Description

Technical Field

[0001] This disclosure relates to the field of external wall insulation technology, and in particular to an external wall insulation paving structure. Background Technology

[0002] With increasingly stringent requirements for building energy conservation, external wall insulation systems have been widely used in construction projects. Traditional methods for installing external wall insulation typically include adhesive bonding and anchoring. Adhesive bonding involves directly attaching the insulation board to the exterior wall surface with bonding mortar for fixation. However, when large areas of the exterior wall surface peel off, the insulation board is prone to detaching as well. Anchoring involves adding anchors to the adhesive bonding method, using these anchors to pierce the insulation board for auxiliary fixation. Finally, mortar is applied to the outer surface of the insulation board, and a mesh fabric is laid. However, this method compromises the structural integrity of the insulation board, significantly reducing its lifespan. Furthermore, existing insulation boards are often rectangular in shape with straight edges, resulting in poor interlocking between adjacent boards during splicing, leading to weak connection strength and a high risk of detachment. Utility Model Content

[0003] To solve the above-mentioned technical problems, this disclosure provides an external wall insulation paving structure.

[0004] This disclosure provides an external wall insulation cladding structure, including:

[0005] Anchors are fixedly installed inside the wall and partially exposed outside the wall.

[0006] An adhesive layer is applied to the surface of the wall and covers the anchors;

[0007] An insulation board layer is laid on the adhesive layer. The insulation board layer includes multiple insulation boards that can be assembled with each other. The outer edge of the insulation board forms continuous and matching protrusions and grooves. Two adjacent insulation boards are assembled through the protrusions and grooves.

[0008] A protective layer is provided on the insulation board layer.

[0009] Optionally, the anchor includes an anchor nail and an anchor plate. One end of the anchor nail is inserted into a mounting hole in the wall, and the portion of the anchor nail inserted into the mounting hole is fixed in the mounting hole by adhesive. The other end of the anchor nail is connected to the anchor plate, and the anchor plate is exposed outside the wall.

[0010] Optionally, the anchor includes an anchor body and a pair of elastic barbs disposed on the outer peripheral wall of the anchor body. The elastic barbs can elastically expand in a direction away from the anchor body so that the elastic barbs can engage with the wall of the mounting hole.

[0011] Optionally, the elastic barb includes a barb body and a tip. The barb body is bent, and both ends of the barb body are connected to the anchor body. The tip is located at the bend of the barb body and extends obliquely away from the bottom of the mounting hole.

[0012] Optionally, the anchor plate has a through hole, and the anchor bolt passes through the through hole and is welded to the through hole for fixation.

[0013] Optionally, the outer edge of the anchor plate extends in a wavy shape.

[0014] Optionally, the insulation board has a positioning groove on the side facing the anchor, and the portion of the anchor exposed in the wall can be mated in the positioning groove.

[0015] Optionally, the protective layer includes a three-dimensional composite crack-resistant mesh with a grid structure and a protective mortar layer sprayed onto the three-dimensional composite crack-resistant mesh.

[0016] Optionally, an interface agent layer is also coated between the surface of the wall and the adhesive layer.

[0017] Optionally, the adhesive layer is an adhesive mortar layer.

[0018] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0019] The anchors in this exterior wall insulation cladding structure are fixed inside the wall, with some exposed portions. The insulation board layer is tightly connected to the wall and anchors via an adhesive layer, ensuring a stable installation. One end of the anchor is fixed to the wall, and the other end is bonded to the insulation board. The adhesive bonding method between the anchor and the insulation board prevents punctures, effectively protecting the insulation board's lifespan. Furthermore, the anchors prevent the insulation board from detaching when the exterior wall surface peels off, significantly improving the connection strength between the exterior wall and the insulation board. Moreover, the insulation board layer comprises multiple interlocking boards, with continuous, matching protrusions and grooves along the outer edge of each board. This strengthens the interlocking of adjacent boards, resulting in a strong connection and minimal gaps between the boards. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0030] The external wall insulation installation structure of this embodiment includes anchors 1, an adhesive layer, an insulation board layer, and a protective layer. Anchors 1 are fixedly installed within the wall, with a portion exposed above the wall. Specifically, mounting holes are first opened in the wall, and anchors 1 are fixedly installed within these holes. The adhesive layer is applied to the surface of the wall, covering the anchors 1, specifically the portion of the anchors 1 exposed above the wall. The insulation board layer is laid on the adhesive layer and fixed to the wall surface by the adhesive layer. The insulation board layer includes multiple interlocking insulation boards 2, with continuous and matching protrusions 21 and grooves 22 along the outer edges of the insulation boards 2. Figure 1As shown, in this embodiment, the protruding part 21 is a square protrusion protruding outward relative to the insulation board 2. Adaptively, the slot part 22 is also a square groove recessed inward relative to the insulation board 2. In this embodiment, the protruding part 21 and the slot part 22 are periodically and continuously arranged, and two adjacent insulation boards 2 can be assembled through the protruding part 21 and the slot part 22. In this embodiment, the protruding part 21 and the slot part 22 can also be an arc-shaped protrusion or an arc-shaped groove to realize the assembly and connection of two adjacent insulation boards 2. In addition, they can also be other regular or irregular shapes, including but not limited to the square and arc-shaped structures mentioned in this embodiment. The protective layer is disposed on the insulation board layer, specifically on the side of the insulation board layer away from the wall. It can be tightly bonded to the insulation board layer to form an integrated protective layer to protect the insulation board layer.

[0031] In this embodiment, the anchor 1 of the external wall insulation paving structure is fixedly installed inside the wall, with a portion of the anchor 1 exposed outside the wall. The insulation board layer is tightly connected to the wall and the anchor 1 through an adhesive layer, so that the insulation board layer can be stably installed on the wall. One end of the anchor 1 is fixedly connected to the wall, and the other end is bonded to the insulation board layer. In this embodiment, the anchor 1 and the insulation board layer are bonded together without puncturing the insulation board layer, which can effectively ensure the service life of the insulation board layer. Moreover, when the outer surface of the wall falls off, the anchor 1 can effectively prevent the insulation board layer from falling off. Compared with the traditional adhesive method, the addition of the anchor 1 can effectively improve the connection strength between the external wall and the insulation board layer. Furthermore, the insulation board layer of the external wall insulation paving structure includes multiple insulation boards 2 that can be assembled with each other. The outer edge of the insulation board 2 is provided with continuous and matching protrusions 21 and grooves 22, which can effectively strengthen the interlocking of two adjacent insulation boards 2, so as to achieve the effect of strong connection strength and small splicing gap.

[0032] Optionally, such as Figure 2 and Figure 3 As shown, the anchor 1 in this embodiment includes two parts: an anchor 11 and an anchor plate 12. One end of the anchor 11 is inserted into a mounting hole in the wall, and the portion of the anchor 11 inserted into the mounting hole is fixed in the mounting hole by adhesive bonding. Optionally, high-strength epoxy resin adhesive can be injected into the hole to bond and fix the portion of the anchor 11 inserted into the mounting hole. The other end of the anchor 11 is connected to the anchor plate 12, and the anchor plate 12 is exposed in the wall and bonded to the insulation board 2 by an adhesive layer.

[0033] Furthermore, such as Figure 2As shown, the anchor 11 includes an anchor body 111 and a pair of elastic barbs 112 disposed on the outer peripheral wall of the anchor body 111. The elastic barbs 112 can be a filament structure or a sheet structure, and are made of elastic material. The elastic barbs 112 can elastically expand in a direction away from the anchor body 111. It can be understood that the elastic barbs 112 can be subjected to radial compression deformation. After the mounting hole in the wall is opened, before inserting the anchor 11 into the mounting hole, the operator first holds and lightly presses the elastic barb 112 part to deform the elastic barb 112 under pressure so that it gets as close as possible to the anchor body 111. Then the anchor 11 is inserted into the mounting hole. Due to the release of external force, the elastic barbs 112 elastically expand in the mounting hole in a direction away from the anchor body 111. Since the inner wall of the wall mounting hole is not a smooth wall surface, the elastic barbs 112 can engage with the hole wall of the mounting hole. At this point, the anchor body 111 can be gently pulled outward to allow the elastic barb 112 to reach its optimal expansion state. It is understood that since the elastic barb 112 is already engaged with the hole wall after the anchor 11 is inserted into the mounting hole, gently pulling the anchor body 111 outward will further extend the elastic barb 112 radially, allowing it to engage more tightly with the hole wall. After the anchor 11 is installed, high-strength epoxy resin is injected into the mounting hole in the wall to further secure the anchor 11 within the hole.

[0034] Furthermore, such as Figure 1 As shown, the elastic barb 112 in this embodiment includes a barb body 1121 and a barb tip 1122. The barb body 1121 is bent, and both ends of the barb body 1121 are connected to the anchor body 111. The barb body 1121 and the anchor body 111 form a triangular structure. The barb tip 1122 is located at the bend of the barb body 1121 and extends obliquely away from the bottom of the mounting hole. The barb tip 1122 can be inserted into the wall of the mounting hole. The bend of the barb body 1121 provides a deformation basis for the radial expansion of the barb body 1121.

[0035] Optionally, such as Figure 3 As shown, in this embodiment, the anchor plate 12 has a through hole 121, through which the anchor bolt 11 passes and is welded to the through hole 121. Preferably, in this embodiment, the anchor bolt 11 and the through hole 121 can be connected using a high-frequency welding process. In this embodiment, after the anchor bolt 11 is assembled with the mounting hole in the wall, the anchor plate 12 can be fitted onto the anchor bolt 11, and then high-frequency welding can be used to fix the anchor plate 12 onto the anchor bolt 11. Alternatively, the anchor plate 12 can be welded to the anchor bolt 11 before the anchor bolt 11 is inserted into the mounting hole, depending on the actual situation.

[0036] Furthermore, such as Figure 3As shown, the outer edge of the anchor plate 12 in this embodiment extends in a wavy shape to maximize the contact area between the anchor plate 12 and the insulation board 2, increase the connection strength between the anchor plate 12 and the insulation board 2, and effectively distribute the stress.

[0037] Optionally, to further enhance the connection strength between the anchor 1 and the insulation board 2, this embodiment may also provide a positioning groove on the side of the insulation board 2 facing the anchor 1. The anchor 1 includes an anchor 11 and an anchor plate 12. The shape of the positioning groove is adapted to the shape of the anchor plate 12, so that the anchor plate 12, which is coated with an adhesive layer and exposed on the wall, can be inserted into the positioning groove, thereby enhancing the connection strength between the anchor 1 and the insulation board 2. It is understood that the positioning groove in this embodiment is already provided when the insulation board 2 leaves the factory. The relevant processes have been completed on the outer surface of the positioning groove during the design and processing stage, so it will not affect the service life of the insulation board 2.

[0038] Optionally, the protective layer in this embodiment includes a three-dimensional composite crack-resistant mesh with a grid structure and a protective mortar layer sprayed onto the three-dimensional composite crack-resistant mesh. The three-dimensional composite crack-resistant mesh is a three-dimensional mesh structure woven from high-strength polyester fibers and alkali-resistant glass fibers. Compared with traditional two-dimensional alkali-resistant glass fiber mesh, it has stronger crack resistance and stress dispersion capabilities. In this embodiment, a spraying process is used to spray the protective mortar layer onto the three-dimensional composite crack-resistant mesh. The spraying process can achieve uniform thickness, avoid the problems of hollowness and wrinkles caused by manual laying of mesh, improve construction efficiency by 50%, and significantly improve the impact resistance and crack resistance of the protective layer. It can more effectively prevent the insulation board 2 from being eroded and damaged by the external environment, while improving the flatness and durability of the surface of the insulation board 2.

[0039] Optionally, in this embodiment, an interface agent layer is also coated between the surface of the wall and the adhesive layer. It is understood that in this embodiment, the wall surface is pretreated before the adhesive layer is applied, that is, an interface agent is first applied to the surface of the wall, which can improve the adhesion of subsequent processes.

[0040] Optionally, the adhesive layer in this embodiment is an adhesive mortar layer, specifically an adhesive mortar specifically for the insulation board 2, so as to fix the insulation board 2 to the surface of the wall.

[0041] The specific implementation method of the external wall insulation paving structure in this embodiment is as follows:

[0042] First, installation holes are pre-drilled in the wall. Special anchors 11 with elastic barbs 112 are inserted into these holes. The elastic barbs 112 expand outwards within the holes and mechanically interlock with the inner wall. High-strength epoxy resin is then injected into the holes, chemically bonding the anchors 11 to the wall. This dual action ensures a secure anchoring. The anchors 11 and the wall utilize a composite system of mechanical locking and chemical anchoring, forming a high-strength connection. Corrugated anchor plates 12 are connected to the anchors 11 using a high-frequency welding process. Insulation board bonding mortar is then applied to the wall surface, and the anchor plates 12 are also coated simultaneously. The insulation board 2 is then firmly adhered to the wall surface. Finally, an interface treatment agent is sprayed onto the outer surface of the insulation board 2. A three-dimensional composite crack-resistant mesh is then laid flat on the insulation board 2. Polymer-modified cement mortar is evenly sprayed onto the three-dimensional composite crack-resistant mesh using a special spray gun, allowing the mortar to penetrate the mesh pores and bond tightly with the insulation board, forming an integrated protective layer.
