Description

Technical Field

[0001] This utility model relates to the field of composite board technology, and specifically to a sound-insulating composite board. Background Technology

[0002] A composite slab is a building component that is ingeniously combined with a precast slab and a cast-in-place reinforced concrete layer. Specifically, a composite slab consists of a precast base slab (also known as a base plate) and a cast-in-place concrete composite layer (also known as a surface layer).

[0003] For example, the composite slab disclosed in Chinese Utility Model Patent Publication No. CN217580756U includes precast base slab reinforcement, lifting ring reinforcement, connectors, embedded parts, pipelines, and slab surface reinforcement. The connectors include a base and steel truss clips for clamping the steel truss. The steel truss clips are spaced apart on the base, and each steel truss clip has a locking slot that matches the lower chord diameter of the steel truss. The lifting ring reinforcement, embedded parts, and connectors are placed on the precast base slab reinforcement and concrete is poured until the concrete thickness is consistent with the height of the connector base. The lifting rings of the lifting ring reinforcement and the steel truss clips are exposed outside the concrete. After the concrete dries, a precast base slab is formed. Moreover, the thickness of the post-poured concrete of the composite slab only needs to meet the 60mm requirement of the specification to meet the pipe laying requirements of most functional areas, thereby reducing the total thickness of the composite slab and reducing the manufacturing cost of the composite slab.

[0004] Because composite slabs can improve work efficiency, reduce material consumption, are environmentally friendly and energy-saving, and enhance seismic performance, they are widely used in prefabricated buildings. However, in the current use of composite slabs, the sound insulation effect is mostly achieved by relying on the material properties themselves. If cheap sound insulation materials are used, the sound insulation effect of the composite slab will be poor. If expensive sound insulation materials are used, the cost of using the composite slab will increase, which has great limitations and thus affects the use effect of the composite slab. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a sound-insulating composite board, thereby improving the sound insulation effect of the composite board and reducing the cost of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sound-insulating composite board, comprising a composite board body and a sound-insulating component; the composite board body includes a base board body and a surface layer body; the surface layer body is disposed on the surface of the base board body; the sound-insulating component is disposed on the base board body; the sound-insulating component includes a receiving groove and a sound-insulating element; the base board body has a receiving groove; a plurality of the sound-insulating elements are linearly arrayed and fixed in the receiving groove, and a sound-insulating cavity is formed between two adjacent sound-insulating elements.

[0007] Preferably, the sound insulation component is composed of several rhomboid blocks, and the size of the several rhomboid blocks gradually decreases from top to bottom.

[0008] Preferably, it also includes a pressure-bearing component; the pressure-bearing component is arranged in a receiving groove.

[0009] Preferably, the pressure-bearing component includes a pressure-bearing block and a pressure-bearing groove; a plurality of pressure-bearing blocks are fixed in a linear array within the receiving groove, and the pressure-bearing blocks are located between two adjacent sound insulation components; two pressure-bearing grooves are symmetrically opened on both sides of the pressure-bearing block.

[0010] Preferably, the pressure-bearing groove is an isosceles trapezoidal structure, and the opening of the pressure-bearing groove faces outward.

[0011] Preferably, the pressure-bearing component further includes a buffer spring; the buffer spring is fixed in the pressure-bearing groove.

[0012] Preferably, the buffer spring has an arc-shaped structure, and the arc-shaped end of the buffer spring faces outward.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, by setting a sound insulation component, allows noise generated by the collision between the composite slab body and the outside environment to be transmitted to the receiving groove through the surface layer body and the base layer body. Since noise is a sound wave generated by the vibration of an object, the sound wave will continuously impact the inner wall of the receiving groove. When the sound wave impacts the sound insulation component, which is composed of four rhomboid blocks, the sound wave will be continuously refracted and reduced, and they can cancel each other out, thereby achieving the sound insulation effect of the composite slab body. Compared with the prior art, this utility model has a simple and reasonable structure and ingenious design. Through the shape of the sound insulation component, the noise sound waves can be continuously refracted and canceled out, thereby improving the sound insulation effect of the composite slab body and reducing the cost of use. The effect of use is better.

[0015] 2. By setting up a pressure-bearing component, when the composite slab body is subjected to external forces, the force is transmitted to the pressure-bearing block through the surface layer and the base layer, allowing the pressure-bearing block to withstand the forces on the composite slab body, thus initially improving the pressure-bearing capacity of the composite slab body. Furthermore, the forces are transmitted to the pressure-bearing groove. Since the pressure-bearing groove has an isosceles trapezoidal structure, it can disperse and buffer the forces, further improving the pressure-bearing capacity of the composite slab body. At the same time, when the pressure-bearing groove disperses and buffers the forces, the bow-shaped buffer spring can improve the pressure-bearing effect of the pressure-bearing groove and also share the forces received by the pressure-bearing groove. Throughout the process, the forces received by the composite slab body can be buffered multiple times, thereby improving the pressure-bearing capacity of the composite slab body.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a sound-insulating composite board, including a composite board body 1 and a sound-insulating component 2; the composite board body 1 includes a base board body 101 and a surface layer body 102; the surface layer body 102 is arranged on the surface of the base board body 101; the sound-insulating component 2 is arranged on the base board body 101; the sound-insulating component 2 includes a receiving groove 201 and a sound-insulating element 202; the receiving groove 201 is provided in the base board body 101; seven sound-insulating elements 202 are linearly arrayed and fixed in the receiving groove 201, and a sound-insulating cavity is formed between two adjacent sound-insulating elements 202; the sound-insulating element 202 is composed of four rhomboid blocks, and the size of the four rhomboid blocks gradually decreases from top to bottom, which can continuously reduce the sound waves until they are eliminated.

[0026] This invention, by setting a sound insulation component 2, allows noise generated by the collision between the composite board body 1 and the outside environment to be transmitted to the receiving groove 201 through the surface layer body 102 and the base layer body 101. Since noise is a sound wave generated by the vibration of an object, the sound wave will continuously impact the inner wall of the receiving groove 201. When the sound wave impacts the sound insulation component 202, which is composed of four rhomboid blocks, the sound wave will be continuously refracted and reduced, and they can cancel each other out, thereby achieving the sound insulation effect of the composite board body 1. Compared with the prior art, this invention has a simple and reasonable structure and ingenious design. Through the shape of the sound insulation component 202, the noise sound waves can be continuously refracted and canceled out, thereby improving the sound insulation effect of the composite board body 1 and reducing the cost of use. The effect of use is better.

[0027] As a preferred embodiment, it also includes a pressure-bearing component 3; the pressure-bearing component 3 is arranged in the receiving groove 201; the pressure-bearing component 3 includes a pressure-bearing block 301, a pressure-bearing groove 302 and a buffer spring 303; six pressure-bearing blocks 301 are fixed in a linear array in the receiving groove 201, and the pressure-bearing blocks 301 are located between two adjacent sound insulation components 202; two pressure-bearing grooves 302 are symmetrically opened on both sides of the pressure-bearing block 301; the pressure-bearing groove 302 has an isosceles trapezoidal structure, and the opening direction of the pressure-bearing groove 302 is set outward; the buffer spring 303 is fixed in the pressure-bearing groove 302; the buffer spring 303 has an arc-shaped structure, and the arc end of the buffer spring 303 is set outward.

[0028] This invention, by setting up a pressure-bearing component 3, allows the composite slab body 1 to be subjected to external forces when it is subjected to external forces. These forces are transmitted to the pressure-bearing block 301 through the surface layer body 102 and the base layer body 101, enabling the pressure-bearing block 301 to withstand the forces acting on the composite slab body 1. This initially improves the pressure-bearing capacity of the composite slab body 1. Furthermore, the forces are transmitted to the pressure-bearing groove 302. Since the pressure-bearing groove 302 has an isosceles trapezoidal structure, it can disperse and buffer the forces, further improving the pressure-bearing capacity of the composite slab body 1. At the same time, when the pressure-bearing groove 302 disperses and buffers the forces, the bow-shaped buffer spring 303 can improve the pressure-bearing effect of the pressure-bearing groove 302 and also share the forces acting on the pressure-bearing groove 302. Throughout the process, the forces acting on the composite slab body 1 can be buffered multiple times, thereby improving the pressure-bearing capacity of the composite slab body 1.

[0029] Working principle: Noise generated by the collision between the composite slab body 1 and the outside environment is transmitted to the receiving groove 201 through the surface layer body 102 and the base layer body 101. Since noise is a sound wave generated by the vibration of an object, the sound wave will continuously impact the inner wall of the receiving groove 201. When the sound wave impacts the sound insulation component 202, which is composed of four diamond-shaped blocks, the sound wave will be continuously refracted and reduced, and the blocks can cancel each other out, thereby achieving the sound insulation effect of the composite slab body 1. At the same time, when the composite slab body 1 is subjected to external force, it will be transmitted to the pressure block 301 through the surface layer body 102 and the base layer body 101, so that the pressure block 301 can withstand the force. Block 301 can withstand the force exerted on the composite slab body 1, thereby initially improving the pressure-bearing capacity of the composite slab body 1. Furthermore, the force is transmitted to the pressure-bearing groove 302. Since the pressure-bearing groove 302 has an isosceles trapezoidal structure, it can disperse and buffer the force, further improving the pressure-bearing capacity of the composite slab body 1. At the same time, when the pressure-bearing groove 302 disperses and buffers the force, the bow-shaped buffer spring 303 can improve the pressure-bearing effect of the pressure-bearing groove 302 and can also share the force exerted on the pressure-bearing groove 302. Throughout the process, the force exerted on the composite slab body 1 can be buffered multiple times, thereby improving the pressure-bearing capacity of the composite slab body 1.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
