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 density means more noise from people. Therefore, the current "Building Technical Regulations" requires that in new or additional buildings of townhouses and complex houses, the floors used to separate the upper and lower floors must have a certain sound insulation effect to avoid mutual interference.

As mentioned above, sound insulation can be further divided into noise reduction and shock absorption. In order to effectively absorb shocks, cement mortar, shock-absorbing materials, cement mortar, plates and tiles are generally stacked in sequence on the concrete layer used as the floor slab to prepare a floor structure with shock-absorbing function. However, the above-mentioned floor has a complicated structure. Specifically, in order to stably install the shock-absorbing material in the floor structure, the operator needs to lay cement mortar before and after installing the shock-absorbing material. That is to say, just laying the cement mortar, shock-absorbing material and cement mortar in the floor structure will cost a lot of construction time and labor. If the laying procedure is complicated or the technology is not good, it may cause the construction quality to be uneven, thus reducing the shock absorption effect. Therefore, how to design a floor structure with a simple structure and excellent shock absorption effect has become an urgent problem to be solved in the art.

The decoration layer is arranged on the shock absorbing layer.

The floor structure of the present application forms a polymer shock-absorbing layer with high support and excellent shock-absorbing effect by directly mixing shock-absorbing materials into cement mortar. Compared with the prior art, the floor structure of the present application has a simple structure, is easy to operate, can greatly reduce the construction cost, and can be effectively applied in various buildings.

Please refer to FIG. 1 , which is a schematic diagram of a floor structure according to an embodiment of the present application. As shown in the figure, the floor structure 1 includes a concrete layer 10 , a polymer shock absorbing layer 11 and a decoration layer 12 . The polymer shock absorbing layer 11 is disposed on the concrete layer 10, and the polymer shock absorbing layer 11 is formed by drying the mixture. Further, the mixture includes cement, sand and shock absorbing material 110, and the shock absorbing material has a density between 20 and 1200 kg/m ³ . The decoration layer 12 is disposed on the shock absorbing layer. By absorbing the shock by the shock absorbing material 110 disposed in the polymer shock absorbing layer 11 , the floor structure 1 of the present application can have an excellent shock absorbing effect. Besides, the structure of the floor structure 1 of the present application is simple, which helps to simplify the construction process, and is applied in various buildings. 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. It is worth mentioning that the concrete layer 10 of the present application may also include a shock absorbing material 110 such as the polymer shock absorbing layer 11 to further enhance the shock absorbing effect. The specific description of the shock absorbing material 110 can be referred to below.

A polymer shock absorbing layer 11 is provided on the concrete layer 10 . In the present application, the polymer shock absorbing layer 11 is formed by drying a mixture comprising cement mortar 111 and shock absorbing material 110 stirred, but it is not limited to the above-mentioned materials. The cement mortar 111 is made of water, silt, and cement, and mixed with additives such as surfactants, such as superplasticizers. For example, high-efficiency plasticizers can contain sulfonic acid groups or acrylic acid groups to act as cement water reducers to reduce the consistency of cement mortar. In this way, the mixture obtained by mixing the above components has fluidity and is easy to apply. It is worth mentioning that, the polymer shock absorbing layer 11 of the present application does not limit the mixing step, which can be adjusted according to the actual situation. For example, when the operator is preparing the polymer shock absorbing layer 11 , the operator can first prepare the cement mortar 111 in a specific proportion, and then put the shock absorbing material 110 into the cement mortar 111 and stir evenly. Alternatively, the operator can also input water, sediment, cement and the shock absorbing material 110 at the same time to prepare the polymer shock absorbing layer 11 (ie, the mixture) that has not yet been cured.

In some embodiments, the mixture may further comprise lime. Specifically, by mixing lime into the cement mortar 111 to form a mixed mortar, the mixture can be made to have more excellent adhesiveness. A mixture with excellent adhesion properties can be used to bond the two plies of the floor structure 1 . For example, when the floor structure 1 also includes a waterproof layer, a fireproof layer or other types of functional layers, the operator can mix lime into the material of the mixture, and use the mixture mixed with lime as an interlayer adhesive, so as to achieve the At the same time shock absorption, adhesion and high support effect. Therefore, the quality of the polymer shock absorbing layer 11 can also be effectively improved by using various auxiliary agents or dispersants known to those skilled in the art.

In some embodiments, the shock absorbing material 110 comprises plastic, rubber, fiber, or any combination thereof. Specifically, the above-mentioned materials all have excellent modulus of elasticity, that is, the above-mentioned materials can reduce vibration through a large amount of deformation, elasticity, absorption or storage of energy. Therefore, when the polymer material layer includes the shock absorbing material 110, a part or all of the external vibration (eg, sound wave, shock wave, impact, etc.) will be absorbed by the polymer material, thereby achieving excellent shock absorbing effect.

For example, the shock absorbing material 110 may be thermoplastic elastomers (Thermoplastic elastomers, TPE), such as: thermoplastic polyurethane (Thermoplastic polyurethane, TPU), polyolefin elastomers (Thermoplastic olefinic Elastomer, TPE), or thermosetting (cross-linked) rubber (Vulcanized Elastomers), polystyrene hydrocarbon elastomer (Styrene/Butadiene Rubber, SBR), polyester elastomer (Thermoplastic polyester elastomer, TPEE) or polyamide elastomer (Thermoplastic Polyamide Elastomer, TPA/TPE-A), etc. .

For example, the shock absorbing material 110 can also be a polymer foam, such as: polyurethane foam (PU foam), polystyrene foam (Styrofoam, PS foam) or polyolefin foam (polyolefin foam) ), ethylene-vinylacetate copolymer foam (ethylene-vinylacetate, EVA foam), polyvinyl chloride foam (PVC foam), etc. Due to the large number of two-phase elastic interface spaces and air spaces formed by the pores, the transmission of external vibrations (such as sound waves, shock waves, impacts, etc.) and/or heat energy can be hindered (for example, absorbed or not. regularly diverge). In this way, under the premise of shock absorption, the polymer shock absorbing layer 11 can also have more excellent sound insulation and heat insulation effects.

In some embodiments, the weight percentage of the shock absorbing material 110 is 5% to 75%. For example, the weight percentage of the shock absorbing material 110 may be 5%, 15%, 25%, 35%, 45%, 55%, 65%, 75%, or any range of the above values. Wherein, the operator can adjust the weight percentage of the shock absorbing material 110 according to the requirements of the floor slab. For example, when the floor slab needs a higher shock absorption effect, the operator can add more shock absorption materials 110 . Alternatively, when the floor slab requires high support, the operator can increase the proportion of the cement mortar 111 .

In some embodiments, the density of shock absorbing material 110 is between 20 and 1200 kg/m ³ . For example, the density of shock absorbing material 110 may be 20 kg/m ³ , 50 kg/m ³ , 100 kg/m ³ , 200 kg/m ³ , 300 kg/m ³ , 400 kg/m ³ , 500 kg/ m ³ , 600 kg/m ³ , 700 kg/m ³ , 800 kg/m ³ , 900 kg/m ³ , 1000 kg/m ³ , 1100 kg/m ³ , 1200 kg/m ³ , or any of the above values scope.

In some embodiments, the shock absorbing material 110 comprises a plurality of particles, the plurality of particles are non-spherical irregular shaped shapes and foam density (pore size). For example, the plurality of particles may be cone-shaped (eg, triangular pyramid, quadrangular pyramid), irregular block (eg, polyhedron), or similar to wave-absorbing blocks. With the complex and irregular shape, the plurality of particles can better inter-lock with the cement mortar 111 . In addition, the irregular shape and foam holes also help to improve the noise reduction effect. In some embodiments, the plurality of particles may also have different sizes, shapes, or surface roughnesses, so as to further enhance the noise reduction effect. For example, a part of the plurality of particles may be plate-shaped or flake-shaped, and another part of the plurality of particles may be granular or block-shaped.

In some embodiments, the plurality of particles have a density between 20 and 1200 kg/m ³ , and different particles may have different densities. For example, the plurality of particles include first particles, second particles, and third particles. The density of the first particles may be 200 kg/m ³ , the density of the second particles may be 400 kg/m ³ , and the density of the third particles may be 1200 kg/m ³ . By having different densities, different particles can produce different shock absorption effects, thereby suppressing vibrations more effectively. It is worth mentioning that the above description is only an example, and the present application is not limited thereto.

As shown in the figure, in some embodiments, the polymer shock absorbing layer 11 includes a plurality of polymer shock absorbing sublayers, and the weight percentages of the shock absorbing materials 110 in the plurality of polymer shock absorbing sublayers are different from each other. For example, the polymer shock absorbing layer 11 includes a first polymer shock absorbing sublayer 11a, a second polymer shock absorbing sublayer 11b and a third polymer shock absorbing sublayer 11c stacked in sequence, and the first polymer shock absorbing sublayer 11a Closest to the concrete layer 10 , the third polymer shock absorbing sub-layer 11 c is farthest away from the concrete layer 10 . The weight percentage of the shock absorbing material 110 in the first polymer shock absorbing sublayer 11a is 15%, the weight percentage of the shock absorbing material 110 in the second polymer shock absorbing sublayer 11b is 35%, and the third polymer shock absorbing sublayer The weight percentage of the shock absorbing material 110 in 11c is 55%. By arranging the third polymer shock-absorbing sub-layer 11c containing the most shock-absorbing material 110 at a position far away from the concrete layer 10 (ie, the position closest to the occupants), it can effectively absorb the shock generated by the occupants in the first time. Vibrations (or, sounds made by occupants). Further, by arranging the first polymer shock-absorbing sub-layer 11a containing the least shock-absorbing material 110 at a position close to the concrete layer 10 (ie, the position closest to the floor), it can effectively support the upper second height The molecular shock absorbing sub-layer 11b and the third polymer shock absorbing sub-layer 11c. It is worth mentioning that the above descriptions are only examples, and the present application is not limited thereto. In some embodiments, the plurality of polymer shock absorbing sub-layers may be two layers, four layers, or more than four layers. In some embodiments, the weight percentage of the shock absorbing material 110 between each layer may not gradually increase or decrease, but may be arranged in a high-low cross manner. For example, four polymer shock absorbing sub-layers with weight percentages of 35%, 55%, 35% and 55% are stacked in sequence.

In some embodiments, decorative layer 12 may comprise ceramic tile, quartz tile, slate or wood flooring, or any combination thereof.

The board layer 13 can be a single-layer structure, and any of the above-mentioned boards can be selected according to the actual use conditions. Alternatively, the board layer 13 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 13 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, the fireproof board can also use phosphorus-based, antimony-based, aluminum-magnesium-based or their oxides, or hydroxides to replace halogen elements, so as to comply with environmental regulations while being flame-resistant.
