Description

Technical Field

[0001] The utility model belongs to the technical field of building boards, and particularly relates to a sound-insulating building board. Background Technique

[0002] "Building boards" generally refer to board materials used for the structural or non-load-bearing parts of buildings. These boards can be used in a variety of building applications, such as walls, floors, ceilings, etc. According to different usage requirements, building boards can be made of various materials. Sound-insulating building boards are specially designed to reduce sound transmission and are used in construction projects to improve the acoustic isolation effect between spaces.

[0003] For example, a sound-insulating building board with the publication number CN220014080U includes a sound-insulating board and an installation component. The installation component includes an installation board, a clamping joint, and a connecting piece. The sound-insulating board is used to isolate the sound inside and outside the room and reduce noise pollution. When installing the sound-insulating board, first use screws to fix the installation board on the outer side of the wall, install the connecting piece on the sound-insulating board, insert the connecting piece into the installation board and fix it by clamping with the clamping joint. At this time, tighten the connecting piece on the sound-insulating board to complete the installation of the sound-insulating board. The installation component firmly fixes the sound-insulating board on the wall without using cement paste, and the fixing effect will not change due to time, and the fixing is firm and stable, and the phenomenon of the sound-insulating board falling off will not occur, solving the problem that the traditional sound-insulating building board is pasted with cement and the viscosity weakens after long-term use, and the sound-insulating building board is easy to fall off.

[0004] The installation board is fixedly installed on the rear side of the sound-insulating board by cooperating with a spring and a clamping rod. Since the elasticity of the spring will decay after long-term use, the overall strength of the building board will be reduced. At the same time, the clamping rod only relies on the friction between it and the connecting head to be insufficient to support the tight connection between the installation board and the sound-insulating board. To solve the above problems, a sound-insulating building board is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sound-insulating building board to solve the above problems, including:

[0006] A connecting keel, on the front and rear sides of which a sound-insulating cotton and a sound-insulating board are respectively fixedly installed by bolts. A first surface layer is cast on the side of the sound-insulating cotton away from the connecting keel, and a second surface layer is cast on the side of the sound-insulating board away from the connecting keel.

[0007] Through the above technical solution, the sound-insulating cotton and the sound-insulating board are both fixedly installed on both sides of the connecting keel by bolts, and then the first surface layer and the second surface layer are cast on the outer sides of the sound-insulating cotton and the sound-insulating cotton, thereby improving the overall strength of the sound-insulating building board, and at the same time, the process of the sound-insulating building board is simple and convenient for production.

[0008] In a preferred embodiment, a plurality of connecting grooves are equidistantly arranged on the outer wall of the left side of the connecting keel from top to bottom, and a plurality of connecting bosses are equidistantly arranged on the outer wall of the right side of the connecting keel from top to bottom. The positions and data of the connecting grooves and the connecting bosses are the same.

[0009] Through the above technical solution, when two sound insulation building boards are connected for use, the connecting bosses on one side of the sound insulation building board can be inserted into the connecting grooves of the sound insulation building board on the other side. After the connection is completed, connection and fixation are carried out through the threaded rod, which is convenient for connecting the two sound insulation building boards.

[0010] In a preferred embodiment, threaded holes are opened on the outer walls of both the connecting grooves and the connecting bosses.

[0011] In a preferred embodiment, a plurality of partition plates are welded inside the connecting keel, and mounting holes are opened on both the front and rear sides of the plurality of partition plates.

[0012] Through the above technical solution, the sound insulation cotton and the sound insulation board are both connected to the partition plates through the mounting holes.

[0013] In a preferred embodiment, through communication holes are opened at the upper ends of the partition plates.

[0014] In a preferred embodiment, the communication holes at the upper ends of two adjacent partition plates are arranged staggeredly left and right.

[0015] Through the above technical solution, when sound waves enter the maze formed by the partition plates and the communication holes, they are forced to pass through a series of tortuous channels. In this process, the energy of the sound waves will gradually attenuate due to multiple reflections, refractions, and friction with the channel walls.

[0016] In a preferred embodiment, a plurality of circular through holes are opened on the outer wall of the sound insulation board.

[0017] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows: The present utility model provides a sound insulation building board.

[0018] 1. The sound insulation cotton and the sound insulation board are both fixedly installed on both sides of the connecting keel through bolts, and then the first surface layer and the second surface layer are poured on the outside of the sound insulation cotton and the sound insulation cotton, thereby improving the overall strength of the sound insulation building board, and at the same time, the process of the sound insulation building board is simple and convenient for production.

[0019] 2. When two sound insulation building boards are connected for use, the connecting bosses on one side of the sound insulation building board can be inserted into the connecting grooves of the sound insulation building board on the other side. After the connection is completed, connection and fixation are carried out through the threaded rod, which is convenient for connecting the two sound insulation building boards.

[0020] 3. By welding a plurality of partitions inside the connecting keel, and through holes are provided at the upper ends of the partitions. When sound waves enter the maze formed by the partitions and the through holes, they are forced to pass through a series of tortuous channels. In this process, the energy of the sound waves will gradually decay due to multiple reflections, refractions, and friction with the channel walls, improving the sound insulation effect.
