Technical Field

[0001] The invention relates to the technical field of assembled building walls, in particular to an assembled building sound insulation and heat preservation wall. Background Art

[0002] With the acceleration of urban construction and the improvement of people's demand for living environment quality, the construction industry has gradually turned to energy-saving and environmentally friendly prefabricated building systems. The current market generally uses walls assembled from prefabricated components, which to a certain extent simplifies the construction process and shortens the construction period. However, in actual applications, it is found that traditional prefabricated walls are often difficult to achieve good sound insulation and thermal insulation effects.

[0003] Currently, several commonly used methods to improve the sound insulation and thermal insulation performance of prefabricated walls mainly include adding sound-absorbing material layers, setting up cavity structures, and using high-performance thermal insulation panels. Although these methods can improve the sound insulation and thermal insulation performance of walls to a certain extent, they generally have problems such as high cost, complex structure and difficulty in assembly. In particular, there is still much room for improvement in dealing with the thermal bridge effect of walls under different temperature conditions.

The top of each positioning block 42 is connected to the bottom of the wall assembly 3, and the positioning block 42 is connected to the keel 2 on each keel 2 through an expansion bolt.

[0020] Specifically, when the wall component 3 needs to be docked and installed with the keel 2, the positioning block 42 at the bottom of the wall component 3 is pushed to slide inside the positioning groove 41 to complete the preliminary positioning between the wall component and the keel 2, and then the expansion bolts are installed on the keel 2 to connect with the positioning block 42, so that the positioning and installation between the wall component 3 and the keel can be completed.

[0021] Please refer to Figure 3 , the engaging assembly 5 comprises an arc-shaped groove 51 and an arc-shaped block 52; Multiple arc grooves 51 are evenly spaced on one side of the A wall 31 and the D wall 34, and multiple arc blocks 52 are evenly spaced on one side of the A wall 31 and the D wall 34. Multiple arc grooves 51 are evenly spaced on both sides of the B wall 32 and the C wall 33, and multiple arc blocks 52 are evenly spaced on both sides of the B wall 32 and the C wall 33, and each arc groove 51 and arc block 52 are evenly spaced.

[0022] Specifically, when the A wall 31, the B wall 32, the C wall 33 and the D wall 34 are engaged with each other through the arc groove 51 and the arc block 52 in sequence, a longer wall will be formed; when the A wall 31 and the D wall 34 are engaged with each other through the arc groove 51 and the arc block 52, a shorter wall will be formed; by the four sizes of the A wall 31, the B wall 32, the C wall 33 and the D wall 34 cooperating with each other, the wall assembly 3 can be adapted to the installation of base walls 1 of various sizes, thereby improving the assembly efficiency of workers at the construction site and making the gaps between the walls more tightly connected.

[0023] Please refer to Figure 5 Each arc-shaped groove 51 has a cavity 511 therein, and each cavity 511 is filled with natural rubber 512 .

[0024] Specifically, when the room temperature rises, since the arc-shaped side wall of the arc groove 51 is made of synthetic rubber, when the natural rubber 512 expands, it will exert pressure on the alloy arc-shaped side wall, causing the side wall of the arc groove 51 to produce a slight deformation due to the expansion of the natural rubber 512, thereby reducing the gap at the assembly of wall A 31, wall B 32, wall C 33 and wall D 34, thereby further strengthening the tightness of the assembly, effectively blocking or slowing down the transfer of heat at the wall connection, reducing the thermal bridge effect to a certain extent, and being able to further improve the sound insulation and heat preservation effect of the wall assembly 3.

The outermost concrete layer can effectively resist erosion and damage from the external environment and extend the service life of the wall assembly.

[0027] Please refer to Figure 1 , Figure 2 , a support assembly 7 is provided at the bottom end of the wall assembly 3 for supporting the wall assembly 3 and the base wall 1; The support assembly 7 includes a T-slot 71 and an I-beam 72. A plurality of T-slots 71 are provided inside the wall assembly 3. An I-beam 72 is slidably connected inside each T-slot 71. The bottom end of each I-beam 72 is connected to the top of the base wall 1 by an expansion bolt.

[0028] Specifically, the wall assembly 3 is driven to move on the I-beam 72, so that the I-beam 72 slides inside the T-slot 71. Under the action of the I-beam 72, the wall assembly 3 can be supported, and at the same time, the wall assembly 3 can also be limited to prevent the wall assembly 3 from tipping over when it is vertically erected.

[0029] Please refer to Figure 1 The bottom end of the wall assembly 3 is equidistantly connected to a plurality of partition plates 8 , and the bottom end of each partition plate 8 is inserted into the inside of the base wall 1 .

[0030] Specifically, by providing a plurality of partition plates 8, it is possible to provide support between the wall assembly 3 and the base wall 1, and at the same time divide the space between the wall assembly 3 and the base wall 1, thereby helping to reduce the direct transfer of heat between these areas.

[0033] Working principle: The keel is installed and connected to the base wall 1 by expansion bolts, and then the wall assembly 3 is pushed to move on the I-beam 72, so that the I-beam 72 slides inside the T-slot 71, and the positioning block 42 at the bottom of the wall assembly 3 also slides inside the positioning slot 41, thereby completing the preliminary positioning between the wall assembly and the keel 2, and the wall assembly 3 and the base wall 1 are supported by multiple partitions 8, which divide the space between the wall assembly 3 and the base wall 1, which helps to reduce the direct transfer of heat between these areas. By dividing the space, the partition can form a certain heat insulation barrier, thereby reducing the occurrence of thermal bridge effect, which helps to reduce the thermal bridge effect caused by temperature differences, especially in winter and summer; When the A wall 31, the B wall 32, the C wall 33 and the D wall 34 are engaged with each other through the arc groove 51 and the arc block 52 in sequence, a longer wall will be formed; when the A wall 31 and the D wall 34 are engaged with each other through the arc groove 51 and the arc block 52, a shorter wall will be formed; by matching the four sizes of the A wall 31, the B wall 32, the C wall 33 and the D wall 34, the 003 can be adapted to the installation of various sizes of the base wall 1, thereby improving the assembly efficiency of the workers at the construction site, making the gaps between the walls more tightly connected, and when the room When the temperature rises, since the arc-shaped side wall of the arc-shaped groove 51 is made of synthetic rubber, when the natural rubber 512 expands, it will exert pressure on the alloy arc-shaped side wall, so that the side wall of the arc block will produce a slight deformation due to the expansion of the natural rubber 512, so that the gap at the assembly of the A wall 31, the B wall 32, the C wall 33 and the D wall 34 is reduced, thereby further strengthening the tightness of the assembly, effectively blocking or slowing down the heat transfer at the wall connection, reducing the thermal bridge effect to a certain extent, and further improving the sound insulation and heat preservation effect of the wall assembly 3; The wavy plate 62 and the support block 63 are used to improve the bending strength and rigidity of the wall assembly 3. Together with the aluminum honeycomb panel 61 and the sound insulation cotton 64, an effective sound insulation and heat insulation layer can be formed.
