SU1707158A1 - Lock for reinforcement - Google Patents

Abstract

The invention relates to the construction, in particular, to the reinforcement of closed contour elements, such as pipes, box sections, etc. The purpose of the invention is to combine individual flexible reinforcing strands into spatial frameworks and ensure their fixation in closed curvilinear shapes. The fixture fixture consists of two clamp-shaped elements 3 made of steel wire, connected by resistance welding, and contains loop-shaped units 4 for passing flexible reinforcement 2 through them. The ends of the fixture contain bends 5 directed parallel to the longitudinal axis of the form. A clamp through the loop-shaped units 4 is placed with a design step on the working straps of the reinforcement and fixed by crimping the loops perpendicular to the longitudinal axis of the frame. The skeleton thus formed is drawn into the closed form, while the bends 5 slide along the walls of the mold, preventing the flexible frame from turning, 3 sludge.

determines the number of latches in the frame and the step of their installation, based on ensuring the required value of the protective layer of concrete and preventing the working reinforcement from contacting the pipe wall. Flexible straps of reinforcement are passed through loop-shaped assemblies of clamps, by crimping assemblies with a design step and perpendicular to the frame axis, clamps

are successively fastened to the reinforcement, forming a spatial framework. Then the frame is tightened into a curvilinear closed formwork, with the bends 4 clamps sliding along the walls

formwork, while ensuring perpendicularity of the plane of the fixer installation relative to the longitudinal axis of the formwork and preventing the flexible framework from twisting inside the mold.
