Being taken out from built-in fitting by suspender, the installing hole in precast beam of the preformed hole in precoated plate is combined, permissible
Carry out the operations such as follow-up grouting.The process of concrete lifting may refer to the relevant of following embodiment of the method and retouches
State.
Embodiment two
Fig. 7 is the signal of the fixed form of the prefabrication and assembly construction concrete of this utility model embodiment two
Figure.On the basis of embodiment one, as shown in Fig. 7, Fig. 5 and Fig. 1, the prefabrication and assembly construction of the present embodiment mixes
Xtah Crude Clay structure layer, is provided with lead to corresponding with described fixing bar 111 position in described precast concrete beam 12
Hole 122.Such as, fixing bar 111 is bolt or screw rod, can reserve and mate with fixing bar in precast beam
Bolt hole.
In a kind of possible implementation, as shown in Figure 1 and Figure 5, described fixing bar 111 is through correspondence
Through hole 122 described precast concrete beam 12 is fixed on described ledge structure 110.
In a kind of possible implementation, as it is shown in fig. 7, be positioned in described precast concrete beam 12
The top of described through hole 122 has fixing groove 123, is provided with pad 124 in described fixing groove 123, and
By nut 31 and described pad 124, described precast concrete beam 12 is fixed on described ledge structure 110
On.The situation that the advantage of this fixed form is the plate of avoiding prefabricated deviation to cause cannot install with beam with
And the discrepancy in elevation being conveniently adjusted between contiguous prefabricated plate is to ensure the flatness of structure sheaf.
Additionally, as it is shown in figure 5, precast beam can also be reserved grout hole 127 and suspension centre 128.Wherein,
During assembling, precast beam can be sling by lifting appliance in suspension centre 128 position at precast beam two ends.
And, after precast beam assembles leveling with precoated plate, grouting material can be poured into prefabricated from grout hole 127
Between beam and precoated plate, and the space between prefabrication and assembly construction concrete and basic unit.
Embodiment three
Fig. 8 is the flow process of the assembly method of the prefabrication and assembly construction concrete of this utility model embodiment three
Figure.As shown in Figure 8, for the prefabrication and assembly construction xoncrete structure of any one structure in above-described embodiment
Layer, its assembly method may include that
Step 801, the appointment position that polylith precast slab is lifted in construction area；
Step 802, by a plurality of precast concrete beam lift by crane described polylith precast slab top, will
Described a plurality of precast concrete beam is placed into the both sides of described polylith precast slab；
Step 803, described precast slab and described precast concrete beam leveling will fix after, tear open
Unload on the ledge structure of suspender in described precast slab and described precast concrete beam；
Step 804, by suspender install duct be in the milk.
Specifically, first at the outer concentration pre-casting concrete slab of construction area and beams of concrete.Reach through health preserving
After design strength, by precoated plate and transporting precast beams to job site, see Fig. 6, by accordingly
Precoated plate is lain against in the basic unit of leveling by lifting appliance, adjusts precoated plate position to adjacent two pieces of precoated plates
Carrying out the most flat, then contiguous prefabricated plate seam crossing carries out essence flat, precast beam is put after completing by smart flat work
On ledge structure, and make the screw rod on precoated plate and the screw one_to_one corresponding on precast beam, then pass through
Nut and the connection of screw rod, be fixed together the contiguous prefabricated plate after leveling.Finally by reserved filling
Grouting material is poured into the space between prefabrication and assembly construction concrete and basic unit by slurry hole.Can be according to grouting
The requirement of strength of material determines the time of open to traffic.
This utility model has the advantage that with the contrast on common prefabrication and assembly construction road surface
The linking of common prefabricated assembly structural layer is the dowel steel by seam crossing or ribbet is attached,
The difficulty of construction of its structure sheaf is big, globality is poor, it is impossible to well solve surface evenness problem.Adopt
The prefabricated construction layer laid with this utility model is for this of common prefabricated construction layer
Defect, relies on precast beam to fix the precoated plate after leveling, makes the structure sheaf after assembling have higher smooth
Degree；And fill the space between prefabrication and assembly construction concrete and basic unit by pouring into grouting material, it is ensured that
The globality of structure and bearing capacity.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model
It is not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Cause
This, protection domain of the present utility model should described be as the criterion with scope of the claims.
