FIELD: construction, particularly to create ornamental building facade. ^ SUBSTANCE: form panel is made as geometrical body with side walls and bottom provided with stiffening ribs and with orifices. Diaphragm of elastic porous material having three-dimensional ornament sections is connected to panel bottom. The panel has tray located from bottom thereof and including gasket to provide tray air-tightness. Panel also comprises jet to supply compressed air into space defined by bottom and lower diaphragm surface through orifices made in panel bottom and to pressurize above space. In accordance with the second embodiment diaphragm of elastic porous material having three-dimensional ornament sections is provided with through microscopic orifices communicated with the tray. The diaphragm is glued to the whole form panel surface area. Compressed air enters space between diaphragm and concrete to create excessive pressure in the space. ^ EFFECT: decreased force to be applied to form panel to release thereof from concrete surface. ^ 2 cl, 5 dwg |
