Stretching force, also without using the circumferential prestressed technique of reply on arcual component, the reinforcing bar content in arched concrete component
Higher, concrete easily cracks without preload pressure, and durability is poor, and component is also easily damaged in use, and performance is low,
Service life is short.
Utility model content：
The utility model provides a kind of arcual component prestress application device, this is reasonable in design, novel, technique behaviour
Make step simply, conveniently, prestress application device is added in arcual component, prestress application device can effectively increase
To the restraining force of deformed bar, ensure that deformed bar suffers oppression domed shape, so as to be effectively ensured to arched concrete
Component smoothly applies circumferential prestressing force, and the intensity and performance of component has also been effectively ensured, and effectively increases component and uses structure
The service life of arched concrete made of part, the muscle set of wearing in component are penetrated into steel reinforcement cage body easy to deformed bar, and
And can realize during deformed bar tensioning wear muscle set inner wall in it is travelling freely, suitable for be widely popularized use, solve existing
Problem present in technology.
The utility model is that technical solution is used by solving above-mentioned technical problem：
A kind of arcual component prestress application device, includes the reinforcing bar cage body of an arch, along steel reinforcement cage in steel reinforcement cage body
Body circumferential array is welded with several reinforcing bars radially put and wears ledges, and the reinforcing bar wears the reinforced frame that ledges is a closing
Body, wears in reinforcing bar and transverse bar and vertical bars is welded with ledges, several are welded with transverse bar or vertical bars axially along reinforcing bar cage body
Circumferentially disposed wears muscle set.
The both ends for wearing muscle set are horn-like opening.
The lower end pad of the vertical bars is equipped with cover to reinforcement frame.
Using the above structure, this is reasonable in design, novel for the utility model, and technological operation step simply, conveniently, is being encircleed
Prestress application device is added in shape component, prestress application device can effectively increase the constraint to deformed bar
Power, ensures that deformed bar suffers oppression domed shape, smoothly applies circumferential direction to arched concrete component from so as to be effectively ensured
Prestressing force, has also been effectively ensured the intensity and performance of component, has effectively increased component and the arch coagulation made of component
The service life of soil, the muscle set of wearing in component is penetrated into steel reinforcement cage body easy to deformed bar, and can realize prestress steel
During muscle tensioning wear muscle set inner wall in it is travelling freely, suitable for be widely popularized use.
Brief description of the drawings：
Fig. 1 is the overlooking the structure diagram of the utility model.
Fig. 2 is the structure diagram that the utility model reinforcing bar wears ledges.
In figure, 1 reinforcing bar cage body, 2 reinforcing bars wear ledges, and 21 transverse bars, 22 vertical bars, 23 wear muscle set, 24 cover to reinforcement framves.
Embodiment：
In order to clarify the technical characteristics of the invention, below by embodiment, and its attached drawing is combined, to this reality
It is described in detail with new.
As shown in figs. 1-2, a kind of arcual component prestress application device, includes the reinforcing bar cage body 1 of an arch, in reinforcing bar
Several reinforcing bars radially put being welded with along 1 circumferential array of reinforcing bar cage body in cage body 1 and wearing ledges 2, the reinforcing bar wears muscle
Frame 2 is the reinforcing steel bar shelf of a closing, is worn in reinforcing bar and transverse bar 21 and vertical bars 22 are welded with ledges, on transverse bar 21 or vertical bars 22
It is welded with several and covers 23 axially along the circumferentially disposed muscle of wearing of reinforcing bar cage body 1.
The both ends for wearing muscle set 23 are horn-like opening.
The lower end pad of the vertical bars 22 is equipped with cover to reinforcement frame block 24.
A kind of method with the arcual component prestress application device concrete, includes the following steps：
S1 is modeled
The punching block of arch is produced with steel plate, releasing agent is brushed on the inner wall of punching block；
S2 makes the prestress application device of precast concrete arcual component
S3 places deformed bar:
Deformed bar is interspersed in reinforcing bar cage body 1 from one end of reinforcing bar cage body 1, deformed bar is in reinforcing bar cage body 1
Wearing in muscle set 23 in same circumferential direction is inside interspersed in successively；
S4 tensioning
Apply circumferential stretching force to deformed bar, and anchor pinning deformed bar；
S5 is poured into a mould
Concrete is poured into a mould to punching block inside, vibration compacting, produces arched concrete；
S6 is conserved
It is quiet stop 2 it is small when after, using steam curing or natural curing
S7 is demoulded
Slough punching block.
The step S2 comprises the following steps：
