Detailed Description

The utility model is described in further detail below with reference to fig. 1-3.

At present, modern commercial buildings have light self weight, so the structure is thinner and thinner, the thickness of the general floor slab is 100-150 mm, and the sound insulation effect cannot meet the requirements of 7.1 pieces of noise and sound insulation in the residential building Specification GB 50368-2005.

Among them, the requirements for the specification of 7.1 pieces of noise and sound insulation in the "residential building Specification" GB50368-2005 are as follows:

indoor environment

7.1 noise and Sound insulation

7.1.1, the house should take noise-proof measures on the plane arrangement and the building construction; the daytime allowable noise level of the bedroom and the living room in the window closing state is 50dB, and the nighttime allowable noise level is 40dB.

The impact sound pressure level of the floor slab is not more than 75dB.

Structural measures should be taken to improve the impact sound insulation performance of the floor slab.

7.1.3, the air sound insulation, the floor should not be less than 40dB (the floor separating the residential and non-living use spaces should not be less than 55 dB), the household wall should not be less than 40dB, the outer window should not be less than 30dB, the door should not be less than 25dB;

structural measures are adopted to improve the air sound insulation performance of floors, household walls, outer windows and doors.

7.1.4, when water, heating, electricity and gas pipelines pass through the floor slab and the wall body, the periphery of the hole should adopt sealing and sound insulation measures.

Example 1

As shown in fig. 1 and 2, a floor sound insulation floating floor 1 comprises a damping sound insulation layer 2 and a pouring layer;

the three interlayers of the floor slab 1, the damping and sound-insulating layer 2 and the pouring layer form a structure similar to a sound bridge, thereby blocking sound of the top surface of the floor slab 1 and absorbing impact shock of the top surface of the floor slab 1.

The pouring layer is divided into a floating layer 3 and a building decoration surface layer 4, and the building decoration surface layer 4 is a floor.

The damping sound insulation layer 2 is composed of rock wool 22 and damping blocks 21, the plurality of damping blocks 21 are arranged on the top surface of the floor slab 1 in a whole row, the rock wool 22 is arranged at the vacant position between the damping blocks 21 and the damping blocks 21 to fill the whole room area, the rock wool 22 is required to be filled, but the position where the damping blocks 21 are arranged is required to be avoided, and the complete damping sound insulation layer 2 can be formed by only cutting the rock wool 22 out of the position where the damping blocks 21 are required to be laid again.

As preferable: the shock absorption blocks 21 are arranged in a dot shape as a whole, and the shock absorption blocks 21 are made of rubber products with high toughness;

when the floating floor is arranged in a large space, the interval between the damping blocks 21 is 600 x 600, because the size of the woodworking plate is 1200 x 2400, and when the woodworking plate is paved, the periphery needs to be provided with supporting points, the plate surface cannot be suspended, and a good sound bridge structure cannot be formed after suspending;

secondly, when the shock absorption blocks are arranged too densely, rock wool is cut too small to be crushed, and the clearance around the shock absorption blocks is increased, so that the sound insulation effect is reduced;

if the interval of snubber block is too big, too big atress inhomogeneous or support intensity inadequately can appear to unable installation again or the formation of installation back sound bridge has the problem.

The pouring layer comprises a floating layer 3 and a building decoration surface layer 4, wherein the floating layer 3 is cement mortar or other damping and sound-insulating layers, and the building decoration surface layer 4 is a floor layer.

As preferable: after the shock-absorbing blocks 21 are directly arranged on the top surface of the floor slab 1 in a matrix, rock wool 22 is fully paved between the shock-absorbing blocks 21 and the shock-absorbing blocks 21.

The floating layer 3 is cement mortar, which is the cheapest and most easily available.

Rock wool 22 gauge is 100kg/m ³ And the floor should be flush with the shock absorber block 21 after being paved, and the size of the floor is selected according to different room design requirements and actual conditions.

As preferable: because the rock wool 22 and the damping blocks 21 are soft, point pits with different degrees can appear no matter the constructor stands or the concrete is poured during construction, and the effect is not easy to see, and uneven compression is formed, so that the effect of a sound bridge is greatly reduced, or the uniformity of the sound bridge is influenced, so that the final effect of the sound bridge is influenced;

therefore, in order to solve the above problems, a sealing plate is arranged on the top surface of the damping and sound insulation layer 2, that is, a sealing plate is arranged on the top surfaces of the rock wool 22 and the damping block 21;

in order to achieve the minimum standard for solving the technical problems, the thickness of the sealing plate should not be less than 12mm, when the thickness of the sealing plate is less than 12mm, personnel tramples and the pouring layer are quite easy to damage the sealing plate after pouring is completed, so that the sealing plate, the rock wool 22 and the damping block 21 are wasted, or the sealing plate is cracked, broken and the like due to the gravity of the pouring layer, and the scheme fails.

As preferable: because the existing floating layer 3 mostly adopts cheap and easily-obtained common mortar materials as the floating layer 3, if the floating layer 3 is cement mortar, redundant liquid flows to the bottom layer under the condition of gravity infiltration, and is absorbed by the bottom layer or volatilized from various aspects;

in the scheme, the rock wool 22, the damping blocks 21 and the sealing plate are afraid of liquid, so that certain water resistance is required to be achieved on the top surface of the sealing plate, and a PE film is arranged on the top surface of the sealing plate;

the overlapping parts of the PE films are completely sealed by transparent adhesive tapes, and the overlapping parts of the PE films are not less than 100mm because the PE films are in a coiled material form and are not completely paved in the whole room, living room and the like, and the overlapping parts of the PE films are fixed and sealed by the transparent adhesive tapes.

As preferable: when the floating layer 3 is cement mortar, the conditions of hollowing, warping, cracking and the like are necessarily caused during pouring with large thickness, and when the floating layer 3 is more than 35mm, a reinforcing steel bar net sheet with bidirectional reinforcing steel bars is added in the floating layer 3;

after the PE film is paved, a cushion block is arranged at the top of the PE film, and the thickness of the cushion block is 30mm at the minimum;

as preferable: the cushion block can be a small ash block, and the ash block can be guaranteed to be fused with subsequent pouring.

At the cutting position (such as a corner position) of the rock wool 22, the plastic film should be 100mm more than the edge of the rock wool 22;

then, a reinforced net sheet is paved on the PE film, the reinforced net sheet is a bidirectional double-layer reinforcement, and different midrange is adjusted according to indoor size.

Because the floating layer 3 is cement mortar, the mortar which is poured too thick at one time is easy to crack, the hardening time of the mortar is relatively increased, and the poured concrete is poured in batches in the scheme, and generally, the concrete is poured twice.

As preferable: the damper block 21 may be a sponge, a sponge-like structure of sound absorbing material, or the like.

Example 2

The construction method of the floor sound insulation floating floor 1 comprises the following steps:

step S1: positioning and paying off:

according to the marked horizontal elevation line, the horizontal line of the ground surface layer is measured, the marked horizontal line is sprung on the surrounding wall surface, and the marked position corresponds to the elevation of the corridor, the stair platform and the steps outside the room.

Step S2: leveling cement mortar:

according to the measured horizontal line, adjusting and leveling the local elevation by using cement mortar, continuously paving from one end far away from a door of a room, firstly, scraping by using a horizontal scraping bar after paving is finished, and then rubbing and leveling the surface and calendering;

installing the damping blocks 21 according to the room and design requirements;

step S4: paving rock wool 22:

the rock wool 22 is plugged between the damping blocks 21 according to the specific size of a room and the laying requirements of the rock wool 22, so that the rock wool 22 plays a role of fixed support;

step S5: and (3) sealing plates:

the woodworking plate 31 paved above the rock wool 22 is spliced with the adjacent woodworking plate 31, and the woodworking plate 31 can play roles of supporting, compacting and protecting the rock wool 22 and the damping block 21;

step S6: paving a PE plastic film:

the overlapping between the two PE films is not less than 100mm when the PE films are paved, and the overlapping part is well stuck by using a transparent adhesive tape so as to ensure that cement paste is prevented from flowing into the rock wool 22 when concrete is poured;

at the cutting position (such as a corner position) of the rock wool 22, the PE film is 100mm more than the edge of the rock wool 22 and is fixed by a transparent adhesive tape;

step S7: punching:

measuring and paying off, highlighting the dividing lines and elevation control points, punching ribs (double-layer bidirectional reinforcing steel bar bundling and reinforcing ribs) on a woodworking plate 31 according to the elevation lines of the building finishing surface popped up around the room, and padding cushion blocks with the thickness of 30mm before punching the ribs, wherein the punching ribs are made of concrete with the same mark number and mixing ratio;

step S8: casting concrete:

1. the first concrete is compacted and scraped: firstly pouring a concrete protective layer with the thickness of about 30mm, rolling and compacting along with paving along with scraping, and then carrying out bidirectional reinforcement with the middle distance of phi 10mm of 150mm;

if a bidirectional reinforcing bar net sheet with the diameter of phi 10mm is adopted: binding the reinforcing steel meshes before pouring the concrete protective layer: the surface of the reinforced steel bar should be clean and harmless, oil stain, paint stain, rust and the like should be removed completely before use, the space is uniform during binding, the crossing point should be bound by full binding, a cushion block with the thickness of 30mm is padded below the reinforced steel bar, and the reinforced steel bar is broken at a separation joint;

the steel bar binding should be careful that the iron wire head and the wire binding head are upward, so that the PE film and the rock wool 22 are prevented from being pierced by the iron wire head and the wire binding head, and the sound insulation effect after the sound bridge is formed is prevented from being reduced.

2. And (3) compacting and strickling the second concrete: the concrete protective layer is rolled and compacted along with the spreading and scraping, and is crossly rolled back and forth for at least 3 times by adopting a 30kg roller;

rolling for the first time after strickling, rolling back and forth in the longitudinal and transverse directions, rolling to slurry, and carrying out primary calendaring by using an iron plate (the above work is required to be completed within the initial setting time t/2 of the concrete);

carrying out secondary rolling and light receiving before the initial setting of the concrete so as to enhance the bond strength between the concrete and the steel bars;

third calendaring is carried out before the concrete is finally set, so as to close cracks on the surface of the concrete

Step S9: pouring cement mortar:

after the concrete layer is finally set, pouring cement mortar, and compacting and strickling after pouring the cement mortar

Step S10: curing:

after the cement mortar floor is finally set, covering with a grass bag and sprinkling water for maintenance;

the sprinkling times should ensure that the surfaces of the covering and the concrete are wet, and the curing time is not less than 2 weeks;

water storage maintenance is not needed, and water is prevented from penetrating into the sound insulation layer from the node, so that the sound insulation effect after the sound bridge is formed is reduced.
