The elevating bar 100 capable of vertically correcting and supporting a connection according to an embodiment of the present invention is stably installed on the deck sheathing 13 of the offshore structure 10 by connecting and supporting corresponding to the degree of protrusion of the upper structure 11 The vertical height with the deck 12 can be corrected so that the operator can smoothly move between the upper structure 11 and the deck 12 to perform a predetermined operation.

The elevator base 100 capable of vertically correcting and connecting the elevator according to the present embodiment includes a body portion, an auxiliary step portion 120, and a gap holding portion 130.

The body portion is a structure having a predetermined height and is divided into a multi-layered work space 110, so that an operator can easily move to another space through interlayer movement. .

The body portion may be a structure installed by being installed with an H beam or the like, and may have a structure in which a plurality of work spaces are arranged in a row in a vertical direction.

One work space 110 includes a hexahedral support frame 111 and a plate-shaped work platform 113 disposed under the support frame 111. The work platform 113 allows an operator to perform a predetermined work on the upper surface thereof or to move to a work space located on the other floor.

A plurality of work platforms 113 may be provided so as to have different heights so that work can be performed according to various heights. In the figure, the work platforms 113 have a four-layer structure.

The work platform 113 may further include a middle end 115. The middle end 115 allows movement between the plurality of work platforms. The middle end 115 may be formed in the work platform of the upper layer so as to be able to move up and down with the work platform of the lower layer

The safety guard part 117 is formed in a pipe shape and is vertically installed in the transverse direction between the support frames 111 to prevent an operator from falling down. A plurality of the safety rails 117 may be provided, and the safety rails 117 may be installed on the support frame 111 by welding or the like.

The uppermost work space 110 may be provided with a leg 140 connected to an upper portion of the upper structure 11. The legs 140 are installed between the upper work platform of the uppermost work space 110 and the upper part of the upper structure 11 so that the worker can smoothly move between the uppermost structure and the upper structure 11 of the platform 100 do.

The auxiliary step 120 may be provided on at least one of the work spaces of the body part.

The auxiliary step 120 is provided on the side of the supporting frame 111 constituting the working space and connects the working platform 113 of the working space and the deck 12 of the offshore structure 10, Allowing the platform 113 and the deck 12 to move up and down.

Referring to FIG. 3, one end of the auxiliary step 120 is hingedly connected to an auxiliary platform 119 extending from the work platform 113 toward the offshore structure 10.

The auxiliary stepped portion 120 is basically mounted in a state of rotating toward the platform 100 and the end of the handle can be fixed by the fixing portion 122 provided on the upper portion of the support frame 111 state 1). Here, the fixing part 122 can be easily fixed and separated, for example, by adopting a structure in which a handle is hooked.

The auxiliary stairs 120 are installed in a state inclined toward the platform 100 so as to minimize interference with the offshore structure 10 during installation of the platform 100, thereby facilitating installation.

When the fixed portion of the fixing portion 122 is released in order to align the step between the work platform 113 and the deck 12 after the platform 100 is installed, the platform 100 becomes rotatable about the hinge, So that the foot end of the step 120 can be pivoted to meet the deck 12.

The auxiliary step 120 can be stably fixed to the deck 12 by performing bolt welding at the point where the foot end of the auxiliary step 120 meets the deck 12, Even if the height of the work platform 113 and the height of the deck 12 are not matched to each other, the step difference can be solved due to the existence of the auxiliary step 120 (vertical correction state-state 2).

1, the gap maintaining part 130 is provided between the lowest work space and the deck sheathing 13 so as to be adjustable in length, and varies its length according to the degree of protrusion of the upper structure 11, 100 so that the platform 100 is held vertically and the work platform 113 is kept horizontal so that there is no inconvenience in work by the operator.

4 and 5, the gap maintaining part 130 includes a gap maintaining bar 210 in which a part of the body is accommodated in a receiving space 220 provided below the support frame 111. [ An opening 221 is formed in one side of the accommodation space 220 so that the inside and the outside can communicate with each other and the body of the space holding part 130 can be inserted through the opening 221.

One end of the gap maintaining bar 210 is exposed to the outside and can proceed toward the deck sheathing 13 while the other end is accommodated in the accommodating space 220 to keep the gap maintaining bar 210 horizontal.

The bearing space 222 is provided in the accommodation space 220 so that the gap maintaining bar 210 can slide smoothly

A plurality of fixing holes 212 are formed at regular intervals on the upper surface of the gap maintaining bar 210 and a plurality of gap adjusting holes 224 are formed on the upper surface of the accommodation space 220 at regular intervals. In this case, the interval between the plurality of fixing holes 212 and the interval between the plurality of interval adjusting holes 224 may be the same or in a proportional relationship.

The size and shape of the fixing hole 212 and the gap adjusting hole 224 may be the same or proportional to each other so that the fixing tip 226 is spaced apart from the gap adjusting hole 224 and the fixing hole 212 At the same time, it is possible to prevent the interval maintaining bar 210 from sliding arbitrarily.

The protruding length of the gap maintaining bar 210 can be determined by the fixing tip 226 and the protruding length can be extended or reduced in units corresponding to the interval of the interval adjusting holes 224 or the interval of the fixing holes 212 have.

According to another embodiment, when a plurality of fixing holes 212 are formed on the upper surface of the gap maintaining bar 210, only one gap adjusting hole 224 may be formed on the upper surface of the accommodation space 220. Or if a plurality of spacing holes 224 are formed on the upper surface of the receiving space, only one fixing hole 212 may be formed on the upper surface of the spacing bar 210.

A protection member 131 is provided at one end of the gap maintaining portion 130 to minimize the impact applied to the deck sheathing 13 to prevent the deck sheathing 13 from being damaged. The protective member 131 may be made of a material having a high frictional force (for example, rubber or the like). The shape of the protective member 131 may be frictional force in relation to the deck sheath 13, Various shapes may be applied.

A plurality of spacing members 130 are provided in the horizontal direction so that the connection of the platform 100 can be more stably supported.

Although FIGS. 1 and 2 illustrate that the interval maintaining unit 130 is provided only in the lowest work space, this is only an example and may be provided in the intermediate work space as required .

According to the present embodiment, the steps between the work platform 113 and the deck 12 of the platform 100 can be matched through the auxiliary step 120 to correct the vertical height, It is possible to stabilize and connect the platform 100 to the deck shell 13 of the offshore structure 10 by adjusting the protrusion length of the interval maintaining bar 210 according to the degree of protrusion.
