And further includes a column fixing member 30 fixed to the upper end of the column 41 and fitted to the inner member 10 and fixed by at least one screw inserted sequentially from the housing member 20 It is possible.

In more detail, the inner member 10 includes a connecting surface 11, a first intermediate surface 13, and a jaw 15.

First, the connecting surfaces 11 are formed as a pair arranged at an angle of 90 degrees.

In addition, since each of the connecting surfaces 11 has the recess 11 'formed with one or more screw holes 11' ', waste of raw materials can be prevented and weight can be reduced.

A protrusion 17 in the vertical direction is formed on the outer edge of each connecting surface 11.

4, each of the protrusions 17 may be formed to be inclined downward toward the inside, but the upper and lower ends may be formed in a vertical direction, or may be vertically formed from the upper end to the lower end And may be formed in a shape inclining downward from the top to the bottom.

The projection 17 serves to engage the inner member 10 with the housing member 20, which will be described in conjunction with the housing member 20.

Next, the first intermediate surface 13 serves to connect the connecting surface 11.

Also, a concave portion 13 'is formed on the rear surface of the first intermediate surface 13 and at least one screw hole 13' 'is formed in the intermediate portion.

3, a screw hole 13 "formed at the center of the first intermediate surface 13 is formed to be screwed with the housing member 20, and a screw hole 13 " A head hidden groove 13 '' 'may further be formed in another screw hole 13' 'formed above and below the screw hole 13' 'formed at the center.

The threaded hole 13 ", in which the head hidden groove 13 "" is further formed, is formed in the screw hole 13" 13 ") is inserted into the first intermediate surface 13 more deeply than the first intermediate surface 13 without protruding.

The concave portion 13 'formed on the rear surface of the first intermediate surface 13 has the same effect as the concave portion 11' formed on the connecting surface 11. [

Next, the jaw portion 15 is protruded forward from the upper portion of the connecting surface 11 and the first intermediate surface 13.

In addition, a partial thread groove 15 'is formed at a central corner portion to be screwed with the housing member 20.

The jaw 15 protruded forward from the upper surface of the connecting surface 11 may have at least one separating groove 18 opened downward.

When the housing member 20 and the inner member 10 are to be separated from each other, the separation groove 18 is formed in the housing member 20 so as to easily separate the housing member 20 and the inner member 10 from each other after the clearance is formed by slightly fitting a sharp- 20 and the inner member 10 from each other.

Next, the housing member 20, into which the inner member 10 is inserted and which is engaged with the upper plate fixing base 43, includes a fixing portion 21, a connecting portion 23, an intermediate portion 25, and a receiving piece 27 .

A pair of the fixing portions 21 are formed in a shape corresponding to the angle of the upper plate fixing table 43 so as to be fixed in contact with the upper plate fixing table 43.

More specifically, the fixing portion 21 is provided with at least one through hole 21 'and is screwed and fixed to the upper plate fixing table 43.

Next, the connection portion 23 is formed in a frame shape extending to the fixing portion 21 so as to be parallel to the upper plate fixing table 43.

Since the connection portion 23 is formed in a frame shape, unnecessary waste of raw materials is reduced and weight is reduced, and screwing to each of the concave portions 11 'is facilitated.

The connection part 23 may be provided with a separation part 28 at a position corresponding to the separation groove 18 of the jaw part 15.

The use of the separating portion 28 is the same as that of the separating groove 18, and thus a detailed description thereof will be omitted.
