Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

In addition, although the wind form die according to the present invention has been described as an embodiment the wind form form for pouring the wind formed between the two tunnels, but is not limited to this, it is possible to implement a variety of forms of wind form.

The windage formwork installation, demoulding, moving system 100 according to the present invention is composed of the frame portion 27 and the outer portion, as shown in [FIG. 1], although not shown in the figure, the formwork demoulding and moving apparatus ( 50).

The frame part 27 serves to form the inner skeleton of the wind-dice form, in the embodiment of the present invention used a truss (truss) that is a frame structure connecting the connection point with a pin so that the member is not bent.

The truss has only the effect of tensile force and pushing force, and it does not bend, so there is little waste of material and there is an advantage of spanning a large space by combining short rods.

In addition, as shown in FIGS. 2 and 3, a second cylinder portion 11 vertically connected to the upper plate 10 is formed at an upper end of the frame portion 27.

The second cylinder portion 11 serves to raise or lower the height of the upper plate 10 during installation and demoulding of the wind-mould formwork 100.

The outer portion is composed of a skin plate, a reinforcement 29 and a waller 25.

The skin plate forms the outer surface of the wind-dice formwork 100 and is connected to a plurality of panels, and consists of an upper plate 10, two side plates 20 and 30, and a lower plate 40, between two arched tunnels. Since it is installed, the size of the lower plate 40 is narrower than the size of the upper plate 10 in the form of an inverted triangle as a whole in cross section.

In addition, the side plates 20 and 30 form a curved surface.

The reinforcing material 29 serves to prevent shear reinforcement and buckling of the web portion of the skin plates 10, 20, 30, and 40, and uses a stiffener in the embodiment of the present invention.

The stiffener is a member that is used as a reinforcing material to prevent buckling because a buckling phenomenon occurs when steel is bent at a predetermined value or more when a load is applied in a steel structure.

The waller 25 is an auxiliary mechanism that vertically couples the connection lines of the skin plates 10, 20, 30, and 40 to prevent misalignment between the panels.

A cutout is formed on the upper plate of the outer portion, that is, the skin plate side plates 20 and 30, and folding portions 13 and 23 are formed to fold a part of the side plate into the wind form based on the cutout. .

The driving wheel 55 serves to support the load of the entire wind-dice formwork when demolishing the wind-up formwork.

The driving wheel 55 is composed of two side by side and the center is connected.

The driving wheel 55 touches the floor or slab through the open through part 60 formed in the lower plate 40 of the formwork 100.

That is, the driving wheel 55 is in contact with the floor or the slab, to support the entire formwork load.

As such, the driving wheel 55 supports the entire formwork and moves when the mold is demolded, and thus the center of the driving wheel 55 is made of a solid metal material, and the outer surface surrounding the center is made of a rubber material. It is preferable that it is comprised from raw materials.

In addition, the driving wheel 55 is stable to be formed at least one or more to secure the center of gravity with respect to the load of the entire air-winding formwork.

In addition, since the driving wheel 55 is rotatable, the driving wheel 55 supports and moves the formwork through rotation.

The third cylinder (51) is characterized in that the piston 52 inside the linear reciprocating motion as shown in Figure 8, one side is hinged to the lower plate 40 of the wind turbine form 100 do.

That is, although one side of the third cylinder portion 51 is fixed to the lower plate 40, the other side of the cylinder portion 51 can be moved side to side with reference to the white paper by fixing the white paper.

One side of the connection portion 57 is connected to the driving wheel 55 and the other side is connected to the third cylinder portion 51 to drive the force generated by the linear piston reciprocating motion of the third cylinder portion 51. It serves to convert the height of the wheel 55 to a force to raise or lower.

In addition, the connection portion 57 according to the present invention is preferably formed in a form in which one side and the other side is bent at a predetermined angle, not a straight line, the bent point is fixed to the bottom of the form of white paper, the third cylinder portion 51 And acts as a lever between the drive wheel (55).

In the embodiment of the present invention, the connecting portion 57 has a shape of 'b' bent at approximately 90 ?? 'between one side and the other side and has three connection points.

FIG. 8 is a side view of the formwork demoulding and moving device 50 according to the present invention installed in the wind formwork 100.

The first connection point and the second connection point, which are end portions of 57, may be moved left and right based on the side view.

In the present invention, the connection portion 57 is a bent form in the center 'b' form, it can be configured in various angles or forms that can serve as a lever.

8 and 9 are views illustrating the operation of the mold demoulding and the moving device. When the inner piston 52 protrudes to the outside by the linear reciprocating motion of the cylinder 51, the cylinder 51 The overall length is long.

At this time, the second connection point 573 connected to the distal end of the piston 52 also moves in the same direction as the movement direction of the piston 52.

That is, the second connection point 570 is a force point by the principle of the lever, and the third connection point 575 is a support point.

At the same time, since the first connection point 571 connected to the center of the driving wheel 55 is lowered toward the bottom, the driving wheel 55 is also lowered.

That is, the first connection point 571 is an operating point of the force acting on the drive wheel 55.

In addition, in the embodiment of the present invention, the fixing groove 65 is further provided on the side of the wind die 100, and serves to fix the height of the driving wheel 55 descending the fixing groove 65.

In more detail, when the driving wheel 55 is lowered by the third cylinder part 51, the center projecting to the outside of the driving wheel 55 comes into contact with the fixing groove 65, and the driving wheel ( 55) can no longer descend.

As such, when the driving wheel 55 is lowered by the cylinder part 51 and reaches the bottom, the driving wheel 55 lifts the wind-mould formwork 100, and the lower plate of the wind-mould formwork 100 The difference between the floor and the height of 'H2' will occur.

When the wind vane 100 rises as much as 'H2', the driving wheel 55 can be rotated, so that when the force is applied from the outside of the wind vane 100, it can have a moving force.

In addition, the formwork demoulding and moving apparatus according to the present invention was further provided with a motor portion (53).

The motor unit 53 is connected to the central portion of the drive wheel 55, thereby increasing the rotational force of the drive wheel 55 serves to facilitate the movement of the wind die 100.

In addition, when the motor unit 53 is provided, the driving wheel 55 can be rotated without applying a separate force from the outside.

The motor unit 53 may use various types of motors that enable the driving wheel 55 to be rotatable, and the motor unit may be understood by a known technique, and thus detailed description thereof will be omitted.

If the length of the windage formwork is long, such as tunnel construction, as shown in FIG. 10, if the windage formwork demoulding device is installed at a predetermined interval, the windage formwork demoulding and moving work is more easily performed.

In addition, the windscreen formwork installation, demoulding, moving system further comprises a nose portion 300 connected to the frame portion 27 or the outer portion.

The nose portion 300 is connected to and fixed to the outer portion or the frame portion 27 from the outside to pull the front of the wind-dice formwork 100, and serves to facilitate the movement.

In addition, the formation of the nose portion 300 is also effective in reducing damage in the form of the wind-air formwork (100).
