Comparison of the advantages and disadvantages of dry hanging granite and traditional wet granite

Granite is a common decorative stone. In the past, the stone construction process mainly used the wet pasting method to operate. The wet pasting method mainly used the working surface to remove floating sand and debris, spread the cement mortar on the ground, and directly spread the bricks on it and level it with a leather hammer. Nowadays, we use the dry paving method to moisten the base layer with water, remove floating sand and debris, wipe the bonding layer, soak the bricks, use a one-to-three dry hard cement mortar, follow the horizontal line, and level the water-soaked bricks. Put it on the semi-dry cement and beat it with a sponge to squeeze out the bubbles in the cement. Take out the brick below, smear a thin layer of pure cement slurry on the back of the brick, and put the brick on the floor and shake it flat. Use this layer of cement slurry. Completely bond the floor tiles and the base of dry hard cement mortar together. This article compares the dry-hanging granite and wet-attached granite processes and analyzes the shortcomings of the new dry-hanging method.

Dry hanging granite is compared with traditional wet pasted granite;

(1) Different mechanical systems: it can be directly used on the external walls of high-rise buildings, dry-hanging granite can be directly fixed with hooks, and each wall can be individually stressed: wet-pasting granite can only be used in buildings with low heights The use of the wall surface mainly depends on the connection of cement slurry and steel wire.

(2) Wet-pasted granite is not stable, usually after the extreme heat and cold in summer and winter, it is easy to peel off and shell.

(3) Cement is prone to produce quality problems on granite walls and efflorescence during the process of humid air and heat of hydration. Compared with the glass curtain wall, the dry-hanging granite has coated glass on the surface of the glass curtain wall, which is easy to reflect light, causing environmental pollution; and compared with the dry-hanging granite, the glass curtain wall has poor heat insulation and heat preservation ability, which determines the high-rise or The super high-rise is decorated with dry-hanging granite materials.

At present, although dry-hanging granite has obvious advantages, there are still some problems that need to be solved. First, dry-hanging granite needs to rely on expansion bolts to transfer force to the concrete wall to achieve force transmission, which is the same as the traditional glass curtain wall using prefabricated iron. The method of force is different; secondly, the dry-hanging granite adopts the stainless steel connecting piece to transfer the weight of the granite to the concrete wall and the expansion bolt, which is easy to cause the deformation of the stainless steel connecting piece; then, the dry-hanging granite realizes the connection of the connecting piece through the pin The key to the construction of granite stone walls is the quality of the perforation, and its quality is related to the material of the granite itself. The increase in glue quality and stress of granite has a huge connection with the control of the seam of the stone curtain wall; finally, the control of the granite bonding compatibility and the quality of waterproof, sealing and weatherproof glue.
