Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and more specifically, to an adjustable ceiling keel connection device for interior decoration. Background Technology

[0002] In existing interior ceiling construction, the ceiling joists, as the main load-bearing and connecting structure, directly affect the overall flatness and aesthetics of the ceiling due to their installation accuracy. Traditional ceiling joists mostly use fixed connection structures, typically installed using screws, clips, or welding. These connection structures have poor adaptability in actual construction, especially when facing different room structures, inconsistent beam heights, or significant installation errors in the hangers. Fixed connections struggle to achieve precise height and angle adjustments, often requiring repeated measurements and reinstallation to correct the position, increasing construction complexity and labor costs.

[0003] Furthermore, traditional connectors are susceptible to stress deviations during installation, leading to localized ceiling subsidence or loosening of connections, thereby reducing the overall structural stability and safety. While some improved structures introduce detachable components, their adjustment range is limited, and their complex structure hinders rapid on-site positioning and assembly. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Example

[0032] The following is for reference Figures 1-6 As shown in the illustration, and further explained with reference to a specific embodiment, this embodiment provides an adjustable ceiling keel connection device for interior decoration, including a hanger 100. The hanger 100 is inverted U-shaped, and a partition 110 is welded onto the hanger 100. The partition 110 and the opening area of ​​the hanger 100 form a receiving space 120 for engaging the keel. A fixing member 200 for fixing the keel is provided at the receiving space 120 of the hanger 100. The hanger 100 can be made of galvanized cold-rolled steel or stainless steel to improve corrosion resistance.

[0033] The connection between the partition 110 and the hanger 100 can be made with a thickened folded edge or reinforced with ribs to increase local rigidity and prevent deformation under stress or compression.

[0034] The hanger rod 300 includes a sleeve 310 and a tie rod 320. The sleeve 310 is slidably inserted at the end of the hanger 100 away from its opening area, and the tie rod 320 is slidably inserted on the sleeve 310. A locking element 321 for fixing the tie rod 320 to the indoor floor slab is provided at the end of the tie rod 320 away from the hanger 100. In this embodiment, the locking element 321 can be an expansion bolt 3211 or other strong locking structure. To ensure reliable locking, the expansion bolt 3211 can be used in conjunction with the pre-embedded sleeve 310 or a metal base, and a washer can be provided on the locking surface to distribute the tension and avoid local stress concentration.

[0035] As an alternative embodiment, the locking element 321 can also be a chemical anchor, a welded flange, or an adjustable anchor to meet the installation requirements of different floor slab materials (concrete, steel structure, wood, etc.).

[0036] The pull rod 320 has external threads, and a pair of first nuts 322 are threaded onto the pull rod 320 and abut against both ends of the sleeve 310. By adjusting the relative position of the pair of first nuts 322 on the pull rod 320, the length of the pull rod 320 on the sleeve 310 can be adjusted. The sleeve 310 also has external threads, and a pair of second nuts 311 are threaded onto the sleeve 310 and clamped onto the hanger 100. By adjusting the relative position of the pair of second nuts 311 clamping the hanger 100 on the sleeve 310, the height of the hanger 100 can be finely adjusted.

[0037] In different embodiments, to prevent the first nut 322 and the second nut 311 from loosening, the first nut 322 and the second nut 311 are secured with self-locking nuts, spring washers or adhesive as alternative measures; when fine adjustment is required, the first nut 322 and the second nut 311 can be marked with scale rings or engravings, which makes it easy for construction personnel to accurately record and quickly restore the preset height, and improve the consistency of repeated installations.

[0038] One end of the pull strap 400 is fixedly connected to the pull rod 320 near its upper part, and is symmetrically arranged in pairs on both sides of the pull rod 320. The other end is fixedly tightened and fixed to the hanger 100. Specifically, the hanger 100 is welded with a latch 900, and the pull strap 400 passes through the latch 900. The pull strap 400 has multiple slots 410 along its length. The pull strap 400 passes through the hole 910 of the latch 900 and is provided with a barb 911. The barb 911 is used to engage with the slot 410 to lock the length of the pull strap 400.

[0039] The material of the pull strap 400 can be high-strength polyester tape or metal braided tape, depending on the requirements of the project for elongation and weather resistance; the welding position and number of the clasps 900 can be designed as a multi-point arrangement according to the load distribution to evenly distribute the tension, and the fit between the slot 410 and the barb 911 can be designed as a stepped engagement to achieve a more reliable anti-slip function.

[0040] Reference Figure 4 and Figure 5 As shown, the fastener 200 includes hooks 210, tie bolts 220, and a pair of third nuts 230. The hooks 210 are integrally mounted at the opening of the hanger 100 and hook onto the keel. The tie bolts 220 slide through the opening of the hanger 100 and are tightened by the pair of third nuts 230 to achieve a stable fixation. The hooks 210 can be designed with a right-angled triangle cross-section to prevent the keel from coming loose under vertical vibration. The diameter and material strength of the tie bolts 220 should match the ceiling load. If necessary, the tie bolts 220 can use a double-threaded section or a pre-tightening design to apply pre-tightening force after installation, improving the overall connection rigidity.

[0041] Reference Figure 4 As shown, the two side plates of the receiving space 120 of the hanger 100 are provided with receiving grooves 130, and a first spring piece 131 is provided in the receiving groove 130. The first spring piece 131 is used to abut against the keel. The first spring piece 131 can be made of spring steel sheet with good elasticity, which is stamped and heat treated to maintain its elastic recovery performance. It can be installed by snapping into the receiving groove 130 or by welding the two ends.

[0042] As an optional embodiment, the contact surface of the first spring 131 can be designed as toothed or arc-shaped to improve the anti-slip ability in contact with the keel and disperse the contact stress.

[0043] Additionally, a vertical perforation 111 is provided on the partition 110, and a second spring piece 140 is installed on the hanger 100. In its initial state, the second spring piece 140 extends out of the perforation 111 into the receiving space 120. Thus, the first spring piece 131 abuts against both sides of the keel, and the second spring piece 140 abuts against the top of the keel, achieving stable clamping and limiting. The part of the second spring piece 140 located in the perforation 111 can be designed in a U-shape to facilitate compression and provide abutment force when inserted into the keel.

[0044] Reference Figure 1 and Figure 4 As shown, the end of the pull rod 320 away from the locking member 321 is threaded with an abutment screw 500. The end of the abutment screw 500 is provided with an abutment plate 510, which is used to abut against the second spring piece 140. A rotating nut 520 is fixedly provided on the abutment screw 500 to facilitate the operator to rotate the abutment screw 500. After adjusting the relative position of the pull rod 320 and the sleeve 310, rotating the nut 520 drives the abutment plate 510 of the abutment screw 500 to abut against the second spring piece 140, so that the second spring piece 140 can abut against the keel more stably.

[0045] The contact surface of the abutment plate 510 can be padded with soft pads or elastic gaskets to avoid local damage to the second spring 140. The abutment screw 500 can also adopt a graduated fine-adjustment design to facilitate precise control of the clamping force.

[0046] Reference Figures 4-6 As shown, a smooth section 312 is provided on the sleeve 310. The diameter of the smooth section 312 is smaller than the diameter of the sleeve 310. A limiting sleeve 600 is fitted on the smooth section 312. The limiting sleeve 600 is fixedly connected to the hanger 100 through the support plate 610. A pair of symmetrical elongated holes 3121 are provided along the length direction of the sleeve 310 at the position of the smooth section 312. A wing nut 700 is threaded through the limiting sleeve 600. The wing nut 700 passes through one of the elongated holes 3121 and abuts against the abutting screw 500. The wing nut 700 can limit the abutting screw 500.

[0047] The smooth section 312 reduces friction and provides a precise sliding fit. The connection between the limiting cylinder 600 and the support plate 610 can be achieved by a combination of spot welding and riveting to improve torsional strength. The wing nut 700 serves as a manual limiting component, which facilitates quick on-site adjustment without tools. As an optional embodiment, the wing nut 700 can also be replaced with a hexagonal nut with a locking device to meet higher vibration resistance requirements.

[0048] Furthermore, a third spring plate 800 is installed in the elongated hole 3121 on the side away from the wing nut 700. The third spring plate 800 is used to abut against the abutting screw 500. The part of the third spring plate 800 that abuts against the abutting screw 500 is provided with a protrusion 811. The protrusion 811 can better abut against the threaded part of the abutting screw 500 to achieve more stable limiting. The protrusion 811 of the third spring plate 800 can be designed as V-shaped or crescent-shaped to conform to the thread shape and provide a self-locking effect. The material of the third spring plate 800 can be stainless steel with good elasticity to balance durability and elastic recovery.

[0049] As an alternative embodiment, the third spring 800 may also be designed as a replaceable metal spring.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
