FORM FOR CONSTRUCTION OF SLOPE FRAME

PURPOSE:To prevent a sprayed material from flowing out of the clearances on the underside of forms and provide a rigidity in such an extent that any troubles are not brought on placing concrete to prevent the forms from deforming and increase follow-up character and affinity with the ground. CONSTITUTION:An easily deformable metallic net is constituted of a lower frame 1 having a U-shaped section and a little smaller width than a slope width, a pair of right and left side frame members 3, 3 made of a welded net having a reverse U-shape section and fitted loose to the right and left erected pieces on even terms, and an upper frame composed of connection members 4, 4 jointing both side frame members 3, 3. And a plurality of preventive members 10, 10,... of deformation of the side frame are provided to fit to respective inside flange and the outside flange of the side frame member having a reverse U-shaped section and prevent the deformation of the opening between both flanges.
