Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a vibration reduction and noise reduction foundation for electromechanical equipment and an electromechanical equipment room. Background Art

[0002] Mechanical and electrical equipment in equipment rooms generally need to be installed on a vibration and noise reduction foundation, which provides both vibration and noise reduction. Currently, these foundations typically utilize steel springs for vibration reduction. Positioning and installation during construction requires pre-embedded components, which can easily cause the embedded components to be touched during construction, leading to deviations in the final spring installation position and poor vibration and noise reduction effectiveness.

[0003] A Chinese patent application with application number 201920547900.6 discloses a sound-insulating, heat-insulating, and vibration-damping flooring. Specifically, it is disposed above a base floor slab and comprises a first sound-insulating and vibration-damping layer, a second thermal insulation layer, and a third concrete surface layer. The sound-insulating and vibration-damping layer comprises a sound-insulating and vibration-damping pad bonded to the base floor slab with an adhesive. The thermal insulation layer comprises a layer of thermal insulation material bonded to the sound-insulating and vibration-damping layer with an adhesive that is excessively sprinkled with coarse sand. The concrete surface layer comprises two layers: one comprising anti-cracking mortar and the other comprising concrete. The anti-cracking mortar is applied over the thermal insulation layer, and the concrete is applied over the anti-cracking mortar. The sound-insulating and vibration-damping layer of this sound-insulating and vibration-damping flooring is a single flat plate structure, resulting in poor sound insulation and vibration reduction performance, making it difficult to apply to electromechanical equipment for sound insulation and vibration reduction.

[0031] Example 1:

[0032] Figures 1 to 4An embodiment of the vibration reduction and noise reduction foundation for electromechanical equipment of the utility model is shown. The vibration reduction and noise reduction foundation for electromechanical equipment of this embodiment includes a base layer 2, a vibration reduction and noise reduction layer 3, a waterproof layer 4 and a concrete layer 5 laid in sequence from bottom to top. The vibration reduction and noise reduction layer 3 includes multiple elastic supports 31 and glass fiber fillers 32. Each elastic support 31 is arranged at intervals on the base layer 2 and supported on the waterproof layer 4. The glass fiber fillers 32 are filled between each elastic support 31 to form a vibration reduction and noise reduction layer 3.

[0033] On the one hand, the vibration-damping and noise-reducing layer 3 is formed by multiple elastic supports 31 spaced apart on the base layer 2 and supported on the waterproof layer 4. Glass fiber fillers 32 are placed between the elastic supports 31. Compared with existing monolithic flat-plate structures, this layer offers superior sound insulation and vibration reduction, making it suitable for use in electromechanical equipment. On the other hand, the structure, comprising the base layer 2, vibration-damping and noise-reducing layer 3, waterproof layer 4, and concrete layer 5, laid sequentially from bottom to top, not only provides excellent sound insulation and vibration reduction, but also boasts superior waterproofness and support strength.

[0034] Furthermore, in this embodiment, the elastic support 31 is a rubber support, which has a good supporting and vibration reduction effect.

[0035] Furthermore, in this embodiment, the elastic supports 31 are spaced apart horizontally and vertically and are arranged vertically.

[0036] Furthermore, in this embodiment, the bottom end of the elastic support 31 is glued to the base layer 2, which facilitates construction.

[0037] Furthermore, in this embodiment, the glass fiber filler 32 is a glass fiber insulation blanket. The glass fiber insulation blanket has a good physical sound insulation effect and has a function similar to a soundproof wall.

[0038] Furthermore, in this embodiment, the waterproof layer 4 includes a bamboo plywood layer 41 and a waterproof membrane 42 , the bamboo plywood layer 41 is laid on the vibration and noise reduction layer 3 , the waterproof membrane 42 is laid on the bamboo plywood layer 41 , and the concrete layer 5 is arranged on the waterproof layer 4 .

[0039] Furthermore, in this embodiment, the bamboo plywood layer 41 is formed by splicing together a plurality of bamboo plywood pieces.

[0040] Furthermore, in this embodiment, the bamboo plywood sheets are connected by screws 43 and sealed by adhesive tape.

[0041] Furthermore, in this embodiment, the concrete layer 5 is provided with a floating plate.

[0042] Furthermore, in this embodiment, the waterproof membrane 42 is a plastic membrane. The waterproof membrane 42 has good water-proof and anti-seepage performance, is easy to construct, and can prevent leakage during concrete pouring.

[0043] Furthermore, in this embodiment, the side edges of the waterproof membrane 42 are turned up higher than the concrete layer 5 or a side membrane is installed higher than the concrete layer 5 to prevent leakage during concrete pouring.

[0044] Example 2:

[0045] Construction method of the vibration and noise reduction foundation for electromechanical equipment in room 1 of embodiment 1:

[0046] Leveling the base layer 2 and installing the isolation board 7 → installing the elastic support 31 → filling the glass fiber filler 32 → laying the bamboo plywood layer 41 → laying the waterproof membrane 42 → tying the floating board steel bars → pouring the concrete layer 5 → injecting the sealant 8 on the top of the isolation board 7.

[0047] The specific process is as follows:

[0048] 1. Leveling of base layer 2 and installation of isolation board 7

[0049] 1) Check whether there is weak concrete in the equipment room area and whether there are cracks in the ground layer 11. If there are any, they should be chiseled out and repaired with cement slurry of the same strength. After the repair is completed, use chemical curing agent for maintenance.

[0050] 2) Check the flatness of the ground layer 11. The flatness requirement is that the height difference within 1㎡ is ≤5mm. If it cannot be achieved, cement slurry is used to level the ground layer 2.

[0051] 3) After the base layer 2 is leveled, the surveyor measures indoors and places the horizontal point of the floor + 200mm wall, two points on one wall, and marks them with a line with a plumb line. Then, according to the detailed plan layout of the elastic support 31, the center point of the elastic support 31 on the wall is placed, and the vertical and horizontal lines are drawn with the two center points of the wall in the same row as the endpoints. The intersection of the vertical and horizontal lines is the installation point of the elastic support 31. Figure 4 The planar arrangement diagram of the elastic supports 31 is shown. The black dots represent the elastic supports 31 arranged at a center distance of 610 mm and arranged against the wall. The double boxes represent the arrangement of the elastic supports 31 at the bottom of the electromechanical equipment 6.

[0052] 4) After leveling and polishing the installation position of the elastic support 31, perform an elevation check to ensure that the bottom elevation of the elastic support 31 is consistent.

[0053] 5) Clean away dust, sand, mortar lumps and other debris on the surface of the main structure of the floor and walls, and keep them clean, flat and dry.

[0054] 6) Use synthetic rubber adhesive to glue 20mm separating rubber sheets (isolation sheets 7) to the interior side walls 12 or 200mm from the bottom of the columns. Use synthetic rubber adhesive to perform butt joint treatment at the junction of the separating rubber sheets. After gluing, stick a layer of tape on the top of the surrounding separating rubber sheets.

[0055] 2. Install the elastic support 31

[0056] 1) Use an ink fountain to mark the vertical and horizontal positioning points of the elastic support 31 on the ground according to the plan layout of the elastic support 31 between the equipment, locate the installation center point of the elastic support 31, and make a positioning mark 3 cm outside the center point.

[0057] 2) Clean the surface of all the positioning points of the elastic supports 31 with a rag.

[0058] 3) Then use a brush to apply synthetic rubber adhesive with a diameter of 6 cm at the center of the elastic support 31, with a coating thickness of 2 mm, and also apply 2 mm synthetic rubber adhesive to the bottom of the elastic support 31. After the coating is completed, immediately bond it with the center of the elastic support 31 that has been coated, so that the synthetic rubber adhesive is applied one-to-one and the bonding is completed. It is not allowed to apply synthetic rubber adhesive to the centers of multiple elastic supports 31 before applying the synthetic rubber adhesive to the elastic support 31 and installing it.

[0059] 4) After the elastic supports 31 are bonded, calibrate them along a 3cm control line extending 3cm from the center of the supports. After bonding and calibrating the elastic supports 31 across the entire equipment room, immediately seal the equipment room to protect the finished product, as the synthetic rubber adhesive requires 24 hours to reach full strength.

[0060] 3.Filling with glass fiber filler 32

[0061] 1) After the elastic supports 31 reach sufficient bonding strength, they are filled with a 50 mm thick glass fiber insulation blanket (glass fiber filler 32), which provides excellent physical sound insulation, similar to a soundproofing wall. This passive sound insulation, combined with the active sound insulation of the floating slab within the concrete layer 5, further enhances the vibration and sound insulation advantages.

[0062] 2) To ensure the vibration reduction effect of the elastic support 31, it is necessary to drill holes in the glass fiber insulation blanket. Each hole needs to expose the elastic support 31 compactly with a small gap. The glass fiber insulation blanket should be laid in the order from top to bottom and left to right to fill the entire equipment room.

[0063] 3) Mark the opening positions of the glass fiber insulation blanket according to the arrangement of the elastic supports 31, with a hole diameter of 55 mm.

[0064] 4) Lay the fiberglass insulation blankets with holes in order. After filling, check the gaps between the fiberglass insulation blankets and cut the waste materials to fill them up to ensure the sound insulation quality.

[0065] 4. Laying bamboo plywood layer 41

[0066] 1) After laying the fiberglass insulation blanket, lay 18mm thick bamboo plywood on the elastic supports 31 in the order of first the four sides and then the middle. Avoid laying the panels later at the corners of the interior walls, which may cause the panels to be too small to bear the load. When arranging the panels, be careful not to place the elastic supports 31 between the gaps between the two bamboo plywood panels or within 100mm of the gap edge. The joints between the bamboo plywood panels must be ensured to be flat.

[0067] 2) After the bamboo plywood is laid out, seal the gaps between the boards using 5cm wide high-viscosity cloth-based tape. The gaps must be straight and level, and the width between the two bamboo plywood boards must be uniform.

[0068] 3) The bamboo plywood is connected using screws 43 (galvanized steel prefabricated parts). Be careful not to damage the elastic supports 31 when driving screws 43. First, ensure that each of the four board intersections is effectively connected.

[0069] 5. Laying waterproof membrane 42

[0070] 1) After laying the bamboo plywood, remove any debris from it. Lay a 0.5mm thick plastic film (waterproof membrane 42). This waterproof membrane 42 has excellent water-blocking and anti-seepage properties, is easy to install, and prevents leakage during concrete pouring. To avoid two-way overlap, the plastic film is dimensioned to 3000 x 15000 mm.

[0071] 2) Laying requirements: The laying direction of the plastic film should be along the wind direction, and the overlapping length should not be less than 100mm.

[0072] 3) Note: The placement should be accurate and secured with high-viscosity cloth-based tape. The plastic film must be flat, firm, and free of damage. Install the side formwork where there is no rubber sheeting, i.e., where doors and windows are located. The plastic film must be 100mm higher than the concrete layer to prevent leakage during concrete pouring.

[0073] 6. Binding of floating plate reinforcement

[0074] 1) Before arranging the steel bars, cement mortar pads should be arranged first. To avoid contact between the steel bars and the plastic mold, cylindrical pads with a size of 25×φ50mm should be used and arranged at a rate of 4 blocks per 1㎡.

[0075] 2) The floating plate reinforcement is a double-layer bidirectionally arranged φ10@200 steel bar. The spacing of the horse stool reinforcement is arranged at 1000×1000mm. The reinforcement is tied at all intersections. The reinforcement connection in Saudi Arabia can only be connected by lap connection, and the lap length is 40 times the diameter of the steel bar. In order to avoid wasting steel bars, consideration should be given to reducing lap connection when cutting.

[0076] 3) After the floating plate reinforcement (referred to as floating plate) is tied, immediately remove the garbage on the floating plate layer and prepare for pouring concrete.

[0077] 7. Pouring concrete layer 5

[0078] The floating slab concrete uses cast-in-place C25 concrete with a design thickness of 150mm. Its specific construction methods and requirements are consistent with those of general concrete construction. The following requirements should be paid special attention to:

[0079] 1) Concrete should be formed in one go, so the entire floating slab concrete pouring should be carried out continuously. If pauses are necessary, the pause time should be shortened as much as possible.

[0080] 2) To avoid leakage caused by damage to the plastic mold during pouring, the vibration interval and vibration time should be reduced during vibration. The vibration interval should be 30cm and the vibration time should be controlled at 10-15s each time.

[0081] 3) When pouring concrete, a dedicated person should be assigned to regularly observe whether there is any displacement or blockage of bamboo plywood, steel bars, reserved openings, embedded parts, etc. If any problem is found, pouring should be stopped immediately and the poured concrete should be repaired before it begins to set.

[0082] 4) During concrete pouring, the position of embedded components must be checked promptly. Work may only be performed on the poured concrete after it reaches 1.2 MPa. The concrete surface should be smoothed with a concrete trowel before initial setting. Chemical curing should be performed within 12 hours of pouring.

[0083] 8. Inject sealant 8 on the top of the isolation board 7

[0084] 1) After the concrete pouring is completed, remove the concrete slag and garbage on the top of the edge rubber sheet, tear off the top separation tape, and cut off the excess plastic film.

[0085] 2) Mix the polysulfide polymer and curing agent in a ratio of 5:1, and stir with a flat-blade stirrer and a slow electric drill. After stirring for 2 minutes, scrape off the colloid adhering to the edge of the container and merge it with the colloid at the bottom of the container and continue stirring for 2 minutes to complete the stirring.

[0086] 3) After stirring, use a syringe to inject the mixed sealant into the area to be sealed, ensuring that the injection is even and completely covered.

[0087] 4) After curing is complete, remove excess sealant 8 and clean the work area.
