Description

Technical Field

[0001] The present invention relates to a floor structure, in particular to a sound-insulating floor provided with a heating system. Background Art

[0002] At present, modern commercial and residential buildings require a light self-weight, so the thickness of the structural slab is getting thinner and thinner. Generally, the thickness of the floor slab is 100-150 mm. The sound insulation effect of the floor slab with this thickness fails to meet the requirements of the regulations on noise and sound insulation in the "Code for Residential Building" GB50368-2005. Floor slab sound insulation is one of the important factors for ensuring the sound environment of residences. With the continuous improvement of the people's requirements for the quality of residences, people have higher and higher requirements for the sound insulation effect of living and working places. The existing floor slab structure simply cannot meet people's requirements for the sound insulation effect.

[0003] Moreover, with the continuous improvement of people's living quality, the heating system is no longer exclusive to the northern regions. Many southern families will also choose to install a floor heating system during the decoration process. However, at present, many families with installed heating systems generally have the problems of unsatisfactory heating temperature and uneven heat distribution. In severe cases, water seepage also occurs. Summary of the Invention

[0004] The purpose of the present invention is to provide a sound-insulating floor provided with a heating system. This floor slab structure has good shock absorption and sound insulation effects, thus meeting people's requirements for the sound insulation effect. Moreover, this floor slab structure also solves the problems of unsatisfactory heating temperature and uneven heat distribution of the heating system.

[0005] The technical solution of the present invention: A sound-insulating floor provided with a heating system includes a floor slab, and a shock absorption and sound insulation layer, a water and electricity installation layer, a floor heating installation layer, and a building decoration surface layer are sequentially arranged on the floor slab from bottom to top; a wood board with a thickness ≥ 12 mm is arranged on the top surface of the shock absorption and sound insulation layer, and a PE film is arranged on the top surface of the wood board; the water and electricity installation layer includes a main water and electricity installation layer at the bottom and a leveling layer at the top; the floor heating installation layer includes a heat preservation layer at the bottom, a reflective film is covered on the heat preservation layer, a floor heating coil is laid on the reflective film, and wire meshes are laid both above and below the floor heating coil.

[0006] In the foregoing sound-insulating floor provided with a heating system, a first waterproof layer is arranged between the floor slab and the shock absorption and sound insulation layer, and a second waterproof layer is arranged between the shock absorption and sound insulation layer and the water and electricity installation layer.

[0007] In the foregoing sound-insulating floor provided with a heating system, a floor heating coil is installed in the floor heating installation layer, and leveling blocks are scattered on the ground between the floor heating coils, and the top surface of the leveling blocks is higher than the top surface of the floor heating coil.

[0008] In the above-mentioned sound-insulating floor slab provided with a heating system, the overlapping length of adjacent joints of the PE film should be ≥ 100 mm, and the overlapping part is fixed and sealed with tape.

[0009] In the above-mentioned sound-insulating floor slab provided with a heating system, when the thickness of the water and electricity installation layer is greater than 35 mm, a steel mesh with double-layer reinforcement is arranged inside it.

[0010] In the above-mentioned sound-insulating floor slab provided with a heating system, the shock-absorbing and sound-insulating layer includes scattered soft shock-absorbing support blocks, and rock wool is filled between the shock-absorbing support blocks.

[0011] In the above-mentioned sound-insulating floor slab provided with a heating system, the shock-absorbing support blocks are arranged in a dot matrix as a whole; the shock-absorbing support blocks are made of a sound-absorbing material with a sponge or sponge-like structure; the thickness of the rock wool (22) and the shock-absorbing support blocks is 50 mm.

[0012] In the above-mentioned sound-insulating floor slab provided with a heating system, the first waterproof layer is a flexible waterproof layer or a rigid waterproof layer, and the four sides of the first waterproof layer are turned up as a whole and lapped with the bottom of the turned-up part of the second waterproof layer. The four sides of the second waterproof layer are turned up above the building decorative surface layer, and the overall upward extension length is ≥ 500 mm.

[0013] In the above-mentioned sound-insulating floor slab provided with a heating system, the building decorative surface layer includes floor tiles on the top surface and an adhesive layer on the bottom surface.

[0014] Advantages of the present invention: Compared with the prior art, the present invention forms a structure similar to a sound bridge through the floor slab, the shock-absorbing and sound-insulating layer, and the upper structure of the shock-absorbing and sound-insulating layer, thereby blocking the sound on the top surface of the overall floor slab and absorbing the impact vibration on the top surface of the overall floor slab. In the entire structure, the shock-absorbing and sound-insulating layer can be used to reduce / eliminate / block the transmission of noise; by arranging a wood-based board on the shock-absorbing and sound-insulating layer, different degrees of point depressions on the shock-absorbing and sound-insulating layer during the construction process can be avoided, ensuring that the sound bridge effect of the shock-absorbing and sound-insulating layer will not be affected; and by arranging a PE film, it can further ensure that when the cement mortar of the water and electricity installation layer is poured, water or other liquids will not leak into the shock-absorbing and sound-insulating layer to damage the sound bridge structure. By arranging the first waterproof layer, the last waterproof effect can be formed, and by the second waterproof layer, the surface waterproof and water storage prevention effect can be achieved, thereby solving the problems of water storage and moisture on the floors of kitchens, toilets, etc., and avoiding the weakening or even damage of the shock-absorbing and sound-insulating layer caused by water leakage. During the installation of the floor heating coil, by arranging leveling blocks, during the backfilling of concrete, the top surface of the concrete is flush with the top surface of the leveling blocks, ensuring that the thickness of the floor heating installation layer is consistent, and the heating temperature of the thermal insulation floor heating is relatively uniform. By arranging a leveling layer on the top of the water and electricity installation layer, the thickness of the later-constructed floor heating installation layer and the building decorative surface layer is the same, which can ensure the flatness of the ground and make the heating temperature more reasonable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present invention will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0019] Embodiment 1: A sound-insulating floor slab provided with a heating system, as Figure 1As shown in the figure, it includes a floor slab 1, on which a shock-absorbing and sound-insulating layer 2, a water and electricity installation layer 3, a floor heating installation layer 4, and a building decoration surface layer 5 are successively arranged from bottom to top. Among them, the floor slab 1, the shock-absorbing and sound-insulating layer 2, and the upper structure of the shock-absorbing and sound-insulating layer 2 form a structure similar to a sound bridge, thereby blocking the sound on the top surface of the floor slab 1 and absorbing the impact vibration on the top surface of the floor slab 1.

[0020] Because both the rock wool 22 and the shock-absorbing support blocks 21 in the shock-absorbing and sound-insulating layer 2 are soft materials, during construction, regardless of whether it is the standing of construction workers or the pouring of concrete, different degrees of point depressions will occur. The point depressions will cause uneven depressions of different degrees, resulting in uneven compression amounts and greatly reducing the sound bridge effect, thus affecting the final sound bridge effect. To solve this problem, a wood board 8 with a thickness ≥ 12 mm is set on the top surface of the shock-absorbing and sound-insulating layer 2, and a PE film is set on the top surface of the wood board 31.

[0021] The thickness of the wood board 31 should not be less than 12 mm. When the closing board is less than 12 mm, the trampling of personnel and the pouring of concrete in the water and electricity installation layer 3 are very likely to damage the wood board 8, resulting in the waste of the wood board 8, the rock wool 22, and the shock-absorbing support blocks 21, or many situations such as the cracking and breaking of the wood board 8 under the gravity of the water and electricity installation layer 3, leading to the failure of the overall sound insulation plan.

[0022] The size of the wood board 31 is 300 mm - 400 mm, and its bottom end just supports on the shock-absorbing support blocks 21, avoiding the wood board 31 pressing on the rock wool 22 and affecting the sound insulation effect of the rock wool 22.

[0023] Because the water and electricity installation layer 3 mostly uses cheap and easily obtainable ordinary mortar materials, when the water and electricity installation layer 3 is cement mortar, the excess liquid in the cement mortar during the pouring process seeps downward under the action of gravity and flows to the bottom layer. The liquid will be absorbed by the bottom layer or volatilize in all directions. The rock wool 22, the shock-absorbing support blocks 21, and the wood board 8 in the shock-absorbing and sound-insulating layer 2 are relatively afraid of liquid. The wood board 8 is prone to rot and deteriorate after absorbing water, while the rock wool 22 and the shock-absorbing support blocks 21 are prone to caking after absorbing liquid, affecting the sound insulation effect. Therefore, a certain waterproof treatment should be done on the top surface of the wood board 8, so a PE film is set on the top surface of the wood board 8.

[0024] The overlapping parts of the PE films are completely sealed with transparent tape. Because the PE film is in the form of a coil and it is impossible to completely cover the entire room, living room, etc. in one piece, the overlapping parts of the PE films should be not less than 100 mm, and the overlapping parts should be fixed and sealed with transparent tape. At the cut-off part of the rock wool 22 (such as at the corner), the PE film should extend 100 mm beyond the edge of the rock wool 22.

[0025] The said hydropower installation layer 3 includes a main hydropower installation layer 31 at the bottom and a leveling layer 32 at the top. The hydropower installation layer 3 is made of cement mortar, which is the cheapest and easiest to obtain. The setting of the leveling layer 32 makes the top of the hydropower installation layer 3 at the same horizontal plane. During the subsequent construction of the floor heating installation layer 4 and the building decoration surface layer 5, as long as the floor heating installation layer 4 and the building decoration surface layer 5 maintain the same thickness, it can ensure that the finally formed ground is level. When the thicknesses of the floor heating installation layer 4 and the building decoration surface layer 5 are the same, it can ensure that the distance from the floor heating coil 41 in the floor heating installation layer 4 to the surface of the building decoration surface layer 5 is the same, so that the heating temperature at each part of the floor slab is relatively uniform.

[0026] The said floor heating installation layer 4 includes a thermal insulation layer 43 at the bottom. A reflective film is covered on the thermal insulation layer 43, so that the heat emitted by the floor heating coil 43 can be reflected to the floor slab surface layer, improving the heating effect of the floor heating system. The reflective film is laid with a floor heating coil 41, and wire meshes are laid both above and below the floor heating coil 41.

[0027] The said shock absorption and sound insulation layer 2 includes scattered soft shock absorption support blocks 21, and rock wool 22 is filled between the shock absorption support blocks 21. The shock absorption and sound insulation layer 2 is composed of rock wool 22 and shock absorption support blocks 21. A plurality of shock absorption support blocks 21 are arranged at intervals to form an integral row and are arranged on the top surface of the floor slab 1. Rock wool 22 is filled in the space between the shock absorption support blocks 21. The entire room area needs to be filled with rock wool 22, but the position where the shock absorption support blocks 21 are set needs to be avoided. Just cut out the position of the shock absorption support blocks 21 on the rock wool 22 and then lay it to form a complete shock absorption and sound insulation layer 2. The specification of the rock wool 22 is 100kg / m 3 And after its laying, it should be flush with the shock absorption support blocks 21, and its size can be selected according to the actual situation according to different room design requirements.

[0028] A floor heating coil 41 is installed in the said floor heating installation layer 4, and leveling blocks 42 are scattered on the ground between the floor heating coils 41. The top surface of the leveling blocks 42 is slightly higher than the top surface of the floor heating coils 41. The advantage of setting the leveling blocks 42 is that during the concrete pouring process of the floor heating installation layer 4, the top surface of the concrete is flush with the top surface of the leveling blocks 42. In this way, it can ensure that the finally formed floor heating installation layer 4 has a relatively consistent thickness, neither too thick nor too thin locally. When the thickness of the building decoration surface layer 5 is fixed, controlling the thickness of the floor heating installation layer 4 can make the heating temperature of the floor heating coil 41 in an ideal state.

[0029] When the thickness of the hydropower installation layer 3 is greater than 35 mm, a steel mesh with double-layer reinforcement in two directions is arranged inside it, so as to avoid situations such as hollowing, warping, and cracking during the pouring of the hydropower installation layer 3 with a large thickness. During the construction of the hydropower installation layer 3, first lay the steel mesh on the PE film. The steel mesh should be double-layer reinforced in two directions, and the middle distance is adjusted according to the size of the room. Before laying the steel mesh, it is also necessary to remove rust, which can make the steel mesh combine more closely with the hydropower installation layer 3 and increase the effect of preventing cracking and hollowing.

[0030] The shock-absorbing support blocks 21 are arranged in a dot matrix as a whole; the shock-absorbing support blocks 21 are made of a sound-absorbing material with a sponge or sponge-like structure; the thickness of the rock wool 22 and the shock-absorbing support blocks 21 is 50 mm. By using the rock wool 22 with a thickness of 50 mm in cooperation with the shock-absorbing support blocks 21, the transmission of sound can be effectively isolated.

[0031] The building decoration surface layer 5 includes the ceramic tiles 51 on the top surface and the bonding layer 52 at the bottom. The ceramic tiles 51 are bonded and fixed to the floor heating installation layer 4 through the bonding layer 52 to form the building decoration surface layer 5. The reason for choosing the ceramic tiles 51 for the building decoration surface layer 5 is that the ceramic tiles have a better heat dissipation effect for the floor heating system.

[0032] Example 2: The difference between Example 2 and Example 1 is that the solution in Example 1 is applicable to the floating structure implemented in relatively dry environments such as living rooms and bedrooms.

[0033] In this Example 2, a series of modifications are made specifically for situations where there may be long-term water storage, large amounts of water storage and drainage in a short time in toilets and kitchens. The modification solutions are as follows:

[0034] A first waterproof layer 6 is also arranged between the floor slab 1 and the shock-absorbing and sound-insulating layer 2, and a second waterproof layer 7 is also arranged between the shock-absorbing and sound-insulating layer 2 and the hydropower installation layer 3. By adopting the setting of the first waterproof layer 6, the last waterproof effect can be formed. By setting the second waterproof layer 7, the effect of waterproofing and preventing water storage on the surface layer can be achieved, so as to solve the problems of the ground in kitchens and toilets that may have water storage and moisture, and increase the anti-leakage effect to avoid the weakening or even damage of the shock-absorbing and sound-insulating layer 2 caused by leakage.

[0035] Its hierarchical relationship is in turn the floor slab 1, the first waterproof layer 6, the shock-absorbing and sound-insulating layer 2, the woodworking board 8, the second waterproof layer 7, the main hydropower installation layer 31, the leveling layer 32, the floor heating installation layer 4, the bonding layer 52, and the ceramic tiles 51.

[0036] After the construction of the floor slab 1 is completed, first conduct preliminary cleaning and leveling on the floor slab 1, and then set the first waterproof layer. After setting the first waterproof layer 6, fully cover the top surface of the first waterproof layer 6 with rock wool 22, and then embed shock-absorbing support blocks 21 on the rock wool 22. Lay a woodworking board 8 on the top surfaces of the shock-absorbing support blocks 21 and the rock wool 22, and lay a PE film on the top surface of the woodworking board 8, and then construct the second waterproof layer 7. Then pour the main layer 31 for water and electricity installation. After the water and electricity installation is completed, construct a leveling layer 32 on the main layer 31 for water and electricity installation, and then complete the construction of the entire water and electricity installation layer 3. Then install thermal insulation boards on the leveling layer 32 to form a thermal insulation layer 43, lay a reflective film on the thermal insulation layer 43, and then install a lower wire mesh and leveling blocks 42 on the reflective film. Then install the floor heating coil 41, and then install the upper wire mesh. Then backfill concrete to complete the construction of the floor heating installation layer 4. Finally, paste tiles 51 on the floor heating installation layer 4 through an adhesive layer 52 to form a building decorative surface layer 5.

[0037] To ensure the waterproof performance of the floor slab structure, the first waterproof layer 6 is a flexible waterproof layer or a rigid waterproof layer, and the four sides of the first waterproof layer 6 are turned up integrally and lapped with the bottom of the turned-up part of the second waterproof layer 7. The second waterproof layer 5 is a flexible waterproof layer, and the four sides of the second waterproof layer 7 are turned up above the building decorative surface layer 4, and the overall upward extension length is ≥500 mm.

[0038] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
