Description

The present invention relates to the construction of boats, yachts, and small-class ships made of a thin plate material, iron, stainless steel, aluminum, or the like that can be recycled and welded without causing pollution.

Although it is a high level in conventional ship building technology, the main materials used in actual ship building are mainly iron, wood, FRP (reinforced plastic), etc. A wooden ship connects wood board and wood board and pushes the cedar and cocoon skin softly, and puts putty, glue, etc. on the seam. FRP (reinforced plastic) ship forms a veneer board, etc. and attaches FRP (reinforced plastic) on it. Finish by painting. I've looked at some other literature, but it's technically high, but it's not taken into account at all, just building large ships and pollution ships.

Patent Document 1 is a reference to FRP (reinforced plastic) shipbuilding and pollution issues.
Regarding Patent Document 2, it is a matter of pollution if background technology (conventional technology) is described.
The above-mentioned Non-Patent Documents 1 and 2 were helpful for background technology and actual technical meditation.

There is a problem in the construction of boats from yachts, small ships, steel ships, wooden ships, FRP (reinforced plastic) ships, steel boards joints, unevenness, distortion, etc. FRP (reinforced plastic) ships, such as engineers, have another pollution problem, abandoned ships at each port, and FRP (reinforced plastic) ships are one of the problems of industrial waste all over the world. But we are moving to solve the processing problems, but we will solve these problems below.

In order to solve the above-mentioned problems, the present invention is a pollution-free, recyclable and weldable material, such as iron, stainless steel, aluminum, etc., divided into strips, and the plate thickness is half that of the conventional plate. By making the weight lighter and folding the S-shaped part of the slab from the top of the strip by the thickness of the plate,

At the center, the ends that support and overlap with the upper and lower parts are welded to the back and front, and a reinforcing plate is attached to the end of the back plate and welded to the overlapping plates. Welded. The overlapping back plates are made with 50Φ holes at equal intervals, welded along the circle from the back side, and the joints are welded together with the ribs on the ribs. The mutual strength is also increased, and the weight reduction makes it possible to greatly reduce labor, injury, risk, etc. during work, and these problems are solved by building a powerful ship.

Dividing the plate material that can only be recycled by this method using materials such as iron, stainless steel, and aluminum that can be recycled and can be recycled without causing pollution, and reducing the plate thickness to 1/2 of the conventional thin plate thickness material The s-shaped part is bent by the thickness of the plate at the position of 1/3 from the top of the strip. Increased unevenness and distortion have been eliminated, joints between thin plates and R part are welded together on the ribs, and there is no problem and the material has been reduced in weight to improve work efficiency, injury and risk The construction of a ship with this construction method, which has further strengthened the strength of the ship by increasing the number of welds, has been effective.

The present invention constructs boats, yachts and small-class ships in the best form with thin steel plates. Originally, the construction of thin plate materials is a problem of joints, unevenness, distortion, etc. between thin plates. Although there are few people who are building boats at this time, this construction method is free from pollution, can be recycled, can be welded, the plate material is divided into strips, and the plate thickness is also normal 1 Reduced to 2mm thickness, burned and overlapped, rounded into the part, head and end welded to the back and front, overlapped part using round hole and welding hole By tightening and welding with nuts, there is no unevenness or distortion, the joints are welded together on the ribs, the strength of the entire ship is increased by increasing the number of welded parts, and the work is done by reducing the weight of the material The risk of injury at the time can be reduced, and a strong ship is made of thin steel plate.

The embodiment will be described with reference to the drawings. FIG. 1 is a general view of a ship manufactured by the method of the present invention. The breakdown is as shown in FIGS. 2, 3, 4, 5, 6, 8, 9 2, which is the main part of the present invention, the upper part and the lower part of the S-shaped part overlap each other by inserting an S-shaped bend into the part to be rubbed and overlapped. The construction method is implemented in FIG. Fig. 1 shows a cross section of the Daimaru and Fig. 3 shows the inside of the ship obliquely. Also see the hole for welding, the head of the round rod, and the reinforcing plate in Fig. 7.

In FIG. 4, along the line of the arrow mark B-1 of the strip B already incorporated, the arrow C-1 of the strip C of FIG. 3 to C-8 from the stern to the stern, align the arrow mark D-1 of the strip D in FIG. 6 with the arrow mark line C-2 of the strip in FIG. Install up to D-7 toward the stern. 7, regarding the joining method and construction method of the thin steel plate of the title of the invention, the shape is a temporary rib, as shown in FIG. 7, the ship side depth 3 m × length 6 m, ship bottom width 3 m × length 6 m. At the place where it is temporarily assembled to the main rib, the outer welded part and the inner welded part are finished and the respective steps are completed, and then combined with the built-in hull and welded.

It is a front view which shows implementation of the hull made with the construction method of this invention. It is sectional drawing which shows the part which put the S-shaped bending which is the main of the construction method of this invention, and the upper part and the lower part meet. FIG. 2 is a perspective view showing an example in which a large circle portion of FIG. 1 of a hull made by the method of the present invention is viewed from the inside. It is an assembly drawing of the hull which shows in an example that a ship is built by burning and overlapping, according to the method of the present invention. It is a component drawing of the band board to which the ship made by the construction method of the present invention is burnt and overlapped. It is a component drawing of the band board to which the ship made by the construction method of the present invention is burnt and overlapped. It is an assembly in which a ship constructed by the method of the present invention is tentatively assembled together with blocks. The one that is rounded into the overlapping part of the strip. Hole for 50Φ welding of overlapping strips.

Claims (3)

The present invention divides a thin plate material, such as iron, stainless steel, aluminum, etc., that can be recycled and welded, into a strip shape, and reduces the weight to a thin plate material that can be used for boats with a thickness of 0 or 4. From the light and strong boat, this S-shape has a big role in shipbuilding with thin plates. Yacht, small ship class and ship construction that can be made of sheet steel while changing plate thickness. The S-shape increases the strength of the ship as a whole. The S-shape receives the upper and lower parts at the center and supports them with three rods. Weld the overlapped end, attach a reinforcing plate to the end of the strip on the back side and weld it to the overlapping strip, place round rivets at equal intervals on the overlapping portion, weld the head to the back and front, and the inner plate to 50Φ holes are opened at equal intervals and welded to the outer plate along the circle from the inside of the holes. The R part has a lot of temporary ribs along the R, and the overlapping part uses a round hole or 50Φ hole and is tightly attached and temporarily tightened with bolts and nuts. The joint between the thin plates is on the rib. Weld together. By supporting and sticking with the three rods, unevenness and distortion do not occur, the temporary rib is joined to this rib, the ship construction with this method that hardens the strength of the ship by increasing the welded part is the method of the present invention is there.
