Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is a PC girder intercepting device that manufactures girders used at a construction site and moves them laterally to a temporary rocky shore during bridge construction work. It is related to.

(Conventional technology) Currently, in the construction work using PC girders, the PC girder is manufactured at the construction site, and the completed PC girder is moved laterally from the manufacturing site to the Machisomata base (the horizontal movement of 20 PCs is carried out by intercepting work). ) and then a new PC girder is made again at the manufacturing site.

In this way, the necessary number of PC girders are manufactured and kept on standby for a long time, and are sequentially moved vertically toward construction work to construct the bridge. , 2, the PC girder is moved, and the work to intercept the movement can be roughly divided into the following two types.

■ A running rail is installed on the sleeper using a hydraulic jack and a roller, and a rocking horse or iron horse is installed on the -L of the sleeper via the rollers, and the hydraulic jack is used to move the rail forward, backward, left, and right using the adjusting material. Hold the PC digits in several places.

■ Method using a bridge crane A bridge crane is installed at the construction site, and the crane is used to carry out the work.
Fish the spars.

(Problem to be solved by the invention) As described above, there are currently two types of usurpation methods. Since a hydraulic jack is used, it has to be raised at the same time, and since the hydraulic jack 1/lower is small, it has to be replaced many times and many adjustment phases have to be prepared, and there is always a vertical load on the hydraulic jack during work. You have to make it hang.

In addition, a large number of PC girder O rotation prevention OI components are required (3 people on one side and 6 people on both sides for Azusa-dori), and attention must be paid to the reaction force of the F section, so skilled workers are required to carry out the interfering work. It takes about half a day for each one.

In the latter case, although it is safe and can be carried out by a small number of people at the construction site, the rock equipment and equipment can become a fire hazard, and it is expensive.

In this way, I felt that there were a lot of inconveniences when it came to stealing work.

(Means for resolving the problem) The present invention solves these inconveniences: '+! f l, Safe and easy stealing 1} work is completed at the construction site 2.8

(for production) Next, the operation of the present invention will be explained.

Before moving the PC girder product (73), attach the handle (
(omitted in the figure), rotate the support shaft (Ma) on the ball (3), move the horizontal rail frame (1) up and down using the fixing material (6), and set it horizontally (1) and the horizontal rail (9). Place it on it and keep it horizontal.

After assembling everything except for the bridge (IOC, L girder and nose (55)), place it on the traversing rail (9), and at the same time, install the transverse girder drive device (16)
Move the chain (19) to turn the wheel (13) via the pongee (14), the chain south car (18), and move the traversing rail (
9) Move the pedestal (10) to the appropriate position above.

In the meantime, insert the long grooves (66) of the bracket (65) into the tightening bolts (74) provided on both ends - 1 and both sides of the PC girder product (73), press with washers (71), and tighten the nuts. and fix the brackets (65) to both upper sides of both ends of the C girder product (73). After that, the reaction force receiver (64) is connected to the PC girder product (7).
As shown in Fig. 4, the abutment (53) is suspended by a 2.8t bridge crane (not shown in the figure) so that the abutment (53) is on the side of the movable frame (46) assembled on the frame (10). (53)
The long groove (54) is fitted into the fixed bottle (52) and placed.

After placing the girder tree nose (55) in this way, go up the fishing rod (7) between the reinforcing material (61) and (6P) of the girder support beam (60).
2) is inserted from above and protrudes from the backing plate (69) between the reinforcing plates (68) and (68') to remove the water in the girder support beam (60) which is swinging with the bottle (63). While checking f, tighten the nuts on both ends of the fishing rod (72) and fish the girder support beam (60) and bracket (65)! ] Connect and fix with the rod (72).

At this time, the girder suspension is no;
) with the fulcrum as the fulcrum, no < 1, reaction force receiver (64)
Securely support the PC girder product (73) using the bracket (65) and the girder suspension nose (55) to prevent it from swinging back and forth, left and right. When both ends of the PC girder product (73) are supported by the girder suspension north (55) in this way, the lift drive unit (20) is driven by the switch connected to the control panel (23) and the chain gear is moved. The rotation is transmitted from (21) to the intermediate shaft (48) via the chain (49) and chain gear (50) to turn the screw jack (47).

When the screw jack (47) rotates, the crossbeam (30) is pushed up by the screwed support (39), and the girder (55) is lifted by the fixed bin (52) through the long groove (54).
) is pushed down at the same time and the PC girder product (73) is lifted up with the fishing rod (72).

At this time, the transfer column (
35) is guided and the PC girder product (73) can be lifted without wobbling in order to prevent the girder lifting nose (55) from wobbling laterally.

Then, when it is lifted to a predetermined height, the lifting drive device (2
0) to stop the rotation of the screw jack (47), correct the lifting of the cross girder (30), stop the lifting of the PC girder product (73), and finish the lifting work of the PC girder product (73).

Then, the work of moving the PC girder product (73) laterally begins.

Move the traverse drive device (16) again, move the 17 wheels (13) together to any position on the traverse rail (9), stop the traverse drive device (16), and stop the PC girder product (73). let

When this state is reached, drive the lifting drive device (20) again in the opposite direction to the above, and the screw jack (47)
The crossbeam (30) is lowered and the girder suspension nose (55) is lowered together with the crossbeam (30) by its own weight and the weight of the PC girder product (73) to the appropriate position. After installing support rods on both sides of the PC girder product (73), the PC girder product (73) is completely lowered to the standby bench and the lifting drive device (20) is stopped.

Then, loosen both ends of the fishing rod (72) and pull out the fishing rod (72) from the girder support beam (60) and bracket (65) in the -1 direction.At the same time, loosen the tightening bolt (74) and also loosen the bracket ( 65) is also removed from the PC digit product (73) to complete the movement of the PC digit product (73).

In addition, all figures 1, 3, and b are PC girder products (73).
The lower end of the movable column (35) is shown in the white position (29).
The movable frame (46) is lowered to a position approaching the top surface, and at that time, the pongee part of the screw jack (47) is attached to the cover (38).
).
