Ceiling structure with arc and manufacturing and mounting method thereof

[0028] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention includes a curved ceiling unit 1, a support rod 2, a keel 3, and a boom 4. The curved ceiling unit 1 is composed of a plurality of single-piece punching plates 6 with a wave-shaped side length section. Therefore, the specific number of the single-piece punching plate 6 is determined according to the actual size of the ceiling. In the curved ceiling unit 1, the single-piece punching plates 6 are arranged in such a way that the arc surface is tangent to the arc surface, and the arc surface and the arc surface tangent between the single-piece punching plates 6 pass through The connecting agent layer 7 is adhered, and the lower end of the rod body of the support rod 2 is radially provided with a groove matching the single-piece punching plate 6. The width of the groove is three millimeters, and the single-piece punching plate The arc surface between 6 and the arc surface are disposed tangentially in the groove. The support rod 2 is hollow and provided with a wire 5, one end I of the wire 5 is bent and hung on the upper end of the support rod 2. On the outer wall, the other end II of the wire 5 extends along the inner wall of the support rod 2 to the lower end of the support rod 2 and passes through the holes 61 and 62 of the single-piece punching plate 6 in sequence. The end II is then folded back along the inner wall of the support rod 2 to the upper end of the support rod 2, and is fixed to the support by a metal lock 8 with a diameter larger than the inner diameter of the support rod 2 together with the end I The upper end of the rod 2 thus realizes the connection between the supporting rod 2 and the curved ceiling unit 1. In addition, the connection between the supporting rod 2 and the curved ceiling unit 1 can also be achieved in other ways, such as It is directly fixed by means of bolts or nuts, etc., but the method of passing through the metal wire is relatively simple and beautiful. The present invention adjusts the extension length of the metal wire 5, and then adjusts the height of the single-piece punching plate 6 relative to the ground, so as to realize the bottom surface of the curved ceiling unit 1 and then present an undulating belt arc Line shape. In the present invention, the metal wire 5 plays the role of hanging and bearing, and the support rod 2 plays the role of positioning and supporting the horizontal plane.

[0029] The upper end of the support rod 2 is externally threaded and passes through the upper and lower end surfaces of the keel 3, and the support rod 2 is fixed to the support rod 2 by two nuts I that match the upper end of the support rod 2. The upper end of keel 3. The lower end of the boom 4 is threaded and passes through the upper end surface of the keel 3, and the boom 4 is fixed to the upper end surface of the keel 3 by two nuts II matching the lower end of the boom 4, An expansion screw 10 is provided at the upper end of the suspension rod 4, and the suspension rod 4 is fixed to the ceiling carrier 9 by the expansion screw 10.

[0030] The present invention is described in detail by using metal wire fixation as a preferred solution. The manufacturing and installation method of the present invention is prefabricated in the factory and installed on the construction site. The manufacturing and installation method includes the following steps:

[0031] ① Prepare the curved ceiling unit 1, support rod 2, keel 3, and boom 4 in the factory. The keel 3 is provided with through holes at equal intervals, wherein the curved ceiling unit 1 includes a number of single pieces Punching plate group, the single-piece punching plate group is formed by bonding two single-piece punching plates 6, the distance between the bonding points on the single-piece punching plate group and the support rod 2 The distances on the keels 3 are equal, and the positions of the bonding points between the single-piece punching plates 6 and the bonding points between the single-piece punching plate groups are staggered. As a preferred solution, The position of the bonding point between the single-piece punching plate group is located at the tangent point of the single-piece punching plate 6 in an arc segment (the highest point on the outer surface);

[0032] ② Stretch and unfold an appropriate number of the curved ceiling units 1 on site according to the area requirements, and connect a plurality of the curved ceiling units 1 to form a combined overall ceiling structure, from top to bottom Fix the boom 4, the keel 3 and the support rod 2;

[0033] ③"After hoisting the curved ceiling unit 1, the metal wire 5 is passed through the curved ceiling unit 1, and then the metal wire 5 is connected and fixed to the support rod 2.

[0034] Wherein, the step of preparing the curved ceiling unit 1 in step ① includes:

[0035] a. Unloading, slitting the aluminum coil into coils of appropriate width;

[0036] b. Punching, continuous punching line for the cut roll material, and automatically cut into equal width blanks according to the design length;

[0037] c. Leveling, the rough part is leveled for the first time through the leveling equipment;

[0038] d. Spraying, the blank after the first leveling is cleaned by pretreatment and then hung and sprayed to obtain the single-piece punching plate 6. The spraying method can be electrostatic powder spraying or fluorocarbon Spraying

[0039] e. Leveling, the single-piece punching plate 6 after spraying is leveled for the second time by leveling equipment;

[0040] f. Bonding, according to the designed grid size and bonding position, the two single-piece punching plates 6 are bonded into a single-piece punching plate group with tape, and then a group of multiple The single-piece punching plate group is bonded by tape to form the curved ceiling unit 1, and the bonding points of the single-piece punching plate group and the bonding points of the curved ceiling unit 1 are staggered equidistantly.

[0041] The preparation step of the keel 3 in the step ① includes: using a steel coil to continuously punch and shape, and then perform a cutting treatment, and then perform a spraying treatment. The through holes on the upper and lower sides of the steel coil need to be aligned to The support rod 2 can pass vertically.

[0042] The invention is suitable for the field of ceiling suspended ceilings.
