[0002] A precast column is a component in a prefabricated building, composed of reinforced concrete. Each precast column will have part of the steel bars reserved and exposed outside for connecting other precast columns or precast slabs. There are various styles of precast columns on the market currently.
[0003] However, as disclosed in the utility model patent with the authorization announcement number CN210622110U, a precast column convenient for handling is provided, including a precast column main body. A first protection device is sleeved and installed outside one end of the precast column main body, and a second protection device is sleeved and installed outside the other end of the precast column main body. A reserved steel bar is fixedly installed at one end of the precast column main body. The first protection device includes a connecting frame and a movable plate. A fixing screw hole is opened on the upper surface of the connecting frame. A fixing bolt passes through the upper part of the movable plate. A convex block is fixedly installed at the middle position of the lower part of the movable plate. A groove is opened on the lower surface of the connecting frame. A roller is arranged inside the groove. A connecting shaft is connected between both ends of the roller and the groove. The width of the first protection device is equal to twice the length of the reserved steel bar. The precast column convenient for handling described in the utility model can protect the reserved steel bar from being bent, and at the same time, it is convenient for people to carry the precast column main body.

The reserved steel bar is not docked with the protection device, resulting in the outer end of the reserved steel bar still being touched and damaged. Moreover, the position of the movable plate on the connecting frame is limited by the fixing screw hole and the fixing bolt, but the operation is troublesome and time-consuming. At the same time, after the main body is inside the protection device, the lower end of the main body is in a suspended state and is prone to bending and damage when being collided. Therefore, we propose a precast column capable of quickly docking steel bars to solve the problems raised above. Content of the Utility Model

[0031] Please refer to Figure 1-6 , the present invention provides a technical solution: a precast column capable of quickly docking steel bars, including a main body 1, reserved steel bars 2, a connection groove 3, a connection platform 4, a protection frame 5, a protection plate 6, a connection strip 7, a limiting strip 8, a connection ear 9, a mounting plate 10, a threaded rod 11, a connection plate 12, a guiding rod 13, a bearing plate 14, a limiting rod 15 and a limiting groove 16.
[0032] Embodiment 1: In the prior art, the position of the movable plate on the connection frame is limited by fixing screw holes and fixing bolts, but it is more troublesome and time-consuming during operation. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 3 and Figure 4 , since the handling structure includes a protection frame 5, a protection plate 6, a connection strip 7, a limiting strip 8 and a connection ear 9, the protection plate 6 with a longitudinal section in a "convex" shape is snap-connected to the inner part of the upper end of the protection frame 5. The limiting strip 8 is nested and connected inside the connection ear 9. Connection strips 7 are rotatably connected to the front and rear ends of the protection plate 6. Therefore, the protection frame 5 is respectively placed on the left and right sides of the main body 1, and the left and right ends of the main body 1 are respectively snap-connected to the inside of the protection frame 5 from the upper end of the protection frame 5. The protection plate 6 with a longitudinal section in a "convex" shape is snap-connected to the inner part of the upper end of the protection frame 5 with a longitudinal section in a "concave" shape on the left side when viewed longitudinally. The symmetrically arranged connection strips 7 at the front and rear are respectively rotated, and the limiting strip 8 is nested and connected inside the connection ear 9 at the corresponding position. The position of the protection plate 6 on the protection frame 5 is limited by the connection strip 7, the limiting strip 8 and the connection ear 9, so as to facilitate handling and quickly install the handling structure on the precast column;
[0033] Embodiment 2: Although the existing reserved steel bars 2 are within the first protection device and the second protection device, the first protection device and the second protection device do not fully protect the reserved steel bars 2, and the reserved steel bars 2 are not connected to the protection device, resulting in the outer ends of the reserved steel bars 2 still being touched and damaged. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 , Figure 2 and Figure 6 , since the protection structure includes a connection groove 3, a connection platform 4, a mounting plate 10, a threaded rod 11, a connection plate 12 and a guide rod 13, the connection grooves 3 are equally spaced and opened at the inner end of the connection platform 4, the connection platform 4 is snap-connected to the inner part of the outer end of the protection frame 5, the threaded rod 11 is threadedly connected to the rear end of the mounting plate 10, the connection platform 4 is snap-connected to the inner part of the outer end of the protection frame 5, and the mounting plate 10 is in a sliding structure on the outside of the protection frame 5 through the threaded rod 11 and the guide rod 13. Therefore, rotate the threaded rod 11 respectively to rotate it on the rear connection plate 12, so that the front side of the mounting plate 10 moves inward on the guide rod 13. Through the threaded rod 11 and the guide rod 13, the mounting plate 10 drives the connection platform 4 to stably approach the protection frame 5 until the inner end of the connection platform 4 is snap-connected to the inner part of the outer end of the protection frame 5, and the equally spaced connection grooves 3 are nested on the reserved steel bars 2 until the inner end of the connection platform 4 abuts against the outer end of the main body 1, so that the reserved steel bars 2 are docked in the corresponding connection grooves 3, thus being able to quickly dock the reserved steel bars 2 and prevent the reserved steel bars 2 from being bent;
[0034] Embodiment 3: After the existing main body 1 is placed in the protection device, the lower end of the main body 1 is in a suspended state and is easily bent and damaged when being collided. Therefore, in this embodiment, through the following technical solutions, such as Figure 1 and Figure 5 , since the left and right ends of the bearing plate 14 are fixedly connected with limiting rods 15 symmetrically in the front and rear directions, the outer ends of the limiting rods 15 are snap-connected to the inside of the limiting grooves 16, and the positions of the limiting grooves 16 correspond to the positions of the limiting rods 15 one by one in the left and right directions. Therefore, place the main body 1 on the upper end of the bearing plate 14. When the left and right two groups of protection frames 5 approach the left and right ends of the main body 1, the symmetrically arranged limiting grooves 16 in the front and rear directions are snap-connected to the limiting rods 15 at the corresponding positions, so that the left and right ends of the bearing plate 14 are in contact with the inner ends of the protection frames 5, and the bearing plate 14 supports the main body 1, thus facilitating the protection of the precast column.
