Embodiment

[0025] In this example, the construction is carried out in the following steps:

[0026] 1. Before construction, the required column formwork 6, steel pipes and fixing cards for erecting the scaffold 5, and necessary tools such as adjustable wrench, hammer, pliers, woodworking saw, etc. should be prepared. And complete the preliminary work that meets the construction conditions. For example, the concrete pouring of the beam 1 and the steel pipe column 2 is completed, the strength reaches 1.2MPa, and the binding of the column reinforcement is completed. Clean up the site around the column root, open the pre-buried pouring hole; clean up the site near the pouring hole on the upper floor.

[0027] Second, set up scaffolding. The top view shape of the scaffolding 5 is a door shape, and the scaffolding is erected on three sides of the steel pipe column 2, and the vertical temporary entrance of the column formwork 6 is left on one side of the scaffolding. Bamboo raft slabs ...

Abstract

The invention discloses a method for pouring concrete outside steel pipe columns by using semicircular templates. The method comprises the following steps: constructing after concrete is poured in beams and the steel pipe columns of a building, the strength reaches 1.2 MPa, and column reinforcements are bound; reserving pouring holes in an upper floor when the beam and steel pipe column concrete is poured; when concrete outside the steel pipe columns is poured, firstly erecting a scaffold outside the to-be-poured steel pipe columns, assembling column templates by using the scaffold, wherein the column templates are semicircular wood templates or glass fiber reinforced plastics templates of which the lengths are different, fixing the column templates with steel strip hoops, forming pouring grooves between the tops of the column templates and the pouring holes reserved in the upper floor, and fixing and positioning the column templates through steel pipes connected to the scaffold; then pouring concrete outside the steel pipe columns by using self compact concrete; and finally, finishing pouring construction of the concrete outside the steel pipe columns through mould release and maintenance. The method disclosed by the invention mainly has the characteristics of smooth inner surfaces, precise roundness, high strength, easiness in moulding and convenience in assembly and disassembly.

Description

technical field [0001] The invention relates to a method for pouring concrete outside a steel pipe column by using a semicircular formwork, and belongs to the technical field of steel pipe column construction. Background technique [0002] At present, in various architectural designs in our country, a large number of cylindrical systems appear. Many construction units use traditional cylindrical shaped steel and wood formwork systems when constructing columns. However, this formwork system has many seams, time-consuming, high cost, and self Significant, inconvenient manual movement and other issues. Contents of the invention [0003] The object of the present invention is to provide a method for pouring concrete outside a steel pipe column using a semi-circular formwork to overcome the problems of many seams, time-consuming, high cost, heavy weight, and inconvenient manual movement in the prior art. [0004] Technical scheme of the present invention: [0005] The method ...
