Abstract

PROBLEM TO BE SOLVED: To make up for the shortage of tensile strength when having assembled a vessel or a bank with a liner plate. SOLUTION: A notched area whose shape is preferably designed to prevent a strip from coming off, is provided in one to three locations along the groove on the outer periphery of a flange in the axial direction of a liner plate 1. This liner plate 1 is jointed with a bolt in every direction, thereby forming a cylinder-shaped structure. The strip 2 is wound up along the groove on the outer periphery of the liner plate 1 and fastened. The strip 2 is so shaped that it may run along the groove of the outer periphery of the liner plate 1. Favorably, the strip 2 is connected with an anchor member which slants a bearing surface and a through hole in conformity with the direction of the strip 2 and fastened. So as to uniform the tensile force, the strip 2 is connected in a plurality of locations on the outer periphery and fastened. The number of winding of the strips 2 is reduced at the upper part while it is increased at the lower part. This construction makes it possible to reduce the number of bolts used when they are jointed to a satisfactory extent.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liner plate cell structure container used for aggregate bottles, silos, aquariums, etc.
The present invention relates to a liner plate cell dam body used for breakwaters, quays, seawalls, artificial islands, etc., and a liner plate used for these materials.

2. Description of the Related Art As shown in FIGS. 13 to 15, a liner plate is provided with a corrugated steel plate 11 curved in an arc shape and provided with a circumferential flange 12 having connecting holes 14 and 15 on four sides and an axial flange 13. Then, the cylindrical structure can be assembled by abutting in the vertical and horizontal directions and bolting them through the connecting holes 14 and 15. The cylindrical structure thus assembled is often used, for example, in a tunnel or a retaining wall 21 for excavating a vertical shaft as shown in FIG.

On the other hand, a corrugated pipe is used for the same purpose as the liner plate. This is a corrugated steel plate without a flange. By stacking the ends and bolting them together, you can assemble earth retaining walls, etc., as well as containers such as aggregate bins, silos, and aquariums. .

Comparing the liner plate and the corrugated pipe, since the flange is provided in the liner plate, in order to join the liner plates to each other, the flanges may be butted to each other and bolted together. This work is performed inside the liner plate. It is advantageous in that it can be performed only. In other words, the work is efficient only because the work is performed only on the inner side, and since no work space is required on the outer side, in the case of a retaining wall or the like, it is not necessary to carry out extra digging or backfilling on the outside. It is also economical that the liner plate requires fewer bolts for joining.

[0005]

Although the liner plate has such advantageous characteristics, it can be used as an aggregate bottle for storing aggregates such as sand and gravel, a silo for storing grass and corn, or an aquarium. There is a problem that the bolt connection in the circumferential direction is weak when assembling the container body such as a breakwater, a quay wall, a revetment, an artificial island, etc. with a predetermined filling material such as sand, gravel, etc. . That is, FIG. 15 and FIG. 15 corresponding to the AA arrow view of FIG.
As shown in, the axial flange 1 of the liner plate 1
Generally, three connecting holes 15 are provided in 3, and when a force is applied from the outer side to the inner side of the cylindrical structure such as a retaining wall, the force applied to the bolt joint is compressed. Since this is a force, this is sufficient strength, but when a force is applied from the inside to the outside of a cylindrical structure such as the container or bank, the force applied to the bolt joint becomes a tensile force, and the number of bolts Since it has a small amount, it cannot withstand a large force and there is a risk of breaking. Moreover, since the connection holes 15 are provided at four positions inside the corrugated steel plate 11 of the axial flange 13 as shown in FIG. 15, it is difficult to increase the number.

Therefore, the present invention compensates for the tensile strength in the circumferential direction, which is insufficient when a container or a bank is assembled using a liner plate, and can sufficiently withstand the force from the inside without increasing the number of bolt joints. The purpose is to

[0007]

A liner plate cell structure container of the present invention has a cylindrical structure in which a liner plate is bolted in the vertical and horizontal directions, and a notch is formed in an axial flange along a groove on the outer periphery of the liner plate. A liner plate cell structure container characterized in that a filamentous body is wound and tightened. The linear member can be connected and fastened with a fixing member.The fixing member has a shape that follows the shape of the groove on the outer circumference of the liner plate, and the pressure bearing surface and the through hole are formed depending on the direction of the linear member. Inclined ones are preferred. The filament is preferably connected and tightened at multiple points on the outer circumference, and the number of windings of the filament is small at the top and large at the bottom, and the diameter of the filament is thin at the top, The lower part can be thicker, and the liner plate can be thinner at the upper part and thicker at the lower part. In order to prevent the filaments from falling off, it is preferable to weld a stopper of the filaments to each of a plurality of liner plates, and the shape of the notch should be a shape that prevents the filaments from falling off. The liner plate cell dam body of the present invention is the liner plate cell dam body obtained by filling the inside of the liner plate cell structure container of the present invention with a predetermined filling material. Further, the liner plate of the present invention is a liner plate characterized in that one to three cutouts are formed along the groove portion on the outer periphery of the axial flange, and the shape of the cutouts is that the linear body is not dropped. It is preferable to have a shape to prevent.

In the present invention, the tensile strength, which is insufficient in bolt joining, is supplemented by winding the filament. That is, the tensile force T applied to the cylindrical structure is expressed by the equation (1) equation 1 with respect to the force f applied from the inner side to the outer side of the cylindrical structure, and the tensile force T is applied from the inner side to the outer side of the cylindrical structure. The applied force f is a function of the height h as shown by the equation (2). If the tensile strength F of the bolted portion of the liner plate is larger than the tensile force T, it can withstand, but if the tensile strength F is smaller than the tensile force T, reinforcement by a linear member is required. Therefore, the tensile strength F and the tensile force at the height position of each liner plate are required. Compared with T, no reinforcement is required at the height F ≧ T, but F
At a height of <T, bolting alone cannot withstand without reinforcement. As shown in FIGS. 13 and 15, the liner plate 1 has a groove portion on the outer periphery which is suitable for running the linear body. Therefore, as shown in FIG. 1, the linear body 2 is formed along the groove portion. Wrap and tighten. At this time, the axial flange 13 of the liner plate 1 projects into the groove portion and interferes with the winding of the filamentous body 2. Therefore, as shown in FIG. A normal steel wire can be used for the filament, and a high-strength steel wire can also be used, and the high-strength steel wire is preferable because it can be made thinner than a normal steel wire. Also, a synthetic resin filament may be used.

As shown in FIG. 3, when the cell structure container is filled with, for example, earth and sand to form the artificial island 9, the force f applied from the inside to the outside of the cylindrical structure is small at the upper part and larger at the lower part. Become. Therefore, in response to this, even within a height range in which reinforcement by winding of the filament 2 is required, the number of windings of the filament 2 is reduced in the upper part and / or the wire diameter is small, and in the lower part. It is effective to increase the number of windings of 2 and / or to increase the wire diameter. As shown in FIG. 15 and the like, since there are three grooves on the outer circumference of the liner plate 1, the filamentous body 2 is wound around all three grooves at the lowermost part where a large force is applied, and in the middle there are two upper and lower grooves. Striatum 2 in the groove
It is possible to adjust the number of windings of the filamentous body 2 such that the filamentous body 2 is wound around and the filamentous body 2 is wound only in the central groove portion in the upper part so as to have a strength corresponding to the internal stress. Alternatively, it is possible to select appropriately according to the magnitude of the force, such that only two wires are required at the lowermost part and winding of the filamentous body is not necessary at the upper part.

For the same reason, the liner plate 1 can be made thinner at the upper portion and thicker at the lower portion. For example, since liner plates having a plate thickness of 2.7 to 7.0 mm are commercially available, these may be arranged appropriately.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION For tightening the linear member 2, a turnbuckle 4 generally used for connecting the linear member 2 as shown in FIG. 4 or a toggle mechanism (not shown) can be used. In addition, as shown in FIG. 5A, the fixing member 3 manufactured to match the shape of the groove on the outer periphery of the liner plate 1 is particularly used, and the left and right end members of the fixing member 3 are made to penetrate the ends of the linear members. Alternatively, the nut 8 can be screwed and fastened. In this case, since the linear member 2 wound in close contact with the liner plate 1 is separated from the liner plate 1 at the position of the fixing member 3, as shown in FIG. When the liner plate 1 is perpendicular to the liner plate 1, the nut 8 comes into partial contact. Therefore, as shown in FIG. 5 (c), the bearing surface 3 is arranged so as to be perpendicular to the tangential direction of the filament body 2.
It is preferable to tilt a. Although not shown, it is preferable that the through holes of the filaments are also inclined in the same direction as the tangential direction of the filaments 2. When the fixing member 3 is used, if the fixing member 3 is temporarily fixed to the corresponding portion of the liner plate 1 in advance, the work of tightening the linear member 2 becomes easy.

Further, as shown in FIG. 6, as an example of the fixing member, it is also possible to connect the filaments by using a bearing plate 5 having a shape that follows the shape of the groove on the outer circumference of the liner plate. The pressure plate 5 is provided with two through holes 6 in the horizontal direction as shown in FIG. 4A or in the vertical direction as shown in FIG. As shown in FIG. 7, a terminal 7 is crimped to the end of the filamentous body 2 and a terminal process for threading is performed. Then, as shown in FIG. 6C, the ends of the linear member 2 are penetrated from both sides of the pressure support plate 5, one end is fixed with a nut 8 and the other end is pulled by a retracting jig by about 500 kg. After that, the filament body 2 can be connected by tightening with the nut 8.

The bearing plate 5 shown in FIG. 6 has a total length of 100.
When the radius of the cylindrical structure is large and the radius is about 150 mm, this is sufficient, but when the radius is small, it is preferable to bend along the outer shape of the liner plate. The material of the pressure bearing plate 5 is steel or the like, and can be manufactured by cutting or the like.

FIG. 8 shows a preferred embodiment of the bearing plate 5. FIG. 8A is a side view of the pressure bearing plate 5, and the lower portion of FIG. FIG. 8 (b) is a plan view of the bearing plate 5, where the left bearing surface 5a is inclined by 10 °, the right bearing surface 5b is inclined by 5 °, and the through holes 6a, 6b are also inclined by 10 ° and 5 °, respectively. are doing. FIG. 8 (c) shows the linear body 2 using this bearing plate 5.
It is a top view which shows the situation which connects. The linear body 2 having the nut 8 fixed to the end is passed through the through hole 6b, and the pressure is supported by the pressure bearing surface 5b on the right side. A threaded end 7 is passed through the through hole 6a, tightened with a nut 8, and pressure is supported by the left bearing surface 5a. In this way, the bearing surface and the through hole are inclined according to the direction of the linear body, that is, the bearing surface is perpendicular to the tangential direction in which the linear body separates from the liner plate. By inclining the nuts so that they are in the same direction, it is possible to prevent the nuts from hitting each other at the connection points of the linear members.

The liner plate cell structure container and liner plate cell dam body of the present invention may be a large structure having a diameter exceeding 20 m. However, when the container is so large, the linear body is formed at one place on the circumference. The tension of the filamentous body 2 may not be uniform just by connecting and tightening the two. Therefore, in order to make the tension of the wound wire member 2 uniform on the circumference, the wound wire member 2 is divided into two equal parts, three parts, etc., and the connection and tightening are performed on the outer circumference. It is preferable to carry out at a plurality of locations.

As shown in FIG. 9, it is preferable to weld a stopper plate 18 to the liner plate 1 so that the liner body 2 can be prevented from falling off during work and the work can be carried out smoothly. As the stopper plate 18, one that extends from the upper end to the lower end of the liner plate 1 as shown on the left side of FIG.
As shown on the right side of the figure, a groove extending from the lower half of the groove to which the filament 2 is applied can be used. The left side clasp can be used when winding the linear body many times, and the right side clasp is advantageous in that the linear body can be easily hooked. In addition,
FIG. 9 (b) shows a state in which two kinds of clasps are welded to one liner plate for the sake of illustration. However, in practice, one kind of clasps is used every two or three pieces. It suffices to weld it to each liner plate. In addition to this, as will be described later, it is possible to prevent the filament from falling off by devising the shape of the notch of the axial flange of the liner plate.

The liner plate cell structure container of the present invention is constructed as described above, and since the tensile strength which is insufficient only by the bolt connection is compensated by the winding of the filament body, the aggregate bottle, silo, water tank. It can be used as a container that accommodates an object inside, and therefore exerts a force from the inside toward the outside.

Further, the liner plate cell dam body of the present invention is obtained by filling the inside of the liner plate cell structure container constructed as described above with a predetermined filling material such as earth and sand or gravel. It can be used for the artificial island 9 for installing the bridge piers of the bridge of the sea or lake shown, a revetment, etc.

The liner plate of the present invention is characterized in that one to three cutouts are formed along the groove on the outer periphery of the axial flange. As mentioned above,
Since the axial flange 13 of the liner plate 1 protrudes into the groove and interferes with the winding of the linear body 2, the liner plate of the present invention corresponds to the groove in which the linear body 2 of the axial flange 13 is wound. As shown in FIG. 10, a notch 17 is provided in advance at the location. FIG. 11 corresponds to FIG.
An example of the axial flange 13 of the liner plate of the present invention is shown in the drawing corresponding to the AA arrow view of (a), but if notches 17 are provided at three positions as shown in (a) of the same drawing, It can be used not only when winding three filaments but also when winding two or one, but when two or one is wound, cutouts are placed in two or one place. A liner plate can also be used. In this case, in consideration of the balance of tensile strength, as shown in FIGS. 11 (b) and 11 (c), the notch 17 is formed in the upper and lower parts in the case of two places and in the middle part in the case of one place. . In addition, even if a notch is formed in the axial flange 13, the strength of the liner plate is not affected. Further, the notch can be easily inserted by gas cutting or the like, and it is possible to make the notch not only in the factory but also in the field.

FIG. 12 shows a preferred embodiment in which the notch 17 is shaped so as to prevent the filament from falling off. If the notch having such a shape is formed, it is not necessary to provide a stopper plate or the like for preventing it from coming off.
