Description

[Detailed Description of the Invention] When connecting box culverts, retaining walls, etc. in an overlapping manner, they may be connected in one piece with a connecting member such as a steel rod pushed through in the direction of the connection, but the present invention Hakobi) J: This is a 1/11 proposal for improving the eel connecting blocks and their connecting method.

An example in which the present invention is implemented in a box culvert will be described. The connecting block is made of Funkley-1 or other hardened and molded material, and is made of steel rod.

Steel strip top 1. An insertion hole 3 through which a connecting piece 2 made of a wire strand or the like is inserted is inserted between both end faces 4.5 at a corner (t'j facing i).The surface of the sponge rubber is coated with vulcanized rubber. Backing 7 for 11th
Or puff. 1-ng7. j: Riha rIJ! This indicates that an elastic piece 8 made of an elastic material that limits the amount of compression of the backing 7 is appropriately attached to the end surface by 4.5G.

The following 1- is the same for the ordinary connecting block 31 in FIG. 2, but in the connecting block l of the present invention, the block If the recessed portion 11 is cut out in the body 1', the insertion hole 3 passes through the corner 6, so the insertion hole 3 is cut at the corner 6, and the insertion holes 3, 3 are opened directly at both ends. The recessed portion 11 may be formed by forming a recess in the block 1, or may be formed by embedding a box made of a thin plate. The connecting part 12 housed here is provided with attachment parts 13 and 14 for the connecting member 2.2 at both ends in the direction of the insertion hole 3. The connecting members 2, 2 are attached using the through holes 15 as a means.
, 16 is shown below. The connecting parts are connecting members 2
It is intended to reinforce the connecting block 1 in place of the member 2 in places where the member 2 is not present, and it can also be considered to fill the absence of the member 2 and become connected to the member 2 to exert fastening strength. Therefore, considering these loads, steel materials,
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.

5 to 13 show three examples of the interior of the recessed portion 11. The connecting part 12 is box-shaped, and a filling layer 1 having elasticity such as natural rubber or urethane rubber is placed between the mounting parts 13 and 14 and the recessed part 1.
7, and tighten the nut 9 with a washer 18 interposed. In the first example, the connecting part 12 is inserted into the recess 11 with or without adhesion of the filling layer 17, and the filling layer 17 is provided with a grout injection hole 20 to block water from entering into the recess I. did. In the second example, a nut was further tightened with an anchor plate 21 interposed therebetween, and a grout injection hole 20 was bored therein. The third example shows that the concave portion 11 was molded using the filling layer +7 and the connecting component 12 as the inner mold in the second example. A cutting layer 22 made of oiled paper or the like is shown on both sides and the bottom of the straw. Under normal loads, the deformation is considered to be within the range of distortion of the connecting part 12, but the existence of the edge layer 22 is advantageous, and regardless of whether a large load occurs even locally, the deformation is It is preferable that the gap between the connecting component 12 and the concave portion 11 be filled by the bulging property.

The connection blocks of the first invention have been described above, and now the connection method of the second invention will be described.

As shown in FIG. 4, a normal connecting block 31. -- is superimposed and connected from the connection proximal end side indicated by arrow A to the connection proceeding side, and the connecting block l of the present invention is placed at least at the connection proceeding side end, but in the figure, it is also connected to the connection proximal end. It shows that the block 1 is placed and fastened to the foundation structure (not shown) with the foundation connection member 2'. The end 23 on the connection proceeding side of the connection member 2 which is inserted into the insertion hole 3 of the connection blocks 1, 31.1 which are superimposed and connected here and fastens the connection blocks 1, '31, 1 of the first group. is attached to the attachment portion 13 on the connection proximal end side of the connection component 12,
Furthermore, a connecting member 31. . . . is fastened to the attachment portion 14 of the connection component 12 on the connection proceeding side with another connection member 2 having the end 24 of the connection member 2 on the connection proximal end side attached thereto.

In the illustration, the connecting block 1 of the present invention is also placed at the end of the second group of connecting members on the connecting advancing side, but by doing so, the connecting method of the present invention can be repeated to make the connecting block 1. The installation line can be made longer.

The connection member 2 is attached to the attachment portion 13 on the connection proximal end side of the connection component 12.
For attaching the leading end 23 of the connection, it is convenient to proceed as follows. After temporarily installing it with nut 19,
As shown in FIG. 14, the tension rod 25 is inserted into the recessed part 11 from the end 5 on the connection proceeding side through the insertion hole 3, and is threadedly connected to the end 23 via the connector 26. The proximal end is tightened with a nut 28 using a pressing tool 27 such as a hydraulic jack. Therefore, the pressing tool 27 is operated to apply a desired tension to the connecting member 2.

19 for final installation, and then attach the suppressor 27. Consolidated 1,260
゜Remove the tension rod 25.

FIG. 15 shows the fully installed state, and the dotted line indicates that the connecting block is superimposed and connected to the next position on the connecting progress side.

The connecting block l of the present invention has a connecting part 12 in a concave portion 11.
and connecting members 2 at both ends in the direction of the insertion hole 3.
Since the mounting parts 13 and 14 are provided, the connecting members 2 and 2
The strength weakness between the connecting parts 12 can be compensated for by the strength of the connecting part 12.

In the connecting method of the present invention, since the connecting member 2 only needs to be attached to the mounting portions 13 and 14 of the connecting component I2, it is not necessary to align the connecting members as in the case of connecting a series of couplers. Since the connecting part 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 a high structural reliability. will improve.

The present invention is highly advantageous for use in open waterways, conduits, and other connecting blocks and methods of connecting the same.
