Construction method for foam glass heat retaining board

Abstract

The invention provides a construction method for a foam glass heat retaining board. The construction method for the foam glass heat retaining board comprises the steps of treating a concrete base, wherein residual floating dirt, a release agent, oil stains and other impurities on a concrete wall are removed, and plastering hollowing portions and other portions are cleaned; applying a concrete interfacial agent, wherein the surface of the treated concrete base is coated with the concrete interfacial agent so that the cohesive force between adhesion agent and the concrete base can be increased. The construction method for the foam glass heat retaining board has the advantages that foam glass is used as a wall heat retaining material, the thickness of a wall can be effectively reduced, the structural weight of a building is reduced, and the useable area is increased; multiple holes which penetrate through an upper face layer, a lower face layer, a reinforcing layer and a foam glass heat retaining layer are formed in the foam glass heat retaining board, when the foam glass heat retaining board is installed in the wall and cement mortar grouting is conducted, cement mortar in the holes is bonded to and connected with the wall, and the situation that after the foam glass heat retaining board is used for a long time, the portions of the wall fall, located on the two sides of the foam glass heat retaining board, and the foam glass heat retaining board falls off from the wall is avoided.

Description

Technical field [0001] The invention belongs to the technical field of foam insulation boards, and in particular relates to a construction method of foam glass insulation boards. Background technique [0002] Building energy efficiency is an extremely important policy of the country, and it is a systematic project that benefits the country and the people, and benefits future generations. Strengthening the thermal insulation of buildings plays a direct and practical role in improving people’s working and living environment conditions and saving energy. In my country’s building thermal insulation projects, high water absorption and poor durability of thermal insulation materials have always been two major problems.

Strengthening the thermal insulation of buildings plays a direct and practical role in improving people's working and living environment conditions and saving energy. In my country's building thermal insulation projects, high water absorption and poor durability of thermal insulation materials have always been two major problems. It greatly reduces the thermal insulation performance of the material, affects the effect of thermal insulation, and increases the energy consumption of the air conditioning system

Moreover, after absorbing water, the insulation layer becomes a water storage layer, which will cause the waterproof layer to bulge and damage, causing leakage, and it will still leak for a long time after the rain.

In the external wall structure, due to the need for thermal insulation, the wall needs to be thickened to meet the functional requirements. Since there is no thermal insulation material that can replace the original red brick as the wall material, external thermal insulation materials can only be used for thermal insulation. Heat insulation, so materials with light weight, good thermal insulation performance, aging resistance, non-absorbent and easy to bond are required
