Cupulate foundation integral mould subsection casting one-step integral forming structure and forming method

Abstract

The invention discloses a cupulate foundation integral mould subsection casting one-step integral forming structure and forming method. In the traditional construction process, the position of a cup core offsets, results in axis deviation, small core internal mould supporting and arranging space, long construction time, and difficult cup core size guaranteeing. The cupulate foundation integral mould subsection casting one-step integral forming structure comprises a foundation framework, an internal mould component (7), and an external mould component (10), the foundation framework comprises anbottom frame (8) laid on a foundation cushion layer (18) and a cup core framework (2) fixed to the foundation cushion layer, the cup core framework is externally fixedly provided with a steel bracket(6), the external mould component is composed of a bottom template (9) fixed on the upper part of the bottom frame, an inclined plane template (1), and an outer template (4) fixed on the outer part of the steel bracket, and the internal mould component is fixed in the cup core framework. The forming structure is used for integrally forming cupulate foundation integral mould subsection casting inone step.

Description

Technical field: [0001] The invention relates to a cup-shaped foundation integral mold segmentally poured once integral forming structure and forming method. Background technique: [0002] A cup foundation is a type of freestanding foundation. When the upper structure of the building adopts a frame structure or a single-layer bent frame and gantry structure for load-bearing, the foundation often adopts a square or rectangular separate foundation, which is called an independent foundation or a column foundation. The independent foundation is the basic form of the foundation under the column; [0003] The cup-shaped foundation is a common foundation form for a single-story factory building. The traditional construction method of the cup-shaped foundation is divided into three steps. After the requirement, the concrete is manually applied to modify the slope, and the slope construction is completed. After the lower concrete solidifies and reaches strength, the upper cup core ...

AI Technical Summary

Problems solved by technology

[0005] ①. The position of the cup core is offset, causing the axis deviation;

[0006] ②. The support space of the inner mold of the cup core is small, the construction time is long, and the size of the cup core is difficult to guarantee;

[0007] ③ Multiple formwork support and multiple pouring caused quality problems such as large verticality deviation of the short column, substandard thickness of the steel bar cover, rotten roots at the joint between the short column and the large angle, poor perception of manual slope forming, and high labor-hour consumption
