Description

Technical Field

[0001] The utility model relates to the field of precast walls, and more specifically, to a fireproof and sound-insulating assembled wall. Background Art

[0002] An assembled wall is a wall that is pre-cast and then transported to the assembly site for casting and connection. The assembled wall reduces the on-site casting work, shortens the construction time, and reduces environmental problems such as dust dispersion generated by casting. It is widely used. Existing assembled walls can obtain corresponding performances by setting some functional units inside or on the surface. When sound-insulating boards and sound-absorbing boards are set inside the assembled wall, the assembled wall will have a certain sound-insulating and noise-reducing function. However, due to strength requirements, the space inside the wall for setting sound-insulating boards and sound-absorbing boards is limited, and the sound-insulating and noise-reducing function is weak.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a fireproof and sound-insulating assembled wall.

[0005] The above technical purpose of the present utility model is achieved through the following technical solutions: A fireproof and sound-insulating assembled wall includes a casting part, in which a sound-insulating board, a sound-absorbing board, and sound-absorbing columns are provided. The sound-absorbing columns are located on the side of the sound-absorbing board away from the sound-insulating board. The sound-absorbing columns are arranged at intervals along the width direction of the sound-absorbing board. The cross-section of the sound-absorbing column is trapezoidal, and the small end of the trapezoidal cross-section of the sound-absorbing column is located on the side where the large end of the trapezoidal cross-section of the sound-absorbing column is close to the sound-absorbing board.

[0006] The present utility model is further provided that: A sound-insulating pad is fixedly connected to the side of the sound-absorbing column close to the sound-absorbing board, and a number of through holes are provided on the sound-insulating pad.

[0007] The present utility model is further provided that: The surface of the sound-insulating pad fits the surface of the sound-absorbing column.

[0008] The present utility model is further provided that: The thickness of the sound-absorbing board is greater than the thickness of the sound-insulating board.

[0009] The present utility model is further provided that: A number of grooves are provided on the side of the sound-absorbing board away from the sound-insulating board, and the grooves are linearly arrayed on the sound-absorbing board.

[0010] The present utility model is further provided that: The cross-section of the groove is semi-circular.

[0011] The present utility model is further provided that: A sound-insulating coating is provided on the surface of the casting part.

[0012] The utility model is further arranged such that: a plurality of reinforcing bars are provided in the pouring part.

[0013] In summary, the utility model has the following beneficial effects: the pouring layer fills the intervals between the sound-absorbing columns, improving the supporting effect of the pouring layer. Part of the sound waves pass through between the sound-absorbing columns, are reflected by the sound-insulating board after passing through the sound-absorbing board, and pass through the sound-absorbing board again. At the same time, because the cross-section of the sound-absorbing column is trapezoidal, part of the folded sound waves will be captured and absorbed by the sound-absorbing column again, improving the noise reduction performance of the wall.

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] Embodiment: A fireproof and sound-insulating prefabricated wall, as Figure 1 、 Figure 2 shown, includes a pouring part 1, in which a sound-insulating board 2, a sound-absorbing board 3 and sound-absorbing columns 4 are provided. The sound-absorbing columns 4 are located on the side of the sound-absorbing board 3 away from the sound-insulating board 2. The sound-absorbing columns 4 are arranged at intervals along the width direction of the sound-absorbing board 3. The cross-section of the sound-absorbing column 4 is trapezoidal. The small end of the trapezoidal cross-section of the sound-absorbing column 4 is located on the side where the large end of the trapezoidal cross-section of the sound-absorbing column 4 is close to the sound-absorbing board 3. A sound-insulating coating 7 is provided on the surface of the pouring part 1, and a plurality of reinforcing bars 8 are provided in the pouring part 1.

[0020] Specifically, the sound insulation board 2 and the sound absorption board 3 are mutually attached, and the pouring layer is formed by pouring and covers the sound insulation board 2, the sound absorption board 3 and the sound absorption columns 4. In this embodiment, both the sound absorption columns 4 and the sound absorption board 3 are made of polyester fiber. The sound insulation board 2 is composed of sound insulation cotton, gypsum board and sound insulation felt. The thickness of the pouring layer is greater than the thickness of the sound absorption board 3 and the sound insulation board 2. The pouring layer fills the intervals between the sound absorption columns 4, improving the supporting effect of the pouring layer and ensuring the strength of the wall. When sound waves reach the sound absorption columns 4, some sound waves pass through the sound absorption columns and the sound absorption board 3 in sequence and are absorbed by both, and some pass through between the sound absorption columns 4, are reflected by the sound insulation board 2 after passing through the sound absorption board 3, and pass through the sound absorption board 3 again. At the same time, because the cross-section of the sound absorption columns 4 is trapezoidal, some of the reflected sound waves will be captured and absorbed by the sound absorption columns 4 again, improving the noise reduction performance of the wall. In this embodiment, the sound insulation coating 7 adopts a water-based coating composed of acrylic emulsion, mica powder, polymer damping agent, damping mineral filler and flame retardant, improving the sound insulation performance and fire resistance of the wall surface. The reinforcing steel bars 8 are distributed between the sound absorption columns 4 and on the side of the sound insulation board 2 away from the sound absorption board 3, further improving the strength of the wall through the reinforcing steel bars 8.

[0021] As Figure 1 , Figure 2 , Figure 3 shown, a sound insulation pad 5 is fixedly connected to the side of the sound absorption column 4 close to the sound absorption board 3. A number of through holes 9 are formed in the sound insulation pad 5. The surface of the sound insulation pad 5 fits the surface of the sound absorption column 4. Specifically, in this embodiment, the sound insulation pad 5 is made of sound insulation cotton. The three side walls of the sound absorption column 4 close to the sound absorption board 3 are all in contact with the sound insulation pad 5. The through holes 9 are linearly arrayed on the sound insulation pad 5. The sound insulation board 2 with a hole structure increases the structural complexity between the sound absorption column 4 and the sound absorption board 3, improving the sound wave capture ability of the wall.

[0022] As Figure 1 , Figure 2 shown, the thickness of the sound absorption board 3 is greater than the thickness of the sound insulation board 2. A number of grooves 6 are formed on the side of the sound absorption board 3 away from the sound insulation board 2. The grooves 6 are linearly arrayed on the sound absorption board 3. The cross-section of the grooves 6 is semi-circular. Specifically, the grooves 6 are vertically arranged, and the array direction of the grooves 6 is the same as the array direction of the sound absorption columns 4. By increasing the thickness of the sound absorption board 3, the residence time of sound waves in the sound absorption board 3 is further increased. The grooves 6 form a concave-convex structure with a curved surface on the sound absorption board 3, increasing the structural complexity at the junction of the pouring part 1 and the sound absorption board 3 and improving the sound absorption effect of the sound absorption board 3.

[0023] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
