When decorating our homes, many families nowadays like to stick stones on the walls. Especially for rooms with large space at home. For example, when pasting stones on the walls of some villas or jump floors, it is indeed very floating. However, the installation of wall stone is different from that of ordinary wall tiles, because the thickness and specifications of wall stone are generally much larger than those of tiles, and the weight is also much heavier than that of tiles. So for the installation of large-sized stones, we need to pay special attention. In this article, we will provide a detailed explanation of the issues related to the installation of these larger sized stones.
1、 What does large-sized stone refer to?
If the stones are divided according to their side lengths, I personally classify them into two categories:
01. Some small sized stones have a side length of less than 400mm × 400mm.
02. For large-sized stone, the side length of this type of stone is greater than 400mm × 400mm.
2. We need to confirm based on the installation height of the stone.
For stone installation heights below 1000mm, we follow the conventional method for installation; If the installation height of the stone exceeds 1000mm, it is necessary to follow the installation method of the stone that will be introduced below.
II What are the specific procedures for installing large-sized stone materials?
Due to the large size and weight of large-sized stones, they must be installed using specialized installation methods. Here, we focus on distinguishing the installation method from ordinary stones, as ordinary stones are pasted using specialized marble adhesive or corresponding bonding materials. Large sized stones must be installed using different methods below.
The specific operation process for installing large-sized stone mainly includes the following steps:
The first step is to drill and groove the stone.
The second step is to wear copper wire or galvanized lead wire on the stone.
The third step is to bind the steel bars.
The fourth step is to snap the line.
The fifth step is the treatment of the stone surface.
The sixth step is grassroots preparation.
The seventh step is to install the stone.
The eighth step is grouting.
Common stones are marble and granite. The installation of stone can be completed through the above steps.
3、 How is drilling and grooving of stone carried out?
The first step is to use a table drill to drill holes according to actual requirements before preparing the decorative stone for installation.
Usually, a nail frame is used to align the drill bit directly with the upper end face of the board, and holes are drilled on the upper and lower sides of the door stone end face. The drilling position is generally at a distance of 1/4 from both ends of the board width, with 2 holes drilled on each side. The drilling hole has a diameter of 50mm and a depth of 120mm, and the most suitable distance from the back of the stone is 8mm.
The second step is our treatment of some special stones.
For example, when we choose a marble or granite board with a larger width, we need to increase the number of holes appropriately. This way, the eyelets can be connected, forming an elephant trunk edge for embedding copper wires underneath.
The third point is the treatment method for some decorative panel stones with larger specifications and sizes.
If the size of the panel is large and it is difficult to tie galvanized steel wire or copper wire below, we can use a portable small thin grinding wheel to cut a groove at 1/4 of the specified half height on the side that is adjacent to the decorative panel, with a width of 30mm to 40mm and a depth of 12mm. This way, it can be connected to the back of the decorative panel. This way, galvanized lead wire or copper wire can be placed in the groove, making it convenient for us to fix it with the steel mesh.
04. How can stones be threaded with copper wire or galvanized lead wire?
The first step is to treat the grooves for threading copper wire or galvanized lead wire.
We need to cut the prepared copper wire or galvanized lead wire into short segments of about 200mm, and stick one end of the copper wire or galvanized lead wire to epoxy resin with wood chips.
The second step is to bend the copper wire or galvanized lead wire along the hole nest at the other end and lie flat in the groove.
This can prevent the upper and lower ends of marble or granite slabs from protruding with copper or galvanized lead wires, making it easier for the stone to have a tight joint with adjacent stones.
5、 How to bind steel bars during stone installation?
The first step is to remove the embedded reinforcement on the wall and clean the area where the stone is embedded on the wall.
After preparing the above operations, you can start binding the steel bars.
The second step is to bind the steel bars.
When binding steel bars, first bind a vertical diameter of 6mm steel bars, and bend the bound vertical bars into the wall with embedded bars. Horizontal steel bars are used to bind marble or granite slabs.
Thirdly, let’s take a look at the specific requirements for stone fixation.
If the height of the board is 600mm, the first transverse bar should be tied tightly to the main bar at a position about 100mm above the ground, and the lower opening of the first layer of board should be covered with copper wire or galvanized lead wire.
The second transverse reinforcement is tied at a position of around 70mm to 80mm on a 500mm horizontal line, generally 20mm to 30mm lower than the upper opening of the stone material, which is used for binding the upper opening of the first layer of stone material. Fix copper wire or lead wire and tie a horizontal steel bar every 600mm upwards.
