Description

Technical Field

[0001] This application relates to the field of floor slab paving, and in particular to a sound insulation floor slab paving structure. Background Technology

[0002] Floor slabs are load-bearing components that horizontally divide the space of a building and are crucial to its structure. Floor slab paving structure refers to the structural system comprised of all layers from the load-bearing floor slab to the final floor finish; it is a composite structural system including structural layers, intermediate functional layers, and finishing layers.

[0003] Currently, existing sound insulation paving structures for floor slabs typically use inorganic thermal insulation mortar and polyester sound insulation pads as the main materials to ensure the sound insulation and thermal insulation effects of the floor slabs. Among them, the polyester sound insulation pads are usually only laid on the top layer of the floor slab, and they are prone to displacement due to the external forces during subsequent laying, which in turn affects the sound insulation effect of the floor slab. Utility Model Content

[0004] To ensure the sound insulation effect of the floor slab, this application provides a sound insulation paving structure for the floor slab.

[0005] The sound insulation paving structure for floor slabs provided in this application adopts the following technical solution:

[0006] A sound insulation floor paving structure includes a functional layer and a decorative layer sequentially disposed on the top of the floor slab. The functional layer includes a sound insulation and vibration damping pad, an extruded polystyrene insulation layer, a vacuum-metallized polyester film layer, and a leveling layer sequentially disposed. The sound insulation and vibration damping pad includes a floor slab laying part and a wall laying part. The floor slab laying part is laid on the floor slab, and the wall laying part is fixedly connected to the floor slab laying part and extends to the wall. The extruded polystyrene insulation layer is disposed on the top of the floor slab laying part.

[0007] By adopting the above technical solution, the sound insulation and vibration damping pad extends to the wall installation section, allowing the extruded polystyrene insulation layer to limit the position of the sound insulation and vibration damping pad through the pressure between it and the wall after installation. This helps to ensure the stability of the sound insulation and vibration damping pad's position, making it less likely for the pad to shift due to external forces during subsequent installation. This helps to ensure the sound insulation effect of the floor slab. At the same time, the vacuum-aluminized polyester film layer helps to reflect heat upwards, improving the thermal insulation performance of the floor slab.

[0008] Optionally, a wall insulation layer is provided on top of the vacuum-aluminized polyester film layer, the wall insulation layer including an extruded polystyrene board attached to the wall; the leveling layer includes a C20 fine stone concrete layer, the C20 fine stone concrete layer is provided on top of the vacuum-aluminized polyester film layer, a heating pipe is provided inside the C20 fine stone concrete layer, and the top of the wall insulation layer is flush with the top of the C20 fine stone concrete layer.

[0009] By adopting the above technical solutions, the installation of heating pipes covered with fine stone concrete facilitates uniform heat conduction to the heating pipes and helps ensure the stability of the ground structure. The installation of extruded polystyrene boards along the walls helps reduce heat loss through the walls and further ensures the thermal insulation performance of the laid structure.

[0010] Optionally, the thickness of the C20 fine aggregate concrete layer is between 45mm and 55mm, the thickness of the extruded polystyrene board is between 18mm and 22mm, and the distance between the top of the heating pipe and the top of the C20 fine aggregate concrete layer is between 28mm and 32mm.

[0011] By adopting the above technical solution, the C20 fine stone concrete layer can effectively protect the heating pipe while ensuring its heat conduction performance.

[0012] Optionally, the thickness of the sound insulation and vibration damping pad is between 5mm and 18mm, and the thickness of the extruded polystyrene insulation layer is between 18mm and 22mm.

[0013] By adopting the above technical solutions, it is beneficial to ensure both the thermal insulation performance and the sound insulation effect of the paving structure.

[0014] Optionally, the sound insulation and vibration damping pad includes several spliced ​​pad bodies, and two adjacent spliced ​​pad bodies are connected by a connecting component. The connecting component includes a first connecting part and a second connecting part. The first connecting part is fixedly installed on one of the spliced ​​pad bodies, and the second connecting part is fixedly installed on the other adjacent spliced ​​pad body. The first connecting part and the second connecting part are engaged.

[0015] By adopting the above technical solution, the sound insulation and vibration damping pads composed of multiple spliced ​​pads are easier to apply force to achieve sequential installation of individual spliced ​​pads during the laying and installation process. The installation accuracy and flexibility are greater. At the same time, the first and second connecting parts between each spliced ​​pad play a limiting role between adjacent spliced ​​pads, which helps to ensure the stability of the position of the sound insulation and vibration damping pad after it is laid.

[0016] Optionally, both the first connecting portion and the second connecting portion have raised or recessed textures on the side that is close to each other.

[0017] By adopting the above technical solution, the embossed texture further ensures the stability of the position of the first connecting part and the second connecting part when they are engaged, which is conducive to further ensuring the stability of the position of the two adjacent splicing pads.

[0018] Optionally, each of the splicing pads includes a floor slab splicing part and a wall splicing part fixedly connected to the floor slab splicing part. The floor slab splicing parts are spliced ​​together to form a floor slab laying part, and the wall splicing parts are spliced ​​together to form a wall splicing part. An L-shaped connecting member is provided on the side of the splicing pad near the wall. The connecting member includes a horizontal part and a vertical part. The floor slab splicing part is fixedly installed on the horizontal part, and the wall splicing part is fixedly installed on the vertical part.

[0019] By adopting the above technical solution, the connecting components serve as positioning indicators during the laying of the splicing pads, facilitating the rapid installation of the splicing elevators to the required positions and ensuring the laying efficiency of the splicing pads, i.e., the sound insulation and vibration damping pads.

[0020] Optionally, a rubber gasket is provided between the vertical part of the connecting member and the wall.

[0021] By adopting the above technical solution, the setting of rubber gaskets helps to further ensure the stability of the position of the connecting components after installation, and facilitates further absorption of vibration energy, thus fully ensuring the sound insulation effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. After the extruded polystyrene board insulation layer is laid, the pressure between it and the wall helps to limit the position of the sound insulation and vibration damping pad, thereby helping to ensure the stability of the sound insulation and vibration damping pad. This makes it less likely that the sound insulation and vibration damping pad will shift due to external forces during subsequent laying, which helps to ensure the sound insulation effect of the floor slab.

[0024] 2. The installation of fine stone concrete covering the insulation pipe facilitates uniform heat conduction to the heating pipe and helps ensure the stability of the ground structure. The installation of extruded polystyrene board along the wall helps reduce heat loss through the wall and further ensures the insulation performance of the structure.

[0025] 3. Sound insulation and vibration damping pads made up of multiple spliced ​​pads are easier to apply force during installation, allowing for the sequential installation of individual spliced ​​pads, resulting in greater installation accuracy and flexibility. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] Example 1.

[0033] This application discloses a sound insulation paving structure for floor slabs. (Refer to...) Figure 1 The sound insulation paving structure of the floor slab includes a functional layer 1 and a decorative layer 2 arranged sequentially from bottom to top on the top of the floor slab. The functional layer 1 includes a sound insulation and vibration damping pad 11, an extruded polystyrene insulation layer 12, a vacuum-metallized polyester film layer 13, and a leveling layer 14 arranged sequentially from bottom to top.

[0034] Specifically, the thickness of the sound insulation and vibration damping pad 11 is between 5mm and 18mm. Specifically, when used for tile finishes in interior entryways, living rooms, dining rooms, and connecting corridors, the thickness of the sound insulation and vibration damping pad is selected as 16mm. When used for wood floor finishes in interior master bedrooms, bedrooms, and walk-in closets, the thickness of the sound insulation and vibration damping pad is selected as 5mm, to ensure the sound insulation effect of the sound insulation and vibration damping pad 11 in different application scenarios. The sound insulation and vibration damping pad 11 includes a floor slab laying part 111 and a wall laying part 112. The floor slab laying part 111 is laid on the floor slab, and the wall laying part 112 is integrally fixedly connected to the floor slab laying part 111 and extends to the wall to further ensure the sound insulation effect of the sound insulation and vibration damping pad 11.

[0035] Continue to refer to Figure 1The extruded polystyrene (XPS) insulation layer 12 is laid on top of the floor slab 111. The thickness of the XPS insulation layer 12 is between 18mm and 22mm. In this embodiment, the thickness of the XPS insulation layer 12 is selected as 20mm to ensure the insulation effect of the XPS insulation layer 12. After the XPS insulation layer 12 is laid, it acts as a limiter on the position of the sound insulation and vibration damping pad 11 by pressing against the wall, thereby helping to ensure the stability of the position of the sound insulation and vibration damping pad 11. This makes it less likely that the sound insulation and vibration damping pad 11 will shift due to external forces during subsequent laying, thus facilitating more stable sound insulation by the sound insulation and vibration damping pad 11.

[0036] A vacuum-metallized polyester film layer 13 is laid on top of the extruded polystyrene (XPS) insulation layer 12 to facilitate upward reflection of heat and further ensure the thermal insulation performance of the floor slab. A wall insulation layer 131 is provided on top of the vacuum-metallized polyester film layer 13. The wall insulation layer 131 includes an XPS board attached to the wall, wherein the thickness of the XPS board is between 18 mm and 22 mm. In this embodiment, the thickness of the XPS board is selected as 20 mm.

[0037] Continue to refer to Figure 1 The leveling layer 14 includes a C20 fine stone concrete layer 141, which is poured and smoothed on top of the vacuum-aluminized polyester film layer 13. The C20 fine stone concrete layer 141 is located within the area enclosed by the wall insulation layer 131. The thickness of the C20 fine stone concrete layer 141 is between 45mm and 55mm. In this embodiment, the thickness of the C20 fine stone concrete layer 141 is selected as 50mm. The top of the wall insulation layer 131 is flush with the top of the C20 fine stone concrete layer 141. That is, the height of the extruded polystyrene board is the same as the thickness of the C20 fine stone concrete layer 141, which is also 50mm. This further reduces heat loss through the wall by the cooperation between the top of the wall insulation layer 131 and the C20 fine stone concrete layer 141, thus ensuring the insulation performance of the laid structure. A heating pipe 3 is installed inside the C20 fine stone concrete layer 141. The distance between the heating pipe 3 and the top of the C20 fine stone concrete layer 141 is between 28mm and 32mm. In this embodiment, it is specifically selected as 30mm to cover and protect the heating pipe 3 and ensure the heat conduction effect of the heating pipe 3.

[0038] Continue to refer to Figure 1The finishing layer 2 includes, from bottom to top, a mortar bonding layer 21, a plain cement adhesive layer 22, and a tile layer 23. Specifically, the mortar bonding layer 21 is a dry-hardened mortar composed of cement and sand mixed in a 1:3 volume ratio, with cement powder laid on its surface to provide a solid and smooth transition layer. In this embodiment, the thickness of the mortar bonding layer 21 is 24 mm. The thickness of the plain cement adhesive layer 22 is 5 mm in this embodiment to ensure strong adhesion to the tiles. The thickness of the tile layer 23 is 10 mm in this embodiment, and a matching color grout is used to ensure the aesthetic appeal of the tile layer 23 after installation.

[0039] The implementation principle of a floor slab sound insulation paving structure in this application embodiment is as follows: After the paving structure is laid as a whole, the sound insulation and vibration damping pad 11 extends to the wall paving part 112 of the wall, so that the extruded polystyrene insulation layer 12, after being laid, plays a limiting role in the position of the sound insulation and vibration damping pad 11 through the pressure between it and the wall. This helps to ensure the stability of the position of the sound insulation and vibration damping pad 11, making it less likely that the sound insulation and vibration damping pad 11 will be displaced by external forces during subsequent laying, which helps to ensure the sound insulation effect of the floor slab.

[0040] Example 2.

[0041] Reference Figure 2 and Figure 3 The main difference between this embodiment and Embodiment 1 is that the sound insulation and vibration damping pad 11 in this embodiment includes several spliced ​​pad bodies 113. Adjacent spliced ​​pad bodies 113 are connected by a connecting component. Specifically, one of the spliced ​​pad bodies 113 is designated as the first pad body 1131, and the other pad body adjacent to the first pad body 1131 is designated as the second pad body 1132. The connecting assembly includes a first connecting part 1133 and a second connecting part 1134. The first connecting part 1133 is integrally fixedly installed on the side of the first pad 1131 facing the second pad 1132, and the second connecting part 1134 is integrally fixedly installed on the side of the adjacent second pad 1132 facing the second pad 1132. The ends of the first connecting part 1133 and the second connecting part 1134 that are close to each other are provided with hooks 1135 that engage with each other. The engagement of the two hooks 1135 between the first connecting part 1133 and the second connecting part 1134 stably achieves a stable limiting effect on the first pad 1131 and the second pad 1132, that is, the two adjacent spliced ​​pads 113. The sides of the two hooks 1135 that engage are provided with concave and convex textures 1136 to further ensure the stability of the first connecting part 1133 and the second connecting part 1134 after engagement, and ultimately ensure the stability of the position of the sound insulation and vibration damping pad 11 after it is laid.

[0042] Each splicing pad 113 includes a floor slab splicing part 1137 and a wall splicing part 1138 fixedly connected to the floor slab splicing part 1137. After the splicing pads 113 are spliced ​​together, the floor slab splicing parts 1137 of each splicing pad 113 are spliced ​​together to form a floor slab laying part 111, and the wall splicing parts 1138 are spliced ​​together to form a wall laying part 112.

[0043] Continue to refer to Figure 2 and Figure 3 To facilitate the installation of individual splicing pads 113, each splicing pad 113 is provided with a connecting member 4 on the side near the wall. In this embodiment, the connecting member 4 is specifically selected as a steel component. The connecting member 4 is L-shaped and includes a horizontal part 41 and a vertical part 42. The floor slab splicing part 1137 is bonded and fixed to the top of the horizontal part 41, and the wall splicing part 1138 is bonded and fixed to the side of the vertical part 42 facing the horizontal part 41. This allows the connecting member 4 to serve as a positioning indicator for the installation of individual splicing pads 113, facilitating the quick installation of the splicing pads 113 to the designated position. The vertical part 42 of the connecting member 4 is fixed to the wall side by screws that pass through the splicing pad 113 and itself. A rubber gasket 421 is bonded and fixed to the side of the vertical part 42 facing the wall to further ensure the stability of the position of the connecting member 4 after installation, and to further absorb vibration energy, ensuring the sound insulation effect of the pavement structure.

[0044] The implementation principle of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
