First-class constructor "building" exam handout: wall panel construction process

9, wall panel (brick) construction on the technical requirements of materials

(1) panel (brick) materials should be varieties, specifications, appearance and size acceptance. One of the indoor granite, paste with cement, ceramic tiles should be re-examined.

(2) the use of wet work method of construction of natural stone veneer should be anti-alkali, back coating treatment. Using the traditional wet work method of installing natural stone, due to the cement mortar in the hydration of the precipitation of a large amount of calcium oxide, flooded to the surface of the stone, resulting in irregular patches, commonly known as the phenomenon of alkali, seriously affecting the decorative effect of stone finishes. Therefore, before the installation of natural stone, the stone finish should be "anti-alkali back coating agent" for back coating treatment.

10, wall panel (brick) construction technology

(1) panel (brick) installation (paste) arrangement

mainly "seam arrangement" and "staggered arrangement" of the two.

(2) panel installation project

① stone panel installation: its installation method, in addition to the traditional wet work method, has developed a traditional wet work to improve the method (chiseling method), paste method. Stone veneer construction using dry hanging process, should be consistent with the technical requirements of stone curtain wall project construction.

②Metal panel installation: general use of keel installation, the keel is generally made of steel or aluminum profiles to support the skeleton.

③ wood veneer installation: generally use the keel nail installation, can also be used adhesive method.

④ Mirror glass panel installation: according to the principle of fixation is divided into two kinds, one is a (wood) keel installation method, the second is no keel installation method. Among them, there is a keel installation method of fasteners and fasteners set nail method and vigorously adhesive pasting method in two ways.

(3) the finish brick pasting project

Mainly using the traditional direct slurry (cement mortar, cement paste, etc.) pasting method, gluing method. External wall finishing brick paste project using full adhesive method of construction.
