| 161 | DOWEL BAR LOADER | PCT/US2009/058318 | 2009-09-25 | WO2010039595A1 | 2010-04-08 | GUILBAULT, Donny; O'BRIEN, Jack; ZEDLER, Jim |
A dowel bar loader comprising an inlet for receiving dowel bars, an outlet for delivering dowel bars, and a serpentine path connecting the inlet to the outlet. The path includes at least three changes in direction between the inlet and the outlet. In preferred embodiments, the path can include seven changes in direction or more. In one embodiment, the changes in direction comprises an angle change of at least about twenty- five degrees. The dowel bar loader further includes a control mechanism positioned to control movement of dowel bars in the path, and a spacer mechanism for spacing the dowel bars from each other in preparation for delivery to the dowel bar inserter. Preferably, the control mechanism is upstream of the spacer mechanism and spaced from the outlet. In one embodiment, the control mechanism comprises a control wheel that rotates completely around during normal operation. |

Screed rail apparatus comprises a divider plate member and means to support the divider plate member, in use, in an upright position with the upper edge thereof at a predetermined height above the ground, in which the support means comprises legs carrying means for releasable engagement with the laterally-extending elements of the apparatus, whereby the legs are removable therefrom in a lateral direction. The legs are initially attached to or engaged with the laterally-extending elements on one side of the apparatus to enable the height and level of the upper edge with respect to the ground sub-base to be determined while concrete is poured to form a slab on the side of the divider plate remote from the legs. Once the poured concrete has at least partially set, the legs may then be released and removed for reuse and concrete is poured to form the second or subsequent slab. |

Dowels (10, 11, 12) and (13) are V-shaped or U-shaped and bridge a joint (17) between adjacent concrete slabs. Legs (15) and (16) are imbedded in one slab and the apical or bend section (18) up to the juncture line (17) between the slabs may be greased and with an insert (14) in place it results in the apical section being free to move back and forwards in the corresponding slab relatively speaking. The dowel (11) is located inside a sleeve (19) as lost form work in one of the slabs as for the insert (14). The dowel (11) has its apical region (18) in position by reason of stops (20) and (21) inside the sleeve (19). The capacity of the assembly may be supplemented by an additional dowel (11) shown in phantom which is nested inside the first dowel. |

| 164 | DOWEL BAR INSERTER KIT HAVING CHAIN FEEDER | PCT/US2000/026609 | 2000-09-28 | WO01025559A2 | 2001-04-12 | |
| A dowel bar inserter kit (E) is used, typically in combination with a paver (P). The dowel bar inserter kit (E) is removably detachable from the paver (P) and includes at least two laterally extending support beams (S) supported from the paver extending away from and behind the paver (P) over the formed plastic concrete slab (L). A plurality of support carriages (K) move synchronously on each laterally extending support beam (S) towards and away from the supported frame of the paver (P). A suspended dowel bar inserter pan (D) is attached at distal ends to the support carriages, the suspended dowel bar inserter pan (D) defines apertures (42) for insertion of the medial dowel bar insert pan hinge (80) to enable the suspended dowel bar inserter pan (D) to crown with respect to the freshly placed plastic concrete slab (L). An inserter beam (I) is supported at distal ends to the support carriages (K). The inserter beam (I) has dowel bar inserters corresponding to the apertures (42) for the insertion of dowel bars through the suspended dowel bar inserter pan (D). The inserter beam (I) has a medial inserter beam hinge (100) to enable the suspended dowel bar inserter beam to crown with respect to a corresponding crown in the suspended dowel bar inserter pan (D). | ||||||

| The description relates to a dowel fitting device which can be inserted in a slip form paver (1). Several brackets (30) are pivotably arranged in front of the vehicle superstructure (2) and in front of the devices (3, 11, 12) for compacting the concrete (10), in the direction of travel. Dowel receivers (33) are located at the end of the brackets (30). In a loading position (33'), the dowel receivers (33) take dowels (31) from a magazine (32). After a pivoting cycle the dowel receivers assume a setting position in which, looked at in the direction of travel, they extend from the front into the region of initial compacting of the concrete (10) parallel to the direction of travel. The dowels (31) are pushed out at this point. | ||||||

Method for producing a reinforcement for a surface (1). A reinforcement is produced at the site (2) of said surface (1) by laying at least two groups (13,18) of parallel, intersecting reinforcement bars. The reinforcement bars of a group (13) are produced starting from a mobile device (4) by unwinding a piece of wire from a wire store (5), straightening said piece of wire, paying out said piece of wire over the surface (1) in question, and severing it. The invention also relates to a device for achieving this, and to supporting means for bearing reinforcement wires. |

On alimente automatiquement un dispositif pour enfoncer et positionner des goujons (1) dans des dalles de béton (3) lors de la construction d'une route, à l'aide d'un caisson mobile (8) de chargement, cloisonné en compartiments verticaux (9), sans fond, qu'on entraîne d'un côté à l'autre de la plaque lisseuse (4). Les goujons (1) tombent du caisson (8) dans des entailles (15) d'un cadre-tiroir (12). En actionnant le cadre-tiroir (12), on déplace chacun des goujons emprisonnés dans les entailles (15) vers des ouvertures d'introduction des goujons au travers de la plaque lisseuse (4), par lesquelles les goujons tombent sur la surface de la dalle de béton (3). |
