specific Embodiment approach 1

[0009] Specific embodiment 1: A kind of interface agent of this embodiment is used for the construction method of compound wall body crack resistance, increases facing bonding strength, and described construction method is to brush the interface agent first pass to the wall during construction On the surface of the body or floor insulation layer, the first pass of interface agent is applied to the surface area of ​​the wall or floor insulation layer not less than 30%. Before the first pass of interface agent on the wall or floor insulation layer dries, the cement mortar Plastering or concrete can be poured onto the surface of the wall or floor insulation layer that has been coated with the interface agent for the first time.

specific Embodiment approach 2

[0010] Specific embodiment two: The difference between this embodiment and specific embodiment one is that this embodiment also adds a second pass interface agent; the construction method is to dry the first pass interface agent on the wall or floor insulation layer Finally, apply the second interface agent to the surface of the dried first interface agent, and before the second interface agent on the wall or floor insulation layer dries, plaster the cement mortar or pour concrete into the already dry surface. It can be applied on the surface of the wall or floor insulation layer coated with the interface agent for the second time. Both the first-pass interface agent and the second-pass interface agent are formed by mixing adhesive, water, water-retaining agent, and cement in proportions by weight: adhesive: water: water-retaining agent: cement=1:1.0~2.5:0.005 ~0.025:1~6. The quality of the interface agent painted on the wall or floor insulation layer should meet the testing ...

specific Embodiment approach 3

[0012] Specific embodiment three: a kind of interface agent of this embodiment is used for the construction method of compound wall body crack resistance, increases facing bonding strength, and described construction method is in the mutual seam of block insulation board of wall body or floor slab Brush the interface agent, and squeeze the block insulation boards coated with the interface agent tightly to install and bond.

Abstract

A construction method using interfacial agent to combine wall crack arresting and increase the binding strength of finishing relates to a building construction method. The purpose of the invention is to solve the problem that hollowing and cracking are normally existed in cement mortar and binding strength of tapestry brick is low. The first technical proposal comprises brushing interfacial agent on a wall body or the surface of the heat-insulating layer of a floorslab to cover, and pouring cement mortar plaster or concrete on the wall body or the surface of the heat-insulating layer of the floorslab before the interfacial agent is dried. The second technical proposal comprises brushing the interfacial agent on the seam crossing between the heat-insulating slabs of the wall body or the floorslabs, and mutually compacting, installing and binding the heat-insulating slabs which are coated with interfacial agent. The third technical proposal comprises binding the tapestry brick on the outer surface of the wall body or the floorslab before interfacial agent is dried. The fourth technical proposal comprises brushing the interfacial agent on the binding face of the tapestry brick, and sticking the tapestry brick whose interfacial agent is not dried on the outer surface of the wall body or the floorslab by using binding mortar. The invention effectively avoids and reduces the problem that the protecting layer of the cement mortar or concrete is hollowed and cracked, and increases the binding security of the tapestry brick.

Description

technical field [0001] The invention relates to a construction technique for cement mortar plastering and bonding of decorative bricks for the thermal insulation layer of a thermal insulation wall. Background technique [0002] Most of the insulation layers installed in the wall insulation and energy-saving technology are polymer insulation materials, such as molded polystyrene boards, extruded polystyrene boards, etc., and cement mortar protective layers are often applied on the outside of these polymer insulation layers. And on the outer protective layer of cement mortar plastering and then pasting decorative bricks and other decorations. Since the cement mortar cannot be bonded with the polymer insulation layer, there is a common quality problem that the cement mortar outer protective layer is cracked due to non-bonding between the plaster of the outer protective layer of the cement mortar and the insulating layer, resulting in cracking, which is seriously serious. Affec...
