Description

Technical Field

[0001] This invention relates to the field of ceiling joist technology, specifically a concealed, heat-insulating, and anti-condensation ceiling joist. Background Technology

[0002] Ceiling joists are the main material used in suspended ceilings. They connect to the hangers and provide installation nodes for the ceiling panels, acting as a crucial link between the ceiling and the ceiling structure. Ceiling joists are generally classified into light steel joists, wooden joists, and aluminum alloy joists. Among them, light steel joists, made from cold-rolled galvanized steel strips through a cold bending process, offer advantages such as lightweight yet high strength, good fire resistance, moisture and corrosion resistance, environmental friendliness, and convenient construction, making them the most widely used ceiling joist material on the market.

[0003] Currently, the main material for ceiling joists is usually lightweight steel. Due to the characteristics of its metallic material, its thermal insulation is poor during use, especially when there is a significant temperature drop. Moisture will condense on the surface of the steel, and the condensed water will accumulate and form water droplets or streams that fall onto the ceiling panels. Prolonged contact with condensation can easily cause deformation or mold growth on the panels. At the same time, if the joists are frequently in a condensed and humid environment, the galvanized layer on the surface is easily damaged, leading to rust and reducing the load-bearing capacity and service life of the joists. In view of the above-mentioned technical defects of the existing technology, an invisible thermal insulation and anti-condensation ceiling joist is provided to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an invisible, heat-insulating, and anti-condensation ceiling joist to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A concealed, heat-insulating, anti-condensation ceiling joist includes a horizontal frame. Longitudinal rods I are fixed to both ends of the horizontal frame. A longitudinal rod IV is fixed to the middle of the horizontal frame. Suspension square tubes II are fixed to both ends of the longitudinal rod IV. A suspension square tube I parallel to the suspension square tube II is fixed between the two longitudinal rods I at each end of the horizontal frame. Mounting plates are fixed to the tops of both the suspension square tubes I and II. Reinforcing members are installed between the longitudinal rod IV and the two longitudinal rods I. Adjustable square tubes are slidably sleeved at the lower parts of both the suspension square tubes I and II. Two heat-insulating covers are installed on the suspension square tubes I, connected by bolts and nuts.

[0010] As an improvement of the present invention: a through hole is provided on the side wall of the heat insulation cover, and a friction column that slidably contacts the side wall of the telescopic cover is slidably installed in the through hole. A sleeve is fixed on the heat insulation cover, and a push spring is fixed between the sleeve and the friction column.

[0011] As an improvement of the present invention: the side wall of the telescopic cover is fixed with a guide strip block that is slidably embedded in the inner wall of the heat insulation cover.

[0012] As an improvement of the present invention: the reinforcing member includes a tie rod, the two ends of which are fixed to the longitudinal rod II and the longitudinal rod III respectively, and a transverse rod parallel to the cross frame is fixed between the suspended square tube II and the suspended square tube I.

[0020] First embodiment: Please refer to the appendix Figure 1 -Appendix Figure 8 An invisible heat-insulating and anti-condensation ceiling keel includes a horizontal frame 12. Both ends of the horizontal frame 12 are fixed with longitudinal rods I13. The middle of the horizontal frame 12 is fixed with a longitudinal rod IV23. Both ends of the longitudinal rod IV23 are fixed with suspended square tubes II14. A suspended square tube I3 parallel to the suspended square tube II14 is fixed between the two longitudinal rods I13 at each end of the horizontal frame 12. The top of the suspended square tubes I3 and II14 is fixed with mounting plates 6. Reinforcing members are installed between the longitudinal rods IV23 and the two longitudinal rods I13. Adjustable square tubes 7 are slidably sleeved on the lower part of the suspended square tubes I3 and II14. Two heat-insulating covers 1 are installed on the suspended square tubes I3. The two heat-insulating covers 1 are connected by bolts and nuts. A telescopic cover 2 is slidably installed on the bottom of each heat-insulating cover 1. The telescopic cover 2 is sleeved on the adjustable square tube 7.

[0021] When in use, this ceiling keel is fixed to the ceiling of the building through the mounting plate 6 fixed to the top of the suspended square tube I3 and suspended square tube II14 via connectors, thus suspending and fixing the suspended square tube I3 and suspended square tube II14. The longitudinal rod I13 and the cross frame 12 are suspended by the suspended square tube I3 and suspended square tube II14. The adjustable square tube 7 installed at the bottom of the suspended square tube I3 and suspended square tube II14 extends to the bottom of the telescopic cover 2. The mounting plate 8 at the bottom of the adjustable square tube 7 is connected and fixed to the gypsum board or decorative panel used for ceiling decoration, thereby achieving the ceiling decoration effect.

[0022] The insulation cover 1 and telescopic cover 2 installed in this ceiling keel provide excellent coverage for the connecting components such as the horizontal frame 12, longitudinal rod I13 and longitudinal rod III17. This not only provides a good concealing effect and enhances the aesthetics, but also provides thermal insulation for the steel, preventing condensation on the surface of the steel material due to large temperature differences. This also prevents water droplets from corroding the connecting components and prevents condensation from causing mold and deformation of the ceiling decorative panels.

[0023] The top of the insulation cover 1 is provided with a slot I5. The suspension square tube I3 is slidably adapted to the slot I5. A limiting piece 4 located above the insulation cover 1 is fixed on the suspension square tube I3. A longitudinal rod III17 located above the longitudinal rod I13 is fixed on the suspension square tube I3. The longitudinal rod III17 abuts against the inner top of the insulation cover 1.

[0024] During the docking process of the two insulation covers 1, the suspended square tube I3 slides along the slot I5. After the two insulation covers 1 are docked, they are locked and fixed by bolts and nuts. The limiting piece 4 and the longitudinal rod III17 are used to position the insulation cover 1 in a vertical position to ensure its stable position after installation.

[0025] The bottom of the telescopic cover 2 of this ceiling keel has a slot II11. The adjusting square tube 7 slides and adapts to the slot II11. An X-shaped connecting bracket 9 is fixed between the adjusting square tubes 7 to support the telescopic cover 2. The X-shaped connecting bracket 9 not only connects and fixes multiple adjusting square tubes 7, but also supports the telescopic cover 2, so that when the adjusting square tubes 7 slide vertically, the telescopic cover 2 automatically adjusts its height, ensuring that the space enclosed by the telescopic cover 2 and the insulation shell 1 can adapt to the height changes of the mounting plate 8.

[0026] A locking stud 26 is threaded onto the side wall of the adjusting square tube 7. One end of the locking stud 26 abuts against the suspension square tube I3, and a screw block 22 is fixed to the other end of the locking stud 26. A mounting plate 8 is fixed to the bottom of the adjusting square tube 7. A base plate 25 is fixed to the bottom of the suspension square tube I3. A connecting spring 24 is installed inside the adjusting square tube 7. One end of the connecting spring 24 is fixed to the base plate 25, and the other end of the connecting spring 24 is fixed to the mounting plate 8.

[0027] The adjusting square tube 7 can slide vertically relative to the suspended square tube I3. By turning the screw block 22, the locking stud 26 is rotated, and the locking stud 26 locks and fixes the suspended square tube I3, ensuring the structural stability of the mounting plate 8 after the position is adjusted. The suspended square tube I3 and the mounting plate 8 are connected by the connecting spring 24, which can effectively prevent the adjusting square tube 7 from falling quickly during the adjustment process and improve the safety of the adjustment operation.

[0028] Additionally, a through hole 29 is provided on the side wall of the insulation cover 1. A friction post 28, which slidably contacts the side wall of the telescopic cover 2, is installed inside the through hole 29. A sleeve 10 is fixed on the insulation cover 1, and a push spring 27 is fixed between the sleeve 10 and the friction post 28. A guide strip 30, which is slidably embedded in the inner wall of the insulation cover 1, is fixed on the side wall of the telescopic cover 2.

[0029] With the above settings, under the elastic pushing action of the push spring 27, the friction column 28 rubs against the outer wall of the telescopic cover 2, so that during the vertical sliding adjustment of the telescopic cover 2 relative to the heat insulation cover 1, it has a good damping effect, making the temporary positioning of the telescopic cover 2 after adjustment and the height adjustment of the mounting plate 8 more stable and precise.

[0030] Second embodiment: Please refer to the appendix Figure 1 -Appendix Figure 8 Based on the first embodiment, the reinforcing member further includes a diagonal tie rod 16, with both ends of the diagonal tie rod 16 fixed to longitudinal rod II15 and longitudinal rod III17 respectively. A transverse rod 19 parallel to the crossbeam 12 is fixed between the suspension square tube II14 and the suspension square tube I3. The reinforcing member also includes two support rods I18 and two support rods II21. The lower end of the support rod I18 is fixed to the suspension square tube I3, and the lower end of the support rod II21 is fixed to the suspension square tube II14. The support rods I18 and II21 extend obliquely upwards, and their upper ends are welded and fixed to the diagonal tie rod 16.

[0031] The horizontal frame 12, longitudinal rod I13, longitudinal rod IV23 and horizontal rod 19 in this ceiling keel form a grid-shaped frame. The vertical structural extension is achieved through longitudinal rod III17 and longitudinal rod II15 to obtain a stable three-dimensional spatial structure. The diagonal tie rod 16 connects longitudinal rod II15 and longitudinal rod III17, and plays a good role in lateral tensile resistance. The diagonal tie rod 16 is supported by support rod II21 and support rod I18, which further ensures the structural stability of this ceiling keel.

[0032] In addition, a connecting rod 20 is fixed between the suspended square tube I3 and the longitudinal rod III17. The connecting rod 20 is located between the longitudinal rod I13 and the longitudinal rod III17. The connecting rod 20 connects the longitudinal rod III17 and the suspended square tube I3, which improves the suspension stability of the suspended square tube I3 and effectively ensures the structural strength of this ceiling joist.

[0033] In summary, the present invention, through the insulated cover 1 and the telescopic cover 2, effectively encloses the connecting components such as the cross frame 12, longitudinal rod I13, and longitudinal rod III17. This not only provides excellent concealment, enhancing the aesthetics of the ceiling decoration, but also insulates the steel, preventing condensation on the steel surface due to large temperature variations. It also effectively protects the ceiling panels, preventing mold, discoloration, or deformation, and prevents damage to the galvanized layer on the steel surface, thus providing excellent rust prevention and ensuring the load-bearing capacity and service life of the keel. The reinforcing components in this invention provide a reliable connection for the suspended square tube I3, suspended square tube II14, longitudinal rod I13, longitudinal rod III17, and crossbeam 12, ensuring the overall rigidity of the ceiling keel. The telescopic cover 2 can slide vertically relative to the insulation cover 1. After the installation position of the mounting plate 8 is adjusted, the telescopic cover 2 and the insulation cover 1 can adapt to the height changes of the mounting plate 8, and still provide insulation, concealment, and anti-condensation effects for the connecting components such as the longitudinal rod I13, longitudinal rod III17, and crossbeam 12, demonstrating high adaptability.
