Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to a floor heating ground structure and a construction method thereof. Background Art

[0002] With the development and progress of society, rooms are required to have more and more functions. In rooms with water, noise, a large number of floor pipelines and the need for heating, functions such as waterproofing, noise reduction, overhead, and heating are required. By adopting the method of superimposing various functions, the number of floor layers is too large, the thickness is relatively thick, and the process is cumbersome. And under the requirements of environmental protection, dry construction is strongly advocated in building construction. The previous large number of on-site wet operation processes can no longer meet the pace of social progress. Especially for the floors of rooms with strong noise sources such as KTVs, discos, laboratories, home theaters, etc. or the surrounding floor slabs of rooms that are particularly sensitive to noise such as hospitals, noise reduction treatment needs to be carried out. Generally, a noise reduction layer is made under the floor slab or on the ground, but the noise reduction effect for rooms with strong noise sources is not very ideal; there is also a floating floor layer using steel plates as the concrete support plate, and the steel plates need to be welded on site and the joints are spot welded. When pouring concrete, leakage will occur, and a waterproof layer and a mortar protection layer need to be added on it and then a concrete floor layer is made. The process is more, and on-site welding may damage the waterproof layer or the overhead pads, affecting the construction quality; for rooms with particularly high noise reduction requirements, the noise reduction effect of a single noise reduction layer generally cannot meet the requirements, and if the owner needs to embed pipelines such as cables and wires in the ground after taking over, the noise reduction layer needs to be removed and redone, or the thickness of the ground needs to be increased, and the practicability is not high. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-functional floor heating ground structure with multiple waterproofing, noise reduction, dry overhead and multiple functions and a construction method thereof, which optimizes the construction structure, reduces the construction process, and effectively combines and unifies waterproofing, noise reduction, overhead, heating and environmental protection, and has good economy.

[0004] In the multi-functional floor heating ground structure with multiple waterproofing, noise reduction, dry overhead and multiple functions of the present invention, it includes a waterproof layer laid on the ground. Above the waterproof layer, a noise reduction blanket and a mortar leveling layer are sequentially laid from bottom to top. Above the mortar leveling layer, a high-density fiber cement board arranged horizontally is supported by elastic members. Sound-absorbing rock wool is filled between the high-density fiber cement board and the mortar leveling layer. Above the high-density fiber cement board, a floor heating module and a floor surface layer are sequentially laid from bottom to top.

[0005] In the multi-functional floor heating ground structure with multiple waterproofing, noise reduction, dry overhead and multiple functions of the present invention, the elastic member includes an elastic pad, a square steel plate and a buffer pad which are fixedly connected in sequence from bottom to top. The elastic pad is fixedly arranged on the mortar leveling layer, and the buffer pad abuts against the high-density fiber cement board.

[0006] In the multi-functional dry overhead floor heating ground structure with multiple waterproof and noise reduction functions in the present invention, the elastic members between the high-density fiber cement board and the mortar leveling layer are divided into a first elastic member and a second elastic member. Both the first elastic member and the second elastic member are provided in multiple numbers. The multiple first elastic members are arranged at intervals along the edge of the high-density fiber cement board, and the multiple second elastic members are arranged at non-edge positions of the high-density fiber cement board. The high-density fiber cement board is connected to the square steel plate and the buffer pad of the first elastic member through fasteners.

[0007] In the multi-functional dry overhead floor heating ground structure with multiple waterproof and noise reduction functions in the present invention, multiple noise reduction blankets are provided. The joints between adjacent two noise reduction blankets are sealed with waterproof adhesive tapes. Multiple high-density fiber cement boards are provided. The joints between adjacent two high-density fiber cement boards are sealed with waterproof adhesive tapes. The floor surface layer is a composite floor.

[0008] The construction method of the above ground structure in the present invention includes the following steps:

[0009] First step, clean the ground to ensure that the ground is dry and there is no obvious water stain. Construct the waterproof layer on the ground according to the drawing requirements and conduct a full water test. After passing the test, proceed to the second step of construction.

[0010] Second step, lay the noise reduction blankets on the waterproof layer in a full-adhesive fixing manner. The joints between adjacent two noise reduction blankets are sealed with waterproof adhesive tapes. Then, lay the mortar leveling layer on the noise reduction blankets and strictly control the levelness. Conduct secondary troweling before the final setting of the cement and recheck the levelness again.

[0011] Third step, manufacture the elastic members, fix the manufactured elastic members on the mortar leveling layer. Then, lay the sound-absorbing rock wool on the mortar leveling layer. The laying height of the sound-absorbing rock wool is not lower than the height of the elastic members. After that, lay the high-density fiber cement boards on the elastic members. The joints between adjacent two high-density fiber cement boards are sealed with waterproof adhesive tapes.

[0012] Fourth step, lay the floor heating module above the high-density fiber cement board in a dry construction method. Then, lay the floor surface layer above the floor heating module.

[0013] In the construction method of the present invention, the specific steps of manufacturing the elastic members in the third step are as follows:

[0014] Fabricate a right-angled L-shaped positioning plate with a width of 50 mm, where the two outer side lengths of the positioning plate are both 150 mm and the two inner side lengths are both 100 mm. Vertically weld a right-angled L-shaped baffle on one side of the positioning plate. Set the height of the baffle perpendicular to the positioning plate to 80 mm. Let the outer side and the inner side of the positioning plate be located on the outer side and the inner side of the baffle respectively, and let the two inner side surfaces of the baffle be parallel to the two outer side edges of the positioning plate respectively. Set the distance between the two inner side surfaces of the baffle and the outer side edges of the positioning plate parallel to them to 20 mm.

[0015] Fabricate a cube-shaped elastic cushion block with a side length of 50 mm, a square steel plate with a side length of 150 mm and a thickness of 6 mm, and a square buffer pad with a side length of 150 mm and a thickness of 10 mm. Clean one side surface of the steel plate and the buffer pad and apply structural adhesive. Then bond the steel plate and the buffer pad firmly with all four sides aligned. Place the positioning plate on the side surface of the steel plate where the buffer pad is not bonded, and let the side surface of the positioning plate without the welded baffle abut against the side surface of the steel plate where the buffer pad is not bonded. Align the two outer side edges of the positioning plate with two adjacent sides of the steel plate respectively. Apply structural adhesive on one side surface of the elastic cushion block. Let the side surface of the elastic cushion block with the applied structural adhesive face and be parallel to the steel plate, and let the two side surfaces of the elastic cushion block perpendicular to the steel plate abut against the two inner side edges of the positioning plate respectively. Then move the elastic cushion block along the positioning plate towards the steel plate until the elastic cushion block contacts the steel plate. Then press the elastic cushion block to bond it firmly with the steel plate. Remove the positioning plate and repeat the above operation to fabricate multiple elastic parts.

[0016] The construction method in the present invention, wherein the specific steps of fixing the fabricated elastic parts on the mortar leveling layer in the third step are as follows:

[0017] Draw vertical and horizontal cross positioning lines on the mortar leveling layer. Set the distance between two adjacent vertical positioning lines to 600 mm, and the distance between two adjacent horizontal positioning lines to 600 mm as well. Let the side surface of the positioning plate without the welded baffle abut against the mortar leveling layer. Move the positioning plate to the intersection of a vertical positioning line and a horizontal positioning line, and let the two outer side edges of the positioning plate coincide with the vertical positioning line and the horizontal positioning line at this intersection respectively.

[0018] Apply structural adhesive on the side surface of the elastic cushion block opposite to the steel plate. Then let the side surface of the elastic cushion block with the applied structural adhesive face downwards towards the mortar leveling layer, and let two adjacent sides of the steel plate abut against the two inner side surfaces of the baffle respectively. Then move the elastic part downwards along the baffle until the elastic cushion block contacts the mortar leveling layer. Then press the elastic part to bond it firmly with the mortar leveling layer. Remove the positioning plate and repeat the above operation until an elastic part is set at the intersection of each vertical positioning line and horizontal positioning line.

[0019] The construction method in the present invention, wherein the specific steps of laying the high-density fiber cement board on the elastic member in the third step are as follows:

[0020] The high-density fiber cement board is a rectangular board or a square board. The side length of the high-density fiber cement board is set as a multiple of the distance between two adjacent elastic pads longitudinally or transversely. The high-density fiber cement board is laid on the buffer pad of the elastic member. The two adjacent sides of the high-density fiber cement board are respectively denoted as the first side and the second side. Align the first side with the longitudinal center line of the buffer pads of a group of longitudinally arranged elastic members, and align the second side with the transverse center line of the buffer pads of a group of transversely arranged elastic members. Then, fix the high-density fiber cement board and the elastic members abutting against its edges through fasteners. Repeat the above operations to lay the next high-density fiber cement board, and make the next high-density fiber cement board close to the already laid high-density fiber cement board until all are laid.

[0021] The construction method in the present invention, wherein the specific steps of fixing the high-density fiber cement board and the elastic members abutting against its edges through fasteners are as follows: The fasteners are self-tapping screws, and let the self-tapping screws pass through the high-density fiber cement board, the buffer pad and the steel plate from top to bottom in sequence.

[0022] The construction method in the present invention, wherein the floor surface layer in the fourth step adopts a composite floor.

[0023] The difference between the present invention and the prior art lies in that the present invention optimizes the positions of the noise reduction blanket and the waterproof layer, combines the noise reduction blanket protection layer, the waterproof layer protection layer and the mortar leveling layer into one mortar layer to protect the waterproof layer; uses elastic members as supports to generate an overhead layer, and fills sound-absorbing rock wool in the overhead layer; uses high-density fiber cement boards to replace the reinforced concrete cast-in-place layer and the steel plate support layer, combining the two into one, and the surface of the high-density fiber cement board is flat, and the floor decoration surface layer can be directly constructed on it; uses waterproof tape to seal the joints of the high-density fiber cement boards tightly as a waterproof layer to replace the waterproof layer and the mortar protection layer set by the wet operation of the surface layer, greatly streamlining the number of structural layers, reducing processes, being economical and reasonable, and having a fast construction speed. Thus, the present invention optimizes the construction structure, reduces construction processes, effectively combines and unifies waterproofing, noise reduction, overhead, heating and environmental protection, and has good economy.

Specific embodiments

[0034] It should be noted that the ground in the present invention refers to both the ground floor and the floor slab 1 ground of the second floor and above floors, and of course also refers to the ground of the basement.

[0035] As Figure 1 shown and in combination with Figure 5 、 6 shown, the multi - layer waterproof, noise - reducing, dry - type overhead and multi - functional floor heating ground structure in the present invention includes a waterproof layer 2 laid on the ground. In this embodiment, the waterproof layer 2 is laid on the floor slab 1 ground. Above the waterproof layer 2, a noise reduction blanket 3 and a mortar leveling layer 4 are laid in sequence from bottom to top. Above the mortar leveling layer 4, a horizontally arranged high - density fiber cement board 6 is supported by an elastic member 17. Sound - absorbing rock wool 5 is filled between the high - density fiber cement board 6 and the mortar leveling layer 4. Above the high - density fiber cement board 6, a floor heating module 7 and a floor surface layer 8 are laid in sequence from bottom to top.

[0036] In the multi - layer waterproof, noise - reducing, dry - type overhead and multi - functional floor heating ground structure in the present invention, the elastic member 17 includes an elastic cushion block 9, a square steel plate 10 and a buffer pad 11 fixedly connected in sequence from bottom to top. The elastic cushion block 9 is fixedly arranged on the mortar leveling layer 4, and the buffer pad 11 abuts against the high - density fiber cement board 6.

[0037] In the multi-functional dry-air floor heating ground structure with multiple waterproof and noise reduction functions in the present invention, the elastic members 17 between the high-density fiber cement board 6 and the mortar leveling layer 4 are divided into a first elastic member and a second elastic member. Both the first elastic member and the second elastic member are provided in multiple numbers. The multiple first elastic members are arranged at intervals along the edge of the high-density fiber cement board 6, and the multiple second elastic members are arranged at non-edge positions of the high-density fiber cement board 6. The high-density fiber cement board 6 is connected to the square steel plate 10 and the buffer pad 11 of the first elastic member through fasteners.

[0038] In the multi-functional dry-air floor heating ground structure with multiple waterproof and noise reduction functions in the present invention, multiple noise reduction blankets 3 are provided. The joints between adjacent two noise reduction blankets 3 are sealed with waterproof adhesive tape. Multiple high-density fiber cement boards 6 are provided. The joints between adjacent two high-density fiber cement boards 6 are sealed with waterproof adhesive tape. The floor surface layer 8 is a composite floor. The material of the floor heating module 7 is extruded board.

[0039] The noise reduction blanket 3, the high-density fiber cement board 6, the sound-absorbing rock wool 5, and the floor heating module 7 are all prior arts, and their specific structures will not be described in detail herein. The buffer pad 11 is square, and its size is the same as that of the square steel plate 10, and the two are bonded and fixed by aligning the four sides. The elastic cushion block 9 is bonded in the middle of the steel plate 10, and the elastic cushion block 9 and the buffer pad 11 are respectively located on the opposite sides of the steel plate 10.

[0040] The fasteners adopt self-tapping screws 12. The self-tapping screws 12 pass through the buffer pad 11 and the steel plate 10 of the first elastic member from top to bottom through the high-density fiber cement board 6, and then fix the cement board 6 on the first elastic member.

[0041] As Figure 7 shown, and in combination with Figures 1-6 shown, the construction method of the above ground structure in the present invention includes the following steps:

[0042] The first step: Clean the ground to ensure that the ground is dry and there is no obvious water stain. Construct the waterproof layer 2 on the ground according to the drawing requirements and conduct a full water test. After passing the test, proceed to the second step of construction.

[0043] The second step: Lay the noise reduction blanket 3 on the waterproof layer 2 in a full-bonding and fixing manner. The joints between adjacent two noise reduction blankets 3 are sealed with waterproof adhesive tape. Then, lay the mortar leveling layer 4 on the noise reduction blanket 3 and strictly control the levelness. Conduct secondary finishing before the final setting of the cement and recheck the levelness again.

[0044] Step 3: Manufacture the elastic member 17, fix the manufactured elastic member 17 on the mortar leveling layer 4, then lay the sound-absorbing rock wool 5 on the mortar leveling layer 4, the laying height of the sound-absorbing rock wool 5 is not lower than the height of the elastic member 17, and then lay the high-density fiber cement board 6 on the elastic member 17. The joints between two adjacent high-density fiber cement boards 6 are sealed with waterproof tape.

[0045] Step 4: Adopt a dry construction method to lay the floor heating module 7 above the high-density fiber cement board 6, and then lay the floor surface layer 8 above the floor heating module 7.

[0046] In the above Step 3, the laying height of the sound-absorbing rock wool 5 is not lower than the height of the elastic member 17, that is, equal to or slightly higher than the height of the elastic member 17. In this way, when the cement board 6 is laid on the elastic member 17, the cement board 6 can compact the sound-absorbing rock wool 5, that is, ensure that the sound-absorbing rock wool 5 can be filled between the cement board 6 and the mortar leveling layer 4.

[0047] In the construction method of the present invention, the specific steps of manufacturing the elastic member 17 in the above Step 3 are as follows:

[0048] As Figure 2 shown, manufacture a right-angled L-shaped positioning plate 13 with a width d of 50 mm. The thickness of the positioning plate 13 can be 3 mm - 5 mm. Let the two outer side lengths L of the positioning plate 13 be both 150 mm, and the two inner side lengths L' be both 100 mm. The inner side of the positioning plate 13 refers to the side of the 90° angle, and the outer side is the side relative to the 90° angle side. Vertically weld a right-angled L-shaped baffle 14 on one side of the positioning plate 13. The height of the baffle 14 perpendicular to the positioning plate 13 is set to 80 mm. Let the outer side and the inner side of the positioning plate 13 be located outside and inside the baffle 14 respectively, that is, both outer side lengths of the positioning plate 13 are located outside the baffle 14, and both inner side lengths of the positioning plate 13 are located inside the baffle 14, and let the two inner side surfaces of the baffle 14 be parallel to the two outer side lengths of the positioning plate 13 respectively. Set the distance a between the two inner side surfaces of the baffle 14 and the outer side lengths of the positioning plate 13 parallel to them to be 20 mm. Similar to the positioning plate 13, the inner side of the baffle 14 refers to the side of the 90° angle, and the outer side refers to the side relative to the 90° angle side.

[0049] As Figure 3As shown in the figure, an elastic cushion block 9 in the shape of a cube with a side length of 50 mm is fabricated, a square steel plate 10 with a side length of 150 mm and a thickness of 6 mm and a square buffer pad 11 with a side length of 150 mm and a thickness of 10 mm are fabricated. One side surface of the steel plate 10 and the buffer pad 11 is cleaned and brushed with structural adhesive. Then, the steel plate 10 and the buffer pad 11 are firmly bonded in a way that all four sides are aligned. The positioning plate 13 is placed on the side surface of the steel plate 10 where the buffer pad 11 is not bonded, and the side surface of the positioning plate 13 where the baffle 14 is not welded abuts against the side surface of the steel plate 10 where the buffer pad 11 is not bonded. The two outer sides of the positioning plate 13 are respectively aligned with two adjacent sides of the steel plate 10. Structural adhesive is brushed on one side surface of the elastic cushion block 9. The side surface of the elastic cushion block 9 brushed with structural adhesive faces and is parallel to the steel plate 10, and the two side surfaces of the elastic cushion block 9 perpendicular to the steel plate 10 respectively abut against the two inner sides of the positioning plate 13. Then, the elastic cushion block 9 is moved along the positioning plate 13 towards the direction close to the steel plate 10 until the elastic cushion block 9 contacts the steel plate 10. Then, the elastic cushion block 9 is pressed to firmly bond it with the steel plate 10. The positioning plate 13 is removed, and the above operations are repeated to fabricate a plurality of elastic members 17. The elastic cushion block 9 is bonded on the side surface of the steel plate 10 where the buffer pad 11 is not bonded, that is, the elastic cushion block 9 and the buffer pad 11 are respectively bonded on the opposite side surfaces of the steel plate 10.

[0050] As Figure 3 shown in the figure, after the two outer sides of the positioning plate 13 are respectively aligned with two adjacent sides of the steel plate 10 (the outer side length of the positioning plate 13 is equal to the side length of the steel plate 10, so the two can be aligned), the two side surfaces of the elastic cushion block 9 perpendicular to the steel plate 10 respectively abut against the two inner sides of the positioning plate 13. At this time, as shown in Figure 3 the figure, the four side surfaces of the elastic cushion block 9 perpendicular to the steel plate 10 are respectively denoted as the upper side surface, the lower side surface, the left side surface and the right side surface, the four sides of the steel plate 10 are respectively denoted as the upper side, the lower side, the left side and the right side. The distance from the upper side surface of the elastic cushion block 9 to the upper side of the steel plate 10 is the width of the positioning plate 13, which is 50 mm. The distance from the lower side surface of the elastic cushion block 9 to the lower side of the steel plate 10 is the inner side length L' of the positioning plate 13 minus the side length of the elastic cushion block 9, that is, 100 - 50 = 50 mm. The distance from the left side surface of the elastic cushion block 9 to the left side of the steel plate 10 is the width of the positioning plate 13, which is 50 mm. The distance from the right side surface of the elastic cushion block 9 to the right side of the steel plate 10 is the inner side length L' of the positioning plate 13 minus the side length of the elastic cushion block 9, that is, 100 - 50 = 50 mm. Thus, it can be seen that at this time, the elastic cushion block 9 is located in the exact middle of the steel plate 10. Of course, after the elastic cushion block 9 is bonded to the steel plate 10 in this way, the elastic cushion block 9 is bonded in the exact middle of the steel plate 10.

[0051] For the construction method in the present invention, the specific steps of fixing the fabricated elastic member 17 on the mortar leveling layer 4 in the third step are as follows:

[0052] As shown in Figure 4 , 5 shown, on the mortar leveling layer 4, draw vertical and horizontal positioning lines. The distance between two adjacent longitudinal positioning lines 15 is set to 600 mm, and the distance between two adjacent transverse positioning lines 16 is also set to 600 mm. Make the side of the un-welded baffle 14 of the positioning plate 13 abut against the mortar leveling layer 4. Move the positioning plate 13 to the intersection of a longitudinal positioning line 15 and a transverse positioning line 16, and make the two outer sides of the positioning plate 13 coincide with the longitudinal positioning line 15 and the transverse positioning line 16 at this intersection respectively.

[0053] Brush structural adhesive on the side of the elastic cushion block 9 facing the steel plate 10. Then, make the side of the elastic cushion block 9 brushed with structural adhesive face downward towards the mortar leveling layer 4, and make two adjacent sides of the steel plate 10 abut against the two inner sides of the baffle 14 respectively. Then, move the elastic member 17 downward along the baffle 14 until the elastic cushion block 9 contacts the mortar leveling layer 4. Then, press the elastic member 17 to make it firmly bonded to the mortar leveling layer 4 (at this time, the side of the elastic cushion block 9 brushed with structural adhesive is bonded to the mortar leveling layer 4). Remove the positioning plate 13, and repeat the above operations until an elastic member 17 is set at the intersection of each longitudinal positioning line 15 and transverse positioning line 16. After the elastic member 17 is bonded to the mortar leveling layer 4, since the side of the elastic cushion block 9 facing the steel plate 10 is bonded to the mortar leveling layer 4, the elastic member 17 from bottom to top is the elastic cushion block 9, the steel plate 10 and the buffer pad 11 in sequence, and both the steel plate 10 and the buffer pad 11 are arranged horizontally.

[0054] As shown in Figure 4 shown, the distance c from the center of the elastic cushion block 9 to the longitudinal positioning line 15 is c = a + b, where a is the distance between the longitudinal inner side of the baffle 14 and the longitudinal outer side of the positioning plate 13, and b is the distance from the center of the elastic cushion block 9 to the longitudinal side of the steel plate 10. Since the elastic cushion block 9 is located exactly in the middle of the steel plate 10, b is half of the side length of the steel plate 10. In this way, c = 20 + 75 = 95 mm. Similarly, the distance from the center of the elastic cushion block 9 to the transverse positioning line 16 is also 95 mm.

[0055] When installing the elastic member 17, proceed from one end to the other end, such as from left to right or from top to bottom of Figure 5 , to avoid touching the already installed elastic members 17. During construction, in combination with the on-site situation, leave a passage for transporting the high-density fiber cement board 6 before construction. Transport the high-density fiber cement board 6 to the corresponding position for storage and standby. The wheelbase of the transport vehicle is a multiple of 600 to reduce the collision with the already installed elastic members 17.

[0056] For the construction method in the present invention, the specific steps of laying the high-density fiber cement board 6 on the elastic member 17 in the third step are as follows:

[0057] As shown inFigure 6 As shown, the high-density fiber cement board 6 is in the shape of a rectangular board or a square board. The side length of the high-density fiber cement board 6 is set as a multiple of the distance between two adjacent elastic cushion blocks 9 in the longitudinal or transverse direction. The high-density fiber cement board 6 is laid on the buffer pad 11 of the elastic member 17. The two adjacent sides of the high-density fiber cement board 6 are respectively denoted as the first side and the second side. Align the first side with the longitudinal center line of the buffer pads 11 of a group of longitudinally arranged elastic members 17, and align the second side with the transverse center line of the buffer pads 11 of a group of transversely arranged elastic members 17. Then, fix the high-density fiber cement board 6 and the elastic member 17 abutted against its edge through fasteners. Repeat the above operations to lay the next high-density fiber cement board 6, and make the next high-density fiber cement board 6 closely adjacent to the already laid high-density fiber cement board 6 until all are laid.

[0058] The thickness of the high-density fiber cement board 6 is generally 25 mm, which can be determined according to the ground load. Each board can be a rectangular board of 1200×2400 mm, and of course, it can also be Figure 6 the rectangular board of 1200×1800 mm as shown, or the side length is a multiple of 600 mm. Since the distance between two adjacent longitudinal or transverse positioning lines 16 is 600 mm, and the distances from the center of the elastic cushion block 9 to the adjacent longitudinal positioning line 15 and transverse positioning line 16 are both 95 mm, the distance between two adjacent elastic cushion blocks 9 in the longitudinal or transverse direction is 600 mm.

[0059] Since the buffer pad 11 is aligned with the four sides of the steel plate 10, and the elastic cushion block 9 is located exactly in the middle of the steel plate 10, for two groups of adjacent elastic members 17 arranged longitudinally, the distance between the longitudinal center lines of the buffer pads 11 of the two groups of elastic members 17 is equal to the distance of 600 mm between the elastic cushion blocks 9 of two adjacent elastic members 17 in the transverse direction; for two groups of adjacent elastic members 17 arranged transversely, the distance between the transverse center lines of the buffer pads 11 of the two groups of elastic members 17 is equal to the distance of 600 mm between the elastic cushion blocks 9 of two adjacent elastic members 17 in the longitudinal direction. In this way, when laying the high-density fiber cement board 6 on the elastic member 17, based on the side length of the cement board 6 being a multiple of 600, when the first side is aligned with the longitudinal center line of the buffer pads 11 of a group of longitudinally arranged elastic members 17, the side of the cement board 6 opposite to the first side is also aligned with the longitudinal center line of the buffer pads 11 of the other group of longitudinally arranged elastic members 17. Similarly, when the second side of the cement board 6 is aligned with the transverse center line of the buffer pads 11 of a group of transversely arranged elastic members 17, the side of the cement board 6 opposite to the second side is also aligned with the transverse center line of the buffer pads 11 of a group of transversely arranged elastic members 17. Then, fix the cement board 6 and the elastic member 17 abutted against its edge through fasteners, and the elastic member 17 abutted against its non-edge position such as the middle does not need to be fixed.

[0060] The construction method in the present invention, wherein the specific steps of fixing the high-density fiber cement board 6 and the elastic member 17 abutted against its edge by fasteners are as follows: The fasteners adopt self-tapping screws 12, and let the self-tapping screws 12 pass through the high-density fiber cement board 6, the buffer pad 11 and the steel plate 10 from top to bottom in sequence. In this way, the cement board 6 and the elastic member 17 are fixed together.

[0061] The construction method in the present invention, wherein the floor surface layer 8 in the fourth step adopts a composite floor. The material of the floor heating module 7 in the fourth step is extruded board.

[0062] The difference between the present invention and the prior art lies in that the present invention optimizes the positions of the noise reduction blanket 3 and the waterproof layer 2, combines the protective layer of the noise reduction blanket 3, the protective layer of the waterproof layer 2 and the mortar leveling layer 4 into one mortar layer to protect the waterproof layer; uses the elastic member 17 as a support to generate an overhead layer, and fills the overhead layer with sound-absorbing rock wool 5; uses the high-density fiber cement board 6 to replace the reinforced concrete cast-in-place layer and the steel plate support layer, combining the two into one, and the surface of the high-density fiber cement board 6 is flat, and the floor decoration surface layer can be directly constructed on it; uses waterproof tape to seal the joints of the high-density fiber cement board 6 as a waterproof layer to replace the waterproof layer and the mortar protective layer set by the wet operation of the surface layer, greatly streamlining the number of structural layers, reducing the construction process, being economical and reasonable, and having a fast construction speed. It can be seen that the present invention optimizes the construction structure, reduces the construction process, effectively combines and unifies waterproofing, noise reduction, overhead, heating and environmental protection, and has good economy.

[0063] The present invention adopts four layers of buffer and noise reduction layers including the noise reduction blanket 3 noise reduction layer, the elastic cushion block 9 plus the sound-absorbing rock wool 5 noise reduction layer, the buffer pad 11 and the floor heating module 7 made of extruded board, and has good noise reduction effect, and is particularly suitable for rooms with particularly high noise reduction requirements.

[0064] The support layer in the present invention is changed from a steel plate to a high-density fiber cement board 6, without on-site welding, which can prevent the possible damage to the waterproof layer 2 or the overhead elastic cushion block 9 during welding, thus ensuring the construction quality and avoiding the occurrence of fire.

[0065] The present invention uses the elastic cushion block 9 as a support pad, which can generate an overhead layer and reduce noise, serving two purposes. As for the material of the elastic cushion block 9, any elastic material that meets the requirements of building construction can be used.

[0066] Below the mortar leveling layer 4 of the present invention is completed by the construction unit, and above it can be handed over to the owner for construction. The owner can plan and pre-embed pipelines such as cables and wires on the ground according to actual needs and centrally place them in the overhead layer, preventing the situation of demolishing and redoing the ground for pipelines or increasing the ground thickness. Moreover, the construction above the mortar leveling layer 4 is all dry module construction, with good environmental protection effect, simple operation, strong adaptability, high practicability, and convenient for later maintenance.

[0067] In the present invention, the joints of the noise reduction blanket 3 are sealed with waterproof tape, which not only protects the waterproof layer but also is equivalent to adding an additional waterproof layer. The high-density fiber cement board 6 has certain waterproof properties. When wet work is used for floor decoration, the joints of the high-density fiber cement board 6 can be sealed tightly with waterproof tape, which can also serve as a waterproof layer. It has multiple functions in one layer and has a good waterproof effect.

[0068] In the present invention, the elastic cushion blocks 9 and the steel plates 10 are pasted, and the elastic members 17 are installed using special positioning tools. The positioning tools are the above-mentioned positioning plates 13 and baffle plates 14, with accurate positioning and fast construction speed.

[0069] The surface of the high-density fiber cement board 6 is flat, with high strength, fast installation speed, eliminating the reinforced concrete cast-in-place layer and the steel plate support layer, and is easy to operate.

[0070] The present invention has fewer layers, multiple functions per layer, triple waterproofing, four-layer buffer for noise reduction, effectively combining and unifying waterproofing, noise reduction, suspension, heating, and environmental protection. It is assembled in modules and constructed by dry methods, with good noise reduction effect, fast construction speed, economic rationality, and easy operation.

[0071] In the first step of the construction method of the present invention, after cleaning the ground, if there are pits on the ground, the pits are leveled and polished with repair materials. The above-mentioned repair materials can be cement mortar mixed with 108 glue. The construction of the waterproof layer 2 is prior art and will not be elaborated here.

[0072] In the second step of the present invention, the noise reduction blanket 3 is laid on the waterproof layer 2 in a full-adhesion fixed manner, which can prevent local warping of the noise reduction blanket 3. When workers lay the noise reduction blanket 3, they should wear cotton cloth shoe covers to prevent damage to the waterproof layer 2. The thickness of the mortar leveling layer 4 laid on the noise reduction blanket 3 is 30 mm.
