Fabricated building floor heat preservation and sound insulation integrated plate and construction method thereof

Abstract

The invention discloses a fabricated building floor heat preservation and sound insulation integrated plate and a construction method thereof. The integrated plate comprises a prefabricated plate, theprefabricated plate comprises a protective surface layer and a functional layer, the functional layer is partially or wholly elastic, has the balance leveling effect similar to the left-right balanceleveling effect of a spring and is matched with a fixing device to adjust the flatness, and the protective surface layer and the functional layer are connected with a floor through the fixing device.The functional layer is one or more of a sound insulation layer or a heat preservation layer. The heat preservation layer is one or more of a graphite polystyrene board, a polystyrene board, an extruded sheet, a phenolic aldehyde heat preservation board, a rock wool board, a foaming ceramic board, polyurethane and a cement foaming board. The construction method comprises the following steps thatcement mortars or foaming cements or self-leveling mortars are adopted for leveling the floor, the prefabricated plate is laid, and leveling and fixing are conducted through the fixing device. Leveling is convenient, the labor cost is saved, the construction efficiency is high, and the heat preservation and sound insulation use requirements of residential buildings can be met.

Description

technical field [0001] The invention relates to an integrated board and a construction method thereof, in particular to an assembled floor-floor thermal insulation and sound insulation integrated board and a construction method thereof. Background technique [0002] With the advancement of housing industrialization, prefabricated structures have attracted more and more attention due to their characteristics of industrialized production, standardized production, short construction period, and good earthquake resistance. The existing floating floor slabs also adopt prefabricated structures to meet certain sound insulation and thermal insulation requirements. Existing when actually laying, mainly contain two kinds of methods to lay. [0003] The first type of prefabricated structure includes a protective surface layer, an insulation layer, and a sound insulation layer in sequence, and the sound insulation layer at the bottom of the prefabricated structure is fixedly connected ...

AI Technical Summary

Problems solved by technology

However, the construction is relatively difficult and the construction speed is slow, which is equivalent to laying floor tiles. It has high requirements for flatness, that is, high requirements for workers, high labor costs, difficult to popularize and apply, cannot effectively reduce labor, and cannot meet the requirements of assembly

[0004] The second is that the prefabricated structure includes protective surface layer, thermal insulation layer, and sound insulation layer in turn. The bottom of the protective surface layer is fixed to the floor through positioning and leveling bolts. During the construction and use, the following problems were found: (1) The positioning and leveling bolts need to be overhead, which takes up the floor height; (2) The positioning and leveling bolts need to have high supporting force, and the protective surface must have a (3) Positioning and leveling bolts require a large concentration of force, and the sound insulation layer and insulation layer cannot be set on the upper side of the positioning and leveling bolts, otherwise it is easy to be flattened and cause deformation. The flat bolts are arranged on both sides of the sound insulation layer and the insulation layer, which is easy to generate sound bridges and cold bridges. Even if the insulation layer is added outside the positioning and leveling bolts, there is still the problem of cold bridges
