我们在黑龙江化工厂改扩建项目的混凝土框架结构模板施工中,采用胶粘法固定预埋件(主要部位在梁、柱侧面),收到良好的效果。具体施工步骤和注意事项如下。1.组装模板前,先将模板上预埋件位置处用水冲洗干净,擦干(此处不刷隔离剂)。2.将胶粘剂涂刷在模板预埋件位置处和预埋件表面,涂刷厚度不小于0.2mm。3.过5 min 后,将预埋件直接粘贴到模板上即可。
In the construction of the concrete frame formwork for the expansion and expansion project of Heilongjiang Chemical Plant, we used cementing to fix the embedded parts (main parts on the sides of the beams and columns) and received good results. Specific construction steps and precautions are as follows. 1. Before assembling the template, flush the surface of the pre-embedded part with water and wipe it dry (do not remove the isolating agent here). 2. Brush the adhesive at the position of the embedded part of the template and the surface of the embedded part. The brushing thickness is not less than 0.2mm. 3. After 5 minutes, paste the embedded part directly onto the template.
