Formwork-free constructional column and construction method

Abstract

The invention discloses a formwork-free constructional column and a construction method. The constructional column is arranged between two adjacent walls. The side faces of the two adjacent walls are connected through formwork building blocks. The formwork building blocks are laid layer by layer in the height direction of the constructional column. A steel reinforcement cage is arranged inside a columnar cavity defined by the formwork building blocks and the walls. The steel reinforcement cage and the walls are fixed through tying of tying pieces. Concrete is poured into the columnar cavity. The formwork building blocks and building blocks on the two walls are constructed at the same time. Combed joints need to be reserved when the first formwork building blocks are laid, the combined joints are retreated and enter successively, and the height of the combined joints is the height of the wall building blocks. Cleaning holes are reserved in one sides of the first formwork building blocks, and second and other formwork building blocks are laid according to the common construction method. The formwork building blocks are used for replacing a traditional formwork, and the working procedures of formwork erecting and disassembling are omitted; the formwork building blocks and the concrete of the constructional column can be firmly combined into a whole to bear stress jointly.

Description

technical field [0001] The invention relates to building construction technology, in particular to construction column construction technology. Background technique [0002] With the in-depth implementation of the national energy-saving policy, a large amount of various blocks are used in buildings, which have the advantages of saving cultivated land, light weight, good thermal insulation performance, convenient construction, high masonry work efficiency, and low cost of comprehensive projects, and are gradually being promoted. application. Setting structural columns in block filled walls is the main measure to improve the integrity of the wall and enhance the seismic performance of the wall, and has been widely used. [0003] The traditional construction method of the structural column needs to support the formwork, which has problems such as troublesome construction, easy mold runout, and grout leakage. In order to prevent grout leakage, double-sided adhesive tape needs t...

Problems solved by technology

[0003] The traditional construction method of the structural column needs to support the formwork, which has problems such as troublesome construction, easy mold runout, and grout leakage. In order to prevent grout leakage, double-sided adhesive tape needs to be pasted, which increases the construction process; Blocks, pouring core columns to replace the structural columns, but the core columns can only be inserted into vertical steel bars, and stirrups cannot be set, so that the shear capacity of the structural columns is much lower than that of traditional structural columns
