の薄板製箱などの箱体の埋設によつてもよい。 The above is the same for the ordinary connection block 31 shown in FIG. 2, but in the connection block 1 of the present invention,
On the inner surface 10 of the corner 6, which is the side surface 9 of the block 1, a recess 11 is formed in the block body 1'.
If the insertion hole 3 is cut through the corner 6, the insertion hole 3 is cut at the corner 6, and the insertion holes 3, 3 are opened in both the recessed end faces 29, 30. The recessed portion 11 may be formed by forming a recess in the block 1, or by embedding a box such as a box made of a thin plate such as an iron plate.

であるから、取付部１３，１４も含めての連結部
品１２が変位し得る余裕を持たせるのである。 By forming the length in the direction of the insertion hole 3 of the connecting component 12 to be shorter than the inner length of the recessed part 11 in the direction of the insertion hole 3, the length in the direction of the insertion hole 3 of the connecting part 12 accommodated in the recessed part 11 There is a margin in the recess 11 that allows for the displacement of the connecting part 13. This margin is a space to avoid pressure contact between the two due to relative displacement of the connecting part 12 with respect to the recess 11, as will be described later. , 14 is provided to allow the connecting part 12, including the connecting parts 12, to be displaced.

変形し難い適宜の形態を採ることができる。 It is also possible to assume that the connecting component 12 fills in the absence of the connecting member 2 in places where the connecting member 2 does not exist and exhibits fastening strength by being connected to the connecting member 2, so these loads should be taken into consideration. steel material,
Other materials with excellent strength can be used to take an appropriate shape that is difficult to deform, such as the box shape shown in the figure.

た。 5 to 10 show two examples of the interior of the recessed portion 11.
The connecting part 12 has a box shape, and is elastically supported by interposing a filling layer 17 having elasticity such as natural rubber or urethane rubber between the mounting parts 13 and 14 and the recessed part 11, and a washer 18 is interposed therebetween. and tighten the nut 19. In the first example of FIGS. 5, 6, and 7, the concave portion 11
The connecting part 12 was inserted into the filling layer 17 with or without adhesion, and the filling layer 17 was provided with a grout injection hole 20 for blocking water from entering the recessed part 11.
In the second example shown in FIGS. 8, 9, and 10, an anchor plate 21 was further interposed to even out the stress, and the nut was tightened, and a grout injection hole 20 was bored in this.

はない。 The location of the filling layer 17 is originally a space that allows for the displacement of the connecting part 12, but since the filling layer 17 has elasticity in the embodiment described above, this displacement is not hindered, and the elastic material is Instead, it is also possible to use a filled layer with an elastic material interposed therebetween. If the margin is exposed in an open state, there is a risk that the anti-rust material applied to the connecting parts 12 may accidentally enter, but the elastic filling layer 17 prevents the margin from entering. If you fill it with water, you won't have to worry about foreign objects getting in like this.

を取外す。 In order to attach the end portion 23 of the connection member 2 on the connection proceeding side to the attachment portion 13 on the connection proximal end side of the connection component 12, it is convenient to do as follows. Natsu 1
9, the tension rod 25 is inserted into the concave portion 11 through the insertion hole 3 from the end surface 5 on the advancing side of the connection as shown in FIG. A screw connection is made, and a pressing tool 27 such as a hydraulic jack is interposed on the end face 5, and the base end is tightened with a nut 28. Therefore, by operating the pressing tool 27, the connecting member 2
Apply the desired tension to the nut 19 and twist the nut 19 for final installation.
Remove.

部品１２は歪みを生ずるとも充塞層の弾性により
凹陥部１１内の挿通孔３の方向の内壁を押圧する
こはない。 In the connecting block 1 of the present invention, the connecting part 12 is housed in the recessed part 11 in the direction of the insertion hole 3 with the elastic filling layer 17 interposed therebetween. The inner wall of the recessed portion 11 in the direction of the insertion hole 3 is not pressed.

２，２間の強度的弱点を連結部品１２の強度で代
替させることができる。 Since the connecting block 1 of the present invention accommodates the connecting part 12 in the recessed part 11 and has mounting parts 13 and 14 for the connecting member 2 at both ends in the direction of the insertion hole 3, the strength of the connecting part 12 can be increased. For example, the weak point in strength between the connecting members 2 and 2 can be replaced by the strength of the connecting component 12.
本発明の連結方法では連結用部材２は連結部品

ブロツク群は全長に亘り、補強されて構造的信頼
性が向上する。 In the connection method of the present invention, the connection member 2 may be attached to the mounting portions 13 and 14 of the connection component 12, respectively, so that no effort is required for centering the connection members such as in a coupler connection. Since the connecting member 12 is interposed between the connecting members 2 and 2, and the connecting members 2 and 2 are continuous in terms of strength, the connected blocks are reinforced over the entire length and have high structural reliability. improves.

凹陥部１１内に充塞層１７を介在していても弾性
的に緊張されるから、連結による応力を凹陥部１
１に生じさせることはない。 In the connecting method of the present invention, the tension support by the connecting member 2 attached to the attachment parts 13 and 14 of the connecting part 12 is locked to the connecting blocks 1 and 31, so that the connection is achieved, and the connecting member 2 is used to connect the connecting parts. 12 is elastically tensed even if the filling layer 17 is interposed in the concave part 11, so the stress due to the connection is absorbed by the concave part 1.
1 will not occur.
本発明の連結方法では、連結部品１２に対する
連結用部材２の締着に当つても充塞層１７の介在
によつて連結部品１２は凹陥部１１に対して一応
安定しているので作業上便利である。 In the connection method of the present invention, even when the connection member 2 is fastened to the connection part 12, the connection part 12 is stabilized against the recessed part 11 due to the interposition of the filling layer 17, which is convenient for work. be.
さらに述べれば、冒頭掲げた特公昭55−2498号
の発明では連結用ブロツク締付けの圧力を凹陥部
内で受けるためその付近に引張応力が発生すると
いう問題点がある。 More specifically, the invention of Japanese Patent Publication No. 55-2498 mentioned above has the problem that the pressure of tightening the connecting block is received within the concave portion, and tensile stress is generated in the vicinity thereof.
通常は許容応力度内に収まるので差支ないけれ
ども、大型のブロツクではこれを重合連結する連
結用部材が太くなり、緊張力は大きくなるので、
前記のコンクリートの引張応力は許容応力度を超
過することともなる。 Normally, the stress is within the allowable range so there is no problem, but in the case of large blocks, the connecting members that overlap and connect them become thicker, and the tension increases.
The tensile stress of the concrete may exceed the allowable stress level.
殊に、共同溝のような重要構造物や設計重要度
の高い場合は連結部品付近においてもコンクリー
トに引張応力を発生させることなく、逆に圧縮応
力を付加させ得れば好都合である。 Particularly, in the case of important structures such as public ditches or cases of high design importance, it would be advantageous to be able to apply compressive stress to the concrete without generating tensile stress even in the vicinity of connected parts.
前者の大型ブロツクの場合でも後者の共同溝の
ような場合でも、何れの場合においても、重合連
結する連結用ブロツクを一体的に締付けるので、
連結用ブロツク相互間には反力として圧縮応力が
発生し、連結用ブロツク内にも圧縮応力が生じる
ので、凹陥部付近のコンクリートに引張応力発生
の虞れがないのみならず、圧縮応力が発生するこ
とともなる。 In both cases, whether it is a large block in the former case or a common groove in the latter case, the connecting blocks that are overlapped and connected are tightened as one.
Compressive stress is generated between the connecting blocks as a reaction force, and compressive stress is also generated within the connecting blocks, so there is not only no risk of tensile stress occurring in the concrete near the depression, but also compressive stress. It also means doing something.
従つて、冒頭に掲げた特公昭52−17567号や特
公昭55−2498号の発明の使用範囲を拡大するとい
う効果は大きい。 Therefore, the effect of expanding the scope of use of the inventions of Japanese Patent Publication No. 52-17567 and Japanese Patent Publication No. 55-2498 listed at the beginning is significant.
