Embodiment four
Fig. 9 is the assembly method of the sleeper beam formula prefabrication and assembly construction concrete of this utility model embodiment four
Flow chart.As it is shown in figure 9, for the prefabricated dress of sleeper beam formula of any one structure in above-described embodiment
Joining concrete, its assembly method may include that
Step 901, the appointment position that a plurality of precast concrete beam is lifted in construction area；
Step 902, for each piece of described precast slab, described precast slab is lifted to
The top of the described a plurality of precast concrete beam in construction area, bottom by described precast slab
Under the state of the position that mounting groove is directed at each described a plurality of precast concrete beam, by described precast slab
It is placed in described construction area；
Step 903, described precast slab and described precast concrete beam leveling will fix after, tear open
Unload the suspender in the built-in fitting of described precast slab；
Step 904, 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 a and Fig. 6 b, pass through
Precast beam is lain against in the basic unit of leveling by corresponding lifting appliance, is placed on precast beam by precoated plate, in advance
Screw in making sheet will be corresponding to the screw rod on pre-Ying Liang, the screw rod being then passed through on precast beam and the spiral shell on plate
The installation accuracy of hole fine setting precoated plate, with the flatness of structure sheaf after guarantee assembling.Finally by reserved
Grouting material is poured into the space between sleeper beam formula prefabrication and assembly construction concrete and basic unit by grout hole.Permissible
Requirement of strength according to grouting 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
With the sleeper beam formula prefabricated construction layer of this utility model laying for common prefabricated construction layer
This defect, rely on the regulation of precast beam and basic unit, the most again by the bolt on precast beam with prefabricated
