Description

Technical Field

[0001] This utility model relates to the field of ceiling hanging technology, and in particular to a ceiling hanging structure and a ceiling using the same. Background Technology

[0002] As the core system for load-bearing and decoration in a building's interior space, the performance of the ceiling suspension structure directly affects the functionality, durability, and safety of the building space. Traditional ceiling suspension systems often employ a modular assembly structure composed of hangers, brackets, main joists, and secondary joists: the hangers, as vertical load-bearing components, are connected to the main building structure via expansion bolts or embedded parts, bearing the load transfer; the brackets, as connectors, fix the main and secondary joists in a vertically intersecting manner, forming a grid-like support system; the main joists, as longitudinal load-bearing components, and the secondary joists, which bear the lateral load distribution function, together constitute the basic framework of the ceiling. The core technology of this structure lies in the vertical connection stability of the main and secondary joists—if there is a deviation or looseness in the connection between the brackets and the joists, it will lead to an imbalance in the force distribution within the joist grid plane, causing the subsequently laid fireproof boards, ceiling decoration layers, etc., to form a fragile "floating" structure. This can result in minor issues such as wavy deformation of the board surface and cracking of joints, or even local or overall ceiling collapse, creating significant safety hazards.

[0048] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] A ceiling suspension structure includes a screw hanger 1, a hanger 2, a secondary keel 3, and a main keel 4;

[0053] The top end of the screw rod 1 is detachably connected to the external ceiling.

[0054] The bottom end of the screw rod 1 is detachably connected to the secondary keel 3;

[0055] The hanging bracket 2 is detachably connected to the main keel 4 and the secondary keel 3;

[0056] The hanging bracket 2 includes a hanging bracket body 21. The upper end of the hanging bracket body 21 is bent to form a hanging bracket slot 22 that matches the secondary keel 3. The hanging bracket body 21 has a limiting opening 23 that matches the main keel 4. The limiting opening 23 is connected to the lower end of the hanging bracket body 21.

[0057] The hanging bracket 2 is detachably hung on the secondary keel 3 through the hanging bracket slot 22, and the hanging bracket body 21 abuts against the secondary keel 3;

[0058] The main keel 4 is installed through and limited in the limiting port 23. The main keel 4 is located below the secondary keel 3, and the main keel 4 and the secondary keel 3 are arranged perpendicularly.

[0059] like Figure 1-7 As shown, this ceiling suspension structure achieves a vertically stable connection between the main keel 4 and the secondary keel 3 through a modular and detachable design. The top of the screw hanger 1 is detachably fixed to the ceiling, and the bottom end is connected to the secondary keel 3, forming a longitudinal support frame. The hanger 2 is hooked to the secondary keel 3 through the hanger slot 22 at its upper end, and the main keel 4 is laterally limited through the limiting slot 23, so that the main keel 4 and the secondary keel 3 form a stable frame that intersects vertically. More importantly, the hanger body 21 abuts against the secondary keel 3 to enhance stability, while the main keel 4 is limited through the limiting slot 23 to prevent lateral displacement, thereby ensuring the overall rigidity and load-bearing capacity of the ceiling structure.

[0060] In summary, the beneficial effects of this technical solution include:

[0061] 1. Improve vertical stability: The double limiting design of the hanging bracket 22 and the limiting port 23 of the hanging bracket 2 ensures a reliable connection between the main keel 4 and the secondary keel 3, solving the problem of ceiling deformation and cracking caused by keel spacing deviation or loose connection in traditional structures, and avoiding safety hazards.

[0062] 2. Simplified construction and maintenance: The overall detachable connection method supports modular installation and subsequent adjustments, reducing quality risks caused by uneven specifications or improper installation, while facilitating local repairs and replacements.

[0063] 3. Enhanced structural adaptability: The position of the main keel 4 can be precisely adjusted through the limiting port 23, which can adapt to the spacing of secondary keels 3 of different specifications, meet the load-bearing requirements of large-sized spaces or complex shapes, and break through the limitations of traditional ceilings.

[0064] To further explain, the cross-sectional shape of the limiting port 23 is T-shaped;

[0065] The cross-sectional shape of the main keel 4 is I-shaped;

[0066] The upper half of the main keel is inserted through and limited to the limiting port 23.

[0067] Specifically, such as Figure 1-2 and Figure 5As shown, precise positioning and load transfer are achieved through the cooperation of the T-shaped limiting port 23 and the I-shaped main keel 4. The limiting port 23 adopts a T-shaped opening design, with its top horizontal section matching the width of the main keel 4 and its bottom vertical section matching the thickness of the main keel 4. During installation, the upper half of the main keel 4 is vertically inserted into the limiting port 23. The horizontal section of the T-shaped opening forms a horizontal limiting effect on the main keel 4, while the vertical section contacts the main keel 4 and provides vertical support, significantly reducing the risk of lateral slippage or longitudinal deflection of the main keel 4, solving the hidden danger of easy loosening of traditional bolt connections, and avoiding instability of the ceiling structure caused by keel displacement.

[0068] To further explain, the main keel 4 includes two I-shaped keels 41 that are installed back-to-back;

[0069] The two ends of the I-shaped bone 41 are symmetrically provided with first connecting through holes 4a, and the first connecting through holes 4a are provided with mounting connectors 5.

[0070] Specifically, such as Figure 5 As shown, the main keel 4 adopts a composite structure of double I-shaped ribs 41 with back-to-back contact, and modular splicing and load transfer are achieved through the first connecting through hole 4a. The webs of the two I-shaped ribs 41 are relatively close together to form a superimposed I-shaped cross section, and their exposed flanges constitute the bearing surface of the main keel 4. During installation, the first connecting through holes 4a are symmetrically distributed at both ends of the I-shaped ribs 41, and the double I-shaped ribs 41 are laterally fixed by bolts, pins and other connecting parts 5 to form an integral load-bearing unit.

[0071] To further explain, the main keel 4 also includes an I-shaped bone brace 42;

[0072] The I-shaped bone brace 42 has two sets of second connecting through holes 4b symmetrically opened. The second connecting through holes 4b and the first connecting through holes 4a are arranged in a one-to-one correspondence. The connector 5 is installed through the second connecting through holes 4b and the first connecting through holes 4a.

[0073] Specifically, such as Figure 6 As shown, the I-shaped bone 41 achieves flexible length extension through the I-shaped bone bracket 42. When it is necessary to extend the main keel 4, the two ends of the prefabricated standard section of the I-shaped bone bracket 42 are respectively connected to the ends of the original main keel 4's I-shaped bone 41, so that the second connecting through hole 4b of the I-shaped bone bracket 42 is aligned with the first connecting through hole 4a of the original I-shaped bone 41. Then, high-strength bolts and other connecting parts 5 are used to pass through the two sets of through holes to form a rigid connection between the I-shaped bone bracket 42 and the original I-shaped bone 41.

[0074] To further explain, the secondary keel 3 includes an L-shaped bone 31, the cross-sectional shape of which is L-shaped;

[0075] The horizontal section of the L-shaped bone 31 is provided with a third connecting through hole 3a, which is used for detachable connection with the bottom end of the screw rod 1.

[0076] The back of the vertical section of the L-shaped bone 31 abuts against the main body of the hanging bracket 21.

[0077] Specifically, such as Figure 3 As shown, the secondary keel 3, through the L-shaped cross-section of the L-shaped keel 31, forms a cooperative force-bearing system with the screw hanger 1 and the hanger 2. The horizontal section of the L-shaped keel 31 is detachably connected to the bottom end of the screw hanger 1 through the third connecting through hole 3a, so that the vertical load of the screw hanger 1 is transferred to the horizontal section of the L-shaped keel 31; the back of the vertical section of the L-shaped keel 31 is in close contact with the hanger body 21, transferring the load to the main keel 4 through the hanger 2. Specifically, after the bottom end of the screw hanger 1 passes through the third connecting through hole 3a, it is fixed by a nut or buckle, forming a vertical tensile constraint; the vertical section of the L-shaped keel 31 serves as a force-bearing fulcrum, and its back is in contact with the hanger body 21, resisting the horizontal shear force through friction and the limiting structure. The main keel 4 is laterally positioned through the limiting port 23 of the hanging bracket 2, while the L-shaped section of the L-shaped bone 31 converts the vertical load of the screw hanger 1 into a lateral supporting force on the main keel 4, forming a mechanical transmission path of "screw hanger 1 → L-shaped bone 31 → hanging bracket 2 → main keel 4".

[0078] To further explain, the secondary keel 3 also includes an L-shaped bone bar 32;

[0079] The vertical section of the L-shaped bone 31 is provided with a fourth connecting through hole 3b, and the two ends of the vertical section of the L-shaped bone barcode 32 are symmetrically provided with fifth connecting through holes 3c. The fourth connecting through hole 3b and the fifth connecting through hole 3c are provided in a one-to-one correspondence. The connector 5 is installed through the fourth connecting through hole 3b and the fifth connecting through hole 3c.

[0080] The horizontal section of the L-shaped bone brace 32 is symmetrically provided with a sixth connecting through hole 3d at both ends. The sixth connecting through hole 3d and the third connecting through hole 3a are provided in a one-to-one correspondence. The connector 5 is installed through both the sixth connecting through hole and the third connecting through hole 3a.

[0081] Specifically, such as Figure 4As shown, the L-shaped keel bracket 32 ​​achieves modular extension and mechanical performance enhancement of the secondary keel 3 through multi-directional connecting through holes. When it is necessary to extend the secondary keel 3, the two ends of the vertical section of the L-shaped keel bracket 32 ​​are respectively attached to the vertical section of the original L-shaped keel 31, so that the fifth connecting through hole 3c of the L-shaped keel bracket 32 ​​is aligned with the fourth connecting through hole 3b of the original L-shaped keel 31, and fixed through by high-strength bolts and other connecting parts 5, forming a rigid connection in the vertical direction; at the same time, the two ends of the horizontal section of the L-shaped keel bracket 32 ​​are connected to the third connecting through hole 3a of the adjacent L-shaped keel 31 through the sixth connecting through hole 3d, and the connecting parts 5 are used to achieve lateral reinforcement. The load transfer path is as follows: the vertical tension of the screw rod 1 is transferred to the horizontal section of the L-shaped keel 31 through the third connecting through hole 3a, then to the fifth through hole connection node of the L-shaped keel bracket 32 ​​through the vertical section of the L-shaped keel 31, and then distributed to the adjacent keel unit through the sixth connecting through hole 3d of the horizontal section of the L-shaped keel bracket 32. The L-shaped bone barb 32 features a bidirectional through-hole design, which enables it to have both longitudinal extension and lateral constraint functions, significantly improving the overall stiffness of the connection area.

[0082] Further explanation also includes the Z-shaped key 6;

[0083] The top horizontal section of the Z-shaped bracket 6 is bent to form a bracket slot 61 that matches the secondary keel 3. The vertical section of the Z-shaped bracket 6 is fitted and installed in close contact with the vertical section of the L-shaped keel 31. The bottom horizontal section of the Z-shaped bracket 6 and the horizontal section of the L-shaped keel 31 are located on the same horizontal plane. The bottom horizontal section of the Z-shaped bracket 6 and the horizontal section of the L-shaped keel 31 are used to jointly support the board to be installed.

[0084] Specifically, such as Figure 7 As shown, the Z-shaped bracket 6 achieves coordinated load-bearing between the secondary keel 3 and the board through a three-dimensional support structure. The bracket slot 61 formed by the bending of its top horizontal section fits against the back of the vertical section of the secondary keel 3, forming a lateral constraint through friction and the limiting structure. The vertical section of the Z-shaped bracket 6 is fixed to the vertical section of the L-shaped keel 31 with bolts or welding, forming an I-shaped combined section that shares the load. The bottom horizontal section is coplanar with the horizontal section of the L-shaped keel 31, forming the direct support surface for the board. The load transfer path is as follows: the weight of the board is transferred through the coplanar horizontal section to the combined structure of the L-shaped keel 31 and the Z-shaped bracket 6, then through the vertical section to the hanging bracket 2 and the main keel 4, and finally distributed to the main building structure by the screw hanger 1.

[0085] A ceiling, employing a ceiling suspension structure as described above;

[0086] The bottom horizontal section of the Z-shaped support 6 and the horizontal section of the L-shaped bone 31 are used together to support the fireproof rock wool 7;

[0087] The main keel 4 is equipped with a high-strength fiberglass cloth all-purpose board 8, fireproof rock wool 7 and lily board 9 from top to bottom through connectors 5. The high-strength fiberglass cloth all-purpose board 8 and fireproof rock wool 7 are not attached to each other to form a fireproof space 10, while the fireproof rock wool 7 and lily board 9 are attached to each other.

[0088] Specifically, this ceiling achieves both high-efficiency fire resistance and structural stability through the synergistic configuration of a modular suspension structure and multiple layers of fire-resistant materials.

[0089] like Figure 8-10 As shown, firstly, the secondary keel 3 is suspended from the top of the building by screw hangers 1, forming a longitudinal load-bearing frame; secondly, the hangers 2 vertically connect the secondary keel 3 and the main keel 4, forming a grid-like support system. Finally, fireproof rock wool 7 is filled between the high-strength fiberglass cloth all-purpose board 8 and the lily board 9 to form a fireproof isolation zone: the bottom horizontal section of the bracket and the horizontal section of the L-shaped bone 31 jointly support the fireproof rock wool 7, and its bracket slot 61 and the vertical section of the L-shaped bone 31 form a lateral limit to prevent the rock wool from shifting; the high-strength fiberglass cloth all-purpose board 8 is connected to the main keel 4 through connectors 5, and is not directly attached to the fireproof rock wool 7, leaving a fireproof space 10 to block the heat conduction path; the lily board 9 is directly laid on the surface of the fireproof rock wool 7, using its lightweight and high-strength characteristics to distribute the load.

[0090] In summary, this ceiling, through the synergistic innovation of fire-resistant space 10 structure and mechanical properties, achieves lightweight and rapid construction while meeting the highest fire resistance requirements. It solves the core pain points of traditional ceilings, such as structural overload and complex construction caused by the integration of fire-resistant and decorative layers, and is especially suitable for high-rise buildings, underground spaces and other scenarios with stringent requirements for fire resistance and space efficiency.

[0091] To further explain, a fireproof sealant layer 11 is provided at the connection between the high-strength fiberglass cloth all-purpose board 8 and the I-shaped frame 41.

[0092] like Figure 8-10 As shown, due to the assembly gap at the connection between the high-strength fiberglass cloth all-purpose board 8 and the I-shaped frame 41, the fireproof sealant layer 11 fills the gap and cures to form a continuous flame-retardant barrier, thereby improving the fire resistance limit.

[0093] To further explain, the number of lily boards 9 is 3 layers. The bottom layer of lily board 9 is equipped with a flat strip 12. The connector 5 is sequentially inserted through the flat strip 12 and each layer of lily board 9, and the fireproof sealant layer 11 is provided at the connection between the connector 5 and the flat strip 12.

[0094] Furthermore, such as Figure 8-10As shown, this ceiling suspension structure achieves balanced load transfer and enhanced fire resistance through the composite configuration of multiple layers of lily boards 9 and the synergistic reinforcement of flat strips 12. The three layers of lily boards 9 are installed in an overlapping manner, with the flat strips 12 fixedly installed on the back of the bottom layer of lily boards 9. The flat strips 12 are then fixed to the upper layer of lily boards 9 by the connectors 5 penetrating the flat strips 12. A fire-retardant sealant layer 11 is filled at the threaded engagement between the flat strips 12 and the connectors 5, and forms a flame-retardant sealing layer after curing. The flat strips 12, through their lateral extension structure, disperse the local pressure of the connectors 5 on the lily boards 9, while the fire-retardant sealant layer 11 both prevents flames from spreading along the connectors 5 and compensates for the small gaps between the flat strips 12 and the connectors 5, preventing heat radiation conduction.
