Description

Technical Field

[0001] The utility model relates to the field of prefabricated buildings, and particularly relates to a heat-insulating metal thermal insulation and decoration integrated reverse casting wall panel. Background Art

[0002] The thermal insulation and decoration integrated wall panel is widely used in prefabricated buildings. In the thermal insulation and decoration integrated wall panel manufactured by the reverse casting process, the facing materials are mostly facing panels formed by materials such as stone, ceramic tile, and clay board. These facing materials have many disadvantages such as easy cracking, falling off, and water seepage, and the facade effect as an exterior wall is not as good as that of a metal facing panel. However, for the thermal insulation and decoration integrated wall panel with a metal facing panel, the existing technology usually adopts the front casting construction method, which involves more wet operations at the construction site, not only affecting the on-site construction environment but also delaying the construction progress.

[0003] The utility model patent with the publication number of CN207048229U discloses "PC decorative single board reverse casting metal thermal insulation and decoration board and its exterior wall system". The metal thermal insulation and decoration board in this patent is also formed by the reverse casting process, and its structure is as follows: the exterior facing metal board forms a closed groove, heat-insulating material is filled in the groove, a U-shaped connecting piece is laid on the top of the heat-insulating material, and then a perforated board liner is placed on the upper part of the heat-insulating material, enabling the U-shaped connecting piece to pass through the prefabricated holes on the perforated board liner, and the exterior facing metal board and the perforated board liner are fixedly connected by bolts. Reinforcing bars are laid on the perforated board liner, and the U-shaped connecting piece is tied and fixed to the reinforcing bars. Finally, concrete is poured on the upper part of the perforated board liner. The above-mentioned wall panel structure given in this patent cannot completely isolate the cold bridge between the exterior facing metal board and the concrete base wall, thereby affecting the heat insulation and heat preservation effect. Content of the Utility Model

[0004] The utility model discloses a heat-insulating metal thermal insulation and decoration integrated reverse casting wall panel, which is prefabricated and formed in a factory by the reverse casting process, and is provided with a heat-insulating tie piece that can isolate the cold bridge between the metal facing panel and the concrete base wall, and can also prevent the metal facing panel from falling off.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A heat-insulating metal thermal insulation and decoration integrated reverse-cast wall panel, comprising multiple metal decorative panels. The top surface of each metal decorative panel is adhesively bonded with a heat-insulating board, and the metal decorative panel and the heat-insulating board form a thermal insulation and decoration integrated board. Multiple thermal insulation and decoration integrated boards are tiled and spliced horizontally and vertically. The outer surface of the heat-insulating board of each thermal insulation and decoration integrated board faces upward. A heat-insulating bolt with tensile strength is inserted into the horizontally spliced board joint, and a rigid nylon support block is stuffed into the horizontally spliced board joint. A nylon gasket is screwed onto the heat-insulating bolt outside the rigid nylon support block to press the metal decorative panel and the heat-insulating board tightly; a steel support is arranged at the vertically spliced board joint. The steel support and the thermal insulation and decoration integrated boards on the corresponding two sides are tied and fixed with tie straps. The board joint is filled with polyurethane foam material. Concrete is poured on the top surface of the tiled thermal insulation and decoration integrated board, and weather-resistant glue is filled on the side of the metal decorative panel in the horizontal and vertical board joints.

[0007] Further, the heat-insulating bolt comprises a nylon screw rod, a spring steel sheet and a countersunk head self-tapping screw. The spring steel sheet is installed at one end of the nylon screw rod through the countersunk head self-tapping screw, and the spring steel sheet is used for hooking the thermal insulation and decoration integrated board.

[0008] Further, the steel support comprises a third support rod. The length direction of the third support rod is consistent with the length direction of the vertical board joint. Both ends of the third support rod respectively form bifurcations. Each branch of the bifurcation comprises a first support rod and a second support rod. One end of the first support rod is fixedly connected with the third support rod, and the other end of the first support rod is fixedly connected with the second support rod. The first support rod and the second support rod form a bending structure, so as to support the third support rod upward away from the surface of the heat-insulating board.

[0009] Further, strip-shaped holes are formed in the side surface of the thermal insulation and decoration integrated board. The tie straps pass through the strip-shaped holes and then wind around the third support rod of the steel support and are tightened.

[0010] Further, before the concrete is poured on the top surface of the thermal insulation and decoration integrated board, a steel reinforcement cage is erected on the top of the steel support, and the steel support and the steel reinforcement cage are tied and fixed.

[0011] The utility model designs an integrated metal thermal insulation and decoration wall panel by using the reverse casting process. Fully considering the processing characteristics of metal plates, multiple integrated thermal insulation and decoration panels formed by metal decorative panels and thermal insulation panels are first spliced, and then concrete is poured to connect all the integrated thermal insulation and decoration panels into one body. After such design, the size of each metal decorative panel becomes smaller, which is convenient for processing and not prone to deformation. The vertical and horizontal splicing joints formed on the decorative facade also play a role in increasing the aesthetic degree. In addition, the utility model sets a tension member with tensile effect at the spliced board joints. Based on the control analysis of the main negative wind pressure on the reverse casting wall panel designed by the utility model, under negative wind pressure, the decorative panel is in a tensile state. Therefore, it is reasonable to design the tension member (i.e., the heat insulation bolt structure) at the board joints mainly for tensile resistance, which can prevent the metal decorative panel from falling off due to the failure of bonding. Moreover, the tension member designed by the utility model can also serve as a support plate to resist the gravity of the metal decorative panel. The tension member set at the spliced board joints adopts a composite heat insulation material, which has a heat insulation effect and can completely isolate the cold bridge between the metal decorative panel and the cast concrete base wall, improving the thermal insulation performance of the integrated metal thermal insulation and decoration reverse casting wall panel.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] This embodiment discloses an integrated wall panel with a metal sheet as the decorative surface and having heat preservation performance. This wall panel is manufactured by the reverse casting process. Figures 1 to 7 As shown, the integrated reverse-cast wall panel in this embodiment mainly includes a heat preservation and decoration integrated board formed by bonding a metal decorative panel 1 and a heat preservation board 2 (using a heat preservation vacuum insulation board), and concrete 5 poured on the upper part of the heat preservation board 2. Among them, in order to facilitate the processing of the metal decorative panel 1 and reduce the deformation of the metal finish, in this embodiment, a plurality of heat preservation and decoration integrated boards are spliced to form the base board under the concrete 5, that is: each metal decorative panel 1 and heat preservation board 2 are cut and processed according to the design dimensions in the factory, and the heat preservation board 2 is bonded to the back of the metal decorative panel 1 (the side of the metal decorative panel 1 facing the outside is the front, and the side facing the inside is the back). After the two are bonded, a single heat preservation and decoration integrated board is formed. Figure 1 As shown, a plurality of heat preservation and decoration integrated boards are respectively laid flat on the base mold by splicing in the horizontal and vertical directions, with the back of each heat preservation and decoration integrated board facing up. After laying flat, horizontal and vertical board joints are respectively formed between adjacent heat preservation and decoration integrated boards. Tensile tie members (i.e., the heat insulation bolts 9 in this embodiment) are inserted at intervals along the length direction of the horizontal board joint, and steel brackets 3 are arranged at intervals along the length direction of the vertical board joint.

[0023] Continuing from the above, for the structural design of the tie members in the horizontal board joint, in this embodiment, considering that the metal decorative panel 1 is mainly controlled by negative wind pressure and is in a tensile state when used as an external wall panel, in order to avoid the problem of falling off caused by the bonding failure between the metal decorative panel 1 and the heat preservation board 2, the tie members are structurally designed mainly for tensile strength. Figure 6 As shown, the heat insulation bolt 9 is mainly composed of a nylon screw 91, a spring steel sheet 93, and a countersunk head self-tapping screw 94. The spring steel sheet 93 is installed at one end of the nylon screw 91 with the countersunk head self-tapping screw 94. When installing the heat insulation bolt 9, Figure 5 as shown, it is inserted into the horizontal board joint from the side where the heat preservation board 2 is located, and the spring steel sheet 93 is used to hook the side of the heat preservation and decoration integrated board. In order to enable the spring steel sheet 93 to hook, holes can be pre-drilled in the folded edge on the side of the metal decorative panel 1. After installing the heat insulation bolt 9, a hard nylon support block 8 with internal threads is screwed onto the nylon screw 91, and the hard nylon support block 8 fills the horizontal board joint where the heat insulation bolt 9 is located. Then, a nylon gasket 92 with internal threads is screwed onto the nylon screw 91 to press the heat preservation board 2 and the metal decorative panel 1 tightly. The tie members installed in the horizontal board joint not only have the functions of heat insulation and tensile strength, but can also serve as a support plate to resist the gravity of the metal decorative panel 1.

[0024] For the steel bracket 3 provided at the vertical plate joint, in the structural design of the steel bracket 3 in this embodiment, in addition to realizing the connection function of adjacent thermal insulation and decoration integrated boards, it also serves as a steel bar stool during the pouring of the concrete 5. The structure of the steel bracket 3 is as Figure 7 shown. The middle part thereof is the third rod 33. Both ends of the third rod 33 are respectively formed with bifurcations. The bifurcations are composed of two branches. Each branch is formed by connecting the first rod 31 and the second rod 32. One end of the first rod 31 is fixedly connected to the third rod 33, and the other end of the first rod 31 is fixedly connected to the second rod 32. A bending structure is formed at the connection of the first rod 31 and the second rod 32. When placing the steel bracket 3, as Figure 4 shown, make the length direction of the third rod 33 consistent with the length direction of the vertical plate joint. One of the branches of the bifurcation is placed on one of the spliced thermal insulation and decoration integrated boards, and the other branch is placed on the other thermal insulation and decoration integrated board, and the third rod 33 is in an upwardly convex shape. After placing the steel bracket 3, tie and fix the steel bracket 3 to the corresponding thermal insulation and decoration integrated boards on both sides with nylon straps 4, thus forming a pulling point. The specific method is as follows: strip-shaped holes are pre-opened on the side surface of the thermal insulation and decoration integrated board. After passing the nylon strap 4 through the strip-shaped holes, it is wound around the third rod 33 of the steel bracket 3 and tightened.

[0025] After the fixing of the steel bracket 3 is completed, fill the polyurethane foam material 6 along the vertical plate joint and the horizontal plate joint respectively to level the plate joints on the inner side of the thermal insulation and decoration integrated board. Then, erect a steel reinforcement cage on the top of the steel bracket 3, tie and fix the steel bracket 3 to the steel reinforcement cage, and then pour the concrete 5 on the top surface of all the spliced thermal insulation and decoration integrated boards. Finally, fill the horizontal plate joint and the vertical plate joint on the side where the metal decorative panel 1 is located with weather-resistant glue 7 to seal the outer gaps.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
