In order to avoid the problems caused by the conventional practice of directly removing the original exterior wall surface, as shown in fig. 1, a preferred embodiment of the present invention provides an exterior wall surface modification structure, which comprises an a interface agent layer 1, a cement mortar layer 2, a B interface agent layer 3 and an extruded sheet 4,

the A interface agent layer 1 is coated on a structural base layer 8 of an original wall body after the aged outer wall surface is removed; using A

The cement mortar layer 2 is coated on the interface agent layer A1, and the cement mortar layer 2 is leveled to a tile surface/plastering layer on the original wall body;

the B interfacial agent layer 3 is coated on the cement mortar layer 2,

and the extruded sheet 4 is bonded on the B interface agent layer, and the extruded sheet 4 is fixed on the structural base layer 1 of the original wall body after the aged outer wall surface is removed by the anchor bolt 5. Therefore, the extruded sheet 4 and the original wall body can be firmly connected into a whole, and the firmness of the whole structure is better.

The above embodiments are all based on the original wall body with the removed outer wall surface, and are not directly constructed on the original wall body, so that the aged outer wall can collapse at any time, and the construction is not easy.

The interfacial agent is formed by treating the surface of the object, which may be physically acting adsorption or coating, and often also by physicochemical action. The aim is to improve or completely modify the physico-technical properties and surface chemical properties of the material surface. The thickness of the A interface agent layer and the thickness of the B interface agent layer are both 3mm, and the adopted interface agents can be the same. Firstly, the surface of an original structure base layer 8 is treated by using an A interface agent, so that the surface performance of the original structure base layer 8 is changed, the subsequent adhesion of other coatings and other materials is easy, after a cement mortar layer 2 is coated, the surface of the original structure base layer is continuously treated by using a B interface agent, the subsequent construction is convenient, the thicknesses of the A interface agent layer and the B interface agent layer are not too thick, only a thin layer is needed, and the construction can adopt the thickness of 3 mm.

The improved structure of the outer wall surface further comprises an anti-cracking mortar layer 6, a putty layer 7 and a real stone paint layer 8 or a fluorocarbon paint layer, wherein the anti-cracking mortar layer 6 is coated on the extruded sheet 4, and the putty layer 7 is coated on the anti-cracking mortar layer 6; the real stone paint layer or the fluorocarbon paint layer is coated on the putty layer.

In order to improve the crack resistance of the crack-resistant mortar layer 6 and provide the overall strength, an alkali-resistant fiberglass mesh fabric is embedded in the crack-resistant mortar layer 6. The number of layers of the alkali-resistant glass fiber mesh cloth can be multiple.

In another preferred embodiment, the number of the embedded layers of the alkali-resistant glass fiber mesh cloth 8 is preferably 2, so that the anti-cracking effect is ensured as much as possible, the cost is not increased, and the two layers of alkali-resistant glass fiber mesh cloth 8 can be staggered, so that the anti-cracking effect is better.

In another preferred embodiment, the size of each extruded sheet is 1200mm x 600mm, 4 anchor bolts are fixed per square meter of the extruded sheet, each extruded sheet is not less than 4 anchor bolts, and the distance between any two anchor bolts is not more than 600 mm. If the extruded sheet size is little, it is also inconvenient to be under construction, and the efficiency of construction is also low moreover, and the distance between the crab-bolt is too big, can lead to firm effect not good.

The depth of the structural base layer after the anchor bolts are anchored into the original wall body and the aged outer wall surface is removed is not less than 25mm, and under the depth, the connection strength of the anchor bolts can meet the construction requirement

However, if the structural base layer of the original wall body after the aged outer wall surface is removed is an aerated concrete bricklaying layer, the anchor bolt is anchored into the structural base layer of the original wall body after the aged outer wall surface is removed, the depth of the structural base layer is not less than 50mm, and otherwise, the problems that the later stage is unstable and falls off and the like can be caused.

In a word, the structure of the utility model adopts a construction technology without removing the outer wall surface, optimizes the design and the construction scheme on the basis of achieving the same transformation effect, shortens the construction period to the maximum extent and brings good benefits to the transformation construction of the outer facade.

While embodiments of the utility model have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the utility model pertains, and further modifications may readily be made by those skilled in the art, it being understood that the utility model is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
