この発明は桟橋等を構成する多柱式床組構造に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-column floor assembly structure constituting a pier or the like.
従来実施されている鉄筋コンクリート構造の桟
橋は、その柱をコンクリートスラブ中に外径以上
埋込むのでスラブの下側配筋を切断し、アンカー
鉄筋が必要であり、型枠も多量に必要として施工
性が悪く、かつ自重が相当に大きくなる。また鋼
構造の桟橋では柱と鋼製梁あるいは桁との現場溶
接の信頼性が十分でなく、柱の打込み精度によつ
て梁、桁の所要長さが多少変化することは免れ
ず、柱の配列の寸法誤差を吸収しにくく、施工性
がよくない。 In conventional reinforced concrete structure piers, the pillars are embedded in concrete slabs that exceed the outside diameter, so the lower reinforcement of the slab needs to be cut, anchor reinforcing bars are required, and a large amount of formwork is required, making construction difficult. is poor, and its own weight becomes considerably large. In addition, for piers with steel structures, the reliability of on-site welding between columns and steel beams or girders is not sufficient, and the required length of beams and girders will inevitably change somewhat depending on the accuracy of the column driving. It is difficult to absorb dimensional errors in the array, and construction workability is poor.
この発明は前記従来の問題点を解消すべく開発
したもので、現場溶接を省き、信頼性の高い組立
構造で、しかも現場での調整が容易な構造を提供
することを目的としたものである。 This invention was developed to solve the above-mentioned conventional problems, and aims to provide a structure that eliminates on-site welding, has a highly reliable assembly structure, and is easy to adjust on-site. .
以下その詳細を図示した実施例によつて説明す
る。 The details will be explained below with reference to illustrated embodiments.
図においてＡは格子状の床組、Ｂは海底地盤に
打込まれて樹立された鋼管等からなる柱材を示
す。 In the figure, A shows a lattice-like floor structure, and B shows pillars made of steel pipes etc. that are driven into the seabed.
床組ＡはＩ形鋼等の鋼桁１を溶接等により組立
てて格子状枠を構成している。なおこの格子状枠
は適当な大きさにブロツク化して工場生産する。 The floor assembly A is constructed by assembling steel girders 1 such as I-beams by welding or the like to form a lattice frame. Note that this lattice frame is produced in a factory in blocks of appropriate size.
格子状枠によつて形成される枠目の中央部には
鋼管または鋳鋼性の筒体２を配置し、かつこの筒

ト３で支持してある。すなわちブラケツト３の一
端を筒体２に溶接等で固定し、他端を鋼桁１に溶
接等で固定してある。 A cylindrical body 2 made of a steel pipe or cast steel is placed in the center of the frame formed by the lattice frame, and this cylindrical body 2 is supported by a bracket 3 made of a shaped steel projecting from a steel girder 1. There is. That is, one end of the bracket 3 is fixed to the cylindrical body 2 by welding or the like, and the other end is fixed to the steel girder 1 by welding or the like.
柱材Ｂの上部外周にはリング状の受ブラケツト

させる。なお筒体２の頂部に、モルタル充填孔５
を設けた蓋体６を設けてこの蓋体６を柱材Ｂの頂
部にのせて支持させることもできる。 A ring-shaped support bracket 4 is welded and protrudes from the upper outer periphery of the column B, and the column B is designed to support the entire weight of the floor assembly and the heavy construction machinery and materials placed on the floor assembly. Drive a sufficient number of pillars B into the ground in advance, and replace the cylinders 2 of floor assembly A with pillars B.
It is fitted onto the outer periphery of the bracket and temporarily received with the receiving bracket 4. Note that there is a mortar filling hole 5 at the top of the cylinder 2.
It is also possible to provide a lid body 6 with a 3-dimensional structure and place the lid body 6 on the top of the pillar B to support it.
次いで筒体２と柱材Ｂとの間にモルタル、コン
クリート等のモルタル類７を充填し、併せて柱材
Ｂの上部内にもモルタル類を充填する。なお、柱
上部内へのモルタル類充填深さは、柱体の局部座
屈を防止するため筒体２の下端から0.5D1以上下
方（D1は柱径）とすることが望ましい。 Next, a mortar 7 such as mortar or concrete is filled between the cylinder 2 and the column B, and the upper part of the column B is also filled with mortar. Note that the depth of filling the mortar into the upper part of the column is preferably 0.5D 1 or more below the lower end of the cylinder 2 (D 1 is the column diameter) in order to prevent local buckling of the column.
なお柱材Ｂの上部は受ブラケツト４を溶接した
短筒状のものを打込み後切揃えた柱上に現場溶接
等で取付けるようにすることができる。 Incidentally, the upper part of the column B may be a short cylindrical member to which the receiving bracket 4 is welded, and may be attached by on-site welding or the like onto the column which is cut and aligned after driving.
筒体２の長さＬは0.5D1≦Ｌ≦2D1であり、筒
体２の厚さt2、柱材Ｂの厚さt1はD1／t1≦D2／t2
の関係にあるようにする。（D2は筒体２の径）
以上の床組Ａ上には覆工板等のプレキヤスト床
板８を載置するか、あるいは薄くスラブコンクリ
ートを打設してもよい。 The length L of the cylinder 2 is 0.5D 1 ≦L≦2D 1 , and the thickness t 2 of the cylinder 2 and the thickness t 1 of the column B are D 1 /t 1 ≦D 2 /t 2
so that there is a relationship between (D 2 is the diameter of the cylindrical body 2) A precast floor board 8 such as a lining board may be placed on the above floor assembly A, or a thin slab concrete may be cast.
他の実施例として床組Ａの格子部材をコンクリ
ート９中に完全に埋込むようにしたいわゆる鉄骨
コンクリート床版とすることもできる。この場合
筒体２の外周にはスパイラル状またはリング状の
ジベル１０を突設し、また鋼桁１、ブラケツト３

体と鉄骨格子材間の力の分散を計るのが望まし
い。 As another example, a so-called steel-framed concrete floor slab in which the lattice members of the floor assembly A are completely embedded in the concrete 9 may be used. In this case, a spiral or ring-shaped dowel 10 is provided on the outer periphery of the cylinder 2, and a steel girder 1 and a bracket 3 are provided.
It is desirable to dissipate the force between the column and the steel frame by providing a dowel 11 on the web.
なお筒体２の内径と柱材Ｂの外径との差、ｅ＝
D2−D1−2t2は施工性からは大きい方が望ましい
が、ｅが大きくなり過ぎるとその接合部の耐荷力
変形能が低下するので一般には、30cm未満とし、
その差が30cm以上になる場合にはジベル等の突設
のみならずその間にスパイラル筋１２等のリング
状補強筋を設けるのが望ましい。 Note that the difference between the inner diameter of the cylinder 2 and the outer diameter of the column B, e=
D 2 −D 1 −2t 2 is preferably larger from the viewpoint of workability, but if e becomes too large, the load-bearing deformation capacity of the joint will decrease, so it should generally be less than 30 cm.
If the difference is 30 cm or more, it is desirable not only to provide a protrusion such as a dowel, but also to provide a ring-shaped reinforcing bar such as a spiral bar 12 between them.

The cylindrical body 2 is welded on site. Further, when part of the column B including the diagonal column B' is to be later cast, the cylinder body 2 including the one for the diagonal column can be used as a guide.

工性が向上する。 The present invention has the above-described configuration, and since on-site welding is omitted from the main joint between the column upper part and the floor assembly, a highly reliable joint structure can be obtained. In addition, by appropriately selecting the inner diameter of the cylinder 2, errors in the driving position of the pillar materials can be absorbed, making it possible to prefabricate the floor assembly and improving workability.
