[0048] Such as Figures 1 to 9As shown in the figure, the present application proposes a reinforced truss concrete thin-walled plate with an energy-saving and heat-insulating integrated structure, which includes a support assembly 100. The support assembly 100 includes an upper chord steel bar 101, a lower chord steel bar 102, web bars 103, a bottom formwork 104, and a steel mesh 105. The web bars 103 are connected to the bottom formwork 104, and the steel mesh 105 is located inside the bottom formwork 104. It also includes a heat-insulating assembly 200. The heat-insulating assembly 200 includes a fixed shell 201, a first filling plate 202, a heat-insulating plate 203, a second filling plate 204, a heat-insulating cavity 205, and a heat-insulating chamber 207. The bottom formwork 104 is formed by pouring concrete and has a rectangular groove at the bottom. The fixed shell 201 is fixedly connected inside the rectangular groove. A heat-insulating cavity 205 is provided inside the fixed shell 201. The heat-insulating cavity 205 is used to place the filling plates and the heat-insulating plate 203. The first filling plate 202 and the second filling plate 204 on both sides of the heat-insulating plate 203 can reduce the heat transfer on both sides of the filling plates, thereby achieving the effect of heat insulation. The heat-insulating plate 203 is provided with a plurality of penetrating polygonal holes. The first filling plate 202 and the second filling plate 204 are respectively located on the upper and lower sides of the heat-insulating plate 203. Grooves are provided on the side walls of the first filling plate 202 and the second filling plate 204 close to the heat-insulating plate 203. The heat-insulating chambers 207 are formed by the grooves on both sides of the heat-insulating plate 203. The heat-insulating chambers 207 on both sides of the heat-insulating plate 203 are communicated through the polygonal holes. The heat-insulating chamber 207 is a closed hollow chamber, and the air inside the heat-insulating chamber 207 is not connected to the outside, so that the heat-insulating chamber 207 can store a certain amount of heat and thus achieve the effect of heat preservation.

[0049] Preferably, fixing covers 106 are fixed at both ends of the bottom formwork 104. Connecting pins 107 are fixed on the side walls of the fixing covers 106 facing the bottom formwork 104, and corresponding connecting holes are provided on the side walls of the bottom formwork 104. By inserting the connecting pins 107 into the connecting holes on the bottom formwork 104 and then fixing the fixing covers 106 on the side walls of the bottom formwork 104 with concrete slurry, the heat-insulating cavity 205 is formed into a closed chamber. The fixing cover 106 is a hollow rectangular plate, and a foam board for heat preservation is filled inside the fixing cover 106. The upper and lower ends of the fixing cover 106 are fixed on the building, and the foam board inside the fixing cover 106 can play a heat-preserving role, thereby preventing heat from being transferred from the connection between the thin-walled plate and the building to the outside.

[0050] Preferably, the first filling plate 202 and the second filling plate 204 are rock wool boards. The rock wool boards have a low thermal conductivity, so that the heat transfer speed on both sides of the first filling plate 202 and the second filling plate 204 is slowed down. When the thin-walled plate is in use, the first filling plate 202 and the second filling plate 204 can block the heat on one side of the thin-walled plate, preventing the heat from being transferred to the other side of the thin-walled plate, thereby achieving the effect of heat insulation.

[0051] Preferably, a support frame 208 is fixed in the grooves on the first filling plate 202 and the second filling plate 204. The support frame 208 can support and fix the first filling plate 202 and the second filling plate 204, preventing the first filling plate 202 or the second filling plate 204 from deforming when the thin wall plate is subjected to external forces. The support frame 208 is a concave plate, and the support frame 208 contacts the upper and lower sides of the heat insulation plate 203 respectively.

[0052] Preferably, a fixing buckle 206 is fixedly connected inside the fixing shell 201. The fixing buckle 206 is two rectangular rods, and the fixing buckle 206 is located on both side walls of the heat preservation cavity 205 respectively. The fixing buckle 206 is used to support the heat insulation plate 203, so that the heat insulation plate 203 is located in the middle position inside the heat preservation cavity 205, which is convenient for placing the first filling plate 202 and the second filling plate 204 on both sides of the heat insulation plate 203.

[0053] Preferably, the fixing shell 201 is a rectangular hollow plate, which is made of concrete. After the concrete solidifies, the fixing shell 201 and the bottom mold 104 are fixedly connected together. Concrete slurry is applied to the contact surfaces of the fixing shell 201 and the bottom mold 104, so that the fixing shell 201 and the bottom mold 104 are closely connected, preventing cracks from appearing at the connection between the fixing shell 201 and the bottom mold 104. Multiple steel bars for enhancing the strength of the fixing shell 201 are inserted into the fixing shell 201. The fixing buckle 206 is fixed in the heat preservation cavity 205 by concrete slurry, making the fixing shell 201 and the fixing buckle 206 form a whole.

[0054] Preferably, the heat insulation plate 203 is formed by concrete casting. There are multiple sealed micro air holes inside the heat insulation plate 203. The micro air holes located inside the heat insulation plate 203 can reduce the weight of the heat insulation plate 203 and also play a certain heat preservation role.

[0055] Preferably, the shape of the fixing buckle 206 is the same as the shape of the groove on the side wall of the heat insulation plate 203. Before fixedly connecting the fixing shell 201 and the bottom mold 104, the heat insulation plate 203 is inserted into the fixing shell 201, so that the groove on the side wall of the heat insulation plate 203 fits with the fixing buckle 206. Before connecting the heat insulation plate 203 to the inside of the fixing shell 201, concrete slurry is applied to the groove on the side wall of the heat insulation plate 203. The heat insulation plate 203 and the fixing buckle 206 are fixedly connected through the concrete slurry, and then the heat insulation plate 203 is fixed inside the fixing shell 201.

[0056] Preferably, the contact surfaces of the first filling plate 202 and the second filling plate 204 with the fixed shell 201 are smeared with concrete slurry, and then the first filling plate 202 and the second filling plate 204 are inserted into the gap between the fixed shell 201 and the heat insulation plate 203; the first filling plate 202 and the second filling plate 204 are both fixed in the fixed shell 201 through the concrete slurry; the first filling plate 202 and the second filling plate 204 are respectively attached to the upper and lower side surfaces of the heat insulation plate 203, and the concrete slurry is smeared on the joint surfaces with the heat insulation plate 203, so that the first filling plate 202 and the second filling plate 204 are respectively adhered to the upper and lower sides of the heat insulation plate 203.

[0057] When the steel bar truss concrete thin-walled plate with an energy-saving structure and thermal insulation integration in the embodiment of the present application is actually used:

[0058] First, the web bars 103 are poured into the internal of the bottom mold 104, and the upper chord steel bars 101 and the lower chord steel bars 102 are welded to the web bars 103. After the bottom mold 104 is formed, the fixed shell 201 is fixed to the bottom of the bottom mold 104. Before the fixed shell 201 and the bottom mold 104 are fixedly connected, the heat insulation plate 203 is slidably connected into the fixed shell 201 and fixed first, and then the first filling plate 202 and the second filling plate 204 are connected to the upper and lower sides of the heat insulation plate 203. The heat insulation cavity 207 formed between the heat insulation plate 203 and the filling plates located in the fixed shell 201 can play a heat insulation effect. The first filling plate 202 and the second filling plate 204 are rock wool plates, which can reduce the heat transfer on both sides of the filling plates and thus achieve the heat insulation effect. The hollow fixed shell 201 can reduce the weight of the thin-walled plate. The heat insulation and heat preservation effects are achieved through the combined action of the filling plates and the heat insulation plate 203 in the fixed shell 201.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
