Prefabricated assembly type steel reinforced concrete independent foundation under column

Abstract

The invention provides a prefabricated assembly type steel reinforced concrete independent foundation under a column. The independent foundation is sequentially provided with a self-setting plain concrete cushion layer, a cement mortar leveling layer, a bottom-layer steel reinforced concrete prefabricated block, a middle-layer common concrete prefabricated block, an upper-layer common concrete prefabricated block and a prefabricated steel base plate from bottom to top; and a prefabricated steel column is perpendicularly welded on the prefabricated steel base plate, and the self-setting plain concrete cushion layer, the cement mortar leveling layer, the bottom-layer steel reinforced concrete prefabricated block, the middle-layer common concrete prefabricated block, the upper-layer common concrete prefabricated block and the prefabricated steel base plate are fixed into a whole through anchor bolts and nuts. According to the adopted assembly type steel reinforced concrete independent foundation under a column, block bodies are prefabricated in a factory, the weight is light, the precision is high, and the manufacturing quality is easy to guarantee; the block bodies are meshed with one another in a layered mode, the bolts are adopted for connection, so that disassembling and assembling are convenient, and the repeated utilization rate is high; and the block bodies can be manuallycarried, large construction machinery is not needed, so that flexibility and convenience are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an independent foundation under a prefabricated assembled steel concrete column suitable for low-rise and multi-storey assembled light steel frame structure buildings with small upper loads. Background technique [0002] With the development of my country's social economy, in the construction process of building foundation projects, problems such as tight construction period, high labor cost, long concrete maintenance and formwork turnover period have become the bottleneck factors affecting the development of building industrialization. In China, the independent foundation under the column mainly adopts the form of cast-in-place reinforced concrete foundation. With the promotion of building industrialization in the country, the cast-in-place method seriously hinders its development: the cast-in-place reinforced concrete foundation needs to go through construction ...

AI Technical Summary

Problems solved by technology

The system has all foundations and other components that can be prefabricated according to building modules, so the foundation specifications and quantities can be directly selected according to the bearing capacity of the foundation. The entire system is installed in a fully assembled manner, which greatly shortens the construction period, but at the same time has the installation accuracy of each component. The requirements are high, the construction process is cumbersome, and the stability of the foundation against punching shear and horizontal slip is not easy to guarantee, etc.
