Concrete member internal mold capable of automatically stretching and contracting in radial direction

Abstract

The invention provides a concrete member internal mold capable of automatically stretching and contracting in radial direction. The concrete member internal mold is characterized in that a hollow cradle is vertically arranged at the center of an internal mold cylinder, connected with the inner wall of the internal mold cylinder by a connecting assembly, and at least provided with a second vertical rabbet which is close to an insertion plate and is over against the insertion plate; a vertical core plate of which the upper part is provided with a horizontal positioning plate is inserted in the cradle and in sliding fit with the cradle, the positioning plate is arranged at the upper end of the cradle, and the thickness tendency of the core plate and the width tendency of the second rabbet are consistent; at least one group of control assemblies capable of controlling the insertion plate to move along the radial direction of the internal mold cylinder and enabling the internal mold cylinder to stretch and contract in radial direction are arranged among the internal mold cylinder, the insertion plate and the core plate, the part in the control assemblies, connected with the core plate,moves up and down along the second rabbet, and the upper limit position of the moving stroke of the part is in the cradle. During the prefabricating of a concrete member, based on the cooperation of the internal mold and a conventional hoisting device, operation personnel do not need to climb in and out of the internal mold cylinder, mold assembling and/or mold stripping can be implemented easilyand conveniently, great convenience is provided for the production of enterprises, therefore the production efficiency of the enterprises is improved and the labor intensity of the operation personnel is reduced.

Description

technical field [0001] The invention relates to a radially self-scaling concrete member inner mold. Background technique [0002] The existing concrete component mold comprises an inner mold, a vertically arranged circular outer mold cylinder, and a horizontal base mold base plate. [0003] The structure of the inner mold is as follows: it includes a vertical insert plate, a circular inner mold cylinder body arranged vertically and with open upper and lower ends, and an axially arranged and through-shaped first cylinder body is opened on the inner mold cylinder body. The notch, the inserting plate is adapted to the first notch and placed in the first notch, the inner lower end of the inserting plate is provided with a horizontal load-bearing plate, the length of the load-bearing plate is greater than the width of the first notch, so that the length direction of the load-bearing plate The two ends exceed the first notch, and the inner wall of the inner mold cylinder is provi...

AI Technical Summary

Problems solved by technology

[0013] As mentioned above, it can be seen that the structural design of the inner mold is not reasonable. During the process of prefabricating concrete components, the operator has to turn in and climb out o
