DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright used as a horizontal member for supporting a sheet pile at the time of earth retaining in a root cutting work.

[0002] In this specification, the term "aluminum" includes an aluminum alloy in addition to pure aluminum.

[0003]

2. Description of the Related Art For example, a hollow metal member having a rectangular cross section and having a horizontal partition wall therein and cut into a predetermined length is used as the protuberance (see FIG. 2). Such an upset was usually handled by carrying fingers in the openings at both ends, but burrs occur on the end face of the upset when cutting. This may result in injury to fingers due to this burring,
It was dangerous. Therefore, as a conventional bulging (11) that solves such a problem, for example, as shown in FIG. 2, a pair of through holes (13) are formed at both ends of the top wall (12), respectively. A rope (15) is inserted into each of the pair of through holes (13), and both ends of the rope (15) are connected by stoppers (16), thereby forming a loop-shaped hand portion (14). Was.

[0004]

However, the above-mentioned conventional bulging (11) has the following problems.
That is, the rope (1) forming the handhold (14) of the provoked (11)
5) is always located above the top wall (12) of the belly (11), so if you do not use the belly (11), you can store it in a pile of (15) was in the way and could not be stacked successfully. Also, after the bulging (11) is arranged to support the sheet pile for earth retaining work, through the through hole (13) drilled in the top wall (12) of the bulging (11). Rainwater infiltrated into the inside, which was one of the causes of erosion (11) and corrosion.

[0005] The present invention has been made in view of the above problems, and has as its object to provide a stomach that is convenient for storage and hardly causes corrosion.

[0006]

According to the present invention, in order to achieve the above-mentioned object, one horizontal protuberance made of a hollow metal material having at least one horizontal partition wall is provided. A pair of through holes are formed in at least one end of both ends of the partition wall, and a rope is inserted into both through holes and both ends are connected to form a loop-shaped hand-held portion. It is.

[0007] In the above, when the belly is provided with a plurality of horizontal partitions, one of the horizontal partitions may be provided with a pair of through holes. The means for connecting both ends of the rope is not particularly limited, but is usually connected by a ring-shaped, U-shaped or the like stopper.

[0008]

According to the belly of the present invention, a pair of through holes are formed in at least one of both ends of one horizontal partition, and a rope is inserted into both through holes to connect both ends thereof. As a result, a loop-shaped hand-held portion is formed, so that the hand-held portion can be housed inside the prongs except during handling such as transportation, and thereby the prongs can be raised and lowered. Many can be stacked and stored. In addition, since a through hole for inserting a rope is formed in one horizontal partition of the prong, if both ends of the prong are closed with, for example, an end cap, rainwater enters the inside. Nothing.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing one end portion of the belly. In FIG. 1, the bulge (1) is obtained by cutting an aluminum hollow extruded shape having a rectangular cross section and having a horizontal partition (2) at the center of its height to a predetermined length. Horizontal bulkhead
At both ends of (2), a pair of through holes (3) having a circular cross section are provided.
It is opened side by side in the width direction of the bulging (1) by a punch. Then, in each of the pair of through holes (3),
The ropes (5) are inserted, and both ends of each rope (5) are overlapped, and a strip-shaped stopper (6) is
Are strongly wound and connected to form a loop-shaped hand part (4).

[0011] The belly (1) having the above-mentioned structure is handled such as being transported by holding the handholds (4) provided at both ends thereof. On the other hand, except during handling such as transportation, the handhold (4)
Keep inside the prow (1). This makes it easy to store a number of upsets (1) one above the other.

[0012] After the belly (1) is arranged to support the sheet pile for earth retaining work, end caps (not shown) are put on both ends of the belly (1). In this upset (1), a through hole (3) for inserting a rope (5) is made in the horizontal bulkhead (2), and the conventional upset (11) described at the beginning of this document is used. It is not open to the top wall as above, so as long as the end caps are put on the opening at both ends of (1) as described above,
Rainwater is prevented from entering the interior of (1),
Corrosion of the upset (1) is less likely to occur.

[0013]

According to the protuberance of the present invention, a pair of through holes are formed in at least one end of both ends of one horizontal partition, and a rope is inserted into both through holes, and both ends are formed. By being connected, a loop-shaped hand-held portion is formed, so that the hand-held portion can be stored in the inside of the belly except during handling such as transportation. Because you can stack a large number of stakes up and down,
Convenient for storage. In addition, since the through hole for inserting the rope is made in the horizontal partition of the bulge and is not drilled in the top wall as in the conventional example described at the beginning of this manual, the ridge is used to support the sheet pile. After that, as long as the openings at both ends are closed with, for example, end caps or the like, rainwater does not enter into the inside, thereby making it unlikely that the stomach is corroded.
