A kind of method of building hull panel
The present invention relates to a kind of method of construction of flat section of hull construction method, especially hull.
Because boats and ships bulky, hull can't monolithic construction, hull can only be divided into some builds, these pieces are called segmentation, divide intersegmental part floor to be arranged, structures such as stringers and pipeline, these structures need be welded and install, therefore need moulding bed and support segmentation in the manufacture process of segmentation, these moulding beds must can keep the profile of segmentation, thereby guarantee the precision of sectional construction.Flat section is in the past all built on the quincuncial pile moulding bed, the quincuncial pile dot matrix is arranged, promptly vertical on the ground, a horizontal or oblique perpendicular at regular intervals pile, these stakes are usually by the angle steel manufacturing, reticular density is generally 1 meter X1 rice, the angle steel height is generally between 0.8 meter to 1.2 meters so that the spot welding operation is as the criterion
When the base plate of flat section is positioned on the moulding bed operation, because area of thrust surface are little, slide easily between stake top and the base plate, spot welding between base plate and the stake must be fixed, cut off the point of connection of this segmentation and moulding bed after the sectional construction completion, and former point of connection position carried out repair welding and polishing, make the segmentation base plate not attractive in appearance, because the localized hyperthermia of repair welding influences, the microstructure of base plate is inhomogeneous simultaneously, the corrosion stability of hull reduces, simultaneously, destroyed the planeness on quincuncial pile top, before building next segmentation, must check the planeness of moulding bed, measure, again mark horizon, and the top mowing of stake can be gone up tire after smooth once more.Use this method of construction, there are a large amount of batches in segmentation of every construction, mend, the mill operation, need before each sectional construction to moulding bed measure, correction work, seriously hinder the raising of production efficiency, be unfavorable for improving the surface quality and the decay resistance of hull simultaneously.In addition, owing to need spot welding, moulding bed height must remain between 0.8 meter to 1.2 meters, this is highly higher, and production safety is affected.
Summary of the invention:
The purpose of this invention is to provide a kind of method of building the flat section hull, can significantly reduce body section and build repair welding and polishing work after finishing, make simultaneously and utilize moulding bed involved in the present invention to build also can to reduce greatly before the next segmentation work capacity that moulding bed is measured and proofreaied and correct.
The step of the method for construction flat section hull of the present invention is:
(1) channel-section steel or I-beam section are arranged by grid fix on the ground, the planar section and the ground of an end of I-beam section or channel-section steel are fixed, and adjust described I-beam section or channel-section steel, make its opposite side plane at grade;
(2) the interior baseplane lamellar body of hull is positioned on the last plane of the moulding bed that channel-section steel or I-beam section constitute;
(3) be fixed on the moulding bed of channel-section steel or I-beam section formation with the edge of anchor clamps baseplane lamellar body in described;
(4) stringers, floor assembly are lifted on described interior baseplane lamellar body, and lifting outer bottom lamellar body behind the prepackage pipe fitting, and other structures are installed, after all structures welding were fixed, installation was stood up and is hung sign indicating number, with molded sectional turn-over, and welds other parts.
Because the present invention has replaced quincuncial pile with the I-beam section of grid layout or the moulding bed of channel-section steel formation, area of thrust surface increase, and between lamellar body edge, interior baseplane and the moulding bed by clamp, be not easy between moulding bed and the sectional plan to slide, do not need the bottom surface lamellar body is welded on the moulding bed, only need the lamellar body edge, bottom surface and the moulding bed of segmentation are fixed, can effectively segmentation bottom surface lamellar body be positioned on the moulding bed, there is no any attachment point in lamellar body centre, bottom surface, need not weld, can significantly reduce repair welding and polishing work after sectional construction is finished, guarantee the degree of finish of hull surface, avoid reducing the decay resistance of hull owing to the high temperature action of welding., can directly take off after the segmentation completion simultaneously, need not cut, moulding bed itself is not caused damage, build and also can reduce work capacity that moulding bed is measured and proofreaied and correct before the next segmentation greatly owing to there is not weld nugget.In addition, owing to do not need spot welding, the height of moulding bed can reduce greatly, and production safety is more secure.

The specific embodiment:
The step of the method for construction flat section hull involved in the present invention is:
(1). channel-section steel or I-beam section 1 arranged by grid to fix on the ground, and the planar section 2 and the ground of an end of I-beam section or channel-section steel 1 are fixed, and adjust described I-beam section or channel-section steel, make opposite side plane 3 at grade;
The planar section 2 and the described I-beam section of ground fixed form of one end of described I-beam section or channel-section steel 1 maybe can be that the one transverse plane is embedded in below ground, or riveted joint on the ground, the mode that adopts in this enforcement as shown in Figure 3, with bolt, nut 8 channel-section steel or I-beam section and ground are fixed, be convenient to the adjusting level.Bolt, nut fix I-beam section or channel-section steel on the ground by tightening up pressing plate, and pressing plate one end is pressed on the bottom side of channel-section steel or I-beam section, and an end and ground are fixed.This mode helps at any time the moulding bed planeness being adjusted more.
The grid of the channel-section steel density of arranging can be: longitudinal pitch 2-2.5 rice, and transverse pitch 4-5 rice, owing to adopted the moulding bed of continuous grids, area of thrust surface increase, and can reduce mesh-density, simplify the adjusting work of moulding bed, increase work efficiency.
(2). the interior baseplane lamellar body 4 of hull is positioned on the last plane of the moulding bed that channel-section steel or I-beam section 1 constitute;
(3). be fixed on the moulding bed of channel-section steel or I-beam section 1 formation with the edge 5 of anchor clamps baseplane lamellar body 4 in described;
Described anchor clamps can be that bolt, nut are fixed, or other general-duty plate jockeies, and the fixed form that present embodiment adopts adopts webge clip that body section bottom edge and I-beam section are fixed together as shown in Figure 4.Adopt this mode fixed hull segmentation bottom edge need not weld, install and take off all very convenient, and can not cause damage, further reduce the patch work amount of body section and the adjusting work amount of moulding bed body section and moulding bed.
(4). stringers, floor assembly 6 are lifted on the described interior baseplane lamellar body 4, and lifting outer bottom plane lamellar body 7 behind the prepackage pipe fitting, and other structures are installed, with the welding of all structures fixing after, installation is stood up and is hung sign indicating number, with molded sectional turn-over, and welds other parts.
Facts have proved, adopt the present invention to build hull, under the situation of identical personnel, equipment and other working conditions, can bring up to 1400 tons with monthly output from using 800 tons of orthodox method, output improves nearly one times.
