Some common problems often occur in stone engineering, and many common problems cannot be solved well. To solve the problem, you must understand the cause of the problem and then take preventive measures to solve it. This article analyzes the causes and preventive measures of the five most common problems in stone engineering.
Common problem 1: Failure to remove the stone backing mesh before paving
Cause analysis
1) Insufficient quality and safety awareness;
2) Failure to hand over or insufficient supervision and inspection.
Solution (preventive measures)
1) Clean the backing mesh and apply protective agent before paving, and construction can be carried out after 24 hours;
2) Dry hanging stone must remove the backing mesh part of the dry hanging glue.
Common problem 2: The fixation of dry hanging stone keel and masonry wall is not standardized
Cause analysis
1) Unclear in-depth design nodes;
2) Failure to hand over or insufficient supervision and inspection.
Solution (preventive measures)
1) Use through-wall bolts to fix;
2) Use expansion bolts to fix on the horizontal tie beam.
Common problem 3: Dry-hanging stone has no vertical main keel or the main keel is not effectively fixed to the structural floor
Cause analysis
1) Insufficient quality and safety awareness;
2) No handover or inadequate supervision and inspection.
Solution (preventive measures)
1) Set up vertical main keel and use through-wall bolts;
2) Use expansion bolts to fix on the horizontal tie beam.
Common problem 4: Dry-hanging stone thickness is less than 32mm
Cause analysis
1) The thickness of the finished large plate is generally thin;
2) Stone blanks are not used for opening.
Solution (preventive measures)
1) The thickness of the finished large plate does not meet the requirements and needs to be opened separately;
2) Strengthen the on-site acceptance management of materials.
Common problem 5: The inverted stone is not firmly installed, which poses a safety hazard
Cause analysis
1) The stone is heavy and it is difficult to ensure safety with traditional technology;
Solution (preventive measures)
1) Use honeycomb aluminum composite stone;
2) Strictly follow the standard node construction.
