig.26 As shown, the wiring tube 17 can be fixed by the pipeline kit to arrange the strong and weak current cables. Figures 27 to 30 As shown, the water supply pipe 18 or the drainage pipe 19 can also be fixed by a pipeline set to arrange the water pipes. Figure 31 to Figure 33 The structures of basin module, shower module and toilet module assembled by using prefabricated frame 10 are shown respectively. Fig.31 As shown, different water supply pipes 18 can be fixed on one side of the prefabricated frame 10 to supply hot water and cold water respectively, and drain them down through the fixed drainage pipe 19. Fig.32 As shown, a water supply pipe 18 can be fixed on one side of the prefabricated frame 10 to supply water for showering, and a valve assembly 20 can be fixed by installing a flat plate-like assembly 16 to achieve control of the water for showering. The assembly 16 can be fixed in a vertical position in a suitable space of the prefabricated frame 10. Fig.33 As shown, a water supply pipe 18 can be fixed on one side of the prefabricated frame 10 to provide water to the toilet tank 21, and the toilet tank 21 can be fixed and installed by a flat assembly 16. The assembly 16 can be fixed at a suitable position of the prefabricated frame 10 in a flat posture. When the pipeline passes through the keel component at the top or bottom position, a perforation can be opened on the keel component to facilitate the passage of the pipeline.

[0107] like Fig.34 and Fig.35 As shown, the covering panels 31 can be fixed on both sides of the prefabricated frame 10, and the space surrounded by the keel components can be filled with a partition 32 to form a complete wall structure. The partition 32 can be made of sound insulation material or heat insulation material to achieve sound insulation effect or heat insulation effect. Fig.34The difference between the prefabricated frame 10 shown in FIG. 1 and the cladding panels 31 is that Fig.35 The prefabricated frame 10 shown in the figure and located between the covering panels 31 reduces the use of cross bracing members, which can simplify the structure of the prefabricated frame 10 and reduce the manufacturing cost of the prefabricated frame 10.

[0108] In actual situations, the prefabricated skeleton system and pre-assembled assembly units can be assembled on site based on the gypsum board installation module, and arranged and connected and pre-buried and filled according to the planned pipeline integration and performance structure, and finally the concealed engineering cladding layout, screw positioning and installation operations are completed using dry construction methods. The structural shape of the assembly part 16 can be designed according to the actual assembled parts, including but not limited to plate, rod, tube or other irregular shapes.

The keel members can have the same cross-sectional shape or different cross-sectional shapes. The connector 13 can be selected according to the cross-sectional shape of the keel member to be connected to match the connection and fixing requirements of different keel members.

[0112] Step S120 , assembling the first keel component 11 , the second keel component 12 and the connecting member 13 to form the above-mentioned prefabricated frame 10 .

[0117] After the components on the prefabricated frame 10 are arranged, the covering panels 31 may be used to cover one or both sides of the prefabricated frame 10 to complete the covering layout of the concealed project.

[0118] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
