Description

Technical Field

[0001] This utility model belongs to the field of building floor sound insulation technology, specifically an auxiliary sound insulation sheet for a nano-modified GPS flexible thermal insulation and sound insulation pad. Background Technology

[0002] There are three traditional methods for sound insulation of building floors. The first is to lay resilient decorative materials such as carpets or solid wood during floor finishing to reduce the sound energy generated when the floor is impacted, thus weakening the floor vibration. The second is to use soundproof suspended ceilings, employing elastic hooks to non-rigidly connect the ceiling to the structural slab, sealing the ceiling layer and sealing any gaps, and laying sound-absorbing materials such as glass wool or rock wool inside. The third method involves placing a resilient vibration-damping and sound-insulating material on the load-bearing layer of the floor slab, and then pouring a 40mm-50mm layer of reinforced fine-aggregate concrete as a protective surface layer. The junction between the surface layer and the wall has corresponding isolation structures, thus ensuring improved sound insulation performance; this is the floating floor technology.

[0003] When using floating floor technology for impact sound insulation of building floors, an elastic material, namely a vertical sound insulation plate, is installed between the floating floor surface of fine aggregate concrete or self-leveling gypsum and the surrounding walls, columns, or vertical pipes penetrating the floor to block sound bridges. The vertical sound insulation plate should be about 30-60mm higher than the floating surface of fine aggregate concrete or self-leveling gypsum, and flush with it after the floor is tiled or floored, to prevent sound bridges from being formed between the finishing layer (especially floor tiles) and the wall, which would weaken or even fail the sound insulation of the floor.

[0004] For vertical sound insulation panels at the base of the wall, if the sound insulation material within the floating floor slab is a roll material, it can be directly flipped up to the base of the wall and fixed with tape, double-sided tape, or a nail gun. If the sound insulation material is a board material, it needs to be cut into strips and fixed to the wall with tape. Regardless of the method, it must be fixed to the wall surface. Then, underfloor heating pipes are laid (in the case of wet underfloor heating), and fine aggregate concrete or self-leveling plaster is poured. If the house is delivered as a bare shell, the vertical sound insulation panels should be exposed about 30-60mm high. If the house is delivered as a fully furnished unit, floor tiles or flooring are laid on the fine aggregate concrete or self-leveling plaster floating surface.

[0005] When a property is handed over as a bare shell, the vertical sound insulation strips are fixed to the wall. However, the subsequent pouring of fine stone concrete or self-leveling gypsum floating surface layer will contaminate the vertical sound insulation strips. Since the subsequent construction of floor tiles, flooring and other finishing layers takes place after the property is handed over to the owner, it will be difficult to hand over the property to the owner because the exposed sound insulation strips (i.e., 30-60mm higher than the fine stone concrete or self-leveling gypsum floating surface layer) will be contaminated. They may even be torn or damaged, affecting the sound insulation of the floor slab.

[0006] When fixing vertical sound insulation panels with tape or double-sided tape, spot bonding can save tape or double-sided tape, while strip bonding provides a stronger bond but consumes more tape or double-sided tape. Both methods are manual and are located at the base of the wall, requiring installers to squat while working, resulting in low efficiency and inconsistent installation quality.

[0007] When using a nail gun to secure vertical sound insulation panels, the nails, being rigid materials, contradict the goal of preventing sound bridges. Too few nails result in insufficient fixation, while too many nails compromise sound insulation, creating a dilemma. Utility Model Content

[0008] To address the problems mentioned in the background art, this utility model provides an auxiliary sound insulation sheet for nano-modified GPS flexible thermal insulation and sound insulation pads. This sheet offers advantages in improving installation efficiency and quality stability. It significantly enhances the installation efficiency and quality stability of vertical sound insulation sheets for integrated nano-modified GPS flexible thermal insulation and sound insulation floor slabs or floating floor slabs. It also provides effective protection against contamination during subsequent fine stone concrete or self-leveling gypsum construction, greatly reducing the difficulty and cost of protecting finished products during subsequent bare-bones handover. Furthermore, it does not generate sound bridges during installation and fixation, thus not reducing the sound insulation effect of the floor slab.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary sound insulation sheet for a nano-modified GPS flexible thermal insulation and sound insulation pad, comprising a sound insulation sheet body, wherein an adhesive layer is fixedly disposed on both the upper and lower sides of the sound insulation sheet body, a first protective film layer is adhered to the outer side of the upper adhesive layer, and a second protective film layer is adhered to the outer side of the lower adhesive layer, an extension area is fixedly disposed on one side of the top surface of the second protective film layer, and another extension area is fixedly disposed on one side of the top surface of the first protective film layer.

[0010] Preferably, the top surface of the first protective film layer has a plurality of perforations, and the perforations are located at the connection between the extension area and the first protective film layer.

[0011] Preferably, a protruding tooth is fixedly provided on one side of the sound insulation sheet body, and a slot is provided on the other side of the sound insulation sheet body, and the protruding tooth and the slot are the same size.

[0012] Preferably, a first reinforcement area is fixedly provided on one side of the top surface of the first protective film, and another first reinforcement area is fixedly provided on one side of the top surface of the second protective film.

[0013] Preferably, a second reinforcement area is fixedly provided on the other side of the top surface of the first protective film layer, and another second reinforcement area is fixedly provided on the other side of the top surface of the second protective film layer.

[0014] Preferably, the sound insulation sheet body is made of polyurethane foam.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses an adhesive layer to bond the sound insulation sheet to the wall. The interlocking of protruding teeth and slots ensures that no part of the sheet is missed during bonding, and that each sheet is installed in the same position, enhancing its aesthetics. This invention significantly improves the installation efficiency and quality stability of vertical sound insulation sheets for nano-modified GPS flexible thermal insulation and soundproofing integrated floor slabs or floating floors. It also provides effective protection against contamination during subsequent fine stone concrete or self-leveling gypsum construction, greatly reducing the difficulty and cost of protecting finished products during subsequent bare-bones handover. Furthermore, no sound bridges are generated during installation, ensuring no reduction in the floor's sound insulation effect. Attached Figure Description

[0022] 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.

[0023] like Figures 1 to 4As shown, this utility model provides an auxiliary sound insulation sheet for a nano-modified GPS flexible thermal insulation and sound insulation pad, including a sound insulation sheet body 1. Adhesive layers 2 are fixedly disposed on both the upper and lower sides of the sound insulation sheet body 1. A first protective film 3 is adhered to the outer side of the upper adhesive layer 2, and a second protective film 4 is adhered to the outer side of the lower adhesive layer 2. An extension area 7 is fixedly disposed on one side of the top surface of the second protective film 4, and another extension area 7 is fixedly disposed on one side of the top surface of the first protective film 3. First, a 20mm thick nano-modified GPS flexible thermal insulation and sound insulation pad is coated with adhesive on one side using an adhesive coating and film coating machine, then covered with PE film or OPP film and pressed firmly. Then, the other side is coated with adhesive and film coated in the same way. Finally, it is cut using a hot wire cutter. The sound insulation strips are cut into strips with a width of 60-150mm, or the width depends on the thickness of the floating floor and the vibration damping and sound insulation material. Then, the first protective film 3 or the second protective film 4 is peeled off through the extension area 7. Then, the sound insulation strip body 1 is pasted to the wall through the adhesive layer 2 on the inside of the first protective film 3 or the second protective film 4. This improves the installation efficiency and quality stability of the vertical sound insulation strips of the nano-modified GPS flexible thermal insulation and sound insulation integrated floor slab or floating floor slab. It provides effective protection against pollution during the subsequent construction of fine stone concrete or self-leveling gypsum, greatly reducing the difficulty and cost of finished product protection for subsequent bare-bones handover. Moreover, no sound bridge is generated during the installation and fixing process, and the sound insulation effect of the floor slab is not reduced.

[0024] Specifically, the top surface of the first protective film 3 has multiple perforations 8, and the perforations 8 are located at the connection between the extension area 7 and the first protective film 3. The first protective film 3 and the second protective film 4 have the same structure. When one of the first protective film 3 or the second protective film 4 is torn off, the other protective film can be used as an anti-pollution protective film. At this time, the extension area 7 needs to be torn off along the position of the perforations 8 to prevent dust from entering the adhesive layer 2 from the position of the extension area 7, which would cause the first protective film 3 or the second protective film 4 to not adhere firmly to the sound insulation sheet body 1.

[0025] Furthermore, a protruding tooth 9 is fixedly provided on one side of the sound insulation sheet body 1, and a slot 10 is provided on the other side of the sound insulation sheet body 1. The protruding tooth 9 and the slot 10 are the same size. Through the mutual cooperation of the protruding tooth 9 and the slot 10, it is ensured that there are no omissions in the sound insulation sheet body 1 during the pasting process. At the same time, it is also ensured that the installation position of each sound insulation sheet body 1 is consistent, thereby increasing its aesthetics.

[0026] Furthermore, a first reinforcement area 5 is fixedly provided on one side of the top surface of the first protective film 3, and another first reinforcement area 5 is fixedly provided on one side of the top surface of the second protective film 4. In order to prevent the film at the position of the protruding teeth 9 from being torn when it is peeled off, which would indirectly lead to an extension of the working time, this area is reinforced by the first reinforcement area 5, thereby ensuring that the film can be peeled off completely.

[0027] It is worth noting that a second reinforcement area 6 is fixedly provided on the other side of the top surface of the first protective film 3, and another second reinforcement area 6 is fixedly provided on the other side of the top surface of the second protective film 4. In order to prevent the film at the slot 10 from being torn when it is peeled off, which would indirectly lead to an extension of the working time, this area is reinforced by the second reinforcement area 6 to ensure that the film can be peeled off completely.

[0028] It is worth noting that the sound insulation sheet body 1 is made of polyurethane foam, which is a lightweight sound insulation material with an open-cell structure that can absorb and disperse sound waves and reduce the propagation of sound. In addition, polyurethane foam also has certain heat insulation properties.

[0029] The sound insulation sheet body 1 is existing technology and will not be described in detail here. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail here. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle:

[0031] When using the auxiliary sound insulation sheet for the nano-modified GPS flexible thermal insulation and sound insulation pad, firstly, the first protective film layer 3 or the second protective film layer 4 is peeled off through the extension area 7. First reinforcement areas 5 and second reinforcement areas 6 are provided on the outer sides of both the first protective film layer 3 and the first reinforcement area 5 to reinforce them and prevent cracking of the first protective film layer 3 or the second protective film layer 4 during the peeling process, which would prolong the working time. Then, the sound insulation sheet body 1 is pasted onto the wall through the adhesive layer 2. Next, the sound insulation sheet body 1 is laid. During this laying process, care must be taken to insert the protruding teeth 9 into the slots 10 to ensure the aesthetics and sealing of the sound insulation sheet body 1, avoiding any omissions that could lead to poor or unsightly sound insulation results. If the fine aggregate concrete or self-leveling gypsum floating surface layer is applied and the unfinished floor is handed over, it does not need to be removed. However, it is necessary to remove the extension area 7 along the position of the tooth hole 8 to prevent dust from entering the adhesive layer 2 from the extension area 7, which could cause the first protective film 3 or the second protective film 4 to not adhere firmly to the sound insulation sheet body 1. This utility model greatly improves the installation efficiency and quality stability of the vertical sound insulation sheet of the nano-modified GPS flexible thermal insulation and sound insulation integrated floor slab or floating floor slab. It provides effective protection against pollution during the subsequent fine aggregate concrete or self-leveling gypsum construction, greatly reduces the difficulty and cost of finished product protection for the subsequent unfinished floor handover, and does not generate sound bridges during the installation and fixing process, thus not reducing the sound insulation effect of the floor slab.
