Description

Technical Field

[0001] The utility model relates to a sound-proof and moisture-proof mat for floor paving, and belongs to the field of construction engineering. Background Art

[0002] Traditional moisture-proof membranes have the following defects:

[0003] 1. The traditional moisture-proof membrane is a surface aluminum film and an EPP cushion layer with a thickness of 1-5mm and various specifications. The aluminum film and EPP serve as the interlayer between the floor and the ground leveling layer, isolating the impact of most of the ground moisture on the floor. However, during use, a small amount of moisture from the ground still runs under the floor through the gaps in the moisture-proof membrane. Although the EPP itself is moisture-proof, its loose structural characteristics make it more densely squeezed and close to the floor due to the ballasting of the furniture after the floor is installed. As a result, the moisture in the interlayer cannot be released, and the moisture is trapped under the floor. Over time, the bottom layer of the floor is prone to mold or deformation and arching, affecting the health of the residents or normal use. Generally, cement mortar or self-leveling is used, and then traditional moisture-proof membrane is used to lay composite flooring or laminate flooring. The most widely used method is to use cement mortar or self-leveling for leveling. Mildew and deformation are also common problems. Another method is to install the base keel, lay the subfloor, then lay the moisture-proof mat, and finally lay the floor. Although it cuts off moisture and solves the problem of air circulation through overhead partitions, the process is cumbersome and causes the bedroom floor to be raised. If floor tiles are laid in the living and dining room, the floor must be consistent with the bedroom elevation, which requires an increase in the amount of cement and sand, a significant increase in material and labor costs, and a reduction in floor height.

[0004] 2. Although traditional moisture-proof mats have the effect of cushioning and reducing sound, there is no mechanical connection or bonding between the moisture-proof mat and the floor. If the flatness of the ground leveling layer is poor or the floor is damp and arched, there will be a loud noise when people walk on the floor.

[0005] 3. At the junction of traditional floors and threshold stones, in order to prevent the floor from warping, it is generally necessary to install a pressure strip to fix it, which results in poor aesthetics. Summary of the invention

[0006] The technical problems to be solved by the utility model are: the problem of air circulation and moisture release under the floor, the problem of the floor arching upward without restraint due to moisture, and the problem of the aesthetics of the closing part.

[0007] In order to solve the above problems, the utility model provides a floor paving silent moisture-proof mat, which includes a PVC base plate, a self-adhesive tape for bonding with the ground solid layer is provided at the bottom of the PVC base plate, and a plurality of suction cups for adsorbing the wooden floor are provided on the PVC base plate. PVC itself does not contain formaldehyde, is environmentally friendly and renewable, has good aging resistance, can withstand temperatures below 100 degrees after improvement, and can be widely used as a material for interior decoration and can be recycled for secondary use.

[0008] Preferably, the PVC bottom plate is provided with U-shaped grooves distributed in a mesh shape.

[0009] More preferably, the width of the U-shaped groove is 12mm, 16mm or 20mm. When splicing, the U-shaped groove should be aligned to allow ventilation gaps under the wooden floor, so that the upper and lower parts of the floor can maintain consistent shrinkage and swelling when affected by humidity changes, the moisture content of the wooden floor can maintain a balanced state, and the thermal expansion and contraction can also be consistent when affected by temperature changes. The U-shaped groove can be used for ventilation and can also be used to embed floor heating cables.

[0010] Preferably, the PVC bottom plate is connected to the adjacent PVC bottom plate by a dovetail structure. After the dovetail structure is spliced, it can be self-locked by the floor load, and has good integrity and moisture resistance.

[0011] Preferably, a plurality of spliced ​​wooden floors are arranged on the PVC bottom plate, and adjacent wooden floors are connected via a plug-in structure.

[0012] Preferably, the lower part of the suction cup is embedded in the PVC bottom plate. The embedded silicone suction cup can be freely embedded in the position where it needs to be arranged, and has a certain leveling effect; the positions of passages and thresholds can be densely arranged, less can be placed under the bed, and it can be not placed under the fixed wardrobe to reduce costs. The suction cup has a restraining force on the upward arch of the floor, and disperses the upward deformation force to the surrounding 8-12mm expansion joints reserved on the wall to maintain the flatness of the floor. After the silicone suction cups are encrypted at the threshold, the T-shaped closing strips of the traditional floor and the threshold stone can no longer be used, and an extremely narrow closing is more beautiful. The damaged embedded silicone suction cup can be replaced according to the situation, and the floor repair and replacement is simple.

[0013] More preferably, the suction cup is made of silicone. The silicone suction cup has good flexibility, can disperse vertical, horizontal, vertical and oblique stresses, and has good shock-absorbing and noise-reducing effects. Silicone is a non-toxic, odorless and pollution-free polymer material with the advantages of high temperature resistance, acid and alkali resistance, aging resistance and wear resistance; the silicone suction cup is suitable for adsorption on smooth surfaces such as tiles and floors, and is not easy to fall off.

[0014] Preferably, the specifications of the PVC floor are 400×800mm, 500×1000mm or 600×1200mm, and the thickness is 19mm, 29mm or 39mm. The PVC floor is selected according to the width, length and construction environment of the room, and can be cut and spliced ​​to meet the requirements of different thicknesses and meet the unified elevation of the finished surface of different materials in the living room.

[0015] The utility model provides a construction method for laying moisture-proof and sound-proof pads on indoor floors, which can simultaneously solve the problems of moisture-proofing, sound-proofing, reducing arching and local leveling of solid wood floors, composite floors, laminate floors and the like.

[0018] In order to make the present invention more obvious and easy to understand, preferred embodiments are described in detail as follows in conjunction with the accompanying drawings.

[0019] Example

[0020] like Figure 1 , 2 As shown, a floor paving silent moisture-proof mat provided by the utility model comprises a PVC bottom plate 5, a self-adhesive tape 4 for bonding with a ground-fixing layer 3 (a cement leveling layer 2 is laid on the original building floor 1, and the ground-fixing layer 3 is on the cement leveling layer 2) is provided at the bottom of the PVC bottom plate 5, and a plurality of suction cups 6 for adsorbing a wooden floor 7 are provided on the PVC bottom plate 5. The PVC bottom plate 5 is provided with a mesh-distributed U-shaped groove 8. The width of the U-shaped groove 8 is 12 mm, 16 mm or 20 mm.

[0021] The PVC bottom plate 5 is connected to adjacent PVC bottom plates 5 via a dovetail structure 9 .

[0022] The PVC bottom plate 5 is provided with a plurality of spliced ​​wooden floors 7, and adjacent wooden floors 7 are connected by a plug-in structure. The lower half of the suction cup 6 is embedded in the PVC bottom plate 5. The bottom of the suction cup 6 is provided with a limiting structure extending to both sides, and the PVC bottom plate 5 is provided with a groove adapted to the limiting structure, and the bottom of both sides of the groove extends to both sides, so that the suction cup 6 can be rotated 90° after insertion to limit itself in the groove. The material of the suction cup 6 is silicone.

[0023] The specifications of the PVC bottom plate 5 are 400×800mm, 500×1000mm or 600×1200mm, and the thickness is 19mm, 29mm or 39mm.

[0024] The process construction method is as follows:

[0025] 1. Clean the original ground to make sure there are no hollows or loose joints; confirm the thickness of the floor and moisture-proof mat, and mark the elevation line.

[0026] 2. For leveling with cement mortar mixed on site, the ground base should be moist and free of water accumulation. After leveling, it should be promptly maintained within 8-12 hours to avoid shrinkage cracks. After completion, check with a 2-meter ruler to ensure the flatness is ≤3mm; the flatness of self-leveling construction is ≤2mm; for floors that do not require leveling, moisture-proof pads with thicknesses of 19mm, 29mm, 39mm, etc. can be selected.

[0027] 3. After checking that the moisture content of the leveling layer meets the standard, apply water-based environmentally friendly floor curing agent horizontally and vertically to solidify dust and prevent moisture. The curing agent needs to be applied upwards to the upper control line of the wall skirting installation.

[0028] 4. After the curing agent is dry, use a vacuum cleaner to remove the dust on the ground. Use a 40mm wide double-sided environmentally friendly self-adhesive tape, tear off one side of the protective film first, and pre-stick it to the ground around the room, about 5mm away from the wall. In the middle part of the room, stick it parallel to the door with an interval of ≤150mm. The self-adhesive tape can be strengthened in the areas where the suction cups are densely packed and the overlapping parts.

[0029] 5. Determine the starting point for laying the moisture-proof mat, which is usually the diagonal point of the door; leave a 4-6mm expansion joint against the wall, and use a utility knife or scissors to cut off the unnecessary dovetail buckle part to prevent the floor from collapsing when laid along the wall; the laying direction of the moisture-proof mat is consistent with the laying direction of the floor, and the adjacent moisture-proof mats are laid with 1 / 3-1 / 2 staggered seams. When laying, the "convex" part of the dovetail tenon should be embedded in the "concave", and the laying should be kept flat and fit. The self-adhesive tape protective film on the front should be torn off as the moisture-proof mat is laid, and any floating dust on the moisture-proof mat should be cleaned in advance.

[0030] 6. Open all packages 24 hours before laying the floor to allow the moisture content of the floor to reach equilibrium with the air in the room. At the same time, you can try laying and selecting boards. Place the ones with color defects in dark places under the cabinets and beds, and place good boards in bright places.

[0031] 7. After the oval base of the suction cup is inserted into the groove, it needs to be rotated 90° to make it clamped. The installation of the silicone suction cup is synchronized with the installation of the floor. After installing a suction cup, immediately install the floor above. Where the suction cup needs to be installed, there are force-bearing suction cups at both ends, left and right, and in the middle of each floor. During installation, dust, oil and sewage should be avoided from contaminating the contact surface of the suction cup.

[0032] 8. Floor cutting should avoid the installation area, floor installation should be staggered, the floor tongue and groove should be aligned with the floor groove and pushed in, tap with a rubber hammer to embed it. Note that composite floor and laminate floor should retain 0.5mm, solid wood floor should retain 0.8mm wet expansion joint; after the floor position is adjusted, press down to expel the air in the suction cup; there should be 8-12mm expansion joint between the floor and the wall.

[0033] 9. The installation of floor skirtings should be firm and spliced ​​at 45° at the corners. In addition to the horizontality, flatness and joint difference of the edges which should meet the acceptance standards, the junction of the skirtings and the floor should not be tightly spliced. A ventilation gap of about 1mm should be retained to eliminate abnormal noise caused by squeezing.

[0034] 10. The installed floor and threshold stone should be at the same height. The suction cups can be installed more densely here, and the extremely narrow strips should be fixed to one side of the threshold stone with structural adhesive.
