Embodiment 2

[0025] Embodiment 2, steel grid lifting equipment, the base 11 includes a rectangular support base 110, two inclined beams 111 are connected between the four corners inside the rectangular support base 110, and the intersection of the two inclined beams 111 is passed through a flange plate 113 is fixedly connected to the jack 12, with the axis of the jack 12 as the symmetric line, two mutually symmetrical jacking frame supports 112 are arranged on the two inclined beams 111, and the jacking frame supports 112 correspond to the standard section 21 of the lattice column up and down . The support 112 of the jacking frame is provided to support stably when the jack 12 falls back and when the jacking frame 2 raises the steel grid frame to the elevation, which not only facilitates the installation of the next lattice column standard section 21, but also facilitates the installation of the steel grid. The stable support after the top of the rack is raised to the elevation.

Embodiment 3

[0027] Embodiment 3, steel grid frame jacking equipment, each of the jacking frame supports 112 corresponds to the four bolt balls 210 below the lattice column standard section 21 up and down, and the jacking frame supports 112 and the bolt balls 210 are on top of each other The upper end surface of the joint is provided with a spherical groove having the same spherical radian as the bolt ball 210 . Setting spherical grooves can further ensure the stability of the support.

[0028] Other structures of this embodiment are the same as those of Embodiment 2.

Abstract

The invention discloses a steel truss jacking device. The technical problems that steel truss large hoisting equipment in a whole building group is unable to use, difficult to assemble, difficult in assemble quality and safety control in the prior art are solved. The steel truss jacking device comprises a jacking seat and jacking frames. The jacking frames comprise lattice column standard sectionsmatched with the jacking seat and bearing seats used for connecting the lattice column standard sections and the steel truss. The jacking seat comprises a base and a jack arranged on the base, a lifting seat is arranged at the top end of the jack, and the lifting seat is connected with the lattice column standard sections through pull rods. The steel truss jacking device has practical functions and convenient operation, and can complete the construction of the steel truss in the whole building group efficiently and safely.

Description

technical field [0001] The invention relates to the technical field of steel grid construction, in particular to jacking equipment for steel grids. Background technique [0002] For the large-scale hoisting equipment of the steel grid project located in the middle of the overall building group, it is difficult to use it close to it. It is difficult to select reasonable equipment for steel grid installation according to the site conditions, and it is also one of the key control points of this type of project. In addition, it is difficult to assemble the steel grid in situ at high altitude, and the assembly accuracy is also difficult to guarantee. Because of the cross-operation with civil engineering, when the scaffolding cannot be erected under the steel grid as an operating platform, the working conditions are poor and quality and safety control are difficult. However, existing devices for steel grid construction also have disadvantages such as complex operation and difficul...
