Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shell-type water gate as a long span water gate for river water use.

[Conventional technology]

FIG. 4 shows an example of such a shell-type water gate, in which horizontal aggregates 2 are arranged around separators 1 provided at intervals, and an outer panel consisting of a skin plate 3 and a back plate 4 is provided on the outer surface. It will be put up.

Although not shown, both ends are closed with side plates, and the guide groove of the pier is moved up and down by sliding rollers provided on the side plates. Note that 5 indicates a space provided in the separator.

In such a shell type water gate, the bottom corner part 6
is the joint between the skin plate 3 and the back plate 4, and the skin plate 3 and the back plate 4 are fillet welded to each other, and the skin plate 3 is extended downward from this welding point to form a lip 7. A gasket made of watertight rubber 8 is attached here.

[The problem that the idea aims to solve]

However, in the conventional shell-type water gate shown in FIG. 4, the welding point between the skin plate 3 and the back plate 4 is located at the lower end corner 6 where stress is concentrated, which is inconvenient in terms of strength, and there is a drain hole. 9 is inconvenient in terms of strength, and is placed away from the corner. However, the angle between the skin plate and the back plate must be 90 degrees or less for structural reasons, so water does not accumulate in the corner. I will pray. This water was a cause of corrosion at the welded parts.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a shell-type water gate that can separate a welding part from a lower end corner where stress is concentrated, thereby protecting against corrosion and improving strength.

[Means to solve the problem]

In order to achieve the above object, the present invention arranges horizontal aggregates around separators provided at intervals,
In a shell-type water gate with an outer panel consisting of a skin plate and a back plate, the skin plate and back plate are joined at the landing part made of an extruded member with joining leg pieces, and the lower corner part is joined. The structure and the landing part made of extruded material are:
A leg piece for connecting to the skin plate and a back plate is protruded so that the upper part of the leg piece for the ground contact part is divided into two parts, and the leg piece for connecting to the back plate is longer than the leg piece for connecting to the skin plate. The main idea is to be low and protrude downward.

[Effect]

According to the present invention as set forth in claim 1, the lower end corner portion which is the lowest position is constituted by a landing portion made of an extruded shape member provided with a leg piece for joining, so that this landing portion and the skin plate are connected to each other. The welded part with the back plate can be removed from the bottom corner. Also,
Even if water accumulates in the lower corner, it is an extruded shape and has no welded parts, so there is no fear of corrosion and it is strong.

According to the present invention as set forth in claim 2, the leg piece for joining the landing portion to the back plate made of an extruded shape allows water to flow due to the slope, and the water flows in the vicinity of the welded part between the leg piece for joining and the back plate. Water will flow to the drain hole provided in the bottom corner, preventing water from accumulating at the bottom corner.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional side view showing one embodiment of the shell-type water gate of the present invention, and the same components as in FIG. 4 showing the conventional example are given the same reference numerals.

That is, the shell-type water gate of the present invention also has an overall structure in which horizontal aggregates 2 having an L-shaped cross section are arranged around separators 1, which are partition plates provided at intervals, and skin plates 3 and backs are arranged on the outer surface. plate 4
It is the same as the conventional example in that the outer panel is stretched and a space 5 is provided in the center. These separators 1
The skin plate 3 and the back plate 4 are made of aluminum alloy, and the horizontal aggregate 2 is also made of extruded aluminum alloy.

The lower end corner portion 6 is shown in detail in FIG. 2, and the lower end corner portion 6 is constructed by joining the skin plate 3 and the back plate 4 at a landing portion 10 made of an extruded aluminum alloy member.

The landing part 10 has leg pieces 10b and 10c for joining to the skin plate 3 and back plate 4 protruding so that the upper part of the leg piece 10a for the ground contact part is divided into two. Leg piece 1
0c is located at a lower level than the leg piece 10b for joining to the skin plate 3, projects downward, and gradually becomes thinner toward the tip.

Then, the edges of each joining leg piece 10b and 10c are welded to the edges of the skin plate 3 and back plate 4. In addition, the leg piece 10a for the grounding part
An aluminum piece 11 is welded to the outer corner of the branch of the joining leg piece 10c, and is attached to the joining leg piece 10c and the back plate 4 to form the back plate 1 for reinforcement.
2 was welded. In addition, aluminum piece 11
may be omitted and the relevant portion of the extruded shape may be made thick.

A watertight rubber 13 as a gasket is stacked on the ground contact leg piece 10a so that its end protrudes.
It is sandwiched between the contact plates 14 and fixed with bolts 15.

As shown in FIG. 3, the drain hole 9 is formed at the end of the back plate 4 so that the end of this hole 9 is located at the border with the joining leg piece 10c, and this hole 9 is also formed in the back plate 12. A corresponding hole 16 was provided, and a grid 17 for preventing entry of dust etc. was attached to the outside of the hole 16.

In this way, although not shown in the drawings, rollers are provided on the side plates at both ends and are moved up and down with wire ropes, etc., but when lowered, the ground contact leg piece 10a
is grounded and the gate is closed. Furthermore, when the water gate door is lifted, the water that has entered the inside is discharged to the outside from the drain hole 9, but at the lower end corner part 6, water is removed from the connecting leg piece 1.
0c to the drain hole 9, and does not accumulate in the lower corner portion 6.

[Effect of idea]

As mentioned above, the shell type water gate of this invention is
Horizontal aggregate is arranged around separators placed at intervals, and an outer plate consisting of a skin plate and a back plate is stretched on the outer surface, and the lowermost corner part is provided with leg pieces for joining. Since the landing section is made of an extruded section, the welding points between the landing section, skin plate, and back plate can be removed from the bottom corner, and corrosion will not occur even if water accumulates at the bottom corner. There is no risk of this occurring.

In addition, the lower end corner is a part where stress is concentrated, but by not locating the welding part here,
It is possible to make fatigue failure less likely to occur.

Furthermore, the slope of the landing section allows water to flow into the drain hole, thereby preventing water from accumulating at the bottom corner.
