Sliding plate type internal mold plate of thin-wall hollow pier with variable section

Abstract

The invention discloses a sliding plate type internal mold plate of a thin-wall hollow pier with a variable section and an installation method of the internal mold plate. The internal mold plate adopts a full steel mold plate, by means of a mode of built-in of a sliding plate and an adjusting mode in the steel mold plate with the variable section, the width and dimension of the variable section ofthe thin-wall hollow pier are adjusted to form an all-steel internal mode of the thin-wall hollow pier with the variable section. According to the installation method of the internal mold plate, theprocess is easy and convenient, the construction period can be effectively shortened and input of the labor and machinery is effectively reduced. According to the sliding plate type internal mold plate of the thin-wall hollow pier with the variable section, on the premise of satisfying the requirements of high quality construction, the problems of frequent cutting of the mold plate and poor appearance quality of concrete are solved, real work is well underway, meanwhile engineering quality safety is ensured, the working efficiency is improved, and the high market promotion value is achieved.

Description

technical field [0001] The invention discloses a slide plate type inner formwork of a thin-walled hollow pier with variable cross-section, which belongs to the technical field of inner formwork of hollow pier. Background technique [0002] The inner formwork of thin-walled hollow piers mostly adopts steel formwork and / or wood formwork and a mix of them. Steel formwork is often used for constant sections, and wood formwork is often used for variable sections. [0003] The disadvantage of wooden formwork is that it consumes a lot of precious wood, which is not conducive to environmental protection, and at the same time, the appearance of concrete is poor. [0004] Steel formwork and wooden formwork are mixed and used, and there are disadvantages such as cumbersome process, assembling formwork takes a lot of time, frequent cutting formwork material wastes more, and consumes a lot of labor. Contents of the invention [0005] Aiming at the above-mentioned problems, the present...
