As shown in Figures 1 to 5, which may include mainly：Polylith precast slab 11
(can abbreviation prefabricated board) and a plurality of precast concrete beam 12 (can abbreviation precast beam).Wherein, precast concrete beam 12 bridges
In the both sides (Fig. 1 only shows side) of at least two pieces precast slabs 11 of continuous laying, the precast concrete beam 12 will
At least two concrete slabs 11 of continuous laying are fixedly connected, to form the overall structure layer of bearing load.
It is connected across on two pieces of prefabricated boards in one piece of precast beam it should be noted that, although Fig. 1 and Fig. 6 are illustrated only, but this
Field technology personnel are appreciated that one piece of precast beam can also be connected across on more than two pieces prefabricated boards, specifically can be according to prefabricated
The length and width of beam, length of prefabricated board etc. are configured.Also, installation site of the precast beam in prefabricated board both sides can be right
Claim, it can also be asymmetric.In addition, if construction area is longer road surface, airfield runway etc., along the length of construction area
It can be with the multigroup precast beam of continuous laying and prefabricated section, in the position of every two pieces of prefabricated boards linking, preferably by one group of precast beam
Bridging, with ensure assemble after road surface or airfield pavement it is smooth.
As shown in Figure 3 and Figure 4, in one possible implementation, the both sides of the precast slab 11 are set respectively
It is equipped with step structure 110, the precast concrete beam 12 bridges the upper surface of the step structure 110.
In one possible implementation, at least two are embedded in the step structure 110 of the precast slab 11
Root fixed link 111.
Wherein, the quantity of pre-buried fixed link 111 can be set according to the length of prefabricated board in the step structure 110 of prefabricated board
It sets, in general, pre-buried at least two fixed links 111 in the side step structure 110 of each prefabricated board, a prefabricated board in Fig. 1
Pre-buried 6 fixed links 111 in side.It is understood that the quantity of above-mentioned fixed link 111 is only a kind of example and unrestricted,
It can flexibly be selected according to the length of prefabricated board and the endurance of precast beam.As shown in figure 5, fixed link 111 is preferably but unlimited
In the screw rod or bolt etc. that are embedded in prefabricated board.
As shown in Figure 3, it is preferred that the height H1 that the fixed link 111 is exposed from the upper surface of the step structure 110 is small
Height H2 in or equal to from the upper surface of the step structure 110 to the upper surface of the precast slab 11.This
Sample avoids fixed link from being higher by the structure sheaf after assembly, causes traffic safety hidden danger.
As shown in Figure 1, in one possible implementation, being provided in the step structure 110 for lifting and filling
The built-in fitting 113 of slurry.Hole for hoist can be reserved on prefabricated board after setting built-in fitting 113 and is used for mounting hanger, and lifting appliance can
It is installed with being sling precast slab 11 by suspender.In addition, suspender is taken out from built-in fitting, it is pre- in prefabricated board
It boxes out and is combined with the mounting hole in precast beam, the operations such as subsequent grouting can be carried out.The process specifically lifted may refer to down
State the associated description of embodiment of the method.
Embodiment two
Fig. 7 is the schematic diagram of the fixed form of the prefabrication and assembly construction concrete of the embodiment of the present invention two.In embodiment
On the basis of one, as shown in Fig. 7, Fig. 5 and Fig. 1, the prefabrication and assembly construction concrete of the present embodiment, the precast concrete beam
Through-hole corresponding with 111 position of the fixed link 122 is provided in 12.For example, fixed link 111 is bolt or screw rod, Ke Yi
It is reserved and the matched bolt hole of fixed link in precast beam.
In one possible implementation, as shown in Figure 1 and Figure 5, the fixed link 111 passes through corresponding through-hole 122
The precast concrete beam 12 is fixed on the step structure 110.
In one possible implementation, as shown in fig. 7, being located at the through-hole in the precast concrete beam 12
122 top has fixing groove 123, gasket 124 is equipped in the fixing groove 123, and pass through nut 31 and the gasket
124 are fixed on the precast concrete beam 12 on the step structure 110.The advantages of this fixed form be avoid it is prefabricated
The case where plate caused by deviation and beam can not be installed and the height difference between contiguous prefabricated plate is conveniently adjusted to ensure structure sheaf
Flatness.
In addition, as shown in figure 5, grout hole 127 and suspension centre 128 can also be reserved in precast beam.Wherein, it is assembling process
In, lifting appliance can be sling precast beam in 128 position of suspension centre at precast beam both ends.And in precast beam and prefabricated board dress
After leveling, it can be poured between precast beam and prefabricated board and prefabrication and assembly construction concrete structure from grout hole 127 by grouting material
Gap between layer and base.
Embodiment three
Fig. 8 is the flow chart of the assembly method of the prefabrication and assembly construction concrete of the embodiment of the present invention three.Such as Fig. 8 institutes
Show, for the prefabrication and assembly construction concrete of any one structure in above-described embodiment, assembly method may include：
Step 801, the designated position being lifted into polylith precast slab in construction area；
Step 802, the top that a plurality of precast concrete beam is lifted by crane to the polylith precast slab, will be described a plurality of pre-
Beams of concrete processed is placed into the both sides of the polylith precast slab；
Step 803, will the precast slab and the precast concrete beam leveling and after fixing, dismounting is described prefabricated
On the step structure of concrete slab and the suspender in the precast concrete beam；
Step 804 is in the milk by suspender installation duct.
Specifically, concentration pre-casting concrete slab and beams of concrete first outside construction area.It is strong to reach design by health
After degree, prefabricated board and transporting precast beams are lain against prefabricated board by corresponding lifting appliance referring to Fig. 6 to construction site
In the base of leveling, adjust prefabricated Board position adjacent two pieces of prefabricated boards are carried out it is just flat, then to contiguous prefabricated plate seam crossing into
Row essence is flat, precast beam is placed on step structure after the completion of the flat work of essence, and make the spiral shell on the screw rod and precast beam on prefabricated board
Hole corresponds, and then by the connection of nut and screw rod, the contiguous prefabricated plate after leveling is fixed together.Finally by pre-
Grouting material is poured into the gap between prefabrication and assembly construction concrete and base by the grout hole stayed.It can be according to the strong of grouting material
Degree requires to determine the time of open to traffic.
The present invention and the comparison on common prefabrication and assembly construction road surface have the following advantages that：
The linking of common prefabricated assembly structural layer is that the transmission rod of seam crossing or ribbet is leaned on to be attached, structure sheaf
Difficulty of construction is big, globality is poor, not can solve surface evenness problem.The prefabrication and assembly construction being laid with using the present invention
Formula structure sheaf is directed to this defect of common prefabricated construction layer, fixes the prefabricated board after leveling by precast beam, makes dress
Structure sheaf after matching has higher flatness；And by pour into grouting material fill prefabrication and assembly construction concrete and base it
Between gap, ensure that the globality and bearing capacity of structure.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
