Description
Technical Field
The utility model relates to a plugging device of entrance to a cave is reserved to the outer wall, in particular to entrance to a cave plugging device is reserved to outer wall I-steel that can effectively restrain outer wall infiltration.
Background
In civil construction of high-rise buildings, I-steel overhanging scaffolds are mostly adopted, and a reserved hole is reserved on the outer wall of a primary structure wall body of the scaffold system for picking out I-steel to be used outside the wall; and after the scaffold which is chosen outwards is dismantled, plugging the reserved hole. The general plugging method comprises the following steps: reserving a rectangular hole with the width of 150 mm and the height of 250 mm at the position of an I-shaped steel of the outer wall of the overhanging layer, chiseling and washing the reserved hole after a scaffold is removed, erecting an inner template and an outer template at two sides of the hole, oppositely pulling and reinforcing the inner template and the outer template by using iron wires, pouring and blocking hole concrete at an opening on the template at the inner side of the wall, cutting the end part of the oppositely pulled iron wires after the concrete is solidified, and removing the inner template and the outer template; the disadvantages of this plugging method are: (1) the counter-pull iron wires left in the hole plugging concrete are easy to form a water seepage channel of the wall body; (2) the outside template of entrance to a cave shutoff concrete flushes the setting with the outer wall face, on the lateral surface of entrance to a cave shutoff concrete, makes the waterproof layer, can lead to the waterproof layer to bulge wall body outer wall face, influences the follow-up construction of outer wall face and pleasing to the eye.
