[0003] Generally speaking, the thermal insulation and sound insulation of the original large-span building floors are achieved by taking two measures: first, when ventilation and other pipes are set under the floor, sound-absorbing panels are used to seal the ceiling and sacrifice some of the indoor space to achieve sound insulation and heat insulation effects; second, after the concrete of the floor structure is poured, 40-60mm thick fine stone concrete is constructed to level the floor as a whole to meet the needs of floor decoration.

[0040] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the present embodiment discloses a thermal insulation and sound insulation system for a large-span building floor, which comprises a plurality of thermal insulation and sound insulation panels 1, wherein the thermal insulation and sound insulation panels 1 comprise a mortar layer 12, a thermal insulation and sound insulation layer 13 and a plurality of free-to-remove edge templates 11, wherein the plurality of free-to-remove edge templates 11 are interconnected and enclose a receiving cavity, wherein the mortar layer 12 and the thermal insulation and sound insulation layer 13 are both laid in the receiving cavity, and the thermal insulation and sound insulation layer 13 is located above the mortar layer 12.

[0042] A plurality of free-edge templates 11 are connected to form a receiving cavity, and then a mortar layer 12 and a thermal insulation layer 13 are sequentially injected into the receiving cavity, thereby forming a thermal insulation board 1. In this embodiment, the mortar layer 12 is poured above the base layer and below the thermal insulation layer 13, and a bonding and leveling two-in-one mortar is used, so that the thickness of the mortar layer 12 is less than 8 mm.

[0043] The thermal insulation and sound insulation system for the floor of a large-span building may also include a plurality of flattening components 3 and a plurality of adjusting components 2 for installation on the base layer, the tops of the plurality of adjusting components 2 are all exposed on the outer surface of the thermal insulation and sound insulation board 1, the flattening components 3 are against the top of the thermal insulation and sound insulation board 1, and the flattening components 3 are connected to the adjusting components 2 and can be moved up and down on the adjusting components 2 for adjustment. By moving the flattening components 3 up and down on the adjusting components 2 for adjustment, the flattening components 3 will be tightly against the thermal insulation and sound insulation board 1, thereby adjusting the flatness of the thermal insulation and sound insulation board 1. Among them, the flattening components 3 can be pressed against one thermal insulation and sound insulation board 1 as a whole, and of course, the flattening components 3 can also be against the top surfaces of two adjacent thermal insulation and sound insulation boards 1, thereby achieving the flatness between the two adjacent thermal insulation and sound insulation boards 1, so that the top surfaces of the two adjacent thermal insulation and sound insulation boards 1 are located on the same horizontal plane.

[0044] In this embodiment, the adjustment component 2 includes a screw and a nut. The bottom of the screw will be positioned and installed on the base layer, the top of the screw will be exposed on the top surface of the thermal insulation and sound insulation board 1, and the top of the screw passes through the flattening component 3 and is connected to the nut. By rotating the nut, the flattening component 3 can be adjusted up and down, thereby achieving precise leveling and greatly improving the flatness. At the same time, the structure is simple and very convenient to use. Among them, the shape of the flattening component 3 can be strip-shaped or plate-shaped, and the specific shape is not limited. The flattening component 3 can also be a light channel steel with screw holes.

[0045] The thermal insulation layer 13 is above the mortar layer 12. The thermal insulation layer 13 can be made of a high-strength thermal insulation board with a thickness of not less than 20 mm, which ensures the thermal insulation and sound insulation functions. The material of the thermal insulation layer 13 is an organic-inorganic composite thermal insulation material, which improves the fire resistance of the thermal insulation and sound insulation system of the floor of a large-span building while ensuring the strength. Preferably, the organic-inorganic composite thermal insulation material is a silicon-graphene thermal insulation board. The lightweight and high-strength silicon-graphene thermal insulation board ensures thermal insulation and the fire resistance reaches Class A2, without the need to add other materials to enhance the strength and fire resistance.

[0046] like Figure 5 As shown, the large-span building floor insulation and sound insulation system also includes an anti-crack surface layer 4, which is laid on the top surface of several insulation and sound insulation panels 1. The anti-crack surface layer 4 is above the insulation and sound insulation layer 13, and the anti-crack surface layer 4 has a leveling and protective effect. Preferably, the anti-crack surface layer 4 includes a polymer anti-crack mortar and an alkali-resistant mesh cloth, and the polymer anti-crack mortar is composited with an alkali-resistant mesh cloth. The alkali-resistant mesh is arranged in the polymer anti-crack mortar to enhance the overall structural firmness of the anti-crack surface layer 4, thereby improving the safety and stability of the large-span building floor insulation and sound insulation system.

[0047] The top of the mortar layer 12 has at least one connection part, and the top of the thermal insulation and sound insulation layer 13 has at least one connection groove, and the connection part corresponds to the connection groove one by one, and the connection part is connected to the connection groove. The connection strength between the mortar layer 12 and the thermal insulation and sound insulation layer 13 can be effectively strengthened by connecting the connection part to the connection groove, which greatly improves the safety and stability of the thermal insulation and sound insulation system of the floor of a large-span building.

[0048] like Figure 1 As shown, this embodiment also discloses a construction method of a large-span building floor thermal insulation and sound insulation system, and the construction method of the large-span building floor thermal insulation and sound insulation system comprises the following steps:

[0049] Step S1, measuring the flatness of the base layer.

[0050] In step S1, the flatness of the base layer can be measured with the assistance of a laser theodolite. During the measurement, the highest point and the lowest point on the base layer are marked with suitable materials. The number of marks depends on the needs of the site.

[0051] Step S2, installing a plurality of adjustment components 2 according to the reference.

[0052] In step S2, since segmented casting is required, according to the pre-installation requirements of the thermal insulation and sound insulation board 1, the first layout line with a width of 1200 mm is popped out, and the screw of the positioning and adjustment component 2 is installed within the layout line with the marked height difference mark points as the reference.

[0053] Step S3, installing the thermal insulation and sound insulation board 1, and tapping the thermal insulation and sound insulation board 1 to make it roughly flat.

[0054] In step S3, a plurality of edge-free templates 11, mortar layers 12, and thermal insulation and sound insulation layers 13 are installed to form a thermal insulation and sound insulation board 1, and the thermal insulation and sound insulation board 1 is knocked to be roughly flat.

[0055] Step S4, a plurality of flattening components 3 are placed against the thermal insulation and sound insulation board 1 and connected to a plurality of adjusting components 2 respectively, and the height of the flattening components 3 is adjusted by the adjusting components 2 to achieve accurate leveling of the thermal insulation and sound insulation board 1.

[0056] In step S4, the flattening component 3 is a light channel steel with screw holes. The flattening component 3 is placed on the thermal insulation board 1 and inserted into the screw of the adjustment component 2. After the fastening nut is inserted, the nut is tightened with a wrench to achieve precise leveling. Preferably, both ends of the light channel steel have screw holes and are respectively inserted into the screws of the two adjustment components 2, and the two sides of the flattening component 3 are synchronously adjusted to make it flat.

[0057] Step S5, repeat the above steps S1-S4 to lay the next thermal insulation and sound insulation board 1, and use the previous thermal insulation and sound insulation board 1 as a reference point to level the two thermal insulation and sound insulation boards 1.

[0058] In step S5, the laid thermal insulation and sound insulation board 1 is flattened by the above steps S1-S4, and the next thermal insulation and sound insulation board 1 is laid repeatedly by repeating the above steps S1-S4 and leveling is performed with the previously laid thermal insulation and sound insulation board 1 as the reference point. After laying the thermal insulation and sound insulation board 1 and leveling the long sides, the flattening component 3 is inserted into the screw between the two thermal insulation and sound insulation boards 1, and the two ends of the flattening component 3 are pressed on the thermal insulation and sound insulation boards 1 on both sides, and the two thermal insulation and sound insulation boards 1 are placed on the same horizontal plane by rotating the nut of the adjustment component 2. It should be particularly noted that in step S1, the entire building floor can be measured, and the measurement can also be performed within the range where the corresponding thermal insulation and sound insulation board 1 needs to be installed. After the measurement of the entire building floor is completed, in step S5, only the above steps S2-S4 need to be repeated.

[0059] Through the construction method of the large-span building floor insulation and sound insulation system of this embodiment, the problems of large total thickness, sacrificed floor net height, long construction period, etc. in the existing large-span building indoor floor insulation and sound insulation system are overcome. The integrated construction of leveling and insulation of large-span building floors is realized. While achieving the technical goal of thermal insulation and heat insulation of large-span building floors, the fine stone concrete leveling structural layer is eliminated, which effectively reduces the floor load and improves the building safety factor. Moreover, the insulation and sound insulation board 1, the adjustment component 2 and the flattening component 3 effectively ensure high flatness and separation seam control requirements, achieve more precise construction, improve the surface decoration accuracy, and more convenient construction methods, saving construction period and labor.

[0060] Among them, in step S3, it is necessary to process and manufacture the thermal insulation and sound insulation board 1. Specifically, step S3 includes the following steps:

[0061] S3.1. Install the edge-free template 11 and enclose a receiving cavity.

[0062] In step S3.1, a plurality of edge-free templates 11 are bonded and positioned with an adhesive, and after they are firmly bonded, a plurality of edge-free templates 11 are connected to each other to form a receiving cavity.

[0063] S3.2. Lay a mortar layer 12 in the accommodation cavity.

[0064] In step S3.2, a mortar layer 12 is poured on top of the base layer. In order to improve the adhesion between the mortar layer 12 and the thermal insulation and sound insulation layer 13, the surface of the mortar layer 12 is scraped off with a wide sawtoothed knife to comb out serrated grooves.

[0065] S3.3, laying a thermal insulation and sound insulation layer 13 on the mortar layer 12 to form a thermal insulation and sound insulation board 1.

[0066] After step S1, step S0.5 is also included, and step S0.5 is to clean the base layer.

[0067] In step S0.5, the base layer is cleaned until there is no floating slurry, debris, or attachments that affect adhesion. If there are any sharp protrusions, they should be chiseled off and leveled. If there are any holes or cracks, they should be filled with cement mortar.

[0068] After step S5 , the method further includes step S7 , in which the flattening component 3 is removed to flatten the top surfaces of the plurality of thermal insulation and sound insulation panels 1 .

[0069] In step S7, after laying a plurality of thermal insulation and sound insulation panels 1 on the entire building floor and completing the construction and firmly bonding them, the board surfaces of the plurality of thermal insulation and sound insulation panels 1 are cleaned and the flattening components 3 are removed; at the same time, the redundant screws above the board surface can be cut off with a cutting machine, and the partial edge-free template 11 above the board surface can be removed. Preferably, in order to further improve the flatness, the uneven areas can be smoothed with a polishing machine afterwards.

[0070] After step S7 , the method further includes step S8 , which comprises: laying an anti-cracking surface layer 4 on the top surfaces of a plurality of thermal insulation and sound insulation panels 1 .

[0071] In step S8, the anti-crack surface layer 4 includes polymer anti-crack mortar and alkali-resistant mesh cloth. The polymer anti-crack mortar is constructed on the top surface of several thermal insulation and sound insulation panels 1, and the alkali-resistant mesh cloth is pressed in. After the surface is dry and has a reference strength, subsequent surface treatment is performed as needed.

[0072] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
