Problems solved by technology
Large box-shaped column-beams have the advantages of beautiful appearance, convenient installation, environmental protection and practicality, but due to the complicated manufacturing structure of box-shaped components, it is easy to cause distortion and deformation of box-shaped components during welding of box-shaped partitions, so it is difficult for production. Causes certain difficulties, especially for large box-shaped column beams that require high component verticality

Embodiment Construction
[0023] Below by embodiment, in conjunction with accompanying drawing, the technical scheme of the present invention is described further specifically, as figure 1 As shown, a high-strength box-shaped column distortion correction method on site, including a base, a lateral support, end fixed support and a lever mechanism, the base is composed of ground beams 1 arranged at both ends of the box-shaped column 11, in A hook fixture 8 and a positioning plate 3 are symmetrically arranged on the end of the box-shaped column on one side of the tire beam to fix the end of the box-shaped column as a fixed point for component correction; the tire beam on the other side is placed on At the bottom of the other end of the box-shaped column, two fixing fixtures 2 are set on the ground beam on this side to fix the box-shaped column and the lever beam 4 together. The lever beam 4 is made of existing box-shaped columns or H-shaped steel, according to The principle of leverage, use the fixed clam...

The invention provides a high strength box type column distortion and deformation on-site correction method. Firstly, distorted box type column is placed on two ground tire beams which are correspondingly parallel set, according to distorted condition, a fixing clamping fixture is arranged on one side of the distorted end of the box-type column, a subplate is placed on the other side of the distorted end of the box-type column, and a suitable lever beam is fixed to a correcting position of the distorted box-type column by using the fixing clamping fixture; then an electric calabash is installed at a suitable position of one end of the lever beam, the lever beam and the bottom ground tire beam are connected by using the electric calabash, by using a lever principle, by enforcing force to one end of the lever beam through the electric calabash, so that the lever beam and the connecting end of a box-type beam generate large enough reversed pulling force, thus a large torsion torque is obtained on the box-type beam; and finally, corresponded heating points are selected on the box-type beam so that heating can be conducted, when heating to a certain temperature, the function of the torsion torque can be used to adjust the distortion and deformation of the box-type beam. According to the high strength box type column distortion and deformation on-site correction method, material taking is simple, pertinence and adaptation are high, and the high strength box type column distortion and deformation on-site correction method is specifically suitable for rectifying box-type column andbeam on site where equipment lacks.
Description
technical field [0001] The invention belongs to the field of deformation correction of box-shaped column beams in building structures, and in particular relates to an on-site correction method for large-scale and high-strength box-shaped column distortion and deformation. Background technique [0002] With the development of my country's economy, the steel structure of high-rise buildings has been more widely used in China. At the same time, higher requirements have been put forward for the manufacture of steel structures. Box-type column beams have been widely used because of their economical and practical manufacturing. Large box-shaped column-beams have the advantages of beautiful appearance, convenient installation, environmental protection and practicality, but due to the complicated manufacturing structure of box-shaped components, it is easy to cause distortion and deformation of box-shaped components during welding of box-shaped partitions, so it is difficult for prod...
