Method for dismantling concrete of dustpan feeding inlet of constructional column

Abstract

The invention discloses a concrete removal method for a dustpan feed opening of a construction column, which comprises the following steps: installing a construction column formwork on both sides of a reserved construction column gap; installing the dustpan feed opening formwork on the top of the construction column formwork on one side; The concrete is poured into the formwork of the structural column through the formwork of the dustpan inlet, until the concrete poured from the formwork of the dustpan inlet is full and does not sink; before the concrete of the poured structural column is initially set, the pre-made post The formwork is evenly inserted into the formwork of the dustpan inlet from top to bottom along the formwork surface of the structural column; after the concrete of the structural column is finally set, the formwork of the structural column and the formwork of the dustpan inlet are removed in sequence; The concrete and post formwork are removed together; the post formwork is cleaned for the next use. The method is simple in operation, low in cost, and can be reused repeatedly. At the same time, it can well ensure the construction quality of the structural column concrete, improve the construction efficiency, and meet the requirements of green construction.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for removing concrete from a dustpan feed port of a construction column. Background technique [0002] The concrete of the structural column of the filled wall is poured after the masonry construction is completed, and the formwork of the structural column is generally assembled with wood plywood. Since the concrete of the structural column under the structural beam is difficult to pour and compact, it is necessary to set up a dustpan inlet to assist the concrete pouring of the structural column, and the height of the dustpan inlet is higher than that of the structural column. The concrete of the structural column is poured through the dustpan inlet, and vibrated as it is poured until the dustpan inlet is filled with concrete and does not sink, and the dustpan inlet is concreted and removed. At present, there are generally the following methods for the rem...

Problems solved by technology

[0005] The problems in the above methods are: ①. Affected by cement, admixture, ambient temperature, humidity and other factors, it is difficult to grasp the final setting time of concrete, which often leads to premature or too late demolition of the dustpan into the hopper concrete

If the concrete removal time of the dustpan into the hopper is too early, it is not conducive to the maintenance and strength growth of the structural column concrete. If the removal is too late, it will be difficult to remove; And the apparent quality of the concrete of the structural column cannot be guaranteed; ③. The concrete of the dustpan inlet is removed by manual sawing. Although the apparent quality of the concrete of the structural column can be guaranteed, the efficiency is low, the construction progress is affected, and it takes a lot of labor
