The invention relates to construction industry, in particular, to modular formwork and a clamping device for connecting it. The modular formwork can be used for constructing walls and after hardening concrete mixture is disassembled completely and assembled anew for subsequent placement of concrete mixture. The modular formwork comprises panels, each in the form of rectangular box with a forming plate 1 and connecting profiles 2 forming side panels of the rectangular box structure, Each clamping device comprises a housing with a carrying element 6, rigid supports 7, a clamping plate 8 and an eccentric 9. The carrying element 6 of the clamping device housing has a rectangular section, the supports are made protruding in one transversal direction of the carrying element 6 along its lateral sides 10. The clamping plate 8 is hingedly connected on the carrying element 6 of the housing with clamp end projections being opposite supports 7 and positioning connecting bridge 12 on the other side of the carrying element 6. The eccentric 9 is mounted on the carrying element 6 from the side of the supports 7 capable to rotate and interact by its side working surface 13 with a side surface 14 of the connecting bridge 12 of the clamping plate 8. Radial projections 21, 22 and 23 are provided on the outer end surface of the eccentric 9. The projection 21 (fig.3) is oriented in the direction of maximum distance from the eccentric 9 rotation axis to the working surface 13, wherein projections 22 and 23 are oriented perpendicular to projection 21in opposite directions. |
