Description
Technical Field
[0001] This utility model relates to the field of building structure device technology, specifically a soundproof building structure. Background Technology
[0002] Currently, water pumps, air conditioning units, fans and other facilities are commonly used in residential or commercial buildings. The noise generated by these devices is mainly low-frequency noise, with a frequency range of 63-250Hz. This type of noise is characterized by its strong penetrating power and can usually travel to a relatively long distance through buildings and air.
[0003] Because equipment is typically placed directly on concrete with rubber pads for sound insulation, the sound insulation effect is poor. Many buildings also have inadequate floor sound insulation, causing vibrations and noise generated during equipment operation to easily propagate through the ground. Previously, the noise was typically blocked by modifying the floor, either by excavating and repaving or by adding a new sound-insulating layer to the existing floor. However, these methods are time-consuming, involve large and complex construction projects, require numerous sound insulation tools and building materials, are costly, and the equipment cannot be moved or reused after construction.
[0004] Therefore, it is necessary to provide a soundproof building structure that can be quickly constructed on existing ground, is easy to move, is reusable, and has good sound insulation performance. Utility Model Content
[0005] This utility model proposes a soundproof building structure to solve the problems mentioned in the background art, and adopts the following technical solution:
[0006] A soundproof building structure is provided on a foundation ground covered with an asphalt layer. The structure includes a movable lifting mechanism, within which multiple layers of soundproof structure are placed. These multiple layers of soundproof structure are laid on the asphalt layer via the movable lifting mechanism. A tray is provided on top of each layer of soundproof structure, and mechanical equipment is mounted on the tray. Several spring damping devices are provided between the tray and the mechanical equipment. Supporting connection structures for connecting the four sides of the tray to the mechanical equipment are provided on the top surface of the four perimeters of the tray.
[0007] Preferably, the spring damping device includes a U-shaped upper base and a U-shaped lower base. The upper base is fixed to the bottom of the mechanical equipment, and the lower base is fixed inside the tray. The protruding end of the upper base is movably connected to the concave part of the lower base. A spring is sleeved on the outer periphery of the protruding end of the upper base, with the upper end of the spring contacting the upper base and the lower end of the spring contacting the lower base. The movable connection between the upper base and the lower base serves as a vertical guide, preventing the mechanical equipment from tilting left or right due to vibration during operation, and works in conjunction with the spring to achieve a damping effect.
[0008] Preferably, the support connection structure includes several lifting lugs (1) fixed to the top surface of the four sides of the tray, and lifting lugs (2) corresponding to the lifting lugs (1) on each of the four sides of the mechanical equipment. A connecting rod connects the lifting lugs (1) and the lifting lugs (2). The connecting rod supports the mechanical equipment and, through the lifting lugs, prevents the mechanical equipment from tilting to the sides during operation. It also limits the height of the lower base and the upper top base, preventing the upper top base from detaching from the recessed part of the lower base.
[0009] Preferably, the concave portion and upper top surface of the lower base, as well as the outer surfaces of the first and second lifting lugs, are all provided with rubber layers. The rubber layers prevent direct contact and collision between the upper and lower bases, providing protection, and also prevent the connecting rod from directly colliding with the first or second lifting lug, generating additional noise. They also provide some shock absorption when the upper and lower bases come into contact.
[0010] Preferably, the movable lifting mechanism includes a square outer frame, and each of the four walls inside the outer frame is provided with a hydraulic cylinder. Each hydraulic cylinder is connected to a support plate at the end opposite to the outer frame. The four support plates are in contact with each other to form an inner frame.
[0011] Preferably, each of the two opposing support plates is equipped with a hydraulic cylinder two at its outer ends, and the movable end of each hydraulic cylinder two is connected to a caster wheel facing downwards. The caster wheel facilitates the adjustment and movement of the lifting mechanism, while the hydraulic cylinder two enables the lifting mechanism to move up and down. When raised, it is convenient to calibrate the vertical position between the corresponding aluminum mold frame and the multi-layer sound insulation structure layer. When lowered, it brings the multi-layer sound insulation structure layer closer to the asphalt layer inside the aluminum mold frame, facilitating the transfer of the multi-layer sound insulation structure layer.
[0012] Preferably, the supporting plate has a sloping support plate on its bottom side opposite to the hydraulic cylinder, and a push-pull handle is provided on the outer side of the outer frame. The push-pull handle facilitates the movement of the entire lifting mechanism. After the hydraulic cylinder extends, the adjacent sides of the four supporting plates are spliced together, and the corresponding four sloping support plates form a square frame structure to support the bottom of the multi-layer sound insulation structure layer. After the hydraulic cylinder retracts, the four supporting plates move away from each other, and the corresponding four sloping support plates detach from the bottom of the multi-layer sound insulation structure layer, thereby transferring the multi-layer sound insulation structure layer onto the asphalt layer.
[0013] Preferably, the multi-layer sound insulation structure includes, from top to bottom, a leveling layer, a first concrete layer, a first rock wool layer, a second concrete layer, and a second rock wool layer. The first concrete layer is 100mm-110mm thick, the second concrete layer is 80mm-100mm thick, the first and second rock wool layers are 40mm-50mm thick, and the asphalt layer is 4mm-8mm thick. The leveling layer is a structural layer used for leveling, slope creation, or reinforcement on the subbase, floor slab, or filling layer. The leveling layer is laid using cement mortar or cement concrete; for example, a cement mortar leveling layer should be applied before waterproofing in bathrooms. Rock wool insulation boards (referred to as rock wool boards) are mainly made from basalt and diabase, with the addition of certain auxiliary materials. They are melted at high temperatures, sprayed into artificial inorganic cotton fibers, and then pressurized and cured to form boards of various specifications. The leveling layer and rock wool layer are common structures in building construction and will not be described in detail here.
[0014] Preferably, silicone sealing rings are provided around the four sides of both the first and second rock wool layers, and steel mesh is laid inside both the first and second concrete layers. The silicone sealing rings protect the first and second rock wool layers and provide auxiliary sound insulation, while effectively preventing concrete slurry from seeping into either layer during pouring. The steel mesh is used to improve the structural strength of the first and second concrete layers.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This utility model pre-casts multiple layers of sound insulation structure and sets up a moving lifting mechanism to move the multiple layers of sound insulation structure. It can be moved and laid at any time on the construction site, and can be reused after construction. This greatly reduces construction costs and difficulty or reduces on-site construction steps. At the same time, because the multi-layer sound insulation structure is built by pre-casting, it achieves effective sound insulation effect and enables sound insulation to be laid anywhere.
[0017] A second hydraulic cylinder is used to raise and lower the entire mobile lifting mechanism, and casters facilitate easy adjustment of its position. A first hydraulic cylinder is also included; its extension and retraction allow the four pallets to be joined together or moved apart, thus enabling the lifting, moving, or lowering of the multi-layered sound insulation structure.
[0018] The pallet prevents the equipment from directly contacting the multi-layered sound insulation structure, thus reducing noise caused by hard impacts. The spring-loaded shock absorption device, formed by the movable connection between the upper and lower base, effectively absorbs vibrations generated during equipment operation, preventing them from being transmitted to the ground. The rubber layer not only enhances the shock absorption effect but also eliminates additional noise generated by direct contact between the various structures. The support connection structure, through the cooperation of connecting rods and lifting lugs one and two, effectively supports the weight of the equipment and limits its tilting in all directions, ensuring equipment stability.
[0019] The high-efficiency sound insulation layer is composed of a leveling layer, a first concrete layer, a second concrete layer, a third rock wool layer, and an asphalt layer. The leveling layer ensures the flatness of the other layers, the first and second concrete layers provide a solid foundation, and the first and second rock wool layers absorb and block sound waves through their porous structure, reducing noise transmission.
[0020] This utility model can be directly constructed and modified on existing ground. The construction structure is simple and easy to operate, the forming speed is fast, the cost is low, and it can be moved and used for construction and reuse at any time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1-6 A soundproof building structure is provided on a foundation ground 1, on which an asphalt layer 36 is laid. The structure includes a movable lifting mechanism 7, within which a multi-layer soundproof structural layer 3 is placed. The multi-layer soundproof structural layer 3 is laid on the asphalt layer 36 via the movable lifting mechanism 7. A tray 4 is provided on top of the multi-layer soundproof structural layer 3, and a mechanical device 2 is mounted on the tray 4. Several spring damping devices 5 are provided between the tray 4 and the mechanical device 2. The top surface of the four sides of the tray 4 is provided with supporting connection structures 6 for connecting the four sides of the mechanical device 2. The multi-layer soundproof structural layer 3 can be adjusted and pre-cast according to the size of the mechanical device 2. During laying, a steel mesh 37 is laid in the first concrete layer 32 and the second concrete layer 34. Silicone sealing rings 38 are set around the four sides of the first rock wool layer 33 and the second rock wool layer 35 to prevent concrete slurry from seeping in. Laying on the asphalt layer 36 via the movable lifting mechanism 7 eliminates the need for on-site pouring at the construction site, reducing material transportation and construction time.
[0030] The spring damping device 5 includes a U-shaped upper base 51 and a U-shaped lower base 52. The upper base 51 is fixed to the bottom of the mechanical equipment 2, and the lower base 52 is fixed inside the tray 4. The protruding end of the upper base 51 is movably connected to the concave part of the lower base 52. A spring 53 is sleeved on the outer periphery of the protruding end of the upper base 51. The upper end of the spring 53 contacts the upper base 51, and the lower end of the spring 53 contacts the lower base 52. The movable connection between the upper base 51 and the lower base 52 serves as a vertical guide, preventing the mechanical equipment 2 from tilting left or right due to vibration during operation, and works with the spring 53 to achieve a damping effect.
[0031] The supporting connection structure 6 includes several lifting lugs 61 fixed to the top surface of the four sides of the tray 4. The mechanical equipment 2 has two lifting lugs 62 corresponding to the lifting lugs 61 on each of its four sides. A connecting rod 63 connects the lifting lugs 61 and the two lifting lugs 62. The connecting rod 63 supports the mechanical equipment 2 and, through the lifting lugs, prevents the mechanical equipment 2 from tilting to the sides during operation. It also limits the height of the lower base 52 and the upper top base 51, preventing the upper top base 51 from detaching from the recessed part of the lower base 52.
[0032] The concave portion and upper surface of the lower base 52, the outer surface of the first lifting lug 61, and the outer surface of the second lifting lug 62 are all provided with rubber layers 54. The rubber layers 54 are used to prevent the upper top seat 51 and the lower base 52 from directly contacting and colliding, thus providing protection, and to prevent the connecting rod 63 from directly colliding with the first lifting lug 61 or the second lifting lug 62, which would generate additional noise. At the same time, they also provide a certain degree of shock absorption when the upper top seat 51 and the lower base 52 come into contact.
[0033] The movable lifting mechanism 7 includes a square outer frame 73. Each of the four walls inside the outer frame 73 is provided with a hydraulic cylinder 71. Each hydraulic cylinder 71 is connected to a support plate 74 at one end opposite to the outer frame 73. The four support plates 74 are in contact with each other to form an inner frame.
[0034] Hydraulic cylinders 72 are respectively installed at both ends of the two opposing support plates 74. The movable end of each hydraulic cylinder 72 is connected to a caster wheel 10 facing downwards. The caster wheel 10 facilitates the adjustment and movement of the lifting mechanism 7. The hydraulic cylinders 72 realize the up and down movement of the lifting mechanism 7. When raised, it is convenient to calibrate the vertical position between the corresponding aluminum mold frame 9 and the multi-layer sound insulation structure layer 3. When lowered, it brings the multi-layer sound insulation structure layer 3 closer to the asphalt layer 36 inside the aluminum mold frame 9, which facilitates the transfer of the multi-layer sound insulation structure layer 3.
[0035] The supporting plate 74 has a sloping support plate 75 on its bottom side opposite to the hydraulic cylinder 72. A push-pull handle 8 is provided on the outer side of the outer frame 73. The push-pull handle 8 facilitates the movement of the entire lifting mechanism 7. After the hydraulic cylinder 71 extends, the adjacent sides of the four supporting plates 74 are joined together, and the corresponding four sloping support plates 75 form a square frame structure to support the bottom of the multi-layer sound insulation structure layer 3. After the hydraulic cylinder 71 retracts, the four supporting plates 74 move away from each other, and the corresponding four sloping support plates 75 detach from the bottom of the multi-layer sound insulation structure layer 3, thereby transferring the multi-layer sound insulation structure layer 3 onto the asphalt layer 36.
[0036] The multi-layer sound insulation structure 3 comprises, from top to bottom, a leveling layer 31, a first concrete layer 32, a first rock wool layer 33, a second concrete layer 34, and a second rock wool layer 35, laid in sequence. The first concrete layer 32 is 100mm-110mm thick, the second concrete layer 34 is 80mm-100mm thick, the first rock wool layer 33 and the second rock wool layer 35 are 40mm-50mm thick, and the asphalt layer 36 is 4mm-8mm thick.
[0037] Silicone sealing rings 38 are provided around the four sides of both rock wool layer 33 and rock wool layer 35. Reinforcing mesh 37 is laid inside both concrete layer 32 and concrete layer 34. The silicone sealing rings 38 protect rock wool layer 33 and rock wool layer 35 and provide auxiliary sound insulation, while effectively preventing concrete slurry from seeping into rock wool layer 33 or rock wool layer 35 during concrete layer 32 and concrete layer 34 pouring. The reinforcing mesh 37 is used to improve the structural strength of concrete layer 32 and concrete layer 34.
[0038] When using this utility model for construction, if the foundation ground 1 does not have an asphalt layer 36, an asphalt layer 36 of the corresponding size of the mechanical equipment 2 is laid on the existing foundation ground 1 in advance. During the laying, an aluminum formwork frame 9 is used to support the asphalt. After the asphalt layer 36 solidifies, the pre-cast multi-layer sound insulation structure layer 3 and the moving lifting mechanism 7 are transported to the construction site. Hydraulic cylinder 71 extends, and the adjacent sides of the four supporting plates 74 interlock. The corresponding four inclined supporting plates 75 form a square frame structure to support the bottom of the multi-layer sound insulation structure layer 3. The pre-cast multi-layer sound insulation structure layer 3 is placed within the four supporting plates 74. The moving lifting mechanism 7 is moved directly above the asphalt layer 36 via the push-pull handle 8. Hydraulic cylinder 72 lowers the moving lifting mechanism 7, bringing the bottom of the multi-layer sound insulation structure layer 3 close to the asphalt layer 36. Hydraulic cylinder 71 retracts, the four supporting plates 74 move away from each other, and the corresponding four inclined supporting plates 75 detach from the bottom of the multi-layer sound insulation structure layer 3, thus transferring the multi-layer sound insulation structure layer 3 onto the asphalt layer 36. The tray 4 is fixed to the top surface of the leveling layer 31, using methods such as concrete fixing or bolt fixing, which are not limited to any particular method. Weld and fix the corresponding upper top seat 51, lower base 52, lifting lug 1 61, lifting lug 2 62 and spring 53 on the pallet 4 and mechanical equipment 2. Finally, connect the corresponding lifting lug 1 61 and lifting lug 2 62 through the connecting rod 63 to complete the installation.
[0039] When it is necessary to remove or change the location of the equipment in the future, hydraulic cylinder 1 71 and hydraulic cylinder 2 72 work to lift the multi-layer sound insulation structure layer 3 again, and move the lifting mechanism 7 to the predetermined position by using casters 10. Then repeat the above operation to lower the multi-layer sound insulation structure layer 3 to realize the position transfer and quick removal of the sound insulation structure. The ground is not damaged during the transfer and no additional tools are required. The operation is simple and the construction efficiency is high.
[0040] This invention can be directly constructed and modified on existing ground. The construction structure is simple and easy to operate, the forming speed is fast, the cost is low, and it can be reused in different places.
