〔産業上の利用分野〕
この考案は護岸用等に使用されるプレキヤスト
コンクリート製矢板に関するものである。[Detailed description of the invention] [Industrial field of application] This invention relates to precast concrete sheet piles used for seawalls, etc.
近年矢板の背面度中にアンカーとしての杭を打
ち込み、この杭と矢板とを略水平な鉄筋等により
連結し、矢板の土圧抵抗力を高める方法が採られ
ることがあるが、この場合には矢板に鉄筋を繋止
する手段を予め施しておくことが望ましい。
In recent years, a method has been adopted in which a pile is driven into the back of the sheet pile as an anchor, and the pile and the sheet pile are connected with substantially horizontal reinforcing bars to increase the earth pressure resistance of the sheet pile. It is desirable to provide a means to tie the reinforcing bars to the sheet piles in advance.
この考案はこうした方法に対応してなされたも
ので、矢板に鉄筋を繋止する補強板を形成してお
くことにより杭との連結を容易にしようとするも
のである。 This idea was developed in response to such a method, and aims to facilitate the connection with piles by forming reinforcing plates that connect the reinforcing bars to the sheet piles.
本考案においては、矢板は両側部が垂直に屈折
し、かつ長手方向に連続して形成されて断面コ字
状に製作され、矢板内壁面の全周と一体に平行板
体状に補強板が形成され、補強板に鉄筋挿通孔が
穿設されることにより上記課題を解決する。
In the present invention, the sheet pile is bent vertically on both sides and is formed continuously in the longitudinal direction, so that it has a U-shaped cross section, and a reinforcing plate is provided in the shape of a parallel plate integrally with the entire circumference of the inner wall surface of the sheet pile. The above problem is solved by forming reinforcing bars and having reinforcing bar insertion holes drilled in the reinforcing plate.
この鉄筋挿通孔において矢板と杭とが連結用の
鉄筋により連結される。 In this reinforcing bar insertion hole, the sheet pile and the pile are connected by a connecting reinforcing bar.
以下本考案を一実施例を示す図面に基づいて説
明する。
The present invention will be explained below based on the drawings showing one embodiment.
このプレキヤストコンクリート製矢板Ａ（以下
矢板Ａ）は第１図に示すように両側部が垂直に屈
折した断面コ字状の形状をしたもので、対向した
両屈折部１，１間に内壁面２の全周と一体に平行
板体状の補強板４が形成され補強板４には鉛直方
向に鉄筋挿通孔３が穿設されている。 This precast concrete sheet pile A (hereinafter referred to as sheet pile A) has a U-shaped cross section with both sides bent vertically, as shown in Figure 1, and the inner wall surface is between the opposing bent parts 1 and 1. A reinforcing plate 4 in the form of a parallel plate is formed integrally with the entire circumference of the reinforcing plate 2, and a reinforcing bar insertion hole 3 is perforated in the reinforcing plate 4 in the vertical direction.
この補強板４に設けられた鉄筋挿通孔３に第２
図のように連結鉄筋５を挿通し、第３図のように
矢板Ａと杭６とを連結する。 A second reinforcing bar insertion hole 3 provided in this reinforcing plate 4
A connecting reinforcing bar 5 is inserted as shown in the figure, and the sheet pile A and the pile 6 are connected as shown in FIG. 3.
杭６は矢板Ａ垂直方向の地山に打ち込まれ、連
結鉄筋５はその頭部に結ばれる。 The pile 6 is driven into the ground in a direction perpendicular to the sheet pile A, and the connecting reinforcing bar 5 is tied to its head.
矢板Ａと杭６との連結は鉄筋挿通孔３に鋼棒や
ボルトを挿通し、この両端に連結鉄筋５を結び付
けて行つてもよい。 The sheet piles A and the piles 6 may be connected by inserting steel rods or bolts into the reinforcing bar insertion holes 3 and tying the connecting reinforcing bars 5 to both ends of the steel rods or bolts.
補強板４は一段に限らず数段並列して立設して
もよく、その場合対向する補強板４，４の鉄筋挿
通孔３，３間に鋼棒等が挿通され、この両端に連
結鉄筋５が結び付けられる。また補強板４の鉄筋
挿通孔３は一個でも差し支えない。 The reinforcing plates 4 are not limited to one level, but may be installed in several levels in parallel. In this case, a steel rod or the like is inserted between the reinforcing bar insertion holes 3, 3 of the opposing reinforcing plates 4, 4, and connecting reinforcing bars are inserted at both ends of the reinforcing plates 4. 5 is tied. Further, the reinforcing plate 4 may have only one reinforcing bar insertion hole 3.
なお補強板４はこの矢板背面に土が盛られるこ
とによつて矢板Ａの転倒モーメントを小さくする
機能も有する。 The reinforcing plate 4 also has the function of reducing the overturning moment of the sheet pile A by filling the back surface of the sheet pile with soil.
この考案は以上の通り連結鉄筋は補強板の挿通
孔にたやすく挿通することができ現場において矢
板に直接連結鉄筋をつなぎ留めることができるの
で杭との連結を容易に行うことができる。また矢
板は補強板と一体となつているから折曲部の補強
ができその厚みを薄くすることができる。
As described above, with this invention, the connecting reinforcing bars can be easily inserted into the insertion holes of the reinforcing plate, and the connecting reinforcing bars can be tied directly to the sheet piles at the site, making it easy to connect them to the piles. Also, since the sheet pile is integrated with the reinforcing plate, the bent portion can be reinforced and its thickness can be reduced.
