DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0050] Embodiment 1:

[0051] like Figure 1 - Fig.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 outside 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 on a straight line) of suspension members 1. A plurality of longitudinal beams 2 are provided. The plurality of longitudinal beams 2 are distributed in parallel and spaced apart. The spacing 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 larger force in the vertical direction to meet the installation requirements of the foam concrete insulation board layer 5 and the buckled metal plate 6. A plug hole 4a is opened on the surface of the arched metal plate 4, 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 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 are of standard length 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 located 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 in sequence, 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 of the arched metal plate 4 is supported on the top of the first side panel 204), and 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, and the snap-fitting metal plate 6 is snapped into the gap between the second side panel 205 and the third side panel 206, wherein the width of the third side panel 206 is relatively small, which is convenient for the snap-fitting 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 clamping 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 limiting fasteners 3, wherein the arched metal plate 4 pushes the two adjacent longitudinal beams 2 to move outward, and the distance limiting fastener 3 is 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 of the foam concrete insulation board layer 5 is 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 the two 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 are contracted inwardly over the third side plate 206 and inserted into 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 with 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), and the top of the buckled metal plate 6 is fixedly connected with an inverted "T"-shaped member 6b. The top of the inverted "T"-shaped member 6b is provided with a clamping opening 6b1. The shape of the clamping opening 6b1 is a hyperbola shape, and 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 the vertical plate member 4b is clamped and fixed by the middle of the clamping opening 6b1.

[0062] By designing structures such as the vertical plate member 4 b and the inverted “T”-shaped member 6 b, 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, a plurality of reverse flanges 702 are arranged on the side of the screw 701, the reverse flanges 702 are inclined downward, and the diameters of the plurality of reverse flanges 702 increase from top to bottom. When installing the foam concrete insulation board layer 5, the top end of the screw 701 is pierced upward through the foam concrete insulation board layer 5, and then the reverse flange 702 of the screw 701 is inserted into the inside of the socket 4a. Since the reverse 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 nail 103 and an undercut assembly 104 .

When in use, the relative position of the adjusting member 102 and the fixing member 101 is adjusted to make the height of the adjusting member 102 appropriate (a level meter can be used for auxiliary judgment), and then the fixing nail 103 is tightened to fasten the adjusting member 102 and the fixing member 101. The inverted buckle component 104 is installed at the bottom end of the adjusting member 102. The inverted buckle component 104 is used to hang the longitudinal beam member 2. Specifically, the hinged plates of the inverted buckle component 104 are inserted into the tops of both sides of the U-shaped profile 201 and are bent inward to form the inverted parts 202. The inverted parts 202 cooperate with the inverted buckle component 104 to hang the longitudinal beam member 2, and the two sides of the U-shaped profile 201 limit the hinged plates of the inverted buckle component 104 from opening outward, thereby forming a locking structure.

When installing the fixing member 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 101a upwards to make the small hole of the hanging hole 101g 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 with sliding arm members 102b, the sliding arm members 102b are processed by bending technology, the vertical part 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 102 corresponding to the long hole 101c, the side of the plate body 102a is fixedly connected with a nut member 102d concentric with the through hole 102, and the fixing nail 10 3 is located inside the long hole 101c and the through hole 102, and the fixing nail 103 is threadedly matched with the nut member 102d; the bottom end of the plate body 102a is bent to form a first hinge 102e and a second hinge 102f, the first hinge 102e and the second hinge 102f extend toward the two sides of the plate body 102a respectively, and 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 integrally formed by plate punching and bending processes, and its production is simple 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 .
