挑檐是建筑工程中常遇到的悬挑构件。挑檐板(或檐沟)常与顶层圈梁现浇在一起,其计算一般为三方面内容:挑檐板的强度计算、圈梁的强度计算(往往按构造配筋)以及挑檐的抗倾覆验算。在进行抗倾覆验算时,又常遇到下列情形:即在与屋面圆孔板平行方向取1延长米计算时,往往K=抗倾力矩/倾覆力矩<1.5。此时采取的措施,大都是在每道横墙上压入一段短梁(抗倾覆梁),使圆孔板压在短梁上,增加抗倾力矩,以满足计算需要。例如现在使用的部通用图(图号:房通1050),也是采用的这种办法。加了短梁以后,由于短梁的长度可以自由调整,短梁上
Provocation is a cantilevered component that is often encountered in construction projects. The provoking plate (or gutter) is often cast in place with the top ring beam, and its calculation is generally threefold: the strength of the provoking plate, the calculation of the strength of the ring beam (usually according to structural reinforcement) and the resistance of the provocation. Overturning checks. When carrying out anti-overturning checking, they often encounter the following situation: When taking 1 extended meter calculation parallel to the roof hole plate, K= anti-tilt torque/overturning moment is usually less than 1.5. Most of the measures taken at this time are pressing a short beam (anti-overturning beam) on each horizontal wall to press the circular hole plate against the short beam and increase the anti-tilt moment to meet the calculation requirements. For example, the department’s general-purpose map (figure number: Fangtong 1050) is now used. After the short beam is added, since the length of the short beam can be adjusted freely, the short beam is
