Stair three-step bottom die reinforcing device, reinforcing supporting system and construction technology
The invention relates to a stair three-step bottom die reinforcing device, a reinforcing supporting system and a construction technology. The stair three-step bottom die reinforcing device comprises asteel plate, bolts and nuts. The steel plate is provided with two or more through holes, and the centers of all the through holes are located on the same straight line L1. The distances h1 from the centers of the through holes in the two ends of the straight line L1 to the edge of the steel plate in the direction of the straight line L1 are equal, and h1 is larger than or equal to 80 mm and smaller than or equal to 150 mm. The distance d1 from the center of each through hole to one edge of the steel plate in the direction perpendicular to the straight line L1 is smaller than the distance d2 from the center of each through hole to the other edge of the steel plate, d1 is larger than or equal to 150 mm and smaller than or equal to 200 mm, d2 is equal to d1 plus c, c is the distance from thecenter of each through hole to the boundary of stair three-step cast concrete in the direction perpendicular to the straight line L1, and c is larger than or equal to 80 mm and smaller than or equalto 120 mm. The steel plate is located under a bottom die and is attached to the bottom die, the bolts penetrate through the through holes in the steel plate and the bottom die to extend to the upper portion of the bottom die to be in threaded connection with the nuts, and the nuts wrap the portions, extending to the upper portion of the bottom die, of the bolts. The stair three-step bottom die reinforcing device enhances the formwork supporting rigidity, improves the stair three-step concrete forming quality and prolongs the service period of formwork.
本发明涉及一种楼梯上三步底模加固装置、加固支撑体系及施工工艺，所述的楼梯上三步底模加固装置包括钢板、螺栓和螺母；钢板开有两个以上的通孔，所有的通孔中心位于同一直线L1上，直线L1两端头的通孔中心沿直线L1方向到钢板边缘的距离h1相等且80mm≤h1≤150mm，通孔中心沿垂直于直线L1方向到一侧钢板边缘的距离d1小于到另一侧钢板边缘的距离d2且150mm≤d1≤200mm，d2=d1+c，c为通孔中心沿垂直于直线L1方向到楼梯上三步浇筑混凝土的界线的距离，且80mm≤c≤120mm；钢板位于底模的下方且紧贴底模，螺栓穿过钢板上的通孔和底模伸至底模上方与螺母螺纹连接，螺母包住螺栓伸至底模上方的部分。该楼梯上三步底模加固装置增强了模板支撑刚度，提高了楼梯上三步混凝土成型质量并且延长了模板的使用周期。
