この発明はコンクリート構造物の施工において
利用するコンクリートの打継方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a concrete splicing method used in the construction of concrete structures.
通常RCあるいはSRC構造物等のコンクリート
工事においては、水平あるいは垂直面に打継部が
発生するが、打継部はひびわれ同様、建築物の意
匠上、構造上の欠陥個所となる場合が多い。特
に、地下外壁の垂直打継などにおいては、漏水事
故が発生しやすく、施工の煩雑さから多大な労力
を要する。 Normally, in concrete work such as RC or SRC structures, joints occur on horizontal or vertical surfaces, but joints often become defects in the design and structure of buildings, similar to cracks. In particular, water leakage accidents are likely to occur in vertical joints of underground external walls, and the construction is complicated and requires a great deal of labor.
従来、構造物の外壁垂直打継方法としては、バ
ラ板打継やラス打継の他、種々の方法が工夫され
ている。 BACKGROUND ART Conventionally, various methods have been devised to vertically join the outer walls of structures, including loose board joints and lath joints.

旧手直しの順となる。 Figure 1 shows the conventional method of splicing separate plates.The construction process using this method is: installing the splice formwork, pouring concrete, dismantling the splice formwork, cleaning the splice area, and restoring reinforcing steel. The order will be rework, followed by formwork restoration work.

is a weir plate for forming the RC wall surface, c is a form tie, d is a habata pipe, and e is a square tightening chain that tightens the habata pipe. In addition, a vinyl chloride water stop plate f (bending type) is installed in advance at the joint using a mounting bracket g.
It is designed to be triggered after the formwork is dismantled.
しかし、このバラ板打継工法は施工精度や材料
のコストの面では従来の工法においても比較的好
結果が得られるが、上述した一連の作業にかなり
の手間を要し、施工性が劣るため結局潜在コスト
もかかることになる。 However, although this method can achieve relatively good results compared to conventional construction methods in terms of construction accuracy and material cost, it requires a considerable amount of effort in the series of operations mentioned above and has poor workability. In the end, there are potential costs involved.
また打継面にラスを用いるラス打継工法は施工
性は良いが、ガスの錆による漏水、施工精度およ
びコスト面で劣るなど一長一短があり、いずれの
工法も必ずしも満足の行くものではない。 In addition, the lath joint method, which uses lath for the joint surface, has good workability, but it has advantages and disadvantages, such as water leakage due to gas rust, and is inferior in construction accuracy and cost, and neither method is necessarily satisfactory.
そこで、この発明では特に打継部における止水
性を十分確保した上で、施工性および経済性にも
優れたコンクリートを打継方法を提供することを
目的とした。 Therefore, it is an object of the present invention to provide a concrete splicing method that has excellent workability and economical efficiency while ensuring sufficient water-stopping properties particularly at the spliced joints.
以下、この発明の工法を図示した実施例に基づ
いて説明する。 Hereinafter, the construction method of the present invention will be explained based on illustrated embodiments.

ができる。 FIGS. 2 and 3 show a joint section in this concrete joint method, in which air hoses 1 are lined up at the joint surface, and air is press-fitted into them to be used as a formwork. In the example shown in the figure, a total of four air hoses are attached, two large-diameter air hoses 1a in the center and two small-diameter air hoses 1b on both sides. Depending on the situation, it is sufficient to prepare the necessary number of diameters as appropriate. Further, a water stop plate 3 is inserted between the central air hoses 1a, 1a. If air is forced in in this state, the entire or almost the entire joint surface can be closed with the reinforcing bars 2, the water stop plate 3, etc. sandwiched therebetween.

Air is forced in from here.
なお、図の実施例は垂直な壁体への適用例を示
したものであるが、エアーホースを横方向にして
並らべることによりスラブ打継にも利用できる。 Although the illustrated embodiment shows an example of application to a vertical wall, it can also be used for slab jointing by arranging the air hoses horizontally.

2の復旧手直しが不要となる。 First, the air hose 1 is attached and air is pressurized into the air hose 1. In the figure, 5 is a flap pipe, 6 is a separator, and 7 is a form tie. When concrete is poured and reaches a predetermined strength, the valve 10 of the air hose 1 is opened to evacuate the air. After disassembling the air hose 1, clean and tidy up the spliced part. Finally, the formwork is restored and reworked to complete the joint work. Note that at this time, the reinforcing bars 2 can be worked on as they are, so there is no need to repair the reinforcing bars 2.
この発明は以上の構成からなり、次のような利
点、特徴を有する。 The present invention has the above configuration and has the following advantages and features.
(1) 空気を圧入したエアーホースを並べて打継面

に止水板をエアーホースに挟み込んで保持させ

ができるので、打継面がきれいなことと併せて
高い止水性が得られる。(1) By lining up air hoses filled with air and using them as formwork for the joint surface, leakage of concrete will be eliminated and the joint surface will be clean. In particular, since the water stop plate is held between the air hoses, it is easy to install and can be stored in a predetermined position, resulting in a clean joining surface and high water stop performance.
(2) エアーホースの上下端にU形断面の短筒状端

端迄均等な筒状となつて、しかも迅速に空気を
圧入することができ、また打継面の長さに対応

前記端部金物により打継面の上下端の納まりが
確実にでき施工性にすぐれている。(2) Short cylindrical end fittings with a U-shaped cross section are attached to the top and bottom ends of the air hose, so the air hose has an even cylindrical shape from top to bottom, and air can be quickly injected. The required air hose can be easily obtained by preparing a hose of the required length corresponding to the length of the joining surface and replacing and attaching it to the short cylindrical end fittings at the top and bottom ends. This ensures that the upper and lower ends of the joint surfaces fit together, resulting in excellent workability.
(3) 鉄筋もエアーホースに挟み込んで保持させる
ので、打継部に連続した配筋ができ、鉄筋の手
直しが無く施工性が良いことや材料がいたまな
いことと併せてコスト低減が図れる。(3) Since the reinforcing bars are also held between the air hoses, continuous reinforcing bars can be placed at the joints, and there is no need to modify the reinforcing bars, which improves workability and reduces the cost of materials.
