The construction of the above materials is cumbersome, and the construction workers are required to have a high level of work skills. Improper operation often fails to achieve the expected thermal insulation and sound insulation effects. At the same time, the materials themselves cause great environmental pollution and personal harm, the construction process is cumbersome, the material and construction costs are high, time-consuming and labor-intensive, and the materials are more harmful, thus affecting the practicality of the construction. For this reason, we propose a new method for making thermal insulation and sound insulation concrete floors in prefabricated buildings. Summary of the invention

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Embodiment 1 See also Figure 1 and Figure 2 , the present invention provides a technical solution: a method for manufacturing a new type of thermal insulation and sound insulation concrete floor in an assembled building, the specific steps are as follows; During the main structure construction phase, the prefabricated floor 101, cast-in-place concrete floor 102 and prefabricated wall panel 106 are constructed in accordance with the construction blueprint and specification requirements. During the decoration and renovation phase, the base layer is first cleaned, the floor and the inner corners are cleaned, the loose concrete is chiseled and thoroughly swept, and the cement mortar mixture is used to smooth and polish, and the ratio of the cement mortar mixture is 1:2. If necessary, a grinder, a sandblaster and a milling machine are used to remove the floating slurry on the base layer, and a vacuum cleaner is used to remove all loose debris and dust. At the same time, loose debris and dust can also be removed by flushing with water, and then a 50-centimeter building elevation line is marked on the wall.

[0017] Specifically, a thermal insulation, sound insulation and vibration reduction cushion layer 103 is sprayed on the surface of the cast-in-place concrete floor 102. The thermal insulation, sound insulation and vibration reduction cushion layer 103 is composed of a mixture of polyurethane, special anti-cracking cellulose and latex powder. It is sprayed on site and forms a flexible thermal insulation and sound insulation layer after curing. The thickness is 4-8mm. At the same time, a special spraying machine is used on site for spraying, so that the sprayed thermal insulation, sound insulation and vibration reduction cushion layer 103 is evenly mixed on the cast-in-place concrete floor 102 instantly after being sprayed from the spray gun. The spraying process must be continuous to ensure that there is no joint and the spray During the coating operation, compressed air should be passed first, and then the material pump should be started. The thermal insulation, sound insulation, and vibration reduction cushion layer 103 at the beginning should be discarded, and the spraying can only be started after the proportion of the thermal insulation, sound insulation, and vibration reduction cushion layer 103 is normal. The distance between the spray gun head and the working surface should be appropriate, and the movement speed of the spray gun should be uniform to ensure that the thickness of the thermal insulation, sound insulation, and vibration reduction cushion layer 103 in each area is consistent. Check the spraying quality at any time during the process. If any problem is found, stop the machine immediately for inspection. Find out the cause and make adjustments before re-construction. No one is allowed to go up within 30 minutes after spraying.

[0018] Specifically, after the thermal insulation, sound insulation and vibration reduction pad layer 103 is sprayed, a vertical sound insulation sheet 107 is pasted on the top of the thermal insulation, sound insulation and vibration reduction pad layer 103 and on the surface of the assembled wall panel 106, and the vertical sound insulation sheet 107 is pasted at the corner of the wall. At the same time, the vertical sound insulation sheet 107 is higher than the protection surface of the thermal insulation and sound insulation concrete 104. After the thermal insulation, sound insulation and vibration reduction pad layer 103 is constructed, plaster cakes are applied according to the thickness requirements of the design drawings. The specifications of the plaster cakes are 50mm×50mm, and the spacing between the plaster cakes shall not be less than 1.5 meters. When the room area is large, in order to ensure the flatness of the ground, the thermal insulation and sound insulation concrete 104 can be used between the plaster cakes to make ribs with the same width of the plaster cakes, and the height is consistent with the height of the plaster cakes. At the same time, the plaster cakes are made of thermal insulation and sound insulation concrete 104 as raw materials. At the same time, the vertical sound insulation sheet 107 uses a microporous polyethylene foam sound insulation pad, which is made of a high-density foam cotton material with a thickness of 5-20mm, and an adhesive layer is attached to one side; Specifically, the thermal insulation and sound insulation concrete 104 is then poured. Before pouring, the thermal insulation and sound insulation concrete 104 is evenly mixed with a mixer, and then the mixed thermal insulation and sound insulation concrete 104 slurry is spread on the construction surface layer. The thermal insulation and sound insulation concrete 104 slurry is first roughly evenly spread, and then a two-meter-long scraper is used to smooth it according to the height of the ash cake or the marking bar to ensure sufficient vibration and a smooth surface. At the same time, the wall surface must not be contaminated during construction, and the surface layer should be completed before the initial setting. When the thermal insulation and sound insulation concrete 104 has water seepage, the dry-mixed thermal insulation and sound insulation concrete 104 is added and spread evenly, and then smoothing, roughening and calendering are carried out. During the construction process, the fallen ash should be recovered in time, the residual slurry on the wall and pipeline parts should be cleaned, the reserved holes, electrical switch boxes and other parts should be corrected and cleaned, and the finished product should be well preserved after construction. The finished product should not be grooved, drilled or polluted. It should not be hit by heavy or sharp objects. The damaged ground should be repaired in time. 24 hours after the construction is completed, watering and maintenance should be carried out for 3 consecutive days, not less than 6 times a day. In the later stage, water storage and maintenance should be carried out for not less than 7 days. Impact and vibration are strictly prohibited during the maintenance period. The thermal insulation and sound insulation concrete 104 uses cement as the main gel material, and adds lightweight porous slag, lightweight sand, reinforcing aggregate, anti-cracking fiber, admixtures, etc. in proportion to make it in the factory. The thickness is generally 40-50mm. After the maintenance period of the thermal insulation and sound insulation concrete 104 is over, the finishing layer 105 is constructed. After the finishing layer 105 is laid and before the skirting 108 is constructed, the gap between the finishing layer 105 and the vertical sound insulation sheet 107 is sealed with building sealant 109.
