[0047] An embodiment of this application discloses an exterior wall insulation structure and a construction method thereof.

[0048] It should be noted that in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0049] In a first aspect, the present application provides a thermal insulation structure for building exterior walls:

[0050] Referring to Figure 1 、 Figure 2 and Figure 3 , a thermal insulation structure for building exterior walls includes a connecting base 1, a thermal insulation board 3, and a connecting mechanism 4. The connecting base 1 is connected to the wall surface, and the thermal insulation board 3 is connected to the connecting base 1 through the connecting mechanism 4. During the installation process, on-site workers only need to first embed or install the connecting base 1 in the wall body, and then splice the thermal insulation board 3 onto the connecting base 1. Moreover, due to the setting of the connecting mechanism 4, rapid docking and installation can be achieved. And when the thermal insulation board 3 needs to be repaired, only the damaged thermal insulation board 3 needs to be replaced. Therefore, compared with the related technology, both the installation and repair of the present application are more convenient, thus solving to a certain extent the problem in the related technology of how to facilitate the installation and repair while ensuring the thermal insulation effect of the new building exterior wall.

[0051] Specifically, the connecting base 1 is fixedly connected to the exterior wall surface, and multiple connecting bases 1 are provided on one building wall body 2. It should be noted that the building wall body 2 referred to here can be a structural wall or a masonry wall.

[0052] Furthermore, regarding the fixing method of the connecting base 1, it can be embedded in the building wall body 2, or it can also be installed on the building wall body 2 later. If it is installed on the building wall body 2 later, a groove for later installing the connecting base 1 needs to be reserved and opened on the building wall body 2, and after installation, adhesives or other building materials can be used for connection.

[0053] Specifically, the thermal insulation board 3 is used for the thermal insulation of the building exterior wall. The thermal insulation board 3 is detachably connected to the connecting base 1. Multiple thermal insulation boards 3 are provided on one building wall body 2, and one thermal insulation board 3 is connected to two connecting bases 1. That is, the exterior wall on one building wall body 2 is jointly spliced and combined by multiple connecting bases 1 and multiple thermal insulation boards 3, thus effectively improving the construction efficiency of the entire exterior wall.

[0054] Furthermore, regarding the thermal insulation board 3 of the present application,

[0055] Reference Figure 4 The insulation board 3 includes a base layer 31, a heat insulation layer 32, an alkali-resistant layer 33 and a plastering layer 34. The base layer 31, the heat insulation layer 32, the alkali-resistant layer 33 and the plastering layer 34 are arranged in sequence. The connecting plate 41 is located on the base layer 31, and the hole passes through the base layer 31, the heat insulation layer 32, the alkali-resistant layer 33 and the plastering layer 34.

[0056] In the embodiment of the present application, the heat insulation layer 32 is made of expanded polystyrene layer. In other embodiments, the heat insulation layer 32 can also be made of extruded polystyrene, polyurethane foam, rock wool, glass wool, expanded protein particles and other materials, which are also preferred embodiments of the present application. The alkali-resistant layer 33 is made of polymer-modified gypsum. In other embodiments, it can also be made of materials such as alkaline sealants and alkali-resistant adhesives, which are also preferred embodiments of the present application.

[0057] Meanwhile, it should be noted that the base layer 31 and the heat insulation layer 32 are bonded together using an adhesive.

[0058] As for the specific manufacturing process of the insulation board 3, the insulation board 3 in the embodiment of the present application is prefabricated in the factory according to the factory requirements. As for the manufacturing process, the embodiment of the present application does not make a specific description. The setting and prefabrication of the insulation board 3 in the present application is more green and environmentally friendly compared with the related art, which uses a lot of manpower and material resources to apply or attach on site.

[0059] As for the multi-layer structure of the insulation board 3 itself, the insulation board 3 not only has the ability to keep warm, but also has a certain strength and can also play an alkali-resistant role to reduce the possibility of corrosion damage to metal parts such as the connecting base 1, the connecting nut 43 and the connecting screw 42.

[0060] Further, see Figure 5 An anchor bolt 35 is also provided inside the insulation board 3 , and the anchor bolt 35 passes through the insulation layer 32 toward the base layer 31 and is fixed on the base layer 31 .

[0061] The provision of the anchor bolts 35 enables the heat insulation layer 32 to be better fixed on the base layer 31 , further improving the stability of the heat insulation board 3 .

[0062] Specifically, refer to Figure 6 and Figure 7, the connecting mechanism 4 is used for connecting the base 1 and the heat preservation board 3. The connecting mechanism 4 includes a connecting plate 41, a connecting screw 42, a connecting nut 43 and a quick-connecting component 44. The connecting plate 41 is fixedly connected to the heat preservation board 3. A connecting hole is formed in the connecting base 1. The connecting plate 41 can be inserted into the connecting hole. The connecting screw 42 is slidably connected to the connecting base 1. A relief hole is formed in the heat preservation board 3. The connecting screw 42 can pass through the relief hole. The connecting nut 43 is threadedly connected to the connecting screw 42. The quick-connecting component 44 is located in the connecting base 1. The quick-connecting component 44 is used to drive the connecting screw 42 to slide on the connecting base 1 when the connecting plate 41 enters the connecting hole. It should be noted that in the embodiments of the present application, the connecting hole and the relief hole are not specifically marked and shown in the drawings of the embodiments of the present application.

[0063] In the embodiments of the present application, after the connecting base 1 and the heat preservation board 3 are connected, the connecting screw 42 and the connecting nut 43 are finally used for connection. In other embodiments, welding or other mechanical connection methods can also be used, which are also the embodiments that the present application can implement.

[0064] The connecting mechanism 4 is set as a combination of the connecting plate 41, the connecting screw 42, the connecting nut 43 and the quick-connecting component 44. During installation, only the connecting plate 41 needs to be inserted into the connecting hole. Under the action of the quick-connecting component 44, the connecting screw 42 can pass through the connecting base 1, so that the staff can use the connecting nut 43 to connect the connecting screw 42, thereby completing the installation of the heat preservation board 3.

[0065] Further, the quick-connecting component 44 includes a contact plate 441, a transmission group 442, a lifting group 443 and a lifting seat 444. An activity groove is formed in the connecting base 1. A slide rail is fixedly connected to the inner side wall of the activity groove. The contact plate 441 can slide on the slide rail. The contact plate 441 is fixedly connected to the transmission group 442. The transmission group 442 is movably connected to the lifting group 443. The lifting group 443 is fixedly connected to the lifting seat 444. The lifting seat 444 is slidably connected to the inner bottom wall of the activity groove. The connecting screw 42 is fixedly connected to one end of the lifting seat 444 away from the lifting group 443.

[0066] During the installation process, when the connecting plate 41 abuts against the abutting plate 441, the abutting plate 441 will slide along the slide rail in the movable groove under the action of an external force, thereby driving the movement of the transmission group 442. The movement of the transmission group 442 will drive the movement of the lifting group 443, and finally lift the lifting seat 444 upward, so that the connecting screw 42 penetrates through the connecting base 1. The quick-connecting component 44 is set as a combination of the abutting plate 441, the transmission group 442, the lifting group 443 and the lifting seat 444, so that when installing the insulation board 3, it can be better positioned and installed. It should be noted here that regarding how the abutting plate 441 slides on the slide rail, the present application provides an implementable solution, that is, a groove is opened on the slide rail, and a matching block is fixedly arranged on the abutting plate 441, and the block can be made to slide in the groove. This is well-known to those skilled in the art, so it will not be elaborated too much in the embodiments of the present application.

[0067] Furthermore, for the convenience of disassembly and repair, a reset member 5 is also provided. One end of the reset member 5 is fixedly connected to the bottom wall of the movable groove, and the other end is fixedly connected to the abutting plate 441. In the embodiment of the present application, the reset member 5 is a compression spring. In other embodiments, the reset member 5 can also be set as a tension spring, elastic rubber, etc. These are all preferred embodiments of the present application, but only the position of the reset member 5 needs to be changed accordingly.

[0068] When the insulation board 3 needs to be repaired, due to the setting of the reset member 5, the on-site staff only needs to remove the connection nut 43 and the connecting screw 42, and the reset member 5 can generate a reaction force on the abutting plate 441, and then can have a force on the connecting plate 41 away from the connecting base 1, making it more labor-saving for the staff to repair and replace, and thus improving the repair efficiency.

[0069] Furthermore, the transmission group 442 includes a first gear 4421, a second gear 4422, a first rack 4423 and a second rack 4424. The first gear 4421 is rotatably connected to the inner bottom wall of the movable groove, the second gear 4422 is coaxially arranged with the first gear 4421, the first rack 4423 is fixedly connected to the abutting plate 441, the first rack 4423 meshes with the first gear 4421, the second rack is slidably connected to the inner bottom wall of the movable groove, the second gear 4422 meshes with the second rack, one end of the second rack is slidably connected to the lifting group 443, and the first rack 4423 and the second rack are perpendicular to each other.

[0070] It should be noted that regarding how the second rack slides on the inner bottom wall of the movable groove, in the embodiment of the present application, a sliding groove for facilitating the sliding of the second rack can be opened on the inner bottom wall of the movable groove. This is well-known to those skilled in the art, and only for the convenience of expression, it is not specifically shown in the drawings of the embodiments of the present application.

[0071] When the abutment plate 441 is subjected to pressure from the connecting plate 41, the movement of the abutment plate 441 drives the first rack 4423 to move, and the movement of the first rack 4423 drives the first gear 4421 to rotate, thereby driving the coaxially arranged second gear 4422 to rotate, and the rotation of the second gear 4422 drives the movement of the second rack, and the other end of the second rack drives the lifting group 443 to move, and finally drives the connecting screw 42 to protrude upward to the connecting base 1, thereby realizing the lifting of the connecting screw 42 so that it can be connected with the connecting nut 43 later.

[0072] Furthermore, the lifting group 443 includes a lifting gear 4431 and a lifting rack 4432. The lifting gear 4431 is rotatably connected to the inner bottom wall of the movable groove, the lifting rack 4432 is fixedly connected to the lifting seat 444, the lifting rack 4432 is meshed with the lifting gear 4431, and the lifting gear 4431 is meshed with the second rack. It should be noted that in the embodiment of the present application, since the lifting gear 4431 is meshed with the second rack 4424 and the lifting rack 4432 at the same time, and a certain concession setting needs to be made for the lifting rack 4432 and the second rack 4424, the width of the lifting gear 4431 is at least greater than the sum of the widths of the second rack and the lifting rack 4432.

[0073] The lifting group 443 is configured as a combination of a lifting gear 4431 and a lifting rack 4432 , so that the second rack drives the lifting gear 4431 to rotate, and the lifting gear 4431 drives the lifting rack 4432 to move, thereby achieving the lifting of the connecting screw 42 .

[0074] In order to make the lifting process more stable, in the embodiment of the present application, a plurality of lifting gears 4431 are provided, a plurality of lifting racks 4432 are provided, and the plurality of lifting gears 4431 correspond one to one with the plurality of lifting racks 4432. Specifically, the present application has two lifting gears 4431 and two lifting racks 4432. In other embodiments, the lifting gears 4431 can also be provided as one, three, or other numbers of multiples, which are all embodiments that can be implemented in the present application.

[0075] The above arrangement further improves the stability during the lifting process to ensure that the connecting screw 42 can pass through the connecting base 1 and the insulation board 3.

[0076] The implementation principle of a building exterior wall insulation structure in an embodiment of the present application is as follows: the building exterior wall insulation structure of the present application is arranged as a combination of a connecting base 1, an insulation board 3 and a connecting mechanism 4, so that when the building exterior wall insulation structure is to be constructed and installed, a split and modular installation can be carried out. First, the connecting base 1 is installed, and then the insulation board 3 is installed piece by piece. Compared with the insulation board 3 in the related art, the present application ensures the insulation performance of the insulation board 3 while being more convenient for maintenance. During maintenance, it is only necessary to directly replace the plate that needs to be repaired. Moreover, due to the setting of the connecting mechanism 4, both installation and replacement are more convenient, thereby solving to a certain extent the problem of how the new building exterior wall in the related art can ensure its insulation effect while being easy to install and repair.
