Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a green and environmentally friendly ceiling light steel keel fastening structure for building engineering. Background Technology

[0002] In the field of building construction, suspended ceilings, as an important component of interior decoration and functional design, directly affect the overall performance and lifespan of a building due to their construction quality and stability. Light steel keel systems are widely used in suspended ceiling structures due to their advantages such as light weight, high strength, and convenient installation. However, existing light steel keel fastening structures still have many shortcomings in practical applications. For example, traditional fastening methods rely heavily on bolts and nuts for fixing. This connection method is not only cumbersome to operate, but also prone to loosening due to vibration or external forces during long-term use, affecting the stability and safety of the suspended ceiling. Furthermore, existing keel connection nodes often lack effective limiting and anti-loosening designs, which may lead to displacement or deformation under complex stress environments, thus affecting the reliability of the overall structure. At the same time, the installation process of traditional fastening structures often requires high construction precision and considerable manual intervention, increasing construction difficulty and cost, and making it difficult to meet the requirements of modern buildings for green environmental protection and energy efficiency. Therefore, developing a light steel keel fastening structure that is simple in structure, easy to install, and possesses high stability and anti-loosening performance has become a pressing technical challenge in the current building construction field. This utility model aims to overcome the above-mentioned problems through innovative design concepts and technical means, and provide a more reliable and efficient solution for the fastening of ceiling light steel keel. Utility Model Content

[0003] This utility model aims to solve the problems of poor connection reliability, complex installation, and insufficient structural stability in existing ceiling light steel keel fastening structures, and provides a green and environmentally friendly ceiling light steel keel fastening structure for building engineering. The fastening structure achieves high efficiency, stability, and environmental friendliness by optimizing the connection methods between the main keel, vertical keel, secondary keel, and horizontal keel, and by adding auxiliary fixing mechanisms.

[0004] This utility model provides a green and environmentally friendly ceiling light steel keel fastening structure for building engineering, including main keel, vertical keel, secondary keel, horizontal keel, hanger, contour piece, fastening main plate, first covering piece, second covering piece, reinforcing rod, side block, and limiting block. The main keel is arranged horizontally to form a basic frame, with several equidistantly distributed keel holes for inserting contour pieces to connect with the secondary keels. The vertical keel is arranged perpendicular to the main keel, intersecting with it to form a grid structure. Its top has a rectangular positioning groove for engaging with the positioning strip at the bottom of the second covering piece, limiting vertical displacement and enhancing overall stability. The secondary keel is located between the main keel and the vertical keel, serving as a connector and support. Part of it is embedded in the first groove on the fastening main plate to ensure horizontal fixation. The horizontal keel is arranged horizontally below the secondary keel, further enhancing structural stability. Part of it is embedded in the second groove on one side of the first covering piece to ensure a tight connection between the horizontal keel and the secondary keel.

[0005] Furthermore, the conforming component comprises an integrally formed horizontal plate and two symmetrically arranged cylindrical portions. The horizontal plate supports and secures the main plate, while the cylindrical portions have a first inner groove containing a sliding connecting block. One end of the connecting block is fixedly connected to the side wall of the first inner groove via a first spring. When the conforming component is inserted into the keel hole on the main keel, the connecting block is compressed inward due to its inclined design. After entering the first inner groove, it pops out under the action of the first spring and contacts the inner wall of the main keel, thereby achieving locking. In particular, the top of the main plate has an integrally formed mating block with a locking hole inside. This locking hole corresponds to the through hole on the conforming component, allowing the mounting hole on the connecting block to be aligned and fixed with the through hole and locking hole using bolts or pins, further improving connection reliability.

[0006] Furthermore, the hanger is fixed to the top of the main keel to suspend the entire ceiling structure and is connected to the main keel via reinforcing rods. The reinforcing rods are inclinedly arranged on both sides of the hanger, fixed with nuts and bolts, and connected to the top of the main keel via countersunk bolts to distribute the load and enhance overall strength. The side block is fixed to one side of the top of the vertical keel and has a second inner groove. A limit block is slidably connected within the second inner groove, and one end of the limit block is fixedly connected to the side wall of the second inner groove via a second spring. When the positioning strip at the bottom of the second covering is inserted into the positioning groove at the top of the vertical keel, the limit block is compressed into the second inner groove due to its inclined design. After the positioning strip is fully inserted, the limit block pops out under the action of the second spring and contacts the positioning strip, thus achieving an elastic locking function.

[0007] Specifically, the first covering component is pressed against one side of the horizontal keel, and its side near the top is fixedly connected to the fastening main plate to support the secondary keel; the second covering component is pressed against one side of the secondary keel, and a connecting block is fixedly installed on its side near the top, with symmetrically arranged mounting holes on the connecting block. By aligning and fixing the mounting holes with the through holes on the contoured component and the snap holes on the fastening main plate, a multi-layered connection between the main keel, secondary keel, and horizontal keel is achieved. Furthermore, both the first and second covering components are made of light steel, possessing high bending strength and corrosion resistance, while also conforming to green environmental protection principles.

[0008] This utility model, through the aforementioned structural design, achieves a multi-level locking mechanism, significantly improving the reliability of the connection between keels. Specifically, the locking block design of the contoured component, combined with the elastic effect of the first spring, allows the contoured component to automatically lock after being inserted into the keel hole of the main keel, avoiding the risk of loosening; the locking holes on the fastening main board are aligned with the through holes on the contoured component and fixed with bolts, forming a stable mechanical connection; the cooperation between the limiting block and the positioning strip further enhances the connection strength between the vertical keel and the second covering component.

[0009] Furthermore, this utility model adopts a modular design, and the components can be assembled by simple plug-in or bolt fixing, which greatly simplifies the construction process. The specific steps are as follows: S1, arrange multiple main keels horizontally and fix them to the top of the building, ensuring that the keel holes are aligned; S2, insert the profiled part into the keel hole of the main keel, and use the synergistic action of the locking block and the first spring to achieve initial locking; S3, place the fastening main plate on the horizontal plate of the profiled part, and align the locking hole on the connecting block with the through hole on the profiled part; S4, embed part of the secondary keel into the first groove of the fastening main plate, and fix the mounting hole, through hole and locking hole on the connecting block with bolts; S5, embed part of the horizontal keel into the second groove on one side of the first covering part, and fix the first covering part to the fastening main plate with bolts; S6, press the second covering part onto one side of the secondary keel, so that the positioning strip at its bottom is inserted into the positioning groove at the top of the vertical keel, and achieve locking through the elastic action of the limiting block and the second spring; S7, arrange the reinforcing rods obliquely on both sides of the hanging part, and fix them to the top of the main keel with nuts, bolts and countersunk bolts to complete the assembly of the overall structure.

[0010] Specifically, this invention enhances the overall structure's resistance to deformation and its load-bearing capacity through the synergistic effect of the reinforcing rods, the fastening main plate, and the covering components. The inclined arrangement of the reinforcing rods effectively disperses the load borne by the ceiling structure, preventing localized stress concentration. The interlocking design of the first groove of the fastening main plate with the secondary keel, and the interlocking design of the second groove of the first covering component with the horizontal keel, both provide excellent support. The pressing action of the first and second covering components further ensures a tight connection between the keels, reducing the risk of loosening due to vibration or external forces.

[0011] Furthermore, all materials used in this invention are recyclable light steel, conforming to the concept of green environmental protection and reducing resource consumption and environmental pollution during construction. Light steel not only possesses high strength and rigidity but also excellent corrosion resistance and machinability, meeting the needs of various construction projects.

[0012] In summary, the ceiling light steel keel fastening structure provided by this utility model solves the problems of poor connection reliability, complex installation, and insufficient structural stability in the prior art by optimizing the connection method, adding auxiliary fixing mechanism, and adopting modular design. It has significant technical advantages and application value and is suitable for various building engineering projects.

[0025] Please refer to Figure 1 to Figure 8 This utility model provides a green and environmentally friendly ceiling light steel keel fastening structure for building engineering. Its core lies in the synergistic effect of components such as the main keel 1, vertical keel 100, secondary keel 2, horizontal keel 4, hanging parts 3, contouring parts 6, fastening main plate 11, first covering part 10, second covering part 15, reinforcing rod 5, side block 16, and limiting block 18, achieving efficient, stable, and environmentally friendly performance. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] A side block 16 is fixed to the side of the vertical keel 100 near the top with screws. A second inner groove 22 is opened inside the side block 16. A limiting block 18 with one side inclined is slidably connected inside the second inner groove 22. One end of the limiting block 18 is fixedly connected to one end of a second spring 23. The other end of the second spring 23 is fixedly connected to the side wall of the second inner groove 22 by a buckle.

[0027] like Figure 1The basic frame of the entire suspended ceiling structure shown consists of main keel 1 and vertical keel 100. The main keel 1 is arranged horizontally and fixed to the building ceiling by hangers 3. The vertical keel 100 is arranged perpendicular to the main keel 1 and intersects with the main keel 1 to form a grid structure. The main keel 1 has several keel holes 8 arranged in an array and evenly distributed for inserting the contour piece 6 to achieve connection with the secondary keel 2. The top of the vertical keel 100 has a rectangular positioning groove 19 for cooperating with the positioning strip 17 at the bottom of the second covering piece 15 to limit vertical displacement and enhance overall stability. The secondary keel 2 is located between the main keel 1 and the vertical keel 100, serving as a connection and support. Its part is embedded in the first groove 14 on the fastening main plate 11 to ensure the fixation of the secondary keel 2 in the horizontal direction. The horizontal keel 4 is arranged horizontally below the secondary keel 2 to further enhance structural stability. Its part is embedded in the second groove on one side of the first covering 10 to ensure a tight connection between the horizontal keel 4 and the secondary keel 2.

[0028] The design of the contouring component 6 is one of the key parts of this utility model. Figure 7 The contouring component 6 shown consists of an integrally formed horizontal plate and two symmetrically arranged cylindrical sections. The horizontal plate is used to support and fasten the main plate 11. The cylindrical sections have a first inner groove 20 inside. A sliding connecting block 13 is located inside the first inner groove 20. The bottom of the block 13 is inclined. One end of the block 13 is fixedly connected to one end of a first spring 21. The other end of the first spring 21 is fixedly connected to the side wall of the first inner groove 20 through a buckle. One end of the block 13 is fixedly connected to the side wall of the first inner groove 20 through the first spring 21. When the contouring component 6 is inserted into the keel hole 8 on the main keel 1, the block 13 is squeezed inward due to its inclined design and retracts into the first inner groove 20. Afterward, it pops out under the action of the first spring 21 and contacts the inner wall of the main keel 1, thereby achieving the locking function. In addition, the top of the fastening main board 11 is provided with an integrally formed docking block 7. The docking block 7 has a locking hole 12 inside. The locking hole 12 corresponds to the through hole 61 on the contour part 6, so that the mounting hole 91 on the connecting block 9 can be aligned and fixed with the through hole 61 and the locking hole 12 by bolts or pins, further improving the connection reliability.

[0029] Hanger 3 is fixed to the top of the main keel 1 to suspend the entire ceiling structure and is connected to the main keel 1 via reinforcing rod 5. For example... Figure 3The reinforcing rods 5 shown are obliquely arranged on both sides of the hanger 3 and fixed by nuts and bolts. They are also connected to the top of the main keel 1 by countersunk bolts to distribute the load and enhance the overall strength. Both sides of the hanger 3 are fixed with oblique reinforcing rods 5 by nuts and bolts. One end of the reinforcing rod 5 is fixedly connected to the top of the main keel 1 by a countersunk bolt. The side block 16 is fixed to one side of the top of the vertical keel 100 and has a second inner groove 22 inside. A limiting block 18 is slidably connected within the second inner groove 22. One end of the limiting block 18 is fixedly connected to the side wall of the second inner groove 22 by a second spring 23. When the positioning strip 17 at the bottom of the second covering 15 is inserted into the positioning groove 19 at the top of the vertical keel 100, the limiting block 18 is compressed into the second inner groove 22 due to its inclined design. After the positioning strip 17 is fully inserted, the limiting block 18 pops out under the action of the second spring 23 and contacts the positioning strip 17, thereby realizing the elastic locking function. The side block 16 has a second inner groove 22 inside, and a limiting block 18 with one side inclined is slidably connected inside the second inner groove 22. One end of the limiting block 18 is fixedly connected to one end of the second spring 23, and the other end of the second spring 23 is fixedly connected to the side wall of the second inner groove 22 by a buckle.

[0030] The first covering 10 is pressed against one side of the horizontal keel 4, and its side near the top is fixedly connected to the fastening main plate 11 to support the secondary keel 2. The second covering 15 is pressed against one side of the secondary keel 2, and its side near the top is fixedly provided with a connecting block 9. The connecting block 9 has symmetrically arranged mounting holes 91. The mounting holes 91 are aligned and fixed with the through holes 61 on the contour piece 6 and the snap holes 12 on the fastening main plate 11, realizing a multi-layer connection between the main keel 1, the secondary keel 2 and the horizontal keel 4. Both the first covering 10 and the second covering 15 are made of light steel, which has high bending strength and corrosion resistance, and conforms to the concept of green environmental protection.

[0031] This invention significantly improves the reliability of the connection between keels through a multi-level locking mechanism. The design of the locking block 13 of the contoured part 6, combined with the elasticity of the first spring 21, allows the contoured part 6 to automatically lock after being inserted into the keel hole 8 of the main keel 1, avoiding the risk of loosening. The locking hole 12 on the fastening main plate 11 is aligned with the through hole 61 on the contoured part 6 and fixed with bolts to form a stable mechanical connection. The cooperation between the limiting block 18 and the positioning strip 17 further enhances the connection strength between the vertical keel 100 and the second covering part 15.

[0032] The assembly process is as follows: S1. Arrange multiple main keels 1 horizontally and fix them to the building roof, ensuring the keel holes 8 are aligned. S2. Insert the profile 6 into the keel holes 8 of the main keel 1, using the cooperation of the locking block 13 and the first spring 21 to achieve initial locking. S3. Place the fastening main plate 11 on the horizontal plate of the profile 6 and align the locking hole 12 on the connecting block 7 with the through hole 61 on the profile 6. S4. Embed a portion of the secondary keel 2 into the first groove 14 of the fastening main plate 11, and fix the mounting hole 91 on the connecting block 9 with the through hole 61 and the locking hole 12 using bolts. S5. Embed a portion of the horizontal keel 4 into the second groove on one side of the first covering 10, and fix the first covering 10 to the fastening main plate 11 using bolts. S6 Press the second covering 15 against one side of the secondary keel 2 so that the positioning strip 17 at its bottom is inserted into the positioning groove 19 at the top of the vertical keel 100 and locked by the elastic action of the limiting block 18 and the second spring 23. S7 Arrange the reinforcing rod 5 obliquely on both sides of the hanger 3 and fix it to the top of the main keel 1 with nuts, bolts and countersunk bolts to complete the assembly of the overall structure.

[0033] This invention enhances the overall structure's resistance to deformation and its load-bearing capacity through the synergistic effect of the reinforcing rod 5 securing the main board 11 and the covering components. The inclined arrangement of the reinforcing rod 5 effectively disperses the load borne by the ceiling structure, avoiding localized stress concentration. The fitting design of the first groove 14 of the main board 11 with the secondary keel 2 and the fitting design of the second groove of the first covering component 10 with the horizontal keel 4 both provide excellent support. The pressing action of the first covering component 10 and the second covering component 15 further ensures a tight connection between the keels, reducing the risk of loosening due to vibration or external forces.

[0034] All materials are made of recyclable light steel, conforming to green environmental protection principles while reducing resource consumption and environmental pollution during construction. Light steel not only possesses high strength and rigidity but also excellent corrosion resistance and workability, meeting the needs of various construction projects. The ceiling light steel keel fastening structure provided by this utility model solves the problems of poor connection reliability, complex installation, and insufficient structural stability in existing technologies by optimizing the connection method, adding auxiliary fixing mechanisms, and adopting a modular design. It has significant technical advantages and application value, and is suitable for various construction projects.
