in step S1, the anchor hanger 1 is assembled.
In the above steps, tools and corresponding parts are prepared according to the structure of the anchor hanger 1. In this embodiment, the load-bearing parallel 12 may be installed after the hanger frame 11 is built. After the hanger frame 11 is installed, the stopper 13 is further welded to facilitate the alignment. The distance between the limiting parts 13 can be determined by the diameter length of the anchor rod 2 to be clamped, and a certain allowance is reserved. The remaining margin allows for subsequent ease of installation of the anchor rod 2.
In step S2, the anchor rods 2 are sequentially hoisted on the anchor rod hanger 1.
In the above steps, the anchor rod 2 is transferred to the position of the limiting piece 13 corresponding to the anchor rod hanger 1 by using the lifting tool, and the positions of the limiting pieces 13 are different according to the different lengths. In order to protect the anchor rod 2 from being worn by the limiting piece 13, a protective sleeve or a rubber ring made of plastic can be sleeved at the limiting piece 13. The length of the limiting piece 13 is controlled to be 60-120% of the diameter length of the anchor rod 2 and is smaller than the distance between the two layers of bearing parallel units 12.
In step S3, the entire anchor hanger 1 after the anchor rod 2 is installed is lifted to a predetermined position.
In the above process, after the anchor rod 2 is installed on the whole anchor rod hanger 1 according to the preset position, the whole anchor rod hanger 1 is lifted to the specified position at one time. In addition, the anchor rod hanging frame 1 can be used as a tool for providing temporary placement besides one-time transportation, and the anchor rod 2 is installed to a designated position by using a lifting tool, so that the positioning prompt function is realized, and the condition that the anchor rod 2 which is not corresponding to the lifting tool or the installation position is deviated is avoided.
In this embodiment, the anchor rod 2 may be lifted at one time after the anchor rod hanger 1 is assembled, or the anchor rod 2 may be lifted alternately during the process of assembling the anchor rod hanger 1. Taking the process of assembling the anchor rod hanger 1 as an example, alternatively hoisting the anchor rods 2, please refer to fig. 11, the step S1 of assembling the anchor rod hanger 1 specifically includes the steps of:
In step S11, the hanger frame 11 is assembled. Referring to fig. 6, after the hanger columns 111 are fixed, diagonal braces 112 and dividing beams 113 may be welded. In other possible embodiments, when the anchor hanger 1 is designed as an anchor hanger unit as described above, the anchor hanger unit may be assembled directly according to the preset position of the anchor 2 or engineering needs.
In step S12, on the hanger frame 11, a single layer of the load-bearing parallel 12 is assembled.
In the above process, the anchor rods 2 are then installed between the stoppers 13 during the assembly of the hanger frame 11. The hanger frame 11 includes multiple layers of load-bearing ties 12, the multiple layers of load-bearing ties 12 being assembled sequentially from bottom to top.
In step S13, the anchor rods 2 are hoisted to the load-bearing flat combination 12 before the next layer of load-bearing flat combination 12 is assembled.
In this step, taking the example of installing a layer of load-bearing parallel bars 12, a first flat beam 121 and a second flat beam 122 are sequentially installed, and a stopper 13, such as a short steel bar, is welded on the first flat beam 121. In other possible embodiments, the connection between the stop 13 and the first flat beam 121 may also be by means of a screw connection. After the limiting pieces 13 are welded, the anchor rods 2 are assembled in sequence, and after the anchor rods 2 of the layer are assembled, the assembly of the bearing parallel connection 12 of the next layer is continued. By means of the sequential assembly mode, the anchor rod 2 can be prevented from being blocked by the bearing parallel connection 12 during installation, and operation time and misoperation rate are reduced.
Referring to fig. 12, on the basis of the above embodiment, the method further includes step S4 and step S5:
In step S4, after the anchor hanger 1 is lifted to a preset position, the anchor 2 is inserted into a hole at the preset position.

The anchor rod hanging frame 1 is lifted to a position where concrete is to be poured, and is placed opposite to the side main beam which is accurately positioned. The constructor inserts single stock 2 or batch with stock 2 to reserve the hole site, and in this in-process, stock gallows 1 can also play the effect of bearing stock 2, the cartridge of stock 2 of being convenient for. This arrangement can prevent the anchor rod 2 from bending in the longitudinal direction due to its own weight.

The hold time for each load remains uniform to achieve a staged load before the load level. And after the tension load is loaded for the maintenance time, the load is unloaded.
Further improved in the above step, the staged tension load is applied with tension loads according to five levels of 10%, 50%, 70%, 100%, 120% of the preset load. Still further, the load is unloaded after 3 minutes of each stage of tensile load. The graded loading load tensioning can enable the stress distribution of the anchor rod 2 to be more uniform, and the prestress loss of the anchor rod 2 can be reduced.
According to the anchor rod hanging bracket 1 disclosed by the invention, through arranging the multi-layer bearing parallel connection 12, a plurality of anchor rods 2 can be placed on each layer of bearing parallel connection 12, so that the anchor rods 2 can be carried and lifted in groups, single anchor rods 2 can be prevented from being carried or lifted independently, the efficiency of carrying and lifting the anchor rods 2 is improved, the repeated mechanical labor is reduced, meanwhile, the bending of the anchor rods 2 caused by dead weight can be avoided, and the service life and performance of the anchor rods 2 are improved.
According to the invention, the inclined struts 112 are arranged on the side surfaces of the anchor rod hanging frame 1, so that the structural strength of the anchor rod hanging frame 1 is enhanced, a certain amount of anchor rods 2 with larger dead weights can be lifted, and the deformation of the anchor rod hanging frame 1 is avoided.
