Embodiment
Below in conjunction with accompanying drawing, by an embodiment, the method for the present invention is illustrated.The specific reality of the present invention
Existing step is as follows：
(1) as shown in Figure 1 and Figure 2, steel reinforcement cage 1 is lain in a horizontal plane on a rolling cage, the rolling cage both sides are set respectively
There are at least two rollers 2, steel reinforcement cage is supported on the roller 2 of rolling cage 1, manual rotation's steel reinforcement cage, can make steel reinforcement cage 1 freely
Rotate.
As shown in Figure 5, Figure 6, including two horizontally disposed longerons 3, two longerons can use work to the structure of the rolling cage
Word steel, the diameter for being smaller than steel reinforcement cage of two longerons, to enable steel reinforcement cage to be supported on rolling cage；Pass through company between two longerons
Extension bar connection 4, connecting rod can use steel pipe to be welded with I-steel.At least two rollers 2 are respectively arranged with the top of every longeron,
The roller 2 can use cylinder wheel.
(2) as shown in Figure 1 and Figure 2, one locating rack is set in rolling cage side, the locating rack includes a base 5, base
It is upper that a vertical Telescopic supporting rod 6 is fixedly installed, it is welded with horizontally disposed train wheel bridge 7 and lower plate 8, upper folder on support bar
The spacing of plate and lower plate is equal or slightly larger than the diameter of steel reinforcement cage cage bar 9, enable to treat steel reinforcement cage cage bar be placed in lower plate it
Between.The support bar height of locating rack is adjusted, makes the top surface of lower plate same high with steel reinforcement cage axle center.
The structure of the locating rack as shown in fig. 7, comprises a base 5, its support bar 6 are bushing type stretching structure, including
One fixing pipe 61 and an adjustable pipe 62, the lower end of the fixing pipe 61 and tube chamber welds with base, the activity, 62 lower end are interspersed in admittedly
In fixed tube, the train wheel bridge 7 and lower plate 8 are welded in adjustable pipe；The tube wall of the fixing pipe is provided with two relative spiral shells
Hole, be spirally connected in each screw a location nut 63, and the front end of the location nut 63 holds out against the adjustable pipe in fixing pipe 61
62；When adjusting support bar height, location nut is first unclamped, adjusts the length in adjustable pipe insertion fixing pipe, makes the top of lower plate
Face and steel reinforcement cage axle center with it is high when, then screwed in place nut fixes adjustable pipe.
(3) steel reinforcement cage 1 is rotated, a cage bar 9 to be curved of steel reinforcement cage 1 is flushed with the axle center of steel reinforcement cage 1；Running fix
Frame, cage bar to be curved is placed between locating rack train wheel bridge 7 and lower plate 8, cage bar to be curved is close to lower plate top surface, and made to be curved
The termination of cage bar 9 is exposed outside lower plate, and the length of termination exposed portion is the predetermined bending length of cage bar to be curved.Such as Fig. 1, figure
State shown in 2.
(4) as shown in Figure 3, Figure 4, curved muscle instrument is inserted into the termination of cage bar 9 to be curved, and with curved muscle instrument by cage bar to be curved
Termination is bent downwardly predetermined angle.
Curved muscle instrument can use spanner, or other mechanical curved muscle instrument.But common curved muscle instrument is difficult to control curved
Qu Jingdu.For this, the present invention devises a kind of Special bending muscle instrument, is a kind of curved muscle bar, and its structure is as shown in Figure 8, Figure 9, described
Curved muscle bar includes one handle 10 and sleeve 11, and the rear end of the handle 10 is handle, and front end activity is interspersed in described sleeve pipe 11
Rear end；The front end of handle 10 is axially arranged with multipair spring steel ball 12 along handle, is axially set along sleeve pipe on the rear end tube wall of sleeve pipe 11
There is multipair handle dowel hole 13, the spacing of multipair spring steel ball 12 is corresponding with the spacing of multipair handle dowel hole 13, and
And at least a pair of spring steel balls 12 are stuck in a pair of handle dowel holes 13；Close to sleeve pipe front end on the tube wall of described sleeve pipe 11
It is axially arranged with multipair reinforcing bar dowel hole 14 along sleeve pipe, the activity of a latch 15 is interspersed in one pair of which reinforcing bar dowel hole 14.
After the completion of (5) cage bar bendings, curved muscle instrument is removed, temporarily removes locating rack, steel reinforcement cage is rotated, makes steel reinforcement cage
Next cage bar to be curved flushed with steel reinforcement cage axle center；Repeat the above steps (3) and (4), until by all masters of steel reinforcement cage joint
Muscle bending is completed.
For convenience of construction, and speed of application is improved, the present invention can make the sleeve pipe 11 of curved muscle bar in advance when designing curved muscle bar
Upper every a pair of reinforcing bars dowel hole 14 arrives a kind of predefined curved length of the corresponding cage bar of diameter in the distance between sleeve pipe front end, and
Its corresponding cage bar diameter is marked by each pair reinforcing bar dowel hole；Make in advance each to handle positioning on the sleeve pipe 11 of curved muscle bar
A kind of predefined curved angle of the corresponding cage bar of diameter of pin-and-hole 13, and its corresponding cage bar is marked by each pair handle dowel hole
Diameter.Because the diameter of steel reinforcement cage cage bar is commonly known, so in curved muscle bar in use, according to the steel reinforcement cage master bent
Muscle diameter, it directly just can determine that the length of curved muscle bar and the length of cage bar plug-in-sleeve.
When curved muscle bar makes, the mode of the position of a pair of reinforcing bar dowel holes 14 on the sleeve pipe of curved muscle bar is preset such as
Under：
According to construction experience, the length of the predefined curved part of cage bar of every kind of diameter is generally 5 times of the cage bar diameter, according to
This can determine that on curved muscle rod bush each pair reinforcing bar dowel hole the distance between to sleeve pipe front end.
The mode for presetting the position of a pair of handle dowel holes 13 on the sleeve pipe of curved muscle bar is as follows：
First, a kind of predefined curved angle of cage bar of diameter is determined by empirical equation：
Wherein d is the diameter of this kind of model cage bar, and α is the predetermined angle of bend of the cage bar of this kind of diameter.
Then in the state of cage bar to be curved is in above-mentioned steps (3), i.e., cage bar 9 to be curved flushes, simultaneously with the axle center of steel reinforcement cage 1
Be placed between locating rack train wheel bridge 7 and lower plate 8, lower plate 5d length is exposed in termination, adjust curved muscle pole length, make curved muscle
When bar front end forms α angles with cage bar to be curved, curved muscle rod rear end just contacts to earth, and is defined by curved muscle pole length now, in curved muscle
A pair of handle dowel holes 13 are set on rod bush 11, and a pair of spring steel balls 12 is stuck in this and handle is determined
The length of curved muscle bar holding now can just be made during the pin-and-hole 13 of position, it is straight to marking its corresponding cage bar by handle dowel hole at this
Footpath；The multipair handle dowel hole of corresponding multiple diameter cage bar is predefined by the above method.
As shown in figure 3, during using curved muscle bar Specific construction, it is straight at this according to the diameter of known steel reinforcement cage cage bar 9 to be curved
Latch 15 is inserted in a pair of reinforcing bar dowel holes 14 on curved muscle bar corresponding to the cage bar of footpath, cage bar 9 to be curved is inserted into curved muscle bar
In sleeve pipe 11 untill latch 15 is touched, cage bar plug-in-sleeve part is predetermined bending length；Slide curved muscle bar handle
10, a pair of spring steel balls 12 of its front end is caught on sleeve pipe in a pair of handles dowel hole 13 corresponding with the diameter cage bar；
Then handle 10 is pressed down on, is made untill the rear end handle of handle 10 just contacts to earth, you can by the cage bar joint to be curved of predetermined length
Bend to predetermined angular.
It is convenient to be plugged for ease of latch 15, and the latch 15 being interspersed in reinforcing bar dowel hole 14 can use steel ball pin.
