Structural system and method of prefabricated garage based on prefabricated piles

Abstract

The invention discloses an assembled type garage structure system based on precast piles and a method. The assembled type garage structure system comprises the precast piles, horizontal supporting beams and independent foundations, wherein vertical load bearing parts of a garage structure are formed by the precast piles, and guide rails are arranged on the outer surfaces of the precast piles; the horizontal supporting beams comprise ground beams and superposed beams, the ground beams are arranged around the precast piles by one circle so as to support a bottom plate of a garage, and the superposed beams are arranged around the precast piles so as to support a garage floor plate or a garage top panel; the independent foundations are connected with the precast piles and the precast ground beams through designed grooves. All the structure members such as the precast piles and the independent foundations are machined in factories and can be assembled for construction, so that emission of pollutants at a construction site is reduced; through the guide rails and cooperation of the independent foundations and mounting flanges, the perpendicularity of the precast piles is guaranteed, the structure bearing capacity is well guaranteed, and structure precision is guaranteed; the precast piles and garage columns are integrated, so that not only is energy saved, but also construction efficiency of the underground garage is greatly improved.

Description

technical field [0001] The invention relates to a basement structure, in particular to an assembled garage structure system and method based on prefabricated piles. Background technique [0002] The prefabricated structure refers to the structure in which structural components such as beams, columns, and slabs are prefabricated in the factory and assembled on site to form a force-bearing system. my country's urbanization process is accelerating, and the urban ground space is becoming smaller and smaller. The construction of underground garages relieves the pressure of ground parking. A large number of newly-built residential buildings and public buildings are equipped with underground garages. The garage generally adopts an independent foundation and a cast-in-place frame structure. According to the foundation conditions, an independent foundation with a large area is often used, and a waterproof base plate with a thickness of more than 250mm is installed at the same time, ...

AI Technical Summary

Problems solved by technology

According to the foundation conditions, an independent foundation with a large area is often used, and a waterproof bottom plate with a thickness of more than 250 mm is installed at the same time, and then the columns are tied with steel bars to pour concrete columns, etc. The result of this is that the site construction efficiency is low, the construction period is long, and a large amount of waste is generated. polluted environment

At the same time, when the local foundation soil is relatively weak and a large number of piles are needed to ensure the bearing capacity, it is difficult to guarantee the verticality of the pile body, which is unfavorable to the structural force; shallow, does not consider the role of the lower pile, and bears a small vertical load, which is not suitable for underground garages for residential buildings and general buildings; in addition, most of the cast-in-place components are non-prestressed components, which cannot make full use of the characteristics of the material. cause waste, which requires new research and design on the structural system and method of the prefabricated garage
