Description

Technical Field

[0001] This utility model belongs to the field of steel bar hoisting technology, specifically relating to a confined space steel bar hoisting and conversion component device. Background Technology

[0002] Steel structure factory floor slabs typically use reinforced steel truss floor slabs or profiled steel sheet floor slabs. This requires laying continuous reinforcing bars on-site, then hoisting bundles of long bars directly onto the floor slab before proceeding with reinforcement installation. Traditional methods for hoisting bundles of long reinforcing bars onto the floor slab only have two lifting points. The long bars are prone to bending in the middle and at both ends, posing a risk of slipping and detachment. When the lifting point is closer to the middle, the bending at both ends is greater; when the lifting point is closer to the ends, the bending in the middle is greater, both easily leading to slippage. This is even more difficult when hoisting reinforcing bars in confined spaces. Taking steel structure projects as an example, with the left and right steel columns and upper and lower steel beams already installed, and the floor slabs often using reinforced steel truss floor slabs or profiled steel sheet floor slabs, hoisting bundles of long reinforcing bars onto the floor slab is limited by the vertical and horizontal space. Repeated adjustments to the angle and height are necessary to lift the bars onto the floor slab. During hoisting, the bars are highly susceptible to collision with the steel columns, resulting in low hoisting efficiency and high safety risks. Summary of the Invention

[0003] The purpose of this utility model is to provide a confined space steel bar hoisting and conversion component device, which solves the problems of steel bars being easily deformed and slipping during traditional hoisting by increasing the number of hoisting points.

[0004] To achieve the above objectives, this utility model is implemented through the following solution: A confined space rebar hoisting and conversion component device includes a hanging beam, a hanging assembly, and a connecting assembly. The hanging assembly is disposed on the hanging beam for suspending rebar, and the connecting assembly is disposed between the hanging beams for connecting two adjacent hanging beams. The connecting assembly includes a connecting plate and a connecting bolt. The connecting plate is connected to two adjacent hanging beams to connect the two adjacent hanging beams together, and the connecting bolt is used to connect the hanging beam and the connecting plate.

[0005] Furthermore, the connecting plate includes a wing plate connecting plate and a web plate connecting plate. The wing plate connecting plate is disposed on the wing plate of the suspension beam and includes an outer connecting plate and an inner connecting plate. The outer connecting plate is disposed on the outer surface of the wing plate, and the inner connecting plate is disposed on the inner surface of the wing plate. The web plate connecting plates are disposed opposite to each other on both sides of the web plate of the suspension beam.

[0006] Furthermore, the suspension assembly includes a hook, a suspension rope, an upper lifting lug, a lower lifting lug, and a connecting plate. The upper lifting lug is disposed on the upper flange of the suspension beam and is arranged in groups. The hook is connected to the upper lifting lug via the suspension rope. The lower lifting lug is disposed on the lower flange of the suspension beam and is connected to the binding rope for tying reinforcing bars. The connecting plate is disposed on the web of the suspension beam and is arranged corresponding to the lower lifting lug.

[0007] Furthermore, the hook is a swivel hook.

[0008] Furthermore, the angle between the lifting rope connected to the upper lifting lug and the wing plate of the hanging beam is 45° to 60°.

[0009] Furthermore, multiple lower lifting lugs are provided at intervals, and the lower lifting lugs are symmetrically welded at the bottom of the suspension beam every 2m to 2.5m.

[0010] Furthermore, the gusset plates are symmetrically arranged on both sides of the web of the suspension beam.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-3 This utility model provides a confined space rebar hoisting and conversion component device, including a hanging beam 1, a hanging assembly 2, and a connecting assembly 3. The hanging assembly 2 is mounted on the hanging beam 1 and is used to hoist rebar 4. The hanging beam 1 can be made of I-beams, H-beams, etc. The hanging assembly 2 includes a hook 201, a lifting rope 202, an upper lifting lug 203, a lower lifting lug 204, and a connecting plate 205. The upper lifting lugs 203 are fixed in groups to the upper flange of the hanging beam 1. The hook 201 is connected to the upper lifting lug 203 through the lifting rope 202. The hook 201 is a rotating hook, which facilitates the adjustment of the hoisting direction of the hook 201 in the confined space. The angle between the lifting rope 202 connected to the lug 203 and the upper flange of the suspension beam 1 is 45° to 60° to ensure the stability of the center of gravity during suspension. The lower lifting lug 204 is set on the lower flange of the suspension beam 1 and is connected to the binding rope of the reinforcing bar 4. The binding rope is made of flexible material, which can increase the flexibility protection when in contact with the bundled reinforcing bars 4 and reduce the wear on the lifting strap. The lower lifting lug 204 is symmetrically welded at the bottom of the suspension beam 1 every 2m to 2.5m. The lacing plate 205 is welded to the web of the suspension beam 1 and is set corresponding to the lower lifting lug 204. The lacing plate 205 is symmetrically set on both sides of the web of the suspension beam 1.

[0018] The length of the hanging beam 1 should be similar to the length of the reinforcing bar 4 to be hung. If the length of the hanging beam 1 is short, two hanging beams 1 can be connected by a connecting assembly 3. The connecting assembly 3 includes a connecting plate 301 and a connecting bolt 302. The connecting plate 301 connects to two adjacent hanging beams 1 to connect them together. The connecting bolt 302 connects the hanging beam 1 and the connecting plate 301. The connecting bolt 302 can be in the form of a bolt + nut + washer. The bolt connects the connecting plate 301 to the hanging beam 1, and the nut is on both sides of the bolt. The end is threaded with a bolt, and a washer is placed between the nut and the hanging beam 1. The connecting plate 301 includes a wing plate connecting plate 3011 and a web plate connecting plate 3012. The wing plate connecting plate 3011 is placed on the wing plate of the hanging beam 1 and includes an outer connecting plate and an inner connecting plate. The outer connecting plate is placed on the outer surface of the wing plate, and the inner connecting plate is placed on the inner surface of the wing plate. The web plate connecting plate 3012 is placed on both sides of the web plate of the hanging beam 1. The wing plate connecting plate 3011 has the same width as the wing plate, and the web plate connecting plate 3012 has the same width as the web plate.

[0019] During on-site construction, the hanging beam 1 can be made of 10# I-beams, and its length should be close to that of the bundled steel bars 4. To accommodate the hoisting of bundled steel bars 4 of different lengths, the I-beams can be assembled from two lengths. For example, a 9m long steel bar can be hoisted using a single 9m long 10# I-beam with a welding lug, or a 6m long + 3m long I-beam can be assembled using connecting components 3. A 12m long steel bar can be assembled using two 6m long 10# I-beams (or a 9m long + 3m long) using connecting components. The lifting lugs can be welded from 12mm diameter round steel, and the thickness of the gusset plate 205 can be the same as the thickness of the steel at the corresponding position of the hanging beam 1. The connecting bolts 302 in the connecting components can be connected using ordinary bolts such as M10 and M12.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
