1、Because of the inconsistency of the location of the holes will affect the building's façade effect, and the location of the pre-embedded casing is difficult to fix, so the construction is recommended to use the reserved foam (150 * 150). 2, casing installation, the upper and lower floors should be hanging through the line will be installed in the plastic casing in place, and to ensure that the facade is neat and beautiful. 3, air conditioning through the wall hole slope to the outdoors, the general slope of 10%. 4, condensation drainage branch pipe is generally in the hole directly below the hole, from the center of the air conditioning through the wall hole for 200.

The role of through-wall screw is mainly to fix the template, so that the strength and steel of the template to improve, not to expand the mold. Shear wall penetrating screw has two kinds of cases: one is the basement shear wall with water-stopping penetrating screw; to be removed after the template, the water-stopping screw to protect the water-stopping iron piece of the plastic flared head removed, and then cut the screw at both ends of the tensile screw, with waterproofing mortar to make up for the flat, generally more than the concrete shear wall protrudes from the 5-8MM; the second case is used for the floor of shear walls in a plastic casing in the penetration of the screw, to be removed after the template will be extracted, for the upper turnover use, exterior walls or walls with waterproofing requirements for the wall of penetration of the screw. After the removal of the screw will be withdrawn for the turnover of the upper floor, the screw hole in the external wall or wall with waterproofing requirements must be removed with an electric drill to remove the plastic casing, and then block one side with a wooden wedge to avoid leakage, smoothed with micro-expansion concrete or waterproof mortar, or filled with special foam, and then the wooden wedge is withdrawn to make up for the leveling.

First of all, the new casing adopts a conical design (commonly known as the size of the head), in the process of concrete pouring, due to the role of the heat of hydration of the cement, the temperature of the concrete will rise to 40 degrees C ~ 60 degrees C, under the action of the temperature, the casing will be slightly expanded to a larger size, and when the temperature is lowered, the casing will be slightly reduced. When demolding, the actual casing is separated from the concrete, and the conical shape surface makes it easy to remove the casing from the concrete.
