DETAILED DESCRIPTION

[0017] The present application is described in detail below in combination with the drawings and specific examples, but is not limited to the present application.

[0018] Example one, a temperature insulation and heat preservation outer wall plate, as shown in Figures 1-9 , comprising an outer wall plate 1; Also include the bump 102, limit block 103, T-shaped block 104, the first splicing block 105, the second splicing block 106 and the bolt 107;The outer wall plate 1 front transverse linear array is provided with four recesses 101;The outer wall plate 1 back left and right sides are symmetrically provided with a plurality of bumps 102;Two recesses 101 are located in the middle and are provided with two limit blocks 103;The outer wall plate 1 back center and its adjacent left and right linear array is provided with three T-shaped blocks 104;Through the limit block 103 and the T-shaped block 104 cooperation, realize the fixed process of the outer wall plate 1, simultaneously assist its installation to the wall;The outer wall plate 1 upper side is provided with the first splicing block 105;The outer wall plate 1 lower side is provided with the second splicing block 106;The outer wall plate 1 upper side is provided with a plurality of bolts 107;The outer wall plate 1 lower side and each bolt 107 upper and lower symmetric position is provided with a rectangular slot 108, through the bolt 107 and the rectangular slot 108 cooperation, realize the splicing of the outer wall plate 1.

[0019] The protruding length of the bump 102 and the T-shaped block 104 is equal, guarantees the flatness when the outer wall plate 1 and the wall surface fit.

[0020] The bump 102 and the T-shaped block 104 located on the outer wall plate 1 are provided with inclined groove 1001, through the inclined groove 1001 drainage, realize drainage.

[0021] The first splicing block 105 and the second splicing block 106 on the same outer wall plate 1 are staggered, through the first splicing block 105 and the second splicing block 106 of upper and lower adjacent interface, realize the convenient installation of the outer wall plate 1.

[0022] When all the outer wall plate 1 installation is completed, for the wall surface the lowermost outer wall plate 1 bottom surface is provided with a slot, for realizing drainage, for the wall surface the uppermost outer wall plate 1 top surface is provided with a cover plate, for realizing sealing.

[0023] Opposite Figure 1Based on the perspective of the existing technology, the back of the exterior wall panel 1 is flat. During transportation, the stacked exterior wall panels 1 are not fixed, which can easily lead to displacement or collapse, causing damage to the exterior wall panels 1, affecting quality and causing losses. External facilities are needed for fixing. During installation, each exterior wall panel 1 needs to be manually picked up, moved, and fixed one by one, which is time-consuming and labor-intensive, affecting construction efficiency. At the same time, during the installation process, the splicing of two exterior wall panels 1 usually uses external equipment to drill screws to make the two exterior wall panels 1 fit together and fix the back of the exterior wall panel 1 to the wall. Because there are many exterior wall panels 1 to be installed and screws need to be drilled into each exterior wall panel 1, it takes a lot of time and is easy to cause damage and cracking to the wall surface, bringing various risks. In addition, when rainwater seeps into the space between the exterior wall panel 1 and the wall, the rainwater cannot be cleaned because the exterior wall panel 1 is fixed to the wall, causing damage to the exterior wall panel 1 and the wall.

[0024] To solve the above problems, during the transportation of the outer wall panel 1, two outer wall panels 1 are placed on the upper and lower sides respectively during the stacking process. The groove 101 of the lower outer wall panel 1 is aligned with the protrusion 102 and T-shaped block 104 of the upper outer wall panel 1. Then, the upper outer wall panel 1 is pushed, and the bottom surface of each protrusion 102 and each T-shaped block 104 of the upper outer wall panel 1 is in contact with the groove 101 of the lower outer wall panel 1. When the upper and lower outer wall panels 1 are completely aligned, the T-shaped groove formed by the groove 101 of the lower outer wall panel 1 and the two limiting blocks 103 is completely in contact with the T-shaped block 104 of the upper outer wall panel 1, which realizes the limiting and fixing of the upper and lower outer wall panels 1, saves stacking time, and ensures the stability of the outer wall panel 1 during transportation.

[0025] When installing the exterior wall panel 1, during the splicing process, simply push the upper exterior wall panel 1 manually to move it, causing the second splicing block 106 of the upper exterior wall panel 1 to gradually approach the first splicing block 105 of the lower exterior wall panel 1. During this process, the cooperation of the limiting block 103 and the T-shaped block 104 enables pre-assembly without manual positioning, which is more convenient than the existing manual installation that requires positioning and installing each panel one by one. When the second splicing block 106 of the upper exterior wall panel 1 contacts and aligns with the first splicing block 105 of the lower exterior wall panel 1, the pin 107 of the lower exterior wall panel 1 is inserted simultaneously into the rectangular groove 108 of the upper exterior wall panel 1, thus achieving the splicing and fixing of the upper and lower exterior wall panels 1. This effectively solves the problem of difficult manual installation. After installation, multiple exterior wall panels 1 can be fixed to the wall at once, achieving rapid installation and effectively improving installation efficiency and accuracy.

[0026] Meanwhile, when leakage occurs between the exterior wall panel 1 and the wall, and there is moisture between them, by setting protrusions 102 and T-shaped blocks 104 on the back of the exterior wall panel 1, the exterior wall panel 1 is not completely tightly attached to the wall surface, and there is a gap between them, so that the moisture between the exterior wall panel 1 and the wall surface can flow downward, preventing it from accumulating between the exterior wall panel 1 and the wall surface, which would cause the exterior wall panel 1 to fall off, or cause the wall surface to become damp and reduce its stability. Furthermore, a corresponding groove is opened on the bottom surface of the lowest exterior wall panel 1, so that the downward flowing water can be directly discharged between the exterior wall panel 1 and the wall surface, realizing the cleaning of leaked water, solving the problem of difficult water cleaning between the exterior wall panel 1 and the wall surface, and protecting the wall surface from water erosion.

[0027] Furthermore, since the back of the existing exterior wall panel 1 is generally flat, after being attached, it is generally in a tight fit with the wall surface. However, the existing flat exterior wall panel 1 cannot be tightly attached to walls that may be uneven or have protrusions. In this application, protrusions 102 and T-shaped blocks 104 are provided between the exterior wall panel 1 and the wall surface, so that the exterior wall panel 1 has a certain degree of adaptability and can be adapted to fit walls with slight protrusions or unevenness.

[0028] Example 2, based on Example 1, such as Figures 10-13 As shown, it also includes a cleaning assembly, which includes a fixing plate 201, elastic elements 203, and a pressing plate 204; a fixing plate 201 is fixedly attached to a groove 101 at the center of the front of the exterior wall panel 1, and the fixing plate 201 is a hollow structure; a through groove 109 is provided on the back of the exterior wall panel 1; two strip grooves 202 are symmetrically arranged on the left and right sides of the bottom surface of the fixing plate 201, and the strip grooves 202 are connected to the hollow structure inside the fixing plate; several elastic elements 203 are installed in a linear array at the center of the fixing plate 201, and the elastic elements 203 are spring telescopic rods; the top of all the elastic elements 203 are movably connected to a pressing plate 204.

[0029] It also includes a filter screen 1010; a filter screen 1010 is installed at each through groove 109 on the back of the outer wall panel 1, and the filter screen 1010 intercepts impurities to prevent the strip groove 202 from becoming blocked.

[0030] The bottom surface of the pressing plate 204 is attached to the inner side of the fixing plate 201, and the two work together to form a sealed chamber.

[0031] A rubber sealing strip is provided at the contact point between the pressing plate 204 and the outer wall panel 1 to prevent air leakage.

[0032] A thermal insulation exterior wall panel and its installation method include the following steps: S1: Transportation, by engaging the T-block 104 with the protrusion 102, the external wall panel 1 can be transported conveniently; S2: Splicing, pre-splicing is achieved by the first splicing block 105 and the second splicing block 106 cooperating, and quick fixing is achieved by the pin 107 connecting with the rectangular groove 108; S3: Drainage, using the pressing plate 204 to achieve rapid drainage and unblocking between the wall and the exterior wall panel 1.

[0033] After addressing the drainage problem mentioned in the embodiment, during the drainage process, issues such as dust or peeling paint may cause blockage in the gap between the exterior wall panel 1 and the wall, preventing effective drainage. To solve this problem, the pressing plate 204 is manually pressed against one side of the wall, and the pressing plate 204 is reset by the elastic element 203. This repeatedly compresses the air inside the sealed chamber, allowing the air to enter the gap between the exterior wall panel 1 and the wall through the two strip grooves 202 and the two through grooves 109, thus cleaning up dust, paint, and other impurities and preventing blockage.
