A frame building jacking device, an overall jacking method, and a jacking deviation correction method

Abstract

The invention discloses a frame building jacking device, an overall jacking method and a jacking deviation correction method, which include a jack, a screw rod, a threaded sleeve, an upper limit nut and a lower pressure nut; There are 2 or 4 corbels symmetrically arranged, and 1~2 threaded steel pipes are pre-embedded in each corbel; the jack is placed on the ground beam directly below the center of the frame column; the bottom end of each screw is pre-buried in the ground beam In the center, the top ends pass through the corresponding threaded steel pipes to form a piercing end, the maximum length of which is not less than the jacking height of the frame building; the thread fit clearance between the screw rod and the inner wall of the threaded steel pipe does not exceed 1mm; under each corbel Each screw rod is provided with at least one lower bearing nut, and each screw rod above each corbel is provided with an upper limit nut. The invention can reduce the number of jacks used, greatly reduce the number of pads used, and speed up the construction speed. At the same time, during the jacking process, the verticality accuracy is high, and it can prevent tilting.

Description

technical field [0001] The invention relates to the field of building jacking, in particular to a frame building jacking device, an overall jacking method and a jacking deviation correction method. Background technique [0002] Because the height of the building cannot meet the requirements of use, urban construction has led to a substantial increase in the outdoor ground and the elevation of the indoor floor is much lower than the height of the outdoor ground, etc., the building must be lifted to meet the use requirements. In addition, when the building tilts, it is necessary to lift the building to achieve deviation correction. [0003] When using traditional lifting construction methods for building lifting construction, there are often the following problems: [0004] (1) Traditional lifting devices and methods During the lifting construction process, each frame column requires multiple jacks, thereby increasing the use of jacks and greatly increasing the input cost.

AI Technical Summary

Problems solved by technology

[0004] (1) During the lifting construction process of traditional lifting devices and methods, each frame column requires multiple jacks, thereby increasing the use of jacks and greatly increasing the input cost

In addition, when a jack in a certain frame column fails, all the jacks in the group need to be replaced and checked one by one. Furthermore, a large number of spare jacks need to be prepared, further increasing the cost input

[0005] (2) The traditional lifting device and method use pads as the lifting support. When the lifting height is high, the support built with the pads has poor stability and is unsafe

In addition, when the height of the building is raised, the time-consuming period of the uplift is long. When using pads to build supports, etc., when encountering bad weather (such as the rainy season, etc.) or harsh environments (such as slight earthquakes, etc.), the frame load The verticality accuracy will be greatly reduced, and serious tilt will occur

[0006] (3) The traditional lifting device and method need to place jacks multiple times when adding pads during the lifting construction process, which makes the construction operation difficult

[0007] (4) The traditional lifting construction method has slow construction speed and long period
