Locking pull rod structure of cylindrical die strengthening device

Abstract

The invention provides a locking pull rod structure of a cylindrical die strengthening device, mainly comprising a plurality of external corner protection elements, a plurality of internal corner protection elements, a plurality of pressing plate compacting elements, a plurality of groove fasteners, screw rods, and a plurality of locking pull rods, wherein every two locking pull rods are staggered with each other and the locking pull rods respectively surround the external corner protection elements, the internal corner protection elements and the pressing plate compacting elements outside; a locking hole is formed on one side surface of a body of each locking pull rod; the locking hole is connected with a locking hook to adjust the use length of the locking pull rod; a thickening element is arranged outside one side of (closes the locking hole) the body of the rod; a locking tongue groove is formed at the rear end of the same side of the locking hole; a locking tongue connected with the locking hook which is used for connecting and fastening the external corner protection element is arranged in the locking tongue groove; the pressing plate compacting elements are longitudinally fixed among a cylindrical die and the locking pull rods; the screw rods respectively penetrate through every two adjacent locking pull rods; and the groove fasteners, the screw rods and the locking pull rods are crossed and jointed with each other to strength the cylindrical die in a surrounding manner. The locking pull rod structure of the cylindrical die strengthening device is simple and convenient for operation, and also capable of improving the speed of mounting and demounting the cylindrical die; and as a result, the recycling is realized.

Description

technical field [0001] The invention relates to a cylindrical mold reinforcing device, in particular to a pull rod structure of the cylindrical mold reinforcing device which prevents the cylindrical mold from expanding and bursting due to the pouring of fillers. Background technique [0002] At present, the cast-in-place concrete column formwork in the construction industry is generally reinforced by materials such as plywood, square wood, steel nails, steel pipes, iron wires, screws, and column clamps. [0003] The general reinforcement method is to first nail the formwork to form a column formwork during installation, then nail dense nails at the corners of the formwork and combine iron wires to reinforce the corners to prevent grout leakage and form expansion, and then nail on the side of the square wood. Fix the square wood on the column formwork, and then tighten the pressure plate to fix it, then bind the steel pipe of the saw section with iron wires, combine the screw...

Problems solved by technology

[0005] With this method of reinforcement, more square wood, steel nails, steel pipes, and iron wires are used. Saw steel pipes and sawn square wood are more wasted and wasteful. Too much steel nails will directly nail the column formwork and shorten the column formwork. The number of turnovers; this reinforcement method is relatively complicated to operate, and the reinforcement, disassembly, and installation quality inspection of the cylindrical formwork are all labor-intensive, resulting in high costs and slow progress

Due to the sunlight and rain in the process of using the square wood, it is easy to deform and deteriorate, and the operation of the reinforcement method is complicated, and the workers are prone to mistakes and omissions in the operation. Defective phenomena affecting quality such as pockmarked surface and honeycomb
