1现浇楼板处楼面裂缝从住宅工程现浇楼板裂缝发生的部位分析,最常见、最普遍和数量最多的是房屋四周阳角处的房间在离开阳角一米左右,即在楼板的负弯矩筋以及角部放射筋未端或外侧发生45度左右的楼地面斜角裂缝;其它还有较常见的两类裂缝:一类是预埋线管及线管集散处发生裂缝,另一类为施工中周转材料临时较集中和较频繁的吊装卸料堆放区域的裂缝。现从施工角度进行分析,并分别采取以下几项主要技术措施:(1)加强楼面上层钢筋网的有效保护措施。楼面上钢筋网的有效保护,一直是施工中的一大较难问题。
A cast floor floor cracks at the site From the site of the cast-in-place floor cracks in residential engineering analysis, the most common, the most common and the largest number of houses around the sun at the corner of the room at a distance of about one meter Yang corner, that is negative in the floor Bending tendons and the corner of the radioactive bar at the end or outside of 45 degrees occurred on the ground floor bevel cracks; there are other more common two types of cracks: one is embedded pipe and pipe breakage cracks, the other Class for the construction of working materials temporarily more concentrated and more frequent lifting loading and unloading dump area. Now from the construction point of view of the analysis, and respectively take the following major technical measures: (1) to strengthen the effective protection of the upper floor reinforcement network protection measures. The effective protection of steel mesh on the floor has always been a major difficult problem in construction.
