AI Technical Summary

Technical Problem

The existing cast-in-place independent concrete foundation requires carpenters to cut and support wooden formwork, which is time-consuming and labor-intensive, generates noise pollution, and requires tying edge reinforcement and erecting reinforcement, resulting in serious material waste, complicated watering and curing, and low construction efficiency.

Method used

The modular cast-in-place stepped independent foundation is adopted, using prefabricated side panels and truss structures, eliminating the need for carpentry to cut templates and support. A steel mesh is set up, eliminating the need for on-site binding and sealing of edges and erection of steel bars. It has lateral stiffness after pouring, allowing for backfilling of soil and direct construction of the superstructure.

Benefits of technology

It saves time and effort, reduces noise pollution and material waste, lowers construction costs, improves construction efficiency, simplifies watering and maintenance, and enables rapid soil backfilling and superstructure construction.

Abstract

This invention discloses a modular cast-in-place stepped independent foundation and its assembly method, relating to the field of building engineering technology. It saves time and labor, eliminates noise pollution, reduces on-site rebar tying and material waste, avoids chipped edges and corners, reduces watering and curing work, and saves costs. The key features are: the first-stage foundation frame is rectangular, enclosed by first-stage side plates; a horizontal first-stage truss is provided inside the first-stage foundation frame to support the lower and upper first-stage rebar meshes; the second-stage foundation frame is rectangular, enclosed by second-stage side plates; a horizontal second-stage truss is provided inside the second-stage foundation frame to support the upper second-stage rebar mesh; the second-stage foundation frame uprights are horizontally installed on the upper first-stage rebar mesh, and the upper column reinforcing bars vertically penetrate the first and second-stage foundation frames. This invention is used in cast-in-place concrete independent foundations.
