Shear wall cylindrical formwork reinforcing device and using method

LI LINFENG / GAO WEIGANG / ZHOU QING

The invention discloses a shear wall cylindrical formwork reinforcing device and an using method. The shear wall cylindrical formwork reinforcing device is manufactured by machining angle steel waste,screws and cylindrical formwork reinforcing straps on a construction site, manufacturing is easy, the shear wall cylindrical formwork reinforcing device is suitable for reinforcing shear wall cylindrical formworks of various sizes, the shear wall cylindrical formwork reinforcing device can be efficiently and repeatedly used, the radians of arc-shaped straps in the device can be adjusted through the screws so as to meet the fastening requirements of column formworks with different diameters, when materials are selected, angle steel is selected as a stress framework of the reinforcing device, certain rigidity of the angle steel is used for resisting the impact force on the formworks during concrete pouring and the side pressure on the formworks in the concrete plastic state, when the devicestrengthens the formworks, 45-degree corner cutting treatment is conducted on the edges of the formworks at the joint of a column formwork and a wall formwork, so that the formworks are tightly spliced, when the formworks are installed, the formworks are installed in the mode that the column formwork presses the wall formwork, and the problem of concrete grout leakage at the position is completely eradicated.

本发明公开了一种剪力墙处圆柱模板加固装置及使用方法，本方法利用施工现场角钢废料、螺杆、圆形柱模板加固箍带加工制作而成，制作简单，适用于多尺寸的剪力墙处圆柱模板加固，能够高效反复使用，该装置中弧形箍带的弧度可通过螺杆进行调节，以满足不同直径的柱模板紧固，因材料选用时，选用角钢作为加固装置受力骨架，并利用角钢一定的刚性，以此来抵抗混凝土浇筑时对模板的冲击力及混凝土塑性状态下对模板的侧压力，该装置在加固模板的同时，对柱模及墙模接缝处的模板边缘做45°切角处理，使得模板拼缝严密，模板安装时，采用柱模板压墙模板的方式进行安装，杜绝了该部位混凝土漏浆的问题。
