发明名称 BLOCKING DEVICE FOR CONCRETE WALL FACE HOLE
摘要 PROBLEM TO BE SOLVED: To provide a blocking device for concrete wall face holes capable of blocking the wall face holes exposed on the wall faces when concrete walls are constructed simply and efficiently and capable of finishing the wall faces beautifully. SOLUTION: A form is fixed by a separator fitted with terminals at both end sections, then concrete is placed and hardened in the form, and the wall face holes generated on the concrete wall faces by the terminals when the form is removed are blocked by this blocking device. The terminals opened on the concrete wall faces are left in the concrete wall without being removed, and blocking plugs having the same size and shape as those of hollow insides are buried in the wall face holes formed by the hollow insides of the terminals.
