Embodiment 1

[0012] Taking the installation of the ceiling keel of a hangar project as an example, the ceiling keel of this project is welded to the lower end of the roof grid ball through round pipes. The main keel is H-shaped steel, and the secondary keel is C-shaped steel; the primary and secondary keels are connected by bolts, and the installation height is close to +6m. Using the method of assembling and hoisting the ceiling keel into pieces, the specific steps are:

[0013] Step 1: Ground Assembly. When assembling on the ground, vertically project the layout of the primary and secondary ceiling keels under the high-altitude grid to the ground plane, and perform wiring positioning on the ground according to the projection. Lay the main keel in place, connect the primary and secondary keels with bolts, and complete the assembly of the ceiling keel.

[0014] The second step: hoisting to the elevation. When hoisting to the elevation, the four corners of the assembled ceiling keel are ...

Abstract

The invention relates to the field of installation of steel structures, in particular to a suspended ceiling keel sheet assembling and hoisting method. The suspended ceiling keel sheet assembling and hoisting method comprises two steps of assembling on ground and hoisting to elevation, and is characterized in that: in the process of assembling on the ground, primary and secondary suspended ceiling keels under a high-altitude net rack are vertically projected to a horizontal plane and then are assembled; and in the process of hoisting to elevation, lifting equipment is started to lift the suspended ceiling keels to the elevation, and then connecting rods for the suspended ceiling keels are fixedly connected with the net rack. The method reduces the risk in the process of mounting a high-altitude scaffold, and is accurate in positioning and higher in mounting speed.

Description

technical field [0001] The invention relates to the field of steel structure installation, in particular to a method for assembling and hoisting ceiling keels into pieces. Background technique [0002] The keel is the skeleton that must be built during the construction of many buildings. During the installation of the keel on the high-altitude ceiling, the traditional method is to erect the scaffolding to the installation level and install the keel one by one. After the large-scale installation is completed, deviations are easy to occur. The installation takes a lot of manpower, material resources, and time, and there are great security risks. Contents of the invention [0003] In order to overcome the defects of the prior art, solve the problem of high-altitude bulk installation of ceiling keels, and provide an installation method with high safety, fast installation speed and accurate assembly and positioning, the invention discloses a method for assembling and hoisting c...
