Problems solved by technology

The disadvantages of this technology are: 1. The inclined formwork of the structural column is complex and difficult to support, especially when the storey height is high
2. The concrete at the top of the structural column cannot be vibrated, and the fluidity and self-weight of the concrete itself cannot ensure the dense contact between the concrete at the top of the column and the floor.
3. The concrete at the bevel is removed after the formwork is removed, resulting in waste of concrete

Embodiment Construction

[0011] Structural drawings further illustrate the present invention.

[0012] Such as figure 1 As shown, the present invention is carried out according to the following steps: during the construction of the structure, the casing 1 is pre-embedded at the upper floor of the structural column position, and the exhaust pipe 2 is pre-embedded beside the casing 1, and the column top concrete passes through the pre-embedded The casing of 1 pours the concrete at the top of the structural column, and the air is exhausted through the embedded exhaust 2. The height of the casing and the exhaust pipe is the height of the structural beam or the thickness of the structural plate, and the casing and the exhaust pipe can be steel pipes, iron pipes and plastic pipes.

[0013] Such as figure 2 As shown, the formwork of the structural column is supported, the concrete on the top of the structural column is poured through the embedded casing 1, and the air in the formwork of the structural col...

Abstract

The invention relates to a constructional column top concreting method, which is characterized in that steps include embedding sleeves on an upper-layer floor slab at the position of a constructional column during structural construction, embedding exhaust tubes beside the sleeves, and concreting the top of the constructional column via the embedded sleeves during construction of the constructional columns. The heights of the sleeves and the exhaust tubes are equal to the height of a structural beam or the thickness of a structural plate. The constructional column top concreting method has the advantages that installation and concreting are convenient, and the concreting quality of the constructional column is improved. The problem of incompact concreting of the top of the constructional column is resolved.

Description

technical field [0001] The invention belongs to the field of engineering, in particular to a method for pouring concrete at the top of a structural column, which is suitable for secondary structure structural columns and core columns. Background technique [0002] At present, the concrete pouring construction technology for the top of the structural column of the secondary structure is: the formwork of the top of the structural column adopts an inclined formwork, the concrete is poured through the inclined opening, and the part of the concrete at the inclined opening is removed after completion. The disadvantages of this technology are: 1. The oblique formwork of the structural column is complex and difficult to support, especially when the storey height is high. 2. The concrete at the top of the structural column cannot be vibrated, and the fluidity and self-weight of the concrete itself cannot ensure that the concrete at the top of the column is in close contact with the f...
