[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily.

[0029] Using decorative gypsum board as the ceiling board of the ceiling module, bending the four sides of the gypsum board towards the opposite side of the decorative surface of the gypsum board by a preset height to shield the connection structures or installation structures such as the furring channels provided on the opposite side of the decorative surface of the gypsum board, effectively beautifying the appearance of the ceiling module, and thus beautifying the appearance of the suspended ceiling system. By providing at least two mutually parallel furring channels on the non-decorative surface of the gypsum board and arranging a number of hanging members at intervals on the furring channels, it is not only convenient for construction and installation, but also can arbitrarily adjust the installation position and installation angle of the ceiling module, effectively expanding the installation methods of the ceiling module, thus greatly expanding the variability of the shape of the suspended ceiling system and increasing the applicable scope and application scenarios of the suspended ceiling system.

[0030] The following will describe in detail the ceiling module, the suspended ceiling system and its construction method provided according to the present invention in conjunction with the accompanying drawings.

[0031] Figure 1 The structural schematic diagram of a specific embodiment of the ceiling module of the present invention is shown. Referring to Figure 1 As shown, the ceiling module 1 includes a gypsum board 11 with a decorative layer and at least two furring channels 12 arranged in parallel on the opposite surface of the decorative surface of the gypsum board 11 (i.e., the non - decorative surface of the gypsum board 11). The gypsum board 11 is used as the decorative panel material of the ceiling module 1, while the furring channels 12 are used to connect with structures such as embedded parts or suspenders on the roof to realize the installation of the ceiling module 1.

[0032] Among them, the four sides of the gypsum board 11 are bent towards the opposite surface of the decorative surface of the gypsum board 11 by a preset height, so that the gypsum board 11 forms an uncovered box - type structure. The bent edges of the gypsum board 11 can cover structures such as the furring channels 12 arranged on its non - decorative surface, effectively beautifying the appearance of the ceiling module 1, so as to ensure that after the construction of the suspended ceiling system is completed, standing under the suspended ceiling system, the appearance of the suspended ceiling system will not be affected by the exposure of structures such as the furring channels 12.

[0033] Furthermore, to ensure the stability of the shape of the edges of the gypsum board 11 after bending, the adjacent ends of the four sides of the gypsum board 11 are fixedly connected by an adhesive, thereby ensuring the shape stability of the ceiling module 1.

[0034] To prevent situations such as gaps or pattern deviations at the edges of the ceiling module 1, in the ceiling module 1 of the present invention, the four sides of the gypsum board 11 are bent by a preset height, rather than using other gypsum board strips to connect with the edges of the gypsum board 11. Specifically, since the gypsum board 11 is a hard material product with a certain thickness, therefore, to facilitate the bending of the edges of the gypsum board 11, V - shaped back grooves are opened at the bending positions of the four sides on the non - decorative surface of the gypsum board 11, and the depth of the V - shaped back grooves is less than the thickness of the gypsum board 11 to prevent piercing the decorative layer of the gypsum board 11 and affecting the appearance of the suspended ceiling module. If, as in this embodiment, the structure formed after the gypsum board 11 is bent is such that its bent edge is perpendicular to the decorative surface of the gypsum board 11, then the angle of the V - shaped back groove is 90 degrees. The bending angle of the edge of the gypsum board 11 of the ceiling module 1 can also be designed as an acute angle or an obtuse angle according to the actual shape of the suspended ceiling system, that is, the included angle between the bent edge of the gypsum board 11 and the decorative surface of the gypsum board 11 is an acute angle or an obtuse angle, and the corresponding V - shaped back groove is set as an obtuse angle or an acute angle.

[0035] Further, to fully achieve the shielding effect after the edges of the gypsum board 11 are bent, the preset height of the four edges of the gypsum board 11 after bending should be greater than the thickness of the furring channel 12. In this embodiment, that is, when the web of the furring channel 12 is connected to the gypsum board 11, the bending height of the four edges of the gypsum board 11 is greater than the flange height of the furring channel 12.

[0036] In this embodiment, the ceiling module 1 further includes an adhesive layer 13. The adhesive layer 13 is located between the gypsum board 11 and the furring channel 12, and the furring channel 12 is fixedly installed on the gypsum board 11 through the adhesive layer 13. Exemplarily, the adhesive layer 13 can be selected from gypsum dough or 3M glue and other adhesives that can realize the fixed connection between the furring channel 12 and the gypsum board 11. At this time, the preset height of the four edges of the gypsum board 11 after bending should be greater than or equal to the sum of the thickness of the adhesive layer 13 and the thickness of the furring channel 12.

[0037] Figure 2 The structural schematic diagram of another specific embodiment of the ceiling module 1 of the present invention is shown. Refer to Figure 2 As shown, in this embodiment, the ceiling module 1 further includes a reinforcement layer 14 and a plurality of reinforcement members 15. The reinforcement layer 14 is located between the gypsum board 11 and the furring channel 12, and is used to reinforce the connection strength and stability between the furring channel 12 and the gypsum board 11. At the same time, it is easier to connect between the reinforcement layer 14 and the gypsum board 11, and between the reinforcement layer 14 and the furring channel 12. Without damaging the decorative layer of the gypsum board 11, it is easier to connect the furring channel 12 and the gypsum board 11 together. Specifically, the reinforcement layer 14 is fixedly connected to the gypsum board 11 through the adhesive layer 13, and the reinforcement layer 14 is fixedly connected to the furring channel 12 through the reinforcement members 15. Exemplarily, the reinforcement members 15 can be selected as countersunk screws, such as flat head self-tapping screws.

[0038] Among them, the reinforcement layer 14 can be selected from gypsum board strips or ordinary paper-faced gypsum boards. For example, in Figure 2 the shown embodiment, the reinforcement layer 14 is an ordinary paper-faced gypsum board with the same shape as the gypsum board 11 and an outer dimension smaller than the bent gypsum board 11.

[0039] Figure 3The structural schematic diagram of the third specific embodiment of the ceiling module 1 is shown. In this embodiment, the reinforcement layer 14 is a gypsum board strip with a width slightly larger than the web width of the covering keel 12. In addition, the ceiling module 1 of this embodiment further includes a plurality of hanging members 16, which are arranged at intervals on the covering keel 12 and are used to connect with connectors such as hanging parts arranged on the roof to complete the installation of the ceiling module 1. Further, the installation height and installation angle of the corresponding position of the ceiling module 1 can be adjusted by adjusting the installation height of different hanging members 16 relative to the roof (that is, adjusting the installation position of the hanging members 16 on the hanging parts or adjusting the suspension length of the hanging parts, etc.), so as to realize the shape transformation of the suspended ceiling system and meet the requirements of the decoration effect. For example, a plurality of hanging members 16 are arranged at intervals on each covering keel 12, and the positions of the hanging members 16 can be adjusted gradually higher or gradually lower in sequence along the extension direction of the covering keel 12, so as to achieve the effect of the inclined installation of the ceiling module 1. If it is necessary to set the ceiling module 1 parallel to the roof, only the installation of each hanging member 16 on the ceiling module 1 needs to be at the same height.

[0040] In Figure 3 In the shown embodiment, the covering keel 12 is selected as a C-shaped keel, and the web of the covering keel 12 is fixedly connected to the gypsum board 11; the hanging member 16 is selected as a rod-shaped fixing member, such as a screw rod, and the hanging member 16 penetrates through the two flange edges of the covering keel 12 to ensure the installation firmness of the hanging member 16 and the installation stability of the ceiling module 1 after connection. In another embodiment, the covering keel 12 can be selected as a keel with other structures, such as an H-shaped keel or a T-shaped keel, and the corresponding hanging member 16 can also be selected as a connector with other structures, as long as a plurality of hanging members 16 are arranged at intervals on the covering keel 12, stably connected, and are convenient for connecting and installing with structures such as hanging parts on the roof.

[0041] The present invention also provides a suspended ceiling system. Figure 4 The structural schematic diagram of a specific embodiment of the suspended ceiling system is shown. Referring comprehensively to Figure 1 and Figure 4As shown in the figure, the suspended ceiling system includes several ceiling modules 1 as described above, and also includes several hanging parts 2 preset on the roof. Several ceiling modules 1 are connected to the hanging parts 2 one by one according to a predetermined rule to form a suspended ceiling system with a predetermined shape. Specifically, the covering keel 12 of the ceiling module 1 is connected to the hanging part 2 one by one. The characteristic of the suspended ceiling system of the present invention is that the adjacent ceiling modules 1 are installed independently and not connected to each other, that is, each ceiling module 1 is independently hoisted. During the actual construction process, the position of the ceiling module 1 can be adjusted by adjusting the connection position between the ceiling module 1 and the hanging part 2, and the installation height and angle of the ceiling module 1 can be adjusted by adjusting the length of the hanging part 2 corresponding to different positions of the ceiling module 1, so that the shape variability of the suspended ceiling system is high, the shape transformation of the suspended ceiling system can be realized, and the requirements of the decoration effect can be met. If it is necessary to set the ceiling module 1 parallel to the roof, only the lengths of the hanging parts 2 need to be adjusted to the same height.

[0042] Specifically, the covering keel 12 can be directly connected to the hanging part 2, or can be connected through other structural members. For example, when installing the ceiling module 1 as shown in Figure 3 the figure, several hanging members 16 are arranged at intervals on the covering keel 12. At this time, the hanging members 16 can be connected to the hanging parts 2 in a one-to-one correspondence by hanging or clamping, etc. to complete the installation of the ceiling module 1.

[0043] Corresponding to the above suspended ceiling system, the present invention also provides a construction method for the suspended ceiling system. Figure 5 The construction flow chart of the construction method is shown in Figure 5 As shown in the figure, the construction method includes the following steps:

[0044] Step S1: Bend the four sides of the gypsum board 11 to a preset height towards the opposite side of the decorative surface of the gypsum board 11, and fixedly connect the adjacent ends of the four sides of the gypsum board 11 through an adhesive.

[0045] Step S2: Fix at least two mutually parallel covering keels 12 on the opposite surface of the decorative surface of the gypsum board 11.

[0046] Step S3: Install the hanging part 2 at a predetermined position on the roof.

[0047] Step S4: Connect the covering keel 12 on the gypsum board 11 to the corresponding hanging part 2 to complete the installation of the ceiling module 1.

[0048] The above steps are the installation steps of one ceiling module 1. According to the above steps, several ceiling modules 1 are installed one by one according to a predetermined rule, and a suspended ceiling system with a predetermined shape can be formed.

[0049] Specifically, step S1 includes: opening a V-shaped back groove at a position on the opposite side of the decorative surface of the gypsum board 11 (i.e., the non-decorative surface of the gypsum board 11) at a preset distance from the edge (or at a position relative to the forming size of the ceiling module 1 on the opposite side of the decorative surface of the gypsum board 11), cutting off the corners at the intersections of adjacent V-shaped back grooves, then bending the edges of the gypsum board 11 one by one along the V-shaped back grooves towards the non-decorative surface of the gypsum board 11, and then bonding and fixing the ends of adjacent bent edges with an adhesive.

[0050] Step S2 specifically includes: coating an adhesive layer 13 at the intended installation position of the ceiling joist 12 on the non-decorative surface of the gypsum board 11, which can be 3M glue with a predetermined thickness and width, or gypsum adhesive masses of a predetermined size distributed at intervals, and then fixing the web of the ceiling joist 12 on the gypsum board 11 through the adhesive layer 13 to form the ceiling module 1.

[0051] In another specific embodiment, when a reinforcement layer 14 (which can be a gypsum board strip or a common paper-faced gypsum board) is further provided between the ceiling joist 12 and the gypsum board 11, step S2 specifically includes:

[0052] Step S21: Fixing and connecting the reinforcement layer 14 to the ceiling joist 12 through a reinforcement member 15;

[0053] Step S22: Smearing the adhesive layer 13 at predetermined positions on the non-decorative surface of the gypsum board 11 at a predetermined interval, which can be 3M glue or gypsum adhesive masses;

[0054] Step S23: Fixing the reinforcement layer 14 with the ceiling joist 12 fixed thereon on the gypsum board 11 through the adhesive layer 13 to form the ceiling module 1.

[0055] When the ceiling module 1 is connected to the hanging member 2 through the suspension member 16, step S2 further includes, before step S21 or after step S23: installing a plurality of suspension members 16 at predetermined positions on the ceiling joist 12. At this time, step S4 specifically includes: connecting the suspension members 16 on the ceiling joist 12 to the corresponding hanging members 2 one by one to complete the installation of the ceiling module 1.

[0056] The construction process of a suspended ceiling system in a specific embodiment is as follows:

[0057] Step S11: Opening 90-degree V-shaped back grooves at a position 50 mm from the four sides on the non-decorative surface of the gypsum board 11 with a decorative layer, removing the residues at the four corners formed by the intersection of the four V-shaped back grooves at the ends, then bending the four sides of the gypsum board 11 along the corresponding V-shaped back grooves towards the non-decorative surface of the gypsum board 11, and fixing the ends of adjacent sides with an adhesive to form an uncovered rectangular box-shaped structure;

[0058] Step S21: Process a C-shaped keel with a length less than or equal to the length of the V-shaped back groove as the ceiling joist 12. Process a gypsum board strip with a width of 100 mm and a thickness of 12 mm as the reinforcement layer 14, and the length of the reinforcement layer 14 is the same as the length of the ceiling joist 12. Fix the gypsum board strip to the web of the ceiling joist 12 with self-tapping screws;

[0059] Step S22: Install a hanger 16 on the ceiling joist 12 at an interval of 400 mm. A through screw can be selected;

[0060] Step S23: Apply a spot of adhesive gypsum paste or 3M glue on the non-decorative surface of the gypsum board 11. Bond and fix the gypsum board strip to the gypsum board 11 with the adhesive gypsum paste or 3M glue, and wait for the adhesive gypsum paste or 3M glue to completely set, then the ceiling module 1 is formed. Among them, adhesive gypsum paste or 3M glue can also be applied to the inner walls around the bent gypsum board 11, and bond and fix the side surfaces of the ceiling joist 12 and the gypsum board strip to the inner walls of the bent gypsum board 11;

[0061] Step S3: Install a hanging piece 2 at a predetermined position on the top (roof or floor slab) of the building structure through expansion bolts;

[0062] Step S4: Connect the ceiling module 1 after the final setting of the adhesive gypsum paste or 3M glue to the corresponding hanging piece 2 one by one according to a predetermined rule, that is, complete the installation of the ceiling module 1 through the one-to-one connection between the hanger 16 on the ceiling module 1 and the hanging piece 2;
