Description

Technical Field

[0001] This invention relates to the field of marine oil engineering construction technology, and in particular to a device and process for a vertical H-beam and pipe assembly for a deck plate. Background Technology

[0002] Generally, the vertical beams and pipes of the deck panels need to be installed by crane. After they are assembled and in place, the next set can be installed. This not only takes up crane time, but also prevents the beams from being installed at the same time, which prolongs the prefabrication period of the deck panels and reduces the turnover rate of the workshop.

[0003] As my country's offshore oil development continues to advance into deep water, the weight of jackets and modules is increasing, as is the weight of workshop sections. The weight of the combined beams and pipes to be installed is also increasing, which makes installation more difficult. Each assembly requires a crane to lift it. Due to the limited number of cranes in the workshop, it is not possible to install the vertical beams simultaneously, which greatly increases the prefabrication cycle of deck sections and the cost of using the cranes. At the same time, it also requires occupying the site for a long time. Summary of the Invention

[0004] The main technical problem to be solved by this invention is the long prefabrication cycle of deck panels, the high cost of using cranes, and the long time occupied by the site. In order to overcome the above-mentioned defects of the prior art, an apparatus and process for vertical H-beams and pipe assemblies of deck panels are provided.

[0005] The technical solution adopted by this invention to solve its technical problem is: A device for vertical H-beams and pipe assemblies of deck plates, comprising a pipe fixing assembly for vertically fixing a first riser to a horizontal pipe; a clamp assembly for vertically fixing a vertical beam to a horizontal main beam; and a composite beam clamp assembly for vertically fixing a second riser to a horizontal main beam.

[0006] Furthermore, the tubular fixing assembly includes a first tubular clamp and a second tubular clamp. The first and second tubular clamps pass through the horizontal pipe and are sleeved on the horizontal pipe. The first vertical pipe is vertically fixed to the horizontal pipe by the first and second tubular clamps. The installation positions of the first and second tubular clamps are tightened by bolts. Furthermore, the horizontal pipe and the first vertical pipe are fixed by spot welding.

[0007] Furthermore, the clamp assembly includes a first combined beam clamp and a second combined beam clamp. The first combined beam clamp and the second combined beam clamp are installed on the horizontal main beam, and the vertical beam is vertically fixed on the horizontal main beam through the first combined beam clamp and the second combined beam clamp. The installation positions of the first combined beam clamp and the second combined beam clamp are tightened by bolts.

[0008] Furthermore, the vertical beam and the horizontal main beam are fixed together by spot welding.

[0009] Furthermore, the composite beam clamp assembly includes a third composite beam clamp and a fourth composite beam clamp. The third composite beam clamp and the fourth composite beam clamp are installed on the horizontal main beam. The second riser is vertically fixed on the horizontal main beam through the third composite beam clamp and the fourth composite beam clamp. The installation positions of the third composite beam clamp and the fourth composite beam clamp are tightened by bolts.

[0010] Furthermore, the second riser is fixed to the horizontal main beam by spot welding.

[0011] This invention also discloses a process for using a vertical H-beam and pipe assembly device for deck plates, which includes the following steps: Step 1: First, place the horizontal main beam, auxiliary beam, and horizontal pipe onto temporary piers, and add temporary supports underneath; after leveling, assemble and weld them together. Step 2: Install the first riser. Pass the first and second pipe clamps through the horizontal pipe and install them in place. Hoist the first riser and connect it with the horizontal pipe. Step 3: Adjust the verticality of the first riser. After adjustment, tighten the first and second pipe clamps with bolts. Then spot weld the horizontal pipe to the first riser. Remove the first and second pipe clamps for use in the installation of risers in other locations. Step 4: Install the first and second composite beam clamps onto the horizontal main beam; Step 5: The vertical beam is hoisted and installed vertically together with the horizontal main beam, and then fixed with the first and second combined beam clamps to prevent the vertical beam from tilting. Step 6: After ensuring the vertical beam is perpendicular to the horizontal main beam, tighten the clamps of the first and second combined beams with bolts; Step 7: Spot weld the vertical beam to the horizontal main beam, remove the clamps of the first and second combined beams, and complete the assembly of the vertical beam and the horizontal main beam; Step 8: Install the third and fourth composite beam clamps onto the horizontal main beam, hoist the second vertical pipe and install it vertically together with the horizontal main beam, and then use the third and fourth composite beam clamps to fix it to prevent the second vertical pipe from tilting. Step 9: After the second vertical pipe is perpendicular to the horizontal main beam, tighten the clamps of the third and fourth combined beams with bolts, spot weld the second vertical pipe to the horizontal main beam, remove the clamps of the third and fourth combined beams, and complete the assembly of the second vertical pipe and the horizontal beam.

[0012] The beneficial effects of this invention are: This invention, by setting up tubular fixing components, clamp components, and combined beam clamp components, can quickly install beams or pipe segments onto horizontal structures. After spot welding fixation, the hooks can be removed for installation in other positions, saving hoisting time and improving installation efficiency. By using this assembly device, the verticality requirement of beam assembly is guaranteed, saving crane usage costs and reducing production costs. Moreover, the assembly is simpler, more convenient, and safer.

[0013] Because of the above-mentioned device and process, the present invention has a simple structure and is easy to install. It not only greatly reduces the crane hoisting time for beams and pipes, but also has high installation accuracy, improves installation quality, saves installation time, greatly reduces production costs, improves production efficiency, and reduces the time spent occupying the site.

Further, after spot welding the vertical beam 2.2 to the horizontal main beam 6, the first combined beam clamp 2.1 and the second combined beam clamp 2.3 are removed, completing the assembly of the vertical beam 2.2 and the horizontal beam 6.

Step 4: Install the first composite beam clamp 2.1 and the second composite beam clamp 2.3 onto the horizontal main beam 6; Step 5: Hoist the vertical beam 2.2 onto the horizontal main beam 6, and then use the combined clamp 2.1 and combined beam clamp 2.3 to fix it to prevent the vertical beam 2.2 from tilting; Step 6: After the vertical beam 2.2 is perpendicular to the horizontal main beam 6, tighten the combined clamp 2.1 and the combined beam clamp 2.3 with bolts; Step 7: Spot weld the vertical beam 2.2 to the horizontal main beam 6, remove the clamps 2.1 and 2.3 of the composite beam, and complete the assembly of the vertical beam 2.2 and the horizontal beam 6; Step 8: Install the third composite beam clamp 3.1 and the fourth composite beam clamp 3.3 onto the horizontal main beam 6; Step 9: Hoist the riser 3.2 onto the horizontal main beam 6, and then fix it with clamps 3.1 and composite beam clamps 3.3 to prevent the riser 3.2 from tilting; Step 10: After the riser 3.2 is perpendicular to the horizontal main beam 6, tighten the clamps 3.1 and 3.3 of the composite beam with bolts; Step 11: Spot weld the riser 3.2 to the horizontal main beam 6, remove the clamps 3.1 and 3.3 of the composite beam, and complete the assembly of the riser 3.2 and the horizontal beam 6.
