Heat preservation board of wall

Abstract

This invention discloses a wall heat preservation felt, which arranges a groove on the bubble felt which has a certain thickness, and it is close to the one side of the wall, wherein the groove is the dovetail groove or the conical hole. When the felt applies to the wall, the slurry which is applies on the wall is put into the dovetail groove or the conical hole of the felt, and the slurry can support the felt firmly after hydrating, which likes the 'expansion bar' or the 'expansion annul' which is embedded in the felt. The conventional felt face is smooth, which applies to the wall depends on the slurry and uses the expansion snail fixation technology The structure of the felt in this invention is logical, the joint with the wall still uses the conventional join wall brick technology, the construction process is simple, the manual work cost and material cost all decrease, which is convenient for extending and using and solves the joint problem between the bubble felt and the wall.

Description

technical field [0001] The invention relates to a wall heat insulation material for buildings, more specifically to a wall heat insulation board. Background technique [0002] With the acceleration of urban modernization and the continuous improvement of people's living standards, people's living standards are also constantly improving. While the living standard is improving, how to further improve the comfort of living, and at the same time reduce the energy consumption of buildings, improve the utilization rate of energy, and accelerate the speed of building energy conservation have attracted the attention of the government and all walks of life, making my country's The work of building energy conservation continues to be promoted, especially in today's era when air conditioners are widely used and electricity is in short supply. At present, no matter for the buildings that have been completed or the buildings that have not yet been completed, they all only rely on the str...

Problems solved by technology

But there are still the following disadvantages: because the heat insulation board usually adopts polymer foam heat insulation board, the foam heat insulation board and the wall are two kinds of materials with different properties, the adhesion between the foam heat insulation board and cement mortar is poor, and the foam heat insulation When the board is attached to the outside of the wall 14, it is easy to fall off. As time goes by, the heat insulation board 10 attached to the wall 14 sometimes falls off in large pieces.

Therefore, the construction process is cumbersome and complicated, resulting in an increase in labor costs and material costs, which restricts the promotion and use of this technology. So far, the problem of bonding between the foam insulation board and the wall has not been fundamentally solved.
