Technical Field

[0001] The utility model relates to a building cable construction structure, in particular to a construction structure for installing cables at a building top plate. Background Art

[0002] During construction, when installing and threading cables at the top of a floor, due to the high floor height, thick cable diameter and heavy weight of long cables, it is difficult for workers to lift and pull the cables, making cable installation difficult.

[0003] Chinese patent document CN2847618Y discloses a cable tray reinforcement connection member that uses a connector to connect a bracket arm to a fixed wall through a fixed implant. The fixed implant forms a slideway and is fixed to the building using concrete pouring. The device is set according to the length of the laid cable. However, the patent has the disadvantage that it only fixes the cable to the building, and the time required to re-install the cable does not alleviate the difficulty of workers lifting and pulling the cable, making cable installation difficult.

[0004] In view of this, the present utility model is applied for. Utility Model Content

[0005] The utility model provides a high-altitude cable installation pulley machine used in building construction, so as to solve the problems of great difficulty for workers in lifting and pulling cables and difficulty in cable installation during cable installation construction at the top plate of a building.

[0006] In order to solve the above problems, the utility model provides a high-altitude cable installation pulley machine used in construction, including a building beam 1, and also including embedded parts 2, anchor plates 3, anchor rings 4 and pulley bracket assembly 5; embedded parts 2 are embedded at intervals on the building beam 1, and the embedded parts 2 fix the anchor plates 3 to the outside of the building beam 1, and anchor rings 4 are welded on the anchor plates 3; the lower part of the pulley bracket assembly 5 is a pulley bracket 52, and a hook 51 is fixed above the pulley bracket 52, and a pulley 53 with a horizontally arranged axis is arranged between the two side plates of the pulley bracket 52, and the two ends of the rotating shaft of the pulley 53 are arranged in the shaft holes of the side plates, and the nuts on the outer sides of the left and right side plates are connected to the outer ends of the rotating shaft, and the pulley 53 forms a rotational matching relationship with the rotating shaft.

[0007] Furthermore, the high-altitude cable installation pulley machine used in construction of the present invention also has the following characteristics: the anchor plate 3 is a square structure, each anchor plate 3 has holes at the four corners, each group of embedded parts 2 has four, four embedded parts 2 pass through the holes of one anchor plate 3, and the nut at the outer end of the anchor plate 3 is connected to the external thread at the outer end of the embedded part 2 to fix the anchor plate 3 and the embedded part 2 together.

[0008] Furthermore, the overhead cable installation pulley machine used in construction of the present invention also has the following characteristics: the anchor ring 4 is a U-shaped structure, and both ends of the U are welded to the anchor plate 3.

[0009] Furthermore, the overhead cable installation pulley machine used in construction of the present invention also has the following characteristics: the pulley bracket 52 is a semi-frame structure consisting of left and right side panels and a top.

[0010] Technical effects of this utility model:

[0011] The cable is passed through the pulley of the pulley bracket assembly at the required position according to the construction location, so that when workers pull the cable during construction, the cable moves smoothly on the pulley, reducing the labor intensity of the workers and facilitating cable installation.

[0012] During the main structure construction, embedded parts and anchor plates are placed on the side of the beam. Before the cables are installed, anchor rings are welded to the anchor plates and the pulley bracket system is hung on the anchor rings via hooks. The overall structure is simple and easy to install.

[0013] During the construction of thick cables, the cables are passed through the upper side of the pulley, and workers place the cables in the designated position by pulling them. This construction method effectively guarantees the construction period, reduces the labor intensity of workers, ensures the installation quality, reduces the construction cost, and achieves a good overall construction effect.

[0014] After construction and installation, the anchor plate can be removed by removing the nut, and the pulley bracket assembly can be removed by using a hook, thereby achieving a high component reuse rate and saving costs and materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is described in detail with reference to the best embodiment below.

[0020] like Figure 1-3As shown, a pulley machine for installing an aerial cable used in construction includes a building beam 1, embedded parts 2, anchor plates 3, anchor rings 4, and a pulley bracket assembly 5. Embedded parts 2 are embedded at intervals on the building beam 1, securing the anchor plates 3 to the outside of the building beam 1. Embedded parts 2 can be screws. The anchor plates 3 are square in shape, with holes at the four corners. Each set of embedded parts 2 has four embedded parts 2, with four embedded parts 2 inserted through the holes in each anchor plate 3. Nuts on the outer ends of the anchor plates 3 connect to the external threads on the outer ends of the embedded parts 2, securing the anchor plates 3 and the embedded parts 2 together. Anchor rings 4 are welded to the anchor plates 3. The anchor rings 4 are U-shaped, with both ends welded to the anchor plates 3.

[0021] The lower portion of the pulley bracket assembly 5 is the pulley bracket 52. The pulley bracket 52 is a semi-frame structure consisting of left and right side panels and a top. A hook 51 is fixed above the pulley bracket 52. The lower end of the hook 51 passes through the top panel of the pulley bracket 52. The threaded body at the lower end of the hook 51 is connected to a nut, thereby fixing the pulley bracket 52 and the hook 51 together. A pulley 53 with a horizontal axis is set between the two side panels of the pulley bracket 52. The ends of the rotating shaft at the center of the pulley 53 are set in the shaft holes of the side panels. The nuts on the outer sides of the left and right side panels are connected to the outer ends of the rotating shaft, thereby mounting the pulley 53 on the pulley bracket 52. The pulley 53 and the rotating shaft form a rotational fit.
