Embodiment Construction

[0014] Such as figure 1 , 2 , 3, 4, a method for making concrete cylindrical formwork, including a corrugated pipe 1, a plurality of horizontal hoops 2 and a plurality of wooden vertical flutes 3, the corrugated pipe 1 is cut into two symmetrical pieces from the middle, so The horizontal hoop 2 includes an arc-shaped steel bar 1 4 and an arc-shaped steel bar 2 5. A plurality of movable sleeves 6 are sleeved on the arc-shaped steel bar 4, and both ends of the arc-shaped steel bar 4 are provided with threads. In section 7, nuts 8 are respectively sleeved on the threaded section 7, and welding sleeves 9 are respectively welded on the outer sides of the two ends of the arc-shaped steel bars 5. The two ends of the welding sleeve 9 have the same diameter, and the movable The two ends of the sleeve 6 have different diameters. The diameter of the thin end is smaller than the diameter of the nut 8, and the diameter of the thick end is larger than the diameter of the welding sleeve 9. The...

Abstract

The invention discloses a method for manufacturing a concrete cylindrical template. The method relates to corrugated pipes, a plurality of horizontal hoops and a plurality of vertical wooded keels. The two symmetrical corrugated pipes are well arranged in a cylindrical mode, the middle of each corrugated pipe is sleeved with the corresponding horizontal hoop, the vertical wooden keels are placed between the horizontal hoops in parallel to wrap the corrugated pipes, and the vertical wooden keels are sleeved with a plurality of horizontal hoops from top to bottom. According to the method, the cylindrical template is made from high-density polyethylene and has the advantages that the weight is low, the strength is high, the rotating rate is high, the inner surface is smooth, tenacity is good, and purchase transportation is convenient. The number of construction joints is small, flatness is high, contact between vertical joints is tight, and leakage is avoided. The template can be free of joint in the horizontal direction besides the two symmetrical joints in the vertical direction, the surface of poured concrete is smooth, color is consistent, roundness is accurate, and the vertical error is small. Forming is easy to achieve, assembly and disassembly are convenient, and work efficiency is high. Complicated external supporting systems are not needed, and maintenance and clearing are convenient to achieve after disassembly.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for making concrete cylindrical formwork. Background technique [0002] In order to meet the aesthetic needs of the public, concrete columns are widely used in building structures. The traditional cylindrical shaped steel formwork and wooden formwork support system can no longer meet the requirements of modern building construction. The appearance of the concrete cylindrical horizontal hoop corrugated pipe shaped formwork construction method overcomes many shortcomings of the traditional technology. Because the bellows column has light weight, good toughness, easy removal, and high flatness, it can meet the requirements of fair-faced concrete, thereby saving material costs, improving work efficiency and shortening the construction period. Summary of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art and ...
