An outer mold for integral demoulding of concrete tapered rods

Abstract

The invention belongs to the technical field of manufacturing of concrete conical rods, and particularly relates to an outer mould for integrally demoulding a concrete conical rod. The outer mould comprises an outer mould main body and a movable demoulding-assisting mould, wherein the outer mould main body consists of a conical sleeve, a flange I, a flange II and a small-end bar-hanging disc assembly; the movable demoulding-assisting mould consists of a steel plate conical barrel, a flange III and a big-end bar-hanging disc; the small-end bar-hanging disc assembly consists of a small-end bar-hanging disc main body, a tension rod and a locking nut; the tension rod is fixedly connected with the small-end bar-hanging disc main body; small-end grouting holes are formed in both the tension rod and the small-end bar-hanging disc main body; the locking nut is in threaded connection with the tension rod; the opening gap size is a fixed value at a big-diameter end, but a variable value at a small-diameter end. According to the invention, the structure of a forming mould is simplified, and a combined mould formed by two semicircle moulds is changed into an integral mould, so that the outer mould is easy to manufacture and low in cost; by virtue of an elastic function of a steel plate, the steel plate is skillfully rolled into the conical barrel, so that the demoulding becomes easier and quicker, and specialized mass production scale can be formed.

Description

technical field [0001] The invention belongs to the technical field of making concrete vertical poles, and in particular relates to an external mold and a construction method for integral demoulding of concrete tapered poles. Background technique [0002] The manufacture of traditional tapered concrete rods generally uses two semicircular molds to form a combined mold with a tapered inner cavity. There are two rows of mold openings fastened by bolts in the longitudinal direction of the mold. Close and close the mold opening of the mold. After pouring the concrete, the mold needs to be opened and demoulded. The process is cumbersome and the production efficiency is low. The outer surface of the mold opening of the finished product is rough and not smooth, and mechanized production cannot be realized.
