When using fired bricks for wall construction,some cracks may appear due to improper operation and other reasons.If these cracks are not treated or preventive measures are not taken in a timely manner,it will pose a safety hazard to the building.So how can we prevent this situation during construction?
1.Before construction,it is necessary to consider that excavation for foundation construction must not damage the original soil of the foundation,and artificial foundations should be used for over depth excavation,with the foundation bearing capacity greater than the foundation bearing capacity.
2.The ratio of fired brick mortar should be adjusted in a timely manner based on the material conditions on site and changes in the material.If conditions permit,it is necessary to control the strength of the mortar while meeting the requirements of mortar workability.
3.It is necessary to strengthen construction management,improve the quality of fired brick masonry,ensure the fullness and thickness of mortar joints,control the moisture content of bricks,and strictly prohibit the occurrence of dry brick masonry or excessive watering of bricks during construction.When building the interior and exterior walls,it is necessary to try to achieve synchronous masonry and reduce the number of rubbing areas to improve the overall integrity of the house.
4.When there are load differences in various parts of the fired brick building,it is necessary to arrange the construction process reasonably.First build the heavy and high parts,then build the light and low parts,and first make the main part before building the ancillary parts.
5.The construction of the roof insulation layer should ensure the quality of loose insulation materials and control the thickness of the insulation layer.During construction,it is necessary to avoid high temperatures or cold seasons as much as possible,while also strengthening the maintenance,cooling,and insulation measures of fired bricks.
From the above,we can see how to prevent cracks when using fired bricks for wall masonry.It can also be seen that it is better to prevent cracks early rather than dealing with them when they appear on the wall.It can also improve the quality of construction and ensure the safety of buildings to a certain extent.
