The present invention relates to an apparatus and a method for stably connecting a concrete cut file (70) and a base plate placed on the upper side of the file (70) (1) of the base plate.

The connecting device 1 between the file 70 and the base plate according to the present invention includes the blocking portion 10, the connecting portion 20, the boss portion 30, the binding portion 40, and the supporting portion 50 can do.

The blocking portion 10 is installed at a predetermined depth in the upper side of the concrete cut pile 70 and can be composed of a frame 11 and a blocking plate 12 coupled to the bottom of the frame 11 .

The frame (11) is formed to have a size smaller than the inner diameter of the pile (70).

The frame 11 may be formed in a polygonal shape corresponding to the number (six) of connection portions 20 to be described later, as shown in the illustrated example.

In this case, the number of the connection portions 20 and the shape of the frame 11 may be variously changed.

Although not shown in the drawing, a plurality of reinforcing ribs may be installed inside the frame 11.

The reinforcing ribs can be installed so as to intersect with each other, thereby improving the rigidity of the blocking portion 10 and preventing it from being bent by the loads of the living organisms.

The blocking plate 12 is formed to have a larger size than the frame 11 to close the bottom open portion of the frame 11. [

The blocking operation for the inside of the file 70 is completed by inserting the blocking unit 10 including the above configuration into the inside of the file 70. [

Therefore, when both living things are poured into the inside of the pile 70, both living things are accumulated on the upper side of the blocking plate 12.

In addition, a plurality of elastic fixing parts 13 are formed at regular intervals along the edge of the blocking plate 12. [

One side of the elastic fixing part 13 is rotatably connected to the blocking plate 12 in an upward direction or a downward direction.

The elastic fixing part 13 is in contact with the upper end of the pile 70 in a state of being horizontal with the blocking plate 12 but when the blocking plate 12 is pressed downward and inserted into the pile 70, Downward along the inner wall of the upper portion 70 and upwardly inclined.

A spacing portion 44 spaced apart from each other along the edge of the body portion 41 is coupled.

At this time, the gap holding portion 44 is located between the supporting portions 50 and is connected to only three surfaces of the body portion 41 formed in a hexahedron so as to avoid interference with the sediment filled in the pile 70 .

The spacing maintaining portion 44 contacts the inner surface of the pile 70 when the pavement 10 is installed inside the pile 70 so as to maintain the spacing between the body 41 and the pile 70, (40) is not moved, and the blocking part (10) connected via the supporting part (50) can be stably fixed in the inner space of the pile (70).

The contact member 42 is formed in a substantially semicircular shape so as to cover the connection portion 20, and both ends are connected to both side portions of the inner side edge of the body portion 41.

The contact member 42 is made of a material having elasticity and is elastically stretched when the connection portion 20 is inserted and then presses the central portion of the connection portion 20 to fix it to the body portion 41.

In addition, fixing holes 41a are formed on the respective corners of the body portion 41 so as to be positioned on the horizontal line with the contact member 42. A pressing blade 43 for dividing the inner space of the fixing hole 41a and the contact member 42 is formed on the body 41 so as to be inclined toward the fixing hole 41a.

At this time, the pressure wing portions 43 are formed as two pairs, and the opposite ends of the pressure wing portions 43 are spaced apart from each other to connect the inner space of the fixing hole 41a and the sealing member 42. [

A wedge portion 60 for pressing and fixing the connection portion 20 fixed to the tightening member 42 is inserted and fixed in the fixing hole 41a.

At this time, the wedge portion 60 may be formed such that the surface of the body member 61 facing the support portion 50 is inclined, and the pressing member 62 is formed on the opposite surface of the wedge portion 60.

The body member 61 is placed on the fixing hole 41a so that the bottom surface of the pressing member 62 covers the upper surface of the pressure wing portion 43 and then the wedge The body member 61 is forcedly inserted into the fixing hole 41a and stably fixed when the upper surface of the pressing portion 62 is repeatedly struck, The connecting portion 20 is kept in a rigid fixed state without being detached from the binding portion 40 and the boss portion 30. As a result,

Further, when the body member 61 is inserted into the fixing hole 41a, the pressing wing portion 43 is pushed to press the connecting portion 20, so that the structural stability of the connecting portion 20 can be further secured.

The supporting part 50 fixes the blocking part 10 on the pile 70 and supports the load of the living creatures filled up on the blocking part 10, (41), and are coupled to the respective corner portions of the body portion (41).

Each support portion 50 extends horizontally on the outer surface of the binding portion 40 and extends over the top of the pile 70.

In addition, a movement restricting jaw 51 may be further formed on the bottom surface of the support portion 50.

When the support portion 50 is seated on the upper end of the pile 70, the movement preventing pawl 51 can keep the pile 70 separated from the inner wall surface of the pile 70. However, in the course of construction of the present invention, And other assemblies associated therewith are unnecessarily moved, they are in contact with the inner wall surface of the pile 70, thereby restricting the movement and preventing excessive movement.

At this time, as shown in FIG. 1, the movement restricting tails 51 are formed in only three support portions 50 out of the six support portions 50 in order to avoid interference with the precipitate (latency) in the pile 70, For example, only at the support portion 50 located at 2 o'clock, 6 o'clock and 10 o'clock on the basis of the figure.

The number and position of the movement restricting tucks are not limited and can be variously changed by the operator depending on the field conditions.

Hereinafter, a method of assembling the connecting device of the file 70 and the base plate according to the present invention, and the unique effects appearing in the process will be described.
