Description

Technical Field

[0001] The invention relates to the technical field of ship outfitting, and in particular to an angle steel corner joint of a flower steel plate platform frame. Background Art

[0002] In ship design, various equipment and complex piping systems are arranged above the bottom plate of the engine room, occupying a large amount of space in the bottom plate of the engine room. In order to facilitate the maintenance and passage of the equipment on the bottom plate of the engine room, a platform frame is usually designed above the inner bottom plate in the design of the passage on the bottom plate of the engine room, which is used to lay a layer of 4.5-5mm thick steel plate channel platform to hide the complex piping system and some equipment under the platform. The steel plate of the platform is usually installed in the later construction process, so it is divided into several pieces during the design, and the weight of each piece is controlled within the range that can be operated manually (usually not more than 30kg). In order to prevent the steel plate from deforming due to load-bearing during use, the platform frame needs to support each side of each steel plate, and at the same time, it must meet the requirements of the countersunk screw fasteners for installing the steel plate.

[0003] In the process of modern shipbuilding's rapid technological advancement, there are more requirements for the aesthetics of ship design, such as requiring the seams of the decorative steel plates to be straight and continuous. Figures 1 to 4 As shown, there are four common structures of the flower plate platform frame, all of which are composed of multiple angle steels (1a and 1b) stacked together. The solid line in the angle steel 1a indicates that its folded edge is upward, and the dotted line in the angle steel 1b indicates that its folded edge is downward. When the flower plate is connected to the flower plate platform frame through countersunk screws, the number 1c in the figure is the position of the countersunk screw hole. However, the up and down directions of the angle steel folded edges at the edge corners are inconsistent, which is a contradiction in the beautification design process of the flower plate, as follows:

[0004] (1) The first structure: Figure 1 As shown in the figure, the distance between the flower plate and the upward folding edge of the angle steel is uniformly 15 mm. Some of the countersunk screw holes in the flower plate interfere with the downward folding edge of the angle steel and cannot be drilled; (2) The second structure: Figure 2 As shown in the figure, in order to ensure that the countersunk punching position of the flower plate does not interfere with each other and the plate seams are neat and consistent, the distance between the flower plate and the upward folding edge of the angle steel is too large, exceeding half of the width of the angle steel. After painting, the color is inconsistent, affecting the appearance; (3) The third structure: Figure 3 As shown, it ensures that the countersunk screw hole opening position does not interfere with each other, and the distance between the flower plate and the angle steel is 15mm, but the consistency of the flower plate seam is sacrificed (i.e., misalignment), and the finished flower plate is not rectangular, which is troublesome whether it is prefabricated or cut on site; (4) The fourth structure: Figure 4 As shown, this node is the currently used method to avoid the above problems, but it is necessary to cut several irregular angle steels when making the flower steel plate platform frame, and the construction process becomes extremely cumbersome. Summary of the invention

[0005] The purpose of the present invention is to provide a simple, compact and light angle steel corner joint for a flower steel plate platform frame, which is adapted to the fourth structural node of the existing flower steel plate platform frame.

[0038] The welding structure of the corner joint and the angle steel with the folded edge upward or folded edge downward is as follows:

[0039] (1) Figure 7 As shown, the angle steel corner joint of the flower steel plate platform frame of the present invention also includes a first external angle steel 5 and a second external angle steel 6; the first external angle steel 5 includes a first receiving plate 51 and a first folding plate 52 that are vertically connected to each other, and the side of the first receiving plate 51 is welded to the side of the right angle of the first external right angle 12 close to the inner right angle 11, and the side of the first folding plate 52 is correspondingly welded to one side of the corner plate 2 protruding from the top panel 1; the second external angle steel 6 includes a second receiving plate 61 and a second folding plate 62 that are vertically connected to each other, and the side of the second receiving plate 61 is welded to the side of the right angle of the second external right angle 13 close to the inner right angle 11, and the side of the second folding plate 62 is correspondingly welded to the other side of the corner plate 2 protruding from the top panel 1.

[0040] (2) Figure 8As shown, the angle steel corner joint of the flower steel plate platform frame of the present invention also includes a third external angle steel 7 and a fourth external angle steel 8; the third external angle steel 7 includes a third receiving plate 71 and a third folding plate 72 which are vertically connected to each other, the side of the third receiving plate 71 is welded to the side of the right angle of the first external right angle 12 away from the inner right angle 11, and the side of the third folding plate 72 is welded to the side of the first side panel 3 away from the corner plate 2; the fourth external angle steel 8 includes a fourth receiving plate 81 and a fourth folding plate 82 which are vertically connected to each other, the side of the fourth receiving plate 81 is welded to the side of the right angle of the second external right angle 13 away from the inner right angle 11, and the side of the fourth folding plate 82 is welded to the side of the second side panel 4 away from the corner plate 2.

[0041] (3) Fig. 9 As shown, the angle steel corner joint of the platform frame of the flower plate of the present invention can be welded to the first external angle steel 5, the second external angle steel 6, the third external angle steel 7 and the fourth external angle steel 8 respectively. When the flower plate is installed on the top panel 1, the first receiving plate 51, the second receiving plate 61, the third receiving plate 71 and the fourth receiving plate 81 by countersunk screws, the distance between the edge of the flower plate and the first folding plate 52 and the second folding plate 62 is 15mm.

It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
