Firstly, checking a base layer, 1, knowing a wall body using material of a construction base surface; 2. Knowing the design strength grade of plastering mortar and the condition of whether steel wire meshes are hung on plastering or not; 3. Checking the flatness of the base surface, namely, checking whether the internal and external corners are straight, and whether the wall surface has hollowing and cracking phenomena, and recording (the flatness of the base surface is checked and required to be not more than 3mm, the hollowing area is not more than 30c of the square meter, if cracking occurs, the crack causes need to be analyzed and then processed, the internal and external corners are straight, and the horizontal verticality is controlled within 2 mm); 4. Checking whether the yielding space of the two sides of the door and window meets the pasting distance of the heat-insulating plate, whether the side distances of the external corners of the four side window edges are equal, and whether the door and window frame is vertical.

Dividing and snapping lines strictly according to a dividing drawing; the horizontal line needs to be determined by a horizontal pipe, the vertical line needs to be corrected by a plumb bob, the dividing joints of all the plates need to be uniformly agreed, and the horizontal line and the vertical line cannot be calculated after being determined by one position and need to be corrected again after being separated by a certain distance.

And thirdly, drilling the pre-buried fixing piece, drilling the pre-buried hole of the fixing piece according to the shot dividing line after the dividing line is shot and the recheck is correct, wherein the depth of the pre-buried hole meets the requirements of design and contractual agreement, and adjacent plates are staggered without deviating from the axis.

Fourth, the point adhesive density of the strong putty is not less than 60% of the plate area, the putty is not too thick, the putty is adhered too thick, the flatness is difficult to control, the plate stability is not easy to control, after the putty is constructed too thick, the back shrinkage can also influence the flatness of the plate surface, therefore, the adhering thickness of the strong putty is generally controlled to be 2-5mm, the thickness control is that the plate and the base are adhered together, the water is quickly collected, the plate is not shrunk after being installed and formed, the first and the last two plates are fixed when the plate is installed, then the stay wire is adhered, the horizontal surface and the vertical surface are communicated with the stay wire construction, the grid of the plate side edge line base is aligned with the horizontal construction line and the vertical construction line, the uniform width control of the grid line is needed during the construction, the expansion pipe installation and the screw fixation are carried out after the plate is installed and corrected stably, in order to prevent the flatness of the plate surface from being deformed in hand when the screw is tightened before the screw fixation, it is suggested to back-line some small hard material to control flatness distortion.

And fifthly, after one vertical construction surface is finished, filling foam strips in the dividing joints, wherein the foam strips are required to be densely filled.

Filling and scraping elastic sealant, wherein beautiful line adhesive tapes are adhered to two sides of the elastic sealant when the elastic sealant is filled and scraped, the vertical, horizontal and width are considered to be equal when the elastic sealant is adhered, the seam width is uniform and meets the design requirement, the sealant is densely filled, smooth radians are naturally formed in the formed dividing seams, the intersections of the longitudinal dividing seams and the transverse dividing seams form inner splayed characters, and the angles are clear.

Seventhly, tearing off the protection film, the protection film is forbidden to be torn off before not accomplishing all processes, finds the not hard up phenomenon of protection film during the construction, will in time paste with sticky tape paper, and the protection film tears off must bore all processes and all accomplish, and can tear off behind the consent of field management personnel, and the protection film tears off the back, and the year face cleans to the finished product of having under construction does the nurse work, and all working faces construction finishes and reports construction completion acceptance.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
