Prefabricated concrete L-shaped column cup opening foundation

Abstract

The invention discloses a prefabricated concrete L-shaped column cup opening foundation. The prefabricated concrete L-shaped column cup opening foundation comprises a prefabricated concrete cup opening foundation body, a prefabricated concrete L-shaped column, a foundation top welding reinforcing mesh, foundation bottom bidirectional reinforcing steel bars, fine aggregate concrete filler, local reinforcing embedded columns and a foundation cushion layer, wherein the prefabricated concrete cup opening foundation body, the foundation top welding reinforcing mesh, the foundation bottom bidirectional reinforcing steel bars and the local reinforcing embedded columns form a main body structure of the prefabricated concrete L-shaped column cup opening foundation body; and the prefabricated concrete L-shaped column cup opening foundation body is in a three-step shape in the vertical direction, and the overall plane is square. The prefabricated concrete L-shaped column cup opening foundation is an important component for achieving a middle- and low-riser full-assembly type concrete building system, direct socket connection of prefabricated vertical components is achieved, and a grouting sleeve connecting manner with the quality difficult to control is replaced. A foundation assembly can be machined in a factory and transported to the site to be hoisted and installed, the industrialization degree is high, and on-site installation is convenient; and the construction site is clean and tidy, the construction period is short, good economic benefits and social benefits are achieved, and the prefabricated concrete L-shaped column cup opening foundation is suitable for usage and popularization.

Description

technical field [0001] The invention relates to a cup foundation, in particular to a prefabricated concrete L-shaped column cup foundation, which belongs to the technical field of fabricated concrete structures. Background technique [0002] Prefabricated buildings are mostly used in high-rise residential buildings, but judging from the current application status at home and abroad, the use of fully assembled methods to build low-rise buildings can better leverage the advantages of prefabricated buildings. In recent years, concepts such as "new rural buildings, prefabricated villas, and military-civilian integration" have provided new opportunities for the development of mid- and low-rise prefabricated buildings. Compared with concrete structures, prefabricated steel structures and prefabricated wood structures have the advantages of convenient assembly in terms of structural systems, but their obvious shortcomings of high cost, poor durability, poor waterproof and fireproof...

AI Technical Summary

Problems solved by technology

[0003] The structural foundation generally adopts the method of cast-in-place construction, that is, most of the work from supporting formwork, binding steel bars to concrete pouring is done manually at the construction site. On the one hand, the labor intensity is high, the construction site is chaotic, and the consumption of building materials On the other hand, there is a lot of construction waste generated on site, and at the same time, it has a great impact on the surrounding environment. Based on this, this application proposes a prefabricated concrete L-shaped column cup foundation
