Embodiment
Below in conjunction with accompanying drawing, the present invention is described further, but the present invention is not limited by the following examples.
As shown in Figure 1, Figure 2 and Figure 3, in shipbuilding, T profile watertight mends the vacuum (-tight) housing of slab integral watertightness detection, comprises left cover body 1 and right cover body 2.Left cover body 1 comprises mainboard 10, sealing panel 11, inner seal web 13 and outer side seal web 14; Mainboard 10 can be semicircle or square, when for time square, outer side seal web 14 one end is connected to the outer ledge (upper and lower and left side) of mainboard 10, the other end connects sealing panel 11, below sealing panel 11, establish sealing bottom surface bar 12, this sealing bottom surface bar 12 is located at T profile watertight and mends on the hull of plate periphery simultaneously; Inner seal web 13 is located at mainboard 10 inside edge (right side), is provided with inner seal bar 6 outside inner seal web 13; Outside outer side seal web 14, be provided with outside seal strip 7, outside seal strip 7 is connected with inner seal bar 6; Inner seal web 13 is provided with the depression 8 of to mend plate with T profile watertight and matching; Mainboard 10 is provided with mainboard stiffener 4, can be 2 or many.Mainboard 10, sealing panel 11, inner seal web 13 and outer side seal web 14 all can adopt pmma material, and inner seal bar 6, outside seal strip 7, sealing bottom surface bar 12 can adopt soft rubber bar.
Right cover body 2 is identical with left cover body 1 structure, and symmetrically, during work, left cover body 1 and right cover body 2 are mended the left and right sides assembling close to each other of plate from T profile watertight, depression 8 just surrounds T profile, and be tightly connected by inner seal bar 6, left cover body 1 is provided with bleeding point and tensimeter 5, detection is vacuumized to cover body, under the effect of vacuum pressure, each sealing joint strip (inner seal bar 6, outside seal strip 7, sealing bottom surface bar 12) is closely pull-in in hull or T profile, forms the pre-close property detection space that T profile watertight mends plate.
In this shipbuilding, T profile watertight mends the vacuum (-tight) housing of slab integral watertightness detection, be made up of organic glass, soft rubber bar and tensimeter etc., on the watertight weld seam be verified, test liquid is sprayed during test, vacuum box is covered in welded joints, form negative pressure and reach setting, inspection weld seam whether seepage, thus complete the pre-tightness test work of weld seam.Vacuum (-tight) housing piece cover is mended on plate at T profile watertight, the close sex work of whole piece weld seam can be ensured, and the Method compare T profile watertight that entirety vacuumizes mends the mode that plate top one side of something vacuumizes, and has test effect strong, test integrality advantages of higher.
The vacuum (-tight) housing adopting T profile watertight in this shipbuilding to mend slab integral watertightness detection is mended slab integral watertightness to T profile watertight and is detected, meet the feature of process stages reach, it reduces the workload of dock (building berth) tightness test, shorten dock (building berth) cycle, optimize tightness test environment, high-altitude closed operation is become level land and opens wide operation, and test method is simple and reliable, quality is easy to control, and greatly increases work efficiency, and reduces tightness test cost.Directly sand washing, painting operation can be carried out to the weld seam successfully passing the inspection of pre-close property.The strong integrality that ensure that segmentation application, decreases the workload of dock (building berth) application coating.
