DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete panel mounting structure applied to repair of a continuous wall (hereinafter referred to as "bank protection wall or retaining wall") mainly constructed of steel sheet pile facing a river or the like.

[0002]

2. Description of the Related Art Steel sheet piles are sometimes used for construction of revetment walls constructed on shores such as rivers and lakes because the construction period is relatively short. In addition, a concrete panel as a decorative panel may be attached to a revetment wall made of a steel sheet pile so as to cover an upper end and a wall surface of the steel sheet pile for the purpose of makeup.

[0003] As this type of decorative panel, a decorative panel integrally formed in an inverted L-shape from a horizontal portion covering an upper end portion of a steel sheet pile and a vertical portion covering a wall portion is used. In many cases, two portions at the lower ends of the horizontal portion and the vertical portion are fixed to the steel sheet pile by bolting.

[0004]

In this case, in many cases, the upper ends of the steel sheet piles do not have the same height due to a driving error of the steel sheet piles, and are often uneven. For this reason, if the decorative panel is attached directly on the steel sheet pile, the decorative panel will be in the horizontal direction (normal direction for rivers) or perpendicular to it (for rivers, perpendicular to the normal line). ) Or inclining in both directions, and furthermore, there is a step between adjacent decorative panels, so that the horizontal part and the vertical part of the decorative panel are not flush, and the decorative panel cannot be mounted accurately. .

[0005] In addition, when attaching the decorative panel, bolting the lower end of the vertical portion is often performed underwater in the case of a revetment wall, so the work must be performed by a diver, and the work is generally performed. It was annoying and the work was very troublesome.

The present invention has been proposed in order to solve the above-mentioned conventional problems. When repairing a revetment wall or a retaining wall made of a steel sheet pile with a concrete panel, the upper end of the steel sheet pile is made uneven. An object of the present invention is to provide a concrete panel mounting structure that can accurately and securely mount a concrete panel without any influence.

[0007]

In the concrete panel mounting structure according to the present invention, a horizontal beam is attached to the upper end of a continuous wall made of steel sheet pile along the continuous wall, and a plurality of horizontal beams are mounted on the horizontal beam. attached to a predetermined distance along the horizontal plate projecting from the fixing bolt to said continuous wall, said concentrated
Slightly larger than the outer diameter of the fixing bolt
The larger fixing hole and the recess located at the upper end of this fixing hole
Provided, and the fixing bolt is passed through the fixing hole.
And the male thread at the upper end is projected into the recess.
And screw a fixing nut embedded in the recess into the male thread.
And grout around the fixing bolt of the fixing hole and the recess.
Mortar and mortar, respectively.
To achieve.

[0008]

In the concrete panel mounting structure according to the present invention, a horizontal beam is installed at the upper end of a steel sheet pile installed as a continuous wall, and a concrete panel as a decorative panel is bolted on the horizontal beam. The effect of unevenness of the upper end of the steel sheet pile is avoided, and the mounting accuracy of the decorative panel is secured.

[0009]

FIG. 1 is a partial plan view of a revetment wall showing one embodiment of a concrete panel mounting structure according to the present invention, and FIG.
FIG. 3 is a longitudinal sectional view (a river is on the left side and a shore is on the right side in the drawing). FIG. 3 is a plan view of a steel sheet pile before a concrete panel is mounted, showing a horizontal beam and a horizontal plate being mounted.
Is a longitudinal sectional view, and FIG. 5 is a partially enlarged sectional view showing an attached state of a concrete panel.

In the drawings, reference numeral 1 denotes a steel sheet pile forming the body of a revetment wall, 2 denotes a concrete panel (hereinafter referred to as “decorative panel”) attached to the steel sheet pile 1, and 3 denotes an integrated upper end of the adjacent steel sheet pile 1. 4 is a bearing for receiving the horizontal beam 3, 5 and 6 are fixing bolts and nuts for fixing the decorative panel 2 to the upper end of the steel sheet pile 1, and 7 is a fixing bolt 5. It is a horizontal plate for projecting.

The bearings 4 are set horizontally on both sides of the upper end of the steel sheet pile 1 and are horizontally projected by welding. Further, the horizontal beam 3 is placed on the receiving beam 4 on both sides of the upper end of the steel sheet pile 1, is installed horizontally along the steel sheet pile 1, and is integrally fixed to the steel sheet pile 1 and the receiving beam 4 by welding. Have been.

In this case, the horizontal beam 3 is installed such that its upper end surface is located above the upper end of the steel sheet pile 1. The horizontal beam 3 and the receiving beam 4 are made of channel steel.

The horizontal plates 7 are formed in a rectangular plate shape, and are disposed on the left and right horizontal beams 3 at predetermined intervals in the longitudinal direction thereof while being welded. The fixing bolt 5 is vertically projected by welding on the horizontal plate 7. In addition, as shown in the figure, a stud bolt may be used for the fixing bolt, although a headed bolt is used upside down.

The decorative panels 2 are placed on the horizontal burrs 3 one by one, butting each other. The decorative panel 2 includes a horizontal portion 2a covering the upper end of the steel sheet pile 1 and a steel sheet pile 1.
And a vertical portion 2b that covers the wall portion on the river side, and is formed in an inverted L-shape. The surface of the vertical portion 2b is appropriately decorated with tiles or natural stones as necessary.

Further, a plurality of fixing holes 8 through which the fixing bolts 5 can pass are formed in the horizontal portion 2a of the decorative panel 2 corresponding to the fixing bolts 5, and the fixing bolts 5 are inserted into the fixing holes 8. I have.

It is needless to say that the decorative panel 2 is not necessarily limited to a concrete panel, but may be a steel panel or an FRP panel that has been carefully rust-proofed.

The fixing hole 8 is formed slightly larger than the outer diameter of the fixing bolt 5, and a grout material 9 is provided around the fixing bolt 5.
Is filled. At the upper end of the fixing hole 8, a concave portion 10 having a depth that the fixing nut 6 is completely buried is formed, and a male screw portion of the fixing bolt 5 projects into the concave portion 10. Then, the fixing nut 6 is screwed into the male screw portion of the fixing bolt 5, and the mortar 11 is filled in the concave portion 10, so that
The decorative panel 2 is firmly fixed to the horizontal beam 3.

A packing (not shown) is provided at the lower end of the fixing hole 8 so that the grout material 9 immediately after filling does not leak around.
In addition, a seat plate 12 made of stainless steel or the like is laid on the bottom of the concave portion 10 so that the fixing nut 6 is securely tightened.

[0019]

Since the present invention is configured as described above, it has the following effects.

Since the decorative panel is attached by bolting the horizontal part of the decorative panel to the horizontal beam, as long as the horizontal beam is correctly attached,
Even if the upper ends of the steel sheet piles are irregular, the decorative panel can be accurately and reliably attached without being affected by the irregularities.

[0021] Further, since no cast-in-place concrete is used, and a series of operations up to the installation of the decorative panel can be dry construction from the land,
Work efficiency can be reduced, construction costs can be reduced, and the construction period can be shortened.
