Pre-fabricated foundation structure of steel structure factory building

Abstract

The invention relates to a pre-fabricated foundation structure of a steel structure factory building, and belongs to the technical field of constructional engineering. The pre-fabricated foundation structure comprises pre-fabricated foundations and pre-fabricated foundation beams placed on the pre-fabricated foundations, wherein each of the pre-fabricated foundation comprises a baseplate with a rectangular bottom surface and an inverted tapered top surface and a short column on the baseplate; the cross section of each of short column is rectangular, and a rectangular groove is formed at the top of each of the short column; a plurality of annular vertical pore paths are arranged on the short columns, and the steel structure factory building is connected with the pre-fabricated foundations through the vertical pore paths via bolts; components of the pre-fabricated foundations are pre-fabricated in factories, transported to a construction site, positioned and installed, and after the pre-fabricated foundations are installed, the components on the pre-fabricated foundations can be installed immediately, so that the production efficiency is high, product quality is good, construction period is short, human resource is saved, and the foundations can be used repeatedly, which is favorable for green environmental protection and improvement of the steel structure factory building industry level.

Description

technical field [0001] The invention relates to a building foundation, in particular to a prefabricated foundation structure of a steel structure workshop, which belongs to the technical field of construction engineering. Background technique [0002] my country's economy is currently in a period of rapid development, and a large number of steel structure workshops need to be built every year. At present, most steel structure workshops in China adopt the cast-in-place reinforced concrete foundation structure with independent foundation under the column and foundation connecting beam. The cast-in-place reinforced concrete foundation usually adopts manual operation. The formwork is supported on the construction site, the steel bars are bound, the bolts are pre-embedded, the concrete is poured and cured, and the superstructure can only be installed after the foundation concrete reaches the design strength. The cast-in-place concrete foundation has the following disadvantages: ...

AI Technical Summary

Problems solved by technology

The cast-in-place concrete foundation has the following disadvantages: 1) Low production efficiency, long construction period, and a large amount of human resources; 2) The quality of the product is not easy to guarantee, and the pre-embedded bolts are prone to position deviation, which brings difficulties to the installation of the superstructure; 3) The foundation site The construction pollutes the environment heavily, and the foundation cannot be reused when the plant is demolished or relocated, resulting in construction waste, which does not meet the requirements of civilized construction and low-carbon environmental protection
