Cast-in-place stair concrete pouring and tamping process
The invention relates to a cast-in-place stair concrete pouring and tamping process, and relates to the technical field of building construction, the cast-in-place stair concrete pouring and tamping process comprises the following steps: a template is supported to a preset position to form a cavity similar to a stair, the cavity forms a step part at each step, and two adjacent step parts are communicated with each other; concrete is poured, specifically, concrete is poured from the step part at the highest position, and after the step part at the highest position is poured, concrete is poured into the step parts at the lower positions in sequence, so that the cavity is filled with the concrete; vibrating: vibrating the concrete in each layer of step by using vibrating equipment so as to discharge air mingled in the concrete; curing: enabling the concrete to form strength; the formwork is dismantled, wherein the formwork is dismantled. According to the staircase, air mingled in concrete can be exhausted, the compactness of the concrete is improved, the cracking probability of the staircase is reduced, and the safety and reliability of the staircase during use are improved.
本申请涉及一种现浇楼梯混凝土浇捣工艺，涉及建筑施工的技术领域，其包括以下步骤，将模板支撑到预定位置，形成与楼梯相似的腔室，腔室在每个台阶处形成台阶部，相邻的两个台阶部之间互相连通；浇筑混凝土：从最高处的台阶部开始浇筑混凝土，待最高处的台阶部浇筑完成后，依次向在下的台阶部内浇筑混凝土，使混凝土充满腔室；振捣：使用振捣设备对每层台阶内的混凝土进行振捣，进而排出夹杂在混凝土中的空气；养护：使混凝土形成强度；拆模：将模板拆除。本申请能够排出夹杂在混凝土中的空气，提高了混凝土的紧实度，降低了楼梯开裂的概率，提高了楼梯使用时的安全性和可靠性。
