AI Technical Summary

Technical Problem

In ultra-long prefabricated buildings, prefabricated columns cannot effectively match the prefabricated cup mouth foundation at the structural joints, resulting in too large spacing between the double prefabricated columns, affecting the building function.

Method used

A double column structure based on prefabricated cup mouth foundation is designed. By providing a partition in the prefabricated cup mouth foundation, the channel is divided into a first channel and a second channel, the verticality and spacing of the prefabricated column are adjusted using temporary support and the spacing pad, and the prefabricated column is fixed by high-strength grouting material.

Benefits of technology

The double prefabricated columns share a prefabricated cup mouth foundation, ensuring the controllability of the spacing between the double prefabricated columns, suitable for ultra-long buildings, and solving the problem of excessive spacing during the installation of prefabricated columns.

Abstract

According to the double-column structure based on the prefabricated cup foundation and the construction method of the double-column structure, a partition plate is arranged in a channel of the prefabricated cup foundation, a temporary supporting piece is arranged on the side face of a first prefabricated column, and a distance adjusting cushion block is installed on the side face of a second prefabricated column. And the prefabricated column at the joint cannot be matched with the prefabricated cup mouth foundation for use. The purpose that the double prefabricated columns share one prefabricated cup foundation on the premise that the distance between the double prefabricated columns is controllable is achieved, and the prefabricated assembly type design with the prefabricated cup foundation can be completely suitable for super-long buildings.
