[0047] Example 2

[0048] In order to improve the convenience of disassembly and assembly of decorative panels, environmental protection and convenient construction, and convenient insertion and maintenance of pipelines in the wall, such as Figure 1-10 As shown, a decorative wall system with a reversibly assembled backing plate according to the present invention comprises a backing plate 1, a decorative panel 3 and a structural adhesive filler 4, wherein a release plastic part 2 for reversibly assembling with the decorative panel 3 is arranged at an equal distance on one side of the backing plate 1, the decorative panel 3 is arranged on one side of the release plastic part 2, the release plastic part 2 and the decorative panel 3 are connected by the structural adhesive filler 4, and a bonding plaster 5 for leveling and bonding with the wall surface is adhered to the side of the backing plate 1 away from the decorative panel 3;

[0049] The backing plate 1 is a thin lining plate 12, and the thin lining plates 12 are provided in a plurality of groups.

[0050] When in use, a wall system is provided for decoration and renovation through the backing plate 1, the release plastic part 2, the decorative panel 3 and the structural adhesive filler 4 to facilitate the reversible assembly of the decorative panel 3, thereby realizing the reversible assembly, greatly improving the convenience and operation efficiency of decoration and renovation, and causing no damage to the wall surface during the process, thereby ensuring the integrity of the building wall surface, reducing the generation of construction waste, having certain environmental protection properties, and realizing green and environmentally friendly construction.

[0051] In order to achieve a non-sticky and snap-fit ​​connection between the structural adhesive filler and the release plastic part, for example, Figure 4 , 6 As shown in , 7, the present invention also includes that the release plastic part 2 is a straw hat-shaped structure, and a filling cavity 21 for filling the structural adhesive filler 4 is opened on one side of the release plastic part 2, and three ribs 22 for buckling with the structural adhesive filler 4 after drying are arranged on the inner wall of the filling cavity 21 at equal distances;

[0052] A corrugated buckle 23 is provided on the outer periphery of the release plastic part 2 away from the filling cavity 21. The release plastic part 2 is made of one of release PET material, release PE material or release PP material. Before the release plastic part 2 leaves the factory, a layer of fluorine release agent or silicon release agent is sprayed on the surface to reduce its surface energy so that it is not easy to produce adhesion when it contacts with other materials, thereby showing a release effect.

[0053] When in use, the filling cavity 21 in the release plastic part 2 provides a filling space for the structural adhesive filler 4, and the three ribs 22 on the inner wall of the filling cavity 21 can form a snap-fit ​​effect on the structural adhesive filler 4 after drying. Even if there is no adhesion effect between the release plastic part 2 and the structural adhesive filler 4, the structural adhesive filler 4 can generate a snap-fit ​​connection with the release plastic part 2 without external pulling force.

[0054] In order to adapt to the wall surface where pipeline troughs have been excavated, for example, Figure 1 , 3 As shown in , 8, the present invention also includes that the thin lining plate 12 includes a thin plate 12 and a plug hole 121 for plugging the release plastic part 2;

[0055] The thin plate 12 includes a flame retardant XPS core layer 122 , a mesh layer 123 and a concrete mortar layer 124 . The mesh layer 123 is coated on both side surfaces of the flame retardant XPS core layer 122 , and the concrete mortar layer 124 is scraped on the mesh layer 123 .

[0056] When in use, the thin plate 12 is assembled on the wall surface where the pipeline trough has been dug, and the bonding gypsum 5 is used to level and bond the back of the thin plate 12 to the wall surface.

[0057] The present invention also includes that the bonding gypsum 5 is a cake-shaped structure, and the structural adhesive filler 4 is a flexible silicone structural adhesive.

[0058] When the present invention is in use, when facing a wall surface without pipeline cavities and requiring pipeline arrangement, the construction personnel select the required number of modules 11 to assemble the wall surface without pipeline cavities. During the process, the redundant modules 11 are cut according to the actual use area of ​​the construction wall surface, and the adhesive gypsum 5 is used to level and adhere the back of the module 11 to the wall surface. The pipelines and lines required for the building are laid through the pipe laying cavity 201 formed between the protrusions 111, thereby reducing the damage to the original pipeline cavities on the wall surface, ensuring the integrity of the wall surface, and reducing the construction waste generated by the wall surface excavation. The round hole 112 in the protrusion 111 on the module 11 is set, so that the release plastic part 2 has a space for full fitting and plugging, and the U-shaped toothed card strip 11 4. The adjacent modules 11 to be spliced ​​and connected are buckled, and when buckling, the two sides of the U-shaped toothed clip 114 are respectively buckled into the concave toothed clip grooves 113 on the edges of the adjacent modules 11, so that the adjacent modules 11 are connected to each other, so as to improve the integrity between the modules and help personnel to better thread the pipes. The corrugated clip 23 end of the release plastic part 2 is inserted into the circular hole 112 in the protrusion 111. By setting the corrugated clip 23 on the back of the release plastic part 2, after the corrugated clip 23 is inserted into the circular hole 112, due to the elastic deformation of the corrugated structure of the corrugated clip 23, a certain prestress can be generated. This prestress helps to maintain a tight connection between the corrugated clip 23 and the circular hole 112. Under dynamic loads such as vibration or impact, the corrugated clip 23 The buckle 23 can better resist loosening, maintain the stability of the connection with the circular hole 112 and the connection strength during use. At the same time, when the corrugated buckle 23 is subjected to the pull-out force, the elastic deformation of the corrugation will absorb part of the energy, thereby improving the pull-out resistance. Before the release plastic part 2 is inserted, the contact surface between the outer surface of the release plastic part 2 and the circular hole 112 is coated with adhesive to improve the connection strength between the release plastic part 2 and the circular hole 112 and achieve a full fit. Then, the filling cavity 21 in the release plastic part 2 is filled with the structural adhesive filler 4. During the filling, the structural adhesive filler 4 is filled after overflowing the filling cavity 21. Subsequently, the back of the decorative panel 3 of the required type is covered on the filling cavity 21 surface of the release plastic part 2, so that the structural adhesive filler 4 adheres to the back of the decorative panel 3. After the glue filler 4 is solidified, the three ribs 22 on the inner wall of the filling cavity 21 can form a snap-fit ​​effect on the solidified structural glue filler 4, so that the release plastic part 2 with a release effect does not produce a sticky effect with the structural glue filler 4, and the structural glue filler 4 can also be snap-fitted to the release plastic part 2 without external pulling. When the decorative panel 3 needs to be disassembled, replaced or maintained in the later stage, the decorative panel 3 can be sucked and pulled in parallel by the suction cup, and the structural glue filler 4 stuck to the back of the decorative panel 3 will be pulled out from the filling cavity 21 with three ribs 22 based on its own elastic expansion force, so that the decorative panel 3 can be disassembled, so that the decorative panel 3 can be replaced and maintained, and the pipeline operation and maintenance in the pipe cavity groove 201 can be carried out, which is convenient to use;

[0059] When faced with the need to repair a wall surface that has been dug with pipeline cavities or does not need to arrange pipelines, the construction personnel select the required number of thin plates 12, assemble the wall surface that has been dug with pipeline cavities or does not need to arrange pipelines through the thin plates 12, and use the adhesive gypsum 5 to level and adhere the back of the thin plates 12 to the wall surface. During this period, the excess thin plates 12 are cut according to the actual use area of ​​the construction wall surface, and the corrugated buckle 23 end of the release plastic part 2 is inserted into the socket 121 of the thin plate 12 to achieve full fit. After the corrugated buckle 23 is inserted into the socket 121, due to The corrugated structure of the corrugated buckle 23 is elastically deformed, which can generate a certain prestress. This prestress helps to maintain a tight connection between the corrugated buckle 23 and the socket 121. Under dynamic loads such as vibration or impact, the corrugated buckle 23 can better resist loosening and maintain the stability of the connection with the socket 121 and the connection strength during use. At the same time, when the corrugated buckle 23 is subjected to a pull-out force, the elastic deformation of the corrugation will absorb part of the energy, thereby improving the pull-out resistance. Subsequently, the filling cavity 21 in the release plastic part 2 is filled with a structural adhesive filler 4. During the filling process, the filling of the structural adhesive filler 4 is completed after it overflows the filling cavity 21. Then, the back of the decorative panel 3 of the required type is covered on the filling cavity 21 of the release plastic part 2, so that the structural adhesive filler 4 adheres to the back of the decorative panel 3. After the structural adhesive filler 4 is dried, the three ribs 22 on the inner wall of the filling cavity 21 can form a snap effect on the dried structural adhesive filler 4, so that the release plastic part 2 with a release effect does not have a sticky effect with the structural adhesive filler 4, and the structural adhesive filler 4 can also be attached to the release plastic part 2 without external force pulling. A snap connection is generated. When the veneer panel 3 needs to be disassembled, replaced or maintained at a later stage, the veneer panel 3 can be sucked and pulled in parallel by the suction cup, and the structural adhesive filler 4 stuck on the back of the veneer panel 3 will be pulled out from the filling cavity 21 with three ribs 22 based on its own elastic expansion force, so that the veneer panel 3 can be disassembled, thereby replacing and maintaining the veneer panel 3; if a thin plate 12 is used and pipelines need to be arranged, a groove for the pipeline to be passed through can be excavated on the thin plate 12 during the construction of the thin plate 12 to meet the requirements of arranging pipelines when the thin plate 12 is used;

[0060] In the process of the structural adhesive filler 4 adhering to the decorative panel 3, before the structural adhesive filler 4 is dried, the position of the decorative panel 3 can be further fine-tuned until the decorative panel 3 is adjusted to the desired adhesive position;

[0061] The construction of the bonding plaster 5 can be completed by using the GL method according to the needs.
