Description

Technical Field

[0001] This utility model relates to the field of keel frame technology, specifically to an assembled keel frame. Background Technology

[0002] Prefabricated keel frames are core structural components in prefabricated buildings, used to construct lightweight partition walls, ceiling systems, and pipeline supports. They are typically assembled from metal profiles using standardized connectors. Traditional keel frames still rely on welding for some connections, which suffers from low construction efficiency and difficulty in adjustment and modification. Right-angle connections in traditional keel frames use snap-fit ​​connectors with bent inserts, a complex manufacturing process that increases production costs. Furthermore, traditional snap-fit ​​connectors lack compressive strength measures, making them unsuitable for the load-bearing requirements of large-span ceilings or partition walls. Pipeline installation requires additional welded supports, compromising the structural strength of the keel frame itself.

[0003] Therefore, it is necessary to design a prefabricated keel frame that is highly practical, quick to assemble, and structurally stable. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 The present invention provides a technical solution: an assembled keel frame, comprising two sets of keel frames arranged symmetrically, the keel frames having a square structure, each of the three adjacent sides of the keel frame being provided with a single lightweight keel 1, and the fourth side of the keel frame being composed of two parallel lightweight keels 1.

[0027] A triangular buckle assembly is provided at the right-angle intersection of adjacent lightweight keel 1, a flat buckle assembly is provided in the middle of lightweight keel 1, a flat buckle base 5 is provided in the middle of the two flat buckle assemblies, the flat buckle base 5 is used to connect the two sets of keel frames, an L-shaped extension block 6 is provided on one side of one flat buckle assembly, a pipe clamp assembly is provided on one side of one flat buckle assembly, and a scale 11 is provided on one side of lightweight keel 1.

[0028] The frame consists of two symmetrically distributed lightweight keel units, each unit adopting a square structure enclosed on four sides. Three adjacent sides are each fitted with a single lightweight keel 1 with a rectangular cross-section, while the fourth side uses two parallel lightweight keels 1 of the same specification, forming a reinforced load-bearing side. This improves bending resistance and adapts to the installation requirements of heavy pipelines or equipment. Triangular snap-fit ​​components are installed at the right-angle intersections of adjacent lightweight keels 1. One corner of the triangular snap-fit ​​component is a right angle, used for connection and fixation at right angles.

[0029] Each lightweight keel 1 can have a flat snap-fit ​​assembly installed in its middle. The flat snap-fit ​​assembly is first installed in the middle of two symmetrical lightweight keels 1, and then a flat snap-fit ​​base 5 is installed between the two flat snap-fit ​​assemblies. This connects the two symmetrical frames. After the triangular snap-fit ​​assembly and the flat snap-fit ​​assembly are installed on the keel, they can be fixed with bolts for overall stability. One side of the flat snap-fit ​​assembly extends to connect to an L-shaped extension block 6 to expand the frame's external connection function; the other side of the flat snap-fit ​​assembly integrates a pipe clamp device for easy installation and removal of pipe fittings.

[0030] The side of the lightweight keel 1 has markings 11, which facilitates measurement during installation. During implementation, a single frame is pre-assembled on the ground first. Right-angle nodes are positioned using the quick-locking triangular snap-fit ​​components. Then, two frames are installed with flat snap-fit ​​components and symmetrically connected using flat snap-fit ​​bases 5. Simultaneously, pipe clamp components and L-shaped extension blocks 6 can be installed together. The flat snap-fit ​​components are installed on the lightweight keel 1 without immediate fixation. The flat snap-fit ​​base 5 is placed on one side of the flat snap-fit ​​component and pre-tightened. The same process is repeated on the other side. The flat snap-fit ​​component is installed first, then the other side of the flat snap-fit ​​base 5 is placed on one side of the flat snap-fit ​​component, and the entire assembly is tightened. The other side is then fully tightened. The L-shaped extension blocks 6 are also pre-installed with the flat snap-fit ​​components first, then the extension blocks are installed, and finally, both are tightened together.

[0031] The symmetrically distributed lightweight keel 1, combined with triangular and flat snap-fit ​​components, enables modular and rapid assembly of the frame, simplifying the assembly process and reducing time and labor costs. The presence of graduated markings 11 provides construction workers with an intuitive measurement benchmark, allowing for quick determination of cutting and connection positions, significantly improving installation accuracy and reducing manual measurement errors. The combination of pipe clamp components and flat snap-fit ​​components enables rapid installation of pipe fittings, reducing secondary processing.

[0032] The triangular buckle assembly includes two first connectors 2. Both sides of the first connectors 2 are provided with flanges 24, which correspond to the lightweight keel. One side of each of the two first connectors 2 is provided with a slot 21 and a hook 22, with one slot 21 corresponding to the other hook 22. One side of the first connectors 2 is provided with a protrusion 23, and the middle of the two first connectors 2 is provided with a mounting hole 26.

[0033] The triangular buckle assembly consists of two symmetrical first connectors 2. Each connector has a flange 24 on both sides where it connects to the lightweight keel 1. The flange 24 bends inward, and the inward part can just fit into the recess of the lightweight keel 1 to achieve positioning and fixation. The mating ends of the two connectors are respectively provided with slots 21 and hooks 22. The two first connectors 2 are slightly offset, and then the hooks 22 are inserted into the corresponding slots 21. Then the two first connectors 2 are moved to align, and they are locked in place. The protrusion 23 has reinforcing ribs inside to improve the overall compressive strength of the connector. The mounting hole 26 is located in the central area of ​​the connector. Bolts can be screwed into the mounting hole 26 to achieve axial fastening by bolts that pass through the two connectors. During assembly, the two first connectors 2 are first mated together, and then the flanges 24 of the connectors are inserted into the recesses of the lightweight keel 1. After installation, the bolts are used to achieve rigid fixation. By using split, symmetrical connectors, the snap-fit ​​components can be pre-assembled on-site before being fully embedded into the keel, improving overall assembly efficiency compared to welding. This allows for rapid installation and disassembly, simplifying the assembly process and reducing time and labor costs.

[0034] The slot 21 is divided into a long slot and a short slot. The hook 22 is L-shaped. The horizontal length of the hook 22 corresponds to the length of the long slot of the slot 21, and the vertical length of the hook 22 corresponds to the length of the short slot of the slot 21. Multiple teeth 25 are provided on one side of the flange 24.

[0035] When personnel want to engage the two first connectors 2, first align the horizontal portion of the hook 22 with the long slot of the groove 21, ensuring that both hooks 22 and both grooves 21 are aligned. Then, insert the hook 22 into the groove 21. Initially, the two connectors are inserted in a staggered manner. After insertion, move one of the first connectors 1 to align the two connectors. Once the hook 22 is inserted into the groove 21, its vertical portion is inside the groove 21. After moving one of the first connectors 2, the vertical portion of the hook 22 moves within the groove 21 until it engages with the short slot of the groove 21, pressing against the inner side of the first connector 2, thus securing it. To disassemble, simply pull in the opposite direction. The hook 22 is a straight hook, which is simpler to manufacture than a curved hook. The teeth 25 primarily increase the friction at the connection point with the lightweight keel 1, making the overall structure more stable. With hooks 22 and slots 21, quick installation and disassembly can be achieved without additional tools, simplifying the assembly process and reducing time and labor costs.

[0036] The planar snap-fit ​​assembly includes two second connectors 3, which are a long block and a short block, respectively. The two second connectors 3 are stacked to form a receiving cavity. The sides of the two second connectors 3 are provided with bent blocks. The receiving cavity and the bent blocks correspond to the lightweight keel 1. A circular groove 31 is opened inside one of the second connectors 3. A tension ring 32 is connected to one side of the circular groove 31. The inner side of the tension ring 32 is provided with threads. An elliptical groove is opened inside the other second connector 3.

[0037] The planar snap-fit ​​assembly consists of two second connecting parts 3, a long block and a short block, which, when stacked, form a receiving cavity that matches one side of the lightweight keel 1. The short block has a circular groove 31 and a tension ring 32 with internal threads for fixed connection, while the long block has an elliptical groove. The two connecting parts are fixed by tightening the threads. The bending angle of the two side blocks matches the recessed structure of the outer wall of the keel. During assembly, the long block and the short block are first stacked so that the bending block is embedded in the recess of the keel. Then, the bolt is passed through the elliptical groove and the circular groove 31 and screwed into the interior of the tension ring 32. The tension ring 32 protrudes outward by 2.5mm. The tension ring 32 can replace the nut, meaning that only the bolt needs to be screwed in during fixing, without the need for a nut, reducing materials and saving costs.

[0038] A V-shaped block 34 is provided on one side of each of the two second connectors 3, and a protrusion 33 is provided on one side of one of the second connectors 3.

[0039] By incorporating V-blocks 34, which provide a guiding function, the two second connectors 3 can be fully overlapped by partially overlapping the V-blocks 34, eliminating the need for further adjustments. The position of the V-blocks 34 restricts the overlap of the two second connectors 3, thus enabling faster assembly. Reinforcing ribs are also added inside the second protrusion 33 to enhance overall pressure resistance.

[0040] The pipe clamp assembly includes two clamping blocks 4, and fastening components are provided on the sides of both clamping blocks 4. A limit block 42 is connected to one side of one clamping block 4, and a threaded rod 43 is connected to one side of the limit block 42. The threaded rod 43 corresponds to the tension ring 32.

[0041] Personnel can fix the pipe clamp assembly by screwing the threaded rod 43 into the tension ring 32 of the flat snap-fit ​​assembly. The threaded rod 43 can be screwed in directly; because of the tension ring 32, no additional nut is needed. Once fully screwed in, it presses against the limiting block 42, thus ensuring overall stability. When installing tubular components, the tubular component is inserted between the two clamping blocks 4 and then secured using the fastening assembly. The tension ring 32 and threaded rod 43 enable quick installation of tubular components, improving overall installation efficiency.

[0042] The fastening assembly includes a bolt 41 and a nut. The bolt 41 and the two clamping blocks 4 are threaded together on the inside of their sides. The nut and bolt 41 are also threaded together.

[0043] After the tubular component is placed in the middle of the two clamping blocks 4, the initial fastening components are not tightened but loose. After placement, the two clamping blocks 4 are tightened by the cooperation of the bolts 41 and nuts, thus completing the fixation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
