Description
The present invention relates to a hook for H beam lifting, and more particularly, a connection part connected to a wire and a pair of support parts mounted on the H beam are integrally formed at an acute angle, and have a structure in which fitting grooves are formed between the support parts. According to the H-beam lifting, the H-beam can be easily and securely grabbed by simply attaching to both ends of the H-beam laid horizontally, thereby lifting the beam safely and safely. It's about hooks.
In general, H-Beam is used as a basis for building structures. The H-beam is a structure in which a pair of horizontal plates are installed orthogonally to both sides of one vertical plate, and is named H-beam because the cross section has an H-shape.
Since H-beam is a foundation of a building structure, it has to have a strong structure, so it is manufactured as a mold and is strong and heavy.
Therefore, when lifting H-Beam for unloading H-Beam, a large crane suitable for lifting heavy items is used. In this case, the hooks are attached to the H-beams by lifting the hooks attached to the H-beams to the wires connected to the crane.
Although not shown in the related art, the hook portion connected to the wire and the rectangular support portion mounted on the inner surface of the horizontal plate of the H-beam are integrally formed in a "c" shape; The support portion has a structure in which a locking device for fixing and releasing the support portion is installed.
Therefore, it is possible to lift the H-beams by operating the crane in a state where the two hooks connected to the wire are mounted on both sides of the upper horizontal plate of the H-beams to be lifted.
In other words, the hook on one side is located on one side of the horizontal plate and the hook on the other side is located on the other side of the horizontal plate on the opposite side, the one side and the other side of the horizontal plate between the connecting portion and the supporting portion of each hook in the locking device Fixing each of the furnace supports is such that the H beam is fixed to the pair of hooks to be lifted.
However, the conventional H-beam lifting hooks having the structure as described above are mounted on the horizontal plates of the H-beams, so that it is not easy to accurately adjust the center of gravity.
Therefore, in order to accurately match the center of gravity, the hook is attached to the H-beams several times, and the locking device must be operated several times each time, so there is a problem that the work of attaching the hook to the H-beam takes a lot of time.
In addition, when lifting the H-beam without precisely centering the center of gravity to shorten the time required for attaching the hook, the H-beam generates an unbalanced load and the H-beam is tilted to one side during the lifting operation, causing unsafe safety accidents. There was also a problem that caused.
The present invention has been invented to solve the above problems, in order to facilitate the work of adjusting the center of gravity of the H-beam when attaching the hook to the H-beam to quickly and safely lifting the H-beam, A connecting portion formed at the end of the connecting hole for connecting to the wire and a pair of supporting portions mounted on the inner surface of the horizontal plate of the H-beam are integrally formed at an acute angle with each other; An accommodating space is formed between the connecting portion and the supporting portion to closely accommodate the side portion of the horizontal plate of the H-beam; It is composed of a structure in which the insertion groove is inserted between the support portion is inserted into the vertical plate of the H-beam; It is an object of the present invention to provide a hook for an H beam lifting.
The hook for the H-beam lifting of the present invention can not only make the mounting work on the H-beam more quickly, but also can accurately match the center of gravity of the H-beam at once, thereby reducing the time required for the lifting operation of the H-beam. It can be greatly shortened, the H-beams do not generate an unbalanced load is lifted with a sense of stability, there is an effect that can safely carry out the lifting operation of the H-beams.
Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.
1 is a perspective view of the present invention of the present invention, Figure 2 is a state diagram used in the present invention.
In the H-beam lifting hook 100 of the present invention in the configuration of the hook to lift the H-beam (H) through the structure attached to the H-beam (H) in the state connected to the wire (W) connected to the crane in The connecting portion 2 formed at the end of the connecting hole 1 for connecting to the wire W, and the pair of supporting portions 3 mounted on the inner surface of the horizontal plate A of the H beam H It is formed integrally at an acute angle with each other in the state having a receiving space (4) for accommodating the side portion of the horizontal plate (A) of the beam (H); It is composed of a structure in which the insertion groove (5) is inserted between the support portion (3) of the vertical plate (B) of the H beam (H); It features.
H beam lifting hook 100 of the present invention configured as described above is a type of clamp used when lifting the H beam (H) that is the basis of the building structure, is connected to the wire (W) connected to the crane using the H It is a tool attached to the beam H.
In particular, the H-beam lifting hook 100 of the present invention provides a structure that can be easily fitted to fit the center of gravity of the H-beam (H) when mounted on the H-beam (H) by lifting the H-beam (H) The main feature is that the work can be done more quickly and safely.
As shown in FIG. 1, the connecting portion 2 connected to the wire W and the pair of supporting portions 3 mounted on the H beam H are integrally formed at an acute angle with each other, and the connecting portion ( A receiving space 4 is formed between 2) and the supporting part 3 so that the side surface portion of the horizontal plate A of the H beam H is in close contact with each other, and the number of the H beams H is between the supporting part 3. It is due to the insertion groove 5 is formed that the straight plate (B) is inserted.
That is, the hook 100 is due to the structure that can be attached to both ends of the H-beam (H) in the horizontal lying state.
Therefore, when attaching the hooks 100 on both sides connected to the wires W to lift the H beams H, respectively, the hooks 100 on both sides are connected to both ends of the H beams H, respectively. Just attach and install.
At this time, a side portion of the horizontal plate A of the H beam H is inserted into the accommodation space 4 formed between the connecting portion 2 of the hook 100 and the supporting portion 3, and the supporting portion 3 of the hook 100 is inserted into the receiving space 4. In order to support the inner surface of the horizontal plate (A) and at the same time insert the vertical plate (B) of the H beam (H) into the insertion groove (5) formed between the support portion (3) of the hook (100).
Then, as shown in FIG. 2, the hooks 100 on both sides are fitted to the left and right centers of both ends of the H beam H, respectively, so that the center of gravity of the H beam H can be precisely adjusted.
Accordingly, in order to accurately match the center of gravity of the H beam H, the hook 100 may be repeatedly mounted to the H beam H several times. Unlike the conventional method, the center of gravity of the H beam H only once By being able to accurately fit in as it is possible to quickly the mounting work of the hook (100).
In addition, it is not easy to adjust the center of gravity can be solved the problem that the conventional hook that caused a safety accident caused by the load on the lifting H beam (H).
When the H beam H is lifted, the support part 3 supporting the inner surface portion of the horizontal plate A of the H beam H is inserted into the horizontal plate A with the vertical plate B in the center. While being in an acute state with the connection part 2, there is no fear that the hook 100 may fall out of the H beam H.
Accordingly, after attaching the hook 100 to the H beam H, the hook 100 is fixed to the H beam H by a separate locking device. Once attached to the hook 100 is firmly fixed to the H beam (H) it is possible to eliminate the inconvenience and inconvenience of the conventional due to the locking device.
