The function of recycling can not need to restore place after solving the problems, such as conventional cast-in-place pavement construction according to function.
2, provided by the present invention for the U-shaped detachable dowel bar structure of prefabricated heavy mail road deck, it is ensured that heavy vehicle
It will not cause the faulting of slab ends of seam crossing when passing through road deck, the pulling force between panel and shearing are effectively transmitted by transmission rod.
Description of the drawings
Fig. 1 is the U-shaped detachable dowel bar structure for prefabricated heavy mail road deck for meeting the preferred embodiment of the present invention
Schematic diagram.
Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1, the U-shaped detachable transmission rod knot for prefabricated heavy mail road deck that one embodiment of the invention provides
Structure includes:Special-shaped casing 2 and U-shaped transmission rod 3.Special-shaped casing 2 is embedded in prefabricated heavy mail road deck 1, from prefabricated heavy mail road surface
One of plate 1 face is through to another adjacent face, pre-buried special-shaped casing in adjacent two prefabricated heavy mail road decks 1
2 be spliced into it is U-shaped.U-shaped transmission rod 3 is spliced into U-shaped with special-shaped casing 2 pre-buried in adjacent two prefabricated heavy mail road decks 1
Match, U-shaped transmission rod 3 runs through special-shaped casing 2 pre-buried in two adjacent prefabricated heavy mail road decks 1.
Special-shaped casing 2 is through to the one side of prefabricated heavy mail road deck 1 from the top surface of prefabricated heavy mail road deck 1, adjacent
It is aligned through the side for having special-shaped casing on two prefabricated heavy mail road decks 1.
The service sleeve 2 in 1 process of road deck, seam crossing ozzle height are 1/2 plate thickness, and other end ozzle opening is perpendicular
It is straight upward.Construction site is transported to after 1 completion of processing of road deck, is then mated formation by crane.It should make as possible in process of deployment
Casing 2 in adjacent two block roads plate 1 is aligned, since cross section of the service sleeve 2 on side is the slotted hole of horizontal direction,
Certain deviation in place can be allowed in the horizontal direction.After the completion of in place, transmission rod 3 is inserted into from ozzle straight up, directly
