Currently, keel is generally used for a plate keel using a thick plate than a square keel using square bars or pipes, angles, beams, or bottom plates using steel bars.

The keel of this type is provided along the longitudinal direction in the center of the lower plate of the ship to support the entire frame of the ship, and then joined by welding along the longitudinal direction after the lower end of the vessel on both sides of the keel.

However, the conventional keel for ships was not easy to weld the side end of the lower plate to both sides of the keel of the aluminum material, in order to weld the lower plate to both sides of the keel, the corresponding ends of the lower plate to the sides of the keel close to the curvature of the bent keel close The work was very complicated because we had to weld the corresponding parts and welded the keel and the bottom plate. In fact, when the keel and the bottom plate were welded, the bottom plate was often not welded on both sides of the keel according to the design angle. It caused an accident.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a keel for ships so that the corresponding ends of the lower plate can be easily coupled to both sides of the keel.

Another object of the present invention is to provide a keel for ships so that the design angle between the keel and the lower plate is accurately maintained.

Still another object of the present invention is to provide a keel for ships so that the lower keel is not damaged even by an external impact.

Still another object of the present invention is to provide a keel for ships so that the lower plates are simply coupled to both sides of the keel and are not separated.

Still another object of the present invention is to provide a keel for ships, in which a concave groove is filled between both sides of the upper keel and the lower plate when the lower plates are coupled to the keel.

The keel for ship of the present invention for achieving the above object is provided with a keel upper portion long along the center of the lower plate of the vessel and supported on the upper surface of the lower plate; A lower plate support provided integrally with the lower portion of the upper keel and provided along the central portion of the lower plate of the ship and supported on the lower surface of the lower plate; Lower plate coupling grooves formed between the keel upper portion and the lower plate support portion and having corresponding ends of the two lower plates inserted therein so that the pair of lower plates are coupled to both sides of the keel; A keel lower portion provided integrally with the lower plate support portion and provided along the center portion of the lower plate of the ship and protecting the lower plate against external impacts; It is formed between the lower plate support and the lower keel, and when the lower keel collides with the outside, so that both sides of the lower keel elastically deformed is characterized by consisting of side elastic grooves to absorb the external impact.

Another feature of the vessel keel of the present invention, the pair of lower plate coupling grooves, is provided to achieve the same angle as the angle of the pair of lower plates provided on both sides of the keel.

Another feature of the vessel keel of the present invention, the side elastic grooves, the width of the inner groove portion is formed larger than the width of the entry groove portion so that the elasticity of both sides of the lower keel is increased.

Still another feature of the ship keel of the present invention, the central portion of the keel, the central elastic portion is formed so as to absorb the impact when an external impact is transmitted to the central portion of the lower keel.

Another feature of the vessel keel of the present invention, the upper groove finish band is extended on both sides of the keel upper portion to fill the concave groove portion generated between both sides of the keel upper portion and the upper surface of the lower plate.

In the present invention as described above, between the upper keel and the lower plate support, the lower side coupling grooves are formed such that the corresponding side ends of the two lower plates are inserted so that the pair of lower plates are coupled to both sides of the keel. Therefore, when the corresponding side ends of the two lower plates are opposed to the lower plate coupling grooves and then pushed into the lower plate coupling grooves, the lower plates are simply coupled to the keel. Therefore, the work of joining the lower plates to the keel is very simple and quick.

The vessel keel of the present invention has side elastic grooves formed between the lower plate support and the lower keel so that both sides of the lower keel elastically deform when the lower keel collides with the outside to absorb the external impact. Therefore, even if an external impact is applied while the keel of the ship hits a sandbar or a reef, the lower keel is elastically deformed by the side elastic grooves to absorb and offset the impact, thereby preventing the keel from being damaged from the external impact.

The pair of lower plate coupling grooves of the present invention are provided to form an angle equal to the angle formed by the pair of lower plates provided on both sides of the keel. Therefore, simply push the pair of lower plates into the lower plate coupling grooves on both sides of the keel to simply assemble the lower plate of the vessel according to the design angle, thereby manufacturing the vessel in an optimal state.

In the central portion of the lower keel of the present invention, a central elastic elastic groove is formed to absorb the impact when an external impact is transmitted to the central portion of the lower keel. Therefore, when the external impact acts perpendicular to the center of the lower keel, the elastic portion of the central portion is elastically deformed to absorb the impact, thereby protecting the keel from being damaged.

In the lower plate coupling grooves of the present invention, a packing is inserted to increase the frictional force with the inserted lower plate end and to maintain watertightness. Therefore, when the side end portion of the lower plate is pushed into the inside of the packing, as the side end portion of the lower plate is in close contact with the packing, the bonding force therebetween increases as well as the watertightness therebetween increases.

In addition, in the lower plate coupling grooves of the present invention, wedge grooves are formed to engage the wedge protrusions so that the wedge protrusions formed at the lower plate end portions do not escape after entering the inside of the lower plate coupling grooves. Therefore, if the wedge projections of the lower plate are pushed into the wedge grooves of the keel, both sides of the upper keel and the lower plate support portion elastically open, and the wedges of the lower plate enter the inner side of the wedge groove, and the lower plate is completely coupled to the lower plate coupling grooves of the keel. If the wedges are coupled to the wedge grooves are not separated. Therefore, simply push the bottom plate on both sides of the keel is simply combined, and once combined, it is not easy to remove the assembly work is very easy and the assembly state is solid.

On both sides of the keel upper portion of the present invention, the upper groove finishing band is extended to fill the concave groove portion generated between both sides of the keel upper portion and the upper surface of the lower plate. Therefore, when the lower plate is coupled to both sides of the keel, concave grooves are not generated between both sides of the upper surface of the keel and the upper surface of the lower plate, so that foreign matters are not caught therein.
