Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation boards, in particular to an exterior wall sound insulation board. Background Art

[0002] Exterior wall sound insulation board is a sound insulation material used for the exterior wall of a building, which is intended to reduce the impact of external noise on the indoor environment. In the prior art, when the sound insulation board is fixed on the exterior wall of the building, multiple sound insulation boards are usually spliced ​​together, and special glue is injected into the splicing parts for fixing. However, in the glue injection project, since the gaps between some sound insulation boards are relatively tight, the flow range of the glue is limited. Later in the use process, due to the changes in thermal expansion and contraction, larger gaps appear in some positions, resulting in poor sound insulation effect at that location. For this reason, the utility model improves the gaps reserved for glue to flow and increases the splicing effect of the sound insulation board. Summary of the invention

[0003] The disclosed embodiment relates to an exterior wall sound insulation board. A positioning card plate is used to position a sound insulation board body that is spliced ​​at multiple locations. Special glue is injected into the interior of a circulation groove through a guide groove. The circulation groove is distributed on the outside of the sound insulation board body, so that the glue is distributed on the outside of the sound insulation board body and flows to the locations where each sound insulation board body is spliced. This allows the glue to flow over a wider range, thereby improving the tightness of the splicing between the sound insulation board bodies and preventing the problem of poor sound insulation effect caused by gaps during later use.

[0004] According to a first aspect of the present disclosure, there is provided an exterior wall sound insulation board, specifically comprising: a sound insulation board body, the sound insulation board body being a rectangular structure, and a protective layer being provided inside the sound insulation board body; a circulation groove being provided on the outside of the sound insulation board body; a guide groove being provided on the top of the sound insulation board body; an inner end of the guide groove being connected to the circulation groove; two storage grooves being provided on the rear side of the sound insulation board body; the storage grooves being a rectangular structure, and two support plates being installed inside the storage grooves.

[0005] Furthermore, a sound absorbing layer is provided inside the sound insulation board body; a plurality of vacuum capsules are provided between the protective layer and the sound absorbing layer; the vacuum capsules are made of hard plastic material, and are hollow structures, and the outer sides of the plurality of vacuum capsules are connected together.

[0006] Furthermore, a plurality of positioning slots are provided at the edge of the front side of the sound insulation board body; grooves are provided on both sides of the positioning slots, and a positioning card plate is slidably installed inside the positioning slots.

[0007] Furthermore, the positioning card plate is a rectangular plate structure, and limit blocks are provided on both sides of the positioning card plate; the limit blocks are slidably installed in the grooves on both sides of the positioning storage tank; a shift block is provided on the outer side of the inner end of the positioning card plate; the shift block is a rectangular structure, and the shift block is slidably installed on the outer side of the positioning storage tank.

[0008] Furthermore, a rotating rod is rotatably installed on the top of the two support plates; the rotating rod is a cylindrical structure, and a threaded hole is opened at one end of the rotating rod, and a fixed plug rod is installed on the outside of the rotating rod, wherein the side end of the fixed plug rod is a conical structure.

[0009] Furthermore, a positioning plate is installed at one end of the rotating rod; a fixing piece is rotatably installed in the threaded hole at one end of the rotating rod; the outer side of the fixing piece is a conical structure, and the outer side of the fixing piece is rotatably installed on the inner side of the positioning plate.

[0010] The utility model provides an exterior wall sound insulation board, which has the following beneficial effects:

[0011] When the utility model is in use, the flow of glue is guided by the circulation groove so that the glue covers the joint parts of the sound insulation board. When the sound insulation board is fixed on the external wall of the building, the positioning card inside the positioning storage groove on one sound insulation board body is moved outward and inserted into the inside of the positioning storage groove outside the other sound insulation board body. The positioning card is used to position the sound insulation board bodies that are spliced ​​at multiple places, and special glue is injected into the inside of the circulation groove through the guidance groove. The circulation groove is distributed on the outside of the sound insulation board body, so that the glue is distributed on the outside of the sound insulation board body, and the glue flows to the joint parts of each sound insulation board body, so that the glue flow range is wider, the tightness of the joints between the sound insulation board bodies is improved, and the problem of poor sound insulation effect caused by gaps in later use is prevented.

[0012] In addition, the sound insulation effect is increased by using vacuum bags. When the sound insulation board is fixed on the outer wall of the building, a plurality of vacuum bags connected together are arranged inside the sound insulation board body. The vacuum bag has a vacuum structure and is light in weight, which reduces the propagation of sound. When other equipment is installed on the sound insulation board at a later time, the fixing bolts penetrating the vacuum bag will not cause leakage in other vacuum bags, so that the vacuum bags in other positions can ensure the sound insulation effect.
