Description

Technical Field

[0001] The utility model relates to the technical field of autoclaved aerated concrete plates, in particular to an autoclaved aerated concrete plate for sound insulation and noise reduction. Background Art

[0002] Autoclaved aerated concrete board is a new type of green and environmentally friendly building material with light weight, porous material and different amount of anti-corrosion steel mesh added according to structural requirements. After high temperature, high pressure and steam curing, the autoclaved aerated concrete board with porous crystals is produced. Its density is smaller than that of general cementitious materials, and it has good fire resistance, fire prevention, sound insulation, heat insulation, thermal insulation and other good properties. Therefore, autoclaved aerated concrete board is often used as wall due to its own characteristics.

[0003] The existing autoclaved aerated concrete panels are usually small in area, so during the wall construction process, multiple autoclaved aerated concrete panels need to be spliced ​​and installed to form a complete wall. During the splicing process, due to the individuality of the autoclaved aerated concrete panels, they do not meet the connection conditions, which easily leads to the appearance of joints; at the same time, when the surface of the panel is covered with cement, due to its light weight, the panel is very likely to move, which seriously affects the construction quality and speed. Therefore, a sound-insulating and noise-reducing autoclaved aerated concrete panel is proposed. Utility Model Content

[0022] Figure 1-Figure 3The main structural components of a sound-insulating and noise-reducing autoclaved aerated concrete panel are shown. The sound-insulating and noise-reducing autoclaved aerated concrete panel comprises a concrete panel substrate 1. Both sides of the concrete panel substrate 1 are arranged as mutually matching inlaid structures in opposite directions. A first mounting groove 2 and a first clamping block 3 are arranged in sequence on one side of the concrete panel substrate 1. A second mounting groove 14 and a second clamping block 15 in opposite directions are arranged on the other side of the concrete panel substrate 1. The second clamping block 15 is matched with the first mounting groove 2. A longitudinal steel bar connection frame 11 is arranged inside the concrete panel substrate 1. The upper and lower sides of the longitudinal steel bar connection frame 11 are both provided with equidistantly distributed oblique steel bar connection frames 10. The outside of the longitudinal steel bar connection frame 11 is wrapped with sound insulation cotton 12. The upper and lower sides of the longitudinal steel bar connection frame 11 are both provided with partition layers 9.

[0023] like Figure 2 As shown, the interior of the autoclaved aerated concrete panel for sound insulation and noise reduction is a symmetrical structure, with an oblique steel bar connection frame 10 and a longitudinal steel bar connection frame 11 as the main frame structure, and a fireproof layer 6, a heat insulation layer 7, a waterproof layer 8, a partition layer 9 and sound insulation cotton 12 wrapped around the longitudinal steel bar connection frame 11 are arranged from the outside to the inside, and there is a cavity between the partition layer 9 and the sound insulation cotton 12 for installing the oblique steel bar connection frame 10.

[0024] The fireproof layer 6 is mainly used for flame retardancy to prevent fire.

[0025] The heat-insulating layer 7 is located between the fireproof layer 6 and the waterproof layer 8. The heat-insulating layer 7 is mainly used to isolate heat and play a role in heat preservation.

[0026] A waterproof layer 8 is provided on the inner side of the heat insulation layer 7 , and the waterproof layer 8 is placed between the heat insulation layer 7 and the partition layer 9 .

[0027] The sound-absorbing cotton balls 16 are arranged on the sound-insulating cotton 12, and the sound-absorbing cotton balls 16 are evenly distributed on the sound-insulating cotton 12. The sound-absorbing cotton balls 16 are mainly used to improve the sound absorption efficiency and achieve the effect of silencing.

[0028] like Figure 3 as well as Figure 4As shown, the autoclaved aerated concrete panels for sound insulation and noise reduction are mainly divided into two splicing methods when splicing. When splicing left and right, the mortise and tenon connection method is mainly adopted, and the second clamping block 15 of the right panel is embedded in the first installation groove 2 of the left panel, and so on. Such a connection method can prevent the phenomenon of splicing seams during the connection process, prevent the connection from loosening, and prevent the panels from offsetting when the surface is covered with cement; when splicing up and down, the upper and lower panels are mainly connected by the steel bar connector 13, and the upper end of the steel bar connector 13 is embedded in the connection groove 5 of the lower panel, and the upper end of the steel bar connector 13 is embedded in the connection groove 5 of the upper panel. The connecting steel bar rod 132 in the steel bar connector 13 will pull the fixed steel bar plate 131, and the fixed steel bar plate is fixed inside the connection groove 5, so the two panels can be fixed. After the steel bar connector 13 is fixed, cement is injected into the gap of the connection groove for further fixing.

[0029] like Figure 1 As shown, a cement groove 4 is provided on the concrete plate substrate 1. When multiple concrete plates are spliced, the cement grooves 4 will be close to each other, and the inner edge of the cement groove 4 is an arc shape. When the surface of the concrete plate substrate 1 is subsequently covered with cement, the cement will first fill the cement groove 4, thereby fixing the concrete plate, further improving the stability between the concrete plates, and avoiding the occurrence of mutual displacement between the concrete plates.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
