Method for constructing added storey of building in jack-up manner through steel slide ways

Abstract

A method for constructing an added storey of a building in a jack-up manner through steel slide ways comprises the following steps of reinforcing a building original foundation (1); calculating required jack-up displacement of each frame column (2); arranging a steel bracket (4) on the periphery of each frame column (2); mounting a jack (5) below each steel bracket (4); completely sawing off each frame column (2) in a suitable range in which the frame column (2) is distant from a building foundation top surface (3) by using a rope saw and immediately inserting a thin steel plate in a fracture of each frame column (2) which is sawed off by the rope saw; arranging angle iron (6) to form steel slide ways (8); jacking up the sawed off frame columns (2) until the upper portions of the sawed-off frame columns are raised to an assigned height; and filling fine aggregate concrete in space between a portion, which is positioned below the upper portion of each frame column (2), of the corresponding steel slide way (8) and the lower portion of the frame column (2) to form a corresponding perpetual bearing column so as to construct the added storey of the building in the jack-up manner. Construction speed is high, manufacturing cost is low, and influences on a surrounding environment are smaller.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for jacking up buildings with steel slides, which belongs to the technical field of building storey addition and reconstruction, and is particularly applicable to the storey addition and reconstruction of multi-high-rise buildings. Background technique [0002] With the development and growth of the construction industry, the design concept of adding floors to buildings in modern society has become a topic that people in the industry generally pay attention to. Because the building has the advantages of not occupying land, less investment, quick results, and can quickly solve the problem of lack of housing, it is especially suitable for my country's national conditions. Therefore, in recent years, a large number of old houses have been renovated in our country, and good economic benefits have been achieved. and successful. [0003] The existing relatively common buil...
