Description

Steel construction roof beam hoist and mount levelling device Technical Field The utility model relates to the technical field of building construction steel structures, in particular to a steel structure beam hoisting and leveling device. Background The building is built in various places, the modeling of the building is increasingly complex and changeable, various innovative design concepts are layered, and the use of the steel structure is also increasingly wide. In this context, control of the quality of the steel structure installation becomes particularly important. According to incomplete statistics, in the steel structure construction process, two steel beams need to be horizontally butted, the steel beams are generally I-shaped steel, and in principle, when the two steel beams are butted, the upper flange plates and the lower flange plates of the two steel beams need to be horizontally aligned. However, there is a problem that after the installation of two adjacent steel beams is completed, the probability of occurrence of a height difference explosion point reaches 70%, and no convenient and reliable device is used for accurately adjusting the deviation of the steel beams in the market at the present stage. Disclosure of utility model The utility model provides a steel structure beam hoisting and leveling device, which solves the problem that the butt joint height difference of steel beams cannot be adjusted, and accurately regulates and controls the steel beams in the installation process so as to ensure the quality of engineering entities. The utility model is realized by the following technical scheme: The steel structure beam hoisting and leveling device comprises a jacking device and a positioning device, wherein the jacking device comprises a protective shell and a jacking device, and the upper end of the jacking device is fixed at the top in the protective shell; The positioning device comprises a device shell which is transversely distributed, a positioning cavity with a rectangular cross section is arranged in the device shell, the positioning cavity allows an upper flange plate of the I-steel to pass through, and a notch allowing a web plate of the I-steel to pass through is arranged at the bottom of the device shell along the length direction; The device is characterized in that a support is arranged in the device shell, the top of the support is connected with the bottom of the jacking device, and a third connecting plate is arranged at the bottom of the support. Further, the jacking device is a jack, the base of the jack is fixed on the top surface of the support, the top end of the jack is fixed on the top in the protective shell, The side wall of the protective shell is provided with vertically distributed long holes, and the operating rod of the jack extends to the outside of the protective shell through the long holes.
