(2) binding and fastening a hoisting steel wire rope at the hoisting end (namely the end of the supporting frame for installing the limiting part) of the supporting frame 1;

(3) checking whether the connection of each component is qualified or not, and correcting in time if the connection of each component is unqualified;

(4) after the tower crane is qualified, the interphone contacts a tower crane driver (a professional company, the same below), the tower crane driver starts the tower crane, and a lifting hook on the tower crane is moved to a lifting position; hanging the hoisting steel wire rope to a lifting hook;

(5) slowly hoisting, wherein constructors keep smooth contact with a tower crane driver by using the interphone, and command the tower crane driver to slowly hoist; and ensuring that no person walks under the route hoisted to the construction site;

(6) when the crane moves to a construction point, a constructor instructs a tower crane driver to slowly lower the lifting hook to a reasonable construction position, and instructs the tower crane driver to stop the lifting hook from descending;

(7) a constructor removes the anti-falling part 2 at the lowest end from the supporting frame 1, and places the anti-falling part 2 at a safe position to avoid falling and hurting people; the lowest end anti-drop piece 2 is detached, so that a constructor can take the reinforcing steel bar 5 out of the support frame 1 for the construction of the concrete column inserted bar; after the reinforcing steel bars 5 are taken out, the reinforcing steel bars 5 are lifted up slightly and cross over the bottom anti-falling piece 7, so that the reinforcing steel bars 5 slowly slide to the bar inserting part; after the concrete column dowel bar construction is finished, transferring to the next concrete column, and when the reinforcing steel bar 5 on the device is used up; then the device is rotated to a steel bar storage point, and the steel bar 5 is installed on the device;

(3) The hoisting process must be kept balanced, and the phenomenon of uneven stress cannot occur.

(4) A professional staygorship must be equipped in the hoisting process.

(5) The stirrup at the joint bar construction part must be bound to a height of more than 2m, so that the reinforcing steel bar is prevented from falling off and hurting people.

(6) The reinforcing steel bars can be unloaded only by one at each time, so that falling and hurting of people are avoided.

(7) The constructors should wear the labor protection supplies according to the standard.

(8) The auxiliary device is suitable for steel bars which are heavy in weight and difficult to carry or steel bars which are long in length to be used in bar inserting operation (generally, the steel bars are of the weight or the length which can be carried by four adults).

As shown in fig. 1 to 3, for facilitating the lifting, a lifting ring 4 is provided on the supporting frame 1, and the lifting ring 4 and the limiting member 6 are located on the same side of the supporting frame 1. The hoisting ring 4 can conveniently hoist the whole device and can easily control the whole balance after hoisting.

As shown in fig. 1 to 4, the position-limiting members 6 are transversely provided with position-limiting grooves 8 at equal intervals side by side, and the number of the position-limiting grooves 8 can be 4, 6, 8 or 10. The limiting groove 8 can facilitate the insertion of the steel bar 5 used by the dowel into the limiting part 6. The spacing groove 8 is used for isolating the plurality of steel bars 5 inserted into the limiting part 6, so that the steel bars 5 on the limiting part 6 are orderly and orderly, and the steel bars 5 are taken out when subsequent steel bars are inserted conveniently.

The steel bar diameter that spacing groove 8 is applicable is phi 20 ~ 48mm to can satisfy the required reinforcing bar specification of different dowel bars. The number of the limiting grooves 8 can correspond to the number of the reinforcing steel bars 5 which can be arranged on the supporting frame 1. Generally, the length of the steel bar 5 arranged on the support frame 1 through the limiting groove 8 is 6 meters, the weight of the arranged steel bar is estimated according to the specification of the steel bar 5 arranged on the support frame 1, and then a proper tower crane, crawler crane or truck crane is selected for hoisting correspondingly.

The anti-falling part 2 is provided with a pin 203 which is matched and connected with the pin hole 204, and the pin 203 can be conveniently taken out of or inserted into the pin hole 204. When the anti-slip part 2 needs to be removed from the hoop part 3, the anti-slip part 2 can be pulled out from the hoop part 3 only by pulling the pin 203 out of the pin hole 204.

As shown in fig. 1 to 3, the hoop member 3 is formed by bending a steel bar. Aligned two by two with the longitudinal center line of the support frame 1 in the transverse direction of the support frame 1, and arranged at equal intervals in the longitudinal direction at the side edges of the support frame 1.

As shown in fig. 8 and 9, the construction of the bar inserting work is performed at the construction site of the apparatus of the present invention. As shown in fig. 10, the construction condition of the conventional artificial dowel is shown. By comparison, the investment of constructors is obviously less than that of the constructors in conventional construction. In the conventional construction, a plurality of (at least 5) constructors can only difficultly erect one steel bar each time, however, compared with the device, as can be seen from fig. 8 and 9, a plurality of steel bars in a vertical state exist, and the steel bars can be inserted for construction only by taking out the steel bars from the device, so that the device is convenient and quick; and constructors can simultaneously construct from two sides of the invention. The constructors to be invested are 3 persons at most. Therefore, the method is time-saving and labor-saving, has a high construction effect, can improve the overall construction progress, reduces the construction cost, and fully utilizes the tower crane resources on the construction site.

Application examples

A construction group A adopts the method to carry out dowel construction; and the B construction group adopts conventional joint bar construction (artificial vertical joint bar). Each group is assigned with the joint bar construction tasks of 8 concrete columns.

Personnel assignment: the A construction group comprises 3 persons, wherein 2 persons are constructors, and 1 person is a tower crane driver.

And B, 5 workers in the construction group.

All the steel bars used by the steel bars are transported to the steel bar inserting construction point.

At 8 am, two groups enter the construction state at the same time. And respectively carrying out the dowel construction on the tasks respectively connected.

By 50 minutes at noon, the a crew has completed the assigned tendon insertion task. And the construction group B just barely completes the joint bar task of 2 semi-concrete columns. The B construction group takes 8 hours and 40 minutes to complete all the bar inserting tasks. However, the time taken for the a construction group to complete the tendon insertion task was 2 hours and 50 minutes.

Therefore, the construction efficiency of the construction group A adopting the method for inserting the steel bars is obviously improved by more than three times compared with the construction of the conventional steel bars, and the construction workload of one day is more than three times compared with the construction of the conventional steel bars by adopting the method for constructing the steel bars. Moreover, the personnel distribution is less than that of the personnel required by the conventional dowel construction; the labor cost of the A construction group is 1200 yuan/day and the labor cost of the B construction group is 2000 yuan/day according to the labor price of 400 yuan/day, and the labor cost is saved by 800 yuan per day. Therefore, the construction efficiency can be obviously improved, the engineering construction progress is improved, the engineering construction period is shortened, the labor expenditure is reduced, the engineering construction cost is reduced, and the economic benefit of the engineering construction is improved.
