Description

本発明は、桟橋の支柱同士を連結するための桟橋構築用梁及びこの梁を用いた桟橋構築方法に関する。   The present invention relates to a pier construction beam for connecting pier columns to each other and a pier construction method using the beam.

現在我が国において、道路整備のできていない急峻な山岳地や、水量変化の大きい河川等の土木工事を行う際には、前処理付帯工事として建設機械の搬入路の確保は必要不可欠となっており、仮桟橋工事等により搬入路を確保した後に本格的な土木工事を行っているのが一般的である。
このような仮桟橋の構築において、桟橋の上部パネルを支える支柱の長さがある程度長くなると、図10に示すように隣り合う支柱(A)の間を繋ぎ材(B)とブレス材(C)とからなる梁によって連結している。
従来、このような梁の連結作業は、現場にて、取付金具(D)を支柱(A)に溶接し、取付金具(D)に繋ぎ材(B)及びブレス材(C)をそれぞれ溶接することにより行われていたが、このような従来の作業方法は、高所作業であるために作業に大きな危険を伴う上に、現場作業であるため品質管理が困難であり、しかも作業者のための足場の構築が必要となり、施工期間が長くなるという問題があった。
さらには、切断や溶接作業時に発生する火花によって山火事を引き起こす危険性があり、また一旦設置した梁は再使用することができないため、環境保全や資源保護の観点からも好ましくなかった。
In Japan, when carrying out civil engineering work on steep mountainous areas where roads are not well-developed and rivers with large changes in water volume, it is indispensable to secure a construction machinery carry-in route as a pre-treatment incidental work. In general, full-fledged civil engineering work is carried out after securing a carry-in route by temporary pier construction or the like.
In the construction of such a temporary jetty, when the length of the support supporting the upper panel of the jetty is increased to some extent, the connecting material (B) and the brace material (C) are connected between the adjacent support (A) as shown in FIG. They are connected by a beam consisting of
Conventionally, such a beam connecting operation is performed by welding the mounting bracket (D) to the support column (A) and welding the connecting material (B) and the brace material (C) to the mounting bracket (D) on site. However, this conventional work method is a work at a high place, which poses a great risk to the work and is difficult to control quality because it is a field work. There was a problem that the construction period of the construction was necessary and the construction period was long.
Furthermore, there is a risk of causing a forest fire due to sparks generated during cutting and welding operations, and once installed beams cannot be reused, it is not preferable from the viewpoint of environmental protection and resource protection.

このような実情に鑑みて、本願出願人は、桟橋の支柱間への梁の設置を安全且つ迅速に行うことができる伸縮梁及びこの伸縮梁を用いた桟橋の構築方法を既に提案している(特許文献1参照)。
この開示技術は、上記した従来技術が抱える多くの問題点を解決することが可能な優れた技術であったが、梁を構成する繋ぎ材を油圧シリンダ等の伸縮可能な構造としたものであるから、梁自体がコスト高となるとともに、経時的な油圧低下により支柱から梁が外れてしまうおそれがあった。
In view of such a situation, the applicant of the present application has already proposed a telescopic beam capable of safely and quickly installing a beam between the pier columns and a method for constructing a pier using the telescopic beam. (See Patent Document 1).
This disclosed technique is an excellent technique capable of solving many problems of the above-described conventional technique, but the connecting material constituting the beam is made to be a stretchable structure such as a hydraulic cylinder. Therefore, the cost of the beam itself is increased, and the beam may be detached from the column due to a decrease in hydraulic pressure over time.

It is comprised from a part (52) and the flat flange part (53) each arrange | positioned up and down so that these cylindrical parts (51) and the extension part (52) may be pinched | interposed.
The shape of the cylindrical portion (51) can be set in accordance with the cross-sectional shape of the support column. For example, when the cross-sectional shape of the support column is circular (for example, a steel pipe), it may be cylindrical as illustrated. In the case where the cross-sectional shape of the support is H-shaped (for example, H-shaped steel), it may be a rectangular tube.
The cylindrical portion (51) is divided into two in the axial direction, and the joining plates (54) provided on the outer peripheral surfaces of the two semi-cylindrical portions are aligned with each other, and bolts are inserted into the through holes (55) and fixed. To be united.

図4は、本発明に係る桟橋構築用梁(1)を支柱(61)(62)に取り付けた状態を示す図であって、(a)は平面図、(b)は正面図である。
本発明に係る桟橋構築用梁(1)は、図示の如く、支柱(61)(62)に固定された筒状接続体(5)の延出部(52)と固定板(4)とを重ね合わせた状態として、両者をボルトで接合することにより、支柱(61)(62)に対して固定される。
FIG. 4 is a view showing a state where the pier construction beam (1) according to the present invention is attached to the support columns (61) and (62), where (a) is a plan view and (b) is a front view.
The pier construction beam (1) according to the present invention comprises an extension part (52) of a cylindrical connecting body (5) fixed to a support column (61) (62) and a fixing plate (4) as shown in the figure. In a superposed state, the two are joined to each other by bolts, and fixed to the columns (61) and (62).

以下、本発明に係る桟橋構築用梁を用いた桟橋構築方法について、図面を参照しつつ説明する。
先ず、地面(12)上に支柱(61)(62)を立設した後、これら支柱の上にパネル(71)を載設し、パネル(71)上にクレーン(8)を設置し、図5に示すように、クレーン(8)にて次のパネル(72)を吊り上げて既設のパネルに並べて、PC鋼線(9)により両パネルを連結する。
それから、図6に示すように、クレーン(8)を利用してパネル(72)の上にテーブルマシン(10)を据え付けて地面(12)を削孔した後、図7に示すように、削孔によりできた孔に支柱(63)を打込んで柱頭とパネル(72)を固定する。
上記した如く立設された支柱には、その外周面に高さ方向所定間隔(梁(1)の繋ぎ材同士の間隔)で筒状接続体(5)が固定される。この固定は、支柱を立設した後に行ってもよいし、予め筒状接続体(5)が固定された支柱を地面(12)上に立設してもよい。
Hereinafter, a pier construction method using a pier construction beam according to the present invention will be described with reference to the drawings.
First, after setting up the columns (61) and (62) on the ground (12), the panel (71) is mounted on these columns, and the crane (8) is installed on the panel (71). As shown in FIG. 5, the next panel (72) is lifted by a crane (8) and arranged on an existing panel, and both panels are connected by a PC steel wire (9).
Then, as shown in FIG. 6, a table machine (10) is installed on the panel (72) using a crane (8) to cut the ground (12), and then, as shown in FIG. The pillar (63) is driven into the hole made by the hole to fix the stigma and the panel (72).
The cylindrical connecting body (5) is fixed to the support column erected as described above at a predetermined interval in the height direction (interval between the connecting members of the beams (1)) on the outer peripheral surface thereof. This fixing may be performed after the column is erected, or a column to which the cylindrical connector (5) is fixed in advance may be erected on the ground (12).

次いで、図8に示すように、梁(1)を、繋ぎ材(2)と支柱(62)(63)とが直角方向となるようにクレーン(8)にて吊り下げ、隣り合う支柱(62)(63)の間の所定の高さ位置まで降下させ、固定板(4)と延出部(52)とが重なるようにする。ここで、支柱の打ち込み位置の誤差を吸収できるように、延出部(52)の面積を少し広めに設計しておくことが好ましい。
また、クレーン(8)のフックと梁(1)との間に、図8に示すような断面コの字状のガイド部材(11)を介装すると、ガイド部材(11)の開口部にパネル(72)を入れることによって、梁(1)の位置決めを容易且つ確実に行うことが可能となるため好ましい。
Next, as shown in FIG. 8, the beam (1) is suspended by the crane (8) so that the connecting material (2) and the columns (62) (63) are perpendicular to each other, and the adjacent columns (62) ) (63) to a predetermined height position so that the fixing plate (4) and the extending portion (52) overlap. Here, it is preferable that the area of the extension part (52) is designed to be slightly larger so that the error of the striking position of the support can be absorbed.
When a U-shaped guide member (11) as shown in FIG. 8 is interposed between the hook of the crane (8) and the beam (1), a panel is formed at the opening of the guide member (11). It is preferable to insert (72) because the beam (1) can be positioned easily and reliably.

固定板(4)と延出部(52)とが重なった状態で、両者を万力等で仮固定し、固定板(4)に設けられた貫通孔(43)にボルトを挿通して、固定板(4)と延出部(52)とをボルト締めにより固定する。このとき、延出部(52)に穴が無い場合には、現場にてドリル、パンチ、ガス等を用いて穴を開けて、この穴と貫通孔(43)とを合わせてボルトを挿通すればよく、延出部(52)に長穴が設けられている場合には、この長穴と貫通孔(43)とを合わせてボルトを挿通すればよい。この作業は、例えば上から吊るしたゴンドラに乗って行うことができる。   In a state where the fixing plate (4) and the extending portion (52) overlap, both are temporarily fixed with a vise and the like, and a bolt is inserted into the through hole (43) provided in the fixing plate (4). The fixing plate (4) and the extension part (52) are fixed by bolting. At this time, if there is no hole in the extension part (52), a hole is drilled on the site using a drill, punch, gas, etc., and the bolt is inserted through this hole and the through hole (43). What is necessary is just to insert a volt | bolt combining this elongate hole and a through-hole (43), when an elongate hole is provided in the extension part (52). This operation can be performed, for example, on a gondola suspended from above.
