Description

Technical Field

[0001] This utility model relates to the field of building ceiling technology, specifically a combined ceiling keel structure that facilitates internal wiring. Background Technology

[0002] Modular ceiling keel structures are the core support system for building ceilings, assembled from main keels and secondary keels. Due to their flexible assembly and disassembly and stable load-bearing capacity, they are widely used in various architectural spaces. Modern ceilings often integrate lighting, communication, and other equipment, requiring the laying of various cables in the keel area. Internal wiring thus becomes a crucial component of the ceiling system. Relying on the keel's own structure or available space to achieve neat wiring is a key aspect of ensuring both the ceiling's functionality and aesthetics.

[0003] Utility model patent CN215594570U discloses a corner keel for ceiling joists. This corner keel includes horizontal joists and corner keels for connecting multiple horizontal joists. Several sets of interlocking pieces are punched and bent on the vertical surface of the corner keel. Multiple connecting holes are provided on the interlocking pieces, which are connected to the horizontal joists via fasteners. The horizontal joists are C-shaped, and multiple mounting holes are provided on their two mounting surfaces. Fasteners pass through the mounting holes and connecting holes sequentially to fix the horizontal joists and interlocking pieces. This corner keel avoids the use of hanging plugs to connect to the horizontal joists during installation, simplifying the installation steps and saving installation costs associated with using hanging plugs. Furthermore, this corner keel has a simple structure and good stability.

[0004] The current ceiling keel uses angle keel. When the ceiling is equipped with electrical components such as lighting and communication, the related wires, network cables and other wires lack dedicated restraint and storage space. They can only be scattered randomly in the gaps between the keels or inside the cavity. This not only makes them prone to tangling and squeezing with the keel connection structure, but also causes messy and disorderly wiring due to the lack of directional restraint, which brings inconvenience to the later maintenance and replacement of wire harnesses. In view of this, we propose a combined ceiling keel structure that facilitates internal wiring. Utility Model Content

[0005] The purpose of this utility model is to provide a modular ceiling keel structure that facilitates internal wiring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A modular ceiling keel structure for easy internal wiring includes several parallel main keels and several secondary keels fixed horizontally at the bottom of the main keels. Several cable restraint assemblies are installed on the web of the main keels. Each cable restraint assembly includes a plate fixedly connected to the main keel, a restraint seat inserted into the plate, and a stop bar hinged to the front end of the restraint seat. A sleeve plate is installed at the rear end of the restraint seat, and the plate is inserted into the sleeve plate. Both the top and bottom edges of the front end of the restraint seat are provided with protrusions, and a space for restraining cables is formed between the two protrusions and the front end of the restraint seat. The bottom end of the stop bar is hinged to the protrusion at the bottom, and the top end of the stop bar is fitted with and passes through the protrusion at the top, and then threaded with a locking handle. The stop bar closes the opening of the restraint space formed between the two protrusions and the front end of the restraint seat.

[0007] Preferably, the main keel has a C-shaped or I-shaped cross-section, with the top and bottom ends of the main keel being flange portions and the middle part of the main keel being a web portion. A cavity is formed between the flanges and the web, and the insert plate is fixed on the cavity wall located in the cavity corresponding to the web portion. The cable restraint assembly is located inside the cavity. In this setup, the cable restraint components are hidden inside the main keel cavity, which provides enclosed protection for the cables without taking up extra space in the ceiling, and does not affect the load-bearing capacity of the keel itself.

[0008] Preferably, the insert plate has a vertical plate structure, and a base plate is fixed to the tail end of the insert plate. The insert plate is perpendicular to the base plate, and the tail end face of the base plate is attached to and tightly welded to the web plate of the main keel. In this setup, the contact area between the insert plate and the main keel is increased by the base plate, and the welding fixing method further improves the connection stability, ensuring that the cable restraint assembly is not easy to loosen after bearing the wire harness.

[0009] Preferably, the tail end face of the constraint seat is provided with a groove for installing the sleeve plate. The sleeve plate has a U-shaped sheet structure in cross-section. The U-shaped bent section of the sleeve plate is fixed to the bottom of the groove by screws. The U-shaped opening of the sleeve plate faces the insert plate. The insert plate can be inserted into the sleeve plate from the U-shaped opening of the sleeve plate. In this configuration, the U-shaped sleeve provides a stable insertion guide for the insert plate, and the screw fixing method facilitates the installation and replacement of the sleeve, realizing a detachable connection between the constraint seat and the insert plate.

[0010] Preferably, the beginning and end ends of the U-shaped opening of the sleeve plate are arc-shaped structures that are far apart from each other, the width of the sleeve groove is greater than the maximum width of the sleeve plate, the inner walls of the beginning and end ends of the U-shaped opening of the sleeve plate are provided with protruding ridges, and the left and right end faces of the insert plate are provided with several ridge grooves. When the insert plate is inserted into the sleeve plate, the protruding ridges can extend into the ridge grooves. In this design, the arc-shaped opening structure facilitates quick insertion of the insert plate, and the cooperation between the protruding ridge and the groove can limit the relative sliding between the insert plate and the sleeve plate, improving the positioning accuracy after the constraint seat is installed.

[0011] Preferably, a groove is provided at the first end face of the boss, and the bottom end of the stop rod extends into the groove in the boss located at the bottom position. A rotating shaft is provided at the bottom end of the stop rod in a radial through shape. The rotating shaft passes through the boss located at the top position and is rotatably connected to the boss. When the stop rod is moved to rotate around the rotating shaft, the top end of the stop rod can be fitted into the groove in the boss located at the top position. In this design, the groove provides a limiting space for the rotation of the stop lever, and the rotating shaft enables the stop lever to open and close flexibly, facilitating the quick placement and removal of cables and improving installation efficiency.

[0012] Preferably, the top outer surface of the stop bar is threaded, and the length of the stop bar is greater than the height of the constraint seat. When the stop bar is rotated so that the top end of the stop bar is fitted into the groove of the boss located at the top position, tightening the locking handle can make the bottom end of the locking handle abut against the top end of the boss located at the top position. In this configuration, the threaded structure works in conjunction with the locking handle to reliably lock the stop bar. The tightening force enhances the sealing of the confined space, preventing the wire harness from coming loose when the ceiling vibrates.

[0013] Preferably, an insulating sleeve is fitted and fixed on the outer side of the stop bar. Several partitions are integrally formed on the end face of the insulating sleeve near the constraint seat. The partitions are evenly spaced along the axial direction of the insulating sleeve, and a groove for accommodating cables is formed between two adjacent partitions. In this setup, the insulating sleeve prevents the wire harness from directly contacting the metal retainer, and the wire grooves formed by the partitions allow for the classified storage of multiple sets of cables, reducing wire harness tangling and friction damage.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This modular ceiling keel structure, which facilitates internal wiring, uses cable constraint components and the coordinated operation of insert plates, constraint seats, stops, and partitions within the components to stably confine various cables within the ceiling to dedicated cable trays and constraint spaces. This achieves orderly storage and isolation of cable bundles. At the same time, the opening, closing, and locking of the stops allow for flexible placement and fixation of cables. This solves the problems of messy, tangled, and squeezed cable bundles in existing keel structures and facilitates the later positioning and maintenance of specific cable bundles.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Please see Figures 1-6 A modular ceiling keel structure for easy internal wiring is described, with main keels 100 and secondary keels 110 as the core load-bearing frame. Several main keels 100 are arranged in parallel, while several secondary keels 110 are fixed to the bottom of the main keels 100 in a transverse manner, together forming the basic support structure of the ceiling. To achieve orderly storage of cables inside the ceiling, several cable restraint components 200 are specially installed on the web of the main keel 100. The cable restraint components 200 can centrally restrain the wires, network cables, and other cable bundles inside the ceiling, preventing the bundles from being scattered and tangled with the keel structure, and providing convenience for later maintenance.

[0017] like Figure 2 and Figure 3As shown, in this utility model, the installation base of the cable restraint assembly 200 consists of an insert plate 210 and a base plate 211. The insert plate 210 is a vertical plate, and its tail end is fixed with a base plate 211 perpendicular to itself. The base plate 211 and the insert plate 210 are vertically arranged and welded together, which can improve the installation stability of the cable restraint assembly 200. The tail end face of the base plate 211 is tightly attached to the web of the main keel 100 and fixed by welding. The cross-section of the main keel 100 can be C-shaped or I-shaped, with flanges at the top and bottom ends and a web in the middle. A cavity structure is formed between the flanges and the web. The cavity structure allows the assembly to not occupy extra space in the ceiling interlayer and does not affect the overall installation layout of the ceiling. At the same time, the insert plate 210 is fixed to the cavity wall at the corresponding web position in the cavity, so that the cable restraint assembly 200 is completely hidden inside the cavity.

[0018] like Figures 2-5 As shown, specifically in the cable constraint assembly 200, the constraint seat 220 is plugged into the insert plate 210 via a sleeve plate 222. A groove 221 is provided on the tail end face of the constraint seat 220. The groove 221 provides precise installation positioning for the sleeve plate 222, facilitating quick docking between the insert plate 210 and the sleeve plate 222. The groove 221 is used to install the sleeve plate 222, which is a U-shaped sheet structure. Its U-shaped bend is fixed to the bottom of the groove 221 with screws. The U-shaped sleeve plate 222 can form a wrap-around restraint on the insert plate 210 from both sides, improving the structural stability after the two are engaged. The screw fixing method facilitates the installation, disassembly, and subsequent maintenance and replacement of the sleeve plate 222. The U-shaped opening faces the insert plate 210, allowing the insert plate 210 to be smoothly inserted into the sleeve plate 222 from the opening.

[0019] Furthermore, to improve the connection stability and installation convenience of the insert plate 210 and the sleeve plate 222, the two ends of the U-shaped opening of the sleeve plate 222 are designed as mutually distant arc structures. The arc structure can reduce the resistance when the insert plate 210 is inserted and play a guiding role, so that the insert plate 210 can quickly and accurately enter the sleeve plate 222 and reduce the installation difficulty. The groove width of the sleeve groove 221 is greater than the maximum width of the sleeve plate 222. The adjustment space reserved in the sleeve groove 221 can accommodate the small errors in the installation process of the sleeve plate 222, improve the assembly flexibility, and ensure that the sleeve plate 222 can be stably fixed in the sleeve groove 221, reserving adjustment space for the installation of the sleeve plate 222. Meanwhile, the inner walls of both ends of the U-shaped opening of the sleeve plate 222 are provided with protruding ribs 2221, and the left and right end faces of the insert plate 210 are provided with several grooves 212. The fitting of the protruding ribs 2221 and the grooves 212 can effectively limit the relative sliding between the insert plate 210 and the sleeve plate 222, and prevent them from shifting when the ceiling vibrates. When the insert plate 210 is inserted into the sleeve plate 222, the protruding ribs 2221 will extend into the grooves 212, limiting the relative sliding between the two.

[0020] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the first end of the constraint seat 220 is the core area for cable constraint. Both the top and bottom edges of the constraint seat 220 are provided with protrusions 223. The constraint space formed by the two protrusions 223 and the first end of the constraint seat 220 can provide a dedicated area for the cable, preventing the cable from coming out of the constraint component. At the same time, it clarifies the placement range of the cable harness. The constraint space for accommodating the cable is naturally formed between the two protrusions 223 and the first end of the constraint seat 220. The stop lever 230 is hinged in this area, with its bottom end extending into the groove 2231 of the bottom boss 223. The groove 2231 can limit the end of the stop lever 230, ensuring that the stop lever 230 always stays within the preset trajectory during rotation, avoiding deviation and jamming. A rotating shaft 231 is radially passed through the bottom end, and the rotating shaft 231 also passes through the top boss 223 and is rotatably connected to it. The rotating shaft 231 realizes the flexible hinge between the stop lever 230 and the boss 223, allowing the stop lever 230 to easily rotate around the rotating shaft 231. When the stop lever 230 is turned to rotate around the rotating shaft 231, its top end can be fitted into the groove 2231 of the top boss 223, thereby closing the opening of the confined space.

[0021] like Figure 2 and Figure 6 As shown, it is worth noting that the top periphery of the stop bar 230 has a threaded structure, and its length is greater than the height of the constraint seat 220. The top end passes through the top boss 223 and is threadedly connected to the locking handle 232. The cooperation between the threaded structure and the locking handle 232 can make the locking handle 232 tightly abut against the top boss 223 through the tightening action, thereby reliably fixing the stop bar 230 and preventing the stop bar 230 from loosening on its own during the use of the suspended ceiling. Tightening the locking handle 232 will make the bottom end of the locking handle 232 abut against the top end of the top boss 223, thus achieving reliable fixing of the stop bar 230. In addition, an insulating sleeve 233 is fixedly fitted on the outside of the stop bar 230. The insulating sleeve 233 can effectively isolate the stop bar 230 from direct contact with the cable, play an insulating protection role, and reduce the safety hazards caused by cable wear and exposure. Several partitions 234 are integrally formed on the end face of the insulating sleeve 233 near the restraint seat 220. These partitions 234 are evenly spaced along the axis. The wire grooves 2341 formed by the partitions 234 can classify and store different types of cables, reduce the tangling and friction between cables, and facilitate the identification and maintenance of specific cables in the future. The wire grooves 2341 formed between adjacent partitions 234 can classify and store different types of cables. In this embodiment, the modular ceiling keel structure, which facilitates internal wiring, is used as follows: First, according to the ceiling installation size requirements, several main keels 100 are arranged in parallel and fixed in preset positions. Then, secondary keels 110 are fixed across the bottom of the main keels 100, completing the construction of the ceiling base frame. Next, the insert plate 210 with a base plate 211 is fixed to the web plate inside the cavity of the main keel 100 by welding. At the same time, the sleeve plate 222 is installed in the slot 221 of the constraint seat 220 with screws to complete the cable constraint. The components of component 200 are pre-assembled; then, the constraint seat 220 is inserted into the insert plate 210 through the sleeve plate 222, so that the protrusion 2221 in the sleeve plate 222 is embedded in the groove 212 of the insert plate 210 for positioning. Then, the stop bar 230 is rotated around the pivot 231 to open the constraint space, and various cables are sorted and placed into the cable groove 2341. Finally, the stop bar 230 is rotated so that the top end is fitted into the groove 2231 of the top protrusion 223, and the locking handle 232 is tightened to fix the stop bar 230, thus completing the constraint and fixation of the cables. The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
