There are many reasons for cracks in house walls, some of which are as follows:
a. Temperature difference cracks—forms include straight splayed cracks, inverted splayed cracks, horizontal cracks, etc.
b. Take the structure of a brick-concrete multi-storey house as an example. When the roof is a reinforced concrete slab and the wall is a brick wall, the wall is particularly prone to temperature difference cracks, especially on the top floor and the base of the parapet. department.
The severity of temperature difference cracks depends on the indoor and outdoor temperatures. It is related to construction quality, expansion joint spacing, roof insulation condition, window size, wall thickness, etc. ?
Relevant measures must be taken promptly to prevent, cure and repair these cracks.
