Description

Technical Field

[0001] The present application relates to the technical field of thermal insulation boards, and in particular to an exterior wall composite thermal insulation board and a production process. Background Art

[0002] External wall insulation board is a board used to be installed on the outer surface of a house to provide insulation. It is widely used on the exterior walls of buildings such as villas, self-built houses and sentry boxes. Existing insulation boards include metal decorative insulation boards, which are also a type of external wall insulation board. After installation, it is not necessary to modify the surface, so it is more convenient. However, during the installation process, the metal decorative insulation board is directly fixed to the surface of the external wall by expansion screws, which makes it easy to have a gap between the metal decorative insulation board and the wall. Summary of the invention

[0003] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide an exterior wall composite insulation board and a production process, which have the advantage of being able to effectively reduce the probability of gaps being easily generated between the metal decorative insulation board and the wall.

[0004] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0005] The present application discloses an exterior wall composite thermal insulation board, comprising a decorative outer layer, a thermal insulation outer layer, a reinforcement layer, a thermal insulation inner layer and an adhesive layer, wherein the reinforcement layer comprises a connecting plate and an elastic layer, wherein the elastic layer is located between the thermal insulation outer layer and the thermal insulation inner layer, wherein the connecting plates are located at both ends of the elastic layer, wherein the connecting plates are located at one end of the thermal insulation inner layer, wherein the connecting plates are used to be connected to a wall, wherein the adhesive layer is coated with an adhesive for being connected to a wall, wherein when the connecting plates are connected to the wall, the elastic layer is in a stretched state to apply pressure to the thermal insulation inner layer toward the wall.

[0006] By adopting the above technical solution, during the installation process, the adhesive is coated on the adhesive layer, and then the adhesive layer is brought into contact with the wall, and the connecting plate and the wall are connected. During the process of connecting the connecting plate and the wall, the elastic layer is stretched, so that the elastic layer applies a force toward the wall to the thermal insulation inner layer, thereby making the connection effect between the adhesive layer and the wall better. The adhesive is subjected to pressure and can fill the gap, thereby reducing the probability of gap generation.

[0007] In a preferred example, the present application can be further configured as follows: the elastic layer includes elastic horizontal bars and elastic vertical bars, the elastic horizontal bars and the elastic vertical bars are staggered, and both ends of the elastic horizontal bars and the elastic vertical bars are fixedly connected to the connecting plates.

[0008] By adopting the above technical solution, the presence of the staggered elastic horizontal strips and elastic vertical strips can exert pressure on the thermal insulation inner layer in both the horizontal and vertical directions, thereby achieving a better connection effect between the adhesive layer and the wall.

[0009] In a preferred example, the present application can be further configured as follows: the reinforcement layer is further provided with reinforcement rods, and the reinforcement rods are used to connect the relatively arranged connection plates.

[0010] By adopting the above technical solution, since the elastic layer is made of flexible material, the presence of the reinforcing rod can support the connecting plate, making the installation process more convenient.

[0011] In a preferred example, the present application can be further configured as follows: the connecting plate and the reinforcing rod are in point contact.

[0012] By adopting the above technical solution, since the connecting plate and the reinforcing rod are in point contact, during use, applying a certain force to the connecting rod can break the connection, thereby making installation more convenient.

[0013] In a preferred example, the present application can be further configured as follows: an upper receiving groove for receiving the elastic layer is provided on the thermal insulation outer layer, and a lower receiving groove for receiving the reinforcing rod is provided on the thermal insulation inner layer.

[0014] By adopting the above technical solution, the existence of the upper receiving groove makes it possible to position the elastic layer, reducing the probability of dislocation of the elastic layer during the production process. At the same time, the existence of the lower receiving groove makes it possible to position the reinforcing rod, reducing the probability of dislocation of the reinforcing rod during the production process.

[0015] In a preferred example, the present application can be further configured as follows: the connecting plate includes an upper plate body and a lower plate body, the upper plate body can move toward the lower plate body under the action of external force, the elastic layer includes a connecting upper end and a connecting lower end, the connecting upper end is located between the upper plate body and the lower plate body, and the connecting lower end is located on the surface where the lower plate body contacts the wall.

[0016] By adopting the above technical solution, during the installation process, since the upper end of the connection is located between the upper plate body and the lower plate body, and the upper plate body can move toward the lower plate body under the action of external force, when the connecting plate is installed on the wall through the expansion screws, the upper plate body is subjected to force and moves toward the lower plate body, exerting pressure on the upper end of the connection. At the same time, under the action of the expansion screws, the lower plate body moves toward the wall, thereby exerting force on the lower end of the connection. Therefore, during use, both the upper end and the lower end of the connection are subjected to pressure, thereby making the fixing effect of the elastic layer better, and being able to maintain good pressure on the thermal insulation inner layer.

[0017] In a preferred example, the present application can be further configured as follows: it also includes a caulking strip, the caulking strip includes a decorative layer and a thermal insulation layer, and the thermal insulation layer is provided with a connecting groove for accommodating the reinforcing rod.

[0018] By adopting the above technical solution, the presence of the caulking strip can cover the connecting plate, so that the insulation wall is formed as a whole, thereby achieving a good insulation effect and reducing the probability of aging of the connecting plate and the elastic layer due to environmental reasons during use.

[0019] The present application also discloses a production process for an exterior wall composite insulation board, comprising the following steps: grooving: opening corresponding grooves on the insulation outer layer, insulation inner layer and insulation layer; gluing: applying glue in the grooves; reinforcing layer connection: installing the elastic layer in the groove of the insulation outer layer, and installing the reinforcing rod in the groove of the insulation inner layer; board layer splicing: connecting the decorative outer layer, insulation outer layer, insulation inner layer and adhesive layer together in sequence; elastic layer connection: connecting the elastic layer and the connecting plate.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-Figure 4The present application discloses an exterior wall composite insulation board, including a main board body and a caulking strip 4, and the column board body includes a decorative outer layer 11, an insulating outer layer 12, a reinforcing layer, an insulating inner layer 13 and an adhesive layer 14 arranged in sequence. The reinforcing layer includes a connecting plate 31 and an elastic layer 2, and the elastic layer 2 includes an elastic longitudinal strip 21 and an elastic transverse strip 22, and the elastic longitudinal strip 21 and the elastic transverse strip 22 are integrally formed and made of rubber. The elastic transverse strip 22 is perpendicular to the elastic longitudinal strip 21. Both ends of the elastic longitudinal strip 21 and the elastic transverse strip 22 are fixedly connected with the above-mentioned connecting plate 31. The connecting plate 31 is located on the outside of the main board body. The adhesive layer 14 can be a mesh cloth.

[0027] During the installation process, an adhesive is applied to the bonding layer 14, and the main body is placed at a suitable position on the wall. Then, the connecting plate 31 is connected to the wall by expansion bolts. After the connecting plate 31 is installed on the wall, the elastic longitudinal strip 21 and the two ends of the elastic transverse strip will be subjected to tension, thereby causing the elastic transverse strip 22 and the elastic longitudinal strip 21 to be stretched. During the stretching process of the elastic transverse strip 22 and the elastic longitudinal strip 21, since the stretching direction is toward the wall, during this process, the elastic transverse strip 22 and the elastic longitudinal strip 21 will apply a force toward the wall to the thermal insulation inner layer 13, thereby causing the bonding layer 14 to be subjected to a force toward the wall, so that the adhesive will fill the gap after being subjected to the force. After the main body is installed, due to the presence of the connecting plate 31, the adjacent main bodies do not contact each other, so the caulking strip 4 is installed between the adjacent main bodies and in contact with them, thereby forming a complete thermal insulation wall.

[0028] The connecting plate 31 includes an upper plate body 311 and a lower plate body 312, a fixing column 313 is fixedly connected to the lower plate body 312, and an anti-slipping tooth 314 is provided on the fixing column 313, and a fixing hole 315 is provided on the upper plate body 311 for the fixing column 313 to pass through, and the anti-slipping tooth 314 is located in the fixing hole 315 and abuts against the hole wall of the fixing hole 315, and both ends of the elastic horizontal bar 22 and the elastic longitudinal bar 21 are provided with a connecting upper end and a connecting lower end, and the connecting upper end is located between the upper plate body 311 and the lower plate body 312 and is fixedly connected therebetween, and the connecting lower end is located between the lower plate body 312 and the wall and is fixedly installed on the side of the lower plate body 312 facing the wall. In this embodiment, the upper plate body 311, the lower plate body 312, the fixing column 313 and the anti-slipping tooth 314 are all made of plastic.

[0029] During the installation process, the expansion screw applies force to the upper plate body 311, causing the upper plate body 311 to move toward the lower plate body 312, thereby enabling pressure to be applied to the upper end of the connection, thereby improving the connection effect of the upper end of the connection. At the same time, in the process of the upper plate body 311 moving toward the lower plate body 312, the anti-slip teeth 314 move out of the fixing holes 315 and deform, thereby fixing the upper plate body 311.

[0030] Since the elastic horizontal strip 22 and the elastic vertical strip 21 are made of rubber, they have no supporting effect on the connecting plate 31. Therefore, the reinforcing layer also includes a reinforcing rod 32. The reinforcing rod 32 is cylindrical and located between two connecting plates 31 arranged opposite to each other. The two ends of the reinforcing rod 32 are respectively fixedly connected to the two connecting plates 31. The two ends of the reinforcing rod 32 are connected to the lower plate body 312. The two ends of the reinforcing rod 32 are conical. An upper receiving groove for accommodating the elastic layer 2 is provided on the thermal insulation outer layer 12, and a lower receiving groove for accommodating the reinforcing rod 32 is provided on the thermal insulation inner layer 13. The caulking strip 4 includes a decorative layer and a thermal insulation layer. The thermal insulation layer is provided with a connecting groove for accommodating the reinforcing rod 32. The width of the connecting groove is smaller than the rod diameter of the reinforcing rod 32. When the reinforcing rod 32 is located in the connecting groove, it is in an interference fit state with the connecting groove. The thermal insulation layer is also provided with a clearance hole 41 for accommodating the fixing column 313. The aperture of the clearance hole 41 is larger than the aperture of the fixing hole 315. In this embodiment, the thermal insulation layer, the thermal insulation outer layer 12 and the thermal insulation inner layer 13 can all be made of polyurethane foam material.

[0031] The present application also discloses a production process for an exterior wall composite insulation board, comprising the following steps: grooving: opening corresponding grooves on an insulation outer layer 12, an insulation inner layer 13 and an insulation layer; gluing: applying glue in the grooves; reinforcing layer connection: installing the elastic layer 2 in the grooves of the insulation outer layer 12, and installing the reinforcing rod 32 in the grooves of the insulation inner layer 13; board layer splicing: connecting the decorative outer layer 11, the insulation outer layer 12, the insulation inner layer 13 and the adhesive layer 14 in sequence; connecting the elastic layer 2: connecting the elastic layer 2 and the connecting plate 31.

[0032] The implementation principle of this embodiment is as follows: during the installation process, an adhesive is applied to the adhesive layer 14, the main board body is placed at a suitable position on the wall, and then the connecting plate 31 is connected to the wall by expansion bolts. In the process of connecting the connecting plate 31 to the wall, the upper board body 311 is forced to move toward the lower board body 312, so that the fixing column 313 extends from the fixing hole 315, and then the anti-slip teeth 314 are moved out of the fixing hole 315 and deformed, thereby fixing the upper board body 311. When the main board body is installed, an adhesive is applied to the corresponding position of the main board body and the corresponding position of the insulation layer of the caulking strip 4, and the caulking strip 4 is installed between adjacent main board bodies to complete the installation. When the caulking strip 4 is installed, the anti-slip teeth 314 are located in the clearance hole 41 and are against the hole wall.

[0033] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
