用于防撞墙的模板不宜采用小块组合式钢模板
用于防撞墙的模板不宜采用小块组合式钢模板,而应采用大块钢模板。这是因为模板越小, 接缝越多,外观越差,而且接缝处表面不易平整,也易出现漏浆现象。控制钢筋保护层厚度 可使用小石块来填隔钢筋,不宜采用混凝土垫块,以免在拆模后墙体表面出现一块块难看的斑痕,立模时,在防撞墙侧模的顶部与底部分别安装一根用槽钢制作的横带螺丝杆固定。然后,在两侧的槽钢上均匀地安装几根钢支撑杆,使模板的整体得到固定。
The small combined steel formwork should not be used for the formwork of the anti-collision wall, but the large steel formwork should be used. This is because the smaller the formwork, the more joints, the worse the appearance, and the surface of the joint is not easy to be flat, and also prone to leakage. To control the thickness of the protective layer of the reinforcement, small stones can be used to fill the steel bar, and the concrete cushion block should not be used, so as to avoid the unsightly spots on the wall surface after the formwork removal. When erecting the formwork, a transverse belt screw rod made of channel steel shall be installed at the top and bottom of the side formwork of the anti-collision wall for fixation. Then, several steel supporting rods are evenly installed on the channel steel on both sides to fix the whole formwork.
2 混凝土质量控制
2. Concrete quality control
由于防撞墙底宽上窄,其内部的钢筋布置较密,浇注混凝土施工时不利于排除气泡,所以对混凝土的和易性有较高的要求。
Because the bottom width of the anti-collision wall is narrow on the top and its internal reinforcement arrangement is relatively dense, it is not conducive to eliminate air bubbles when pouring concrete, so it has higher requirements on the workability of concrete.
