Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety support apparatus for connecting a file using a connector and a bolt,

The present invention relates to an apparatus and method for connecting upper and lower files by using connectors and bolts, and more particularly, to an apparatus and a method for connecting a file and a bolt, The present invention relates to a safety support apparatus for connecting a file.

Generally, a soft ground such as soft clay, loose sand or organic soil can not withstand the load from the superstructure itself or the predicted settlement exceeds the allowable limit. It is necessary to use the ground formed by the landfill as the basis of the road or the building in recent years as well as a problem of safety due to lack of bearing capacity, , It is expected that excessive settlement and lack of bearing capacity will be required even in these grounds, and measures for treating soft ground are required.

Among the countermeasures against the stability and settling problems at the time of constructing the structure based on the soft ground as described above, the embankment load is commonly used to reach the support layer (PILE utilization method) After thoroughly examining the size and soil quality of existing concrete piles such as PEI, PC, and AL, construction will be done by the type construction method (hitting, vibration) or the purchase method.

In particular, the PHC (Pretensioned Spun High Strength Concrete Piles) is a high strength pile made of a pre-tensioned concrete having a compressive strength of 78.5 N / mm 2 (800 Kgf / cm 2) Is very large and can withstand a greater axial load than a conventional PC file. It is also excellent in impact resistance by uniformly introducing a required prestress to a section formed by concrete having a compressive strength of 800 Kgf / , Because it fully absorbs the tensile stress caused by the reflected waves generated during hunting, it can be penetrated into a deeper and harder layer because there is no crack, and a hard intermediate layer which is difficult to be hammered by a conventional PC file is easily penetrated, Since the flexural tensile stress of concrete is large, it is the most suitable file for seismic design that receives both axial force and horizontal force. .

In the case of deep installation according to the scale of the building to be constructed and the geological condition of the building, it is necessary to prevent the eccentricity from occurring by connecting a plurality of PE files to each other by tightly connecting the PE files. A joint cap or a joint shoe was installed at each of the upper and lower ends and welded together or fastened with bolts and nuts was used.

Usually, the method of connecting two files is to insert the file to be connected to the head of the constructed file first with a crane or the like, while exposing the head of the file to be inserted into the ground at the beginning and exposing the head of the file to the ground.

However, when connecting the two files, if the axis of the upper file does not coincide with the axis of the lower file, it is preferable that the upper file is correctly aligned with the lower file because the outer diameters of the two files are misaligned.

For example, as shown in FIG. 5, the upper concrete file F2 is lifted up using a crane, and then vertically arranged on the lower file F1, and the joints of the two files are welded. However, In order to align the outer diameter of the two files, the operator pushes the concrete file suspended in the air to the shoulder so as to align the outer diameter of the lower file F1 with the outer diameter of the upper file F2. However, The crane must be lowered while the operator pushes the file of the crane, and the upper crane must be seated on the lower crane. Therefore, there are considerable inconvenience to the crane and safety accidents that the crane is seriously injured by the crane.

As a technique for solving such a problem, a guiding device formed like a funnel is disclosed in a "guide device for connecting concrete files" (Korean Patent Laid-Open No. 10-2010-0092290, Patent Document 1).

Patent Document 1 discloses that when a funnel-shaped guide device is installed on the head of a lower pile, when the upper pile pulled by the crane is positioned on the lower pile, the funnel-shaped guide device guides the outer pile of the piles up and down So that they can be matched.

Such a patent document 1 will exhibit a very good effect in improving the assembling accuracy in the method of connecting the files by the welding method.

However, as shown in the " connection structure of pile for soft ground reinforcement "(Korean Utility Model Registration No. 20-0277683, Patent Document 2), in recent years, in order to increase the ease of construction, A plurality of holes are radially formed on the upper surface or the lower surface of the connector so as to be connected to the upper file or the lower file, and a steel bar or a bolt protrudes from the lower portion of the connected file. , The upper file provided with the connector is merely axially aligned with the lower file, so that the assembly is not performed.

Specifically, the assembly hole formed in the connector and the steel wire or bolt formed to protrude from the lower file must be engaged with each other.

In addition, bolt assembly work must be performed in the side space of the connector after the fitting type.

Therefore, not only the axial center of the upper file and the lower file is made to coincide, but the upper file is rotated in the circumferential direction in order to make the assembly hole, the steel wire or the bolt straight.

However, in the existing operation method, the operator holds the connector of the upper file suspended by the crane by hand, and in this process, the signal is not transmitted due to lack of communication with the driver of the crane, It is possible to cause a large injury on the hands of a worker.

In other words, it is necessary to develop a guiding mechanism that merely coincides the axes of the files with each other and a mechanism that guarantees safety when the operator is able to finely rotate the upper file in the circumferential direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a safety support apparatus for a file connection using connectors and bolts according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the safety support device for a file connection using a connector and a bolt according to the present invention has an assembly hole 2b formed at the upper and lower ends of the upper file 1a as shown in the drawing, And the lower pile 1b to be assembled with the connector 2 is applied to a case where a steel wire or a bolt 1c to be fastened to the assembly hole 2b is protruded.

At this time, the assembly hole 2b may have a peanut shape as shown in the drawing, may be simply a circular hole, and may be formed radially along the circumference as a whole.

As shown in the figure, the bolt installation space 2a in which the bolt can be installed on the side surface is formed in the connector 2 so that the operator may perform the bolting operation from the side through the bolt installation space 2a. But is not limited thereto.

The winding band 10, which is a constituent element of the present invention, can be made of various materials such as plastic, fabric, leather, iron, rubber, etc., which can wrap and fix the file 1.

Of these, a hard metal plate, a fabric having flexibility rather than a plastic plate, a leather, or the like is most preferable.

In the case of a hard metal plate or a plastic plate, it can not be applied to files of various diameters and can not be firmly tightened by tightening the file. Thus, after the knob member 20 is installed, the knob member 20 is idle On the other hand, when it is made of a material having flexibility such as leather, fabric, etc., it can be applied to a file having various diameters, and the knob member 20 can be prevented from being idle.

As shown in Fig. 1, the handle member 20, which is a component of the present invention, has a band through hole 21 formed therein, so that the winding band 10 penetrates inward, and the outside has a handle shape Take shape.

The shape of the outer peripheral surface of the handle 20 may be a rod shape or a lever shape that is easy to grasp by hand, and the material may be made of various materials such as metal and plastic.

At this time, it is preferable that the inner circumferential surface of the pull member 20 does not slip during the operation of the operator in a state where the inner circumferential surface of the pull member 20 is in contact with the pile 1. [

When the winding band 10 is tightly adhered, the movement of the winding band 10 is suppressed. However, when the operator applies a force for finely rotating the pile 1 while gripping by the operator, the force is uniformly applied to the pile 1 It is desirable to be able to deliver.

1, it is preferable that the pull-tab 20 is provided with a flexible cushioning material 22 on the side thereof in contact with the pile 1. Further, the cushioning material 22 is provided with an irregular surface It is preferable that the friction material 23 is attached.

This configuration is advantageous in that the grip member 20 is firmly fixed to the pile 1 by the compression of the cushion material 22 and the friction force of the friction member 23 so that when the pile 1 is rotated by holding the pull member 20, 20 can be prevented from being idle.

Although only one handle member 20 is illustrated in the drawing, a plurality of handle members 20 may be provided.

The pull member 20 may be configured to be completely fixed to the take-up band 10 but is positioned to be able to move along the take-up band 10 through the through hole 21 as shown in the figure It is preferable that the winding band 10 is fixed after being brought into close contact with the pile 1.

The clamp 30, which is a component of the present invention, is installed on one side or both sides of the winding band 10 to fix the winding band 10 in close contact with the pile.

As a representative type of the clamp 30, there is a buckle type. Among them, it is most preferable to include an automatic bar, a ratchet buckle.

This makes it possible to firmly attach the winding band 10 to the pile 1 during the fixing process, thereby preventing the pinching of the pulling band 10 after the pulling member 20 is fixed.

Fig. 6 shows an example in which a ratchet buckle is provided in a winding band, and Fig. 7 shows an example of a knob.

An operation state according to the above configuration is shown in Fig.

The figure shows a state in which the operator grips the handle member 20 and turns the upper file 1a in the circumferential direction while the support device of the present invention is completely fixed to the upper file. The assembling between the assembly hole 2b and the steel wire 1c can be carried out smoothly when the upper file 1a is lowered onto the lower pile 1b by the operation of the crane, It is possible to secure safety.

In general, the file 1 is so heavy that the distance that the operator can grasp the handle member 20 is a very small distance, but it may nevertheless cause more rotation.

In the process of connecting the assembling hole 2b and the steel wire 1c at the time of connection between the files, not only the operation of rotating the file 1 in the circumferential direction is performed, but the operation of rotating the position of the upper file 1a A fine displacement operation may occur at the same time.

At this time, the pulling force of the worker is directly applied to the pulling member 20, but it may be difficult to sufficiently cope with the force only by the individual.

In view of this point, as shown in Fig. 3,
