Description
Technical field
The present invention relates to building comprehensive reformation technical fields, and in particular to a kind of foundation precast elements of assembled elevator and
Its construction method.
Background technique
The many existing buildings in China are built in the 80s and 90s, at that time due to being limited by factors such as economic conditions, build
Function is simple, and quality of life is poor, and seven layers and following existing building are all fitted without elevator.As urban life is horizontal gradually
It improves, the continuous improvement of economic condition, requirement of the people to quality of life is also higher and higher.Currently, the industry of these existing buildings
Main, especially old house owner is mostly old man, disabled person, and this kind of crowd's stair activity is highly inconvenient, this just constrains him
Trip and outdoor activities, dull, lonely animation is added to one piece of heart trouble to them.In order to solve these problems,
In the transformation of existing building, these old residential areas are built into the object being transformed for emphasis.In order to facilitate the daily life of resident
It is living, allow resident to live comfortably, conveniently, and do not have to put into a large amount of fund, the method that can use additional elevator, additional elevator needs
In addition elevator basis is added, reduces additional elevator structure to the mechanics influence of original structure.Existing elevator basic component is basic
All it is that scene digs pit and pours, conserves, carries out the installation of superstructure after waiting basic components to reach corresponding intensity again, process needs
Long time.
Under the premise of meeting construction quality, in order to shorten the construction period, speed of application is improved, construction cost is reduced, to existing
The basis of additional elevator is built using prefabricated basic component.Existing foundation precast elements are all directly primary in factory
Property pouring molding, then transport to erecting bed, directly lifting is mounted on the bed course of preprepared plus terraced position, however
Such molding basic component of primary concreting, all be need in advance measured size in erecting bed, then according to drawing into
Row accurately pours, and the basic component in later period is bulky not readily transportable, while very heavy, is also not easy to lifting installation, is lifted into
Behind erecting bed, it is also necessary to be fixed on basic component on bed course by implementing the work such as a large amount of welding, then backfill；And it is right
The very limited property processed of the selection in place, the molding basic component of primary concreting can not adapt to a variety of different places.
Summary of the invention
