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 beam stiffeners 11 arranged on the main beam 1 are prefabricated into a small whole; since the main beam stiffeners 11 are spliced by several s...

The invention discloses a split piece prefabrication process for connecting rod pieces with bolts. The process comprises the following steps: (1) reinforcing rib plates are mounted on the wing edges of main beams; (2) multiple main beam reinforcing rib plates are prefabricated as a small whole; (3) multiple main beam reinforcing rib plates are mounted on the main beams, and the prefabrication of the main beams is finished; (4) the main beams and secondary beams are assembled as horizontal layers; (5) the horizontal layers are leveled and placed on cushion piers; (6) the reinforcing rib platesare mounted on stand columns on two sides; (7) the reinforcing rib plates are fixed on the stand columns; (8) the stand columns on two sides and temporary inclined supports are mounted; (9) horizontalsupports are mounted among the stand columns for corrosion resistance; (10) fences are mounted; and the contacted surfaces of the horizontal supports are wrapped; (11) split pieces are subjected to corrosion-resistant treatment; and (12) the temporary inclined supports are supported between the main beams and the stand columns to finish prefabrication of the split pieces. The method solves the problem about prefabrication mounting precision of the connecting rod pieces with the bolts, greatly improves the prefabricating efficiency of deck pieces, and reduces the mounting 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...
