Description

Technical Field

[0001] This utility model relates to the field of vibration isolation and noise reduction technology, and in particular to a vibration isolation pad laying structure based on a floating platform and the floating platform. Background Technology

[0002] A floating platform consists of an elastic layer and a floating layer. The floating layer is made of reinforced concrete, while the elastic layer is composed of elastic support components. Essentially, a floating platform is an active vibration isolation method that isolates the sound source from the building. By using vibration-damping rubber pads and sound-absorbing rock wool to separate the floating platform from the equipment foundation, the energy consumption of vibration and noise transmission is increased, thereby optimizing vibration reduction and noise reduction effects.

[0003] The current method for laying vibration-damping pads on floating platforms involves marking lines on the ground according to the construction drawings, pre-setting the positions for the vibration-damping pads, and then using a small amount of all-purpose adhesive to attach and fix the pads to their positions one by one. This traditional method of laying vibration-damping pads is cumbersome and inefficient.

[0004] Based on this, this application provides a vibration isolation pad laying structure that is simple to construct and has high laying efficiency, thus solving the above problems. Utility Model Content

[0005] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model provides a vibration isolation rubber pad laying structure and a floating platform based on a floating platform, so as to improve the construction efficiency and construction quality of the vibration isolation rubber pad.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] In a first aspect, a vibration-damping pad laying structure based on a floating platform is provided, comprising several pad bodies laid in a rectangular array on a floor leveling layer and several positioning strips embedded in the leveling layer. A boss is provided in the middle of the upper surface of each positioning strip, and multiple screw holes are provided at equal intervals along the length of the boss. Positioning pins for positioning the pad bodies are screwed into the screw holes. The length of the positioning pins is less than the thickness of the pad bodies. At least at its center, the pad body has a through hole that matches the positioning pin. The through hole is inserted into the positioning pin. The bottom of the pad body has a groove with a width equal to the width of the boss. The groove of each pad body is aligned with the boss and inserted into the positioning pin.

[0008] In some alternative implementations, the upper surface of the positioning strip is disposed on the same horizontal plane as the surface of the leveling layer.

[0009] In some alternative implementations, the positioning strip has mounting rods at at least at both ends, the mounting rods being embedded in the floor slab.

[0010] In some alternative implementations, the spacing between two adjacent positioning strips is equal to the installation spacing of the rubber pad body.

[0011] In some alternative implementations, the spacing between two adjacent screw holes is equal to 0.5 times the maximum installation distance of the rubber pad body.

[0012] The second invention provides a floating platform, comprising a curb on the floor slab, an edge sealant on the inner side of the curb, a leveling layer arranged from bottom to top within the curb, an elastic layer composed of several vibration-damping pads and sound-absorbing rock wool arranged between the vibration-damping pads, a galvanized steel plate layer, a waterproof adhesive paper layer, and a concrete surface layer, as well as an elastic sealant arranged between the curb and the concrete surface layer; wherein the vibration-damping pads are laid on the leveling layer using the above-mentioned vibration-damping pad laying structure.

[0013] In some optional embodiments, the anti-rebound wall is provided with embedded rebars in the floor slab, the leveling layer is a C30 concrete leveling layer, and the vibration isolation pad is a CDM-60 vibration isolation pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model enables rapid insertion and positioning of the rubber pad body by pre-embedding positioning strips on the leveling layer. This effectively improves the laying efficiency and quality, and solves the problems of cumbersome operation and low efficiency of the traditional method of laying the pad body by first laying out the lines and then pasting them one by one with glue.

[0016] 2. Setting the upper surface of the positioning strip flush with the surface of the leveling layer can provide an elevation reference during the construction of the leveling layer. Attached Figure Description

[0029] Example 1

[0030] As attached Figure 1 and attached Figure 2 As shown, this embodiment provides a vibration isolation pad laying structure based on a floating platform, including several pad bodies 4.1 laid in a rectangular array on the floor leveling layer 3 and several positioning strips 10 pre-embedded in the leveling layer 3 for positioning and installing the pad bodies 4.1.

[0031] As attached Figure 4 As shown, the upper surface of the positioning strip 10 in this embodiment is provided with a boss 10.1 in the middle. Multiple screw holes 10.2 are provided at equal intervals along the length direction of the boss. A positioning pin 11 for positioning the rubber pad body is screwed into the screw hole. The length of the positioning pin 11 is less than the thickness of the rubber pad body 4.1.

[0032] As attached Figure 3 As shown, the rubber pad body 4.1 has at least a through hole 4.2 at its center position that matches the positioning pin. The through hole 4.2 is inserted into the positioning pin 11, and the bottom of the rubber pad body 4.1 has a groove 4.3 with a width equal to the width of the boss 10.1.

[0033] In specific implementation, according to the laying requirements of vibration isolation pads: the vibration isolation pads near the curb should be laid 50mm away from the curb, the spacing of the vibration isolation pads in the non-equipment placement area should be 400mm, and the spacing of the vibration isolation pads in the equipment placement area should be 200mm. Therefore, the distance between two adjacent positioning strips is 200mm or 400mm (i.e., the spacing between positioning strips outside the equipment positioning area is 400mm, while the spacing between positioning strips within the equipment positioning area is 200mm), and the spacing between two adjacent screw holes is 200mm. For the positioning strip area within the equipment positioning area, a pin is installed in each screw hole. For the positioning strip area outside the equipment positioning area, a pin is installed every other screw hole. Simultaneously, ensure that the distance between the pins at both ends of the positioning strip and the curb is 50mm (according to the design drawings, the size of the curb should meet the requirement that the vibration damping pad is 50mm away from the curb after it is laid as required). After pre-embedding the positioning strips in the leveling layer, the pad body is determined by the position of the pins. Each pad body can be directly inserted into the positioning pin with its groove and protrusion aligned. This method of laying vibration damping pads effectively improves laying efficiency and quality.

[0034] Preferably, to ensure the installation stability of the positioning strip, as shown in the attached... Figure 2 As shown, in this embodiment, the positioning strip 10 is provided with mounting rods 10.3 at least at both ends, and the mounting rods 10.3 are embedded in the floor slab.

[0035] Example 2

[0036] Based on Embodiment 1, this embodiment further sets the upper surface of the positioning strip 10 and the surface of the leveling layer 3 on the same horizontal plane. This design can provide an elevation reference during the construction of the leveling layer.

[0037] Application examples

[0038] As attached Figure 1 and attached Figure 2 As shown, a floating platform is provided, comprising a curb 1, an edge adhesive 2, a leveling layer 3 arranged sequentially from bottom to top within the curb, an elastic layer composed of several vibration-damping pads 4 and sound-absorbing rock wool 5 disposed between the vibration-damping pads, a galvanized steel plate layer 6, a waterproof adhesive paper layer 7, a concrete surface layer 8, and an elastic sealant 9 disposed between the curb and the concrete surface layer. The specific method is as follows:

[0039] The construction of the upstand on the floor slab follows existing conventional techniques and will not be elaborated upon here. It is preferable to embed rebar into the floor slab within the upstand to ensure a stronger connection. After the upstand is constructed, an edge sealant is applied to the inner wall of the upstand. A 10mm thick elastic adhesive sheet is preferred, and the sealant should extend approximately 200mm above the concrete surface.

[0040] Based on the designed spacing of the vibration isolation pads for equipment placement and non-equipment placement, and in conjunction with the elevation of the leveling layer, the positioning strip with pins is fixed to the floor slab (the pins are set on the positioning strip according to the method in Embodiment 1); then, a C30 concrete leveling layer is poured, and after the leveling layer has solidified, the bottom groove of the vibration isolation pad is aligned with the protrusion on the positioning strip and inserted into the positioning pin. In this embodiment, the vibration isolation pad can be a 50*50*50mm CDM-60 vibration isolation pad.

[0041] The gaps between the vibration-damping rubber pads are filled with 50mm thick sound-absorbing rock wool. Then, galvanized steel plates with a thickness of not less than 2mm are laid on the sound-absorbing rock wool in a certain order. The steel plates are fixed by spot welding, and the spot welding positions avoid the placement points of the vibration-damping rubber pads. The steel plates are welded with T-shaped splices. After the steel plates are laid, a layer of waterproof adhesive paper is laid on them. The waterproof adhesive paper is a self-adhesive modified bitumen waterproof membrane. Finally, the concrete surface layer is constructed.

[0042] After the concrete surface layer is completed, cut the edge sealant and seal the space between the curb and the concrete surface layer with elastic sealant.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
