Here, the screw jack 220 is variable, so that the spread band form 300 is in complete contact with the lower surface.

Preferably, between the third step and the fourth step, the work band form 350 is installed in the pier pillar 10 below the support rod member 100 and the hand is perpendicular to the end of the work band form 350. It is good to prevent the worker from falling by installing the rail pipe 360 vertically.

In the fifth step according to the present invention, the main form 50 is installed on the lateral beam member 20 and the longitudinal beam member 30 to the upper side of the spread band form 300, and the lateral beam member 20 is reinforced to support each other. The forming of the member 400 is performed.

The main form 50 is installed on the upper side of the spread band form 300 so that concrete is poured into the horizontal beam member 20 and the vertical beam member 30 as a general formwork.

Here, the main form 50 is divided into a plurality of foams and installed by the structural shapes of the lateral beam member 20 and the longitudinal beam member 30.

Preferably, the main form 50 is formed on the spread band form 300, the lower side form 52 and the lower side formed on the lower side of the horizontal beam member 20, the lower side form 52 is formed on the longitudinal beam The intermediate side article 54 formed below the member 30 and the upper side form 56 formed above the intermediate side article 54, and the lower side foam, the bottom foam 57 on the upper side Is installed, the top side foam 56 is preferably a top tie 58 is formed on the top.

Preferably, the main form 50 is preferably formed in plurality continuously.

First, the lower side form 52 is installed on the spread band form 300. Here, the lower side form 52 is installed in the longitudinal direction of the lateral beam member 20, and is coupled by various fastening members (bolts, nuts, screws, nails, etc.).

In addition, since the width of the longitudinal direction of the lateral beam member 20 is not constant, the lower side form 52 can be connected to a plurality of lateral beam member 20 in the longitudinal direction of each other.

Then, in order to close the upper portion of the lower side foam 52, a bottom foam 57 covering the upper side is installed.

This is for concrete to be poured on the basis of the bottom foam (57).

Next, the reinforcing member 400 for supporting the transverse beam member 20 is formed.

This is because the lateral beam member 20 is required to support the load of the longitudinal beam member 30, so as to increase the mutual coupling force.

That is, since the reinforcing members 400 are installed between the lateral beam members 20, the horizontal beam members 20 do not shake or shift left and right about the piers 10.

Preferably, the reinforcing member 400, in order to increase the mutual coupling strength of the lateral beam member 20, one side is in contact with each of the lateral beam member 20, the other side is formed in the spread band form 300 It is good to be.

This is to allow one side of the reinforcing member 400 to be in contact with the lateral beam member 20 to be coupled to each other, and to support the other side to be caught by the spread band form 300.

More preferably, the reinforcing member 400 is inserted into the upper square plate 410 and the upper square plate 410 vertically connecting the lateral beam member 20, the spread band form 300 And an anchor 420 penetrating the bar foam, an upper coupling bolt 430 coupled to the anchor 420 to press the upper square plate 410, and coupled to the anchor 420 below. The lower band form 300 is preferably made of a lower coupling bolt 440 tightening the lower side.

The upper square plate 410 is a steel steel plate in contact with the upper side surface of the lateral beam member 20, the upper coupling bolt 430 compresses the upper square plate 410, the horizontal beam member 20 is opened or It keeps you from moving.

The anchor 420 is inserted into the upper square plate 410 to pass through the spread band form 300 and the bottom form (57).

Therefore, the upper coupling bolt is coupled from the upper side of the anchor 420 to tighten the upper square plate 410 from the upper surface, the lower coupling bolt is coupled from the lower side of the spread band form 300 lower surface Tighten.

As a result, the horizontal coupling member 20 is prevented from being opened or moved by the pressing force of the upper coupling bolt and the lower coupling bolt up and down.

Next, the intermediate side article 54 is installed along the upper side of the lower side form 52. Here, the height of the intermediate side article 54 does not exceed the upper surface of the transverse beam member 20.

Next, the lower side surface of the upper side foam 56 and the upper side surface of the intermediate side article 54 are fastened through the fastening member.

Preferably, the upper side form 56 is formed with a plurality of insertion grooves 59 on the lower surface, it is preferable that the longitudinal beam member 30 is inserted into the insertion groove (59).

In addition, the horizontal beam member 20 may be provided with a hinge 21 on the open upper surface, which may be opened and closed by a hinge, and then the gap between the gate and the horizontal beam member may be finished with silicon.

In detail, since the lateral beam member is formed in an 'H' shape, concrete may be introduced into the space opened at the time of concrete placement, and thus, a gate that can be opened and closed by a hinge is installed on the upper surface of the lateral beam member to prevent this. In addition, the gap between the gate and the lateral beam member may be treated to finish with silicon.

This is because a plurality of the horizontal beam members 20 are coupled in the longitudinal direction of the longitudinal beam member 30, so that the longitudinal beam members 30 are pinched through the insertion groove 59.

Next, the top tie 58 is formed on the upper side form 56.

Then, when the main form 50 is all installed, the concrete is poured to cure.

Preferably, the length of the stability beam 420 protruding horizontally from the spread band form 300 and the end of the stability beam 420 is inclined to contact the outer peripheral surface of the lower side form (52) It is preferably supported by the variable inclined member 430.

This is to smoothly install the middle side article 54, the bottom form 57, the top side form 56 and the top tie 58, the stability beam 420 to the soup. It is installed horizontally outward from the red band form, the variable inclined member 430 is in contact with the lower side form 52 to adjust the length so that the lower side form 52 does not move.

And, the upper side of the inclined member 430, by installing a work band form 350, etc. to facilitate the work, the middle side product 54, the bottom form 57, the top side form 56 and the The top tie 58 is to be installed.
