[0081] Example 1

[0082] This embodiment records an installation structure, which is suitable for installing a decorative surface on a corresponding surface to be installed. The installation structure includes a keel 100 and a connecting member 200. One of the keel 100 and the connecting member 200 is arranged on the decorative surface, and the other is arranged on the surface to be installed. The decorative surface is installed on the surface to be installed using the keel 100 and the connecting member 200.

[0083] Specifically, see Figure 1-Figure 3In order to achieve the effect of installing the decorative surface on the surface to be installed, the keel 100 includes a keel body 101 and an extrusion portion 102, the extrusion portion 102 can form a plug-in channel 103, the keel body 101 has a receiving cavity 104, the plug-in channel 103 is connected with the receiving cavity 104, the connecting member 200 includes an extrusion fitting 201, the extrusion fitting 201 has an extrusion fitting portion 2011, under the action of external force, one end of the extrusion fitting portion 2011 is suitable for passing through the The insertion channel 103 formed by the extrusion portion 102 extends into the accommodating cavity 104. After one end of the extrusion fitting portion 2011 passes through the insertion channel 103 and extends into the accommodating cavity 104, the extrusion portion 102 has an extrusion state tending to approach the extrusion fitting portion 2011. In this extrusion state, the extrusion portion 102 is suitable for applying a biasing force to the extrusion fitting portion 2011, so that the extrusion portion 102 and the extrusion fitting portion 2011 maintain abutment against each other, so that the keel is connected to the extrusion fitting 201.

[0084] In this embodiment, see Figure 1-Figure 24The mounting structure is used to mount the decorative surface on the corresponding surface to be mounted. The surface to be mounted is at least one of the top surface, the ground surface and the wall surface. The corresponding decorative surface can be the wall decorative surface 600, the ground decorative surface 800 and the top decorative surface 700. The decorative surface is mounted on the corresponding surface. The mounting structure includes a keel and a connecting member 200. One of the keel and the connecting member 200 is configured on the decorative surface, and the other is configured on the surface to be mounted. The keel includes a keel body 101 and an extrusion portion 102. The extrusion portion 102 is provided on the decorative surface. The pressing portion 102 is suitable for forming a plug-in channel 103. The keel body 101 has a receiving cavity 104. The plug-in channel 103 is connected to the receiving cavity 104. The connecting member 200 includes an extrusion fitting 201. An extrusion fitting portion 2011 is provided on the extrusion fitting 201. Under the action of external force, one end of the extrusion fitting portion 2011 is suitable for passing through the plug-in channel 103 to extend into the receiving cavity 104, thereby completing the connection between the extrusion fitting 201 and the keel, and the extrusion fitting portion 2011 is inserted into the receiving cavity. 104, the extrusion portion 102 on the keel body 101 has an extrusion state tending to approach the extrusion fitting portion 2011. In this extrusion state, the extrusion portion 102 can apply a biasing force to the extrusion fitting portion 2011, so that the extrusion portion 102 and the extrusion fitting portion 2011 are kept pressed against each other, so that the keel and the extrusion fitting piece 201 are kept connected, thereby completing the effect of installing the decorative surface on the surface to be installed, and the installation method is simple. The extrusion fitting portion 2011 of the extrusion fitting piece 201 is inserted into the insertion channel 103 of the keel body 101, so as to achieve the effect of installing the decorative surface on the surface to be installed. The installation structure can be universally installed between the ceiling, floor, wall and decorative surface, and is suitable for the current installation system between the ceiling, floor, wall and decorative surface, which is convenient for the production and installation of the decorative surface, and in the process of production and installation, the complexity of production and installation is reduced, and the operation difficulty of the operator is effectively reduced without considering the installation order between the ceiling, floor, wall and decorative surface, and the subsequent maintenance of the decorative surface is also convenient.

[0085] It should be noted that the universal installation between the ceiling, floor, wall and decorative surfaces refers to that the produced keel structure is universal, and then combined with the extruded fitting 201 of the corresponding structure, the installation can be achieved by simply extending the end of the extruded fitting 201 into the accommodating cavity 104 of the keel. In actual production, the installation between the ceiling, floor, wall and decorative surfaces, the keel plays the main supporting and installation role. Therefore, in this embodiment, the keel is set as a universal structure, which is conducive to the universal installation of the ceiling, floor and wall system.

[0086] For details, see Figure 1-Figure 4In order to further improve the installation stability between the decorative surface and the surface to be installed, the above-mentioned keel includes two relatively arranged bending arms 105, and the two bending arms 105 are suitable for bending into the accommodating cavity 104. The two bending arms 105 are suitable for constituting the above-mentioned extrusion portion 102, so that after the extrusion fitting portion 2011 passes through the extrusion portion 102 to be inserted into the accommodating cavity 104, the two bending arms 105 are pressed against the extrusion fitting portion 2011, so that the extrusion portion 102 of the keel body 101 can apply a biasing force to the extrusion fitting portion 2011, so that the keel body 101 and the extrusion fitting piece 201 are stably connected, further improving the installation stability between the decorative surface and the surface to be installed, and the structure of the keel is simple, which can further reduce the difficulty of production, wherein the above-mentioned extrusion fitting portion 2011 and the extrusion portion 102 are continuously pressed against each other, and when the keel and the connecting member 200 need to be disassembled, the extrusion fitting portion 2011 of the extrusion piece only needs to be withdrawn from the accommodating cavity 104 along the insertion channel 103 to complete the disassembly between the two.

[0087] See also Figure 2 The two bending arms 105 on the above-mentioned keel body 101 are suitable for being arranged relative to each other, and there is a gap between the two bending arms 105 or the two are arranged in abutment with each other. The two bending arms 105 form the plug-in channel 103. By arranging the two bending arms 105 relative to each other and arranging them with a gap or abutment with each other, the plug-in channel 103 can be formed. When the extrusion fitting part 2011 of the extrusion fitting part 201 passes through the plug-in channel 103 and extends into the accommodating cavity 104, the extrusion fitting part 2011 of the extrusion fitting part 201 will stretch the two bending arms 105 apart, thereby entering the accommodating cavity 104, and the bending arm 105 will have a tendency to return to its original state, thereby achieving the effect of applying bias force to the extrusion fitting part 2011.

[0088] Of course, in actual use, the interval may be set slightly larger. In this case, the extrusion fitting portion 2011 of the extrusion fitting piece 201 can be directly inserted into the accommodating cavity 104 more easily, in a loose fitting manner.

[0089] Specifically, see Figure 2 Any of the above-mentioned bending arms 105 includes a first bending edge 1051 and a second bending edge 1052 that are symmetrically arranged. In actual use, at least the first bending edge 1051 is arranged in the accommodating cavity 104 to form a plug-in channel 103. At the same time, the first bending edge 1051 and the second bending edge 1052 have a smooth transition, and a transition section 1053 is provided between the first bending edge 1051 and the second bending edge 1052. The two transition sections 1053 are spaced or abutted against each other, so that there is a spacing or abutment setting between the two bending arms 105, and the pressure between the extrusion fitting portion 2011 and the bending arm 105 is the pressure between the extrusion fitting portion 2011 and the transition section 1053.

[0090] See also Figure 1 The first bending edge 1051 is arranged in the accommodating cavity 104, and the second bending edge 1052 is located at the end of the keel body 101. The two bending edges are arranged at intervals to form the plug-in channel 103.

[0116] In specific use, the ceiling decorative surface 700 is a plurality of adjacent modular ceilings, a ceiling keel 400 is arranged between two adjacent modular ceilings, and the two adjacent modular ceilings are connected together and installed on the ceiling by using the ceiling keel 400. A third extrusion fitting 209 is arranged on the adjacent ends of the two adjacent modular ceilings, and the third extrusion fitting 209 with a planar structure is inserted into the snap-fitting part 212 to maintain connection with the ceiling keel 400, thereby completing the installation between the ceiling and the ceiling 3.

[0117] The third extrusion fitting 209 in this embodiment is integrally formed with the top decorative surface 700 .

[0118] The fastening piece 212 in this embodiment includes a fastening body and a fastening extension section. The fastening body is located in the accommodating cavity 104, and the fastening extension section is located outside the accommodating cavity 104 and is crimped with the wall of the bending arm outside the accommodating cavity.

[0120] The auxiliary keel 210 is a 38 keel. The top keel 400 in this embodiment can achieve the effect of installing the ceiling structure on the top surface 3 by adapting the 38 keel, the clamping piece 211 and the buckle piece 212.

[0121] For sound insulation requirements, see Fig.18 and Fig.19 A sound insulation member 213 may be provided between the fastening member 212 and the top keel 400. The sound insulation member 213 is made of a soft sound absorbing material. Fig.19 The sound insulation member 213 is mainly arranged at the contact portion between the fastening member 212 and the bending arm 105 of the top keel 400. When the third extrusion fitting member 209 is inserted into the fastening member 212, the fastening member 212 and the sound insulation member 213 can be tightly squeezed between the bending arm 105 of the top keel 400, thereby playing the role of sound insulation and shock absorption, and meeting the user's demand for ceiling sound insulation.

[0122] Of course, the top decorative surface 700 in the embodiment may also be made of a soundproof ceiling panel to further improve the soundproofing effect.
