Description

A combined spreader for I-beam hoisting

technical field

The utility model relates to the technical field of hoisting construction, in particular to a combined hanger for hoisting I-beams.

Background technique

I-beam is a steel used in large quantities in the construction of buildings, bridges and tunnels. During the construction process, it is often necessary to hoist the I-beam to the construction point, which is convenient for the construction personnel to weld and assemble the I-beam, thus forming the building skeleton support. However, according to different construction requirements, the size of the I-beam used is also different, so the hoisting hook is subject to the size limitations of the I-beam, and the I-beam hangers in the prior art are mostly clamp hooks. The I-beam is clamped on both sides of the extension direction of the I-beam, and the I-beam is hoisted by connecting the hook of the hoist to the I-beam. However, this hoisting method has great safety risks, and the I-beam is easily affected by wind resistance and other external factors during the hoisting process. There is relative sliding with the fixture hook. Even if multiple fixture hooks are set to maintain balance and keep the I-beam in a horizontal state during the hoisting process, this hoisting method still cannot solve the problem of the I-beam sliding in its extension direction.

Through a public patent search, the following comparative documents were found:

An I-beam hanger (CN108609483A) discloses an I-beam hanger, comprising a first hook and a second hook, the first hook and the second hook are movably connected, and the first hook is movably connected. The side wall is provided with a plug, and the inside of the second hook is provided with a slot matched with the plug. By arranging a latch on the first hook and a latch on the second hook, the active connection between the two hooks is realized, so as to adjust the clamping distance between the two hooks, which can be used for clamping different hooks. Specifications of I-beam.

After analysis, it is found that the above-mentioned published patent is different from the present application in terms of I-beam hoisting force application position and safe release structure, etc., so it does not affect the novelty of the present application.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the prior art, and to provide a combined spreader for I-beam hoisting, the combined spreader is hoisted at both ends of the I-beam, so that the spreader is no longer affected by the I-beam. The size is affected, and the problem of the I-beam sliding in its extension direction is effectively avoided, and the safety strap is installed to effectively avoid the loosening of the spreader, which improves the safety factor of hoisting. It has a simple structure and low cost, and is widely used in various models. I-beam hoisting construction.

A combined hoisting tool for I-beam hoisting comprises resistance hooks oppositely hung on both ends of the I-beam and a safety pull belt connecting the two resistance hooks; the resistance hook comprises a bottom plate and a hook plate, wherein one end in the middle of the bottom plate is made The slot is inserted into the I-beam vertical plate, and the other end of the middle part of the bottom plate is fixed with a hook plate arranged obliquely upward; the middle part of the hook plate is made with a safety hole that passes through horizontally, and the top of the hook plate is made with a horizontal through hole. hoisting holes.

Moreover, both ends of the safety belt are respectively penetrated and wound in the safety hole.

Moreover, rubber pads are compositely bonded on the top surfaces of the bottom plates on both sides of the slot.

The advantages and technical effects of the present utility model are:

The utility model is a combination hoisting tool for hoisting I-beams. The I-beams are hoisted through the resistance hooks that are clamped at both ends of the I-beams. The design makes the hoisting construction of the I-beams no longer affected by the length of the I-beams themselves. It is not limited by the size of the spreader, and is widely used in the hoisting construction of various types of I-beams; the two resistance hooks are wound and fixed by the safety pull belt to avoid the vibration of the I-beam due to factors such as high-altitude wind resistance. , and then cause the two resistance hooks to slide back and cause the I-beam to loosen; increase the frictional resistance between the top surface of the resistance hook bottom plate and the bottom surface of the I-beam top horizontal plate through the rubber pad, improve the safety factor of hoisting, and the bottom plate can be inserted through the slot. Connected to the vertical plates on the two ends of the I-beam, it can effectively avoid the torsional sliding of the hook and the end surface of the I-beam during the hoisting process, and improve the hoisting stability. Finally, the hoist hook is connected through the hoisting hole, and the hoisting is symmetrically hoisted in a tilt-to-pull manner. At both ends of the I-beam, the horizontal hoisting of the I-beam can be ensured, which effectively avoids the problem of relative sliding between the I-beam and the hook.

The utility model is a combined hanger for hoisting I-beams, which has the advantages of simple structure, convenient use, easy disassembly and adjustment of safety pull belts, and easy insertion and removal of resistance hooks. The problem of relative sliding with the hook is a highly creative combination spreader for I-beam hoisting.
