Meanwhile, the decoration of the decorative plate is realized by posting wood fiber wallpaper, so that the old wood fiber wallpaper is only required to be torn off at the later stage, and the new wood fiber wallpaper with the specified color quality is attached again, so that the replacement of the color and the style of the interior wall can be completed, the interior wall can be directly put into use after the replacement is completed, more harmful gas cannot be generated, and the effect of high environmental protection is achieved.

The invention is further provided with: in step S4, after the decorative plate is fixed to the keel, a foaming agent is filled in the space between the decorative plate and the inner wall surface.

Through adopting above-mentioned technical scheme, after the decorative board installation finishes, support the decorative board through filling the foamer, stability when the increase decorative board uses avoids the decorative board phenomenon such as deformation or sunken to appear simultaneously.

The invention is further provided with: the decorative plate comprises a plurality of strip-shaped connecting plates, dovetail blocks are vertically arranged on the inner walls of two ends of each connecting plate, and a sliding groove for embedding the dovetail blocks and a dovetail groove which is communicated with the lower end of the sliding groove and is used for embedding the dovetail blocks in a sliding manner are arranged on the outer wall of the keel from top to bottom; an end plate for compressing the upper end face of the connecting plate is arranged between the upper ends of the keels, sliding blocks embedded into the sliding grooves are vertically arranged on the inner walls of the two ends of the end plate, and locking portions for fixing the sliding blocks in the sliding grooves are arranged on the sliding blocks.

Through adopting above-mentioned technical scheme, when the installation decorative board, with the forked tail piece embedding spout at connecting plate both ends in, then drive connecting plate downstream, the connecting plate drives the forked tail piece and slides along the dovetail inner wall this moment. And when the lower end face of the dovetail block butts against the bottom wall of the dovetail groove, the installation of the lowest connecting plate is realized. Reciprocating in proper order, install polylith connecting plate to fossil fragments to make the upper and lower terminal surface of connecting plate support the back each other, realize assembling of polylith connecting plate, thereby realize assembling of whole decorative board. And finally, taking out the end plate, embedding the sliding blocks at the two ends of the end plate into the sliding grooves, and pressing the lower end surface of the end plate against the upper end surface of the uppermost connecting plate. And finally, after the sliding block is fixed in the sliding groove by using the locking part, the end plate can be fixed, so that the decorative plate is assembled and fixed. When the user needs to change the material of decorative board or the decorative board that has other functions, remove the locking part, then take off the end plate. Then the connecting plate is pulled to move upwards in sequence, so that the decorative plate is detached. Install new decorative board to the fossil fragments in proper order afterwards, can realize the change of decorative board. Therefore, the decorative plate is convenient to assemble and disassemble, so that the decorative plate is easier and more convenient to install and replace, the disassembled decorative plate can be completely recycled, the resource waste is reduced, and the effects of energy conservation and environmental protection are achieved.

The invention is further provided with: the locking part comprises a pair of locking rods which are horizontally arranged, the locking rods are distributed on two sides of the sliding block in an up-down staggered mode, and the inner side wall of the sliding groove is provided with a locking groove for the locking rods to be inserted; a concave cavity is formed in the middle of the sliding block, locking holes communicated with the concave cavity are horizontally formed in the side walls of the two sides of the sliding block, and a spring is horizontally arranged between the end face of one end, located inside the concave cavity, of the locking rod and the inner side wall of the concave cavity; a gear is rotatably connected in the concave cavity and positioned between the pair of locking rods, and racks meshed with the gear are arranged on the sides, close to each other, of the pair of locking rods; be provided with the pivot on the gear, the pivot is worn to establish in proper order the slider and behind the end plate with the outer wall of end plate is neat mutually, and the pivot deviates from be provided with the holding tank of rectangular shape on the one end terminal surface of gear.
