Description

Subgroups

Any liquid presses its lateral walls and fresh concrete puts hydrostatic press on surface of mold. Middle belt is used because mold may have necessary resistance against this pressure. Belts with two gears (دو سر دنده) are used for walls or sections such as shear walls in which hole of concrete doesn’t produce any problem and is variable proportional to thickness of wall and connect to vertical clamps by washer and nut. There is a case in which formwork is not possible behind wall or it is not necessary. In these cases, use of belt is not possible and anchor bolt shall be used instead. Despite belt which connects bilateral molds, anchor bolt is set inside mold and may be used after hardening previous concrete to tolerate lateral pressure of concrete on top. Anchor bolts are installed at the lowest section of wall in foundation. Vertical rafter of clamp, brocket and double jacks are other elements of unilateral mold of wall.
