DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall used for breakwaters, seawalls and the like.

[0002]

2. Description of the Related Art There are various types of structures, such as a caisson type and a block type, for a breakwater installed at a coast or an entrance of a port or a seawall for a landfill. A curtain wall type breakwater has been proposed in which a steel turret supported by piles and a reinforced concrete breakwater plate are attached.

[0003] As shown in Fig. 8, the breakwater comprises a wall unit 3 made of an elongated rectangular concrete plate, and a frame member 1 which is cast at predetermined intervals in a normal direction. The wall is constructed between the two. Conventionally, in the construction of the wall, the wall unit 3 made of a concrete plate is dropped horizontally between the flanges of the H-shaped steel frame member 1 and stacked upward to form a wall.

[0004]

Since the thickness of the conventional wall unit 3 of the wall is smaller than the distance between the flanges 2 and 2 of the H-shaped steel of the frame member 1, a gap is formed between the wall unit 3 and the inside of the flange. There have been problems in that the wall surface becomes uneven and the wall unit moves due to the wave force and is damaged. For this reason, as a means for eliminating the movement of the wall unit 3 in this gap, a wedge-shaped fixing piece 6 as shown in FIG.

[0005] Since this work is an underwater work by a diver, the workability is poor, it is difficult to obtain a sufficient fixation, and it is dangerous. Moreover, the wedge-shaped fixing piece 6 may come off, so that it cannot be said that this is a sufficient fixing method.

As means for fixing the wall unit 3, it is conceivable to use bolts to the H-shaped steel as the frame material 1. In this case, bolt holes are provided in the wall unit 3 and the frame material 1 in advance. Since it is necessary to insert and tighten the bolts by aligning the holes, a high accuracy of the driving of the frame material is required. There is a problem that the work is extremely difficult because the work is a diver work.

SUMMARY OF THE INVENTION The present invention solves these conventional problems and provides a curtain wall wall in which a wall unit is securely fixed to a frame material without using a fixing piece, a bolt, or the like, and by an extremely simple operation without a diver operation. The purpose is to provide.

[0008]

In order to achieve the above object, according to the present invention, a plurality of wall units having tapered upper and lower corners on one side between the frame members are constructed by dropping the tapered surfaces to face each other. The gist of the present invention is that a curtain wall body is used.

That is, as shown in FIG. 4, a diagonal reaction force P ₁ due to its own weight W is generated on the opposing tapered surface 4 of the wall unit 3 dropped between the flanges 2 and 2 of the frame material 1. As a result, the wall unit rebounds and the horizontal force P ₂ is applied to the frame material.
Will be pressed and fixed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 illustrates a means for constructing a curtain wall of the present invention, FIG. 2 shows a completed curtain wall of the present invention, and FIG. 3 shows a cross section taken along line AA of FIG.

[0011] Between the inner surfaces B of the flanges of a substantially H-shaped frame member 1 made of a commercially available H-section steel or thick steel plate which is vertically installed on the seabed at predetermined intervals in the normal direction of the breakwater or seawall, A plurality of wall units 3 are stacked to form a curtain wall.

[0012] wall unit 3 is made of reinforced concrete, as the dimension B is less than the thickness B ₁ between the flanges inner surface of the frame member 1, it is capable fitted in the flange, and tapered upper and lower corners of one side Must be formed.

As shown in FIG. 1, the wall unit 3 having such a shape is suspended one by one by a crane with the tapered surfaces 4 facing each other between the flanges 2 and 2 of the frame member 1 and dropped horizontally. As shown in FIG. 4, a reaction force is generated in the dropped wall unit 3 in a direction in which the own weight W of the wall unit repels each other at the tapered surface 4 of the opposing wall unit. It moves to the inner side of the flange of the frame member 1 and is restricted by contact.

A lower end stopper 7 for supporting the wall unit 3 is provided at a lower end of the wall below the frame member 1, and an upper end stopper for preventing the wall unit 3 from floating at the upper end of the wall. 8 is provided by means such as welding.

FIG. 5 shows another example of the present invention, in which the thickness B ₁ of each wall unit 3 is slightly smaller than the dimension B between the inner surfaces of the flanges of the frame 1. In this way, the irregularities on the surface of each wall unit 3 can be reduced. FIG. 6 shows a wall unit 3 in which a through hole 5 is provided, which is suitable for use as a curtain wall breakwater or breakwater which requires seawater exchangeability. FIG. 7 shows a use state in which the curtain wall of the present invention is attached to the front surface of the steel tower 10.

[0016]

As described above, according to the present invention, a plurality of wall units are formed on a substantially H-shaped frame member which is vertically installed at a predetermined interval and whose upper and lower corners on one side are tapered. Since the curtain wall is a wall constructed by dropping the tapered surface between the frame members to form a wall, all operations can be performed extremely easily on the water surface, and the wall unit is securely and securely fixed to the frame member can do.
