Problems solved by technology
However, for the factory building columns made of reinforced concrete, it is difficult to fix the jacking rod on the reinforced concrete column, and even if the jacking rod is fixed on the reinforced concrete column, due to the fragility of the reinforced concrete material, when When the reinforced concrete column is cut off, first, the strength of the reinforced concrete column is greatly reduced, and second, it is easy to affect the connection between the jacking rod and the reinforced concrete column, thus easily causing the danger of loosening and falling apart during the jacking process, so the existing The jacking technology is only suitable for the roof lifting of steel columns, but not for the roof lifting of reinforced concrete columns.

Embodiment Construction
[0008] Embodiment of the present invention: jack can adopt hydraulic type or screw type jack, but preferably adopts screw type jack, when carrying out jacking to the roof of reinforced concrete column single-layer industrial factory building, earlier prefabricated spacer (6), The material of making spacer (6) can adopt plain concrete, reinforced concrete, timber or metal material to make, adopt plain concrete material to make under conventional circumstances, when making spacer, should notice that its upper and lower two planes are made smooth, The height is preferably made into the same height, then two reinforced concrete corbels (2) are fixed on the top two sides of every reinforced concrete column (1) of the reinforced concrete column single-layer industrial factory building, and each corbel ( 2) is a plane with the same height, place a jack (3) on the top surface of each corbel (2), and set a steel jack (3) at the bottom chord end of each roof truss (4) beam (5), and the ...

The reinforced concrete corbels are fixed on two side surfaces of upper portion of every reinforced concrete column of reinforced concrete column single-layer industrial factory building, on the top of every corbel a jack is placed, and a steel beam supported on the jack is placed on the lower chord end portion of roof trass, then the jacks can be synchronously started and the cushion blocks are added between the tops of all the reinforced concrete columns and lifted roof truss ends respectively, said operation can be repeatedly made, so that the roof can be lifted up to required height.
Description
Technical field: [0001] The invention relates to a method for integrally jacking up a reinforced concrete column single-layer industrial factory roof, and belongs to the technical field of integrally jacking up the roof. Background technique: [0002] The current existing roof overall jacking technology generally fixes the jacking rods used for jacking on the upper part of the uprights of the house, and then cuts off the uprights of the house before jacking up, as disclosed in the Chinese patent literature. It is: the overall jacking method of the top surface of a self-supporting house and its device, and the application number is: 01108408.1 technical scheme, in this technical scheme, the method adopted is exactly the method for jacking up after the house column is cut off. However, for the factory building columns made of reinforced concrete, it is difficult to fix the jacking rod on the reinforced concrete column, and even if the jacking rod is fixed on the reinforced con...
