It is dynamic.
The structure of the rolling cage is as shown in Figure 5, Figure 6, including work can be used in two horizontally disposed stringers 3, two stringers
Word steel, the spacing of two stringers are less than the diameter of steel reinforcement cage, to enable steel reinforcement cage to be supported on rolling cage；Pass through company between two stringers
Extension bar 4 connects, and steel pipe can be used in connecting rod and I-steel welds.At least two idler wheels 2 are respectively arranged at the top of every stringer,
Cylinder wheel can be used in the idler wheel 2.
(2) as shown in Figure 1 and Figure 2, one locating rack is set in rolling cage side, the locating rack includes a pedestal 5, pedestal
One vertical Telescopic supporting rod 6 of upper fixed setting is welded with horizontally disposed upper clamp plate 7 and lower clamp plate 8, upper folder on support rod
The spacing of plate and lower clamp plate is equal or slightly larger than the diameter of steel reinforcement cage main reinforcement 9, enable to be placed in steel reinforcement cage main reinforcement upper lower clamp plate it
Between.The support rod height for adjusting locating rack, the top surface and steel reinforcement cage axle center for making lower clamp plate are the same as high.
The structure of the locating rack as shown in fig. 7, comprises a pedestal 5, support rod 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 solid
Determine in pipe, the upper clamp plate 7 and lower clamp plate 8 are welded in adjustable pipe；Opposite spiral shell there are two being set on the tube wall of the fixing pipe
Hole, be spirally connected in each screw hole 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 rod height, location nut is first unclamped, the length in adjustment adjustable pipe insertion fixing pipe makes the top of lower clamp 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, flushes a main reinforcement 9 to be curved of steel reinforcement cage 1 with the axle center of steel reinforcement cage 1；Running fix
Main reinforcement to be curved is placed between locating rack upper clamp plate 7 and lower clamp plate 8 by frame, so that main reinforcement to be curved is close to lower clamp plate top surface, and make to be curved
9 end of main reinforcement is exposed except upper lower clamp plate, and the length of end exposed portion is the scheduled bending length of main reinforcement to be curved.Such as Fig. 1, figure
State shown in 2.
(4) as shown in Figure 3, Figure 4, curved muscle tool is inserted into the end of main reinforcement 9 to be curved, and with curved muscle tool by main reinforcement to be curved
End is bent downwardly scheduled angle.
Spanner or other the curved muscle tool of machinery can be used in curved muscle tool.But common curved muscle tool is difficult to control curved
Qu Jingdu.The present invention devises a kind of Special bending muscle tool thus, is a kind of curved muscle bar, 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；10 front end of handle is axially arranged with multipair spring steel ball 12 along handle, axially sets on the rear end tube wall of casing 11 along casing
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 of spring steel ball 12 is stuck in a pair of of handle dowel hole 13；Close to casing front end on the tube wall of described sleeve pipe 11
Multipair reinforcing bar dowel hole 14 is axially arranged with along casing, and 15 activity of a bolt is interspersed in one pair of them reinforcing bar dowel hole 14.
After the completion of (5) main reinforcement bendings, curved muscle tool is removed, locating rack is temporarily removed, steel reinforcement cage is rotated, makes steel reinforcement cage
Next main reinforcement 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 connector
Muscle bending is completed.
For convenience of construction, and speed of application is improved, the present invention can make the casing 11 of curved muscle bar when designing curved muscle bar in advance
The predefined curved length of the main reinforcement of upper every a pair of of reinforcing bar dowel hole 14 to a kind of corresponding diameter in the distance between casing front end, and
Its corresponding main reinforcement diameter is marked by each pair of reinforcing bar dowel hole；Make each pair of handle positioning on the casing 11 of curved muscle bar in advance
A kind of predefined curved length of the main reinforcement of the corresponding diameter of pin hole 13, and its corresponding main reinforcement is marked by each pair of handle dowel hole
Diameter.Because the diameter of steel reinforcement cage main reinforcement is commonly known, in this way in curved muscle bar in use, according to the curved steel reinforcement cage master of institute
Muscle diameter directly just can determine the length of curved muscle bar and the length of main reinforcement insertion casing.
When curved muscle bar makes, the mode of the position of a pair of of reinforcing bar dowel hole 14 on the casing of curved muscle bar is preset such as
Under:
According to construction experience, the length of the predefined curved part of the main reinforcement of every kind of diameter is generally 5 times of the main reinforcement diameter, according to
This can determine on curved muscle rod bush each pair of reinforcing bar dowel hole the distance between to casing front end.
The mode for presetting the position of a pair of of handle dowel hole 13 on the casing of curved muscle bar is as follows:
Firstly, determining the predefined curved angle of main reinforcement by following formula:
Wherein d is the diameter of main reinforcement, and α is the scheduled bending angle of main reinforcement.
Then in the state that main reinforcement to be curved is in above-mentioned steps (3), i.e., main reinforcement 9 to be curved flushes, simultaneously with 1 axle center of steel reinforcement cage
It is placed between locating rack upper clamp plate 7 and lower clamp plate 8, the length of the upper lower clamp plate 5d of end exposing, adjusts curved muscle pole length, make curved muscle
When bar front end and main reinforcement to be curved form α angle, curved muscle rod rear end just contacts to earth, the curved muscle pole length being subject at this time, in curved muscle
A pair of of handle dowel hole 13 is set on rod bush 11, and it is fixed to handle so that a pair of of spring steel ball 12 is stuck in this
It can just make the length of curved muscle bar holding at this time when the pin hole 13 of position, it is straight to its corresponding main reinforcement is marked by handle dowel hole at this
Diameter；The multipair handle dowel hole of corresponding multiple diameter main reinforcement is predefined by the above method.
As shown in figure 3, when using curved muscle bar Specific construction, it is straight at this according to the diameter of known steel reinforcement cage main reinforcement 9 to be curved
It is inserted into bolt 15 in a pair of of reinforcing bar dowel hole 14 on curved muscle bar corresponding to diameter main reinforcement, main reinforcement 9 to be curved is inserted into curved muscle bar
In casing 11 until touching bolt 15, it is scheduled bending length that main reinforcement, which is inserted into sleeve portion,；Slide curved muscle bar handle
10, it is caught in a pair of of spring steel ball 12 of its front end on casing in a pair of of handle dowel hole 13 corresponding with the diameter main reinforcement；
Then pressing down on handle 10 can be by the main reinforcement connector to be curved of predetermined length until so that 10 rear end handle of handle is just contacted to earth
Bend to predetermined angular.
Convenient to plug convenient for bolt 15, steel ball pin can be used in the bolt 15 being interspersed in reinforcing bar dowel hole 14.
