Description

Technical Field

[0001] The present invention relates to the field of building decoration, and particularly to an assembled double-axis snap spring integrated ceiling structure. Background Art

[0002] Currently, the mainstream metal integrated ceiling panels are mainly hook-and-latch structure panels made of aluminum gusset plates and aluminum single plates. Their main advantages are light weight and convenient installation. Their disadvantages are as follows: 1. The plate width is limited and cannot be made very large. 2. The middle part of the plate will sink under the influence of gravity, affecting the appearance. 3. The metal ceiling panels are fixed by the protrusions on the side with friction. After long-term use, they are easily loosened or even dropped under the influence of the room air flow. 4. It is very difficult to make the interfaces neat and uniform after installation, affecting the appearance; if the flatness of the metal aluminum plate surface is to be high, it is necessary to increase the thickness of the aluminum plate, and at the same time, the aluminum consumption will increase accordingly. Is there an assembled metal plate integrated ceiling structure that should be simple to assemble, and each piece can be disassembled and assembled separately, with convenient disassembly and assembly, and it is guaranteed to be difficult to fall off during long-term use. Under the condition of ensuring neat and uniform joints, there are also various treatment schemes for the seams. That would be a very meaningful ceiling solution. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an assembled double-axis snap spring integrated ceiling structure with simple construction process, reliable quality and good environmental protection.

[0004] To solve the above problems, the present invention is realized through the following technical solutions: An assembled double-axis snap spring integrated ceiling structure includes a top keel, a double-spring snap spring mechanism and a top plate. The top keel is arranged vertically and horizontally to form a keel framework. The double-spring snap spring mechanism is fixed to the outer edge of the top surface of the top plate. The top keel is a hollow "I"-shaped keel, including a top keel protrusion, a top keel recess and a bottom keel protrusion; the double-spring snap spring mechanism includes a fixed seat, a deflection column and a spring piece. The fixed seat is fixedly connected to the top plate. The lower end of the deflection column is pin-connected to the fixed seat through a column pin. A column torsion spring is sleeved on the column pin, and the column torsion spring elastically acts on the deflection column. The upper end of the deflection column is pin-connected to the spring piece through a spring piece pin. A spring piece torsion spring is sleeved on the spring piece pin, and the spring piece torsion spring elastically acts on the spring piece. The front end of the spring piece extends into the top keel recess to realize the hanging installation of the top plate on the top keel.

[0005] Fixing of the top keel to the building top surface: A hoisting frame is provided on the top keel. The hoisting frame is externally clamped to the top keel protrusion and the top keel recess, and the hoisting frame is fixedly connected to the top keel through hoisting frame fixing screws. A lead screw is provided at the top of the hoisting frame. The lower end of the lead screw is fixedly connected to the hoisting frame, and the upper end of the lead screw is fixedly connected to the building top surface.

[0006] Fixing of the fixing base on the top plate: The fixing base includes a fixing base bottom surface that fits against the top surface of the top plate, a fixing base back plate that is perpendicularly arranged with respect to the fixing base bottom surface, and fixing base side plates located on both sides of the fixing base back plate. The fixing base bottom surface is fixed to the top surface of the top plate by fixing base screws.

[0007] Rotational connection between the deflection column and the fixing base: The deflection column includes a column back plate and column side plates on both sides. The column side plates are arranged outside the fixing base side plates. A column pin penetrates through the column side plates and the fixing base side plates. The fixing base back plate and the column back plate are arranged facing away from each other. One end of the column torsion spring abuts against the fixing base back plate, and the other end hooks on the lower edge of the column back plate and follows the deflection column. When the column torsion spring is in the reset state, the deflection column remains in a vertically upright state.

[0008] Rotational connection between the elastic piece and the deflection column: The elastic piece includes an elastic piece back plate and elastic piece side plates on both sides. The column side plates are arranged outside the elastic piece side plates. An elastic piece pin penetrates through the column side plates and the elastic piece side plates. The elastic piece back plate and the column back plate are arranged facing away from each other. One end of the elastic piece torsion spring abuts against the column back plate, and the other end is fixed to the elastic piece side plate and follows the elastic piece. When the elastic piece torsion spring is in the reset state, the elastic piece side plates are in an outwardly expanded state. The front end of the elastic piece side plates protrudes beyond the side of the column side plates of the deflection column, and the elastic piece back plate also exposes the side of the column side plates and is in an inclined state.

[0009] When the top plate is hung on the top keel, the deflection column is inserted between two adjacent parallel top keels in the same direction. During the continuous upward pushing of the top plate, the deflection column enters between the protrusions under the two top keels. Subsequently, the elastic piece back plate on the elastic piece installed at the upper end of the deflection column will first touch the lower edge of the protrusion under the top keel. Since the elastic piece back plate is in an inclined state, the upward thrust on the top plate decomposes into an inward squeezing force on the elastic piece back plate. Since the elastic piece and the deflection column are rigidly connected, the inward squeezing force will be transmitted to the deflection column. After overcoming the reaction force generated by the column torsion spring, the deflection column can deflect inward with the column pin as the axis. As the top plate is pushed upward, the elastic piece back plate will climb along the protrusion under the top keel. The inclined elastic piece back plate guides the front end protrusion of the elastic piece side plates into the inside of the protrusion under the top keel. As it is further pushed upward, the front end protrusion of the elastic piece side plates is also guided into the protrusion under the top keel and finally reaches the concave of the top keel. At this time, the front end protrusion of the elastic piece side plates loses the horizontal limit of the protrusion under the top keel. Under the reaction force generated by the torsion spring, the deflection column can return to the vertical initial state again, and the front end protrusion of the elastic piece side plates enters the concave of the top keel, thus completing the hanging of the top plate on the top keel framework.

[0010] When the top plate is removed from the top keel, a downward pulling force is applied to the top plate. Due to the rigid connection of each component, the pulling force is ultimately transmitted to the elastic piece. The elastic piece is pin-connected to the deflection column through the elastic piece pin. After overcoming the reaction force of the elastic piece torsion spring, as the top plate moves downward, the elastic piece rotates around the elastic piece pin. Eventually, the edge of the elastic piece side plate turns to the outside, fits against the inner wall of the protrusion under the top keel, and finally detaches from the top keel. The elastic piece resets under the action of the elastic piece torsion spring, completing the removal of the top plate from the top keel.

[0011] To facilitate the hanging and docking of the top plate with the top keel, further: a column guide fillet is provided at the upper end of the column side plate. By using the column guide fillet, alignment can be guided during the hanging of the top plate. Additionally, a hanging part of the elastic piece is formed at the front end of the elastic piece side plate. The hanging part of the elastic piece includes a front elastic piece guide fillet and a hanging and fitting surface. The elastic piece guide fillet, when the top plate is installed, the hanging part of the elastic piece will contact the protrusion under the top keel. A elastic piece guide fillet is provided at this contact point, reducing the frictional resistance with the protrusion under the top keel. At the same time, the hanging part of the elastic piece can smoothly transition from the protrusion under the top keel into the concave of the top keel. The hanging and fitting flat surface, after the elastic piece completely enters the concave of the top keel to complete the hanging, the hanging and fitting flat surface fits against the side wall of the concave of the top keel, making the hanging more stable.

[0012] To achieve diversification in the splicing of the top plates, further: the side walls of adjacent top plates can be in contact to form a closely spliced joint of the top plates, or there can be a gap between the side walls of the top plates to form a joint with a gap between the top plates. The gap control between the top plates is achieved by adjusting the installation position of the double spring clip mechanism on the top plates. For the joint with a gap, a T-shaped separator can also be provided at the gap, and the T-shaped separator is fixed to the bottom surface of the protrusion under the top keel.

[0013] To strengthen the hanging stability of the top plate on the top keel, further: a shock-absorbing and limiting strip is provided between the top keel and the top plate. By using the shock-absorbing and limiting strip, the distance between the top plate and the top keel can be adjusted. Adjusting the thickness of the shock-absorbing and limiting strip can adjust the distance between the top plate and the top keel, thereby also achieving the adjustment of the hanging tightness of the elastic piece on the top keel. The shock-absorbing and limiting strip is made of rubber material, improving the sound insulation effect of the overall structure.

[0014] The structure of the top plate can also be diversified, specifically as follows:

[0015] Top plate structure one: The top plate is composed of a metal panel and a filling gypsum board wrapped inside the metal panel. The metal panel is turned inward to form a panel connection part, and the fixing seat is fixed to the panel connection part.

[0016] Top plate structure two: The top plate is composed of an aluminum honeycomb panel and a metal connecting piece fixedly arranged on the outer edge of the aluminum honeycomb panel. The fixing seat is fixed to the metal connecting piece.

[0017] To ensure the reliability of the ceiling board hanging installation, further: The double-spring snap ring mechanism is provided with at least two on each of the two sides of the ceiling board. Whether the edge of the ceiling board is lengthened or the self-weight of the ceiling board is increased, the installation quantity on the ceiling board can be increased according to actual needs.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The entire ceiling structure is completely produced and installed by an assembled process. The supporting high-load light steel keel ensures the strength of the ceiling layer. The high-load light steel keel framework meets the requirements for maintenance and access by personnel. The unique hoisting component can make each ceiling board fixed more tightly and is difficult to fall off, and each board can be disassembled separately, making the later maintenance more convenient. The entire installation process fully meets the requirements of the assembled integrated ceiling structure. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figure 1 shown, an assembled double-axis clip integrated ceiling structure includes a ceiling joist 1, a double spring clip mechanism 2 and a top plate 3. The double spring clip mechanism 2 is fixedly connected to the top plate 3, and the double spring clip mechanism 2 is hung on the ceiling joist 1. At least one double spring clip mechanism 2 is provided on each side of the top plate 3, and a shock-absorbing and limiting strip 7 is provided between the ceiling joist 1 and the top plate 3.

[0035] As Figure 7 shown, the ceiling joist 1 is a hollow "I"-shaped joist, including a protrusion 1-1 on the ceiling joist, a concave 1-2 on the ceiling joist, and a protrusion 1-3 under the ceiling joist, which is an integral structure formed by cold bending of galvanized steel sheet. The bite point 1-4 is located on the top surface of the protrusion 1-1 on the ceiling joist. The bite point 1-4 improves the structural strength of the protrusion 1-1 on the ceiling joist due to the increased local wall thickness of the protrusion 1-1 on the ceiling joist; a shallow inner groove 1-5 is provided on the top surface of the protrusion 1-3 under the ceiling joist. Similarly, by using the shallow inner groove 1-5 to form an uneven structure on the lower plane of the protrusion 1-3 under the ceiling joist, the structural strength of the protrusion 1-3 under the ceiling joist is also enhanced. The shallow inner groove 1-5 can also be used as a positioning groove for the shock-absorbing and limiting strip 7 to assist in positioning the shock-absorbing and limiting strip 7.

[0036] As Figure 8 shown, a hoisting frame 9 is provided on the top keel 1. The hoisting frame 9 is externally clamped on the protrusion 1-1 and the concave 1-2 of the top keel, and the hoisting frame 9 is fixedly connected to the top keel 1 through hoisting frame fixing screws 8. A lead screw 10 is provided at the top of the hoisting frame 9. The lower end of the lead screw 10 is fixedly connected to the hoisting frame 9, and the upper end of the lead screw 10 is fixedly connected to the building top surface;

[0037] As Figure 4 and ​ shown, the outer layer of the top plate 3 is a metal panel 3-1. The metal panel 3-1 can be a metal type plate such as a stainless steel plate, an electrolytic steel plate, an aluminum plate, or a galvanized plate. The thickness of the plate is generally between 0.4 mm and 1.2 mm. The four sides of the metal plate 3-1 are bent to form a panel connection part 3-1-1 on the top surface for fixing the double spring clip mechanism 2. The back is pasted with an inorganic filler such as a filling gypsum board 3-2 or a corrugated aluminum plate. As ​ shown, the inorganic filler can also be replaced by setting reinforcing ribs. As ​ and ​ shown, the structure of the top plate 3 can also be composed of an aluminum honeycomb panel 3-3 and a metal connector 3-4 fixedly arranged on the outer edge of the aluminum honeycomb panel 3-3, which is an all-aluminum structure. The fixing seat 2-1 is fixed on the connector 3-4. The aluminum honeycomb panel 3-3 adopts a structure with the edge turned up, which increases the edge thickness of the top plate 3 and improves the structural strength of the top plate 3. The folding process of the aluminum honeycomb panel 3-3 is as ​ shown. For the two structures of the top plate 3, the former is more economical and practical, and the latter all-aluminum structure is more lightweight, and can be selected according to actual needs.

[0038] As ​ and ​ shown, the double spring clip mechanism 2 includes a fixing seat 2-1, a deflecting column 2-2 and a spring piece 2-3. The fixing seat 2-1 is fixedly connected to the top plate 3. The lower end of the deflecting column 2-2 is pin-connected to the fixing seat 2-1 through a column pin 2-4. A column torsion spring 2-5 is sleeved on the column pin 2-4. The column torsion spring 2-5 elastically acts on the deflecting column 2-2. The upper end of the deflecting column 2-2 is pin-connected to the spring piece 2-3 through a spring piece pin 2-6. A spring piece torsion spring 2-7 is sleeved on the spring piece pin 2-6. The spring piece torsion spring 2-7 elastically acts on the spring piece 2-3. The front end of the spring piece 2-3 extends into the concave 1-2 of the top keel to realize the hanging installation of the top plate 3 on the top keel 1.

[0039] The fixed seat 2-1 includes a fixed seat bottom surface 2-1-1 that fits against the top surface of the top plate 3, a fixed seat back plate 2-1-2 that is perpendicular to the fixed seat bottom surface 2-1-1, and fixed seat side plates 2-1-3 on both sides of the fixed seat back plate 2-1-2. The fixed seat bottom surface 2-1-1 is fixed to the top surface of the top plate 3 by a fixed seat screw 4. The deflection column 2-2 includes a column back plate 2-2-1 and column side plates 2-2-2 on both sides. The column side plates 2-2-2 are arranged on the outside of the fixed seat side plates 2-1-3. A column pin 2-4 passes through the column side plates 2-2-2 and the fixed seat side plates 2-1-3. The fixed seat back plate 2-1-2 and the column back plate 2-2-1 are arranged facing away from each other. One end of a column torsion spring 2-5 abuts against the fixed seat back plate 2-1-2, and the other end is hooked on the lower edge of the column back plate 2-2-1 and follows the deflection column 2-2. The elastic sheet 2-3 includes an elastic sheet back plate 2-3-1 and elastic sheet side plates 2-3-2 on both sides. The column side plates 2-2-2 are arranged on the outside of the elastic sheet side plates 2-3-2. An elastic sheet pin 2-6 passes through the column side plates 2-2-2 and the elastic sheet side plates 2-3-2. The elastic sheet back plate 2-3-1 and the column back plate 2-2-1 are arranged facing away from each other. One end of an elastic sheet torsion spring 2-7 abuts against the column back plate 2-2-1, and the other end is fixed to the elastic sheet side plates 2-3-2 and follows the elastic sheet 2-3.

[0040] Such as ​As shown, when the top plate 3 is hung on the top keel 1, the deflecting column 2-2 is inserted between two adjacent parallel top keels 1 in the same direction. At the upper end of the column side plate 2-2-2, there is a column guiding fillet 2-2-2-1, which is convenient for alignment and guiding during insertion. During the continuous upward pushing of the top plate 3, the deflecting column 2-2 enters between the lower protrusions 1-3 of the two top keels. Subsequently, the back plate 2-3-1 of the elastic piece 2-3 installed at the upper end of the deflecting column 2-2 will first touch the lower edge of the lower protrusion 1-3 of the top keel. Since the back plate 2-3-1 of the elastic piece is in an inclined state, the upward thrust on the top plate 3 decomposes into an inward squeezing force on the back plate 2-3-1 of the elastic piece. Since the elastic piece 2-3 and the deflecting column 2-2 are rigidly connected, the inward squeezing force will be transmitted to the deflecting column 2-2. After overcoming the reaction force generated by the column torsion spring 2-5, the deflecting column 2-2 can deflect inward with the column pin 2-4 as the axis. As the top plate 3 is pushed upward, the back plate 2-3-1 of the elastic piece will climb along the lower protrusion 1-3 of the top keel. The inclined back plate 2-3-1 of the elastic piece will also cause the front end of the elastic piece side plate 2-3-2 to form a protruding elastic piece hanging part 2-3-2-1 to enter the inner side of the lower protrusion 1-3 of the top keel. As it is pushed upward further, the elastic piece hanging part 2-3-2-1 is smoothly guided into the lower protrusion 1-3 of the top keel under the guidance of the front elastic piece guiding fillet 2-3-2-1-1 and finally reaches the inner concave 1-2 of the top keel. At this time, the elastic piece hanging part 2-3-2-1 loses the horizontal limit of the lower protrusion 1-3 of the top keel. Under the reaction force generated by the column torsion spring 2-5, the deflecting column 2-2 can return to the vertical initial state again, and the elastic piece hanging part 2-3-2-1 enters the inner concave 1-2 of the top keel, and the hanging and fitting plane 2-3-2-1-2 fits the side wall of the inner concave 1-2 of the top keel, thus completing the hanging of the top plate 3 on the top keel frame.

[0041] As ​ shown, when the top plate 3 is removed from the top keel 1, the glass suction cup is adsorbed on the top plate 3, and a downward pulling force is applied to the top plate 3. Due to the rigid connection of each component, the pulling force is finally transmitted to the elastic piece 2-3. The elastic piece 2-3 is pin-connected to the deflecting column 2-2 through the elastic piece pin 2-6. After overcoming the reaction force of the elastic piece torsion spring 2-7, as the top plate 3 moves downward, the elastic piece 2-3 rotates with the elastic piece pin 2-6 as the axis. Finally, the edge of the elastic piece side plate 2-3-2 turns to the outside, fits the inner wall of the lower protrusion 1-3 of the top keel and finally detaches from the top keel 1. The elastic piece 2-3 is reset under the action of the elastic piece torsion spring 2-7, completing the removal of the top plate 3 from the top keel 1.

[0042] Two top plate splicing methods of close splicing and leaving a gap are adopted: The side walls between adjacent top plates 3 are attached to form close splicing of the top plates 3, as ​ shown. It is also possible to leave a gap 5 between the side walls of the top plates 3 to form leaving-a-gap splicing of the top plates 3 as ​ and​ As shown, a T-shaped partition strip 6 is provided at the gap 5, and the T-shaped partition strip 6 is fixed to the bottom surface of the protrusion 1-3 under the top keel.

[0043] During installation, according to the drawing, assemble the top keel 1 into a top keel frame composed of rectangular grids one by one, and take fixing measures such as diagonal braces. After the top keel 1 is fixed, people can start construction. Install the roof panel 3. Connect the double spring clip mechanism 2 through the fixing seat screws 4 and fix it around the metal structure roof panel 3. The fixing spacing depends on the size of the board. The conventional size is 1200mm×600mm. Fix two on each side of the 1200mm side. After fixing, align the roof panel 3 with the rectangular frame of the top keel 1 and push it upwards. The rectangular frame is smaller than the outer diameter of the roof panel 3. Under some conditions with low requirements, the top keel 1 can also be replaced by a square tube keel instead of an I-beam keel.

[0044] It should be emphasized that: the above are only the preferred embodiments of the present invention, and there is no any form of limitation to the present invention. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
