The partition wall structure is a construction structure often used in buildings, and through the keel structure, a partition wall base or a shielding base of a specific space can be formed in the building space, so as to support the modeling and fix the structure.

[0003] At present, the keel framework structure is made by the traditional construction method of raw material entering the site and on-site cutting, and is usually fixed and installed on site by using one-time permanent fasteners such as screws, and is not easy to reset after installation. Limited by the manufacturing form of the existing keel framework structure, during the building construction, the manufacturing demand of assembly type factory pre-processing, pre-assembly and on-site positioning installation cannot be realized, the pre-assembly, calibration, positioning and other multiple disassembly and assembly cannot be realized during the installation process, and the customized effect of high requirement cannot be achieved. Therefore, how to design the framework system to meet the disassembly and assembly requirements in different situations and ensure the on-site construction effect is an important problem. CONTENT OF THE INVENTION

Each keel component comprises two mating surfaces arranged oppositely, each mating surface is provided with a first groove for sliding of a sliding piece, the plurality of keel components are spliced with each other to form a framework in a preset plane, and the direction of each mating surface is parallel to the preset plane. The plurality of connecting pieces are arranged corresponding to the end portions of the plurality of keel components, each connecting piece comprises a first connecting portion and a second connecting portion connected together, the first connecting portion and the second connecting portion abut on the mating surfaces of different keel components, and are fixed on the keel components by locking and fixing of the fasteners and the sliding pieces. The plurality of covering panels are laid and fixed on one side or both sides of the framework.

[0006] The embodiment of the present application provides an assembled prefabricated framework system, which forms a wall structure through cooperation of a framework and a covering panel. When the framework is formed by splicing of keel members, a detachable connection mode is applied. The fitting surface of each keel member is provided with a first groove for sliding of a sliding piece, so that a basis is provided for the connection effect of the connecting piece. The connecting part of the connecting piece can abut against the fitting surface of the keel member, and the plurality of keel members are fixed through the locking cooperation between the fastener and the sliding piece. Thus, a stable framework system is formed, and through application of the flexible and detachable connection mode at the fixed position, the prefabricated framework system can meet the requirements of pre-assembly, calibration, positioning and other multiple disassembly requirements in the process of prefabrication, assembly, positioning and installation of the prefabricated framework system in the factory, so that the on-site construction effect is ensured.

[0007] In some embodiments, the two fitting surfaces of each keel member are provided with a closing part protruding in a direction away from each other, and the closing part covers part of the surface of the connecting piece. In this way, the closing part provided on the fitting surface can facilitate positioning and limiting of the connecting piece when the connecting piece is fixed.

[0008] In some embodiments, the edge of the covering panel is attached to the closing part. In this way, the closing part can facilitate the fixed connection between the edge of the covering panel and the keel member.

[0009] In some embodiments, the plurality of keel members are spliced with each other along two mutually perpendicular directions to form the framework.

[0014] In some embodiments, each keel member is provided with a second groove on the surface parallel to the preset plane, and a sliding piece is arranged in the second groove.

The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific embodiments of the present application, and the embodiments can be combined and referred to each other without contradiction.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion.

[0032] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connecting", "connecting" and other terms should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] As shown in Figures 1 to 13 Some embodiments of the present application provide a prefabricated skeleton system, which includes a plurality of keel members 11, a plurality of connecting members 12 and a plurality of covering panels 13. Each keel member 11 includes two mating surfaces 101 arranged oppositely, each mating surface 101 is provided with a first groove 102 for sliding of a sliding member 14, a plurality of keel members 11 are spliced with each other in a preset plane to form a skeleton 10, and each mating surface 101 is oriented parallel to the preset plane. A plurality of connecting members 12 are arranged corresponding to the end portions of the plurality of keel members 11, each connecting member 12 includes a first connecting portion 121 and a second connecting portion 122 connected to each other, the first connecting portion 121 and the second connecting portion 122 abut on the mating surfaces 101 of different keel members 11 and are fixed on the keel members 11 by locking and fixing of fasteners 15 and the sliding members 14. A plurality of covering panels 13 are laid and fixed on one side or both sides of the skeleton 10.

[0034] The keel member 11 is the basis of forming the skeleton system, and the required skeleton 10 can be formed by splicing the keel members 11 with each other. A plurality of keel members 11 can be spliced in a form of longitudinal and transverse interlacing or with a certain inclination angle between each other. Each keel member 11 applies a detachable bolted connection form, that is, a groove is formed on the surface of each keel member 11 matched with each other, which provides convenience for forming a detachable connection form between different keel members 11. The sliding member 14 can be placed in the groove, and the sliding member 14 itself can slide along the groove to be connected with the keel member 11 through the groove. Thus, the connection and fixing position between the keel members 11 is adapted. The groove is provided through at both ends and in a reverse T shape, which has the characteristics of narrow opening and wide interior, so that the sliding member 14 cannot escape from the groove along the orientation direction of the mating surface 101 after entering the groove. The sliding member 14 has a threaded structure, such as a sliding block nut or a sliding block connected with a screw rod, which can form a base for connection and fixation of a bolt or a nut and the like. On any mating surface 101 of the keel member 11, the sliding member 14 can provide a mounting and fixing base at a specific position of the keel member 11.

[0035] The connection pieces 12 are used to connect and fix the joint positions between any two keel members 11. Each connection piece 12 includes a plurality of connection portions connected to each other, and different connection portions of each connection piece 12 can correspond to different mating surfaces 101 of the keel members 11. The connection portions have through holes 125 to facilitate the cooperation between the sliding pieces 14 and the fasteners 15. For example, when the connection portions abut against the keel members 11, the screws can be screwed through the through holes 125 and threadedly cooperated with the sliding nuts, so as to realize the connection and fixation between the connection pieces 12 and the keel members 11. Meanwhile, the joint positions of the two keel members 11 cooperating with the same connection piece 12 are bound, so that the two keel members 11 are connected to form a whole. By adopting the cooperation form of the detachable fasteners 15, the fasteners 15 can be removed when needed, so as to realize the separation between different keel members 11. The connection portions of the connection pieces 12 can be provided in the form of flat plates to ensure the abutment effect between the mating surfaces 101 of the keel members 11. The plurality of connection portions of the connection pieces 12 can be provided in the form of an integral structure to ensure the structural strength. The connection pieces 12 are located within the edges of the mating surfaces 101 of the keel members 11 and do not protrude on both sides of the mating surfaces 101 in the vertical direction of the preset plane, so as to facilitate the laying of the cover panels 13.

[0036] The cover panels 13 can be closed on one side or both sides of the framework 10 to form a covering structure, cover the framework 10 formed by the joint of the keel members 11, and form a complete wall structure. The cover panels 13 can also serve as the basis for subsequent decoration, for example, puttying or covering other decorative layers on the complete plane formed by the cover panels 13.

[0037] The assembly type prefabricated framework system provided by some embodiments of the present application forms a wall structure by cooperation of the framework 10 and the cover panels 13. When the framework 10 is formed by the joint of the keel members 11, a detachable connection form is applied. The mating surface 101 of each keel member 11 is provided with a first groove 102 for sliding of the sliding piece 14, which provides a basis for the connection effect of the connection piece 12. The connection portions of the connection piece 12 can abut against the mating surface 101 of the keel member 11 and fix the plurality of keel members 11 through the locking cooperation between the fastener 15 and the sliding piece 14. Thus, a stable framework system is formed. By applying the fixed-position flexible and detachable connection mode, the prefabricated framework system can meet the requirements of multiple disassembly and assembly such as pre-assembly, calibration and positioning during the process of prefabrication and assembly in the factory to the site positioning and installation, and the on-site construction effect is ensured.

[0038] It should be noted that the grooves on the surface of the keel member 11 not only facilitate the connection and fixation of different keel members 11, but also facilitate the assembly and expansion of the surface of the keel member 11. For example, various pipelines and different electromechanical module units can be installed in a certain form, and electrical and mechanical installation components such as wiring pipes, water supply pipes, drainage pipes, pre-buried valve groups, and pre-buried point positions are assembled on both sides of the preset plane of the framework 10 to realize the separation and prefabrication assembly of the electromechanical module pipeline. According to the specific application scene and use requirements, the electromechanical module unit can be subdivided into bathroom basin modules, toilet modules, shower modules, equipment room water treatment modules, inpatient physiological monitoring modules, etc. The prefabricated framework is used for electromechanical integration design in different building spaces.

[0039] In some embodiments, the two fitting surfaces 101 of each keel member 11 can be provided with a necking portion 103 protruding away from each other. The necking portion 103 covers part of the surface of the connecting piece 12.

[0040] The necking portion 103 is formed at the edge position of the fitting surface 101 and protrudes on the fitting surface 101 to form a flange structure on the fitting surface 101 of the keel member 11. The necking portion 103 can be provided on one side edge or opposite side edges of each fitting surface 101. The necking portion 103 can position and limit the connecting piece 12 to ensure that the connecting piece 12 is located within the edge of the fitting surface 101.

[0041] In addition, the edge of the covering panel 13 can be attached to the necking portion 103.

[0042] The necking portion 103 facilitates the connection and fixation of the covering panel 13. The fastener 15 for fixing the covering panel 13 can be arranged according to the position of the necking portion 103. The fastener 15 only needs to pass through the covering panel 13 and be connected to the necking portion 103 to achieve the fixing effect of the covering panel 13 on one side of the keel member 11. In this way, when laying the covering panel 13, the edge of the covering panel 13 can be arranged at a position between the two fitting surfaces 101 of the keel member 11, i.e., the edge of the covering panel 13 can correspond to the middle symmetry line position of the keel member 11 to ensure that the adjacent two covering panels 13 are tightly jointed. Moreover, the adverse effects of the fastener 15 on the main part of the keel member 11 can be reduced when fixing the covering panel 13.

[0043] In some embodiments, a plurality of keel members 11 can be spliced together along two mutually perpendicular directions to form a framework 10.

[0044] That is, the keel members 11 can be spliced together in a relatively regular form to form the framework 10. A part of the keel members 11 can be spliced together along the horizontal direction (X direction) and the vertical direction (Y direction) to form the framework 10. Figure 6The other part of the keel component 11 can be spliced ​​along the vertical direction (where the center line segment XX' is located). Figure 6 The keel components 11 are spliced ​​together in the direction of the center line segment YY', thus forming a relatively stable skeleton structure. The keel components 11 arranged in different directions can withstand loads in different directions, ensuring the overall structural strength of the skeleton 10. In practice, the keel components 11 can be made of high-strength materials, such as hard aluminum extrusion profiles, as the body material of the structural keel components. Aluminum alloy has good mechanical properties, high usability, and is easy to process with high precision. At the same time, the manufacturing precision of aluminum extrusion profiles is higher than that of thin-walled steel profiles and square steel profiles, providing a matching product for millimeter-level construction precision on site.

[0045] In addition, the keel components 11 arranged in different directions can have different lengths, and two or more shorter keel components 11 can be spliced ​​between two adjacent longer keel components 11.

[0046] The keel components 11 located in different positions can have different lengths to adapt to their respective splicing positions. For example... Figure 6 As shown, the longer keel members 11 can be arranged horizontally, and two or more shorter keel members 11 can be spliced ​​between two longer keel members 11. The longer keel members 11 form vertical load-bearing members, and the shorter keel members 11 can serve as connectors at different positions of the longer keel members 11. Figure 7 As shown, the longer keel members 11 can be arranged vertically, and two or more shorter keel members 11 can be spliced ​​between two longer keel members 11. The longer keel members 11 form horizontal load-bearing members, and the shorter keel members 11 can serve as connecting members at different positions of the longer keel members 11.

[0047] like Figure 8 As shown, the keel members 11 arranged in the same direction can have different lengths, and the length of the two keel members 11 that are furthest apart is greater than the length of the keel member 11 between them.

[0048] In other words, keel components 11 arranged along the same direction can also have different lengths. The two keel components 11 furthest apart in the same direction are usually spliced ​​with multiple keel components 11 in another direction; therefore, the two furthest keel components 11 can have a longer length. For example... Figure 8As shown, the two keel members 11 farthest apart in the vertical direction correspond to the top and bottom positions of the framework 10, and a plurality of keel members 11 arranged along the horizontal direction, i.e. longitudinal keel members, are spliced between the two. The keel members 11 at the middle position in the vertical direction are spliced between two adjacent longitudinal keel members, and shorter lengths can be used to connect the two adjacent longitudinal keel members. In actual cases, as shown in Figure 9 As shown, shorter transverse keel members can also not be provided between two adjacent longitudinal keel members, so as to reduce the number of components and simplify the structure of the framework system.

[0049] In some embodiments, as shown, each connecting piece 12 can further include a third connecting portion 123 connected to the first connecting portion 121, the third connecting portion 123 being arranged opposite to the second connecting portion 122, and the third connecting portion 123 and the second connecting portion 122 abutting on different mating surfaces 101 of the same keel member 11. Figure 10

[0050] That is, when the keel member 11 has recesses on both sides of the connecting surface, more than two connecting portions can be provided in the connecting piece 12. In this way, the connecting piece 12 has connecting portions corresponding to the different sides of the surface of the keel member 11, ensuring the fixing effect of the keel member 11.

[0051] In addition, each connecting piece 12 can be provided with a protruding portion 124 protruding from the surface of the first connecting portion 121, the protruding portion 124 being located between the second connecting portion 122 and the third connecting portion 123, and the surface of the keel member 11 parallel to the predetermined plane being provided with a second recess 104, and the protruding portion 124 being inserted into the second recess 104.

[0052] The protruding portion 124 is provided protruding from the surface of the first connecting portion 121 and located between the second connecting portion 122 and the third connecting portion 123. At the abutting position of the keel members 11 with the same cross-sectional shape, the protruding portion 124 can be inserted into the second recess 104 of the keel member 11, thereby playing a positioning effect and limiting the movement of the keel member 11.

[0053] The width of the protruding portion 124 is greater than the width of the opening of the second recess 104, which can limit the movement of the keel member 11 in the horizontal or vertical direction. At the same time, the protruding portion 124 has a bent portion, which can form a corresponding abutting relationship with the bent portion of the recess opening, thereby enhancing the positioning effect.

[0054] In some embodiments, each keel member 11 can be provided with a second recess 104 on the surface parallel to the predetermined plane, and a sliding member 14 is arranged in the second recess 104.

[0055] ​That is, the two surfaces of the keel member 11 arranged along the width direction can also be provided with grooves penetrating through both ends. In this way, when connecting the fittings on the keel member 11, the fittings can be fixed on the two surfaces of the keel member 11 parallel to the preset plane. This is conducive to the installation and fixation of the fittings, so as to expand the electromechanical equipment.

[0056] As shown in Figures 11 to 13 , the sliding member 14 can be arranged in the second groove 104 arranged along the width direction of the keel member 11. The sliding member 14 can be provided with a column structure facing the front-rear direction (the direction of the center line segment ZZ’). 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 connected with the column structure to fix the assembly position of the sliding member 14. The arrangement of the column structure can form a hanging base for the assembly expansion of the hanging fittings. Figure 11

[0057] As shown in Figure 1 and Figure 2 , the prefabricated framework system during assembly can also include a partition layer 16, which is filled in the enclosed space formed by different keel members 11, and the edge of the partition layer 16 abuts against the fitting surface 101 of different keel members 11.

[0058] In actual cases, the partition layer 16 can be made of sound insulation material or thermal insulation material to achieve sound insulation effect or thermal insulation effect.

[0059] Those skilled in the art can understand that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present application.​
