Description

[Detailed description of the invention] This invention is a support structure for a lightweight deck, more specifically, a deck support structure that is installed at opposite ends of the deck of a ship that specializes in transporting light objects, such as a car carrier or a sheep carrier. Concerning structures supported by vertical members.

Generally, the deck is strongly supported by the deck transformer fixed to the deck, which is fixed to the side transformer and deck girder with brackets, but welding work is difficult and dangerous because there are many welding points and the footing is unstable. ing.

Furthermore, since the load applied to the deck of a car carrier or the like is very small compared to other decks, it does not necessarily need to be supported as firmly as described above.

The purpose of this invention is to provide a support structure for a lightweight deck that has a small number of welding points, is easy to weld, and has sufficient strength.

The lightweight deck support structure devised by this invention consists of a plurality of brackets fixed at right angles at predetermined intervals in the vertical direction to the lower surface of the horizontal deck support vertical members installed at mutually opposing positions. A slit formed in the vertical member at least at the bracket fixing position and an inverted T-shaped notch opened in the slit formed in the bracket are fixed to both ends of the deck in a downwardly protruding manner, and a face is fixed to the lower surface of the corresponding notch position. The stiffeners are inserted with a gap between them, and both ends of the deck are placed in direct contact with the upper surface of the deck support longitudinal member.

According to this invention, since both ends of the deck are not fixed to the deck support vertical members, there are fewer welding points and the welding work becomes easier.

Then, the stiffeners at both ends of the deck are inserted into the slits and notches of the deck support member and bracket with gaps, and both ends of the deck are placed in direct contact with the upper surface of the deck support longitudinal member. Therefore, even when the hull is vertically bent, no stress is generated on the deck, which prevents the relatively large vibrations of the deck itself from being transmitted to the hull, and the load is applied to the center of the deck. In some cases, both ends of the deck can be lifted so that large bending moments are not generated in the portion of the deck that contacts the inner edge of the deck support stringer.

Furthermore, since the face is fixed to the lower surface of the stiffener at the position corresponding to the notch, the deck does not fly up and is safe.

Embodiments of this invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view of a car carrier having a lightweight deck support structure according to this invention, in which both ends of a large number of decks 31 are fixed to the side shell plating 10 and the deck girder 21, respectively. 12 or Detsuki Girder-2
Deck support longitudinal members 12, 12 fixed to 1, 21, respectively
It is supported by a multi-layered deck.

FIGS. 2 and 3 show an embodiment in which both ends of the deck 31 are supported by deck supporting vertical members 12, 12 fixed to the ship side shell 10 and the deck girder 21, respectively.

Brackets 14 are fixed to side transformers 11 fixed to the outer panel 10 at predetermined intervals in the vertical direction.
, a horizontal deck support vertical member 12 is fixed to the side transformer 11 and the bracket 14.

Brackets 1 are also fixed to the deck girder 21 at predetermined intervals in the vertical direction.
4, a horizontal vertical member 12 is fixed.

A single slit 13 that continues in the longitudinal direction is formed in each of the deck support longitudinal members 12, and an inverted T-shaped notch 15 that opens at the position of the slit 13 is formed in each of the brackets 14.

A plurality of deck longitudinals 32 and deck transformers 33 are fixed to the lower surface of the deck 31.

Both ends of the deck transformer 33 are inclined, and the deck transformer 33 is provided to a position a predetermined length inside from both lateral ends of the deck 31.

That is, the deck transformer 33 is not provided at both lateral ends of the deck 31.

Stiffeners 34° 34 that are continuous in the vertical direction are fixed to the lower surfaces of both lateral ends of the deck 31, and the stiffeners 34 are inserted into the slits 13 and notches 15, so that the lower surfaces of both lateral ends of the deck 31 become vertical members. 12 and is supported in direct contact with it.

A face 35 is fixed to the lower surface of the stiffener 34 at the notch 15 position.

The slit 13 and the notch 15 are dimensioned to have a certain gap between them and the stiffener 34.

Although the slit 13 and the stiffener 34 are provided continuously in the vertical direction, they may be provided intermittently, for example, only at the bracket 14 position.

The case where both ends of the deck 31 are supported by the deck support vertical members 12, 12 fixed to the deck girders 21, 21, respectively, is similar to the above embodiment.

When vertical bending occurs in the hull, stress is generated in the deck support longitudinal member 12 based on this, but the slit 13 and the notch 15 are formed with a gap between them and the stiffener 34, and both ends of the deck 31 are Since the parts are only placed on the longitudinal members 12, no stress is generated in the deck 31 due to longitudinal bending of the hull.

Further, even if a relatively large vibration occurs in the deck 31 itself, this vibration will not be transmitted to the hull.

In addition, when a load is applied to the central part of the deck 31, both ends can be lifted, so that both ends of the deck 31
A large bending moment is not generated in the portion of the deck 31 that contacts the inner edge of the vertical member 12, unlike the case where the deck 31 is fixed to the vertical member 12.

Furthermore, the notch 15 of the stiffener 34 is formed by the face 35.
Since escape from the deck 31 is prevented, the deck 31 will not jump up from the longitudinal members 12.
