Description

Technical Field

[0001] This utility model relates to the field of thermal insulation exterior wall technology for buildings, specifically a crack-resistant thermal insulation exterior wall. Background Technology

[0002] Thermal insulation exterior walls are formed by filling the wall body with thermal insulation mortar, which is made of various lightweight materials as a skeleton and cement as a binder, with additives mixed in. In construction, crack-resistant thermal insulation exterior walls are widely used. However, existing thermal insulation exterior walls have certain problems, namely uneven horizontal and vertical support, which results in poor stability, affects service life, and the insulation effect needs to be improved.

[0003] To address the aforementioned technical issues, CN221663955U, a crack-resistant thermal insulation mortar exterior wall, discloses a method that uses crack-resistant components to improve the strength of the thermal insulation mortar, thereby enhancing its crack resistance and thermal insulation performance. Furthermore, by reinforcing the components, the strength of the thermal insulation mortar is further improved, further enhancing its crack resistance and thermal insulation performance. While this patent does indeed improve the crack resistance, strength, and thermal insulation performance of crack-resistant thermal insulation exterior walls, it still has certain shortcomings. As seen in the attached drawings, to improve crack resistance, the crack-resistant components cannot effectively support lateral and longitudinal forces. Moreover, while filling the entire crack-resistant components with thermal insulation mortar improves thermal insulation performance, it cannot further enhance the overall thermal insulation effect or effectively achieve lateral and longitudinal support, thus shortening the service life.

[0004] Therefore, in order to solve the problems in the prior art and improve the thermal insulation effect while ensuring the crack resistance of the horizontal and vertical support, a crack-resistant thermal insulation exterior wall is proposed to overcome the technical problems in the prior art. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a crack-resistant and heat-insulating exterior wall, which solves the problems that the existing crack-resistant and heat-insulating exterior walls have insufficient support, resulting in poor crack resistance and failing to improve the heat insulation effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crack-resistant and heat-insulating exterior wall, comprising a wall base, a primer layer, a mortar exterior wall layer, a stone-like paint finishing layer, and a stone-like paint intermediate layer. A crack-resistant and heat-insulating structure is provided between the mortar exterior wall layer and the stone-like paint intermediate layer. The crack-resistant and heat-insulating structure includes a curved plate and a central baffle. The curved plate is divided into multiple groups and arranged in a linear array. The central baffle is inserted into the curved plate, and the middle part of the central baffle is a cavity filled with a rock wool filling layer. The crack-resistant and heat-insulating structure between the mortar exterior wall layer and the stone-like paint intermediate layer is filled with heat-insulating mortar to cover the curved plate and the central baffle.

[0007] Furthermore, the curved plate has a groove on its inner side, and the upper and lower surfaces of the middle baffle have protrusions with the same depth as the groove, which cooperate with the groove.

[0008] Furthermore, the upper end of the curved plate has an opening through which the surface of the middle baffle is penetrated. A fixed shaft is inserted into the opening, and a connecting post is inserted into the side of any set of middle baffles to fix the fixed shaft.

[0009] As a preferred technical solution, both the left and right sides of the curved plate are provided with flat surfaces.

[0010] Furthermore, the primer layer is located on the right side, the mortar exterior wall layer is located on the right side of the primer layer, and one side of the mortar exterior wall layer contacts the left side of the curved plate. The right side of the curved plate is provided with a stone-like paint intermediate layer, and the stone-like paint finishing layer is located on the right side of the stone-like paint intermediate layer.

[0011] Compared with the prior art, this utility model provides a crack-resistant and heat-insulating exterior wall with the following beneficial effects:

[0012] 1. This exterior wall, through curved panels, central baffles, fixed shafts, and connecting columns, see reference. Figure 2-6 It is evident that the central baffle can effectively bear the lateral and longitudinal forces borne by the bent plate, thus enabling the overall crack-resistant insulation structure to have good lateral and supporting forces, thereby improving its crack resistance.

[0013] 2. Based on the above, in order to further improve the lateral and longitudinal support, the upper and lower ends of the middle baffle are provided with protrusions, and the corresponding surfaces of the curved plate are provided with grooves, so that the protrusions are stuck in the grooves. This arrangement can further improve the support effect.

[0014] 3. Based on the above, in order to further improve the stability of the curved plate and the middle baffle during installation and thus ensure the subsequent crack resistance effect, through holes are made in the curved plate and the middle baffle. A fixing shaft is inserted into the hole for fixation, and a connecting post is inserted from the side of the middle baffle to the other side to pass through the fixing shaft, thereby further fixing and improving the overall stability.

[0015] 4. This exterior wall utilizes a cavity in the central baffle, filled with rock wool. The cavity itself slows heat transfer by restricting free airflow. Air, as a poor conductor, forms an insulation layer within the cavity, reducing heat conduction and convection. Filling the cavity with rock wool further enhances the insulation effect. The rock wool blocks heat flow through the still air within its fiber structure, while the cavity provides an additional insulation layer. The synergistic effect of these two elements reduces the amount of insulation mortar required and significantly improves living comfort. The cavity provides deformation space for the insulation layer, preventing thermal stress caused by rapid temperature differences from concentrating on the outer surface, thereby reducing the risk of cracking. Structures without cavities are prone to fatigue damage to the insulation layer due to wind pressure, while the cavity disperses the localized force of wind pressure on the wall surface, reducing the occurrence of cracks.

[0023] 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. Example

[0024] Please see Figure 1-6This utility model provides the following technical solution: a crack-resistant and heat-insulating exterior wall, including a wall base 1, a primer layer 2, a mortar exterior wall layer 3, a stone-like paint finishing layer 4, and a stone-like paint intermediate layer 5. A crack-resistant and heat-insulating structure is provided between the mortar exterior wall layer 3 and the stone-like paint intermediate layer 5. The crack-resistant and heat-insulating structure includes a curved plate 6 and a central baffle 7. The curved plate 6 is divided into multiple groups and arranged in a linear array. The central baffle 7 is inserted into the curved plate 6. The central baffle 7 has a cavity in the middle and is filled with a rock wool filling layer 10. The crack-resistant and heat-insulating structure between the mortar exterior wall layer 3 and the stone-like paint intermediate layer 5 is filled with heat-insulating mortar to cover the curved plate 6 and the central baffle 7.

[0025] In this implementation plan, the specific working principle is as follows: Remove loose dust, oil stains, and loose materials from the surface of the wall base 1; repair cracks and holes to ensure the wall base 1 is solid and flat; apply a penetrating, alkali-resistant sealing primer 2 to enhance adhesion and seal the substrate; apply by roller or spray, ensuring even coverage without any missed areas; the dosage is approximately 0.12 kg / m²; before applying the mortar exterior wall layer 3, moisten the primer layer 2 with water (but without standing water), and mechanically stir for 5-6 minutes to ensure even coverage without dry powder lumps; then apply the primer layer 2 in layers, with the first coat ≤10mm thick, the second coat ≤20mm thick, and an interval of ≥24 hours. Construction proceeds from bottom to top and from left to right. The surface is smoothed and compacted with a trowel. The crack-resistant components are then injected with thermal insulation mortar and installed onto the mortar exterior wall layer 3. On the other side, a stone-like paint intermediate layer 5 is sprayed. Finally, the stone-like paint finishing layer 4 is evenly applied onto the stone-like paint intermediate layer 5 and a thin first coat is sprayed, using approximately 1.2 kg / m². After 2 hours of drying, a second coat is applied to adjust the texture. For walls with special shapes, a texture roller is used to finish the texture. Through the action of the curved plate 6 and the central baffle 7 in the crack-resistant insulation structure, the overall crack resistance and insulation effect of the crack-resistant insulation structure are significantly improved.

[0026] Based on the above, for further improvement of the stability of crack-resistant insulation structures, please refer to [the relevant documentation]. Figure 4 and Figure 6 As can be seen, a groove is provided on the inner side of the curved plate 6, and the upper and lower ends of the middle baffle 7 are provided with protrusions with the same depth as the groove. The protrusions cooperate with the groove, and through the cooperation between the groove and the protrusion, the middle baffle 7 can better support the lateral force and the longitudinal force borne by the curved plate 6, thereby improving the stability of its crack-resistant and heat-insulating structure.

[0027] Based on the above, in order to further improve the stability of crack-resistant thermal insulation structures, please refer to the following: Figure 4 and Figure 5As can be seen, the upper end of the curved plate 6 has an opening that penetrates the surface of the middle baffle 7. A fixing shaft 8 is inserted into the opening, and a connecting post 9 is inserted into the side of any set of middle baffles 7 to fix the fixing shaft 8. Through the action of the fixing shaft 8, the stability of the curved plate 6 and the middle baffle 7 is improved, and the fixing shaft 8 is more firmly fixed through the connecting post 9.

[0028] To increase the contact area between the mortar exterior wall layer 3 and the imitation stone paint intermediate layer 5, please refer to the following for details. Figure 4 As can be seen, the left and right sides of the curved plate 6 are both provided with flat surfaces.

[0029] See Figure 1 and Figure 2 As can be seen, the primer layer 2 is located on the right side of 1, the mortar exterior wall layer 3 is located on the right side of the primer layer 2, and one side of the mortar exterior wall layer 3 is in contact with the left side of the curved plate 6. The right side of the curved plate 6 is provided with the imitation stone paint intermediate layer 5, and the imitation stone paint finishing layer 4 is located on the right side of the imitation stone paint intermediate layer 5.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
