本発明は舗装版相互を結合する結合構造に係わり、特に
プレキャストコンクリート舗装版相互を結合鉄筋を介し
て結合するコンクリート舗装版の結合構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a connecting structure for connecting paving slabs to each other, and particularly to a connecting structure for concrete paving slabs for connecting precast concrete pavement slabs to each other via connecting reinforcing bars.
［技術的背景とその同題点］

クリート舗装版を敷設して道路等の舗装面を形成する場
合、舗装版相互を連結する必要があり、その種々の方法
が提案されている。[Technical background and the same topic] When forming a paved surface such as a road by laying precast concrete pavement slabs manufactured in advance at a factory or on site, it is necessary to connect the pavement slabs to each other, and there are various methods for doing so. Proposed.
この一手段として、一方の舗装版には一端が舗装版の端

所に隙間が生ずる。そして充填材を充填する際には前記
１ｌＩｌｉｌｉＪから充填材が漏れてしまうことが懸念
される。One way to do this is to drill a horizontal hole in one of the paving slabs, one end of which opens into the end surface of the paving slab, insert the bonding reinforcing bars into this horizontal hole, and connect the end surface of the horizontal hole and the top surface of the paving slab with a through hole. Drill a horizontal hole that communicates with the end face of the other FJI plate, and then drill the holes so that the openings of both horizontal holes coincide.
It is known to push the bonding reinforcing bars into the horizontal hole on the other side and then fill the horizontal hole with filler material. In such a method, it is necessary to make the diameter of the joint reinforcing bar smaller than the diameter of the horizontal hole, so a gap is created at the opening after the joining reinforcing bar is pushed in. When filling with the filler, there is a concern that the filler may leak from the 1lIliliJ.
これは第４図に示す特開昭５８−７００３号公報の舗装

圧縮空気によって押し込み、次いで充填材６を充填する
際、水平孔２．５の内壁と結合鉄筋３間のＷ４闇を通っ
て充填材６が外部に漏れてしまうというものである。This method is similar to the paving slab joining method disclosed in Japanese Patent Application Laid-Open No. 58-7003 shown in FIG. A horizontal hole 5 is provided in the other paving slab 4, the openings of both horizontal holes 2°5 are aligned, the joint reinforcing bars 3 are pushed in with wire or compressed air, and then the filling material 6 is filled. The filling material 6 leaks to the outside through the W4 gap between the inner wall of the horizontal hole 2.5 and the joint reinforcing bar 3.
この漏れをなくサ一手段としては結合鉄筋を水平孔の内
径と同一とすることが考えられるが、このように同一径
とすると両水平孔の開口を一致するように舗装版を合わ
せる際、正確さが必要となり、その結果敷設作業効率が
著しく低下する問題が生ずる。One way to eliminate this leakage is to make the connecting reinforcing bars the same diameter as the horizontal holes, but if you make them the same diameter, it will be difficult to accurately align the paving slabs so that the openings of both horizontal holes match. As a result, the problem arises that the efficiency of the installation work is significantly reduced.

12 joint end surfaces 13 and 14 are placed in abutting state. An elastic airtight backing 15 made of foamed rubber or the like is fitted between the joint end surfaces 13 and 14. A horizontal hole 16 is formed in one of the paving slabs 12 by a pipe, and one end thereof opens to the joint end surface 13, and a joint reinforcing bar 11 is slidably and loosely fitted into the horizontal hole 16. At the rear end of this joint reinforcing bar 17, a slidable backing 18 having elasticity such as foamed rubber is provided. Further, vertical holes 19 and 20 having a circular cross section and communicating with the upper surface of the paving slab 11 are provided in the deep and central portions of the horizontal hole 16, respectively.

れる。The other paving slab 12 has one end connected to the joint end surface 14 by a pipe.
A horizontal hole 21 is formed which opens into the horizontal hole 21 . This horizontal hole 21 has a diameter slightly larger than the horizontal hole 16 provided in the paving slab 11, so that the connecting reinforcing bar 17 can be easily inserted. The length of the horizontal hole 21 is approximately half that of the horizontal hole 16,
Approximately half of the joint reinforcing bars 17 are accommodated within this horizontal hole 21. Furthermore, vertical holes 22 and 23 each having a circular cross section and communicating with the upper surface of the paving slab 12 are located at the back and front sides of the horizontal hole 21.
will be established. When the horizontal holes 16 and 21 abut each of the joining end surfaces 13 and 14 at a predetermined position, the openings of the horizontal holes 16 and 21 coincide with each other with the airtight backing 15 interposed therebetween;
Pavement slabs 11 and 12 are laid so that their axes are the same.

into the horizontal hole 21 provided in the. And bonded iron M17
The vertical hole 22 confirms that the
Stop the compressed air A visually. Next, as shown in FIG. 3, a filler 24 such as quick-setting cement or mortar is filled into the vertical hole 19.22 while visually checking the filling state through the vertical hole 20.23. Horizontal hole 16 is filled with horizontal hole 1
Filler 2 is placed in the space surrounded by 6 and backing 18.
In the other horizontal hole 21, the space surrounded by the horizontal hole 21 and the airtight backing 15 is filled with a filler 25. At this time, it is possible to prevent the filler 25 from leaking to the outside from the joint end surface 14 side, and the air in the horizontal holes 16.21 is discharged to the outside through the vertical holes 20.23. By curing the filler 24 in this way, the paving plate 11.1
2 are firmly connected by connecting reinforcing bars 17.
尚、２５は舗装版１１．１２の補強鉄筋であり、又実施

．． After bonding of 12, the paving slab 11.
When 12 contracts and expands, the backing 15 compensates for the change.
Absorbed by the deformation of,! ! It is possible to prevent deformation and movement of the paving slabs 11 and 12 due to degree changes. Moreover, by providing the backing 18 at the rear end of the joint reinforcing bar 17, the horizontal hole 16
The interior on the end face 13 side is partitioned off by the backing 18, which eliminates air leakage when compressed air A is fed, and also prevents leakage of the filler 25. Further, after the paving plates 11.12 are bonded by this backing 18, the paving plates 11.12 shrink due to temperature changes.

a, 22a are circular, and as a result, the area is smaller than that of the elliptical opening, and peeling and damage to the filler 24 can be reduced.Furthermore, the center of the horizontal hole 1B communicates with the top surface of the plate 12. Vertical hole 20. and ttJl of horizontal hole 21
The front vertical hole 23 that communicates with the upper surface of the pavement slab 12 allows the movement and installation of the joint reinforcing bars 17 to be confirmed, and also serves as an air filter when filling with the filler material 24.
Enables smooth operation.
