What is the installation method of marble door cover?

The effect of marble door cover is very high-grade and atmospheric. Compared with other products, marble has a very natural luster and stable performance. Even if it is used for many years, it is not easy to lose luster or scratch, so the application range of marble is very wide at present. A few years ago, marble door covers were often used in some high-end public places, such as elevators in hotels or supermarkets, but now many of them are used in home decoration. The following are the installation procedures and methods.

Construction preparation work

Material requirements: cement: No.325 ordinary portland cement, white cement: No.325 white cement; Sand: coarse sand or medium sand, screened before use; Stone: Prepare the materials according to the specifications and colors required by the design and drawings, and the surface is free of hidden damage, weathering and other defects; Other materials: such as plaster of Paris, copper wire or galvanized lead wire, lead skin, hard plastic strips and supporting pendants; With a proper amount of stone slag and mineral pigments close to the color of marble or polished granite and prefabricated terrazzo; 107 glue and special plastic hose for filling gaps in veneer, etc.

construction sequence

Glue brushing: when the base is wet, first brush a layer of 107 glue mud (107 glue mixture 10% water) and use the brush as the base; The bottom ash is made of 1: 3 cement mortar with a thickness of about 12mm, which is operated twice. After the bottom ash is compacted and leveled, scrape the bottom ash surface.

Drilling and slotting

Before installation, drill holes on the decorative board with bench drill according to the design requirements. Nail the wooden frame in advance, let the drill directly face the upper end face of each panel, and drill holes on the upper and lower sides of each panel. The holes are located at 1/4 at both ends of the panel width, and two holes are drilled on each face.

Binding steel mesh

First, the embedded steel bars on the wall are removed, and the parts of the wall are cleaned with marble or prefabricated terrazzo. Bending and pressing the tied vertical bars on the wall with embedded steel bars. Transverse reinforcement is bound marble or precast terrazzo and polished granite slab.

Broken line

First of all, marble or precast terrazzo, polished granite walls, cylinders, doors and windows should be hung with big lines from top to bottom to find out the verticality. The thickness of marble or precast terrazzo, polished granite slab, the gap between mortar pouring and the size of steel mesh should be considered.

fixed

Take the slate according to the position, straighten the copper wire or galvanized lead wire, put the slate in place, and tie the copper wire or galvanized lead wire at the lower mouth of the slate to the transverse bar. The cylinder can be installed clockwise, usually starting from the front. After the first floor is installed, use a ruler to find the verticality. After finding out the verticality, flatness and verticality, prepare the cooked gypsum with a bowl, and paste the gypsum made into porridge on marble or prefabricated terrazzo and polished granite board to make the two layers of slate integrated.

The above are the construction steps of the marble door cover, because the door cover is generally very high, so the installation effect is very important. If the installation is not firm, it will not only affect the effect of the door, but also easily fall off. Because the area of marble door cover is relatively small, a reasonable installation process is very important. Marble door covers are generally installed by professional workers. The service life is determined by the fineness of installation, so every working procedure should be carefully marked and checked to ensure the construction quality.
