Anchor-Supported Foundation Formwork for Precise Concrete Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Forming a flat upper surface of a foundation at a predetermined height is difficult in conventional construction methods.
Innovation Solution
A method involving forming a foundation ground, installing reinforcing bars, setting formwork, arranging anchors along the formwork inner surface, and leveling concrete to match the formwork's upper end surface, with anchor supports fixed at higher positions to facilitate leveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional foundation construction methods are used, then the foundation can be constructed, but forming a flat upper surface at a predetermined height is difficult
Solution Approach 1:
The formwork is installed with its upper end surface positioned at the predetermined height before concrete pouring. This preliminary positioning of the formwork upper surface serves as a reference plane that guides the leveling process, making it easier to achieve the desired flatness and predetermined height of the foundation upper surface.
2Measurement precision
If anchors are arranged along the formwork inner surface, then anchor positioning is improved, but the leveling reference becomes less obvious
Solution Approach 1:
Instead of relying solely on the two-dimensional inner surface of the formwork for reference, the invention utilizes the three-dimensional upper end surface of the formwork as a prominent leveling reference. This upper surface extends beyond the formwork walls and provides a visible, accessible reference plane that is easier to use for leveling while the anchors are still positioned accurately along the inner surface.

AI summary
This foundation construction method for a building includes: a first step for creating a foundation base; a second step for installing reinforcement on the foundation base; a third step for installing a frame for creating a foundation to be provided to the foundation base; a fourth step for arranging a plurality of anchors so as to follow the inner periphery of the frame; and a fifth step for placing concrete inside the frame. In the fifth step, the concrete is leveled such that the upper surface of the concrete is the same height as the upper end surface of the frame.
