Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a soundproof precast cement slab for encasing risers. Background Technology

[0002] The existing precast concrete slabs used for wrapping pipes are usually made of cement and sand. When the drain pipes are draining water or when the flue is ventilating and exhausting smoke, the precast concrete slabs used for wrapping pipes usually cannot reduce the transmission of noise generated by the drain pipes during drainage and flue ventilation and exhaust.

[0003] Therefore, there is an urgent need for a soundproof precast cement slab to encase the riser in order to address the technical problems described above. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a soundproof precast cement slab for pipe wrapping.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a sound-insulating precast concrete slab for pipe wrapping: including an integrally formed precast concrete slab body for pipe wrapping, the inner surface of the precast concrete slab body for pipe wrapping is provided with an interface agent layer, and a sound-insulating coating is uniformly disposed on the interface agent layer.

[0006] As an improvement, the cross-sectional shape of the integrally formed precast concrete slab for the riser is L-shaped or U-shaped.

[0007] As an improvement, the concrete precast slab body for the riser pipe has a honeycomb patterned outer surface.

[0008] As an improvement, the sound-insulating coating material on the inner surface of the interface agent layer is made of inorganic silicon.

[0009] As an improvement, the thickness of the sound-insulating coating on the inner surface of the interface agent layer is 3-8 mm.

[0010] The advantages of this utility model compared with the prior art are as follows: an interface agent layer and a sound insulation coating are provided on the inner surface of the precast concrete slab for wrapping the pipe, which enables the pipe to play a role in sound insulation and noise reduction, reduces the transmission of noise from drainage pipes and flue ventilation, and improves the quietness of the room. At the same time, the sound insulation coating on the inner surface enhances the strength of the precast concrete slab for wrapping the pipe and improves the product quality.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Combined with appendix Figure 1-4 A sound-insulating precast concrete slab for encasing pipes includes an integrally formed precast concrete slab body 1. The cross-sectional shape of the integrally formed precast concrete slab body 1 is L-shaped, but it can also be U-shaped, which is not limited here. The outer surface of the precast concrete slab body 1 is a honeycomb patterned surface; the inner surface of the precast concrete slab body 1 is provided with an interface agent layer 2, and a sound-insulating coating 3 is uniformly disposed on the interface agent layer 2. The sound-insulating coating 3 is made of inorganic silicon material, and the thickness of the sound-insulating coating 3 on the inner surface of the interface agent layer 2 is 3-8mm, which can be set according to the actual situation.

[0019] This solution involves applying an interface agent layer and a sound insulation coating to the inner surface of the precast concrete slab encasing the pipe. This allows the pipe enclosure to function as a sound insulation and noise reduction layer, reducing the transmission of noise from drainage pipes and flue ventilation, thus improving indoor quietness. At the same time, the sound insulation coating 3 on the inner surface enhances the strength of the precast concrete slab encasing the pipe, improving product quality.

[0020] In the description of the embodiments of this utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of the embodiments of this utility model, "a plurality of" means at least two.

[0023] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
