Problems solved by technology
During the prefabrication of the entire piece, the installation sequence of each member must be reasonably planned in advance for the construction process and process, otherwise, the prefabrication of the bolted member will not be installed normally, and the bolted member will be easily repaired, resulting in a waste of resources

Embodiment Construction
[0046] Such as Figure 1-Figure 13 Shown, the present invention adopts following steps:
[0047] The first step: if figure 1 As shown, after the main beam 1 is cut according to the actual size, the first main beam stiffener plate 12 is installed on the flange where bolt holes need to be opened on the inner side of the shaped steel by welding; then, the second bolt hole needs to be opened outside the shaped steel The second main beam stiffener plate 13 is placed in the installation position; then the first main beam stiffener plate 12 and the second main beam stiffener plate 13 are drilled together with the main beam 1 flange, and the second main beam stiffener plate 13 Use four temporary ordinary bolts to install and fix on the main beam 1 flange, and apply 100% torque;
[0048] The second step: if figure 2 As shown, several main stiffeners 11 arranged on the main girder 1 are prefabricated into a small whole; since the main stiffeners 11 are spliced by several steel pla...

A piece prefabrication process with bolted rods, which adopts the following steps: 1: install the rib plate on the flange of the main beam; 2: prefabricate several main rib plates into a small whole; 3: assemble several main rib plates Install the rib plate on the main beam and complete the prefabrication of the main beam; 4: Combine the main beam and the secondary beam into a horizontal layer; 5: Level the horizontal layer and place it on the pier; 6: Install the rib plate At the positions of the columns on both sides; 7: Fix the stiffeners on the columns; 8: Install the columns on both sides and temporary oblique supports; 9: Install the horizontal supports between the columns and perform anti-corrosion treatment; 10: Install the railings and Wrap the contact surface of the horizontal support; eleventh: anticorrosion of the slices; step twelve: install the temporary diagonal support between the main beam and the column to complete the prefabrication of the slices. The invention solves the problem of prefabricated installation accuracy of rods connected by bolts, greatly improves the prefabricated efficiency of deck pieces, and reduces the installation cost of nodes.
Description
technical field [0001] The invention relates to the prefabrication process of the slices in the modules, in particular to a prefabrication process of the slices with bolted rods used in the land construction stage of the modules. It belongs to the field of offshore oil engineering. Background technique [0002] At present, the large-scale modules completed at the construction site of offshore oil structures, land liquefied natural gas (LNG) modules and solvent deasphalting core production process modules are usually prefabricated by dividing the structures into horizontal layers one by one , and then, welded again to form a whole. For prefabrication of pieces, the order of the rods will not have a great impact on the construction of the entire project. After each piece is prefabricated as a basic unit, it is first transported to the sandblasting and painting workshop to complete the spraying work, and then transported to the final assembly site to complete the final assemb...
