A method for synchronous lifting and installation of equipment pipelines and large-span roof steel structures

Abstract

This application relates to a method for synchronously lifting and installing equipment pipelines and large-span roof steel structures, which belongs to the technical field of network frame installation, and includes the following steps: S1. Sequentially assemble the roof steel structures on the ground, and then install the supporting pipes The hanger is installed on the corresponding position of the steel structure of the roof; S2. Pre-install the pipeline segments on the support and hanger according to the pipeline segmentation plan, and temporarily fix the pipeline on the support and hanger; S3. Use the lifting tower to lift the The steel structure of the roof and the pipeline are lifted synchronously; S4. After the steel structure of the roof is lifted, the pipeline is adjusted, and the two adjacent pipelines are connected, and then the adjustment tool is used to adjust the height of the pipeline; the adjustment tool is adjusting the pipeline When the height is high, the temporary fixing of the pipeline can be loosened at the same time, so that the height of the pipeline can be adjusted; S5, after the adjustment of the pipeline height is completed, a wooden support is installed between the pipeline and the hanger to fix the height of the pipeline. The application has the effect of making it easier to adjust the height of the pipeline.

Description

technical field

[0001] The present application relates to the field of grid installation, in particular to a method for synchronously lifting and installing equipment pipelines and large-span roof steel structures. Background technique

[0002] In order to meet the needs of current building shapes and architectural functions, large-scale public construction projects such as airports and high-speed railway stations now use long-span steel structure roofs as the top frame of the buildings.

[0003] At present, the roof steel structure is usually assembled on the ground, and the pipes inside the roof are also pre-installed in the roof and installed with the overall lifting of the roof. However, after the lifting is completed and unloaded, the roof steel structure and pipes are prone to deformation. , resulting in the straightness and slope of the pipeline not meeting the requirements.

[0004] In view of the above-mentioned related technologies, the inventor believes that afte...

[0039] Attached to the following Figure 1-2 This application will be described in further detail.

[0040] The embodiment of the present application discloses a method for synchronously lifting and installing equipment pipelines and large-span roof steel structures. The synchronous elevation installation method includes the following steps:

[0041] S1, refer to figure 1 , first install multiple lifting towers on the ground, and the lifting towers are arranged according to the design positions; after the multiple lifting towers are installed, assemble the roof steel structure on the ground in the order of installation; while assembling the roof steel structure, The support and hanger 1 of the pipeline 2 is installed on the roof steel structure. The support and hanger 1 is prefabricated in advance. The support and hanger 1 includes a cross arm 12 and a vertical arm 11. The vertical arm 11 and the cross arm 12 are arranged perpendicular to each other. One end is welded and f...
