[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] Example 1:

[0051] like Figure 1 - Figure 10 As shown, an embodiment of the present invention provides an energy-saving and heat-insulating assembled ceiling structure, which is used for decorating the ceiling to ensure the stable installation of the insulation board ceiling structure (including the foam concrete insulation board layer 5), specifically including: a longitudinal beam 2, an arched metal plate 4, a foam concrete insulation board layer 5 and a buckled metal plate 6.

[0052] In this embodiment, the arched metal plate 4, the foam concrete insulation board layer 5 and the interlocking metal plate 6 constitute a three-layer insulation board, which can effectively reduce the flow of indoor air and external air and contribute to indoor insulation. The longitudinal beam 2 is horizontally suspended by the suspension member 1. The top of the suspension member 1 can be installed on the cross beam or directly on the indoor roof. It is generally fixed with self-tapping screws / expansion bolts. Each longitudinal beam 2 corresponds to a row (multiple distributed in a straight line) of suspension members 1. There are multiple longitudinal beams 2, and the multiple longitudinal beams 2 are distributed in parallel and spaced apart. The distance between two adjacent longitudinal beams 2 corresponds to the three-layer insulation board.

[0053] During the installation process, the arched metal plate 4 is installed between two adjacent longitudinal beams 2. The arch of the arched metal plate 4 is upward (or the opening is downward), so that it can withstand a large force in the vertical direction, meeting the installation requirements of the foam concrete insulation board layer 5 and the buckled metal plate 6. The surface of the arched metal plate 4 is provided with a socket 4a, and the foam concrete insulation board layer 5 is fixed to the bottom of the arched metal plate 4 by a one-way buckle 7. In this structure, the gravity of the foam concrete insulation board layer 5 is completely borne by the arched metal plate 4, and the buckled metal plate 6 is buckled between the two adjacent longitudinal beams 2, and the buckled metal plate 6 is located below the foam concrete insulation board layer 5.

[0054] The present invention meets the use requirements of the insulation board by designing a three-layer assembled insulation board composed of an arched metal plate 4, a foam concrete insulation board layer 5 and a buckled metal plate 6; the arched metal plate 4 is installed between two adjacent longitudinal beams 2, and relying on the arched structure of the arched metal plate 4, it can withstand a large force in the vertical direction, meeting the installation requirements of the foam concrete insulation board layer 5 and the buckled metal plate 6, the buckled metal plate 6 is buckled between the two adjacent longitudinal beams 2, and the bottom of the buckled metal plate 6 is smooth and flat, meeting the beautification requirements of the suspended ceiling. The design of the overall structure makes the insulation board structure stable, not easy to collapse, and has a longer service life.

[0055] The lengths of the arched metal plate 4, the foamed concrete insulation board layer 5 and the interlocking metal plate 6 are determined according to actual conditions. The foamed concrete insulation board layer 5 is cut and can be longer. The arched metal plate 4 and the interlocking metal plate 6 adopt standard lengths and have better versatility.

[0056] In one embodiment, the longitudinal beam member 2 includes: a U-shaped profile 201, the opening of the U-shaped profile 201 faces upward, and the tops of both sides of the U-shaped profile 201 are bent inward to form undercut portions 202, and the undercut portions 202 correspond to the bottom end of the suspension member 1. Both side surfaces of the U-shaped profile 201 are provided with transversely arranged disassembly holes 203, which are used in conjunction with the suspension member 1. The outer sides of the two side surfaces of the U-shaped profile 201 and below the disassembly holes 203 are fixedly connected with a first side panel 204, a second side panel 205, and a third side panel 206 from top to bottom, wherein the width of the first side panel 204 and the second side panel 205 is twice the width of the third side panel 206.

[0057] In the design of the longitudinal beam 2, the top of the first side panel 204 is used to support the arched metal plate 4 (the arched metal plate 4 is arched upward, and the side edges of the arched metal plate 4 are supported on the top of the first side panel 204). The gap formed between the first side panel 204 and the second side panel 205 is used to clamp the two side edges of the foam concrete insulation board layer 5. The snap-fitting metal plate 6 is snapped into the gap between the second side panel 205 and the third side panel 206. The width of the third side panel 206 is relatively small, which facilitates the snap-fit installation of the snap-fitting metal plate 6.

[0058] In one embodiment, a distance limiting fastener 3 is installed between two adjacent longitudinal beams 2, and both ends of the distance limiting fastener 3 are bent downward to form a card foot. The end of the distance limiting fastener 3 is inserted into the interior of the U-shaped profile 201. The distance between the two adjacent longitudinal beams 2 is limited by the installed multiple distance limiting fasteners 3, wherein the arched metal plate 4 pushes the two adjacent longitudinal beams 2 to move toward the outside, and the distance limiting fastener 3 can be tightened inward. The distance limiting fastener 3 cooperates with the arched metal plate 4 to ensure the stability of the longitudinal beam 2.

[0059] In one embodiment, the side edges of the foam concrete insulation board layer 5 are located in the area between the first side panel 204 and the second side panel 205. When installing the foam concrete insulation board layer 5, glue can be applied to both sides of the foam concrete insulation board layer 5 so that both sides of the foam concrete insulation board layer 5 can be glued and fixed to the area between the first side panel 204 and the second side panel 205, thereby ensuring the stability of the installation of the foam concrete insulation board layer 5.

[0060] In one embodiment, guiding bevels 6a are provided on both sides of the snap-fitting metal plate 6, and the guiding bevels 6a are snap-fitted into the area between the second side plate 205 and the third side plate 206. The top of the guiding bevel 6a is designed to be inclined. When the user pushes the snap-fitting metal plate 6 upward, the guiding bevel 6a is squeezed on the inner side of the third side plate 206, thereby changing the direction of the squeezing force, so that the guiding bevel 6a is subjected to a reverse thrust in the horizontal direction, so that the two sides of the snap-fitting metal plate 6 shrink inward over the third side plate 206 and are stuck in the area between the second side plate 205 and the third side plate 206.

[0061] In one embodiment, the bottom of the arched metal plate 4 is fixedly connected to a vertical plate member 4b. When the foam concrete insulation board layer 5 is installed, the bottom of the vertical plate member 4b passes through the foam concrete insulation board layer 5 (directly punctures the foam concrete insulation board layer 5). The top of the buckled metal plate 6 is fixedly connected to an inverted "T"-shaped member 6b. The top of the inverted "T"-shaped member 6b is provided with a clamping opening 6b1. The clamping opening 6b1 is in the shape of a hyperbola. The top of the clamping opening 6b1 has a guiding oblique opening. The vertical plate member 4b is inserted into the inner side of the clamping opening 6b1 and is clamped and fixed by the middle part of the clamping opening 6b1.

[0062] By designing structures such as the vertical plate 4b and the inverted "T"-shaped member 6b, the connection between the buckled metal plate 6 and the arched metal plate 4 is achieved, thereby further improving the stability of the connection of the buckled metal plate 6.

[0063] In one embodiment, the one-way fastener 7 includes: a screw 701, and a plurality of inverted flanges 702 are provided on the side of the screw 701. The inverted flanges 702 are inclined downward, and the diameters of the plurality of inverted flanges 702 increase from top to bottom. When installing the foam concrete insulation board layer 5, the top end of the screw 701 is pointed upward to pierce the foam concrete insulation board layer 5, and then the inverted flange 702 of the screw 701 is inserted into the interior of the socket 4a. Since the inverted flange 702 is inclined downward, it is easy to insert into the socket 4a, but not easy to be pulled out.

[0064] In one embodiment, the suspending member 1 includes a fixing member 101 , an adjusting member 102 , a fixing pin 103 and an undercut assembly 104 .

[0065] The top of the fixing member 101 can be installed on the beam or directly on the indoor roof. The adjusting member 102 is fixedly connected to the fixing member 101 by the fixing nail 103, and the fixing position of the adjusting member 102 and the fixing member 101 is adjustable. When in use, adjust the relative position of the adjusting member 102 and the fixing member 101 so that the height of the adjusting member 102 is appropriate (a spirit level can be used for auxiliary judgment), and then tighten the fixing nail 103 to fasten the adjusting member 102 and the fixing member 101. The inverted buckle assembly 104 is installed at the bottom end of the adjusting member 102. The inverted buckle assembly 104 is used to hang the longitudinal beam member 2. Specifically, the hinge plates of the inverted buckle assembly 104 are inserted into the tops of both sides of the U-shaped profile 201, which are bent inward to form inverted parts 202. The inverted parts 202 cooperate with the inverted buckle assembly 104 to suspend the longitudinal beam member 2, and the two sides of the U-shaped profile 201 limit the hinge plates of the inverted buckle assembly 104 from opening outward, thereby forming a locking structure.

[0066] In one embodiment, the fixing member 101 includes: an L-shaped main connecting frame 101a and an L-shaped auxiliary connecting frame 101e; wherein, the horizontal portion of the L-shaped main connecting frame 101a is provided with a first connecting hole 101b, which can be fixed with screws or expansion bolts, and the vertical portion of the L-shaped main connecting frame 101a is provided with a long hole 101c, and the fixing nail 103 can slide inside the long hole 101c, and the vertical portion of the L-shaped main connecting frame 101a is fixedly connected with a connecting buckle 101d above the long hole 101c, and the connecting buckle 101d is riveted or welded, and the L-shaped auxiliary connecting frame 101e serves to auxiliary strengthen the L-shaped main connecting frame.

The vertical part of the L-shaped auxiliary connecting frame 101e is provided with a hanging hole 101g. The hanging hole 101g includes a large hole and a small hole that are smoothly connected, and the small hole is located below the large hole. When installing the fixing part 101, first install the L-shaped main connecting frame 101a, then align the large hole of the hanging hole 101g with the connecting buckle 101d, and then slide the L-shaped auxiliary connecting frame 101e upwards so that the small hole of the hanging hole 101g is stably stuck on the connecting buckle 101d.

[0067] In one embodiment, the adjusting member 102 includes: a plate body 102a, both sides of the plate body 102a are fixedly connected to a sliding arm member 102b, the sliding arm member 102b is processed by a bending process, the vertical portion of the L-shaped main connecting frame 101a is located inside the two sliding arm members 102b and slides together, the side of the plate body 102a is provided with a through hole 102c corresponding to the long hole 101c, the side of the plate body 102a is fixedly connected to a nut member 102d concentric with the through hole 102c, and the fixing nail 101a is fixed to the plate body 102a. 3 is located inside the long hole 101c and the through hole 102c, and the fixing nail 103 is threadedly engaged with the nut 102d; the bottom end of the plate body 102a is bent to form a first hinge 102e and a second hinge 102f, which extend toward the two sides of the plate body 102a respectively. A transverse hole 102g is opened on the side of the plate body 102a, and the first hinge 102e and the second hinge 102f are used to install the undercut assembly 104.

[0068] The plate body 102a is entirely manufactured by plate punching and bending processes, and is simple to manufacture and can be put into mass production.

[0069] In one embodiment, the undercut assembly 104 includes a first hinge plate 104 a , a second hinge plate 104 b , and a transverse rubber block 104 c .

[0070] A first transverse shaft is fixedly provided at the bottom end of the first hinge plate 104a, and the first transverse shaft is welded and fixed to the bottom end of the first hinge plate 104a. The first transverse shaft is rotatably connected to the first hinge 102e. The first transverse shaft is provided with a limiting end to prevent the first transverse shaft and the first hinge 102e from sliding axially. A second transverse shaft is fixedly provided at the bottom end of the second hinge plate 104b, and the second transverse shaft is rotatably connected to the second hinge 102f. The second transverse shaft is welded and fixed to the second hinge plate 104b. The second transverse shaft is provided with a limiting end.

[0071] like Figure 7 In the state shown in FIG, the bottom end of the undercut assembly 104 is narrow, which can be easily inserted into the U-shaped profile 201. During this process, the horizontal rubber block 104c is squeezed and deformed. When the undercut assembly 104 is fully inserted into the U-shaped profile 201, the back-shape force of the horizontal rubber block 104c causes the first hinge plate 104a and the second hinge plate 104b to rotate toward both sides. The top ends of the first hinge plate 104a and the second hinge plate 104b are inverted in the undercut portion 202, thereby achieving a stable connection between the undercut assembly 104 and the longitudinal beam 2.
