Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a steel beam lifting lug which does not require welding. Background Art

[0002] With the rapid development of my country's construction industry, steel structures have gradually been widely used in various construction fields due to their advantages such as low comprehensive cost, good seismic performance and short construction period.

[0003] Steel frame buildings are a common structural form. In order to facilitate lifting, lifting ears are usually welded on both ends of the steel beam. When lifting, the shackles are inserted into the lifting ears, and the steel beam is lifted to the designated position before installation. After the steel beam is installed in place, the lifting ears need to be cut off and polished to ensure the safety of workers walking on the steel beam and the flatness of the floor deck.

[0004] During this process, the layout and cutting of the lifting ears, welding in the processing plant, shot blasting and rust removal, paint spraying, on-site cutting, paint spotting and other tasks are involved; and each steel beam requires two lifting ears, and the ears cannot be reused after being cut off, and the cut ears can only be treated as scrap steel. Utility Model Content

[0005] The utility model aims to overcome the above defects and provides a steel beam lifting eye which does not require welding, can be recycled and does not require hot work.

[0006] In order to achieve the above object, the utility model is achieved as follows:

[0007] A steel beam lifting lug that does not require welding comprises a lifting lug body (1) with a side projection of an inverted "T" shape, a clamp (2) with a side projection of a "C" shape, an anti-drop lock (3), a sleeve (4) and a clamping bolt (5); the lifting lug body (1) with a side projection of an inverted "T" shape is assembled and welded by a steel plate and an ear plate, and a lifting hole is arranged on the top to ensure the normal insertion and use of a tower crane shackle; the clamp (2) with a side projection of a "C" shape is assembled and welded by a steel plate, and a hole is opened at the top to facilitate sleeve welding; the anti-drop lock (3) uses a lock to connect the lifting lug and the clamp; the sleeve (4) uses a full-thread sleeve, which is vertically fixed to one end of the load-bearing lifting lug body (1), and the bottom is flush with the lifting lug body (1); there are four clamping bolts (5), all of which are full-thread bolts, and the clamping bolts (5) pass through the lifting lug body (1) and the clamp (2) to tighten the lifting lug body (1) on the steel beam.

[0008] The steel beam lifting eye that does not require welding has a long hole on the steel plate of the lifting eye body (1) for arranging a clamping bolt (5).

[0009] The anti-drop lock (3) of the steel beam lifting lug that does not require welding is a flexible lock. Connecting holes are opened on the ear plate of the lifting lug body (1) and the clamp. The anti-drop lock (3) passes through the ear plate of the lifting lug body (1) and the connecting holes of the clamps (2) on both sides in sequence, thereby connecting the lifting lug body (1) and the clamps (2) together to prevent loss and falling from a high altitude.

[0010] The above-mentioned steel beam lifting lug proposed in the utility model has the following advantages:

[0011] 1. Simple installation, easy to use, and can quickly hoist steel beams after mastering it;

[0012] 2. The lifting lugs can be recycled after being removed through this lifting lug construction method, thus reducing the amount of steel used for the lifting lugs;

[0013] 3. Save labor and materials, no need to cut and grind on site. BRIEF DESCRIPTION OF THE DRAWINGS
