Description

File lifting device {Device for sling pile}

The present invention relates to a file lifting mechanism, and more particularly, to a mechanism used when constructing a pile at a construction site or when lifting a pile again.

Generally, in the civil engineering foundation stage, piles are built to support structures, buildings, etc. by putting several piles on the ground.

In addition, in order to construct a pile used in a construction site, it is often necessary to lift a pile in various forms.

For example, when carrying a pile, especially when loading a truck, loading a barge, or unloading the pile in the field, or when the pile is driven to the construction position, the lifting of the pile is essential. The construction and safety are very important for the lifting of such piles.

Various methods, devices, and the like have been proposed for the salvage of such a file, and the most representative method is the hold method.

The hole punching method is a method of tying the upper portion of a pile fixed to the ground in a lasso form using a wire, and then connecting the wire to a hook of a crane to lift.

However, in the case of the punching method, when the diameter of the pile is large or the length of the pile is very difficult to install, it cannot be used, and there is a problem that the pile is damaged locally, such as the deformation of the pile where the wire is bundled. In addition, the anti-corrosive agent applied to prevent corrosion of the pile is peeled off by the wire, thereby reducing the life of the pile due to surface oxidation.

In particular, the knot of the wire is often loosened due to negligence or negligence of the worker, and there is a problem in that the risk of safety accident is very high.

Also, as another method of pile lifting, a hole is fixed on the upper end of the pile, the fixing pin is hooked up, and then connected to the fixing pin using a "U" -shaped hook, the wire in the "U" -shaped hook is hooked to the crane. There is a way to connect to and salvage.

However, this method has a disadvantage in that it is easily damaged when used for a long time due to the pulling force of the crane and the weight of the pile. Therefore, in order to reuse the pile, it is necessary to remove the broken portion and then process the hole again. There are disadvantages in terms of sex and economics.

In addition, another method of pile lifting is to install a plurality of brackets on the top of the pile, and then connect the wire to the hole in the bracket, and then connect the wire to the hook of the crane to lift the pile.

However, this method not only decreases workability because additional work requiring cutting the brackets installed on the file after constructing or lifting the file, but also increases the risk of safety accidents because the worker must work at high altitude. There is a problem.

Therefore, the present invention has been made in view of the above, by lifting the pile at the construction site by implementing a new type of lifting mechanism that can easily and safely lift the pile by coupling the bolt to the top of the pile, The purpose of the present invention is to provide a file lifting device that can increase the efficiency of the file lifting operation and, in particular, minimize the risk of a safety accident during file lifting.

File lifting mechanism provided by the present invention in order to achieve the above object is used to combine the bolt fastening structure to the upper end of the pile when the file is lifted, having a plurality of bolt fastening holes vertically penetrating the top of the pile A ring-shaped assembly in close contact with the support, a plurality of supports extending radially inclined in a downward direction from the bottom of the assembly to the bottom, and radially arranged, a horizontal disc formed at the lower end of each support, and an upper surface of the horizontal disc It is formed in the form having a hook hook portion of the hook formed on the hook of the lifting equipment is formed in the assembly, the bolt fastening hole in the assembly and a bolt in the screw hole at the top of the pile After fastening and engaging, hook the lifting equipment using the hook hanger in the connector. It characterized in that the files to be salvaged.

Here, the combination is to be made of the same size as the ring-shaped cross-section of the pile, and to have a bolt fastening hole corresponding to the position and number of the screw holes of the pile, thereby fixing the reinforcement of the inside of the pile when the pile It is preferable to utilize the existing screw holes provided for connecting the iron plate as it is to be coupled to the pile side.

File lifting mechanism provided by the present invention has the following advantages.

First, because the method of lifting the file by combining the lifting mechanism with the bolt fastening structure on the top of the file, it is easy to lift the file, there is an advantage that can be safely.

Second, since the lifting mechanism can be combined by utilizing the screw holes already formed in the pile, the lifting efficiency can be further improved, such as the lifting operation can be effectively performed without additional processing or attachment of a bracket.

Third, since the lifting mechanism can be coupled and separated by the bolt fastening structure, there is an advantage that can extend the life of the file, such as to prevent damage to the file.

Fourth, because the pile and the lifting device can be easily combined and dismantled at a low position, there is an advantage that can prevent accidents in advance.

Fifth, since the bolt is coupled to the top of the pile, only the fastening bolt can be dismantled and reused after construction, and it is convenient to move quickly to a desired place, allowing for multiple reuses of the pile continuously. There is this.
