Description

Technical Field

[0001] This invention belongs to the field of building engineering, specifically relating to a building vibration isolation and noise reduction wall structure and construction method. Background Technology

[0002] Ordinary building walls may experience vertical vibrations due to factors such as minor earthquakes, heavy equipment construction, industrial equipment operation, and foundation settlement, which can lead to damage to the building walls and even collapse, resulting in casualties. To minimize vibration-induced losses, the traditional method is to increase the design strength of building structural components, resulting in higher investment and costs. Since the performance of the seismic isolation structure determines the system's isolation effect and seismic resistance, developing high-performance seismic isolation and damping devices has become a key issue in seismic isolation technology.

[0003] High-rise buildings often employ frame structures and other solutions to mitigate the effects of vibrations. However, the general building walls discussed in this application refer to walls of limited height and non-permanent structures, such as courtyard walls, construction site walls, ordinary residential building walls, and single-story building walls. One of the differences between these building walls and those of high-rise buildings is the significant difference in wall height and weight.

[0004] Patent CN121719304B discloses a seismic reinforcement structure and construction method for masonry houses. The walls are made of multiple stacked masonry stones. When constructing walls at the same horizontal height, mortar joints are left between adjacent masonry stones. When the walls are stacked longitudinally, two or more stone slabs are placed on the surface of the lower layer of masonry stones. Then, a stone slab is taken from the ground and pressed onto the upper surface of the stone slab. Mortar joints are left between the longitudinal masonry stones. The mortar joints between the stone slabs are then filled with grout. Then, auxiliary shims are inserted between two longitudinally arranged stone slabs. Finally, auxiliary shims are inserted between two adjacent stone slabs at the same horizontal height. This method has good protective performance and improves seismic strength.

[0005] Furthermore, with increasing demands for noise reduction and environmental protection, as well as rising living standards, the requirements for noise reduction in residential building walls are also becoming more stringent. Building wall structures are primarily composed of concrete walls, adhesive mortar, and masonry blocks, which are insufficient in terms of sound insulation, waterproofing, moisture-proofing, and thermal insulation.

[0012] Preferably, each of the four ends of the reinforced concrete stable layer is provided with a reinforced concrete pouring column, and the bottom of the reinforced concrete pouring column includes a bottom fixing layer, which is fixedly installed in the foundation.

[0013] Preferably, the reinforced concrete stabilizing layer has an annular opening structure.

[0014] Preferably, the height of the convex structure in the middle of the foundation varies with height along the length of the foundation, and the concave structure of the building foundation matches the above variation.

[0015] Preferably, a waterproof layer is provided on one side of the main wall, a sound-absorbing cotton layer is provided on one side of the waterproof layer, a sound-absorbing layer is provided on one side of the sound-absorbing cotton layer, and an environmentally friendly wallpaper layer is provided on one side of the sound-absorbing layer.

[0016] Preferably, a sound-absorbing tube is installed inside the sound-absorbing cotton layer, a sound-absorbing tube is installed inside the sound-absorbing layer, and a sound-absorbing hole is provided on the surface of the sound-absorbing layer, with each sound-absorbing hole corresponding to a sound-absorbing tube inside the sound-absorbing layer.

[0017] Preferably, an insulation layer is provided on the other side of the main wall, a heat insulation cavity is provided on one side of the insulation layer, a heat insulation layer is provided on one side of the heat insulation cavity, and one side of the heat insulation layer is the inner wall surface.

[0018] This invention also discloses a construction method for a building seismic isolation and noise reduction wall structure, including a building seismic isolation and noise reduction wall structure.

[0019] First, the foundation is built, and the foundation includes a convex structure in the middle. The building base is embedded in the convex structure of the foundation. A buffer layer is provided on the inner wall of the foundation, and a shock-absorbing plate is installed at the bottom of the buffer layer. A shock-absorbing spring is installed inside the shock-absorbing plate.

[0020] Secondly, the main wall is formed by stacking blocks on the foundation of the building, and a reinforced concrete stabilizing layer is provided at the connection between the foundation of the building and the main wall.

[0021] Next, a waterproof layer, a sound-absorbing cotton layer, a sound-absorbing layer, and an environmentally friendly wallpaper layer are installed on one side of the main wall in sequence, while an insulation layer, a heat insulation cavity, a heat insulation layer, and an interior wall surface are installed on the other side of the main wall.

[0022] Preferably, the block is an aerated concrete block, and the pores of the block are filled with expanded polystyrene foam; the material inside the sound-absorbing cotton layer is polyester sound-absorbing cotton; the inner wall of the insulation layer is filled with polymer insulation material; the inner wall surface is painted with non-toxic, odorless and environmentally friendly paint; and the buffer layer is EVA foam material.

[0023] Compared with the prior art, the present invention can achieve the following technical effects:

[0024] 1. This invention features a foundation and a building base. The foundation has a convex structure, while the building base has a concave structure. The building base is embedded inside the convex structure of the foundation. This embedded design makes the connection between the foundation and the building base more stable overall, and the lateral and longitudinal seismic isolation effects are better than the traditional direct-entry type. The main wall is formed by stacking masonry blocks on the basis of the building base, and a reinforced concrete stabilizing layer is set at the connection between the building base and the main wall. The reinforced concrete stabilizing layer makes the connection between the main wall and the building base more solid.

[0025] The height of the convex structure in the middle of the foundation varies with height along the length of the foundation, and the concave structure of the building's foundation matches the above variation. This scheme achieves better stability and seismic resistance in both the horizontal and vertical directions of the wall.

[0026] 2. By installing damping plates inside the foundation and damping springs inside the damping plates, this device achieves a vibration isolation effect. By setting a buffer layer at the recess in the foundation, the vibration isolation effect of this device is further improved, enabling vibration isolation in both longitudinal and lateral directions, and making the entire bottom structure more stable. Considering the fatigue of spring metal and the building design life, the selection of damping springs must meet the service life requirements of the wall.

[0027] 3. By setting a sound-absorbing layer and setting sound-absorbing holes inside the sound-absorbing layer, this device can absorb external noise. The absorbed noise passes through the sound-absorbing holes into the sound-absorbing pipe, and the sound-absorbing pipe then guides the noise into the silencer pipe. After passing through the sound-absorbing cotton, the noise is reduced.

[0028] 4. By setting an insulation layer on one side of the main wall, a heat insulation cavity on one side of the insulation layer, and a heat insulation layer on one side of the heat insulation cavity, this device can effectively ensure that the indoor temperature will not be lost and that the outdoor temperature will not shine into the indoor temperature, thus effectively insulating the room.

[0029] 5. By incorporating an environmentally friendly wallpaper layer and interior wall surface, with the interior wall surface being made of environmentally friendly and non-toxic landscape paint, the overall appearance of this device is aesthetically pleasing, green and environmentally friendly, will not harm the human body, and does not contain toxic substances.

[0030] 6. By setting a reinforced concrete stabilizing layer at the connection between the main wall and the building foundation, and setting reinforced concrete pouring columns at all four ends of the reinforced concrete stabilizing layer, the ground end of the reinforced concrete pouring column is connected to the bottom fixing layer, and the bottom fixing layer is fixedly installed at the bottom of the foundation, making the overall stability of the structure stronger and the vibration isolation effect stronger. The four reinforced concrete pouring columns support the structure simultaneously, so that the device will not tilt.

[0031] 7. By setting up a main wall, which consists of multiple blocks made of aerated concrete, and filling the holes in the blocks with expanded polystyrene, this structure not only provides sound insulation but also has a thermal insulation effect. Attached Figure Description
