Description

Technical Field

[0001] This utility model relates to the field of building insulation technology, specifically to a moisture-proof and heat-insulating structural layer for building exterior walls. Background Technology

[0002] There are three types of thermal insulation for building exterior walls: external wall insulation, internal wall insulation, and sandwich wall insulation. Internal wall insulation involves bonding insulation material to the inside of the load-bearing wall and then using liquid adhesive to achieve a multi-layer insulation effect. This type of insulation layer has a simple structure, is easy to construct, and has a low cost, making it the most widely used insulation system on the market.

[0003] The structural layers of a building's exterior walls have a significant impact on its thermal insulation and moisture-proof performance. For example, a moisture-proof and thermal insulation structural layer for a building's exterior walls, as disclosed in patent publication number CN220184487U, includes an exterior wall surface. A thermal insulation protective layer is provided on the front side of the exterior wall surface. The thermal insulation protective layer includes a leveling layer, an adhesive layer, an insulation layer, and a crack-resistant layer. A moisture-proof layer is provided on the front side of the thermal insulation protective layer. The moisture-proof layer includes a fireproof layer, a waterproof layer, and a finishing layer. The crack-resistant layer is located on the front side of the insulation layer. The insulation layer is located on the front side of the adhesive layer. The adhesive layer is located on the front side of the leveling layer. The leveling layer is made of mortar. The adhesive layer is made of a special adhesive. The insulation layer is made of expanded polystyrene board. This utility model, through the combined use of an exterior wall surface, a thermal insulation and protective layer, a leveling layer, an adhesive layer, a thermal insulation layer, a crack-resistant layer, a mortar layer, a mesh layer, a moisture-proof layer, a fireproof layer, a waterproof layer, and a finishing layer, can effectively improve the thermal insulation, moisture-proof, and fire-proof performance of the exterior wall surface, and extend its service life.

[0004] Most existing building exterior walls are prefabricated structures, which can be assembled and poured during use. The aforementioned building exterior walls are not suitable for prefabrication. After prefabrication, the required structural layers cannot be freely selected according to the actual environment, resulting in a limited range of applications. Utility Model Content

[0005] The purpose of this utility model is to provide a moisture-proof and heat-insulating structural layer for building exterior walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A moisture-proof and thermal insulation structural layer for building exterior walls includes an exterior wall surface. An anti-crack layer, which is a polymer anti-crack mortar board, is provided on the inner side of the exterior wall surface. A mesh layer is adhered to both sides of the anti-crack layer. An insulation layer, which is a flame-retardant insulation board, is provided on the inner side of the anti-crack layer. A protective layer is provided on the inner side of the insulation layer. The upper surface of the protective layer is coated with a waterproof coating. A first connector is provided between the exterior wall surface and the anti-crack layer. A second connector is provided between the anti-crack layer and the insulation layer. A third connector is provided between the insulation layer and the protective layer. The first, second, and third connectors have identical structures.

[0008] Using the above structure, the exterior wall, crack-resistant layer, insulation layer, and protective layer are fixed and their distances are limited by the first, second, and third connectors. The connection can be completed by pouring concrete into the gaps. The crack-resistant layer has certain tensile properties, which, together with the grid layers on both sides, can improve the structural toughness and crack resistance. The insulation layer can achieve temperature insulation and improve the insulation effect. The protective layer is coated with waterproof paint, which can effectively prevent moisture. Users can also choose whether to need an insulation layer or a protective layer. All are modular designs, and each layer can be prefabricated separately. After prefabrication, users can choose according to their own needs, making it more applicable.

[0009] Preferably, the first connector includes a first connecting rod fixed to the exterior wall surface, the end of the first connecting rod is provided with a first right-angle hook, and the first right-angle hook is inclined downward. A second connecting rod is fixed on the crack-resistant layer, and the end of the second connecting rod is provided with two second right-angle hooks, and the second right-angle hooks are inclined upward. The first right-angle hook is located between the two second right-angle hooks.

[0010] Using the above structure, during installation, a crane is generally used for hoisting. Then, construction workers make minor adjustments to the angle. When connecting, the outer wall surface can be fixed first (side support), and then the crack-resistant layer is lowered. At this time, the first right-angle hook is inserted from above between the two second right-angle hooks, thereby limiting the distance between the outer wall surface and the crack-resistant layer, which facilitates pouring. Similarly, the second and third connectors have the same structure and effect, and will not be described in detail.

[0011] Preferably, the crack-resistant layer has a threaded hole, and a connecting sleeve is threaded into the threaded hole. The end of the connecting sleeve is connected to a plurality of circumferentially distributed inwardly inclined pieces, and the inwardly inclined pieces are inclined inward. The first connecting rod is inserted into the connecting sleeve, and a snap-fit ​​sleeve is threaded to the outside of the connecting sleeve. One end of the snap-fit ​​sleeve is provided with an inner hoop ring, and the inner hoop ring abuts against the inwardly inclined pieces, and the inwardly inclined pieces abut against the first connecting rod.

[0012] Using the above structure, the first connecting rod can be cut to the required spacing during connection. Then, the first connecting rod is inserted into the connecting sleeve, and the snap-fit ​​sleeve is tightened. The inward-curving piece is pressed inward, thereby fixing the first connecting rod through friction. Installation is convenient, and the length of the first connecting rod can be freely cut, which facilitates the adjustment of the distance between the exterior wall and the crack-resistant layer. The connection method of the second connecting rod is the same and will not be described in detail. Similarly, the second and third connecting parts have the same structure and effect and will not be described in detail.

[0013] Preferably, the exterior wall surface, crack-resistant layer and thermal insulation layer are provided with splicing grooves on one side and splicing strips that match the splicing grooves on the other side.

[0014] With the above structure, when in use, the splicing strip is slid in from the top of the splicing groove to connect the two prefabricated components laterally, making the splicing between the building's exterior walls more stable.

[0015] Preferably, a first connecting hook is provided on the outer side of one end of the protective layer, and an extension plate is fixed on the outer side of the other end. A second connecting hook is fixed on the extension plate, and the first connecting hook matches the second connecting hook.

[0016] With the above structure, the protective layer is thinner, and the side grooves will reduce its strength. When the first connecting hook is connected to the second connecting hook of another protective layer, the inner surfaces of the two protective layers are flush and will not damage the waterproof coating on the surface. Moreover, the inner surfaces are flush after pouring, which will not affect subsequent construction.

[0017] Preferably, both the insulation layer and the crack-resistant layer have circular holes.

[0018] With the above structure, during pouring, the poured cement mortar can flow through the round holes between the gaps, improving the pouring effect and preventing voids.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The exterior wall, crack-resistant layer, insulation layer, and protective layer are fixed and their distances are limited by the first, second, and third connectors. The connection is completed by pouring concrete into the gaps. Users can also choose whether to use an insulation layer or a protective layer. All are modular designs, and each layer can be prefabricated separately. After prefabrication, users can choose according to their own needs, making it more applicable.

[0021] Meanwhile, during the connection process, the first connecting rod can be cut to the required spacing, then the first connecting rod is inserted into the connecting sleeve, and the snap-fit ​​sleeve is tightened. The inward-curving piece is then pressed inward, thereby fixing the first connecting rod through friction. This makes installation convenient, and the length of the first connecting rod can be freely cut. Similarly, the second connecting rod can also be freely cut, which facilitates the adjustment of the distance between the exterior wall and the crack-resistant layer. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5As shown, this utility model provides a technical solution: a moisture-proof and heat-insulating structural layer for building exterior walls, including an exterior wall surface 1, an anti-crack layer 2 provided on the inner side of the exterior wall surface 1, the anti-crack layer 2 being a polymer anti-crack mortar board, and a mesh layer 3 pasted on both sides of the anti-crack layer 2, an insulation layer 4 provided on the inner side of the anti-crack layer 2, the insulation layer 4 being a flame-retardant insulation board, a protective layer 5 provided on the inner side of the insulation layer 4, the upper surface of the protective layer 5 being coated with a waterproof coating, and a first connector provided between the exterior wall surface 1 and the anti-crack layer 2, a second connector provided between the anti-crack layer 2 and the insulation layer 4, and a third connector provided between the insulation layer 4 and the protective layer 5, and the first connector, the second connector, and the third connector have the same structure.

[0030] It should be noted that the exterior wall 1, crack-resistant layer 2, insulation layer 4, and protective layer 5 are fixed and their distances are limited by the first, second, and third connectors. The connection can be completed by pouring concrete into the gaps. Moreover, the crack-resistant layer 2 has certain tensile properties, which, together with the grid layers 3 on both sides, can improve the structural toughness and crack resistance. The insulation layer 4 can achieve temperature insulation and improve the insulation effect. The protective layer 5 is coated with waterproof paint, which can effectively prevent moisture. Users can also choose whether to need the insulation layer 4 or the protective layer 5. Both are split designs, and each layer can be prefabricated separately. After prefabrication, users can choose according to their own needs, making it more applicable.

[0031] refer to Figure 4 As shown, the first connector includes a first connecting rod 11 fixed on the outer wall 1. The end of the first connecting rod 11 is provided with a first right-angle hook 12, and the first right-angle hook 12 is inclined downward. A second connecting rod 13 is fixed on the crack-resistant layer 2, and the end of the second connecting rod 13 is provided with two second right-angle hooks 14, and the second right-angle hooks 14 are inclined upward. The first right-angle hook 12 is located between the two second right-angle hooks 14.

[0032] It should be noted that during installation, a crane is generally used for hoisting, and then the construction workers make minor adjustments to the angle. When connecting, the outer wall 1 can be fixed first (side support), and then the crack-resistant layer 2 can be lowered. At this time, the first right-angle hook 12 is inserted from above between the two second right-angle hooks 14, thereby limiting the distance between the outer wall 1 and the crack-resistant layer 2, which facilitates pouring. Similarly, the second and third connectors have the same structure and effect, and will not be described in detail.

[0033] refer to Figure 5As shown, a threaded hole 15 is provided on the crack-resistant layer 2, and a connecting sleeve 16 is threadedly connected to the threaded hole 15. Several circumferentially distributed inwardly inclined pieces 17 are connected to the end of the connecting sleeve 16, and the inwardly inclined pieces 17 are inclined inward. The first connecting rod 11 is inserted into the connecting sleeve 16, and a snap-fit ​​sleeve 18 is threadedly connected to the outside of the connecting sleeve 16. An inner hoop ring 19 is provided at one end of the snap-fit ​​sleeve 18, and the inner hoop ring 19 abuts against the inwardly inclined pieces 17. The inwardly inclined pieces 17 abut against the first connecting rod 11.

[0034] It should be noted that when making the connection, the first connecting rod 11 can be cut according to the required spacing. Then, the first connecting rod 11 is inserted into the connecting sleeve 16, and the snap sleeve 18 is tightened. The inward tilting piece 17 is pressed inward, thereby fixing the first connecting rod 11 through friction. The installation is convenient, and the length of the first connecting rod 11 can be freely cut, which makes it easy to adjust the distance between the outer wall surface 1 and the crack-resistant layer 2. The connection method of the second connecting rod 13 is the same, and will not be described again. Similarly, the second and third connecting pieces have the same structure and effect, and will not be described again.

[0035] refer to Figure 2 As shown, splicing grooves 7 are provided on one side of the exterior wall 1, crack-resistant layer 2 and insulation layer 4, and splicing strips 6 that match the splicing grooves 7 are provided on the other side.

[0036] It should be noted that when using this product, the splicing strip 6 is slid into the splicing groove 7 from above to connect the two prefabricated components laterally, making the splicing between the building's exterior walls more stable.

[0037] refer to Figure 3 As shown, a first connecting hook 8 is provided on the outer side of one end of the protective layer 5, and an extension plate 9 is fixed on the outer side of the other end. A second connecting hook 10 is fixed on the extension plate 9, and the first connecting hook 8 and the second connecting hook 10 are matched.

[0038] It should be noted that the protective layer 5 is relatively thin, and the side groove will reduce its strength. When the first connecting hook 8 is hooked with the second connecting hook 10 of the other protective layer 5, the inner surfaces of the two protective layers 5 are flush and will not damage the waterproof coating on the surface. Moreover, the inner surfaces are flush after pouring, which will not affect subsequent construction.

[0039] Both the insulation layer 4 and the crack-resistant layer 2 have round holes.

[0040] It is important to note that during pouring, the poured cement mortar can flow through the round holes between the gaps, improving the pouring effect and preventing voids.
