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 1 is formed in the block body 1'.
1, since the insertion hole 3 passes through the corner 6, the insertion hole 3 is cut at the corner 6, and the insertion holes 3, 3 are opened at both ends 29, 30 of both recesses. The recess 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.

穿設した例を示す。 The connecting part 12 accommodated here has attachment parts 13, 1 for the connecting members 2, 2 at both ends in the direction of the insertion hole 3.
4 is provided, and through holes 15 and 16 as attachment means for the connecting members 2 and 2 are bored in the attachment portions 13 and 14, respectively.

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 It is possible to have a margin within the concave portion 11 that allows for the displacement. As will be described later, this margin is a space for avoiding pressure contact between the connecting part 12 and the concave part 11 due to relative displacement of the connecting part 12 with respect to the concave part 11.
This provides a margin for the connecting portion 12 including the connecting portion 14 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.

い。 5 to 13 show three 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 made of elastic material 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, the anchor plate 21 was further interposed and the nuts were tightened, and the grout injection hole 20 was bored in this. 11th, 12th,
In the third example of FIG. 13, in the second example, the filling layer 1
7. It is shown that the concave portion 11 is formed using the connecting part 12 as an inner mold. Edge cutting layers 22 made of oil, paper, etc. are shown on both sides and the bottom of these. Under normal loads, the deformation is considered to be within the range of distortion of the connecting part 12, but if we consider that a large load may occur even locally, the connecting part 12 will be moved against the recessed part 11 with the edge layer 22 interposed. It is preferable that the relative displacement be performed.
充填層１７の個所は元来空間で連結部品１２が
変位し得る余裕であるが、充填層１７は弾褥性を

連結部品１２内に施す防錆材料などが誤つて入る
などの虞れなしとしないので弾褥性のある充填層
１７で該余裕を充塞して置けばこのような異物が
入る心配はない。 The location of the filling layer 17 is originally a space that allows for the displacement of the connecting component 12, but since the filling layer 17 has elasticity, this displacement is not hindered, and the filling layer 1
It is also conceivable to interpose an elastic material instead of 7. 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, so the margin is filled with a resilient filling layer 17. If you leave it there, you won't have to worry about foreign objects like this getting in.

ることはない。 In the connection method of the present invention as set forth in claim 2, the tension support by the connection member 2 attached to the attachment portions 13 and 14 of the connection component 12 is performed in accordance with the connection method of the present invention as set forth in claim 1. The connection is achieved by being locked to the block 1, and the connection member 2 tensions the connection part 12 so that it can be displaced into the recess 11, so that stress due to connection is not generated in the recess 11.
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
内で受けるために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 thus 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

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 connected by polymerization are tightened together, so compressive stress is generated as a reaction force between the connecting blocks. As a result, compressive stress is also generated within the connecting block 1, so not only is there no risk of tensile stress occurring in the concrete near the recess, but compressive stress will also occur.
