Description

Technical Field

[0001] The utility model relates to the technical field of building structure construction, in particular to a device for vertically lifting steel bars. Background Art

[0002] Rebar is the most commonly used material in the construction of building structures. Normally, rebar is lifted horizontally during transportation and transfer. If it is lifted vertically, due to the heavy deadweight of the rebar, multiple rebars are not tied firmly and are easy to fall off. In special cases, vertical lifting can avoid secondary handling. For example, when installing rebars for frame columns of high-rise factories, the installation is often carried out after the support racks are erected. At this time, if the rebar is lifted horizontally, the operator needs to carry it twice and put it vertically into the frame column. If the rebar is lifted vertically, the secondary handling process can be saved and the installation efficiency can be greatly improved. Therefore, a stable device that can lift multiple rebars vertically is needed. Utility Model Content

The bucket 1 is suitable for accommodating a steel bar bundle 5. The steel bar hoop 2 is connected to the outer bottom surface and the outer side surface of the bucket 1 at the same time and extends out of the top of the bucket 1. One end of the connection assembly 3 is suitable for being connected to a lifting hook 6, and the other end of the connection assembly 3 is connected to the steel bar hoop 2. The tying assembly 4 is suitable for tying to the end of the steel bar bundle 5 away from the bucket 1.

[0029] The bucket 1 is fixed by the steel bar hoop 2, thereby improving the strength of the bucket 1, so that the bucket 1 can accommodate one end of the steel bar bundle 5, and at the same time, the steel bar bundle 5 is tied with the end away from the accommodating component by the tying component 4, and finally hoisted by the connecting component 3, so that the steel bar bundle 5 is in a vertical hoisting posture under the action of gravity. The overall structure of the device for vertical lifting of steel bars is simple and the safety factor is high, which improves the construction efficiency of the frame column steel bar installation and avoids secondary transportation.

[0030] In one embodiment, Figure 1 As shown, the steel bar hoop 2 includes a first steel bar 201, a second steel bar 202 and a third steel bar 203. The first steel bar 201 and the second steel bar 202 are arranged along the vertical interval. The first steel bar 201 and the second steel bar 202 are both connected to the outer side of the bucket 1. The third steel bar 203 simultaneously connects the lower end of the first steel bar 201 and the lower end of the second steel bar 202 to form an accommodating space. The bucket 1 is arranged in the accommodating space. The upper end of the first steel bar 201 and the upper end of the second steel bar 202 both extend out of the top of the bucket 1 and are connected to the connecting component 3.

[0031] Specifically, the spacing between the first steel bar 201 and the second steel bar 202 is the same as the maximum outer diameter length of the bucket 1, so that the first steel bar 201 and the second steel bar 202 can more stably clamp the bucket 1, and the force of the connection between the connecting component 3 and the bucket 1 is balanced to prevent the bucket 1 from overturning.

[0032] In one embodiment, Figure 2 As shown, two first steel bars 201, two second steel bars 202 and two third steel bars 203 are provided, the two first steel bars 201 are arranged at intervals, the two second steel bars 202 are arranged at intervals, the two third steel bars 203 are arranged at intervals, one end of the two third steel bars 203 is respectively connected to the lower ends of the two first steel bars 201, and the other ends of the two third steel bars 203 are respectively connected to the lower ends of the two second steel bars 202, the steel bar hoop 2 also includes a first bent steel bar 204 and a second bent steel bar 205, the first bent steel bar 204 is connected to the upper ends of the two first steel bars 201 at the same time, and the second bent steel bar 205 is connected to the upper ends of the two second steel bars 202 at the same time.

[0033] Of course, in other alternative implementations, the first steel bar 201, the second steel bar 202 and the third steel bar 203 can also be provided as one steel bar, as long as the strength requirements are met.

[0034] It should be noted that the first steel bar 201, the second steel bar 202 and the third steel bar 203 are all steel bars that can be found at the construction site, with low cost and high strength. Therefore, the first steel bar 201, the second steel bar 202 and the third steel bar 203 can be set as a plurality of steel bars. By setting a plurality of steel bars, the connection performance between the steel bar hoop 2 and the bucket 1 can be greatly improved without increasing the cost of producing the device for vertical lifting of steel bars.

The tying wire rope 401 and the first wire rope 3021 are connected by the wire rope buckle 403, so as to further fix the steel bar bundle 5, thereby preventing the steel bar bundle 5 from shaking and falling due to environmental factors during the hoisting process, and thus further improving the safety of the construction by using the wire rope buckle 403.

[0044] In one embodiment, the steel bar hoop 2 is welded to the bucket 1. By arranging the steel bar hoop 2 to be welded to the outer bottom surface and the outer side surface of the bucket 1, the strength of the bucket 1 is enhanced, the supporting performance of the bucket 1 is improved, and the service life of the device for vertical lifting of steel bars is enhanced.

[0045] In one embodiment, the first buckle 301 and the second buckle 402 are both U-shaped buckles. The U-shaped buckle has a large buckle retention force, and at the same time, the U-shaped buckle has a U-shaped groove, so that the buckle can be manually moved during disassembly, which is convenient for disassembly.
