Based on the structure, the fabricated pavement structure provided by the embodiment adopts the invention concept of 'one hole for two purposes' of arranging the hoisting reserved hole 103 on the thickness surface of the pavement slab 100, so that the traveling crane is not influenced, and the fabricated pavement structure is more attractive. During the hoist and mount, will hoist and mount the piece and install in hoist and mount preformed hole 103, adopt lifting device to place pavement slab 100 in the assigned position, a plurality of pavement slabs 100 hoist and mount the back that targets in place, lay and form the road surface, will hoist and mount the piece and demolish, then adopt the connecting piece to cooperate with hoist and mount preformed hole 103, link together two adjacent pavement slabs 100, can also play the effect of shutoff hoist and mount preformed hole 103 simultaneously, prevent that debris from getting into in hoist and mount preformed hole 103. When the pavement needs to be dismantled, the connecting piece can be dismantled from the hoisting preformed hole 103, then the hoisting piece is installed in the hoisting preformed hole 103, and the pavement slab 100 is hoisted away by adopting hoisting equipment.
In this embodiment, the pavement slab 100 is rectangular, and the thickness surface of the short side 101 of the pavement slab 100 is provided with a hoisting prepared hole 103.
In this embodiment, the pavement slab 100 has two short sides 101 that set up relatively, and every short side 101 sets up two hoist and mount preformed holes 103, and the position that sets up of hoist and mount preformed hole 103 is with the requirement that can satisfy four-point hoist and mount as the standard.
In this embodiment, the number of the connecting members is two, that is, two adjacent road panels 100 are connected by two connecting members. One connection piece is provided on each short side 101 of the road deck 100.
Further, in some optional embodiments, the hoisting prepared hole 103 is a threaded hole, the hoisting member includes a transverse rod 104 and a vertical rod 105, the transverse rod 104 is fixedly connected with the vertical rod 105, the transverse rod 104 is provided with an external thread matched with the threaded hole, the vertical rod 105 is provided with a hoisting hole 119, and the hoisting hole 119 is used for being connected with a hoisting rope 118 of the hoisting device.
Referring to fig. 2, one end of the transverse rod 104 is fixedly connected with one end of the vertical rod 105, and optionally, the transverse rod 104 and the vertical rod 105 are integrally formed. Before hoisting, the transverse bar 104 is screwed into the threaded hole, and during screwing the transverse bar 104 into the threaded hole, a constructor can perform fine adjustment, so that after most of the transverse bar 104 is screwed into the threaded hole, the vertical bar 105 is approximately vertical to the plate surface of the pavement slab 100, and the hoisting hole 119 is positioned above the transverse bar 104. In this way, not only the connection strength between the transverse rod 104 and the road slab 100 can be satisfied, but also the hoisting requirement can be satisfied.
Set the hoist and mount piece to the L type, can avoid adopting the hoist and mount rope 118 that exists when current linear type hoist and mount piece hoists to ensnare the pavement slab 100 easily, cause the problem of pavement slab 100 or hoist and mount rope 118 damage. Meanwhile, the length of the hoisting piece extending out of the short side 101 of the pavement slab 100 can be reduced, so that the hoisting piece is better stressed.

When the pavement slab 100 is hoisted in place, the hoisting member needs to be removed, and in particular, the transverse rod 104 needs to be rotated to separate the transverse rod 104 from the threaded hole. Since the pavement slab 100 is already positioned on the foundation, the vertical rods 105 are also rotated together when the horizontal rods 104 are rotated, and in order to ensure that the vertical rods 105 are smoothly rotated, the length of the vertical rods 105 in this embodiment is not greater than the distance between the centers of the threaded holes and the lower surface of the pavement slab 100, in such a manner that the vertical rods 105 do not contact the foundation when the horizontal rods 104 are rotated.
Optionally, the distance from the center of the threaded hole to the upper surface of the road deck 100 in this embodiment is equal to the distance from the center of the threaded hole to the lower surface of the road deck 100, and the length of the vertical rod 105 in this embodiment is not greater than half the thickness of the road deck 100.
It should be noted that the threaded hole may also be disposed at a position slightly close to the upper surface of the road deck 100, and in this case, the length of the vertical rod 105 may also be slightly greater than half of the thickness of the road deck 100.
Further, in some alternative embodiments, the pavement slab 100 is a concrete pavement slab, an upper layer of reinforcing mesh 106 and a lower layer of reinforcing mesh 107 are arranged inside the concrete pavement slab, a pre-embedded pipe 109 is arranged between the upper layer of reinforcing mesh 106 and the lower layer of reinforcing mesh 107, and the inner wall of the pre-embedded pipe 109 is provided with threads to form a threaded hole.
In this embodiment, referring to fig. 2, a split bar 108 is provided between the upper mesh reinforcement 106 and the lower mesh reinforcement 107 to ensure the space between the upper mesh reinforcement 106 and the lower mesh reinforcement 107.
In this embodiment, the embedded pipes 109 are fixedly connected between the upper-layer reinforcing mesh 106 and the lower-layer reinforcing mesh 107, and the pipe openings of the embedded pipes 109 are located on the thickness surface of the short side 101 of the pavement slab 100.
Further, in certain alternative embodiments, the connection member includes a connection plate 113, a first bolt 111, and a second bolt 112, the connection plate 113 being provided with a first connection hole and a second connection hole; in two adjacent road panels 100, a first bolt 111 passes through the first connecting hole and is connected with the hoisting reserved hole 103 on one road panel 100, and a second bolt 112 passes through the second connecting hole and is connected with the hoisting reserved hole 103 on the other road panel 100.
Referring to fig. 3, after two adjacent road panels 100 are hoisted in place, the thickness surfaces of the long sides 102 of the two adjacent road panels 100 are attached. After the hoisting piece is taken down, the first bolt 111 is inserted through the first connecting hole, the second bolt 112 is inserted through the second connecting hole, then the first bolt 111 is screwed into the hoisting reserved hole 103 on one of the pavement boards 100, and the second bolt 112 is screwed into the hoisting reserved hole 103 on the other pavement board 100.
The connection plate 113 may be made of metal.
Further, in certain alternative embodiments, the long side 102 of the road panel 100 has a length of 4 m.
In this embodiment, the length of the long side 102 of the road deck 100 is the width of the paved road, the width of the road is 4m, it can be ensured that the road deck 100 is only paved along the length direction of the road on a straight road, and the normal traffic of the vehicle can be ensured without paving the road decks 100 side by side in the width direction of the road.
Compared with the prior art, the assembled pavement structure that this embodiment provided, because hoist and mount piece and hoist and mount preformed hole 103 can dismantle the connection, need not to all set up hoist and mount piece on every pavement board 100, also can satisfy the hoist and mount demand, saved the cost. For example, in a paving operation, only two sets of hoisting members are adopted, after one pavement slab 100 is hoisted in place, the hoisting members are removed, then the second pavement slab 100 is hoisted, meanwhile, the hoisting members which are just removed are installed on the third pavement slab 100, after the second pavement slab 100 is hoisted in place, the hoisting members on the second pavement slab 100 are removed, meanwhile, the third pavement slab 100 can be hoisted, and the like until the operation is finished.
