Environment-friendly heat preservation and shock absorption anti-crack ground system and construction method thereof

Abstract

The invention discloses an environment-friendly heat preservation and shock absorption anti-crack ground system and a construction method thereof. The ground system comprises a pressing type steel plate, a modified polyphenyl granule lightweight aggregate concrete layer, a glass fiber mesh cloth layer, a non-shrinkage type mortar transition layer and a surface layer which are paved in sequence from bottom to top. The introduction of the modified polyphenyl granule lightweight aggregate concrete layer in the ground system not only reduces the deadweight of a building, but also has excellent effects of heat preservation and shock absorption; the super-high strength non-shrinkage type transition mortar layer is introduced into the ground system, and because of the excellent flow leveling performance and super early strength performance of super-high strength non-shrinkage type transition mortar, the construction is enabled to be convenient and fast; and the early strength and high strength performance of the super-high strength non-shrinkage type transition mortar can have a protective effect on the modified polyphenyl granule lightweight aggregate concrete layer, and is beneficial tothe quick construction of the surface layer. The environmental-friendly heat preservation, shock absorption and anti-crack ground system has universality and can realize different functions by selecting different surface layers.

Description

technical field [0001] The invention belongs to the application field of environment-friendly ground materials, and in particular relates to an environment-friendly heat preservation, shock absorption, crack resistance and ground system and a construction method thereof. Background technique [0002] With the in-depth research and development of prefabricated buildings, prefabricated structural systems of light steel keel systems have gradually been widely used in various buildings due to their light weight, flexible installation, short construction period on site, low emissions, and no pollution. , such as low-rise residences, LOFT floor additions, high-rise building mezzanine additions, etc. However, in the light steel keel building system, the self-weight, shock absorption, and sound insulation of the ground floor of the floor have always been important factors affecting its design. The traditional concrete floor has its own weight (the general wet bulk density is 2400kg...

AI Technical Summary

Problems solved by technology

The traditional concrete floor has its own weight (the general wet bulk density is 2400kg / m 3 ), long construction period, easy cracking and hollowing, no heat preservation and other problems, OSB boards, cement fiber boards and other boards simply paving the ground have problems such as large vibration, no sound insulation, no heat insulation, etc.
