在多层砖混结构房屋中,常出现程度不同的墙体温度裂缝现象。温度裂缝的产生虽与结构受力的安全度无关,但会影响结构受力的整体性,降低抗震能力。因此,采取措施,防止砌体结构产生温度裂缝是十分必要的。 一、裂缝的特点 温度裂缝一般产生于顶层屋盖或圈梁与墙体连接处,有水平裂缝、八字缝、斜向裂缝和垂直裂缝等。水平裂缝多发生在房屋两端的山墙、外纵墙上的门窗口上角、内横墙的屋盖或圈梁下一至二皮砖缝处;八
In multi-story brick-concrete buildings, there are often varying degrees of wall temperature cracks. Although the occurrence of temperature cracks has nothing to do with the safety of the structure, it will affect the integrity of the structural stress and reduce the seismic capacity. Therefore, it is necessary to take measures to prevent temperature cracks in the masonry structure. First, the characteristics of cracks Temperature cracks generally arise in the top roof or ring beam and wall joints, there are horizontal cracks, eight character seams, oblique cracks and vertical cracks. Horizontal cracks occur at the gables at both ends of the house, the upper corner of the door window of the outer vertical wall, the roof of the inner horizontal wall, or the seam between the next and the second lining;
