Panel sandwich for setting concrete of e.g. pillars, during construction of e.g. industrial building, has two laminated plaster panels formed in rectangular shape and separated from each other at equal distance of specific meter

Abstract

The sandwich has two laminated plaster panels (1) formed in rectangular shape and separated from each other at equal distance of 30-60 mm. An outer panel is covered with an inner paper layer and an outer paper layer. Perforations are uniformly distributed on inner surfaces of the laminated plaster panels. A reinforced concrete (2) is filled in an interstitial space of the sandwich. An armor of steel reinforcement is provided with reinforcement rods and columns (4) at diameter of 3-6 mm. USE - Panel sandwich for setting a concrete of pillars and girders during construction of industrial and commercial buildings. ADVANTAGE - The laminated plaster panels quickly absorb water and humidity contained in grazes of cement during construction process in a simple manner, reduce phase setting and improve runtimes and yield of a concrete structure. DESCRIPTION Of DRAWING(S) - The drawing shows a perspective view of a panel sandwich.Laminated plaster panels (1)Reinforced concrete (2)Columns (4)Plaster plates (5)
