Mold for reinforcement framework stretching

Abstract

A mold for reinforcement framework stretching comprises a lower mold body, and multiple mold covers are hinged to the lower mold body through bearings. The hinge points are distributed in a left-rightstaggered manner, and the mold covers rotate around the hinge points to be opened or closed. The end faces of the mold covers are located through clamping blocks and clamping grooves, and each mold cover and the lower mold body are clamped left and right through a locking mechanism. Each locking mechanism comprises hinge seats arranged on the two sides of the lower mold body, and hooks are arranged on the hinge seats. A handle is arranged at one end of each hook. When the hooks rotate to the upper end, the hooks and connecting rods in the clamping grooves in the edges of the upper ends of themold covers rub to be locked. According to the mold for reinforcement framework stretching, by arranging the multiple hinge mold covers, the mold covers can be manually opened and closed, and the process is prevented from interfering with other procedures.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for stretching a steel bar skeleton. Background technique [0002] During the tensioning process of the steel frame, the upper and lower buckled molds are used to close, so as to realize the positioning and fix one end of the steel frame, so as to facilitate the prestressed tensioning of the frame at the other end. The traditional tensile test mold mainly includes an upper mold and a lower mold. The lower mold is fixed on the ground. The upper mold needs to be hoisted to the lower mold by a sling, and then locked and fixed by multiple bolts along the length of the lower mold. Since the steel frame is generally more than ten meters long, it is very cumbersome to install many bolts on both sides for each tension. In addition, every time the gantry spreader needs to be adjusted, the transfer is not only slow, but also other processes often need to use the gantry spreader, so there is a conflict of ...

Problems solved by technology

Since the steel frame is generally more than ten meters long, it is very cumbersome to install many bolts on both sides every time it is stretched.

In addition, every time the gantry spreader needs to be adjusted, the transfer is not only slow, but also other processes often need to use the gantry spreader, so there is a conflict of use, which affects the efficiency of each process
