Description

Technical Field

[0001] This utility model relates to the field of floor slabs, and in particular to a floating floor slab structure. Background Technology

[0002] Noise pollution is a serious form of environmental pollution. With the continuous improvement of social material and cultural standards, noise pollution is intensifying, severely impacting the physical and mental health of the general public. Among numerous noise complaints, the impact noise from floors and the mutual influence of airborne noise have seriously affected neighborly relations and the normal use of functional spaces, especially in high-noise equipment rooms. This necessitates floor vibration and sound insulation in high-noise spaces such as KTVs and cinemas, and in spaces with high requirements for impact noise reduction (dance spaces, etc.). The primary solution for floor impact noise and airborne noise is a floating floor structure. Commonly available structures include spring-loaded floating structures, thick rubber block-split floating structures, and thin vibration-damping pad-covered floating structures. Most of these floating structures suffer from the following problems: ① Spring-loaded floating structures have poor vibration stability, large floor slab weight, require high installation height, and are expensive; ② Thick rubber block-laid floating structures have large floor slab weight and require high installation height; ③ Thin vibration isolation pad-covered floating structures are only suitable for spaces with small loads, and have limited effect on improving airborne sound insulation and floor impact sound, failing to meet the requirements for spaces with high sound insulation and high impact sound improvement. Therefore, it is essential to design a double-channel hollow damping vibration isolation and sound insulation floating floor structure to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems and shortcomings, and to provide a double-channel hollow damping vibration isolation and sound insulation floor floating structure. This double-channel hollow damping vibration isolation and sound insulation floor floating structure has the advantages of good vibration stability, small weight, low installation height, good overall cost performance, and large load capacity. It has a very significant effect on improving air sound insulation and floor impact sound, and can meet the requirements of high sound insulation and high impact sound improvement in space.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A floating structure for a double-channel hollow damping vibration isolation and sound insulation floor slab is characterized by comprising a concave-convex plate, a supporting plate, several hollow vibration isolation and sound insulation blocks, and several damping vibration isolation strips.

The upper end of each hollow vibration isolation and sound insulation block rests on the bottom of the lower groove, and the lower end of each damping vibration isolation strip rests in the upper groove. The supporting plate overlaps the upper end of each damping vibration isolation strip.

[0006] Preferably, the embossed plate body includes an embossed steel plate and a first damping layer, wherein the first damping layer is laid on the upper surface of the embossed steel plate.

[0007] Preferably, the concave-convex steel plate includes several Z-shaped steel plates and several horizontal steel plates.

[0008] Preferably, the support plate includes a support steel plate and a second damping layer, the second damping layer being laid on the top surface of the support steel plate.

[0009] Preferably, the hollow vibration isolation and sound insulation block is a natural rubber block, a nitrile rubber block, a polyurethane rubber block, or a silicone rubber block, and the hollow vibration isolation and sound insulation block has at least one vertical through hole; the through hole is rectangular, circular, or elliptical; the hollow vibration isolation and sound insulation block is rectangular, circular, or elliptical.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, this utility model will be described in detail with reference to the schematic diagram. When describing the embodiments of this utility model in detail, for ease of explanation, the cross-sectional views of the device structure will be partially enlarged without adhering to the general scale. Moreover, the schematic diagram is only an example and should not limit the scope of protection of this utility model.

[0036] like Figures 1 to 3 As shown, the floating structure of a double-channel hollow damping vibration isolation and sound insulation floor slab of this utility model includes a concave-convex plate 1, a supporting plate 2, a plurality of hollow vibration isolation and sound insulation blocks 3, and a plurality of damping vibration isolation strips 4. The concave-convex plate 1 is arranged horizontally, and the recesses on the upper and lower surfaces of the concave-convex plate 1 respectively form an upper groove 11 and a lower groove 12. The upper end of each hollow vibration isolation and sound insulation block 3 rests on the bottom of the lower groove 12, and the lower end of each damping vibration isolation strip 4 is placed in the upper groove 11. The supporting plate 2 overlaps the upper end of each damping vibration isolation strip 4.

[0037] In this double-channel hollow damping vibration isolation and sound insulation floating floor structure, a concave-convex plate 1, several hollow vibration isolation and sound insulation blocks 3, and several damping vibration isolation strips 4 are used. The upper ends of the hollow vibration isolation and sound insulation blocks 3 and the lower ends of the damping vibration isolation strips 4 are respectively placed in the lower groove 12 and upper groove 11 on the concave-convex plate 1. This not only reduces the overall height but also creates a double-channel hollow damping vibration isolation and sound insulation effect, resulting in excellent vibration stability and facilitating load-bearing capacity. The use of hollow vibration isolation and sound insulation blocks 3 not only controls weight but also increases compression, thereby improving vibration isolation efficiency and achieving a superior overall cost performance. The supporting plate 2 provides a reliable laying surface for the floor or concrete layer, which not only facilitates laying but also helps to achieve a stable and reliable vibration isolation and sound insulation effect. Therefore, this double-channel hollow damping vibration isolation and sound insulation floating floor structure has advantages such as good vibration stability, small weight, low installation height, superior overall cost performance, and large load capacity. It has a very significant effect on improving airborne sound insulation and floor impact sound, and can meet the requirements of high sound insulation and high impact sound improvement in space.

[0038] This double-channel hollow damping vibration isolation and sound insulation floating floor structure can be used in equipment vibration isolation, high-noise space floor vibration isolation and sound insulation, and floor vibration isolation with high impact sound requirements, and its application range is relatively wide.

[0039] like Figure 2 and Figure 3 As shown, the convex-concave plate 1 includes a convex-concave steel plate 13 and a first damping layer 14, which is laid on the upper surface of the convex-concave steel plate 13. This not only gives the convex-concave plate 1 high structural strength but also suppresses thin-plate resonance and coincidence effect of the steel plate, which enhances airborne sound insulation performance and thus helps to further improve the reliability and applicability of the double-channel hollow damping vibration isolation and sound insulation floor floating structure.

[0040] The thickness of the concave-convex steel plate 13 and the first damping layer 14 can be designed according to actual needs. The first damping layer 14 is a damping felt or a coating. The first damping layer 14 is fixed by self-adhesion, glue bonding or vulcanization bonding, which can well meet the needs of actual manufacturing and use.

[0041] like Figure 2As shown, the convex-concave steel plate 13 includes several U-shaped steel plates 131 and several horizontal steel plates 132. The U-shaped steel plates 131 are arranged horizontally side-by-side, and the horizontal steel plates 132 are spaced apart from each U-shaped steel plate 131, with the horizontal steel plates 132 overlapping the ends of corresponding U-shaped steel plates 131. The upper groove 11 is formed between adjacent U-shaped steel plates 131, and the lower groove 12 is formed by the inner grooves of the U-shaped steel plates 131. This not only makes the packaging, storage, and transportation of the convex-concave steel plate 13 very convenient, but also ensures very convenient installation, thereby helping to further improve the applicability of this double-layer hollow damping vibration isolation and sound insulation floor floating structure.

[0042] The end of the horizontal steel plate 132 is welded and fixed to the end of the zigzag steel plate 131, which ensures a very stable and reliable connection. In the actual manufacturing process, the convex and concave steel plate 13 can still be integrally formed from the steel plate.

[0043] like Figure 2 and Figure 3 As shown, the supporting plate 2 includes a supporting steel plate 21 and a second damping layer 22, which is laid on the top surface of the supporting steel plate 21. This not only gives the supporting plate 2 high structural strength but also suppresses thin-plate resonance and coincidence effect of the steel plate, which enhances damping performance and thus helps to further improve the reliability and applicability of the double-channel hollow damping vibration isolation and sound insulation floor floating structure.

[0044] The supporting plate 2 is mainly used to support cement mortar or concrete structures. The thickness of the supporting steel plate 21 and the second damping layer 22 can be designed according to actual needs. The second damping layer 22 can be a self-adhesive damping felt, PVC film or waterproof membrane with damping effect. The second damping layer 22 is fixed by self-adhesion, glue bonding or vulcanization bonding.

[0045] like Figures 2 to 7 As shown, the hollow vibration isolation and sound insulation block 3 is made of natural rubber, nitrile rubber, polyurethane rubber, or silicone rubber. At least one vertical through-hole 31 is provided on the hollow vibration isolation and sound insulation block 3; the through-hole 31 is rectangular, circular, or elliptical; the hollow vibration isolation and sound insulation block 3 is rectangular, circular, or elliptical. This design gives the hollow vibration isolation and sound insulation block 3 a very stable and reliable structure, thereby helping to further improve its vibration isolation and sound insulation performance, and further improving the reliability and applicability of the double-channel hollow damping vibration isolation and sound insulation floor slab floating structure.

[0046] like Figure 2 , Figure 3 and Figure 8As shown, the damping vibration isolation strip 4 comprises, from bottom to top, a lower elastic soft vibration isolation pad 41, a lower rigid strip 42, a lower damping layer 43, an upper elastic soft vibration isolation pad 44, an upper rigid strip 45, and an upper damping layer 46, stacked together sequentially. This damping vibration isolation strip 4 can achieve an extremely stable and reliable damping and vibration isolation effect, thereby helping to further improve the reliability and applicability of this double-channel hollow damping vibration isolation and sound insulation floor slab floating structure.

[0047] The number of layers, thickness, and width of the damping vibration isolation strip 4 are designed according to on-site requirements; the lower rigid strip 42 and the upper rigid strip 45 are cut from templates, inorganic material boards, organic material boards, metal plates, etc.; the lower elastic soft vibration isolation pad 41 and the upper elastic soft vibration isolation pad 44 are elastic lightweight material pads such as rubber, silicone, foamed polyurethane, and foamed rubber; the lower damping layer 43 and the upper damping layer 46 are damping felt or damping spray coating material layers; this can well meet the needs of actual manufacturing and use.

[0048] like Figures 1 to 3 As shown, the space between adjacent hollow vibration isolation and sound insulation blocks 3 is filled with lower sound-absorbing cotton 5. Filling with lower sound-absorbing cotton 5 can achieve dual-channel sound wave reflection and absorption, control the weight of the floating floor slab, and increase the overall sound insulation of the floating floor slab, thereby helping to further improve the reliability and applicability of this double-channel hollow damping vibration isolation and sound insulation floating floor slab structure.

[0049] like Figures 1 to 3 As shown, upper sound-absorbing cotton 6 is filled between adjacent damping vibration isolation strips 4. Filling with upper sound-absorbing cotton 6 can achieve dual-channel sound wave reflection and absorption, control the weight of the floating floor slab, and increase the overall sound insulation of the floating floor slab, thereby helping to further improve the reliability and applicability of this double-channel hollow damping vibration isolation and sound insulation floating floor slab structure.

[0050] The lower sound-absorbing cotton 5 and the upper sound-absorbing cotton 6 are made of sound-absorbing materials such as rock wool, glass wool, and organic environmentally friendly cotton, which can achieve good sound absorption effect.

[0051] like Figures 1 to 3 As shown, a double-layer sandwich vibration isolation plate 7 is laid on the top surface of the end of the concave-convex plate 1, and the end of the supporting plate 2 overlaps on the double-layer sandwich vibration isolation plate 7. This not only provides a stable structure at the end but also achieves good vibration isolation, thereby helping to further improve the reliability and applicability of the double-channel hollow damping vibration isolation and sound insulation floor floating structure.

[0052] like Figure 9As shown, the double-layer sandwich vibration isolation plate 7 includes a lower elastic soft plate 71, a metal plate 72, and an upper elastic soft plate 73 stacked together from bottom to top; the lower elastic soft plate 71 and the upper elastic soft plate 73 are made of elastic lightweight materials such as rubber, silicone, polyurethane foam, or foamed rubber; the metal plate 72 is a steel plate or other metal plate 72. This double-layer sandwich vibration isolation plate 7 not only has an extremely stable and reliable structure but also provides excellent vibration isolation.

[0053] like Figures 1 to 3 As shown, elastic lightweight vibration isolation pads 8 are provided on the side walls of the concave-convex plate 1. This can separate the wall from the concave-convex plate 1, thus enabling the double-channel hollow damping vibration isolation and sound insulation floor floating structure to have better vibration isolation performance, thereby helping to further improve the reliability and applicability of the double-channel hollow damping vibration isolation and sound insulation floor floating structure.

[0054] like Figures 1 to 3 As shown, the elastic lightweight vibration isolation pad 8 can be a single layer or multiple layers. A flexible sealing element 9 is provided on the top of the elastic lightweight vibration isolation pad 8. This facilitates reliable vibration isolation and sound insulation performance.

[0055] like Figures 1 to 3 As shown, a concrete layer 10 is laid on the top surface of the supporting plate 2. The concrete layer 10 needs to be reinforced to resist cracking and increase strength. The thickness of the concrete layer 10 is greater than or equal to 40mm to meet the compression requirements of the damping vibration isolation strip 4. A countersunk protrusion 101 is provided at the end of the concrete layer 10. The thickness of the countersunk protrusion 101 is greater than or equal to 100mm, mainly used for wall sound insulation and load bearing of decorative materials.

[0056] The specific steps for installing this type of double-channel hollow damping vibration isolation and sound insulation floating floor structure are as follows:

[0057] First, check that the ground, site environment, and other process requirements meet the installation requirements;

[0058] like Figure 10 As shown, the elastic lightweight vibration isolation pad 8 can be installed and glued to the corner of the wall 100.

[0059] like Figure 11 As shown, hollow vibration isolation and sound insulation blocks 3 and lower sound-absorbing cotton 5 are installed on the floor slab 200; the hollow vibration isolation and sound insulation blocks 3 can be arranged more densely on the floor slab 200 near the wall 100.

[0060] like Figure 12As shown in the figure, install the concave-convex plate body 1 and the flexible seal 9; first install the concave-convex steel plate 13, then install the first damping layer 14 on the concave-convex steel plate 13, and finally use the flexible seal 9 to flexibly sound-insulate and seal the gap between the concave-convex steel plate 13 and the wall 100. The concave-convex steel plate 13 can be made into a finished product and welded on-site, or it can be made into a "U" shape and a flat steel plate and welded on-site;

[0061] As Figure 13 shown in the figure, install the elastic lightweight vibration isolation pad 8, which can be bonded to the wall with glue, and make the elastic lightweight vibration isolation pad 8 here above the flexible seal 9;

[0062] As Figure 14 shown in the figure, install the damping vibration isolation strip 4 and the double-layer sandwich vibration isolation plate 7; the damping vibration isolation strip 4 and the double-layer sandwich vibration isolation plate 7 can be prefabricated;

[0064] As Figure 16 shown in the figure, install the supporting plate body 2; first install the supporting steel plate 21, and lay the second damping layer 22 on the supporting steel plate 21; when the supporting steel plate 21 is spliced by multiple steel plates, the adjacent steel plates are fully welded;

[0065] As Figures 1 to 3 、 Figure 17 shown in the figure, pour the concrete layer 10 and the counterfort convex platform 101 on the supporting plate body 2; the decorative surface layer 30 can also be laid on the concrete layer 10.

[0066] This patent relates to the field of floor vibration isolation and sound insulation in building engineering technology. Compared with the traditional floating floor structure, the utility model has the following advantages: the hollow vibration isolation and sound insulation block 3 and the damping vibration isolation strip 4 are embedded and combined up and down, optimizing the load distribution and being more conducive to vibration isolation; the sound insulation effect is better under the same surface load, and the newly added weight of the floor can be reduced under the same sound insulation effect; under the condition of the same decorative height, the vibration isolation effect is better and the surface weight is smaller.

However, the above description is only a preferred embodiment of this utility model, and this utility model can be implemented in many other ways different from those described herein.
