[0002] During pile or foundation construction, the cage is positioned primarily by lowering it using hanging bars. Generally, the bars are required to be suspended 10 cm above the bottom of the foundation trench behind the hole to ensure the cage remains suspended and centered. Conventional hanging bars are constructed from ordinary threaded steel bars and round steel. The round steel is bent into a circle at the top and welded to the rebar, which is then welded to the main cage bars. Alternatively, a hoist is used to lift the cage from below. These hoists are typically unable to adjust the length of the cage to the desired construction location. Once the concrete has solidified, disassembly and adjustment for stability are difficult.

[0018] Reference Figure 1-3 A steel cage construction hoist comprises a supporting base plate 1, a supporting column 4, a frame assembly and a lifting and pulling assembly. A height-adjusting support plate 2 is provided below both ends of the supporting base plate 1. Four limiting slide bars 21 are provided at the four corners of the height-adjusting support plate 2, and the limiting slide bar 21 movably passes through the supporting base plate 1. A bolt rod 3 is rotatably installed at the center position of the upper surface of the height-adjusting support plate 2, and the bolt rod 3 spirally passes through the supporting base plate 1. A card frame is provided in the middle position of the upper surface of the supporting base plate 1. The bottom end of the supporting column 4 is inserted into the card frame 11, and a slot 41 is provided at the top. The frame assembly comprises an outward-stretching plate 5 symmetrically arranged on both sides and a connecting plate 6 in the middle. The connecting plate 6 is movably inserted into the outer Inside the inner end of the expansion board 5, an insert block 51 is provided below the outer end of the outward expansion board 5, and the insert block 51 is inserted into the slot 41 accordingly. The lifting and pulling assembly includes a connecting block 8, a lifting rope, a roller 7 and a pull ring 61. A roller 7 is provided in the middle position of the lower surface of the outward expansion board 5, and two symmetrical pull rings 61 are provided in the middle position of the lower surface of the connecting plate 6. One end of the lifting rope is tied with a connecting block 8, and the other end passes through the corresponding roller 7 and then passes out from a pull ring 61. The two lifting ropes are tied together after passing through the pull ring 61. Two steel wires are detachably fixed on each of the connecting blocks 8, and the four steel wires on the two connecting blocks 8 are respectively connected to the four corners of the steel cage.

[0019] When the rebar cage needs to be lowered, the support plate 2 is positioned and adjusted, and its surface is treated to make it level (when the two ends of the same support base plate 1 may not be on the same horizontal plane). At this time, the two ends of the support base plate 1 are adjusted to be level by adjusting the rotating bolt rod 3 to ensure that the support column 4 inserted into the clamping frame 11 is placed vertically. The overall length is adjusted by adjusting the depth of the two ends of the connecting plate 6 inserted into the outward slat 5. At this time, the insert block 51 is inserted into the corresponding slot 41 to complete the installation. The rebar cage is lifted to the side of the sling and placed. The four steel wires on the two connecting blocks are tied to the four corners of the rebar cage. The rebar cage is hoisted to the corresponding position and suspended in the air (after the hoisting ropes are combined, they are installed on the winding motor or pulling device, which is a common configuration on construction sites). The rebar cage is lowered to the foundation trench or base, suspended at a certain height, and the length of the hoisting ropes is locked. Cement concrete is then poured (vibration is required to remove bubbles) and waited for solidification. The steel wires on the connecting block 8 are then removed, and the steel wires are left on the poured concrete. After that, the sling is removed and the rebar cage is hoisted to the next location.

[0020] The bottom of the height adjustment support plate 2 is provided with a protrusion array or anti-slip grooves to prevent shaking and slipping during installation.

[0021] The side walls of the card frame 11, the side walls of the slot 41 and the outer wall of the inner end of the outward-stretching plate 5 are all provided with locking bolts, and the connection is locked to prevent falling off or detaching.

[0022] The length of the connecting block 6 is 1.5-1.8 times the length of the outward-stretching plate 5, and a stopper is provided in the middle of the connecting block 6. It can be extended to nearly double the length, and the practical steel cage is wider.

[0023] The connecting block 8 includes a connecting column 81, a locking wire column 82 and a locking bolt 83. The bottom end of the connecting column 81 is fixedly connected to the top end of the locking wire column 82. The locking wire column 82 is provided with a wire through-hole 821. The locking bolt 83 spirally penetrates the side wall of the locking wire column 82 into the wire through-hole 821.

[0024] The lifting rope is passed through the connecting column and tied, and four steel wire ropes of the same length are cut and passed through the steel wire through-hole 821 in a group of two. Then, the locking bolt 83 is screwed inward to squeeze the steel wire to lock the steel wire.

[0025] The frame assembly is made of stainless steel, which has strong stability and tensile strength, and other parts can be made of wood or aluminum alloy frames, which are light.
