[0016] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0017] like Figure 1As shown, a sound insulation wall structure for decoration engineering comprises a light steel keel partition wall 1, sound insulation cotton 2 is adhered inside the light steel keel partition wall 1, a high-density calcium silicon board 3 is arranged on one side of the light steel keel partition wall 1, a gypsum board 1 4 is arranged on the outside of the high-density calcium silicon board 3, a gypsum board 2 5 is arranged on the other side of the light steel keel partition wall 1, a damping sound insulation felt 6 is arranged on the other side of the gypsum board 2 5, a new block wall 7 is arranged on the other side of the damping sound insulation felt 6, and a gypsum board 3 8 is arranged on the other side of the new block wall 7, forming an overall sound insulation wall structure for decoration engineering, achieving sound insulation effect, and having simple and easy construction, easy operation, short construction time, and sound insulation cotton 2 The thickness is 50mm and the weight is 80kg / m³, which ensures good sound insulation effect. The thickness of gypsum board 1 4, gypsum board 2 5 and gypsum board 3 8 is 10mm, the thickness of high-density calcium silicate board 3 is 8mm, the thickness of damping sound insulation felt 6 is 2mm, and the thickness of new block wall 7 is 200mm. Compared with the traditional brick wall structure, it has good structural stability and firmness, is not easy to be damaged or aged during installation and use, has good weather resistance, long service life, and no pollution. Various materials are environmentally friendly and have good flame retardant properties. Combined with the use of water-based latex paint, it can meet the requirements of moving in after decoration.

[0018] The principles and advantages of this utility model: Figure 1As shown, first build a new block wall 7, use 20mm thick plaster to level the wall surface of the new block wall 7, fix the gypsum board 3 8 on the wall surface on one side of the new block wall 7, and fix the damping sound insulation felt 6 on the wall surface on the other side of the new block wall 7. Before laying the damping sound insulation felt 6, it is necessary to move away the large furniture in front of the new block wall 7, measure the area where the damping sound insulation felt 6 needs to be laid, and then cut the damping sound insulation felt 6 according to the measured data. Pay attention to the splicing process and technique. It needs to be fully laid, overlapped and without gaps. The overlap of two damping sound insulation felts 6 is more than 50mm, and at the bottom and the edge of the partition wall, the damping sound insulation felt 6 is cut. It needs to be curled 20mm, and then 20mm thick plaster is used to level the damping sound insulation felt 6, and then the gypsum board 2 5 is fixed on the new block wall 7. The gypsum board 2 5 is fixed by vertical arrangement. During installation, the installation needs to be staggered and close to the new block wall 7 and the damping sound insulation felt 6. It is fixed firmly, firmly and flatly. Draw lines on the ground to determine the position of the light steel keel partition wall 1. The keel is a 50 series light steel keel between the ceiling, the ground and the wall to form a light steel keel partition wall system. Nails are driven in the center of the cross section of the light steel keel partition wall 1. The spacing between the nails is 800. mm, the vertical keel section is rectangular, the sound insulation cotton 2 is attached to the light steel keel partition wall 1, and a 30mm-50mm gap is reserved between the light steel keel partition wall 1 and the gypsum board to fix the rock wool. According to actual needs, when installing and arranging wire tubes and bottom boxes, the distribution boxes, switches, sockets and other electrical openings in the walls of adjacent rooms should also be staggered to prevent perforation. The bulk density of rock wool needs to be measured before use to ensure that the actual weight is greater than 65kg / m3 , professional tools should be used for cutting, the cutting edges should be smooth and neat, the rock wool filling should be fully spread from bottom to top, and it should be installed firmly as required. The rock wool and the light steel keel partition wall 1 are staggered and stuck in the gap on the back of the light steel keel partition wall 1. The rock wool filling needs to be fully spread and compacted, and the splicing should not leave gaps. Then the high-density calcium silicate board 3 is installed on the light steel keel partition wall 1. The high-density calcium silicate board 3 used as the partition wall is arranged longitudinally, that is, the long side of the board falls on the vertical keel. The high-density calcium silicate board 3 should be naturally close when docking, and should not be forced into place. Pay special attention to the discharge of calcium silicate boards at doors and windows. Note that the board seams cannot fall on the keels parallel to the door frame or window frame to avoid silicate damage caused by vibrations generated by frequent opening and closing of doors and windows. The calcium board seams are cracked. The two long sides of the calcium silicate board have been chamfered. When tightening, the board must be nailed to the keel frame. After the calcium silicate board is fixed, all pipeline openings are filled with foam glue to seal the gaps and holes. Regarding gaps and holes, if there are gaps and holes on the partition wall, the sound insulation of the partition wall will be greatly reduced. If the sound insulation of the partition wall itself reaches 50dB, and there are one ten-thousandth of gaps and holes on the wall, the comprehensive sound insulation will drop to 40dB. In order to prevent the gap between the gypsum board wall and the original structure, plastic elastic strips are usually inserted when installing the keel around the wall, and the gypsum board 4 is fixed on the high-density calcium silicate board 3, and the fixing screws are fixed to the light steel keel.At the same time, the gypsum board 1 4 needs to be arranged with the upper layer of high-density calcium silicate board 3 in a staggered manner to form a covering layer. After the gypsum board 1 4 covering layer is completed, the gap is filled with mesh cloth, and then putty is scraped twice and inorganic paint is sprayed three times.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
