[0002] The exterior wall insulation layer refers to a building layer that is constructed by processing insulation materials into an insulation structure and then fixing the insulation structure one by one to the exterior surface of the wall. It can reduce the efficiency of heat exchange between the building and the external environment, increase the thermal stability of the building, and also prevent wind, frost, rain and snow from wetting the exterior wall to a certain extent, thus improving the moisture resistance of the wall and avoiding phenomena such as mold, condensation and cold penetration inside the building.

[0003] Currently, more and more buildings are using thermal insulation structures. However, due to their structural design, the current thermal insulation structures are relatively complicated to install, time-consuming and labor-intensive. Furthermore, repairing the external wall insulation layer after damage is also a challenge, especially in high-altitude working environments, which undoubtedly poses significant safety risks to installation and maintenance personnel.

[0004] Therefore, a non-destructive repair method for external wall insulation layers and an external wall insulation structure are proposed to address the above problems. Summary of the Invention

The top plates in the same card plate are fixed together by a first rod. The first rod is located below the other end of the top plate and is located on the upper surface of the horizontal part of the card plate. The other end of the top plate is fixed together by a second rod, which is also located on the upper horizontal surface of the card plate.

[0010] Preferably, the lower surface of the top plate is provided with a shovel plate, which is located on the lower surface of the horizontal part of the clamping plate, and the shovel plate and the top plate are clamped in a rectangular opening.

[0011] Preferably, each of the insert rods has a plate fixed to its lower end, and the plate has a connecting hole inside the insulation wall. The surface of the insulation wall has multiple fixing holes, each of which extends to the point where the insert rod and the insulation wall overlap, and each fixing hole is set in the same hole as the connecting hole.

[0012] Preferably, each of the insulated walls has connecting grooves on both sides, the connecting grooves are set along the height direction of the insulated wall, and connecting strips are inserted in the connecting grooves. When two adjacent insulated walls are assembled and connected, the connecting strips are inserted into the connecting grooves.

[0013] Preferably, one end of the connecting strip is provided with a casting hole, and multiple overflow holes are provided on the surface of the connecting strip. Moreover, the diameter of the overflow holes on the same connecting strip that are closer to the upper end of the connecting strip is larger than the diameter of the overflow holes that are farther away from the upper end of the connecting strip.

[0014] A non-destructive repair method for exterior wall insulation layers, applicable to any of the aforementioned exterior wall insulation structures, comprising the following steps:

[0015] S1: The external wall insulation layer is any one of the external wall insulation structures in claims 1-8. If the external wall insulation layer is found to be cracked, and the external wall insulation layer is not loose, it is only necessary to open the external wall insulation layer, add crack-resistant mortar and mesh cloth, and the mesh cloth should overlap more than 5 cm on both sides to complete the repair.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Reference Figures 1-6 An external wall insulation structure includes an insulated wall 1 and an installation assembly; the installation assembly includes a vertical plate 2, a hook plate 3 on one side wall of the vertical plate 2, and a clamping plate 4 at the upper end of the vertical plate 2. The clamping plate 4 is V-shaped and is embedded in a strip groove opened in the building insulation wall 1; a strip-shaped slot 5 is opened on the inner side wall at the upper end of the insulation wall 1, the slot 5 is opened along the width direction of the insulation wall 1, and a strip-shaped protrusion 6 is provided in the slot 5; the protrusion 6 is fastened in the hook plate 3;

[0038] In this embodiment, a convenient-to-install external wall insulation structure is provided. First, the layout of the insulation wall 1 to be installed on the wall is planned. The drilling positions on the wall are measured on the drawing, and the positions of the strip grooves on the wall are also measured. Then, the installation components are fixed on the wall. Specifically, the clip plate 4 is embedded in the strip groove on the wall, and the vertical plate 2 is fixed on the wall with bolts. Then, the insulation wall 1 is installed. The clip 5 is aligned with the hook plate 3, and the protrusion 6 is embedded in the hook plate 3. The left and right positions between the insulation wall 1 and the vertical plate 2 are adjusted. Finally, bolts are used to pass through the insulation wall 1 and the vertical plate 2 to fix the insulation wall 1 on the wall.

[0039] The design of this external wall insulation structure facilitates the installation of the insulation wall 1. The pre-installed installation components provide an installation point for the insulation wall 1, which supports the insulation wall 1. When faced with the heavy insulation wall 1, it can help the installer to install the insulation wall 1 easily and smoothly, reduce labor and reduce the safety risks of working at height.

[0040] Reference Figures 1-7The upper surface of the insulated wall 1 has multiple evenly spaced insertion holes 7, each insertion hole 7 penetrating the protrusion 6. The lower end of the insulated wall 1 is provided with an insertion rod 8. The inner surface of the hook plate 3 has multiple through holes 9, with the protrusion 6 fitting into the latch 5. The insertion holes 7 and through holes 9 are coaxially aligned. When two adjacent insulated wall 1s are assembled, the insertion rod 8 on the upper insulated wall 1 is inserted into the insertion hole 7 on the lower insulated wall 1. To improve the overall integrity and stability of the external wall insulation structure, the following is provided: The design of the insertion rod 8 and the insertion hole 7 allows for the insertion of the insertion rod 8 on the upper insulation wall 1 into the insertion hole 7 on the lower insulation wall 1 when two adjacent insulation walls 1 are installed. When installing the insulation wall 1, the lower insulation wall 1 is installed first, and the upper insulation wall 1 is installed from the lower one. This is to facilitate the sequential installation of the insulation wall 1. At the same time, the lower insulation wall 1, which has already been installed and fixed, can provide a pre-support force for the upper insulation wall 1 that is to be fixed, which also makes it easier for the operator to work.

[0041] Reference Figures 3-6 A strip-shaped notch 10 is provided on the lower inner sidewall of the thermal insulation wall 1, and the notch 10 is set along the width direction of the thermal insulation wall 1; a top plate 11 is provided inside the clamping plate 4, one end of the top plate 11 rests in the notch 10, and the other end of the top plate 11 rests on the inner sidewall of the upper plate of the clamping plate 4; the clamping plate 4 is embedded in the strip groove on the wall. The shape of the clamping plate 4 allows it to be easily embedded in the strip groove, but it is difficult to remove the clamping plate 4 from the strip groove. At the same time, during the process of the upper thermal insulation wall 1 being installed on the lower thermal insulation wall 1, the surface of the upper thermal insulation wall 1 presses against the top plate 11, pushing the top plate 11 deeper into the clamping plate 4. At the same time, the top plate 11 presses against the clamping plate 4, at which time the clamping plate 4 is in an expanding trend, providing stability for the clamping plate 4 embedded in the strip groove, and also improving the firmness of the external wall insulation structure.

[0042] Reference Figure 2 The horizontal surface of the card plate 4 has multiple rectangular openings 12, and a top plate 11 is horizontally slidably connected within each rectangular opening 12. The top plates 11 within the same card plate 4 are fixed together by a first rod 13. The first rod 13 is located below the other end of the top plate 11 and is located on the upper surface of the horizontal part of the card plate 4. The other end of the top plate 11 is fixed together by a second rod 14, which is also located on the upper horizontal surface of the card plate 4. The top plates 11 are supported on the upper horizontal surface of the card plate 4 by the first rod 13 and the second rod 14, and multiple top plates 11 are fixed into a whole. At the same time, the top plates 11 are restricted to move within the rectangular openings 12, which restricts the direction of movement of the top plates 11, so that the top plates 11 effectively squeeze the card plate 4, squeeze and expand the card plate 4, and improve the firmness between the card plate 4 and the wall.

[0043] Reference Figure 2 and Figure 4 ,as well as Figure 8The lower surface of the top plate 11 is provided with a shovel plate 15, which is located on the lower surface of the horizontal part of the clamping plate 4. The shovel plate 15 and the top plate 11 are clamped in the rectangular opening 12. The end of the shovel plate 15 is wedge-shaped. During the process of inserting the shovel plate 15 into the strip groove, the lower surface of the shovel plate 15 presses against the bottom horizontal surface of the strip groove and pushes against the clamping plate 4, so that the clamping plate 4 presses against the top horizontal surface of the strip groove. This is also a measure to improve the stability of the clamping plate 4 embedded in the strip groove.

[0044] Reference Figures 5-6 Each of the insert rods 8 has a plate 16 fixed to its lower end. The plate 16 has a connecting hole 17 inside the insulation wall 1. The surface of the insulation wall 1 has multiple fixing holes 18, each of which extends to the overlapping part of the plate 16 and the insulation wall 1. Each fixing hole 18 is set in the same hole as the connecting hole 17. When two adjacent insulation walls 1 are spliced, the plate 16 is inserted into the insulation wall 1 along the insert hole 7. Then, a bolt is used to fix the two adjacent insulation walls together by passing through the fixing hole 18 of the insulation wall 1 into the connecting hole 17 on the plate 16. At the same time, the bolt passes through the vertical plate 2 and is fixed to the wall. The bolt can fix the insulation wall 1 to the wall and also connect and fix the two insulation walls 1 together, further improving the connection between the two insulation walls 1.

[0045] Reference Figures 10-12 Each of the insulated wall panels 1 has connecting grooves 19 on both sides, which are set along the height of the insulated wall panel 1. Connecting strips 21 are inserted into the connecting grooves 19. When two adjacent insulated wall panels 1 are assembled and connected, the connecting strips 21 are inserted into the connecting grooves 19. In order to further improve the integrity between the insulated wall panels 1, connecting grooves 19 and connecting strips 21 are set to connect two adjacent insulated wall panels 1. After the two adjacent insulated wall panels 1 are installed, the connecting strips 21 are inserted into the connecting grooves 19. The connecting strips 21 connect the two insulated wall panels 1 together, thereby improving the stability of the external wall insulation structure.

[0046] Reference Figure 12 One end of the connecting strip 21 is provided with a pouring hole 22, and multiple overflow holes 23 are provided on the surface of the connecting strip 21. The diameter of the overflow holes 23 on the same connecting strip 21 is larger than that of the overflow holes 23 further away from the upper end of the connecting strip 21. After the thermal insulation wall 1 at the same horizontal height is installed, the connecting strip 21 is embedded into the connecting groove 19, and then glue is injected into the pouring hole 22. Water is added and flows out along the overflow port to fill the gap between the connecting strip 21 and the connecting groove 19. After the glue solidifies, the connecting strip 21 is bonded to the thermal insulation wall 1 to improve the overall integrity of the external wall insulation structure. At the same time, the setting of the diameter of the overflow hole 23 allows the glue to flow out from each overflow hole 23 to repeatedly fill the gap.

[0047] Reference Figure 13 A non-destructive repair method for an external wall insulation layer, applicable to the aforementioned external wall insulation structure, comprising the following steps:

[0048] S1: The external wall insulation layer is any one of the external wall insulation structures in claims 1-8. If the external wall insulation layer is found to be cracked, and the external wall insulation layer is not loose, it is only necessary to open the external wall insulation layer, add crack-resistant mortar and mesh cloth, and the mesh cloth should overlap more than 5 cm on both sides to complete the repair.

[0049] S2: If the external wall insulation layer is severely cracked and cannot be filled and reinforced with mesh cloth, directly remove the damaged external wall insulation layer, replace it with a new external wall insulation layer, remove the aged fixing adhesive, and scrape off the damaged external wall insulation layer.

[0050] S3: Clean the wall surface, use a knife to remove the residual adhesive adhering to the wall surface, wash it with clean water, wipe it clean, apply new fixing adhesive, and finally install the new external wall insulation layer.

[0051] Reference Figure 13 After the new exterior wall insulation layer in S3 is installed, press it firmly for 2-5 minutes, and at the same time use an open flame to heat the glue that has overflowed between the exterior wall insulation layer and the wall.

[0052] Working principle: In this embodiment, a convenient external wall insulation structure is provided. First, the layout of the insulation wall 1 to be installed on the wall is planned. The drilling positions on the wall are measured on the drawing, and the position of the strip groove on the wall is also measured. Then, the installation components are fixed on the wall. Specifically, the clip plate 4 is embedded in the strip groove on the wall, and the vertical plate 2 is fixed on the wall with bolts. Then, the insulation wall 1 is installed. The clip 5 is aligned with the hook plate 3, and the protrusion 6 is embedded in the hook plate 3. The left and right positions between the insulation wall 1 and the vertical plate 2 are adjusted. Finally, bolts are used to pass through the insulation wall 1 and the vertical plate 2 to fix the insulation wall 1 on the wall.

[0053] The design of this external wall insulation structure facilitates the installation of the insulation wall 1. The pre-installed installation components provide an installation point for the insulation wall 1, and the air duct supports the insulation wall 1. When faced with the heavy insulation wall 1, it can help the installer to install the insulation wall 1 easily and smoothly, reduce labor and reduce the safety risks of working at height.

[0054] To improve the overall integrity and stability of the external wall insulation structure, a structural design of insert rod 8 and insertion hole 7 is provided. For two adjacent insulation walls 1, the insert rod 8 on the upper insulation wall 1 is inserted into the insertion hole 7 on the lower insulation wall 1. When installing the insulation wall 1, the lower insulation wall 1 is installed first, and the upper insulation wall 1 is installed from the lower. This is to facilitate the sequential installation of the insulation wall 1. At the same time, the lower insulation wall 1 that has been installed and fixed can provide a pre-support force for the upper insulation wall 1 that is to be fixed, which also facilitates the work of the installer.

[0055] The card plate 4 is embedded in the strip groove on the wall. The shape of the card plate 4 makes it easy to embed into the strip groove, but the card plate 4 is difficult to remove from the strip groove. At the same time, during the process of the upper insulation wall 1 being installed on the lower insulation wall 1, the surface of the upper insulation wall 1 presses against the top plate 11, pushing the top plate 11 towards the depth of the card plate 4. At the same time, the top plate 11 presses against the card plate 4. At this time, the card plate 4 is in an expanding trend, which provides stability for the card plate 4 embedded in the strip groove and also improves the firmness of the external wall insulation structure.

[0056] The top plate 11 is mounted on the horizontal upper surface of the card plate 4 by the first rod 13 and the second rod 14, and multiple top plates 11 are fixed into a whole. At the same time, the top plate 11 is restricted to move within the rectangular opening 12, which restricts the movement direction of the top plate 11, so that the top plate 11 can effectively squeeze the card plate 4, squeeze and expand the card plate 4, and improve the firmness between the card plate 4 and the wall.

[0057] The end of the shovel plate 15 is wedge-shaped. During the process of inserting the shovel plate 15 into the strip groove, the lower surface of the shovel plate 15 presses against the bottom horizontal surface of the strip groove and pushes against the clamping plate 4, so that the clamping plate 4 presses against the top horizontal surface of the strip groove. This is also a measure to improve the stability of the clamping plate 4 embedded in the strip groove.

[0058] When two adjacent insulation wall panels 1 are spliced ​​together, the insert plate 16 is inserted into the insulation wall panel 1 along the insertion hole 7. Then, the bolt passes through the fixing hole 18 of the insulation wall panel 1 and into the connecting hole 17 on the insert plate 16 to fix the two adjacent panels together. At the same time, the bolt passes through the vertical plate 2 and is fixed to the wall. The bolt can fix the insulation wall panel 1 to the wall and also connect and fix the two insulation wall panels 1 together, further improving the connection strength between the two insulation wall panels 1.

[0059] To further improve the integrity of the insulation wall 1, a connecting groove 19 and a connecting strip 21 are set to connect two adjacent insulation walls 1 on the left and right sides. After the two adjacent insulation walls 1 are installed, the connecting strip 21 is inserted into the connecting groove 19, connecting the two insulation walls 1 together and improving the stability of the external wall insulation structure. After the insulation walls 1 at the same horizontal height are installed, the connecting strip 21 is embedded into the connecting groove 19, and then glue is injected into the injection hole 22. Water is added and flows out along the overflow hole to fill the gap between the connecting strip 21 and the connecting groove 19. After the glue solidifies, the connecting strip 21 is bonded to the insulation wall 1 to improve the integrity of the external wall insulation structure. At the same time, the diameter of the overflow hole 23 is set so that the glue can flow out from each overflow hole 23 to repeatedly fill the gap.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
