Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in fig. 1~fig. 5, present embodiment discloses a kind of outer precast constructions for pier column and its outer prefabricated interior existing
Pour pier column, including cushion cap 1, outer precast construction 2, circular pedestal 3, embedded bar 4.
Implementing procedure:
Step 1: outer precast construction (meet after strength grade transporting and hoisting to scene).
Outer precast construction 2 includes prefabricated components 21, vertical reinforcement 22, stirrup 23, grout sleeve 24 and Grouting Pipe 25, outer pre-
Component 21 processed is closed hollow frame body, and vertical reinforcement 22, stirrup 23, grouting cylinder 24 and Grouting Pipe 25 are arranged the two of outer prefabricated components
Between layer hollow frame body, vertical reinforcement 22 is vertically laid from the top of prefabricated components 21 to bottom end, and 23 lateral circular of stirrup is perpendicular
To on reinforcing bar 22, the bottom end of prefabricated components 22 is arranged in grout sleeve 24, and vertical reinforcement 22 is arranged in grout sleeve 24, grouting
24 bottom end of sleeve is equipped with a connecting hole, and Grouting Pipe 25 is arranged in the two sides of grout sleeve 24 and connect with grout sleeve 24.It is outer pre-
Structure 2 processed is transported after directly being made from factory toward construction site, and outer 2 structure of precast construction is simple, and lighter in weight is readily transported.
Step 2: cast-in-place cushion cap embedded bar:
Live cushion cap 1 uses cast-in-place form, and cushion cap 1 is equipped with the good connecting hole phase with 24 bottom end of grout sleeve pre-buried in advance
Corresponding embedded bar 4 and it is attached around pedestal 3 with precast construction 2, ring wall reinforcing bar 31 is equipped in pedestal 3, to outer prefabricated
When structure 2 is transported to construction site, the standing of outer precast construction 2 is placed into pedestal 3, embedded bar 4 is inserted into grouting
In the connecting hole of 24 bottom end of sleeve.Embedded bar 31 is Ribbed Bar.
Step 3: outer precast construction is connect with cushion cap:
The outer precast construction 2 in scene is connect using 24 type of attachment of grout sleeve with cushion cap 1, i.e., is inserted into pre-buried Ribbed Bar
Then the grout sleeve 24 in inner cavity band connection hole pours into dedicated high-strength, contraction-free grouting concrete, reach and connect higher than parent material of reinforcement rebar intensity
Effect is connect, then formwork erection cast-in-situ base at outside ring wall reinforcing bar 31, guarantees effective connection of outer precast construction 2 and cushion cap 1, finally
The empty intra-bladder instillation of outer precast construction 2 forms pier column after waiting by force, makes outer precast construction with the slightly expanded concrete of intensity again
2 are more bonded with cushion cap and around pedestal 3, and stability is higher.
In conclusion the utility model can effectively solve the problem that technical problem, social concern in construction, it is hidden to prevent safety
Suffer from, improves productivity effect.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
