Embodiment 1

[0046] A kind of jig for hoisting and transporting H-shaped steel beams of the present embodiment, such as figure 1 , 2 As shown, it includes a steel wire rope 3 and lifting clamps 2 symmetrically distributed on the H-shaped steel beam 1; the lifting clamp 2 is in the shape of a rectangular opening hook, including a lifting hole 21 and a card slot 23 connected as one with the hook end. 24; the clamping groove 23 fits the shape and thickness of the far end 11 of the steel beam flange plate on both sides of the H-shaped steel beam 1, is clipped to the far end 11 of the steel beam flange plate, and passes through the hoisting hole 21 and the steel wire rope branch 31 of the steel wire rope 3 The hooking end 24 cooperates with the card slot 23 and fastens to the bottom of the far end 11 of the flange plate of the steel beam.

Embodiment 2

[0049] A fixture for hoisting H-shaped steel girders in this embodiment has the same basic structure as in Embodiment 1, and the improvement is that evenly distributed hook grooves 241 are arranged on the upper surface of the hook end 24 to improve the height of the lifting clamp. Tool 2 is hook-holding adhesion to the H-shaped steel girder 1. There are even pairs of hoisting fixtures 2, which can be buckled symmetrically, and can be applied in an adaptive quantity according to the specifications of the H-shaped steel beam 1. For example, if the length is 6m, at least 3 pairs of hoisting fixtures 2 need to be laid out, symmetrically and evenly buckled. The far end 11 of the steel beam flange plate on both sides of the H-shaped steel beam 1; the steel material of Q345C is selected for use by the hoisting clamp 2, which is easy to obtain materials, convenient to manufacture, and can also reuse waste.

Embodiment 3

[0057] A kind of double-hook fixture for hoisting and transporting H-shaped steel beams of the present embodiment, such as image 3 , 4 As shown, it includes a steel wire rope 3 and a hoisting fixture 2 hung on both ends of the H-shaped steel beam 1; the hoisting fixture 2 is a double V-shaped hook, and the bottom is two hooking ends 24, and the double V-shaped hook passes through The hoisting connection part 22 is connected as a whole, and the steel wire rope sub-strands 31 of the steel wire rope 3 are connected to the hoisting connection part 22 .

[0058] A double-hook fixture for hoisting H-shaped steel girders in this embodiment is applied to the lifting of H-shaped steel girders 1. For relatively short lengths, such as less than 1 m, and heights of less than 500 mm, such as H400 or 300 or 150 mm, etc., The H-shaped steel girder 1 with a relatively large width is convenient for hooking from both ends. Combined with the structural characteristics of the symmetrical steel ...

Abstract

The invention discloses a clamping apparatus for lifting an H-shaped steel beam and a lifting method thereof, and belongs to the technical field of building construction equipment. The clamping apparatus for lifting the H-shaped steel beam is applied to lifting of the H-shaped steel beam and comprises a steel wire rope and lifting clamping apparatus bodies symmetrically distributed on the H-shapedsteel beam, each lifting clamping apparatus body is in a rectangular opening hook shape, and comprises a lifting hole, a clamping groove and a hooking end, and the clamping groove and the hooking endare connected into a whole; the clamping grooves are wedged with shapes and thicknesses of far ends of steel beam flange plates on the two sides of the H-shaped steel beam, are clamped to the far ends of the steel beam flange plates, and are connected with steel wire rope strands of the steel wire rope through the lifting holes, and the hooking ends are matched with the clamping grooves to be tightly buckled on the bottoms of the far ends of the steel beam flange plates. Through the symmetrically-distributed lifting clamping apparatus bodies in the rectangular opening hook shape, the H-shapedsteel beam is clamped, lifting is carried out through the steel wire rope, operation is flexible, lifting efficiency is high, and time and labor are saved. The problems that in the prior art, the H-shaped steel beam wastes time and labor in lifting, and maneuverability is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a clamp for hoisting H-shaped steel girders and a hoisting method thereof. Background technique [0002] For the installation of steel structure engineering, there are some H-shaped steel girder components produced and installed, that is, the unloading and installation of a large number of H-shaped steel girder components, the fixtures are used frequently and in large quantities. In practice, the equipped standard jigs are often expensive, so that the quantity is limited, and the operation requirements are high, which affects work efficiency. [0003] There are many types of cards currently on the market, which can be roughly divided into three categories: chain spreaders, clamp spreaders and lifting suction cups. Chain spreaders are widely used in the field of construction production and construction. According to The object to be lifted need...
