Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a sound-insulating and vibration-damping floating platform. Background Technology

[0002] According to building structure design codes, super high-rise buildings exceeding 100m in height are required to have refuge floors. Large mechanical and electrical equipment (such as cooling towers) is typically housed in the roof and refuge floors.

[0003] Please see the appendix Figure 1 When large mechanical and electrical equipment is installed on the roof, the equipment foundation 2 of the equipment 1 is cast simultaneously with the roof structural floor slab 3. During operation, the equipment inevitably generates significant noise and vibration, which are directly transmitted to the roof structural floor slab, impacting the comfort of the lower floors. Similarly, large mechanical and electrical equipment located in refuge floors also affects the comfort of the lower floors; the more refuge floors there are, the more floors are affected by the noise and vibration from the large mechanical and electrical equipment. Therefore, a sound-insulating and vibration-damping floating platform is needed to solve the problem of noise and vibration from the operation of large mechanical and electrical equipment affecting the comfort of the lower floors in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a soundproof and vibration-damping floating platform that can solve the problem of noise and vibration generated by the operation of large electromechanical equipment affecting the comfort of the lower level in the prior art.

[0005] This utility model is implemented as follows:

[0006] A sound-insulating and vibration-damping floating platform includes a structural inverted beam, a sound-insulating and vibration-damping structure, and vibration-damping materials. The structural inverted beam is constructed on the roof structural floor slab, and the structural inverted beam has a ring structure and is integrally cast with the roof structural floor slab, forming a floating platform for the installation of large electromechanical equipment between the structural inverted beam and the roof structural floor slab. The sound-insulating and vibration-damping structure is constructed within the floating platform, and the large electromechanical equipment is installed on the sound-insulating and vibration-damping structure through equipment foundations. A vibration-damping gap is formed between the side wall of the sound-insulating and vibration-damping structure and the inner side wall of the structural inverted beam, and the vibration-damping materials are placed within the vibration-damping gap.

[0007] The aforementioned sound insulation and vibration isolation structure includes a leveling layer, a roof waterproofing layer, a protective layer, a sound insulation layer, a seepage-proof and waterproofing layer, and an installation floor slab. The leveling layer is laid on the roof structural floor slab within the floating platform. The roof waterproofing layer is fully laid on the roof structural floor slab, structural inverted beams, and leveling layer. The protective layer is constructed on the roof waterproofing layer within the floating platform. The sound insulation layer is laid on the protective layer. The seepage-proof and waterproofing layer is laid on the sound insulation layer. The installation floor slab is constructed on the seepage-proof and waterproofing layer. Large electromechanical equipment is installed on the installation floor slab through equipment foundations.

[0008] The protective layer is a fine aggregate concrete layer.

[0009] The sound insulation layer includes sound-absorbing cotton and sound-insulating blocks. The sound-absorbing cotton is fully laid on the protective layer, and several sound-insulating blocks are spaced apart on the sound-absorbing cotton.

[0010] The sound-absorbing cotton is provided with several vibration isolation blocks at intervals, and the vibration isolation blocks and sound insulation blocks are arranged alternately, with several vibration isolation blocks and several sound insulation blocks fully covering the sound-absorbing cotton.

[0011] The aforementioned waterproof and seepage-proof layer includes a steel plate layer and a seepage-proof membrane. The steel plate layer is laid on several vibration isolation blocks and several sound insulation blocks, and the seepage-proof membrane is laid on the steel plate layer.

[0012] The installation floor slab is a reinforced concrete floor slab, and the installation floor slab is cast integrally with the equipment foundation.

[0013] The top surface of the installation floor slab is higher than the top surface of the vibration-resistant material, and the top of the vibration-resistant material is sealed with the installation floor slab and the structural inverted beam using a sealing material.

[0014] The structural inverted beam is provided with several drainage holes at intervals, so that the inside of the floating platform is connected to the outside of the floating platform through the drainage holes, and the drainage holes are higher than the installation floor slab.

[0015] According to the sound insulation and vibration isolation floating platform as claimed in the claim, the structural inverted beam is a reinforced concrete inverted beam, and the stirrups of the structural inverted beam are anchored into the roof structural floor slab.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. Because this utility model has a sound insulation and vibration isolation structure, the noise and vibration generated by the operation of large electromechanical equipment are first transmitted to the 150mm thick reinforced concrete floor slab, i.e. the installation floor slab, and then isolated by sound insulation cotton, sound insulation blocks and vibration isolation blocks, so as not to affect the roof structure floor slab below, thereby improving the comfort of the floor below the equipment floor.

[0018] 2. Because the present invention has a structural inverted beam at the edge of the sound insulation and vibration isolation structure, it can prevent the sound insulation and vibration isolation structure from lateral slippage caused by the vibration of large electromechanical equipment during operation. The structural inverted beam and the sound insulation and vibration isolation structure are connected by a vibration-resistant material, which can not only limit the lateral slippage of large electromechanical equipment, but also prevent the vibration from being transmitted to the inverted beam structure.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Please see the appendix Figure 2 A sound-insulating and vibration-damping floating platform includes a structural inverted beam 4, a sound-insulating and vibration-damping structure, and vibration-damping material 5. The structural inverted beam 4 is constructed on the roof structural floor slab 3 and has a ring structure. It is integrally cast with the roof structural floor slab 3, forming a floating platform for the installation of large electromechanical equipment 1 between the structural inverted beam 4 and the roof structural floor slab 3. The sound-insulating and vibration-damping structure is constructed within the floating platform, and the large electromechanical equipment 1 is installed on the sound-insulating and vibration-damping structure through the equipment foundation 2. A vibration isolation gap is formed between the side wall of the sound-insulating and vibration-damping structure and the inner side wall of the structural inverted beam 4, and the vibration-damping material 5 is placed within the vibration isolation gap.

[0032] By constructing sound insulation and vibration isolation structures, the large electromechanical equipment 1 is installed within a floating platform, separated from the roof structural floor slab 3. This prevents the vibrations and noise generated during the operation of the large electromechanical equipment 1 from being directly transmitted to the roof structural floor slab 3, thereby improving the user comfort of the floors below the large electromechanical equipment 1. The roof structural floor slab 3 can also serve as the floor slab of a refuge floor, used for the installation of the large electromechanical equipment 1 within the refuge floor.

[0033] The installation of the structural inverted beam 4 forms lateral protection around the sound insulation and vibration isolation structure. Furthermore, the structural inverted beam 4 is integrally cast with the roof structural floor slab 3, effectively limiting its movement and preventing the vibration generated by the operation of the large electromechanical equipment 1 from causing displacement of the sound insulation and vibration isolation structure and the equipment 1. Simultaneously, the structural inverted beam 4 and the sound insulation and vibration isolation structure are flexibly connected by vibration-resistant material 5, further enhancing the vibration reduction effect.

[0034] Please see the appendix Figure 2 The sound insulation and vibration isolation structure includes a leveling layer 7, a roof waterproofing layer 8, a protective layer 9, a sound insulation layer 10, a seepage-proof and waterproofing layer 11, and an installation floor slab 12. The leveling layer 7 is laid on the roof structural floor slab 3 within the floating platform. The roof waterproofing layer 8 is fully laid on the roof structural floor slab 3, the structural inverted beam 4, and the leveling layer 7. The protective layer 9 is constructed on the roof waterproofing layer 8 within the floating platform. The sound insulation layer 10 is laid on the protective layer 9. The seepage-proof and waterproofing layer 11 is laid on the sound insulation layer 10. The installation floor slab 12 is constructed on the seepage-proof and waterproofing layer 11. Large electromechanical equipment 1 is installed on the installation floor slab 12 through the equipment foundation 2.

[0035] The leveling layer 7 is used to level the bottom, ensuring the levelness after the subsequent installation of large electromechanical equipment 1, which helps to reduce the operating noise and vibration of large electromechanical equipment 1.

[0036] The roof waterproofing layer 8 is the waterproofing structure for the entire roof structural floor slab 3. When waterproofing the roof structural floor slab 3, waterproofing construction is carried out simultaneously on the structural inverted beam 4 and the floating platform.

[0037] The protective layer 9 is used to support the large electromechanical equipment 1 and to protect the roof waterproofing layer 8 inside the floating platform.

[0038] The sound insulation layer 10 is used to isolate the operating noise and vibration of large electromechanical equipment 1, and to prevent noise and vibration from being directly transmitted to the roof structure floor slab 3 and affecting the comfort of the lower floor.

[0039] The waterproof and seepage-proof layer 11 is used to improve the waterproof and seepage-proof performance of the entire sound insulation and vibration isolation structure.

[0040] The installation floor slab 12 is used to provide an installation platform for large electromechanical equipment 1. The equipment foundation 2 of the large electromechanical equipment 1 is constructed simultaneously on the installation floor slab 12. The operating noise and vibration of the large electromechanical equipment 1 are first transmitted to the installation floor slab 12, avoiding the direct impact of operating noise and vibration on the lower floor caused by the equipment foundation 2 being directly constructed on the roof structure floor slab 3 in the prior art.

[0041] Please see the appendix Figure 6 The protective layer 9 is a fine aggregate concrete layer.

[0042] The specifications and materials of protective layer 9 can be adapted to meet actual construction needs.

[0043] Please see the appendix Figure 7 The sound insulation layer 10 includes sound-absorbing cotton and sound insulation blocks 101. The sound-absorbing cotton is fully laid on the protective layer 9, and several sound insulation blocks 101 are spaced apart on the sound-absorbing cotton.

[0044] Preferably, the sound-absorbing cotton can be made of sound-absorbing materials with quartz sand, limestone, dolomite, etc. as the main raw materials, and its specifications can be adapted to the actual use requirements. The sound insulation block 101 can be made by cutting sound insulation board, and the size, quantity and arrangement spacing of the sound insulation block 101 can be adjusted according to the actual construction requirements.

[0045] Please see the appendix Figure 7 The sound-absorbing cotton is provided with a number of vibration isolation blocks 102 at intervals. The vibration isolation blocks 102 and the sound insulation blocks 101 are arranged alternately, and the vibration isolation blocks 102 and the sound insulation blocks 101 are fully covered on the sound-absorbing cotton.

[0046] Preferably, the vibration isolation block 102 can be made of materials such as rubber, which has a good vibration isolation and damping effect. The vibration isolation block 102 and the sound insulation block 101 are spliced ​​together to form a complete plane, which not only has the effect of vibration isolation and sound insulation, but also facilitates the construction of the structural layer above it.

[0047] Please see the appendix Figure 8 The seepage-proof and waterproof layer 11 includes a steel plate layer and a seepage-proof membrane. The steel plate layer is laid on a number of vibration isolation blocks 102 and a number of sound insulation blocks 101, and the seepage-proof membrane is laid on the steel plate layer.

[0048] By laying steel plate layers and impermeable membranes, a double-layer waterproof and seepage-proof effect can be achieved, ensuring the waterproof performance of the entire floating platform.

[0049] Please see the appendix Figure 9 The installation floor slab 12 is a reinforced concrete floor slab, and the installation floor slab 12 is integrally cast with the equipment foundation 2.

[0050] The floor slab 12 is used to support the large electromechanical equipment 1 and to transmit the vibration and noise of the large electromechanical equipment 1 during operation downward to the sound insulation layer 10. The sound insulation layer 10 isolates the vibration and noise, thus avoiding affecting the comfort of the lower floor.

[0051] Please see the appendix Figure 10 The top surface of the installation floor slab 12 is slightly higher than the top surface of the vibration-resistant material 5, and the top of the vibration-resistant material 5 is sealed with the installation floor slab 12 and the structural anti-reflective beam 4 by a sealing material 6.

[0052] The structural anti-reflective beam 4 is flexibly connected to the sound insulation and vibration isolation structure through the vibration-resistant material 5 and sealed with the sealing material 6 to ensure the waterproof performance of the vibration isolation gap.

[0053] Please see the appendix Figure 10 The structural inverted beam 4 is provided with several drainage holes 41 at intervals, so that the inside of the floating platform and the outside of the floating platform are connected through the drainage holes 41. The drainage holes 41 are higher than the installation floor slab 12.

[0054] The drainage hole 41 is designed to prevent water from accumulating inside the auxiliary platform. When the water level reaches the drainage hole 41, it can be drained quickly through the drainage hole 41.

[0055] The aforementioned structural inverted beam 4 is a reinforced concrete inverted beam, and the stirrups of the structural inverted beam 4 are anchored into the roof structural floor slab 3 to ensure the structural integrity of the structural inverted beam 4 and the roof structural floor slab 3.

[0056] Please see the appendix Figure 2 To be continued Figure 10 The construction process of this utility model is as follows:

[0057] Please see the appendix Figure 3 Step 1: During the construction of the roof structural floor slab 3, the structural inverted beam 4 is poured simultaneously, and the stirrups of the structural inverted beam 4 are anchored into the roof structural floor slab 3, so that the structural inverted beam 4 and the roof structural floor slab 3 form an integral structure, and a floating platform for installing large electromechanical equipment 1 is formed between the inner side of the structural inverted beam 4 and the roof structural floor slab 3.

[0058] Please see the appendix Figure 3 Step 2: Reserve a drainage hole 41 with a size of φ25 in the structural inverted beam 4, and set the drainage holes 41 at intervals of 1000mm.

[0059] Please see the appendix Figure 4 Step 3: Lay a 20mm thick mortar layer on the roof structure floor slab 3 within the floating platform to form a leveling layer 7.

[0060] Please see the appendix Figure 5Step 4: Construct the waterproof layer for the roof structural slab 3. The waterproof layer is then rolled up to wrap around the structural inverted beam 4 and laid on the leveling layer 7 to form the roof waterproof layer 8, ensuring the waterproof performance of the entire roof structure. The specifications of the roof waterproofing are determined according to the building structural design requirements; for example, waterproof membranes or waterproof coatings can be used.

[0061] Please see the appendix Figure 6 Step 5: Pour fine aggregate concrete onto the roof waterproofing layer 8 within the floating platform to form a protective layer 9. The protective layer 9 is 35mm thick and reinforced with internal φ6@200 reinforcement.

[0062] Please see the appendix Figure 7 Step 6: Cover the protective layer 9 with a 50mm thick layer of sound-absorbing cotton, and place 50mm thick sound insulation blocks 101 on the sound-absorbing cotton at 450mm intervals. Place 50mm thick vibration isolation blocks 102 between every two adjacent sound insulation blocks 101, so that the sound insulation blocks 101 and vibration isolation blocks 102 are fully covered on the sound-absorbing cotton.

[0063] Please see the appendix Figure 8 Step 7: Lay a 2mm thick steel plate layer on the sound insulation block 101 and vibration isolation block 102, and lay a 1.5mm thick impermeable membrane on the steel plate layer.

[0064] Please see the appendix Figure 9 Step 8: Pour a 150mm thick reinforced concrete floor slab on the geomembrane to form the installation floor slab 12, completing the construction of the sound insulation and vibration isolation structure. During the pouring of the installation floor slab, the equipment foundation 2 of the large electromechanical equipment 1 is poured and formed simultaneously with the installation floor slab 12.

[0065] Please see the appendix Figure 10 Step 9: Fill the vibration isolation gap between the sound insulation and vibration isolation structure and the structural anti-vibration beam 4 with high-density anti-vibration cork, i.e., anti-vibration material 5, and seal the top of the anti-vibration material 5 with gray mastic, i.e., sealing material 6.

[0066] Please see the appendix Figure 2 Step 10: Install the large electromechanical equipment 1 on the equipment foundation 2.

[0067] By setting up a floating platform between the large electromechanical equipment 1 and the roof structural floor slab 3, the noise and vibration generated by the operation of the large electromechanical equipment 1 are isolated, improving the user comfort of the floors below the equipment floor. When the large electromechanical equipment 1 is running, the noise and vibration are first transmitted to the 150mm thick reinforced concrete floor slab, i.e., the installation floor slab 12, and then isolated by sound insulation cotton, sound insulation blocks 101, and vibration isolation blocks 102, without affecting the roof structural floor slab 3 below. To prevent the vibration of the large electromechanical equipment 1 from causing lateral slippage of the sound insulation and vibration isolation structure, a structural anti-slip beam 4 is set at the edge of the sound insulation and vibration isolation structure as a limiting anti-slip. The structural anti-slip beam and the sound insulation and vibration isolation structure are flexibly connected by vibration-resistant material 5, which can limit the lateral slippage of the large electromechanical equipment 1 and the sound insulation and vibration isolation structure, and prevent the vibration from being transmitted to the anti-slip beam structure 4.

[0068] When constructing within the refuge floor, the sound-insulating and vibration-damping floating platform can be constructed on the floor slab of the refuge floor. Its construction method and structure are the same as those for construction on the roof structure floor slab 3, and will not be described in detail here.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
