[0002] With the continuous improvement of building energy-saving requirements, exterior wall insulation systems have been widely used in modern buildings. The main purpose of the exterior wall insulation system is to reduce the heat loss of buildings, improve energy utilization efficiency, and improve the comfort of the indoor environment.

[0003] However, in reality, the installation of insulation panels requires precise alignment, which makes construction difficult and prone to gaps and unevenness. These joints are poorly sealed, which can easily lead to rainwater penetration and moisture intrusion, resulting in a cold bridge effect (that is, heat is rapidly transferred through these gaps, forming a heat loss path in these areas). This will significantly reduce the overall performance of the insulation system and increase the building's energy consumption. Utility Model Content

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The assembled exterior wall insulation structure according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, the assembled exterior wall insulation structure of the embodiment of the present invention may include a first plate body 100 , a second plate body 200 , a rubber strip 300 and a bolt 400 .

[0026] Among them, the first plate body 100 is arranged above the second plate body 200, and an inner recess 101 is provided at the bottom of the first plate body 100 close to the wall 600, and a convex portion 201 is provided at the top of the second plate body 200 close to the wall 600, and the inner recess 101 and the convex portion 201 cooperate with each other.

[0027] It should be noted that the raised portion 201 of the second plate body 200 is designed as an upward protruding structure, which is located below the inner recessed portion 101 of the first plate body 100. The cooperation between the raised portion 201 and the inner recessed portion 101 forms a water retaining structure, which effectively prevents the penetration of rainwater. When the rainwater flows downward along the outside, it will be blocked by the raised portion 201 and cannot directly penetrate into the inner side of the first plate body 100 and the second plate body 200.

[0028] A first accommodating groove 102 and a second accommodating groove 202 are respectively provided on opposite sides of the first plate body 100 and the second plate body 200. The rubber strip 300 is provided at the connection between the first plate body 100 and the second plate body 200. Through the provision of the rubber strip 300, the cold bridge effect can be effectively reduced and the thermal insulation effect can be improved.

[0029] The rubber strip 300 is provided with columnar protrusions 301 , which are embedded in the first receiving groove 102 and the second receiving groove 202 .

[0030] As a possible scenario, the first accommodating groove 102 and the second accommodating groove 202 are arc-shaped grooves, and the shape of the columnar protrusion 301 matches the shape of the first accommodating groove 102 and the second accommodating groove 202. By extrusion, the columnar protrusion 301 is deformed so that it completely fits the first accommodating groove 102 and the second accommodating groove 202.

[0031] It should be noted that the columnar protrusions 301 on the rubber strip 300 are deformed by extrusion and completely fit into the first receiving groove 102 and the second receiving groove 202, thereby further enhancing the sealing performance of the connection.

[0032] The bolt 400 passes through the first plate 100 , the rubber strip 300 and the raised portion 201 of the second plate 200 in sequence and is then locked on the wall 600 .

[0033] Specifically, when the relevant staff installs the assembled exterior wall insulation structure of the present invention, they first clean the surface of the wall 600 to ensure that the wall surface is flat and clean.

[0034] Align the raised portion 201 on the top of the second plate 200 close to the wall 600 with the predetermined position on the wall 600, and use mortar 500 or a special adhesive to fix the second plate 200 on the wall 600 to ensure a firm bond.

[0035] Place the rubber strip 300 on top of the second plate 200, ensuring that the columnar protrusion 301 on the rubber strip 300 is aligned with the second receiving groove 202, align the inner recess 101 at the bottom of the first plate 100 close to the wall 600 with the raised portion 201 of the second plate 200, and slowly press the first plate 100 down so that the inner recess 101 and the raised portion 201 are fully matched, ensuring that the columnar protrusion 301 on the rubber strip 300 is completely embedded in the first receiving groove 102 and the second receiving groove 202.

[0036] Finally, pass the bolt 400 through the first plate 100, the rubber strip 300, and the raised portion 201 of the second plate 200 in sequence, and use a wrench or a screwdriver to tighten the bolt 400 on the wall 600 to ensure that the plates are firmly fixed.

[0037] In one embodiment of the present invention, an annular groove 103 is provided on the first plate 100 and the second plate 200 on one side close to the wall 600. The cross-section of the annular groove 103 is a T-shaped groove. Mortar 500 is applied between the wall 600 and the first plate 100 and the second plate 200, and the mortar 500 is squeezed into the annular groove 103.

[0038] In addition, the inner wall of the annular groove 103 is provided with anti-slip grooves to increase the friction between the mortar 500 and the inner wall of the annular groove 103 .

[0039] It should be noted that the cross-section of the annular groove 103 is a T-shaped groove, so that the mortar 500 can form an anchor-like structure after solidification. The mortar 500 not only fills the annular groove 103, but also forms a larger contact area in the groove. When the mortar 500 solidifies, the mortar 500 in the T-shaped groove can form a strong mechanical bite force between the plate and the wall 600, which plays a pulling role, preventing the plate from separating from the wall 600 when subjected to external force, thereby significantly enhancing the bonding force between the plate and the wall 600 and improving the stability of the overall structure.

[0040] In one embodiment of the present invention, the first plate 100 and the second plate 200 both include an insulation layer 110, a waterproof layer 120 and a decorative layer 130, wherein the insulation layer 110, the waterproof layer 120 and the decorative layer 130 are bonded in sequence, and the insulation layer 110 is close to the wall 600.

[0041] Furthermore, reinforcing ribs are provided on the backs of the first plate body 100 and the second plate body 200 , and the shape of the reinforcing ribs is wavy.

[0042] It should be noted that the insulation material of the insulation layer 110 can be polystyrene foam (EPS), extruded polystyrene (XPS), rock wool, etc., which provide the main insulation effect, reduce heat transfer, and improve the energy efficiency of the building; the waterproof layer 120 is located between the insulation layer 110 and the decorative layer 130, and the material of the waterproof layer 120 can be waterproof coating, waterproof breathable membrane, etc., to prevent moisture from penetrating into the insulation layer 110, avoid the insulation material from getting damp, and extend the service life of the insulation layer 110; the decorative layer 130 is located on the outermost side, and commonly used decorative materials include paint, tiles, metal plates, etc., to provide an aesthetically pleasing appearance and enhance the decorative effect of the building.

[0043] In addition, the wavy reinforcing ribs can increase the contact area with the mortar 500 and improve the adhesion strength.

[0044] In summary, according to the prefabricated exterior wall insulation structure of the embodiment of the present invention, an upward protrusion 201 is provided through the second plate body 200 below, and an inner recess 101 matching the protrusion 201 is provided at the lower part of the first plate body 100, which can reduce the infiltration of rainwater in the gap. In addition, by arranging a rubber strip 300 at the connection, the connection gap can be made smaller, and the columnar protrusion 301 is squeezed into the first accommodating groove 102 and the second accommodating groove 202 to ensure the sealing effect, reduce the heat exchange between the inside and the outside, and improve the overall performance of the insulation system.
