In formula steel bar connecting structure, the length in reserve of described reserved steel bar 2 is 500mm-1000mm.When two is right
When need not arrange horizontal structure 5 between the prefabricated wall column 1 connect, the length in reserve of usual reserved steel bar 2 is
During about 500mm, the working place needed for workmen can be met；Prefabricated wall column 1 when two docking
Between when needing to arrange horizontal structure 5, reserved length needs to increase the thickness of this horizontal structure 5, this
Time, general reserved length is between 800mm-1000mm.
Please continue to refer to Fig. 1, the present embodiment also discloses a kind of prefabricated wall column 1 one-part form connecting method for reinforcing bars,
The i.e. construction method of prefabricated construction, uses the prefabricated wall column 1 one-part form steel as described in embodiment one
Muscle attachment structure, comprises the steps:
The first step, the prefabricated wall column of ground floor 1 of constructing on the basis of wall column；
Second step, lifts the prefabricated wall column of the second layer 1, using the second layer dry wall of wall column 1 prefabricated as top
It is upper that the lower end reserved steel bar 2 of post 1 inserts as the prefabricated wall column of ground floor 1 when front lower place dry wall post 1
In the sleeve 3 of the reserved steel bar 2 of end, and grouting material is used to be executed toward grouting in sleeve 3 by reserved grout hole
Work；
3rd step, using horizontal structure reinforcing bar 4 through as when the ground floor dry wall of front lower place dry wall post 1
The reserved steel bar 2 of the upper end of post 1, and carry out bar connecting；
4th step, Feng Mohou, to horizontal structure 5 and the butted part of the most upper and lower two prefabricated wall columns 1
Carry out formed by integrally casting.
5th step, repetition second step, to the 4th step, is the most upwards constructed, until completing the prefabricated wall column of all layers
The construction of 1.
On the one hand, between prefabricated wall column 1 of the present utility model, reinforcing bar uses sleeve 3 to connect, the one of sleeve 3
End is connected with reserved steel bar 2 bolt of a prefabricated wall column 1, and the other end of sleeve 3 is for another prefabricated wall column 1
Reserved steel bar 2 insert and connected by grouting, improve between reinforcing bar connect strength and stiffness, it is ensured that
The safety of structure, and avoid using electric welding to connect the toxic and harmful produced, ensure workmen's
Working security, beneficially environmental conservation.
On the other hand, this utility model, when the most adjacent two prefabricated wall columns 1 connect, carries out level simultaneously
The construction of structure 5, therefore, has only to the most prefabricated wall column 1 between each layer i.e. adjacent level structure 5
Between connection (i.e. reinforcing bar one-part form connect), connect two in comparing each layer of Normal practice between prefabricated wall column 1
Secondary way, effectively reduces sleeve 3 consumption, reduces construction cost.Additionally, it is pre-in this utility model
Wall column 1 processed can be the most prefabricated, does not accounts for the duration, and working (machining) efficiency is high, it is possible to effectively accelerating construction progress.
Preferably, in the described first step, stagger on the basis of described wall column reserved reinforcement foundation, reinforcement foundation
Screw top connect a sleeve 3 as above, the reserved steel bar 2 of the lower end of the prefabricated wall column of ground floor 1
Insert in the sleeve 3 of described reinforcement foundation, grouting construction in the sleeve 3 of described reinforcement foundation, after grouting,
Wall column 1 prefabricated to ground floor pours after the docking section enfeoffment mould on wall column basis.Due to base plate in advance with
Wall column basis is constructed complete together, therefore, is attached between the prefabricated wall column of ground floor 1 and wall column basis
Time, it is not necessary to carry out the construction of horizontal structure 5.
Preferably, after the 5th step, by roof steel bar through the prefabricated wall column 1 being currently located at the top
The reserved steel bar 2 of upper end, carry out bar connecting, Feng Mohou, top board poured.So, permissible
Complete the construction of the top board i.e. horizontal structure of the superiors so that shape between top board and the prefabricated wall column 1 of the top
One-tenth is reliably connected.
In the present embodiment, described prefabricated wall column 1 is prefabricated post.Certainly, described prefabricated wall column 1 can also be
Dry wall, as shown in Figure 2.The precast wall body method of attachment comparing existing routine is at floor, prefabricated panel
Between reserved steel plate, then use bolt to carry out being mechanically connected or use electric welding to connect, adjacent level structure
Between precast wall body at least need twice connection construction, not only waste time and energy, the usage amount of corresponding steel plate
Relatively big, the problem causing high cost, between prefabricated wall column of the present utility model, reinforcing bar uses sleeve connection,
One end of sleeve i.e. lower end is connected with a prefabricated wall column i.e. reserved steel bar bolt of the prefabricated wall column in lower section, sleeve
The i.e. upper end of the other end is inserted for another the prefabricated wall column i.e. reserved steel bar of the prefabricated wall column in top and passes through grouting even
Connect, improve the strength and stiffness connected between reinforcing bar, it is ensured that the safety of structure, and avoid using electricity
Weldering connects the toxic and harmful produced, and ensures the working security of workmen, beneficially environmental conservation.
Additionally, horizontal structure reinforcing bar of the present utility model is before the butted part of the prefabricated wall column of upper and lower pours,
The reserved steel bar of the upper end of prefabricated wall column through lower section, and carry out bar connecting, horizontal structure is pre-with upper and lower
The butted part formed by integrally casting of wall column processed forms, and the top of concrete of the prefabricated wall column in described lower section is close to described water
The lower surface of flat structure.Owing to when the prefabricated wall column of each upper and lower is attached, constructing one layer the most simultaneously
Horizontal structure, therefore, has only to the connection of a dry wall intercolumniation between each layer i.e. adjacent level structure,
Compare dry wall intercolumniation in the most each layer of Normal practice and connect the way of twice, effectively reduce the steel such as sleeve
Use consumption, reduce construction cost.
Foregoing description is only the description to this utility model preferred embodiment, not to this utility model scope
Any restriction, any change that the those of ordinary skill in this utility model field does according to the disclosure above content,
Modify, belong to the protection domain of claims.
