In the latter case, orthostats are large thin slabs of gypsum neatly and carefully formed, for use as a wall-facing secured by metal fixings and carrying reliefs, which were then painted. Many orthostats were a focus for megalithic art, as at Knowth in Ireland. In the context of classical Greek architecture the term orthostate is usually used.
Walls are normally constructed to bulletproof standard at about 18 inches (46 cm) thick. [32] [33] [34] Pillbox type FW3/26, prefabricated construction. The type 26 also had an important prefabricated variant, in which the shuttering – both inside and out – was provided by precast concrete slabs slotted into reinforced concrete posts.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
A slab-trap is very much alike but more conclusive. Hunting with slabs is a system of hunting by means of a slab-trap. The fundamental part of the device is a slab. Preparing this trap was a delicate task. [7] [13] [14] Preparation of the trap: A slab of suitable dimensions is held in a raised position forming an appropriate angle with the ...
It is in sandstone, and consists of a rectangular slab on a stone base. On the slab is the incised life-sized figure of a man, and this is surrounded by a continuous inscription on four sides in English. Also on the slab are two more inscriptions in Latin.

Dutch gable, gablet: A hybrid of hipped and gable with the gable (wall) at the top and hipped lower down; i.e. the opposite arrangement to the half-hipped roof. Overhanging eaves forming shelter around the building are a consequence where the gable wall is in line with the other walls of the buildings; i.e., unless the upper gable is recessed.
Good lighting is important in a staircase so users see where they are going and to prevent falls. [6] There is often a window on the wall to let in daylight.In many cases, indoor stairs are placed far inside the building structure, and it is often not easy to get access to a wall on the outside where it would be natural to have a regular window for letting daylight in.
By reducing the weight of the slab without compromising its structural strength, it is possible to create a thicker slab to support more weight over a longer span. Hollow-core slabs , also known as voided slabs, initially appeared as one-way elements in Europe during the 1950s, and are still commonly manufactured in precast form for ...
