Embodiment 1

[0057] Such as Figure 1~Figure 3 As shown, an integrated device for hoisting and installing steel trusses between arc-shaped roof sections, which includes two tracks that are respectively fixed on the installed sections of the roof and are parallel to each other and can be used for gantry frames and installation work platforms. The gantry moving above the curved roof, the installation work platform moving below the curved roof and the fixing device for adjusting the level of the track.

[0058] The gantry comprises a gantry beam 2 and a gantry column 3 arranged at both ends of the gantry beam 2; Both sides are provided with support rods 5, and the bottom of the gantry column sleeve 4 and the support rod 5 are provided with track wheels 6 that cooperate with the track 1; the gantry beam 2 is provided with an electric hoist 7. Two rails are installed on both sides of the curved roof section, and a gantry is erected on the rails; the gantry is equipped with an electric hoist, w...

Embodiment 2

[0074] A butt-joint hoisting method, using the above-mentioned hoisting device, hoisting the roof steel trusses using a separate hoisting method, a certain distance is reserved between the two trusses as the butt joints of the two steel trusses, and so on, every two trusses A butt joint is set between the trusses. After each steel truss and corresponding supports are hoisted, the steel members connected between the nodal points are hoisted one by one.

[0075] Hoisting method, it comprises the steps:

[0076] (a) On the steel trusses on both sides of the arc-shaped roof section (that is, the hoisted section 28), use the fixing device to fix the track and adjust the level of the track, and erect the gantry;

[0077] (b) Complete the assembly of the installation operation platform on the ground, lift the assembled installation operation platform on the ground from one end of the internode to the air through the gantry frame, move to the roof installation operation plane position...

Abstract

The invention relates to an arc-shaped roof internode steel truss hoisting and mounting integrated device. The arc-shaped roof internode steel truss hoisting and mounting integrated device comprises two tracks which are fixed to mounted nodes of a roof and are parallel to each other and through which a portal frame and a mounting operating platform walks, the portal frame moving above the arc-shaped roof, the mounting operating platform moving below the arc-shaped roof and a fixing device for adjusting level of the tracks. The invention also provides a hoisting and mounting method of the arc-shaped roof internode steel truss hoisting and mounting integrated device. The invention solves the technical problems that in the prior art, the arc-shaped roof internode steel truss is hard to hoistand mount in a butt manner precisely, the device cannot move flexibly, materials are hard to transport, the efficiency is low, the cost is high, the safety is low, the consumption of labor force is great and the like.

Description

technical field [0001] The invention relates to the butt joint hoisting construction of arc-shaped roof steel trusses, in particular to an arc-shaped roof internode steel truss hoisting and installation integrated device and a butt hoisting method. Background technique [0002] When installing curved roof steel truss structures and other high-height special-shaped structures, the method of hoisting by crane has many requirements on the construction site, especially when there are many roofs in the site that are temporarily supported, it is difficult for the crane to enter and exit the site. [0003] When the gantry crane is used for roof hoisting, the general gantry crane device is mostly placed horizontally. When the gantry crane is installed on the curved roof, because the curvature of the curved roof is different at different positions, there are different slopes. The traditional gantry crane is not easy to fix horizontally. At the same time, due to the low bearing capaci...
