Description

floor structure

The present application relates to the technical field of building structures, in particular to a floor structure.

With the change of economic structure, social structure and spatial structure, the population begins to concentrate in the city. Rising population means more noise from people. Therefore, the current "Building Technical Regulations" requires that in new or additional buildings of townhouses and complex houses, the floor used to separate the upper and lower floors must have a certain sound insulation effect.

In the prior art, generally, sound insulation materials, cement mortar, boards and tiles are sequentially stacked on a concrete layer as a floor slab to prepare a floor structure with sound insulation function. In order not to damage the sound insulation material during construction, operators usually mix cement, water and sand in an open area to form ready-mixed cement mortar. However, in this way, the delivery route of the ready-mixed cement mortar is delayed, and the fluidity of the ready-mixed cement mortar becomes low (gradually solidified), resulting in poor construction quality, which is time-consuming and labor-intensive. If the passage space is small, the back-and-forth handling of cement mortar will also cause great trouble to the operators. Therefore, how to effectively improve the operation efficiency and maintain the integrity and quality of the floor structure has become an urgent problem to be solved in the art.

The embodiments of the present application provide a floor structure, which solves the problems of poor construction quality, time-consuming and labor-consuming that the current floor structure needs to stir cement mortar in an open area.

The protective layer is arranged on the sound insulation layer. The cement mortar layer is arranged on the protective layer.

The floor structure of the present application protects the sound insulation layer by the protective layer laid on the sound insulation layer, so that the operator can stir the cement mortar on the sound insulation layer through the protective layer. In this way, the operator does not need additional working space for mixing, and can also avoid damage to the sound insulation layer during the mixing process. Therefore, the floor structure manufactured according to the technical content of the present application can effectively improve the work efficiency and maintain the integrity and quality of the floor structure.

Please refer to FIG. 1 , which is a schematic diagram of a floor structure 1 according to an embodiment of the present application. As shown in the figure, the floor structure 1 includes a concrete layer 10 , a sound insulation layer 11 , a protective layer 12 and a cement mortar layer 13 . The sound insulation layer 11 is arranged on the concrete layer 10 . The protective layer 12 is disposed on the sound insulation layer 11 . The cement mortar layer 13 is arranged on the protective layer 12 . By disposing the protective layer 12 on the sound insulation layer 11, the present application realizes a floor structure 1 with excellent application efficiency, so as to solve the problems of the prior art. In the following, each layer in the floor structure 1 will be described in detail to make the technical features of the present application more comprehensible and clear.

In some embodiments, the concrete layer 10 may be a floor-to-floor floor structure (ie, a floor) that is used to carry various functional floor panels located thereon.

In some embodiments, the sound insulating layer 11 may comprise a flexible material such as rubber, plastic, elastomer or fabric, or any combination thereof. For example, the plastic may comprise polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), any combination thereof, or the like. The elastomer may comprise polyurethane (PU), ethylene vinyl acetate (EVA), ethylene propylene rubber (EPDM), any combination thereof, or the like. The fibrous article may comprise natural fibers, rayon fibers, synthetic fibers, nonwovens, fabrics, or any combination thereof or the like. It is worth mentioning that the above-mentioned materials are only examples, and the present application is not limited thereto. All sound insulation materials known to those with ordinary knowledge in the technical field can be applied to the present application.

In some embodiments, the sound insulation layer 11 with better sound insulation effect can also be obtained by changing the porosity, density or ratio of the above-mentioned materials according to actual use conditions. Alternatively, the porous material can also be used directly to prepare the sound insulating layer 11 . Porous material refers to a material that contains many pores. The transfer of sound and/or thermal energy can be impeded (eg, absorbed or irregularly diffused) by the large number of two-phase interfaces formed by the porosity. For example, the porous material can be organic fiber material, inorganic fiber material (glass wool, rock wool, mineral wool), foam (Styrofoam, PE foam), phenolic resin, urea-formaldehyde resin (Urea /Formaldehyde resin) or a combination of polyurethane (PU), but not limited to this. In other embodiments, a sound insulation layer 11 with a high damping coefficient can also be selected, so that the entire floor structure 1 becomes an over-damping system, thereby avoiding the occurrence of resonance phenomenon.

In some embodiments, the sound insulation layer 11 can be measured according to CNS15160-8:2009 (Acoustics-Insulation Measurement of Buildings and Building Components-Laboratory Measurement of Impact Sound Reduction of Heavy Standard Floor Surface Materials), And obtained the sound insulation material declared by CNS8465-2:2007 (Acoustics - Sound insulation of buildings and building components - Impact sound insulation). Taking volume reduction as an example, the materials selected for the sound insulation layer 11 are mainly those that can reduce the volume by 17dB to 21dB, and the material that can reduce the volume by 21dB is preferred.

The protective layer 12 serves to protect the sound insulation layer 11 from damage. In some embodiments, the operator first sets the sound insulation layer 11 on the concrete layer 10 , and then lays the protective layer 12 on the sound insulation layer 11 . Next, the operator directly mixes materials on the protective layer 12 to prepare cement mortar, and lays the prepared cement mortar on the protective layer 12 . Compared with the prior art that needs to transport the cement slurry, by laying the protective layer 12 on the sound insulation layer 11 , the operator can directly stir the cement slurry on the spot without worrying about damaging the sound insulation layer 11 . In this case, in addition to greatly reducing the operation time, it can also save the manpower for handling the cement mortar, and also reduce the delay in the delivery process of the ready-mixed cement mortar, causing the risk of cement mortar solidification and increasing the difficulty of construction. It is worth mentioning that the above steps are only examples, and the concrete layer 10 , the sound insulation layer 11 , and the protective layer 12 of the present application are not limited to be stacked in sequence. In other embodiments, the sound insulation layer 11 and the protective layer 12 may also be connected (eg, adhered, bonded) first, and then simultaneously disposed (eg, laid) on the concrete layer 10 .

In some embodiments, the protective layer 12 comprises sandpaper (release paper), aluminum foil, PET film (Mylar), fabric, non-woven fabric, or any combination thereof, and serves to protect the sound insulation layer 11 from damage. It is worth mentioning that the above-mentioned materials of the protective layer 12 are only examples, and those with ordinary knowledge in the art can select different materials as the protective layer 12 according to the field operation conditions, the composition of the cement mortar, the material of the sound insulation layer 11 and other conditions. For example, when the sound insulation layer 11 has high hardness and high wear resistance, those skilled in the art can choose a thinner protective layer 12 to reduce the thickness of the floor structure 1 . On the other hand, when the sound insulation layer 11 has low wear resistance, or the amount of cement mortar to be stirred is large, a person with ordinary knowledge in the art can lay a thicker or higher-strength protective layer 12 for sound insulation layer 11 to avoid damage to the sound insulation layer 11 . That is, what the present application essentially conceives is how to effectively improve construction efficiency, and should not be limited to the various materials exemplified above.

In some embodiments, the cement mortar layer 13 is formed by stirring water, cement and sand, but not limited thereto. Those with ordinary knowledge in the art can add different components to the cement mortar layer 13 according to requirements, so that the cement mortar layer 13 has a composite effect. For example, the cement mortar layer 13 may contain materials such as fireproof material, waterproof material and the like.

In some embodiments, the floor structure 1 further comprises a board layer 14 disposed on the cement mortar layer 13 . The board layer 14 may comprise cement fiber board, fireproof board, calcium silicate board, gypsum board, dense floor (medium density fiber board), wood core board, artificial plywood, vertical board or plywood, or any combination thereof. The board layer 14 may be a single-layer structure, and any of the above-mentioned boards may be selected according to actual use conditions. Alternatively, the board layer 14 can also be a multi-layer structure, and various functional layers are stacked in sequence to achieve multi-functional purposes. For example, the board layer 14 may include a fireproof board and a calcium silicate board. Wherein, the fireproof board may be composed of a halogen-containing fireproof material or a fire-resistant material. Alternatively, phosphorus-based, antimony-based or hydroxide-based halogen elements can also be used in the fireproof board to meet environmental regulations while being flame-resistant. Calcium silicate board is a lightweight board made of quartz powder, diatomite, cement, lime, pulp, glass fiber and other materials through pulping, molding, steam curing, surface sanding (matting) and other procedures. Excellent moisture resistance, sound insulation, insect resistance and high durability. That is, by combining different types of materials, the fireproof board can have the advantages of the above-mentioned materials at the same time.

In some embodiments, the floor structure 1 further includes a decorative layer 15 , which may be disposed on the board layer 14 . It is worth mentioning that when the floor structure 1 does not include the board layer 14 , the decorative layer 15 can also be directly disposed on the cement mortar layer 13 . Decorative layer 15 may comprise ceramic tiles, quartz tiles, slate or wood floors, or any combination thereof. The decoration layer 15 can choose different materials according to the application. For example, in some embodiments, the decorative layer 15 may comprise quartz tiles to provide a hard, wear-resistant effect. Alternatively, in some embodiments, the decorative layer 15 may comprise a wood floor to provide a comfortable, aesthetically pleasing effect. Alternatively, the decorative layer 15 may also be a composite material, such as Stone Plastic Composite. Further, the stone-plastic floor can include an anti-UV layer, a wear-resistant layer, a vinyl coating, a core layer and a backing layer stacked in sequence, so as to have good waterproof, stable, wood-like appearance and mute effect. It is worth mentioning that the present application is not limited to the above-mentioned materials, and all materials of the decoration layer 15 known to those skilled in the art can be used in the present application.

In some embodiments, the floor structure 1 may further include an adhesive layer 16 . The adhesive layer 16 is disposed between the sound insulation layer 11 and the concrete layer 10 and is used for bonding the sound insulation layer 11 and the concrete layer 10 . The adhesive layer 16 may be a single layer or a multi-layer film. For example, if the thermal expansion coefficients of the sound insulation layer 11 and the concrete layer 10 are greatly different, the adhesive layer 16 may include a first adhesive layer 16 and a second adhesive layer 16 , and the first adhesive layer 16 and the second adhesive layer 16 The two adhesive layers 16 may respectively have different thermal expansion coefficients. More specifically, the sound insulation layer 11 is first pasted with the first adhesive layer 16 having a similar thermal expansion coefficient, while the concrete layer 10 is pasted with the second adhesive layer 16 having a similar thermal expansion coefficient, and finally the first adhesive layer 16 and the second adhesive layer 16 are pasted. The two adhesive layers 16 are adhered to each other. By arranging multilayer films with different thermal expansion coefficients, the bonding between the sound insulation layer 11 and the concrete layer 10 can be more stable. However, the above-mentioned layers are only examples, and the present application is not limited thereto. In other embodiments, the adhesive layer 16 may be a multilayer film with more than 2 layers, for example, the adhesive layer 16 may be a multilayer film with more than 3 layers, 4 layers, 5 layers or more than 6 layers. In addition, the above-mentioned coefficient of thermal expansion is only an example, and the present application is not limited thereto. In other embodiments, the adhesive layer 16 may also include a plurality of film layers with different surface tensions, materials or physical properties to match different sound insulation layers 11 and concrete layers 10 .

In some embodiments, the material of the adhesive layer 16 may comprise resin. That is, the adhesive layer 16 may be an adhesive composed of a resin material. For example, the resin adhesive may include phenolics, urea/Formaldehyde resin, melamine/Formaldehyde resin, polyvinyl acetate resin, polyacrylic resin (eg, Poly (methyl methacrylate) copolymer), polyurethane (PU), epoxy resins (Epoxy resins), polysiloxanes (polysiloxanes) or any combination thereof. However, the above-mentioned types of adhesives are merely examples, and the present application is not limited thereto. Any material known to one of ordinary skill in the art can be used in this application. For example, commercially available super glues (including cyanoacrylates) can be used for the adhesive layer 16 of the present application. Alternatively, in some specific cases, light-curable resins (UV-curable resins, containing PU or epoxy resin) can also be used for the adhesive layer 16 of the present application.

To sum up, the floor structure of the present application protects the sound insulation layer by the protective layer laid on the sound insulation layer, so that the operator can stir the cement mortar on the sound insulation layer. In this way, the operator does not need additional working space for mixing, and can also avoid damage to the sound insulation layer during the mixing process. Therefore, the floor structure manufactured according to the technical content of the present application can effectively improve the work efficiency and maintain the integrity and quality of the floor structure.
