Installation and construction method of glass dome

glass dome structure In the connection between the main parts of the steel beam and the steel beam of the dome structure , the traditional construction method has two forms. One is the direct welding on site .   Second, the plate is fixed and then welded on site. C rane lifts the steel beam to the joint of another steel beam and the person welds it at high altitude and grinds it flat on site.   Both of the above two methods require welding operation, and on-site welding has the following disadvantages: 1) welding operation requires on-site welding machine to pull wires, which is of high labor intensity and slow construction speed, time-consuming and laborious, and also increases labor cost;2) high-altitude welding is dangerous, easy to cause casualties and cannot guarantee welding quality;4) due to welding deformation and errors, the lighting glass above cannot be processed correctly. Generally, the frame is welded and installed, and the glass is ordered and produced afte...

Bulk method for installation of  space frame 

图片
The installation of the space  frame is done in bulk.The operation process is as follows: setting out, checking the line, installing the lower chord plane grid, installing the upper chord inverted triangle grid, installing the lower chord positive triangle grid, adjusting, fastening, welding and acceptance of supports, checking the concrete strength of the column top, checking the specimen report. After qualified, the line setting and acceptance of the column top can be carried out at high altitude. Installation method of space frame : Before the space frame assembly unit node, the parts must be checked repeatedly, and the Numbers should be put in the seat in order.After each unit node is assembled, the tightening degree of the bolt shall be checked with the afterhand.After a certain area is installed, the lower chord is supported with temporary support to correct its lower chord elevation.After the installation of the entire network, re-check the fastening bolts, and remove ...
