Some common stone problems often occur in stone engineering, and many common problems cannot be solved well. Therefore, if you want to solve the problems, you must understand the causes of the problems, and then take preventive measures to solve them. This article analyzes the causes and preventive measures of the five common problems in stone engineering, hoping to help everyone!
01 FAQ 1: Pave the stone back net without removing it
Cause analysis
1) Insufficient awareness of quality and safety;
2) No disclosure or inadequate supervision and inspection.
Solutions (preventive measures)
1) Before paving, the back net shall be removed and coated with a protective agent, and the construction can be started after 24 hours;
2) For dry hanging stone, the back net of the dry hanging adhesive part must be partially removed.
02 FAQ 2: Fixation of the dry hanging stone keel and masonry wall is not standardized
Cause analysis
1) The node of deepening design is not clear;
2) No disclosure or inadequate supervision and inspection.
Solutions (preventive measures)
1) Fix with through wall bolts;
2) Fix it on the horizontal tie beam with expansion bolts.
03 FAQ 3:
The dry hanging stone is not provided with a vertical main keel or the main keel is not effectively fixed with the structural floor
Cause analysis
1) Insufficient awareness of quality and safety;
2) No disclosure or inadequate supervision and inspection.
Solutions (preventive measures)
1) Set vertical main keel and use wall bolts;
2) Fix it on the horizontal tie beam with expansion bolts.
04 FAQ 4: Dry hanging stone thickness is less than 32mm
Cause analysis
1) The thickness of finished large plates is generally thin;
2) Stone blocks are not used for planking.
Solutions (preventive measures)
1) If the thickness of the finished large plate does not meet the requirements, it must be cut separately;
2) Strengthen the management of material mobilization acceptance.
05 FAQ 5: The upside-down stone is not securely hung, which has potential safety hazards
Cause analysis
1) The stone is heavy, and the traditional technology is difficult to ensure safety;
Solutions (preventive measures)
1) Honeycomb aluminum composite stone;
2) Construction shall be carried out in strict accordance with standard nodes.
Stone engineering, safety first, so we must comply with various safety production specifications and systems.
