Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting method for mounting a traverse member to a longitudinal member previously mounted on a mounting surface in, for example, a ship or a bridge.

[0002]

2. Description of the Related Art Generally, a hull structure or the like has a reinforcing means composed of a longitudinal member (also called a long member) and a transverse member (also called a transformer member) mounted in a direction perpendicular to the longitudinal member. . As a method of attaching the traverse member to the longitudinal member, there is a method of attaching the traverse member to a longitudinal member previously installed at a predetermined place (so-called longitudinal member pre-attachment method).

As a specific example of such a mounting method, there is one as shown in FIGS. 8 and 9, which is a mounting surface 50a of a skin material (also referred to as a skin member) 50.
And a traverse member 52 having a plurality of T-shaped longitudinal members 51 each having a flange (also referred to as a face member) 51a at the end thereof and having T-shaped mounting grooves 53 formed side by side.
The mounting groove 53 is aligned with the end portion side of the longitudinal member 51.
The longitudinal member 51 is passed from the end side, the transverse member 52 is moved to a predetermined position X, and the transverse member 52 is welded to the longitudinal member 51.

Further, as shown in FIG. 10 and FIG.
An L-shaped attachment groove 53 having a width larger than that of the flange 51a of the longitudinal member 51 is formed in the transverse member 52, and the skin material 5 is formed.
No. 0 mounting surface 50a of the longitudinal member 51 that is mounted side by side in advance
The vertical member 51 is fitted into the mounting groove 53 from above and is lowered to be mounted at a predetermined position X, and the transverse member 52 is welded to the vertical member 51.

In this case, since the mounting groove 53 having a larger width than the flange 51a of the longitudinal member 51 is formed in the transverse member 52, the strength of the transverse member 52 is reduced. Therefore, as shown in FIG. 11, the web 51b of the longitudinal member 51 is
An auxiliary member (also called a color plate) 54 is attached between the cross member 52 and the traverse member 52 so as to maintain a certain strength.

[0006]

In the former mounting method described above, in the former case, if the mounting accuracy of the longitudinal member 51 is poor, the alignment between the longitudinal member 51 and the mounting groove 53 of the traverse member 52 will not be successful. First, the mounting groove 53 must be enlarged to accommodate the traverse member 5.
When the 2 is moved, the traverse member 52 may hit the longitudinal member 51, and the traverse member 52 may be deformed. In this case as well, the mounting groove 53 must be enlarged in the same manner as described above. If the mounting groove 53 is enlarged in this way, the gap between the longitudinal member 51 and the traverse member 52 becomes large, which makes it difficult to weld the longitudinal member 51 and the traverse member 52.

Further, in the latter mounting method, since the mounting groove 53 is formed large from the beginning, the traverse member 5
2 tends to be insufficient in strength, and as described above, the auxiliary member 5
4 must be mounted, and especially when a watertight structure is required, it is necessary to mount the auxiliary member 54 without fail, so that the number of parts and the amount of work increase.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for attaching a traverse member to a longitudinal member that can solve the above problems.

[0009]

[Means for Solving the Problems] The means for solving the problems in the present invention is a mounting for mounting a traverse member to a plurality of longitudinal members having a T-shaped cross section arranged side by side on a mounting surface of a structure. A method for removing a flange piece in a predetermined section of the longitudinal member to form a mounting portion for a traverse member, lowering the traverse member from above the mounting portion, and forming a T-shape on the lower side of the traverse member. The vertical groove portion below the mounting groove is fitted to the mounting portion, and then the flange piece previously removed from the longitudinal member is inserted into the horizontal groove portion above each mounting groove.

Further, there is provided a mounting method for mounting a transverse member on a plurality of longitudinal members having a T-shaped cross section which are arranged side by side on a mounting surface of a structure, wherein a flange piece in a predetermined section of the longitudinal member is attached. Removed and removed as the mounting part for the traverse member,
This flange piece is attached to the horizontal groove portion above the T-shaped mounting groove formed on the lower side of the traverse member, and then the traverse member is lowered from above the mounting portion to fit the vertical groove portion below the mounting groove into the mounting portion. It fits.

[0011]

In the above means for solving the problems, the flange piece in the predetermined section of the longitudinal member is removed to form a mounting portion for the transverse member,
The traverse member is lowered from above the mounting portion, the vertical groove portion below the T-shaped mounting groove formed on the lower side of the traverse member is fitted to the mounting portion, and then the flange pieces previously removed from the longitudinal members are Since it is inserted into the horizontal groove at the top of the mounting groove, it is not necessary to unnecessarily increase the width of the vertical groove, and therefore the strength required for the traverse member can be maintained and at the time of mounting the traverse member. Alignment can be done very easily.

Further, the flange piece in a predetermined section of the longitudinal member is removed to form a mounting portion for the traverse member, and this flange piece is mounted in the horizontal groove portion above the T-shaped mounting groove formed on the lower side of the traverse member, and thereafter. Since the traverse member is lowered from above the mounting portion and the vertical groove portion under the mounting groove is fitted into the mounting portion, the size of the horizontal groove portion can be minimized. The gap between the mounting groove and the mounting groove can be made extremely small, and the watertightness can be improved.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment of the present invention is an overall perspective view of FIG.
A description will be given based on the side views of FIGS. 2 and 3.

A structure 1 such as a ship is provided with a reinforcing means for a hull outer plate, which is a skin material 2.
It is composed of a plurality of longitudinal members 3 welded side by side on the mounting surface 2a of the (hull outer plate) and a traverse member 4 mounted in a direction perpendicular to the longitudinal members 3.

The longitudinal member 3 is formed in a T-shaped cross section from a web 5 to be welded to the skin material 2 and a flange 6 integrally formed at the upper end of the web 5. Further, the traverse member 4 is formed in a flat plate shape, and has a mounting groove 7 on the lower side thereof, and the mounting groove 7 includes a lower vertical groove portion 8 and
An upper elliptical horizontal groove portion 9 formed continuously with the vertical groove portion 8 and a substantially T-shaped portion are formed.

The mounting method for attaching the traverse member 4 to the longitudinal member 3 is as follows. In each longitudinal member 3, the flange piece 6a in a predetermined section is removed only at a necessary portion, and the flange piece 6a is removed. Is used as the mounting portion 11 of the traverse member 4, for example, the traverse member 4 is hung by the wire 12, and the vertical groove portion 8 of the mounting groove 7 is attached to the longitudinal member 3.
Position the mounting part 11 of.

Next, as shown in FIG. 2, the traverse member 4 is lowered to fit the mounting portion 11 into the vertical groove portion 8, and then, as shown in FIG.
As shown in FIG. 4, the flange piece 6a that has been removed in advance is inserted into the horizontal groove portion 9 of the mounting groove 7, and the transverse member 4 is welded to the attachment portion 11, whereby the transverse member 4 is attached to each longitudinal member 3. Perform such work in the necessary places.

Thus, according to the first embodiment of the present invention,
The flange piece 6a in a predetermined section is previously removed from the flange 6 of the longitudinal member 3 so that the web 5 having a width narrower than that of the flange 6 can be obtained.
Since the vertical groove portion 8 of the mounting groove 7 is aligned with the mounting portion 11 of the above, it is not necessary to unnecessarily increase the width of the vertical groove portion 8, and therefore, the transverse member 4 can retain the necessary strength and the transverse member. The alignment can be done very easily when mounting 4.

Further, even when the vertical groove portion 8 is fitted to the mounting portion 11, the gap between the vertical groove portion 8 and the mounting portion 11 can be reduced, and therefore, an auxiliary member such as a color plate is not required, and the longitudinal member is provided. 3 and the traverse member 4 can be easily welded, and the work time for mounting can be shortened.

Further, even when the traverse member 4 is mounted so as to be inclined with respect to the vertical plane, the traverse member 4 is lowered to fit the mounting portion 11 and the vertical groove portion 8 and then the traverse member 4 is placed on the spot. Since it is sufficient to incline, it is possible to improve the adaptability when mounting the traverse member 4.

Next, a second embodiment of the present invention will be described with reference to the whole perspective view of FIG. 4, the enlarged view of the essential portions of the traverse member of FIG. 5, and the side views of FIGS. 6 and 7. In the reinforcing means in the second embodiment of the present invention, the mounting groove 7 formed on the lower side of the transverse member 4 has a lower vertical groove portion 8 as shown in FIG.
It is formed in a T-shape from a rectangular horizontal groove portion 9 continuously formed on the upper portion of the vertical groove portion 8.

The structure of the other reinforcing means is the same as that of the first embodiment, and therefore its explanation is omitted. The mounting method for mounting the traverse member 4 having the mounting groove 7 as described above to the longitudinal member 3 first requires the flange piece 6a in a predetermined section in each longitudinal member 3, as in the first embodiment. Only the portion is removed, and the web 5 corresponding to the portion from which the flange piece 6a is removed is used as the mounting portion 11.

On the other hand, the flange piece 6a, which has been removed in advance, is attached to the horizontal groove portion 9, and then the traverse member 4 is hung by the wire 12, for example, and the vertical groove portion 8 of the attachment groove 7 is lengthened. Aligning with the mounting portion 11 of the through member 3, the traverse member 4 is lowered to fit the mounting portion 11 into the vertical groove portion 8 as shown in FIG. 6, and the flange piece 6a is flanged as shown in FIG. Welding to 6 and attaching part 1
The transverse member 4 is attached to each longitudinal member 3 by welding the transverse member 4 to 1.

According to the second embodiment of the present invention, since the horizontal groove portion 9 is formed in a rectangular shape and the transverse member 4 is attached to the horizontal groove portion 9 before attaching to the longitudinal member 3, the area of the horizontal groove portion 9 is reduced. Therefore, the gap between the horizontal groove portion 9 and the flange piece 6a can be made smaller than that in the first embodiment, which is particularly useful when the reinforcing means is required to be watertight.

[0025]

As is apparent from the above description, according to the present invention, the traverse member is lowered from above the mounting portion where the flange piece in the predetermined section of the longitudinal member is removed, and the T formed on the lower side of the traverse member. Since the vertical groove portion at the bottom of the V-shaped mounting groove is fitted to the mounting portion having a width narrower than that of the flange, it is not necessary to increase the width of the vertical groove portion. Therefore, it is possible to maintain the strength required for the traverse member. Alignment can be done very easily when mounting the traversing member.

Further, when the vertical groove portion is fitted to the mounting portion, the gap between the vertical groove portion and the mounting portion can be made small, and therefore, unlike the prior art, there is no need for an auxiliary member such as a color plate in the vertical direction. The passing member and the traversing member can be easily welded, and thus the working time for mounting can be shortened.

Further, by mounting the flange piece of the longitudinal member removed in advance in the horizontal groove before fitting the vertical groove into the mounting portion, the size of the horizontal groove can be minimized. The gap between the longitudinal member and the mounting groove can be made extremely small, and the watertightness can be improved.
