Description

Technical Field

[0001] The present invention relates to the technical field of sound insulation walls, and more particularly to a building sound insulation wall based on a new material. Background Art

[0002] In the prior art, there is a prefabricated partition wall composed of a front wall panel, a sound insulation layer and a rear wall panel in a stacked manner, and each layer is fixed by bonding. This partition wall is used to divide the indoor space into different areas. In order to facilitate installation, this type of partition wall is usually designed to be larger, and its height is often consistent with the indoor floor height, which makes the overall weight of the partition wall relatively large.

[0003] However, due to the weight of the partition wall and the vibration and inertia that may be encountered during transportation, the gravity exerted by the front and rear wall panels will directly act on the middle sound insulation layer. These external forces may cause the adhesive layer between the wall panels and the sound insulation layer to loosen, thus affecting the stability of the overall structure. Especially during transportation, vibration and inertia further exacerbate this risk, resulting in a decrease in the structural stability and durability of the prefabricated partition wall.

[0004] In summary, this application proposes a building sound insulation wall based on new materials to improve the technical problems mentioned above. Summary of the invention

[0007] Furthermore, in the above-mentioned building sound insulation wall based on the new material, flanges are provided at the left and right ends of wall panel 1 and wall panel 2, which can be engaged with each other to form a limiting effect in the front and rear directions.

[0008] Furthermore, the above-mentioned building sound insulation wall based on new materials also includes frame 1 and frame 2; frame 1 is installed together at the left ends of wall panel 1 and wall panel 2; frame 2 is installed together at the right ends of wall panel 1 and wall panel 2; and a number of fixing holes are opened on frame 1 and frame 2.

[0009] Furthermore, in the above-mentioned building sound insulation wall based on new materials, the sound insulation cotton is set to be a highly elastic sound insulation material.

[0010] Furthermore, in the above-mentioned building sound insulation wall based on the new material, the bonding position between the sound insulation cotton and the wall panel 1 and the wall panel 2 is 1 cm away from the edges of the groove 1 and the groove 2.

[0011] Furthermore, the above-mentioned building sound insulation wall based on the new material also includes a convex strip; a convex strip is arranged on the left and right sides of each sound insulation cotton; and the convex strip is arranged to be a highly elastic sound insulation material.

[0012] Furthermore, in the above-mentioned building sound insulation wall based on the new material, the width of the convex strip is smaller than the thickness of the sound insulation cotton.

[0016] The beneficial effects are: 1. Before installing the soundproof wall based on the new material, the wall panel 1 and the wall panel 2 can be fixed together by bolt 1, bolt 2 and the ring to prevent the sound insulation cotton from being pulled, so as to ensure the basic structural stability. After the soundproof wall based on the new material is installed, the bolt 1 and the bolt 2 can be separated from each other to prevent the sound on both sides of the partition wall from being transmitted through the contacting bolt 1, bolt 2 and the ring. Moreover, after the bolt 1 and the bolt 2 are separated, the left and right adjacent wall panels 1 and the left and right adjacent wall panels 2 can be locked together, which is conducive to improving the partition wall installation process. The stability of the wall panels 1 and 2 is prevented from shaking, which increases the difficulty of installation. During the installation process, there is no need to drill holes on the wall panels 1 and 2, and there is no need to use external structural reinforcements to fix the left and right adjacent wall panels 1 and the left and right adjacent wall panels 2, which reduces the steps of manual installation and is conducive to improving installation efficiency. At the same time, there is no need to apply cement to the gaps between the left and right adjacent wall panels 1 and the left and right adjacent wall panels 2 for fixing. The assembled wall can be easily dismantled and reused manually later, which is very practical for office buildings that often need to change the indoor layout; Second, the sound insulation cotton is set to a highly elastic sound insulation material, so that the sound insulation cotton can rebound to its original shape after being squeezed by bolts one and bolts two, so that the adjacent sound insulation cottons are in close contact to ensure the sound insulation effect. At the same time, the bonding position of the sound insulation cotton and the wall panel one and the wall panel two is set away from the edges of groove one and groove two, so as to provide a sufficient deformation range for the sound insulation cotton when it is squeezed, thereby avoiding the sound insulation cotton from tearing. At the same time, the sound insulation effect at the gap between adjacent sound insulation cottons is enhanced by the convex strips. At the same time, the convex strips will not bulge to the gap between the left and right adjacent wall panels one and two after being squeezed and deformed, thereby avoiding the convex strips from being crushed during the buckling process of wall panels one and two.

[0021] The left and right ends of the wall panel 1 and the wall panel 2 3 are both provided with flanges.

[0022] It also includes a frame 1 7 and a frame 2 8; the left ends of the wall panel 1 1 and the wall panel 2 3 are jointly installed with the frame 1 7; the right ends of the wall panel 1 1 and the wall panel 2 3 are jointly installed with the frame 2 8; and a plurality of fixing holes are opened on the frame 1 7 and the frame 2 8.

[0023] During the transportation and handling of the prefabricated wall, the wall panel 1 and the wall panel 2 3 are fixed together by the cooperation of bolts 1 4, bolts 2 5 and rings 6 to prevent the wall panel 1 and the wall panel 2 3 from moving relative to the sound insulation cotton 2 during transportation and handling, pulling the sound insulation cotton 2 and causing damage to the sound insulation cotton 2, thereby ensuring the basic structural stability of the prefabricated wall.

[0024] In the installation of the building sound insulation wall based on the new material, first, the left side of the frame 7 is manually installed and fixed at the desired position, the lower side of the frame 7 is in contact with the ground and fixed, and the upper side of the frame 7 is in contact with the ceiling and fixed, and then the first assembled wall (consisting of wall panel 1, sound insulation cotton 2 and wall panel 2 3) is installed with Figure 6 The first assembled wall is inserted into the frame 7 in a manner such that the lower side of the first assembled wall contacts the ground and the upper side contacts the ceiling. Then, the four bolts 25 on the first assembled wall are manually screwed with an external hexagonal wrench to move. The front bolt 25 drives the ring 6 to move, so that the ring 6 is away from the rear bolt 25. The ring 6 on the bolt 25 moves to the inside of the raised portion 294, so that the front and rear adjacent bolts 25 move back to back and separate, and the end of the bolt 25 away from the center of the assembled wall is inserted into the fixing hole of the frame 7, the left part of the first assembled wall is locked on the frame 7, and then the second assembled wall is manually placed to the right of the first assembled wall, and then the second assembled wall is pushed to the left to make the second assembled wall move in a Figure 6 The first assembled wall is inserted into the first assembled wall in the manner of being inserted into the first assembled wall. At this time, the protrusion 1 91 is inserted into the corresponding groove 1 92, so that the bolt 1 4 on the first assembled wall is aligned with the round hole 1 93 on the second assembled wall. The protrusion 2 94 is inserted into the corresponding groove 2 95, and the protrusion 3 97 is inserted into the corresponding groove 3 96, so that the round hole 2 98 on the first assembled wall is aligned with the bolt 2 5 on the second assembled wall. Then, the bolt 1 4 and the bolt 2 5 are screwed by the external hexagonal wrench to move the bolts 1 4 adjacent to the front and rear and the front and rear bolts 1 4 adjacent to ... The adjacent bolts 2 5 move away from each other, and the ring 6 on the bolt 1 4 moves to the inside of the raised portion 1 91, so that the bolt 1 4 on the first assembled wall is inserted into the circular hole 1 93 on the second assembled wall, and the bolt 2 5 on the second assembled wall is inserted into the circular hole 2 98 on the first assembled wall, thereby locking the left end of the second assembled wall to the right end of the first assembled wall. Repeat the above operation, and successively install multiple assembled walls on the right end of the second assembled wall. Finally, manually fix the frame 2 8 to Figure 6 , and then screw the bolt 1 4 on the rightmost prefabricated wall into the frame 2 8, and then fix the right side of the frame 2 8 to the building to complete the partition wall construction operation; it should be noted that before installing the prefabricated wall, select the appropriate prefabricated wall size according to the length of the partition wall in advance to ensure that the combined length of the prefabricated wall, frame 1 7 and frame 2 8 is equal to the required length of the partition wall.

[0025] In summary, before the installation of the building sound insulation wall based on the new material, the wall panel 1 and the wall panel 2 3 can be fixed together by bolts 1 4, bolts 2 5 and rings 6 to prevent the sound insulation cotton 2 from being pulled, so as to ensure the basic structural stability of the wall panel. After the installation of the building sound insulation wall based on the new material is completed, the bolts 1 4 and bolts 2 5 can be separated from each other to prevent the sound on both sides of the partition wall from being transmitted through the contacting bolts 1 4, bolts 2 5 and rings 6. Moreover, after the bolts 1 4 and bolts 2 5 are separated, the left and right adjacent wall panels 1 and the left and right adjacent wall panels 2 3 can be locked together, which is beneficial to improve the sound insulation. The stability of the wall installation process prevents the wall panels 1 and 2 and 3 from shaking, which increases the difficulty of installation. There is no need to drill holes on the wall panels 1 and 2 and 3 during the installation process, and there is no need to use external structural reinforcements to fix the left and right adjacent wall panels 1 and 2 and 3, which reduces the steps of manual installation and is conducive to improving installation efficiency. At the same time, there is no need to apply cement to the gaps between the left and right adjacent wall panels 1 and 2 and 3, so that the prefabricated wall can be easily dismantled and reused manually later. This is very practical for office buildings that often need to change the interior layout.

[0026] Example 2 On the basis of Example 1, Figure 3 , Figure 5 and Figure 7 As shown, the sound insulation cotton 2 is configured as a highly elastic sound insulation material.

[0027] The bonding position between the sound insulation cotton 2 and the wall panel 1 and the wall panel 2 3 is 1 cm away from the edge of the groove 1 92 and the groove 2 95 .

[0028] It also includes a convex strip 21; each sound insulation cotton 2 is provided with a convex strip 21 on the left and right sides; the convex strip 21 is set to a highly elastic sound insulation material.

[0029] The width of the convex strip 21 is smaller than the thickness of the sound insulation cotton 2 .

[0030] The protrusion 1 91 is provided with a chamfer, so that the protrusion 1 91 is easier to insert into the groove 1 92 ; the protrusion 2 94 is provided with a chamfer, so that the protrusion 2 94 is easier to insert into the groove 2 95 .

[0031] Wall panel 1 and wall panel 2 3 are both made of new lightweight expanded clay material or glass fiber reinforced cement material, which is convenient for manual handling.

[0032] The side of the wall panel 1 and the wall panel 2 3 away from the sound insulation cotton 2 is provided with a flame retardant layer for flame retardancy.

[0033] The sound insulation cotton 2 is composed of a sound insulation layer and a heat preservation layer, and provides a heat preservation effect through its heat preservation layer.

[0034] During the transportation and installation of this assembled wall, in order to prevent the gravity of wall panel 1 and wall panel 2 3 from directly acting on the sound insulation cotton 2 and tearing it, bolt 1 4, bolt 2 5 and ring 6 can remain connected to support wall panel 1 and wall panel 2 3. After the adjacent assembled walls are buckled together, bolt 1 4 and bolt 2 5 are screwed to separate them, and the second assembled wall is manually pushed to the left to move the second assembled wall to the left. Figure 6 During the process of being inserted into the first prefabricated wall in a manner, the bolt 1 4 on the first prefabricated wall will squeeze the sound insulation cotton 2 on the second prefabricated wall, and the bolt 2 5 on the second prefabricated wall will squeeze the sound insulation cotton 2 on the first prefabricated wall, causing the sound insulation cotton 2 to be concave and deformed, affecting the sound insulation. Therefore, the sound insulation cotton 2 is set to be a highly elastic sound insulation material. During the buckling process of two adjacent prefabricated walls, the bolt 1 4 or the bolt 2 5 will squeeze and deform the sound insulation cotton 2. When the bolt 1 4 and the bolt 2 5 move away from each other, the bolt 1 4 and the bolt 2 5 stop squeezing the sound insulation cotton 2, thereby causing the sound insulation cotton 2 to rebound to its original state, so that the two adjacent sound insulation cottons 2 can be in close contact for sound insulation operation.

[0035] During the interlocking process of adjacent prefabricated walls, the sound insulation cotton 2 will be squeezed by bolt 4 or bolt 2 5. If the bonding position of the sound insulation cotton 2 and wall panel 1 and wall panel 2 3 is close to the edge of groove 1 92 or groove 2 95, the deformation range of the sound insulation cotton 2 is limited when it is squeezed, resulting in the position where the sound insulation cotton 2 contacts the edge of groove 1 92 or groove 2 95 or tearing. Therefore, the bonding position of the sound insulation cotton 2 and wall panel 1 and wall panel 2 3 is set away from the edge of groove 1 92 and groove 2 95, so as to provide a sufficient deformation range for the sound insulation cotton 2 when it is squeezed, thereby avoiding the sound insulation cotton 2 from tearing.

[0036] During the process of adjacent prefabricated walls being fastened to each other, since the convex strips 21 extend beyond the edges of the wall panels 1 and 2, 3, after the wall panels 1 and 2 are fastened and contacted, the left and right adjacent convex strips 21 can be squeezed into a tightly fitting state, thereby enhancing the sound insulation effect at the gaps between the adjacent sound insulation cottons 2. At the same time, the width of the convex strips 21 is set to be smaller than the thickness of the sound insulation cottons 2, so that after the convex strips 21 are squeezed and deformed, their front and rear ends will not exceed the thickness range of the sound insulation cotton 2, that is, after the convex strips 21 are squeezed and deformed, they will not bulge to the gaps between the left and right adjacent wall panels 1 and 2, 3, thereby avoiding the convex strips 21 from being crushed during the fastening process.

[0037] In summary: the sound insulation cotton 2 is set to a highly elastic sound insulation material, so that the sound insulation cotton 2 can rebound to its original shape when squeezed by bolts 1 4 and bolts 2 5, so that the adjacent sound insulation cottons 2 are in close contact to ensure the sound insulation effect. At the same time, the bonding position of the sound insulation cotton 2 and the wall panel 1 1 and the wall panel 2 3 is set away from the edge of groove 1 92 or groove 2 95, so as to provide a sufficient deformation range for the sound insulation cotton 2 when it is squeezed, thereby avoiding the sound insulation cotton 2 from tearing. At the same time, the sound insulation effect of the gap between adjacent sound insulation cottons 2 is enhanced by the convex strips 21. At the same time, the convex strips 21 will not bulge to the gap between the left and right adjacent wall panels 1 and 2 3 after being squeezed and deformed, thereby avoiding the convex strips 21 from being crushed during the buckling process of the wall panels 1 and 2 3.

[0038] The sound insulation cotton 2 consists of a sound insulation layer and a thermal insulation layer.
