我们在用组合钢模板施工蓄水池、剪力墙时,为了穿对拉螺栓,普遍采用氧焊在钢模上刺一个孔,然后穿螺杆。这样一个工程完成后,会造成模极上多处存在孔洞,影响钢模板的完整性。对此,我们在某一主体工程电梯间剪力墙施工中,在模板中夹一条钢角模带,用角模上的孔洞进行穿螺杆固定。捣目混凝土的质量十分理想。这样做既不破坏模板,又节约刺洞材料和人工。接面及垫层的大面积混凝土施工,都要用平板振动器进行振捣。使用中,由
When we use the composite steel formwork to construct reservoirs and shear walls, we generally use oxygen welding to pierce a hole in the steel die and then wear the screw in order to wear the bolt. After completion of such a project, there will be many holes on the poles of the die, affecting the integrity of the steel formwork. In this regard, in the construction of a shear wall between elevators of a main project, a steel corner mold strip is clamped in a template, and a threaded hole is fixed in the hole in the corner mold. The quality of concrete is very good. Doing so will not destroy the template, but will also save puncture material and labor. For large-area concrete construction with joints and cushions, vibrators must be vibrated with a flat plate vibrator. In use, by
