Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a press wall used as a partition wall for ships and the like.

[Conventional technology]

A press wall αQ as shown in FIG. 2 is widely used as a structural partition wall. That is, the press wall C1 (I is a thin steel plate formed by a press with a protruding convex part (to) and a flat concave part (7)).

[Problem that the invention seeks to solve]

As shown in Fig. 2, this press wall α1 is placed on a supporting material (50) as a partition wall. The load is applied to the floor surface (51) side on which the convex member rests, and the strength of that part becomes extremely weak.Also, if it is installed directly on the support material (50), the part that can be welded will not be supported. There is also the problem that only the concave part 4 on the material (50) becomes discontinuous and the joint strength of that part becomes weak. (1) makes welding time-consuming and increases the number of welding steps.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and improves the continuity of the joint surface between the longitudinal ends of the uneven length of the press wall and the structural member joined thereto, and does not require much effort during joining. The purpose is to provide a press wall.

[Means for solving problems]

Therefore, the present invention utilizes a press wall (
Flat portions (4) (411) are formed at both longitudinal ends of the uneven portions (2) and (3) of 1).

This flat part (4) (41L) is made into four parts (2) by squeezing the longitudinal end of the convex part (3) as shown in Fig. 4.
It was leveled and pressed flat. The space should be within the minimum necessary range (approximately 100% to 400%), and if it is provided within this range, there will be no problem in terms of strength since it is a narrow panel.

[For production]

When the press wall (1) uneven parts (2) (3) flat parts (4) provided at both longitudinal ends (4a) are joined to the structural member, it rests on it in a straight line, so the joined part is continuous. I will do it.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 5 (1) shows one embodiment of the present invention.
is used. This press wall (1) has uneven parts (2
1 (3) The flat parts (4) (4a) at both ends in the longitudinal direction are connected to the upper deck (62) and the upper end of the transverse bulkhead (6o), of which the upper end of the transverse bulkhead (60) (Fig. 5(b)) is connected. 1 shows a cross-section of a joined press wall (1); This press wall (υ) narrows down the protruding convex part (3) at the lower end in the longitudinal direction and flattens it into a flat concave part (2),
The lower end is a flat portion (4a). This flat i (
4m) has a straight cross section, so this flat part (4m)
a) is welded to a horizontally installed base (63), and further the base (68) is fixed to the upper end of the transverse bulkhead (60), and the lower surface of the upper deck (62) is welded to the lower surface of the upper deck (62). The angle of inclination α where (3) is narrowed down must be equal to or greater than the angle of repose of the loaded grain such as powder or lump ore to be loaded into the ship's hold.
During loading or unloading, the aforementioned cargo grains accumulate there, so it is necessary to set an angle greater than that angle (approximately 35 degrees).

The upper school (61) of the transverse bulkhead (60) is usually a wall structure constructed by erecting angle steel etc. at equal intervals, but as in this example, there are flat parts (4) (4B) at both ends.
By replacing the press wall (1) with
The necessary and sufficient strength can also be obtained.

FIG. 6 shows another embodiment, in which the press wall (1) of the present invention is used as a partition wall (stay wall) of a superstructure (70) of a living quarters of a ship. The flat parts (4) (4B) of the press wall (1) are welded to the beams or webs of the accommodation superstructure (70). It is a common practice to use a press wall as this type of partition wall, but as mentioned above, with the conventional press wall, the uneven parts interfere with welding and it takes a lot of effort, whereas the press wall of the present invention By installing the wall (1), the number of welding steps is reduced by more than 30 inches compared to the conventional method.

[Effects of the Invention] According to the press wall having the above configuration, the continuity at the joint between the press wall and the welding member is improved due to the flat portions provided at both longitudinal ends of the uneven length of the press wall. As a result, it has the excellent effect of increasing the strength of members near the joint and joint strength, and significantly reducing the number of welding steps.
