Description

Technical Field

[0001] This invention relates to a fixing structure and installation method for an integrated bathroom ceiling panel, and pertains to the field of construction. Background Technology

[0002] Currently, traditional bathroom ceilings mostly use integrated aluminum composite panel ceilings. These ceilings consist of two parts: a base layer and a surface layer. The base layer includes an aluminum alloy main keel, which is fixedly installed on the top frame of the bathroom structure. The spacing can be determined according to the apartment's dimensions. The surface layer includes aluminum composite panel edging panels and aluminum composite panel surface panels. The ceiling is directly hung from the original bathroom ceiling and walls using hangers. This method is highly industrialized, but the hangers must be installed first, followed by the keel. However, this method has limitations due to the complex piping and wiring in bathroom ceilings, restricting the placement of the hangers and potentially damaging the waterproofing layer of the bathroom ceiling. Therefore, hanger-less ceilings are increasingly common, using an overlapping method to directly install the ceiling panels onto the wall panels via the keel.

[0003] This overlapping method solves the problem of traditional hanging rod ceiling structures. However, because the ceiling panels are directly overlapped, when the ceiling panels are lightweight and the bathroom space is small, the negative pressure generated in the bathroom space when the door is opened will cause the entire ceiling panel to lift up, creating a certain safety hazard. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a ceiling panel fixing structure and installation method that can resist the negative pressure on the ceiling panel when the door of a small bathroom is opened quickly.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fixing structure for an integrated bathroom ceiling panel, including a Z-shaped keel connected to the top of the ceiling panel, with both ends of the Z-shaped keel protruding outwards from both ends of the ceiling panel to form overlapping ends, a wall-top connecting member connected to the wall panel, the overlapping ends of the Z-shaped keel resting on the wall-top connecting member, and a reinforcing rotating angle bracket installed on the overlapping ends, the reinforcing rotating angle bracket connecting the Z-shaped keel and the wall.

[0006] Furthermore, the reinforced rotating bracket includes a first connecting part and a second connecting part distributed at right angles. The first connecting part is rotatably installed on the overlapping end before the zigzag keel is placed on the top wall connecting member. The second connecting part is attached to the wall and secured to the wall after the zigzag keel is placed on the top wall connecting member.

[0007] Furthermore, the overlapping end is provided with mounting holes. The first connecting part of the reinforcing rotating angle bracket is attached to the Z-shaped keel. The reinforcing rotating angle bracket is fixed by bolts passing through the mounting holes of the first connecting part and the overlapping end, and is installed at the end of the bolts with nuts. At the same time, the first connecting part is rotated around the bolt as an axis.

[0008] Furthermore, the second connecting part of the reinforced rotating bracket is connected to the wall by two screws.

[0009] Furthermore, the reinforcing rotating bracket is formed by bending a square strip at a 90-degree angle, which forms a first connecting part and a second connecting part. The first connecting part has corresponding holes for bolts to pass through, and the second connecting part has two holes for screws to pass through.

[0010] Furthermore, the zigzag keel, as a component to prevent deformation of the ceiling panel and connect the wall and ceiling, has at least two on each ceiling panel. The two zigzag keels are parallel to each other and spaced apart. The zigzag keels are connected to the ceiling panel with screws. At the same time, there are reinforcement components between the zigzag keels and the ceiling panel. There are multiple reinforcement components, which are distributed at intervals along the zigzag keels. The reinforcement components include a horizontal main body, with limiting parts on both sides above the horizontal main body. The limiting parts are connected to the horizontal main body, and a sliding groove is formed between the limiting parts and the horizontal main body. The bottom sides of the zigzag keel have horizontally outwardly extending outer edges. The reinforcement components are locked onto the two outer edges of the zigzag keel by the two limiting parts and can slide to the appropriate position through the sliding groove. Finally, the zigzag keel, reinforcement components, and ceiling panel are connected by screws.

[0011] Furthermore, the wall-top connecting component includes a U-shaped snap-fit ​​part, which is inverted and fastened to the top of the wall panel, so that the wall-top connecting component can be firmly fixed to the wall panel. The end of the snap-fit ​​part near the outer side of the wall panel extends horizontally to the outer side of the wall panel, then vertically, and then horizontally again to form a second step surface and a third step surface. The top of the snap-fit ​​part is the first step surface, which is used to support the Z-shaped keel. The bottom of the second step surface is a concave shape, and the third step surface is used to support the ceiling panel.

[0012] The installation method for the fixed structure of the integrated bathroom ceiling panel includes the following steps:

[0013] Step 1: Secure the top wall connector to the wall panel;

[0014] Step 2: Assemble the zigzag keel with the ceiling panel, insert bolts at both ends of the ceiling panel, install reinforcing rotating brackets on the bolts, and then install nuts to limit the reinforcing rotating brackets. Before installing the ceiling panel, the second connection part of the reinforcing rotating bracket should face upwards to avoid interfering with the lifting and installation of the ceiling panel.

[0015] Step 3: Raise the ceiling panel to the top and overlap the two ends of the zigzag joists onto the connecting components at the top of the wall;

[0016] Step 4: Rotate the reinforcement rotary angle code so that the second connecting part is attached to the wall, tighten the nut to limit the reinforcement rotary angle code, and finally fasten the second connecting part to the wall with screws.

[0017] Advantages of the present invention:

[0018] In the present invention, a grooved keel is installed on the top of the ceiling board to prevent the ceiling board from deforming. The two ends of the grooved keel are lapped on the top of the wall board, and a reinforcement rotary angle code is installed on the lapping ends of the two ends of the grooved keel. The reinforcement rotary angle code includes a first connecting part and a second connecting part distributed at a right angle. The first connecting part is rotatably installed on the lapping end before the grooved keel is lapped on the wall top connecting member. Since the size of the lower opening of the overall frame formed by enclosing the wall top connecting members is smaller than the area of the ceiling surface after all the ceiling boards are spliced, only in this way can the ceiling board and the grooved keel be lapped on the overall frame. The purpose of the rotatable design of the first connecting part is to rotate the first connecting part of the reinforcement rotary angle code before lifting so that the second connecting part is arranged upward, thereby avoiding interference of the reinforcement rotary angle code on the lifting and installation of the ceiling board; after the grooved keel is lapped on the wall top connecting member, the second connecting part is made to be in contact with and fastened to the wall by rotating the first connecting part, thereby fixing the ceiling board. After the ceiling board is effectively fixed by the reinforcement rotary angle code, it can resist the negative pressure on the ceiling board when the door of the small-space integral bathroom is quickly opened.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only some, not all, of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0030] Reference Figure 1 , Figure 2 , Figure 4 , Figure 1 This is a three-dimensional schematic diagram of the overall structure of the present invention. Figure 2 This is a partially enlarged view of the overall structure of the present invention. Figure 4 The invention provides a schematic diagram of the overall structure. A fixed structure for an integrated bathroom ceiling panel is used to fix the ceiling panel 2 to the wall to prevent it from shifting upwards. The fixed structure includes a U-shaped keel 3 connected to the top of the ceiling panel 2. Both ends of the U-shaped keel 3 protrude outwards from both ends of the ceiling panel 2 to form overlapping ends 31. A wall-top connecting member 5 is connected to the wall panel 1. The overlapping ends 31 of the U-shaped keel 3 rest on the wall-top connecting member 5. A reinforcing rotating bracket 4 is installed on the overlapping ends 31. The reinforcing rotating bracket 4 connects the U-shaped keel 3 to the wall, fixing the U-shaped keel 3 and providing resistance to negative pressure lifting.

[0031] As a preferred embodiment, refer to Figure 2 , Figure 3 , Figure 2 This is a partially enlarged view of the overall structure of the present invention. Figure 3This is a schematic diagram of the assembly structure of the reinforced rotating angle bracket and the zigzag keel of the present invention. The reinforced rotating angle bracket 4 includes a first connecting part 41 and a second connecting part 42 distributed at right angles. The first connecting part 41 is rotatably installed on the overlapping end 31 before the zigzag keel 3 overlaps the wall-top connecting member 5. Since the size of the lower opening of the overall frame formed by the wall-top connecting member 5 is smaller than the size of the ceiling surface area after all the ceiling panels 2 are spliced, this allows the ceiling panels 2 and the zigzag keel 3 to overlap on the overall frame. The first connecting part 41 is rotatable. The design purpose is that the ceiling panel 2 needs to be lifted diagonally to the top of the overall frame before being laid down horizontally. Before lifting, the first connecting part 41 of the reinforcing rotating bracket 4 can be rotated so that the second connecting part 42 faces upward, thereby avoiding interference from the reinforcing rotating bracket 4 in the lifting and installation of the ceiling panel 2. After the Z-shaped keel 3 is placed on the wall top connecting component 5, the second connecting part 42 is made to fit against the wall and be firmly fixed to the wall by rotating the first connecting part 41, thereby fixing the ceiling panel 2 and preventing negative pressure lifting.

[0032] As a preferred embodiment, refer to Figure 3 , Figure 3 This is a schematic diagram of the assembly structure of the reinforced rotating angle bracket and the zigzag keel of the present invention. The overlapping end 31 is provided with mounting holes. The first connecting part 41 of the reinforced rotating angle bracket 4 is attached to the zigzag keel 3. The reinforced rotating angle bracket 4 is fixed by bolts 6 passing through the mounting holes of the first connecting part 41 and the overlapping end 31, and is installed at the end of the bolts 6 with nuts 61. This fixes the first connecting part 41 and allows it to rotate about the bolts 6 as an axis. The method of connecting the reinforced rotating angle bracket 4 and the zigzag keel 3 with bolts 6 not only serves a connecting function, but also allows the bolts 6 to act as the rotation axis of the first connecting part 41, simplifying the structure and making installation more convenient.

[0033] As a preferred implementation method, refer to Figure 2 , Figure 2 This is a partial enlarged view of the overall structure of the present invention; the second connecting part 42 of the reinforcing rotating angle bracket 4 is connected to the wall by two screws. The method of fixing the reinforcing rotating angle bracket 4 to the wall with screws is the simplest and makes the installation more convenient.

[0034] As a preferred embodiment, refer to Figure 3 , Figure 3This is a schematic diagram of the assembly structure of the reinforced rotating angle bracket and the Z-shaped keel of the present invention. The reinforced rotating angle bracket 4 is formed by bending a square strip at a 90-degree angle, which forms a first connecting part 41 and a second connecting part 42. The first connecting part 41 has a hole for the bolt 6 to pass through, and the second connecting part 42 has two holes for the screw to pass through. Alternatively, the second connecting part 42 may not have holes. The screw connecting the second connecting part 42 and the wall can be a self-tapping screw. The reinforced rotating angle bracket 4 can be made of aluminum alloy, which makes it easier to screw in the self-tapping screw.

[0035] The installation method for the fixed structure of the integrated bathroom ceiling panel includes the following steps:

[0036] Step 1: Secure the top wall connecting component 5 to the wall panel 1;

[0037] Step 2: Assemble the Z-shaped keel 3 with the ceiling panel 2, insert bolts 6 at both ends of the ceiling panel 2, install the reinforcing rotating bracket 4 on the bolts 6, and then install the nut 61 to limit the reinforcing rotating bracket 4. Before installing the ceiling panel 2, the second connecting part 42 of the reinforcing rotating bracket 4 is set upward so as not to interfere with the lifting and installation of the ceiling panel 2.

[0038] Step 3: Raise the ceiling panel 2 to the top and overlap both ends of the Z-shaped keel 3 onto the wall top connecting component 5;

[0039] Step 4: Rotate the reinforcing rotating bracket 4 so that the second connecting part 42 is attached to the wall, tighten the nut 61 to limit the reinforcing rotating bracket 4, and finally use screws to fasten the second connecting part 42 to the wall.

At least two Z-shaped keels 3 are provided on each ceiling panel 2, with the two keels parallel to each other and spaced apart. The Z-shaped keels 3 are connected to the ceiling panel 2 by screws. Directly connecting the Z-shaped keels 3 to the ceiling panel 2 with screws is the most convenient method. However, alternatively, reinforcement components 7 can be installed between the Z-shaped keels 3 and the ceiling panel 2 to improve the screw holding force. Multiple reinforcement components 7 are provided and distributed at intervals along the Z-shaped keels 3.

The bottom sides of the zigzag keel 3 are provided with horizontally outwardly extending outer edges 32. The reinforcing component 7 is secured to the two outer edges 32 of the zigzag keel 3 by the two limiting parts 72, and can slide to the appropriate position by the sliding groove 73. Then, the zigzag keel 3, the reinforcing component 7, and the ceiling panel 2 are connected by screws.
