Problems solved by technology

Among them, the sound insulation pad and sound insulation coating must be used with a 40 mm thick fine stone concrete protective layer, which leads to serious occupation of the interior space by these three sound insulation layers, resulting in a significant reduction in the effective net height of the interior space, and Both will significantly increase the weight of the floor. In addition, the sound insulation layer may also appear hollowing, cracking and other phenomena during the construction process.

Abstract

The invention relates to the field of buildings, and provides sound insulation mortar, a sound insulation floor slab, a building and a construction method of the sound insulation floor slab. The soundinsulation mortar is formed by mixing functional raw materials and water, wherein the functional raw materials comprise the following components in percentage by weight: 28-42% of cement, 30-50% of elastic sound insulation particles, 0-10% of sand, 6-25% of vermiculite, 2-15% of mica powder and 5-18% of a building adhesive. The vermiculite enables the sound insulation mortar to have better workability, and is beneficial to improving the sound insulation effect of the sound insulation mortar; the mica powder is beneficial to improving the consistency of the sound insulation mortar, so that thesound insulation mortar is not prone to hollowing and cracking; and therefore, the sound insulation mortar can be laid to form a thin sound insulation layer, the self-weight of the sound insulation floor slab can be reduced, the material consumption of the sound insulation mortar can be saved, the economic efficiency of the sound insulation floor slab can be improved, protection and maintenance are not needed after the sound insulation mortar is laid, and the construction process of the sound insulation floor slab can be simplified.

Description

technical field [0001] The invention relates to the construction field, in particular to a construction method of sound-insulating mortar, sound-insulating floor, building and sound-insulating floor. Background technique [0002] The existing floor structure often has a sound insulation layer. The atlases of 08J931 "Building Sound Insulation and Sound Absorption Structure" and 15ZJ502 "Civil Building Sound Insulation and Sound Absorption Structure" disclose 30mm thick sound insulation mortar, 5mm thick sound insulation Three kinds of sound-insulating floating floor slab methods of sound-insulating coating disclose the above three kinds of sound-insulating layer structures. Among them, the sound insulation pad and sound insulation coating must be used with a 40 mm thick fine stone concrete protective layer, which leads to serious occupation of the interior space by these three sound insulation layers, resulting in a significant reduction in the effective net height of the int...
