The concerete hollow pint-sized block building is a new-style structural system in China. But some difficulties, such as wall heat preservation, wall cracks and secondary fitment, disturb the application of this structural system. We discuss temperature cracks on the wall, investigate the position and types of temperature cracks in the concrete hollow pint-sized block building, analyze the cause of temperature cracks, summarize the methods whic.h prevent temperature cracks in the world. Finally we try to solve the question about temperature c,racks through the more effective methods.
