Construction strategy of marble background wall

As one of the important elements of the home style, the TV background wall is made of stone with natural texture, which is both high-end and gorgeous and natural and environmentally friendly. However, the stone is relatively heavy and the upper wall is difficult to fix, so you need to be careful when constructing.

　　 Take the construction of a marble background wall as an example to teach you how to create a beautiful and safe TV background wall. There are glue sticking method and dry hanging method to fix the marble to the wall. In order to ensure a firm installation, more and more dry hanging methods are used in home improvement. The method of dry hanging is to install a steel frame on the wall and connect the marble slabs with fixings. Let's take a look at the specific construction process.

Marble background wall construction 1: processing the grassroots marking and positioning

First, we need to deal with the background wall base layer. The treatment method is not much different from the treatment of paving and pasting wall construction. Ensure that the wall is clean, free of floating soil and floating dust, and it has been leveled and coated with a moisture-proof layer. Then draw lines on the wall according to the construction drawings, and draw the overall horizontal line and vertical control line.

Marble background wall construction 2: install and fix steel keel

For heavy marble slabs, steel keels are needed to reduce the impact of the slate on the wall and improve the overall seismic resistance. The construction method is to drill holes in the wall to bury the fixing parts according to the construction drawings, and connect the keel to the fixing parts. The keel is required to be installed firmly and level with the wall.

Marble background wall construction 3: install the pendant to the keel

After the steel keel is fixed, the pendant connecting the marble slab needs to be installed on the keel. The shape of the pendant is like the shape of the letter T. Connect the pendant of T to the keel, and you can hang two pieces of marble; where there is only one piece of marble at the bottom, use a 45° pendant like the shape of 7. Just hang marbles.

Marble background wall construction 4: install marble slab

Connect the connectors, and then install the marble slab. The specific method is to cut the top and bottom of the four corners of each stone, inject marble glue into the mouth, and then insert the upper and lower cards of the connecting piece into the cut and fix it.

Marble background wall construction five: caulking treatment

After the marble slab is installed, the gap between the slab and the slab is glued. First, clean up the dust and impurities in the cracks, and stick tape paper on the edge of the board to prevent the glue from contaminating the marble surface. After the glue is applied, the glue joints are required to be smooth and straight.
