次に、前記舗装版の設置方法について説明する。尚、設置における結合作業に係る説明は後述する。 Next, the installation method of the pavement plate will be described. In addition, the description regarding the joint work in installation is mentioned later.

まず、既設舗装をコンクリートカッター,ブレーカーなどを用いて取り壊した後、搬出する。次に、図6及び図7に示すように、既設路盤上に補足材を搬入して敷き均し、また、振動ローラ等により転圧すると共にレベル等を調節する。このようにして路盤15を形成した後、該路盤15の上部を構成するアスファルト中間層14を形成し、該アスファルト中間層14に後述するグラウトの浸透防止と充填促進のために厚さが0.1〜0.3mm程度のビニール製等の樹脂シート16を敷設し、その上に前記受け孔9に対応して高さ調整ボルト11の受け板17となる鉄板等を適所に配置する。尚、アスファルト中間層14は必ずしも設ける必要はないが、隣合う舗装版1,2の目地部からの雨水侵入と振動とによる調整砂の流出によって目地部下方が空洞化することを防止すると共に、支持力増強を図る面から、アスファルト中間層14を設けることが好ましい。 First, the existing pavement is demolished using a concrete cutter, breaker, etc., and then removed. Next, as shown in FIGS. 6 and 7, the supplementary material is carried on the existing roadbed and spread, and the level is adjusted by rolling with a vibrating roller or the like. After the roadbed 15 is formed in this manner, an asphalt intermediate layer 14 constituting the upper portion of the roadbed 15 is formed, and the thickness of the asphalt intermediate layer 14 is reduced to 0. A resin sheet 16 made of vinyl or the like having a thickness of about 1 to 0.3 mm is laid, and an iron plate or the like that becomes the receiving plate 17 of the height adjusting bolt 11 is disposed in a proper position on the resin sheet 16. Although it is not always necessary to provide the asphalt intermediate layer 14, while preventing the bottom of the joint from being hollowed out by adjusting sand flowing out from the joint of the pavement plates 1 and 2 adjacent to each other and vibration, It is preferable to provide the asphalt intermediate layer 14 from the standpoint of enhancing the supporting force.

次に、受け孔9の雌螺子体10に吊り上げ具(図示せず)を螺着して運搬トラック及びクレーンにより舗装版1,2を所定位置に敷設する。そして、吊り上げ具を外し、図6に示すように、前記受け孔9の一側から高さ調整ボルト11を螺入して該高さ調整ボルト11の下端を受け板17に当接せしめてレベルの調節をし、所定高さに支持する。また、隣合う舗装版1,2の接合端面23,24間に挟むようにパッキン材30を配置する。 Next, a lifting tool (not shown) is screwed onto the female screw body 10 of the receiving hole 9, and the paving plates 1 and 2 are laid at a predetermined position by a transport truck and a crane. Then, the lifting tool is removed, and as shown in FIG. 6, the height adjustment bolt 11 is screwed from one side of the receiving hole 9 and the lower end of the height adjustment bolt 11 is brought into contact with the receiving plate 17 to make a level. And adjust to a predetermined height. Further, the packing material 30 is disposed so as to be sandwiched between the joining end faces 23 and 24 of the adjacent paving plates 1 and 2.

この後、前記グラウト孔12より自然流下させて舗装版1,2の裏側に裏込め用のグラウト材18を充填し、硬化させる(図7)。グラウト材18が硬化した後、ボルト11を引き抜き、これによりボルト11を引き抜いた箇所が空洞となり、図8に示すように、受け孔9の上部にキャップ11Bを装着し、この後、その受け孔9の上部に超速硬性のモルタル19を充填し、また、グラウト孔12の上部にも超速硬性のモルタル20を充填する。尚、ボルト11を引き抜いた後、図9に示すように、受け孔9に、合成樹脂製の仮充填部材11Aを螺入し、受け孔9の上部にキャップ11Bを装着し、該仮充填部材11Aにより受け孔9を保護するようにしてもよい。 Thereafter, the grouting material 18 is filled with a back filling grout material 18 on the back side of the pavement plates 1 and 2 through the grouting hole 12 (FIG. 7). After the grout material 18 is hardened, the bolt 11 is pulled out, whereby the portion where the bolt 11 is pulled out becomes a cavity, and a cap 11B is mounted on the upper portion of the receiving hole 9 as shown in FIG. 9 is filled with a super fast-hardening mortar 19 and the grout hole 12 is also filled with a super-fast hardening mortar 20 . After the bolt 11 is pulled out, as shown in FIG. 9, a temporary filling member 11A made of synthetic resin is screwed into the receiving hole 9, and a cap 11B is attached to the upper part of the receiving hole 9, and the temporary filling member The receiving hole 9 may be protected by 11A.

次に、上述した設置作業中に行う隣合う舗装版1,2の結合作業について説明する。硬質材料からなる結合鉄筋26の他端側に、粘着テープ33により、ビニールテープ32の他端を接着して連結する。隣の舗装版を敷設する前に、その結合鉄筋26を他端から水平孔25に挿入して収める。 Next, the joining operation | work of the adjacent pavement plates 1 and 2 performed during the installation operation mentioned above is demonstrated. The other end of the vinyl tape 32 is bonded and connected to the other end of the bonded reinforcing bar 26 made of a hard material with an adhesive tape 33. Before laying the adjacent pavement plate, the connecting reinforcing bar 26 is inserted into the horizontal hole 25 from the other end and stored.

表側舗装面7を用いる場合、隣合う水平孔25,25の一方のみに結合鉄筋26を挿入する。具体的には、図1では、図中下側の結合端面23の左側の水平孔25と、図中右側の結合端面23の上側の水平孔25に結合鉄筋26を挿入する。 When the front side pavement surface 7 is used, the coupling reinforcing bars 26 are inserted into only one of the adjacent horizontal holes 25 and 25. Specifically, in FIG. 1, the coupling rebar 26 is inserted into the horizontal hole 25 on the left side of the lower coupling end surface 23 in the drawing and the horizontal hole 25 on the upper side of the coupling end surface 23 on the right side in the drawing.

また、ビニールテープ32の一端は舗装版1の上に引き出しておく。好ましくは、ビニールテープ32の途中は、水平孔25上の結合端面23に沿わせ、さらに、舗装版1の上面に沿わせておく。この状態で、上述したようにパッキン材30を接合端面3,4間に挟んで、舗装版1,2を敷設し、ビニールテープ32の一端は、外部である舗装版1,2の表面側の上に引き出しておく。 One end of the vinyl tape 32 is drawn on the paving plate 1. Preferably, the middle of the vinyl tape 32 is along the coupling end surface 23 on the horizontal hole 25 and further along the upper surface of the paving plate 1. In this state, across the packing material 30 as described above between the joining end face 2 3, 2 4, laying pavement 1,2, one end of the plastic tape 32, the surface of the pavement 1,2 which is an external Pull it out on the side.

次に、ビニールテープ32の一端側を外側に引っ張ると、接合鉄筋26が他方の舗装版2側に送られ、挿通孔31から水平孔28内に挿入され、結合鉄筋26の一端が、水平孔28の奥に当ることにより止まる。この場合、結合鉄筋26が水平孔28の奥に当接する際に発する音により、これを確認できる。この後、さらにビニールテープ32を強く引けば、粘着テープ33からビニールテープ32が外れ、ビニールテープ32を抜き取ることができる。尚、ビニールテープ32が舗装版1内に残っても問題はない。 Next, when one end side of the vinyl tape 32 is pulled outward, the joining rebar 26 is sent to the other pavement plate 2 side and inserted into the horizontal hole 28 from the insertion hole 31, and one end of the connecting rebar 26 is connected to the horizontal hole. Stop by hitting the back of 28. In this case, this can be confirmed by the sound generated when the connecting reinforcing bar 26 comes into contact with the back of the horizontal hole 28. Thereafter, if the vinyl tape 32 is further pulled strongly, the vinyl tape 32 is detached from the adhesive tape 33 and the vinyl tape 32 can be extracted. There is no problem even if the vinyl tape 32 remains in the pavement plate 1.

この後、表側に開口する垂直孔27,29から充填材34を充填し、水平孔25,28と結合鉄筋26との隙間及び垂直孔27,29を充填材34により埋める。尚、充填材34には硬化性を有するグラウト材などが用いられる。 After that, the filler 34 is filled from the vertical holes 27 and 29 opened on the front side, and the gaps between the horizontal holes 25 and 28 and the connecting reinforcing bars 26 and the vertical holes 27 and 29 are filled with the filler 34.

一方、舗装版1,2の表側舗装面7が轍などによって磨耗したような場合には、パッキン材0を除去し、隣合う舗装版1,2間の結合鉄筋26をカッターなどにより切断する。この場合、充填材34を充填した垂直孔27,29を目印にして結合鉄筋26の位置を確認できる。また、前記受け孔9のモルタル19を除去し、キャップ11Bを取り出すと、上述したようにボルト11を外してできた中空状の雌螺子体10が表れ、或いは、仮充填部材11Aを用いた場合は、仮充填部材11Aも取り外し、吊り具(図示せず)を前記受け孔9の雌螺子体10に螺合し、雌螺子体10に螺合した吊り具と前記吊り具41を用いて舗装版1,2を吊り上げた後、反転し、裏側舗装面8を表面とし、上述したように路盤工を行い、さらに、裏側舗装面8側から受け孔9にボルト11を螺入してレベルなどを調節する。 On the other hand, when the front side pavement surface 7 of the pavement plates 1 and 2 is worn by wrinkles or the like, the packing material 30 is removed, and the joint reinforcing bars 26 between the adjacent pavement plates 1 and 2 are cut with a cutter or the like. . In this case, the position of the joint reinforcing bar 26 can be confirmed using the vertical holes 27 and 29 filled with the filler 34 as marks. Further, when the mortar 19 of the receiving hole 9 is removed and the cap 11B is taken out, the hollow female screw body 10 formed by removing the bolt 11 as described above appears, or when the temporary filling member 11A is used 11A also removes the temporary filling member 11, screws a hanger (not shown) into the female screw body 10 of the receiving hole 9, and pavers using the hanger and the hanger 41 that are screwed into the female screw body 10. After the plates 1 and 2 are lifted, they are reversed, the back side pavement surface 8 is used as the surface, the roadbed work is performed as described above, and the bolts 11 are screwed into the receiving holes 9 from the back side pavement surface 8 side to level, etc. Adjust.

また、反転する前に、グラウト孔12からモルタル20を除去し、或いはモルタル20をパイプ13と共に除去する。さらに、隣に舗装版2を敷設する前に、表側で使用しなかった隣合う水平孔25,25の他方のみに結合鉄筋26を挿入し、また、ビニールテープ32の一端は舗装版1の上である裏側舗装面8に引き出しておく。そして、表側舗装面7を上にする設置方法と同様にして隣に舗装版2を敷設する。 Further, before the inversion, the mortar 20 is removed from the grout hole 12 or the mortar 20 is removed together with the pipe 13. Further, before laying the pavement plate 2 next to each other, the reinforcing bars 26 are inserted only into the other of the adjacent horizontal holes 25 and 25 that are not used on the front side, and one end of the vinyl tape 32 is placed on the pavement plate 1. It is pulled out to the back side pavement surface 8. Then, the paving slab 2 is laid next to the installation method with the front side pavement surface 7 facing upward.

レベルを調節した後、グラウト孔12から下向きとなった舗装面7側にグラウト材18を充填し、固化させる。また、ボルト11を抜き出した後、受け孔9及びグラウト孔12の上部に超速硬性のモルタル19,20を充填する。 After adjusting the level, the grout material 18 is filled on the side of the pavement surface 7 facing downward from the grout hole 12 and solidified. Further, after extracting the bolt 11, super-hard mortars 19 and 20 are filled in the upper portions of the receiving hole 9 and the grout hole 12.

また、ビニールテープ32の一端側を外側に引っ張ると、接合鉄筋26が他方の舗装版2側に送られ、挿通孔31から水平孔28内に挿入され、結合鉄筋26の一端が、水平孔28の奥に当ることにより止まる。この後、上になった裏側舗装面8に開口する垂直孔27,29から充填材34を充填し、水平孔25,28と結合鉄筋26との隙間及び垂直孔27,29を充填材34により埋める。尚、充填材34には硬化性を有するグラウト材などが用いられる。 Further, when one end side of the vinyl tape 32 is pulled outward, the joining rebar 26 is sent to the other pavement plate 2 side and inserted into the horizontal hole 28 from the insertion hole 31, and one end of the connecting rebar 26 is connected to the horizontal hole 28.
