| Single-tier formwork | | A type of collapsible formwork containing, in its vertical section, a single panel only. The panel is kept in position by special bracing until concreting is completed and until removal of the forms is possible. Afterwards, the panel is removed and re-erected at the next position, its bottom part being fastened to anchors left in the concrete of th..... | | Similar Terms |

| Double-tier formwork | | A type of collapsible formwork containing two panels in the vertical section. The upper panel is erected on top of the lower, transferring its own weight and also the horizontal-lateral pressure of the concrete. The top of the panel is held in the required position during concreting by means of ties. After the concrete is set, the panel can be shif..... | | Similar Terms |

| Basic-type single-tier formwork | | Formwork consisting of panels with studs of a length equal to the height of sheathing. The studs carry two horizontal rows of anchor bolts, fastened to two corresponding rows of anchors embedded in the upper and lower parts of the panel. The anchors of the upper row remain in the concrete after removal of the panel and serve as panel supports for t..... | | Similar Terms |

| Cantilever-type single-tier formwork | | Formwork when the studs extend considerably below the panel sheathing. The stud extensions are provided with two rows of anchor bolts, fastened to two corresponding rows of anchors, embedded in the concrete of the previous block. This restrains the end of the stud and enables it to function, in effect, as a cantilever, subject to lateral pressure f..... | | Similar Terms |

| Walking-type double-tier formwork | | Formwork consisting of two identical panels connected by a bar hinged to the centres of the panels. The vertical shifting of the panels is achieved by a wailing action of the lower panel, that rotates with the bar, about the upper hinge while at the same time rotating 180o about its hinge so as to present its face towards the concrete (illustrated)..... | | Similar Terms |

| Double-tier formwork with sliding studs | | Formwork characterized by the fact that studs can be separated from the panel. Two horizontal rows of panels, standing one over the other, are held in position by vertical studs tightly fastened by means of tiers to anchors embedded within the concrete. As the level of concrete rises, the studs are lifted, and the panels, freed from the studs, are ..... | | Similar Terms |
