Thereby, even when the reinforcement member of the deck crane is installed in order to reinforce a base part 21 from below under a base potion 21 having a square shape in a plane view of the deck crane 20, a narrow part is hardly formed among the reinforcement member of the deck crane, the deck cross beams 14 and the longitudinal stiffeners 15.SELECTED DRAWING: Figure 3

Description

本発明は、船舶に設けられて港湾等の荷役作業をつかさどるデッキクレーンに関し、デッキクレーンの設置構造及びこの構造を備える船舶に関する。   The present invention relates to a deck crane that is provided on a ship and handles a cargo handling operation such as a harbor, and more particularly to an installation structure of a deck crane and a ship having this structure.

船舶に設けられるデッキクレーンとして、特許文献１には、船舶の上甲板上に立設された円筒形状のクレーンポストを備えるものが記載されている。このようなデッキクレーンを上甲板上に設置する場合には、一般的に、デッキクレーンが転倒モーメント、吊荷荷重、自重等に耐え得るようにするため、上甲板に対するデッキクレーンの補強が必要である。このような補強として、上甲板に対してデッキクレーンを下方から補強するデッキクレーン補強部材が、上甲板の下面側に例えば溶接によって設けられる。   As a deck crane provided in a ship, Patent Document 1 describes a cylinder crane provided with a cylindrical crane post erected on the upper deck of a ship. When such a deck crane is installed on the upper deck, it is generally necessary to reinforce the deck crane against the upper deck so that the deck crane can withstand a tipping moment, a suspended load, its own weight, etc. is there. As such reinforcement, a deck crane reinforcing member for reinforcing the deck crane from below with respect to the upper deck is provided on the lower surface side of the upper deck, for example, by welding.

特開２０１４−９４８２１号公報JP 2014-94821 A

ところで、上甲板は、一般的に複数の上甲板補強部材によって下方から補強されている。上甲板補強部材は、船舶の左右方向に沿って延在する複数の部材と、船舶の前後方向に沿って延在する複数の部材と、によって格子状に構成されている。   By the way, the upper deck is generally reinforced from below by a plurality of upper deck reinforcing members. The upper deck reinforcing member is configured in a lattice shape by a plurality of members extending along the left-right direction of the ship and a plurality of members extending along the front-rear direction of the ship.

このため、デッキクレーンを上甲板上に設置する場合には、上甲板の下面側に格子状に配置された上甲板補強部材を避けて、デッキクレーン補強部材を設ける必要がある。しかしながら、クレーンポストは円筒形状であるためデッキクレーン補強部材も円形状に形成すべき一方で、上甲板補強部材は格子状に構成されている。このため、デッキクレーン補強部材と上甲板補強部材との間には多数の狭隘部が形成されてしまう。このような狭隘部においては、例えばデッキクレーン補強部材を上甲板の下面側に溶接によって設けなければならず、デッキクレーンの補強の作業性が著しく悪化する。   For this reason, when installing a deck crane on an upper deck, it is necessary to avoid the upper deck reinforcement member arrange | positioned at the lower surface side of the upper deck at the grid | lattice form, and to provide a deck crane reinforcement member. However, since the crane post is cylindrical, the deck crane reinforcing member should be formed in a circular shape, while the upper deck reinforcing member is configured in a lattice shape. For this reason, many narrow parts will be formed between the deck crane reinforcing member and the upper deck reinforcing member. In such a narrow part, for example, a deck crane reinforcing member must be provided on the lower surface side of the upper deck by welding, and the workability of reinforcing the deck crane is significantly deteriorated.

そこで、本発明は、上甲板に対する補強の作業性を向上させることができるデッキクレーンの設置構造及びその構造を備える船舶を提供することを目的とする。   Then, an object of this invention is to provide the ship provided with the installation structure of the deck crane which can improve the workability | operativity of reinforcement with respect to an upper deck, and the structure.

本発明に係るデッキクレーンの設置構造は、船舶の上甲板上に設けられた土台部と、土台部上に立設されたクレーンポストと、を備え、土台部の下端の外縁部は、平面視において四角形状を呈する。   A deck crane installation structure according to the present invention includes a base portion provided on an upper deck of a ship, and a crane post erected on the base portion, and an outer edge portion at a lower end of the base portion is seen in a plan view. In FIG.

このデッキクレーンの設置構造では、船舶の上甲板とクレーンポストとの間に土台部が設けられている。そして、土台部の下端の外縁部は、平面視において四角形状を呈する。このため、デッキクレーンの土台部下に当該土台部を下方から補強するためのデッキクレーン補強部材を設けた場合であっても、当該デッキクレーン補強部材と、一般的に上甲板の下面側に格子状に配置されて上甲板を下方から補強する上甲板補強部材と、の間に狭隘部が形成されにくい。よって、上甲板に対する補強の作業性を向上させることが可能となる。   In this deck crane installation structure, a base portion is provided between the upper deck of the ship and the crane post. And the outer edge part of the lower end of a base part exhibits square shape in planar view. For this reason, even when a deck crane reinforcing member for reinforcing the base portion from below is provided below the base portion of the deck crane, the deck crane reinforcing member and a lattice pattern are generally formed on the lower surface side of the upper deck. It is difficult to form a narrow portion between the upper deck reinforcing member and the upper deck reinforcing member that is disposed on the upper deck and reinforces the upper deck from below. Therefore, it is possible to improve the workability of reinforcement for the upper deck.

ここで、土台部は、直方体状を呈していてもよい。これによれば、土台部の形状を単純化することで、土台部を容易に形成することができる。   Here, the base portion may have a rectangular parallelepiped shape. According to this, the base part can be easily formed by simplifying the shape of the base part.

また、船舶としては、具体的には、当該船舶の左右方向に沿って延在し、上甲板を下方から補強する複数の第１上甲板補強部材と、当該船舶の前後方向に沿って延在し、上甲板を下方から補強する複数の第２上甲板補強部材と、を備える構成が挙げられる。これによれば、デッキクレーンの土台部下に当該土台部を下方から補強するためのデッキクレーン補強部材を設けた場合であっても、当該デッキクレーン補強部材と、第１上甲板補強部材及び第２上甲板補強部材と、の間に狭隘部が形成されにくい。   Moreover, as a ship, specifically, it extends along the left-right direction of the said ship, and several 1st upper deck reinforcement members which reinforce an upper deck from the downward direction, and it extends along the front-back direction of the said ship. And the structure provided with the some 2nd upper deck reinforcement member which reinforces an upper deck from the downward direction is mentioned. According to this, even when the deck crane reinforcing member for reinforcing the base portion from below is provided below the base portion of the deck crane, the deck crane reinforcing member, the first upper deck reinforcing member, and the second It is difficult to form a narrow portion between the upper deck reinforcing member and the upper deck reinforcing member.

また、第１上甲板補強部材としては、具体的には、上甲板における横式の主要支持部材である甲板横桁であり、第２上甲板補強部材としては、具体的には、複数の甲板横桁に固定された縦通防撓材である構成が挙げられる。これによれば、デッキクレーン補強部材を設けた場合であっても、当該デッキクレーン補強部材と、甲板横桁及び縦通防撓材と、の間に狭隘部が形成されにくい。   In addition, the first upper deck reinforcing member is specifically a deck girder that is a horizontal main support member in the upper deck, and specifically, the second upper deck reinforcing member is a plurality of decks. The structure which is the longitudinal stiffener fixed to the cross beam is mentioned. According to this, even if it is a case where a deck crane reinforcement member is provided, a narrow part is hard to be formed between the said deck crane reinforcement member, a deck cross beam, and a longitudinal stiffener.

また、外縁部の各辺は、第１上甲板補強部材又は第２上甲板補強部材の直上にそれぞれ位置していてもよい。これによれば、デッキクレーンの転倒モーメント、吊荷荷重、デッキクレーンの自重等が、デッキクレーンから第１上甲板補強部材及び第２上甲板補強部材に確実に伝達される。このため、上甲板の下面側において、上甲板に対してデッキクレーンを下方から補強するデッキクレーン補強部材が不要になる。   Further, each side of the outer edge portion may be located immediately above the first upper deck reinforcing member or the second upper deck reinforcing member. According to this, the falling moment of the deck crane, the suspended load, the weight of the deck crane, and the like are reliably transmitted from the deck crane to the first upper deck reinforcing member and the second upper deck reinforcing member. For this reason, on the lower surface side of the upper deck, a deck crane reinforcing member for reinforcing the deck crane from below with respect to the upper deck becomes unnecessary.

また、土台部は、当該土台部の少なくとも内部に形成されており、当該土台部を補強する土台部補強部材を備えていてもよい。これによれば、土台部を補強することができると共に、土台部補強部材を備えた土台部を予め形成しておき、この土台部を上甲板上に設置すればよく、作業性を向上させることができる。   Moreover, the base part is formed at least inside the base part, and may include a base part reinforcing member that reinforces the base part. According to this, it is possible to reinforce the foundation part, and to form the foundation part provided with the foundation part reinforcement member in advance, and to install this foundation part on the upper deck, thereby improving workability. Can do.

また、土台部補強部材は、上甲板とは離間した位置に形成されていてもよい。これによれば、土台部補強部材を備えた土台部を予め形成しておき、この土台部を上甲板上に設置すればよく、作業性を向上させることができる。   Further, the base portion reinforcing member may be formed at a position separated from the upper deck. According to this, the base part provided with the base part reinforcement member should be formed beforehand, and this base part should just be installed on an upper deck, and workability | operativity can be improved.

また、本発明は、上述したいずれかのデッキクレーンの設置構造を備える船舶として捉えることもできる。この船舶では、デッキクレーンの設置構造と同様に、上述した作用及び効果を奏することが可能となる。   Moreover, this invention can also be grasped | ascertained as a ship provided with the installation structure of one of the deck cranes mentioned above. In this ship, it is possible to achieve the above-described functions and effects as with the deck crane installation structure.

本発明によれば、デッキクレーンを設置するに際して、狭隘部が形成されにくく、上甲板に対する補強の作業性を向上させることが可能となる。また、位置取りによっては、補強部材が不要となり、更に、予め土台部を形成しておくことが可能なので作業性を向上させることができる。   According to the present invention, when installing a deck crane, it is difficult to form a narrow portion, and it is possible to improve the workability of reinforcing the upper deck. Further, depending on the positioning, a reinforcing member is not required, and furthermore, a base portion can be formed in advance, so that workability can be improved.
