A construction method of foam concrete roof thermal insulation and waterproof integrated system

Abstract

The invention provides a construction method of an insulating and waterproof integrated system for a foam concrete roof. The method comprises the following steps: 1, pouring foam concrete according to gradient, average thickness and energy-saving technical indexes required by design to finish construction of a slope finding and insulating layer of the cast-in-situ foam concrete; 2, dividing the slope finding and insulating layer of the cast-in-situ foam concrete into a plurality of paved regions, pre-paving one of the paved regions, pouring polymer cement glue onto the paved region, coiling a bearing waterproof roll on a sleeve, and pushing the sleeve to enable the bearing waterproof roll to be tightly attached to the polymer cement glue, the overlap joint of the bearing waterproof roll between two adjacent paved regions to be tightly adhered through the polymer cement glue, and construction of a polymer cement glue bonding layer and the bearing waterproof roll layer to be finished; and 3, pouring anti-crack mortar on the bearing waterproof roll layer to finish construction of an anti-crack mortar protecting layer. The construction method provided by the invention is short in construction work period, small in roof load and good in waterproof and insulating effect.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a foam concrete roof thermal insulation and waterproof integrated system. Background technique [0002] In the field of construction, with the continuous improvement of people's requirements for building quality, the current roof structure is required to have dual functions of heat preservation and waterproofing. [0003] The current traditional roof structure includes cement mortar leveling layer, insulation layer, cement bonding layer, waterproof membrane layer and mortar surface layer (or crushed stone concrete surface layer) arranged in sequence from bottom to top. The construction method is: on the roof Lay a layer of cement mortar leveling layer, lay a layer of insulation layer on the cement mortar leveling layer, then pour a layer of cement bonding layer on the insulation layer, use a scraper to spread the cement bonding layer, and th...

AI Technical Summary

Problems solved by technology

[0004] The traditional construction method has the following disadvantages: many construction procedures, long construction period, high cost, and the air under the waterproof membrane cannot be completely exhausted, resulting in the detachment of the waterproof membrane from the base material, that is, hollowing; and in During the construction process, quality problems such as poor surface flatness of the waterproof membrane are caused by missing scrapes and uneven force
