一、后浇带在设计中应明确的问题1后浇带缝宽,理论上后浇带宽度只须1厘米已足够保证温度收缩变形,但考虑施工方便,并避免应力集中,具体宽度应根据后浇带设置位置及砼厚度决定。2后浇带接缝形式有平直缝、阶形缝、企口缝等,接缝形式应加以明确。3后浇带内钢筋有断开搭接、贯通不断、增加附加筋3种。 A post-pouring tape should be clear in the design of a post-pouring with a slit width, in theory, after pouring tape width only 1 cm is sufficient to ensure temperature shrinkage deformation, but considering the construction convenience and avoid stress concentration, the specific width should be based on After setting the location and the thickness of concrete pouring decision. 2 after pouring with a straight seam seam form joints, step-shaped seam, tongue and groove joints, etc., the joint form should be clear. 3 After pouring the strip with a broken lap lap continued through, adding additional 3 kinds of ribs.
