Construction method and construction template for ultrahigh oblique concrete column

Abstract

The invention discloses a construction method and a construction template for an ultrahigh oblique concrete column. The construction method comprises the following steps: step 1, template selecting and configuring; step 2, rebar construction; step 3, template erecting and oblique column positioning; step 4, concrete pouring, wherein the oblique column concrete is poured by preferentially adopting a concrete auto pump, and tower crane transporting pouring is adopted for a place which cannot be poured by the auto pump; step 5, maintenance for the poured concrete. The construction template comprises a column template, an octothorpe hoop, an all-around scaffold and an independent support frame, wherein the column template comprises multiple template pieces with cambered structure; the octothorpe hoop is fixed at the periphery of the column template; and the all-around scaffold is supported on the bottom surface of a building, and the independent support frame is supported on the side face of the column template. The construction method and the construction template have the beneficial effects that through optimized selection of the template, a creative positioning method and a strictly-controlled pouring and vibrating operation process, the formed oblique column has a smooth surface, and the appearance quality is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building construction methods, and in particular relates to a construction method of a super-high inclined concrete column and a construction formwork used in the above method. Background technique [0002] With the development of the times and the progress of society, people's requirements for buildings are not limited to practical functions, but also increase the pursuit of artistic value, resulting in more and more special-shaped building structures, and the use of special-shaped components is also increasing. One of the more and more oblique columns. [0003] Due to the large inclination of the inclined column, the construction of the inclined column is the main difficulty in the construction of the project. Diagonal columns are difficult to support and concrete pouring. Concrete pouring is the most important thing in the construction of inclined columns. Due to the special shape of inclined columns...

AI Technical Summary

Problems solved by technology

Some inclined cylinders have a large slope and dense steel bars, so it is difficult for the vibrating rod to be transported to the bottom of the inclined cylinder. During the lifting process, the vibrating rod is easily caught by the stirrup

During the vibration of the inclined cylinder, the air bubbles generated in the concrete are not easy to discharge, and will accumulate under the top formwork, resulting in honeycomb and pitted surface of the top concrete, which affects the appearance of the concrete
