Push the length adjustment pipe (80).

After the length adjusting pipe 80 is pushed into the pipe 50 by a predetermined distance, the length between the upper inclined protrusion and the lower inclined protrusion formed on the outer circumferential surface of the length adjusting pipe is positioned in the fastening hole 71 of the fixing bracket. The adjustment pipe 80 is rotated to one side so that the surface of the inclined protrusion 81a comes into close contact with the inclined surface 73 of the close contact protrusion 72 of the fixing bracket 70. At this time, the height adjustment of the length adjustment pipe is extended from the pipe length 50 when the second length adjustment pipe is pulled out from the pipe 50 in close contact with the inclined protrusion corresponding to the position of the fixing projection of the fixing bracket, and the length adjustment pipe is elongated. In the case of reducing the length of the second length control pipe to the pipe 50 to adjust the length and then adjust the length by stretching or reducing the length control pipe in such a way that the close contact and the inclined projection is fixed tightly.

The inclined protrusion 81a of the fixing bracket 70 is formed of an isosceles triangle, and the contact protrusions 72 formed on the length adjusting pipe 80 are formed of inverse isosceles triangles to contact and can bear a load applied thereto.

When the base plate 10 is located on the ground in combination with the above, the ground may be formed in a horizontal state or an inclined state.

Where the base plate 10 is installed on the ground level is installed in a straight state as shown in Figure 3, the base plate 10 is inclined as shown in Figure 4 base plate 10 along the ground It is located inclined.

However, the adjustment handle 30 coupled to the base plate 10 is maintained in a horizontal state by the adjustment mechanism 20 coupled to the lower screw 33 (see Fig. 4).

As shown in FIG. 4, if the inclination is not formed to the right and the inclination is formed to the left, the base plate 10 is inclined in the opposite direction instead of the same direction as in FIG. 4.

In the state in which the base plate 10 is installed as described above, by adjusting the position of the length adjusting pipe 80 installed inside the pipe 50 to support the belt.

At this time, even if the pressure of the load transmitted through the belt length can be maintained because the vertical state can withstand the load applied to the pipe (50).

As described above, the present invention has an effect that can be installed according to the inclined angle by using the base plate and the adjustment tool to bias the vertical load even if the ground of the construction site is inclined.

In addition, it is possible to fix the position of the length adjustment pipe by fixing the position of the length adjustment pipe by having a coupling structure where the close contact of the fixing bracket and the inclination protrusion of the length adjustment bolt are in contact with each other without using a fastening tool when adjusting the height. There is an effect that can withstand the load transmitted through the top plate installed in.

In addition, there is an effect that can maintain the verticality of the jack sut of the present invention through a coupling structure in which the inclined protrusion of the fixing bracket and the length adjusting bolt is in contact with each other without using the fastening tool when adjusting the height.

In addition, it is possible to reduce the installation time of the jack support because the length adjustment pipe can be rotated in and out to the inside of the pipe to adjust and fix its position.

In addition, it is fixed by using a fixing bolt, there is an effect that is easy to assemble, dismantle and transport at the work site without damaging the pipe.
