Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-speed disconnectable quick connect device for a release file, and a file construction method using the same. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to a method and apparatus for quickly connecting a top and bottom separated fast connection device for a release file, and more particularly, to a method and apparatus for easily connecting a file of different materials and simplifying a connection process for extending a length of a file And it is possible to reduce the manufacturing cost of the connecting device and to perform the assembling of the connecting device at the factory or on site and to improve the connection strength, And a construction method.

Generally, in the case of civil engineering works or construction work on the ground, concrete piles are put in order to reinforce the ground, and foundation work is carried out thereon.

Such concrete piles are widely used for foundation work of buildings because they are relatively inexpensive to manufacture and have high resistance to vertical load.

And concrete piles have different depths to be embedded according to the ground conditions. In case of soft ground, two or more files may be piled up.

That is, the joint of the conventional concrete pile adopts a method in which a seat made of steel is installed at the end of the concrete pile and the pile is welded.

In the jointing method using welding, the seat made of steel is to be connected to the end portion of the concrete pile in advance. Depending on the presence or the position of the seat, various kinds of files such as upper, middle and lower connection concrete files and ordinary concrete files Should be produced and loaded.

The upper connection concrete file should be installed on the lower side with the left side panel. The middle connection concrete file should have the upper side and the lower side side plate. The lower connection concrete file should connect the upper side to the upper side.

However, many kinds of concrete files require the storage space in the file production site, and the cost due to the unnecessary inventory of the seat is increased.

Also, since the jointing method by welding requires welding at the construction site, it takes a lot of time for the jointing and the environment around the construction site is poor, so that a perfect joint can not be expected.

Therefore, in recent years, there has been developed a joint device which is fastened with a bolt and connected to solve the above-mentioned conventional problems.

The above-mentioned joint device of the bolt fastening system includes Korean Patent Registration No. 10-835778 (name: detachable coupling device for concrete file), and the detachable coupling device for the concrete file of Korean Patent No. 10-835778 As shown in the Gazette, an upper disk having an inner diameter equal to the inner diameter of the hollow portion of the upper concrete pile at the center, an outer diameter equal to the outer diameter of the upper concrete pile, and a through hole at a position corresponding to the PC nut of the upper concrete pile A lower circular plate in which a hollow portion having the same inner diameter as the hollow portion of the lower concrete pile is formed in the central portion and the outer side is the same as the outer diameter of the lower concrete pile and the through hole is drilled at a position corresponding to the PC nut of the lower concrete pile, And a connecting vertical member integrally connected between the lower disk and the lower disk, An annular ring which connects between the edge of the auxiliary disk and the edge of the lower disk and has a through hole formed at every circumferential interval and at least one of which is cut in the vertical direction, And a bolt threaded through the through hole of the annular ring and fastened to the bolt hole of the center pipe.

In the conventional concrete pile joint device having the above-described structure, since the anti-pulling force is uniformly distributed by the annular ring and is transmitted to the lower portion, breakage and deformation of the lower pile and the joint device do not occur, thereby strengthening the joint strength.

In addition, since the jointing device is used at the construction site, it is not necessary to prepare various types of concrete files and a large amount of jointing devices in advance, thereby reducing the amount of inventory, It is easy to work on the construction site because it is possible to do solid jointing work.

The above-mentioned joint device for a concrete pile with a bolt-fastened shape requires a large number of bolts to be fastened when bolts are fastened to the connecting vertical member by an annular ring (outer ring) There is a problem that productivity is low.

In addition, when both ends of the annular ring (outer ring) are fixed while being in contact with each other, there is a problem that both ends of the annular ring (outer ring)

That is, both end portions of the annular ring have end portions in the shape of a vertical straight line, so that there is a problem that both ends are widened when used for a long time.

Also, the volume of the upper disk, the lower disk, and the connecting vertical member are so large that they are not easy to transport and store, and the productivity is low due to inconvenience in manufacturing.

In order to solve the above-mentioned problems, a joint device for a concrete pile developed has a top plate having a fastening hole to be fastened with a fastening bolt at the tip of an upper concrete pile, a fastening hole to be fastened with an upper end of the lower concrete pile, Wherein the connecting block is composed of two or more connecting blocks including a bottom plate and a vertical plate vertically connecting the top plate and the bottom plate so that the connecting blocks are circularly formed in a plane, Wherein the upper plate and the lower plate are extended to the front surface of the vertical plate and the annular outer ring is coupled to the front surface of the vertical plate having the edge portions of the upper plate and the lower plate, And both ends of the ring are provided on the side in which the bending grooves are in close contact with each other so as to be in close contact with each other.
